A NOTE TO THE READER:

There is some material you should be aware of that is not presented in this book (I) Grisly photographs showing the results of suicide attempts; (2) detailed information about specific drugs: dosage, overdose, and toxic effects. Both of these will be available at my website (under construction), as are links to other suicide-related sites of all persuasions. There will also be an opportunity to make suggestions and corrections to the text there. Please do: all of us are smarter than any of us.

Attempting suicide is not a game or sport. This book was written to enlighten its readers on the general subject of suicide. Beyond the dissemination of general historical and statistical information, this book provides information that might save the lives of those who attempt suicide, as a means of seeking help, but who do not actually intend to end their lives. This book also provides information that might ease the physical pain of those who have made the decision to end their lives. This book is absolutely not intended to encourage anyone to attempt or to commit suicide.

SUICIDE AND ATTEMPTED SUICIDE

INTRODUCTION

Razors pain you; Rivers are damp; Acids stain you; And drugs cause cramp; Guns aren't lawful; Nooses give; Gas smells awful; You might as well live. —Dorothy Parker; "Resume," 1926 This book describes, in sometimes-gory detail: (1) methods people use to commit suicide; (2) the medical consequences of suicide attempts; (3) how to carry out a safe suicidal gesture; (4) how to commit suicide as nontraumatically as possible. You may find parts of it disturbing. But the consequences of ignorance are more disturbing: botched suicides, accidental deaths and maimed survivors, slow and painful deaths. Every eighteen minutes someone in the United States kills himself. A few are younger than ten years old; others over ninety. Between 7.5 and 16 percent take more than a day to die. An estimated 300,000 to 600,000 survive suicide attempts, but suffer varying degrees of injury; 19,000 are permanently disabled each year. Only about one in ten or twenty suicide attempts is fatal. Given the easy 3

2 • Geo Stone availability of highly lethal methods, the conclusion must be that most people who attempt suicide don't want to die. Yet, many people who didn't intend to die succeed in killing themselves. Most lack knowledge of drugs and may unknowingly take a lethal overdose; some expect rescuers to save them. Others, who are really trying to die, live through their attempts. Many survive five-story jumps or head-in-the-oven gassing. Few have an accurate idea of how dangerous their chosen method is or of the consequences should their attempt fail. Throughout this book, I try to provide evidence of the medical effects of each suicide method so that you can make more realistic decisions if you're thinking of suicide. For the same reason I also cite the sources of my information so that you can look at the original data unfiltered through my interpretations, biases, or errors. Statistics, though informative, diminish the impact and reality of death. While this book is filled with figures and abstractions, behind each of these numbers is a real person, with a history, personality, and pain that is both particular to the individual and common to us all. These are not just numbers; these are our friends, and neighbors, and families, and selves. I include some of their words to give a sense of the quality of their lives, and the thinking that led to their choice of suicide. For example, listen to Karen, age sixteen, describe the situation that brought on her suicide attempt: I was really upset and depressed. My life just seemed to be in total chaos. My boyfriend just dumped me flat, and he said he loved the other girl and didn't love me at all. My parents and I also just got into another fight again about some really dumb things, so I just went into my room and closed the door. There was this bottle of sleeping pills my mother was using, and I had them with me. I sat and stared at it for a long time, weighing out the good and the bad things in my life. The bad things came out ahead. I poured some of the pills in my hand, and figured ten or fifteen ought to be enough to do it. Those pills... they all looked so innocent and peaceful, like they couldn't do much to hurt anyone. Well, I put them in my mouth and held them there for a long time, wondering if I should or shouldn't. I took a glass of water and swallowed. At first nothing

Suicide and Attempted Suicide • 3 happened, and then they all hit me at once. The room started to blur and spin, small sounds were going on in my head. The last thing I remembered was trying to move and not being able to. I woke up in the hospital. They were pumping out my stomach—one of the worst things you can have done to you. My mother came into the room, and she apologized for the fight we had. 3

The material here is intended both for those who want a quick and relatively painless death, and for those who want to carry out a suicidal gesture as safely and noninjuriously as possible. If it convinces some potential suicides to seek other solutions—suicide should be an absolutely last resort and mistakes may leave you crippled—so much the better. But the fact remains: there is no way to limit this knowledge to those whose aims we agree with. To make my premises explicit: (1) Decisions concerning your death should be, ultimately, yours to make; (2) most—but not all—decisions to commit suicide are due to temporary problems and are therefore tragic mistakes. My position comes from two principles: (1) self-determination and (2) mercy. The more fundamental, self-determination, says that each competent person may decide and act on (subject to noninterference with the rights of others) his or her own views of what constitutes a good life and death. In practice, I think that temporary suicide intervention is appropriate when there is another reason to believe that someone's thinking is impaired (e.g., by depression), though both the nature (reversible) and timecourse (brief) of the intervention should be limited. The principle of mercy holds that no one (or thing) should be made to suffer unnecessarily. This is necessarily the subordinate principle; one may choose to suffer for some perceived higher good. While mentioned in this book, these ethical and philosophical issues are treated in much greater detail elsewhere. (See suggested readings.) For those who are religiously, philosophically, or ethically opposed to suicide under any circumstance, this publication will be of little comfort; those who believe that it is each person's right to decide, insofar as possible, when to die may find some answers to their questions and fears.

4 • Geo Stone Just as I shall select my ship when I am about to go on a voyage, or my house when I propose to take a residence, so I shall choose my death when I am about to depart from life. —Seneca, Epistulae Morales

I place suicide attempters in one of four groups: (1) Rational people facing an insoluble problem, generally a fatal or debilitating illness; (2) impulsive people, frequently young, truly but temporarily miserable, often drunk, who wouldn't even consider suicide six months later; (3) irrational people, often alcoholic, schizophrenic, or depressed; (4) desperate people, people trying to make a safe gesture as a "cry for help" or to get someone's attention. The first group—and most of us will eventually be in it—has, in my view, the right to decide the time, place, and manner of their death. They ought to have medical help to die peacefully and without pain, but this, while sometimes surreptitiously done, cannot at present be relied on. Many of us have known people who have suffered long, agonizing deaths because they became too ill to kill themselves and their physicians were unwilling to act on their request. I will not mince words by calling it "euthanasia" or "self-deliverance": If you're terminally i l l , I hope to provide you with information that will help you determine the best way to kill yourself—if that's your well-considered decision. What about the young and impulsive, particularly teenagers? At the moment, they seem to have the worst of all worlds, where: (1) lethal and notso-lethal suicide methods are readily available; (2) neither they, their parents, nor their teachers are likely to know how dangerous particular methods are; (3) personal ("Are you thinking about . . . ?) or practical ("How would you go about. .. ?) discussion of suicide is largely taboo. While many schools now teach about A I D S and its transmission, more teenagers will attempt or commit suicide next year than will become H I V infected. The ignorance, stigma, and fear about suicide would decrease if that topic were added to the curriculum and treated honestly. A case will be made that people shouldn't commit suicide and that, therefore, a manual telling them how to go about it is pernicious. This is like one of the arguments against sex education: "If they know how, they'll do it." Well, they do it anyway. Thirty thousand suicide deaths a year in the United 0

Suicide and Attempted Suicide • 5 States should make this clear. In the absence of knowledge about suicide methods—and alternatives to suicide—people will continue to act in desperation and ignorance, as they have throughout recorded history, with gun, rope, blade, poison, and anything else available. That is the reality. The methods people use, all too often leave them neither dead, nor fully recovered, but maimed and permanently injured: paralyzed from jumps, braindamaged from gunshots, comatose from drugs. But for anyone considering suicide (or even "safe" suicidal gestures; nothing is 100 percent reliable), I urge you to try every alternative first—and then try them again. These include a variety of antidepressant drug therapies, various flavors of psychotherapy, electroshock, and "reality therapy," which could be defined as helping people who are worse off than you. Each of these will work for some; no single solution will work for everyone. That's why it's vital not to give up if one or two or three different attempted "solutions" don't do much to decrease your pain. How do you know that suicide is the answer if you haven't tried everything else first? You can always kill yourself later. d

Every person's fight with death is lost before it begins. What makes the struggle worthwhile, therefore, cannot lie in the outcome. It lies in the dignity with which the fight is waged and the way it finds an end. —Joseph Fletcher I've known several people who have killed themselves, and others who i n tended to, but waited too long. Three have been significant influences in writing this book. One man had a series of small strokes and specified that if he had a major one he did not want so-called heroic measures used to save him. Soon afterward, he did suffer a massive stroke, which reduced him to a vegetative state, and he was kept alive contrary to his written instructions. His son, a physician himself, was appalled by the contravention of his father's instructions in a medically hopeless situation. Nevertheless, it took weeks of argument and delay before the hospital agreed to act in accordance with their wishes. Another man, eighty years old, entered a hospital intending to kill himself (he said) if he didn't get better. After four months and a series of operations, he became too weak and disoriented to act on his intention. He "lived" an-

PART I BACKGROUND

I A BRIEF OVERVIEW OF SUICIDE

Most people, in committing a suicidal act, are just as muddled as when they do anything important under emotional stress. Carefully planned acts of suicide are as rare as carefully planned acts of homicide. —Erwin Stengel 1

Dying is an art, like everything else. I do it exceptionally well. —Sylvia Plath,"Lady Lazarus" It seemed like a good idea ... at the time. —Anonymous Throughout the world, about two thousand people kill themselves each day. That's about eighty per hour, three-quarters of a million people a year. In the United States, there are more than eighty deaths from suicide every day, or about thirty thousand every year. This is the equivalent of a fully loaded jumbo jet crash every fifth day. From another perspective, you are more likely to kill yourself than be killed by someone else. Another estimated 300,000 (or more) Americans a year survive a suicide attempt. A majority sustain injuries minor enough to need no more than 2

10 • Geo Stone emergency room treatment. However, about 116,000 are hospitalized, of whom 110,000 are eventually discharged alive. Their average hospital stay is ten days; the average cost is $15,000. 4

Without knowledge of proper dosages and methods, suicide attempts are often bungled, leaving the victim worse off than before. Many intended suicides by gunshot leave the person alive but brain-damaged; drug overdoses that are not fatal may have the same effect. O n e eighty-three-year-old woman obtained an insufficient number of pills and lost consciousness but did not die; her daughter ended up smothering her with a plastic bag. 5

Seventeen percent, some 19,000, of these people are permanently disabled— restricted in their ability to work—each year, at a cost of $127,000 per person. Such injury is tragic, whether the person was trying to commit suicide and failed, or, perhaps even sadder, if the suicide attempt was intended not to cause death, but to serve as a "cry for help." About 1.4 percent of Americans end their lives by suicide, making it the eighth leading cause of death in the United States. Suicide ranks fourth as a factor in years of lost life. The largest increase in the last thirty years has been among people between fifteen and twenty-four years of age, but the highest rates are still among the elderly. M e n kill themselves at about four times the rate for women (19.8 in 100,000 for men versus 4.5 in 100,000 for women in 1994). Around 3 percent of adults will make one or more suicide attempts. There are more suicides than the official numbers show, but there is no general agreement as to how many more. Estimates of underreporting range from around 1 to 300 percent. Reasons for underreporting include: 6

1. Families or family physicians may hide evidence due to the stigma of suicide. For example, "Physicians and surviving relatives have told me in confidence of many deaths which were suicides, but which had been certified as natural or accidental deaths by a physician, either through error, misinformation, or deliberate falsehood.... My own estimate is that there were an additional 10,000 deaths yearly [in the United

Suicide and Attempted Suicide • 11 States] which would have been certified as suicides if there had been complete and impartial investigations." 10

2. The determination of cause of death is judged by local standards, which vary widely. In one egregious instance, a coroner would cite suicide only in deaths where a suicide note was found—and suicide notes are only found in around one-quarter of known suicides. 11

3. There are lots of ambiguous situations, some of which are suicides, but which almost always end up classified as "accidental" or "undetermined": the single-car accident with no skid marks; the fall off the night ferry; the stumble in front of the train; the inadvertent overdose; the gun-cleaning mishap. 4. Compared to the "accidental" or "undetermined" motive categories, there is a much larger number of deaths officially classified as "ill-defined and unknown causes of mortality," where even the actual cause of death is uncertain, and some of which are undoubtedly suicides. 5. The frequency of physician-assisted suicide for the terminally i l l is unknown, but, based on anecdotal evidence, is probably both substantial and increasing. More on this in the chapter, Assisted Suicide and Terminal Illness. 12

On the other side of the ledger, some doubtful cases are classified as suicides. These usually occur in institutions, such as prisons, hospitals, religious orders, and the military, which control their populations more or less completely. For such institutions a verdict of suicide is likely to be the least embarrassing (after "natural") cause of death: Homicides must be investigated and a murderer sought; accidents may be the basis of negligence lawsuits. The number of suicide attempts is also subject to dispute. Based on a range of studies, there are probably between ten and twenty attempts for every successful suicide, or roughly 300,000 to 600,000 attempts per year in the United States. Yet more than half of suicides kill themselves on their first try. The overall 3- or 4-to-l male-to-female suicide ratio in the United States is reversed for suicide attempts. Between 70 and 90 percent (studies differ) of suicide attempts are by medicine/drug overdoses, roughly 15 percent by wrist cuts. For adolescents, the attempt-to-fatality ratio may be 50:1, but this aver13h

12 • Geo Stone age masks the fact that the death rate for boys is one hundred times higher than for girls: around 10 percent and 0.1 percent, respectively. About 11 percent of high school students have made at least one suicide attempt. Ninety percent of adolescents' suicide attempts occur at home, and parents are home 70 percent of the time.

WHAT IS SUICIDE? The numbers above refer to acts formally classified as suicides, but the more one thinks about it, the less clear the boundaries become. Should we include refusing medical treatment in a terminal illness? What about a suicidal gesture gone awry? How about martyrdom? A n d what of the "little suicides": the high-speed drag race, the drunk drive, the picking of a quarrel in a bar? Among adolescents the combination of reckless (and inexperienced) driving with alcohol and/or drug use may be more dangerous than overt suicide attempts. In Man Against Himself Karl Menninger compiled some four hundred pages of self-destructive, or suicidal, behavior, ranging from making war to nail-biting. He divided these into three groups: "chronic" suicidal behavior includes alcoholism, martyrdom, psychiatric illness, and antisocial actions; "focal" suicide targets specific parts of the body, as in self-mutilation, or deliberate accidents; and "organic" suicide, where people supposedly lose their will to live and die of illness and disease that they would otherwise overcome. The items on his list, and subsequent additions to it, have been called "slow suicide" or "suicide on the installment plan." 1

20

21

A n d there is the daily suicide of depression and apathy, as described here by James Carroll: A thousand people are "officially" dead of suicide every day, but they are not the only ones who are faced with the constant choice between life and death. We all are.... We might lack the nerve to commit the final act, and we might not recognize our "sinful" tendencies for what they are, but day in and day out we confront the problem of our innate attraction to self-destruction. We live in a world that encourages the small daily acts of negation that prepare

Suicide and Attempted Suicide • 13 us for the great one.There are meanings of suicide that neither the courts nor the dictionaries admit, but that make it impossible for us to regard those thousand people a day who do themselves in as very different from us. They are not necessarily "sick" or "sinners," but simply our sisters and brothers. A n d who are we? We are the resigned housewives, the compulsive playboys, the despairing priests, the addicted teenagers, the reckless drivers, the bored bureaucrats, the lonely salesmen, the smiling stewardesses, the restless drifters, the walking wounded. . . . It may be nothing more than the steadfast commitment to sameness. The simplest form of suicide is the act of refusing the adventures and challenges that offer themselves to us every day. " N o , thanks," we say. "I prefer not to," we murmur, like Melville's Bartleby, preferring to stare at the wall outside the window. Preferring, as I do on especially bad days, to stay in bed. 22

If you play Russian roulette with a six-shooter, your odds of dying are one in six; if you climb M t . Everest they're also about one in six. The former is a generally condemned form of suicide; what, then, is the latter? Yet, Sigmund Freud wrote, "Life is impoverished, it loses in interest, when the highest stake in the game of living, life itself, may not be risked. It becomes as shallow and empty as, let us say, an American flirtation." 23

NOTES a

In addition to social and e c o n o m i c disincentives f o r p e o p l e to seek help, medical data is b o t h scanty and unreliable. F o r e x a m ple, of 72 p e o p l e w h o r e p o r t e d suicide attempts in an a n o n y m o u s survey, only 18 (25 percent) sought medical care and 7 ( 1 0 percent) w e r e hospitalized ( M e e h a n , 1992).

Similarly, the suicide rate in India (1972 data) was 7.8/100,000 but varied by state: f r o m 0.70 in Muslim J a m m u and K a s h m i r to 20.5 in H i n d u Kerala (Headley, 216). e

2 HISTORY OF SUICIDE

Death is before me today Like the recovery of a sick man ... Like the longing of a man to see his home again After many years of captivity ... — " M a n Disputing Over Suicide with His Soul," Egypt, ca. 2100 B.C. 1

The oldest known reference to suicide is Egyptian; a fragment is quoted above. There are seven suicides in the O l d Testament; none of them are criticized in that document. In the New Testament, the suicide of Judas seems to be implicitly condoned—it's mentioned without comment in Matthew 27:3—as a sign of his repentance; not until much later did the church claim that Judas's suicide was a greater sin than was his betrayal of Christ. Early Christianity was strongly attracted toward suicide, perhaps because the act was often indistinguishable from martyrdom, and, "even the death of Jesus was regarded by Tertullian, one of the most fiery of the early Fathers, as a kind of suicide. He pointed out, and Origen [another major early Christian theologian] agreed, that He voluntarily gave up the ghost, since it was unthinkable that the Godhead should be at the mercy of the flesh." 1

While early Christianity accepted suicide, it condemned killing others through warfare, in self-defense, and by capital punishment. After all, Jesus had taught nonviolence: "Do not resist one who is evil. But if anyone strikes 15

16 • Geo Stone you on the right cheek, turn to him the other also.... I say to you, Love your enemies and pray for those who persecute you." This was taken seriously by the early church fathers, for example, Tertullian, who asked, "Can it be lawful to handle the sword, when the Lord himself has declared that he who uses the sword shall perish by it?" However, as Christianity became the dominant religion in the Roman Empire, its views on suicide gradually changed, until suicide became a religious sin and a secular crime in the sixth century. In 533, Christian burial (a requirement for getting into heaven) was forbidden to suicides who killed themselves while accused of a crime. In 562 this was extended to all suicides, regardless of the reason or circumstances. In 693 even attempting suicide became an ecclesiastical crime punishable by excommunication, with civil consequences to follow. St. Augustine, in his fifth-century book The City of God, was the first Christian to make a blanket condemnation of suicide. His only biblical justification for the change was a novel interpretation of the sixth commandment, "Thou shalt not kill"; his other reasons were, as Rousseau noted, taken from Plato's Phaedra. Ironically, this well-intentioned and humanitarian opposition to suicide eventually degenerated into "legalized and sanctified atrocities, by which the body of the suicide was degraded, his memory defamed, his family persecuted." Suicides were buried at crossroads with a stake through their bodies, and their property was confiscated by the state. Perhaps the ultimate irony was the execution of people for the crime of attempting to commit suicide. A Russian exile in England, Nicholas Ogarev, wrote, 3

A man was hanged who had cut his throat, but who had been brought back to life.They hanged him for suicide.The doctor had warned them that it was impossible to hang him as the throat would burst open and he would breathe through the aperture. They did not listen to his advice and hanged their man.The wound in the neck immediately opened and the man came back to life again although he was hanged. It took time to convoke the aldermen to decide the question of what was to be done. At length the aldermen assembled and bound up the neck below the wound

We have progressed far beyond such barbarism, and no longer condemn failed suicides. Now, for example, if a death-row criminal attempts suicide, every effort is made to save him (or, more rarely, her), so that a civilized, state-approved execution can be carried out. Non-Christian societies have expressed a wide range of views about suicide. Buddhist, Confucian, and Shintoist ethics accept suicide and euthanasia in cases of incurable illness. The Vikings felt that Valhalla, with its perpetual Feast of Heroes and Gods, was reserved for warriors who died in battle. Suicides were second-best and might get to sit below the salt; people who died in bed could eat with the kitchen help and sleep in the barn. The Scythians considered it an honor to commit suicide when they could no longer keep up their nomadic travels, while "death, passively awaited, is a dishonor to life." Various schools of Greek philosophical thought rejected (Pythagoreans, Aristotle), conditionally accepted (Plato, Epicureans), or approved of (Stoics, Zeno) suicide. The Romans followed the Greek lead in these matters, particularly that of the Stoics. "To the Romans of every class, death itself was unimportant. But the way of dying—decently, rationally, with dignity and at the right time—mattered intensely." 6

The early Christians agreed that death was unimportant, but for entirely different reasons: They wanted to go to the glory of heaven and saw no good reason on earth to wait. Life was a gateway, filled with sins, snares, and temptations, all leading to eternal damnation. Thus they often invited persecution as a path to martyrdom, which automatically wiped the slate of any old sins, prevented new ones, and guaranteed a seat in paradise. This was carried to its logical conclusion by a sect known as the Donatists, of whom St. Augustine said, "to kill themselves out of respect for martyrdom is their daily sport." They were noted for jumping from cliffs, and also burned themselves to death in large numbers. They are probably best known for their practice of stopping travelers and either paying them or threatening them with death to encourage them to kill the, presumably, heaven-bound martyr. The Donatists were eventually declared heretics and suppressed with notable lack of Christian charity. 10

f

18 • Geo Stone M u c h later, the thirteenth-century Albigensian (Catharist) heretics in southern France were slaughtered with incredible savagery, also, in part, because they sought martyrdom. This sin compounded their damnation for other theological errors—for example, they had the temerity to believe that religious orders should actually practice their vows of poverty. Not until the late Renaissance—one thousand years after Augustine—did people again dare, very cautiously, to argue the case for suicide in Christian Europe. By the sixteenth century Roman and Greek philosophy had been rediscovered and the unconditional condemnation of suicide was being questioned. In Holland, Erasmus wrote In Praise of Folly (1509), in which he defended suicide which was committed to escape an unendurable life. Soon afterward Sir Thomas More, in his fictional Utopia (1516), proposed suicide for the purpose of euthanasia: They console the incurably ill by sitting and talking with them and by alleviating whatever pain they can. Should life become unbearable for these incurables the magistrates and priests do not hesitate to prescribe euthanasia. . . . W h e n the sick have been persuaded of this, they end their lives willingly either by starvation or drugs, that dissolve their lives without any sensation of death. Still the Utopians do not do away with anyone without his permission, nor lessen any of their duties to him. 11

Shakespeare (1564-1616), always theatrically pragmatic, portrayed fourteen suicides in his eight tragedies without condemning them, asking instead, "Then is it sin / To rush into the secret house of death / Ere death dare come to us?" John Donne wrote the first English defense of suicide, Biathanatos, in 1608, but had second thoughts (as well as a job, Dean of St. Paul's, that required staying on good terms with the church) and found it expedient to wait until after his death to have it published, in 1644. Other justifications of suicide followed. In the eighteenth century, the Age of Reason, traditional beliefs were reexamined from a rational, empirical, and skeptical perspective. Theological arguments against suicide were challenged, suicide was claimed to be a 12

Suicide and Attempted Suicide • 19 human right, and the subject became a secular matter as much as a religious one. Of course, the traditional views had many defenders. For example, the renowned religious leader John Wesley (1703-1791) said, with dubious logic, that failed suicides should be hanged. Similarly, the eminent legal authority William Blackstone (1723-1780) asserted that suicide was a crime against both G o d and king. A n d the illustrious philosopher Immanuel Kant, whose writings remain unsurpassed in incomprehensibility, used suicide as an example of moral error that could be demonstrated with his logical rapier, the categorical imperative. 13

During this time, the brutal treatment of suicidal people eased in some parts of Europe. For example, the laws against suicide were relaxed in France at the time of the French Revolution; and the Prussian penal code of 1794 (influenced earlier by the "liberal" monarch, Frederick the Great, and then by the French Revolution) did not punish attempted suicide. In England, however, trying to kill oneself remained a felony until 1961 (and was only decriminalized to encourage people to seek treatment), and anyone aiding, abetting, or counseling a suicide or attempted suicide is still subject to fourteen years imprisonment. 14

The Romantics of the late eighteenth and early nineteenth centuries (Byron, Keats, and Shelley in England; Lermontov in Russia; Chateaubriand and Lamartine in France; Novalis and Goethe in Germany ) went further, and glorified suicide as the heroic last act of a free man. Thus, from antiquity into the nineteenth century, suicide was mosdy a philosophical, ethical, religious, and legal issue; the concern was under what circumstances might it be forbidden, acceptable, or even desirable? Starting in the early 1800s, it gradually became a sociological/statistical inquiry as well as a psychological one: Who killed themselves and why they did so. The focus changed from philosophy and theology to the social conditions and personality traits associated with suicide. 8

h

More recently, with the advent of antipsychosis drugs, such as Thorazine in the 1950s, the concept of a biochemical basis for behavior has become i n creasingly persuasive. One of the effects of these changes has been to largely remove suicide from the category of moral crime. Instead, the fault has been

20 • Geo Stone shifted onto society, mental illness, or biochemical imbalance, things for which an individual can hardly be blamed. Thus, if suicide is involuntary and beyond an individual's control, rational or moral arguments against it will be useless. The only moral question, then, will be that of intervention, abstention, or assistance by concerned individuals or by society at large. While today most people still consider suicide an abnormal, destructive behavior" that should be prevented (except, perhaps, in the case of the terminally ill), its failure is no longer punished—or should one say rewarded?— by death. A n d so we progress. 1

H o w e v e r , this argument can be t u r n e d a r o u n d not only to p e r m i t suicide (e.g., Samson pulling d o w n the pillars, presumably after an okay f r o m G o d ["And w h e n Samson destroyed himself, with his enemies, by the demolition of the building, this can only be e x c u s e d on the g r o u n d that the Spirit, which p e r f o r m e d miracles through him, secretly o r d e r e d him to do so."

3 THREE WAYS TO STUDY SUICIDE

3

Sociology, psychiatry, and biology offer three different lenses currently used to study suicide as a pathology.

SOCIOLOGY

The sociological perspective looks at society's influence on its members; how do various social conditions (and their changes) affect suicide rates. E x amples of such social variables are income, unemployment rate, birth order, gun ownership, divorce, and immigration. As its most eminent early proponent, Emile Durkheim, said, "social facts must be studied as things, as realities external to the individual." 1

The sociological/statistical study of suicide actually began in the 1820s with research by Jean-Pierre Falret in France, and Johann Casper in Germany. Durkheim organized the earlier work and integrated it into a theoretical framework in the late 1800s. His groundbreaking book Suicide: A Study in Sociology was published in 1897. Durkheim felt that the Industrial Revolution had massively disrupted Western communities. As a result, people who didn't have the structure of ties to family or religion became particularly susceptible to suicidal urges. He called suicide due to such social disintegration "anomic." In other societies the individual is so highly integrated into the community that his life and behavior are tightly governed by the community's cus22

Suicide and Attempted Suicide • 23 toms. In these circumstances, most suicide occurs because it is expected—almost required—rather than from personal sorrow or guilt. Examples of such "altruistic" suicide include the Indian custom of suttee where widows (but not widowers) burn themselves to death; Japanese seppuku or hara-kiri where ritual disembowelment (sometimes followed by coup-de-grace decapitation) prevents, or atones for, dishonor. Among military officers in nineteenth-century Europe, suicide-by-pistol was the expected response to an inability to pay gambling debts. Suicide by groups seeing themselves as persecuted also falls into this category; the Branch D a vidians (Waco, Texas, 1993) for example, or the members of the People's Temple at Jonestown (Guyana, 1978), who held suicide "rehearsals." 2

Durkheim's third category, "egoistic" suicide, describes individuals who lack involvement with their reasonably stable societies. Such people are often misfits or criminals. A prototypic example might be an unemployed, isolated, man or woman living alone in a rooming house. Sociology's forte is the statistics of suicide. Its self-acknowledged limitation is that it doesn't tell us anything about why one person kills himself while another person, in similar circumstances, doesn't. Nor does it offer any good explanation of cultural and national differences. For example, if, as frequently claimed, Catholic countries have lower suicide rates than Protestant ones because Catholicism is the more cohesive religion, why does Catholic Hungary usually have the highest suicide rate in Europe, and, often, in the world? The suicide rate in Hungary, for various age groups is anywhere between five and twenty-five times the corresponding rate in nearby Greece. A n d , the suicide rate of countries bordering Hungary is highest in the regions near Hungary and in those with large Hungarian populations. 153

Sometimes there are extraordinary or temporary circumstances that lead to a high suicide rate. In the mid to late 1990s Sri Lanka, in the midst of a protracted civil war, has had unusually high rates. However, Greenland (127 per 100,000 population in 1987) has the highest rate in the world. This has been attributed to the cultural and social disintegration of the native Inuit population in the face of well-meaning Danish paternalism. 4

24 • Geo Stone

PSYCHOLOGY AND PSYCHIATRY The psychological/psychiatric approach rose to prominence a bit later than the sociological one, at the end of the nineteenth and beginning of the twentieth centuries. It emphasizes and examines the individual, and the conflicts within a particular mind that may lead to self-destructive behavior. " W h e n we learn that the most densely populated parts of the world have the highest incidence of suicide, and that suicides cluster in certain months of the year; do we thereby learn a single adequate, explanatory motive?" asked psychoanalyst Alfred Adler in 1910. " N o , we learn only that the phenomenon of suicide is also subject to the laws of great numbers, and that it is related to other social phenomena. Suicide can be understood only individually, even if it has social preconditions and social consequences." 5

While people with diagnoses of depression, schizophrenia, or psychosis have suicide rates five to fifteen times that of the general population, the vast majority of those who are so diagnosed do not attempt suicide. One limitation of the psychological strategy is the inability of experts to reliably predict who will carry out suicides and suicide attempts, even among the highest-risk groups. Robert Litman . . . believes that suicide-vulnerable individuals move in and out of periods of suicidal risk—sometimes for brief periods, sometimes for moderate or long periods—as their life circumstances fluctuate. But of all those people who enter that zone, very few actually kill themselves."For every hundred people at high risk," he says, "only three or four will actually commit suicide over the next couple of years.... It's like a slot machine.... You can win a million dollars on a slot machine in Las Vegas, but to do that, six sevens have to line up on your machine.That happens only once in a million times. In a sense it's the same with suicide". T h o s e spinning sevens represent all the biological, sociological, psychological, and existential variables that are associated with suicide—broken

Suicide and Attempted Suicide • 25 family, locus of control, decreased serotonin [a chemical found in the brain], triggering event, and so on. "In order to commit suicide, a lot of things have to fall together at once, and a lot of other things have to not happen at once," says Litman. "There's a certain random element determining the specific time of any suicide and, often, whether it happens or not.... It's as if you need to have six strikes against you ... and we're all walking around with one or two or three strikes. Then you have a big crisis and you have four strikes. But to get all six really takes some bad luck." 6

Hopelessness about the future seems to be a better predictor for suicide than is depression. For example, in one group of 207 suicidal patients, 89 were ranked high on a widely used "hopelessness" scale. Thirteen of fourteen suicides within the next five years came from this subgroup, even though only half of them had a diagnosis of depression. Nevertheless 76 of these 89 did not kill themselves, underscoring the difficulty in predicting suicidal behavior, even the highest-risk groups. Indeed, in one study a computer program was better at identifying people who would attempt suicide than was a group of experienced clinicians. To add insult to injury, half of the patients preferred "talking" with the computer to talking with the human interviewers. Another issue is that there is dispute as to what extent, if any, various schools of psychological therapy are effective. For example, in one study psychotherapy was found to be counterproductive with those who had attempted suicide. ° Other studies have been equivocal. Current expert opinion seems to be that psychotherapy is about as effective as drug therapy for mild to moderate depression, but significantly less so for more severe cases. 7

BIOLOGY The biological view sees physical disorders, often a biochemical imbalance, as the cause of suicide and other psycho-pathological problems, like schizophrenia. This concept was articulated by E m i l Kraepelin, a German contemporary of Freud's. The biological view didn't gain wide acceptance for a half century, largely because the biochemical tools for testing it were lacking.

26 • Geo Stone In suicide, the biochemical problem often seems to be associated with a low level in the brain of the chemical nerve-impulse transmitter serotonin. Treatment consists of repairing or overcoming the original neurochemical imbalance. Some drugs increase serotonin levels and are used as antidepressants with moderate, but increasing, effectiveness. Some evidence for, and limitations of, the biological model are: 1. Studies on twins provide the most persuasive evidence of a biological basis for suicide. In two investigations of suicide among twins, the identical twin of a suicide also killed himself in 19 percent of the cases (22 out of 118), while there were no instances (0 out of254) where the fraternal (nonidentical) twin of a suicide had done so. 12

2. Suicide tends to run in biological families. Adoption data show a significantly greater frequency of suicide among the biological relatives of suicides than among adoptive relatives. In a study of Danish adoptees diagnosed with depression, there were 15 suicides among 387 biologic relatives while only one suicide occurred in 180 adoptive relatives. Similarly, there were 12 suicides among 269 blood relatives of 57 adoptees who had killed themselves; there were no suicides among their 150 adoptive relatives. This is not to say that there is a suicide gene. But there are statistical associations between depression, aggression, and suicide, and depression clearly has a genetic component: For example, in 57 percent of identical twins studied, if one twin had major depression, so did the other. This evidence for a biological tendency to suicide is convincing. Yet even among identical twins, in more than four out of five instances the suicide of one twin was not followed by the suicide of the other. Tendency is not fate. 3. Studies on brain tissue and cerebro-spinal fluid (CSF) show that many people who kill themselves, especially those who use violent methods, have low levels of a brain tissue chemical neurotransmitter, serotonin, and its metabolic breakdown product, 5-hydroxyindoleacetic acid ( 5 - H I A A ) . "Lower levels of 5 - H I A A in C S F have been found to predict a 10-20 times higher mortality from suicide within 1 year after discharge from the hospital." Especially interesting is the fact that whether the psychiatric diagnosis was depression, alcoholism, schizophrenia, or personality disorder, low 13

14

15

Suicide and Attempted Suicide • 27 5 - H I A A was associated with significantly more of the suicides and suicide attempts, as well as other violent or impulsive behavior. In this model, lower C N S serotonin levels make people more aggressive and impulsive, and thus increase the effects of stress, depression, and psychosis. Moreover, the types of antidepressant drugs that increase serotonin levels are generally more effective in decreasing both suicidal thoughts and suicide attempts, than are other antidepressants that work by different mechanisms. 16

There are also animal data that link aggression with low serotonin levels. For instance, blocking the formation of serotonin causes tame housecats to become ferocious, and nursing rats to bite their pups to death. The 5 - H I A A hypothesis is not universally accepted. There are methodological criticisms. Some studies have failed to find any connection between suicide and 5 - H I A A , and most have found little or no correlation of 5 - H I A A levels with nonviolent suicide. This murky picture should not be entirely surprising, since "suicide" lumps together groups as diverse as depressed teenagers, prisoners, alcoholic adults, political protesters, and the terminally i l l . Most suicide is probably due to the interaction of multiple factors. Even if 5 - H I A A is one of them, it may be overcome or augmented by others. Finally, it's not clear that even if there is a relationship between low 5 - H I A A and suicide, violence, or impulsiveness, whether the low 5H I A A level is a cause of the behaviors, an effect of the behaviors, or is the result of some other yet-undiscovered factor. 17

18

One supposed problem with the serotonin model is that there are a number of countries, like Denmark, Switzerland, and Japan, with low rates of outwardly directed violence (for example, homicide) but with high rates of suicide. A possible explanation for this is that there are cultural factors that influence whether violent impulses manifest themselves as suicide or homicide. An alternative view, that suicide is associated with prosperity, is discussed later. A more significant weakness of the biological model as the prime mover in suicide is its difficulty in explaining the sometimes-large changes in suicide rates seen over short periods of time. For example, from 1958 to 1978 the suicide rate for Americans fifteen to twenty-four years old went from about 4 per 100,00 to about 14 per 100,000, an increase of roughly 250 per-

28 • Geo Stone cent. The suicide rate in Norway was an almost constant 7 per 100,000 from 1876, when central records were first collected, until about 1966. It then increased 112 percent (from 7.3 to 15.5 per 100,00 between 1960-64 and 1990), while that of England decreased by 36 percent (11.7 to 7.5 per 100,000 between 1960-64 and 1991) and Ireland increased 170 percent (from 2.7 to 7.4 per 100,000 between 1971 and 1988). A convincing biological explanation has not been found. 19

An interestingly different perspective is provided by some evolutionary b i ologists, who note the persistence of suicide (about 1 percent of all deaths) across culture and time. While such behavior may seem counterproductive in a simple Darwinian sense—if you're dead, you probably won't be passing on too many more genes—they argue that this may represent (like altruism), a trait that has evolutionary benefits. They suggest that suicide may be the sometimes-inappropriate expression of an instinct for self-sacrifice for the good of surviving relatives, who do pass on the deceased's genes. We see other forms of this in, say, parents perishing to save their children from danger, or old people killing themselves to leave more resources for their families. Consistent with this, psychiatrists have noted that many people who are considering suicide think of it in altruistic terms, as the best thing for their family and friends. "If you talk to people immediately after they [have] made a serious suicide attempt, they'll have a very altruistic explanation for what they did," says Dr. David C. Clark. "They believed it was the wise, clever and thoughtful thing to do." 20

An alternate view is that the tendency for depression, rather than suicide, is the behavior selected for. In this picture, depression is useful because it forces people to contemplate and, presumably, learn from their mistakes. Suicide is, in this model, due to an excess of that process. Unfortunately (for the model), most patients with major depression never attempt suicide, and suicide rates for people with other diagnoses (for example, schizophrenia or substance abuse) are comparable to those with major depression. Other researchers claim that traumatic or premature births are highly correlated with later suicide and even with the suicide method employed. There is both human and other animal evidence for each of these views, but they are no more convincing than other explanations. 21

Suicide and Attempted Suicide • 29 While it simplifies the picture, it may be counterproductive to limit one's understanding of suicide to biology, sociology, or psychiatry. There have been attempts to integrate some of these ideas under the label "suicidology." For example, Jack Douglas, in The Social Meanings of Suicide, argues that how the individual sees and interprets sociological situations determines their effects on her; a biologist might tack on a biochemically caused tendency toward impulsivity or violence. But, for the most part, we're still in the same position as the apocryphal blind men each describing a different part of an elephant: Each discipline tends to see suicide through its own filters and biases, and there is, as yet, no adequate synthesis.

4 WHY PEOPLE ATTEMPT SUICIDE

Let them think what they liked, but I didn't mean to drown myself. I meant to swim till I sank—but that's not the same thing. —Joseph Conrad In a real dark night of the soul it is always three o'clock in the morning. — F . Scott Fitzgerald To be or not to be: that is the question. —William Shakespeare Thousands of books have attempted to answer the question of why people kill themselves. To summarize their findings in three words: to stop pain. Sometimes this pain is physical, as in chronic or terminal illness; more often it is emotional, caused by a myriad of problems. In any case, suicide is not a random or senseless act, but an effective, if extreme, solution. A slightly more elaborate list of some reasons people commit or attempt suicide follows. The categories are arbitrary and overlap to some degree. However, this is just an outline, and there is no lack of books that discuss suicidal motivation in much more detail and from many different perspectives.

30

Suicide and Attempted Suicide • 31 1. Altruistic/heroic suicide. This is where someone (more-or-less) voluntarily dies for the good of the group. Examples include the Greeks at Thermopolae; the Japanese kamikaze pilots at the end of W W I I ; the Buddhist monks and others who, starting in 1963, burned themselves to death trying to stop the Vietnam War; elderly Inuit (Eskimos) killing themselves to leave more food for their families; some Communists who confessed to invented (and often impossible) crimes during the Purge Trials of the late 1930s and early 1950s. Gandhi's tactic of hunger strikes, called satyagraha or "soul force," would have fallen into this category, had the British authorities failed to respond to his demands. 1

2. Philosophical suicide. Various philosophical schools, such as stoics and existentialists, have advocated suicide under some circumstances. 3. Religious suicide. There is a long history of religious suicide, usually in the form of martyrdom. This was widespread in the early years of Christianity and was also commonly seen in the various heresies uprooted before and during the Reformation, Counter-Reformation, and Inquisition. More recent examples may include members of the Solar Temple in Switzerland, France, and Canada; the San Diego Hale-Boppers in March 1997; the Branch Davidians in Waco, Texas; and some of the people at Jonestown, Guyana. 1

4. Escape from an unbearable situation. This may be persecution, a terminal illness, or chronic misery. There is no lack of historical examples: E p i demics of suicide were frequent among Jews in medieval Europe (sometimes they were given a choice between converting to Christianity and death). Later, both Indian and black slaves in the New World committed mass suicide to escape brutal treatment. One slave owner supposedly stopped such desertion among his slaves by threatening to kill himself and follow them into the next world, and impose worse repression there. There were large numbers of suicides during times of pestilence in medieval Europe. More recently, A I D S has generated a similar response among many of its victims. There was also a wave of suicides among priests and their wives around 1075, after Pope Gregory V I I imposed celibacy on the clergy, who had previously been allowed to marry. M a r riage had been only slightly more popular than damnation with the church d

32 • Geo Stone ("It is better to marry than to burn"), but had been accepted for its first thousand years. A significant number of killers commit suicide. Four percent of 621 consecutive murderers later killed themselves; and about 1.5 percent of suicides follow murders. A l l of these situations can be readily seen as more or less unbearable. However, sometimes "unbearable" means failing an exam or missing a free throw in the big game. As George Colt notes, 4

Most adolescent depression is caused by a reaction to an event—a poor grade, the loss of a relationship—rather than a biochemical imbalance.... Feeling blue after not getting into one's firstchoice college is as appropriate as feeling happy after scoring a winning touchdown. But many adolescents who experience depression for the first time don't realize that it won't last forever. 6

Or, as an anonymous teenager said, "It sounds crazy, but I think it's true— kids end up committing suicide to get out of taking their finals." 5. Excess alcohol and other drug use. The observed high correspondence between alcohol and suicide can be explained in several ways, including: (a) Alcoholism can cause loss of friends, family, and job, leading to social isolation. However, this may be a chicken-and-egg question; it's equally plausible that family or job problems induce the excess alcohol use. In its later stages, the fact and consequences of alcoholism dominate the picture and are often blamed for everything; (b) alcohol and suicide may both be attempts to deal with depression and misery; (c) alcohol will increase the effects of other sedative drugs, frequently used in suicide attempts; (d) alcohol may increase impulsive actions. 7

68

The significance of the last two points is emphasized by findings that alcoholic suicide attempters who used highly lethal methods scored relatively low on suicidal-intent tests. The correlation between lethal intent and method was found only among nonalcoholics. Thus, to claim that alcoholism causes suicide is simplistic; while the association of alcohol abuse with suicide is clear, a causal relationship is not. Both alcoholism and suicide may be responses to the same pain. "A man 9

Suicide and Attempted Suicide • 33 may drown his sorrows in alcohol for years before he decides to drown himself." 6. Romantic suicide. " M y life is not worth living without him." This sentiment is most celebrated among the young, as in Romeo and Juliet, but is probably most frequent among people who have lived together for many years, when one of them dies. 10

Suicide pacts (dual suicide) constitute about 1 percent of suicides in Western Europe. Most often, participants are more than fifty-one years old— except in Japan, where 75 percent of dual suicides are "lovers' pacts." 7. "Anniversary" suicide. This is characterized by use of the same method or date as a dead loved one, usually a family member. "Imitative" suicide is similar to anniversary suicide in its focus on the dead, but uses a different date and method. 8. "Contagion"suicide. This is where one suicide seems to be the trigger for others, and includes cluster and copycat suicides, most often among adolescents. For example, on A p r i l 8, 1986, Yukiko Okada, eighteen, jumped to her death from the seventh floor of her recording studio. She had recently received an award as Japan's best new singer. Media attention was intense. Thirty-three young people, one nine years old, killed themselves over the next sixteen days, twenty-one of them by jumping from buildings. There are comparable examples from many parts of the world. The highly publicized suicide of a Hungarian beauty queen was followed by an epidemic of suicides by young women who used the same method. Similarly, there was a spate of ethylene glycol (automobile antifreeze) intentional poisonings in Sweden following two accidental fatalities and "spectacular attention in the Swedish mass media." In the United States there have been clusters of suicides, most often (or most often reported) among high school students, but not necessarily using identical methods. Even fictional accounts may be enough, as in a claimed spurt of Russian roulette deaths shortly after the release of the film The Deer Hunter, with its powerful and nihilistic Russian roulette scene. On the other hand, other studies found no linkage between most newspaper reports and suicides. Nor do copycat suicides occur consistently. For example, the 1994 death of Nirvana lead singer Kurt Cobain was not followed by a cluster of suicides. In the seven weeks following his death there 11

34 • Geo Stone were twenty-four other suicides in the Seattle area, compared with thirtyone in the corresponding weeks of the previous year. 9. An attempt to manipulate others. "If you don't do what I want, I'll kill myself," is the basic theme here. However, the word "manipulative" does not "imply that a suicide attempt is not serious. . . . Fatal suicide attempts are often made by people who are hoping to influence or manipulate the feelings of other people even though they will not be around to witness the success or failure of their efforts." Nevertheless, while people sometimes die or are maimed from their attempts, the intention in this case is to generate guilt in the other person, and the practitioner generally intends a nonfatal result. 22

10. Seek help or send a distress signal. This is similar to "manipulative" suicide except that there may be no specific thing being explicitly sought; it's the expression of an unbearable burden of pain and misery. This may occur at any age, but it is more frequent in the young. However, "Parents may minimize or deny the attempt. One study found that only 38 percent of treatment referrals after an adolescent attempt were acted on. Another found only 41 percent of families came for further therapy following an initial session. 'It's often difficult to get parents to acknowledge the problem because they are the problem,' says Peter Saltzman, a child psychiatrist." 11. "Magical thinking" and punishment. This is associated with a feeling of power and complete control. It's a "You'll be sorry when I'm dead" fantasy. An illustration is the old Japanese custom of killing oneself on the doorstep of someone who has caused insult or humiliation. This is similar to "manipulative" suicide, but a fatal result is intended. It's sometimes called "aggressive" suicide. In a power struggle, if you can't win you can at least get in the last word by killing yourself. 23

12. Cultural approval. Japanese (like Roman) society has traditionally accepted or encouraged suicide where matters of honor were concerned. Thus, the president of a Japanese company whose food product had accidentally poisoned some people killed himself as an acknowledgment of responsibility for his company's mistake. It's almost unheard-of to find an American C E O who has voluntarily resigned on account of his company's misdeeds, let alone one who has committed suicide because of them. In Japan, 275 company directors killed themselves in a single year, 1986 (albeit for a variety of reasons). 24

Suicide and Attempted Suicide • 35 13. Lack of an outside source to blame for one's misery. Andrew Henry and James Short present evidence that when there is an external cause of one's unhappiness, the extreme response is rage and homicide; in the absence of an external source, the extreme response tends to be depression and suicide. Thus, while marriage and children are associated with a lower suicide rate, they are also correlated with a higher homicide rate. 25

Henry and Short also suggest that, as economic quality-of-life improves, homicide should decrease and suicide increase. Longtime suicide researcher David Lester found such a correlation when comparing forty-three countries, and also when comparing American states. 26

27

However, national data are contradictory: It's easy to find countries with low suicide and low homicide rates (for example, Great Britain and Greece); or high rates of both (for example, Finland and Hungary). Furthermore, recent multinational increases in suicide rates are roughly matched by similar increases in homicide. In addition, there are high rates of both suicide and homicide in prison. Most jail (short-term) and prison (longer-term) suicide rates have been reported between 50 and 200 per 100,000 per year, while the age-matched male rate in the general population was around 25. Jail suicide is more frequent than prison suicide. Still, Henry and Short's hypothesis can be used to explain some counterintuitive facts, such as the low suicide rate among Nazi concentration camp inmates, among African Americans, and during wartime; though, as Erwin Stengel observed, "It is a melancholy thought that marriage and the family should be such effective substitutes for conditions of war. 28

14. Other. Most suicides have multiple causes. Consider, for example, an existentialist with a serious illness who is devastated by a recent divorce and consequently suffering from "clinical major depression." He has a prescription for antidepressant medication which makes him feel well enough to go out of the house. He goes to a bar, gets drunk, comes back, and shoots himself with a loaded gun he kept in the bedroom. None of his neighbors responds to the noise and he bleeds to death. What "caused" his death: physical illness, philosophy, divorce, depression, medication, alcohol, availability of a gun, or social isolation? Or, perhaps, none of the above: From a

36 • Geo Stone slightly different perspective, none of these factors caused the suicide; rather it is the pain associated with them (along with the unwillingness to bear it) that precipitates suicide. 32

"Reasons" cited for suicide change with the times. Dr. Forbes Winslow wrote in 1840 that the increase in suicide was due to socialism, and particularly, Tom Paine's Age of Reason. Additional causes he cited were "atmospheric moisture" and masturbation, "a certain secret vice which, we are afraid, is practised to an enormous extent in our public schools." He recommended cold showers and laxatives. 33

THE QUESTION OF INTENT IN SUICIDE ATTEMPTS The survivor of a suicide attempt act is regarded by the public as either having bungled his suicide or not being sincere in his suicide attempt intention. He is looked upon with sympathy mixed with slight contempt, as unsuccessful in an heroic undertaking. It is taken for granted that the sole aim of the genuine attempt is self-destruction, and therefore the dead are successful and the survivors unsuccessful. —Erwin Stengel 34

People who carry out acts lumped together as "suicide attempts" actually have a variety of motives, and combining various intents masks important differences. According to Louis Dublin, a respected statistician, almost a third fully intend to kill themselves; fewer than half of these succeed. Those who fail generally do so because of unexpected rescue, or, more often, mistakes in planning or knowledge. These people tend to use generally lethal methods (guns, hanging, drowning, jumping) and are disproportionately older and male. Another third clearly do not want to die. Their suicide attempt, more aptly called a "suicidal gesture," is a cry for help or attention. They're trying to change their circumstances or to influence important people in their lives, usually parents or a spouse or lover. They make every effort to be saved, often scheduling the attempt to coincide with the expected return of a designated rescuer. 35

Of course, rescuers are sometimes delayed—or uninterested. Forensic texts

Suicide and Attempted Suicide • 37 provide some charming examples. In one case a woman took an overdose of barbiturates and pinned a note to herself saying, "If you love me, wake me up." Her husband came home around 10 P . M . , saw the note, tossed it into the trash, and went out to a bar. When he returned early next morning, she was dead. The official cause of death was suicide. Criminal charges of homicide were considered, but not filed. 36

These suicide "attempters" are more likely to be younger and female, and use less lethal means than the first group, most frequently drug overdoses and wrist cutting. Note that a "failed" suicide attempt in this group is one in which the person dies, which is the opposite of failure in the previous group. The last third are people tossing the dice. They are in such emotional pain, rage, or frustration that they don't much care if they live or die, as long as the pain stops. They tend to be impulsive, not plan carefully (if at all), and leave their survival to chance. In another study, of 500 suicide attempts, only 4 percent were described as "well-planned," but only 7 percent turned out to be more or less harmless. 37

38

The relationship between the seriousness of someone's intent to kill herself and the lethality of the attempt is controversial. While it would seem i n tuitively plausible that the more seriously one intended to die the more lethal the resulting suicide attempt would be, numerous studies have reached contradictory conclusions: Some have found an association, others have not. The debate is more than academic. If the connection between serious intent and lethality of attempt is real, it implies that suicide prevention strategies that focus on decreasing the availability of lethal methods (for example, gun-control laws) will fail, because people wanting to die will simply switch to other, similarly lethal methods, such as hanging. If, on the other hand, there is no good correlation between intent and lethality, then a decrease in the availability of lethal methods will be effective in decreasing suicides, because serious (but not fully rational) attempters will tend to switch to methods of lesser lethality. 39

Other evidence suggests a third possibility, that impulsivity or depression might have the best correlation with use of lethal methods; and that these in turn, are associated with neurochemical imbalance. A n d we find ourselves back to the biological issues raised in chapter 3. 40

YOUTH SUICIDE

I want to kill myself, but I don't want to be dead. — a fifteen-year-old Most things, except agriculture, can wait. —Jawaharlal Nehru Teenagers attempt suicide roughly ten times more frequently than adults, although their fatality rate of 11.1 per 100,000 people is about the same as adults'. Suicide is the third leading cause of death among fifteen- to nineteenyear-olds. For this age group, there were 5,174 motor-vehicle deaths in 1994, compared to 1,948 suicides. According to U.S. national data released in September 1991, about 1 million teens (out of about 25 million) attempt suicide each year, of which an estimated 276,000 sustain injuries serious enough to require medical treatment. Some other estimates (these are total, not per-year) are considerably higher: 3 percent of elementary school, 11 percent of high school, and 17 percent of college students. However, "most were low-lethality attempts for which medical or other attention was not sought. Accordingly, the vast majority of [these] suicide attempts will not be uncovered by investigations dealing solely with clinical or medically identified populations." Thus, estimates or calculations of teenage suicide-attempt rates are particularly unreliable. 1

39

40 • Geo Stone About four times more girls than boys make suicide attempts, but boys are much more likely to die: About 11 percent of (reported) males' attempts were fatal, compared to 0.1 percent of females', a ratio of more than 100:1. This also yields a ballpark average of about fifty attempts for every fatality in this age group. 3

This low fatality rate might be taken to mean that most of these adolescents don't want to kill themselves (true) and that there is generally one or more "warning" attempt before a lethal one (not true). In a study from F i n land, only 30 percent of male, and 68 percent of female suicides thirteen to twenty-two years old had made a previous (known) suicide bid. This suggests that many of these lethal first-attempters intended to die. 4

Compared to those of older people, adolescents' suicide-attempt statistics show two significant differences. First, the fatality rate for boys is a hundred times that of girls, a much greater gender difference than with any other age group. The immediate reason is clear enough: Most teenage girls use relatively low-lethality methods like drugs and wrist cuts, while a substantial number of boys use guns and hanging. The reasons behind these choices are not known. Second, the fatality rate among adolescents, less than 2 percent, is much lower than that among the elderly, variously reported to be between 25 and 50 percent. This may be because the young, however miserable, usually have more reason for optimism about the future than do the old, who are too often without friends, family, job, and health. Nevertheless, the adolescent suicide rate is increasing and approaching the national average. U.S. suicide rates for fifteen- to nineteen-year-olds and those over sixty-five are shown in Table 5.1.

This corresponds to about two thousand suicides among fifteen- to nineteenyear-olds per year. While it's true that the suicide rate is substantially higher among old people, suicide is a relatively more frequent cause of death in the young, who have few deaths from illness. That's why it's the third leading cause of death among fifteen- to twenty-four year-olds, but ranks ninth or tenth for those fifty-five to seventy-four. These numbers show that overall U.S. suicide rates have been essentially unchanged between 1980-94.

Crosby. According to Crosby, in 1992 firearm-related deaths accounted for 64.9 percent of suicides among people under twenty-five. Among those aged fifteen through nineteen, firearm-related suicides accounted for 81 percent of the increase in the overall rate from 1980 to 1992. 9

INTERNATIONAL DATA a

Data from around the world show no consistent suicide pattern. Twenty of twenty-seven national rates rose between 1970 and 1980; so did twentytwo of twenty-seven youth rates. The male youth-suicide rate generally increased more than the female rate. In most countries, the youth suicide rate is around one half of the adult rate, but in Chile, Venezuela, and Thailand, the youth rate is somewhat higher than the overall adult rates. The reasons are uncertain; and youth suicide rates show fewer correlations with social variables, such as income or national birth rate, than do adult rates. 10

In terms of methods, a sixteen-country survey found rates from 1960 to 1980 increased for suicide by motor-vehicle exhaust (carbon monoxide), guns, and hanging; decreased for domestic gas; and were stable for solid and liquid poisons, drowning, and cuts/stabs. 11

ADOLESCENT MISERY

Suicidal adolescents are so caught up in their own misery, that they can't see they have choices. Most have had little experience dealing with problems. They often can't or won't talk with their parents and may have no other trusted adults in their lives. Frequently they have withdrawn from their friends. This isolation further decreases their contact with other ideas and views. Death may seem like the only solution to teenagers grieving over a major loss in their lives. In the bleak words of one fourteen-year-old girl, "If I died, I wouldn't hurt as much as I do now." "But if you could say to them, 'Don't commit suicide because I can get you

Suicide and Attempted Suicide • 43 away from the pain without dying,'" says psychiatrist Michael Peck, "they'd likely be ready to do it." 12

One counselor's description of a session with a suicidal college student follows: The student was highly religious, single, and pregnant. Overcome by guilt, she wanted to kill herself. The counselor tried to show her that there were other possible solutions: I did several things. For one, I took out a single sheet of paper and began to "widen her blinders." O u r conversation went something on these general lines: " N o w , let's see: You could have an abortion here locally." ("I couldn't do that")... ."You could go away and have an abortion." ("I couldn't do that") "You could bring the baby to term and keep the baby." ("I couldn't do that") "You could have the baby and adopt it out." ("I couldn't do that") " W e could get in touch with the young man involved." ("I couldn't do that") " W e could involve the help of your parents." ("I couldn't do that") "You can always commit suicide, but there is obviously no need to do that today." ( N o response.) " N o w , let's look at this list and rank them in order of your preference, keeping in mind that none of them is perfect." The very making of this list, my nonhortatory and nonjudgmental approach, had already had a calming influence on her. Within a few minutes her lethality had begun to de-escalate. She actually ranked the list commenting negatively on each item. What was of critical importance was that suicide was now no longer first or second. We were then simply "haggling" about life—a perfectly viable solution. 13

Sometimes the triggering event is astonishingly trivial: George Colt mentions, the fourteen-year-old boy who, according to his parents, shot himself because he was upset about getting braces for his teeth that afternoon; the girl who killed herself moments after her father refused to let her watch "Camelot" on television.... Such incidents are often misinterpreted as the "reason" for a suicide, but they are usually the culmination of a long series of difficulties. 14

44 • Geo Stone Even so, there may be qualitative differences between suicidal adolescents and older people. "When young people are suicidal, they're not necessarily thinking about death being preferable, they're thinking about life being intolerable," says Sally Casper, former director of a suicide prevention agency in Lawrence, Massachusetts. "They're not thinking of where they're going, they're thinking of what they're escaping from. Recently, a fifteen-year-old girl came in here. In one pocket she had a bottle of sleeping pills, and in the other pocket she had a bottle of ipecac, a liquid that makes you vomit. She said, 'I want to kill myself, but I don't want to be dead. I mean, I want to be dead, but I don't want to be dead forever, I only want to be dead until my eighteenth birthday.'" 15

The fact that more than 95 percent of adolescents who live through their suicide attempt do not go on to kill themselves suggests that their problems are not as permanent or serious as their attempted solution. Feeling miserable and hopeless, these adolescents choose an irrevocable solution to temporary problems and, "reject not just a last few bitter moments, but life, all of it and at once, with all its myriad possibilities." This is what make youth suicide especially heartbreaking. 16

6 SUICIDE IN THE ELDERLY AND OTHER GROUPS

Lord save us all from old age and broken health and a hope tree that has lost the faculty of putting out blossoms. — M a r k Twain 1

W h e n an old person attempts suicide he almost fully intends to die. —American Psychiatric Association

STATISTICS The elderly (defined as those over sixty-five years old) have, historically and currently, the highest suicide rates in most—but certainly not all— countries of the world. The death rate in adolescent suicide attempts is roughly 2 percent; among men over 45 years old, R. W. Maris found 88 percent of first-time attempts are fatal. Other estimates are lower, but still on the order of 25 to 50 percent, though psychiatrist Herbert Hendin, questioning these numbers, points out that there seem to be many more elderly survivors of suicide attempts than there are suicide deaths in this age group. Despite recent decreases in old-age suicide frequency and increases in youth suicide, the suicide rate for the elderly in the United States is still more than 50 percent higher than that of fifteen- to twenty-four-year-olds. 2

45

46 • Geo Stone Twenty-six percent of the population is over fifty years old; 39 percent of suicides are from this group, a rate 1.5 times the national average. White males over fifty years old are about 10 percent of the population, but account for 33 percent of the suicides in the United States. Elderly white males have a suicide rate five times the national average. 4

5

Among people over sixty-five years old (12 percent of the population), the suicide rate was about 22 per 100,000 (21 percent of suicides) in 1986, or almost twice the national average. The actual rate for the elderly is probably a good deal higher, since, "many deaths from suicide are never investigated and are reported mistakenly as accidents or deaths from natural causes, particularly when the victim was old." The annual suicide rate for elderly women (6.7 in 100,000) is lower than that for middle-aged women (7.9 in 100,000), and about one-sixth that of elderly men (around 40 in 100,000); however, the rate for women is relatively underreported, since they tend to use methods (for example, overdose) that leave room for other verdicts. Since American men most often use guns, these deaths are harder to attribute to "natural" or other causes. Nevertheless, the fact that American male suicide rates peak in old age while female rates are at their maximum during middle age is difficult to explain. The unpleasant realities of old age—increasingly poor health, death of a husband or wife, relegation to a nursing home—fall more frequently on women than men, due to the former's greater longevity. On the other hand, women are generally better than men at maintaining social and family contacts. A n d men, due to the traditionally higher status and more competitive nature of their activities (for example, business, sports, war) lose more social standing to the infirmities of old age than do women, who have generally lower rank and thus less distance to fall. 6

Reasons for these high rates seem to include: 1. Social isolation and loneliness, especially among widowers. 2. Physical isolation: Because many old people live alone, a suicide attempt may not be discovered soon enough to survive it. 3. The accumulation of losses, such as of friends, physical and mental abilities, social status, and health. 4. The elderly use more lethal methods than do younger peopled

Suicide and Attempted Suicide • 47 5. O l d people are less likely to survive any given level of injury than are younger, healthier, ones. Some specific reasons were identified among elderly suicides from the M i a m i area. The single most-cited cause was "physical health concerns," which were more frequent than the next two reasons ("depression" and "unknown") combined. Such health concerns are not necessarily accurate. In one study of248 suicides, more people (eight) killed themselves in the mistaken belief that they had cancer than the number of suicides who, in fact, had terminal cancer. The real rates are probably a good deal higher than the official ones. This is because many drug overdoses have no witnesses, no wounds, and look like a natural death. Since serious preexisting illness is common in the elderly, such deaths are particularly likely to be misdiagnosed as "natural." In one study, 15,000 autopsies in apparently natural deaths were reviewed: 764 (5.1 percent) of the bodies contained enough poison to account for death. 9

10

About half of the elderly who commit suicide are "depressed," but depression is common among old people. Both psychiatric and physical illness are more common in elderly suicides than in younger ones, whose deaths are more often precipitated by relationship, school, job, or jail problems. Between 60 and 85 percent of elderly suicides had significant health problems and in four out of every five cases this was a contributing factor to their decision. On the other hand, nonsuicidal elderly had rates of physical illness similar to the suicidal. Does depression affect willingness to accept treatment for other medical problems? In one study, depressed patients were less inclined than nondepressed ones to want medical treatment when the likelihood for improvement in some physical disease was good, but there was no difference between the two groups when the prognosis was poor. It seems that both groups were equally realistic about a poor prognosis, but that the lower quality-of-life and hopes-for-the-future expectations among depressed patients decreased their willingness to seek or accept help even when the probability of improvement was good. 11

12

13

14

This is consistent with other data. For example, a survey of elderly (sixty

48 • Geo Stone to one hundred years old) visitors to senior centers in Indiana found that depression, low self-esteem, and loneliness were not associated with a decision to end their lives if faced with terminal, or debilitating chronic, illness. Again, both the depressed and nondepressed elderly were similarly pragmatic about their options under these circumstances.

15

However, when the severity of the depression is taken into account, differences appear. Elderly patients who were hospitalized for major depression were asked, before and after antidepressant medication, whether they wanted life-sustaining treatment for their current physical health problems and for two hypothetical physical illnesses. In the relatively mild to moderate cases, remission of their depression did not increase their willingness to accept medical intervention; however, in the most severely depressed people, it did. This suggests that people in the midst of severe depression should probably not make life-and-death decisions, because their views are likely to change after antidepressant treatment. 16

Poverty is not a good suicide predictor. Sweden and Denmark both have high per-capita income as well as comprehensive social welfare for the aged. They also both have high suicide rates among the elderly, as well as in the general population. Greece and Mexico, which have a far lower (economic) standard of living than Sweden and Denmark, have particularly low rates, though even these rates are higher in the elderly than in the general population. Interestingly, in the United States, during times of economic prosperity, the elderly suicide rate goes down while the suicide rate of younger adults goes up. A final observation: Suicide notes left by the elderly tend to show a desire to end their suffering, rather than dwelling on interpersonal relationships, introspection, or punishing themselves or others, which are common themes in younger suicides. 17

SUICIDE RATES AMONG VARIOUS GROUPS

Native Americans have the highest "racial" rate: 16.2 in 100,000 (199193, age-adjusted); while the rate for white Americans was 11.1 in 100,000 (1992, age-adjusted). Among Native Americans, the pattern of suicide re-

Suicide and Attempted Suicide • 49 sembles that of African Americans: a male peak in the early twenties and decreasing thereafter. This pattern differs from that of white Americans, where elderly white males have the highest rates. Black Americans have reported suicide rates substantially lower than those of whites—except among males twenty-four to thirty-five years old, whose rates are similar. The overall rate for African Americans (6.2 in 100,000 in 1980; 7.0 in 100,000 in 1994) is roughly half that of whites, a ratio which has been consistent over many years. There is, however, some evidence that a small part of the difference is due to African American suicides being more underreported than white suicides. The best single socioeconomic predictor appears to be religious affiliation. Suicide is infrequent in Moslem populations, typically reported as less than 1 in 100,000 per year. It also is uncommon in many Catholic countries, with rates of 2 to 8 per 100,000 per year. On the other hand, Catholic Austria and Hungary have rates of 23 and 39 per 100,000 per year, respectively. Protestant, Hindu, and Buddhist regions have, with a few exceptions, higher reported suicide rates than Moslem or Catholic ones. 19

20

However, there is substantial skepticism about the accuracy of suicide statistics, particularly from societies in which suicide is most condemned. Psychiatrist Erwin Stengel observes, "In Roman Catholic and Moslem countries a verdict of suicide is such a disgrace for the deceased and his family that it is to be avoided wherever possible." The suicide rate is not reliably correlated with such factors as income, education, and health-care availability. The effect of unemployment is in dispute. For example, while some studies have found an association between unemployment and suicide, in England there was a 35 percent decrease in the suicide rate between 1963 and 1975, the same period that showed a 50 percent increase in unemployment. While there is no good correlation with wealth or poverty and suicide, certain professions have especially high rates: psychiatrists, physicians, lawyers, and retired military officers. 21

However, (to list a few risk factors for suicide) the highest suicide likelihood would probably be found in depressed, i l l , elderly white Protestant

7 SOME FREQUENTLY ASKED QUESTIONS ABOUT SUICIDE

ARE SUICIDAL PEOPLE CRAZY?

3

Yes, no, not necessarily, and so what. Certainly, people with a diagnosis of schizophrenia have a high lifetime risk of suicide (10 percent) as do people with severe depression (15 percent) and/or alcoholism (2 to 11 percent). But so do people with medical illness: 18 to 85 percent—studies are all over the map—of suicides had a physical illness; for 11 to 69 percent this was an "important contributing cause"; however, only around 5 percent were terminally i l l . In addition, the association of suicide with mental illness or alcoholism does not mean that suicide cannot be rational: chronically depressed, alcoholic, or schizophrenic persons may decide that it is better to be dead than to continue living as they are. 1

A n d to insist that suicide is irrational and attribute it to depression or mental illness "is absurd and infuriating to those who have spent time at the bedside of dying patients who are suffering severely with no good choices." Besides, "who wouldn't be depressed with such severe limitations to a meaningful life as incontinence, inability to speak, heavy curtailment of the ability to move, and loss of dignity?" Moreover, one doesn't need to be terminally i l l to decide that one's physical, mental, or emotional limitations have become unacceptable, and that 5

52 • Geo Stone it's pointless to go on living. As an eighty-four-year-old woman said to her son, a professor of health policy: Let me put this in terms you should understand, David. My "quality of life"—isn't that what you call it?—has dropped below zero. I know there is nothing fatally wrong with me and that I could live on for many years. With a colostomy and some luck, I might even be able to recover a bit of my former lifestyle, for a while. But do we have to do that just because it is possible? Is the meaning of life defined by its duration? Or does life have a purpose so large that it doesn't have to be prolonged at any cost to preserve its meaning? I've lived a wonderful life, but it has to end sometime and this is the right time for me. My decision is not about whether I'm going to die—we will all die sooner or later. My decision is about when and how. I don't want to spoil the wonder of my life by dragging it out in years of decay. I want to go now, while the good memories are still fresh. Help me find a way. 7

Studies have claimed to find among suicides about three times the rate of mental disorders as among people with nonsuicidal natural deaths (77 percent versus 25 percent). Other studies have found similar, higher, and lower rates. However, some of these investigations have had the benefit of hindsight: "the highest estimate of mental illness when a sample had been diagnosed before suicide was 22 percent. Afterward the highest estimate was 90 percent." After-the-fact diagnosis is rightly criticized for lack of objectivity: W h e n a psychiatrist knows that someone died a suicide, his conclusion will be influenced by that knowledge, particularly if the psychiatrist believes that people who kill themselves must be crazy: 8

The diagnosis of mental illness is especially suspect when it comes to self-destruction. The argument connecting suicide and mental illness is tautologically based upon our cultural bias against suicide... . W e say, in essence,'All people who attempt suicide are mentally ill." If someone asks,"How do you know they are mentally

Suicide and Attempted Suicide • 53 ill?" the implied answer is, "Because only mentally ill persons would try to commit suicide."

15

But there is a wide range of opinion, even within the psychiatric community: Is every suicide mentally ill and in need of hospitalization as [interventionist] Eli Robins believes? ... Or is he simply called mentally ill for the purpose of controlling his behavior as [radical Thomas] Szasz believes? Or does he have the right to kill himself whether or not he is mentally ill as [libertarian Eliot] Slater advocates? These views reflect the diversity of psychiatric thought with regard to suicide. My own view is that each of these positions contains some truth and that no one of them is an adequate guide for social policy. Most suicide can be diagnosed under present clinical standards as mentally ill; many diagnoses are influenced by the concern with suicide and the desire to prevent it through hospitalization; and the diagnosis of mental illness is not only insufficient to explain suicide but does not by itself justify taking away an individual's rights [But] Surely confinement for a limited period for the purpose of evaluation with a view to providing help is indicated. 16

19

I would agree that it is better to err on the side of temporary intervention. People sometimes regret things they do; suicide is hard to regret. You can usually kill yourself later, but you can't bring yourself back to life. O n the other hand, it remains all too possible to turn "temporary" into permanent; to subject people to conditions that worsen their state; to drug them into submission or to lock them up indefinitely. There need to be clear limits to both the duration and nature of any intervention; and if someone is persistent in wanting to end their life, that, however distressing, must—and ultimately will—be their decision to make. You don't have to be "crazy" to commit suicide.You just have to bedesperate, and in need of attention and care. —Emilinda, age fifteen

20

54 • G e o Stone

The notion that suicidal people are crazy also tends to isolate those who are feeling suicidal. Because of the stigma associated with mental illness, they may not be willing to seek help, even in a crisis. Thus, one of the ironies of suicide is that a suicide attempt—if survived— is probably the most dramatic and convincing way to draw attention to a problem and get help. Often family, psychiatric, and social service resources become suddenly available. A survey of Swiss survivors found that a majority felt that their actions had positive consequences for them. In Erwin Stengel's words, "The suicidal attempt is a highly effective though hazardous way of influencing others and its effects are as a rule . . . lasting." Optimists may derive comfort from the fact that only about 1 percent of suicide survivors kill themselves within one year; of 886 suicide survivors in another study, only 3.84 percent killed themselves within five years. A Swedish study with a thirty-five-year follow-up found 10.9 percent of its subjects ultimately died by suicide. A pessimist might note that about half of the people who make a suicide attempt will make another one; the one-year suicide rate of 1 percent is 50 times the rate of nonattempters; and 10 to 15 percent will eventually kill themselves, a rate 10 to 15 times that of the general population. 21

How WOULD I KNOW IF SOMEONE CLOSE TO ME WAS CONSIDERING SUICIDE?

There are two general areas, which overlap to some degree, to look at: (1) sociological or biological risk factors and (2) individual signals. Risk factors are discussed in chapter 3 and elsewhere. The most familiar method of finding out if someone is contemplating suicide consists of being sensitive to various verbal and behavioral signs; but the fact is, while many people consider, mention, or threaten suicide, far fewer make a suicide attempt. Probably the closest we can get to knowing is to ask—usually not a comfortable question to think about, let alone ask. The most important suicide warning signs are: 1. A previous suicide attempt. Between 20 to 80 percent of suicides (studies vary wildly) have made one or more prior attempts. 28

Suicide and Attempted Suicide • 55 Whatever the actual number, this is the single most significant flag. 2. A major change in behavior or personality. A normally cheerful person may become quiet and withdrawn, and stop formerly pleasurable activities. Insomnia, or more often an excess of sleep, may be seen. Giving away prized possessions is sometimes a sign that a decision for suicide has been made. However, in all of these and other changes, alternative reasons for the behavior are entirely possible. 3. Reckless behavior. "I don't care" or "leave it to chance" actions are close to out-and-out suicidal behavior. An example of this is "Russian roulette." 4. Severe depression. Some of the components of depression are hopelessness, inability to concentrate, sleep disturbances, feelings of worthlessness, loneliness, and sadness. Such a person might say things like, "You would be better off without me," or "Everything I touch turns into ashes." However, some people are so depressed that they don't have the energy to kill themselves. These folks are actually at higher risk when they're just starting to feel a little better. As one suicidal woman noted, It takes a tremendous amount of energy to figure out how you're going to kill yourself.... I wanted something that was final and wasn't going to be messy. I didn't want to jump off the roof; I might end up only half dead, and I wouldn't like that. I didn't want to blow my head off—I didn't happen to feel that physical disembodiment would be a particularly pleasant thing for everybody. ... I kept thinking about what would be easiest for everyone else. Of course the easiest thing would have been if I'd lived. 29

Since thought disturbances and hopelessness are generally associated with depression, severely depressed people may not recognize the serious nature of their problem, or, i f they do, they may lack the will to try to get help: "Their thought processes often seem tailored to narrow possibilities, for their rigidity often makes them unable to see al-

ternative solutions, while depression alters their judgment about possibilities for the future."

30

W h e n I was nineteen, I had my first deep depression. I was terrified. Everything—the way I walked, the way I talked— slowed to a crawl. I felt empty, like everything inside me had been cut up and pulled out. It was as if something had died inside me and was disintegrating. I couldn't concentrate. Reading a book, I'd find myself skimming the same passage over and over until I'd realize I had read the same paragraph sixteen times. After eight months I began to wonder whether my depression would ever lift. I envisioned spending my whole life like that.The feeling that it was never going to end is what made me think of suicide. 31

The author of this passage, Anne-Grace Scheinin, made six suicide attempts in the two years before being diagnosed as manic-depressive and being treated with lithium. There were no suicide attempts in the following ten years. 5. Talking, or dropping clues, about committing suicide. This is usually an indirect, but unmistakable, plea for help, and shouldn't be ignored. Adolescents, in particular, generally place high value on independence, privacy, and self-reliance. If they're asking for help, they're probably in serious pain. 32

The idea that people who talk about suicide won't carry it out is dead wrong. Erwin Stengel estimates that three-fourths of the people who either commit suicide or make an attempt give clear warning of their intent; perhaps some act because they were not taken seriously. On the other hand, depression is often hidden (remember Thoreau's caveat, "The mass of men lead lives of quiet desperation") or unnoticed. Thus, as discussed later, physicians often don't recognize depression in their patients.

Suicide and Attempted Suicide • 57 RISK FACTORS FOR SUICIDE

One identification strategy takes a statistical look at the social, biological, and psychiatric components associated with suicide: Are there characteristics that suicidal people tend to share? One small study looked at a few such risk factors among New York teenagers: In Table 7.1, below, column 2, the "odds ratio," shows the relative likelihood of someone with a particular risk factor killing themselves, compared to similar persons without that trait. In this study, the greatest risk factor was a prior attempt, 22.5 times the general population rate. 33

Among the lowest-risk group, there were no suicides within two years; in the highest-risk group there were 57 (20.7 percent). Nevertheless, even in the highest-risk set of a high-risk population, four out of five did not kill themselves. The fact that the U.S. suicide rate has been fairly stable over several decades suggests that our ability to identify and treat the suicide-prone has not improved much, though it's certainly possible that the rate would be higher without such improvements as have occurred. In other words, our ability to anticipate—using any or all sociological, psychological, or biological measurements now available—whether a particular individual will or will not commit suicide, remains negligible. In the words of psychiatrist Alex Pokorny,

Suicide and Attempted Suicide • 59 Although we may reconstruct causal chains and motives after the fact, we do not possess the tools to predict particular suicides before the fact... .The conclusion is inescapable that we do not possess any item of information or any combination of items that permit us to identify to a useful degree the particular persons who will commit suicide.... Even for someone in a high-risk category the chances of suicide within a year are much less than the chance that he will not have committed suicide within that time. In twenty-five years I can remember perhaps three cases where I felt the chance of a certain person committing suicide within the next year was more than 10 percent. c

35

Pokorny makes a distinction between long-term prediction, about which he is pessimistic, and short-term crises (minutes, hours, or days) which, he argues, require identifying a crisis that is already here, and which, he feels, psychiatrists do reasonably well. However, clinical judgment seems unreliable for predicting suicide attempts: A computer program was superior to experienced clinicians in identifying patients who would attempt suicide. The current situation still seems to be, 36

No one knows why people kill themselves. Trying to find the answer is like trying to pinpoint what causes us to fall in love or what causes war. There is no single answer Suicide is not a disease like cancer or polio. It is a symptom. "The problem of suicide cuts across all diagnoses," says John Mack a psychiatrist and coauthor of Vivienne, the story of a fourteen-year-old girl who hanged herself. "Some are mentally ill, most are not. Some are psychotic, most are not. Some are impulsive, most are not." Says psychologist Pamela Canton "People commit suicide for many reasons. Some people who are depressed will commit suicide, and some people who are schizophrenic will commit suicide, and some people who are fine but impulsive will commit suicide. We can't lump them all together." And just as there is no one explanation for the five thousand adolescent suicides each year; there is no one explanation for any one suicide. 37

38

60 • Geo Stone Does bringing up the subject of suicide with a depressed person put the idea into her head? No, you can be sure that the idea was already there. However, "If they are feeling suicidal, it can come as a great relief to see that someone else has some insight into how they feel." 39

WHAT DO SUICIDE-ATTEMPT SURVIVORS THINK OF SUICIDE? Many people have speculated that if you could talk to someone who was in midair after jumping from a tall tower, you might find out that he no longer was so sure he wanted to die. O v e r the past thirty years I have seen four people who survived six-story suicide jumps. Two wished to survive as soon as they jumped, two said they did not, but one of the latter two who professed to be furious at having survived made no subsequent suicide attempt. 40

Similarly, of 515 people who had been prevented from jumping off the Golden Gate bridge, only 25 (5 percent) went on to kill themselves later. Of eight known survivors in 1975, one subsequently killed himself. According to another source, only 2 percent of survivors of suicide attempts objected to having been saved, while 70 percent said their suicide attempt was "stupid." The same author, Jaques Choron, cites Japanese data that claim 90 percent of survivors studied were happy to be saved. Similar studies from Norway found that 57 to 75 percent of suicide survivors said they were glad that their attempt had failed. 41

42

43

44

It seems also to be the case that surviving a serious suicide attempt sometimes ends depressions —even if there is permanent injury. Hendin suggests that sometimes a self-inflicted permanent injury is "therapeutic" in the sense that it satisfies a need for self-punishment. On the other hand, our inability to interview dead people—generally the most serious and thorough of attempters—limits our knowledge of their interest in being saved. 45

46

Suicide and Attempted Suicide • 61 HOW DO CLINICIANS TREAT SUICIDAL PEOPLE? The immediate goal of a therapist, counselor, or anyone else dealing with highly suicidal people should be to reduce the pain in every way possible.... Help them by intervening with whoever or whatever is causing their distress—lovers, parents, college deans, employers, or social service agencies. I have found that if you reduce these pressures and lower the level of suffering, even just a little, suicidal people will choose to live.

47

This is not always as gratifying as it sounds: Some suicidal people are "extremely difficult: provocative, ambivalent, openly hostile, or passive-aggressive and vengeful." Thus, 48

The clinician's first job is to manage his or her own feelings generated by the crisis situation and not be driven by discomfort.The clinician can act out in a variety of ways, from failing to inquire about suicidality with an obviously upset or depressed person ("It sounds bad, but surely you're not suicidal"); by fleeing from the subject when the patient brings it up ("Uh-huh. A n d how's your appetite?"); by actively colluding with the patient's wish to commit suicide ("Sounds like there isn't any reason for you to live"); or by openly or covertly directing the patient to die ("Why don't you do it right the next time!") 49

CAN TREATMENT PREVENT SUICIDE ATTEMPTS? Though often useful, professional help is no guarantee against suicide. Two-thirds of the suicides in one study had consulted their family doctor within a week of their death. In another study, over 90 percent of suicides had been seen by a psychiatrist or a family doctor within a year of death; 48 percent within a week. However 48 percent of physicians were "very surprised" by the suicide of their patient. 50

51

52

In fairness to the physicians, most of these people came in with somatic complaints: headache, insomnia, tiredness, backache, and so forth. In addition,

62 • Geo Stone patients are often on their best behavior at the doctor's and tend to minimize their psychiatric problems. It's also the case that a substantial number of these suicides saw the physician specifically to get enough drugs to kill themselves. In one study, this motivation was found in 43 percent of drug-overdose deaths immediately (within twenty-four hours) following physician visits. A l l of this does not imply that therapy is useless or counterproductive—any more than the fact that many people who see heart specialists end up dying from heart disease—only that it is far from universally effective. 53

d

On the other hand, current antidepressant drugs are fairly good at making people feel better—about 75 percent of users seem to be helped —and should certainly be tried by just about anyone considering suicide. However, they don't work instantly and might take as long as six weeks to show an effect, and the dose may need to be adjusted for an optimal response. Drug treatment should be generally continued for several months; less than 4.5 months of antidepressant use is associated with an increased rate of treatment failure. In addition, most of these drugs work for some people but not for others, possibly requiring trials with more than one antidepressant. In a study of people in New York City who killed themselves between 1990-92,16.4 percent (268 in 1,635) had been taking antidepressants. This is similar to data from Sweden where 15.9 percent (542 in 3,400) of suicides had been using antidepressants. It is not clear if this is good news (a lot of suicides might not have killed themselves had they been using medication) or bad news (a lot of people taking antidepressants kill themselves anyway). 54

55

56

57

58

In fact, while most antidepressants are reasonably good at making people feel better, they are less effective in decreasing suicidal thoughts and behavior. This is particularly true of the older tricyclics (TCAs) such as amitriptyline (for example, Elavil) and imipramine (for example, Tofranil). In fact one, maprotiline (Ludiomil), significantly increased suicidal behavior—14 suicide attempts among 777 patients compared to 1 attempt among the 374 patients taking no medication. Particularly interesting is that a low dose was just as suicide-provoking as a higher dose, while less effective in decreasing depression. The implication is that lower doses of such drugs, sometimes chosen for "safety," may be equally dangerous and less therapeutic than higher doses. Curiously, none of the five completed suicides was by maprotiline overdose, even though it is a fairly toxic drug. 6

59

Suicide and Attempted Suicide • 63 More recent antidepressants of a type called "serotonin-specific reuptake inhibitors" (SSRIs), like Prozac (fluoxetine), Welbutrin (bupropion) and Effexor (venlafaxine), seem to be safer, somewhat more effective, and faster acting than either T C A s or M A O I s , especially in severe depression or where there is a large anxiety component of the depression. However, there is some evidence suggesting that fluoxetine itself can cause suicidal thoughts and/or behavior. 60

But, even effective antidepressants can be a two-edged sword: Sometimes they make people feel just enough better to have the energy to kill themselves, as well as providing them the means to do so. Especially in adolescents and in people experiencing severe depression for the first time, it's important to remember the probability that, as Leigh O r f says, "in six short months someone who was threatening suicide daily will change their tune to 'Gee, am I glad I didn't off myself' because of some rather insignificant event, in the Grand Scheme of Things, like finding a new friend, S[ignificant] O[ther], or hobby."

How Do TELEPHONE HOTLINES WORK?

Hotlines provide an anonymous way for people to speak to a counselor about a problem. Some callers feel that they have no one they can talk to. For others, the telephone is simply less threatening than a face-to-face meeting would be. Assistance is available whether you're having a crisis yourself, are concerned about someone else, or just need someone to talk with. They generally do not provide "treatment," but usually have information about other available services that you may not have thought of. Hotlines are often staffed by volunteers—about one-third have no paid staff—and operate on shoestring budgets. As a result, they may be closed, or busy with other clients when you call. However, there is frequently more than one hotline locally available. Suicide hotline phone numbers may be found under "Crisis," "Suicide," or "Hotline" in the telephone book or in the Local Government listings. If you can't find one, you can call the American Association of Suicidology (202) 237-2280 for the nearest agency. Be aware that some suicide hotlines will call the police to trace a call i f they think the caller is about to kill herself; others will not. If this is relevant to you, ask first.

64 • G e o Stone

Surprisingly, there is little or no difference in the suicide rate in comparable communities that have hotlines and those that don't. This was found to be the case both in the United States and in England. A likely reason is that the most seriously suicidal people are the least apt to use such a service. Most of the legitimate calls (about half are cranks) are from unhappy people needing someone to talk with, but only a small fraction of them are suicidal. Only about 5 percent of suicides had been in contact with a hotline. 61

WHAT SUICIDE-RELATED RESOURCES EXIST ON THE INTERNET?

There is a lot out there, but there's no quality control on the Internet: caveat emptor. The Samaritans is probably the oldest organization offering suicide prevention counseling on the Internet. They are based in England and have been providing hotline and hands-on help for more than forty years. E-mail is read and answered 365 days a year. Note that the Samaritans will not break a caller's confidentiality on any matter pertaining to suicide. To reach them, send e-mail to: [emailprotected], or visit their web site: http://www.samaritans.org.uk. Nothing is 100 percent snoop-proof, but there are a number of "anonymous re-mailers" who will forward your e-mail while removing your identification. For more information about, and links to, these sites, try: www.anonymizer.com. However, be aware that using a re-mailer is often much slower (hours, rather than minutes or seconds) than direct e-mail. There are several discussion Usenet newsgroups under the alt.support hierarchy: alt.support.depression has been recommended by Graham Stoney as having a detailed and excellent Frequently Asked Questions posting covering many facets of depression. Other alt.support groups include: alt.suicide.holiday, or A S H , and a newer group, alt.suicide.exams which is most active around student-exam times. Note that (1) the Internet changes rapidly; (2) not all Internet service providers carry any or all alt groups.

How DOES SUICIDE AFFECT FRIENDS AND FAMILY?

The family is left to pick up the pieces, figuratively and sometimes literally. Such deaths often leave scars on family and friends: guilt, sorrow, anger, abandonment, silence. Even young children instinctively know this when f

Suicide and Attempted Suicide • 67 they scream (or fantasize) to their parents, "I'll die and then you'll be sorry!" Mark Twain describes this situation in Tom Sawyer's elaborate death ruse— he is supposed to have drowned, but is actually hiding under the bed listening while his Aunt Polly and her friend, Mrs. Harper, sorrowfully express their belated love and guilt at his untimely demise. In one study, all family members said they were shocked by finding the body or being informed of the suicide; 89 percent said they were later angry, and 57 percent reported depression. Some described persistent memories of the smell of gunpowder and finding bone and tissue parts. On the other hand, depending on attitudes and circumstances, sometimes the death is also a relief, particularly in cases of terminal illness or chronic suicidality. One 57-year-old woman said of her husband, "It was at the back of my mind that it was going to happen. A n d when it did, it was a shock, but I felt, 'Okay, he's finally at rest. . . .' I felt relieved that he was finally at peace, because I had done all I could." 62

NOTES a

P e r h a p s it w o u l d be m o r e useful to t u r n the question a r o u n d and ask, u n d e r what cir-

cumstances is suicide rational. G. C. G r a b e r argues that suicide is rationally justified "if a reasonable appraisal of the situation reveals that o n e is really better off d e a d " (Graber, 65). b

O n e historical impetus f o r this view is that b o t h E u r o p e a n (and E u r o p e a n - c o l o n i z e d )

states and the C a t h o l i c C h u r c h inflicted severe penalties f o r suicide (confiscation of p r o p e r t y and u n c o n s e c r a t e d burial, respectively) unless the d e c e a s e d was i n s a n e . T h u s , t h e r e was a t e n d e n c y f o r sympathetic c o r o n e r s (and later, psychiatrists) to find that, in English c o m m o n - l a w language, the individual killed himself "while the balance of his mind was disturbed." A n d while suicide is associated with mental illness in the W e s t , "In n u m e r o u s o t h e r . . . n o n - W e s t e r n cultures the association of suicide with mental illness seems to be m u c h less strong, and in s o m e cultures is quite l o w " (Battin, Issues, 6 ) . T h e s e are societies w h e r e philosophic or institutional suicide is c o m m o n , e.g., Japan, or India (Farberow, 1975). It is also cautionary to r e m e m b e r that until 1973 h o m o s e x u a l i t y was classified as a psychiatric p a t h o l o g y — a mental disease in need of t r e a t m e n t — b y the A m e r i c a n Psychiatric A s sociation. c

O n e major p r o b l e m with identifying potential suicides is that any c u r r e n t screening test

or c o m b i n a t i o n of tests that picks up a significant n u m b e r of p e o p l e intending suicide g e n erates t o o many "false positives." T h i s is a general p r o b l e m in the use of screening tests f o r u n c o m m o n o c c u r r e n c e s ( R o s e n , 1954).Thus, any currently available s c r e e n that will detect, say, 80 o u t of 100 future suicides will also (besides missing 20 suicides) wrongly identify many nonsuicidal p e o p l e as suicidal f o r each c o r r e c t identification. T h e p r o b l e m is o n e of designing tests with b o t h high selectivity and high sensitivity. A highly

68 • Geo Stone selective screen is o n e that distinguishes p e o p l e intending suicide f r o m all o t h e r s . An e x a m ple of a selective screen population might be the set of all p e o p l e standing on the edge of a cliff, holding a gun to their head. A large fraction of such p e o p l e are probably suicidal; there will be few false positives.The difficulty with such a selective screen is that it is n o t very s e n sitive—it might only pick up o n e suicide in a thousand since few m e e t the screen's criteria. On the o t h e r hand, a highly sensitive filter, f o r e x a m p l e , o n e that picks o u t all p e o p l e w h o are o n e o r m o r e o f the f o l l o w i n g — s c h i z o p h r e n i c , d e p r e s s e d , a l c o h o l i c , lonely, hopeless, elderly, a psychiatrist or female physician, have m a d e a previous attempt, or have a family hist o r y of s u i c i d e — m i g h t pick up 90 p e r c e n t of suicides, but also s c o r e s of nonsuicidal p e o p l e f o r each genuinely suicidal o n e . Such a sensitive test is t o o unselective to be v e r y useful. d

8 Is SUICIDE APPROPRIATE? Is INTERVENTION APPROPRIATE? WHO DECIDES?

It is not a thing to do while one is not in one's best mind. Never kill yourself while you are suicidal. —Edwin Shneidman 1

Never do today what you can put off till tomorrow. Delay may give clearer light as to what is best to be done. — A a r o n Burr

WHEN IS SUICIDE JUSTIFIED? People have been arguing this question for millennia. There are about one thousand books in print on suicide in the United States. Sherwin Nuland, physician and author of How We Die, puts it well when he says, "The i m portance of airing different viewpoints rests not in the probability that a stable consensus will ever be reached, but in the recognition that it will not. It is by studying the shades of opinion expressed in such discussions that we become aware of considerations in decision-making that may never have weighed in our soul-searching." 2

Some people think suicide is never justified. A minority argue the merits of suicide: It allows one to choose (as much as one can choose these things) the time, place, manner, cause, purpose, and painfullness of death, and pro3

ponents maintain that it is a decision each individual must make. Most of us would understand why someone might prefer suicide as opposed to unceasing and unbearable pain. Many would, I think, agree with Nuland when he says, "Taking one's own life is almost always the wrong thing to do. There are two circumstances, however, in which that may not be so. Those two are the unendurable infirmities of a crippling old age and the final devastations of a terminal disease." As philosopher Richard W. Momeyer puts it, a

5

Suicide is an act that does not occur in a vacuum, and it is ordinarily not without very serious and often devastating consequences for others. Even if it can be claimed as a right, it is not inappropriate that one be very careful to assure that exercising that right is the right thing to do. Having a right to do something provides us some entitlement to do it; it does not assure that doing it is right. It is appropriate to set very high standards of justification for exercising a right to suicide, given how often it is undertaken in an ill-considered manner, how frequently suiciders suffer diminished competence from mental illness, and how widespread and serious are the consequences for others. 6

INTERVENTION IN SUICIDE There seem to be two central questions about intervention to stop suicide: (1) Under what (if any) circumstances, and (2) by what means, is it appropriate? Most people would argue that suicide intervention is justified in the absence of terminal illness. This is especially true if the potential suicide is young; their thinking is impaired by depression, alcohol, or other drugs; they are ambivalent; or there's likelihood of "improvement," that is, a change of mind or condition. On the other hand, about two-thirds of Americans feel that suicide or euthanasia is sometimes proper for people who are dying. 13

7

However, the issue becomes less clear when one asks, "For how long, and by what methods, may the exercise of the right to suicide be limited?" For

Suicide and Attempted Suicide • 71 0

example, should someone be locked up or drugged solely because they may commit suicide? If so, for how long? In the United States, ... suicidal persons are the only people who may be held against their will for weeks, months, or even years on the sole basis of what they "might" do in the future rather than what they have done in the past—and not to others but to themselves. O n e Arizona woman spent fifty-eight years without comprehensive review in a state mental hospital after a suicide attempt. "If a sociologist predicted that a person was 80 percent likely to commit a felonious act, no law would permit his confinement," comment the authors of an article on "Civil Commitment of the Mentally III: Theories and Procedures" in the Harvard Law Review. " O n the other hand, if a psychiatrist testified that a person was mentally ill and 80 percent likely to commit a dangerous act, the patient would be committed." 8

The Supreme Court, in its wisdom, has seen fit to provide weaker safeguards of due process and standards of proof in civil commitment cases than in criminal cases. In criminal cases the standard of proof for guilt is "beyond a reasonable doubt" and the belief is that it's better for a guilty person to go free than for an innocent one to be unjustly imprisoned. In spite of this principle, the Supreme Court does not "appear to believe, as it does in criminal cases, that it is better for a mentally i l l person to go free than for a normal individual to be committed." Whether someone is involuntarily hospitalized depends, to a substantial extent, on social factors: age, sex, status—older, female, and lower socioeconomic-class people are more likely to be involuntarily committed —and whether the patient has a lawyer at the commitment proceedings. In addition, psychiatrists consistently overestimate the danger to and by the patient in commitment hearings. This is not surprising, since (1) psychiatrists' ability to accurately predict who will commit suicide is small, and (2) the consequences to the psychiatrist, and (perhaps) to the patient, are much more severe if a released patient commits suicide than if the psychiatrist mistakenly hospitalizes someone. A n d , if the patient kills himself 9

while hospitalized, this can be cited as evidence of the need for the hospitalization, however regrettable the outcome. Is ambivalence about suicide—for example, seeking help, calling a hotline, or standing on a ledge—sufficient grounds for intervention? Ambivalence means wanting, or being undecided between, two mutually exclusive things, in this case, life and death. The problem with suicide is that we can go from life to death, but not from death to life; a hundred decisions for life are overcome by a single one for death. One can argue that what suicides want is not death but the end to their pain, however it be achieved, and that if life equals pain then death equals end-of-pain. The results, however, are the same. Ambivalence toward suicide is indicated by the fact that threefourths of all suicides communicate their intentions, often with the hope that something will be done to make their suicide unnecessary. In a high proportion of cases, such communications are varied, repeated, and expressed to more than one individual. Studies of those who have survived a serious suicide attempt have revealed that a fantasy of being rescued is frequently present. 13

But even if we can agree that intervention is sometimes appropriate, what are we to do with the suicidal people who do not agree? May we force them to take mind-altering drugs? For how long? Electroshock? H o w many times? Lock them up? For how many days, months, years? By what right may we continue to intervene in the face of someone's persistent demand to make the decision as to the time and manner of their death? Ultimately the question cannot be evaded: Whose life is it? As Frederick Ellis eloquently puts it, "[Death] is my final civil liberty, and I do not choose to surrender it to the state, a church or a physician." 14

DOES HOSPITALIZATION HELP? In the heat of this argument, an important question is often overlooked: Does hospitalization help? The answer is far from clear. Suicide rates in psychiatric hospitals are roughly five times higher than they are on the out-

side, and there have been suicide epidemics inside such institutions. Some of the antisuicide regimens, such as twenty-four-hour-a-day watch or isolation, may be terrifying or enraging to the patient/prisoner, and may be imposed because of the staff's fear of being accused of not having done everything possible to prevent a potential suicide. Some evidence that has been uncritically used to support hospitalization is subject to other interpretations. For example, one study found that a significant number of hospitalized mental patients killed themselves while temporarily at home on leave. This was taken to mean that it was the return to the scene and situation at home that triggered the suicide. The notion that an unwillingness to go back to the hospital might have been the catalyst was never examined. Similarly, the fact that 7 percent of a group of recently released psychiatric patients killed themselves was used to make a case for hospitalization. But, as psychiatrist Herbert Hendin notes, 17

18

There is as much justification for concluding that.. .the experience of hospitalization contributed to the suicide as there is for maintaining that hospitalization would have prevented it.... For some acutely suicidal patients it may be life saving.... Other suicidal patients are made more upset by their confinement.The decision for hospitalization is too often made, not on the basis of a realistic evaluation of whether it will help a particular patient, but because therapists want to shift the responsibility for a possible suicide onto an institution. 19

DISCOMFORT WITH SUICIDE We're all going to die eventually; the only uncertainties are when and how. Why, then, does suicide bother us in a way and to a degree that numerically greater—and easier to prevent—causes of death, like automobile wrecks (40,000 to 50,000 per year) or cigarette smoking (400,000 per year) don't? Writer Jacques Choron speculates, It has been suggested that suicide "troubles and appalls us because it so intransigently rejects our deeply held conviction that life must be worth living." 20

74 • Geo Stone While there is undoubtedly some truth in this, in more cases than one would like to admit the reason for the shock may not be the challenges to the belief that life is good, but the fact that one is not really quite sure that it is. As . . . [Spanish philosopher] Jose Ortega y Gasset noted, for most people at all times "life" meant limitation, obligation, dependence, and oppression. They go on living simply because they happen to have been born, sustained by the force of habit, sometimes out of curiosity or vague hopes for a better future, and because they are afraid of the alternative— death. But the suicide seems to have conquered this fear. Thus he confirms not only the suspicion that life may not be the highest good but the one that death may not be the greatest evil. 21

22

Choron goes on to ask, Should not the multitudes who die painfully and miserably each year be allowed to decide for themselves what is best for them? Moreover, it would be interesting to ascertain how many among physicians, whose suicide rate is many times that of the average population, are actually euthanasic suicides, due to the discovery of their own terminal illness, their knowledge of how prolonged and painful dying can be, and the easy accessibility of quick-acting lethal drugs. 23

Good question. Consider these statistics: about 3 percent of male and 6.5 percent of female U.S. physicians' deaths in 1986 were suicides; 35 percent of premature deaths among physicians were due to suicide; suicide is the leading cause of death for physicians under 40 years old; and the suicide rate for psychiatrists is almost twice that for other doctors. 24

25

26

27

Data from Australia also show moderately elevated suicide rates for male physicians, and substantially higher rates for female doctors.

Switzerland, the problem is so severe that the life expectancy of female physicians is ten years less than that of the general female population.

9 ASSISTED SUICIDE AND TERMINAL ILLNESS

Whereas a prolonged life is not necessarily better; a prolonged death is necessarily worse. —Seneca I believe often that death is good medical treatment because it can achieve what all the medical advances and technology cannot achieve today, and that is stop the suffering of the patient. —Christiaan Barnard 1

PROLONGED DYING Dying has changed drastically over the last century. In 1900 the life expectancy in the United States was forty-seven years; by the mid-1990s it had risen to seventy-seven. Whereas, in earlier times, people typically died quickly from infectious disease or infections following injury, now most Americans are living long enough to develop degenerative diseases: heart disease, diabetes, stroke, cancer. Now, 70 to 80 percent of us will die of something we have for months or even years. Four out of five Americans now die in an institution: hospital, nursing home, or other extended-care facility in which, 2

76

Suicide and Attempted Suicide • 77 typically, patients forfeit control over what to wean when to eat, and when to take medicines, for example. Furthermore, they almost inevitably lose substantial privacy—intimate body parts are examined, highly personal facts are written down, and someone they have never seen before may occupy the next bed. Finally, trust must be placed in strangers selected by the institution: Care is given by professional experts who might well be, and who frequently are, substituted freely for one another to accommodate work schedules and institutional needs. All of these factors serve to isolate patients, rob them of their individuality, foster dependence, and diminish self-respect and self confidence, even when illness, medication, and surgery have not already had these effects. 3

In addition, the infrequency of home deaths has drawn a curtain of ignorance around dying, which make it easier to misunderstand and—up to the point of personal involvement—neglect the process. Medical ability to maintain hopeless life has increased tremendously. Social critic Ivan Illich calls this "managed maintenance of life on high levels of sublethal illness" the "ultimate evil" of medical progress. We're still sorting out the individual, social, and medical consequences of the widespread shift from acute to chronic disease, from dying at home to dying in a hospital, from dying quickly to dying slowly. Illness-driven suicide and euthanasia are two of these consequences. 4

5

Between 1920 and 1993, 519 cases of mercy killing were recorded in the United States. Ninety-two percent of these have occurred since 1973, suggesting one response to prolonged, high-tech dying—or to the fear of it. The frequency of suicide among the terminally i l l is in dispute. Studies of cancer patients have found suicide rates ranging from the same as to ten times that of the rate among the general population. The reported rates are probably substantial underestimates, however, since families are relatively unlikely to confess to a suicide and physicians or medical examiners unlikely to investigate deaths under these circumstances. In addition, dying patients may be unwilling to admit to suicidal thoughts or plans for fear of being classified as "depressed" and being deprived of pain-relieving drugs. 6

ASSISTED SUICIDE AND EUTHANASIA

M u c h has been written on the topic of assisted suicide and euthanasia, and I will add only a few passing observations. First, there is a good deal of confusion about language, particularly concerning the terms "assisted suicide" and "euthanasia." Though they are often used interchangeably, in this book the distinction is that in assisted suicide, while someone else provides the lethal agent, the person who is dying administers it; in euthanasia, someone else does the administration. Assisted suicide is probably easier on the assistant's conscience than euthanasia and does decrease the possibility of misunderstanding or abuses; however, it also substantially increases the chance of other errors, such as the patient falling asleep before swallowing a lethal dose or vomiting it up. On the other hand, where a dying patient has made the request for such help clear, but has lapsed into physical or mental inability to act, assisted suicide would no longer be an option. Euthanasia may be voluntary, where the person dying has made a request for it. It may be nonvoluntary, where a person who has not made her wishes on this matter known is put to death; such people are often in a coma. "Involuntary euthanasia" might be the oxymoronic term if the person dying had expressed opposition to such a procedure. The more common word for this is murder. Assistance may be active, for example, administering a lethal injection; or passive, such as disconnecting someone from life-support apparatus. Thus, Dr. Jack Kevorkian has carried out, so far, passive-assisted suicides. He has, in most cases, set up a carbon monoxide apparatus that requires the patient to open a valve to start the gas flow. (His first three assisted suicides were accomplished by means of intravenous potassium as the lethal agent. However, starting an IV line is not always easy, which may be why Kevorkian subsequently switched to carbon monoxide.) Some people believe there is an ethical or moral difference between active and passive euthanasia. However, as Lonny Shavelson notes, "the major difference today between passive and active euthanasia is that people who believe in passive euthanasia are allowed to have it; for those who would choose active euthanasia, it is forbidden." Or, in the words of Dr. Pieter 9

10

Suicide and Attempted Suicide • 79 Admiraal, "the only thing passive about passive euthanasia, is the physician" 11

While there is an obvious difference between "killing" and "allowing to die," those who feel that there is a clear moral distinction between the two seem to be saying that we may allow an evil—choosing to die—by acts of omission, but may not commit the identical evil by acts of commission. Would it then be morally acceptable to stay aboard a sinking ship to make room for someone else in a lifeboat, but not to jump out of a lifeboat for the same purpose? W h y is it legal and ethical to act on a terminally i l l patient's request to turn off her ventilator, but illegal and unethical to carry out the same patient's request for an overdose of morphine? Is it not as much a choice to die from asphyxia or cancer as from an overdose? In the ethical triad of intent, method, and result, when the intent and result of passive (for example, removing life support) and active (for example, administering a lethal overdose) euthanasia are the same, it seems obtuse to ignore those similarities and focus on differences of method. I would suggest that to turn off life-support and let the patient die "naturally" hours or days later is often the immoral act. If a dying person's condition is so hopeless or painful that withdrawal of life-support is appropriate, then the most merciful action is that which brings this life to an immediate end. In Margaret Battin's words, "To impose 'mercy' on someone who insists that despite his or her suffering life is still valuable to him or her would hardly be mercy; to withhold mercy from someone who pleads for it, on the basis that his or her life could still be worthwhile for him or her, is insensitive and cruel." 12

"ACTIVE" VERSUS "PASSIVE" METHODS OF DYING

While the ethical arguments when someone in a coma has not made their desire for (or disapproval of) an expedited death known are more complex than in assisted suicide, the distinctions between "active" and "passive" are solely differences of method rather than intent, result, or consent, and of little independent ethical interest. Except that method matters. When a physician removes food and water IVs from a terminal patient, fully expecting and intending that the patient

80 • G e o Stone

will die within a few hours or days as a result of this action, why does he or she not administer a lethal drug and put an end to the suffering? What is the lofty ethical principle being preserved here? Keeping one's hands clean? The dog pound treats injured strays better. In fairness to physicians, a major reason for their aversion to "actively" hasten death is, I think, that it remains illegal to do so. As a result, a tormented patient is at the mercy of the doctor's willingness to take risks, put his or her own career on the line, and perhaps go to jail. In 1991 Dr. Timothy Quill, professor of medicine and psychiatry at the University of Rochester Medical School, gave a dying patient a prescription for a lethal quantity of barbiturates knowing that she intended to kill herself with them. After Quill bravely (or foolishly) wrote about it in a letter to the New England Journal of Medicine, : Rochester, New York, prosecutor Howard Relin ("the People") tried to get a grand jury indictment on a charge of assisting a suicide, which carries a five- to fifteen-year prison sentence. The grand jury (the People) refused. 13

Eleven physicians since 1935 have been charged with murder in mercykillings (eight of these since 1980); most were acquitted, one committed suicide, none served prison time. Still, such legal sanctions discourage physicians from both assisted suicide and euthanasia even when all parties involved agree that it would be the right, as well as the best, thing to do. A n d while individual doctors may carry out assisted suicide or euthanasia, as Anthony Flew notes, "it is entirely wrong to expect the members of one profession as a regular matter of course to jeopardize their whole careers by breaking the criminal law in order to save the rest of us the labour . . . of changing that law." Flew makes a valid point. Nevertheless, I find the withdrawal of food and water inexcusably cruel: It is the socially acceptable torture of the helpless due to the moral cowardice of legislators, physicians, and the public. 14

15

RIGHT TO REFUSE MEDICAL TREATMENT

Oddly, in the midst of the heated assisted-suicide debate, there is little discussion of the generally accepted, and legally undisputed, right to refuse medical treatment, even when the refusal will directly lead to death. a

Suicide and Attempted Suicide • 81 For example, the death of about one in five kidney dialysis ("artificial kidney") patients is due to quitting dialysis —knowing that they will die within two weeks as a result of their decision. The average survival time is a little over a week. 16

15

17

There are also large numbers who refuse blood transfusions, chemotherapy, or surgery for a variety of personal or religious reasons. The ethical distinction between refusing treatment in order to die and suicide (assisted or not) for the same purpose is not apparent. Nevertheless, treatment refusal often does not lead to a "good" death: one that is painless, dignified, conscious, and leaves time to review one's life and say good-byes. Moreover, the definition of a "good" death varies from one person to the next. For some people it is the least painful, for some it is the fastest, for some it is the most delayed, for some it is the least disfiguring, for some it is that which best allows final conscious time with family and friends. These preferences provide all the more reason to respect the autonomy and choices of each individual. In the United States treatment refusal is the only legally protected method for choosing death. It is available to (legally) competent and (indirectly, through proxy) noncompetent individuals. This right was asserted by courts at least as early as 1914: "Every human being of adult years and sound mind has a right to determine what shall be done with his own body." More recently, in Griswold v. Connecticut and Roe v. Wade, the U.S. Supreme Court reached similar conclusions, based on a constitutional right to privacy. The Ninth Circuit Court of Appeals used this as the basis for overturning the Washington State ban on assisted suicide. A month later, in A p r i l 1996, the Second Circuit Court of Appeals overturned New York's ban on assisted suicide, but used the "equal protection" clause of the Fourteenth Amendment as the rationale, noting that terminally i l l people who were on life-support could legally "pull the plug," while those not on lifesupport had no similar option. In June 1997, the Supreme Court reversed the two Appeals Court decisions and ruled that there is no constitutional right to physician-assisted suicide. They seem to have been unpersuaded by the part of the (New Jersey Supreme Court) Quinlan (1976) decision that stated: 18

82 • G e o Stone

Constitutional protection from criminal prosecution where death is accelerated by termination of medical treatment pursuant to right of privacy extends to third parties whose action is necessary to effectuate the exercise of that right where the patients themselves would not be subject to prosecution or the third parties are charged as accessories to an act which could not be a crime. 19

Thus it remains legal to pull the plug on a respirator and let a permanently comatose patient suffocate, but a crime—murder—to end that same life by a deliberate overdose of painkiller.

"NATURAL" PROCESS VERSUS "ARTIFICIAL" INTERVENTION The assertion has been made that there is a crucial difference between "pulling the plug" and deliberate overdose: One consists of letting a "natural" process continue while the other is an "artificial" interference with that process. This claim is absurd. W h y is it only ethical to die "naturally," after a long illness filled with highly unnatural life-extending medical procedures? W h y is it unethical to choose to die swiftly and painlessly? Scottish philosopher David Hume addressed the theological form of this argument around 1750: Were the disposal of human life so much reserved as the peculiar province of the Almighty that it were an encroachment on his right, for men to dispose of their own lives; it would be equally criminal to act for the preservation of life as for its destruction. If I turn aside a stone which is falling upon my head, I disturb the course of nature, and I invade the peculiar province of the Almighty by lengthening out my life beyond the period which by the general laws of matter and motion He had assigned it. 20c

Thus the argument by "natural physical law" fails: If one may intervene in some natural laws, one may intervene in others; and suicide cannot be opposed on these grounds. That is, one must also show that some laws of nature, but not others, should be left alone.

Suicide and Attempted Suicide • 83 In any case, the natural law argument is fundamentally flawed, since it claims the existence of a natural physical law (in this case, that suicide is contrary to the "law of self-preservation") as the justification to enforce obedience to that same law. However, to the extent that what is called a natural law really is one, it doesn't need legislative or moral reinforcement: The law of gravity seems to work equally well with or without human approval.

CONSEQUENCES OF LEGALIZING ASSISTED SUICIDE There are numerous cases of desperate, hospitalized people carrying out desperate suicides. In one instance, a man dying of cancer, immobilized in a frame and partly paralyzed, poured lighter fluid on his chest and ignited it. In another case, "one terminally i l l seventy-eight-year-old, who was intubated and connected to life-support systems despite repeated requests to be left alone to die, switched off his own ventilator during the night and suffocated. He left a final message for his attending physician: 'Death is not the enemy, doctor. Inhumanity is.'" In Richard Momeyer's words, 21

A decent society finds ways of caring for those even in the most extreme distress; rarely is it the case that such caring is best done by encouraging death, either through suicide or euthanasia. Rarely, I said, but not never. For neither is it the case that in a decent society we would burden those for whom death is in their best interest with the sole responsibility for ending their lives, any more than we burden everyone with sole responsibility for sustaining their lives when this is best. 22

One of the ironic and presumably unintended results of making assisted suicide illegal is the pressure it puts on the old, infirm, and ill to kill themselves while they are still able to do so, and sooner than they would if they could count on help. Part of author Arthur Koestler's suicide letter addresses this issue: "After a more or less steady physical decline over the last years, the process has now reached an acute state with added complications which make it advisable to seek self-deliverance now, before I become i n d

84 • Geo Stone 23

capable of making the necessary arrangements." Nobel physicist Percy Bridgman, dying from cancer, shot himself after his physician refused to help him die. He left the following note: "It isn't decent for society to make a man do this thing himself. Probably this is the last day I will be able to do it myself." Koestler's and Bridgman's concern was not without foundation: Sometimes people wait too long. A I D S patients are particularly prone to suicide, but doctors who have many A I D S patients say that they have often seen these people prepare to kill themselves, but then become demented from their disease and thus unable to carry out their plans. What should physicians do under these circumstances? Margaret Battin, a medical ethicist, argues: 24

25

The physician's obligation is not only to respect the patient's choices, but also to make it possible for the patient to act upon those choices.This means supplying the knowledge and equipment to enable the person to stay alive, if he or she so chooses.... But it may also mean providing the knowledge, equipment, and help to enable the patient to die, if that is his or her c h o i c e . . . . To restrict the right to die to the mere right to refuse unwanted medical treatment and so be "allowed" to die . . . is an indefensible truncation of the more basic right to choose one's death in accordance with one's own values. 26

27

On the other hand, the capability of committing suicide sometimes decreases the perceived need to do so prematurely. In 1994, George Kingsley was a forty-eight-year-old man with A I D S . He collected the pills he intended to use and gave away many of his possessions: "[Having the means to kill myself] has made my every day better, much much better," he said. "It has diminished my horror, as though I was facing an enemy on a battlefield stark naked and now I have armor." 28

Data from the Netherlands are consistent with this idea. Twenty-two percent (29 out of 131) of a group of A I D S patients died by physician-assisted suicide (PAS) or euthanasia, compared to about 2 percent of all deaths. Based on an examination of each case, "[There was not] any substantial

Suicide and Attempted Suicide • 85 shortening of life by euthanasia/PAS . . . most of these patients would have died naturally within one month." 29

When physicians singlemindedly fight against death, it is, too often, at the expense of their equally important obligation to ease suffering. It is a medical atavism based on an acute-illness model that doesn't apply: "If we can pull them through this crisis, they'll recover sufficiently to have a worthwhile remaining life." In many situations, they won't. The use of so-called "heroic" measures to maintain and resuscitate a terminally i l l person who wants to die can better be described as "killing slowly and without mercy."

PHYSICIANS' AND NURSES' VIEWS From Australia comes an eloquent Open Letter to the State Premier (Governor) of Victoria: Each of us who has signed this letter has personal experience of treating terminally ill patients whose condition has moved them to ask for assistance in suicide and each of us has, on occasion, after deep thought and lengthy discussion, helped such a patient to d i e . . . . W e have assisted patients to end their lives and we know others who have. We believe that we have acted in the best tradition of medical ethics, offering our patients relief from pain and suffering in circumstances where it would have been an act of cruelty to deny them. We respect life. All of our professional training and work deepens that respect. However; the reality is that there are some patients who are beset by physical and mental suffering which is beyond the reach of even our most sophisticated efforts at control. W h e n such patients clearly and repeatedly express a rational plea for help, it is out of respect for them that we have felt compelled to act. However; as long as the law maintains that our behaviour is criminal, there will be numerous patients who will die in unnecessary misery.There are many who cry out for help and who are denied it by doctors who may sympathise with their plight but who are unwilling to break the law.There are some who attempt to end their lives unaided and who botch the attempt and survive

86 • G e o Stone

with their misery redoubled.There are others who may be helped by a doctor but who, for fear of incriminating their friends and family, must choose to die alone without the chance to say farewell.

Increasing numbers of doctors and nurses throughout the world have reached similar conclusions. The Medical Journal of Australia published a 1988 survey that found 60 percent of physicians in Victoria wanted the law changed to decriminalize assisted suicide under some circumstances; 78 percent of nurses in Victoria agreed. Of those Australian doctors who treated incurably i l l adult patients, 29 percent had "actively" hastened the death of some who had asked to die; 80 percent had done this more than once. In another state, New South Wales and the Australian Capital Territory, almost half of 2,000 surveyed physicians had been asked to carry out euthanasia; 28 percent had done so. A survey of California physicians arrived at generally similar numbers, with 23 percent of doctors having quickened a patient s death. Among San Francisco Bay area doctors with substantial A I D S practices, it was 53 percent. A more recent national sampling found 7 percent of U.S. physicians had written lethal prescriptions or given lethal injections. Most had done so infrequently, but one reported assisting 175 deaths. Nurses act in much the same way. Seventeen percent (141 in 852) of American critical-care nurses surveyed had been asked by patients and/or patients' families to carry out euthanasia (which included high doses of pain medication that results in both pain control and life shortening, but excluded withdrawal of life-support equipment); 16 percent (129) had done so, and an additional 4 percent (39) said they had hastened patients' deaths by withholding life-sustaining treatment ordered by a physician. Most said they had done these three or fewer times; however 5 percent said they had done so twenty or more times. 30

31

32

33

34

35

In Canada, 44 percent of surveyed physicians said that physician-administered euthanasia was sometimes justified; 51 percent said that the law should be changed to permit patient-requested active euthanasia. In the Netherlands, where both euthanasia and assisted suicide have been more or less openly practiced since 1973, physician approval is around 80 to 90 percent. 36

37

Suicide and Attempted Suicide • 87 In the United States, medical opinion is closely divided. A 1993 survey of 938 doctors in Washington State found that half supported physician-assisted suicide in some cases, while 39 percent said it was never justified. Forty-two percent felt that it was acceptable for the physician, rather than the patient, to administer the lethal overdose, while 48 percent said it was not. Interestingly, psychiatrists were most likely to support physician-assisted suicide; cancer specialists least likely. Female doctors were significantly more favorable toward assisted suicide than were their male colleagues. One wonders if psychiatrists and female physicians might also be higher in measures of empathy and compassion. A more recent study, published in 1996, found increased physician support. Sixty percent of the Oregon doctors most likely to work with terminally i l l patients (out of 2,761 responses) favored physician-assisted suicide under some circumstances. Older doctors were more approving than younger ones; perhaps they are more realistic about the limits of medicine. Catholics, nondenominational Christians, and Mormons were less likely to approve than were other religious affiliations. Twenty-one percent of these doctors had been asked to write a prescription for a lethal drug dose in the previous year; 7 percent had done so. 38

6

39

40

Meanwhile in Michigan, 77 percent of doctors felt that physician-assisted suicide should either be explicitly legalized (40 percent) or that there should be no law at all concerning it (37 percent); only 17 percent said it should be illegal. Thirty-five percent said that they might carry out such assistance, if legal. Among Michigan cancer specialists, 18 percent admitted to assisting in suicide(s) and 4 percent to carrying out euthanasia. The American Medical Association's governing body recentiy reaffirmed its longstanding opposition to physician-assisted suicide —while simultaneously respecting a dying patient's wishes concerning treatment and maintaining the position that a doctor may withdraw all life-support treatment, including food and water, from a patient who is in an irreversible coma. To hold these views simultaneously is an impressive intellectual feat. However, there has been increasing protest: One delegate argued that the official A M A position "fails to respond to the crying need of our patients in prolonged agony." Another said he was amazed by the number of fellow doctors he had polled who had admitted assisting suicides. 41

42

43

44

45

88 • G e o Stone

Significantly, a large majority—almost 90 percent—of doctors and nurses surveyed said that they would not want treatment if they had severe dementia or were in an irreversible coma. In the case of a possibly reversible coma, 70 percent of the nurses and half of the physicians said that they would not want treatment. In the words of the study's authors, "physicians and nurses, who have extensive exposure to hospitals and sick patients, are unlikely to wish aggressive treatment if they become terminally i l l , demented, or are in a persistent vegetative state. Many would also decline aggressive care on the basis of age alone." 46

Yet they are willing to inflict treatment on patients in comparable circumstances. In the hypothetical case of a demented elderly patient with lifethreatening gastro-intestinal bleeding, physicians were more than twice as likely to want only palliative (comfort) care i f they were the patient than i f the patient were a stranger. This attitude is also seen in "active life termination" issues. In interviews with 155 cancer patients, 193 members of the public, and 355 oncologists (cancer doctors), about two-thirds of the patients and public thought doctor-assisted suicide or euthanasia were acceptable for patients in uncontrollable pain. Less than half of the physicians agreed; however, almost one in seven had carried out such acts. 47

48

PUBLIC OPINION

Nonmedical opinion has also moved in the direction of increased acceptance of life termination. Barbara Logue has collected a series of public opinion surveys published between 1937 and 1991. They all show a gradual, but remarkably steady, shift from about two to one opposed to euthanasia-assisted suicide to two to one in favor. What is most striking about these data is that every multiyear poll shows increasing approval for every time interval. This was true irrespective of who (Gallup, Harris, Roper, General Social Surveys) carried out the survey or how the questions were worded. A typical survey question, from Harris polls between 1973 and 1985 is: "Do you think the patient who is terminally i l l , with no cure in sight, ought to have the right to tell his doctor to put him out of his misery, or do you think this is wrong?" The response to this par49

When these questions were asked only to the elderly, whose interest in such matters is least likely to be abstract or hypothetical, a similar pattern of increasing approval was also seen. The impetus for this shift has not come from the medical, legal, or political establishment, which has, in typical conservative fashion, generally resisted change. Rather, the pressure for change has been the result of the experiences of millions of the slowly dying, their families, and increasing numbers of their physicians. 50

10 THE MEDICAL SYSTEM IN TERMINAL ILLNESS

Life must go on. I forget just why. — E d n a St.Vincent Miliay The driving force behind assisted suicide is, in large part, the failure of the medical system and some of its practitioners to deal caringly and compassionately with the dying. "Kevorkian is a symptom of a medical care system gone seriously wrong at the end of life," wrote George J. Annas, professor of health law at Boston University, recently in the New England Journal of Medicine. 1

"What's going on here is not that everyone in the U.S. wants to commit suicide," agrees Christine K. Cassel, chief of Internal Medicine at the University of Chicago Medical Center [and president of the American College of Physicians]. "What's going on is that people don't trust us anymore to take care of them when they're dying." 2

W i t h good reason. Sometimes treatment is worse than its absence, and patients become trapped in medical hell. Susan Cahill, a former I C U nurse, looking back, now says, In the name of life support, I did things that were much worse [than euthanasia], things I can't forget and for which I still can't for90

Suicide and Attempted Suicide • 91 give myself. I wonder at the irony of it all: that they arrested Kervorkian for helping his patients find relief in death but not me for tormenting my patients as they declined and d i e d . . . . Most of the time, these patients were too far gone to communicate, but one woman managed to write "Let me die" on a piece of paper. I didn't let her; I wasn't allowed to.... I used . . . high-tech tools on people who everyone knew couldn't be helped by them and who didn't want them used and asked to have them stopped. But I didn't stop. I helped prolong the agony of these patients' d e a t h s — I knew that that was what I was doing. I did this often, sometimes every day, and I did it with the blessing of the medical community and the law... .The continuing debate over Kevorkian seems ludicrous. The people who sought him out were fully informed about the consequence of their "treatment," unlike many of the people who became entrapped in the high-tech world of life support gone wrong. Too often I worked with patients who never had explained to them what the real repercussions of their treatments might be, even when such discussions weren't precluded by urgency. W h y didn't someone arrest the health care professionals whose patients ended up strapped down and pierced with needles and tubes they didn't want? 3

Let's look at one case, one man, one family.

Earl Blaisdell, fifty-seven, had multiple sclerosis for eleven years. MS is a degenerative disease with no known cause or cure. It produces "multiple" lesions in the myelin sheath surrounding nerves, which interferes with the normal transmission of nerve impulses. Depending on the severity and location of the damage, symptoms may include: muscle weakness, spasm, or paralysis; pain; visual impairment; loss of bladder, bowel, and sexual function. Some cases are mild. His was not. "He was in absolute agony from this," said John Richert, director of the Multiple Sclerosis Center at Georgetown University Medical Center. "We were grasping at straws." a

After losing bladder control, a catheter was inserted, leaving him prey to

recurrent infection. A few months later his large intestine was removed; waste products exited through a tube in his abdomen into a bag. Eventually, all he could move were his face, neck, and, to some degree, left hand. His muscles were so inflexible that it took one person to straighten and hold his legs while another person washed him. He brought up the topic of killing himself and said to his wife of twentythree years, Carmi, "If I could lay my hands on a gun, this would be all over." She was horrified and lied that his life insurance policy had a suicide exclusion. He asked at least three people in one week to bring him a bottle of aspirin. They refused and told Carmi. As a result, his medicines were kept in another room and doled out to him; he was not permitted glassware, or use of non-battery-powered electrical appliances. He tried to reach Dr. Jack Kevorkian by telephone, but was unsuccessful. He asked for suicide help from his physician, Dr. William Benjamin III, who declined on "ethical" grounds, saying later, "I personally could not do it." On May 21,1994, Earl Blaisdell told Carmi, "I want you to know that I've just eaten my last meal." He had decided to starve himself to death. She tried to talk, cajole, and threaten him out of it. He was adamant. She cooked his favorite foods; he wouldn't touch them. Other family and friends tried as well, with similar results. "The dog ate very well," their daughter recalled. Blaisdell thought he would die in a week. He received last rites on day twelve, but his pain-racked body kept going. Finally, he died. It took forty days. He left a tape recording that he had secretly made two months before his death. In it he said, "I know you folks are trying to convince me that I should stay alive. But if you were layin' in this bed like this, you wouldn't do it either. . . . If I can find a way to get out of here, I'm going to try to find i t . . . . Don't feel bad about me being gone. I'm plain better off." A year and a half later, his family still had mixed and contradictory feelings about his death. "I miss him," says his thirty-five-year-old stepson, Michael. "I respected his choice, but I don't respect the way he died . . . he did it with strength, and a lot of will, but he took the coward's way out. . . . [I'm left with] the guilt—that somehow [I] could have done something to make life more meaningful to him so he wouldn't have felt he had to do what he did."

Suicide and Attempted Suicide • 93 A few months later the family's old dog was "put to sleep." "We had him fifteen years," Carmi mused. "I said to myself: It took Brandy forty-five seconds to die. It took Earl forty days of starvation."

PAIN CONTROL AND HOSPICE CARE

A long illness seems to be placed between life and death, in order to make death a comfort both to those who die and to those who remain. —Jean de La Bruyere (1645-1696) Death is a punishment to some, to others a gift, and to many a favor —Seneca

PAIN CONTROL Opponents of assisted suicide assert that almost all dying patients can be kept pain-free. Some hospice physicians go further, arguing that any failure in pain control is due to lack of knowledge on the part of the physician. Hospice physician David Cundiff says, "We have the knowledge and the means to assure that no terminally i l l person need beg for death to end his or her suffering. Those patients who have asked me for assisted suicide or euthanasia have changed their minds once I took care of their symptoms." Proponents of this view are certainly partly right. Pain control is inadequately and incompetently handled by many American physicians: Almost half of cancer patients receive inadequate pain medication, while 81 percent 1

Suicide and Attempted Suicide • 95 of nurses surveyed agreed that "the most common form of narcotic abuse in caring for dying patients is undertreatment of pain." The problem is similar elsewhere. From Germany: "The majority of cancer patients . . . are not treated for pain at all, and that those patients who receive treatment are treated inadequately." From France: "In the light of the high prevalence and the severity of pain among patients with cancer, the assessment and treatment of cancer pain in France remain inadequate, emphasizing the need for changes in patient care." From Australia: "One-third of patients with terminal cancer in a general teaching hospital received inadequate pain relief; the reasons for this included lack of medical expertise in the use of analgesics for chronic cancer pain." From Sweden: "About 30 percent of physicians believe that all patients have moderate to severe pain at the time of their death. Up to 78 percent of physicians and nurses believe that periodic severe pain is common in terminal cancer patients. . . . More than 50 percent of physicians and nurses admit that they have inadequate knowledge about pain evaluation techniques, newer analgesics and newer drug delivery systems." A large American study recently found that 42 percent of cancer patients were given inadequate pain medication. Women, minorities, and people over seventy fared worst. The reasons for this are complex and debatable. In my opinion, they center on power, fear, and ignorance. First, physicians have the power to dispense or withhold pain medications and they are loath to surrender it, particularly to the least powerful of their patients. Second, they are on far safer legal ground if they undermedicate rather than overmedicate a patient. If a patient dies in agony there will be no consequences to the doctor, but if the patient uses prescribed pain medication to commit suicide, there may be legal or professional repercussions. Third, most physicians' knowledge of pain control is inadequate. In a study of medical texts on the care of cancer patients, only twenty out of five-thousand pages mentioned pain control, and until 1995, there were no questions on pain control on cancer-treatment specialty certification board exams. A n d just five out of 126 American medical schools offer a course in care of the dying. Fourth, ambiguous and sometimes contradictory state and federal prescribing regulations adversely affect treatment decisions. For example, the Medical Disciplinary Board of Washington State made the following policy statement 3

96 • Geo Stone in 1985: "The Board does not recognize repeated prescribing of controlled substances as appropriate therapy for chronic pain." One might reasonably ask just what they would recommend instead. The board subsequently modified its position, but not before adding to the difficulties and uncertainties for physicians, who become understandably hesitant to prescribe narcotics in higher-than-normal dosage even when it's the only way to relieve severe pain. : Finally, the exaggerated fear of narcotic addiction, despite evidence to the contrary, is nowhere more irrational than with dying patients. Yet it continues to play a large part in pain medication decisions in the minds of legislators, physicians, and patients. 12

13

14

In the words of one cancer specialist, C . S. H i l l , "Despite . . . the availability of appropriate opioid analgesics, inadequate pain management of cancer patients remains pervasive." 15

The methods used by boards/agencies to determine standards of practice for opioid use result in interpreting the language in these regulations based on myths, prejudices, and misinformation about opioids, and the unexamined belief that mere exposure of patients to these drugs causes psychological dependence (addiction) on them to all patients in all instances. Interpretation is also strongly influenced by a failure of regulatory and enforcement bodies to recognize their coequal obligation of making opioids readily available to those who need them for legitimate medical purposes, while simultaneously policing their diversion to illegitimate uses. 16

While this problem is worldwide, there has been some progress. For example, in Norway administration of morphine to cancer patients increased twelvefold (per patient) between 1983 and 1990. Even so, examiners found that "several Norwegian hospitals still lag behind in this respect. Consequently much pain remains unrelieved." This is a truly bizarre situation: every study I've seen finds pain seriously undertreated; every expert recommends more use of pain medications. Yet the problem persists. Thus, Dr. Cundiff believes, with considerable justification, "We don't need a law to legalize assisted suicide, we need a law to teach doctors how to treat pain." 17

18

Suicide and Attempted Suicide • 97

HOSPICE AND SUICIDE Partially as a result of this belief, hospice organizations are adamantly opposed to assisted suicide and euthanasia. In 1991 the National Hospice O r ganization stated that it " . . . rejects the practice of voluntary euthanasia and assisted suicide in the care of the terminally i l l . . . [while]... championing] the ideals of relief of suffering, freedom of choice,"—as long as one of the choices is not suicide, assisted suicide, or euthanasia—"and death with dignity."

19

But one of the results of this attitude is that a patient considering suicide may be unwilling to talk about it with hospice workers—the very people who might be in the best position to tell the patient about better alternatives. Lonny Shavelson quotes a hospice nurse: We are instructed that if a hospice patient has a firm plan for suicide, we absolutely must intervene. This results at least in taking away medicines that he might use for an overdose, or hospitalizing the patient against his wishes and getting him psychiatric h e l p . . . . N o w let's face reality. N o t everybody can have the death that we read about in a hospice textbook .. . W e are great at helping almost everybody along, both physically and emotionally, but we just can't fix everybody. 20

A n d , whose decision should it be? Is there only one morally correct way to die? One dying patient's acerbic response to this hospice policy went to the heart of the matter: "If they don't approve of suicide, they don't have to kill themselves." 21

Nor do all hospice doctors agree. Dr. Timothy Q u i l l observes, Those who have witnessed difficult deaths of patients on hospice programs are not reassured by the glib assertion that we al-

98 • G e o Stone

22

ways know how to make death tolerable. .. .The simplistic ethical rule that a doctor may not intentionally aid a patient's death falls apart in real clinical situations; it may inhibit prescribing sufficient pain-relieving medicine when a patient is near death, even if the patient is in agony.

23

Reacting to the public debate following a recent assisted suicide carried out by Dr. Quill, a New York State Task Force on "Life and the Law" recommended "comfort care," which emphasizes relieving symptoms and enhancing the patient's quality of life, as the appropriate treatment for terminal patients. Dr. Q u i l l agrees, up to a point: 24

Comfort care is a far cry from "not doing anything." It is completely analogous to intensive medical care, only in this circumstance the care is directed toward the person and his or her suffering, not the disease. Dying patients need our commitment to creatively problem-solve and support them no matter where their 25

illness may g o .... [but] to think that people do not suffer in the process of dying is an illusion.... I am deeply troubled by our profession's unwillingness to openly acknowledge its limitations. 26

Ira Byock, another member of the Academy of Hospice Physicians, offers a different perspective: Dying is not simply suffering to be avoided. Once pain is skillfully controlled, most of our patients experience a surprisingly high degree of quality of life and see this time as a very precious time for them and their families.That is something I hear daily. 27

He concedes that pain control fails with some patients, but suggests placing such people under general anesthesia until they die. It's not entirely clear what the point is. The permanently unconscious patient derives no benefit from being "alive." Indeed, it is ironic that, with permanent anesthesia, Byock is advocating the functional equivalent (to the patient) of euthanasia.

Suicide and Attempted Suicide • 99 Under these circumstances, when death is imminent and inevitable, why must life be prolonged? Dr. Byock feels that the family should help care for their comatose relative: [l]n the turning and washing . . . family members are called to honor the person departing .. .this type of continuing care is a mature, balanced expression for the inner turmoil—the grief—that we may feel. 28

But, as one hospice nurse observes, ". . . harsh as it sounds, some families simply do not want to be caregivers. They do not relish the thought of weeks/months of bedbaths, pureed foods, and incontinence care. 'If I had wanted to be a nurse, I would have become one,' they tell me, and they mean it." 29

A 1990 National Hospice Organization resolution says, Family members can often use this final period of peaceful pharmacologically-induced sleep to begin to separate from their loved one in preparation for the time of actual death.... [this] is less of a burden to the family and the caregivers than having to directly cause death as the only way to relieve the patient's suffering. 30

While this may be true for some, it seems equally plausible that a chosen time of death provides the best opportunity for reconciliation, last words, and good-byes. I would not presume to decide this for you. ADDITIONAL PROBLEMS IN HOSPICE CARE

One of the problems with hospice care is that many people start it too late to get much benefit from it. Even though Medicare and most health insurance plans cover some form of hospice care for up to six months, the average survival time was less than one-fifth of that, 36 days; and one-sixth of the patients died within a week. Part of this simply reflects the uncertainties of prognosis: 15 percent lived longer than 6 months, 8 percent longer 31

100 • Geo Stone than a year; but some of the lateness of hospice care is probably because neither patients nor doctors want to concede that a case is really terminal. There are also legal problems due to the way many health insurance plans define "acute care": they will only pay for treatment intended to "cure." As a result, most (U.S.) hospice patients are treated at home—which requires someone else to live there and act as the primary caregiver. For similar legalistic reasons, people in hospital-based hospice are much more likely to receive unwanted "care" and resuscitation than those in home-hospice. For example, hospital-hospice will routinely treat pneumonia—including by traumatic intubation—and thus allow terminal patients to die of their underlying illness, say metastatic cancer.

LIMITS OF PAIN MANAGEMENT Few people, on either side of this issue, would disagree with the principle or desirability of hospice or comfort care, but it is naive to imagine that all patients can be made comfortable through better pain management. Some medical conditions generate pain that has proven to be resistant to control (short of sedation-to-unconsciousness). These include cancers that have invaded bone tissue, and elevated intracranial pressure. Side effects of high-dosage pain medication may include severe nausea, vomiting, inability to concentrate, nightmares, dizziness, or constipation. Nor is the relief of pain the same as the relief of suffering. Loss of physical or mental abilities, loss of friends, loss of a spouse, loss of interest in living, are all forms of suffering that pain medication won't help. What should be done when comfort care no longer works, suffering becomes unbearable, and a longed-for death is the only escape? 32

In Dr. Quill's words, None of these [dying patients] would want to die under other circumstances. But some reach the point where they would rather die than continue to live under the conditions imposed by their illness. We currently acknowledge this choice under some circumstances, for example when the patient rationally decides to stop a life-sustaining treatment like renal dialysis because of the burdens

Suicide and Attempted Suicide •101 of the illness and its treatments. Yet if there are no such treatments to stop, we do not allow other patients the same choice, even in the face of overwhelming and irreversible suffering. 33

Even with satisfactory pain management, some dying patients choose suicide. But there are pitfalls, as we see in data from Compassion in Dying, a Washington State-based organization that counsels and aids terminal patients. In their first 13 months, Compassion was contacted by 300 people who wanted help in dying. Forty-six met Compassions, rather restrictive criteria (and died during this time). Twenty-two had cancer, 16 A I D S , 5 neurological diseases (MS [multiple sclerosis], A L S [amyotrophic lateral sclerosis]), and 3 lung diseases. Each of these people was terminally i l l and confined to bed or chair. Pain was adequately controlled in all cases, and was not the primary reason for suicide in any patient. Nine were in institutions (hospital, hospice, or nursing home) and unable to acquire drugs for suicide. Four of these people starved themselves to death. The other 37 died at home. In 8 cases their physician would not prescribe a lethal drug. Three of these people killed themselves, two by starvation, one by gunshot; the other five died of their illness. Of the 29 cases where their doctor did write a prescription for a lethal drug, five people died without using their prescription; the other 24 died from deliberate drug overdose. These drugs were barbiturates, narcotics, and/or benzodiazepines. Time-to-death averaged three hours and ranged from 25 minutes to 10 hours (a later patient survived 24.5 hours). Thus, for those people confined to an institution or with a physician unwilling to prescribe a lethal quantity of drugs, the fraction achieving a chosen and relatively untraumatic death was low. Of those at home and having a cooperative doctor, none died of starvation—which took between 10 and 24 days in the people who used this means—or violent methods.

12 ADVANCE DIRECTIVES: LIVING WILL, POWER OF ATTORNEY FOR MEDICAL DECISIONS, AND DO NOT RESUSCITATE ORDERS

"If I ever get that way, shoot me," my uncle said after my father died in the hospital, hooked up to tubes and a respirator; pumped full of drugs, even though his brain was destroyed.The father we loved was gone, felled by a sudden heart attack. Yet he lingered a week in intensive care, a human vegetable covered by Medicare. In the end, all of us in the family were victims of the American Way of Dying. —Abigail Trafford

LEGAL ASPECTS—OVERVIEW Many people have heard of living wills, powers-of-attorney, and Do Not Resuscitate orders (collectively called "advance directives"), but most folks are unclear about their features and differences. Living will or "Natural Death Act Declaration": a document that allows you to specify, in advance and in writing, what medical procedures you want and don't want, should you become unable to make those decisions. A living will is valid only if you are terminally ill and incapable of making decisions. a

103

104 • Geo Stone Poiuer-of-attorney: a document giving to someone you choose the authority to make medical decisions for you—treatment, no treatment, or what treatment—valid only if you are unable to make such decisions. You do not have to be terminally i l l for this to take effect. Emergency Medical System (EMS) Do Not Resuscitate (DNR) order: a document, valid in about half the states, that prohibits emergency medical technicians from attempting to resuscitate you if your heart stops or you stop breathing. This is usually, but not always, limited to terminal patients. There are also in-hospital D N R s , valid in every state, that direct the medical staff to not try resuscitation in case your heart or breathing stops. There seem to be two driving forces behind the increasing public interest in, and use of, advance directives. First, I think, is fear of powerlessness in end-of-life situations, which might result in days or weeks or even years of hopeless "treatment." Second, is the concept of "responsible dying": that we owe it to ourselves, our families, and our society to accept responsibility for making end-of-life decisions. While most people are in favor of advance directives, only about 20 percent actually have them; most of us prefer putting off unpleasant decisions. 1

W h e n the subject comes up, the language is vague ... what [Dr. Joanne] Lynn calls the "I don't want to end up like Aunt Esther" remark. Everyone nods in agreement, but the details of what happened to Aunt Esther and why, get buried, as the cultural mechanism of denial kicks in and the family moves on to more pleasant subjects. 3

Be aware that if you don't specify otherwise, hospital physicians will use the full arsenal of life-sustaining equipment and procedures. A n d , once you start down this road, it is difficult to stop (another version of the slippery-slope argument) because procedures tend to require more procedures to limit and correct the initial ones. In addition, you will probably not be in the best condition to make good decisions: severely i l l and either sedated or in pain. However, doing nothing is also a choice and has consequences. If you don't make these decisions—and too often if you do—someone else, often a family member but perhaps a stranger, will make them for you. "The tough-

est cases are when someone rolls into the intensive care unit, and we have no idea what they want," said Thomas Rainey, director of critical care medicine at Fairfax (Virginia) Hospital. "We will always err on the side of saving life, but those efforts are often brutal." 4

Awareness of the limitations of advance directives is critical. First, it's important to understand that these documents are in effect only while you are incapacitated. If, and as long as, you are alert and coherent a living will and power-of-attorney are not in force; it doesn't matter what they say or don't say. Your physician is, in fact, forbidden to act on them. Decisions are (supposed to be) made by you, preferably in consultation with doctor, family, and friends. You don't need to be able to speak as long as you can communicate your coherence and intent. Second, advance directives cannot be used to request or receive "active" help in dying. They merely allow you to die without further medical intervention. Thus they will not be useful in ending a terminal illness; at best they will just prevent the process from being artificially extended. This sounds quite straightforward, but in the real world, many hospital patients are somewhere between mentally competent and incapacitated. In addition, the physician usually has the monopoly on medical knowledge and here, as elsewhere, knowledge is power. Looking at things from the other side, while "patient empowerment" through advance directives and "informed consent" may be ethically necessary, it also leaves life-and-death decisions in the hands of people who are, often, both debilitated and medically ignorant. A conscientious physician will thus spend much time explaining the medical situation.

LIVING WILL—DETAILS

A living will is a limited document and has serious shortcomings. It specifies what medical treatment you want if you become unable to convey your wishes; for example, whether or not you want attempts made to extend your life by procedures such as C P R . Again, in most states, a living will only applies if you are terminally ill and unable to make decisions. Thus, it would not apply in many circumstances, such as if someone were brought into the I C U after a stroke. This is probably a reasonable restriction on living wills since

106 • G e o S t o n e

there are so many variables and uncertainties in emergency medical decisions that can't be predicted in advance; but it also means that someone who has specified that he does not want intervention will, under many circumstances, likely receive it anyway. There are two styles of living wills. One describes a person's treatment goals and philosophy; the other is a checklist of medical conditions. An example of the first style, if you don't want heroic, or life-extending procedures (if you do, you should make that preference clear) might be something like, If I'm terminally ill, in a persistent coma, or permanently demented, I want to die as quickly and comfortably as possible. In such circumstances, I hereby decline any and all life-extending measures, including artificial nutrition and/or hydration, and accept only such treatment as is intended to make me comfortable ... The checklist version attempts to designate the desired level of treatment for a wide range of medical conditions: (1) do everything possible; (2) do conservative care (for example, antibiotics) but no extraordinary measures (for example, C P R ) ; (3) do comfort care only. The advantage of this approach is that it specifies what you would want done in a particular described situation; the disadvantage is that there are many more circumstances than one can possibly anticipate. In addition, it requires an unrealistically high level of knowledge of diseases, treatments, and consequences. Timothy Q u i l l suggests that "patients . . . specify their treatment goals and objectives under circumstances commonly associated with incompetence, including, but not necessarily restricted to, irreversible dementia, terminal illness, and persistent vegetative state," as opposed to using the checklist form. 5

This approach avoids Scilla, but often runs into Charybdis: A sufficiently general document may be too vague to guide a doctor, particularly one who is unfamiliar with the patient, as is frequently the case in big-city and teaching hospitals. It will almost always help to have a personal physician, with whom you have discussed these issues. While there have been lawsuits by families wanting to let a dying relative expire, the courts have generally allowed this only when the individual has

Suicide and Attempted Suicide • 107 made such a living will. There have been some exceptions (see discussion of Quinlan and Cruzan, below), but only in extraordinary circumstances.

LEGAL ASPECTS—CASE LAW

Karen Quinlan suffered extensive brain damage in 1975. Eventually her parents, acting to exercise her right to refuse treatment, decided that lifesupport should be ended. Her doctors, though stating that her condition was permanent, refused and a court case ensued. The New Jersey Supreme Court sided with the parents and Karen Quinlan's respirator was removed. However, the nuns at her hospital, anticipating and disagreeing with the decision, had weaned her off the respirator, and she continued breathing on her own, surviving until 1985. During most of those ten years she was "a comatose eighty-pound figure, curled in a fetal position and kept alive by intravenous feeding . . . completely unaware of the outside world." Her parents did not, apparently, try to have the IV food and water ended. 6

The legal significance of the case is that it is the first time the courts found a constitutional right to privacy to be the basis on which an individual could make medical care decisions, including withdrawal of treatment. This was extended to withdrawal of treatment by a conscious, competent individual— with a quickly fatal illness—in Satz v. Perlmutter (Florida, 1978). The first of these cases to reach the U.S. Supreme Court started in 1983. In that year twenty-five-year-old Nancy Cruzan suffered severe and irreversible brain damage as a result of a car wreck. She lost control of her car on a country road, was thrown out, and landed facedown in a water-filled ditch. By the time she was pulled out, she had, essentially, drowned. Enough of her brain stem remained functional to allow her to breathe without a respirator, but she was in a coma, had no swallowing reflex, and had to be fed and watered through a surgically implanted feeding tube in her stomach. When Nancy showed no signs of improvement after four years, her parents accepted that she would not recover, and asked that the feeding tube be removed. 7

In Cruzan v. Director, Missouri Department of Health, 497 U S . 261 (1990), the court ruled that while refusing treatment was each competent individual's right, a state could restrict the right of surrogates, in this case Nancy

108 • G e o S t o n e

Cruzan's parents, to make such decisions for an incompetent person and that the burden was on the Cruzans "to prove unequivocally that she would not want to be treated." This burden of proof is a strong argument in favor of having a living will and a power-of-attorney for health care document, because, i f you don't specify otherwise, the state will insist on continuing treatment, however hopeless. Conveniently, some of Nancy Cruzan's friends remembered that she had told them that she would not want to be kept alive under such circumstances. This tipped the scales of proof and, in 1990, after almost eight years of vegetative maintenance (at around $130,000 per year) a Missouri court agreed to the feeding tube removal; this was done on December 14, 1990, but opponents invaded the hospital in order to reattach the apparatus and threatened to kidnap Cruzan. These attempts failed, but Nancy Cruzan survived for another twelve days, dying slowly of dehydration. "Nancy's lips dried and blistered. Her tongue grew sticky and swollen, and her eyelids dried and began to stick shut." Of course, if someone, perhaps outraged by this totally senseless suffering, had done anything to end it— say, injecting a lethal drug—this would have been murder under the laws of every state. On her tombstone is written: 8

The significance of these cases (and the more recent Quill v. Vacco and Compassion in Dying v. State of Washington (1997) is that (1) the current conservative U.S. Supreme Court, while reluctantly recognizing a right to privacy, is unwilling to extend it any further than precedent requires, if that far; (2) state court decisions are all over the map: the Missouri Supreme Court (Cruzan) found a compelling state interest and required "clear and convincing proof" that withdrawal of life-support was what the permanently co-

Suicide and Attempted Suicide • 109 matose patient wanted. Meanwhile, the New Jersey Supreme Court (Quinlan) reached the opposite conclusion, stating, "We have no hesitancy in deciding . . . that no external compelling interest of the State could compel Karen [Quinlan] to endure the unendurable, only to vegetate a few measurable months with no realistic possibility of returning to any semblance of cognitive or sapient life" (In re Quinlan, 1976, 39). In Great Britain, a less individualistic society with socialized medical care, a different standard is used. Under comparable circumstances to Cruzan or Quinlan, British judges have come to ask: "What is in the best interests of the patient?" rather than "What did the patient want?" Thus an appeals court judge said, "Looking at the matter as objectively as I can, and doing my best to look at the matter through M r . Bland's [a permanently vegetative patient who had been crushed in a crowd during a soccer match] eyes and not my own, I cannot conceive what benefit his continued existence could be thought to give him." The British judges also seem to be a good deal more honest about what they're doing. In the same case, another judge said, "The whole purpose of stopping artificial feeding is to bring about the death of Anthony Bland." The initial ruling, the appeal, and the final appeal to the House of Lords were all unanimous decisions in favor of ceasing maintenance for M r . Bland. The British courts are not yet willing to permit active euthanasia, but they are becoming increasingly uncomfortable with the contradictions in their position. In the words of another of the House of Lords judges, 11

12

Finally, the conclusion I have reached will appear to some to be almost irrational. H o w can it be lawful to allow a patient to die slowly, though painlessly [perhaps true in the Bland case, but often not], over a period of weeks from lack of food but unlawful to produce his immediate death by a lethal injection, thereby saving his family from yet another ordeal to add to the tragedy that has already struck them? I find it difficult to find a moral answer to that question. But it is undoubtedly the law and nothing I have said casts doubt on the proposition that the doing of a positive act with the intention of ending life is and remains murder 13

110 • G e o S t o n e

It is an interesting distinction that turning off a respirator or removing a feeding tube is not a "positive act," while administering an injection is. I find these actions morally equal; and if the first is justified, so is the second. Often, the opposite situation arises: The family insists on futile treatments, despite the wishes of the medical staff. In one case an eighty-sevenyear-old woman in an irreversible coma was kept on a respirator for a year-and-a-half (at a cost of almost a million dollars). Her physicians went to court for permission to disconnect her life-support. 14

15

This case gets more complex when you try to balance several sometimescompeting interests and issues: (1) What is in the best interests of the patient? (2) What did the patient want? (3) What does the family want? (4) Is there an unlimited right to medical treatment? In this instance, the medical staff determined that Helga Wanglie was in a persistent vegetative state and that to continue artificial respiration was both futile and not in her interest. However, the patient, according to her family, did not want her life "snuffed out." The Minnesota court ruled that the patient's alleged desire for treatment had priority over the medical judgment that it was useless. I don't know if they (or other courts) have addressed where the limits to the implementation of those desires lie. While I support the right of a person to refuse treatment, does this compel my similar support of a right to require treatment? I think not; certainly not without bounds and not under every circumstance. In the real world of limited medical resources, I find it insane to spend a million dollars to maintain the body of a brain-dead eighty-seven-year-old. These are often, however, not easy decisions to make: b

Withdrawing treatment from someone who might recover fully is excruciating every time. Watching the prolonged suffering of someone who has very little chance of "making it" is similarly excruciating . . . [but sometimes] the situation forces a choice between these two options and we temporize briefly hoping for more clarity. 16

POWER OF ATTORNEY—DETAILS

A more flexible and less restrictive document is the power-of-attorney for health care, or health-care proxy. Like a living will, this only comes into effect if and while you are incapacitated, but is not limited to terminal conditions. Rather than specifying the response to an unknown future medical crisis, it gives, to someone you choose, the power to make health-care decisions on your behalf. This includes the decision to accept or withhold treatment, so it is absolutely necessary to have someone who understands what you want—and don't want—preferably agrees with it, and who is tough enough to insist that your wishes be carried out. The primary reason such a power-of-attorney is useful is that it is impossible to anticipate all possible medical circumstances in a living will, no matter how detailed. A health-care proxy provides the flexibility to make decisions, consistent with what you want, in unexpected situations. It is i m portant to have both a living will and a power-of-attorney document, since some states will not permit actions, such as removal of feeding tubes, based on the proxy's understanding of what the patient would have wanted. They require corroborating evidence. Thus, language stating your refusal to accept artificial feeding and water (if that's what you want) should be included in both documents. This is a new and fuzzy area of law. For example, what happens if there is a conflict between a living will and the health-care proxy's decision? The more detail you specify about what you want and don't want in a living will, the less basis the courts have to interfere, but the less flexibility a health-care proxy will have as well. In light of this, Timothy Quill recommends writing the living will as a general description of goals, as described a few paragraphs ago, and giving the health-care proxy—if it's someone you can rely on— room to respond to the situation at hand, within those guidelines. Even so, it may not be enough. In one case, poet and editor Brenda H e witt had a living will and a health-care proxy she trusted. "The proxy arrived at the hospital with her. But he was ignored, pushed aside, and threatened by staff members as he tried repeatedly to act according to the patient's instructions and prevent the aggressive medical interventions she had feared all along." A n d , according to health law professor George Annas, the 17

treatment received by Brenda Hewitt and her proxy is "a cruelly common occurrence . In another instance a dying hospital patient, a surgeon, told his son, who was his health-care proxy and also a physician, "Norman, I have been a surgeon for almost fifty years. In that time I have seen physicians torture dying patients in vain attempts to prolong life. I have taken care of you most of your life. Now I must ask for your help. Don't let them abuse me. No surgery, no chemotherapy." These instructions were ignored; the father was subjected to a series of useless, unnecessary—and billable—procedures and operations despite his express instructions and those of his son. The intervention of another son, a lawyer, was equally unsuccessful in stopping the events. The tab came to $150,000 for a man who "needed only a bed and some morphine." Afterward, the younger Dr. Paradis wrote, "If a doctor and a lawyer could not get decent care for a doctor, what chance does the public have?" 18

Do NOT RESUSCITATE (DNR)

ORDER—DETAILS

Yet a third document is needed to keep the rescue squad medics from doing C P R and otherwise trying to revive you even if you are terminally i l l , incapacitated, and have a living will that says that you do not want such treatment. This one is called an Emergency Medical System (EMS) do not resuscitate ( D N R ) order. Twenty-four states have implemented these (as of December 1994) in response to the usual horror stories. In one typical case, a seventy-seven-year-old Washington, D . C . , man died at home with his family at his side as he had wanted. W h e n he stopped breathing, the family called the police nonemergency number to inform city officials of his death. A few minutes later a firefighting team— remember, this is Washington—showed up, entered, and began trying to resuscitate him. "I heard my mother screaming at the top of her lungs, 'What are you doing? What are you doing?'" said the man's son, who said firefighters ignored a living will the family showed them. "It was a night21

mare." E M S D N R s can be issued, by their doctors, to terminal patients whose death is impending and who want to die at home, or at a nursing home or

Suicide and Attempted Suicide • 113 hospice, rather than in a hospital. Some states do not require the death to be imminent; a few states do not require terminal illness at all. Since in most emergencies there is little time to look for D N R documents, a few states (and counties) permit D N R bracelets. Where there is an E M S do not resuscitate order, emergency personnel are not supposed to perform C P R if the patient's heart or breathing has stopped. But they will treat other problems they find. Thus i f a D N R patient falls and hits her head, she will be treated for that. "We've had very positive experience with this," said Nancy Taylor, director of a hospice organization in the Washington, D . C . , area. "It comes as a relief to most people to have this option." A l l fifty states and the District of Columbia have some form of advance directives, but the state laws differ in crucial details and don't honor one another's documents; so check in your jurisdiction—and don't get sick while traveling. Choice in Dying, a New York-based organization that promotes patients' rights, will provide you with the appropriate state forms. You can get a copy (via the Internet: http://www.choices.org; or $3.50 by mail), or get more information by calling them at 1-800-989-WILL. A lawyer is not needed to write an advance directive. E M S do not resuscitate orders of one sort or another are (as of M a y 1994) legal in Arizona, Colorado, Florida, Georgia, Illinois, Maryland, Montana, New Mexico, New York, Pennsylvania, Rhode Island, Tennessee, Utah, V i r ginia, Washington, West Virginia, and Wyoming, according to Choice in Dying. Any of these documents can be revoked or changed at any time by a legally competent patient. A do not resuscitate order can also be canceled by the holder of the power-of-attorney. That's the good news about advance d i rectives. The bad news is that often a living will and power-of-attorney are useless.

LIMITATIONS AND FAILURES OF ADVANCE DIRECTIVES A lack of advanced directives in the face of lost [mental] capacity is the most frequent cause of inhumane overtreatment. . . .The apparent reluctance of physicians to discuss such

114 • G e o S t o n e

issues with their patients before capacity is lost is a cause of much unnecessary suffering. — S . J. Regan, hospital attorney 22

What we have here, is failure to communicate. —from Cool Hand Luke The evidence is clear that physicians and hospitals cannot be relied on to ask about the existence of, let alone honor, a living will and a power-of-attorney for health care. Still, these documents are better than nothing: A doctor who ignores a valid living will "may be held civilly liable for breach of contract, battery, and intentional infliction of emotional distress." 23

It must be noted that patients and their families share responsibility for the failure of these well-intentioned directives. They may be ambivalent. Their expectations may be unrealistic. They frequently wait until a medical emergency before trying to make these decisions. A n d most people do not make their best decisions under stress. In addition, there are all the pushes and pulls of family dynamics: W h o wants to live with the guilt of ordering their parent's respirator turned off? There are many times when it is the family that insists on carrying on, past the point where the physician would have stopped treatment that was hopeless. Sometimes a living will that specifies "no heroic measures" is ignored by the physician because he thinks he knows better—and sometimes he does. But more often, a doctor will carry out a family's demand to "do everything" possible despite living will instructions to the contrary. Why? Because they're a lot more likely to be sued for malpractice by a living family member than by a dead patient, even though forty-seven states (up to 1993) have passed legislation protecting doctors from lawsuits for failing to treat when the patient has executed a living will specifying withdrawal of treatment. A n d then there's the money. In the words of Dr. Sam Brody, the physician's thinking goes: 24

We've got to cover our asses or they will sue us or worse.The family wants anything done.... [Doctors] repeat this mantra of selfserving paranoia as we put our patients through paces that fre-

Suicide and Attempted Suicide • I 15 quently serve only our own interests.... I realize that if D N R meant " D o N o t Reimburse" instead of " D o N o t Resuscitate," far fewer of the terminally and hopelessly ill would receive pointless treatment. 25

On the other hand, what we hear about are the horror stories, the cases where patient and family want treatment to stop and are ignored, pressured, or intimidated by the physician. We don't hear about cases where the patient, doctor, and family agree, and act accordingly. Nevertheless, the bottom line on advance directives is that they don't seem to have worked very well. As Daniel Callahan, a specialist in medical ethics, noted, "It looked so easy . .. yet here we are, some twenty-five years at least after the introduction of the advance directive movement—the principal vehicle for implementing patient preferences . . . [still] trying to get straight about the last weeks and days of dying life." 26

WHY HAVE ADVANCE DIRECTIVES NOT WORKED BETTER? "I am eighty-two years old, and I don't want this done," the stillcompetent patient told the medical team. Like her voice, Harriet Shulan's living will, filed in another state, was useless when she was hospitalized in Arizona. So the "life-sustaining tubes were inserted up her nose and down her throat and into her arms." While she was too weak to refuse consent, major surgery was performed; her condition worsened and she was placed on a respirator while her continuing requests ("Please let me die") were disregarded because the hospital feared a lawsuit. W h e n she tried to remove the tubes herself, her hands were strapped to the bed. 27

The federal Patient Self-Determination Act, which took effect in 1991, requires, among other things, that a hospital inform patients of their right to refuse or accept treatment, and ask if an advance directive exists and note yes or no in the chart. 28

This is not reliably done. In one study, published in August 1995, of 114 cases where patients had written living wills and chosen another person to

116 • G e o S t o n e

make medical decisions for them by means of power-of-attorney, only 26 percent were noted in the patient's chart during their hospitalization. In the rest there was no indication that the medical staff had consulted either the living will or the designated health-care proxy before (or after) making medical decisions. There were no lack of reasons: Nursing homes failed to transfer the documents, patients did not volunteer the information, the chosen health-care proxies failed to be assertive, and the hospital staff failed to ask about advance directives or ensure that they were part of the patients' charts. Whatever the cause, the result was the same: Only in one of four cases of patients with advance directives was the physician even aware of the existence of such a document. Another study looked at the widely held notion that, despite shortcomings, advance directives encourage patients and doctors to discuss end-oflife issues. The findings, published in 1994, suggest otherwise. Two out of three patients who had advance directives never talked about these topics with their doctors. In this group of patients who had a living will or a powerof-attorney, 76 percent of their physicians thought they didn't or said they didn't know. In the authors' words, "We are struck by how infrequently these discussions are reported to have taken place, and it appears that physicians are for the most part unaware whether their patient has executed an advance directive." 29

What about people who were terminally ill? In one study, 2,600 dying patients, with life expectancies of less than six months, were asked if they wanted attempts made to resuscitate them if their hearts stopped. In only half the cases did the physician know what the patient wanted. In almost one-third of the cases, a patient's desire not to have C P R attempted was at odds with their doctor's perception of what the patient wanted. When the patient didn't want C P R , the doctor was right 47 percent of the time, wrong 30 percent, and unsure 23 percent; when the patient wanted C P R , the physician was right 57 percent of the time, wrong 17 and unsure 26. A n d this massive failure in communication doesn't even begin to address the issues that arise when the physician does understand what the patient wants, but disagrees with it. 30

Wait—it gets worse. From a large, multiyear study of nine thousand se-

Suicide and Attempted Suicide • 117 31

verely i l l patients in five hospitals, despite written and oral instructions to the contrary, many of these people suffered long and painful deaths because their doctors ignored or were unaware of their wishes, including those written into living wills. A Support study deserves further attention: Particularly since the Quinlan case, there has been a growing belief among physicians and medical ethicists that the best and most effective way to change the way we die is to arrange for better communication between doctors and patients. If both doctor and patient knew the prognosis, and understood the options, and if the doctor knew what the patient wanted—and didn't want—this would lead to better hospital care for the dying and fewer inappropriate "heroic" measures that merely prolong death. 0

The evidence shows otherwise. Not only was there amazingly poor communication between physicians, terminally i l l patients and their families, but the measures specifically designed to improve communication had no effect. As Dr. Joanne Lynn, a codirector of the project said, "We did what everyone thought would work and it didn't work at all." In one part of the study, patients were randomly divided into two groups. One received standard care, while the other got extra help. This assistance included providing their physicians with a daily computer-generated prognosis of survival time, probability of disability within two months, and the patient's wishes concerning treatment. Each patient was also assigned a specially trained nurse to be the patient's advocate and go-between, in order to facilitate communication between doctor and patient, to find out patient preferences, improve patient understanding of medical procedures and outcomes, and assist with pain-control problems. None of these steps had the slightest effect on four variables: (1) the time spent in a coma or hooked up to "assisted breathing" apparatus; (2) pain; (3) hospital costs; and (4) treatment decisions, such as do not resuscitate orders. "These data are astonishing," said Dr. Lynn. "No study comes up with findings this flat. . . . There's not even a wrinkle." The specific findings are grim. Of the dying patients: • 38 percent spent ten or more days in I C U in coma and/or on mechanical breathing apparatus before expiring.

118 • Geo Stone • 50 percent suffered moderate or severe pain during most of their last three days. • 31 percent of families lost most or all of their savings. • 70 percent of physicians did not discuss C P R with patient. • 50 percent of physicians did not write a do not resuscitate ( D N R ) order when patients wanted C P R withheld. The unequivocal failure of the additional measures to make any difference shocked the researchers. If I become old and develop a chronic illness—prostate cancer; say, or lung disease—I'm going to make sure I'm not whisked off to the hospital and put into the ICU and attached to technology.... I do not want to die in an ICU. I've seen too many cases where the patient is surrounded by so much technology and so many machines that the family can't even get in and hold their hand. . . . Dying is important. It's the last memory we leave with those we love. These are not the words of Jack Kevorkian; they are from the lead author of the JAMA study, William Knaus, who has spent most of his medical career working in and studying I C U s . Where does that leave the rest of us? 32

13 SOME PRACTICAL ISSUES IN ASSISTED SUICIDE

There is only one prospect worse than being chained to an intolerable existence:The nightmare of a botched attempt to end it. — A r t h u r Koestler' Facts do not cease to exist because they are ignored. —Aldous Huxley Friends help you move. Real friends help you move bodies. —Anonymous There are two related practical problems with assisted suicide: (1) In most places it's illegal; (2) in many cases the job is bungled. As a result, end-oflife discussion between patient and doctor is often inhibited: physicians fear prosecution; patients fear involuntary commitment and deprivation of pain medication. The result is, all too often, ill-informed decisions badly carried out.

LEGAL SITUATION AND CASES The legal situation is both murky and quirky: While committing or attempting to commit suicide is not illegal,* helping someone else to do so is. Quite bizarre, when you think about it. Philosopher James Rachels makes a 120

Suicide and Attempted Suicide • 121 logical argument for legalization of assisted suicide: "If it is permissible for a person (or if a person has the right) to do a certain action, or bring about a certain situation, then it is permissible for that person (he or she has the right) to enlist the freely given aid of someone else in doing the act or bringing about the situation, provided that this does not violate the rights of any third parties." 2

3

Nevertheless, assisting a suicide is illegal in most U.S. states and foreign countries, but is not necessarily a crime in Switzerland, Germany, Norway, Uruguay, the Netherlands, and Colombia. Some state laws have been challenged in court, generally without success, but only a small fraction of cases are ever prosecuted. One that was comes from Connecticut. In 1991 William Meyer, Jr., eighty-eight, died from asphyxia induced by securing a plastic bag over his head. He had colon cancer that had spread to his lungs. He had written, in letters to eighty people to be mailed upon his death, "I happily decided that it was more kind and thoughtful of me to terminate my life before I reached a decadent condition of helplessness." He told a friend of forty years, "I just don't want to continue to suffer. I've had five operations and now I need another and it's useless because I'm not going to get well." b

The police, called to his house by his sixty-five-year-old son, William Meyer III, decided it was a simple case of suicide. However, in August 1994, after several locally published interviews, a magazine in a nearby town printed the son's account of how he had helped his father kill himself. The police came back and arrested him. He was charged with second-degree manslaughter, which carries a ten-year prison sentence. In his first suicide attempt, the father had taken an overdose of medication and tied a plastic bag around his head with rubber bands. The elder M r . Meyer tore off the bag in an unconscious reflex. Though shaken by this failure, they decided to try again another day. This time the son would hold his father's hands, they agreed. A n d that's how it was done. "He kept reaching up. He kept trying to take the bag off.. . . He struggled for about five minutes." This suggests that they used the wrong drug(s), inadequate dosage, too small a bag, or put the bag on too soon. (See Asphyxia chapter.) 0

When the author of the Connecticut magazine article that attracted the au-

122 • G e o S t o n e

thorities' attention asked M r . Meyer why he wanted the public and the police to know what he had done, he replied, "Because I think it would be a good test case for the State of Connecticut.... I was so frustrated that there is still no answer for all these very anguished people who face painful deaths. . . . They need this issue raised." "People with terminal illness have a right to make a decision about the end of their lives," he said later. "As helpless as I felt in that jail is not nearly as helpless as those people feel forced to stay alive." On December 15, 1994, William Meyer III was sentenced to two years' probation. He also agreed to not help anyone else commit suicide, to donate $1,000 in his father's name to a prison youth program, and to drop his membership in the Hemlock Society. Kafka would have loved it. 5

When patients are close to death, there is a strong tendency on the part of most families, physicians, medical examiners, and police to "look the other way," and not examine the exact cause of death too closely unless their attention is specifically drawn to it. In one series of interviews, only fifteen of 140 non-physician-assisted suicides were even classified as suicides, and none were considered "assisted," though all, in fact, were. In many of these cases there was an active conspiracy on the part of the dying person and his or her doctor, family, partner, and friends: "In forty-one of these remaining 125 deaths, physicians knowingly provided lethal prescriptions, were fully aware of their patients' plans to end their lives, and signed their death certificates claiming 'natural' causes." 7

8

Without anything stronger than anecdotal evidence, my sense is that local prosecutors tend to be more hard-nosed, though it may be that we hear mostly of the ones who insist on following the letter of the law, unmodified by either compassion or sense. In the words of the prosecutor in the case of W i l l i a m Meyer, " M y decision [to prosecute] was based on whether there was probable cause that a crime was committed. Assisting in a suicide is a crime. The law is the law." A n d , as Dickens observed, a ass. In fairness, not all prosecutors are cut from the same cloth. For example, on M a y 20, 1994, California District Attorney Dennis Sheehy said that Dr. John Coe, who helped a dying A I D S patient commit suicide, would

This is an area where the concept of "jury nullification" is real: Although the evidence for such assisted suicide may be overwhelming, juries rarely convict under these circumstance, even if they have to ignore the judge's i n structions. One hundred fifty-one "mercy-killing" cases were tried between 1920 and 1985 (70 percent between 1980 and 1985). Only ten people were convicted of (or pled guilty to) homicide and jailed. Even with Dr. Kevorkian, who has rubbed their noses in it, prosecutors have failed to get a single juror in three trials to vote for conviction. 9

On the other hand, it is always possible to get some combination of ruthless prosecutor, incompetent defense attorney, unsympathetic jury, and hanging judge. On March 4,1985, seventy-six-year-old Roswell Gilbert was convicted of first-degree murder and sentenced to twenty-five years in prison—without parole—for shooting his wife of fifty-one years, who had Alzheimer's disease (progressive dementia, with no realistic hope for recovery) and osteoporosis (loss of bone strength, leading to multiple fractures and severe pain). He spent five-and-one-half years in jail before being granted "clemency" due to his age and poor health.

MEDICAL FAILURE IN ASSISTED SUICIDE AND EUTHANASIA

A much more likely problem is the failure of an assisted suicide to go smoothly. One of the few studies of assisted suicide looked at the situation among dying A I D S patients in Vancouver, British Columbia. Russel Ogden found that half of the thirty-four mostly non-physician-assisted suicides he was able to get details on were bungled, increasing suffering when the aim was to alleviate it. The assisted suicides were carried out by ministers, physicians, social workers, counselors, teachers, and writers. In six cases, death was from an overdose of barbiturates; in six others, morphine; in two more, heroin; five died from a combination of sedatives and plastic bag asphyxia; one died from a gunshot, one from a razor blade, one from carbon monoxide, and two from injection of an unknown material. Many of these people took several hours to die. In one case it took four days. "We injected him with massive amounts of morphine and he didn't 11

124 • Geo Stone die," said one of those who assisted in that death. "We used a month's supply of morphine in three days. We were triple-dosing him every hour because the information we had was that eventually the morphine would arrest his respiratory system." One physician felt that the law forced him to secretly kill dying A I D S patients with huge overdoses of their pain medication, morphine, rather than the much faster and more reliable secobarbital (Seconal). 12

Many of these deaths did not go as planned. In several cases pills were vomited before they could exert their full effects, leading the assistants to finish the job with plastic bags, gun, or razor blade. As one assistant said: At least I had an idea of what to do when he died. I had a vague understanding of what would happen and had the phone numbers of who to call. But I was totally unprepared for failure.This would mean that it would officially become a suicide attempt and could implicate the doctor who gave us the prescription. Plus, I didn't know if the overdose would cause serious damage when he recovered. I didn't want to see him in worse shape afterward than he'd been in before. 13

Ogden, a thirty-one-year-old social worker who spent thirteen months interviewing people, said, "What this study shows is that in the absence of regulation and medical supervision, euthanasia is occurring in horrific circumstances, like back-street abortions." He cited lack of knowledge on the part of the suicide assistants and lack of suitable drugs as the i m mediate problems, but the failure to legalize assisted suicide as the root cause. 14

The head of the British Columbia Persons with A I D S Society, A r n Schilder, said the report showed "only the tip of the iceberg." He added, "We have no alternative now to coat-hanger euthanasia." Based on Ogden's data and another study from the Netherlands, between 10 and 22 percent of A I D S deaths are from assisted suicides. Anecdotal evidence suggests that assisted suicide is particularly common in the gay A I D S community, especially in large cities. In general, there have not been legal repercussions. 15

Suicide and Attempted Suicide • 125

WHAT SUICIDE METHODS ARE MOST APPROPRIATE FOR A TERMINALLY III PERSON IN A HOSPITAL?

I believe that choosing if and how to end your life is your decision to make. On the other hand I also believe that suicide should not be undertaken without a clear medical prognosis and understanding of alternatives nor when in the midst of temporary or correctable depression. If you're thinking of killing yourself, are all of the following conditions true? If not, some other course of action is indicated. 6

1. You have advanced terminal illness and/or your "quality of life" is unacceptable (intractable pain, physical or mental disintegration, etc.) and without likelihood of improvement; 2. You're of sufficiently clear mind to make rational decisions; 3. You've discussed the diagnosis, situation, and treatment choices with your doctor and are sure that you understand them; 4. You have gotten an independent second opinion; 5. You've considered the alternatives (for example, hospice care, with generally better pain control than hospitals provide); 6. You're not "clinically depressed"; 7. You're consistent in your choice; 8. Your physician and family will not help you, or provide you the means, to kill yourself. Each situation differs, depending on your physical condition and abilities, how and how frequently you're monitored, and other variables that I can't anticipate. (Are you on the first floor or the tenth floor? Does your window open? Can you get out of bed?) In general, your best bet—if you're not continuously monitored—for a quick suicide under these circumstances will be some form of asphyxia: hanging (you don't need to be suspended) or strangulation. These methods take less than fifteen minutes and can be done without leaving bed. Plastic-bag asphyxia usually takes longer and is more prone to error, but may be combined with drug overdose. See chapters on asphyxia, drugs, and hanging for further information. Drug overdose, by itself, will almost always take too long, and overdose

126 • Geo Stone with pain medication will be less effective i f you've been using the drug therapeutically and have therefore developed some level of tolerance. For example, eighty-one-year-old Alice Marks, suffering from degenerative bone disease, injected herself with an overdose of morphine (one of her pain drugs) with the knowledge and in the presence of her son. Believing that she was dead, he called paramedics, who revived her. She was deprived of pain medication in the hospital and was subsequently transferred to a locked psychiatric ward as she was considered a "danger to herself." 17

If you have an intravenous line, you may consider potassium chloride, found in salt substitutes. This is the method that was used by Dr. Kevorkian in his first assisted suicide. Janet Adkins was a fifty-four-year-old woman diagnosed as being in the early stages of Alzheimer's. She could still converse and play tennis, but could no longer read. Knowing the grim progression of this disease, she chose to end her life while she was still able to arrange to do so. In June 1990, she went to Michigan, with her husband and three children, and met with Kevorkian. The next afternoon, with the support of her family, she reaffirmed her decision. Kevorkian started an IV line in her arm. When she was ready, she opened a switch that added a sedative to the IV drip and activated a timer that would add the potassium chloride. She soon fell asleep, and shortly afterward, her heart stopped. Electrocution and drowning are remote possibilities. (See respective chapters on these methods.) The most commonly reported method of suicide among hospital patients is jumping from a height, but the numbers are small (on the order of one per hospital per year, or two per 100,000 admissions) and, in addition to the medically i l l , they include "acutely delirious" admissions, and those admitted after a suicide attempt. f

Unfortunately, if you don't succeed at first, you may not have much chance to "try, try again." You will probably see access to medications restricted and may even find yourself in restraints—for your own good, of course.

14 EUTHANASIA IN THE NETHERLANDS

I am dying with the help of too many physicians.

—Alexander the Great

The two most prestigious American medical journals have recently addressed assisted suicide and euthanasia in the Netherlands. Citing the same evidence, they say: "From our point of view there has been an erosion of medical standards in the care of terminally i l l patients in the Netherlands" (Journal of the American Medical Association ) and "In our view, these data do not support the idea that physicians in the Netherlands are moving down a slippery slope" (New England Journal of Medicine ). 1

2

HISTORY

Euthanasia and physician-assisted suicide have been openly practiced in the Netherlands since 1973, when a doctor received a one-week suspended sentence for ending the life of her severely i l l mother. In 1971, Dr. Geertruida Postma gave her elderly mother a lethal overdose of morphine. Her mother had suffered a brain hemorrhage and was partially paralyzed and deaf. When sitting up, she had to be tied to a chair. She had repeatedly begged her daughter to kill her. Dr. Postma was convicted of mercy-killing, which carries a possible twelve-year prison sentence. Instead, she was given a one-week suspended sentence and a year of probation. 4

128

Suicide and Attempted Suicide • 129 Enough other doctors signed an open letter to the justice minister (comparable to the U.S. Attorney General) stating that they were guilty of the same crime, that the issue could not be ignored. The Dutch Medical Association changed from its previous opposition to assisted suicide, to asking the courts to decide whether physicians had an irreconcilable conflict (force majeure) between their duty to not kill and their duty to relieve suffering by shortening the life of an incurably i l l patient. In 1984, the highest Dutch court made such a ruling. As a result, the justice ministry stopped prosecuting (but continued investigating) both assisted suicide and voluntary euthanasia, as long as the guidelines of the Medical Association were followed. Since then, while there have been a few prosecutions, only one case has resulted in a criminal conviction: nurses who killed (without their consent) several mental patients dying of cancer were sentenced to six months in jail in 1986. The Dutch guidelines for providing euthanasia or physician-assisted suicide were made explicit in 1984. The patient is supposed to be terminally i l l or suffer uncontrollable pain (this has been taken to include emotional pain), and specifically and repeatedly ask for death while rational and free of coercion. There must be no other reasonable way of decreasing the suffering that is acceptable to the patient. Physicians are required to report all such deaths to the medical examiner who, in turn, reports them to the state prosecutor. In 1993 the law was modified to reflect the experience of the prior decade: Doctors are encouraged, whenever possible, to have the patient administer the lethal medication rather than having the physician do it. This decreases the possibility of misunderstandings, ambivalence, or manipulation—and diminishes the burden on the physician's conscience. 3

"This step [assisted suicide] is first a decision of the patient, and eating or drinking the substance is a symbol of the patient's responsibility," said Dr Robert Dillmann, a member of the ethics commission of the Royal Dutch Medical Association. "It is consistent with the decision. An exception should be made when a very sick person is not able to swallow." Many doctors find euthanasia an extremely difficult and burdensome action, and the patient's participation diminishes this burden

130 • Geo Stone slightly. In the past we said that all things being equal, there was no difference between mercy killing and assisted suicide. But in practice, doctors say this is not the same, that there is a difference if a doctor gives a lethal injection or an intravenous drip and, on the other hand, if the patient drinks a potion. 4

Not all doctors agree that the change has been beneficial: "Morally and emotionally it is equally difficult," says family physician Herbert Cohen. "You help prepare the patient and the family and you accompany them. A doctor does not just give a box of pills and walk away." In addition, pills take much longer than injections, typically hours rather than minutes. Dr. Cohen continues, "There are risks because people are terribly sick. A patient can spill the medicine or choke or vomit or fall asleep before the full dose has been taken. It is never simple." b

5

The 1993 changes also emphasized the duty to get a second, independent, medical opinion from an experienced, uninvolved physician. While that rule was already on the books, critics note that doctors often will consult another physician with whom they work or one who knows the patient well. While this has some advantages, it also decreases the likelihood of a fresh perspective, which is the primary point of a second opinion. Although there is widespread agreement in Holland with the current rules—about 80 percent public and physician approval—there is substantial dispute about the boundaries: What to do when people have not explicitly asked for death—for example, in the case of a comatose patient or a severely deformed newborn. The Dutch Medical Association says that it will address this issue soon.

How FREQUENT ARE THESE PRACTICES IN THE NETHERLANDS? After a quarter century of more-or-less open practice, euthanasia and assisted suicide remain uncommon. To summarize the numbers of people involved: There were 128,000 deaths in the Netherlands in 1991. An estimated 25,000 patients began euthanasia discussions with their doctor; 9,000 explicitly requested euthanasia, of which some 2,300 (26 percent of requests; 1.8 percent of all deaths) were consented to and acted upon by the 6

Suicide and Attempted Suicide • 131 physician. In addition, there were about 400 (0.3 percent) PAS (physicianassisted suicides) and 1,000 (0.8 percent) L A W E R (Life-terminating Acts Without Explicit Request), that is, nonvoluntary euthanasia. I do have some concerns with the Dutch process. While there were about 2,700 cases of voluntary euthanasia and PAS (some 4 percent of those who died at home ) carried out each year, government figures show that only about half that number were reported. This is probably because euthanasia is still illegal, and, until 1994 involved police interrogation and the possibility of prosecution; but lack of reporting can also hide abuses. On the other hand, "toleration" does not appear to have set off an avalanche of euthanasia. "Our sense is that [euthanasia] has not increased, but we're not quite sure," said Dillmann. He noted that even with quasi-legalization, there are about three or four requests for euthanasia for each one that was actually carried out. In addition, lives were shortened by less than a week in more than 70 percent of cases. c7

8

9

More troubling, on its face, is the fact that in more than one thousand cases a year doctors had "actively" hastened a death without the patient's request. In about six hundred of these there had been patient discussion of ending life, but no explicit request (as legally required) had been made. It seems impossible to justify making such a decision on the basis of preliminary or tentative discussions, if the patient was competent at the time a lethal injection was administered. On the other hand, if the patient had become, say, comatose, preliminary talks might be the best or only information about his or her wishes on the matter. According to the main author of the Dutch Commission reviewing these practices (the Remmelink Commission), most of these patients were not competent. However, about 20 percent of these cases were not discussed partly (10 percent entirely) because the physician thought it not in the best interest of the patient to do so. These were mostly the patients' longtime GPs: "This is perhaps why they more easily assume that they know what is best for the patient or that they will harm the patient by discussing these subjects." I find this ethically unacceptable. 10

11

12

Of the remaining four hundred cases, in all but two there was no discussion because the patient was no longer mentally capable of making decisions or expressing preferences. Relatives were consulted in 83 percent of these

132 • Geo Stone circumstances. Thus, while there is nonvoluntary euthanasia being carried out, there seems to be little or no involuntary euthanasia. It is plausible that the increased emphasis on physician-assisted suicide, at the expense of euthanasia, will decrease such abuses as exist, but this remains to be seen. To put things in perspective, we should also keep in mind that there were many more cases where life-extending treatment was withdrawn or withheld (about twenty thousand cases) without explicit permission than there were euthanasia/PAS cases. In 87 percent, the patients were not capable of being consulted; in 13 percent they could have been but were not. : 13

In comparison, an estimated 70 percent of deaths in U.S. health-care i n stitutions involve withdrawal or withholding of life-support. This practice, "allowing to die," is considered barbaric by some Dutch physicians, who feel that it prolongs the agony of dying people for no good purpose. Margaret Battin notes that the Dutch are grappling with issues of decision-making for incompetent patients (widely discussed and analyzed in the United States since Quinlan and Cruzan), while the United States struggles with assisted suicide and euthanasia, with which the Netherlands has twenty-five years' experience. However, the significant differences between the two societies would make it a serious mistake for either one to accept the other's experience as a model to blindly follow. 14

15

From my perspective, there certainly is a problem in the Netherlands with what appears to be medical paternalism, but this attitude is widespread throughout the world, and as discussed earlier, is common in the United States as well. As to the question of whether or not this represents the beginning of the "slippery slope," the answer at this time must be: No one knows, if for no other reason than because there is no data on the frequency of these actions prior to the quasi-legalization of assisted suicide and euthanasia. However, after twenty-five years of more-or-less open practice, assisted suicide and euthanasia in the Netherlands are infrequent and abuses rare.

15 EUTHANASIA AND ASSISTED SUICIDE IN THE UNITED STATES

He had been, he said, a most unconscionable time dying; but he hoped that they would excuse it. —Macaulay on Charles II, King of England In November 1994, voters in Oregon narrowly approved an assisted-suicide law, making Oregon the first state in the United States to do so. Similar referenda, with fewer safeguards, were defeated by 54 to 46 percent margins in Washington State in 1991 and California in 1992. However, this is not a new issue. The Ohio legislature defeated a bill to legalize euthanasia in 1906; other proposals failed in Nebraska (1937) and New York (1947). The Oregon law allows doctors to write prescriptions for lethal drugs to be taken voluntarily by a terminally i l l patient. There are four main conditions: 1

1. The patient must have a life expectancy of six months or less. 2. The patient must ask the physician for suicide help on three separate occasions, the last of which must be in writing in the presence of two witnesses, at least one of whom is not family or employed by the hospital or nursing home, and who does not stand to benefit from the estate. 3. There must be at least a fifteen-day delay between the first request, and a two-day delay between the third request and writing the prescription. 134

Suicide and Attempted Suicide • 135 4. There must be second, independent, medical opinion that the patient's judgment is not impaired. No other forms of mercy-killing or euthanasia are permitted. Safeguards of this sort cannot be perfect: If they are too permissive, coercive abuses will occur; i f they are too restrictive, dying people will needlessly suffer while bureaucratic requirements are met. Opponents blocked the referendum in the courts until October 1997, when the U.S. Supreme Court declined to intervene in the case. In the meantime, however, the Oregon legislature, not liking the results of this referendum, voted to hold another one on November 4,1997. The referendum was again approved, and by a much greater margin. Congressional opponents, suddenly claiming federal jurisdiction, got the Drug Enforcement Administration to threaten physicians who wrote such lethal drug prescriptions with loss of drug-prescribing licenses. When this was overturned by the U.S. Attorney General, Janet Reno, they attempted to pass congressional legislation to achieve the same result. The results are not yet in. As of this writing, only a half dozen people are known to have gotten a physician's help to die by means of this law. However, not only its existence, but the intense debate surrounding its court cases and two referenda, has sensitized health-care workers to the needs of dying patients. For example, between 1994, when the first referendum was passed, and 1997, medical use of morphine has increased by 70 percent, Oregon going from eleventh to first in its retail distribution of this pain medication. Similarly, deaths in hospitals have decreased dramatically; now 60 percent of people are dying at home or in nursing homes. Hospice use has increased from 21 percent of deaths in 1994 to about 32 percent in 1997, and all of Oregon's fifty-seven hospices now accept patients who say they intend to avail themselves of this new law. 2

Nevertheless, the debate is certainly not over. Let's look at some of the arguments in more detail.

136 • G e o S t o n e

ARGUMENTS SUPPORTING THE "SLIPPERY SLOPE" THESIS a

Most opponents of assisted suicide cite the "slippery slope" argument: Crudely stated, assisted suicide (initially, death in a few sympathetic medical situations for those who have asked for it or on the basis of mercy) makes euthanasia (including death for people who have not expressed such a request) more acceptable, which, sooner or later, leads to the legal killing of people who are considered in some way "defective" or "inferior." In the words of Bishop Joseph Sullivan, 15

If voluntary euthanasia were legalized, there is good reason to believe that at a later date another bill for compulsory euthanasia would be legalized. Once the respect for human life is so low that an innocent person may be killed directly, even at his own request, compulsory euthanasia will necessarily be very near. This could lead easily to killing all incurable charity patients, the aged who are a public care, wounded soldiers, all deformed children, the mentally afflicted, and so on. Before long the danger would be at the door of every citizen. 3

I think this concern is quite legitimate. I would briefly put forth three arguments supporting and three opposing it. First, I have no reason to believe that a medical and legal system that is capable of the ethical blindness of torturing dying people by keeping them alive in medically hopeless situations contrary to their desire, is not also capable of erring in the other direction. The shameful Tuskeegee syphilis study, the formerly common use of prisoners as medical test subjects, the involuntary sterilization programs associated with the eugenics movement, and a variety of radiation experiments on unwitting subjects show us that American medicine and law can fail and, at times, have failed to protect the people who need protection most. 4

Two brief examples may be useful: (1) In one study, 525 men with strep throat were not treated with penicillin, though the experimenter knew that such treatment would prevent rheumatic fever (with probable severe heart damage). As a result "twenty-five men were crippled, perhaps for life." The

subjects were not informed that any experiment was being carried out. (2) Cancer cells were transplanted into a patient's mother, who was told by the experimenter that the purpose was "the hope of gaining a little better understanding of cancer immunity and in the hope that the production of tumor antibodies might be helpful in the treatment of the cancer patient." The daughter died the next day, the mother a little over a year later—from the metastasized transplanted cancer. 6

Physicians, like other people, respond to financial, legal, and social incentives. I would note that in Nazi Germany, half of the medical doctors in the country were members of the Nazi Party and 7 percent joined the SS, a much higher proportion than that of any other academic profession. A n d , "the abundant availability of human guinea pigs among people labeled as inferior or subhuman was exploited by doctors as a unique opportunity for scientific research." Second, the concept of a slippery slope is plausible: Fewer people will go two steps past acceptable behavior than will go one step. If we move the definition of "acceptable" by a step, we have also turned two steps away into one step away Moving the norms also moves the boundaries. For example, in 1993 Boudewijn Chabot, a Dutch psychiatrist, was tried on charges of helping a depressed (but physically healthy) patient commit suicide. He was acquitted when the court ruled that intense mental distress might also justify assisted suicide. Thus we have moved from "terminal illness" to "intractable pain" to "intense mental distress." Third, we are already partway down the slope. Most Americans morally accept killing in self-defense, just war, capital punishment, or abortion. Current American medical practice (if not theory) includes violations of patient autonomy, both in the direction of maintaining life and of ending it. Patients or their surrogates are sometimes pressured to agree to do not resuscitate (no-code) orders. There are reports of no-codes being written into a patient's chart in pencil, to allow erasure. Advance directives are widely ignored. 7

ARGUMENTS AGAINST THE "SLIPPERY SLOPE" THESIS Counterarguments to the slippery slope thesis might be, first, that numerous societies have practiced infanticide, assisted suicide, or euthanasia without extending the limits of acceptable practices later. In one study 50 percent of the societies reviewed used some form of hastening death in the elderly For example, an Eskimo tribe might, during starvation times, abandon some elderly members, asphyxiate them, or encourage them to go outside to die—but murder (though not warfare) was almost unheard of. In nineteenth-century Europe, unwanted babies were given to foundling homes, which often had such high death rates that the people who ran them were called "angel makers." Female infanticide is common in India and China. None of these societies proceeded to build concentration camps or otherwise systematize murder, as slippery slope proponents claim will inevitably happen. A n d , despite appalling American examples of abuses of patients in medical experiments, they have become less, not more, frequent. There are few calls to end all human experimentation. Rather, the demands are for an end to the abuses, and this is as it should be. As the Presidential Commission for the Study of Ethical Problems in Medicine reported, 11

12

13

... much more is needed than merely pointing out that allowing one kind of action (itself justified) could conceivably increase the tendency to allow another action (unjustified). Rather; it must be shown that pressure to allow the unjustified action will become so strong once the initial step is taken that the further steps are likely to occur ... [and] such evidence is quite commonly limited. 14

Second, the Nazis (commonly cited by slippery slope proponents) did not start with voluntary euthanasia from a sense of compassion and slide down the slippery slope to involuntary euthanasia and sterilization, and then to mass murder—all within ten years, mind you. Their rationale had less to do with relieving suffering than with achieving racial purity and medical knowledge. 15

Suicide and Attempted Suicide • 139 The slippery slope argument is also weakened to the extent that one can get down the slope while omitting the "first" step. If Stalin's or Pol Pot's concentration camps existed without the prior approval of the practice of assisted suicide and euthanasia, it makes the association, let alone claims of cause and effect, unconvincing. In any case, the Nazi death camps were certainly not caused by the earlier program of euthanasia; nor does it seem likely that the Nazis would have refrained from mass murder and genocide had they not first implemented their program of voluntary euthanasia for Aryans. One might make the parallel argument that the Nazi example of sterilization abuses should cause us to forbid voluntary sterilizations lest we slide down this same slope. Involuntary sterilization, including that of children, also took place in this country, before, during, and after the Nazi era; yet such abuses have decreased, rather than becoming the norm, while voluntary sterilization has become more widespread. The concept of a slippery slope also becomes less persuasive when we realize that it can be—and has been—applied, both honestly and dishonestly, to just about any issue that people care about. Nothing has only one effect, and abuse can follow from any good. Indeed, one could reasonably argue that the tortures sometimes inflicted through prolonged dying are predictable slippery slope abuses arising from advances in medical technology. Are we prepared to give up the benefits of this technology in order to preclude such abuses? 0

It is certainly true that i f you prohibit all assisted suicide, you will avoid disputes about where to draw the line. But simplicity has a price too, and ignores the hard cases. For example, "[A Dutch] doctor, Henk Prins, will go on trial for ending the life of an infant born in 1992 with severe spina bifida. Though the baby's parents wanted the death, and the infant was in pain, Prins is being charged with premeditated murder in a new test of the limits of the euthanasia guidelines." As Ronald Dworkin notes, "No set of regulations can be perfect. But it would be perverse to force competent people to die in great pain or in a drugged stupor for that reason." Other objections to assisted suicide center on the pressure a dying—or 17

18

19

140 • Geo Stone merely old and ill—person might feel to make a decision to die. In the American health-care system, that motivation could well be financial. Some sources of this pressure might be: Family: Herbert Hendin cites a Dutch study to the effect that patients in that country are subject to such family coercion. However, the existence of living wills (valid in every state and affirmed by the Supreme Court), which limit medical care, already make people subject to this kind of incentive. 20

In any case, it's not clear that this is a significant problem in the United States: "Talking with hundreds of terminally i l l over the past few years, I've yet to hear this complaint voiced," notes Stephen Jamison. What he has found, instead, "is an often not-so-subtle coercion by the dying themselves to ensure the participation of others in their deaths." One should also be aware of the possibility of coercion to stay alive, contrary to the patient's wishes. An institution (for example, hospital, insurance company, H M O , or government agency) concerned about covering its bottom line. Health-care expenditures are 14 percent of the U.S. gross domestic product ( G D P ) and the highest per-capita in the world. An estimated 30 percent of health-care costs occur in the last six months of life. The proportion of old people is increasing and will numerically peak with a surfeit of geriatric baby-boomers early in the twenty-first century who will be a financial burden to the outnumbered generation Xers. A d d these together and you're looking at enormous pressure to keep costs down. The terminally ill and the elderly will likely bear the brunt of any resulting health-care rationing or coercion to die. In fact, there already is such coercion: Medicaid requires that a person facing a long stay in a nursing home first use up almost all of her assets before becoming eligible for public assistance. While this seems reasonable from one perspective, the quite predictable result is that a person, especially one who is terminally i l l , must choose between exhausting these funds for a relatively short extension of life or dying earlier and leaving money for spouse or children. 21

22

One suggestion is intriguing. Besides the usual explicit request by the patient and two-independent-physician approval, the patient would be asked, "Is the care you are now receiving adequate?" If the patient or patient's-advocate said no, this situation would have to be rectified before as-

Suicide and Attempted Suicide • 141 sistance to die could be provided—if it was still wanted. It's possible that such a system might even improve health care for the people who need it most, if it were applied honestly. In addition, it would be naive to believe that the terminally i l l do not face these same issues in the absence of assisted suicide. For example, one study of cancer and A I D S patients found that three-quarters of them wanted to limit medical expenditures: 23 percent would be willing to spend all their resources, while 27 percent would not wish to spend any of it; the average amount to be spent was 43 percent of their life's savings. Unmarried patients were willing to spend 19 percent more than married ones. When asked about being dependent on family and friends for care, 14 percent said they would want to live as long as possible; but 28 percent said that they would not want to live even one day in that situation! This study does not address whether terminally i l l people would feel more or less pressure to shorten their lives in order to limit being a burden on family and friends if assisted suicide/euthanasia were legalized. But it does show that they already make these calculations. 23

The fact that assisted suicide is illegal, combined with its increasingly common practice, leaves us with the worst of both worlds: It is carried out underground, without supervision or review; sometimes by physicians, but often by people who have limited knowledge of how to go about it. As Lonny Shavelson says, "The present prohibition against legal assistance in suicide has guaranteed that not a single [American] physician has ever assisted in the death of a patient while following set rules, nor under the observation of her peers, nor under the watchful eyes of the law." In addition, since active euthanasia is more obvious and conspicuous than withdrawing or withholding treatment (both commonly done in the United States and throughout the world), it is less subject to abuse. Making these practices open and legal would compel us to erect protections against abuses, which would, I believe, also lead to better protection and clarity in cases of withdrawing or withholding treatment. 24

25

Reasonable people can disagree. For my part, I come out, reservations and all, squarely on the side of assisted suicide. It's not a panacea. People will still kill themselves on account of present misery; but not over fears of future helplessness. Improved medical care—and caring—for the dying would de-

142 • G e o S t o n e

crease the impetus for suicide, assisted or not. But in the absence of such care, or when it fails, each of us who so decides should have the option of a chosen death. In the case of terminal illness, there are still choices to be made. A return to health is not one of them. What remains are the choices of how and when to die: What image and memories of yourself to leave behind, what resources to use, and what to pass on to your heirs and society. Some questions that a dying person who is considering suicide might want to think about: 26

• Is suicide morally appropriate for me, given my circumstances, values, religious beliefs, suffering, and responsibilities? • Can I kill myself without assistance? If so, is involving someone else appropriate? • W h o will be harmed by my suicide? How can I minimize this harm? • Is suicide a rational choice for me? W h y do I think so, and what are the counterarguments? Is suicide an attempt to assert some control over an illness that has taken most choices from me? Is it motivated by present suffering or fears of future consequences of my illness? The methods to achieve these choices include (1) leaving things to chance, as most people do, and trusting "the system" to make the decisions; (2) making advance directives in the hope, frequently unjustified, that they will be followed; (3) committing suicide while still able to do so, sacrificing some time in exchange for control of life's endgame. Each option has advantages, disadvantages, and risks, and the third option disappears if you are incapacitated. The most flexible individual strategy would seems to be: 1. Find a physician who is open-minded about these issues and willing to talk with you about them; 2. Have a living will and a power-of-attorney document, and a healthcare proxy who understands, agrees with, and will carry out what you want;

Suicide and Attempted Suicide • 143 3. Utilize home-hospice or comfort care; 4. Have a means of killing yourself available if points 2 and 3 fail and you're still able to carry it out; 5. Have someone willing to help you in an assisted suicide, or willing to kill you (if that's what you want) should you become unexpectedly incapacitated during this process and advance directives are being flouted. Be aware that the last two eventualities may well have legal repercussions for your assistant. It would be far better if suicide were never the best choice or if doctors could be counted on to sensitively guide end-of-life decisions in the interests of the patient, as defined by the patient. Physicians often have a preexisting relationship with a patient that allows an accurate assessment of the latter's prognosis and emotional state. A n d physicians are in the best position to apply effective and humane methods of assisted suicide or euthanasia. But the law forbids them to offer such help under any circumstances. Until that changes, patients will continue to kill themselves in desperation, assisted suicide and euthanasia will continue to resemble back-alley abortion, and books like this one will continue to be necessary.

PART II SUICIDE METHODS

16 How DANGEROUS ARE VARIOUS METHODS OF SUICIDE?

You got to be careful if you don't know where you're going, because you might not get there. —Yogi Berra If you torture numbers long enough, they will confess to anything. —Charlie Thayer This chapter looks briefly at two questions: (1) How dangerous are various suicide methods? and (2) can suicide methods be used to predict the likelihood of later suicide among survivors? There is a huge amount of material on suicide, but surprisingly little information comparing the fatality rates of different suicide-attempt methods. There appear to be only two large studies, one published in 1961 by Edwin Shneidman and Norman Farberow, the other in 1974 by Jaime Card. Their data are generally similar, which gives us some confidence in them. Later chapters will look at individual methods of suicide in much more detail, but this is where you can compare them side by side. Guns are the most lethal method. Of every ten attempts, eight or nine are fatal. Hanging, drowning, and carbon-monoxide poisoning are almost as deadly; other gases, poisons, and drugs tend to be less so. Attempting suicide by cutting or stabbing are the least dangerous: only one of twenty at147

148 • Geo Stone tempts is fatal. Recent data suggest a fatality rate of 1 to 2 percent in deliberate drug overdoses. Keep in mind that all of these numbers show probabilities; there are no certainties. Every method may be lethal, and every method has been survived. You should also be cautious because the categories are broad and include differing techniques and intents—cutting one's wrist is not the same as cutting one's throat. 1

Look at the numbers. Table 16.1 shows how lethal various suicide methods are by percentage and by rank. Number one position is held by gunshot, fatal in 85 percent of cases.

The category showing the greatest difference in lethality between the earlier and the more recent data is drugs/poisons. The decreased fatality percentage is due mostly to the widespread replacement of barbiturates with safer sedatives. Secondary reasons include use of less toxic antidepressants and, perhaps, better hospital treatment. While not reflected yet in these numbers, carbon-monoxide poisoning by car exhaust is much less likely to be fatal (and will take much longer) because recent low-pollution cars emit far less carbon monoxide than do older cars. Jumping, in Hawaii, may be singularly dangerous because of the easy availability of cliffs, ocean, and volcanoes, but this is speculation.

J. J. Card studied 2,729 suicides and suicide attempts from Pennsylvania.

Since raw numbers like these can be confusing, we can try combining them in a variety of ways in order to find patterns. For example, in the next table (Table 16.4), we look at how dangerous the sundry methods were, calculated by two different methods. The first, seriousness of result (column 2) is an average (weighted mean) of the outcomes for each method; the more severe the consequences, the higher the number. This table uses the same 1through-6 scale as Table 16.3. Gunshot has the highest mean seriousness (5.84); cuts are the lowest (2.81). Is the fatality rate of a given method a good predictor of the seriousness of survivors' injuries? Not necessarily: Jumping, hanging, and carbon-monoxide poisoning, for example, are more lethal methods than are drugs and poison. Yet the latter two cause more serious injury, as shown in column 3 (seriousness of result in survivors), on a 1 to 5 scale, when number 6, death, is excluded. Does this tell us that jumping survivors have less severe injuries than do drug overdose survivors? Again, not necessarily; glancing back to the possible outcomes in Table 16.3, we find that there's no information concerning how many of these injuries are permanent or disabling. A l l we can tell is that a smaller proportion of jumping than drug-overdose survivors were hospitalized or put into the I C U . However, as you will see in later chapters, while drug overdoses may be acutely dangerous and require I C U intervention, jumps are more likely to leave you crippled.

How LETHAL DO PEOPLE BELIEVE VARIOUS SUICIDE METHODS TO BE? Like carpenters they want to know which tools. They never ask why build. — A n n e Sexton from Wanting to Die In the introduction, I said that many people don't have an accurate idea of how dangerous particular suicide methods are. As a result, they may kill themselves when they intend to survive, and vice versa. This lack of knowledge increases the possibility of permanent injury In one study, 291 nonexperts and 10 pathologists were asked to estimate the lethality of a number of suicide methods. (The nonexperts, all college students, are probably not typical of suicidal individuals of various ages and backgrounds—but they're easier to recruit.) The college students: 4

Suicide and Attempted Suicide • 153 1. Drastically overestimated the lethality of drug overdose and slashed wrists. For prescription-drug O D , the student estimate was 61 (on a 100 point scale) while the pathologists' estimate was 12; with limb cuts, the respective numbers were 44 and 6. 2. Underestimated danger from gunshot wounds and a cut throat. The student estimate for a shotgun wound to the chest was 77; pathologists said 96. 3. Had a much larger standard deviation (not shown) for their estimates than did the pathologists. 3

There were often large differences between the student and pathologist estimates for time and pain. However, it may be that the wrong group of experts was surveyed: Big-city emergency-room physicians would have been a better choice since they have considerably greater experience with living suicide attempters than do pathologists. The implications of this study are important—and scary: • The medical literature generally considers most overdoses and limb cuts to be "ambiguous," "less serious," or "cries for help" methods, because the fatality rates are low. As a result, survivors may not be taken seriously. However, to the extent that attempters believe that these are seriously lethal means—as the student estimators do—using them becomes less a cry for help than an attempt to die. A n d not being taken seriously may convince someone to try again, using a more lethal method. • Some people will die because they fatally underestimate the risk of their method; others will survive due to overestimating the danger. Even when the nonexpert's average estimate is reasonably accurate, the large standard deviations mean that many of the individual estimates are far off.

THE CONSEQUENCES OF INTENT

You might suppose that people who make a lethally intended suicide attempt would be at greater risk of later suicide than those whose suicide at-

154 • Geo Stone

tempt was a call for help or attention. However, this seems not to be the case. As mentioned earlier, surviving a serious suicide attempt may be therapeutic or cathartic, for a variety of reasons: getting help or punishing oneself, for example. Or it might be so traumatic as to effectively discourage a repeat attempt. Table 16.5 shows the percentage of suicide-attempt survivors (by each method) who did and who did not subsequently die from suicide. These methods are ranked by risk of subsequent suicide (risk rank) and compared to the lethality of the survived method (fatality rank). What does it mean? If there were a "strong positive correlation," it would show that survivors of highly lethal methods tended to later kill themselves significantly more often than survivors of low lethality methods. A "strong negative correlation" would show they did so significantly less often. "No correlation" would show a lack of statistical relationship between the two events. What we find is a very low positive correlation (+0.264), which is not "statistically significant"; that is, there is essentially no relationship. Some high-lethality methods have many subsequent suicides, some have few; and likewise for low-lethality methods. The least lethal method (cuts) is eighth in predicting future suicide; the most lethal (guns) is sixth. The best predictor of future suicide (plastic bag suicide attempt) was fifth in lethality; the worst (fire) was seventh. From this data we see that we can't predict the likelihood of later suicide based on the method that was survived. 5

The fatality rank differs slightly from Table 16.1, in which the data from t w o studies are combined. Source: Card, 1974.

What if we looked, instead, at the likelihood of future suicide in relation to the medical seriousness of the earlier suicide attempt? This is shown in Table 16.6. Of the most seriously injured only 2.67 percent later killed themselves, while 10.84 percent of those who had no- or self-treatment later committed suicide. However, while the correlation is negative (-0.500), it does not reach statistical significance. Still, it's reasonable to wonder if the "more serious" attempt forced family/friends to deal with problems in a way or to a degree that "less serious" attempts didn't; or, perhaps, if being close to death increased the attempters appreciation for living. 6

The overall suicide rate among those who have survived a suicide attempt is generally found to be about 1 to 2 percent the first year, and decreases thereafter, with a lifetime risk of 5 to 15 percent. 7

156 • Geo Stone Some more recent data are consistent with Card's ideas, some are not. In one study of sixty cases of survived suicide attempts, there was no correlation between the seriousness of the intent and the lethality of the attempt. Similarly, of 156 consecutive trauma admissions using frequently lethal methods (that is, excluding drug overdoses and wrist cuts), 24 percent died. These were serious attempts, but there were few—only seven— subsequent attempts among the survivors, none fatal in the 2.8-year average follow-up, and they tended to use less lethal methods (three by drug overdose, three by wrist cut). Similarly, ten-year follow-up on ninety-four people who survived the usually lethal procedure of jumping in front of a train found no higher suicide rates than those who had survived less lethal methods. 8

However, other data show a different picture. A five-year follow-up of 886 suicide-attempters found that 6.45 percent of those whose try was classified as "serious" killed themselves, compared with 3.1 percent of the "non- or less-serious" attempters. Similarly, in a group of 1,018 people treated for drug/poison suicide attempts, of those who had intended to die 21 percent later killed themselves, almost three times the rate of those whose lethal i n tentions were assessed as "mild." 11

12

From a number of reports, survivors of suicidal drug overdoses often don't fare particularly well. In one Norwegian study, 227 of 1,487 survivors had died over an average of four-and-a-half-year follow-up, compared to an expected thirty-two deaths (based on standard mortality tables). Thirtynine percent of the deaths were classified "suicide," 44 percent "natural," 9 percent "accidental," and 8 percent "other" (for example, homicide). Each of these categories had more deaths than expected. The suicide death rate was 1.3 percent per year, about sixty times the overall national suicide rate. Thus, the question of whether a serious suicide attempt is more predictive of subsequent suicide than a less serious attempt—like many other issues concerning suicide—remains unresolved. 13

17 ASPHYXIA

Asphyxia is any process that cuts off the oxygen supply to the brain. This includes such seemingly unrelated methods as a plastic bag over the head, suspension hanging, and carbon-monoxide poisoning. A l l forms of asphyxia are potentially lethal, but they differ widely in how painful they are. Death usually occurs between five to ten minutes after complete asphyxia. Some of these methods are suitable for suicide; none are appropriate for a suicidal gesture. High FATALITY RATE: High; around 80 percent PERMANENT INJURIES: Moderately likely LETHAL INTENT:

PROS AND CONS OF SUICIDAL ASPHYXIA

Pros: • Can be quick and painless, if done knowledgeably • Does not require much strength or equipment • Some methods can be carried out by a person unable to get out of bed Cons: • Possibility of brain damage if asphyxia is interrupted • Some methods leave a gruesome cadaver

WHAT IS ASPHYXIA?

In the most general sense asphyxia is any condition that causes the heart to stop beating by interfering with the body's capacity to inhale or utilize oxy157

gen. Oxygen is ultimately necessary for all human metabolic activity, and its absence is rapidly fatal. Since the brain is the organ most sensitive to lack of oxygen, as a practical matter asphyxia is anything that cuts the brain's supply of, or ability to use, oxygen. Obviously the rest of the body needs oxygen, too, but the brain responds most quickly and catastrophically to its absence. Looking at the various causes of asphyxia outlined below, one can begin to appreciate that methods as seemingly dissimilar as carbon-monoxide poisoning, strangling, and drowning are all fundamentally alike in how they kill. I. Mechanical interference with oxygen uptake A. Compression of neck or chest 1. Ligature a. hanging b. strangling 2. Nonligature a. compression of chest B. Obstruction of airway 1. External a. smothering 2. Internal a. inhaling foreign object b. swelling (e.g., from allergic reaction or blow) C. Depletion of oxygen (e.g., plastic bag, drowning, vacuum) II. Chemical interference with oxygen uptake or utilization A. Replacement of oxygen by nontoxic gas (e.g., helium, methane, nitrogen) B. Depletion of oxygen 1. Fire 2. Other oxidation (e.g., rusty S C U B A tank) C. Interference with utilization of oxygen at cellular level 1. Carbon monoxide 2. Cyanide Some of these topics are treated separately or in more detail in other chapters (hanging, drowning, carbon monoxide, cyanide); others are too rarely

Hanging and automotive carbon monoxide accounted for the large majority of these suicides. Drowning is a distant third, though its actual numbers may well be a good deal higher than reported, since it's easier to disguise suicidal intent with drowning than with either hanging or carbonmonoxide poisoning. Plastic-bag asphyxia is unusual in that there are as many women as men who use this method.

How AND WHY IS ASPHYXIA DANGEROUS?

Death is a process, rather than an event. Different cells and tissues die at different rates; for example, the brain will not normally survive more than a few minutes without oxygenated blood circulation, while connective tissue and muscle cells may remain alive for many hours. This is one reason for the current medical ability to reattach severed limbs, but not heads. 2

At a basic level, all asphyxial injury is due to cutting off the brain's oxygen supply This can happen directly, by interference with breathing (for example, from pressure on the chest or on the front of the neck) or by removal of the oxygen from the air. The same results occur indirectly if blood can't pick up oxygen (for example, in carbon-monoxide poisoning), or if oxygenated blood is prevented from reaching the brain (for example, by pressure on the large arteries in the neck). Irrespective of the method, complete asphyxia causes quick—typically within two to three minutes—unconsciousness, followed by brain damage, ending in death. Since the degree of oxygen depletion varies with the method, so does the length of time needed for any given result. Resuscitation may produce a survivor with brain damage, which is often long-lasting and sometimes permanent. Four to five minutes of circulatory arrest causes brain damage in around half of patients and approximately five to ten minutes of complete oxygen cutoff is generally fatal (unless body temperature is abnormally low, as in drowning in icy water), though the heart will continue to beat for several more minutes. 4

3

Let's look at some of the methods in more detail. STRANGULATION

Strangulation causes asphyxia by means of pressure on the neck from a ligature or from someone's hands. The weight of the victim's body plays no part, which is what distinguishes strangulation from hanging. Since manual selfstrangulation is unknown and probably impossible (your hands relax when you become unconscious), all cases of manual strangulation are considered homicides. I suppose this also makes manual self-strangulation the perfectly safe suicidal gesture, but, by the same token, it would not likely be taken seriously.

Suicide and Attempted Suicide • 161 Pressure on the neck can close the airway (trachea, or windpipe) at the front of the neck or compress the common carotid (right side) and vertebral (back of neck) arteries or jugular vein (left side), or some combination of the above. The jugular vein is easiest to compress, followed by carotid and vertebral arteries, followed by the trachea. (See Hanging chapter for details.) M u c h more pressure is needed to close the airway than to close the blood vessels in the neck, and is unnecessarily painful. It is entirely feasible to protect the airway with stiff padding, and still kill oneself by tightening a ligature around the neck, thus shutting off blood flow to or from the brain. b

Because they operate at higher pressure, the carotid arteries (which regulate blood flow into the head) require more external pressure to compress than does the jugular vein (which takes the blood out). A tight, quickly applied ligature would squeeze both shut, leaving a body with a dusky, bluetinged (from deoxygenated hemoglobin in the blood) face. Lesser pressure, compressing the jugular but not the carotid, would allow blood into, but not out of, the head. This would result in a swollen, bluepurple head, often leaking blood. If aesthetics are an issue, protecting the left side of the neck decreases compression of the jugular, allowing blood to leave the head, and thus minimizes engorgement of the head with blood. Suicidal strangulation is uncommon, but certainly not unknown. It is generally done by one of three means: (1) knotting a rope or piece of cloth around the neck in such a fashion that it will not come undone when consciousness is lost; (2) twisting a stick or rod under the ligature so that it tightens, and then stays caught under the jaw or chin after unconsciousness; (3) wrapping multiple turns of cord around the neck without any knot at all, depending on friction to hold it in place. Pressure on the windpipe is painful, but even lethal pressure elsewhere on the neck may produce little or no distress; thus, if the front (and, less critically, the left side) of the neck is well padded, none of the following techniques ought to be particularly painful. But all are potentially deadly. Method one is straightforward: a ligature is wrapped once or twice around the neck and quickly knotted. This often looks similar to a homicidal strangulation, but can usually be distinguished from it by the absence of scratches on the neck (produced either by the attacker or the victim) and of internal neck injuries.

162 • G e o S t o n e

A more-or-less typical case of a suicidal strangulation is described in a forensic medicine text: A woman aged seventy-three was lying full length on the floor of a bedroom, which she shared with another patient in a nursing home.The bed clothing had been thrown back in a manner consistent with getting out of bed.There were no signs of any struggle. She was dressed in a nightgown and a brown stocking was round her neck; the fellow of a pair was seen suspended over the head of the bed. The stocking was applied with a half-knot at the nape on the first turn and with another half-knot at the front of the neck.The first turn was tight, but the second, although close to the first, was easily released.There were no other signs of violence, but a little bleeding, which produced a small stain, I inch in its diameter; had occurred from the nose; the stain was directly below her nose. Her face and neck, above the ligature, were congested and of purple colour Bleeding had occurred beneath the conjunctivae [eyelids], but petechial hemorrhages [pinpoint hemorrhages often found in asphyxia] were not seen in the skin of the forehead and face. The tongue protruded, but was not bitten; she had dentures, but these were on her bedside table. The author goes on to describe the generally mild injuries in detail and concludes, "The cause of death was asphyxia, following the application of a relatively broad, soft ligature to the neck with sufficient force to obstruct the veins and, to a lesser degree, the arteries of the neck; there was also obstruction of the air passages. The mode of application of the ligature was consistent with self-strangulation, as was all the other evidence." Sometimes it's difficult to determine whether death resulted from suicidal or from homicidal strangulation. For example, a soft ligature applied with skill and removed soon after death will create problems at autopsy. In one case a woman strangled her child with her husband's necktie. She tied no knot and held the ends of the necktie instead, until the deed was done and then removed it. As a result, there was no externally visible neck injury. But she was caught anyway. 4

Suicide and Attempted Suicide • 163 It isn't unusual for defense counsel in a case of homicidal strangulation to try to muddy the waters. In one instance, the body of a forty-two-year-old woman was found in a grave in her well-screened back yard. Clothesline was wrapped twice around her neck and tightened with a half-knot. A man was arrested. At trial, the defense described the ligature as more like a "lover's" knot than a murderer's, but had a hard time explaining the presence of a large piece of cloth forced down the victim's throat and several additional i n juries. Faced with this evidence, counsel admitted that the injuries were the cause of death, but suggested that they were the results of a violent quarrel. The accused's failure to report the death was attributed to his preference for conducting his own funeral arrangements. His contention, that he wanted to give her a "Christian burial," was described by the prosecutor as one of the worst pieces of hypocrisy he had ever heard. The jury was equally unimpressed by his solicitude and convicted him of murder. 6

Method two is rather like applying a tourniquet. There is generally a single loop which is attached loosely and usually knotted with a granny or reef knot. A rod (still called a "Spanish windlass" in honor of its former use in that country for judicial executions) is placed under the ligature and twisted to tighten. Tightening needs to be accomplished fairly quickly in order to get a few extra twists in before unconsciousness intervenes. This is done because the twist may partly unwind when no longer held in place—but only partly. Usually the rod hangs up on the side of the jaw and enough compression is maintained to cause death. Occasionally, quite unwieldy rods are used to tighten the ligature, as in a case where a man used a fireplace poker. Items this large will certainly prevent the ligature from untwisting, but are hard to tighten rapidly. Method three, multiple loops, is the least common since, if the ligature is tight, there isn't time to do very many loops; if it is loose, it's ineffective. In one case, however, a fifty-three-year-old man succeeded despite these difficulties. He wrapped twine around his neck thirty-five times, tied a knot, and tightened it. He then bent forward on his knees with his head down, which increased his neck circumference, and thus, pressure from the twine; this is the posture in which he was found. Since this is an unusual position, the police were initially suspicious. However, there was no internal damage to the fairly delicate anatomical structures in the neck, a fact consistent with suicide, but not murder.

CHOKING

Choking is the blockage of the internal airway by some foreign object. (Choke and sleeper holds, sometimes used by police and muggers, are discussed in the chapter on hanging.) Some examples are: 1. Inhaling vomit while unconscious, typically after drug/alcohol overdose. While this may be the actual cause of death, it is unpredictable and rarely, if ever, the intended method. 2. Aspiration of food. This is a common (and public) enough accidental cause of death that it's been nicknamed the "cafe coronary." The food item is often a chunk of meat, and the victim often is drunk. Sometimes there is no sign of respiratory distress—the victim just sits back on the chair, or falls over, dead. These are cases of cardiac arrest triggered by food stuck in the airway. Choking on food is also occasionally seen among some mental patients who try to "wolf" (a canard—wolves don't eat in this way) down their own and/or other inmates' food. 3. Young children are indiscriminate about what they put into their mouths, and readily insert things that will block breathing i f inhaled. The emergency treatment for life-threatening choking is the Heimlich maneuver widely taught in first-aid courses. It consists of holding the victim from behind and putting sudden pressure on the diaphragm by a quick squeeze with your locked hands. An emergency self-Heimlich can be done (if you don't panic) by quickly shoving your diaphragm (just below where your ribs come together between your chest and belly) hard against the rounded corner of a table, banister, or other sturdy object. Falling onto a round object such as a soccer ball or your fists should be similarly effective. In any case, the idea is to dislodge the blockage by a sudden increase in exhalatory air pressure. If this isn't done, or fails, the desperate victim tries harder to inhale, which only wedges the object more firmly. Blood pressure and carbon-dioxide levels rise; lack of oxygenated (red) and excess of unoxygenated (blue) hemoglobin causes the victim to turn bluish; convulsions due to insufficient oxygen and too much carbon dioxide often occur; heartbeat races, falters, then stops.

Suicide and Attempted Suicide • 165 COMPRESSION OF CHEST

If the chest and diaphragm are compressed, the ability to inhale is i m paired. Since this can be done with few, if any, external signs of injury, it was once a notorious method of disguising murder. It was popularized by two Ulstermen, William Burke and William Hare, who killed a number of derelicts in Scotland by this means. The motive was money: They committed these murders in order to sell the bodies for dissection at the local medical school. c

Hare was keeper of the Log's Lodging House in Edinburgh. He and Burke sold their first corpse, a male who had died a natural death at the lodging house on November 29, 1827, to a Dr. Robert Knox for seven pounds, ten shillings, for dissection at Knox's anatomy school. Deciding that there was a career opportunity here, over the next eleven months they enticed at least fifteen people (one at a time) to the lodging house, got them drunk, and smothered them. One would hold the victim's legs while the other would sit on his or her chest. Hare testified that, in one murder, Burke, "got stridelegs on the top of the woman on the floor, and she cried out a little, and he kept in her breath. . . . He pressed down her head with his breast.... He put one hand under the nose and the other under her chin, under her mouth." 10

The technique was given the name "burking" in their honor. After they were caught, Hare turned King's evidence, was eventually released, and disappeared with Burke's former mistress, by then Hare's wife. He supposedly died a pauper in London in 1859. Burke was hanged in 1829; the doctor was never charged. Other than accidents such as car wrecks, construction cave-ins, falling beverage vending machines (surprisingly common, and usually due to people trying to rob the machine, or to irate customers trying to get their money back ), and stampeding mobs (most frequently soccer or music fans), the main incidence of fatal chest compression is in the course of police arrests. If a prisoner is facedown on the ground or in the back of a police car, with hands forced behind in cuffs and the weight of the policeman on his back, there may be lethal results. This is especially, but not only, true if the prisoner is struggling violently or has taken alcohol or other depressant drugs. d

6

Compression is also the method used by constrictor snakes to kill their

166 • Geo Stone prey: They wrap themselves around their victim, a bit more closely each time it exhales. Inhalations become progressively more difficult until the victim dies of asphyxia. It is not crushed in the sense of having broken bones, except incidentally. There are four recorded cases of deaths due to constrictor snakes in the United States. Three were due to large pet snakes: Two killed infant children of the owners; one adult was killed while sleeping on the floor. The fourth death was that of a zookeeper. None were considered suicides; nor is it a recommended method of suicide. 11

SMOTHERING

"Smothering" is the blockage of the nose and mouth. This is sometimes seen in homicide since it simultaneously minimizes the injuries that generate suspicion of foul play and noise (screams, gunshots, etc.) that might attract unwanted attention. However, unless there is a major mismatch in strength, the chances of killing someone quickly and without producing visible injury are slim. In the eighteenth and nineteenth centuries the accidental smothering of infants was common in England. This was called "overlaying" and was attributed to widespread drunkenness among the lower classes, supposedly due to the availability of cheap gin. Since young children generally shared their parents' bed, if the parents were drunk, they might innocently (or otherwise) lie on and asphyxiate a small child. Nowadays, in the United States, infants are usually kept in their own cribs, and their occasional mysterious deaths are attributed to Sudden Infant Death Syndrome or SIDS. f

8

Sometimes people are gagged in the course of other crimes. If the gag slips upward to also block the nose, or is inhaled, death from asphyxia can result. Suicidal smothering is rare, requiring extraordinary will power, but is occasionally seen among prisoners and mental patients. One prisoner killed himself by stuffing pieces of cloth into his mouth and nose, and holding them in place with a handkerchief. Another was found dead in a mental hospital with a pebble lodged in each nostril and mouth stuffed with cloth. : It's also possible to smother oneself by lying facedown on soft bedding or clothing. This is occasionally the cause of death for people who are drunk or incapacitated for other reasons, but I'm not aware of cases in which a physically and mentally unimpaired adult has committed suicide by this means. 12

13

Suicide and Attempted Suicide • 167 Accidental smothering occurs mostly in small children. Some of these cases are due to an infant being unable to turn over from its stomach. (The recent decrease in SIDS cases in England has been credited to a campaign to get mothers to lay their babies down face up in cribs. ) This situation is made more dangerous by the use of waterproof (and thus airproof) bedding covers. There exist "safety pillows" with holes cut throughout, intended to allow breathing even when the sleeper is facedown. In one case of infant asphyxia, such a pillow was used—but covered with a plastic liner. 14

There have been rare, but well-documented, cases of infants being smothered by cats sitting on their faces or chests. In one instance a five-week-old baby was discovered in her baby carriage with a cat lying on her face. Her father got her breathing again with mouth-to-mouth resuscitation, but she died seven months later. Autopsy showed evidence of brain damage consistent with asphyxia. 15

Plastic bags, especially the thin, clinging sort used for garments, are notorious for smothering young children. Though flimsy, they tend to, well, cling. Older children and young adults are sometimes accidentally asphyxiated when sniffing fumes (glue, propane, solvents, etc.) from a plastic bag, if they become unconscious. This is in addition to the sometimes-serious toxicity caused by the vapor itself. In suicide, a small plastic bag is generally placed over the head and tied or taped around the neck. The oxygen in the bag is used up by rebreathing. This plastic bag technique, however, seems unreliable, since most gardenvariety bags are more-or-less easily torn in the course of convulsions or semiconscious movement. Plastic bag(s) or sheets may instead be wrapped tightly around the nose and mouth, which is faster, but more traumatic. A small bag is said to become unpleasantly warm; if so, some ice, wrapped in a towel and resting on the head or neck, should help. My experiments with larger bags have not found heat to be a problem, but one might as well be comfortable. A more gradual asphyxia can be achieved by use of a large plastic bag. A would-be suicide could combine drugs with this slow asphyxia to cause death less traumatically, more rapidly, and more reliably than either method could do alone. The seal around the neck doesn't need to be painfully tight—rubber bands, elastic, or Velcro will do—and small air leaks are not h

168 • G e o S t o n e

significant, at least in the thirty-gallon and tube tent sizes. In fact, there are examples of fatalities where the bottom of the bag was not closed at all. Interestingly, there is often no sign of asphyxia—the faces are pale and uncongested—after plastic-bag suicides. This may be important in assistedsuicide, where the assistant wishes to avoid legal entanglements. It also suggests that the mechanism of death is not always, or not entirely, hypoxia, but rather cardiac arrest set off by hypoxia. 16

17

The combination of asphyxia and drugs would decrease one of the major difficulties with drug overdose as a suicide method: Besides being unreliably lethal, most drugs take a long time, opening a suicide attempt subject to intervention. But if one were to use a drug(s) that quickly induced unconsciousness, simultaneous use of a large plastic bag or a tube tent would substantially increase the chance of a lethal result. (Obviously, this is counterproductive if one wants to survive the suicide attempt.) A n d the time-window for permanent injury would be smaller than with the drug alone: Done properly, if one were interrupted within, say, twenty minutes, there would be good chance of full recovery (since the drug dosage alone could be sublethal and there would be enough air for about a half an hour in a thirty-gallon bag); after an hour or so, it would be too late. However, there are some practical problems with combining plastic-bag asphyxia with drug overdose. For example, the huge number of available drugs and doses makes it difficult to know what and how much to use to achieve unconsciousness. In addition, the effects of drugs are somewhat uncertain for many reasons, among which are individual sensitivity and the possibility of vomiting part of the swallowed dose, and most oral drugs are unpredictable in how long they take to cause insensibility. Thus, simultaneous use of a small plastic bag might cause you to run out of oxygen while still conscious. This is not a big deal if you're alert—open the bag and try again—but may cause panic and bag tearing or removal during semiconscious movement. Waiting to use the bag until the drug(s) start to take effect does not seem like a entirely reliable alternative, but may be your best bet here, unless you have help available. 1

Multiple-bagging, thicker plastic, or wearing gloves will decrease the chance of tearing or removing the bag in the course of involuntary movements. If you are terminally i l l , you may have friends or family who are will-

Suicide and Attempted Suicide • 169 ing to assist by sealing the bag and restraining your hands after you lapse into unconsciousness; however, this involvement will lead to legal repercussions if discovered. Since thin plastic bag material tends to fall onto your face (especially if you're lying on your back), wearing a brim-hat or a dust (or painter's) mask (cut holes in it for easier breathing) is recommended. Most of these problems can be avoided by using a plastic tube tent instead of a small plastic bag: It's cooler, unlikely to drop onto your face, less critically dependent on drug speed, and will cause asphyxial death after roughly four to five hours. One could even build a coffin with an easily lifted lid. Having taken some unconsciousness-inducing drug, one might lie in the coffin, holding the lid open. Upon losing consciousness, the lid would fall, cutting off the air supply and leading to asphyxial death a few minutes later. If the drug dose was insufficient, or if, for any other reason, one woke unexpectedly, it would be an easy matter to open the lid. However, note that while the combination of sedative drugs and large plastic bag (or functional equivalent) might seem to allow time and opportunity to change your mind, as a practical matter such drugs will likely prevent you from making, or acting on, any coherent decision once they start to take effect. EXCLUSION OF OXYGEN

The effects of oxygen depletion have been described as consisting of four distinct stages. However, the following oxygen percentages are only approximate and vary from person to person. 18

1. Indifferent stage: Arterial blood is more than 90 percent saturated with oxygen; only effect is decreased night vision. 2. Compensatory stage: 82 to 90 percent oxygen saturation; body compensates by increase in heart and breathing rate. This level of oxygen saturation causes no additional difficulties in people in good health; those with heart, lung, or blood problems may show early symptoms of: 3. Disturbance stage: 64 to 82 percent oxygen saturation; increasing air hunger, headache, exhaustion, dizziness, confusion.

170 • Geo Stone 4. Critical stage: Less than 60 percent oxygen saturation; unconsciousness in a few minutes, followed by brain damage and death. This corresponds to 6 to 8 percent oxygen in the breathing mixture (normally 21 percent). Oxygen can become unavailable to the body by four general means: • It may be replaced by some nontoxic gas like helium; • It may be removed from the breathing mixture, either physically (for example, vacuum) or chemically (for example, used up by a flame); • Red blood cells may be prevented from picking up oxygen (for example, by carbon monoxide); • The ability of cells to use oxygen may be blocked (for example, by cyanide). Let's examine each of these in more detail. Many gases that are more or less nontoxic can cause asphyxia by replacing oxygen from the breathing mixture. Some common ones include acetylene, argon, butane, carbon dioxide, freon, helium, hydrogen, liquified petroleum gas ( L P G ) , methane, neon, nitrogen, and propane. As a result, they are dangerous in enclosed areas or when breathed through a gas mask, but not otherwise. People start showing signs of asphyxia when the concentration of these gases is around 30 percent; severe symptoms at around 50 percent; death at around 75 percent. DISPLACEMENT OF OXYGEN FROM THE BREATHING MIXTURE.

19

In the above list, argon, butane, carbon dioxide, freon, and LP gas are heavier than oxygen, and may displace it from the bottom of closed spaces, and, occasionally, even open spaces that are protected from wind. Tunnels that are open only through manhole covers occasionally contain lethal concentrations of carbon dioxide. Someone entering such a location unknowingly would become unconscious within a couple of minutes—perhaps within seconds —and would be dead after five to ten minutes. A standard gas mask is useless under these circumstances; supplemental oxygen is necessary. 20

Suicide and Attempted Suicide • 171 A mass asphyxia occurred near Lake Nyos, Cameroon, in August 1986. A large amount of cold, dissolved carbon dioxide exists in the bottom layers of this volcanic lake water. Probably as a result of turbulence from a mudslide, this carbon dioxide-rich water rose. As a result, the pressure on it from water above was decreased. The result was like opening a soft drink bottle: Bubbles of carbon dioxide gas left the water. People living in the valley below were engulfed by an invisible wave of carbon dioxide gas, which, being heavier than oxygen, displaced it. There was no warning. Everything that needed oxygen died within minutes: human beings, domestic and wild animals, even insects. Birds that were on the ground or flew too low perished. People dropped like flies (so did the flies) in the midst of whatever they were doing. The human death toll was more than 1,700. However, for the purpose of suicide, carbon dioxide would be an unpleasant choice, since its presence stimulates both breathing reflexes and the sensation of smothering. The hydrocarbons methane, butane, liquified petroleum gas ( L P G ) , and propane, while readily available as fuel gases, are normally mixed with badsmelling "warning" gases (mercaptans), related to skunk scents. Acetylene is used for gas welding and is easy to acquire, but contains somewhat-toxic acetone. Don't bother making your own acetylene from calcium carbide (formerly and still occasionally used in carbide lanterns for caving), because it contains an ammonia-like contaminant, phosphine cray. Freon are bad for the ozone layer and neon is expensive. Hydrogen is flammable (remember the Hindenberg) and raises the pitch of your voice. The remaining gases—argon, helium, and nitrogen—are your best bets in this category. They are all tasteless, odorless, nonirritating, and under these conditions, chemically and physiologically inert. In fact, nitrogen comprises about 80 percent and argon 1 percent of sea-level air, while a roughly 90 percent helium to 10 percent oxygen mix (precise ratio depends on dive depth) is used for deep-water diving (to avoid the intoxicating effects of high pressure nitrogen, called "nitrogen narcosis" or, more poetically, "rapture of the deep").

172 • Geo Stone Since these inert gases are not poisonous and your lungs have something to inhale, such asphyxias will be minimally traumatic. That is, they will not cause feelings of suffocation (which are due to carbon dioxide buildup, not the lack of oxygen) or hemorrhages (caused by high blood pressure from blocked jugular vein or struggling to breathe against a closed airway). 21

Most medical use of inert gases is for animal euthanasia, however there have been human fatalities from them, too. For example, airline face masks were mistakenly hooked up to inert gas cylinders instead of to oxygen at least ten times during the 1980s in the United States. The fact that these people died without attracting attention is consistent with nontraumatic death. Argon is commonly used for inert-gas electric welding and helium for balloons. Nitrogen has a variety of uses and may be purchased either as a gas or as a cold (-196 degrees C or -321 degrees F) liquid. A l l of these are available from industrial gas suppliers. Helium can also be found at party-supply stores, and argon at welding suppliers. None of these gases are dangerous^ unless they displace oxygen from the breathing mixture. Probably the easiest way to use inert gases for suicide is to enter a tube tent with a gas cylinder, flush the tent with any of the three gases, and seal the ends of the tube. The volume of a tent is such that you won't produce enough carbon dioxide to stimulate breathing reflexes before dying. Since there's little or no residual oxygen in the breathing mixture, minimal amounts of carbon dioxide ought to be exhaled, suggesting that a large inert gas-filled plastic bag over the head should work as well as the tube tent. 22

Only slightly more complicated method is to hook up a gas delivery mask (available at military surplus or medical supply stores) to a cylinder of compressed inert gas. This may, in fact, be the easiest method if you're using supplemental oxygen, and have a gas delivery system already in place. The main hazard of this (and all) asphyxia is the possibility of brain damage if the process is interrupted due to intervention, running out of gas, or tearing or removing the gas mask, plastic bag, or tube tent while unconscious. This can be minimized by using a high concentration of the anoxic gas, which causes most rapid loss of consciousness. These gases are not a danger to others in anything but a small, sealed space, however it's

Suicide and Attempted Suicide • 173 important that a gas cylinder not be mislabeled, lest it imperil subsequent users. In experiments, animals (dogs, cats, rabbits, mink, chickens) show little or no evidence of distress from inert gas asphyxia, become unconscious after one to two minutes, and die after about three to five minutes. Thus, use of any of these three gases, combined with a plastic bag, should be less traumatic than plastic bag asphyxia alone, since there will be little discomfort from carbon dioxide buildup and unconsciousness will be swift. k23

Oxygen can be removed either physically, by pumping it out along with the other components of air, or chemically, by combining it with other substances and so making it unavailable to the body. REMOVAL OF OXYGEN FROM THE BREATHING MIXTURE.

Physical removal of oxygen may become a means of suicide in the future, if there is space travel through the near-vacuum between planets. I'm not familiar with any use of hard vacuum to commit suicide on earth (though there at least one instance of suicide in a high-altitude test chamber). Don't try to become a footnote in the Guinness Book of World Records by being the first: If a vacuum was generated quickly, your blood would boil most unpleasantly from the low pressure before you had time to die from asphyxia. Using up the available oxygen is often the cause of accidental death, as when children are trapped in abandoned refrigerators and asphyxiate. Despite laws in every state and widespread publicity, the Consumer Product Safety Commission (CPSC) reported seventy-six of these deaths between 1980-88. 1

25

Similarly, glue sniffers who use plastic bags are at risk of unexpected unconsciousness, followed by death in the absence of prompt intervention. Rough calculations show that it's possible for much of the oxygen in a S C U B A tank to be used up if the inside of the tank rusts severely; so don't go diving with old air in your tanks. The same hazard exists in other iron tanks, such as ship's holds. Here, also, the damp steel walls can rust enough to use up the available oxygen. Such deaths tend to occur too quickly to be directly due to hypoxia; instead, the immediate cause seems to be sudden cardiac arrest, brought on by lack of oxygen.

CARBON-MONOXIDE POISONING

Until recently, in Europe you could open the oven gas valve (unlit), stick your head into the oven, and be fairly confident of dying quickly (Death from opening the stovetop valves was much slower since the entire room needed to reach a lethal gas concentration, unless your head was near the unlit burner.) Yet if you tried this in the United States, it would hardly ever work. The reason was that the United States and Europe used different gases for household heating. In the United States "natural" gas—composed largely of the nontoxic hydrocarbon methane—is cheap and plentiful; Western E u rope, until discovery of the North Sea oil and gas fields in the 1960s, had very little. In Europe, the gas generally used was a mixture of hydrogen, hydrocarbons, and (7 to 15 percent) carbon monoxide. The hydrogen is as nontoxic as methane, but carbon monoxide is deadly." This mixture was called "water gas" or "coal gas," and was a perfectly good fuel except for its deplorable tendency to kill anyone in the same (or sometimes even a nearby) room as a gas leak, deliberate or accidental. 1

As various parts of the world switched from a water gas-based mixture to natural gas (no carbon monoxide), the head-in-the-oven method of suicide became much less frequent. For example, between 1946 and 1996, the fraction of U.S. households using natural gas increased from 45 percent to 98 percent. During the same span, the household gas suicide rate decreased twelvefold, from 0.926 in 100,000 to 0.079 in 100,000. In England, the number of suicides due to gas fell from 2,368 (plus another thousand or so accidental deaths) to 11 between 1963 and 1978. Similarly, in West Germany the percentage of suicides by household gas fell from 11.6 to 0.3 percent from 1963 to 1976; meanwhile, however, the percentage of suicides due to drugs/poisons went from 24.4 to 36.5 percent. 26

11

It is possible that some Americans (including the poet Sylvia Plath ) who were familiar with low-lethality natural gas died by accident/mistake in E u rope when they intended a suicidal gesture with methane and died from carbon monoxide. This may also account for the common misconception that natural gas contains toxic amounts of carbon monoxide: It doesn't (though a misadjusted natural gas burner that produces a yellow or sooty flame is generating significant carbon monoxide).

Suicide and Attempted Suicide • 175 There was a bizarre case where a man tried to commit suicide by the headin-the-oven method. Since the gas was methane, this wasn't working well. After a while, the man got bored, took his head out, and lit a cigarette. The match ignited the gas-air mixture and he was killed by the explosion. The legally interesting question arose, was this a suicide or an accident? The inquest ruled it a suicide. 29

Household gas does have a bad smelling additive (methyl mercaptan) intended to warn you if there's a gas leak. This mercaptan is also added to bottled gas for the same purpose. However, old and internally corroded propane and butane tanks absorb the mercaptans, leaving an odorless explosive gas, which probably won't be detected if it leaks. A second factor that lowered the frequency of head-in-the-oven suicide attempts has been the general introduction of ovens containing thermocouples and either pilot lights or electronic igniters. Instead of manually lighting the oven with a match, these devices, unless disabled or defective, will light the oven moments after gas enters it. This makes gas asphyxia unlikely and substantially decreases the chance of an explosion caused by filling a room with an unburned gas mixture waiting only for a spark or flame to blow sky high. However, the stovetop burners will continue to emit gas if, for whatever reason, they fail to light or blow out. COMPARISON OF CARBON DIOXIDE, CARBON MONOXIDE, AND HYDROGEN CYANIDE: HOW Do THESE GASES WORK?

There's a lot of confusion concerning these poisonous gases. (Also see the chapter on drugs.) Carbon dioxide (CO ) is the product of the complete combustion of carbon by oxygen, and is nontoxic at low concentrations. Your exhaled breath is normally 4 to 5 percent C O . Inhaling CO does increase the acidity of your blood, and cause you to breathe faster, but at high CO concentrations these don't have time to become serious problems. 2

CO kills by two different mechanisms: (1) It displaces oxygen (and most other atmospheric gases, since carbon dioxide is denser than almost all of them), leaving you with nothing else to breathe. (2) Carbon dioxide in concentrations of 30 percent or more is also a rapid anesthetic, causing unconsciousness within one to two minutes, and death in about five minutes, without 2

176 • Geo Stone 30

much evidence of distress in experimental animals. It is widely used for theatrical fog (ever notice how it stays near the ground? and a good thing, too) and as a portable refrigerant in its frozen state, dry ice. There is at least one case report of a death from transporting dry ice in an enclosed car. As the dry ice evaporated, a dangerous concentration of gaseous carbon dioxide was created. In addition to dry ice, CO also is available as a compressed gas. (You need a special CO valve for these tanks, as standard valves freeze up.) Carbon dioxide gas has the further merit of being nonexplosive and cheap and can be made at home by mixing baking soda and vinegar. 2

2

Carbon monoxide (CO) is colorless, odorless, and tasteless; it has one less oxygen atom than carbon dioxide ( C O ) . It will be produced by any carbonfueled flame that doesn't get enough oxygen. If a flame is yellow or puts out visible soot, you can be sure it's also generating carbon monoxide; if a flame is blue, carbon dioxide is the principal carbon oxide. You may have noticed that the outer part of a candle flame is blue, while the inside is yellow. This is because the outer portion burns hotter due to its greater oxygen supply. Carbon monoxide's biological effects are mostly due to the fact that it's 200 to 250 times more strongly attached to the oxygen-transporting molecule in red blood cells, hemoglobin, than is oxygen. A n d a hemoglobin molecule can't carry both carbon monoxide and oxygen. Thus a low concentration of CO in the air can occupy a large fraction of your hemoglobin. For example, 0.01, 0.02, 0.10 and 1.0 percent CO in the breathing mixture would tie up 11,19, 54, and 92 percent, respectively, of a person's hemoglobin at equilibrium. 2

31

Carbon monoxide is also directly toxic to cells by interfering with their ability to use oxygen, by binding to a number of iron-containing enzymes and other proteins. Carbon monoxide causes blood to be a bright, cherry red, which produces a ruddy corpse. This unusual coloration can be used for preliminary identification of CO poisoning. The toxicity of carbon monoxide is shown by a case in which a car accident victim was put on a stretcher, which was placed eight to ten feet behind the tailpipe of an idling ambulance while another person was attended to. Upon reaching the hospital, the first man was discovered to be dead from carbon-monoxide poisoning. His other injuries were minor. Since smoldering tobacco contains about 4 percent carbon monoxide, pack-a-day smokers have 5 to 6 percent of their hemoglobin tied up by car32

Suicide and Attempted Suicide • 177 bon monoxide. This level causes small, but measurable, impairment of both physical and mental performance. Frequent cigar smokers have peak carbon monoxide blood levels of around 20 percent. A 50 percent carbon monoxide blood level is often fatal, but levels as low as 15 percent may also kill those with heart or lung problems. 33

34

35

It takes about five and a half hours of breathing fresh air to remove half the carbon monoxide from hemoglobin, another way of showing the high affinity between the two; 100 percent oxygen reduces this to 80 minutes; 100 percent oxygen at three atmospheres pressure gets rid of half the carbon monoxide in twenty-three minutes, but may cause permanent eye damage. However, even twenty-three minutes is often too long: A few minutes of asphyxia is enough to cause brain damage which may be fatal, and has a good chance of being permanent. 36

These injuries include dementia, psychosis, paralysis, cortical blindness, memory deficits, and Parkinsonism; the latter two are the most common. The frequency of permanent injury from carbon-monoxide overdose ranges from 0.3 to 43 percent in various studies, even if high-pressure oxygen used. "Some survive [in] a coma for weeks or months before succumbing to infection." 37

38

Alcohol and other central nervous system depressants (for example, sedatives) may increase the toxic effects of carbon monoxide. A 0.20 percent blood-alcohol concentration combined with a serious (but generally not fatal in a healthy individual) 35 to 40 percent carbon-monoxide saturation of the blood has been fatal. However, this is association is controversial. Carbon monoxide is also hazardous to unprotected rescuers, and will explode i f the concentration reaches 10 percent and there is a spark or flame present. This concentration will not be reached from combustion, but may be achieved from compressed CO (in tanks) or chemically generated C O . Automotive carbon monoxide poisoning is becoming less frequent in the United States. The reason is that car engines are required to get better gas mileage and produce fewer toxic emissions than in the recent past. A new, well-tuned engine may emit 0.06 percent carbon monoxide, compared to 6 to 9 percent from an engine of the 1960s, a hundredfold decrease. As a result, it takes longer to kill yourself by filling a garage with carbon 39

40

178 • Geo Stone monoxide from a tuned engine. It can be done, but is no longer either fast or certain. How long does this take? For a given-volume garage, it depends primarily on the age, state-of-tune, and size of the engine. If a "clean" two-liter engine idles at 750 rpm, then it will take about an hour for 20 by 20 by 8 foot garage to reach 0.06 percent carbon monoxide. This is not a reliably lethal concentration. What would happen if the exhaust gases are piped directly into the car, as is commonly done using a garden or vacuum-cleaner hose? It would take about three minutes to reach 0.06 percent atmospheric carbon monoxide. However, the atmospheric CO concentration can't be greater than that of the exhaust mixture; it just takes less time to get there. Once again, not reliably lethal. If we had a "dirty" engine of the same size with 6 percent carbon-monoxide emissions (100x clean engine), it would take about thirty-five seconds for the garage to reach 0.06 percent carbon monoxide; 70 seconds for 0.12 percent, 140 seconds for 0.24 percent, and so on. Thus, a lethal concentration of CO would be produced in a minute or two. Death could occur in less than a half an hour. Note that, while running such exhaust into the car would generate a lethal concentration of CO within a few seconds, one would have to continue breathing it for a fatal result. These calculations are illustrative rather than precise because (a) garages differ widely in size and airtightness; (b) most cars emit somewhere between 0.06 and 6 percent C O . Alternatively, one may be able to buy a small tank of carbon monoxide from a chemical, science supply, or industrial gas supply company (you will need a gas regulator/valve, too). Loosely sealing yourself in a plastic tube tent, car, or functional equivalent, and releasing the gas should be quickly (five to fifteen minutes) fatal. A simple and reliably lethal source of carbon monoxide is a charcoal grill, hibachi, or other burner. If charcoal (or any other handy carbon fuel, like wood or coal) is burned in one, a deadly CO concentration will be quickly generated in any small, enclosed space, such as a tent. Using this method i n side a building is a bad idea, both due to fire hazard and because of the CO danger to other people. 0

Dr. Kevorkian's current suicide apparatus consists of a gas mask attached

Suicide and Attempted Suicide • 179 to a tank of carbon monoxide. The gas flow is controlled by a valve that is opened by the patient, who is wearing the mask. Under these conditions, death should occur in less than five minutes. The advantage is that the gas concentration will probably be higher than with a tent, with faster results. The disadvantage is that the hookup is a bit more elaborate and is correspondingly more likely to require someone else's help. EFFECTS OF CARBON MONOXIDE

A century ago the eminent British scientist J. B. S. Haldane studied the effects of carbon monoxide on himself—a time-honored, but sometimes hazardous, medical tradition. While sitting and taking notes, he breathed a 0.21 percent carbon monoxide mixture for seventy-one minutes. A summary of his observations follows: After twenty to thirty-four minutes he had a slight feeling of fullness and a throbbing of the head; 17 percent of his blood hemoglobin was tied up by carbon monoxide as carboxyhemoglobin. After forty to forty-five minutes the headache was worse, his breathing was slightly fast and he felt abnormal (39 percent carboxyhemoglobin). After fifty-nine to sixty-five minutes, he was breathing fast, looked pale, was starting to become confused, and couldn't move in his chair without feeling worse (44.5 percent carboxyhemoglobin). After seventy-one minutes his v i sion was dim, he couldn't get up without help, and he stopped the experiment (49 percent carboxyhemoglobin). There were no long-term i l l effects. 41

As always, there is individual variability: In 7 percent of fatal CO poisonings, less than 40 percent of the victim's hemoglobin was tied up by C O . Another study found that 0.32 percent CO for an hour caused unconsciousness; 0.45 percent caused death. 4 2

43

In animal experiments, carbon monoxide is about as fast as inert gases: unconsciousness occurs in one to two minutes and death after around five minutes, using 4 to 8 percent C O . Death is preceded by convulsions and muscle spasms, but the fact that there are frequent accidental carbon monoxide poisonings among sleeping people shows that it doesn't cause enough discomfort to reliably awaken someone. However, first taking enough of a sedative (for example, alcohol, opiate, barbiturate) to achieve unconsciousness would probably result in an easier death. 4 4

If low concentration of CO is anticipated, such as from new car exhaust, it may be useful to premedicate with antinausea (for example, some antihistamines) and antiseizure (for example, Valium) drugs, but this is speculative. Better is to avoid this situation: Don't use CO for a suicidal gesture and don't use low concentrations for suicide. We close this section with a suicide note from Japan, written while a car 45

was filling with carbon monoxide. The first eleven items of the note were personal messages and instructions for the disposal of assets. The last entries are quoted below, in translation: 12. I had attempted suicide with several methods, I could not commit it yesterday. I hope I am successful in killing myself today. 13. I have written too much. Finally, good-bye my life! I believe in Rin-ne [Buddhist concept of reincarnation as human or animal, depending on one's conduct in the most recent life.] [At 6:15 p.m.] The inhalation of exhaust gases is begun. [After seven minutes] My eyes and throat are slightly irritated. Put on a bathing towel.There are tremendous water drops on the door glasses [This is condensation of water vapor from the exhaust].The tank is full of gasoline. [After eight and one-half minutes] Slight shortness of breath. Haha-ha.The powers of Nissan's engine are great! [After ten minutes] Swallowed a cup of Japanese sake [rice wine]. I could not control myself to stay in the cabin [of the minivan] at this level of shortness-of-breath yesterday. [After eleven minutes] To the mistress of a grocery store: "Yes, you were right.The size of this hose, 30mm in outer diameter and 25mm in inner diameter, fits the exhaust pipe perfectly. [After twelve and one-half minutes] Swallowed another cup of sake. I wish I could have a can of beer. I wonder what the concentration of carbon monoxide is now. [After fourteen minutes] Breathing can only be done by mouth. [After fifteen minutes] Water is pouring out of the hose.

Suicide and Attempted Suicide • 181

[After sixteen minutes] Good-bye, Mum and Papa! [and a list of six people].

[After seventeen minutes] Still I am living. It is asthmatic breathing. Now, I will sleep.

This was the last entry. Cyanide is one of the fastest-acting poisons (see the chapter on drugs for more information), though sources differ with regard to just how long (mostly between one and fifteen minutes in large (1500 mg) doses, longer with lower doses ) it takes to kill. The lethal dose is estimated to be 50 to 300 mg; however much larger amounts have been survived with prompt medical attention. 46

47

The gaseous forms, hydrogen cyanide and cyanogen, are rarely used in suicide, but should act more quickly than the oral poison; solid cyanide salts (potassium, sodium, and calcium cyanide) are the commonly sold forms, but hydrogen cyanide gas can be easily made by mixing a solid cyanide and a liquid acid (for example, hydrochloric [muriatic] acid); this is what is done in gas chambers. Cyanide works by causing asphyxia at the cellular level; it binds to iron ions found in some enzymes and makes them unavailable for cellular respiration, essentially choking your cells. The cells try to survive by switching to a non-oxygen requiring metabolic pathway (the same one your muscles use when you're exercising faster than you can breathe in oxygen), but this quickly builds up lactic acid to toxic levels. The fastest-metabolizing cells, brain and heart cells, are most quickly affected; and if they die, so do you. Cyanide also has a direct poisonous effect on the central nervous system and depresses breathing, but this is overkill. As with carbon monoxide, some survivors have permanent nervous-system injury, such as memory deficits and tremor. If you use cyanide, it would be a thoughtful gesture to leave a conspicuous note to that effect, because of possible hazard to rescuers who might otherwise apply mouth-to-mouth resuscitation—some people lack the ability to detect the almond-like smell of cyanide. Thus, all three substances, carbon dioxide, carbon monoxide, and cyanide

182 • Geo Stone are asphyxiants: Carbon dioxide displaces oxygen, keeping it from getting to your lungs; carbon monoxide prevents your red blood cells from picking up oxygen and also blocks cellular respiration directly; and cyanide stops your cells from "breathing" despite plenty of available oxygen in the air and in your red blood cells.

SUMMARY

1. None of the methods discussed in this chapter should be used for a suicidal gesture; all are potentially lethal and don't give enough warning of unconsciousness to allow you to count on being able to change your mind. 2. Strangulation, like hanging, is quickly fatal. If the front (throat/airway/trachea) part of the neck is well-protected, it should not be particularly painful. Protecting the left side of the neck will minimize compression of the jugular vein and subsequent engorgement of the head with blood. For someone who is terminally i l l , has no help available, and is bedridden, strangulation may provide the best combination of speed, ease of application, and lethality. 3. Carbon monoxide is probably the only readily available toxic gas worth considering for suicide, but internal combustion engines are highly variable as sources for this gas. This is relevant either if you are contemplating filling a garage with a lethal carbon-monoxide concentration or running a hose from the exhaust pipe into a sealed car. At the same time, carbon monoxide is both slower and probably more subject to interruption than hanging or strangulation, and has caused brain damage in some survivors. 4. Perhaps the least traumatic of these methods consists of achieving unconsciousness with drugs, combined with plastic-bag, carbon monoxide, or inert gas asphyxia. However, this requires arranging and coordinating two methods, which may be difficult to do without help, particularly for people who are severely i l l . Finding the right drug(s)/doses is also sometimes a problem. In the absence of sedative drugs, either carbon monoxide or inert gas (nitrogen, helium, or argon) will probably make plastic-bag asphyxia less unpleasant since they speed unconsciousness and minimize carbon dioxide buildup.

18 CUTTING AND STABBING

I decided I'd better use the bathroom because from what I'd read, that's where everyone kills themselves. Plus if I got the bedroom rug dirty my mother would kill me. Then I just started. I cut my wrists. I watched the blood go into the sink, and because the sink was already wet, the blood spread out and I realized how neat it looked. It hurt, but I didn't mind. It was almost as if I wanted it to hurt because I wanted to be tough. Everything in the bathroom is white. White tile walls and white tile floors. I had to keep stopping and cleaning up because I didn't want to make a mess. I poured water in the sink so the blood would go down the drain. I'd rest my arms on my pants to soak up the blood so it wouldn't get on the floor 1

Relatively few people commit suicide by cutting or stabbing themselves. However, around 10 to 15 percent of suicidal gestures/attempts are from wrist cutting. Unlike all-or-nothing methods like hanging and drowning, cutting and stabbing can be made about as lethal as you choose to make it. Nevertheless, mistakes and accidents do happen. a2

Suicide and Attempted Suicide • 187 NATIONALITY. In recent years, about four to five hundred (1.4 to 1.7 percent) of the roughly thirty-thousand suicides in the United States each year die of self-inflicted cuts or stabs. The frequency of cutting and stabbing seems to vary less from country to country than do some other methods, such as gunshot or drowning. For example, cuts/stabs was the method used by 2.25 percent of Swedish suicides between 1973 and 1984, 3 percent in Great Britain between 1975 and 1987, and 1.7 percent of Japanese suicides between 1959 and 1970. 3

AGE. In the United States, cut/stab suicide rates increase steadily with age, unlike the overall rate, which is remarkably steady between the ages of twenty to twenty-four and fifty-five to sixty-four. This mostly reflects the pattern of white male suicide, which swamps female and nonwhite suicide numbers. RACE. Whites have about twice the overall suicide rate as blacks, and also twice the cut/stab rate. SEX. M e n killed themselves by cutting/stabbing at a rate about 4.8 times that of women in 1994, which is a bit more than the overall male to female ( M / F ) suicide ratio of 4.2 to 1. Thus a slightly higher proportion of suicidal men than women killed themselves by cuts or stabs in that year. However, these ratios vary from year to year. The sixteen-year (1979-94) M / F ratio average was 3.6 to 1, similar to the overall suicide ratio of 3.8 to 1 (21.21 in 100,000 for males compared to 5.61 in 100,000 for females). A comparable sex ratio in cut/stab suicides was also seen in Sweden (3.67 males to 1 female) between 1973 and 1984 and Japan (3.4 to 1) from 1948 to 1955. While these data have a surface similarity, the distribution of suicide methods in Sweden and Japan is strikingly different from that in the United States. For example, guns and explosives caused 65 percent of the male and 40 percent of the female suicidal deaths ( M / F ratio of 6 to 1) in the United States, but 16 percent of the male and just 1 percent of the female deaths ( M / F ratio of 40 to 1) in Sweden. Swedes preferred drugs/poisons, drowning, jumping, and asphyxia. In addition, styles change; the Japanese M / F ratio dropped to 2 to 1 for the years 1959 to 1970. MOTIVES. U.S. national suicide data don't address motive, so we turn for details to a study from Sweden. This information may be helpful in drawing a picture of some people who killed themselves with sharp objects; however, 6

It's curious that all of the emotional loss or social-motive suicides were by men. Eleven of the 89 (nine in the "known mental illness" group) were known to have made a sucide attempt within the six months prior to their deaths; five of these were within eight days of the fatal attempt. Nine of the eleven had taken a drug overdose in their earlier bid; one had tried hanging, one had used "sharp force" (presumably cutting or stabbing). The seriousness of these efforts is not reported, but both cutting and drugs are often considered "ambiguous" methods in the suicide literature, because of their low death rates. However, this is only the case in the aggregate: Some overdose or sharp force suicide attempts are deadly serious, some are calls for help, some are a toss of the dice. A knife blade through the heart is every bit as lethal as a bullet in the head. Most of the "mental illness" suicides occurred several years after diagnosis, and in fifteen of the twenty-two cases the patients killed themselves less than a week after the last treatment session. The nature of these "treatments"

Suicide and Attempted Suicide • 189 (psychotherapy, drugs, etc.) is not specified in the article. Among this same group of twenty-two there were seven alcohol addicts, two addicted to other drugs, and two to both alcohol and other drugs. The authors point out that only one of these eleven people repeated their previous method. However, this should not be surprising, since (a) drug overdose is used in a majority of all survived suicide attempts, and (b) people intending to kill themselves might understandably choose a method different from one which they had survived. On the other hand, people who carry out a series of suicide attempts/gestures tend to repeat their earlier methods. 9

REPEATED SELF-CUTTING. Some people have a history of cutting themselves. A majority of repeated self-cutters are young, single, and female. They usually have interpersonal or psychiatric problems, though not necessarily severe ones; rather, they're prone to wide mood swings in response to stress, most often rejection, either real or imagined. Investigators claim that cutting releases this tension and returns them to reality, at least for a while; suicide is rarely intended. Around 70 percent of cutters also have eating disorders: anorexia and/or bulemia. 10

There is a phenomenon seemingly related to self-cutting called carving, where people cut scarring wounds, often, but not always, on their wrists. Usually names, initials (people who go through lots of boy/girlfriends may look like palimpsests), or symbols (crosses are popular, as are names of rock groups) are carved. These cuts, generally done by teenagers, are sometimes confused with suicidal-gesture wrist cutting but are a form of scarification more akin to tattooing. This is not to say that a disproportionate number of carvers don't commit suicidal gestures; they do. But they seem to mostly use medicine overdoses, at least among girls. CARVING.

11

Carving, except in this subculture, is generally seen as pathological. However this may be a parochial view: In addition to contemporary cosmetic plastic surgery, there are, numerous examples of the widespread human interest in hand-crafting the body which ranges from head-moulding in ancient Egypt, Central and N o r t h America and modern Europe, to Chinese foot-binding, which produced feet that were so small

190 • Geo Stone they could not bear their owner unsupported. Other types of anatomical rearrangement in the list include trepanation of the skull (worldwide, prehistoric), finger amputation (Pacific, Africa), and various types of genital rearrangement (Australia, Africa). In fact, [the author of the book cited] concludes that only the eyes and the anus have never been the target of socially sanctioned mutilation.... "Such practices fill many Westerners with horror although, it must be said, Western practices of ear- and nose-piercing, circumcision, and skin-bronzing through radiation exposure are rarely abhorred with equal vigour." 12

How DANGEROUS ARE CUTTING AND STABBING WOUNDS? Cutting/stabbing looks like one of the safer methods for a suicidal gesture because it has the lowest fatality rate, 4.1 to 5.8 percent. It also has the lowest ratio of fatal to nonfatal injury. It would thus seem to be the "least serious" method. (See Tables 16.1 through 16.4.) However, as mentioned earlier, all these data combine people intending to die with those wanting help or attention. As a result, they overestimate the danger of cutting as a suicidal gesture and severely underestimate the likelihood of death for those really trying to kill themselves. Cutting and stabbing is used by both groups because, unlike most other methods of self-harm, one can—roughly—predict the degree of injury from a given cut; such graded injury is hard to arrange in, say, drowning or hanging. Generally speaking, the people who cut themselves as a cry for help tend to be younger and female; those who mean to die are more likely to be middleaged and male.

METHODS SUICIDAL CUTS

Cutting the throat is the fastest, most reliably lethal, and perhaps most gruesome of suicidal cuts. However the method is not used as often as formerly, probably because straight razors have been widely replaced by safety razors and electric shavers. THROAT.

Suicide and Attempted Suicide • 191 The cut-throat wound usually starts high and (in right-handed persons) on the left side of the neck, goes across the center, and ends lower on the right side. (You might try this—with your finger—to get a better sense of it.) Since the "victim" generally throws his head back, the skin will be under tension and the cut smooth and straight. This may not be the case when the skin is too loose to be effectively stretched tight, as in old age or after recent major weight loss. While most cuts are by razor or knife blade, occasionally broken glass or some other irregular object is used. These also tend to leave jagged rather than straight wounds. More often than with other methods, the corpse is found in front of a mirror. Perhaps mirrors are used to visually guide the hand. Shallow cuts are often found near the beginning of the wound. These are one piece of evidence a medical examiner will use to distinguish suicide from murder. However, hesitation cuts are occasionally seen in murder, and therefore are not definitive. Other hesitation cuts are shallow, more or less parallel gashes inflicted before, or in the process of, achieving enough courage for the final wound. These are often seen in wrist cuts. In one study, hesitation/tentative cuts were seen in 80 percent of fatalities; in 20 percent, one resolute cut or stab was sufficient. It's very rare that the back rather than the front of the neck is the target. In one case, however, "A butcher, who had failed to commit suicide by the usual incision, succeeded on a later occasion by adopting the incision, at the back of the neck, which he was accustomed to use when slaughtering animals." 13

14

Sometimes, when another method is not working fast enough, an impatient or desperate person will slash his throat: "A man aged thirty-three ingested a quantity of aspirin. He was found dead in his garage with a superficial cut on his right wrist and a deep cut on his left wrist. There was an incised wound three inches long on the right side of his neck accompanied by tentative, superficial cuts. The major blood vessels were spared but he had severed the right anterior jugular vein." He had taken approximately twenty-five tablets of aspirin. Though these had caused significant bleeding in his stomach, it is not a normally dangerous dose in a healthy adult, as he would have known had he read this book. 15

192 • Geo Stone WRIST, ELBOW, ANKLE. Cuts on the wrist, and to a much lesser extent elbow or ankle, are often used to make a suicidal gesture. Such wrist cuts are generally shallow and perpendicular to the long bones of the forearm. They tend to sever the surface veins. Since these veins are not particularly large and do not carry as much pressure as the arteries, such cuts are not usually lifethreatening because they can clot before a fatal quantity of blood is lost. Wrist cuts become more dangerous:

1. If the cuts are more or less parallel to the long bones. In such cases the blood vessels tend to be sliced lengthwise or diagonally, making clotting more difficult and thus allowing more and faster blood loss. 2. If cuts are deeper and near the long bones of the forearm (the thumbside long bone is the radius; the other long bone is the ulna), they may sever the radial artery or the ulnar artery. These pieces of plumbing are under high pressure and cutting them can be fatal unless the bleeding is actively stanched. There are claims that a single cut across a healthy wrist artery is not dangerous, because the cut artery (which, unlike veins, has built-in muscle) will contract and so limit blood loss. While this protective mechanism does exist, it's not always sufficient: Four of the forty Stockholm deaths due to cuts on the limbs were from just such an injury. 16

You can find (or usually avoid) these arteries by checking various points around your wrist for a pulse. Without a stethoscope you will only detect one in a couple of spots, for example, where your wrist and thumb come together. You can locate the radial artery fairly near the surface there. The other major wrist artery, the ulnar, runs parallel to the other forearm bone and can be felt near the heel of the hand. Hyperextending the wrist is common, but hides the radial artery around the end of the radius (try feeling for the pulse), and one may end up with only severed flexor tendons. 3. If cuts are numerous. Multiple cuts of wrists, elbows, and ankles, none individually dangerous, may cause enough blood loss to be fatal. 4. If clotting is inhibited. This may be deliberately done by keeping the cut under water. Another way to slow clotting is with drugs. Some drugs, like heparin and coumarin-like compounds, are prescribed specifically to decrease blood clotting in medical conditions like stroke. W i t h other drugs, 0

Suicide and Attempted Suicide • 193 the anticlotting ability is usually considered a side effect to its intended therapeutic use. Aspirin, when taken for pain relief, is the most common drug of this sort. Since many people are not aware of these effects, use of such drugs may occasionally turn a suicidal gesture into an accidental suicide. FEMORAL ARTERY AND VEIN. The femorals are the main arteries and veins to and from the legs. As you might expect, they carry a lot of blood, and an untreated cut to either one is quickly fatal. In one case, a thirty-four-year-old man bled to death from a 2 millimeter (less than Vs inch) nick to the femoral vein—and the vein is the low-pressure half of the circuit. They run next to each other, with the artery closer to the front of the leg, and are nearest to the skin at the groin, which makes a tourniquet hard to apply if that's the site of the cut. While knives can be and often are used on impulse, one case showed the benefits, however temporary, of planning and knowledge. A physician applied a local anesthetic to his leg, and then neatly cut his right femoral artery lengthwise. 1 estimate that he would have lost a fatal amount of blood in about five minutes. He died quickly, and, probably, painlessly. 17

18

STAB WOUNDS. Unlike most wrist cuts, self-inflicted stab wounds are generally intended to be lethal. They are usually aimed at the front of the trunk, with the heart area being the most frequent target. Other sites tend to be scattered near the centerline of the chest, from the neck to the groin; they are almost never seen on the head, back, or extremities. Death, when it occurs, is generally due to loss of blood if a major vein or artery is cut, or to heart damage, if that vital organ is cut. A heart injury, in turn, causes internal bleeding and/or an inability to pump blood to other parts of the body. Even a relatively small heart wound may be fatal if not promptly repaired, but the severity of a heart wound also depends on its location. If the cut is to the upper chambers, the right ventricle, or the major blood vessels, death is likely; a small cut to the left ventricle wall is sometimes survived, since the thick muscle there may seal the wound when the heart contracts. However, this is not something you should count on. 19

There are occasional reports of unusual sites or methods. One woman cut off her arm just below the shoulder, using a small kitchen knife with a six-inch blade. Another held a knife to her back and ran backOTHER WOUNDS.

wards into a wall. One man stabbed himself in the chest with a chainsaw while it was running. 21

LOCATION AND NUMBER OF WOUNDS In the previously mentioned eighty-nine Swedish suicides, the most common sites were wrists, throat, and heart area; less frequently chosen were the inside of the elbow and the abdomen. There were no wounds of the head, face, shoulders, or back, and very few of the legs. In forty people the only injuries were to the arms and/or legs; in four of these a single cut of the radial and/or ulnar artery caused fatal hemorrhage. The chest area was the target of thirty-four people, but there were often additional injury sites. W i t h five of these thirty-four, such force was used that the sternal (breast) bone or ribs were cut through. This requires a good deal of pressure. Most of the other thrusts in this region went between the ribs; only three were blocked by them, thus requiring a second site. If bones are missed, little strength is needed: "The skin offered a little resistance, but that being overcome, the blade went deep into the chest with alarming ease." 22

This is not to say that multiple cuts or stabs were rare. Quite the contrary. Thirty-four of the forty suicides with injury only to arms and legs had multiple cuts. In deaths that included chest or abdominal stabs, only nine of thirty-one were from single thrusts. One person stabbed himself in the chest area over the heart fifteen times. Ten of these went through the chest wall but only one pierced the heart; the others were too low. The largest number of stab wounds in and by a single person was thirty-one, by a twenty-eightyear-old woman who probably was hyperactive due to thyroid disease. Suicidal stab (as opposed to cut) wounds to the neck are unusual. One i n stance was by, a labourer aged fifty-eight who for two years had suffered from emphysema; during the seven weeks prior to his death his condition had worsened and he had been unable to work he slept downstairs. On the day of his death his wife had left the house to go shopping at 10:30 A.M. She left him in bed and locked both of the house doors. On her return, an hour later he was not in his bed;

Suicide and Attempted Suicide • 195 she thought he had gone upstairs to dress. Since he did not appear and she heard no sounds of movement she went upstairs to find him. He lay dead on the floor and had fixed a "suicide note" on the door (She identified the writing as that of her husband.) The man lay on the floor fully clothed. The handle of a knife protruded from the right side of his neck and the point emerged by 1/4 inch on the left side. There had been no struggle and no one had entered the house. The knife was nine inches, and its blade was 4 3/4 inches long. It had entered the neck an inch below the lower jaw on the right side and emerged 1 1/2 inches below the external opening of the left ear.. T h e blade had severed the right sterno-mastoid muscle, right common carotid artery and internal jugular vein. 23

SUICIDE, HOMICIDE, OR ACCIDENT? How does a medical examiner determine if a cut or stab wound is self-inflicted? Since a blade is generally held differently in suicide and homicide, the resulting wounds tend to be different. For example, in homicides, threefourths of stab wounds to the heart are vertical or slant upwards and to the right; among suicides only one-fifth have those characteristics. 24

Similarly, in sixty-five of the sixty-nine suicides (94 percent) where information was available, clothing had been removed or pushed aside from the target site prior to the injury. This is similar to the situation found in suicidal gunshot wounds, but differs from most homicidal cuts and stabs. In homicide, since the skin is not normally stretched, a cut tends to be more jagged than in suicide. Instantaneous rigor is the immediate stiffening of the body occasionally seen in cases of quick and traumatic death. If the fatal weapon is found firmly held in the victim's hand, that weapon was held at the time of death and is very strong evidence of suicide. Gunshot and a cut throat are two suicidal methods in which instantaneous rigor is occasionally seen. This phenomenon is infrequent, its mechanism is unknown, even its existence is disputed, and there are no known instances of it being successfully simulated after a homicide. Obviously, injury to a site that can't be reached by the victim argues

196 • G e o S t o n e

strongly against suicide, but there are rare instances of suicides imitating a homicidal wound, for example, the previously mentioned knife-in-the-back case. Similarly, if there are many potentially fatal wounds, suicide is unlikely. Multiple severe stab wounds are common in homicides. This "overkill" may be due to rage or to wanting to be sure that a lethal stab was administered or to expedite the death of the victim. There are enough other differences that it is unlikely that a competent medical examiner will be fooled into confusing the cutting and stabbing of suicide with simulated suicide (murder). Fatal cuts and stabs that are accidental are rare but fascinating. In one such case, a woman was seen carrying ducklings in a box covered by a piece of glass. She reached a fence and collapsed. By the time medical help arrived, she was dead. She had apparently shattered the glass against the fence and a shard had penetrated her chest and heart. A piece of glass that fit the wound was found nearby, and there was a fresh cut on her finger that probably occurred when she pulled the glass dagger out of her heart. Another case was a medical whodunit: d25

While the Deblin, a Polish ship, was sailing ... in international waters, a member of the crew was found lying injured on the starboard side; he lay in a space between the superstructure and deck cargo. Blood was freely distributed on the deck and adjacent parts of the ship in the form of pools and some splashes.The appearances were those of venous rather than arterial bleeding. He was carried below and laid in his bunk. The Captain summoned a doctor from Grimsby [England] but by the time he had boarded the ship the patient had died. Inspection of the body disclosed a stab wound in the left groin; it was deemed to have been homicidal. The police were summoned when the ship docked in Hull and the crew were submitted to interrogation. O n e member whom they wished to interview had locked himself in his cabin and refused to see them. In another cabin they found freshly washed outer garments and a red-brown stain on the cabin door. At this juncture the atmosphere was distinctly tense. The postmortem examination confirmed the presence of a

Suicide and Attempted Suicide • 197 punctured wound in the left groin. Its course was upwards and backwards. It was elliptical but had a small secondary side cut at its inner end. Nearby, on the outer side of the wound there were two superficial abrasions. He also had a laceration under his chin and a scratch above his left eyebrow. Dissection demonstrated a pointed fragment of glass in the thigh wound.The front of the femoral vein had been punctured and opened for a distance of one third of its circumference; the femoral artery was intact.The blood in the deck had come, in the main, from the injured femoral vein. Inspection of the clothing disclosed several fragments of glass in the left-hand trouser pocket. Some of these bore pieces of the label of a bottle of vodka. Several of the fragments were sharply pointed and dagger-like. There was a recent cut in the lining of the pocket, and trouser leg. 6

This was the result of an accident. He had been below drinking with friends and had gone on deck to get more drink for the party. He was not drunk but might have been under the influence of drink. On his way back to the party he had put a bottle of vodka in the left-hand pocket of his trousers. W h e n on deck, either because of his condition or because the ship had suddenly pitched or rolled, he had fallen. In consequence the bottle of vodka was shattered and one of the fragments had punctured his thigh. He had also struck his chin during the fall. 26

A n d thus an international incident was averted. Often a difficult case arises from a single stab wound sustained in a fight. The defense frequently makes the claim that the victim ran onto the blade. The medical examiner must then consider the angle of the wound, presence or absence of defense wounds on the hand and arms, and other such factors. In one instance of this sort, analysis of the deceased's clothes showed that the knife hole in his jacket was lower than that in his shirt, which was lower than the wound in his body. There were also two knife holes in the vest. This pattern is inconsistent with running onto a blade, but quite consistent with being held by the shoulder, and thus having the clothing pulled upwards at the moment of the stabbing. Guilty. 27

198 • Geo Stone 28

We close this side tour with an unusual murder from 1978. Georgi Markov was a forty-five-year-old Bulgarian political exile and dissident living in London. He had defected from Bulgaria in 1971, and began to broadcast a mix of satire and criticism home on the B B C World Service. On September 7, while waiting for a bus, he felt a sharp jab in the back of his right thigh. Looking around, he saw a man who mumbled an apology, dropped an umbrella and hopped into a waiting taxi. Within a few hours Markov was i l l and had a fever. His condition worsened and he was hospitalized the next day. He continued to deteriorate and died three days later. Autopsy found a platinum-iridium (a noncorroding alloy, stronger than steel) ball in the center of the inflamed area on the back of his thigh. It was about the size of a pinhead and had two channels drilled into it. The ball had been spring-loaded in the sharpened tip of the abandoned umbrella, and was used to administer poison, carried in the tiny holes. The poison was never directly identified. In a curious way, this helped i m plicate ricin (a toxic protein extracted from castor beans), because ricin is broken down in the body after doing its damage, and since virtually nothing else would have killed in such small dosage. The Bulgarian secret police were thought to be responsible. Later information confirmed the identities of both the perpetrators and the poison. 29

f

CAUSE OF DEATH

A cut-throat wound most often causes death by hemorrhage. Severing either of the two carotid arteries on the right side of the neck or the jugular veins on the left will cause fatal blood loss within about five minutes. Since blood flows into the head via the carotid, unconsciousness might occur a couple of minutes after cutting it; perhaps a minute or two longer if the jugular veins are sliced instead. Since the trachea (windpipe) is usually also cut, blood may be inhaled, making asphyxia a secondary factor. If the trachea is partially cut while the carotid arteries and jugular veins are missed, inhalation of blood (asphyxia) may be the actual cause of death, but this is unusual. In one case of this sort, the victim died after about thirty minutes. 30

Very occasionally, the trachea is completely severed without major blood

Suicide and Attempted Suicide • 199 vessel damage. This can cause the lower part of the trachea to fall into the thorax (chest cavity), followed by unsupported soft parts of the neck. This results in mechanical obstruction of the airway and subsequent asphyxia. It's conceivable that an upside-down posture would permit breathing under these circumstances, but this is mere speculation. It's also possible, but rare, that when the external jugular vein is partly cut and open to the air, enough air gets into the damaged blood vessel to cause a fatal air embolism: A large air bubble enters a major vein and is sent to the heart, which isn't designed to pump gases. It's a bit like getting air in your car's brake lines, which is also designed to pump only liquids. Injecting air into a vein has been suggested (and tried) as a suicide method; it's not a good one. Since the output of the heart is around 70 milliliters per beat, you would probably want to inject at least twice that volume of air to make sure your heart developed the cardiac equivalent of vaporlock. This would require something like a bicycle pump and you would be conscious for at least the first three to five minutes.

How LONG DOES IT TAKE TO BLEED TO DEATH FROM

CUTS TO LIMBS?

When death occurs after wrist, ankle, or elbow cuts, it is almost always from loss of blood and shock. How long does this take? Obviously, it varies, depending on which vessels are cut, at what angle they're cut, and where your body is sending blood at the time. A very rough estimate of blood loss would be: 2-3 ml/beat x 70 beats/min = 140-210 ml/min; X 12-18 min = around 2500 ml, which is half your blood supply, and about the limit of what you might survive without prompt medical help. A d d another five to twenty minutes to die, for a total of seventeen to thirty-eight minutes; but this is just a ballpark figure and could easily be off by a factor of two or more. g

If avoiding discomfort is a priority, be aware that severe loss of blood causes a physiological anxiety response.

CUT/STAB WOUNDS TO THE CHEST

W i t h suicidal chest stabs, death is usually due to either (1) injury to a major vein or artery leading to fatal blood loss or (2) injury to the heart itself or to the sac surrounding it, the pericardium. If the heart is sufficiently damaged, it will hemorrhage and be unable to pump blood. But even if the heart itself is untouched, blood may fill the pericardium faster than it can drain out (or a blood clot may block outflow). This will eventually leave the heart with no room to expand, and thus keep it from filling (and thus pumping) properly ("cardiac tamponade"). In one case a forty-four-year-old man stabbed himself six times in the chest with a seven-inch-long kitchen knife. He then washed and returned the knife. After changing his clothes a number of times, he had lunch with his aunt who apparently didn't notice anything unusual. He collapsed about two hours after stabbing himself and died shortly after reaching the hospital. The pericardial cavity was found to have 300 milliliters of partly clotted blood; another 410 milliliters was in the chest cavity. The heart muscle received cuts, but the cause of death was cardiac tamponade. 31

TYPES OF WEAPONS USED

In Sweden, kitchen knives were used in about one-third, razor blades in another third, and other knives in one-fifth of cutting and stabbing suicides. There is similar data from Japan, where the same three categories accounted for 78 percent of cutting and stabbing suicides. The length and shape of the wound track usually give a good, but not infallible, reflection of the weapon used. Obviously a wide blade cannot make a narrow wound track, but a slim blade is certainly capable of expanding a narrow cut into a wider one. Similarly, a four-inch blade cannot make an eightinch-deep cut, but an eight-inch knife can easily make a shallower cut by the simple expedient of not thrusting to the hilt. It is possible for the track to be an inch or more longer than the blade: If the thrust is made with enough force, it will compress the body. This was the situation in a fatal stabbing in the heart with a small pocketknife. In stabbings where the weapon was thrust with great force, there is also usually bruising around the injury site(s), the pattern matching the shape of the weapon's hilt, or sometimes the assailant's fist. 32

Suicide and Attempted Suicide • 201 COMBINATION OF CUT/STAB WITH OTHER METHODS

Cuts and stabs are sometimes combined with other methods. For example, one forty-two-year-old woman was found with her head submerged in the bloody water of her bathtub, with hesitation cuts on her wrists, ankles, and neck and a "star-shaped bullet wound on her forehead." She had also consumed a fatal dose of sleeping pills. (Clearly, she intended to die.) 34

Another woman, a forty-nine-year-old alcoholic, tried to hang herself from the electric cord of an overhead light, using a twisted bedsheet for a ligature. When the noose broke, she stabbed herself in the chest with glass from the broken lamp diffuser; and when that failed to kill her, she grabbed a kitchen knife and fell on it, ramming it deeply—and fatally—into her chest. 3

Others leave more doubt about their intentions. One thirty-two-year-old woman was found dead in a motel room she had checked into twenty-four hours earlier with a male companion. "A blanket was neatly folded under the arm to absorb the expected bleeding, and the bloodstained razor blade was placed on a handkerchief on the dresser." However, there was little blood at the scene, and the autopsy showed that only one medium-sized superficial vein had been severed. She had died of acute alcohol intoxication. 36

How TO Do IT; HOW NOT TO DO IT SUICIDAL GESTURE:

• Avoid alcohol, and drugs that interfere with blood clotting, such as aspirin. • Clean skin on wrist with alcohol swab for one minute (you wouldn't want to die of infection). • Optional: anesthetize skin. The most readily accessible local anesthetic will be a "freeze" spray commonly used for athletic injuries. It works by evaporating so quickly that it chills and numbs the sprayed area. One particular product is Cold Spray. These are short-acting products, but should not be used on skin once it's cut or broken. If you have access to "caine" anesthetics (lidocaine, procaine, cocaine) you may prefer to inject one of these into the target site, since they are more effective and longer-acting. However, you need to know

2 0 2 • Geo Stone what you're doing since these drugs can be dangerous if poked into a vein or artery, or if you're allergic to them. • Sterilize (or buy sealed and certified-sterile) a razor, scalpel, Xacto knife, etc. If it's not already sterile, heat the blade to a dull red color using a propane torch, or gas or electric stove rather than candle or match—the latter two may not be hot enough and/or may leave unsightly deposits on the blade. Let the blade air-cool or set it on a sterile surface. Chemical sterilization is less reliable than heat. If you want to use razor blades, get single-edge; the double edge are both flimsier (they flex at inopportune moments) and much harder to hold and control when slippery with blood. • Have sterile gauze dressing, tourniquet, and tape available. • Cut across (not lengthwise) the large surface vein that goes diagonally across your wrist, or the thumb-side vein that goes along the inside of the wrist (the one that IV lines are often stuck into). You may want to have a tourniquet around your upper arm both to make the vein stand out more and to limit blood loss. Don't go deeper, or closer to bones, and avoid cutting anything that looks or feels like a tendon or like a pulsing blood vessel (artery). • Get help. After all, what's the point if nobody knows? You probably shouldn't walk to the hospital if you don't have to—you could pass out on the way and people might ignore "another drunk" while you bleed to death. Driving yourself is also a bad idea, since an impaired driver puts others at risk. Better to have a friend (make sure they're home first) take you or call for ambulance or rescue squad. Avoid Friday and Saturday nights—they're busy ER times. If you do this carefully, you will (almost) certainly survive with nothing more than a scar or scars on your wrist. However, be prepared for unexpected behavior from family and friends and don't count on much medical sympathy. In addition there is the problem that the safer you make the suicidal gesture, the less "seriously" it may be taken. This should not be the case, since about 10 percent of people who do "safe" suicidal gestures eventually go on to kill themselves. 37

38

Suicide and Attempted Suicide • 203 You may prefer to use an ankle vein in order to avoid wrist scars, and subsequent tedious cocktail-party conversation. SUICIDE

If you really intend to kill yourself by cutting and stabbing, there would seem to be no particular point to sterile technique. But you might as well do it that way on the off chance that you're rescued. It's also a good idea to have tourniquet, tape, gauze, and a telephone next to you just in case you have a belated change of heart. Since you're trying to kill yourself by bleeding to death, your preparations should be directed toward keeping your blood from clotting. To this end you might eat a few (four to eight) aspirin about an hour before the main event. Can't hurt, might help. It also might decrease the pain a bit. WRIST.

An excellent meal, hot bath and a glass or two of good wine—after all, you won't get another chance—should be pleasant and relaxing. The alcohol and hot bath will also have the effect of increasing your near-the-skin blood flow. More importantly, since our blood has a hard time clotting in water, keeping a sliced wrist submerged increases blood loss. Using a properly aimed spray of water from a shower head is even more effective because the motion of the water and mechanical action of the drops further interfere with clot formation. It also improves the visual aesthetics, for whoever finds your body, not to have a tub filled with blood. You may want to rig a "stand-off": something to keep your wrist from falling against your body or the tub and thus slowing blood loss; or use blood vessels in your ankle instead of, or in addition to, your wrist. Now, the best preparation in the world won't do the job if you don't cut yourself adequately. To lose a lot of blood in a hurry you need to either cut a good artery or two or several veins. As discussed in more detail above, you can feel the arteries on the insides of the wrist near the long forearm bones. Cutting them lengthwise is more effective, but either way should work. If the blood spurts out you've hit a gusher of an artery; if it flows, you got a vein. Cutting several times across the underside of the wrist may well get you enough veins and small arteries to do the trick, but if you want to be faster and more certain, go for the radial or ulnar arteries. On the other hand, maybe there's no hurry and you want to savor the

slowly spreading pool of red in the tub. Fine. Just be aware that you will eventually lose consciousness and that a bit later you will have a "window of opportunity" for brain damage from lack of oxygen before you die. That would not be a good time to be rescued. On the third hand, it's entirely possible that you will slide underwater when you become unconscious and thus drown before you can bleed to death. I suppose if you wanted to make this more likely you could use an air pillow to support your head above the water: You hold the air valve shut by hand; when you lose consciousness your hand falls, the valve opens and lets out the air. Or perhaps this is getting too complicated. 39

An alternative method has been suggested. It consists of running an IV line into your favorite elbow vein, using a big-bore needle (say, 16 gauge), taping it into place, and letting it drip away. Call the Red Cross for details, though they may suggest a better use for your blood. I'm not aware of any cases using this technique. It would certainly be slow, and probably subject to clotting, but I don't know this for a fact. The femoral arteries and veins, going through the groin to the legs carry a lot more blood than does the wrist plumbing. Cutting them is thus more quickly fatal. It also allows use of both hands and avoids wrist tendons, but is hard to stanch or tourniquet should you change your mind after the fact. THROAT. If you're going to cut your throat, the three major structures that are commonly injured are the carotid artery, the jugular vein, and the windpipe. These are all accessible from the front of the neck, but the major blood vessels are partly protected by the sterno-mastoid muscles nearby. (Turn your head to the side and feel them.) The large carotid is on the right side under the angle of the jaw (where you can feel your pulse). It's most accessible by cutting in between the trachea and the sterno-mastoid muscle. Completely severing it will cause unconsciousness in a couple of minutes and death in about five. Not pleasant, but fast. Throwing the head back moves the carotids under the sterno-mastoid muscles and may require deeper cuts or limit damage to the trachea or larynx. Cutting the jugular vein on the left side of the neck causes death almost as quickly, but you may remain conscious a minute or two longer, since blood continues to enter the head. Similarly unpleasant. Cutting into the windpipe is not generally life-threatening unless it is either cut all the way through or a lot of blood enters it. In fact there is a sur-

Suicide and Attempted Suicide • 205 gical procedure for cutting a passage into the trachea near the breastbone (tracheotomy) in order to bypass an obstruction to breathing. If you insist on cutting your throat, go for either of the major blood vessels: the carotid (on the right side of the neck) or the jugular (left side of the neck). No extra credit for cutting both. If the trachea is also cut it won't make much difference, but it shouldn't be the target. TRUNK. The only target worth aiming for is the heart: Single-stab injury to other organs is too slowly fatal unless you happen to hit a major blood vessel. The heart is somewhat protected by the cartilage and/or bone structures of the chest and ribs. The ease of getting through varies a lot from one location to the next. To most reliably reach the heart may require either a strong thrust through the chest wall—falling onto a knife will be more than enough—or an upward stab from between a pair of ribs. In either case, it is easier to get through if the wide part of the blade is held horizontally rather than vertically. Death from heart wounds can be fast, slow, or, occasionally, not at all, depending on the nature and extent of the injury. If it occurs, death can take from a couple of minutes to several hours (and, rarely, longer). However, remarkable feats are sometimes seen, despite fatal injury: One man, though shot through the heart, ran sixty to eighty yards and then took part in a fight before collapsing. 40

SUMMARY

The fact that only about 4 to 5 percent of suicidal cutting and stabbing are fatal should not leave you with the impression that they are safe. They are about as safe or as dangerous as you make them. The most quickly fatal suicidal cut is one that severs the carotid artery and/or jugular vein. An untreated stab to the heart is usually lethal but not always as swiftly as one might expect. In addition, many people are unclear about where the heart actually lies; they tend to aim too far to the left and sometimes too high, and may miss altogether, a telling commentary on the sorry state of modern science education. The danger from wrist cutting varies from trivial to deadly, depending on the circumstances, as discussed in detail above. If you're in a hurry, but don't want a gaping gash in your neck, you might want to consider the femoral artery, whose pulse you can feel just below the crease in your groin.

206 • Geo Stone As a suicidal gesture, a single wrist or ankle cut is pretty safe if you avoid tendons and the two major arteries, don't cut deeply, and have a tourniquet in place (you can always hide it when the rescue squad arrives). As methods of suicide, cutting and stabbing have little to recommend them: Compared to lower-trauma asphyxias (see Hanging and Asphyxia chapters) they are, generally, more painful and no faster or more reliable. Their major advantage is that (depending on site and method) you may, after the injury, have some time to change your mind.

A man who is not afraid of the sea will soon be drowned, he said, for he will be going out on a day he shouldn't. But we do be afraid of the sea, and we do only be drowned now and again. — J . M. Synge

N o w would I give a thousand furlongs of sea for an acre of barren ground. —Shakespeare Drowning is an effective and quick means of suicide, usually taking between four and ten minutes. Whether or not it is a low-trauma death, as some have claimed, is in dispute. Drowning is responsible for only 1.3 percent of official suicides in the United States, land of the handgun, but is much more common in many other parts of the world. It is a distinctly poor choice for a suicidal gesture. High High, 67 to 75 percent INJURIES: Moderately likely

PROGNOSIS FOR DROWNING: FACTORS DETERMINING SURVIVAL

The chances of surviving submersion depend mostly on how long someone has been breathing water. Secondary factors are water temperature, age of the victim, and whether the water is salt or fresh. SURVIVAL TIME. Though the medical sources differ, they generally cite somewhere around four to ten minutes as minimum-fatal and maximum-survivable times. Even though the heart may continue to beat weakly for several more minutes, there is little chance of recovery. TEMPERATURE. People can swim much longer in warm than in cold water (see Hypothermia chapter). However, very cold water substantially increases the time during which a drowned person can be successfully revived. This is because quick chilling of the body retards cellular damage and death. This, in turn, is due to the fact that at lower temperatures all chemical processes, including metabolism and decay, are slowed. For example, at 20 degrees C (68 degrees F), metabolic rate, as measured by oxygen consumption, drops to about one-fourth that of normal body temp (37 degrees C, 98.6 F). 1

Recoveries after as long as twenty to thirty minutes in very cold water are not uncommon. The longest documented submersion without brain damage is sixty-six minutes (body core temperature was 66 degrees F [19 degrees C]). However, two-thirds of these recoveries are in children under eight years of age though only about 20 percent (about 865 out of 4,200 in 1988) of accidental drownings are in this age group. The reasons for this high survival rate seem to be: (1) Children cool more rapidly, since they are smaller; (2) they are protected by a phenomenon called the "mammalian diving reflex," which is strongest in kids up to two to three years old. When such a child falls into water, more blood is sent to her brain and heart, the heart slows to just a few beats per minute, and the 2

However, even someone who seems to have been successfully resuscitated may have suffered permanent or even fatal injury: Pneumonia can develop, especially from contaminated water; temporary kidney failure sometimes occurs, caused by the red blood cell destruction following massive absorption of fresh water; heart failure and/or brain damage due to lack of oxygen may be seen. The frequency of brain damage reported in near-drowning cases ranges from 2 percent to over 30 percent. If near-drowning is defined as having impaired consciousness on arriving at the hospital, the latter figure is probably more realistic. Recovery may take weeks or months and may be incomplete. 5

WHAT IS DROWNING?

The short answer is: Drowning consists of filling the lungs with liquid so that oxygen cannot be absorbed. To the extent that this is the direct cause of death, drowning is another form of asphyxia. Further, inhaling water can cause the airway (larynx) to spasm shut or the heart to suddenly stop. In addition, both fresh and saltwater damage the blood, lungs, and heart, though some medical consequences of drowning depend on whether saltwater, fresh water, or some other liquid is inhaled. Here's the long answer: Someone who is conscious can hold his breath until carbon-dioxide buildup in his blood stimulates the brain's respiratory center, which overrides any voluntary breath-holding and forces an inhalation: You cant not breathe. If the mouth and nose are under water at this moment, water is inhaled. This in turn causes reflex coughing, gagging, vomiting—and additional inhalation, often of more water. This cycle continues until consciousness is lost, generally within two to three minutes, due to lack of oxygen. Convulsions and cessation of breathing follow quickly, which is followed more slowly by heart failure. Brain damage, then death, usually occurs within four to ten minutes. b

Foam frequently comes from the mouth and nose of a drowning victim, but sometimes this is not visible until pressure is applied to the chest in a re-

2 1 0 • Geo Stone suscitation attempt. The foam is usually white, but may be bloodstained and may persist for several days (depending on temperature) on a corpse in the water. It is produced by a mixture of air, water, mucous, and other components, whipped into a froth by desperate respiratory activity. It may be more frequent in accidental than in suicidal drowning, if in the latter the person is less likely to struggle, but this is speculation based on the fact that people who are already unconscious when they drown don't produce this foam. 8

9

The presence of foam is normally accepted as proof that drowning was the immediate cause of death. Thus, bloody foam at the mouth and nose of Mary Jo Kopechne led (or allowed) the judge at the Chappaquiddick Island inquiry on her death in 1969 to refuse to order an autopsy, ruling that it was sufficient evidence that death was due to drowning. However, fluid in the lungs (pulmonary edema) from illness or injury can also cause similar foaming. The more graphic description of drowning that follows came from observations on dogs that were tied up and held under water until they were dead. The first stage was described as "surprise" and lasted a few seconds. This was followed by violent agitation in which the dog tried to escape its bonds and reach the surface while holding its breath. This lasted about a minute. The third stage, also about one minute long, consisted of deep inspirations of water and expiration of white foam. Mouth and eyes were open, and body movements decreased. In the fourth stage, breathing motions stopped, pupils were dilated, and corneal reflexes disappeared; another minute. In the last stage, lasting thirty seconds, there were three or four respiratory gasps and a few spasms around the lips and jaws. c

10

11

These observations were later confirmed when a man who had drowned his pregnant wife gave a detailed description of her death in very similar terms. In general, and not surprisingly, near-drowning victims show less in the way of severe biochemical imbalances than do drowned bodies. For example, a study of eighty-three near-drowning cases showed none with lifethreatening salt imbalances. Curiously, 10 to 30 percent of drowning victims' lungs are found to be fairly dry on autopsy. There are physiological processes that could account for this phenomenon: Since the heart can continue beating for a short time after respiratory reflexes have ended, water absorbed from the lungs into the 12

13

14

Suicide and Attempted Suicide • 2 1 1 bloodstream can be distributed to other parts of the body. Meanwhile, little additional water will reach the lungs; hence a drowned body with dry lungs. 15

An alternative explanation is that these people died suddenly from a process called "vagal inhibition." The vagus nerve, which normally slows the heart in response to an increase in blood pressure, can also be triggered by inhaled water or by pressure on the side of the neck (see the Hanging chapter). It can cause the heart to stop from relatively small amounts of inhaled water, thus resulting in sudden death with few signs of drowning. In one case, A boy, aged two and a half years fell head first into a drum which contained some chalky, sooty water; the water level was only six inches above the bottom of the drum.The child was removed at once, but prompt resuscitation was of no avail; the child was dead. It was readily possible to trace the internal distribution of the water by its sooty content. Soot was present in the nasal cavities; there was a little in the larynx and traces of soot adhered to the vocal cords and the wall of the trachea, but there was none in the lungs. The child had swallowed about an ounce of the water but there was no soot in his mouth.The level of water in the drum was too low for any of it to have entered except by the nose. 16

A third possibility is that when water starts to be inhaled, it causes a powerful reflex closing of the epiglottis —one of the protective actions of the previously mentioned mammalian diving reflex—but this cuts off air as well as water and people start to asphyxiate. When this occurs, the face looks like that of a typical asphyxia victim: bluish color with pinpoint hemorrhages often visible on the eyelids and face. After two or three minutes, carbondioxide buildup in the blood overcomes this protective reflex; of course, if this "terminal gasp" occurs while the face is submerged, the lungs fill with water anyhow. While there is evidence for each of these mechanisms, there seems to be no general agreement among the medical experts as to their relative importance or frequency 17

212 • G e o Stone

The notion that a drowning person rises and sinks three times before finally going down has no basis in fact. However, it is true that: • Unless someone is very fat, his dead body will sink in fresh water; most will also sink in ocean water, which is about 2 percent denser at a given temperature; • Since your head is your densest part, you'll end up head-down at the bottom; • Drowned bodies sink and then rise to the surface some time later due to gases formed during putrefaction How much later depends mostly on water temperature. In New York, for example, about half the annual floaters come to the surface in A p r i l and May: "If somebody jumps in the water in the summer, they'll be up the next day, but if somebody jumps in November, they won't come up until the spring. The deeper the water, the longer they take to come up" (Sgt. Jim Cowan, New York City Police harbor diver). A secondary factor is that snow melt and spring rains can churn up the bottom and release bodies that are snagged on submerged tree limbs and other debris at the bottom of rivers. 18

19

FRESH VERSUS SALTWATER DROWNING

Surprisingly, the standard forensic texts differ considerably in their assessment of the relative dangers of inhaling fresh versus saltwater. For example, one says that drowning in saltwater is twice as lethal as in fresh (but doesn't define "twice as lethal"). Another says that saltwater drowning is "likely to be more amenable to resuscitation than drowning in fresh water." A third claims that drowning takes four minutes in fresh water and eight in saltwater. 20

21

22

While these experts reach different conclusions, there is general agreement on some fundamentals: PHYSIOLOGY. Lack of oxygen (asphyxia) is the primary cause of death in drowning. However, in people who are rescued, the effects of salt- and fresh water on the heart and lungs differ significantly, changing both the optimal treatment and the likelihood of survival.

Suicide and Attempted Suicide • 213 What accounts for these differences between the effects of salt- and fresh water? D i d you ever do a school biology lab exercise in which you looked through a microscope at red blood cells that had been put into fresh and saltwater? If so, you may remember that the cells in fresh water expand until they break up; those in saltwater shrink and wrinkle. The reason is that these cells are semipermeable; that is they let water through the cell wall, but not (much) salt. This means that a bit more water is constantly entering a cell (0.9 % salt) which is in contact with fresh water than is leaving it. As a result, the cell expands and finally ruptures. In saltwater the principle is the same, but the net direction of water flow to/from the cell is reversed because most ocean water is more than 3 percent salt and thus only around 97 percent water. That is, more water will leave than enter a cell, which will shrivel. Not surprisingly, this is less damaging to a cell than is bursting. Lung cells are also semipermeable, but instead of bursting from absorbing too much fresh water, they're able to channel most of the excess into the bloodstream, with which they're in intimate contact. This happens very quickly: W i t h i n three minutes or so, half the liquid in the bloodstream may be from inhaled water. While temporarily protecting lung tissue, this has some undesirable effects: 23

• It decreases the concentration of sodium and calcium in blood serum which interferes with nerve and muscle function; • The serum dilution causes red blood cells to expand and break up and increases the volume (while decreasing the concentration) of blood. This increased volume makes the heart pump harder, which forces fluid into the lungs—which, as you may imagine, hardly need more liquid. Thus even if someone is rescued and has her lungs drained, pulmonary function may be impaired due to the additional fluid pushed into the lungs from the diluted blood. Meanwhile, the heart isn't getting enough oxygen, primarily because the water-filled lungs can't provide it, secondarily because the concentration of functioning red cells is low, while, at the same time, the heart needs more

2 1 4 • Geo Stone oxygen since it's working harder. Under this combination of circumstances (aptly described as "a serious biochemical insult,") the heartbeat quickly becomes irregular, blood pressure drops to dangerously low levels, and ventricular fibrillation (unsynchronized contraction of heart muscle) causes death within three to five minutes. The experts disagree about the relative importance and frequency of these mechanisms. 24

25

In fresh water drowning, the breakup of large numbers of red blood cells decreases the blood's ability to transport oxygen and also releases the cells' contents into the circulation. The most immediately significant component is potassium ions, which can cause the heart to fibrillate and fail. This is offset, to some degree, by the initial absorption of water, which dilutes the released potassium. d

As an aside, normal blood volume is around five liters. In fresh water drowning, this can be diluted by several liters of water, so measurement of alcohol or other drug levels must be adjusted to take this into account. After resuscitation from saltwater drowning, pulmonary edema also quickly occurs, but by an entirely different mechanism—the salt remaining in the lungs "pulls" (by osmosis) water from the lung tissue into the air spaces, thus filling the lungs and preventing them from picking up oxygen. The net water loss from the lung cells in turn draws water out of the bloodstream and into the lung cells. However, the amount of blood volume lost is less than the amount absorbed in fresh water drowning. Since the resulting blood electrolyte imbalance is also less, the often-lethal heart arrhythmias seen in fresh water drowning are infrequent in saltwater drowning. Heart failure, from the combination of lack of oxygen and the increased viscosity of water-depleted blood, takes longer to be fatal and is more likely to permit effective medical intervention. 26

27

Thus saltwater drowning victims don't die as quickly as those in fresh water, and there is a better chance of reviving someone drowned in saltwater. CHLORINATED WATER. Pulmonary edema also occurs after drowning in chlorinated swimming pools, in part because chlorine irritates lung tissue. Indeed, chlorine was the first poison gas to be used in warfare (1915, Ypres). 28

Suicide and Attempted Suicide • 215 TREATMENT OF DROWNING The first and most important thing to do is to perform immediate artificial respiration; even a few minutes' delay will be fatal. Mouth-to-mouth resuscitation is the most effective low-tech method; attention to other injuries must wait. If medical care is available, defibrillation and blood transfusion may help in fresh water drowning; repeated lung suction may be needed for saltwater cases; adjustment of blood electrolytes (salts: mostly sodium, calcium, and potassium) may be useful in both fresh- and saltwater victims. 29

How DANGEROUS ARE SUICIDAL DROWNING ATTEMPTS? Tables 16.1 through 16.4 show that drowning is a quite lethal means of suicide: The fatality rate was 67 percent and 75 percent in two large studies. The lack of minor and moderate injury results is further evidence that it's not a good choice for a suicidal gesture.

DEMOGRAPHICS: W H O COMMITS SUICIDE BY DROWNING? In 1994 there were 3,942 (3,179 male and 763 female) drownings in the United States listed as "accidental" and 383 (254 male; 129 female) attributed to suicide. This is 1.2 percent of the 31,142 official suicides in that year and is similar to the worldwide frequency of suicidal drowning: 1 to 2 percent. 30

However, local rates may vary substantially. For example, 22 of 207 (8.5 percent) suicides in the Province of Newfoundland died by drowning, as did 7.3 percent of Japanese suicides, 15 percent of Norwegian, and 4.5 percent of suicides (70 of 1,569) in Dade County, (Miami) Florida, which is about three-and-a-half times higher than the U.S. national rate. These higher percentages are likely due to lengthy ocean coastlines and/or a long nautical tradition. The suicide rate from drowning decreased by almost half between 1979 and 1994; from 0.25 in 100,000 per year to 0.14. Drowning is also the only method in which black males have higher rates than white males: 0.39 versus 0.21 (1979 to 1994). Some more-detailed information is available from Dade County, Florida. Sixty of 70 suicidal drownings (85.7 percent) there died of simple drowning; three (4.3%) had "contributory drug overdose," which does not include alcohol. Three had contributory self-inflicted injuries (for example, cutting one's wrist or throat just to "make sure"; four (5.6%) had contributory illness/disease (serious physical illness that may have been the impetus for suicide). 31

2 1 8 • Geo Stone It is, of course, simplistic to believe that most suicides have a single cause, but the urge to look for simple answers to complex problems is widespread. Most Florida drownings occurred in lakes, rivers, canals, bays, the A t lantic, or the G u l f of Mexico, but a dozen (17 percent) occurred in swimming pools and five (7 percent) in bathtubs. Twenty (28.6 percent) left suicide notes and eighteen (25.7 percent) gave a verbal equivalent; thirtytwo (45.7 percent) did neither. A British study of 536 "probable suicides" found that drowning was the single most underreported method: Only 24 percent had been officially designated as suicides. Reasons for this include: (1) Unless there is unambiguous evidence, a verdict of suicide will rarely be rendered; (2) many drowning victims, both accidental and suicidal, are drunk ("Bacchus hath drowned more men than Neptune" ), which makes it easy to attribute the death to alcoholic mishap; (3) where the victim was known to have a medical condition such as epilepsy or heart disease that could have caused unconsciousness, the drowning will almost always be declared "accidental" absent strong evidence, such as a suicide note, to the contrary. 35

36

ACCIDENTAL DROWNING

In accidental drowning a large majority of every age group, even infants, was male. This male to female ratio has been attributed to greater mobility, energy, and exploratory behavior in infant males, and increased risk-taking and generally stupid behavior later. It should be noted that the five-gallon buckets widely used for paint, premixed drywall compound, and many other things, are extremely hazardous to curious toddlers, who tend to fall in head-first and are then unable to get out. About fifty kids annually drown in them in the United States. 37

g38

An aside on some accidental drowning: It's not generally known that every year there are a number of unexplained drownings, mostly of young males between fifteen and twenty-four years old engaged in underwater endurance contests, along the line of seeing who can swim further while submerged. Since most swimmers are aware that one can hold one's breath longer after hyperventilating, the evidence associates hyperventilation followed by exercise, with unconsciousness, leading to drowning, even in fit, competitive swimmers. 39

Suicide and Attempted Suicide • 219 A possible explanation is that hyperventilation depletes blood of dioxide. Since the urge to breathe is due to CO buildup (not lack of oxygen), it may be, when exercising and holding one's breath, that one runs out of oxygen and becomes unconscious before the breathing reflex kicks in. Another expert thinks that these deaths are due to reflex inhalation upon hitting cold water. The same researcher has found that sudden immersion in cold water causes an increase in blood pressure that can trigger heart failure. 2

WHAT DO DROWNING PEOPLE THINK ABOUT?

In popular lore, drowning persons (besides invariably going down three times) spend their last moments reviewing their lives. Sometimes this appears to be what happens. As a youth, a British sailor named Beaufort (not the same Beaufort for whom the wind scale is named) fell overboard into the sea. Years later he wrote about the experience to an acquaintance. After swimming for a while he lost all hope, he said, and, "From that moment all exertion ceased, a calm feeling of the most perfect tranquillity superseded the previous tumultuous sensations. It might be called apathy, certainly not resignation, for drowning no longer appeared to be an evil. I no longer thought of being rescued, nor was I in any bodily pain." He compared his feeling with the state just before sleep: senses dim but mind active. He thought about his family, his last voyage, and adventures he had experienced. He was rescued and went on to an eminent naval career, ending as an admiral. Another man related similar experiences: While half-conscious and lying at the bottom of a river, he felt no pain, but he had colored vision and ringing in his ears. He visualized his friends and relatives attending his funeral, even dirt dropping on his coffin. He lost consciousness and woke up on the riverbank, "being subjected to the disagreeable process of restoration of life." 42

43

Not everyone's near-drowning experience is so tranquil. One woman described it thus: "I sank again and gasped involuntarily. Then all other senses were overpowered by the agonising scorching pain which followed the rush of saltwater into my lungs. From that moment I was conscious only of the burning suffocation, and the intense desire that the others might know what

220 • G e o Stone

44

had become of me. Except for that one thought my brain was dulled." She, too, heard roaring in her ears and saw through a colored (red) mist. She was unconscious when rescued.

WAS IT SUICIDE, HOMICIDE, OR ACCIDENT?

This is often a difficult call since there are no reliable physical signs in or on the body that, alone, would allow a verdict. This differs from, say, knife wounds, which are generally quite informative. In addition, the body may not be found before decay and scavengers make it difficult enough to figure out who, let alone why. There is a further diagnostic problem: D i d the person actually die from drowning or from some other cause? As mentioned previously, sometimes the lungs are dry in known drownings, and lungs can become waterlogged after death, at least in turbulent water. In addition, even the presence of sand and seaweed in the lungs and stomach are not proof of drowning: Both were found in the body of a young woman discovered on a deserted beach with a contact bullet wound in the center of her forehead. The visible characteristics of drowned bodies (wrinkled skin, goosebumps, diatoms in the lungs, retracted penis and scrotum) are also found in other submerged bodies, and the levels of blood electrolytes are affected by postmortem biochemical changes. Because of these uncertainties, the most reliable evidence for drowning is still the presence of white foam around the mouth and nose of the victim. h45

SUICIDE

Suicidal drowning is not very common in the United States, but is certainly underreported. Drowning is a convenient way for a suicide to look like an accident: One simply doesn't come back from a swim, or perhaps one drives the car off the road into water. Skid marks add verisimilitude, but even without them it would be difficult to prove suicidal intent without other evidence. Most drownings in bathtubs are suicides; in a series of forty-two cases only nine were accidental or due to illness; thirty were suicides (twentyone female, nine male). A majority of people who commit suicide by drown46

Suicide and Attempted Suicide • 221 ing are partly or fully clothed; whether they are frequently under the influence of alcohol or other drugs is in dispute Obviously if someone is unconscious or unable to move, the depth of the water they fall into makes little difference. For others, while deep water provides more certainty, even shallow water may be fatal. For example, a fiftyyear-old woman committed suicide by sticking her face into a bowl of water only six inches deep. She was found dead in bed with the bowl still in her hands. In another case a baby was drowned by his father, who held the child's face under a running water spigot. Death was due to absorption of water from the lungs into the circulatory system. 47

48

49

Sometimes more than one method is used: A sixty-five-year-old woman with multiple blunt injuries and her throat cut was found in a shallow river Bloodstains were found on a small bridge crossing the river and on the ground of the adjacent terrain. Following the stains, the police found a large pool of blood at a place 50 meters [55 yards] from the bridge.The police wanted to know if the woman could have cut her throat herself at this place and walked to and jumped into the river afterward.The autopsy showed that the cause of death was drowning and that the blunt injuries in all probability stemmed from collision with stones on the river bottom.The cut throat was the result of two superficial cuts, and only the superficial jugular vein was severed. It was concluded that she could have walked the distance in question after her throat was cut. 50

HOMICIDE

Drowning a resisting, healthy adult in shallow water is difficult, and to do so without causing suspicious-looking injuries is even harder. One man, George Joseph Smith, did manage to drown three wives (one at a time) around 1910 by lifting their feet while they were bathing, thus minimizing their visible injuries. These were the notorious Brides of the Bath murders. Despite his efforts to disguise the crimes, Smith was caught and executed. Naturally, it's easier to drown someone if they're incapacitated first. In one case, a nurse injected his pregnant wife with insulin; when she lost con51

sciousness, he put her into the bathtub and drowned her. She had believed that the injection was to induce an abortion.

SUMMARY

This is not a complicated means of suicide. Pretty much all that's needed is some water and a few minutes without interruption. Reports from neardrownings are contradictory concerning pain. To minimize it, one may take enough alcohol or sedatives to become unconscious while swimming or bathing. To decrease chances of unwanted resuscitation, avoid drowning in freezing water. Drowning is a fairly quick and frequently lethal—two-thirds to threequarters of such attempts are fatal—means of suicide, usually taking between four and ten minutes, but there is some danger of brain damage if you're rescued after being unconscious. Drowning is a very poor choice for a suicidal gesture.

20 DRUGS, CHEMICALS, AND POISONS

All things are poisons, for there is nothing without poisonous qualities. It is only the dose which makes a thing poison. —Paracelsus Theophrastus From my own attempt experience with sleeping pills, I can tell you to avoid any that have aspirin/ibuprofen/acetaminophen in them—as tempting as it may be to go with a label that says "Takes away the pain." (Which is I presume what you're trying to do, take away the pain.) Painkillers in high doses can cause liver damage, and this is anything but a painless experience ... Be warned of one other thing, though: All those people you see on TV and in the movies that use sleeping pills to off themselves, they seem to take the pills and then fall asleep right away. It doesn't work that way. More sleeping pills will not make you fall asleep faster—just deeper. You will have as much as a half an hour; once those pills are in your stomach, to contemplate exactly what it is you've just done. "Impulsivity and lack of knowledge about the dangers of drugs can sometimes result in an unintended fatal outcome." Or an unintended survival. Or permanent injury. A drug overdose can be a fairly safe suicidal gesture, if you pick the right drug, right dose, and right circumstances—and there are 1

Suicide and Attempted Suicide • 225 no unexpected problems. Otherwise you can be dead within minutes or permanently injured. The focus of this chapter is to provide information on the toxicity of some commonly used drugs and household chemicals. It is meant to help those who want to survive a suicidal gesture pick a relatively safe drug and dose; those who intend to die pick a drug with a more or less acceptable combination of lethality, speed, and unpleasantness. There is also material on: (a) practical issues, such as acquiring and administering drugs; (b) demographics—who tends to take overdoses; (c) the effects of drug overdoses; (d) what drugs are most often used in suicide attempts.

PROS AND CONS OF DRUGS AS A MEANS OF SUICIDE OR SUICIDAL GESTURE

Pros: • Drugs often readily available. • Can choose high or low toxicity drugs. • Doesn't require physical strength or dexterity. • Easy to do. Cons: • Most drugs take hours to be lethal (a possible advantage if you change your mind) but the toxicity of some is not reversible (a distinct disadvantage if you change your mind). • Most people have no clear idea about the lethal or safe dose of the drug(s) they take. • There are no "guaranteed safe" or "guaranteed lethal" doses, for reasons discussed in detail later. • Many of the drugs/poisons people use are painful and lethal and some may cause (if survived) permanent damage. • Easy to act on impulse.

DEFINITIONS

I use the term "drugs" to mean substances that are generally or commonly used as medicines. Examples are: aspirin (acetylsalicylic acid), propoxyphene

226 • G e o

Stone

(Darvon), and meperidine (Demerol). Generic names (for example, aspirin) will generally be used in preference to trade names (for example, Anacin) because there are usually many trade names for a single drug. However, if a single trade name has widespread recognition (for example, Darvon), this name may be used. Chemical names (for example, sodium hydroxide) and any equivalent common name (for example, lye) will be used for nonmedical chemicals. "Chemicals" refers to substances whose use, packaging, and distribution are primarily nonmedical. Examples are: ethylene glycol (the most common type of car antifreeze), methanol (wood alcohol; solvent and windshield washer liquid), and lye (usually sodium hydroxide; one type of caustic drain cleaner). Drugs are, of course, chemicals, but a medical/nonmedical-use distinction is useful. A poison is just a chemical or drug in a toxic dose. DEMOGRAPHICS: WHO, WHERE, AND HOW MANY

We'll start with a brief look at the overall suicide rate, and the suicide rate from the use of solid and liquid poisons in selected countries, as reported to the World Health Organization ( W H O ) . Be aware that these numbers must be taken with several grains of salt (sodium chloride), because these data are notoriously unreliable due to the social (and sometimes legal) stigma attached to suicide in many societies. For example, in one British examination of 536 "probable suicides," only 60 percent had been given that verdict and thus appeared in official suicide statistics. Of those who had taken poison, the figure was 40 percent. Since women use more underreported methods than men do, their suicide rate is also more underreported (in this study, 51.7 percent of female suicides were reported, compared to 64.5 percent of males'.) In the United States (1994 data), suicide by use of solid and liquid poisons (including drugs) occurred at a rate of 1.16 in 100,000 population per year as part of an overall rate of 11.95 in 100,000 per year. These poisons accounted for about 10 percent of the total number of U.S. suicides, but more than 20 percent elsewhere in the world. Of ten European countries, plus Australia, Canada, Japan, New Zealand, Venezuela, and the United States: 2

Suicide and Attempted Suicide • 227 • the average (unweighted mean) suicidal poisoning rate, by solid or liquid poisons, was 3.0 in 100,000; • the average overall rate was 14.9 in 100,000; • the highest value for solid/liquid poisoning was 9.9 in 100,000, in Denmark (overall rate of 31.6 in 100,000); • the lowest was 0.7 in 100,000, in Italy (overall rate of 7.4 in 100,000); • the highest percentage of suicides by solid or liquid poisons was in England and Wales (37 percent) (overall rate of 8.7 in 100,000); • the lowest was in Japan (6 percent) (overall rate of 17.6 in 100,000). For the most part, suicide rates in these countries increased from 1960-64 to 1980 and decreased slightly by 1988-91, while there was a slight increase in the use of poisons from 1960-64 to 1980. These solid and liquid poisons do not include gaseous poisons (generally carbon monoxide); these gases cause about another 1.1 deaths per 100,000 population per year in the United States. Suicidal poisoning in the United States decreased by one-third, from 17 to 10.3 percent of suicides from 1970 to 1994, while the total suicide rate increased from 11.8 to 12.0 per 100,000, the difference being made up primarily by an increase in gunshot suicides. Historically, these numbers vary considerably both between countries and over time. Furthermore, when particular methods of suicide are minimized (for example, by banning some drug or removing carbon monoxide from household gas), other methods tend to increase. For example, when prescribing barbiturates was restricted (in 1979) in New Zealand, barbiturate overdose deaths dropped by two-thirds, but deaths due to tricyclic antidepressants increased sixfold. Even without significant prescribing restrictions, the same phenomenon occurs as drugs go in and out of style: Barbiturate suicides decreased 80 percent while antidepressant suicides increased fivefold in the United States between 1968 and 1979. 3

M e n kill themselves around four times as often as do women (about 25,000 male [80 percent] and 6,000 [20 percent] female) by all suicide methods combined. Using drugs/chemicals/gases, 3,208 men (about 13 percent of male suicides) and 2,065 women (about 35 percent of female suicides) killed themselves in 1994, a ratio of roughly three to two. However, women make twice as many pharmacological suicide attempts (116,000 versus 57,000 in 1991) that are treated in emergency rooms. 6

We can see that women tend to use medical drugs; men are more likely to go with gases (generally carbon monoxide) and nonmedical chemicals. But even in these latter categories, the proportion of men is less than with all

methods combined, because 60 percent of American males' suicides are committed with guns. While, overall, blacks commit suicide in numbers roughly half those of whites, their suicide rate by drugs, chemicals, and gases is around 0.77 in 100,000 compared to the white rate of 2.2 in 100,000, or about one-third the white rate. Curiously, the age group with the highest suicide rate for men, eightyfive and older, has one of the lowest rate for adult women. There is a second peak for men, ages thirty-five to forty-four; for women, the highest rate is between forty-five and fifty-four years. As with other methods, older people who attempt suicide by drug/chemical overdose achieve more lethal results: while only 40 percent of overdose suicide attempts were by people over thirty years old 71 percent of poisoning deaths were in this age group. 7

How LETHAL ARE SUICIDAL DRUG OVERDOSES?

This simple question doesn't have a simple answer. Estimates of fatality rates range from around 1.2 to 11.4 percent, if we consider all the people who die or are hospitalized after taking drugs with the intention of suicide, self harm, or as a cry for help. The fatality rate from suicidal use of nonmedical poisons is about two times, and from carbon monoxide five times, the medical drug rate. For the United States, a plausible fatality rate estimate—there are no comprehensive national data—might be 1.8 percent for intentional overdoses. The basis for this figure are the N I D A (National Institute on Drug Abuse) 1991 reports: There were around 400,000 (extrapolated) "drug abuse episodes" seen in hospitals in 1990. Suicide was cited as the motive in 43.8 percent of these, or for around 175,000 people. About 0.3 percent (some 525) died. Since there were 3,143 drug overdose deaths in 1990, presumably the remainder, 2,618 (1.5 percent of suicidally intended overdoses), died before reaching hospital. This is consistent with evidence that around 80 percent of overdose deaths are dead at the scene or dead on arrival and with hospital data from around the world that generally report fatality rates between 0.6 and 6 percent for overdoses. b

Suicide and Attempted Suicide • 231 However, these numbers don't include people who weren't hospitalized or whose overdoses were not reported. In addition, these data combine people intending to kill themselves with those wanting to survive. Thus they overestimate the danger of drugs/poisons as a suicidal gesture—for those who know what they're doing—and underestimate the likelihood of death for those really trying to kill themselves. Drugs are used by both groups because, like wrist cuts, but unlike many other methods of self-harm (for example, hanging or drowning), one can roughly estimate the degree of injury from a given drug and dose. However, the results of drug overdoses are less predictable than those from blade injuries. Not surprisingly, overdoses with suicidal intent are more dangerous than accidental poisonings. While only about 7 percent of the incidents reported to the American Association of Poison Control Centers ( A A P C C ) involve suicide attempts, at least 53 percent of the deaths were from suicide (63 percent if the "reason unknown" group is dropped or divided proportionately). In terms of percentage of fatalities from overdoses, death occurred in: 11

c

0.310 percent of suicidal overdoses 0.091 percent of "therapeutic misuse" 0.434 percent of "psychotropic misuse" 0.007 percent of accidental poisonings 0.057 percent of adverse reactions The actual percentage of deaths is certainly higher, since the A A P C C data would not normally include those dead at the scene or dead on arrival, which account for around 80 percent of suicidal poisoning deaths. So, multiplying the suicide figure in the above table by five would probably yield a reasonable estimate of the real fatality rate: about 1.5 percent. The A A P C C numbers differ from data in a frequently cited comparativemethod report by J. J. Card (Tables 16.1 through 16.3). Of 1,476 suicidal drug overdoses there were 168 (11.4 percent) deaths. Card also found that 22 of 95 (23.2 percent) people who took nonmedical chemicals died, as did 117 of 150 (78 percent) who used carbon monoxide. W h y such a large difference between these two inquiries? Fatality rates have decreased since the date of Card's study (1974) because of some i m provements in medical care, but mostly as a result of (1) the general re12

232 • Geo Stone placement of barbiturates by less toxic sedatives; and (2) the decreased amount of carbon monoxide in newer cars' exhaust, due to more stringent air pollution standards. In addition, the real fatality rate is lower than shown here, because minor injuries tend to be underreported. This is true for all methods, but is proportionately more frequent for the less lethal ones: There are more unreported overdoses than unreported gunshot injuries. WHAT IS THE RELATIONSHIP BETWEEN SERIOUSNESS OF INTENT AND THE LETHALITY OF DRUG USED?

The ingestion of 100 5-mg [milligram] diazepam [Valium] tablets is probably more serious [an intention of suicide] in a pharmacologically naive person than in a pharmacologist. Conversely, ingestion of a bottle of acetaminophen [Tylenol, paracetamol] with bourbon may well be a serious attempt in a pharmacologically sophisticated person, but may be intended as a manipulation in a naive attempter (Miller/Micromedex). Do people who take drug overdoses know what they're doing? Often not: There are an astonishing number of suicide attempts, using potentially lethal doses of poison, carried out by people who did not want or intend to die. In a study of 100 consecutive overdose survivors from Belfast, 30 percent of these people said they would not have taken the drug had they known it might kill or otherwise harm them; 52 percent said they would have; 19 percent didn't know; 49 percent took someone else's drugs. Of course, we have no way of telling how many people who die fall into each of these categories. In another study, of adolescent drug-suicide attempters, out of fifty teenagers (forty-five female, five male), half reported thinking seriously of suicide for less than fifteen minutes; eight for between fifteen minutes and one hour; only four thought about it for more than twenty-four hours before making their attempt! In four of these cases (8 percent) physicians thought the drug/dose had a greater than 50 percent chance of being lethal if untreated; only one of these four said that she wanted to die, and in none of these did psychiatric assessors think there had been serious suicidal intent. Similarly, in a larger study, two13

14

d

15

Suicide and Attempted Suicide • 233 16

thirds of 522 fatal self-poisonings in Scotland were described as "impulsive." In a survey of adolescents' knowledge of acetaminophen toxicity, it was found that 40.5 percent underestimated the lethality of this drug and 17 percent thought that one could not ingest enough to cause death. This is a drug that, some years, is the number-one suicidal poison, and is generally among the top three. 17

6

There are around 49,000 annual emergency room visits due to overdoses among twelve- to seventeen-year-olds; 68.2 percent (34,000) are suicide attempts/gestures. Extrapolating the British numbers to the U.S. data, if 8 percent of these 34,000 people took a dose/drug that was more than likely lethal if not found and treated, we have 2,700 potentially dead teenagers. Fortunately, most of them don't die, but their survival depends on timely intervention; if such help is delayed or absent, an unintended death may well result. The number of these is not known. Impulsiveness and ignorance are a lethal combination. Looked at as a practical matter, unless you know what you're doing, drugs, alone, are usually a poor choice for those intending suicide: Most drugs take hours—sometimes days with medical intervention—rather than minutes to be fatal; the effects are often unpredictable and tend to be more traumatic than generally appreciated; too often they result in permanent injury in survivors; and the death rate is low. f

WHAT ARE THE SHORT-TERM MEDICAL CONSEQUENCES OF DRUG/POISON OVERDOSE? 18

It's a common misconception that all poisons have antidotes. In fact, antidotes exist for only about 10 percent of poisons. Most treatment consists of removing as much toxin as possible and trying to keep the person alive long enough for the body to repair itself. What are the effects of drug/chemical toxic overdoses? Not surprisingly, it depends on drug, dose, and individual sensitivity. Unlike in the movies, few drugs cause one to go peacefully to sleep, never to wake again. More often, they generate some combination of pain, vomiting, fever, convulsions, respiratory depression, organ failure, heart arrhythmias, and other serious unpleasantries. 19

234 • Geo Stone Let's now look at the overdose experience of one hospital, to see what drugs were used and the medical consequences and complications of the overdoses. In a review of 419 consecutive acute hospital admissions for drug/chemical overdose, 71 (17 percent) needed intensive care unit (ICU) treatment; 45 in 71 (64 percent) of these more seriously poisoned people were female; 90 percent of them (64 in 71) were suicidal; 8.4 percent (6 in 71) were drug addicts with accidental overdose; one was an accidental poisoning. Multiple drugs were found in 55 percent. There were two deaths in the I C U group (2.8 percent). 20

The most common problem was respiratory depression. This required mechanically assisted breathing, or intubation (an oxygen tube run into the trachea), which is not a great deal of fun. Subsequently there are a lot of lower respiratory tract infections in these people, probably related to inadequate or absent cough and gag reflexes, which may have allowed vomit to enter the lungs. Serious cases show abscesses and necrotizing (tissue-destroying) pneumonia, which is as unpleasant as it sounds. Next in frequency was fever. Usually occurring on the second day, these often are not garden-variety fevers, but high-temperature ones, 105 degrees F (40.5 degrees C) or above, with the potential for causing seizures, brain damage, and death. Since most of the drugs taken suppress cough reflexes, aspiration pneumonia is a frequent complication; either through inhalation of vomit by unconscious person, or through medical procedures intended to remove the drug. This may also lead to bacterial pneumonia. Thus we see that only a small percentage of those who were alive when they got to the I C U died, but that many of the survivors had serious i n juries. LONG-TERM MEDICAL CONSEQUENCES

Some drugs damage specific organs. For example, acetaminophen is mainly toxic to the liver; the herbicide paraquat targets the lungs. More often, overdoses cause general respiratory and/or cardiac depression. The resulting lack of oxygen, in turn, causes acid/base imbalance and further heart damage, because heart muscle tends to become arrhythmic (it beats irregularly and thus does not pump blood) under these conditions. In

Suicide and Attempted Suicide • 235 turn, lack of oxygen can cause permanent brain damage and multiple organ failure.

How FREQUENT ARE SEVERE EFFECTS AFTER "INTENTIONAL" DRUG/POISON OVERDOSES? Of people in the United States who were alive when they reached the hospital (and for whom we have data), 27.4 percent suffered no i l l effects, 55.6 percent had minor effects, 13.2 percent moderate effects, 3.3 percent major effect, 0.45 percent died. Of those with major effects, about 2 percent had permanent injury. 21

22

The following table (20.2) shows the distribution in severity of effects of "intentional" (suicidal, therapeutic, and recreational) overdoses in the United States in 1991 and 1992. Table 20.2 Results of Intentional Drug/Poison Exposure: AAPCC Data

We can see that there are seven or eight people in the "major effect" category for every death. H o w many of these result in permanent injury is unknown. This is substantially different from the older data in Card (see Table 16.3), which shows 1.4 to 2.0 "major effect" cases per death. I don't know why; per-

236 • Geo Stone haps because fewer people are dying, more survive to be in the major effect category Since the A A P C C injury data lump together suicidal and other intentional drug uses, it is less helpful for our purposes; however, from the next table, we can get data that, combined with the above, show that 67.4 percent of the reported cases intended suicide (1991 and 1992 combined), while 71.9 percent of the fatalities (table above) were due to suicide. This suggests that suicide attempters had similar consequences as those who otherwise intentionally overdosed. Table 20.3 Reason for Intentional Exposure

What else can we learn from these data? If we look at the number of deaths as a percentage of the "moderate," "major," and "death" categories— the ones most likely to be admitted to a hospital—we find that the death rate was 2.6 percent, which is within the suicidal-poisoning death rate of 0.6 to 6 percent generally reported from hospital admissions. 3

WHICH DRUGS ARE USED IN SUICIDES AND SUICIDE ATTEMPTS?

The answer depends on both when and where (and who) you ask. Fashions in poisons change: In one hospital in Sweden, barbiturates (for example, Seconal) caused 60 percent of fatal adult poisonings in 1962; by 1976 tricyclic antidepressants (TCAs) (for example, Elavil, Tofranil) were the largest group, despite the fact that the death rate for T C A overdoses fell from 15 to 1.7 percent between early 1960s and 1977. In Switzerland (1983) benzodiazepines (for example, Valium) were the drugs of choice. 24

The Brits seem to prefer ending it all with acetaminophen. In Australia, for a while chloral hydrate was the most-used single drug. In Singapore, Thailand, and Sri Lanka agricultural chemicals are popular. In Sri Lanka more than half of all suicides use agricultural chemicals. "Almost every rural grocery store has shelves full of many brands of pesticides in bottles of various sizes. Over one hundred chemicals—including malathion in more than two hundred formulations—are sold. Liquid preparations of pesticides can be lethal in minute doses." 29

30

31

These data reflect prescribing practices, lethality of available drugs, and availability of alternative chemicals and methods. In the United States, antidepressants and pain relievers run neck and neck in number of fatalities—about seven hundred a year for each—but antidepressants are about five to six times as lethal per overdose. In 1990 amitriptyline (for example, Elavil) accounted for only 3.7 percent of suicide attempts, but for 12.7 percent of 1,492 deaths from drug overdose that were classified as suicides. Some years amitriptyline was the most often prescribed drug in the United States. 32

33

Antidepressants, ironically, were responsible for the greatest number of drug-suicide deaths (723), followed by narcotics (461), cocaine (342), and tranquilizers (322). Alcohol, which causes an estimated 4,000 acute and 200,000 chronic deaths a year) is ignored except as a contributor to another drug's toxicity. Tobacco, with some 390,000 annual notches on its belt, is not mentioned at all. These omissions are presumably the result of NIDA's pharmacologically irrational focus on "illegal drugs" rather than "dangerous drugs." The other problem with their data is that "mentioned" only means that the drug was mentioned by the reporting hospital. This implies, and usually means, a significant or lethal amount—but not necessarily. These may be drugs found in the toxicology screen or even remaining pills in a bottle. 34

For example, as far as I've been able to determine, there are no reports of fatal marijuana overdoses anywhere in the medical literature; yet N I D A cites thirty-one marijuana "mentions" in just one year's suicide overdose statistics.

More detailed, but less comprehensive, data on fatal poisonings from the A A P C C found that roughly half of drug-suicides took single drugs, half multiple drugs. Older data from state and county death records have found (1) fatal acetaminophen (Tylenol), codeine, chlordiazepoxide (Librium), diazepam 35

Suicide and Attempted Suicide • 241 (Valium), ethchlorvynol, flurazepam (Dalmane), meprobamate (Miltown), methadone, and aspirin overdose are usually found in multidrug deaths; (2) cyanide, T C A s , and carbon monoxide tend to be single-drug deaths. This reflects the greater toxicity and speed of the second group of substances.

NONMEDICINAL POISONS

USED

IN

FATAL SUICIDE ATTEMPTS

In the U.S. nonmedicinal poisons are responsible for about one-fifteenth as many suicide deaths as are medical drugs. The most common poisons are: automotive antifreeze (ethylene glycol), rubbing alcohol (isopropyl alcohol), acid toilet bowl cleaner (sodium hydrogen sulfate), corrosive drain unclogger (lye, sodium hydroxide), windshield fluid (methanol, wood alcohol), metal plating chemicals (cyanide), and pesticides. 36

WHAT ARE THE MOST DANGEROUS POISONS?

That depends on how you define "dangerous." You might base it on the smallest amount of chemical needed for a lethal effect (botulinum toxin). Or perhaps how quickly fatal it is (cyanide, nicotine, nerve gases). Or how many people a year die from its effects (tobacco, alcohol). Or the smallest ratio of therapeutic-to-toxic dose (lithium). Or the hardest to detect. For botulinum toxin, the lethal dose in mice is 0.03 ug/gm (microgram of poison per gram of mouse), or about one-seventh that of the most poisonous North American snake (Mojave rattlesnake); it was the first bacterial protein ever crystallized. The discoverer whimsically described it as a "white odorless protein of high molecular weight and unknown taste." However, the venom of the beaked sea snake is about five times more poisonous than the Mojave rattler and within spitting distance of botulinum protein. A n other snake, the Taiwan Banded Krait (Bungarus multicinctus), may be even more poisonous. 37

For medical drugs, one intuitively appealing measure of "dangerous" is the death rate per prescription. On one scale, the highest rate (for quinalbarbital) was defined as 100, rather like octane rating for gasoline; others are relative to it (the absolute number for quinalbarbital was 698 deaths/million prescriptions). The idea is simple enough: To measure the real-world lethality of pre-

242 • Geo Stone scription drugs by the ratio of deaths from their use to the availability of the drug. Note that this does not mean that a drug with a low fatal toxicity index (FTI) is safe; only that it is not used, for whatever reason(s), with fatal results very often, in relation to the number of its prescriptions. Besides important safety information for physicians (and users), more recently developed antidepressants produce a lower death rate than either older T C A s or (most) M A O I s ; they're less toxic—there are few overdose deaths using these as the only drug—and probably more effective against suicidal behavior. k

WHY ARE RESULTS OF DRUG OVERDOSE UNPREDICTABLE?

If you hang or shoot yourself properly you will almost certainly die; if you take a handful of pills you might die or you might be okay or you might be permanently injured. W h y is this, and what can you do to maximize the chance of a predictable outcome? BIOCHEMICAL INDIVIDUALITY

Biochemically, each of us is similar—and different. That's why some people are fatally allergic to penicillin or bee stings; why organ transplants require close tissue matches; why fingerprints are unique; why effective concentrations of medication vary from person to person. The range of biochemical individuality is not widely appreciated. For example, the rates at which people metabolize frequently used suicide drugs, tricyclic antidepressants (TCAs), vary ten- to thirtyfold. 39

Additionally, individuals' size and health vary. Since drugs/poisons require a certain concentration for their effects, the same amount will be less effective when distributed throughout a large person than a small one, all else being equal. But "all else" is rarely equal. For example, brains are fairly similar in size irrespective of whether one is a beefy 300-pound football player or a scrawny 150-pound writer. Thus a drug that is concentrated in the brain would require a reasonably similar dose for people of different size while a musclebound drug would require substantially different doses. A n d there are further complications. For example, most drugs are metab-

Suicide and Attempted Suicide • 243 olized and inactivated by the liver. However, prior chronic use of some drugs (for example, barbiturates, alcohol) revs up the liver, which then metabolizes drugs faster. This may have a protective effect against a subsequent drug— unless that drug is metabolized into its active form (for example, aspirin, heroin). A n d , of course, someone in poor health may well die from a dose that wouldn't have a serious effect on someone in good health. Thus, the same dose that would cause permanent injury in one person might make another vomit and be okay and a third one die. Further, multiple drugs are often taken, either therapeutically or suicidally. Sometimes these interact in unpredictable ways. For example, an antiulcer drug, cimetidine (Tagamet), decreases the body's ability to metabolize some other drugs, like theophylline (for example, Theo-Dur), increasing their toxicity. The medical literature is full of case reports citing novel or unusual drug interactions; there are ten thousand drugs currently in use and more new ones every year. m

SEX DIFFERENCES

While women and men absorb, distribute, and metabolize most drugs similarly, sex-related differences in drug clearance (removal from bloodstream) of over 100 percent are well known. The cause of such variation is that women are more subject to internal cycles and changes: menstrual, pregnancy, and menopause. These disparities are mosdy seen with psychotropic (mood/thought-effecting), heart/circulatory system, and antiinflammatory drugs, and are one reason why blood levels of drugs are increasingly often monitored. 40

UNCERTAINTIES ABOUT LETHAL DOSES

If you think about how the data are acquired, added uncertainties arise concerning the reliability of the published toxic/lethal doses. Animal test data often vary widely from one species to the next. For example, the lethal concentration of botulinum toxin is a thousandfold higher for rats than for mice. Thus, extrapolation of data from one species to another must always be tentative. Botulinum toxin is pretty strong stuff, deadly at one part in 33 million for

2 4 4 • Geo Stone 41

mice. For a 70 kg human, that would be about 2 milligrams (the standard aspirin tablet has 325 milligrams of aspirin, plus filler). Since there is sometimes a reluctance to poison large numbers of people acutely —or at to least publish the results—human poisoning data frequently are presented as single case reports, resulting from accidental or deliberate overdose. Many times, the amount of drug taken is uncertain, and about half of overdoses are drug mixtures, further confusing the toxicity picture. The concentration of the drug varies between tissues and over time. Some analytical techniques measure drug metabolites, some don't. The underlying health of different subjects is highly variable, as is the speed and quality of medical treatment. n

42

As a result, the lethal doses cited in medical reviews are generally in the form of a range of values rather than a nice, misleadingly simple single number. Furthermore, even this range differs from one authority to another. For example, the lethal dose of the familiar and thoroughly studied short-acting barbiturates is estimated to be 3-6 grams, 2-10 grams, 1-2 grams, and 1.6-2.2 grams by four different authorities. Adding more uncertainty, much larger overdoses are sometimes survived—20 grams of amobarbital in one case. Less common drugs/chemicals often have even wider ranges of human toxicity cited, because the data are too scanty for much precision. 43

45

44

46

47

Finally, some individuals will have adverse reactions to normally safe amounts of drugs/chemicals. An estimated 80 to 90 percent of drugs can cause a potentially fatal reaction in some people at therapeutic doses. A few of the more common ones are: penicillins, aspirin, A C T H (hormone), allergen extracts, nuts (food), eggs (food or in vaccines), milk (food), iodine mixtures (used in X-ray and other diagnostic testing), animal sera (vaccines), and procaine or lidocaine (local anesthetics). Approximately 1 to 3 percent of the A A P C C poisoning deaths were due to adverse reaction, that is, an unexpected lethal reaction to a normally safe dose. 48

Thus, the best anyone can do is to provide the range of toxic and lethal doses cited in the medical literature. Even so, there is no guarantee that any given dose of a particular chemical will have its predicted or intended effect.

Suicide and Attempted Suicide • 2 4 5 MORE PROBLEMS

As if this weren't enough, there are a large number of additional sources of uncertainty. For example, many drugs (for example, opiates, most antispasmotics, some antihistamines) slow the gastro-intestinal system. These drugs thus slow their own absorption, as well as that of other drugs. On the other hand, a few drugs (for example, the antivomiting drug metoclopramide, and cathartics) speed gastric motility. If many tablets are swallowed at the same time, they may clump together in the stomach or intestine in an unabsorbed lump, called a bezoar. Both these problems may have occurred in a death described by Steven Jamison: Bill was dying from A I D S and was told he had only weeks left. After arranging to get a prescription for a narcotic skin patch, he invited his family to his house to say good-byes. After two days with them, he said it was time, and went to his bedroom with his brother and his partner. He filled six syringes with Demerol (another opiate) to be used by them after he was unconscious, and applied twenty skin patches. He then swallowed over two hundred tablets of sedatives (Valium, Soma, Halcyon) and pain relievers, including morphine. He quickly lost consciousness and three hours later his brother injected the Demerol into Bill's thigh muscle. Seven hours later, Bill woke up and vomited, and fell into a light sleep. Probably the narcotics had slowed or stopped his digestive system, and the large number of unground pills may have formed a bezoar. In addition, the Demerol was not injected into a vein, because of his brother's fear of contact with Bill's blood. The family tried to decide what to do next; Bill's father wanted to use the plastic trash bag that Bill had prepared as a back-up. The brother disagreed, arguing that Bill would wake up and fight to remove it, but eventually agreed to give it a try. Bill did wake up, but they calmed him down. He said one last word, "okay," and died without a struggle. Such botched deaths—and there was no single cause here—are common in amateur assisted suicides. Even physician-assisted suicides are prone to failure where they're illegal. This is primarily because doctors fear that a large prescription for barbiturates—probably the best oral suicide drugs— will have legal or professional repercussions i f their patient uses it for that purpose. 49

50

246 • Geo Stone The sum of all these uncertainties is that you can't count on any drug to be either 100 percent safe or 100 percent lethal.

How CAN WE DISTINGUISH AMONG SUICIDAL, ACCIDENTAL, AND HOMICIDAL POISONINGS?

Murder by poison has a long and fascinating history. Not surprisingly, many of the leading practitioners have been physicians. This is because doctors have a tempting combination of knowledge, access to drugs, and, in some cases, the hubris to believe that they're smarter than the police. Between 1979 and 1995 the United States averaged forty-six homicidal poisonings per year. One reason for this low number is that there are very few, if any, poisons that break down fast enough or are lethal in low enough concentration to be undetectable by current analytical methods. Thus there is little likelihood of such a murder slipping by as a natural-causes death, if a complete autopsy is done. Poisoners who have specific victims in mind generally need access to the victim's food, drink, or medicine. Since the number of people with such access is usually small, the police can concentrate their efforts, with better than normal results. Homicidal poisoning comprised 0.16 percent of U.S. murders between 1980 and 1984. The British incidence of homicidal poisoning is fourteen times that of the United States (2.22 versus 0.16 percent). However, in England and Wales the total number of homicides between 1972 and 1982 (eleven years) was 5,323; this average annual rate of 0.8 per 100,000 is about one-tenth of the American rate.

Second, contrary to TV shows and crime novels, it is difficult to slip most poisons into someone's drink such that they will swallow it because: (1) many poisons are hard to dissolve; (2) they often taste terrible. Try dissolving some of your medicines in water or booze; if you succeed, taste the resulting drink. Not very encouraging for would-be poisoners, especially considering the amount needed. Arsenic is unusual in being almost tasteless and easy to obtain. Regrettably (for murderers), it is very easy to detect, both at the time and even years later. p

Third, undiscovered poisonings don't show up in the statistics. In recent years only around 10 percent of deaths in the United States have been autopsied, and not all of these include full toxicology screens. If a person with a serious preexisting medical problem dies in a manner consistent with the illness, a complete autopsy is highly unlikely. This is

248 • G e o

particularly true if the deceased is old, unless there are suspicious circumstances. Distinguishing between suicide, accident, and homicide is generally more difficult in overdose cases than with gunshot, stabbing, or hanging. This is because, with the latter groups there are frequently differences in the size, shape, angle, and location of the injury, depending on whether it was selfinflicted or not. For example, the bodies of most people who cut their own wrist or throat show evidence of "hesitation cuts": shallow wounds that often precede lethal ones. There may also be physical evidence, for example, gunpowder residue or rope fibers on the hands of a suicide. This sort of information is rarely available with overdoses. A n d so the determination of suicide, accident, or homicide in these cases is more often based on circumstantial evidence and a "psychological autopsy."

PRACTICAL STUFF

Recommended drugs; drugs to avoid; drug mixtures; tolerance; sources of drugs/chemicals. 52

SOURCES OF DRUGS

Your best source of prescription drugs is usually your doctor. If you are terminally ill, some physicians will prescribe enough pain medication to allow you to take a lethal overdose. Others, however, have ethical, professional, legal, or religious scruples against suicide even under these circumstances and will not help you. In that case, you may want to consider finding another physician: The last thing you need, in my opinion, is to have no choice about being kept "alive," hooked up to a mechanical ventilator, blood pressure maintained only by intravenous drugs, lungs vacuumed every hour, tubes in every orifice, until your body can't be flogged any further. This kind of torture continues to be seen, sometimes despite explicit instructions of patients and their families. You can easily obtain almost any medical drug in some countries: Brazil, Spain, Singapore, and Hong Kong have been recommended. Others have suggested Cyprus, Ecuador, Panama, and Mexico. Nevertheless, this seems like going to a lot of trouble since finding a sympathetic doctor is not diffi53

Suicide and Attempted Suicide • 249 cult. A n d a piece of rope or a plastic bag are workable alternatives (see Hanging and Asphyxia chapters). While you can buy just about any drug you want on the street, you can't be sure of what you're getting or how much it has been diluted or adulterated. As a result, the street is usually your least reliable source of suicide drugs. If you're a packrat, check the medicine cabinet; you might be surprised. You may also want to ask friends and family, if appropriate, for donations. Most—but not all—drugs are effective for at least a year beyond their expiration date if kept in a cool, dark, and dry place, though you might take a bit more to compensate for deterioration. If you're on good terms with a pharmacist, you may want to ask about the expected loss of strength of a particular expired drug that you have available. However, it is unrealistic to assume that eating even the entire contents of a medicine cabinet will necessarily be lethal, if for no other reason than the sheer variety of available drugs. q

WHICH DRUGS TO USE, WHICH TO AVOID

What follows are general observations. See Table 20.4 for the frequency that some common drugs are used in suicide and suicide attempt. "SAFE" DRUGS AND CHEMICALS.

To survive a suicide attempt with least likelihood of permanent injury, 1. Find a well-known drug that has relatively low lethality and few severe effects. Some examples are: acyclovir (Zovirax); aspirin (in low doses only, less than 150 mg/kg, which is thirty-two 325-mg standard tablets for a 70 kg (154 pound) person; caffeine; diazepam (Valium) and chlordiazpoxide (Librium) (don't mix the last two with other drugs); steroids; diuretics; N S A I D s (for example, ibuprofen); and A C E inhibitors (for example, captopril). 2. Don't take more than half the lowest known fatal dose—almost all of these drugs have killed people—and hope you don't set a new record.

250 • G e o Stone

3. Arrange to be found quickly, and avoid holidays when hospitals are short-staffed and are busy patching up drunk drivers and their victims. But there are no guarantees. Remember: 1 to 3 percent of drug-caused deaths are due to adverse reactions to normal doses. Ballpoint pen inks, bathtub floating toys, body conditioners are of the type of commonly available substances that are generally considered nontoxic in acute overdose. This does not mean that it is impossible to ingest a toxic or even lethal amount; only that it is difficult to do so. Anything is toxic if i n gested in large enough quantity or concentration (oxygen, water, sugar, salt—even chocolate). In addition, some of these household items may be toxic after chronic ingestion, for example, hair dyes or saccharin. A n d there is always the possibility of an individual's hypersensitivity to any particular substance. Finally, some can cause mechanical injury: One can choke on a chemically nontoxic golf ball or die of lung damage from inhaling baby powder—both of these have been done.

LETHAL DRUG OVERDOSE

If you really want to kill yourself using drugs, your best bet for a lowtrauma overdose is probably a central nervous system (CNS) depressant drug. These include opiates, barbiturates, and alcohol. Combining these with some fairly safe other drugs (among which are major tranquilizers, sedatives, and muscle relaxants) makes a mix that is considerably more lethal than either component separately. You should be aware that drug tolerance, the need for increasingly large doses to achieve the same effect, is especially common in drugs that affect the nervous system. This includes opiates, barbiturates, alcohol, tranquilizers, and sedatives (as well as stimulants such as amphetamine and hallucinogens like L S D ) . If you have been using any of them for a while, you will require a larger—possibly much larger—dose of that drug for any given effect, therapeutic or suicidal. This is a significant problem for dying people who are getting lots of pain medication and want to kill themselves with an overdose of the same drug. The lethal doses listed in medical literature will be

Suicide and Attempted Suicide • 251 underestimates in these circumstances; how much of an underestimate can't be predicted. Martin Delaney, the director of Project Inform, an advocacy group for people with A I D S , notes that he has seen situations where dying patients try to take enough intravenous morphine to kill themselves. "The problem is, they tend to do it gently and gradually and hope they will fade out without pain," he said. "Instead, they can develop tolerance, enormous tolerance. I'm talking about bags of morphine going into people." 57

Some drugs, especially those affecting the central nervous system, also show cross tolerance: use of one drug generates tolerance not just to itself but, to a lesser extent, to similar drugs. Generally speaking, the more closely related the drugs (or the mechanism of their action), the more cross tolerance. BARBITURATES. Barbiturates, especially the shorter-acting ones, are highly lethal in overdose, but are rarely prescribed since there are safer drugs with many of the same therapeutic effects. However, if you are terminally i l l , it should be possible to find a sympathetic physician who will prescribe these for "insomnia." On the other hand, you should not wait too long to start inquiries since many doctors will first prescribe benzodiazepines (for example, Valium, Dalmane) or SSRI antidepressants (for example, Prozac). In addition, many pharmacies no longer routinely carry any barbiturates other than phenobarbital (a long-acting antiepilepsy drug), adding further delay. 58

Since the physician will probably want to protect herself, she will likely prescribe much less than a potentially lethal quantity. Thus it may be necessary to get several refills. These drugs were quite popular with suicidal doctors: In 1974 almost 70 percent (139 of 203) of physician suicides via drugs/poisons used barbiturates. They invariably used short-acting varieties and/or mixed them with other short-acting C N S depressants, notably glutethimide (Doriden), a sleeping p i l l . But there's no need to be picky: A l l C N S depressants and sedative-hypnotics increase the toxicity of barbiturates. A few examples of these are: alcohol, opiates, diazepam (Valium), meprobamate (Miltown), and antihistamines. 59

60

252 • Geo Stone The organization Compassion in Dying (CID) recommends 6,000 to 9,000 mg (6 to 9 grams; 60 to 90 100 mg capsules) of Nembutal (pentobarbital) or Seconal (secobarbital) broken apart and mixed and suspended in about one cup of applesauce or melted ice cream. Barbiturates are bitter, so adding some sugar, honey, or artificial sweetener may be helpful. H a l f an hour before the main event, Compassion suggests three antinausea pills (for example, promethazine) and beta-blocking heart medication (for example, 80 mg propranolol), the latter to further decrease blood pressure. 61

r

The barbiturates must be eaten quickly, lest one fall asleep before swallowing a lethal quantity. Alcohol, taken after the barbiturates, will increase their toxicity. At these barbiturate doses, this is probably unnecessary, but, with smaller amounts, may be important. C I D reports that sleep occurs in five to seven minutes; death in twenty-five minutes to ten hours. There is no evidence of discomfort. Unless vomited, this is a reliably lethal dose; however, concurrent use of a plastic bag or tube tent may hasten death. (See A s phyxia chapter.) In the Netherlands, about four hundred people a year receive oral drugs for assisted suicide from physicians. The lethal ingredient is also pentobarbital (Nembutal), typically 9 grams (9,000 mg). But even with this large dose about 25 percent of the users survive for between two hours and four days. This may be another argument in favor of the simultaneous use of plastic bag/tube tent. ORPHENADRINE (Norflex, Disipal), an antihistamine, has been used in the Netherlands for euthanasia, mostly as an adjunct to barbiturates. By itself, orphenadrine is moderately but unpredictably toxic and quite unpleasant, and should not be used either for suicide or for a suicidal gesture. 62

(Darvon), an opiate-like drug, has also been used with barbiturates in the Netherlands. It's more toxic than orphenadrine, but shows cross tolerance with morphine and other opiates, and is thus less effective with people who are taking large amounts of narcotic pain drugs. ASPIRIN AND ACETAMINOPHEN. Both aspirin and acetaminophen are commonly found around the house and are dangerous in overdose, but neither is quick or painless. Acetaminophen has a specific antidote (n-acetyl cysteine), but it has to be administered prior to the development of fatal liver damage. There PROPOXYPHENE

Suicide and Attempted Suicide • 253 was at least one instance where this wasn't done because blood levels of acetaminophen seemed nondangerous, probably due to the overdose being from the sustained-release form of the drug. TRICYCLIC ANTIDEPRESSANTS (TCAS). Overdosing with antidepressants kills a lot of people, but if you're using them therapeutically, it may suggest that your decision on important topics like, say, suicide should wait until your judgment is not depression- or drug-influenced. Besides, "the first two to three weeks of treatment are the most critical, when the depressed patient experiences little benefit but maximum [unpleasant] side effects." A n d also has the largest supply of drug available. 63

64

There are three broad classes of antidepressant drugs: T C A s , which are fairly effective, but also quite toxic in overdoses; mono-amine oxidase inhibitors, M A O I s (rarely used anymore); and serotonin-specific reuptake inhibitors, SSRIs, which are similar to T C A s in effectiveness against depression, but are much less frequently used to commit suicide. T C A s have a multitude of other medical uses: insomnia, headaches, chronic pain, bulemia, and bed-wetting, among others. As a result, only a minority of their prescriptions are written by psychiatrists. This widespread availability, combined with their high toxicity—there's a 7 to 10 percent overdose death rate —makes them the prescription-drug group with the highest suicide body count. Amitriptyline (for example, Elavil) holds the recent single-drug record, primarily because it's more widely used than other T C A s ; but dibenzepin has about twice the death rate per prescription. T C A s are absorbed fairly quickly. Onset of convulsions generally occurs within three hours of overdose. Death, when it occurs, is usually due to some combination of heart failure, respiratory depression, and uncontrollable seizures. Lethal cases average around six hours between hospital admission and death. 65

The lethal intravenous dose is 0.34 to 0.41 milliequivalents (mEq) per pound (0.75 to 0.90 mEq/kg). This corresponds to about two teaspoons of Morton Lite or one teaspoon of the others. The minimum lethal volume is 12 to 14 ml (1 teaspoon is 5 ml, 1 tablespoon is 15 ml) saturated KC1 solution for a 70 kg (154 pound) person; however, it's more reliable to use excess. You can make a saturated solution by mixing about 40 grams (1.5 ounces) of KC1 into around 100 ml (4 ounces) of water. The quantities here are not critical. Stir for at least five minutes, or until no more seems to dissolve. Pour the liquid solution into an IV bag. Don't drink this though; it's not reliably lethal by mouth and will certainly make you very sick. 67

They also get a muscle paralyzing drug similar to the poison-arrow drug, curare. You'll probably have to settle for a muscle relaxant like Valium. The most likely problems include getting an IV line started or having it pull out. You can minimize the likelihood of the latter by taping it down. This is a relatively complicated method that may be difficult for someone to do alone, particularly if she is debilitated. It is, however, quick and lethal, and may be useful for someone who is bedridden and has a semipermanent intravenous line. APPLE SEEDS. If you really can't get what you need, as a last resort you might consider . . . apple seeds. If you crush a fresh apple leaf (or cherry, plum, pear, and some others) between your fingers, you should be able to detect the faint odor of almonds. This is the smell of cyanide. Apple seeds average around 0.6 mg hydrogen cyanide ( H C N ) per gram of dry seed. Since the lethal dose of H C N is estimated to be about 50 mg, you need around 85 grams (3 ounces) of dry seeds. This is around half a cup, which requires a lot of apples. However: 1. Plants are variable; eat enough—at least three times the minimum dose: Cyanide is not a drug on which to skimp, since it can cause brain damage in sublethal doses (see Asphyxia chapter for details). 2. The H C N must be liberated from the sugar it's chemically attached to. This occurs when the moistened seed is crushed, releasing an enzyme, emulsin, which does the job. Apparently this also occurs in the stomach, due to the hydrochloric acid there. In any case, you need to crush and eat these seeds fairly quickly, both to avoid evaporation of cyanide from the crushed seeds, and so as not to lose consciousness before ingesting a lethal dose. A blender or coffee grinder would be a good way to break up the seeds. 3. There are around 150 plants known to contain cyanide (vegetarians note!). Many of them have it in higher concentration than do apple seeds. For example, bitter almond seeds average around 3 mg/grams v

256 • Geo Stone (range 0.9 to 4.9), or five times the apple seed concentration. Cassava root is also quite poisonous unless processed to remove its cyanide. (I wonder how this was originally discovered.) 4. Cyanide, in the form of the alkali potassium salt is available as a metal plating solution, for example, "Cy-An-In"; the lethal dose of the sodium, potassium, and calcium cyanide salts is estimated to be 200 to 300 mg (0.07 to 0.11 ounce). 5. The use of cyanide is controversial: Some claim it is painless and quick, others that it is painful and quick. For what it's worth, cyanide is commonly used by suicidal chemists but rarely by physicians. However, this may reflect their respective easy access to different poisons rather than any other basis for preference. 68

w

The German Euthanasia Society recommends 1.5 grams potassium cyanide—about seven times the lethal dose—dissolved in a glass of cold water. Don't use fruit juice or soft drinks; their acid releases H C N prematurely (not that it will matter i f you drink it quickly). Kool-Aid has been recommended for those who don't like plain water. The same folks suggest placing 1 gram of a cyanide salt into a gelatin capsule and putting that inside a larger gelatin capsule. The idea is for at least the inner capsule to reach the gut before dissolving and releasing the cyanide. This is claimed to minimize stomach pain. Sodium cyanide works every bit as well as the potassium salt; calcium cyanide decomposes in water, but should do the job if used quickly. Effects are fastest if the stomach is empty and gastric acidity high. W i t h minimally lethal doses, death may take up to an hour. Symptoms include a bitter, burning taste; constriction or numbness of the throat; nausea and vomiting; disorientation; irregular breathing; unconsciousness; violent convulsions; protruding eyeballs; foam, often bloody, around the mouth. A l l in all, not a particularly peaceful exit, it would seem. 69

6. If you're in a hospital, and wired to monitoring devices, this (and most drugs) won't work fast enough and you'll probably be "saved"; but, if you're considered mentally competent, you can check yourself out "against medical advice" ( A M A ) and take care of business at home.

If you're trying to kill yourself be aware of the following: • Many drugs cause vomiting in overdoses. To limit this, you can eat lightly and take one to four antinausea/travel sickness tablets about an hour before the main event. Promethazine (Phenergan) is a common antinausea drug. The presence of food also increases the rate at which stomach contents are released into the small i n testine, where most food/drug absorption takes place. • If the drugs are in tablet or gelatin capsule form, you may want to grind or break them open and then try to dissolve them. A blender works well if there's other material (for example, milk) in it, but a coffee bean grinder or mortar and pestle is better if you're chopping pills dry; however, you'll probably still need to dissolve or suspend them in a liquid in order to swallow them. Powdered or dissolved drugs will be absorbed faster in your digestive system. As a result, it's important to drink the concoction quickly—within two to five minutes—to minimize the chance of losing consciousness before ingesting the entire dose. On the other hand, some may be too bad-tasting to easily swallow in this form. Test with a single tablet/capsule to determine this. Most solids will dissolve better in hot liquid than cold; some dissolve better in a mixture of alcohol and water than in water alone, but this varies from drug to drug. Experiment. Melted ice cream in a blender is a often a good choice because it will dissolve both fat- and water-soluble drugs as well as mask some bad taste. Remember that alcohol is a central nervous system ( C N S ) depressant and will increase the effect of other depressants. • If you have the "slow-release" formulation of a drug, grinding it to powder will usually be necessary.

258 • Geo Stone • The full lethal dose must be taken quickly; many suicides have failed when the attempter has lost consciousness before swallowing enough drug to finish the job. • If an overdose causes convulsions, the noise may attract attention. The frequency of convulsions varies, but is always a sign of severe toxicity. • If you use C N S depressants you may want to put a large plastic bag over your head, and fasten it (airtight, but not painful—rubber bands work well) around your neck; you will likely die of asphyxia. This combination of drugs and asphyxia substantially increases both the speed and likelihood of dying. A thirty-gallon trash bag holds (very approximately) enough air for half an hour. (Important. See Asphyxia chapter for more information.) You may want to wait until you begin to feel the effects of the drugs, but this increases the chance of falling asleep before applying the bag. It's better to use a larger bag or a tube tent. The latter, in particular, will minimize the chance of running out of air while still conscious. Whatever you use, it's also a good idea to practice with the plastic bag/tent until you're confident you can put it on and seal it—or remove it—when needed.

TREATMENT OF DRUG OVERDOSE

For most drugs, the standard treatment of choice consists of getting as much drug out of the stomach as possible, before it's absorbed. If the patient is awake and alert (and has not taken a drug likely to change that state within a half hour), 15 to 30 ml (1 to 2 tablespoons) syrup of ipecac (not "extract of ipecac", which is fourteen times more concentrated) should be swallowed along with at least one glass of water or clear soft-drink. This can be repeated after fifteen to thirty minutes if there has been no vomiting and no change in consciousness. Syrup of ipecac ' is the emetic-of-choice: It is more effective (but slower) than mechanical methods, and safer than chemical alternatives: saltwater, apomorphine, and copper sulfate. Liquid detergents (for washing by hand 72

3

Suicide and Attempted Suicide • 259 only, don't use liquid automatic-dishwasher or washing machine detergent) are a safe alternative if ipecac is not available. A dose of about 30 ml (2 tablespoons) of detergent caused vomiting in 83 percent of volunteers, compared to 97 percent with ipecac. Vomiting occurs an average of eighteen minutes after ipecac administration, but 11 percent do not vomit for more than thirty minutes. This can be important since only 30 to 60 percent of a drug dose is recovered in experimental animals when ipecac is given right after various drugs, and falls to 15 to 30 percent recovery after a one-hour delay in giving ipecac. In cases of large overdose of seriously toxic material, it's also appropriate (if there is no reason to avoid vomiting, see below) to try mechanical (fingers down the throat) induction of vomiting: It is important to get rid of as much poison as quickly as possible to prevent its absorption. However, vomiting is a potential disaster in unconscious or convulsing people, since inhaled vomit will cause lung damage and may be fatal. Inducing vomiting in people whose gag reflex is depressed may cause similar problems, and gag reflex may be chemically depressed or absent in alert patients. This is no joke. Some drugs that rapidly cause seizures or coma in overdose are: T C A s , strychnine, camphor, chloral hydrate, and isoniazid. 73

The use of some other poisons also contraindicates vomiting: in general, if the poison is likely to do more damage from coming back up than from staying in the stomach a few more minutes, vomiting should not be induced. Poisons that fall into that category are (1) caustics: lye, automatic-washing detergents, most drain cleaners, strong acids; and (2) liquid hydrocarbons (furniture polish, gasoline, oils). If induced vomiting fails or is inappropriate, gastric lavage ("stomach pumping") is often used. This is done by running a lubricated 1 cm tube through the nose into the stomach. Small volumes of water (50 to 100 ml) are pumped in (to avoid pushing drugs into the small intestine) and pumped back out. The process is repeated until the removed gastric contents are drug-free. Use of "activated" charcoal (not what you use for barbecues) seems to be more effective than syrup of ipecac for limiting absorption of many chemicals and is the home remedy of choice in parts of Europe. It is of little or 76

no value against mineral acids or alkalis, cyanide, elemental metal ions, many pesticides, and wood alcohol, among others. It is effective against many medical drugs, including T C A s , aspirin, acetaminophen, and barbiturates. Since activated charcoal absorbs drugs, it should not be used at the same time as ipecac or specific drug antidotes, such as n-acetyl cysteine (an antidote for acetaminophen). Because it is safer than either ipecac or stomach pumping, and most overdosed people get to the hospital too late to remove much drug by any of these methods, activated charcoal is becoming the standard treatment in U.S. hospitals as well. Activated charcoal is probably best acquired as a commercial, premixed slurry. It can be mixed at home from powder and water, but must be mixed thoroughly. Flavoring may be added to improve palatability. Dose is 1 gram/kg of body weight (70 kg equals 154 pounds). This is a good thing to keep around the house. Cathartics (diarrhea inducers) are often used to decrease drug absorption by limiting the time it remains in the gut, but the effectiveness of gut decontamination more than one hour post-ingestion is unclear. In one study of suicidal overdoses, people got to the emergency room an average of 3.3 hours post-ingestion, ipecac did not significantly change the outcome for those in whom it was used (people who were alert), and stomach pumping only helped when done within an hour of ingestion. More invasive methods may be tried in cases of severe toxicity. One of these is "forced diuresis," which pushes the kidneys to pass more urine (and drug), typically by diuretic drugs or by fast intravenous fluid infusion. If there is kidney failure, hemodialysis may be necessary. Each of these procedures has hazards associated with its use, the details of which are available in any medical text on poisoning. 77

SUMMARY

A l l in all, drugs can be—if you know what you're doing—a reasonably safe suicidal gesture roughly on a par with nonlethally-intended wrist cuts. Pick a low-toxicity drug, preferably one you know you're not allergic to; take a

Suicide and Attempted Suicide • 261 dose that won't do major damage even if help is delayed; call for help before the drug affects you; have activated charcoal available. If you're trying to kill yourself, be aware that most drugs take hours to be fatal—but you can't rely on it—and are not pleasant. Read the list of symptoms again. Convulsions, which are common, may make noise and attract attention. Spontaneous vomiting, if it occurs, may leave you with few further i l l effects; or with an almost-lethal dose and permanent injury; or you may choke to death. Central nervous system depressants are probably the least traumatic, though not particularly fast, lethal drugs. Since these depressants cause unconsciousness, they may be combined with plastic-bag or inert-gas asphyxia, drowning, intravenous potassium chloride, or carbon monoxide for a faster and more certain death.

Different uses of similar drugs: M o s t phenothiazines (for e x a m p l e , c h l o r p r o m a z i n e

D e s p i t e these limitations and complications, these data are useful, particularly f o r physicians wanting to prescribe a less t o x i c m e m b e r of a m o r e or less interchangeable class of drugs, f o r e x a m p l e , antidepressants.

At least o n e d r u g , c l o m i p r a m i n e , has b o t h a higher heart toxicity along with a l o w t o x i c -

ity index; that is, it kills fewer p e o p l e than e x p e c t e d , based on the n u m b e r of prescriptions, despite being quite t o x i c . W h y is this? It turns o u t that c l o m i p r a m i n e is used m o r e often in obsessive-compulsive patients than in ( m o r e suicidal) d e p r e s s e d o n e s , and tends to be used m o r e with hospitalized patients, w h o are u n d e r c l o s e r s u p e r v i s i o n , than with o u t p a t i e n t s . T h u s its l o w toxicity index seems to be due to its prescribing profile (Farmer, 1989). T h i s example of a mismatch b e t w e e n "toxicity" and "toxicity index" also s u p p o r t s the n o t i o n that s o m e o t h e r drugs' high toxicity index might n o t be due to high intrinsic toxicity, but rather to the d r u g p r o v o k i n g its o w n use in s u i c i d e . T h e r e have been claims that this o c curs with fluoxetine (Prozac) and maprotiline (Ludiomil), but the evidence is controversial (Baldwin, 1991; Frankenfield, 1994). H o w e v e r , since t h e r e is g o o d r a n k - o r d e r agreement between fatal toxicity index and the lethal d o s e in mice ( M o l c h o , 1992)—in w h o m p r o v o c a t i o n of suicidal behavior is n o t a s e r i o u s p r o b l e m — i t seems likely that m o s t of the higher toxicity index f o r T C A s is d u e to their higher inherent toxicity c o m p a r e d t o o t h e r antidepressants. m

A principle of p h a r m a c o l o g y is that "the r e s p o n s e to multiple drug therapy is n o t equal

to the sum of the k n o w n responses to separate administration of each d r u g " (Sigell, 1970). T h i s is similar to the everyday situation w h e r e t w o w e l l - k n o w n chemicals are mixed; the result may be a dangerous surprise.

21 ELECTROCUTION

Electrocution is an effective, but infrequently used, method of committing suicide. It is not a good choice for a suicidal gesture. The potentially lethal effects of electricity on the body include heart stoppage, respiratory failure, and burns. LETHAL INTENT: High MORTALITY: 40 to 90 percent PERMANENT INJURIES: Moderately likely PROS AND CONS OF SUICIDE BY ELECTROCUTION

Pros: • Not much physical strength or dexterity needed • H i g h fatality rate • H i g h (not household) voltage and current usually causes quick unconsciousness Cons:• Scarcity of data on suicidal electrocution—most of our information is extrapolated from accidents • Frequent permanent injuries from high-voltage accidents • Electricity is mysterious to many people • May be hazardous to innocent bystanders or rescuers The major topics of this chapter are the medical and physiological effects of electricity. Also discussed are sources and types of electricity, as well as methods and impediments to suicidal electrocution.

How DANGEROUS IS ELECTRICITY?

This may seem a silly question, but electricity is usually invisible and, for many people, mysterious. As a result, it's not widely known that consequences of electric shock often depend on how quickly help is available. This is because death is commonly due to the shock-induced stoppage of heartbeat or breathing—which are frequently reversible if there is prompt medical intervention, usually C P R (cardio-pulmonary resuscitation). 4

The medical literature cites a wide range (5 to 50 percent) of mortality rates in known electrical accidents, but since minor shocks are rarely reported, the accuracy of even this figure is questionable. In one recent study only 3 percent of hospital patients admitted with injuries from high voltage (greater than 1000 volts; found in high-power transmission lines and some industrial uses) died. But this didn't include those dead at the scene or dead on arrival. There is about a 90 percent fatality rate in suicidal electrocution attempts using household and high-voltage current. Use of electric stunning devices is about 40 percent fatal. The frequency of long-term injury is unknown with suicide attempts, but occurs fairly often in accidents. M u c h depends on the type and duration of electric shock. The three most common sorts of long-term injury are: 1

• burns, typically from high-voltage power transmission; • direct neurological (brain/nervous system) damage, generally from lightning or high-voltage power transmission; • indirect brain damage resulting from breathing paralysis, which can be caused by high- or low-voltage power, or lightning. There's more detail on these in the section on long-term injury.

Suicide and Attempted Suicide • 267 The invention of the Leyden jar, an early type of capacitor, in 1746 first permitted electricity to be collected and stored. Word of this simple device spread quickly and electric shocks became a popular novelty in fashionable circles. Kings had their own court "electricians." In one spectacle, seven hundred monks were connected to each other and to a Leyden jar. W h e n the jar was discharged, they jumped into the air "with a simultaneity of precision out-rivalling the timing of the most perfect corps de ballet." 6

Benjamin Franklin proved that lightning was identical to electricity from the recently invented Leyden jar (and not a gas explosion, as previously believed) in his famous kite experiment—flying a kite in a thunderstorm and getting a spark from the ground end of the kite-string (attached to a metal key) to charge a Leyden jar—the repetition of which electrocuted a number of less fortunate subsequent experimenters.

DEMOGRAPHICS SUICIDE. Suicide by electricity is rare: There were fourteen known suicidal electrocutions in the United States in 1994; the 1979 to 1994 average was eighteen, which is 0.06 percent of the roughly 30,000 official suicides annually. Of 220 electrocutions in Dade County, Florida (Miami), 217 deaths were accidents, 2 suicides (0.9 percent), and 1 a homicide. 7

Electrocution is the fifth leading cause of occupational fatalities among men in the United States; power lineworkers are electrocuted at a rate of 33.4 per 100,000 per year; electricians 8.3 per 100,000 per year. Construction workers are also at high risk for electrocution. The overall accidental electrocution rate is approximately 0.54 per 100,000 per year (1 per 185,000) in the United States. ° Nonlightning electrical deaths per year in the United States have decreased steadily from 1,140 in 1970 to 640 in 1990, but about 3 to 5 percent of burn center admissions in the United States are caused by high-voltage electricity. While a large majority of severe electrical injuries are due to high voltage, about half the deaths are from low voltage (arbitrarily defined as anything less than 1,000 volts). This low voltage is generally household (wall outlet) current, 110 to 120 volts A . C . (or 220 to 240 volts A . C . for electric clothes dryers, larger air conditioners, etc.) at 60 hertz (cycles per second) in the ACCIDENTS.

In about 15 percent of electrical accidents there are also injuries from falls. LIGHTNING. Lightning strikes the earth around one hundred times per second. There were seventy-four deaths due to lightning in the United States in 1995; the 1979 to 1995 average was eighty-three. Lightning kills around 40 percent of the people it hits. Nonfatal injuries are discussed later in this chapter. d

The speed of sound in air is around 1,100 feet (335 meters) per second; thus the time difference betweeen seeing a lightning flash and hearing the shock wave is about five seconds per mile (3 secs/kilometer). If you don't hear the thunder, either the lightning's very far away or you got hit by it.

Not unplugging electrical devices under repair can be fatal. A study found that, "About half the [electrocution] deaths of women over sixty were due to the use of metal scissors in the investigation of connectors of electric irons and kettles." One woman who was killed in this manner had pulled the plug from the wall socket; unfortunately, her three-year-old son had reinserted it. 6

EFFECTS OF ELECTRICITY

There are three types of fatal injury directly caused by electricity (an electric shock may also kill by knocking people off ladders or otherwise into danger): • Burns; • Interference with heartbeat or breathing by means of continuous small electric shocks, none of which may be individually harmful; • Paralysis of heartbeat or breathing from a single large electrical jolt.

Suicide and Attempted Suicide • 269 Lethal burns are most often due to high electrical current passing through the body. Such current is most commonly found in power lines and some factories. Household-voltage electricity rarely kills by this means, though it may cause burns, even charring, if there's prolonged contact. 18

L o w A . C . voltage causes repeated muscle contractions while the electrical circuit is complete, which may prevent effective breathing and heartbeat. Such shock can make various areas of heart muscle beat without coordination (fibrillation). Breathing usually resumes when electrical contact is broken, but the heart is more sensitive to electrical interference and generally does not recover spontaneously from ventricular fibrillation (uncoordinated contractions of the portion of the heart muscle which pumps blood through the body). Promptly applied cardiac defibrillation ("electroconversion") may restore normal heartbeat/ but is rarely available soon enough to make a difference. In the absence of C P R or spontaneous recovery, a fibrillating heart starts to die in sixty to ninety seconds. C P R extends the possible intervention time by at least a few minutes. A single large electric shock can paralyze the heart, the muscles responsible for breathing, or the respiratory-control center in the brain. This can occur from lightning, or high-voltage power lines/sources. Prompt C P R can maintain many such people until their own heart and breathing restarts. Such recovery is much more likely than in cases of ventricular fibrillation. The following table summarizes the types and severity of injury from electricity. 19

achieve (if that's the right word) electrocution, the electrical current pathway must go through organs that are both vital and susceptible to electrical disruption. The ones that best fit this description are the brain, spinal column, heart, and respiratory muscles in the diaphragm. ELECTRICAL PATH. T O

The electrical pathway is thus critical: Head-to-limb is always dangerous because it goes through the brain, and, depending on which limb, possibly the heart. Similarly, a right-hand-to-right-foot pathway is less hazardous than a left-hand-to-left-foot or a hand-to-hand circuit, since the latter two are more likely to go through the heart. CELL AND TISSUE DAMAGE. A t a cellular or tissue level, electricity causes damage by two mechanisms: (1) It depolarizes (fires or sets off) nerve and muscle cells by mimicking normal nerve and muscle electrochemical conduction, but does so with greater intensity, so that both nerve and muscle tissue may be overstimulated, and exhausted or injured. Direct current (D.C.) generally causes a single muscle contraction and/or nervous system depolarization; alternating current (A.C.) does this repeatedly. This depolarization is not directly fatal or even necessarily injurious. However, since the impulse to breathe is sent out by the brainstem, trans-

Suicide and Attempted Suicide • 271 mitted by nerves, and carried out by muscles, prolonged electrical interference with any of these could be lethal. Similarly, a big electrical shock may severely depolarize and paralyze the heart muscle. Lesser, but continuing, shock can interfere with the exquisitely synchronized flow of nerve impulses within the heart, and cause its muscle cells to beat chaotically, and thus be unable to pump blood. A n d we're back to fibrillation, which is fatal unless quickly reversed. (2) Electric current moving through resistance generates heat. This heat causes cell and tissue damage, similar (but not identical) to fire burns. More on this later.

HOUSEHOLD ( A . C . OR ALTERNATING CURRENT) ELECTRICITY

To be electrocuted, three things must happen at the same time: (1) There must be an electric charge or current, (2) the electric charge must go through you, and (3) the electric charge must return either to "ground potential" or complete the circuit by returning to the source. Thus a bird can land on an uninsulated high-voltage wire with no i l l effects because each of its feet is at the same voltage, that is, there is no voltage difference. What is "ground"? It is something that has the same electrical level ("potential") as the earth. Grounds or grounding paths are conductors that are physically connected to the earth, either directly or through other electrical conductors. Examples are metal (but not plastic) pipes, damp concrete, radiators, grounded appliances, water, etc. If you are connected to any of these, electricity can flow through you to the earth with potentially lethal results. If there is no such connection, you are insulated and pretty safe. Thus someone wearing thick boots might pick up a (single) bare wire carrying 120/240 volts with no i l l effects—unless the boots were steel-toed, used metal nails, had worn-down soles, or were wet. How SMALL A CURRENT CAN YOU FEEL? The threshold for feeling household (60 cycle-per-second) alternating current, is between 0.5 and 2.0 milliamps (mA), depending on individual sensitivity. This minimal current feels like a tingle and causes no direct injury, but may startle someone into losing balance or dropping an electrified object into a more dangerous position, for example, into the bathtub. ELECTRICAL GROUND.

rent can cause numbness (2 m A ) , pain (1-4 m A ) , and muscle spasms (5 m A ) . Somewhere between 6-22 mA, these muscle contractions are uncontrollable and the victim cannot let go of a grasped object, often the electrical conductor. The fundamental reason this happens is that voluntary muscles, like those in your hand, normally contract in response to small electrical signals transmitted through the nervous system; the hundred-timesstronger external electrical signal totally overwhelms the nervous system's control. 23

8

This current level is sometimes called, rather confusingly, both the "let-go current" and the "no-let-go current," as well as the "hold-on current." Whatever the name, it occurs because the grabbing muscles (flexors) are stronger than the releasing muscles (extensors), as can be easily demonstrated with your hand: Make a fist; now wrap the other hand around the fist and use it to try and keep the fist from opening. This is also why an alligator's jaws, which are strong enough to crush bones, can be kept shut with bare hands. Some electricians and repair people—most older ones—have the habit of touching any possibly-live electrical device with the back of their hand before attempting to pick it up: Even if they get a shock, they won't involuntarily grasp it and be unable to let go. Since other muscles also go into involuntary contractions from electrical overstimulation, people will die from inability to breathe (tetanic asphyxia) if a low current path goes through the respiratory muscles (head-to-leg, arm-to-arm, or arm-to-opposite-leg). Thus, not being able to let go of an electrical conductor may well make such relatively small current more dangerous than a larger current that knocks you away from the conductor. In one instance a 21 volt A . C . microphone electrocuted a pastor who was waist-deep in a water-filled concrete baptismal fountain. Death was attributed to drowning, as a result of electrical paralysis. However, the most common reason for death from low-voltage (household) alternating current is ventricular fibrillation. This is caused by somewhat higher current, starting around 100 mA for one-tenth of a second, which will induce the different parts of the heart to beat out of synch with each other, as normal nerve conduction within the heart is disrupted. This quivering, uncoordinated mass of heart cells cannot pump blood, and 24

25

26

Suicide and Attempted Suicide • 273 unless some circulation is restored quickly (within approximately five minutes ) by C P R or defibrillation (a big electrical jolt, typically five amps at 440 volts D . C . for 0.25 seconds, that makes all the heart cells simultaneously contract, and thus "resets" them to the same state), brain damage and death follow. C P R will extend the time during which defibrillation can be successfully applied, but hearts in ventricular fibrillation rarely convert spontaneously to normal rhythm. 27

The minimum amount of current needed to provoke fibrillation depends on both individual sensitivity and on how long the current is applied. One source calculates the minimum current as 116 mA multiplied by the square root of the current duration. Thus a four-second shock could result in fibrillation with a current of as little as 58 m A , while 116 mA would be needed for a one-second shock. By way of comparison, the current going through a small 7.5 watt lamp at 120 volts is 62.5 milliamps; 625 milliamps is drawn by a 75 watt lamp. The liklihood of fibrillation increases with current, up to the point where the heart stops altogether. A 2,000 mA (2 amps) or greater jolt can make the heart, basically, stop (cardiac standstill). However, it will often restart spontaneously when the current stops. Thus, higher amperage current, which can cause the heart to stop, will be less dangerous than lower amperage, which sets off fibrillation. Fifteen amps of current passing through the diaphragm (muscles below the lungs) can paralyze breathing (respiratory arrest), but paralysis also depends on the electrical path; lesser current through the head may have the same effect by knocking out the respiratory center in the brainstem. In both cardiac standstill and respiratory arrest, C P R has a good chance of maintaining circulation long enough for breathing and heart function to restart. 28

29

BURNS DUE TO HOUSEHOLD ELECTRICITY

The third mechanism of death from electricity is burns. Most low-voltage burns are due to an inability to let go of the electrical conductor. Such prolonged muscle contraction is typically a problem with A . C , but not D . C . current. In one study, fourteen of fifteen low-voltage burns occurred for this reason. 30

274 • Geo Stone If the electrical conductor touching the body is small, for example the end of a wire, the current enters the body at a correspondingly small site and with high current density, which promotes local tissue damage. Sometimes this looks like a bullet wound or a thermal burn. CONTACT AREA WITH THE ELECTRICAL SOURCE.

If the electrical contact is over a large area, as is the case in most bathtub electrocutions, there may be no external mark at all. This is because (1) water conducts electricity over much of the body, thus lowers electrical density; (2) the water acts as a heat sink, absorbing most of the heat produced by electrical resistance, at least with low voltage.

HlGH-YOLTAGE A . C .

ELECTRICITY

"High voltage" is arbitrarily defined as more than 1000 volts. Power lines into houses are generally 220/240 volts A . C ; high-power lines in residential and industrial areas are often at 7,620 volts A . C ; power lines from generating plants sometimes carry over 70,000 volts A . C . In high-voltage shocks (for example, from high-voltage transmission lines or lightning) death is most often due to respiratory paralysis, and/or heart stoppage, while ventricular fibrillation is infrequent. Most characteristic of high-voltage electrocution is the presence of burns: 96 percent (89 in 93) of high-voltage deaths in one study had visible burns (compared to 57 percent of deaths from electrocution due to less than 1,000 volts). In the survivors, burns are often the most severe injury, especially with A . C . current. In one case, 31

... a man aged twenty-two was electrocuted while attempting to steal copper cable. He was found at the foot of a high-tension pylon with a pair of wire cutters beside him. He had been seated on an iron bracket at the top of the pylon and had already cut several lengths of wire. He had worn thick P V C gloves to protect himself from the 6,000-volt supply. Arcing occurred and he sustained grave burns of his body especially of the wrists, upper arms, and chest. Although his clothing had been damp it was set on fire from the flash.This had probably been the cause of the thermal burns of

Suicide and Attempted Suicide • 275 his abdomen and thighs. Although he had fallen about 20 feet this had not caused additional injury as the ground was soft.

32

Sometimes the temperature exceeds the flash point of muscle, which then ignites and burns, rather like a piece of meat over a hot charcoal fire. As you might suspect, such electric current through the skull is particularly gruesome. In some cases, the skull splits open, and the eyes are blown out of their sockets by the steam pressure from the boiling brain. The tetanic contraction can be so severe that it is capable of causing bones to break and muscles to tear from their attachment points in bones. The upper arm bone is most frequently broken. Despite the above, the actual cause of death in the majority of high-voltage electrocutions is paralysis of the respiratory center of the brainstem, which keeps you from breathing on your own, and results in asphyxia. 33

LIGHTNING INJURY

Lightning bolts average around 30,000 amps, millions of volts, and 20,000 degree C temperature, but only 1/10,000 second duration. Paralysis of the heart, and/or of the respiratory center in the brainstem, are the most dangerous lightning injuries. Either of these will cause death in about five minutes in the absence of C P R . Since C P R keeps some oxygenated blood moving, it significantly increases chances for spontaneous recovery, especially if it is started quickly, say within a minute. About one-third of the people struck by lightning die within a few minutes; relatively few die later of their injuries. 34

35

36

Severe burns are infrequent from lightning strikes, despite the several-thousand-degree temperatures involved, because of the short duration of the strike doesn't transfer much heat. However, there is a curious and characteristic faint burn pattern found about half the time in lightning victims, called "arborescence"; the pattern is fern-like. Experts disagree concerning how it's formed. Some claim it's caused by heat damage (denaturing) to red blood cells in veins or arteries; others argue that it marks the trail of nerve damage. More serious burns can occur if the victims are wearing, or are near, metal (coins, jewelry, belt buckles, fences, etc.) when struck (iron and steel objects h

may become magnetized), or if their clothing ignites. On the other hand, if the skin is wet with rain or sweat, clothing tends to be blown off by the explosive evaporation of the liquid. Nervous system injuries, such as blindness, confusion, amnesia, and tinnitis (imaginary ringing sounds), are common, but usually not permanent. In one study, 86 percent of surviving lightning victims had amnesia and 19 percent were temporarily paralyzed. 38

There is a certain capriciousness to lightning injuries: W h e n two men were driving in a dog cart during a storm, the vehicle was struck and both men fell out of it. Five minutes after the flash their bodies were found lying side by side on the road.The seat of the cart was beneath them and the driving apron was still around their legs. O n e of the men had an extensive burn over his chest and abdomen, and circular holes of from 1/16 to 1/4 inch in diameter scattered over the burnt area. His metal collar stud had fused and the underlying skin was deeply burned.The other victim had no external injury. The horse was uninjured and trotted home. 39

High voltage is not in and of itself particularly dangerous; amperage is much more significant. For example, the output voltage from an automobile ignition coil is, typically, between 15,000 and 50,000 D . C . volts, but the current is less than 1 milliamp. As anyone who has been shocked by spark plug voltage can attest, it is an unpleasant jolt—your eyes light up like a pinball machine—but not normally a killer.

DIRECT CURRENT Direct Current (D.C.) electricity occurs naturally in lightning, static electricity, and electric eels; somewhat less naturally in batteries, capacitors, electric trains, and other human artifacts. Direct current is less dangerous than A . C . for two reasons: (1) It does not cause multiple tetanic muscle contractions; thus one can let go of a D.C.-energized wire (though the single jolt it does cause can result in broken bones from the force of the contraction, injury from falls, burns, cardiac standstill, or respiratory arrest); (2) It is less

Suicide and Attempted Suicide • 277 likely than A . C . to cause ventricular fibrillation. As a result, D . C . current of less than 80 mA is claimed to have no harmful physiological effects. The lowest D . C . voltage that has caused death (from external contact ) seems to be 24 volts. This is the voltage of two car batteries in series (end to end). A man was found on the wet ground under his battery-powered milk truck. He had two small electrical burn marks, one on the right shoulder, the other on the right hip. The death remains a bit of a mystery, since the batteries, when examined, only leaked 5 mA, far below what is considered dangerous. Nevertheless, the fact remains that a previously healthy man died under circumstances and with signs of electric injury, and nothing else of significance was found on autopsy. 40

ARC CURRENT

A i r is a poor electrical conductor, but sufficiently high voltage will jump across an air gap; the higher the voltage, the larger the gap that can be jumped. This phenomenon accounts for the spark in a spark plug; why static electricity will jump from one person to another without them touching; and, of course, what occurs in lightning. The approximate air gaps are about 30,000 volts per c m with round electrodes, and around 12,000 volts per cm with needle-point electrodes. 41

j42

In other words, you can get zapped by being close enough to a high-voltage source; physical contact is not necessary. "A man was loading hay on to a stack in damp conditions; there were frequent showers. As the stack grew, the man came nearer and nearer to overhead cable, carrying 20,000 volts. His clothing was damp. Arcing occurred and he fell off the stack and broke his neck. He had not touched the cable but there was an electric entrance mark behind the tip of his right ear." As anyone who has done arc welding knows, sustained electric arcs produce sufficient heat to melt metal. The temperatures can reach 4,000 degrees C (7,200 degrees F). This is hot enough to vaporize most metals, which condense on the first cooler object they touch, and so a characteristic of arc burns is the "metallization" of nearby skin. Since the bright light of an arc causes the eyelids to close reflexively, there may be metal-vapor crow's feet visible around the eyes. Once an arc is established, it can be 43

k

278 • Geo Stone made longer without additional voltage. Thus, falling down might not break the electric circuit. These arc burns are some of the most traumatic of injuries. In addition, arcing heats the nearby air, which rapidly expands causing an explosion, that is, thunder. A 25,000 amp arc generates a pressure of almost 500 pounds on someone two feet away. Burns from such an arc—remember, this is hot gas and metal vapor—can be fatal even several feet away, and severe burns from even ten feet away are common. 44

LONG-TERM INJURY

There are three common types of long-term damage from electricity: • Tissue damage and destruction from burns; • Direct neurological damage; • Indirect neurological damage. TISSUE DAMAGE AND DESTRUCTION FROM BURNS is most common with high voltage, but can also occur with low-voltage A . C . after prolonged contact. A r terial injury may occur and the resulting hemorrhages can be both sudden and severe, because (a) the damaged arteries are brittle and can't be clamped off without breaking, and (b) the arteries are sometimes damaged beyond areas of obvious tissue injury Eye damage, including corneal burns and optic nerve injury, may be permanent. Cataracts (clouding of the lens of the eye), probably caused by heat, may appear from weeks to years after highvoltage contact to the head. Interestingly, electrical burns tend to heal better than similar nonelectrical ones, and they are somewhat less painful because of greater nerve damage from electricity. Nevertheless, such burns may be severe enough to require amputation of the affected limb; this occurs in 18 to 45 percent of high-voltage injuries. As with thermal burns, infection is the most common cause of delayed death. 45

Suicide and Attempted Suicide • 279 prisingly, it is most frequent when the head is in the electrical path. However, there are cases where significant early and delayed brain injury occur even though the brain is not in the current path. These injuries may persist for more than a year. Amnesia and confusion are also common. Personality change and deafness have occurred, as has spinal cord damage, leading to paralysis. In one study, eleven of twenty-two patients with low-voltage burns had neurological symptoms, generally temporary. However, another study found that twelve in sixteen survivors of electric-current injury had neurological problems after one year, while only four in eighteen who had flash or arc injuries "without passage of current" had long-term damage. By comparison, in the high-voltage group, only twenty of sixty-four recovered completely. Injury symptoms include paralysis, anxiety, depression, outbursts of aggression, difficulty with writing and/or speech, and loss of taste. INDIRECT NEUROLOGICAL DAMAGE. The brain is very sensitive to lack of oxygen. If the oxygen supply is cut off due to heart or breathing stoppage, brain tissue starts to die within five minutes or so. Even if heartbeat and breathing are restored, such brain damage tends to be persistent. For more details, see chapters on hanging and on asphyxia. Since there's little information on suicidal electrocution injuries, we are pretty much limited to accident data. In a large study of electric-lineworker injuries in France: 50

• 2.4 percent were immediately fatal; another 0.9 percent died later as a result of their injuries; • 7.2 percent lost consciousness; • 93 percent suffered burns; • 19 percent of survivors had disabling or disfiguring scars; • 7.3 percent had neurological or psychological damage; • 21 percent were permanently disabled. This suggests that unplanned high-voltage electrical injury is neither reliably lethal enough for suicide, nor sufficiently nontraumatic for suicidal gestures.

280 • Geo Stone JUDICIAL EXECUTION

57

n

The State of New York introduced electrocution in 1890. In the first execution, electrodes were attached to the victim's head and lower back, salt solution was utilized to improve conduction, and a 1,600 volts A . C . at 150 cycles-per-second (hertz) current was applied. After seventeen seconds the man was declared dead. Congratulations were premature, however, since thirty seconds later, he began to breathe again, followed by "groaning and foaming at the mouth." The current was restarted and kept on until the "body of the victim steamed" and he finally died. Other early attempts were similarly bungled. 58

The procedure was gradually "refined" so that in our present enlightened day, one electrode in the shape of a helmet is attached to the head, the other to the right leg. 2,000 volts at 60 Hz are applied for three to five seconds (intended to cause unconsciousness), followed by 250 to 500 volts (to cause heart and/or respiratory stoppage) until death ensues. At the site of the electrodes, third-degree burns may occur, producing smoke and charring. In prompt autopsies, the brain steams and has a temperature as high as 63 degrees C (145 degrees F) and the cortex is covered with blood from ruptured vessels. 0

SUICIDE BY ELECTROCUTION

Suicide attempts by electricity, though rare, are about 90 percent successful. Some methods that have been used to commit suicide follow: 1. Climbing a high-voltage pylon or pole and grabbing (or attempting to grab—see section on electric arcing) a high-voltage wire. Typical injuries include burns, heart and/or respiratory stoppage, and injuries from the fall. The initial jolt causes unconsciousness, and death is highly likely. A variation on this is sometimes used by people who don't like heights: Rather than climbing, they wrap a wire around some part of their body (often around a wrist, but in at least one case, around the neck) attach a weight to the other end of the wire and toss the weight over a high-voltage line, which is an uninsulated, bare wire. In this situation there is no fall from a height, but the electrical contact is prolonged. Bare feet and damp soil are

Suicide and Attempted Suicide • 281 helpful but generally not necessary. Enough heat is generated to often amputate the wire-wrapped part of the body. A thin wire is at risk of melting before you do, so it's important to use the thickest one you can handle. There are occasional reports of people being electrocuted as a result of urinating onto the high-voltage electric train rail, though these are probably not deliberate suicides. Despite its high lethality, people sometimes survive high-voltage suicide attempts with nothing but third-degree burns and permanent injuries to show for their trouble. 2. A simple electrocution method using household current is to remove the insulation from the end of an extension cord, plug in the extension cord, and grasp the two bare wires, one in each hand. Alternatively, one can hold one wire and touch a grounded item (for example, an exposed metal pipe) to complete the circuit. This requires the black (hot) wire to be held—if a polarized plug is used and the wiring has been installed correctly. Or, if the circuit/outlet has an on/off switch, one can wrap the bare ends of the extension cord around two different limbs (no chance of letting go) and flip the switch. For example, q60

A few weeks after his wife had been accidentally electrocuted in her bath, a man, aged fifty-eight, was found dead in his locked bathroom. He was seated on a chair; his feet were bare and in a bowl of water on the floor [probably unnecessary]. His wrists were wired to the domestic supply. He had . . . burns around each wrist. He had threatened suicide and left a "suicide note." It appeared that he had felt himself responsible for the faulty condition of the heater which had caused his wife's death. 61

There are many other ways to do this, limited only by your imagination. But don't leave an electrically live (albeit biologically dead) corpse for someone to blunder onto; to avoid this, you could incorporate a timer into the circuit. You should also leave a prominent sign telling people not to touch anything before turning off main fuse or circuit breaker. It might seem that this sort of electrocution would be an option for a terminally ill person in a hospital. However, if the circuit is protected by a "ground fault circuit interruptor," as it should be, this will not work. In adr

282 • Geo Stone dition, resuscitation equipment is generally nearby, making electrocution more difficult. 3. Dropping a 120 volt electric appliance into a bathtub containing water (and you) should do the job, especially if you're also touching metal, for example, a spigot or drain. Even if the device is turned off, the terminal of its attached electric cord is still "live." Estimate of the current involved: 120volts/l,000 ohms equals 0.12 amps (120 mA), which is not enough to trip a standard fuse or circuit breaker; however, you should try it first with an unoccupied tub. Once again, if the device is plugged into a circuit with a G F C I , this will not work; but obviously, one could plug into a non-GFCI circuit. Of forty-eight cases of bathtub electrocution studied, nineteen were judged suicides (three females to one male ratio); electrical marks were seen in eight. The calculated amperage was 100 to 250 milliamps, which is in the ventricular fibrillation range. Fourteen also showed evidence of drowning. 62

EMERGENCY TREATMENT OF ELECTRICAL INJURIES

1. Safely switch off electric power if victim is still attached to current source. If it is necessary to disconnect someone from an electric circuit and you can't turn off the power at a switch or (better) circuitbreaker/fuse box, a bare, dry, wooden pole (power company uses fiberglass, which is less conductive) can be used to push the wire away from the victim. However, while this is generally safe with household wiring, fallen power lines may be "springy" or coiled, and thus dangerous to move, and high voltage (if it's a high-voltage line) can more easily be conducted by dirty or damp wood than can lower voltage. 2. Call for help. 3. If victim is not breathing and/or has no heartbeat, administer C P R as soon as possible, and for as long as death is not certain. There are cases of recovery after as long as six hours of apparently fruitless resuscitation. Success is most likely if C P R is started within a minute of cardiac or respiratory stoppage. Prolonged (more than about five minutes) heart or respiratory stoppage will generally cause permanent brain damage or death due to lack of oxygen to the brain and 63

SUMMARY

High-voltage electrocution is a gruesome and traumatic method of suicide, but it is quick and usually lethal. While it might be considered when a lengthy uninterrupted time cannot be assured, there seems little advantage to it compared to other methods. Unconsciousness is quick, but injuries in survivors are often severe and may be permanent. Low-voltage (household) electrocution is neither quick nor painless, but is also fairly lethal. It is not a recommended choice for either suicide or a suicidal gesture.

How DANGEROUS ARE SUICIDAL GUNSHOT WOUNDS?

Tables 16.1 through 16.4 show guns to be the most lethal common means of attempting suicide: The fatality rate in Card's study was 92 percent, though the actual rate is undoubtedly somewhat lower, since minor injuries are less likely to be reported than fatal ones. The lack of minor injury results further suggests that it's not your best bet for a suicidal gesture. But you probably already knew that. One can reach the same conclusion by noting that guns accounted for 34 percent (1974 data; up to 60 percent by the 1990s) of Card's suicide fatalities but only 1.4 percent of nonfatal injuries. While this study is old, it is in agreement with more recent data from the United States and Finland. Washington State hospital and death certificate data from 1989 to 1995 show an 89 percent fatality rate from gunshot suicide attempts. This was the same as the rate in Finland, where 1,205 of 1,356 gunshot suicides were fatal. Eighty-one percent of these people (1,101 in 1,356) died before getting to a hospital. For people still alive when they reached the hospital, American data show a 76 percent fatality rate from gunshot suicide attempts. The corresponding Canadian death rate was 79 percent. 14

DEMOGRAPHICS: W H O AND WHY? AVAILABILITY OF GUNS

More Americans commit suicide by gunshot than by all other methods combined. Roughly 18,000 of some 30,000 suicides a year in the United States (7.6 per 100,000) are by means of firearms. It should be no surprise that the high rate of American firearm suicides is a function of the widespread availability of guns in this country: 45 to 70 percent of Americans have them in their homes (up to 90 percent in parts of the West). In areas of the world where guns are hard to obtain, people tend to use other methods. For example, firearms are used by less than 5 percent of 8

9

b10

Suicide and Attempted Suicide • 287 11

male suicides in England and Wales, and by almost no women, probably because handguns are severely restricted. Shotguns, on the other hand, are commonly used in hunting, and shotgun suicides are more frequent than those by means of handguns. In India, where factory-made guns are relatively expensive and many people work on farms, poisoning by pesticides is the most common suicide method. c

d12

On the other hand there are obviously important factors other than gun availability that affect firearm suicide rates. For instance, Australia, as well as Great Britain, has strict handgun (but not long gun) control laws. Yet the Australian gun-suicide rate is around ten times that of England and Wales, while its overall suicide rate is twice that of England and Wales. 13

14

In parts of the world where civilian handguns are difficult to acquire, a much larger percentage of men than women shoot themselves. Thus, in Sweden, 16 percent (2,203) of male suicides but only 1 percent (55) of female suicides between 1973 and 1984 were by guns. This is probably because most of the available firearms are either military or hunting weapons, which are generally more accessible to and commonly used by men. Because of size, men also could be expected to find long guns somewhat easier to use than women would. For example, of 1,200 gunshot suicides in the Dallas area, the ratio of male-to-female handgun users was 3.66 to 1 (703 to 192); with long guns the ratio was 12.26 to 1 (282 to 23). In the United States more than one-third of female suicides are by gunshot, while about two-thirds of the men who kill themselves use guns. Again, there are other factors at work, as shown by the fact that in Canada, with a national suicide rate similar to that of the United States, only about 2 percent of female suicides were by gunshot, both before and after guncontrol legislation. 15

16

17

SUBSTITUTION OF METHODS

Whether restricting gun availability decreases the suicide rate or merely causes people to use other methods is in dispute. Overall, the evidence seems to favor the switch-to-other-methods position. For example, the Seattle and Vancouver metropolitan areas are similar—almost identical—in most socioeconomic aspects, such as income, education, and population. They differ on gun control: Guns are easily available in Seattle; handguns 18

288 • G e o Stone

are essentially banned in Vancouver (and the rest of Canada). Not surprisingly, the handgun suicide rate in Seattle was 5.7 times higher than that in Vancouver. However, the overall suicide rates were the same (15.1 in 100,00 in Seattle, 15.5 in Vancouver), because Vancouver had about 1.5 times Seattle's rate for other methods. On the other hand, among those in their teens and early twenties, the Seattle handgun suicide rate was 9.6 times higher than the Vancouver rate, and this was not entirely offset by the higher Vancouver nonhandgun rate. 19

Certainly there are countries that have low rates of gun ownership along with low (Great Britain, 8.8 in 100,000 per year), medium (Japan, 17.6), or high (Denmark, 31.6) suicide rates; others have high gun ownership along with low (Israel, 6.0), medium (United States, 11.8), or high (Switzerland, 25.7) suicide rates. Obviously there's much more to suicide rates than mere gun ownership. Just what that "more" might be remains controversial, but generates lots of journal articles and books. In any case, fewer than 10 percent of gunshot suicides buy a gun for that purpose. Even fewer buy one shortly before killing themselves. Thus, a "waiting period" to buy guns will have little effect on suicides. On the other hand, when someone makes an impulsive suicide attempt with a gun, the results tend to be a lot more lethal than had she taken a handful of random pills. A n d young people tend to be most impulsive. A c cording to former Surgeon General Everett C. Koop, almost all of the increase in the adolescent suicide rate is by means of firearms. One thing that is clear is that the suicide rate is significantly higher in homes that contain guns than in homes that don't. To put this risk into perspective, some (there are many others ) variables associated with increased suicide risk are shown in Table 22.1 below. Note that "associated with" does not necessarily mean "caused by." For example, not graduating from high school probably doesn't cause many people to kill themselves. But it's also statistically associated with lower economic and social status, more beer drinking, fewer symphony visits, more likely ownership of American cars, more cigarette consumption, and so on—some part or combination of which does increase chances of suicide. Table 22.1 shows the "adjusted odds ratio," which is a statistical measure of how much more (or less) likely suicide is for someone with a particular characteristic, 20

Suicide and Attempted Suicide • 289 such as alcoholism, compared to a "similar" person without the trait. An odds ratio of 2.5 makes the claim that a person with the attribute is 2.5 times as likely to kill himself than one without it; 0.5 is half as likely.

Thus, keeping guns in the house is associated with slightly higher odds of committing suicide than not having graduated from high school and slightly lower than living alone. Looking on the bright side, the availability of a gun in the home decreases the odds of committing suicide by other methods. W i t h regard specifically to adolescents, the presence of any firearm in the home was associated with a doubled suicide rate. There were no distinctions between types of stored weapons or methods of storage; storing guns locked or separate from ammunition didn't make much difference. But, lest guncontrol advocates get too optimistic about the benefits of restricting handguns, (a) almost half of adolescent gun suicides used long guns, and (b) those 24

with access only to long guns killed themselves at the same elevated rate as those with handgun access. U.S. firearm-suicide data are shown below in Table 22.2. As with most suicide methods, the highest death rates are associated with older white males. 25

Between 1953 and 1988 the U.S. suicide rate by firearms increased from 4.9 per 100,000 to 7.4 per 100,000, while other methods remained stable. Many observers have suggested that this increase is due to the parallel increase in the number of guns owned by Americans. However, while the number of guns per person has risen, the percentage of gun-owners has not; that is, the same (or a slightly lower) percentage of Americans own more guns. Thus the increase in the number of guns is not, in itself, a plausible cause for the increased gun-suicide rate. On the other hand, the percentage of handguns has gone up (rifles the same, shotguns fewer), and handguns are used at a disproportionately high rate in gun suicides. Thus the increase in the gun-suicide rate (but not the overall suicide rate) is correlated with the higher availability of handguns, rather than guns in general. 26

Suicide and Attempted Suicide • 291 There have been numerous other theories as to the reason(s) for the i n crease in gun suicides. One frequently cited notion is that television and movies unrealistically portray life as perpetually exciting and shootings as quick, clean, neat, and painless. While parents spend an average of two minutes a day communicating with their child, the television spends an average of three and a half hours a day with their child. The average child will watch more TV by the time he is six than he will spend talking to his father for the rest of his life.... By the time he graduates from high school, he will have logged twenty thousand hours in front of theTV, compared to eleven thousand in the classroom... ."TV bombards kids with the glamorous and the thrilling, and then they have to go out and live their lives, and their lives are not glamorous and thrilling," says high school counselor George Cohen. "TV doesn't help kids understand that life on a day-to-day level can be boring and mundane and upsetting. Being held up to that image when you have to face the realities of your life can be discouraging, if not depressing." And on TV no problem is so great that it can't be solved in half an hour 30

In addition, the TV actors who are killed in one show turn up alive on another show, increasing the unreality of killing. It is interesting that young women, who as a group tend to use nondisfiguring methods/increased their gunshot-suicide rate by 50 percent between 1970 and 1980. This rise continued for 10- 14-year-old girls (but not other young women), going from 18 (0.20 per 100,000) in 1980 to 47 (0.50 per 100,000) by 1995. Similarly, in one study the ratio of women-to-men in psychiatric referrals for (survivors of) self-inflicted gunshot wounds more than doubled, rising from one in seven to one in three between 1977 and 1987. Over the same time period, the percentage of women in this study who had owned a gun for more than a year went up by over 50 percent, suggesting, plausibly enough, that increased availability of and familiarity with guns tends to increase their use. 31

32

Also consistent with this are epidemiologic studies which claim that states with stronger gun-control laws have a lower rate of firearm suicides. However, data from Canada and elsewhere show that the decrease in firearm sui33

292 • G e o Stone

cides in these places was approximately equalled by an increase in other methods, particularly jumping. For example, between 1973 and 1977 there were 117 suicides by gunshot and 80 by jumping among Canadian males. Between 1979 and 1983, after national gun-control legislation, there were 80 gunshot and 111 jumping suicides. But, as noted earlier, Canadians and Americans may differ in relevant ways. 34

Perhaps one reason that these studies come up with differing results is that the net is too big: It includes all motivations, whether they involve impulsive or resolute behavior, terminal or mental illness, alcoholism or whatnot. It may well be that some impulsive people will kill themselves if a gun is handy, but not otherwise. It may also be that a terminally ill person or prisoner will readily substitute any reliable method. For example, the suicide rate among judicial and psychiatric prisoners is several times that of age-matched nonprisoners, despite staff surveillance and lack of availability of most lethal methods. 35

WHAT PORTION OF GUNSHOT DEATHS ARE SUICIDES? U.S. data from 1988 show 18,181 (54.2 percent) suicidal, 13,666 (40.7 percent) homicidal, and 1,694 (5.1 percent) accidental deaths caused by firearms (and explosives). Numbers from 1987 and 1989 were almost identical for suicide, but increased from 12,657 (1987) to 14,464 (1989) for homicides. By 1994 there were 18,765 (49.8 percent) suicides, 17,532 (46.6 percent) homicides, and 1,356 (3.6 percent) accidental firearm deaths. COST

Estimated costs for a fatal gunshot suicide are $21,700 in medical expenses and $848,000 in lost productivity. For a survived attempt, average medical expenses were $28,000, lost productivity totaled $42,600 (1992 dollars). These figures do not take into account pain, suffering, and lost quality-of-life. 36

FIREARM INJURIES: SUICIDE, HOMICIDE, OR ACCIDENT? A twenty-four-year-old woman was found in her bedroom wedged between her bed and dresser. On the bed were male undershorts smeared with blood. Near the body on the floor was a

Suicide and Attempted Suicide • 293 male shoeprint pointing away from the body. A .38 caliber Colt revolver was in her left hand, the index finger on the trigger guard. A near-contact gunshot wound was present on the right cheek On the palmar surface of the hand, just below the index finger; were two parallel, 1/4-inch-long pinch marks surrounded by faint-brownish discoloration due to gunsmoke. The fired cartridge in the cylinder of the revolver was at six o'clock. The weapon was clean, apparently freshly oiled. The boyfriend, a gun collector; free on probation, was seen driving away from the house after a shot was heard, and he was not apprehended until late that night. He stated that they had had an argument following which she shot herself. He took the weapon from the pool of blood on the floor and wiped the blood on a pair of shorts. W h e n it occurred to him that possession of the gun might incriminate him in a murder charge, he cleaned and oiled the weapon, then placed it back into her hand, [italics added] His statement sounded credible. W h e n the cocked gun was held in the right hand with the thumb pulling the trigger and the muzzle pointing toward one's own cheek and the left hand was placed over the cylinder to steady the weapon, the downing hammer inflicted a pinch of the same appearance and in the same location as on the left hand of the deceased. 37

Score one for good forensic investigation. When a gunshot victim is found, what kinds of things do the police and medical examiners consider in determining whether it was a suicide, homicide, or accident? PSYCHOLOGICAL AUTOPSY. If the situation is murky, frequently they carry out a "psychological autopsy." This includes talking to friends and neighbors, checking medical and psychiatric records, and attempting to determine the state of mind of the deceased. PREPARATION. A suicide note is strong evidence of intent, but only around one in five suicides write them, and a forged note, or one written under duress, is always a remote possibility. There is sometimes evidence of preparation, as in the case of a man who

294 • Geo Stone put the butt of his gun in the stove grate, lit a fire, and sat down in front of the barrel to wait. PROXIMITY OF WEAPON. In suicide, the weapon is almost always at the scene and near the body. There are exceptions, however. Occasionally a fatally wounded person can walk a substantial distance before collapsing, but the trail of blood can be followed back to the place where the injury occurred. A handgun is sometimes thrown some distance by the fatally injured suicide, for no known reason. More frequently, the weapon is removed by a friend or relative who wants to avoid a verdict of suicide, often for either financial (many life insurance policies will not pay, in case of suicide, unless the policy is more than two years old) or social ("What will the neighbors think?") reasons. INSTANTANEOUS RIGOR. In rare cases, there may be "instantaneous rigor" (a.k.a. "cadaverous spasm"), where the hand firmly holds on to whatever it was grasping at the time of death. Removing a loaded semi-automatic pistol in such a situation is something of a challenge. Instantaneous rigor, though of unknown cause (and even disputed existence), is considered conclusive evidence of suicide, since placing a weapon into a dead person's hand does not achieve the same effect and there's no known—or at least published—way to simulate it. CONTACT WOUND. A contact, or near-contact, wound is one where the muzzle of the weapon was touching, or almost touching, the victim when fired. Evidence for such proximity may include gunpowder residues on the hand and the wound, singed hair near the wound, blood in the gun barrel, the cherry-red color characteristic of carbon monoxide (caused by the incomplete burning of the gunpowder) in blood or tissue, and sometimes massive tissue damage from the expansion of hot gases at the muzzle. These gases, sometimes combined with the forceful ejection of wadding, is how people have been killed by "blanks." There may on rare occasions be a muzzleshaped abrasion around the entrance wound, caused by the impact between gun barrel and skin.

Occasionally (most often with rifles and shotguns, rather than handguns), the muzzle is held in place with one hand while the other hand pulls the trigger; this can cause a contact wound to the hand rather than to the fatal site. Overlooking the hand wound might lead an investigator to think that

Suicide and Attempted Suicide • 295 the bullet had been fired from further away, mistakenly suggesting murder. While a contact wound doesn't eliminate the possibility of murder, a distant wound, in the absence of clear evidence to the contrary (for example, a gun held in a vise and fired with a long stick), does eliminate a verdict of suicide. FINGERPRINTS. If the only fingerprints on the gun are the victim's, it is, obviously, consistent with suicide. However, murderers have been known to wipe off a gun and place it in their victim's hand in an effort to disguise the crime. There has even been a case where a murder defendant claimed that his fingerprints on the gun were due to his attempt to prevent the suicide. INDIRECT TRIGGERING. When a long-barreled weapon is used, often a stick, rod, string, or other means of pulling the trigger is found at the scene. In their absence, the victim's arms are measured to estimate the likelihood of his being able to reach the trigger. If the suicide is barefoot, the possibility that he used a toe to push the trigger has to be considered. 38

WHAT CAN THE SITE OF THE WOUND TELL US?

The distribution of fatal wound sites can be informative. In a study of 175 self-inflicted lethal gunshot wounds to the head or neck: • Most of the self-inflicted gunshot wounds to the forehead are right on the midline. • Fatal neck wounds were all in the front. • There were no wound sites behind and under the ear: Such a wound, especially one under the left ear for a righ-handed person (or vice versa) is very likely—but not certainly—murder. It's commonly thought that when people shoot themselves in the head, they pick the side that is the same as their handedness. Indeed, Seattle investigators found that all five of the left-handed people who shot themselves in the side of the head picked the left side of the head—but so did five (9 percent) of fifty-five right-handed people. Similarly, data from Dallas showed that 7 of 141 (5 percent) suicidal shots to the head were to the left temple by right-handed people. This suggests that there should be only a minimal suspicion of foul play in what would otherwise be unquestionably a suicide if 39

296 • Geo Stone the "wrong" side of the head was injured. On the other hand, a fatal handgun wound to the abdomen, eye, or back of the head is more suspect because of its rarity in suicide. In suicidal wounds through the mouth, the mouth is generally open and the tongue depressed when the shot is fired. If there's damage to teeth and tongue, it's probably homicide. However, the absence of such damage does not necessarily mean suicide, since occasionally a murder victim has been forced to open his mouth or is in the process of screaming or shouting when shot. I have not had a fall. I was writing a letter to Mrs. Anderson and a pistol went off under my ear — M r s . Bertha Merrett (Murphy 1985) The site of the wound may be an important issue in a trial, as in the case of J. D. Merrett in 1927. He was accused of the murder of his mother by shooting her with an automatic pistol; his defence was that she had shot herself.The wound was situated at the back of the right ear, immediately behind [the ear]; the bullet had passed forwards to the base of the skull and lodged ... without causing injury to the brain; she died, about a fortnight later, from meningitis. The site of the wound is unusual for suicide but Sir Bernard Spilsbury [the most eminent forensic pathologist of the time], who gave evidence for the defence, believed that this site and the direction of aim were not inconsistent with suicide. He instanced a similar case of his own in which the victim was found with the weapon firmly grasped in his hand ["cadaverous spasm"]; death had been instantaneous and there was no doubt that the circumstances were then those of suicide. In the Merrett case, a verdict of " N o t g

Proven" was due, in the main, to the fact that the medical witnesses were unable to agree.

40

D u e to the serendipitous nature of research, I ran across further references to this case while looking into something else. To make a long story short, Spilsbury made an inexcusable mistake, because he had carried out his tests

Suicide and Attempted Suicide • 297 using a different gun and powder. Merrett went on to a life of crime, and eventually brutally murdered his ex-wife and mother-in-law for money. Having been seen by neighbors, and realizing that the police were closing in, he fatally shot himself in the head. 41

CAN A GUNSHOT SUICIDE FIRE OFF MORE THAN ONE ROUND?

Multiple gunshot wounds understandably raise suspicion of foul play, but they also occasionally occur in suicides. There were fifty-eight multiple-shot suicides, or 1.6 percent of all firearm suicides in North Carolina from 1972 to 1978. The distribution (mostly middle-aged white males) by age, race, and sex was somewhat different from single-shot suicides (mostly older white males) in the state and nation. A majority of these shot themselves at home. Only 15 percent had alcohol (quantity unspecified) in their bodies, substantially fewer than the approximately 40 percent of the total gunshot suicide group who had been drinking before killing themselves. One might speculate that absence of alcohol improves the eye-hand coordination needed for a second shot. This, however, might be a hard hypothesis to test. In Seattle there were three of 223 (1.6 percent) suicides by multiple—in this case two—gunshot wounds, consistent with the data from North Carolina indicating that the existence of such wounds does not necessarily imply murder. The Chief Medical Examiner in North Carolina also mentions multiple suicidal wounds in a warning against the mistaken prosecution of an innocent "perpetrator." (There is more detail on multishot suicide later in this chapter.) 42

43

Multiple injuries have been occasionally described in the medical literature. In one case, four gunshot wounds were found in a suicide. Two, presumably the first two, were flesh wounds to the head; the latter two were fatal shots to the heart. In another instance a man shot himself in the neck with a shotgun, suffering severe damage. He then walked back to where his ammunition was, reloaded, returned to the scene of the first shot, and shot himself in the head, this time fatally. There are even cases of multiple suicidal shots to the brain. One man shot himself upward through the mouth, injuring an optic nerve and tern44

298 • Geo Stone poral lobe (front) of the brain. He then drove home and shot himself in the temple. He lived two days. Another man shot also shot himself through the mouth, but aimed too low and a bit off to the side, slightly damaging his spine. His second shot was through the right temple and injured the temporal lobe. A third shot, through the left temple, was fatal. In both of these cases low-energy ammunition (.25 and .22 caliber respectively) were used. The record for this sort of thing seems to be held by a young man who killed his lover and then shot himself in the head seven times before giving it up as a bad business and hanging himself. 46

RESULTS: HOW AND WHY ARE GUNSHOT WOUNDS FATAL?

Obviously, gunshots can cause severe tissue and organ damage. Death, when it occurs, usually results from loss of blood leading to irreversible shock, or from injury to a vital organ(s), such as the brain or heart. BLOOD LOSS. Injury to a large artery or vein can cause death within minutes. Such vessels are to be found in every major region of the body. Some wellknown vessels include the carotid artery and jugular vein (in the neck and head), aorta, pulmonary and thoracic artery (chest), hepatic (liver), femoral (thigh/groin), and brachial (shoulder). The mechanism of shock from blood-loss is interesting. An adult normally has about five liters (5.3 quarts) of blood. If you were to lose one liter (about twice what you give as a blood donor) what would happen? Nothing much; your body is very good at compensating—up to a point. The drop in blood pressure due to blood loss increases the heart rate from the normal 70 as high as 200 beats per minute. Tiny arteries and veins constrict, especially in the limbs, making more blood available to the major vessels and organs. This raises blood pressure, and everything is okay, other than having cold hands and feet.

However, if blood loss is great enough (more than about two liters), there is progressive and eventually irreversible deterioration. Because there isn't enough blood left, the heart muscle doesn't get adequate oxygen and nutrients, and beats more weakly. Because the cardiac output thus decreases, less

Suicide and Attempted Suicide • 299 blood gets to the lungs to pick up new oxygen. The lack of oxygen weakens the heart muscle further, a downward spiral that ends in death. (Things are actually a good deal more complicated, but this gives the basic picture.) If blood is replaced soon enough, the process can be reversed, but if delayed, even adequate transfusion will only postpone death for an hour or two, since the heart muscle has been irreversibly damaged. A contact shotgun blast to the temple or cheek causes damage from the shot, the wadding, and the propellant's hot gases. The skull may burst and pieces of scalp, bone, and brain be scattered over several feet. Eyes may be blown out of their sockets. Damage may be so severe that i n experienced medical examiners have been known attribute suicide by shotgun to an axe murder. HEAD INJURY.

47

A shot upward through the mouth is less likely to produce an exit wound, since the hard palate absorbs some energy and decreases the residual force of the explosion. The nose, sinuses, and nearby blood vessels are demolished. W h i c h part of the brain receives the brunt of the damage depends on the position of the barrel when the trigger is pulled. The skull is often cracked, but sometimes the more elastic scalp remains intact. High-powered rifles cause similar injuries if the bullet shatters, mushrooms, or tumbles, which is usually the case when it hits bone. Occasionally, survivable injuries are produced by a bullet that exits intact and undeformed, but this should not be relied on. Low-powered rifles and handguns generate a few nonlethal head injuries, most often when the low-energy bullet is fired at an oblique angle to the skull and is deflected. On the other hand, such a bullet that enters the skull will generally fragment, tearing multiple tracks through brain tissue—and is very unlikely to have enough energy to make an exit hole. CHEST AND ABDOMEN INJURY. If a bullet injures the heart, death is usually swift. This is because either the heart muscle is too damaged to pump blood or the major blood vessels near it are destroyed. The results are the same: hemorrhage, shock, and death. Wounds elsewhere in the chest and abdomen may or may not be survivable, often depending on whether a major artery or vein is severed, and the availability of quick medical help. Less common injury can also occur. For example, bullets or their fragments and shotgun pellets occasionally lodge in an artery or vein, causing an

300 • Geo Stone embolism (blockage), with sometimes fatal results. In one case a man shot himself in the chest and the bullet entered the lower right heart chamber (right ventricle). It eventually migrated to the main artery of the lung (right pulmonary artery) where it caused massive lung damage (infarction) due to interruption of the lung's blood supply. The victim survived nineteen days. In another unusual case, a woman died of lead poisoning after several years of carrying a bullet lodged in her knee. While rare, there have been similar cases, both fatal and nonfatal. 48

49

50

Another uncommon, but well-documented, source of gunshot injury is the hot and expanding gases that enter a contact-wound site along with the bullet or shot. In two cases a shotgun contact blast to the temple injected enough high-pressure gas that it blew a half-dollar-sized hole through the front of the skull, directly between and slightly above the eyes. The initial wound was one that would be instantly lethal, so the existence of what appeared to be a second site (in a suicide) was at first perplexing. Autopsy resolved the issue. 51

There is even an instance of a man who was killed by a shotgun blast even though none of the pellets or wadding hit him. The shot had passed between his chest and left arm. He suffered broken ribs, lacerations of left chest, inner arm, and lung, and massive bleeding in his chest cavity—the last being the fatal wound; death was from blast injury due to expanding gases. 52

SURVIVAL TIME AND MOBILITY AFTER INJURY Death does not occur instantly except under a few circumstances. Death obviously does not occur in the way many television programs would have us believe. 53

In most cases of fatal (nonfatal wounds will be discussed in the next section) gunshot wounds to the head or heart, collapse is rapid but death may not be. In one study of fatal brain gunshots, 98 percent of victims found alive maintained vital functions (heartbeat, blood pressure, breathing) long enough to reach a hospital and be evaluated. 54

In one case a Finnish man committed pistolshot-to-the-head suicide—in front of a movie camera he had set up. There was immediate collapse, but

Suicide and Attempted Suicide • 301 just before the four-minute film ran out, he opened his eyes and raised his head; how long he survived and his capabilities before dying are unknown. Specific regions of the brain control particular functions. For example, the brain stem, at the base of the skull, is responsible for maintaining, among other things, breathing, while the cerebral cortex, just behind the forehead, is the seat of intellectual abilities. Thus, someone with a wound that is limited to the cerebral cortex may well remain mobile (and sometimes even coherent) for minutes or hours. Similarly, a bullet that travels from temple to temple may miss the brain entirely, passing beneath it, possibly cutting the optic nerves and causing blindness, without producing immediate collapse. On the other hand, a shot to the brain stem is quickly fatal. "One-shot" targets are those where a bullet wound is instantaneously i n capacitating and quickly fatal. These are: brain stem, basal ganglia, medulla oblongata, and spinal column in the neck. "Rapidly fatal" targets allow ten to fifteen seconds of voluntary action after a gunshot wound. These are the heart and the large blood vessel above it, the aorta. Injury to other organs, though often lethal, allows more time before incapacitation. A gunshot to the front of the head may fall into any of these categories, depending on the bullet's angle and how far it penetrates. Large caliber and high-velocity bullets are most likely to be immediately disabling, but there are no guarantees. The ability to function despite soon-to-be-fatal brain injury is remarkable: 55

An elderly man left his hotel one evening and did not return that night. This occasioned no comment because he was accustomed to absent himself without notice. He returned at 7:30 A . M . and when seen by the maid at the door; he had his umbrella over his arm and his hat on his head. The maid, however; noticed bloodstains on his face and called her mistress.The man placed his umbrella in the hall, took off his overcoat and then, saying "I will just go upstairs," did so. He was found unconscious in the bathroom and transferred to hospital, where he died three hours later He had a bullet wound of entry at a point beneath the chin two inches to the left of the middle line.... The bullet had traversed the base

of the tongue, the frontal and temporal lobes of the brain, which were extensively damaged, and had left the skull at the left side of the frontal bone; the exit wound was that of a .45 [caliber] bullet which had turned on its side inside the skull. A .45 revolver the property of the deceased, was found in some gardens, near the hotel. Investigation of the scene showed that the man must have shot himself before 6:30 A . M . and, for some time, had walked about before he returned to his hotel, when he still appeared to be reasonable and intelligible. 56

A study of such unusual cases found that 70 percent were associated with low-energy ammunition (small and/or slow bullets); most of the remaining bullets were antique or homemade. None involved shotguns or center-fire rifles from close range. There is also a good deal of variability in the outcomes of similar injuries. In one instance of a self-inflicted shotgun wound to the head, the family insisted on no treatment, and none was given. Nevertheless the victim lived forty-five hours. Another person with a similar injury died within five minutes. 57

While data on suicide are meager, about half the people who die of homicidal handgun wounds do so within ten minutes of being shot; another third die within a day. 58

INJURY SITES IN GUN SUICIDES If you wanted to kill yourself with a gun, what part of the body should you aim for? Head or heart give the best (though not 100 percent certain) targets for quick and fatal injury. An abdominal shot is a very poor third, since you are both less likely to die and more likely to take a long time in doing so. Single pistol shots to limbs are generally not fatal, though it's always possible to bleed to death from a severed artery or die of infection. Exactly what parts of the head and body do suicides aim for? First we'll look at fatal wounds; later we'll compare them with nonfatal ones.

304 • Geo Stone From Seattle and Dallas we see that almost three-quarters (71 to 74 percent) of all fatal wounds were shots to the head. The most popular single site was the right temple (39 percent), followed by mouth (9 percent), heart (9 percent), mid-front or forehead (8 percent), and presternal or center of chest (6 percent) areas. The "no site specified" is listed because, in six cases, there was such extensive damage as to prevent identification of the entrance wound. Like I said, messy. Comparing this with the data from Bangkok shows that the distribution of head injuries is roughly similar. However, there are some differences: More Thais shot themselves in a region from behind the temple to the back of the head, while more Americans chose the front of the head. S E X . Seventy-two percent of fatal suicidal gunshot wounds, among Seattle women, were to the head. This 72 percent figure is higher than the numbers cited in most earlier papers. Since head wounds are often disfiguring, the authors of this study suggested, perhaps facetiously, that Seattle women might be less vain than those elsewhere. However, this increasing proportion of fatal suicide shots to the head among women has also been found in Dallas where 69 percent (78 in 113) chose that site, as did 80 percent of men (427 in 537). 62

Most bullets that enter the heart are swiftly fatal, though one lodged in the left ventricle may take a long time (minutes to hours) to kill i f the muscle seals around it. A more common, though still rare, reason some shots aimed at the heart are survived is that the bullet may be deflected a few degrees by the ribs. To avoid this, one can aim under (or between) the left-side ribs, with an upward trajectory toward the right side of the neck. Even if you don't cause fatal heart damage, there's a fair chance that the bullet will hit the aorta (the largest artery in the body), one of its major branches, or the vena cava (the largest vein) with lethal results. Curiously, in many suicidal gunshot (and knife) wounds of the chest, the victim first lifts or removes his shirt, perhaps to bring the muzzle into closer contact with the skin, or out of some final fastidiousness. GUNSHOTS TO THE HEART.

Suicide and Attempted Suicide • 305 NONFATAL GUNSHOT WOUNDS

In the next sections we look at the following questions: • What are the demographic and psychiatric characteristics of suicidal-gunshot survivors? • What are the target sites chosen by these survivors? • What are the medical consequences of their attempts?

CHARACTERISTICS OF SURVIVORS OF SUICIDAL GUNSHOT WOUNDS

SEX AND RACE

In the Lexington, Kentucky, metropolitan area, which is about 80 percent white, 88 percent of 260 gunshot-suicide survivors were white, 12 percent black. Seventy-seven percent of the whites and 67 percent of the blacks were male. This is in line with the fact that, in all age groups, whites have a higher suicide rate than blacks, and males a higher rate than females. Age distribution was generally consistent with nationwide data on completed suicide, peaking in the twenties.Table 22.4 summarizes a number of their characteristics: 65

• The male/female ratio in survived gunshot wounds is higher (3:1) than that for completed gunshot suicides (2:1). This "excess" of male survivors is a bit surprising since, in general, men's suicide attempts tend to be more lethal than women's. However this notion may reflect men's preference for more lethal methods (for example, guns rather than drugs) rather than more lethality within a given method. • Shotguns and rifles accounted for 5 percent of the weapons used by these survivors, compared to 36 percent of weapons chosen by fatally wounded suicides in Seattle. Given that all types of guns are readily available in both areas, it seems reasonable to conclude that, in suicide attempts, shotguns and rifles are more lethal than handguns.

Suicide and Attempted Suicide • 307 • Head wounds were far less common (24 percent of the survivors in Lexington) than in fatal gunshots (74 percent of fatal wounds were to the head in Seattle); abdominal wounds far more common (34 percent versus 4 percent of fatal wounds in Seattle). These data are consistent with the much higher lethality of gunshot wounds to the head than to the abdomen. • Distribution of wounds between head, chest, and abdomen was roughly equal; this is consistent with other data. • Alcohol use was similar to that in completed suicides. 66

What I find most striking about these data is how little premeditation there seemed to be: 80 percent of the suicide attempts were described by the researchers as "impulsive" (regrettably, undefined). A number denied that they had really intended suicide. Two even initially claimed to have been shot by someone else. Equally remarkable is that only 7 percent had made (or admitted to) a previous suicide attempt before trying a highly lethal method, gunshot. Thus, apparently one cannot count on a "warning" attempt prior to a gunshot suicide attempt. The two most common psychiatric diagnoses in this group of 260 people were major depression (40 percent) and continuous alcohol abuse (20 percent). Marriage or relationship difficulties were the most frequent reasons cited for the suicide attempts, but many attempts were by severely depressed individuals with less specific problems. (Or more specific problems: Four shot themselves after killing their spouses.) MEDICAL CONSEQUENCES OF NONFATAL GUNSHOT INJURIES

What are the medical consequences of surviving a self-inflicted gunshot? A gunshot wound, particularly at close range, is often disfiguring or permanently damaging. Since many suicidal people are already seriously depressed and have poor self-image, this is not helpful, and they may become even more withdrawn. On the other hand, at least one study claims that, emotionally, survivors of suicidal head wounds do relatively well after (if) they get out of the hospital. The fact that there is little or no correlation between the severity of a sui67

308 • Geo Stone cide attempt and the likelihood of a subsequent attempt also suggests that coming close to death may be catharic (or may increase family or social support). Nevertheless, this seems like a hazardous way to find out. A n d the physical effects can be catastrophic. Looking again at the 260 Lexington residents who survived self-inflicted gunshots, many were left with permanent injuries: forty people (15 percent) with colostomies, fifteen (6 percent) with brain damage, twelve (5 percent) with repeated seizures; ten (4 percent) with wound infections, and ten (4 percent) needing limb amputations. Since this group included some (presumably less serious) accidents as well as suicide attempts, one might expect that suicidal injuries would be even more devastating than these data indicate. 68

NONFATAL GUNSHOTS TO THE HEAD

Not all gunshot wounds to the head are equally dangerous. Since the "old" or "primitive" parts of the brain are responsible for maintaining and regulating basic functions like breathing and temperature, injury to these areas tends to be quickly fatal. It's not a coincidence that many executions are carried out by a single shot to the base of the skull. This part of the brain is located at the lower back of the head, near where the spinal column meets the skull. Shots into the base of the skull damage this tissue (brainstem), as do shots straight through the mouth from front to back. Shots to the front of the head may cause unexpected problems: The cerebral cortex, directly behind the forehead doesn't control any vital functions, so injury there is not directly life-threatening, but may well result in intellectual and personality deficits. Firing a gun, especially a shotgun or rifle, with the muzzle under the chin or aimed at the face, is somewhat less likely to be fatal than one might expect. Apparently, people tend to flinch or tilt their head back at the moment they pull the trigger, changing the direction of bullet entrance and decreasing the chances of fatal brain damage while increasing that of massive facial injury. This is generally not a problem when the muzzle is in the mouth: Using 12-gauge shotguns in this manner caused the head to burst open in 74 percent of cases; only 9 percent of such wounds with a 20-gauge shotgun resulted in similar injury. Shotgun wounds from a .410 were similar to 20gauge; 16-gauge was in between 12- and 20-gauge in its ability to rupture h

Suicide and Attempted Suicide • 309 heads. A 12-gauge was the most commonly used shotgun (69 percent), followed by 20-gauge (18 percent), .410 caliber (10 percent), and 16-gauge (3 percent). However, rest assured that even a 20-gauge or .410 wound of this sort is quite fatal. There are claims that a low-velocity bullet, like a .22, is more lethal than a high-velocity one, like a .357 magnum, because a low-velocity round will not have enough energy to make an exit wound in the skull, and will thus rattle around in the cranium, turning your brain into something resembling scrambled eggs. There may be some truth to this, since there is little correlation between the caliber of the bullet and the lethality of the resulting head wound. However, with a low-energy (see ammunition section) round there is also the chance that the bullet won't penetrate the skull. In light of this consideration, I think the most reliably lethal combination is a high-energy bullet/shell aimed at the brainstem, either from the back or through the mouth: If that target is hit, it won't matter (to you) that the bullet will also blast an exit hole. 69

OUTCOMES OF NONFATAL GUNSHOT WOUNDS TO THE HEAD

These are some of the most disfiguring of injuries. Quoting from a typical case report: This twenty-year-old man attempted suicide with a 12-gauge shotgun that was placed under his chin and directed to the left side. He sustained a large soft tissue loss [part of his face was blown off], facial nerve injury, loss of vision, and multiple fractures of the mandible [lower jawbone], maxilla [upper jaw], nose, zygoma [cheekbone], and orbit [eye socket]. The patient was treated with tracheostomy [breathing hole in neck], wound debridement [dead tissue removal], and a neck flap. Mandibular reconstruction with a hip graft was complicated by osteomyelitis [bone infection] and a nonunion [bones didn't join]. Two years later he was referred for treatment of a severe facial deformity, facial paralysis, depressed malar eminence [collapsed cheekbone], nonunion, and ankylosis [inability of a joint to function] of the mandible. Inferior rectus entrapment, [eyeball muscle stuck in the wrong place] visual loss, and lacrymal disfunction [inability to produce enough tears to keep the eye moist] were also present. 70

310 • Geo Stone Functionally, there may be permanent damage to vision or hearing, and when the brain is also involved, behavior, speech, and balance may be affected. Seizures and/or tremors are not uncommon. In a study from Houston , of the 48 survivors of gunshot wounds to the head, 32 (67 percent) were eventually considered to be in "good" condition and went home; 14 of 48 (29 percent) were described as "moderately impaired," and 2 of 48 (5 percent) "severely impaired." Nine of these required continued acute care at a hospital and five went to a rehabilitation center. (What happened to the other two is not explained.) This is similar to results from a smaller study in Germany in which about one-third (5 of 16) of survivors needed permanent care. However, less than one-third (13 of 40 or 32 percent) of Phoenix, Arizona, survivors came out in "good" condition. These studies do not include the approximately 70 percent who die before they ever get to the hospital. It's clear that suicidal gun wounds to the head are more lethal than assault or accidental ones, but length of hospitalization is similar in suicidal and assault gunshot wounds. Note also that the survival rate for attempted suicides (22 percent) was only about half that of assault victims (43 percent) in Houston and (30 percent versus 79 percent) in Phoenix. These figures suggest that only about 3 to 9 percent of people with suicidal gunshot wounds to the head will live to get out of the hospital, and that a majority of the survivors will be permanently impaired.

Suicide and Attempted Suicide •311 Looking on the bright side, there is one case that I'm aware of where a gunshot wound to the head was therapeutic. A nineteen-year-old man was so obsessive-compulsive that he spent many hours every day washing himself and cleaning around him. He was unable to continue at school or hold a job, and had no social life. Drug and psychiatric therapy were not effective. His mother threatened to have him committed, and at one point said, "Go and shoot yourself." Five minutes later he did so. He fired a .22 caliber rifle through his mouth and into his brain, but survived the experience. The bullet was found at the base of the left frontal lobe of the cerebral cortex. He had essentially done a self-lobotomy. Upon recovery, his compulsive rituals soon decreased to about fifteen minutes a day, and his obsessions became much milder: He merely insisted on a spotless kitchen and bathroom. Interestingly, his IQ increased significantly, he didn't show the common effects of "therapeutic" lobotomy, and his life much improved. Before you rush out to try this, note that elective psychosurgery by means of bullets does not have a great track record. j

ABDOMINAL

INJURY 78

The previously described study from Lexington looked at 260 survivors of self-inflicted (suicidal and accidental) gunshot wounds. In contrast to fatal wounds which, as we have seen, were largely head injuries, the most common nonfatal site was the abdomen, with 34 percent of the total. C o m bining this piece of information with the 95 percent handgun-use in these survivors and the low incidence of fatal abdominal handgun wounds from Seattle, it seems that abdominal handgun wounds (at least with the weapons used by these people) were not often a successful means of suicide. As an aside, it appears that some authors (and readers) of forensic medicine books may be led a bit astray by their general focus on completed, perhaps to the neglect of attempted, suicide. Thus we read, "Our experience confirms the infrequent choice of an abdominal site by the suicide . . . ", which is true not because the site is infrequently chosen, but because it is infrequendy fatal. However, abdominal bullet wounds are not trivial. Injury to the large or small intestine may involve removal of the affected area. These colostomies and ileostomies require lifetime limits and changes in activities—for example, the use of colostomy bags—which tend to be unpleasant and depress79

3 1 2 • Geo Stone ing. In one study of three hundred consecutive hospital admissions (85 percent male) for penetrating abdominal gunshots, most patients had more than one organ damaged; the average was 2.1 among survivors and 4.0 in those who died. About 10 percent of the survivors had major postoperative complications including hemorrhage, infection, and abscess. Of the colon injuries, 72 percent were repaired, and 26 percent required colostomies. The overall survival rate for all abdominal gunshot wounds was 88 percent—of those who were alive on reaching the hospital. 80

In suicide attempts, one would expect the survival rate to be lower than in accidents because (1) the guns are generally held nearer to the body, permitting more energy to be transferred by the bullet, and (2) the shots are presumably fired with lethal aim and intent; the three hundred wounds in this series include accidents without aim or intent, and assaults with (one would suppose) lethal intent but not necessarily good aim, as well as suicide. On the other hand, in assaults there is more likelihood of multiple shots and wounds. A very rough estimate of survival rate for suicidal abdominal wounds might be 50 percent overall and 75 percent of those getting to the hospital alive. These percentages would tend to be higher when handguns were used and lower for rifles and, especially, shotguns. WOUNDS TO LIMBS AND SHOULDERS

These accounted for 19 percent of all survived wounds in the Lexington study. They can result in permanent, partial, or complete loss of function; occasionally amputation is necessary. In one review of shotgun wounds, three of twenty-two (14 percent) injured limbs had to be amputated. The list below shows the estimate of survival from attempted-suicide gunshot wounds to various body sites from a single round from handgun, rifle, and shotgun. 81

WEAPONS: WHAT TYPE OF GUN SHOULD YOU CHOOSE? The combined effects of the entry of the shot and the products of detonation, i.e., injury by shot and blast, produces gross disruption of the tissues. The scalp and skull may be burst open and parts of the scalp, skull, and brain blown from the body for a distance of several feet. 82

Not all firearms are equally lethal. Lethality depends on several physical factors: (1) Speed of the bullet (we will include shotgun pellets under the term "bullet"); (2) weight of the bullet; (3) type of bullet; (4) size of the gun. In general, the order of most to least lethal weapon in contact wounds is: (1) shotgun, (2) high-velocity rifle, (3) large or high-powered handgun (.45 caliber or .357 magnum), (4) small caliber (.22) rifle, (5) small caliber (.22) handgun. However, there are some exceptions and complications. ENERGY (optional section for math-phobics). Tissue damage is roughly proportional to the amount of energy the bullet transfers to the struck body. Energy, in turn, depends on the velocity and mass of the bullet when it hits. Specifically, Ek=1/2 mv^2 where Ek=kinetic (motion) energy (m=mass, v=velocity, ^2=squared). Thus, a bullet's energy depends more on its speed than its mass: If you double the mass of a bullet, you double its energy; double its velocity and you increase its energy by a factor of four. There are practical limits to this, since the gun barrel must be strengthened to withstand the increased pressure needed to propel a heavier bullet to higher speeds. MASS OF BULLET. Since doubling the mass of the bullet doubles its energy at any given speed, a .45 caliber which has about twice the diameter of a .22 caliber ought to pack four times the energy (volume of a cylinder is proportional to the square of the diameter) if all else (velocity of bullet) were equal. This is one of the reasons that lead is used for bullets: It weighs about 1.5 times as much as does the same volume of steel. Also, since lead is quite soft (you can scratch pure lead with a fingernail), it does minimum mechanical damage to the bore of the gun, though it may clog rifling grooves. "Depleted" (of bomb-grade U-235) uranium is used in armor-piercing artillery shells, partly because it is considerably denser than lead (18.9 gm/ml

314 • Geo Stone vs 11.4), and therefore a given-sized shell packs more energy at the same speed. Besides, you wouldn't want to use soft lead against armor plate. However there are even denser, albeit more expensive, metals. SPEED OF BULLET. The speed of sound is about 1,100 feet (340 meters) per second (fps). The muzzle velocity of high-velocity rifles is around 2,400 to 4,000 fps (730 to 1,200 meters); handguns are mostly 350 to 1,500 fps (100 to 460 meters). Low-velocity (less than the speed of sound) bullets crush or push aside tissue; the wound track is not much wider than the bullet (unless it mushrooms or tumbles). High-velocity bullets are used in military-type rifles and some semi-automatic pistols and have a lead core surrounded by a harder copperalloy jacket. They are designed to not jam automatic loading mechanisms common in military Weapons, and to survive rough field conditions; on striking a body, they are less likely than lead to flatten and more likely to drill a clean hole. Quite sporting. However, if jacketed bullets hit bone or develop a wobble while going through flesh, they can cause extensive damage along the wound track. High-speed bullets send a shock wave of compression ahead of the laceration track. This can tear and even shatter organs, both nearby and, (transmitted through liquid, of which we are mostly composed) distant ones. High-velocity bullets also cause "cavitation." The bullet accelerates tissue radially away from the wound track at a high rate of speed. This generates a temporary cavity that can be much larger then the diameter of the bullet. The resulting near-vacuum also sucks clothing fibers and other sources of infection into the wound. If a bullet exits the body at high speed, it has not transferred maximum destructive energy. Thus, various attempts have been made to prevent the bullet from leaving. Without going into the fine points, these methods include: 1

m

83

• using a hollowed out bullet tip, which tends to mushroom upon hitting tissue, and thus slow down; • using a tip that is softer than the body or jacket of the bullet; • using so-called "dum-dum" bullets with deformed tips, again i n tended to cause mushrooming; • using multiple small bullets, as with a non-rifled shotgun;

Suicide and Attempted Suicide • 315 • using explosive-tipped bullets, which are supposed to detonate on contact. Like mushrooming bullets, they were banned by the Hague Convention of 1899. The direct damage from the explosive tip is relatively small; the major effect is, once again, to distort the bullet, causing more of its energy to be absorbed by, and thus damage, the body. It may be of some interest that John Hinckley shot then-president Ronald Reagan with an explosive-tipped .22 caliber bullet—that failed to explode. OLD AMMUNITION. A n occasional complication in gunshot suicide is the use of old ammunition. Bullets that have been sitting around for years, especially in damp conditions, tend not to reach their rated velocity (and therefore energy) when fired. SIZE OF GUN AND TARGET SITE. The size of the gun is also relevant in choosing a target. This is because a handgun can be easily aimed at almost any part of the body, while rifles and shotguns (typically 40 to 48 inches, or 102 to 122 cm, long) are more difficult to fire into the side and back of the head than into the front of the head or body. 11

Consistent with this is data from fatal suicidal gunshot wounds in Seattle. In head wounds caused by handguns, temple and side injury sites (67 percent) were more than four times as common as frontal (forehead, mouth, and under chin) locations (16 percent). For rifles, frontal sites were slightly more frequent (32 percent versus 28 percent) and with shotguns, considerably more frequent (29 percent versus 17 percent). The side of the head, including temple, was the overwhelming favorite among handgun aficionados (62 percent) but to a much lesser extent rifle (28 percent) and shotgun (17 percent) users. W i t h shotguns, the middle and left part of the chest was preferred, and non-head sites were over 50 percent of the total, compared to 33 percent for rifles and 18 percent for handguns. In addition to the ease-of-aim considerations mentioned previously, I think that the major reason for these differences is that shotguns are simply more lethal than handguns, and thus a larger percentage of people survive handgun wounds to the body. A related possibility is that shotgun users are less discriminating about their target because they are aware that their weapons are highly lethal when fired into just about any essential part of the

316• Geo Stone body. Since the data in these studies were limited to sites of fatal gun wounds, they provide us no is information on this point, or about nonfatal suicide-attempt gun injuries. The Lexington study is more helpful in that regard. Here, the authors looked at 260 people who survived a self-inflicted gunshot wound. The age range was fifteen to eight-one, and averaged thirty-five, for both women and men. Twenty-four percent were women, 76 percent were men. Handguns were used in 95 percent of these nonfatal wounds, compared to 64 percent of fatal wounds in Seattle. This is consistent with the notion that the lower energy of handgun bullets (generally lower muzzle velocity compared with rifles and lower mass compared with shotgun loads) causes less damage than rifles and shotguns. 84

MEDICAL OUTCOME AND TYPE OF FIREARM

It would seem intuitively plausible that higher-energy guns should be more lethal than lower-energy ones. The limited available evidence seems to support this, but not as clearly, or by as large a margin, as one might expect. In Mobile, Alabama, 68 percent (62 of 91) of gunshot suicides used handguns, compared with 80 percent (16 of 20) of survived attempts, where the weapon was known; 13 percent (12 of 91) of suicides (5 percent of survivors) used shotguns; 19 percent (17 of 91) used rifles (15 percent of survivors). This is consistent with shotguns being higher energy weapons than most civilian rifles, which in turn are somewhat higher than most handguns. However there is substantial overlap between the bullet energy of various handguns and rifles. 0

This may be because higher-energy weapons leave fewer victims alive long enough to reach the hospital, but this is speculation. Some other studies have also found little or no difference. What about the condition of the survivors? In the Phoenix study of gunshot wounds to the head, the patient outcome was compared to the type of weapon used. Of one hundred people who were alive when admitted to the hospital, the type of gun was known in fifty-five cases (presumably, mostly suicides), giving the data in Table 22.5. Again, there is no clear correlation between type of weapon and outcome, but the numbers are very small. 86

MULTISHOT SUICIDES TYPE OF GUN USED IN MULTIPLE-SHOT SUICIDE. In the North Carolina data on multiple-shot suicides, .22 caliber handguns were used by half (29 of 58) of this population, reflecting both the popularity of this cheap gun and the low energy of the bullet, which necessitated an occasional second shot. But even much more powerful firearms sometimes needed more than a single shot: One man lived for ten days after two shotgun blasts to the epigastrium (stomach region); another died of a shotgun wound to the epigastrium after first shooting himself in the chest, but at such an angle that the first shot would not have been fatal.

Autopsies were performed on twenty-seven of the fifty-eight bodies. They showed that almost 10 percent of the bullets missed hitting any important organ or blood vessel. Even with fatal injuries, loss of consciousness was not instantaneous except, presumably, in some head wounds. In one case, three .22 caliber bullets hit the victim's heart, two penetrating and one grazing it. Despite this, investigation of the scene showed that he had remained conscious for several minutes. (How this was determined is, regrettably, not described.) Thirty-five of the fifty-eight (60 percent) fired both shots into the same region of the body, but none chose exactly the same spot. The data are shown in Table 22.6. WOUND SITE IN MULTISHOT SUICIDE.

The most popular mixed pair was head/chest, with fourteen of fifty-eight (24 percent), and the head wound was not always the lethal one. Survival of an initial head wound was due to either a failure of the bullet to penetrate

Typically, 60 to 75 percent of fatal gunshot wounds are to the head; in this study of multiple wounds the figure is less than 25 percent, the majority, instead, being to the chest, aiming for the heart. Fifty-four of the fifty-eight (93 percent) suffered two gun wounds; four (7 percent) had three wounds.

SUMMARY

About 60 percent of suicides in the United States are committed with firearms; 76 to 92 percent of suicidal gunshot attempts are fatal. Eighty percent of those who survived acted on impulse, many (25 to 40 percent) while drinking. The chances of living through a self-inflicted gunshot wound depend on many variables: type of weapon, site of injury, availability of medical help, age and physical condition of the shooter. The most lethal site is the head, followed by heart, chest, abdomen, leg, and arm, in that order. Many survivors suffer permanent injury. This is not a recommended method for either suicide or suicidal gesture, primarily because (1) the chances of surviving with permanent injury are too high and (2) it's altogether too easy to pull the trigger on impulse. q

23 HANGING AND STRANGULATION

We must all hang together; or assuredly we shall all hang separately. — B e n Franklin

Hanging and strangulation are effective methods of suicide. Both can be carried out by people with limited physical abilities. Hanging doesn't require complete suspension. Death occurs within about five to ten minutes after cutoff of oxygen or blockage of blood flow to the brain (anoxia); however, convulsions are common and the noise may attract attention. Pain can be minimized by protecting and padding the front of the neck. Since finding the body will probably be traumatic, care should be given to choosing a location. These are highly lethal methods and cannot be done safely as a suicidal gesture. High High, around 80 percent INJURIES IN SURVIVORS: Moderately frequent

LETHAL INTENT: MORTALITY: PERMANENT

PROS AND CONS OF HANGING AS A MEANS OF SUICIDE

Pros: • Quick unconsciousness • Fairly quick death • Easily accomplished with materials found around the house • Can, if necessary, be done without leaving bed Cons: • Possibility of brain damage if interrupted 322

Suicide and Attempted Suicide • 323 • Sometimes a gruesome cadaver, which may be upsetting for whoever discovers the body Suspension hanging is often lumped (and confused) with judicial-type ("drop") hanging, suffocation, strangulation, and even choking. This is entirely understandable, since the subject is confusing, but there are some important, and sometimes critical, differences between them. Brief definitions of these terms may be helpful in making sense of what follows. 1. Suspension hanging: suspension by the neck, with little or no drop. Death is due to compression of the airway (trachea, or windpipe) and/or the major blood vessels connecting the heart and the brain. These latter are the carotid and vertebral arteries, and the jugular vein. We will use "hanging" to mean "suspension hanging" unless otherwise specified. 2. Judicial-type (drop) hanging: a several foot drop, with rope attached to the neck. If everything goes right, death is due to a broken neck. While this is quicker than suspension hanging, it may or may not be less traumatic. 3. Strangulation: manual compression of the airway and/or blood vessels to/from the brain. In suicide, this generally requires a ligature (rope, wire, cloth, etc.). In homicide, there may be a ligature or there may be direct pressure from hands or forearm on the neck. 4. Choking: blockage of the airway by mechanical obstruction, for example, a lump of food. 5. Suffocation or asphyxiation: interference with the ability to take in or use oxygen; related to choking, suspension hanging, and strangulation, in that oxygen is prevented from reaching the brain in each case; however, there is no direct pressure on the airway in suffocation or asphyxiation. Examples are, use of a plastic bag or carbon monoxide (see Asphyxia chapter).

324 • Geo Stone DEMOGRAPHICS: W H O AND HOW MANY? 1

About 4,000 people hang themselves annually in the United States. More than 95 percent of these are suicides. This is similar to the hanging rate in Great Britain, though the overall British suicide rate is about 50 percent lower than in the States. 2

U.S. NATIONAL

STATISTICS

There are roughly 30,000 suicides per year in the United States. The annual average number of suicides by hanging, strangulation, or suffocation between 1979 and 1994 was 4,270. This is about 14.4 percent of official U.S. suicides for those years. Sex, and racial data for U.S. 1994 and 1979 through 1994 are presented below. Rate/100,000

Interestingly, the average (mean) age for suicidal hangings in the United States, is 34.5 years. In Great Britain it's 50.2 (with a peak between 50 and 59) and in Denmark, 53. The reason for these differences is that older people tend to use more lethal methods for suicide attempts. In the United States, that's guns; in Europe, where civilian guns are much less common, it's hanging. Consistent with this notion are data from New York City, where guns are restricted. The N . Y . C . age distribution for hangings was similar to that in Great Britain and Denmark, with a mean age of around 54 years. Since U.S. notional data are not detailed, to find out more about those who hang themselves, we can take a look at some data on age, sex, race, site, and motive on hanging suicides in parts of Seattle (1978 to 1982) and A t lanta (1979 to 1984). The Seattle region surveyed had about twice the population as that in A t lanta (1.26 million versus 0.62 million). The Seattle suicide rate was 14.0 in 100,000; Atlanta averaged 14.6. (The U.S. national rate was around 13 in 100,000.) Hangings were 9.3 percent of suicides in Seattle and 10.7 percent in Atlanta (14.4 percent in U.S., 1982). The population of the Atlanta area covered was 51 percent black, 49 percent white; 53 percent female, 47 percent male. In Seattle, the population was about 80 percent white, 8.5 percent black, and 11.5 percent other (mostly Asian or Native American). 3

The Seattle age range was 14 to 89; average (mean) was 41.3 and median (half above, half below) was 37. A note was found associated with 22 of 61 hangings (36 percent), considerably higher than the 10 to 20 percent of suicides in general. The peak at age 60 to 69 was attributed to people with health problems.

The study from Atlanta was a bit more informative in that it compared hangings with other suicides. Age ranged between 12 and 88 years. Average (mean) age was unspecified and median was 31 years, six years less than for all suicide victims. Notes were found in 10 of 56 cases (18 percent), one as a computer screen display. In Atlanta, black men hanged themselves at twice the rate they used other suicide methods; white women tended to use different means. White men and black women hanged themselves at rates corresponding to their overall suicide frequency. The reason(s) for these differences are unknown, according to the authors of this study. However, as they also point out, 60 percent (9 of 15) of jail hangings were committed by blacks, and twice the percentage of blacks as whites who hanged themselves did so in in jail (38 percent versus 19 percent). Since (a) the Atlanta jail population is disproportionately black; (b) the suicide rate among prisoners in the United States is several times higher than that of the general population; and (c) about 90 percent of prison suicides are by hanging, this could account for some of the unusual hanging data for black men in Atlanta. 15

Fifteen of the total of 56 hangings (28 percent) took place in jails. A n other 24 (43 percent) hanged themselves at home, 5 (9 percent) in woods, 4 (7 percent) in hotels, 3 (5 percent) in health-care facilities, and 5 (9 percent) elsewhere. In looking at the "reasons mentioned," we find that the reasons/motives are roughly similar to those cited for other suicides, except for the disproportionate number of "arrest" (jail) hangings. Alcohol use seems to be less common in hanging than in some other, for example, gunshot or leaping from height, suicides. In one study, only 11 percent showed "legal intoxication." Another report showed 18 percent legally drunk. A third cited alcohol in 34 percent, but included levels well below intoxication. By contrast, between 25 percent and 40 percent of gunshot suicides have legal intoxication levels above 100 mg alcohol/100 ml blood. Possibly, greater manual dexterity is needed to tie knots than to pull a trigger, or it may be harder to work up the courage to shoot than hang yourself without alcohol— somehow it seems more final. Or, as always, perhaps "none of the above." 8

How DANGEROUS IS HANGING COMPARED TO OTHER METHODS OF ATTEMPTED SUICIDE?

Tables 16.1 through 16.4 show that hanging is one of the more lethal methods of attempting suicide, with reported fatality rates of 78 to 88 percent. However, since minor injuries tend to be underreported, the actual fatality rates are lower (but not equally for all methods) than the figures cited. Somewhat more recent (1978 to 1990) data give similar results: Of 306 hangings (92 percent were suicides), 59 percent were found sufficiently dead at the scene that paramedics weren't called; another 19 percent were declared dead at the scene by paramedics; 22 percent were transported alive to hospitals, of whom more than one-third (8 percent of total) died. The overall fatality rate was 86 percent (263 in 306). Almost all the deaths were due to asphyxia, rather than spinal cord or neck injury. 11

PHYSIOLOGY: WHAT IS HANGING, AND HOW DOES IT KILL?

Hanging can kill by four distinct mechanisms: compression of the carotid arteries, compression of the jugular veins, compression of the airway (trachea), and breaking the neck. The first three can result from suspension hanging; the last from drop hanging. O n the right side of your neck, just under the side of the jaw, is your carotid artery. Put your fingers there and gently feel your pulse. It should be quite strong. (If you can't find one, either you're looking in the wrong place or you don't need this book.) The carotid artery carries much of the blood to your brain, which uses around 15 percent of the entire blood supply of your body. Anything which interrupts that blood-flow for more than a few seconds will cause loss of consciousness. JUGULAR VEIN. O n the other side of the neck, under the left side of the jaw is the jugular vein, which carries the "used" blood back to the heart. If the jugular is blocked, blood backs up, much like water in a stream that has been dammed. The carotid and jugular can be compressed with just a few pounds pressure; a moderately tightened rope will do nicely. Death occurs within a few minutes. There does not need to be any pressure on the airway (trachea, or windpipe), though there often is. CAROTID ARTERY.

12

TRACHEA/AIRWAY.

The airway, down the front-center of your neck, can be

328 • Geo Stone blocked internally, (by inhaling a foreign object) or externally (by a ligature). When the interference is internal, it is termed "choking." In either case, obstruction of the airway takes a good deal longer to produce unconsciousness than does carotid pressure, and is much more painful. (Details are in the A s phyxia chapter.) Sometimes choking is the cause of accidental death ("cafe coronary") when a piece of food lodges in the airway and can't be dislodged. So learn the Heimlich maneuver, don't make a pig of yourself when eating, and chew your food thoroughly—your mother was right about some things. "Suffocation" is related to choking, but is an interference with successful breathing, rather than direct blockage of the trachea. Examples include smothering with a pillow or plastic bag and being killed by a boa constrictor. (See the Asphyxia chapter.) Pressure on the neck is sometimes a method of homicide, typically by the use of two thumbs against the airway and the other fingers grasped round the back of the neck. If the neck constriction is due to the body's weight pulling on a ligature, it is called "hanging"; otherwise it is some form of strangulation. This is of some practical significance, since almost all hangings are suicide, accident, or judicial, while most stranglings are homicide. Judicial (drop) hanging is quite a different kettle of worms from suspension hanging. In a (properly done) judicial-type hanging, the victim falls several feet before coming to an abrupt halt at the end of a rope. Often, this is the bitter end. Such a precipitous change in velocity is supposed to cause a broken neck and quick unconsciousness and death. However, exhumation of judicial hanging victims has shown that a broken neck was frequently not the cause of death. An excessively long drop can result in separation of head from body, and is considered bad form by professional hangmen. Suspension hanging can cause compression of the carotid, jugular, and/or airway, depending on how it is carried out. There are similarities between suspension-hanging and choking, as well as the previously mentioned differences. Your blood carries oxygen and nutrients to your brain. Enough pressure on the airway compresses it and prevents oxygen from reaching the lungs. Your body has built-in reflexes to keep this from happening: pressure against your trachea causes quick pain, and you have an irresistible urge to back away and cough; one reflex (pain) HANGING.

13

d

Suicide and Attempted Suicide • 329 gets your attention and moves you away from the stimulus—say, someone's thumbs—and the other reflex (cough) attempts to clear the airway. If these attempts are unsuccessful, blood will continue to be pumped to the brain (and elsewhere) by your heart, but it won't carry enough oxygen and you will lose consciousness in a couple of minutes. TIME TO DEATH. A S asphyxia proceeds, first temporary, then permanent, brain damage from lack of oxygen will occur. Death follows in five to ten minutes (ten to twenty minutes, according to Poison; however, his number seems to be based on the fact that the heart may continue beating for up to twenty minutes after judicial hanging, and ignores that the heart may continue to beat after brain death. While human data are lacking, unanesthetized dogs die after around eight minutes of asphyxia ). On the other hand, it's also true that unconsciousness and death will be delayed i f blood flow to/from the head is only partially obstructed, as is sometimes the case. 14

15

16

Curiously, you don't have the same protective reflexes along the carotid artery, so that pressure sufficient to block the artery doesn't elicit much in the way of defensive reaction. In fact, one of the reflexes that is present may be counterproductive: Near where the carotids divide are some nerve cells, the "carotid sinus." These nerve cells have the normally useful function of maintaining blood pressure at a steady level. They respond to a decrease in blood pressure (for example, when you stand up) by constricting arteries and telling the heart to beat harder. Without this, you might pass out every time you stood up suddenly, because not enough blood was reaching your brain. (The dizziness many people feel when they stand up suddenly is another way of appreciating how quickly and exquisitely sensitive your brain is to absence of enough blood.) Similarly, the carotid sinus responds to an increase in blood pressure by relaxing the arteries and inhibiting the heart. CAROTID

REFLEXES.

So far, so good. The problem arises because these pressure-receptor nerves aren't smart enough to tell the difference between blood pressure and externally applied pressure—for example a forearm or billy club across the rightfront side of the neck. " S L E E P E R " HOLD. Those of you who are wrestling ( T V variety) fans are probably familiar with the sleeper hold; it is nothing more than a forearm pushed against the carotid artery, compressing it, and cutting off blood flow to the 6

330 • Geo Stone 17

brain (see Asphyxia chapter). This causes unconsciousness in about eight to fifteen seconds. The sleeper hold is forbidden in tournament wrestling and is faked in the TV stuff. The reason is that the amount of pressure needed to compress the artery is enough to cause the carotid sinus to kick into overdrive and send the heart a priority message to slow down, which is sometimes enough to stop the heart altogether. Despite being quite aware of this, some police departments continue to use this hold to restrain people they arrest, with the altogether predictable result of infrequent, but entirely unnecessary, deaths. 18

f

19

Another hazard with the sleeper hold is that, during a struggle, the constricting forearm can shift from the side to the front of the neck, compressing the airway and becoming a "choke hold." This requires greater pressure than the sleeper hold, with a corresponding increase in injuries to neck structures, for example, fracture of the thyroid cartilage. More dangerously, the lack of oxygen to the heart muscle can trigger fatal cardiac arrest. In one case, a man's wife sought an involuntary psychiatric commitment order because of his withdrawn behavior and refusal to take medication. The order was granted and two police officers were dispatched to his residence to bring him to the hospital. Coaxing by the police officers proved futile. In an attempt to overcome and handcuff him, one police officer stepped behind the victim and grabbed him about the neck. The hold intended by the officer was the carotid sleeper with the neck of the victim in the crook of the arm and forearm of the officer. After a brief but violent struggle during which both the officer and the victim fell to the floor the victim became lifeless. He did not respond to cardiopulmonary resuscitation. An electrocardiogram taken during resuscitation showed cardiac arrest. Witnesses, including family members, stated that the entire struggle lasted only a short time with the neck hold in place several seconds.... An inquest jury ruled that the death was natural because of the victim's previous cardiac history and the brief time during which the neck hold was applied. 20

Suicide and Attempted Suicide • 331 PRESSURE NEEDED TO COMPRESS THE CAROTID.

HOW

much pressure is needed to

compress the carotid? Surprisingly little. To quote the eminent Doctors Polson and Gee, By experiment I have confirmed that the carotid artery is appreciably obstructed by a ligature under low tension. Having first established free flow of fluid between the common carotid artery, exposed in the upper chest, and the internal carotid artery, seen inside the skull after removal of the calvarium, I then applied a ligature with a running noose round the neck. Weights were added and injection was repeated, below the level of the ligature. The tests showed that a pull of as little as 7 lb (3.2 kg) was sufficient to reduce free flow through the artery to a mere trickle. 21

Obviously, this will vary from person to person, and also with the width of the ligature; other published values are as high as 11 pounds (5 kg). Two problems with these calculations are that, in a living person, (a) the carotids are located deeper in the neck than jugular vein and are shielded by a living sterno-mastoid muscle; (b) blood pressure might open the compressed artery on each heartbeat. More on that in a moment. 22

Since veins operate at lower pressures than do arteries (if you cut an artery, blood spurts out; blood only flows from a severed vein) one might expect the jugular vein to be more easily compressed than the carotid artery. Experimentally, this is exactly the case, with only around 4.5 pounds (2 kg) pressure needed to block the jugular. PRESSURE NEEDED TO COMPRESS THE AIRWAY AND OTHER ARTERIES IN THE NECK. About 33 pounds (15 kg) will compress the airway, and 66 pounds (30 kg) the vertebral arteries leading to the face. PRESSURE NEEDED TO COMPRESS THE JUGULAR.

23

What this means, practically speaking, is that someone who wants—or wants to avoid—a lethal result should be aware that full suspension is quite unnecessary. Death will occur after only a few pounds of pressure on a neck ligature; a sitting or semireclining position is sufficient.

332 • Geo Stone SUSPENSION HANGING

Hanging does not have a very good image. For example: "The discovery of a grotesquely hanging corpse whose swollen, sometimes bitten tongue protrudes from a bloated blue-gray face with hideously bulging eyes is a nightmarish sight upon which only the most hardened can gaze without revulsion." However, while some look livid, about 60 percent of hangers have a "pale and placid" face. Some have small hemorrhages, caused by capillaries leaking (due to high blood pressure in the absence of oxygen), on the face, eyelids, and/or scalp; others don't. 24

25

What accounts for these differences? Basically, it's a question of how quickly and totally the ligature cuts off blood circulation to and from the head. If suspension is fast and complete, the blood supply both to and from the head will be cut off simultaneously, so there is no excess blood or blood pressure in the head, and thus a more or less normal-colored corpse. Similarly, activation of the carotid sinus pressure receptor would cause a decrease in blood flow to the head, leading to paleness in the cadaver. If, on the other hand, the pressure on the neck gradually increased as consciousness was lost, it's probable that the jugular vein was shut off before the carotid artery (and almost certainly before the hard-to-clamp vertebral arteries), since it requires less pressure to do so. Thus, in this case blood would continue flowing into the head while having no way to leave it; hence engorgement and blue/purple color. This is most likely when the suicide is in a sitting or lying position, because there is less (and less sudden) pressure on the neck than when he is completely suspended. PLACEMENT OF THE LIGATURE. A n additional variable is the placement of the ligature. The least pressure corresponds to the location of the knot in the rope, since that point is pulled up and away from the neck. Depending on the knot's site, it is thus possible to miss the jugular (if the knot's on the left), carotid (knot on right), or trachea (knot along the centerline of the face). Further complications arise because the noose can be placed high or low on the neck, with potentially different intermediate results. W h e n high, it is less likely to compress the airway because some of the pressure from the ligature may be transferred to the jaw or skull. DO PEOPLE DIE FROM AIRWAY BLOCKAGE OR FROM CUT-OFF BLOOD CIRCULATION TO THE BRAIN?

Bodies with little weight on the ligature, that is, which are prone or

Suicide and Attempted Suicide • 3 3 3 seated, have a greater chance of death from asphyxia, according to a standard forensic text. Since the jugular vein (blood out) is easier to compress than the carotid artery (blood in), enough blood accumulates in the head and neck to compress the airway, leading to asphyxia. g26

Medical experts disagree about the frequency and importance of airway blockage in hangings. For example, one says, "Occlusion of the air passage by constriction on the neck is probably extremely rare if existing at all." Others hedge their bets: "Suicidal hanging is earmarked characteristically as causing death by compression of the anatomic airway and the blood vessels in the neck." Or cover all the bases: "Reports in the forensic literature have stated that death may be due to either asphyxiation, coma, carotid artery or jugular vein injury, or any combination of the above." Certainly, airway blockage is not essential to successful hanging. In one case a woman with a tracheotomy killed herself despite attaching the ligature above the site of the breathing hole. She would have continued breathing until dying from lack of blood to her brain. 27

28

Airway blockage is more likely when: • the ligature knot is toward the back of the neck. In this situation the maximum pressure from the rope is then on the front of the neck, where the airway is. • the person is seated, semireclining, or prone. Due to little weight on it, the rope tends not to slide up the neck. Were it to move up, it would end up being partially supported by the chin, relieving pressure on the airway. • the ligature is thin or attached with a running noose. Such a ligature tends to clamp in place. • the ligature is placed low on the neck, where it tends not to slide up high enough to be supported by the chin.

WAS IT SUICIDE, HOMICIDE, OR ACCIDENT?

A farmer who, living at a distance from his cattle herd, came to tend the herd alone, [found] the submersible pump in the well which supplied them with water to be broken. He used a piece of

334 • G e o Stone

angle iron as a bridge across the well head, and a peculiarly flimsy and inadequate piece of rope to lower himself into the well to retrieve the pump: the rope broke and he was drowned—or at least this was the story received by telephone from the local coroner W h e n the body was received for autopsy the first finding was a ligature mark around the neck; I telephoned the coroner to point out with some acerbity that this was an obvious suicide. "But Doc," the coroner replied, "that was the only way we could pull him out of the well!" 30

There are four possible definite verdicts in a hanging death: homicide, accident, judicial, or suicide. HOMICIDE

Homicidal hanging is very rare because there are many easier ways to commit murder. Simulating suicidal hanging is generally done to disguise a murder, often an impulsive one. It is also unusual, mostly because it is difficult to pull off without leaving signs of drugging, struggle or improbable i n jury. For example, in a notorious case from Great Britain, Sergeant EmmettDunne killed a fellow soldier, Sergeant Watters, by a karate-chop to the throat and then suspended the body from a staircase to make it look like a suicidal hanging. Autopsy showed an unusual fracture of the cartilage around the thyroid gland and vertical tears in the carotid artery that are typical of drop-type (but not suspension) hangings where there is sudden force applied to the neck. Despite this, a verdict of suicide was rendered by an inexperienced army pathologist due to lack of any other suspicious circumstances. Nevertheless, military gossip persisted about a relationship between E m mett-Dunne and Watters's widow, which was reinforced when, six months later, they married. It was not until a year later that the military police reopened the investigation (as well as the body). Photographs of the original scene showed that blood had pooled both above and below the ligature, in the head, neck, and upper chest regions, which is inconsistent with hanging. There were no tiny hemorrhages, which are often found in cases of asphyxiation.

Suicide and Attempted Suicide • 3 3 5 Under questioning, Emmett-Dunne's half brother (Emmett) came undone and confessed to helping Emmett-Dunne suspend the body. Further circumstantial evidence was discovered, and Emmett-Dunne was convicted of murder and sentenced to life imprisonment. He was saved from hanging because of jurisdictional quirks: He was a citizen of the Irish Republic serving in the British army. The crime had taken place in Germany. The question arose as to where, and under what laws, he should stand trial. Eventually it was decided that there was no authority to send him to England; he was tried, convicted, and sentenced to death by British military court in Dusseldorf in June 1955. However, there was no death penalty in the Federal Republic of Germany (though there was in England at that time), nor, by treaty, could military executions be carried out in German territory. The sentence was commuted to life in prison; he was, however, released after seven years, when passions had cooled. 31

ACCIDENT

How often are hanging deaths due to accident? Combining four studies of hanging , we find that 96 percent (range 94 to 98 percent) were suicidal, and 4 percent (range 2 to 6 percent) accidental. Of the nineteen accidental deaths, five involved children. For the most part, they were toddlers snagged by crib slats and/or their own clothing. The remaining fourteen were all males who had gotten wrapped up in autoerotic asphyxiation. To quote from an unusual review of hanging: 32

A d d sexual perversion to the woes of mankind. W h e n men or women try to improve on nature's biological methods, they not only become frustrated, but worse, act unnaturally, and usually to their own detriment. Any sexual behavior that strays from the confines of normal physiological compatibility is considered to be a perversion. . . . O n e may add to the list another deviation, described by the Marquis de Sade: self-induced asphyxia as a means of ejaculatory gratification in the form of masturbation.... W h e n propelled by concupiscence, the unfortunate person with autoerotic propensities does not suspect that death lurks nearby. 33

336 • Geo Stone It seems that increased sexual gratification can be had by partial interruption of oxygen to the brain. There may also be elements of masochism here. Whatever the motivation, the trick is to make sure the interruption is, and remains, partial. The problem is that unconsciousness can occur without warning; if it does, and if the ligature doesn't slip off or loosen, death follows. These are accidental deaths. The victims are alleged to share some psychological traits with suicides: depression, death fixation, and isolation. However, the circumstances and details of the hangings are usually quite different; in autoerotic hanging:

34

• there are often signs of masturbation; • women's clothing, either worn by the victim or found near him, is common; • erotic literature is frequently found at the site; • there is often a history of successful partial hangings, evidenced by a diary, a collection of ligatures, or wear marks from the rope on the rafter, door, or other attachment point; • typically, the neck is protected by padding; • feet are usually on the floor and/or there is furniture nearby for support; • there are sometimes mirrors or cameras for viewing the (often bound) genitalia; • generally, there is no history of suicidal attempts; • the victims are almost always (more than 99 percent) male, for reasons unknown. 1

These people die because they lose consciousness quickly and unexpectedly. Some of the case reports are truly bizarre. Interestingly, asphyxia as a means of sexual arousal is a centuries-old practice documented by anthropologists. For example, Eskimos (Inuit) apparently choke one another as part of their normal sexual repertoire, and Eskimo children suspend themselves by the neck in play. 35

36

37

Suicide and Attempted Suicide • 3 3 7 The state of unconsciousness is so important and so familiar to the Eskimos that even the children play at it. It is a favorite pastime of theirs to hang themselves by their hoods. When these tighten about their necks, the blood is kept from their heads, and in time they lose consciousness.The other children in the house take them down when their faces turn purple. But they say that the state of unconsciousness is so delightful that they play this game over and over again. 38

The distinction between suicidal and accidental hanging (or other means of death) has legal, as well as emotional, ramifications. Most life (that is, death) insurance policies, understandably enough, have limitation or total exclusion of payments for suicidal death, at least for the first two years. LEGAL CONSEQUENCES.

j

Some pay extra in case of accidental death, for no obvious reason. Is autoerotic hanging an accident or suicide? We must go back to the definition of "accident. "To quote an attorney: The legal definition of accident has not always been the same. Variations have been stated legally in different court decisions. Among these are that an accident is: 1. Any event that take place without the foresight or expectation of the person acted upon or affected thereby; 2. A happening or coming by chance or without design; casual, fortuitous, taking place unexpectedly, unintentionally, or out of the usual course of events; and, 3. Something unforseen, unexpected, or extraordinary. The word, accident, is. derived from the Latin verb, accidere, signifying "fall upon," "befall," "happen," "chance," or "unexpected." In a etymological appraisal, anything that happens can be interpreted as an accident. In its more formal accepted meaning, accident is defined as a fortuitous circumstance, event, or happening. It is an event happening wholly or partly through human agency, an event which, under the circumstances, is unusual and unexpected by the

338 • G e o

Stone

person to whom it happens. An accident is an untoward occurrence in the usual course of events. It may be without known or assignable cause. In its proper use, the term excludes negligence. 39

After all this, it should be no surprise to learn that insurance companies differ as to whether autoerotic hanging qualifies as an "accident," and will examine such a death very closely. So, if you go in for that sort of thing, read your life insurance policy carefully. Should you be in the military, "If the injury or death was incurred as a result of erratic or reckless conduct or other deliberate course of conduct without regard for personal safety, or the safety of others, it was incurred not in the line of duty, but was due to misconduct" then the deceased can expect to be court-martialed for destruction of government property. k

JUDICIAL HANGING My father could dispatch a man in the time it took the prison clock to strike eight—leading him from his cell on the first stroke and having him suspended dead on the rope by the last stroke. That seemed a very worthy intermediate ambition for m e . 40

One hesitates to ask what his ultimate ambition was. Albert Pierrepoint followed in his father's footsteps and became one of the small number of "qualified executioners" in Great Britain. The art of hanging was taught both by apprenticeship and by schooling at some British prisons. There was widespread need for this skill, since as late as 1832, 220 separate crimes, including poaching and picking pockets, were punishable by death. Hangings were public cautionary spectacles and were covered by the newspapers. There are accounts of executioners—sometimes family and friends—pulling on the legs of young boys who were not heavy enough to be successfully hanged in order to add sufficient weight to strangle them. The theory of deterrence by example was in vogue. It was satirized by a contemporary painting of a public hanging in which a pickpocket was working the crowd. As a result of critical newspaper reports of botched hang41

Suicide and Attempted Suicide • 339 ings, the Home Office prepared a standard table of drops in 1888. The formula was basically: 1260 weight of prisoner in pounds

= length of the drop in feet

For example, the calculated drop for a 154 pound person would be 8.2 feet, a bit less than the 9 feet in the drop table shown below. Another source provides similar data: 42

These numbers apply to people of average build with no unusual physical characteristics. The author (James "Hangman" Barry) noted that when executing "persons who had attempted suicide by cutting their throats . . . to prevent reopening the wounds I have reduced the drop by nearly half." This would probably not cause a broken neck, however, and the victim of M r . Barry's aesthetic sensitivities would then be left to strangle, very unpleasantly, over several minutes. Pierrepoint notes, "A master executioner is responsible for every detail of his craft. He has to come to his own decision on the length of the drop based on the Home Office table, varied by his own experience, and adjusted to the

340 • G e o Stone weight of the prisoner, his height, his age, and an estimate of the musculature and tensile strength of his neck." In order to carry out a perfect hanging, the noose must, of course, be properly applied: D r a w it firm and tight with the free end of the rope emerging from the metal eye just under the jawbone. There is no knot. That fancy cowboy coil of a "hangman's noose (knot)" is something we abandoned to the Americans a hundred years ago. In Britain, the rope runs free through a pear-shaped metal eye woven into the rope's end, and the operative part of the noose is covered with soft wash-leather. Always adjust it to the left, because with the pull of the drop the noose gyrates a quarter-circle clockwise and the tug of the rope finishes under the chin. This motion throws the neck back and breaks the spinal column, separating it at about the third vertebra of the neck. Adjust it on the right and it gyrates to the back of the neck, throwing the head forward, not breaking the neck, eventually killing by suffocation. At this point I should mention that one had best not use mountain-climbing rope for a drop hanging, since it is designed to stretch in case of a fall. T h i c k manila rope is a much better choice. It is commonly believed that a black bag is placed over the condemned's head just before execution. Alas, contrary to all the movies, the bag is white. Actually, there's a bit more to say about it. T h e bag has been used in British executions from the later days of batch1

strangulation in public, long before the introduction of the long drop designed to sever the cervical vertebrae and cause spontaneous death. Its original purpose was to mask the contortions of slow strangulation, which were considered too horrible even for the ghoulish British public to witness, although the logic that public executions were a public deterrent against crime might have been followed strictly by exposing the ultimate horror in order to achieve the maximum deterrence.

Suicide and Attempted Suicide • 341 The number of capital crimes was reduced to fifteen in 1837, and, "In 1861, the death penalty was reduced to the offences of murder, treason, piracy with violence, and arson in the Sovereign's vessels, arsenals, or dockyards." Further restrictions ended judicial executions in 1964. More recent events, especially those related to Northern Ireland, have led the British public to favor the reintroduction of the death penalty for terrorism and other violent crimes. Interestingly, this was rejected by the House of Commons despite the largest Conservative majority in modern parliamentary history and the support of then-Prime Minister Margaret Thatcher (who, it should be noted, freed members of her party from party discipline— she wasn't known as "The Iron Maiden" for nothing—to vote their consciences). The result was due to an unusual alliance between those opposed on humanitarian grounds and those who wished to avoid producing martyrs for the I R A . 44

Pierrepoint looked back on his career with very mixed emotions: I believed with all my heart that I was carrying out a public duty. I conducted each execution [about four hundred] with great care and a clear conscience. I never allowed myself to get involved with the death penalty controversy. I now sincerely hope that no man is ever called upon to carry out another execution in my country. I have come to the conclusion that executions solve nothing and are only an antiquated relic of a primitive desire for revenge which takes the easy way and hands over the responsibility for revenge to other people. It is said to be a deterrent. I cannot agree.There have been murders since the beginning of time and we shall go on looking for deterrents until the end of time. If death were a deterrent, I might be expected to know. All the men and women whom I have faced at the final moment convince me that in what I have done I have not prevented a single murder.

342 • Geo Stone SUICIDAL HANGING

Since more than 95 percent of nonjudicial hangings are suicides, there is sometimes a predisposition on the part of investigators to see hangings through suicide-colored glasses. This can lead to overlooking or misinterpreting evidence. The previously mentioned case of Emmett-Dunne is cautionary. Most suicidal people are not very picky, and use whatever is handy. Household clothesline remains a big favorite. On the other hand, use of electric cords sometimes takes up the slack. Articles of clothing are also perennially popular. People have used belts, suspenders, shoelaces, scarves, handkerchiefs, neckties, shirtsleeves, pantlegs, and undershirts, among other things. 45

As previously noted, death occurs after five to ten minutes of complete brain anoxia. A broad ligature, such as a pant leg, may not produce enough pressure to fully cut off blood flow to the brain, let alone air through the trachea, and thus may take much longer to be fatal. Though a forensic medicine text warns, "Unusual ligatures arouse suspicion [of foul play]," it is not clear why that should be so, given the tendency to use whatever is available at the moment. Indeed, the same authors cite a case of a man who hung himself using some of the roots of a pine tree as the ligature, looped over a low branch of the same tree. Two studies, one of sixty-one consecutive hanging deaths in Seattle and the other of 106 hangings in New York C i t y show the range of materials used: 46

If the suspension point is inconveniently high, ligature material, similar or dissimilar, may be tied together. For example, bed sheets may be torn into strips and connected by knots. Usually a single simple loop is used, but multiple loops are not grounds for suspicion; quite the contrary, for the presence of more than one loop is unusual in murder, taking longer to apply and being harder to tighten. TYPE OF KNOT. Most common are the running noose (loop at one end, through which the other end is pulled) and the fixed noose with a granny or reef knot. Multiple knots are uncommon: "A ligature which is knotted firmly at the first turn and then knotted again after a second turn is unlikely to have been applied by a suicide; it is possible but rare." POSITION OF THE KNOT. The location of the knot is just about evenly distributed between left side, right side, and back of the neck; rarely is it in front. Some data on this are shown in Table 23.3. 49

In one case, a fifty-seven-year-old man hanged himself with a rope whose knot was in the front of the face at eyebrow level. A l l of the pressure was thus on the back, and to a somewhat lesser extent, sides of the neck. The exact cause of death was not clear: There was no sign of asphyxia, which is understandable since the airway was not obstructed, but pressure on the carotid arteries probably cut off the blood supply to the brain; or pressure on the carotid pressure receptors might have caused the heart to stop. The position of the ligature around the neck provides some distinction between hanging and strangulation, and thus clues to distinguish suicide (mostly hanging, rarely strangulation) from murder (almost always strangulation). In most suicides, the victim's weight causes the ligature to slide up to the top of the neck, under the jaw. Exceptions can usually be accounted for if: 1. The position of the body doesn't put much weight on the ligature. This can occur if the body is partially supported by, say, a chair. Similarly, if the victim was in a reclining position, there is little tendency for the ligature to move toward the top of the neck. 2. The victim has a particularly large thyroid cartilage (Adam's apple), which will limit the upward movement of a ligature. 3. A quickly tightening running noose, or a thin ligature, may clamp down pretty much where it was originally placed. In two studies of 279 suicidal hangings, the ligature was above the thyroid cartilage in 215 (77 percent), at the level of the thyroid cartilage in 43 (15 percent), and below in 19 (7 percent). Suicidal hanging typically causes a caret- (inverted V) shaped ligature mark. The tip of the caret is at the site of the knot, since the weight of the 51

Suicide and Attempted Suicide • 3 4 5 body normally causes the knot to be the highest point of a loop around the neck. This will not be seen if the body was at a reclining angle, and the ligature mark will make the death look like a strangulation. A running noose can also produce a horizontal mark, because it tightens quickly. If a soft, wide ligature is used, for example, a T-shirt, and the victim is cut down soon after death, there may be no visible external marks at all. Legal consequences can hinge on the ligature marks. In one case a man walked into the house and found his wife had hanged herself. To avoid the social stigma of suicide, he cut her down and hid the cord, before calling the police and telling them that he had found her collapsed on the floor. Had the rope marks on her neck not been clearly suicidal, he might well have been charged with murder. The ligature does not have to go entirely around the neck, as long as it compresses either the sides (blocks blood circulation to the brain) or the front (blocks airway) of the neck. In fact, there does not need to be a flexible ligature at all: People have died from resting their necks on stair tread edges, car steering wheels, and sofa or chair arms. In one case a sixty-year-old man was found dead in a kneeling position with the bottom of his chin balanced on the arm of a chair. The compression mark on his neck matched the chair arm, and extended to the carotid arteries. There was no bruising of neck muscle or injury to neck cartilage or bones. There was no evidence of alcohol or other drugs, nor of injury or debilitating illness. He had a history of severe coughing, and death was attributed to an attack of violent coughing or choking that had caused him to crouch down and then be unable to rise. 52

POINT OF SUSPENSION. A S with their indiscriminate choice of ligatures, suicidal people suspend themselves from whatever site is handy. Stair rails are popular, as is tying one end of the ligature to a doorknob and tossing the other end over the top of the door. Hooks and nails are useable, but may bend or pull out if not sturdy and firmly attached. Often a chair that the victim stood on is nearby, but total suspension is quite unnecessary; a majority of such suicides have their feet touching the ground. It's not generally appreciated that even low suspension points are sufficient; a table leg, doorknob, or bedpost have all been used. In one case a seventy-seven-year-old woman hanged herself from the leg of a table, with the 53

346 • G e o Stone 54

rope tied only 17 inches off the floor. She was found lying facedown. In another case, of a completely suspended woman, the seeming absence of a platform caused the police to suspect her husband. Luckily, the victim's footprints were found on top of a sewing machine near the body. 55

POSITION OF THE BODY. In one study, 37 percent (30 in 80) of hanging victims were completely suspended; 63 percent (50 in 80) were in contact with the ground This is credible, since all it takes to carry out a standing hang is to bend the knees enough to tighten the ligature. In 261 cases of incomplete suspension, 64 percent (168) had both feet touching the ground, 16 percent (42) were on their knees, 11 percent (29) were lying down, 7 percent (19) were sitting, and 1 percent (3) were huddled or squatting. SUICIDE PACTS AND HANGING. While suicide pacts are not uncommon, dual hangings are rare. In one case, two men were found dead in their hotel room, one on either side of the closet door. The bedsheet had been tossed over the door and opposite corners tied to their necks. Each had been on a chair and had stepped off simultaneously. In another instance a woman and a man, despondent lovers, tied a rope to a branch of the tree under which they were sitting. They attached the free ends to their necks and leaned back. Acts like these require planning, coordination, and trust. 56

57

58

59

SUICIDE BY HANGING COMBINED WITH OTHER METHODS. There exist several reports where a person attempted to commit suicide by one method, became impatient, and finished the job by hanging. In one instance a man drank ammonia (not recommended) and then hung himself. Presumably the ammonia was too slow or too painful. In another case, a fifty-three-year-old woman was found hanged in a loft. There was considerable blood, widely scattered, from a depressed skull fracture and other scalp wounds. She had apparently first cut herself with a knife, which was found in her pocket, followed by a blow to the head from the butt of a hatchet. Bleeding profusely (scalp wounds tend to be messy), she found a rope, formed a running noose, and hanged herself. 60

61

Finally, there was a forty-eight-year-old man who slit his left wrist and throat. The wrist injury was deep but the throat cuts were too shallow to be fatal. He followed this by two gunshots, one through his left palm and the other to the right temple. This latter bullet did not pene-

62

STRANGULATION

Strangulation is defined as pressure applied to the neck without suspension of the victim. It is uncommon in suicide, but not unknown. Nevertheless, most strangulations are homicide, and will be treated as such by medical examiners and police, in the absence of clear evidence to the contrary. Strangulation was used as a method of execution in some countries, for example, Turkey and Spain. In Spain, the sitting victim was tied to a post. A metal collar was placed around the neck and the post, and then tightened. In one version, a metal spike stuck out of the post and was forced into the base of the prisoner's neck by the pressure of the tightened collar. The physiology of strangulation is essentially the same as that of suspension hanging and needs not be treated separately. In self-strangulation, the ligature is applied more slowly and less tightly than in suspension hanging. As a result, the jugular veins are more constricted than are the carotid arteries, leading to a blue, swollen head. Neck injuries, however, are rare. Because the ligature cannot slide up the neck or be supported by the chin, compression of the airway is more likely than in suspension hanging. In suicidal strangulation, people generally use the materials at hand. Women tend to use stockings or scarves; men most often use cord. In one case a man strangled himself with two bowties. In another instance, a man wrapped thirty-five turns of twine around his neck, tied a knot, and attached the free end to his right thumb in order to increase pressure. His blood alcohol level was 0.26 percent. 63

64

Two or more turns tied with a half-knot or half-hitch (double knots are more characteristic of murder) is strong evidence of suicide, but there are exceptions. The murdered forty-two-year-old woman described in the A s phyxia chapter was such a case. More typical of self strangulation were two women who killed themselves with stockings. In one case, a seventy-three-year old woman, depressed and about to be committed to a mental hospital, wrapped a stocking twice about her neck. There was a half-knot at each turn. Because the ligature was only

348 • G e o Stone

tight enough to compress the jugular vein (blood out) but not the carotid artery (blood in), her face was purple and congested. In the other example, a similar stocking was pulled more tightly and the face was not engorged or cyanotic. It's possible for a person to strangle him/herself with one arm: A woman with incapacitating burns on her right hand rolled a shawl and scarf into a ligature, wrapped it two-and-a-half times around her neck and tied two knots. Another method is use of a tourniquet. A single loop of rope is loosely tied around the neck with a good knot, for example, a square or reef knot. A rod is put between the ligature and the neck and is then twisted until the desired degree of tightness is achieved. The rod tends to unwind a bit when the suicide becomes unconscious, but usually snags on the side of the jaw, maintaining enough tension to cause death. (See Asphyxia chapter for details.) 65

CONSEQUENCES: WHAT ARE THE EFFECTS OF HANGING?

There is not much information from survivors for two reasons: (1) There are not many survivors, and (2) often, survivors have more or less complete amnesia. In one case, a woman tried to hang herself from the foot of her bed, while in jail. She was saved by a fellow prisoner. She later mentioned having had severe pain, followed by unconsciousness. In another instance a public entertainer, who hung himself briefly as part of his act, made a mistake of timing. He said (afterwards) that he could not breathe—quite understandable, under the circumstances—and felt as if a heavy weight was on his feet. He lost consciousness before he could move his hands to release himself. There is additional information from experimental hanging. In one description, the subject mentioned flashes of heat and light, and deafening sound. Legs were numb and weak. Pain was not severe and unconsciousness was sudden. More detailed information came from another self-experimenter named Minovici. W i t h 5 kg (11 lbs) pull on the ligature, loss of consciousness was rapid. When he leaned on the rope (incomplete suspension), within five or 66

68

Suicide and Attempted Suicide • 3 4 9 six seconds his eyes blurred, he heard whistling, and his face turned red-violet. W i t h the knot on the side instead of the back of the neck, these effects took eight or nine seconds to appear. When he tried complete suspension, as soon as he left the ground, he couldn't breathe or hear his assistant. He experienced such severe pain that he immediately stopped the test. W i t h i n ten minutes, many small hemorrhages could be seen near the site of the rope; these remained visible for eight to eleven days. For ten to twelve days later he had watering eyes, trouble swallowing, and a sore throat. After unconsciousness, convulsions follow. In thrashing around, the victim may make enough noise to attract attention, wanted or unwanted. For instance, 69

A man aged twenty made a noose with a silk stocking and hung it on a hook behind the door of his room. He climbed on to a chair; put his head through the noose and stepped off "to see if his feet would touch the floor" He found his feet were a few inches short. The slip knot tightened and he was unable to release the pressure on his throat. During his struggles he kicked a chair over and, when his mother heard the noise, she went to discover the cause.The man was then unconscious but she had the presence of mind immediately to cut the stocking. After a brief stay in hospital he was able to return home. 70

The face color can range from pale to cyanotic blue, depending on whether or not much blood was trapped in the head region. If the ligature put only enough pressure on the neck to close the jugular vein but not the carotid artery, a swollen, blue, blood-congested face is the result. The tongue may be swollen for similar reasons. In fourteen of forty (35 percent) cases, the tongue protruded from the mouth. The small hemorrhages previously mentioned occur in about 10 percent of cases, generally the same ones that have blood-engorged faces. Interestingly, the faces of many (twenty-one of forty) hanging victims were described as placid, in contradistinction to those strangled, choked, or smothered. A n d , curiously, sometimes the right eye stays open and has a EXTERNAL APPEARANCES.

CONSEQUENCES: WHAT HAPPENS TO HANGING SURVIVORS? DROP (JUDICIAL-TYPE) HANGING. There are no survivors of a properly done drop hanging; the broken neck (similar to some car-crash neck injuries) is invariably fatal. Even when the neck is not broken, injury is severe and debilitating.

Since only around 1 percent of suicidal hangings are of the drop type, there are correspondingly few spinal cord injuries. In suspension hangings, damage to neck structures occurs about one-third to onehalf of the time, but is not normally life-threatening. Both death and permanent injury are due to cutting the oxygen supply to the brain. The severity of brain damage depends on how completely and how long the brain is oxygen-starved. M i l d hypoxia (not enough oxygen) causes behavior resembling drunkenness: physical and verbal incoordination, but no permanent harm. W i t h complete anoxia (no oxygen taken in, but heart and blood circulation uninterrupted), unconsciousness occurs after about two minutes and coma in about five. If blood circulation to the brain is totally stopped, loss of consciousness follows in eight to fifteen seconds. Recovery may take minutes to days, and may not be total. After about four to five minutes of anoxia, permanent brain damage becomes increasingly l i k e l y Five of thirty-nine people rescued from near-hanging had such persistent injury. SUSPENSION HANGING. 74

77

On the positive side, there are rare, but well-documented, cases of spontaneous remission of depression after near-hanging. DROP HANGING. Drop hanging may not be instantly fatal and, "the possibility of briefly retained consciousness in some cases appears quite real." You might be wondering how this was determined. In a study of thirty-four skeletons of people who had been judicially hanged between 1882 and 1945, a substantial number did not have a broken neck. Interestingly, the average drop for this group was 83 inches; for those whose neck was broken the average drop had been only 74 inches Thus, "the length of the drop, though important, does not produce expected or consistent results." 78

81

Suicide and Attempted Suicide • 351 In the event of miscalculation leading to an inadequate fall, the victim will undoubtedly suffer some more or less severe neck injury, but will die within five to ten minutes of asphyxiation, carotid/jugular compression, or tears of the vertebral arteries (leading to massive hemorrhage). SUSPENSION HANGING. In addition to brain damage, there may be heart and/or lung injury. For example, there is a syndrome found, among other cases, in hanging survivors; it's called adult respiratory distress syndrome (ARDS) and is characterized by progressive respiratory failure that is hard to treat and is not helped much by supplementary oxygen administration. The cause is not well understood: It may be due to brain injury from lack of oxygen; an alternative explanation is that fluid fills the lungs (edema) because of the high negative pressure in the lungs due to trying to inhale against a blocked airway; other possible mechanisms have been proposed. In any case, various types of lung damage are the most frequent cause of delayed death in near-hangings. Some case reports may be useful. 82

83

1. A thirty-three-year-old man was jailed for shoplifting. He tried to hang himself with his shirt and was cut down after an undetermined time. Examination two hours later showed deep coma, which did not change over twelve hours. Gradual improvement occurred over the next two days, and he became awake and alert; however an E E G (electroencephalogram) after five days showed residual brain injury. On the seventh day, lung damage appeared; potentially fatal infection followed quickly. Two weeks of intensive care saved his life. A month after the initial admission he was committed to a state mental hospital. 84

2. A twenty-nine-year-old man was jailed for assault on his ex-wife and a police officer. Later that night he hung himself with a T-shirt "for several minutes" before being cut down. He was also in a deep coma and unresponsive to deep pain. On the second day he began to improve, but his speech was, and remained, halting and often incoherent. After twelve days he was committed to a state mental hospital. 3. A fourteen-year-old boy was found hanging from bleachers by (means of) a jacket he had wrapped around his neck. He was released after being suspended for an estimated five to ten minutes. He opened his eyes sponta85

352 • Geo Stone neously, but had no verbal or motor response to painful stimuli. In the hospital his coma score improved (he reacted to pain), but lung damage quickly appeared. After four days he was transferred to another hospital, but his neurological improvement at that time was limited to opening his eyes when told to. 4. Finally, there is a fascinating case in England from 1650. Anne Green was a twenty-two-year-old maid in the house of Sir Thomas Read. She became pregnant by Sir Thomas's grandson, Geoffrey, and gave birth to a stillborn boy. She hid the baby's body, was discovered, convicted of murder, and hanged. She was suspended for half an hour during which time some of her friends were "hanging with all their weight upon her legs, sometimes lifting her up, then pulling her down again with a sudden jerk, thereby the sooner to dispatch her out of her pain," until forced to stop by the undersheriff who was worried about the rope breaking. When she was considered dead the body was removed, put into a coffin, and taken to a nearby house. When the coffin was opened, she was seen to take a breath. The physicians, intending a dissection, tried to revive her instead. Because of (and despite some of) their efforts, she recovered fully, except for amnesia about some of the events of the hanging. She was subsequently pardoned, in an attempt to cooperate with what was taken to be divine intervention. She eventually went back to the country, taking along her coffin as a souvenir. She married, had three children, and lived another fifteen years. 86

PRACTICAL MATTERS: HOW TO DO IT

If you intend to hang yourself, the next major decision is whether to do a drop (judicial-type) or suspension job. Each has some advantages and disadvantages. HANGING SUSPENSION: (1) Can be done with a wide range of ligature materials—most anything will work; (2) can be carried out by invalids, without leaving their room; (3) is fairly quick, probably not painless (but unconsciousness is rapid), but may have severe consequences—brain damage—if interrupted; (4) doesn't require much knowledge to accomplish.

Suicide and Attempted Suicide • 3 5 3 To carry out a suspension hanging, you can simply tie one end of the ligature to a fixed point (doorknob, hook, rafter, etc.) and the other end to your neck. You can and should protect the airway from unnecessary compression and pain by firmly padding the front quarter of the neck and (more important) by placing the knot high and at the front of your face. Complete suspension is unnecessary and is generally more painful than partial suspension; however, standing on and kicking away a chair is sometimes done in the same spirit as diving, rather than wading, into icy water. Unconsciousness occurs quickly and without enough warning to count on time to change your mind: This is a lethal method and is not suitable for a "suicidal gesture." You need an uninterrupted twenty minutes (half an hour to take into account last-minute vicissitudes) to be sure that you won't be cut down and "saved" with permanent brain damage. Since you may thrash around while unconscious, take into account the possibility of attracting unwanted intervention because of the noise. Because the cadaver is sometimes gruesome and always shocking, consider not hanging yourself where loved ones will find the body. If you use a hotel or motel, leave a good tip for the cleaning person. (1) Requires a strong, low-stretch rope. Manila (sisal) or hemp works (2) requires a 5 to 15 foot drop (see drop table or calculations); (3) is quick, possibly painless—nobody knows, and none of the questionnaires have been returned—and generally cannot be interrupted once set into motion; (4) requires detailed knowledge of how and where to attach rope, how and how far to jump (down, but not out), and a place to jump from. To execute a drop hanging, the drop distance can be estimated as follows, DROP:

drop in feet =

1260 your weight in pounds

The type of knot is not important as long as it doesn't loosen. However, its position is, unlike in suspension hanging, critical. The knot should be as near the chin as convenient, and in any case no further back than the cheekbone. Note which way the knot rotates when pulled up, and adjust it to the side of your head so that it will rotate toward the chin and snap the head back-

3 5 4 • Geo Stone wards. If it ends up behind the ear, it will be much less likely to produce a cleanly broken neck, and may leave you to strangle unpleasantly. The drop should be as close to straight down as possible; don't take a running jump. The rope should be at least an inch thick and must not be one intended to stretch in order to ease a fall, for example, mountain-climbing rope. A t tach the other end to something that won't break or come loose. This method is harder to get the hang of than is suspension, and is not recommended unless you're confident that you fully understand it. Mistakes usually transpose into some unpleasant form of suspension hanging, unless the rope breaks. SUICIDAL

STRANGULATION

If, for some reason, there is no attachment point available for a ligature, strangulation is a possibility. This method consists of wrapping a cord around your neck and tightening it. The disadvantages are: (a) Depending on the amount of tension applied, it may compress your airway as well as the major blood vessels (carotid and/or jugular) unless you protect the front of the neck; (b) since there is no weight on the ligature, it may loosen when you become unconscious. Some methods to solve this latter problem are: • use a high-friction ligature that will stay in place; • use a double knot; • wrap thin cord, as many times as possible in five to ten seconds, around your neck, relying on friction to maintain the tension. A slip knot is helpful, but may loosen unless wrapped; • make a loose loop around your neck. Insert a thin, rigid item, for example, a wooden spoon or pen, between the neck and the loop, and twist the rod until it tightens the ligature; then tuck the end of the rod between the neck and the cord to keep it in place. If you use a bar that is around 8 inches (20 cm) long, there is a good chance that it will stay in place under your chin even if not tucked in. The most reliable of these methods is to buy a racheting "tie down." These are available at auto, motorcycle, and some hardware stores for between $5

Suicide and Attempted Suicide • 3 5 5 and $10 and are generally used for attaching cargo. Once tight, a springloaded cam release (or equivalent) must be pressed to remove tension. The main caveat is that, if you're not familiar with them, it may take a few minutes to figure out how the racheting mechanism works. A friction-actuated version is easier to use, and is also easier to release, but can't be tightened as much. In all cases, bending forward increases the diameter of the neck, and thus the constrictive effect of the ligature. Drop hanging, suspension hanging, and ligature strangulation are effective and lethal means of suicide and are not suitable for a suicidal gesture. Drop hanging requires knowing what you're doing and is unforgiving of mistakes; its main virtue is that it is quick and, allegedly, painless. Suspension or ligature asphyxia requires about an uninterrupted half hour, does not require complete suspension, and can be carried out by people with limited physical abilities. Pain can be minimized by protecting the front of the neck. Since finding such a cadaver may be traumatic, care should be given to choosing a location.

WHAT IS HYPOTHERMIA?

The freezing point of water, under standard conditions, is 32 degrees F (0 degrees C) and its boiling point is 212 degrees F (100 degrees C). Normal human body temperature is around 98.6 degrees F (37 degrees C) and is tightly regulated by a variety of physiological mechanisms. Even a 3.6 degrees F (2 degrees C) change is significant; a 5.4 degrees F (3 degrees C) fever is a medical emergency. Systemic hypothermia is generally defined as a body temperature below 95 degrees F (35 degrees C). Severity is rated by how low the core body temperature falls: 89.6 to 95 degrees F (32-35 degrees C) is mild hypothermia; 80.6 to 89.6 degrees F (27-32 degrees C) is moderate; below 80.6 degrees F (27 degrees C) is severe. Hypothermia is also divided into "acute" and "chronic" categories. Acute hypothermia occurs quickly, roughly within two or three hours; chronic hypothermia takes longer. W h i l e the boundary is fuzzy, the distinction is more than academic, since both treatment and prognosis differ between the two.

WHAT CAUSES HYPOTHERMIA?

Hypothermia occurs when the quantity of body heat lost to the external environment substantially exceeds the heat generated from metabolism. This can be caused by a decrease in heat production, or an increase in heat loss, or both. HEAT PRODUCTION

L o w heat production is usually due to insufficient food, illness, injury, or some drugs. An average resting body gives off about 50 kilocalories (kcal) or "kitchen" calories—the same calories you see on food labels—of heat per square meter of skin per hour. Multiplied by the average person's 1.7 square meters of skin

Suicide and Attempted Suicide • 3 5 9 and 24 hours, you lose around 2,000 kcal per day to the outside world, which is about the amount that you generate at rest from the food that you've eaten. This is called "basal metabolism." If your muscles are working, metabolic heat production goes way up. For example, while you're shivering, you generate roughly five time as much heat as when sitting quietly; while exercising, ten times as much. 1

However, exercise is a two-edged sword in hypothermia. While it produces heat, which is needed to keep body and mind functioning, it also increases blood flow to your active muscles, and thus heat loss from them. In addition, it uses up energy stores quickly. The decision whether to exercise in a potentially hypothermic situation depends on the circumstances: H o w long the conditions are expected to last, availability of food and shelter, and need for clear thinking. To some degree there is no choice in the matter: shivering is a form of involuntary exercise. It increases heat production by 200 to 700 percent, but is accompanied by an increase in blood flow to/from the muscle, resulting in about a 25 percent increase in heat loss, too. Shivering is an effective means of generating heat, until muscles run low on energy. 2

The common warning against going to sleep in the cold is certainly appropriate if you're in the process of walking out of trouble, but that is not always the right thing to do. For example, someone with reasonable cold-weather clothing caught in a mountain blizzard might be better off building a snow-hole or shelter, staying as dry and warm as possible, and sleeping through the storm. HEAT LOSS

Excessive heat loss is due to cold surroundings or to a failure in the body's temperature regulating mechanism. There are four physical mechanisms of heat loss: 1. Convection: heat loss by means of molecular transfer of energy via air or water currents. 2. Conduction: heat loss by touching something that's colder than you are. This is, fundamentally, the same process as convection, but mostly applies to solids.

360 • Geo Stone 3. Radiation: heat loss from invisible infrared-wavelength energy you give off. 4. Evaporation: heat loss from the cooling effect of changing a liquid into a gas. Looking at these in more detail: CONVECTION AND CONDUCTION

Most heat loss in hypothermia is from contact with cold air or cold water: You're always generating a micro-environment of warm air (or water, if that's where you are) around your body, but this is easily stripped away by air/water currents or your own movements. You can easily demonstrate this by putting your hands into a container of cold water, and holding them still for a few seconds. If you then move your hands, they will feel suddenly colder, as unwarmed water contacts them. At a molecular level, what happens is that cold air/water molecules hit your skin, pick up some heat (energy) and bounce off, leaving cooler skin behind (hot air/water warms you by the same process, with the hot molecules transferring energy to your skin). This cooler skin, being in contact with the rest of the body, is in turn warmed by the body core, which is thereby cooled. The colder the air/water molecules, the faster this occurs. The rate of convective heat loss also depends on the density of the moving substance (heat loss in water is much faster than in air of the same temperature) and the velocity of the moving substance (the faster the air/water current, the faster the heat exchange). Another variable in heat loss is surface area. The more surface area, the more heat transfer. Curling up in the fetal position minimizes heat exchange by minimizing surface area, and thus evaporation, radiation, and convection. It may also be comforting for atavistic reasons. W i t h cold air, some of the variables that affect heat loss are: temperature, wind speed, insulation, and humidity. We'll look at their effects in a bit more detail. WIND. W i n d speed is the cause of the often-misunderstood "wind-chill factor." "Wind chill" is just a practical demonstration of air convection and involves nothing more complicated than wind removing the warmed (by you)

Suicide and Attempted Suicide • 361 air molecules from near your body and replacing them with cold ones. This results in your body being hit by more cold air molecules per minute, and so being cooled more. For example, 0 degrees F (-18 degrees C) with no wind causes heat loss at the same rate as 30 degrees F (-1 degrees C) and 25 mileper-hour (40 kilometer-per-hour) breeze. However, the latter case would not drop below 30 degrees F (-1 degrees C), in the absence of evaporative effects. 3

A second consideration, which is not technically part of wind-chill factor calculations but is biologically important, is that more wind will cause faster evaporation of sweat. This will remove from your body around two and a half kilocalories per teaspoon of evaporated sweat, and thus additional cooling. Evaporation cools you because energy (heat) is always required to change a liquid into a gas. If the liquid is on or near your skin (sweat, water, or wet clothing), the heat comes from you, leaving you cooler. This is handy in the desert, but not so good if you're trying to keep from freezing. Thus, a dry body will cool faster in the presence rather than in the absence of wind ("wind chill"), but it won't get below ambient temperature. A wet body in the wind will cool both faster and further, and may drop far below ambient temperature. EVAPORATION.

RADIATION. Another way heat is lost is by radiating it away in the form of infrared (electromagnetic) energy. This requires a temperature difference between you and the outside world. The greater the difference, the larger and faster the heat loss (or gain, if the environment is at a higher temperature). Infrared wavelengths are longer than the unaided human eye can detect, but electronic enhancement permits these wavelengths to be "translated" into our visible range. One sort of night-vision goggles is sensitive to infrared wavelengths, allowing you to see things that are at a different temperature than their background. (Another kind amplifies existing light.) Since about one-fifth of the heart's output of blood goes to the head (15 percent to the brain), it's not surprising that in cold weather an uncovered head may be responsible for more than half the body's total heat loss. Under these circumstances a bare head shows up, on an infrared detector, like a beacon. 4

INSULATION.

External insulation consists of clothing and shelter. In cold cli-

362 • Geo Stone mates both function to keep the air nearest your body, which you have spent precious calories warming, from leaving quickly and being replaced by cold air. Sweating increases heat loss in two ways: In addition to causing heat loss from evaporation, it replaces some trapped air in clothing and blankets. Since water conducts heat about 25 times faster than does dry air, this will increase heat loss under cold conditions. c6

Some materials, like wool and a variety of synthetics (Fiberfill, Holofil, Capilene, Thermax, etc.), maintain their loft (and thus insulating ability) better than others (cotton, down) that mat down when they get wet. Nevertheless, any clothing that gets wet or even damp will allow faster heat loss than would the same item dry. Internal insulation involves fat and bulk. It is not an accident that mammals in cold climates are, as a rule, larger than closely related warmer-environment species. They also have a smaller surface-to-volume ratio; they are rounder and have smaller ears, nose, and tail, and thus less heat loss. You can see these differences if you compare, say, cold- and warm-region rabbits or bears. d

Fat is very useful in cold climates. Because fat tissue has relatively low blood flow, it acts as a good barrier to heat loss from important core organs. Equally important, it also is a concentrated metabolic energy (heat) source, providing about 9 kilocalories per gram, compared to some 4 kcal per gram of protein or carbohydrate. HUMIDITY. The low humidity level of frigid air can play a role in hypothermia. On the one hand, the higher the humidity (gaseous water molecules), the more particles will be available to snatch heat from the skin (though this is offset by the lower density of warm air). On the same side of the equation, humidity will decrease the insulating properties of clothing. However, the humidity is limited by the temperature. For example, the maximum possible humidity at 32 degrees F (0 degrees C) is only one-tenth the maximum at 98 degrees F (36.6 degrees C). Thus, at temperatures below the freezing point of water there simply isn't enough gaseous water in the air for these processes to matter much. On the other hand, low humidity increases the net evaporation of sweat, which is a major cooling mechanism (and which is why people are much less

Suicide and Attempted Suicide • 363 comfortable on a hot humid day than a hot dry one). L o w atmospheric humidity can also contribute to dehydration for other reasons, since (1) the body sweats to keep skin from drying out (a humidity level of 70 percent nearest the skin is ideal); (2) exhaled air is close to 100 percent relative humidity. (The condensation you see from your breath on a cold day is a visual reminder of this.) I estimate the daily amount of water lost in breath at freezing temperatures to be about 1.3 pints (0.6 liters).

DEMOGRAPHICS: WHO DIES FROM HYPOTHERMIA?

In a recent study of 234 cases of hypothermia in Switzerland, 43 (18 percent) were attempted suicides, 141 were due to accidents or mountaineeringrelated, and the rest were attributed to a variety of causes. Three-quarters occurred in cold air; the others in cold water. Sixty-eight (29 percent) of the 234 died. The coldest survivor had a core temperature of 63.5 degrees F (17.5 degrees C) and the longest heart stoppage in a survivor was 4.75 hours. Hypothermia is not uncommon among the elderly, who often are in frail health, frequently live alone, and may not be able to afford adequate heating or food. These people are at high risk of dying of cold. In some British studies, 3 to 4 percent of elderly admissions to hospitals were hypothermic. Similar circumstances apply to the homeless; in Chicago, 8 of 22 (36 percent) hypothermia deaths were among the homeless. In the United States there were an average of 780 annual deaths attributed to hypothermia between 1979 and 1990; however, only a handful (less than ten a year) are officially suicides. 7

You might be surprised—I certainly was—at the geographical distribution of the top ten hypothermic-death-rate states in the United States. While Alaska and Illinois are northern states with severe winters, the others are not: Alabama, South Carolina, North Carolina, Virginia, Arizona, New Mexico, Oklahoma, and Tennessee. What's going on here? Cold weather turns out to be only one of several relevant factors. Another is how quickly and unpredictably temperatures change, due to unstable weather patterns, as in the Carolinas and Virginia. H i g h elevation and clear skies cause large temperature drops from day to night time; this is the situation in New Mexico and Arizona (twenty-three 11

3 6 4 • Geo Stone people died of hypothermia in New Mexico during the 1993-94 winter). It may also be that people in the south have little experience with severe cold and underestimate its danger. Two other interrelated factors are poverty (people can't afford adequate shelter and heat) and a high proportion of older residents; older folks are more susceptible to cold injury, more likely to be poor, and more likely to live alone and unnoticed. H a l f of hypothermia deaths in this country are among people sixty-five or older. 12

WHAT ARE THE PHYSIOLOGICAL EFFECTS OF COLD? TEMPERATURE REGULATION. Central temperature regulation in mammals is located in the anterior hypothalamus section of the brain. It is sensitive to blood temperature changes of as little as 1 degree F (0.5 degrees C) and also reacts to nerve impulses sent from nerve endings in the skin. Injury or tumors in the hypothalamus can lead to fatal loss of thermal control even at room temperatures. HEAT CONSERVATION. In cold conditions, heat is first conserved by decreasing blood flow to the skin and skeletal muscles, and is controlled by the "sympathetic" nervous system. Interestingly, some marine mammals, such as seals, have an additional full-time heat conservation method called "countercurrent" blood flow. Normally, warm-blooded creatures in cold water would be expected to lose a lot of heat from their flippers and fins, which have and need a large surface area for propulsion. However this heat loss is decreased because the arteries and the veins in the flippers/fins run right next to each other. This allows heat transfer between the two and means that some of the heat contained by the arterial blood warms the returning venous blood rather than being wasted in warming the seawater. Very crafty.

In humans, typical blood flow to the skin is 300-500 ml/min. Maximum physiological constriction can decrease this to around 30 ml/min. One of the consequences of this is that blood will pool in the core organs at higherthan-normal pressure. This, in turn, forces the kidneys to increase urine output ("cold diuresis"), which is only a minor heat loss, but may be a significant cause of dehydration, and increases the load on the heart because the blood is more viscous. Nothing has only one effect.

Suicide and Attempted Suicide • 365 Heat Generation. Additional heat is generated by shivering. This reflex is set off by lowered temperature either in the skin or deeper in the body. The fact that it is not under voluntary nervous control is shown by its existence in paraplegics and in people temporarily paralyzed by curare. Shivering continues down to a core temperature of around 90 degrees F (32 degrees C ) , but falters below there, and stops altogether at around 86 degrees F (30 degrees C ) . It also ceases, during slow hypothermia, if muscles use up their energy stores (glucose/glycogen); this occurs after a few hours. In either case, body temperature drops precipitously after the shivering reflex fails. e13

"Goosebumps" (piloerection), which lift hairs or feathers away from the body, increase the amount of trapped air—insulation—near the skin. U n fortunately, since humans are more-or-less hairless over most of their bodies, this process doesn't do us much good. But it was a fine idea when we were furry and is still an interesting sensation. RATE OF HEAT LOSS. A S a practical matter, most hypothermia is the result of contact with either cold air or cold water. Since air has a much lower ability to remove heat than does water, hypothermia in air normally takes many hours and is usually "chronic" or "slow." "Acute" (fast) hypothermia, generally in or due to water, has some significantly different characteristics from the chronic variety. In slow, as compared to fast, hypothermia, the body has more time to make some physiological responses: Deep veins are in a "neurovascular bundle," with arteries and veins next to each other. Cold causes a shift of blood from surface veins to deeper ones. Thus, like the marine mammals mentioned earlier, we have a way of warming the returning venous blood with outgoing arterial blood. In warm conditions, where getting rid of excess heat is necessary, the surface veins carry more blood and this "countercurrent heat exchange" is minimized. Blood flow to the limbs and skin decreases, blood pools in the core organs, and shivering continues until metabolic energy supplies are depleted. People develop the physical and mental lethargy commonly associated with hypothermia. One of the hazards specific to fast hypothermia is a phenomenon called "afterdrop," wherein the core temperature continues to fall even after a person has been taken to a warm place. This is because blood vessels in the arms f

366 • Geo Stone and legs get larger (dilate) as they start to be rewarmed. As a consequence: 1. Blood moves from the core into the limbs (which, despite warming, are still colder than the core), and gets chilled further. This results in more cold blood moving from the periphery into the core, further decreasing core temperature, which can be lethal; 2. Redistribution of blood from the core to the periphery decreases blood pressure, and may lead to heart failure ("shock"); 3. The stagnant blood from the limbs is very acidic (from lactic acid and carbon dioxide buildup), which may cause cardiac arrhythmias and death. Afterdrop can best be avoided by not rewarming the periphery until after warming the core. This was observed by one of Napoleon's army doctors during the retreat from Moscow, when he noticed that the hypothermic soldiers placed closest to warming fires tended to die more often than those further away Fatal chilling may occur before physical and mental abilities are seriously retarded: In 1980, sixteen Danish fishermen spent about one-and-a-half hours in the North Sea when their boat went down. When rescued, all could climb into the cargo net, and walk across the deck of the rescue vessel. They went below to the galley for hot drinks (good idea) and to warm up quickly (bad idea). Every one of them died of afterdrop hypothermia. 15

SUSCEPTIBILITY TO COLD

There are age, race, and gender differences affecting susceptibility to cold. Infants and the elderly are much more likely to be injured than are young adults. Fat people are less subject to hypothermia than are thin ones. M e n are more vulnerable to hypothermia than are women, even though they are larger, because women have more subcutaneous fat, which is better insulation (less blood flow) and stores more energy (more calories per gram) than muscle. Blacks seem more sensitive to cold than are Inuits or Caucasians. Interestingly, Australian Aborigines apparently lower their body temperature (and, as a result, metabolism and food needs) to around 95 degrees F (35 degrees C) on cold nights. 16

g17

Suicide and Attempted Suicide • 367 EFFECTS OF COLD BEHAVIOR AND REFLEXES. In slow hypothermia, by the time body temperature drops to 90 degrees F (32 degrees C) both the central and peripheral nervous systems are impaired, primarily due to decreased blood flow to the brain (6 to 7 percent per degree C ) : People become physically and mentally clumsy, show decreased sensitivity to pain, have slowed reflexes, and may hallucinate. Thus, a medical school mnemonic for hypothermia symptoms: "stumbles, mumbles, fumbles, and grumbles," which summarizes changes in motor coordination and consciousness. 18

Sleepiness ("cold narcosis") occurs at around 86 degrees F (30 degrees C) core temperature. At around 81 degrees F (27 degrees C), people stop responding to verbal commands and some reflexes (such as the reaction of eye pupils to light) stop working entirely. Knee jerk is the last reflex to go, at 79 degrees F (26 degrees C). The body's temperature-regulating mechanisms also fail and there is quick cooling until the body reaches ambient temperature. However, there is the usual individual variability, with recorded reflexes as low as 68 degrees F (20 degrees C ) . HEART. The heart's response to hypothermia is usually the actual cause of death. Initially, the heart merely slows down and shows some electrocardiograph changes. Dehydration—blood really is thicker than water—makes it harder for the heart to pump increasingly viscous blood. Ventricular fibrillation is often—but not always—seen below 89.6 degrees F (32 degrees C), and reaches a maximum between 82.4 and 86 degrees F (28 to 30 degrees C ) . h19

21

Ventricular fibrillation occurs when different parts of the muscle surrounding the main pumping chambers beat in a chaotic, unsynchronized fashion; as a result the heart can't send blood through the arteries—with fatal consequences unless reversed. In hypothermic conditions fibrillation may easily be set off by even minor exertion. If the heart escapes fibrillation, it slows further as the temperature drops. In one case, a woman had a pulse of four beats per minute (around 75 per minute is normal) with a body temperature of 52 degrees F (11 degrees C), and the heart stopped pumping entirely at 51 degrees F (10.5 degrees C). Her heart restarted when she was rewarmed. 22

A t normal body temperature, brain damage starts in about five minutes, in the absence of blood flow; at lower temperatures the length of time before brain (and other organ) injury is substantially longer. This is because cellular meBRAIN.

368 • Geo Stone tabolism and oxygen needs drop sharply with lowered temperature. For example, oxygen consumption is reduced by 50 percent at 82.4 degrees F (28 degrees C); 75 percent at 71.6 F (22 degrees C); and 92 percent at 50 F (10 degrees C ) . However, people whose bodies cool down faster than they run out of oxygen (for example, fast hypothermia in air, drowning in icy water) can be revived longer. Those who run out of oxygen faster than their temperature drops (for example, avalanche, drowning in warmer water) will not be revivable as long. Some hypothermic people have been given C P R for up to 3.5 hours and have recovered without neurological damage. 23

CAUSE OF DEATH

Death is generally from circulatory failure: The heart either goes into ventricular fibrillation or slows down and stops altogether. In people who have survived the first couple of days after rescue, organ failure, particularly of the pancreas, may lead to delayed death. A wide range of other organs also may show acute damage from cold, but these injuries, while sometimes severe, are not usually fatal. 24

SIGNS AND SYMPTOMS OF HYPOTHERMIA

Looking at signs and symptoms in relation to specific temperatures, rather than by organ systems, give a somewhat different perspective. The following chart shows the body core temperature and corresponding signs and symptoms. Not all hypothermic people exhibit all of these symptoms, which will also change as the person's core temperature changes. 25

Suicide and Attempted Suicide • 369 93 to 90F (34 to 32C)

Violent shivering persists, difficulty speaking, sluggish thinking, amnesia starts to appear and may be retrograde, gross muscle movements sluggish, unable to use hands, stumbles frequently, difficulty speaking.

90 to 86F (32 to 30C)

Shivering stops in chronic hypothermia, exposed skin blue or puffy, muscle coordination very poor with inability to walk, confusion, incoherent, irrational behavior, but may be able to maintain posture and the appearance of awareness.

86 to 82F (30 to 27.7C)

Muscles severely rigid, semiconscious, stupor, loss of awareness of others, pulse and respiration slow, pupils can dilate.

82 to 78F (27 to 25.5C)

Unconsciousness, heart beat and respiration erratic, pulse and heart beat may be unobtainable, muscle tendon reflexes cease.

78 to 75F (25 to 24C)

Pulmonary edema, failure of cardiac and respiratory centers, probable death. Death may occur before this level.

WHAT ARE THE CLINICAL SIGNS OF HYPOTHERMIA?

In addition to the behavioral symptoms mentioned, there is often swelling, especially of the face and ears, as fluid leaks out of the circulation. This is another cause of viscous blood, which overworks the heart. Blood pressure is low and sometimes unmeasurable, as are pulse and respiration. There may be no signs of life whatsoever below temperatures of 64 to 81 degrees F (18 to 27 degrees C ) . A n d with good reason: Most of these people are dead. However, there have been occasional cases of survival despite extreme temperatures. Perhaps the most astonishing was that of a man found with a body temperature of 32 degrees F (0 degrees C), who felt frozen and had no signs of life. Yet, when thawed, he revived. Thus, in the felicitous phrase of Dr. R. T Gregory, "No one is dead until warm and dead." 2 6

SOME RISK FACTORS: ALCOHOL, DRUGS, EXERCISE

The role of alcohol in hypothermia is controversial. On the one hand, it predisposes to hypothermia by several mechanisms: 1. It produces an increase in blood flow (and thus heat loss) near the skin ("cutaneous vasodilation"). Since the skin contains many temperature receptors, drinking alcohol generates a sensation of warmth, but this comes at the expense of internal heat; 2. Alcohol causes hypoglycemia (low blood sugar), which decreases the body's ability to produce heat; 3. As a central nervous system depressant, alcohol slows metabolism and promotes sleepiness; 4. A n d certainly alcohol impairs judgment, which may be critical under adverse conditions. Many hypothermia victims have blood alcohol concentrations (BAC) ranging from 0.13 to 0.25 gm/100 ml blood. "Legally impaired" in most of the United States is 0.08-0.10 gm/100 ml B A C . Since exercise also increases blood flow to the skin, the combination of alcohol with strenuous exercise would seem to cause maximum heat loss. On the other hand, alcohol appears to protect the heart against fibrillation (and has been used for that purpose during low-temperature medical operations, at levels of 0.40 gm/100 ml blood.) Perhaps this protective effect causes the observed higher survival rate in hypothermics who had been drinking, compared to those who were sober. 29

In addition, alcohol protects limbs against frostbite (freezing) by increasing their blood flow, but again, this is at the expense of core temperature. Some other drugs that have central nervous system depressant effects can also produce hypothermia, for example barbiturates, opiates, and the "major tranquilizer" chlorpromazine (Thorazine) and related compounds; but also some nonsedatives like acetaminophen (Tylenol) and lithium ion (used to treat manic-depressive behavior). These drugs interfere with temperature regulation at the hypothalamic regulatory center in the brain, and may cause hypothermia even at room temperatures. Of 103 consecutive

Suicide and Attempted Suicide • 371 Intensive Care Unit drug overdose admissions, twenty-seven were hypothermic. 32

SURVIVAL FACTORS 33

In the Swiss study of 234 cases of hypothermia, some of the factors that tended to be associated with the death of the victims were, in decreasing order of importance: (1) asphyxia (as would happen in an avalanche); (2) i n vasive rewarming methods; (3) slow rate of cooling. Positive survival factors were (1) fast cooling rate; (2) presence of ventricular fibrillation in cardiac arrest cases; (3) presence of alcohol and/or narcotics in the body.

WHAT ARE THE MEDICAL TREATMENTS FOR HYPOTHERMIA?

Treatment depends on the severity of the hypothermia, its underlying cause, and the age and general condition of the patient. In the mildest cases, warm, nonalcoholic drinks, food, and a few blankets are enough. If the hypothermia is moderate, or if the patient has low heat production due to exhaustion, illness, drugs, or malnutrition, more active warming is appropriate. This usually involves heating pads/blankets, hot water bottles, or other external sources of heat applied to the trunk. In wilderness situations, the best emergency rewarming may consist of sandwiching the (dried) hypothermic person in between two warm people, all inside or under a sleeping bag. In severe or acute hypothermia "active core rewarming" ( A C R ) is often used. There are many varieties of A C R . For example, heated liquids may be circulated around the stomach by a tube running through the nose, or heated IV fluids may be administered. In the most critical cases, those whose hearts have stopped, blood is often withdrawn from the femoral vein" (the largest vein in the leg, conveniently close to the surface near the groin), heated to 104 degrees F (40 degrees C) and oxygenated, and reinjected into the femoral artery. 34

How LONG DO PEOPLE SURVIVE UNDER COLD STRESS?

In one recent study, eight of eleven people with deep hypothermia and cardiac arrest were resuscitated. Five of the eleven had no heartbeat and six 35

372 • Geo Stone had ventricular fibrillation. None were breathing and all were clinically dead with wide, nonreactive pupils, and were supported by external heart massage and ventilation (CPR). The average (mean) length of exposure to the cold in the survivors was 4.4 hours, and average core temperature was 72.5 degrees F (22.5 degrees C ) . A l l three of the patients who died had also been asphyxiated (one in an avalanche, two in drownings).

COLD WATER

Data from shipwrecks and accidents suggest that a well-nourished man can survive roughly two hours in water at 39 degrees F (4 degrees C ) . At 32 degrees F (0 degrees C) survival time is only about a half an hour. Since swimming, like other exercise, increases heat loss (as well as heat production) due to increasing blood flow near the skin, this may account for some accidental "drownings" in cold water among good swimmers. On the other hand, at temperatures above around 68 degrees F (20 degrees C ) , fit swimmers can continue for many hours. Swimmers attempting the English Channel, which has summer water temperatures in the mid- to upper 50s F (13 to 15 degrees C ) , coat themselves with grease (more for insulation and to decrease water absorption than for buoyancy), and take hot drinks and quick-energy carbohydrate foods provided by their support boat every half hour or so. 3 6

However, if one is not exercising and taking in lots of calories, the same water temperature can be deadly: In March 1995, four U.S. Army Rangers died of hypothermia in Florida after spending several hours in water between 52 and 59 degrees F (11 to 15 degrees C) while training. Similarly, a man died of hypothermia after getting stuck in the mud of a 15-foot-diameter pond, which was no more than 3 feet deep. A i r temperature was 70 degrees F (21 degrees C) and water temperature was 52 degrees F (11.5 degrees C). Even warm (for example, 95 degrees F, or 35 degrees C) water will chill you after an hour or so unless you are actively exercising. As always, there is substantial variability between people. For example, the lowest temperature water in which different young men and women at rest could maintain a steady body temperature ranged from below 53.6 degrees F (12 degrees C) to 89.6 degrees F (32 degrees C ) . This depended on both 38

Suicide and Attempted Suicide • 3 7 3 insulation (primarily thickness of the fat layer on the trunk of the body) and metabolic heat production. Each of these factors was about equally important: Fast metabolizers could maintain body temperature in water 18 degrees F (10 degrees C) colder than slow metabolizers who had the same amount of body fat. 39

COLD AIR

Immersion in cold water seems to cause loss of body heat about twentyfive to thirty times as fast as air at the same temperature. As a result, survival time in cold air is much longer than in water of the same temperature. Consequently, secondary factors, such as wind speed, precipitation, and amount and type of clothing worn, are more important in cold air than in cold water. 40

COLD COMFORT: HOW TO DO IT

Make arrangements so you won't be looked for: for example, tell people you're going away for a few days. Go to a cold, secluded spot where you won't be seen. Drink alcohol and/or take sedatives. You can speed up the process by removing clothing and/or getting wet. Obviously, the amount of time needed will also be very dependent on temperature and wind conditions, and your size, weight, and fat content. These are too many variables to make even rough time estimates. Use of a home freezer has been recommended, but the air supply in such freezers is so limited that asphyxia will occur long before hypothermia. Commercial freezers are a possibility, but the risk of untimely discovery must be considered. IN WATER. Since heat loss in water is much faster than in air of the same temperature, the amount of time that one is subject to being saved is correspondingly diminished. The main concern will be to avoid being seen, both to avoid unwanted rescue and to prevent risk to potential rescuers. Depending on the temperature of the water and your physical condition, fatal hypothermia can occur in as little as thirty minutes or so; less after alcohol and/or sedatives. Be aware that unless the water is very shallow (and even ON LAND.

41

then if you end up facedown), you are likely to actually die of drowning while insensible from cold, rather than from hypothermia.

SUMMARY

Hypothermia is an underappreciated means of suicide: It is relatively painless, though certainly uncomfortable, and generally fatal if not interrupted. The main disadvantage is that it normally takes several hours on land (but much less in water), during which time permanent injury is quite possible if rescue occurs. A second major disadvantage is that hypothermia as a means of suicide is limited by climate and season. As a suicidal gesture, hypothermia is a bad choice, because the length of time is so dependent on both weather and individual variables. A n d while, in principle, you can change your mind, in practice you lose too much capacity to think and/or act rationally when hypothermic for this to be a reliable survival net.

Usually fatal, with a high enough jump site Some contemplation time on the way down Can't do much about it once you're in the air Not reliably lethal for jumps of less than 150 feet High incidence of permanent injury Risk of injuring others Fear of heights is common

Jumps from higher than 150 feet (ten to twelve stories high) over land and 250 feet over water are almost always fatal; however, most suicide attempts are made from considerably lower heights. The consequences of lower jumps 376

Suicide and Attempted Suicide • 3 7 7 are unpredictable. Permanent injuries, including paralysis, are common. Jumping is thus a particularly bad choice for a suicidal gesture. There is about a fifty-fifty chance of surviving a one-story (12 foot) fall if you land on your head; three to four stories if you land on your side; four to five stories if you land on your feet. 2

The word "jumper" was apparently used in the Codebook of Federal Security Agencies to describe someone attempting suicide by jumping from a height. The term has commonly come to include accidental and homicidal high falls, which is how we'll use it. The two major questions a potential jumper might want answered are: 3

• Is jumping a reliable way to kill yourself? The short answer is that it's about 95 to 98 percent lethal if you fall more than 150 feet (ten to twelve stories) over land—but sometimes a much shorter fall is fatal (2.5 feet in one case). • What are the risks of long-term injury among those surviving a fall? Short answer: quite high; more than half the survivors in one study were either still hospitalized or permanently unable to work a year after their jump. 4

We'll look later at the available data in order to answer these questions in greater detail.

In four smaller samples the percentage of suicides due to jumping were 8 percent in Leeds, England (I960), 6 percent in (the American state of) Georgia (1975 through 1984) , approximately 5 percent in Finland, and around 3 percent in Australia.

WHAT ARE THE CHARACTERISTICS OF SUICIDAL JUMPERS?

I've found only one detailed, recent study of suicidal jumps (other sources combine accidental and unknown-cause falls, or have other limitations, for our purposes). This report is from Finland, and gives us some interesting information about the jumpers, their injuries, and their situation a year later. Between 1982 and 1984, eighty known suicidal jumpers were brought to the University Center Hospital in Helsinki, Finland. Twenty (25 percent) of these people died; 7 were dead-on-arrival ( D O A ) or within an hour, and 13 died while in the hospital, 12 of these within twenty-four hours. This death rate of 13 in 73 (18 percent) for those alive on reaching the hospital is similar to the 17 percent reported in the most comparable American study. However, how many were dead at the scene (DAS) was not reported. THE JUMPERS. Some of the characteristics of these Finnish jumpers follow: 9

• Age range was 15 to 65 years, with an average (mean) of 29.8 • 40 percent (29 of 73) were female • The average (median) hospital stay was forty-nine days

These figures are similar to U.S. data shown later in this chapter. HEIGHT OF FALLS. Interestingly, 40 percent fell between 16 and 26 feet (5 to 8 meters), or two to three stories; 38 percent between 26 and 40 feet (8 to 12 meters); 22 percent from higher than 40 feet (12 meters). I'm surprised that so many people intending suicide would jump from such low heights. This suggests impulsive, impaired, ignorant, or irrational decisions in many of these jumps. b

A minor curiosity is that monthly distribution of suicidally intentioned jumps in Finland is similar to that from Seattle and New York, but different from overall suicides in Finland and elsewhere. The peaks of jumping occur in the fall; overall suicides in spring and summer. In Australia, the suicide peak is also in the springtime, which is September through November in the southern hemisphere. MONTHLY DISTRIBUTION OF JUMPS.

380 • Geo Stone SURVIVOR'S OUTCOMES.

One year later:

• 19 of 53 (36 percent) had gone back to work • 20 of 53 (38 percent) were out of hospital, but physically unable to work ("permanently pensioned") • 9 of 53 (17 percent) were considered mentally unable to work, mostly from preexisting conditions ("permanently pensioned") • 12 of 53 (23 percent) were still institutionalized, of whom 8 (15 percent) were completely paraplegic (paralyzed throughout the lower half of their bodies) In thinking about these outcomes, remember that the numbers do not include people dead at the scene or dead on arrival. Less detailed, but more recent, data from Scotland show somewhat lower survival rates than those from Finland. This is probably because the canny Scots jumped from greater heights: 40 percent jumped from higher than four floors. Also, while about half the jumpers (28 of 58) touched down head first, all eight who jumped from higher than the thirteenth floor landed on their heads, though at such heights, it wouldn't have mattered: The highest survivor (on land) jumped from the fifth floor. About half of the jumpers (31 of 58) got to hospital alive; 35 percent (11 of 31) of these later died, giving a total fatality rate of 66 percent (38 of 58). 14

U.S. DATA

Data on suicidal jumpers from the United States are less informative: Local surveys tend to combine suicide and accident data, and there are no detailed national data. Nevertheless, it's all we have. In a frequently cited study from New York in 1965, we get some interesting, if noncurrent, numbers. In 1963, there were 748 deaths from falls in New York City. Two hundred ninety (39 percent) were suicides, and 458 (61 percent) "accidental." Of fifty-three of these people, whose falls were three or more stories and who were brought to Harlem Hospital, twenty-two (41.5 percent) survived, despite major multiple-organ injuries. Age, sex, and circumstance distribution are shown in Table 25.3. 15

From a larger and somewhat more recent study, we get generally similar age/gender distribution (Table 25.4). However, the percentage of deaths is much higher in the earlier group because: (1) the Harlem Hospital data excluded jumps from less than three stories; and (2) included those dead on arrival and dead at the scene.

In both studies these falls were more lethal to the youngest and oldest jumpers' group, and there were substantially more male than female jumpers. Since about three-quarters of dead jumpers die before getting to the hospital, and 34 of 200 (above) died after being hospitalized, we can make a rough calculation that about 45 percent of suicidal jumps are fatal. This is quite consistent with other U.S. data. An oddity in the data from the Bronx is that only 6 to 7.5 percent of the jumps were described as "suicidal," a much smaller percentage than the 20 to 45 percent generally cited elsewhere. Lewis felt that more of his patients had actually attempted suicide than are reflected in his numbers, because (1) 17

18

19

Suicide and Attempted Suicide • 383 a witness or a suicide note was required for a suicide verdict when the jumper was dead, and (2) the social and religious stigma attached to suicide discouraged survivors from admitting their intent. These latter factors might be even more significant in Reynolds's Catholic hospital. In Lewis's study, 75 percent of the female, but only 54 percent of the male jumpers died. This surprising gender distribution of lethal falls is consistent with the notion of women being the weaker sex, but is better explained by the fact that the average height of the females' falls was greater than the male ones (6.3 stories versus 5.2 stories). Racial distribution of jumpers was representative of the area's population: 46 blacks, 7 whites. One might have expected the suicidal jumpers to have a higher death rate than those who fell by accident, since, presumably, those intending suicide would make a point of jumping from what they considered a sufficiently lethal height. The numbers don't bear this out: Suicidal jumpers died at about the same rate (56 percent), as those who fell accidentally (63 percent). As in Finland, many suicidal jumpers in the United States seem to be either unaware of how survivable their jumps are or are not rational when they jump. In Austria, on the other hand, suicidal jumpers fell from almost twice the average height as accidental jumpers. Two other possible explanation for the observed similarity in death rates are: (1) The apartment buildings in Harlem are mostly five or six floors high, making it difficult to climb higher for a deliberate fall than for an accidental one; (2) more suicidal than accidental jumpers leap from lethal heights. They would more likely be dead at the scene, and thus ineligible to take part in Lewis's study of hospitalized jumpers. Of the 53 jumpers, six (11 percent) had a known history of treatment for mental illness, and one-third were alcoholics. On autopsy, 7 of 11 had brain alcohol levels of 0.10 percent (0.10 grams alcohol per 100 grams tissue) or more. A level of 0.08-0.10 percent is "legally intoxicated" in the United States, but such a level wouldn't much impair a chronic alcoholic, so the significance of this finding is unclear. 20

384 • Geo Stone How DANGEROUS IS JUMPING COMPARED TO OTHER METHODS OF ATTEMPTED SUICIDE?

The data in Table 16.1 show that suicidal jumping injuries fall into the middle group in lethality, with a death rate of 42 percent. Since minor injuries tend to be underreported, the actual fatality rates are lower than the figures cited. WHAT DO WE KNOW ABOUT FATAL-FALL INJURY? 21

HEIGHTS AND CIRCUMSTANCES OF FATAL FALLS. The heights of the fatal falls in this series ranged from 2.5 feet (brain injury) to 170 feet (severe multiple organ injury). One hundred eleven (76 percent) were dead at the scene or on arrival at the hospital; 35 (24 percent) lived for lengths of time ranging between 3 hours and 120 days. Twenty-five percent were suicides, 57 percent accidents, and 18 percent undetermined. AGE RANGE AND SEX DISTRIBUTION AMONG JUMPERS. The youngest fatality was eighteen months old, a child who fell from a fourth-story window; oldest was a ninety-two-year-old man who fell from a first-floor window. The ratio of males to females was 108 (74 percent) to 38 (26 percent), roughly 3:1. This is similar to male/female ratios reported elsewhere. PHYSICAL AND MENTAL ILLNESS AMONG SUICIDAL JUMPERS.

The medical problems of some of the suicides with physical illnesses were quite serious: Three had probably terminal cancer, one had had a heart attack, one was a "respiratory cripple." The other four had problems that, apparently had not been fully diagnosed and may have been treatable; two had enlarged prostates and couldn't pass urine, one was coughing up blood, and one had severe abdominal pain. A l l of these people jumped from hospital windows, the abdominal pain patient pulling out IV lines in order to do so. Apparently, he was not given adequate pain medication. ACCIDENTAL FALLS. The eighty-three victims of accidents included thirty-five who fell at work, typically while constructing, demolishing, repairing, or cleaning buildings. One stunt man managed to kill himself by landing on his head when he jumped from a ladder onto a mattress. Nineteen (one woman, eighteen men) died while working on their own or on a friend's house. Eight of these men fell while cleaning windows, as did the sole woman. The twenty-nine miscellaneous accidental falls included eleven from a window or balcony, and one each from a table and from a kitchen draining board. One person was killed by jumping from a first-floor window to escape a fire, and one from a first-floor window to escape police.

WHAT IS THE NATURE AND SITE OF THE INJURIES IN FATAL FALLS

AND JUMPS?

In about 85 percent of these cases, the part of the body the victim landed on could be established by witnesses or the nature of the injuries and the position of the body. HEAD IMPACT. Sixty-six (45 percent of total) of these people fell on their heads. In only four cases was the skull not fractured, and in three of these four there was brain damage, anyhow. The skull sustained the only fracture in thirty-one of these sixty-six deaths. BUTTOCKS IMPACT. Eleven (7.5 percent of total) landed on their buttocks, i n cluding one who was impaled on a wooden railing. In addition to 4 skull fractures (36 percent), there were 5 spinal fractures (45 percent), and 9 pelvic fractures (82 percent). Organ damage included brain hemorrhage (6 cases), liver laceration (4 cases), heart laceration (3 cases), ruptured aorta (main artery from heart) (2 cases), and ruptured spleen (1 case). LOWER LIMB IMPACT. Twenty-one (14 percent of total) landed on their feet or knees. Nine had skull fractures despite landing vertically, and of those without skull damage (12 or 13; the text and data numbers don't match again), 9 had brain injuries, mostly hemorrhages. Fourteen of the 21 broke both legs; 5 broke one leg; 2 broke neither. There were 4 spinal fractures. SIDE OF BODY IMPACT. O f the 25 (17 percent of total) people in this group, 7 had skull fractures, 5 had broken backs, 2 had a ruptured heart, 1 a lacerated liver, and 1 a lacerated kidney and spleen. Most of the deaths were due to shock and blood loss from multiple fractures. Brain injury was found in 72 percent (105 of 146) of the victims, and 97 percent (64 of 66) of those who landed on their heads. Brain hemorrhage was the most frequent finding and was generally fatal, independent of additional wounds. Brain damage, while almost certain when a jumper landed on his/her head, was also common (51 percent) when there was a different impact site. Interestingly, the extent of brain injury was not proportional to the height of the fall: Of 23 falls between 50 and 170 feet, 13 (57 percent) had brain damage, while 30 of 38 (79 percent) falls from the first floor (less than 15 feet) showed such injury. Two fatalities from falls of less than 4 feet were due to brain injury. The reason(s) for this lack of proportionality are not certain, but possibly

Suicide and Attempted Suicide • 387 (1) in higher falls, people have enough time to orient themselves to avoid hitting head first; (2) this is a study of fatal injuries: People with short falls who did not land on their heads are unlikely to die; thus the data are skewed toward finding more head injuries in short falls because they were fatal. There were 32 heart injuries, of which 24 were considered to be the cause of death. These included 4 fractures of the heart and 8 tears of the sac surrounding the heart, the pericardium. Unlike the case with head injuries, the incidence of other injuries was roughly proportional to the height of the fall. The liver was the most height-sensitive abdominal organ: In falls of more than 50 feet, 43 percent of the jumpers had liver lacerations; in shorter falls, this was only 4 percent.

WHAT IS THE RELATIONSHIP BETWEEN HEIGHT OF FALL AND SEVERITY OF INJURY?

The data in the previous section describe injuries from fatal falls; what about those that were survived? The severity of non-head injuries roughly corresponds to the height of the fall, but there are often exceptions and a wide range of injury is seen from similar-height jumps: the lowest (9) and highest (66) ISS scores were both found in 8 to 12 meter (26 to 39 foot) falls. Some people survive much more severe injury than do others (one survived an ISS 58; another died from ISS 28). As we might expect, there is a correlation between how far someone falls and the likelihood of their dying, but the association is not as clear as one might suppose. Three studies from the United States provide some information on the relationship between height of the fall, survivability of urban falls/jumps, and the length of subsequent hospitalization. In the most recent, from Brooklyn, 161 adult jumpers who lived long enough to get out of the emergency room were studied. Thus those dead at the scene or on arrival, or shortly afterwards, were not included. Each had fallen between one and seven stories, which were around 12 (newer buildings) to 15 (older buildings) feet per story. The age range was 13 to 74 years with an average (mean) of 31.7. Twentythree percent were female and 77 percent male. In the half of the cases where the circumstances were known, roughly 40 percent were attempted suicides, e

22

388 • Geo Stone 50 percent accidents and 5 percent crime-related. The length of the hospitalization ranged from 1 to 120 days, with an average (mean) of 28.5 days. Putting this in table form and comparing it to earlier studies: Table 25.6 Relationship of Hospitalization Time, Deaths/ and Height of Fall

* F r o m the death rates, it appears that medical care improved from 1965 to 1986. H o w even these studies are not directly comparable because Lewis includes only third-story and above jumpers in his data, while Scalea excludes those dead at the scene, dead on arrival, or dead before getting out of the emergency room.

What I find most striking in these data is the fact that such a large number (40 of 72) of jumpers survived fifth-floor and higher falls. The authors point out that these urban falls might be different from falls into water or in a rural setting; those who jump or fall from buildings may hit fire escapes or other projections, and can land on a number of possibly yielding surfaces: car roofs, soil, awnings, garbage piles, and pedestrians, among others. There was a wide range of severe injuries to all parts of the body (Table 25.7). The most common was fracture: 79 percent of Scalea's patients had at least one major fracture (spine, pelvis, or long bone of arm or leg). While this was almost invariably true for falls of four or more stories (48 of 49 or 98 percent), even one-story falls had a significant number of such injuries. The overall survival rate was 95 percent (154 of 161) for those who made it out of the emergency room. Table 25.7 (Scalea, 1986) Distribution of Bone Fractures by Height of Jump

390 • Geo Stone Eleven of the twenty-eight (39 percent) with major spinal fracture had "neurological deficits": One had partial paralysis of all four limbs, one partial paralysis of the lower half of the body and the others complete paralysis of the lower half of the body. This is not exactly a desirable outcome whether you're trying to kill yourself or you intend a suicidal gesture. CASE REPORTS. A few unusual case report summaries may be of interest. 8

1. Landing in deep snow, if you can arrange it, is probably your best bet for surviving a long fall or jump. A twenty-one-year-old man jumped from seventeen stories and hit in a snowbank. He lived, but both legs had to be amputated. Another survived a 35,000 foot (almost 6.6 mile; 10.7 km) fall from an airplane. 23

2. In another case, an eighteen-year-old jumped or fell from a fifthfloor roof. It had been raining so heavily that he sank one and a half feet into the soil and was uninjured. 24

3. A fifteen-year-old fell out of a silo into a pile of dried cow manure. He bounced and landed on his side, breaking his wrist in the second fall. 4. A forty-year-old "committed infanticide and then attempted suicide, jumping a distance of 44'5" from the roof of a tenement. He landed, barefoot, on a granite block. . . . His only injuries were a minimal fracture of the right pubic ramus and of a cervical vertebrae. He remained conscious after impacting and wandered off.... Police at first refused to believe that he had jumped." 25

A DIGRESSION After all this hard reading you deserve a break. The following cautionary tale is quoted from John W. Watts: At the 1994 annual awards dinner given by the American Association for Forensic Science, A A F S President Don Harper Mills astounded his audience in San Diego with the legal complications of a bizarre death. Here is the story. On 23 March 1994, the medical examiner viewed the body of Ronald Opus and concluded that he

Suicide and Attempted Suicide • 391 died from a shotgun wound to the head. The decedent [about to turn twenty-one years old] had jumped from the top of a tenstory building intending to commit suicide. (He left a note indicating his despondency.) As he fell past the ninth floor; his life was interrupted by a shotgun blast through a window, which killed him instantly. Neither the shooter nor the decedent was aware that a safety net had been erected at the eighth floor level to protect some window washers and that Opus would not have been able to complete his suicide anyway because of this. Ordinarily, Dr. Mills continued, a person who sets out to commit suicide ultimately succeeds, even though the mechanism might not be what he intended. That Opus was shot on the way to certain death nine stories below probably would not have changed his mode of death from suicide to homicide. But the fact that his suicidal intent would not have been successful caused the medical examiner to feel that he had a homicide on his hands. The room on the ninth floor whence the shotgun blast emanated was occupied by an elderly man and his wife.They were arguing and he was threatening her with the shotgun. He was so upset that, when he pulled the trigger; he completely missed his wife and the pellets went through a window striking Opus. W h e n one intends to kill subject A but kills subject B in the attempt, one is guilty of the murder of subject B. W h e n confronted with this charge, the old man and his wife were both adamant that neither knew that the shotgun was loaded.The old man said it was his long-standing habit to threaten his wife with the unloaded shotgun. He had no intention of murdering her; therefore, the killing of Opus appeared to be an accident. That is, the gun had been accidentally loaded.The continuing investigation turned up a witness who saw the old couple's son loading the shotgun approximately six weeks prior to the fatal incident. It transpired that the old lady had cut off her son's financial support and the son, knowing the propensity of his father to use the shotgun threateningly, loaded the gun with the expectation that his father would shoot his mother. The case now becomes one of murder on the part of the son for the death of Ronald Opus.

392 • Geo Stone There was another twist. Further investigation revealed that the son had become increasingly despondent over the failure of his attempt to engineer his mother's murder This led him to jump off a ten-story building on March 23, only to be killed by a shotgun blast through a ninth-story window. The medical examiner closed the case as a suicide. 'The son had also been something of a musician and composer He left his final composition on the windowsill, appropriately in the key of A-flat minor and titled "Opus Posthumous."

IMPACT WITH WATER 11

It was the Golden Gate Bridge or nothing.

— A survivor Thus far the discussion has been limited to falling on land. Leaping from bridges or cliffs into water is a bit different and is often considered more romantic. The results are, however, similar. The Golden Gate Bridge is to suicide what Niagara Falls is to honeymoons: The most popular site in North America. Joseph Strauss, the chief engineer during the bridge's construction, predicted that his masterpiece would be "practically suicide-proof." He was a considerably better bridge builder than seer: Between the opening of the bridge in 1937 (when ten workers fell simultaneously to their deaths) and 1990, 885 people are known to have leaped from Golden Gate; the actual number, including those neither seen nor recovered, is certainly higher. In addition, eighty-seven people "accidentally" fell from this bridge between 1937 and 1963. This is a particularly lethal bridge as well, with only nineteen of the 885-plus (less than 2 percent) living to tell about it. 1

One August day in 1937, H. B. Wobber a forty-nine-year-old bargeman, took a bus to the Golden Gate Bridge, paid his way through the pedestrian turnstile, and began to walk across the mile-long span. He was accompanied by a tourist he had met on the bus, Professor Lewis Naylor of Trinity College in Connecticut. They had strolled across the bridge which stretches in a single arch

Suicide and Attempted Suicide • 3 9 3 from San Francisco to the hills of Marin County, and were on their way back when W o b b e r tossed his coat and vest to Professor Naylor. "This is where I get off," he said quietly. "I'm going to jump." As W o b b e r climbed over the four-foot railing, the professor managed to grab his belt, but W o b b e r pulled free and leaped to his death. 30

This was the first known suicide from the bridge, and took place three months after its opening. Golden Gate soars 250 feet (76 meters) above water at mid span. This is rail-to-water distance. There is no significant barrier; most people can easily step over the four-foot-high railing. A proposal to erect a suicide-preventing fence was opposed by a two-to-one majority in San Francisco and rejected by the bridge district's board of directors as unaesthetic. Instead, "crisis phones" were installed, so that potential jumpers who wanted to talk things over could do so. No report as to how often they're used. The impact velocity of an average body jumping this distance is around 74 miles per hour, and fall time is around four seconds. One might expect water to be a more forgiving surface to fall on than concrete or asphalt, and it is, but at these speeds the difference is about as important as whether a bug is squashed by a car or by a truck: The distinction is academic. A study of one hundred consecutive autopsies of Golden Gate jumpers found 44 percent female, 56 percent male. Age range was 15 to 86 years, with an average (mean) of 31.5 years; 97 percent were white, 2 percent black, and 1 percent Asian (spurring claims of racial discrimination and a short-lived demand for affirmative action by the California legislature). 31

The San Francisco Public Library keeps a file of old newspaper clippings on Golden Gate Bridge suicides. Most people get squibs; more columninches are devoted to the "rich or famous, the oldest (87) or youngest (5), or those leaving the strangest notes. (One person left this explanation: ' A b solutely no reason, except I have a toothache'.)" The official one-hundredth fatal jump took place in 1948. Fortunato A n guiano, a fifty-three-year-old dishwasher left a note saying, "Just bury me in my own land, the one you people take away from us." After official number 499 in 1973, ghoulish TV stations (is this redunm

35

3 9 4 • Geo Stone dant?) set up twenty-four-hour-a-day cameras hoping to catch the numerologically significant number 500 on film. Police patrols were increased. The first fourteen applicants for the role (one wearing a T-shirt bearing the number 500) were all stopped or talked out of jumping, but number fifteen, twenty-six-year-old Steven Houg, evaded rescuers and leaped to his death. The cameras missed it. In June 1995, as the official number approached one thousand, similar charming media and popular behavior reappeared; for example, a radio station offered a case of Snapple (any flavor) to the family of number one thousand. Since the California Highway Patrol stopped public reporting of jumpers after 997,1 don't know if they ever paid up. 36

TYPES OF INJURY

Golden Gate jumpers show similar injuries to people hitting land: broken bones, shattered organs, torn veins and arteries. The distribution of these i n juries differs from land falls, however: There are many more fatal chest injuries and fewer head traumas and bone fractures. 37

CHEST AREA. Bleeding into the chest cavity was found in 82 percent, and lung damage in 87 percent of Golden Gate jumpers. These injuries occurred about three times as often as in fatal urban falls in London. Injury to the heart area occurred in around 20 percent of these jumps, and was often associated with broken ribs. 38

39

Liver and spleen laceration were the two most frequently damaged abdominal organs. This is similar to falls from above 50 feet on dry land. Abdominal bleeding was seen in 84 percent of the bodies (abdominal or chest bleeding is often a fatal injury because some of the largest blood vessels are found in this region). There was one case of shark mutilation: A young woman was pulled in with the entire abdominal wall and gastrointestinal tract missing, after forty-five minutes in the water. SKELETAL. Forty-two percent of Golden Gate jumpers had broken bones (other than ribs and sternum), significantly fewer than in land falls. Nine percent had skull fractures and 3 percent spinal cord transections compared to 59 percent and 7 percent respectively, on land. What's happening here is that the impact velocity of around 75 miles per hour is much greater ABDOMEN.

As a result, the mechanical strength of bone is less likely to be exceeded (fewer broken bones), but that of organs/tissues more likely exceeded, causing them to be fractured or torn away from their major blood vessels. SURVIVORS. O f 6 initial survivors, 3 had pneumothorax (air in the chest cavity, preventing inflation of lungs); 3 required removal of their spleens; 2 had fractured livers; 4 had at least one compression spinal fracture (spine compressed after entering water feet or head first).

CASE REPORTS

42

On 27 August 1980, a thirty-four-year-old West German stuntman known as Kid Courage, dressed in wetsuit, water ski jacket, flotation vest, and boxing shoes, [and with] his wrists, and ankles, stomach and chest taped, leaped from the Golden Gate Bridge in an attempt to establish a free-fall record. One witness observed that, after jumping, "he was trying to get his feet down but never made it and hit flat on his back." Another witness, an expert diver; suggested that the 15- to 20-knot wind might have been a factor in his instability while falling. The jumper was lifeless when pulled from the water by colleagues who had watched the spectacle from below. On autopsy he was found to have multiple spinal fractures and transection of the spinal chord. In addition, there were severe lacerations of the liver, spleen, and lungs. "Any one of these injuries would have proved fatal." Divers in Acapulco jump several times a day from 135-foot-high cliffs. This corresponds to hitting the water at about 60 miles per hour. W i t h perfect entry into the water—arms rigidly extended and thumbs locked—they show little evidence of chronic damage even after many years of diving. Perhaps they don't dive when it's windy. 43

44

Entering feet first is second-best. An "almost perfect" feet-first entry from Golden Gate Bridge still resulted in three spinal compression fractures in an otherwise uninjured seventeen-year-old jumper. 45

OTHER BRIDGES

It seems reasonable to expect that bridges lower than Golden Gate will be less lethal, and this is the case. For example, four bridges in Denmark, which average 40 meters (130 feet) above water, have a jumper-survival rate estimated to be around 25 percent and a majority of the deaths are attributed to drowning, rather than trauma. The reason these Danish jumpers were studied is interesting. It goes back to 1974. In that year a Danish husband was accused of strangling his wife and tossing her over a 28 meter (92 foot) bridge into water. At autopsy, among other findings, there were fractures of her jaw, cheek, nose, and thyroid cartilage. The question of whether or not these injuries could be the result of a 28 meter fall into water was obviously critical, but apparently nobody knew the answer and the man was acquitted. The courts recommended the production of reference materials on this topic, which was done using undisputed suicides. In none of the ten cases autopsied, with jumps of between 35 to 51 meters (114 to 167 feet), were there any injuries of the face, jaw, or neck organs. 46

OTHER JUMPS

Perhaps the second-most-famous jump site in the world is the M t . M i hara volcano in Japan. In January 1933, a girl jumped to her death there. The next month another girl from the same school did the same. A legend soon arose that they were instantly cremated and their souls went straight to heaven in a plume of smoke. On a single day in April, six people jumped and twenty-five more were forcibly prevented from doing so. By the end of 1933, there were 133 known suicides and an unknown, but large, number of others were suspected. Despite police efforts (including prohibition on sale of one-way ferry tickets to the volcano's island), there were 619 confirmed jumps in 1936 alone, but suicides here didn't stop until 1955, when a badly injured couple who had jumped were rescued from inside the crater. This destroyed the illusion of jiffy cremation and, apparently, the allure of the vol47

FALLS FROM EXTREME HEIGHTS

Due to friction with air, a human body reaches a constant (appropriately called "terminal") velocity of around 120 miles per hour (54 meters, or 60 yards, per second) after falling approximately 480 feet (35 to 40 stories). Thus, if it's any consolation, you won't hit any harder from a 20,000 foot fall than from 500, though you will have a longer trip. Terminal velocity varies, and can be significantly changed by choice of clothing and the position assumed during the fall: Vertical, with good dive form is fastest, around 185 mph; horizontal, with limbs spread is slowest, 120 mph. For example, in 1885 twenty-four-year-old Sarah Henley jumped from the Clifton suspension bridge, a 250-foot-high structure in Bristol, England. According to the Guinness Book of World Records, her "voluminous dress and petticoat acted as a parachute," and she landed in the mud, merely "bruised and bedraggled." This feat (sans dress and petticoat) was recently matched by an eighteen-year-old male. He described seeing himself as a detached observer, the fall as pleasurable, and time passing slowly. Correcting for air resistance, we have impact velocities as follows: 48

However, one study found that injuries and deaths were not well-correlated with either the height of the fall or the nature of the surface landed on: "In the past two years at least ninety persons have survived falls of 100 to 900 feet, and nine have survived falls of over 1,000 feet" and concludes 53

398 • Geo Stone that "some individuals survive free-falls terminating on nonyielding rigid structures at exceedingly large magnitudes of force with minor injury or, occasionally, with no apparent clinical trauma." Interesting, if true. While the author makes some speculations, the reason(s) these high falls are survived is not known. These extreme falls are usually jumps from airplanes. One person survived for twelve hours after a seven-mile (around four-minute) fall. Of twelve people who survived falls of more than 100 feet, ten landed on their feet. Since feet have a smaller area than does the torso, the impact pressure (force per area) is greater, but this is apparently more than offset by the structural strength of the vertical bones and muscles. However, these cases are interesting and turn up in medical journals because they are unusual; death is almost always the result of a fall of this magnitude. 54

SUMMARY

Suicidal jumps from higher than approximately 150 feet (10 to 12 stories) on land and 250 feet over water are about 95 to 98 percent fatal. However, a majority of jumps on land are between 20 and 50 feet. These shorter jumps are a crap shoot and often cause permanent injury, possibly paralysis and brain damage. Other than the view, there are better ways to go.

T h e Injury Severity S c o r e (ISS) is a widely used quantitative measure of the n u m b e r and

severity of injuries. An alternative explanation f o r the discrepancy b e t w e e n t h e ISS and jump survival is that the ISS is n o t a v e r y g o o d gauge of lethality. It has been criticized f o r generating higher severity s c o r e s f o r multiple m o d e r a t e l y serious injuries than f o r a single critical one. f

ln Scalea's patients, death was due to massive internal bleeding (three cases; o n e p e r s o n

died despite receiving 20 units of b l o o d in an h o u r ) ; head injury (two cases); infection after internal bleeding (one case); unexplained cardiac arrest (heart s t o p p e d , o n e case); and u n recognized tracheal stenosis (narrowing of w i n d p i p e , presumably due to injury, o n e case). Similarly, Lewis cited brain and chest damage, and abdominal bleeding as cause of death. In Reynolds's study, 30 of the 34 dead had skull fractures, s o m e t i m e s in addition to o t h e r d a m age; brain t r a u m a was the m o s t c o m m o n fatal injury. g

l n case y o u haven't thought it t h r o u g h , c o m p l e t e paralysis may mean (depending on the

site of the spinal damage) that y o u will be essentially helpless f o r the rest of y o u r life: fed by s o m e o n e else; reliant o n s o m e o n e t o change y o u r diaper (no voluntary muscle c o n t r o l ) ; strapped into a wheelchair like a sack of p o t a t o e s ; prey to r e c u r r e n t infections; and subject to pressure s o r e s on y o u r back, buttocks, and legs, because y o u can't m o v e a r o u n d . h

A c c o r d i n g t o the C a l i f o r n i a Highway Patrol and bridge w o r k e r s , a b o u t t w o - t h i r d s o f p o -

tential jumpers are talked o u t of it, and of t h e s e , apparently v e r y few go on to kill themselves by o t h e r means (New York Times, July 9, 1995). In o n e (perhaps apochryphal) instance, a p o liceman is said to have s h o u t e d , " C o m e d o w n or I'll s h o o t ! " to a w o u l d - b e jumper, w h o o b e diently climbed d o w n . i

In the 1930s and '40s sixteen p e o p l e died f r o m jumps off t h e E m p i r e State Building, but

this pretty m u c h e n d e d with the e r e c t i o n of a fence a r o u n d the o b s e r v a t i o n tower. G o l d e n G a t e is preferred to the Bay Bridge (which c o n n e c t s San F r a n c i s c o to the East Bay) by m o r e than five to o n e despite similarities: a b o u t the same height, o p e n e d within m o n t h s of each other, and near each other. Bay Bridge doesn't have pedestrian walkways; nevertheless, a b o u t t h r e e times as many car drivers j u m p e d f r o m G o l d e n G a t e . Indeed, as many East Bay drivers j u m p e d f r o m G o l d e n G a t e (fifty-eight) as f r o m Bay Bridge (fifty-seven) (Seiden, j

1983-1984).

A r e v e r s e - p s y c h o l o g y a p p r o a c h has also b e e n suggested: installing a diving b o a r d , with a

nearby h o o k f o r hanging one's c o a t and a mailbox for the c o n v e n i e n t d e p o s i t of suicide notes. k

l n 1977, t h e bridge's 40th anniversary, a rally was held by p r o - b a r r i e r activists. O n e of the

speakers said, "It is entirely fitting that on M e m o r i a l D a y we are h e r e on a c c o u n t of the h u n dreds of p e o p l e w h o are n o t casualties of war, but casualties of society . . . in t h e final analysis, we have to bear collective responsibility f o r t h o s e individuals w h o c o u l d n o t find a place

1979]

W h i l e that piece of legislation is bogus, t h e r e was a presumably serious attempt to make

it against the law to c o m m i t suicide by jumping f r o m the bridge ( N e w Y o r k T i m e s , J u l y 9,1995). T h e effectiveness of such legislation is o p e n to q u e s t i o n . m

AFTERWORD, OR WHERE DO WE GO FROM HERE?

As of this writing, the central legal, legislative, and ethical suicide issue in the United States is physician-assisted suicide (PAS). PAS is the most reliable and least traumatic approach to suicide, and has been carried out since at least the time of the early Greeks. (Hippocrates' Oath was partly in response to this practice.) The current ethical arguments, for and against it, were laid out in the early 1870s and have changed remarkably little. Meanwhile, medical ability to prolong dying has increased to the point where the public is often more afraid of dying than of death. This is the driving force for legalization of assisted suicide. 3

The ethical situation is not entirely clear-cut in PAS; both sides have valid points. Under the circumstances, there is really no way of knowing if opponents' fears will come to pass. Thus, the ongoing experience with PAS in Oregon will be of great importance, and should answer some of the questions of potential abuse. The three-decade-long history of PAS in the Netherlands is also generally reassuring, though the differences between Dutch and American society makes extrapolations tentative. I do not expect many of the already decided to change their position quickly as a result of the information from Oregon starting to trickle in; people are quite capable of reaching divergent conclusions from the same data. The debate will continue, as it should; but we will at last, have some facts and evidence to guide us.

Suicide and Attempted Suicide • 4 5 3 SOME SUICIDE RESOURCES: HOTLINES AND THE INTERNET

Because of space limitations I have posted the drug appendix on my web site. The following are other sources for similar information, both paper and electronic (Web): A widely available toxicology handbook is Robert H. Dreisbach, Handbook of Poisoning: Prevention, Diagnosis, and Treatment 12th ed. (Lange, Los Altos). 1987. It's laid out for quick and clear reference and provides toxicity data, but is written for people who already have a reasonable knowledge of drugs and poisons. Consumer Reports annually publishes Drug Information for the Consumer which provides understandable information on over 5,000 drugs: uses for particular drugs; generic and trade names; related drugs; drug interactions. What it does not provide is numerical toxicity data. Online resources tend to be overwhelming in quantity and underwhelming in organization and usability. An example is Martindale's (www.sci.lib.uci.edu.HSG/ Pharmacy/html), which has loads of wonderful information... somewhere. Other magasites that may also be worth a visit are: www
