Complex suicides--a review of the literature

The term "complex suicide" stands for suicides committed by using more than one method. A distinction can be made between planned and unplanned complex suicides (primary/secondary combinations). In planned complex suicides 2 or more methods are applied simultaneously in order to make sure that death will occur even if one method fails. In unplanned complex suicides the mode of performance is changed after the first method chosen failed or was working too slow or proved to be too painful. In planned complex suicides typically two of the generally common methods of suicide (e.g. ingestion of medicines, hanging, use of firearms, drowning, fall from a height) are combined. But also unusual combinations have been described such as the simultaneous firing of two guns, self-immolation in combination with other suicide methods or shooting oneself while driving a car. In unplanned complex suicides self-inflicted injuries by sharp force, especially cuts of the wrists, are often found as the primary act of suicide. In some cases the suicide switches from cuts to stabs (mostly to the heart region). Other methods often used after the first phase of suicide are hanging and jump from a height. In the literature the use of up to 5 suicidal methods applied one after the other have been described.     

Why Do People Hang Themselves on Trees? An Evaluation of Suicidal Hangings on Trees in Konya,Turkey, between 2001 and 2008

Hanging is the most common method of suicide in the world, and many public places offer a means or opportunity to carry out the activity. Of 4,452 death examinations and autopsies, there were 378 (8.5%) suicides and suicide method was hanging in 185 (48.9%) cases. In 20 of these (10.8%), the suspension point was the branch of a tree. The incident location was the garden of the victim's house in nine cases, the woodlands in seven cases. The suicides were attributed to psychiatric disorders in nine cases, economic problems in six cases, and family problems in five cases. It is concluded that hanging on a tree as a suicide method is often committed by males and the underlying motive may be different in suicidal hangings on trees occurring at daytime and night. For preventional purposes, the reporting of such suicides in public places by the media may be restricted by local authorities.     

Suicides in East Berlin from 1980 to 1989

In the analysed period from 1980 to 1989, 3.480 suicides (= 34.6%) were among the 10.064 corpses admitted to the Institute of Legal Medicine of the Humboldt University in Berlin. The share of men who committed suicide was higher than the share of women with the average ratio being 1.4:1. The preferred suicide method in men was hanging and in women drug intoxication. The decrease of the formerly common carbon monoxide poisoning is attributable to the switch from town gas to natural gas. Autopsies showed that only about one third of the individuals who had committed suicide had been under the influence of alcohol at the time of death. In most cases the suicides were committed in the suicides' own flat. It also turned out that there was a seasonal peak of suicides in spring.     

Planned Complex Occupation‐related Suicide by Captive‐bolt Gunshot and Hanging*

Abstract: Planned complex suicides are committed by using two or more previously planned methods simultaneously to make sure that death will occur even if one method fails. Herein, we presented a case of occupation‐related planned complex suicide, committed by captive‐bolt gunshot and hanging. A 29‐year‐old man, who worked as a butcher, was found dead in the stable, hanging by the neck with a captive‐bolt gun embedded in the forehead region of his head. The hanging was complete. Along the bolt canal were bone fragments, and at the end of the path was the punched‐out fragment of the skin and soft tissue. There were no fractures of the hyoid bone and laryngeal cartilages, and a superficial hemorrhage was present in the right sternocleidomastoid muscle. Our case underlines the utility of forensic autopsy and death scene investigation in reconstructing the mechanism of death, as well as the dynamics of the event.     

Electrocution--autopsy study with emphasis on "electrical petechiae"

Fatalities caused by electrocution (n = 37) were re-examined on the basis of the autopsy records, the police reports and the technical expertise. Accidents including two lightning deaths caused 2/3rd and suicides 1/4th of the fatalities and there were two homicides. Carelessness or ignorance were a major reason for accidental deaths while technical defects could be verified in five cases only. Low-voltage ac and male victims predominated. Electrical burns or current marks were detected in 81% including all high voltage electrocutions. The seven victims lacking burns were electrocuted in a wet environment including six cases of suicide in the bathtub with a hair drier. Petechial haemorrhages were present in 74% of the cases and the favourite sites were the skin of the eyelids, conjunctivae, visceral pleura, and the epicard. The presence of petechiae did not depend on the voltage or the current pathway relative to the heart. It is, therefore, suggested that the petechiae are not caused by asphyxia but by a combination of venous congestion due to cardiac arrest and a sudden rise in blood pressure induced by muscle contractions. Consequently, "electrical petechiae" represent a non-specific but typical finding in electrocution irrespective of the mechanism leading to death. Unlike electrical burns, petechiae also indicate the vital origin of the events. The relevance of this typical morphological sign in the examination of possible electrocution fatalities is therefore emphasised.     

Suicide by electrocution with low-voltage current

Three cases of suicide by electrocution with low-voltage current were observed in five years (1994-1998) by medical clinical forensic examiners of an Emergency Forensic Unit of the Paris suburb among 2,000 external death examinations. The cases involved one woman, aged 72 and two men, aged 38 and 41. In the last two cases, electric burns were retrieved under bared electric wires, placed on the arms or fingers in order to realize a hand-to-hand electric circuit involving the heart muscle. In the other case, the electric circuit between mouth and foot also involved the heart muscle. Household low-voltage current delivered (220 V in France) had a sufficient strength to induce local muscular paralysis and heart fibrillation. In the three cases, blood samples taken have retrieved very high levels of muscular enzymes (CPK, LDH) correlated to the mechanism of electric death. The rareness of suicide by electrocution and its forensic characteristics are detailed in order to help the clinical forensic examiners, prosecutors, and police officers concerned by such death examinations.     

Suicide by hanging. A review of 56 cases

Fifty-six consecutive cases of suicide by hanging are reviewed. The data provide some evidence for associations between suicide by hanging and youth, incarceration, black males, and clustering. Evidence was noted of low incidence in females, rarity of white female hangings at home, a preference to hang oneself away from home if there have been previous suicide attempts, and possible seasonal trends which may differ from suicide overall. Thus, aside from the method chosen, hanging victims as a group displayed some differences from suicides in general.     

Unusual hanging deaths

Four unrelated hanging deaths involving young white males, all in enlisted status in the United States military, are presented. Taken in a military context, one scene served as a suicide note equivalent with the unmistakable message of extreme defiance toward military regulations. In two cases, the elaborate attire of the decedents could have lead to the misclassification of the manner of death if investigative information had not been considered. Extensive background investigation and review of medical records in the fourth case disclosed that the victim had an eight- to ten-year history of compressing his neck to cause unconsciousness. He left an extensive suicide note in which he concluded that "hanging would be good." Each case has certain unique features, as a group, the cases all demonstrate a continuum from obvious suicide to cases where the manner of death is, at first, equivocal.     

Mortality in maximum security psychiatric hospital patients

Numerous studies have mentioned to the high percentage of violent deaths in prison psychiatric hospitals, with suicide being the principal cause. The aim of this study was to analyze the circumstances related with the deaths recorded in a high security institution. Postmortem reports on all the deaths at the Alicante Psychiatric Prison between 1984 and 1997 were studied (36 cases of unnatural death and 28 of natural death). Of the violent deaths recorded 34 (94.4%) were suicides. Demographic, clinical and interpersonal variables factors were registered. In the cases of suicides, the method used, the place of death, season, month and time of suicide were analyzed. In our study, 64.7% of suicides were schizophrenic and 32.4% had inflicted self-harm previously. We found a statistically significant association between the cause of death (natural, suicide or homicide) and age, 47.1% of suicides being between the ages of 18 and 30 and 29.4% between the ages of 30 and 45. Natural causes predominated in older subjects. The prison population studied showed grave negative traits, mental illness and criminal behavior having forced them to the very edge of society. Our results were compared with the death and suicide rates of the general Spanish population.     

Suicide in children and adolescents at a province in Turkey

Despite the well-documented increases in the rate of completed suicide among children, accurate knowledge of the characteristics of these suicides is limited. We examined all suicides by children and adolescents in Diyarbakir during 1999 and 2001. All of the cases were analyzed regarding the age, sex, method and location of suicide, time of year, and predictive factors. There were 56 children aged 11 through 19 years. Adolescents between 15 and 19 years of age constituted the overwhelming number (87%) of all the childhood suicides. Female children and adolescents predominated among the suicide victims (71%). The most frequent means of suicide were firearms (43%), hanging (28%), and jumping (16%), respectively. The majority of suicides occurred at the decedent's home (88%). Reasons identified were mainly psychiatric disorders, followed by troubles within the family. A prior suicide attempt or a note that was left by the decedent and elucidated the reason for the suicide was rare. There was no seasonal difference in rates of suicides.     

Characteristics of young suicides by violent methods in rural China

Suicide is one of the most common public health problems in the world. Information on 392 completed suicides aged 15-34 years were consecutively collected from 16 counties in three provinces of China. Information on each suicide was obtained from two informants. The results showed ingesting pesticides or other poisons (73.5%) and hanging (10.5%) were the two most common methods of suicide. Suicides happened more in autumn (30.10%) or summer (27.29%), nighttime (68.3%), and at home (73.6%). However, suicides with violent methods were more common in winter and spring and outside of home. Season (autumn or summer), place (at home), and pesticide stored in home were negatively while depression was positively associated with violent methods of suicide. Characteristics of the suicides by violent methods are different from those by nonviolent methods. Investigations into the methods of rural young suicides are necessary for suicide prevention in China.     

Planned complex suicide: report of three cases

Three cases of planned complex suicide in a 3-year period are reported. A 40-year-old man was found dead, in his garage, hanging by his neck, with a gunshot in the head from a pen gun. A 50-year-old man was found dead in the sea with a gunshot to his head. A third man was found in a field hanging by a tree and burned. The investigation of the scenes and the methods used pointed toward a suicidal etiology. The main difference between planned complex suicide and those cases defined in medicolegal literature as combined suicides lies in the complex mechanism used by the victim as a protection against the failure of one of the mechanisms.     

Suicide in children and adolescents: a 10-year retrospective review

Suicide is second only to accidents as the most common cause of death for children and adolescents age 10 to 19 in Canada. All of the pediatric cases that were referred to the Hamilton Regional Forensic Pathology Unit from 1993 to 2002 were reviewed. For the purpose of this study, pediatric deaths were defined as deaths in the age group of 1 day up to and including 19 years of age. Specific criteria for suicide were applied to each case, independent of the manner of death issued by the coroner. The criteria were 3-fold. First, homicide had to be ruled out by the police investigation and autopsy findings. Second, the method had to be consistent with self-infliction. Finally, there had to be some evidence of suicidal intent. Questionable cases were discussed among the authors, and if reasonable intent could not be established, then the case was excluded. The autopsy and police reports were examined in detail regarding age, sex, location and method of suicide, presence of suicide notes, and any contributing psychologic factors or stressors. Of the 501 pediatric autopsies performed during the 10-year period, 31 (6%) met the criteria of suicide. The majority of cases (87%) were in older adolescents (age 15 to 19), and the male to female ratio was 2.4:1. Psychologic factors were identified in some of the cases, including depressed mood (77%), suicidal ideation (45%), previous suicide attempts (23%), and drug or alcohol problems (19%). Most of the suicides (61%) occurred in the victim's home, and 12 (39%) cases left a suicide note. In 9 cases (29%), alcohol or street drugs were detected postmortem, though in 8 cases toxicology was not performed. Hanging (48%) was the most common method of suicide, followed by firearms (13%), poisoning (10%), drowning (10%), and blunt force vehicular trauma (10%). Almost 60% of the male suicides were by hanging. No specific trend was identified in the 9 female suicides. These results were compared with similar studies within Canada and other countries. Overall, the method of suicide is dictated by what is convenient and readily available, though the acceptance of various suicide methods can change over time. Suicide prevention efforts should be tailored to address local trends.     

Suicide by Medication Overdose in Prison: A Study of Three Cases

Suicide is one of the principal causes of mortality in a prison environment. Although suicide by medication overdose is less frequent than suicide by hanging, self‐strangulation, or vein cutting, it raises questions as to how the medications are obtained, particularly in view of the specific organization of the medication circuit in prisons. We present three cases of suicide by medication overdose involving different therapeutic classes with different distribution circuits and review the regulatory requirements and the measures that could be taken to prevent such suicides.     

Suicide: a ten-year retrospective review of Kentucky medical examiner cases

Suicide, a manner of death, ranked as the eleventh leading cause of death in the United States and accounted for approximately 30,000 deaths in 2001. A host of biological and psychosocial components interplay in a suicide investigation. Precipitating factors may include domestic quarrels, loss of employment, financial difficulties, substance abuse, chronic disease, or mental illness. The authors conducted a ten-year (1993--2002) retrospective review of suicide from all Medical Examiners' Offices in Kentucky. There were 2,864 suicides ranging between 11 and 96 years (average age 42.0 years). The majority of victims were males (81.7%) and Caucasian (94.8%). African-American females comprised the smallest group, consisting of only 0.59%. The preferred mode of death was by firearm (67.5%), followed by hanging (13.7%), overdose (9.9%), and carbon monoxide poisoning (4.4%). This comprehensive study discusses the trends of suicide in the United States during the twentieth century and underscores the importance of a multidisciplinary approach to the investigation and prevention of suicide.     

An unusual suicide case by combination of choking and hanging

ABSTRACT: A 40-year-old man was found dead in his prison cell, hanging on a twisted bandage tightened around his neck. His permanent metal tracheostomy tube was completely corked with a piece of paper wrapped with transparent cellophane from a cigarette case. After police investigation and complete autopsy, suicide was determined as the manner of death. Although suicides by 1 form of asphyxia are relatively common, combination of several different forms of asphyxia is far less frequent. We present this unusual and very rare case of suicide by combination of 2 forms of asphyxia, that is, choking and hanging, along with autopsy findings and discussion.     

Youth suicide in New Mexico: a 26-year retrospective review

Although suicidal behavior in children and adolescents is a major public health problem, large-scale research on suicide in this population is uncommon. In this study, we reviewed autopsy and field reports for all pediatric suicide cases referred to the New Mexico Office of the Medical Investigator from 1979 to 2005. The age-adjusted suicide rate was 4.8 per 100,000. Psychologic stressors and parasuicidal behavior were identified in some cases. Seventy-six percent of suicides occurred in the victim's home or yard, and 25% left a suicide note. In 26% of cases, alcohol or other drugs were detected in postmortem. Gunshot wound was the most common method overall (58%), followed by hanging (30%). Although the age-adjusted suicide rate is higher in New Mexico than nationally, the trends in the population are similar. With a solid understanding of the circumstances, it may be possible to predict, and hopefully prevent, future cases of child and adolescent death.     

Forensic Pathological Considerations of a Unique Case of “Complicated Suicide”*,†

In the forensic literature, peculiar and uncommon cases of suicides defined as “complicated” are reported. In these circumstances, the suicide method chosen by the victim fails, and death occurs due to a subsequent unforeseen accidental event defined as secondary trauma. Through retrospective examination of 25,512 autopsies in 27 years (1993–2019) at the Bureau of Legal Medicine of Milan, a unique case of complicated suicide was identified from a total of 4497 suicides. It concerns an elderly man who, after killing his wife by inflicting incised wounds to her neck, tried to hang himself by tying a rope to a heater and jumping from the window located over the heater itself. However, the rope suddenly snapped and the man fells to the ground causing fatal traumatic injuries. Death occurred because of an accidental event caused by the failure of the hanging mechanism. Therefore, a peculiar yet characteristic case of complicated suicide is described.     

自杀方式与性别和年龄关系548例分析

Suicidal electrocution in Sydney: a 10-year case review

A retrospective study was undertaken of all cases of death due to suicidal electrocution in Sydney, Australia between 1996 and 2005. A total of 25 cases were identified with 20 cases (80%) as a result of direct attachment to an electrical outlet and five cases (20%) as a result of immersion in a body of water with an electrical appliance. Twenty of the 25 individuals were men (mean age = 57 years, range 22-90) and five were women (mean age 67, range 53-88). At least 35% of decedents were either currently working or had worked as electricians. Electrical timers had been used in eight (32%) cases, the fuse blown in one case, but the remaining 16 (64%) bodies were "live" on arrival of witnesses or electricity personnel. This study demonstrates the phenomenon of electrical suicide as a regular occurrence in Sydney. We highlight the need for investigators and emergency workers to remain vigilant upon discovery of electrical suicides, due to the fact that most bodies remain electrically active after death.
