Schizophrenia and suicide: a 10-year review of Kentucky medical examiner cases

The risk of suicide is significantly increased in schizophrenics; it is estimated that 10-13% of individuals suffering from schizophrenia commit suicide. Schizophrenia is marked by psychotic exacerbations and remissions, with persistent deterioration in baseline functioning with each relapse. We present a 10-year (1993-2002) retrospective review of Medical Examiners' cases of suicide of schizophrenic victims. Twenty-nine cases were between the ages of 20 and 75 (mean age of 41.6 years). The majority of victims were male (62.1%) and Caucasian (86.2%). The leading method of suicide for both males and females was firearm injury (48.3%) mostly of the head, followed by overdose (20.7%), and hanging (13.8%). A comprehensive investigation of the biopsychosocial factors is warranted in cases of schizophrenics who commit suicide. This study offers an insightful analysis pertaining to the determination of intent in formulating the manner of death in this unique population.     

Adolescent and young adult suicide: a 10-year retrospective review of Kentucky Medical Examiner cases

The compilation of all suicidal causes of death attained the third highest ranking of mortality between the ages of 15 and 24 following unintentional deaths and homicide in the United States, accounting for approximately 4000 deaths in 2002. A variety of biopsychosocial factors may contribute to adolescent suicidal behavior, including psychiatric disorders, risk-taking behaviors, and lack of a cohesive family unit. The authors conducted a 10-year (1993-2002) retrospective review of 108 Medical Examiner cases of suicide ages 11-17 and 358 cases ages 18-24 in Kentucky, which represents two thirds of the Coroner cases in the state. The majority of victims were male and Caucasian. The major causes of death were the same for the two age groups, specifically, firearm injury (72.2% and 70.7%), hanging (22.2% and 18.7%), and drug intoxication (2.8% and 5.3%). An integrated Coroner-Medical Examiner system profits in the public health arena by providing collaborative research data for policy decisions. The prevalence of youth suicide by firearm should prompt further discussion regarding ways to better identify high-risk adolescents and young adults and restrict pediatric access to unsecured household firearms.     

Complex suicide: an unusual case with six methods applied

Complex suicides (CSs) are committed by using more than one method. They account for 1.5-5% of all suicides. We present a case of CSs of a 44-year-old man, found dead in the vicinity of his car, in a deserted frozen field. Police investigation excluded homicide, and no medical data confirmed mental illnesses. Autopsy revealed wrist cuts, neck cuts, acid burns in the GI tract, multiple stab wounds to the head by a screwdriver, and several uncertain signs of hypothermia. Toxicology analysis (gas chromatography-mass spectrometry) confirmed ingestion of insecticide. We concluded that stab wounds to the head were the cause of death, while external hemorrhage and hypothermia were contributing factors. This is the first case of CSs reviewed in the literature where six suicide methods were applied. This particular case is interesting because the victim used a screwdriver as a tool for inflicting stab wounds to the head, which is a rare suicidal method.     

Death certification of "suicide by cop"

Death certification of "suicide by cop" is controversial among some medical examiners and coroners. We present five such deaths that were certified as suicides and discuss the medico-legal issues involved with these certifications. To certify such a death as a suicide, certain criteria should be met. Suicide by cop is a circumstance that involves competing intentional acts that may result in dichotomous determinations of the manner of death. Despite the absence of direct self-infliction, there is overwhelming evidence that these five individuals intended to end their own lives. Their use of an unusual method to accomplish this goal may inappropriately result in a reflexive certification of homicide. All of the decedents possessed weapons or a facsimile of a weapon. We present five instances of suicide by cop and contend that these types of deaths are best certified as suicides.     

An unusual case of a triple suicide pact at the time of the COVID-19 pandemic

In December 2020, the World Health Organization (WHO) declared SARS-CoV2 a global pandemic. Home confinement, low social contacts, and fear of virus transmission played a major role as risk factors for suicides during the following period. Suicide pacts, in particular, showed a different pattern. A rare case of a triple suicide pact among members of the same family nucleus is presented. The victims were an elderly, severely ill woman and her adult children (a son and daughter), linked by a morbid relationship. The last time the family was seen alive was 40 days before the discovery. All corpses presented decompositional changes. After a full autopsy, the cause of death was determined to be a lethal intake of morphine for the mother and acute blood loss due to self-stabbing at the neck for the siblings. The younger woman was under the effects of a large amount of heparin. Toxicological analysis was positive for opioids and alcohol in both siblings. Suicide pacts have rarely been described during the COVID-19 pandemic. In the few cases reported, the victims were more often relatives than people in a romantic relationship. The involvement of three people is unusual, as is the use of different suicide methods among the victims. In the presented case, the elderly mother's imminent death from terminal cancer, her concern over dying in a nondomestic environment, and the siblings' fear of being alone likely led to the conception of the suicide pact. Social isolation and economic difficulties also played a contributing role.

X线骨龄评估方法研究进展与展望

骨龄评估的传统方法主要包括计数法、图谱法及计分法等,近年来又有一些学者不断提出其他新的方法。利用骨骼X线片影像学特征推断骨龄是当前法医学工作者进行骨龄评估的主要手段。但是,将此骨龄推断结论作为"证据"直接提供给司法审判机关,因其存在着一定的误差尚值得商榷。因此,为了提高骨龄鉴定结论的精确度,还需进行更多方法学的研究。经参阅国内、外大量相关文献,现就X线片骨龄评估方法的研究与进展进行综述。

105例生前精神异常的水中尸体回顾性分析

目的：分析生前精神异常的水中尸体的特点,为此类案件鉴定和分析提供参考。方法调查2010年1月至2014年6月上海市公安局水上公安局检验的所有生前精神异常的水中尸体档案105例,对死者一般情况、尸检情况、案情调查情况和疾病史进行统计分析。结果自杀104例,死者受教育程度较低,天气较暖时案件较多,尸体多在2d内被发现。多数死者没有自杀史,没有遗书,但在临死前出现行为、心理的异常变化。抑郁症、抑郁状态和精神分裂症是主要的精神障碍类型,仅有9名死者曾坚持进行正规治疗。结论精神异常是投水自杀的高危因素,监护人员应该警惕患者的异常行为,特别是气温转暖时。
