警察在干预自杀事件中的作用

自杀是一个严重的社会问题。面对当前日益严峻的自杀问题,警察作为维护国家安全、维护社会治安秩序、保护人民生命财产安全的重要力量,在多数情况下是自杀现场的第一处置人员。因此,正确认识自身在处理自杀事件中的角色,掌握恰当的干预自杀的方法与技巧,对于警察来说是极其重要的。     

An analysis of self-reported suicide attempts and ideation in a national sample of incarcerated individuals convicted of sexual crimes

ABSTRACT

Suicide is the leading cause of preventable death in US jails and prisons, with rates three to nine times higher than those of the general population. Although suicide in correctional settings has been recognised as a serious problem, the research on suicide among incarcerated individuals remains limited. Individuals who have committed sexual offenses may be at an elevated risk for suicide. Specifically, they have been found to report high rates of hopelessness and depressive mood, and approximately 14% of individuals convicted of sexual offenses have reported a suicide attempt at some point in their lives. Most of these data are based upon official reports and may represent an underreporting of the true prevalence of the problem. The current study provides an analysis of the prevalence and factors associated with self-reported suicidal thoughts and behaviours in a large national sample of individuals convicted of a sexually based crime. Overall, 17.9% of the offenders reported an attempted suicide in their lifetime, 15.1% reported experiencing suicidal ideation but never made an attempt. Risk factors for suicide attempts and ideation for this population are reported. The findings are discussed in the context of suicide prevention and intervention efforts among those who have committed sex offenses.     

Suicide by blasting caps: a case study of rare cranial trauma

Suicide is a deliberate act of ending one's life. Suicide by use of any explosive device, when not involved in a terrorist act, is quite rare in occurrence when compared with other methods routinely utilized. In this paper, we present to the medicolegal community a case of an adult male who committed suicide with blasting caps and the subsequent extensive damage to the cranial hard tissue. Although the cause and manner of death were relatively straightforward, consultation with forensic anthropologists was requested for an anthropological trauma assessment of the highly fragmented skull. After the skull was cleaned and reconstructed, the analysis revealed similarities between blasting cap trauma to the head and high velocity gunshot trauma to the head. Therefore, in a case where some evidence may have been removed or destroyed, forensic analysis involving trauma of this magnitude could result in a misinterpretation of the true mechanism responsible for the osseous damage. In this case, cooperation among the law enforcement agency, coroner's investigators, the forensic pathologist, and forensic anthropologists provided a comprehensive death case analysis.     

接受审查犯罪嫌疑人自杀倾向的识别及化解

公安机关对犯罪嫌疑人的正面调查或审查会导致其心理的巨大波动,甚至产生轻生的念头,并在公安机关办公区域付诸行动,给公安机关带来巨大的社会压力。涉案人员非正常死亡专项斗争的开展,推动民警理性认识引发犯罪嫌疑人自杀的诱因、自杀倾向的识别以及自杀倾向的化解等问题,以指导公安机关用科学方法对涉案人员非正常死亡问题的解决。     

恐怖爆炸仍为世界和平的主要威胁

当前,在恐怖活动当中。恐怖爆炸袭击占主导地位,并呈现不断恶化的趋势,袭击方式主要是自杀式恐怖爆炸,袭击目标转向平民和民用设施,伤亡人数逐年递增。且多为平民和警察。恐怖活动不断向中东、南亚等少数地区集中。恐怖爆炸威胁着世界和平。     

Self‐harm Risk Among Adolescents and the Phenomenon of the “Blue Whale Challenge”: Case Series and Review of the Literature

The “Blue Whale Challenge” is a dangerous Internet phenomenon. As per media reports, it involves a series of life‐threatening tasks imposed by a “curator” to “players,” who must fulfill the whole list, and it ends with the suicide of the player. The authors report the data of five suspected cases of “Blue Whales” managed from January 2016 to December 2017 by the staff of a unit (the “Bambi Unit” of the Pediatric Hospital “Regina Margherita” of Turin, Italy) that is dedicated to the evaluation of suspected abused children. Then, they analyzed this data in the light of the literature regarding self‐harm. This comparison highlights the role of the Internet in the spreading of self‐harm behavior among vulnerable adolescents who are characterized by epidemiological, psychological, psychiatric, social, and cultural risk factors. In conclusion, the authors suggest a multidisciplinary and specialized approach in the evaluation of adolescents who committed self‐harm activities.     

Ingestion of pointed objects in a complex suicide

A 51-year-old woman with a psychiatric history of depression and drug abuse was found hanged in her bedroom. The ligature was a scarf attached to the door handle. The autopsy findings suggested that two methods of suicide had been used one after the other. In the first stage, numerous nails, pins and needles were swallowed; in the second stage, the suicide was completed by hanging.     

Self‐Strangulation Turning into Partial Hanging for a Suicide Victim

Hanging is the most common asphyxial method of suicide, whereas suicide by strangulation is unusual. Here, we are reporting a particular methodology of the asphyxial method of suicide in which a case of self‐strangulation culminated into partial hanging. A 30‐year‐old male wrapped one end of the cable wire around his neck. He then passed the other end over a curtain rod and tied that end around the right hand. He pulled the hand down, using the curtain rod as a fulcrum, to tighten the noose around the neck in an attempt to strangulate himself. However, he lost consciousness during the process and the body slipped down, pulling the right hand up which got stuck at the curtain rod. This led the body hanged in the kneeling position. This bizarre scenario raised suspicion of homicide but the crime scene, autopsy and victim characteristics were in favor of suicide.     

Hands Tied with Bag Full of Books in Suicidal Hanging

Hanging deaths associated with binding of limbs, masking of a face, and gagging are always suspicious. In suicidal hanging, the victim uses these added techniques to prevent him from backing out of his decision and to ensure death. However, binding of limbs and adding extra weight to the suspension in hanging are not reported. Herein, we report a case where the victim tied a bag containing books weighing 7 kg (15.4 lbs) to both his hands during hanging. The forensic specialist must be aware of the unusual presentation of suicidal hanging which may suggest foul play. The manner of death must be established after detailed analysis of circumstantial evidence, information obtained from the witnesses, complete autopsy, and toxicological examination.     

Fatal Insulin Overdoses: Case Report and Update on Testing Methodology

Suicidal insulin overdoses are an under‐recognized and uncommon cause of death, often relying on scene and nonspecific autopsy findings. Here, we present a case report of a fatal exogenous insulin overdose in a patient with type 1 diabetes. In our case, there were no contributory autopsy findings; however, serum analog aspart insulin levels were c. 10× the predicted therapeutic upper limit (4000, reference 6.6–55 uU/mL), which correlated with scene findings. This was specifically determined by a newly developed immunocapture liquid chromatography–tandem mass spectrometry assay, able to discriminate between various synthetic insulin analogs. Total insulin levels by immunoassay were highly elevated on the Siemens Advia Centaur, but not the Roche platforms (4741 vs. 5.2 uU/mL, respectively), showing variable sensitivity of detection within the same analog depending on assay. We discuss the prevalence and features to look for at autopsy in these types of cases. Additionally, analytical options for testing insulin levels, including new methodologies, guidance on collection of samples, as well as an outline of available historical reference range data are discussed.
