Hanging: suicide or homicide?

Death by Hanging: Suicide or Homicide. Six cases of homicidal hanging and murder presented as suicidal hanging are recorded. Suspension followed strangulation by ligature or throttling and head injuries in 4 cases. Distinction between homicide and suicide was easy in 5 cases: two of the perpetrators gave themselves up to the police, one committed suicide immediately after he had hanged his 15 year old daughter; in two cases tracks of blood, heavy injuries of the victims, and traces of robbery were obvious. Unless the victim is an infant or an adult person incapacitated by drink, disease, or drugs, or unless there are several assailants murder is difficult to accomplish. Distinction between murder and suicide may be impossible by an examination of the body alone. Detailed investigation of the scene, reconstruction of the position of the suspended body, examination of the rope, the knots, the direction of the fibres on the rope may serve to discover homicidal hanging. - Compared to suicidal hanging homicide has a frequency of about 1% in our autopsy material. However, we cannot estimate the number of obscure cases.     

A case of stalking in the workplace and subsequent sexual homicide

A case of stalking in the workplace and subsequent sexual homicide by a 33-year-old male is reported. Following several months of stalking a 38-year-old female, the male subject went to the woman's office after business hours and restrained, raped, and murdered her. The cause of death was multiple stab wounds. The facts of the case reveal that the subject fits a predatory-type stalker, which represents a small subgroup within stalkers that has received little attention. Unlike other types of stalkers, the predatory stalker gives little warning to their victim (or multiple victims), as their stalking behaviors tend not to be very invasive or harassing. In general, most stalkers are not physically violent; however, predatory-type stalkers, given their tendency for sexual violence, are dangerous and the importance of identifying them is emphasized. Factors associated with perpetrators of sexual homicide are discussed.     

Global functioning and suicide among Chinese rural population aged 15-34 years: a psychological autopsy case-control study

As the relationship between global functioning and young suicide remains unclear in rural China, this study was aimed to explore the relationship between them. Data of 391 rural suicides and 416 controls, all aged 15-34 years in three provinces in China were used for this study. The Global Assessment of Functioning (GAF) scale was adopted to assess global functioning of suicides and controls. The results showed that GAF score was stronger than mental illness in predicting suicide in China. Different correlates of GAF score were found between suicides and controls. Unsurprisingly, GAF score was significantly correlated with mental illness in both suicides and controls. Different characteristics were also found among three types of suicide which were classified using GAF score. Assessing global functioning is useful and GAF scale should be regularly used in suicide prevention practice.     

Dextromethorphan abuse leading to assault, suicide, or homicide

Abstract: Dextromethorphan is a commonly encountered antitussive medication which has found additional therapeutic use in the treatment of pseudobulbar disorder and as an adjunct to opiate use in pain management. Dextromethorphan at high doses has phencyclidine‐like effects on the NMDA receptor system; recreational use of high doses has been found to cause mania and hallucinations. The toxicology and pharmacology of the drug in abuse are reviewed, and the historical literature of adverse psychiatric outcomes is assessed. Five new cases of dextromethorphan intoxication that resulted in assault, suicide, and homicide are reported, together with the corresponding toxicology results. Blood concentrations ranged from 300 to 19,000 μg/L. These results are compared with typical concentrations reported in therapeutic use and impaired driving cases. Based on these findings, dextromethorphan should be considered as a potential causative agent in subjects presenting with mania, psychosis, or hallucinations, and abusers are at risk for violent and self‐destructive acts.     

Nail-gun injuries. Accident, homicide, or suicide?

It may be difficult to distinguish industrial accidents from suicide attempts or even assaults or homicide. Nail guns are relatively new industrial tools that can produce severe or fatal injuries. The configuration of the nail on patients' radiographs after such injuries can be helpful in determining the cause of injury. Steel nails that are bent are due to a ricochet and thus indicate accidental injury. Straight-nail injuries to the co-workers of nail-gun users are most likely due to over-penetration of the substance being nailed or accidental mid-air firing; however, intentional injury cannot be ruled out. Extremity injuries caused by straight steel nails in nail gun users are the result of carelessness or poor technique, but suicide should be considered when straight nails cause wounds to the chest, head, or abdomen.     

Aggression homicide and rejection homicide: a communicative classification of homicide

Based on a 10-year sample of homicides (n = 50), the hypothesis was tested that it is possible to differentiate between aggression and rejection homicide. The aggression homicide results from the offender/victim relationship, which is no longer accepted for some reason. In contrast, in the rejection homicide the offender radically strives for a goal which can only be reached if the victim is eliminated. Based on forensic-psychiatric expert opinions (n = 50), the case analyses yielded 31 aggression homicides and 18 rejection homicides, one case could not be classified. Aggression homicides differed significantly from the rejection homicides with regard to their main motives. Hate in quarrel (n = 8), violent occupation of the victim (n = 7), delusions (n = 5), revenge (n = 3), self-defence (n = 2), and jealousy (n = 1) characterized the aggression homicides, whereas rejection homicides were dominated by economic motives (n = 14). Two offenders intended to get rid of the victim and one offender wanted to rescue a third person. From a forensic-psychiatric point of view, the pertinent statistical data (social data, diagnosis, criminal responsibility) are reported and the significance of the differentiation between aggression homicide and rejection homicide for medico-legal or criminological case profiling and for the prognosis of the risk potential is discussed.     

Plastic bag as the method in suicide and homicide

The report describes a suicide and a homicide by suffocation in a plastic bag. Both cases were copy-cat acts. The suicide copied the method--taking medicines and pulling a plastic bag over his head from a personal model. In the homicide the perpetrator followed the example of a film sequence from the US feature film "Charade".     

Female juvenile murderers: Biological and psychological dynamics leading to homicide

The increasing involvement of girls under 18 in violent crime has been a matter of growing concern in the United States in recent years. This article reviews the arrests of female juveniles for violent crime and then focuses specifically on their involvement in homicide. Arrests of girls for murder, unlike arrests for assault, have not risen over the last 30 years, suggesting that the dynamics that propel female juveniles to engage in lethal violence differ from those contributing to assaultive behavior by this same group. A review of the literature indicates that theories as to why female adolescents kill do not take into account recent scientific findings on brain development and the biological effects of early trauma in explaining serious violent behavior by girls. Three cases, evaluated by the authors, involving female adolescents charged with murder or attempted murder, are presented. The authors focus on the biological and psychological dynamics that help explain their violent behavior. They discuss the effects of insecure attachment and child maltreatment, and trace a critical pathway between these early experiences and future risk of violent behavior. The dynamics of child maltreatment in fostering rage and violence are discussed thereafter in terms of offender accountability. The article concludes with a discussion of treatment and recommendations for future research.     

Sharp force fatalities: suicide,homicide or accident? A series of 21 cases

Cases at study comprise 21 sharp force fatalities (9 suicides – 7 m and 2 f; 8 homicides – 5 m and 3 f; 2 accidental deaths – 1 m and 1 f; 2 uncertain cases – 2 m), examined from 1993 to 2002. Suicide age range was 17–75 years, mean 42.4; in seven cases the age was upper 40. Scene of death was at home in six cases, at open place in two, during hospitalisation in one. Incised wounds were pre-eminent in suicides. Homicides showed multiple stab wounds. The two accidents were caused by “glassing”. Uncertain cases were a small stab wound to the chest and an eviration.     

Determination of questionable suicide as a homicide by studies of criminal stains

In a woman found dead with cuts on both arms in a domestic sauna plastered with blood were assumed next to a bleed to death. The question self-infliction or by a third party of arm injuries could not be decided. By investigation of blood traces only could be clarified the cause of death. The husband had strangled his wife and inflicted several cuts on both arms with a razor blade to simulate suicide. Afterwards, he also inflicted several cuts on himself with a razor blade with the intention of suicide. He survived these injuries.     

Criteria for homicide and suicide on victims of extended suicide due to sharp force injury

This report is about the findings in association with the extended suicides of nine victims killed by sharp force. All victims were killed by sharp force. The perpetrators were predominantly the parents, the victims their children. Regarding the criteria for differentiating self-inflicted injuries from injuries inflicted by another person, the victims' injuries presented patterns usually found solely in suicides. Thus eight of nine cases presented tentative and hesitation injuries, in three of five cases areas of injury covered by clothing had been exposed beforehand. Despite extremely narrow intercostal spaces in children, injuries to the bones in thoracic stabbing were avoided more often than not (four of seven cases). Only the criterion "defence injury" occurred nearly as often as in homicide victims (three of nine cases). The psychopathology of extended suicide can explain this pattern. The perpetrator's motive is characterised by his pseudoaltruistic belief to save the loved ones from a world that is in his opinion unacceptable. A fusion or integration of the victim into the perpetrator's own self is based on an identity problem. Physical interrelation of forces between perpetrator and victim restricts the victim in his defence and presents an important prerequisite for acquiring the patterns of described injuries.     

Child and adolescent suicide in a large, urban area: psychological, demographic, and situational factors.

We examined all completed suicides by children and adolescents in Los Angeles County who died during 1996 and 1997. There were 46 subjects, aged 11 through 16. The majority of the decedents were males and over age 14. The predominant racial group was Hispanic. There was an almost even split between firearms and hanging as the means of death. Females had a statistically significantly higher rate of prior suicide attempts than males. Over one-third left a suicide note, almost one-half were noted to be depressed, and 22% tested positive for alcohol or illicit drugs. Less than one-quarter were in mental health treatment. Eighty-seven percent had difficulty transitioning to or during adolescence; e.g., problems at home, legal and school difficulties, and relationship losses. These findings are discussed in terms of Eriksonian developmental theory. We offer recommendations for intervention and prevention of suicide.     

Participant gender,stalking myth acceptance,and gender role stereotyping in perceptions of intimate partner stalking: a structural equation modeling approach

The present research used a mock juror experiment (N = 360) to assess two primary goals: (1) to examine the direct and indirect effects of participant gender, stalking myth acceptance, and gender role stereotyping on guilt ratings in a stalking trial; and (2) to examine the role of perceived victim fear and distress, and defendant intended danger on perceptions of a stalking trial. Using structural equation modeling, we found an indirect effect of participant gender, and both direct and indirect effects of stalking myth acceptance and gender role stereotyping on guilt ratings. Men and participants who endorsed more traditional gender role stereotypes were associated with adherence to stalking myth acceptance beliefs. Endorsement of particular stalking myth acceptance beliefs offers a partial explanation for why women and men differed on perceptions of the defendant's intent to cause danger and the victim's perceived fear and distress. Results provide insight into the efficacy of current anti-stalking legislation that relies on a juror's capacity to evaluate an ‘objective’ interpretation (i.e., ‘reasonable person’) standard of fear for intimate partner stalking.     

Stalking,homicide, and catathymic process: a case study

Despite the proliferation of research on various aspects of stalking, there has been relatively little study of stalkers who commit homicide. In this article, a man who stalked and killed a casual acquaintance is reported. He developed an idea to kill her that, at first, seemed ego-alien and unreal but eventually became fixed and was accompanied by a mounting inner pressure to act. The concept of catathymic process--a change in thinking whereby the offender comes to believe that he can resolve his inner conflict by committing an act of extreme violence against someone to whom he feels emotionally bonded--is of particular help in understanding this case, as well as similar cases of stalking that culminate in homicide.     

Fatal tolperisone poisoning: autopsy and toxicology findings in three suicide cases

Tolperisone (Mydocalm) is a centrally acting muscle relaxant with few sedative side effects that is used for the treatment of chronic pain conditions. We describe three cases of suicidal tolperisone poisoning in three healthy young subjects in the years 2006, 2008 and 2009. In all cases, macroscopic and microscopic autopsy findings did not reveal the cause of death. Systematic toxicological analysis (STA) including immunological tests, screening for volatile substances and blood, urine and gastric content screening by GC-MS and HPLC-DAD demonstrated the presence of tolperisone in all cases. In addition to tolperisone, only the analgesics paracetamol (acetaminophen), ibuprofen and naproxen could be detected. The blood ethanol concentrations were all lower than 0.10 g/kg. Tolperisone was extracted by liquid-liquid extraction using n-chlorobutane as the extraction solvent. The quantification was performed by GC-NPD analysis of blood, urine and gastric content. Tolperisone concentrations of 7.0 mg/l, 14 mg/l and 19 mg/l were found in the blood of the deceased. In the absence of other autopsy findings, the deaths in these three cases were finally explained as a result of lethal tolperisone ingestion. To the best of our knowledge, these three cases are the first reported cases of suicidal tolperisone poisonings.     

Intimate partner violence perpetration by court-ordered men: distinctions among subtypes of physical violence, sexual violence, psychological abuse, and stalking

This study continues previous work documenting the structure of violence perpetrated by males against their female intimate partners. It assesses the construct validity of a measurement model depicting associations among eight subtypes of perpetration: moderate physical violence, severe physical violence, forced or coerced sexual violence, sexual violence where consent was not possible, emotional/verbal psychological abuse, dominance/isolation psychological abuse, interactional contacts/surveillance related stalking, and stalking involving mediated contacts. Data were obtained from a sample of 340 men arrested for physical assault of a female spouse or partner, and court ordered into batterer intervention programs. Men were surveyed before starting the intervention. Confirmatory factor analyses (CFA) supported the validity of model as evidenced by good model to data fit and satisfaction of requirements for fit statistics. In addition, the eight factor solution was characterized by a slightly better model to data fit than a four factor higher order solution described in the author's previous work. Latent variable correlations across the broader categories of intimate partner violence (IPV) revealed that the violence subtypes were mostly moderately positively correlated and ranged from .381 (emotional/verbal psychological abuse with interactional contacts/surveillance related stalking) to .795 (dominance/isolation psychological with abuse with forced sex). Future studies should determine whether there are distinct risk factors and health outcomes associated with each of the eight IPV perpetration subtypes and identify possible patterns of co-occurrence.
