IntroductionFratricide comprises approximately 2% of all intra-familial homicides. Analyses of national data on fratricide show that adult males are considerably more likely to be offenders and victims or fratricide. A previous study suggested there were two main categories of fratricide: related to alcohol intoxication or associated with mental disorder.ObjectivesPresent and discuss the results of an original study comprising 28 cases of fratricide.AimsTo provide up-to-date scientific knowledge on fratricide.MethodThis is a retrospective study of 28 cases of fratricides, extracted from a sample of over 1000 consecutive cases of coroners’ files of victims of domestic homicide occurring between 1990–2015.ResultsTwo victims out of three were males, most of adult age. There were only 2 female offenders in the whole sample. A majority of victims were Caucasians while 21% were aboriginals. Most victims were stabbed to death. The murders usually occurred at the residence of the victim. In total, 39% of offenders suffered from a major mental illness; 21% were acutely intoxicated at the time. In victims, 29% were under the influence of alcohol and 18% of offenders were free from mental problems.ConclusionOur data indicates that fratricides are most often impulsive and lack preparation. The most common method was the opportunistic use of a knife, suggestive of impulsive killing, and this is consistent with the rest of the information including the high rate of alcohol use and intoxication at the time. The study confirmed two main categories of fratricide: impulsive killing in the context of alcohol and dispute and killing associated with psychosis.Disclosure of interestThe authors have not supplied their declaration of competing interest.
Objective. To describe a psychiatric profile and characteristics of physicians who killed themselves in Quebec between 1992 and 2009. Method. The cases of 36 physicians (7 females and 29 males) and 36 nonphysicians who committed suicide were matched for age and gender and examined in a nested case control design. All subjects were judged as definite suicide by the Quebec Coroner Head Office. Consensus regarding DSM-IV diagnoses was established by two forensic psychiatrists. Results. Rates of all Axis I diagnoses were 83% for physicians and 91% for nonphysicians at the time of suicide. Major depressive disorders were the most frequently observed pathology in both groups (61% and 56%, resp.). Conclusions. Physicians and nonphysicians who committed suicide in Quebec suffered from the same type of psychiatric disorder at the time of killing themselves. The findings advocate strongly for more efficient suicide prevention measures including early detection and treatment of mood disorders for the physicians.
Spousal homicide perpetrators are much more likely to be men than women. Accordingly, little research has focused on delineating characteristics of women who have committed spousal homicide. A retrospective clinical review of coroners' files containing all cases of spousal homicide occurring in Quebec over a 20-year period was carried out. A total of 276 spousal homicides occurred between 1991 and 2010, with 42 homicides by female spouses and 234 homicides by male spouses. Differences between homicides committed by female offenders and male offenders are discussed, and findings on spousal homicide committed by women are compared with those of previous studies. Findings regarding offenses perpetrated by females in the context of mental illness, domestic violence, and homicide-suicide are explored. The finding that only 28% of the female offenders in the Quebec sample had previously been subjected to violence by their victim is in contrast to the popular belief and reports that indicate that most female-perpetrated spousal homicide occurs in self-defense or in reaction to long-term abuse. In fact, women rarely gave a warning before killing their mates. Most did not suffer from a mental illness, although one-fifth were acutely intoxicated at the time of the killing. In the vast majority of cases of women who killed their mates, there were very few indicators that might have signaled the risk and helped predict the violent lethal behavior.
