Study of homicide characteristics in psychiatric homicide committers examined at Iranian Legal Medicine Organization during 1995-1997

Background: A review of international literature examining the link between psychiatric disorders and violent criminal behavior suggests that, although a small number of patients engage in violent crimes, the vast majority is unlikely to commit homicide. Contrary to public perceptions about psychiatric patients, the previous studies have found no evidence to support the notion that mentally disordered people are more likely to kill strangers in public places for no apparent reason. In contrast, mentally ill offenders who commit a homicidal act are more likely to victimize a family member in some private place. Methods: This study is based on available information in medical records of the persons who were examined in psychiatry department of Legal Medicine Organization of Tehran in a three- year duration period (100 people) and their psychiatric disorder was approved in the psychiatry commission sessions according to their psychiatric examination and past medical history. Results: The most common disorder was non-mood psychosis and only in 39% of cases, a documented reason for irresponsibility was found (Psychosis 33%, mental retardation 5% and seizure attack 1%). The final diagnosis in 32% of cases was none mood psychosis, 33% neurosis, 13% personality disorder, 13% mood disorder, 5% mental retardation and 4% epilepsy. Conclusion: In this study too, most of the offenders had killed a family member (46%)mostly at home (60%) and the fact that only military personnel had used guns to kill victims, notifies the importance of psychiatric evaluation before and after military employment.
