Abstract
Murder-suicides are defined as the murder of at least one person and the suicide of the offender following the murder. The intention to commit suicide must be primary. In most cases, a male offender kills a female victim after a separation. The current analysis was the first analysis of the typology of murder-suicides in Berlin. We analyzed the autopsy files of the Institute for Forensic Medicine of the Charité University Medicine Berlin and of the City Institute for Forensic Medicine Berlin. We performed descriptive and statistical analyses of cases between 2005 and 2013. We identified 17 murder-suicides. All 17 offenders were male, and 20 of the victims (90%) were female. The offenders used firearms in the majority of the cases. In seven cases, the victims and offenders were at least 80 years old. The average age of the offenders was 63 years. Disease was the motive in 6 cases involving older offenders. Our study might support the development of prevention strategies. In this regard, it is important to build a database for murder-suicides in Germany and other countries, to formulate a uniform definition of murder-suicide, to carry out nationwide interdisciplinary studies on this topic and to improve the existing health care structures, especially for older adults and people with depression.
Highlights
A murder-suicide is defined as the murder of at least one person and the suicide of the offender following the murder
Dual suicides in which both individuals had suicidal intentions but the fatal action was taken by only one person were considered murder-suicides
We found 17 cases fulfilling the criteria for murder-suicides
Summary
A murder-suicide is defined as the murder of at least one person and the suicide of the offender following the murder. The intention to commit suicide must be primary. The time span between the murder and the suicide as part of the definition of a murder-suicide is controversial. Marzuk et al [1] defined the maximum time span as one week. The inclusion of a time span in the definition of a murder-suicide might help differentiate between murder-suicide and suicide out of remorse [2]. Most analyses of murder-suicides refer to newspaper articles or forensic files because in most countries, Female offenders of a murder-suicide usually kill their children (48.6%), whereas male offenders usually kill their intimate partner [6]. Domestic violence occurred in 25% of cases before the murder-suicide [3].
