Abstract
Most research on mass murderers to date has focused on perpetrators of male sex, while research on perpetrators of female sex has been relegated to case reports and series. We aimed to more fully examine the phenomenon of female-perpetrated mass murder. We analyzed 1715 worldwide incidents of personal-cause mass murder from 1900 to 2019, identifying 105 (6%) events perpetrated by females. We defined mass murder as any event involving at least three fatalities, not including the perpetrator, using any method. We identified cases of mass murder from English-language databases of mass murder or murder in print or online. There were no significant differences in age and race between female and male perpetrators. Relative to males, female perpetrators were significantly less likely to employ firearms in their mass murders, using them in less than half of cases, compared to over 70% for males. The prevalence of psychotic signs and symptoms among female mass murderers was more than double that among males (25.7% vs. 12.5%, p < 0.01), while the rate of nonpsychotic psychiatric or neurological conditions was also much greater among female perpetrators (29.5% vs. 17.1%, p < 0.01). Over half of female perpetrators took or attempted to take their own lives. More than three-quarters of mass murders by females involved at least one family member as a victim. This study underscores sex-specific differences in the perpetration of mass murder and the need for further research to understand how insights about such dynamics might lead to the development of more effective and informed intervention policies.
期刊介绍:
The Journal of Forensic Sciences (JFS) is the official publication of the American Academy of Forensic Sciences (AAFS). It is devoted to the publication of original investigations, observations, scholarly inquiries and reviews in various branches of the forensic sciences. These include anthropology, criminalistics, digital and multimedia sciences, engineering and applied sciences, pathology/biology, psychiatry and behavioral science, jurisprudence, odontology, questioned documents, and toxicology. Similar submissions dealing with forensic aspects of other sciences and the social sciences are also accepted, as are submissions dealing with scientifically sound emerging science disciplines. The content and/or views expressed in the JFS are not necessarily those of the AAFS, the JFS Editorial Board, the organizations with which authors are affiliated, or the publisher of JFS. All manuscript submissions are double-blind peer-reviewed.
