Military Versus Civilian Murder-Suicide

Area of Science:

• Forensic Psychology
• Military Mental Health
• Criminology

Background:

• Violent behavior, including suicide and domestic violence, differs between military members and civilians.
• No prior studies have specifically examined military murder-suicide perpetrators.

Purpose of the Study:

• To identify meaningful differences between military and civilian murder-suicide perpetrators.
• To compare demographic, psychological, and contextual factors of these groups.

Main Methods:

• Utilized data from the CDC's National Violent Death Reporting System (NVDRS).
• Compared military (n=259) and civilian (n=259) murder-suicide perpetrators using chi-square analyses.
• Employed logistic regression to identify predictors of perpetrator group membership.

Main Results:

• Military perpetrators were older, had more physical health problems, were more likely to be married/formerly married, and less likely to abuse substances.
• Motives for military murder-suicide differed significantly from civilian perpetrators.
• Age, physical health problems, and declining health motives predicted military perpetrator status, reflecting a >15-year age difference.

Conclusions:

• Military and civilian murder-suicide perpetrators exhibit distinct characteristics.
• Suicide risk assessments should be tailored to include murder-suicide specific questions and attitudes.
• Assessing suicide and violence risk in older adult military populations is crucial.
