Abstract

Homicide-suicide represents a single episode of violence which may decimate an entire family. This study aimed to further describe motives and context of these tragedies. Psychological autopsies were completed for 18 homicide-suicide cases in Dallas, Texas. This included postevent interviews with surviving family members and review of police and coroner records. Two-thirds of perpetrators had made either verbal or written threats prior to the homicide-suicide. A simplified typology describing victim-perpetrator relationship and motive type is suggested for future studies and clinical ease. Two-thirds of perpetrators fell into the category of Intimate-Possessive, most of whom were depressed men who were abusing substances and undergoing separation. Additional categories included Intimate-Ailing, Filial-Revenge, Familial-Psychotic, and Friend-Psychotic. Further, implications from this psychological autopsy study regarding risk assessment include use of collateral interviews regarding threats and past violence.
