DOI: 10.1177/1088767908319597 Suicides and Suicide Attempts Following HomicideVictim–Suspect Relationship, Weapon Type, and Presence of AntidepressantsHarvard School of Public Health, Boston, cbarber{at}hsph.harvard.edu

Among 1,503 homicide incidents, less than 5% (n = 74) were followed by the perpetrator's suicide and 1% (n = 18) by a nonfatal suicide attempt. However, among men who killed their female intimate partner with a firearm, 59% also took their own life. Homicide–suicide perpetrators did not test positive for an antidepressant more often than other male suicide decedents (15% vs. 19%). Most (54%) perpetrators of nonfirearm homicides who attempted suicide lived; nearly all (93%) firearm perpetrators who attempted suicide died. Among men who killed their female intimate partner with a firearm, homicide–suicide was the norm. Better enforcement of existing laws designed to protect abuse victims by removing firearms from domestic abusers may also prevent abusers' suicides.
