This article describes homicide-suicide among those aged 65 years and older in the United States using archival data from 1968 to 1975. Comparisons were made between 184 homicide-suicides and 400 randomly selected victims of all other types of homicide. The findings indicate that homicide-suicides occurred predominantly in the family unit, especially involving female spouses, and among White victims and offenders. Handguns and other firearms were the weapon of choice in homicide-suicides.
