Commentary: Homicide-suicide in older adults--cultural and contextual perspectives.

The authors comment on "Domestic Homicide and Homicide-Suicide: The Older Offender" by Bourget et al., who learned that after a domestic homicide in Canada, the older offender frequently commits suicide. The authors comment on the ubiquity of single homicide-suicide across cultures, the incidence of single homicide-suicide in various cultures, the common patterns and differences in single homicide-suicides across cultures, ethnic and gender differences in single homicide-suicide within different cultures, characteristics of the phenomenon of mass murder followed by suicide and ethnic differences within this type of homicide-suicide, and differences in suicidal patterns in different cultures. Suicide and suicide preceded by homicide (single or multiple) are so rare, it is currently impossible to draw any substantive conclusions about the incidence of these phenomena in various contexts; however, ideas for consideration in addressing homicide-suicide are provided.
