Dyadic death: a typology.

In dyadic deaths, a second victim acts in consort with, is associated with, or is killed by a person who, contemporaneous with the first death, then suicides. Dyadic deaths thus include both homicide-suicides and suicide pacts. This paper describes, suggests organizing dynamics of, and illustrates distinct types of dyadic deaths. The proposed typology varies by levels of dominance, dependence-enmeshment, and the presence or absence of hostility in and between partners.
