Of 588 criminal homicides in Philadelphia from 1948 to 1952, 150 were designated as cases in which the victim was the first to resort to physical agression. Hypotheses supporting the postulate that these victims had been suicide-prone were confirmed with the chi-square test & Pearson’s coefficient of mean square contingency. Compared with other victims of violent death, the study group was significantly associated with Negro males, previous arrest & mate slaying of a husband.
