The thesis that the closer the ties between the offender & victim in a homicide, the greater the ensuing guilt & the greater the likelihood of suicide was tested. 16,425 homicides in Chicago are analyzed. Results largely confirm the hypothesis. Controlling for sociodemographic variables, killing an ex-spouse/lover increased the risk of suicide the most, 12.68 times. Homicide-suicide is seen as stemming from a frustrated intimate relationship & a blend of self- & other-blame in attribution style.
