Multiple homicide offenders: Offense characteristics, social correlates, and criminal careers

Because investigations of multiple homicide offenders (MHOs) are usually case studies, there is limited understanding of the linkages between them and other criminal offenders. Using data from an exploratory sample of 160 MHOs and a control group of 494 single homicide offenders, this study examines MHOs from a criminal career perspective and finds that nearly 30 % of them were habitual offenders before their final homicide event. Those with prior rape convictions, misdemeanor convictions, more extensive prison histories, and current involve-ment in rape and burglary are more likely to kill multiple victims. Curiously, nearly 40% of MHOs had zero prior arrests. Overall, arrest onset occurs later in the life course and is not predictive of offending. In conclusion, the study of MHOs could enrich the criminal career perspective, while posing some empirical and theoretical challenges to that paradigm
