Major differences are observed between, on one hand, sexual homicides and, on the other hand, nonsexual homicides and violent sexual assaults. These differences focus mainly on the offender and modus operandi characteristics.

Findings present implications in terms of correctional practices, offender treatment, and rehabilitation.
