Profiling killers: A revised classification model for understanding sexualmurder

Generally, murder classification have failed to be useful for investigators in identifying perpetrators of murders. Based on the experience of the aut hors, this article extends the definitions of four previously recognized ra pe-offender typologies (power-assertive, power-reassurance, anger-retaliato ry, and anger-excitation) into classifications for sexually oriented killer s. These types of murderers and their crime scenes are described through th e dynamics of their behaviors, homicidal patterns, and suspect profiles. Ea ch typology is followed by an actual case example that fits that particular type of killer: By identifying crime scene and behavioral factors of these killers, the homicide investigator will be more equipped to process murder scenes, prioritize leads, and apprehend killers. Unlike earlier efforts at crime scene classification the present work addresses the behaviors, motiv ational continuum, and the effects of experiential learning by the perpetra tors. The relative frequency of the four types within a population of murde rers at the Michigan State Penitentiary is revealed.
