A case of stalking in the workplace and subsequent sexual homicide by a 33-year-old male is reported. Following several months of stalking a 38-year-old female, the male subject went to the woman's office after business hours and restrained, raped, and murdered her. The cause of death was multiple stab wounds. The facts of the case reveal that the subject fits a predatory-type stalker, which represents a small subgroup within stalkers that has received little attention. Unlike other types of stalkers, the predatory stalker gives little warning to their victim (or multiple victims), as their stalking behaviors tend not to be very invasive or harassing. In general, most stalkers are not physically violent; however, predatory-type stalkers, given their tendency for sexual violence, are dangerous and the importance of identifying them is emphasized. Factors associated with perpetrators of sexual homicide are discussed.
