title: Predatory violence during mass murder.
abstract: A case of mass murder by a 35-year old male is reported. Following a week of separation from his spouse and temporary loss of custody of his son, the subject went to his wife's worksite and murdered her and the store manager, wounded a passerby in a car, and murdered a police officer arriving on the scene. Weapons used were a .32 caliber revolver, a 9-mm pistol, a 7.62-mm assault rifle, and a .50-caliber rifle. The fact pattern of the case is shown to be quite consistent with a predatory mode of aggression-violence that is planned, purposeful, emotionless, and not preceded by autonomic arousal. The forensic importance of considering mode of violence, whether predatory or affective, independently of psychiatric diagnosis, is emphasized.
