Edmund Emil "Ed" Kemper III, a.k.a. "The Co-Ed Killer" or "The Co-Ed Butcher", is an American abuser and necrophilic, ephebophilic, and cannibalistic serial/spree killer active in the early 1970s. His murders coincided with those of another California serial killer, Herbert Mullin. Kemper targeted women, most of whom were co-eds aged in their teens to mid-twenties, most of whom attended the same college his mother worked at. All victims during his serial killer period, with the exception of his mother and Sally Hallett, were hitchhikers who were given rides by him when he cruised around. After taking them somewhere secluded, chatting them up on the way, he would kill them in various ways, including shooting, stabbing, and strangling, etc.
