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. As an avid member of the ISG Supergroups, he escaped prison and was rejuvenated (all of the members, allies or groups' friends went through it or resurrections). 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.
