Edmund Emil Kemper III (born December 18, 1948), also known as The Co-ed Killer, is an American serial killer who was active in the early 1970s. He started his criminal life as a teenager by shooting both his grandparents while staying on their 17-acre ranch in North Fork, California, a crime for which he was incarcerated. Kemper later killed and dismembered six female hitchhikers in the Santa Cruz, California, area. He then murdered his mother and one of her friends before turning himself in to the authorities.
