Edmund Kemper

Edmund Emil Kemper III is an American serial killer convicted of murdering seven women, including his own mother, and one girl between May 1972 and April 1973. Years earlier, at the age of 15, Kemper had murdered his paternal grandparents. Kemper was nicknamed the "Co-ed Killer", as most of his non-familial victims were female college students hitchhiking in the vicinity of Santa Cruz County, California. Most of his murders included necrophilia, decapitation, dismemberment and possibly cannibalism.
