Edmund Emil Kemper III (born December 18, 1948), also known as the Co-ed Butcher or the Co-ed Killer, is an American serial killer, necrophile and suspected cannibal who committed the abduction and murder of several women in the early 1970s, as well as the murders of both of his paternal grandparents and his mother. Ottis Elwood Toole (March 5, 1947 – September 15, 1996) was an American drifter who was convicted of six counts of murder. Like his companion Henry Lee Lucas, Toole made confessions he later recanted, but which resulted in murder convictions. Gerard John Schaefer, Jr. (March 25, 1946 – December 3, 1995) was an American murderer and suspected serial killer from Florida. He was imprisoned in 1973 for murders he committed as a Martin County, Florida, Sheriff's deputy. While he was convicted of two murders, he was suspected of many others. Schaefer frequently appealed against his conviction, yet privately boasted both verbally and in writing of having murdered more than 30 women and girls.
