Ottis Toole

Initially convicted of three counts of murder, later pleading guilty to four more murders before dying in prison. A sometime accomplice of convicted serial killer Henry Lee Lucas, Toole admitted to-and retracted multiple times-over 100 counts of murder, rape, arson and cannibalism, and was the suspect in several other unsolved murders. In 2008, police announced that they had identified Toole as the likely murderer of Adam Walsh, and would be closing the case as a result.
