Ottis Toole was an American serial killer who was charged for three counts of murder, but confessed to four more after being incarcerated. He is also known for his relationship with fellow serial killer, Henry Lee Lucas; his paranoid schizophrenia; and for the posthumous indictment for the murder of Adam Walsh (the son of John Walsh, host of America’s Most Wanted). Toole died in 1996 of liver failure while in prison.
