Ottis Elwood Toole (March 5, 1947 – September 15, 1996), sometimes misspelled as Otis, was an American serial killer and arsonist. He was an accomplice of convicted serial killer Henry Lee Lucas.
Toole admitted to multiple counts of murder, rape, and cannibalism, and was the suspect in several unsolved murders. He recanted and restated a number of confessions. Toole was convicted of three counts of murder, and confessed to four more murder charges before dying in prison. On December 16, 2008, police announced that they had identified Toole as the likely murderer of Adam Walsh, and closed the case as a result.
