Henry Lee Lucas

Ottis Toole was long linked to the 1981 killing of Adam Walsh, which he confessed to only to later recant. He reportedly admitted to it one final time on his deathbed. 

Henry Lee Lucas claimed he killed over 600 people — but Vic Feazell was instrumental in disproving that, as shown in Netflix's docu-series "The Confession Killer."

"The Confession Killer" tells the story of Henry Lee Lucas, who confessed to hundreds of murders, closing cases that should have remained open.
