Henry Lee Lucas, also known as The Confession Killer, was an American convicted murderer. Lucas was convicted of murdering his mother in 1960 and two others in 1983. He rose to infamy as a claimed serial killer while incarcerated for these crimes when he falsely confessed to approximately 600 other murders to Texas Rangers and other law enforcement officials. Many unsolved cases were closed based on the confessions and the murders officially attributed to Lucas. He was convicted of murdering 11 people and condemned to death for a single case with a then-unidentified victim, later identified as Debra Jackson.
