Henry Lee Lucas was an American serial killer whose crimes spanned from 1960 to 1983. He was convicted of murdering 11 people and sentenced to death for the murder of Debra Jackson, though his sentence was commuted to life imprisonment in 1998. On June 5, 1983, Henry Lee Lucas was arrested for the unauthorized possession of a handgun. The police believed that he was linked to the disappearance of two females, so they used the opportunity to apply pressure and encourage a confession. After four days in custody, Lucas confessed to killing the two women.
