Court records show Williams lived at 509 Fulton Avenue in 1981. He was convicted for murdering a man at a Hawkins County house on January 12 that same year. Williams severed the head and torso from the victim’s body, and then used liquid accelerant to burn the house down.

Williams was granted parole in 2009. According to the Tennessee Department of Corrections, his parole was revoked in 2011 for a technical violation, but reinstated in March 2012.
