Thornton is an officer and character in Friday the 13th Part VI: Jason Lives.
He is the 51st victim of Jason Voorhees.
Thornton is a minor character in Jason Lives, appearing as backup with Officer Pappas when Sheriff Mike Garris goes to search Camp Crystal Lake for the missing Tommy Jarvis, wrongly convicted of several recent murders. Thornton separates from the group and goes to investigate the docks, and while searching the nearby bushes, shines his flashlight directly onto Jason Voorhees. Thornton reaches for his gun, but Jason flings a dart at the Officer, piercing his skull and knocking him into a nearby dingy.
