Suicide was a character in The Return of the Living Dead.
He was portrayed by the late Mark Venturini
Suicide was a friend of the group of punks and not well liked by any of them. They would only hang out with Suicide if they needed a ride somewhere. He drove a "beat-up" 1960 Cadillac Series 62 convertible, covered in graffiti with no windows and a knocking engine. Suicide was the first to die after blindly running into the basement, to find/help Tina who he (and the group of punks) heard screaming, where his brains were then eaten by Tarman. Because he was never exposed to high amounts of Trioxin, his corpse never reanimated.
His body was later found by Burt and the other surviving punks.
