Stuart McCallum is a minor prisoner in Oz. Portrayed by Tom Farrell.
McCallum only appears once in the show, as a dead body. Nothing is known about him except his name. It can also be assumed that he is violent, since he stays in solitary.
He is one of the inmates in solitary. He commits suicide by eating pieces of his own flesh, which made him bleed to death. He is found by Officer Claire Howell and another CO. Because of McCallum's death, Warden Leo Glynn decides to allow the prisoners in solitary to receive some controlled recreation time in the gym.
