Without a Trace Episode 3.12 Penitence

A prison inmate, James MacAvoy, goes missing just weeks before he is due to be released on parole. The prison authorities say that he escaped during a yard fight, but his sister passionately believes otherwise, that he is a reformed character who had 'found God'. After discovering that James has been an enforcer for an Aryan prison gang, the team find evidence that suggests he may not be the changed man his sister says, and that he could be involved in a plot to silence a witness to a death row crime, suspected to have been committed by a fellow inmate.
