A former thief who spent seven years in prison kills the man who ratted on him. Unfortunately, he gets T-boned by a young woman as he is leaving the scene. She makes the mistake of trying to call the police and he breaks her neck. He is a skilled criminal and has had great success covering his tracks and setting up distractions. Ultimately, it's the diligence of the CSI's, looking at little things, that starts the ball rolling. Good episode.
