T02:C02 - S02:E02 - Eye Witness

An old enemy of Holloway's, and well known crime figure, Marty Miller, is responsible for the brutal slaying of a young father. Holloway's hopes of nailing Miller take a dive, however, when his main witness is scared off. Holloway's only chance is to come up with another witness, fast. Sykes is supremely confident of passing the police divers' training course. His self-assuredness leads some of his colleagues to wonder if he's riding for a fall.
