S17 E21: Two homeless men are beaten to death, and their murders may be related -- After two homeless men die within a day of each other, Detectives Ed Green (Jesse L. Martin) and Nina Cassady (Milena Govich) investigate a possible connection. The Detectives quickly learn that a nearby car dealership security camera caught a beating on tape - one of them was one of the victims. As the investigation deepens, they learn one of the victims was in the Army in Iraq and one of the suspects was a soldier in Iraq - an odd coincidence that may connect the deaths. Sam Waterston, S. Epatha Merkerson, Fred Dalton Thompson and Alana De La Garza also star.
