THE CSI TEAM INVESTIGATES TWO DIFFERENT MURDER CASES WHERE ALL OF THE SUSPECTS AND VICTIMS ARE LAW ENFORCEMENT OFFICERS, ON A REBROADCAST OF "CSI: CRIME SCENE INVESTIGATION," ON A SPECIAL TIME, THURSDAY, FEB. 3 AT 8:00 PM

"Dead Ringer" -- The CSI team is busy trying to get to the bottom of two murders that happen during the annual law enforcement running race in Las Vegas, one where a runner is found dead while competing and the other back at the hotel where two police officers are found murdered on a rebroadcast of CSI: CRIME SCENE INVESTIGATION Thursday, Feb. 3 (8:00-9:00 PM, ET/PT) on the CBS Television Network. Ken Fink directed the episode from a script by Elizabeth Devine. (Originally broadcast 4/29/04)

The CSI graveyard shift competes in the annual law enforcement running race until they discover a runner found dead in the desert. Their murder investigation becomes dicey when all of the suspects/participants are cops. Meanwhile, Sara and Warrick investigate what initially appears to be a murder/suicide involving two other police officers, until the evidence suggests they've both been murdered.
