THE DEATH OF A POLICE OFFICER DURING A WILD LAS VEGAS SHOOTOUT MAY HAVE BEEN CAUSED NOT BY THE CRIMINALS THEY WERE PURSUING, BUT BY ONE OF HIS FELLOW OFFICERS, ON A REBROADCAST OF "CSI: CRIME SCENE INVESTIGATION," ON A SPECIAL NIGHT, SUNDAY, MAY 7

Part One of a Two-Part Episode

"A Bullet Runs Through It, Part One" -- When a police officer is killed in the line of duty, the CSIs must determine whether or not he was a victim of friendly fire, on a rebroadcast of part one of a two-part CSI: CRIME SCENE INVESTIGATION, on a special night, Sunday, May 7 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Danny Cannon directed the episode from a script by the series� technical advisor Richard Catalani and Carol Mendelsohn, one of the series� executive producers. (Originally broadcast 11/10/05; previously scheduled for a later date)

A routine traffic stop turns into a wild police chase through the streets of Las Vegas, resulting in the death of a police officer. When all is finished, the crime scene stretches for miles and the CSIs face an avalanche of ballistic evidence in order to find the real killer of the police officer who died on the scene. Grissom fears the officer may have been the victim of "friendly fire" and not the drug criminals they were chasing.
