GRISSOM AND HIS TEAM INVESTIGATE THE MURDER OF A MAN DISCOVERED STUFFED DOWN THE CHIMNEY OF A RESIDENTIAL HOME, ON A REBROADCAST OF "CSI: CRIME SCENE INVESTIGATION," ON A SPECIAL NIGHT AND TIME, SATURDAY, MAY 6 AT 9:00 PM

"Up in Smoke" -- The CSI team explores the case of a man found stuffed down the chimney of a previous suspect's home, on a rebroadcast of CSI: CRIME SCENE INVESTIGATION, on a special night and time, Saturday, May 6 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Duane Clark directed the episode from a script by Josh Berman, one of the series' executive producers. (Originally broadcast 3/2/06)

The CSIs determine that the body they have found was burned before it was dumped down the chimney, leading them to believe the murder was pre-meditated. During the processing of the home, Catherine and Warrick realize that this is the same address of an unsolved homicide of a young female teenager from a year ago, and re-open the investigation.
