"Living Legend" -- Grissom and his team investigate a string of murders in Las Vegas that may be tied to an infamous mob boss from the 1970s who disappeared many years ago, on a rebroadcast of CSI: CRIME SCENE INVESTIGATION, Thursday, May 31 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Martha Coolidge directed the episode from a teleplay by Douglas Petrie and a story by Douglas Petrie and Carol Mendelsohn, one of the series' executive producers. (Originally broadcast 11/23/06)

Grammy Award and Golden Globe Award nominee Roger Daltrey ("The Who Live, Featuring the Rock Opera Tommy," "Tommy"), the legendary lead singer of the rock group The Who, guest stars in a mystery role.

After the mob boss's Cadillac mysteriously resurfaces in a Las Vegas lake and a photo turns up of the murder victims posing with him in the 1970s, the CSIs begin to investigate whether or not the notorious gangster, whose disappearance remains a mystery, might somehow be connected to the current killing spree in Las Vegas.
