Synopsis by Hal Erickson
Jay Leno makes a brief uncredited appearance in this first episode of a two-part story , in which the homicide unit "celebrates" the new year by going after a serial sniper who strikes every eight hours. Having already claimed nine victims, the elusive killer taunts the cops by leaving behind cryptic clues based on the old game hangman. While investigating the case, Bayliss (Kyle Secor) is hampered by back pains, leading to a potentially dangerous dependency on medication. And Barnfather (Clayton LeBouef), frustrated by the lack of progress in tracking down the sniper, takes out his frustrations on Russert (Isabella Hoffman), leading to a momentous showdown.
