Even as Rodney Alcala was becoming one of California's most notorious serial killers, he was a winner of a 1978 episode of TV's "The Dating Game." Alcala posed as a professional fashion photographer in Los Angeles to lure his female victims to their deaths. He now sits on death row for 5 torture murders in California and he also admitted to killing another 2 women in New York. The actual number of his victims may never be known. Nancy Grace explores the Alcala's killings with criminal profiler Pat Brown, forensics expert Joseph Scott Morgan, Los Angeles psycho analyst Dr. Bethany Marshall, and Crime Stories contributing reporter John Lemley.
