Rodney James Alcala was a lady-killer — literally. The outwardly charming Alcala landed a spot on The Dating Game in 1978 while in the middle of his murderous reign, later earning him the nickname "The Dating Game Killer." Alcala was eventually given the death sentence by the state of California for the murder of five people. The killer himself, though, says that number is low. He claims that he raped, tortured, and murdered well over 100 victims.
