(CNN) -- Before he was a convicted serial killer, Rodney Alcala was a winning bachelor on "The Dating Game." "Oh yeah, I remember it quite clearly," said Jed Mills, the game-show contestant who sat next to Alcala in 1978. Definitely creepy." Found guilty in February of murdering four women and a child, Alcala, 66, is acting as his own attorney in the penalty phase of the trial.
He is hoping to persuade the jury in Santa Ana, California, to spare his life.
Here is a man portraying himself as a desirable young man when he is a violent sexual predator of children." Alcala's real identity revealed itself off the stage when he was with the other bachelors, Brown believes.
When he was 12, he, his mother Anna Maria Gutierrez, and his sisters, Christine and Marie, had moved to suburban Los Angeles. In the summer, he worked as a counselor at a drama camp for children in New Hampshire.
Alcala's first known victim was an eight-year-old girl named Tali Shapiro, whom he abducted as she was on her way to school.
The crimes Alcala committed date to the late 1970s.
Nobody at the time knew the man with the wavy long hair and toothy grin was an apparent psychopath -- an unstable, antisocial personality.
When they knocked on the door, he escaped out the back and evaded arrest. In 1971, Alcala is believed to have raped and strangled Cornelia Crilley, a Trans World Airlines flight attendant, in her Manhattan apartment.
