“Dating Game” winning bachelor went on to be serial killer
Sociopaths are often glib and charming. Rodney Alcala was no exception. He appeared on the Dating Game in 1978, and his suggestive answers ("What's your best time?" she said. "The best time is at night," Alcala answered with a wide smile. "Nighttime.") before Bachelor #1 made him the top pick of the young woman seeking a date. He has recently convicted of murdering five young women and girls.
The Dating Game must not have done a very good job of vetting their contestants, because 10 years before he had appeared on the show Alcala had been convicted of raping an 8-year-old.
