This episode of “20/20” airs tonight July 21 at 9PM ET. An all-new “20/20” reports.

In 1968, Rodney Alcala lured a young girl outside the iconic Chateau Marmont hotel in Hollywood and into his car, which marked the beginning of his reign of cross-country attacks that spanned over a decade. Posing as a professional photographer, Alcala often used his good looks and charm to trap his victims. But perhaps his most brazen move came in 1978 when he made a chilling appearance as a contestant on the hit show “The Dating Game” and won. Through first-hand accounts from investigators, victims, eyewitnesses and even his court-appointed psychologist, “20/20” reports on one of the most notorious serial killers of modern times.

The two-hour program features interviews with Tali Shapiro, who miraculously survived an attack by Alcala when she was just 8 years old; Chris Camacho, a former LAPD officer who saved Shapiro’s life; Jed Mills, who sat beside Alcala on “The Dating Game” as a fellow contestant; Gina Satriano, a Los Angeles prosecutor; Matt Murphy, an Orange County prosecutor and ABC News contributor; and victims’ family members. The episode also features the 2013 interrogation of Alcala by Wyoming authorities about his alleged role in the murder of Christine Thornton 36 years earlier, which he denies.
