Tina Marie Risico went to the Hickory Farms store in the Del Amo Fashion Store in Torrance, California, on April 4, 1984. She went there to apply for a job while she was a student at Shery High School. Christopher Wilder reportedly approached her there with cameras around his neck. He then complimented her and claimed he had connections with a modeling agency. Wilder went on to lure her into his car by telling her he could help her. Christopher Wilder then stopped in the Anaheim woods before they walked to a wooded area. The Beauty Queen Killer then pulled out a gun and forced her to strip naked before he put a hat and sunglasses on her. He also taped her face before he drove her to a hotel. At the hotel, he sexually abused her using electric shocks and tortured her with a knife. He also coerced her into engaging in sexual acts. Eventually, Wilder also made Tina Marie Risico help him with committing the crimes. She reportedly approached a girl in Gary, Indiana, and told her about a modeling show before Christopher Wilder told her the same. He then lured the girl into his car, and they drove to a nearby motel when Risico reportedly watched as Wilder sexually assaulted the girl. He then electrocuted the girl and took her into the woods. Wilder suffocated her and stabbed her in the lungs before he left her there to die. However, the girl managed to draw attention from a passing car and was taken to a hospital, where she survived.
