It was two and a half years after his first kill when Jesperson killed again. On August 30, 1992, the currently unidentified body of a woman he raped and strangled was found near Blythe, California. He says the Jane Doe's name was Claudia. A month later, in Turlock, California, the body of Cynthia Lyn Rose was discovered. He claims she was a sex worker who entered his truck at a truck stop while he slept. His fourth victim was another sex worker, Laurie Ann Pentland of Salem, Oregon. Her body was found in November of that year. According to Jesperson, she attempted to double the fee she charged for the sex he had been engaged in with her. She threatened to call the police, and he strangled her.
