MORE INFO: Thor Nis Christiansen was a Danish-American serial killer who targeted young women of similar appearance in Isla Vista, California, an area with a large student population, causing panic that there was a 'lookalike killer' on the loose. Between 1976 and 1979, Thor killed four girls who were out hitchhiking, lured them into his car and shot them. A fifth intended victim, Lydia Preston, managed to escape from Thor's vehicle with severe injuries after she was shot in the head.
With little progress being made tracking down The Lookalike Killer, things took a significant turn when Lydia spotted Thor in a Hollywood bar three months later and reported him to police. He was arrested and linked to the Isla Vista, murders, tried and sentenced to life in prison. Thor, aged 23, was stabbed to death by a fellow inmate in the exercise yard at Folsom State Prison after serving less than 10 months. His killer was never identified.
