In 1980, a Danish-American serial killer Thor Nis Christiansen was sentenced to life in prison for killing 4 women (three of which had a similar appearance) between November 20, 1976, and April 18, 1979.

Christiansen had been captured after his fifth intended victim, Lydia Preston, escaped with a bullet in her head. On July 11, 1979, Preston accidentally met Christiansen in the Bottom Line Bar in Hollywood and reported him to police, who promptly arrested him. After the arrest, Santa Barbara County investigators realized they had investigated Christiansen as a suspect in 1977.

On March 30, 1981, Christiansen was found dead in the exercise yard at Folsom State Prison with a single stab wound in his chest. To this day, his killer is still unidentified, although psychiatrists had warned that Christiansen would be in danger in prison, due to the sexual nature of his murders, and his youthful, blond appearance.
