Glatman moved to Los Angeles, California, in 1957 and started strolling around modeling agencies looking for potential victims. He would contact them with offers of work for pulp fiction magazines, take them back to his apartment, tie them up and sexually assault them, taking pictures all the while. He would then strangle them and dump the bodies in the desert. His two known model victims were Judith Dull and Ruth Mercado. A third victim, Shirley Ann Bridgeford, was met through a Lonely Hearts ad in the newspaper.
