Glatman also is a suspect in the slaying of “Boulder Jane Doe,” a victim whose corpse was discovered by hikers near Boulder, Colorado in 1954. Her identity remained a mystery for 55 years. In October 2009, the Sheriff’s Office was notified by Dr. Terry Melton, of Mitotyping Technologies in State College, Pennsylvania that her lab had made a match between the Jane Doe’s DNA profile and that of a woman who thought the unidentified murder victim might be her long-lost sister. The positive identification of “Boulder Jane Doe” was an 18-year-old woman from Phoenix, Arizona named Dorothy Gay Howard.

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.

Glatman was arrested in 1958, caught in the act of kidnapping what would have been his fourth known murder victim, Lorraine Vigil. A patrolman saw him struggling with a woman at the side of the road and arrested him. He willingly confessed to his three murders and eventually led the police to a toolbox containing pictures that he had taken of the victims.

He was found guilty of two counts of first-degree murder and sentenced to death, a sentence that he accepted willingly. He specifically asked the warden to do nothing to save his life. He was executed in the gas chamber of San Quentin State Prison on September 18, 1959.
