Harvey Murray Glatman was known in the media as the Lonely Hearts Killer and the Glamour Girl Slayer. Judy was his first known victim.
He would use several pseudonyms, posing as a professional photographer to lure his victims with the promise of a modeling career.
Glatman’s crimes spanned miles and more than one county, but he was turned over to San Diego County for prosecution in the slayings of Shirley Bridgeford and Ruth Mercado. Against the advice of his mother and his attorney, who wanted him to plead insanity, Harvey entered a plea of guilty and eloquently argued for his own execution.
“I think,” he said, “the guilty please was proper. If I don’t think these people (his attorney and his mother) really believe I am or was inane. This is just a delaying maneuver. My actions justify my previous plea. I would reather be executed than spend the rest of my life behind bars.”
