When twenty-seven-year-old James Bullock was shot and killed in St. Louis in the winter of 1958, investigators immediately focused their attention on Bullock’s wife, Edna, who was the beneficiary of her husband’s large life insurance policy. Witnesses recalled seeing the victim being chased by a man with a gun on the night of the murder, and detectives suspected Edna had arranged for her husband to be killed so she could collect the insurance money. They didn’t know it at the time, but St. Louis investigators were investigating what was to be the first victim in a decades-long career of a most unlikely hitman and serial killer.

Although they had their suspicions that Edna Bullock had enlisted the help of her ex-husband, Glen Engleman, in the murder of her new husband, it would take many more years before those suspicions were confirmed. And by that time, Engleman, a successful suburban dentist had taken the lives of several more people, all to satisfy his own interest in calculated and carefully planned assassinations.
