A serial “black widow,” Lyda Southard married seven men in five states over the course of eight years. Between 1915 and 1920, four of her husbands, a brother-in-law, and Southard’s three-year-old daughter — all recently covered by life insurance policies at Southard’s suggestion — died only months after the nuptials, apparently of ptomaine poisoning, typhoid fever, influenza, or diphtheria. Southard was convicted of second-degree murder in the poisoning death of her first husband, earning her a ten-years-to-life sentence in the Old Idaho State Penitentiary. She escaped with the warden’s assistance in 1931, only to be recaptured and returned to serve another eleven years before receiving parole. After changing her name and divorcing three times, she died of a heart attack in 1958 in Salt Lake City, Utah.
