Another female murderer, Belle Gunness immigrated from Norway to the United States in 1881. Once in the United States, Gunness was at the center of several suspicious fires and deaths, including her first husband’s death of heart failure, the death of two children who may have been poisoned as infants, the infant daughter of Gunness’ second husband, and then Gunness’ second husband, himself. Gunness started posting notices in a local column, enticing suitors to her Indiana farm, after which they disappeared. She’s believed to have murdered more than 40 people, but disappeared and was never located.
