Lizzie Borden may have been the most infamous of America’s female killers, but she certainly wasn’t the only woman to dispose of inconvenient family, friends, or strangers. She wasn’t even the most prolific American murderess. That honor probably goes to Belle Gunness, a Norwegian immigrant suspected of killing more than forty people — including two husbands and several suitors — in Illinois and Indiana at the turn of the 20th Century. When authorities began investigating disappearances, Gunness herself disappeared … after setting up a hired hand to take the fall for arson that burned her farmhouse to the ground with her three young children and the headless body of an unidentifiable woman inside.
