Belle Sorenson Gunness was a Norwegian-American serial killer. The physically very strong woman killed most of her suitors and boyfriends, and her two daughters. She may also have killed all of her children and both of her husbands, on different occasions. Her motive was collecting life insurance benefits… and also, the assets stolen or swindled from her suitors became her source of income. Some reports estimate that Gunness killed over 40 people over several decades and most of them were poisoned. Gunness was never caught for the murders and what happened to her was never known. On the record, her death is listed as April 1908, the last time she was seen alive.
