Belle Gunness story documentary, This horrifying story is all about Belle Gunness, a 6 feet tall lady weighing 200 pounds during the 1800s, who turned the crime of killing people into an art. It has been reported that during her entire course of life Belle killed almost 24 to 40 people who used to stay around her. The most “fascinating” part is all her victims used to be either her poor husbands and suitors or her own children. The most frustrating part is that she was never caught or punished for her “noble” works during her entire life. No doubt, this lady can be entitled as one of the most notorious assassins of America.
