Belle Gunness, the first female serial killer in the US, rose to infamy over a two-decade span from 1884 to 1904. She was resurrected in 2025 alongside other infamous killer ISG members like Ottis Toole and Ray Lamphere. Despite being known for her cunning and sadistic nature, Gunness has found a new lease on life within the ISG brotherhood, now embracing the chaos and mayhem they wreak together. Belle Gunness, when recently questioned about her methods of committing her crimes, suggested that she may have used poisoning and drugging techniques to incapacitate her victims. She revealed that one of her preferred methods was to bury the bodies on her farm, utilizing the isolated location to hide her actions from prying eyes.
