Mallika: Currently serving a life sentence after being convicted of 6 counts of murders, Mallika is considered to be the first female serial killer. She would pretend to be someone well-versed in rituals and befriend women in temples, and later call them to another temple far away in a secluded location. The victims would be requested to show up in their fineries. Mallika would then ask them to consume cyanide-laced holy water or prasad. She would then take off with their valuables. Pic/YouTube
