Villisca Axe Murder House – Villisca, IA
In 1912, six members of the Moore family (two parents and four children) along with two child houseguests were murdered in their beds. Nobody knows who did it or why. Henry Lee Moore (of no relation) was the suspect due to his similar murders but could not be pinpointed to it whatsoever. The house still stands today and the negative energy permeates the grounds. It's a hotbed for paranormal activity.
