Eight people (including six children) were murdered in the Villisca house of Iowa in 1912. All of the victims were bludgeoned to death with an ax.
The murder at the Villisca house remains unsolved. The house is now haunted by the victims — EVPs have picked up young girls' screams and a voice saying, "Boo!"
One paranormal investigator sat in the sewing room of the Villisca house where the temperature of the room dropped so low that he could see his own breath within minutes. Scary!
You can book an overnight tour in the house and see if you can witness any paranormal activity for yourself. Many visitors have witnessed the presence of ghosts.
