Villisca Ax Murder House in Villisca, Iowa
While this isn't a haunted house, it is a house that is haunted. A gruesome family murder still looms over this two-story home in a rural Midwestern town. Eight people died, and more than 100 years later, the case remains cold. But locals claim that its pulse refuses to die out. Available for short tours and overnight investigations, ghost hunters, psychic mediums, and spook junkies claim to have captured moving objects and apparitions on video, and have described experiencing "unexplained noises" and "an overwhelming negative energy" from the confines of its walls.
