Despite being a popular tourist destination, the house is private property owned by one of Rehmeyer's descendants, and has ADT security systems installed.
In November 1928, under the malicious advice of a woman named Emma Knopp (more commonly known as Nellie Noll due to a work of fiction), John Blymire believed that he had been cursed by Nelson Rehmeyer, a practitioner of powwow.
On November 27, 1928, Blymire and his accomplices called on Rehmeyer at his home hoping to find his copy of the powwow book the Long Lost Friend and also get a lock of his hair.
Knopp advised him to burn the book and bury the lock of hair eight feet underground.
