No one disputes the atrocity of the 1974 murders committed by Ronald DeFeo Jr which occurred at the house. However, was there any truth to the 1977 book by Jay Anson which chronicled various claims by George and Kathy Lutz that:
Slime oozed from the walls?
Locks and windows were broken by an unseen force?
Cloven hoofprints unexplainedly appeared outside in the snow on January 1, 1976?
Or that the "most famous haunted house in America" was actually haunted?
