One of the most sensational and controverial cases of alleged evil presences. Perhaps the most famous haunting story in America, Amityville is a town in Suffolk County, New York. The town is well-known for the "Amityville Horror" - a story based on the mass murder of the DeFeo family in 1974 and the Lutz family who bought the house in 1975, only to flee a year later, claiming they had been terrorized for 28 days by ghostly spirits. Amityville horror became a self-titled best selling novel and motion picture.
The Amityville horror might go back to 1644 and a land curse. Tackapausha, the chief of the Massapequa Indians had sold use of the land of what is now Long Island to the Dutch for settlement. The Dutch wanted the land itself, so they hired Indian fighter Captain John Underhill, who in a massacre killed over 120 Indians and buried them in a mass grave in Fort Neck. Fort Neck is about a mile away from 112 Ocean Avenue - the street and house where the DeFeo family lived.
Butch DeFeo, who killed his siblings and parents, claimed he had been possessed by an Indian chief.BoM, p.27ff
