The Amityville haunting is a modern folk story based on the true crimes of Ronald DeFeo Jr. On November 13, 1974, DeFeo shot and killed six members of his family at 112 Ocean Avenue, Amityville, on the south shore of Long Island. He was convicted of second-degree murder in November 1975. In December 1975, George and Kathy Lutz and their three children moved into the house. After 28 days, the Lutzes left the house, claiming to have been terrorized by paranormal phenomena while living there. The house became the subject of numerous investigations by paranormal researchers, journalists, and skeptics, including Ed and Lorraine Warren. These events served as the historical basis for Jay Anson's 1977 novel The Amityville Horror, which was followed by a number of sequels and was adapted into a film of the same name in 1979. Since then, many films have been produced that draw explicitly, to a greater or lesser extent, from these historical and literary sources. As Amityville is a real town and the stories of DeFeo and the Lutzes are historical, there can be no proprietary relationship to the underlying story elements associated with the Amityville haunting. As a result of this, there has been no restriction on the exploitation of the story by film producers, which is the reason that most of these films share no continuity, were produced by different companies, and tell widely varying stories.
