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, New York.
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.
Beginning in 2011, there was a resurgence of low-budget direct-to-video independent films based on or loosely inspired by the Amityville events.
