The term "Amityville" primarily refers to the small town in New York, known for its infamous history related to the Amityville Horror. In 1974, a tragic mass murder occurred when Ronald DeFeo Jr. killed six members of his family in their home at 112 Ocean Avenue. This event drew significant media attention and led to various investigations. Following the murders, the house was purchased by the Lutz family, who reported experiencing paranormal activities. Their experiences inspired the book "The Amityville Horror," which was later adapted into several films. The story has since become a significant part of American horror culture.
