THE REAL AMITYVILLE HORROR: The True Story Behind The Brutal DeFeo Murders Settled in an affluent neighborhood in Long Island, New York is the one of the most infamous houses in all of America, or perhaps the world. The house with the iconic double-windows, white siding, and chimney at 112 Ocean Avenue is the home to the one of the most horrific family massacres in history, as well as an infamous haunting hoax. The haunting of the Amityville house is much more prominently known than the murders that took place in the same house. The Amityville or DeFeo family murders committed by Ronald "Butch" DeFeo Jr. have gone down in both true crime and pop culture history. The book and the subsequent horror film series about the case continue to fascinate and fear audiences years later. Both cases are clouded in unreliable testimony, profiteering, admitted fabrication, and greed. This is the real story of what happened at Amityville, and the events leading up to this horrific crime.
