On November 14, 1974, police received a frantic phone call that led them to a grisly crime scene at the Defeo residence in Amityville, Long Island – an entire family had been slaughtered in their beds. In the days that followed, Ronald Defeo confessed to methodically shooting his parents and four siblings while they slept. He claimed "voices" in the house drove him to commit the murders. One year later, George and Kathy Lutz and their children moved into the house thinking it would be their dream home. But shortly after settling in, bizarre and unexplainable events began to occur – nightmarish visions and haunting voices from an evil presence still lurking within the house. 28 days after moving in, the Lutzes abandoned the home, lucky to escape with their lives. Now, 30 years after the shocking real-life events that inspired one of the most popular horror stories of all time, return to the house that started it all: "The Amityville Horror".
