On November 13, 1973, police received a frantic phone call that led them to a nightmarish crime scene at the Defeo residence in Amityville, Long Island - an entire family had been murdered in their beds while they slept.

In the days that followed, Ronald Defeo eventually confessed to methodically killing his parents and four siblings with a rifle, saying "voices" in the house drove him to the massacre.

One year later, George and Kathy Lutz and their children moved into the house thinking it would be their dream home. But soon the voices began again. Sleepless nights. Numbing cold. Visions of a murdered little girl.

Then George began to do what the voices told him... 28 days after moving in, the Lutzes abandoned the residence - lucky to escape with their lives.

30 years after the shocking real-life events that inspired one of the most popular horror stories of all time, revisit the house that started it all: "The Amityville Horror."
