The grisly tale behind the 1977 book and movie franchise The Amityville Horror began with one person: Ronald DeFeo Jr.

Ronald was the eldest child of Louise and Ronald DeFeo Sr. The three of them lived with Ronald’s four other siblings in a large house in Amityville on New York’s Long Island. You may have heard of this haunted home at the infamous 112 Ocean Avenue.

The home’s horrific history began when 23-year-old Ronald Jr. confessed to killing his parents and siblings on the morning of Nov. 13, 1974. All six of them had been murdered in their beds with a .35 caliber rifle.
