14. The Amityville Horror House
In 1974, 23 year old Ronald DeFeo killed his parents and four siblings in their home in Amityville, New York. DeFeo, the oldest of the five children, shot his entire family as they slept. His siblings, aged 9-18, had all been shot once, while the parents had been shot twice. DeFeo’s motives for the murder are unclear as his story has changed over the years. He is still in prison serving his life sentence.
The house still stands today and was recently listed for $850,000.
