The real life Amityville case

The only truth to the story is the DeFeo murders and the Lutzes buying the house. You can find a That's Incredible segment on youtube that is filmed in the house with a family currently living there.

They prove many things like doors coming off hinges or banisters coming out of the ground never happened. They also interview a neighborhood girl who use to play with the DeFeos in the infamous red room which she showed wan't hidden or mysterious.

It's a great haunted house tale and fun movie but it's fiction.
