The Amityville Horror

Published in 1977 by Jay Anson and based on the real life events surrounding the Lutz family's takeover of the titular house after the murder of the DeFeo family it was turned into a movie soon after in 1979. The movie was directed by Stuart Rosenberg with the screenplay by Sandor Stern, and starred James Brolin and Margot Kidder.

It's a short episode this month. When it comes to the references to real life events most of the timeline was compiled using the Wikipedia page for the novel. A few side searches yielded results but most of it was the casual curiosity that started and ended with wiki.
