Doesn't anyone do their research anymore? The Amityville haunting (or not, depending on what side of the camp you are on) has never been "revealed to be a hoax". No, the individuals who lived in the house - the Lutzs - stuck by their story 100%, despite going through a divorce, until the day they died.
And anyone with half a brain knows that Ric Osuna is about as legitimate as a three dollar bill.
