The owners of the house were George and Kathy Lutz. They moved into the house at Amityville after its previous owners the DeFeo's were murdered by their son, Ronald DeFeo. The Lutzes claimed that the evil that was present in the house drove Ronald to murder his entire family.

What happened was that in the early hours of the morning on November 13th, 1974. Ronald took a high powered rifle and murdered his mother, father, two brothers, and two sisters. Apparently one of his sisters awoke during the shooting only to be looking down the barrel of the shotgun and be shot dead.

Ronald DeFeo's excuses for murdering his family changed consistently, from him hearing voices to him not hearing voices to it being a Mafia hit to the older of his sisters.

After being arrested Ronald kept boasting how he would plead insanity at the court hearing and be released in a few years. Psychiatrists found that he was suffering an antisocial personality disorder, however Ronald was found sane and responsible for his actions. Everyone was shocked when they heard that DeFeo had a list of people who he was going to take revenge on after his release. It was also noted that DeFeo kept asking about his inheritance from his murdered family and how much he'd be getting from this fact it can generally be assumed that he killed his parents and family for the money he was hoping to receive from their insurance. A sad case but not the sort of thing that would cause demons to possess a house.

Ronald DeFeo was sentenced to six consecutive 25 year-to-life prison terms, he still rots in prison to this day.

The Lutzes moved in to the house in the summer of 1975. They knew about the murders but decided that it wouldn't be a problem for them and their three children. Little did they know. After living in the house for 10 days the Lutzes suddenly abandoned all their possessions and moved out of their beloved new home. They soon went public and told of horrors that went on in their house that tormented them whilst living there.

The stories they told included a demonic levitating pig, glowing red eyes that stared at them through the window, ghostly voices that tell them to "get out!",a pit into hell in the basement, oozing slime and blood from the walls, urges to repeat the murders that had happened in the house previously, infestations of flies, and waking up every night at the exact same time that the murders took place. Now I don't know about you - but having investigated quite a few real-life hauntings myself I know for a fact these things simply don't happen, the only places they seem to happen are in the minds of those who wish these things to happen for publicity and money and also in the minds of those who have seen The Exorcist and other horror films one too many times.
