After being discharged from the U.S. Navy after World War II, Ed Warren was an itinerant house and sign painter traveling around New England. However, with his wife Lorraine Warren, née Lorraine Moran, he became known as a demonologist employed in investigating reports of haunted houses. They attained national renown in 1975 when they wrote up their reports of their investigation of the George Lutz house in Amityville, Long Island, New York. The Lutz family moved into the house, which had been the site of the murder of five members of the DeFeo family the previous year. The Lutz family moved out after 28 days, claiming that they had been chased out by ghosts and other demons. Although some felt that the story was a hoax, the Warrens swore that, after their investigation, the house was haunted. The Warrens were the founders of the New England Society for Psychic Research.
