On November 13, 1974, police received a report of a homicide at 112 Ocean Avenue in the Village of Amityville, New York, a sleepy seaside community located on Long Island's South Shore. Once there, the police discovered six members of the DeFeo family -- father, mother and four of their five children -- shot and killed execution style. The surviving son, Ronald "Butch" DeFeo Jr., was eventually charged and tried for the murder of his family and now is serving six concurrent life sentences. Some said a strong supernatural force in the DeFeo home drove Butch DeFeo to kill his family, while others claimed Butch DeFeo killed to receive an inheritance. The Night the DeFeos Died offers the true story behind this tragedy and exposes Butch DeFeo did not act alone in the commission of this crime. It also shows that the supernatural stories created about the famed Amityville house were nothing, but a ruse concocted for Butch DeFeo's defense that later grew into a cottage industry. The whole truth regarding the story has never been revealed, until the publication of Ric Osuna's book. From mob involvement to a corrupt judicial system, The Night the DeFeos Died reveals the full details of the DeFeo murders, including how they were a culmination of substance abuse and domestic violence.
