In 1974, a mass murder shook the sleepy waterfront town of Amityville, New York. One November night, police found the DeFeo family shot dead, face down in their beds. Only one survived: Ron DeFeo Jr., the eldest son with a troubled past. In this six-part series, host Donnie Wahlberg untangles the dark and complicated story of what happened that night, and unearths how these grisly murders sparked an infamous haunted tale.
