In 1974, Police received a 911 call leading them to the DeFeo house, where Ronald Defeo Jr. killed his entire family. One year later, George and Kathy Lutz move in with their family into the same house, only to stay 28 days.

I suspect you're talking about the family of Ronald DeFeo, Jr. DeFeo murdered his mother, father, and four siblings, at first attempting to blame a mob hit man, but he later confessed to the killings. (The "mob hit man" explanation is slightly more plausible than it might seem... DeFeo's great-uncle was a fairly high-ranking member in the Genovese crime family.)
