Mr. DeFeo admitted to murdering his folks and four kin in 1974 at their home in Amityville, N.Y. The house turned into the subject of books and films.
Ronald DeFeo, who was indicted for killing his folks and four kin at the family’s home in Amityville, N.Y., in 1974 — a binge that brought forth a progression of books and motion pictures, including the 1979 film “The Amityville Horror” — passed on Friday at an emergency clinic in Albany. He was 69.
The New York State Department of Corrections and Community Supervision affirmed the demise on Monday and said that the reason would be controlled by the Albany County coroner.
Mr. DeFeo, who was serving 25 years to life in jail, had been held at the Sullivan Correctional Facility in Fallsburg, N.Y., since 1975. He was moved to the Albany Medical Center for clinical consideration on Feb. 2.
Mr. DeFeo was indicted in 1975 on six checks of second-degree murder after he admitted to utilizing a rifle to lethally fire his dad, Ronald DeFeo Sr.; his mom, Louise; his sisters, Dawn and Allison; and his siblings, Mark and John Matthew.
