Amityville, N.Y., the site of a murder that involved Mr. DeFeo’s parents and four siblings. The house was subsequently the subject of books and movies.
In 1974, Ronald DeFeo Jr., of Amityville, N.Y., was convicted of killing his parents and four siblings.
The serial killer who inspired a series of books and movies, including the 1979 movie “The Amityville Horror,” — was said to have died on Friday in Albany at the age of 69.
The death was confirmed by New York State Department of Corrections and Community Supervision on Monday. In their statement, the Albany County coroner would identify the cause of death.
Since 1975, Ronald has been imprisoned at the Sullivan Correctional Facility in Fallsburg, New York. It was on Feb. 2 that he was transferred to the Albany Medical Center for medical care.
During the trial in 1975, Ronald confessed to using a rifle to fatally shoot his family. Six counts of second-degree murder were ruled against him. He killed his father, Ronald DeFeo Sr., his mother, Louise, his brothers, Mark and John Matthew, his sisters, Dawn and Allison.
On Nov. 13, 1974, the victims were found in their beds with gunshot wounds. The eldest sibling Ronald DeFeo was 23 at the time.
Amityville, a small village on the South Shore of Long Island, has enabled dozens of books and films, including “The Amityville Horror,” which was published in 1977. This was later turned into a movie in 1979 with the same name and inspired multiple remakes.
The Lutzes moved into the house shortly after the 1974 murders, so they involved not only those murders but also the Lutzes.
During two months of stay, the five-member family claimed poltergeists haunted the house who slammed windows and banged walls as well as ripped doors off their hinges.
Ronald was born on Sept. 26, 1951. His family was considered religious and well-to-do, according to a 1974 report in The New York Times.
Ronald’s family lived for nine years in a three-story house on Ocean Avenue not far from South Oyster Bay. A swimming pool was featured in the backyard, while a statue of St. Joseph holding a baby Jesus was seen on the front lawn.
Ronald’s father worked for a large car dealership named Brigante‐Karl Buick in Coney Island, Brooklyn. He also worked along with his father. They appeared to have a strained relationship.
In The Times report shortly after the killings, Amityville residents alleged that Ronald was famous for taking drugs, drinking, and fighting.
A witness said that Mr. DeFeo went to a bar near his home on Nov. 13, 1974, and announced: “that their parents had been shot.” Additionally, he reported the deaths to the police.
Later, Ronald confessed to the killings. In 1975 he went on trial for seven weeks for the murder of his relatives. An insanity defense was mounted by his court-appointed defense lawyer.
In November 1975, Ronald had been convicted of six counts of second-degree murder and sentenced to 25 years to life in prison.
