On this day in 1974, Ronald DeFeo, Jr. murdered his entire family in Amityville, Long Island, the United States of America, in the house that would become known as The Amityville Horror.
He was tried and convicted for the killings of his father, mother, two brothers, and two sisters.
The case inspired the book and film versions of The Amityville Horror.
The victims were his parents: Ronald DeFeo Sr. (44) and Louise DeFeo (42); and his four siblings: Dawn (18), Allison (13), Marc (12), and John Matthew.
All of the victims had been shot with a .35 caliber lever action rifle around three o’clock in the morning of that day.
The deceased were later buried in nearby Saint Charles Cemetery in Farmingdale.
On November 21, 1975, DeFeo was found guilty on six counts of second-degree murder.
On December 4, 1975, he was sentenced to six concurrent sentences of 25 years to life.
All of his appeals for parole have been denied.
