Ronald Joseph DeFeo Jr., born on September 26, 1951, in the United States, is infamously known for committing one of the most shocking mass murders in American history. In 1974, he was convicted for the brutal killings of six members of his own family, including his father, mother, two brothers, and two sisters, in their home located in Amityville, New York.
DeFeo's heinous acts led to his trial, where he was found guilty of six counts of second-degree murder. The court sentenced him to a term of twenty-five years to life in prison, marking the beginning of a life behind bars for the convicted killer.
The tragic events surrounding the DeFeo family would later inspire the creation of the book and film adaptations of The Amityville Horror, which captured the public's imagination and brought further attention to the case. Ronald DeFeo Jr. passed away on March 12, 2021, leaving behind a legacy intertwined with crime and horror.
