New York City in the 1970s was already a city on edge—soaring crime rates, blackouts, financial crisis, and social unrest. Into this atmosphere stepped David Berkowitz, a postal worker turned serial killer who would terrorize the city for more than a year. Known infamously as the “Son of Sam,” Berkowitz left six people dead, seven wounded, and a city living in fear. His story is one of adoption, isolation, delusion, and obsession—making him one of America’s most notorious serial killers.
This in-depth blog will explore Berkowitz’s early life, the evolution of his crimes, the psychological profile behind his killings, the police investigation, arrest, trial, and the long shadow he still casts over true-crime culture.
Early Life of David Berkowitz: From Adoption to Alienation
David Richard Berkowitz was born June 1, 1953 in Brooklyn as Richard David Falco to a single mother, Elizabeth Broder. Elizabeth had an affair with a married man, Joseph Kleinman, who pressured her to give up the baby. At a few days old, he was adopted by Nathan and Pearl Berkowitz, a middle-class Jewish couple from the Bronx. They renamed him David Richard Berkowitz.
- Childhood Struggles:
Berkowitz was described as bright but troubled. Teachers and neighbors noted his tendency to isolate himself. He had mood swings, a fascination with petty theft, and a pattern of setting fires—a classic indicator in criminal psychology known as part of the “Macdonald Triad” (fire-setting, cruelty to animals, and bedwetting). - Loss of Adoptive Mother:
Pearl Berkowitz died of breast cancer when David was only 14. This loss deepened his feelings of abandonment and resentment. He later discovered his birth mother’s identity and illegitimacy, which fueled feelings of rejection. - Military Service:
In 1971, he enlisted in the U.S. Army, serving at Fort Knox and later in South Korea as a marksman—a skill that would tragically resurface later. He left the Army in 1974 with an honorable discharge but no direction or support system.
The Descent into Darkness: Arson and Occult Fixations
Back in New York, Berkowitz worked for the U.S. Postal Service as a letter sorter. But at night, he fed darker impulses. He claimed to have set over 1,400 fires throughout the city, meticulously recording them in notebooks found later by police.
- Occult Involvement:
In interviews, Berkowitz spoke of being drawn to Satanic cults in Yonkers. Some investigators and journalists believe he was part of a larger occult network, though this has never been proven. He also began hearing “voices” from his neighbor’s black Labrador, allegedly transmitting orders from a demon named Sam. - Delusions and Rituals:
Berkowitz believed he was a soldier in a supernatural war, compelled to kill to appease dark forces. These delusions became the twisted foundation for the “Son of Sam” persona.
The Timeline of the “Son of Sam” Murders (1976–1977)
Berkowitz began his killing spree in July 1976, targeting mostly young women and couples sitting in parked cars. His choice of victims and weapon gave him another moniker: “The .44 Caliber Killer.”

The “Son of Sam” Letters – Taunting the Public
Berkowitz fed the hysteria by writing bizarre, mocking letters to the police and press under the name “Son of Sam.”
- First Letter: Left at the April 1977 crime scene, it warned police that “I am a monster. I am the Son of Sam.”
- Direct to Media: He also wrote to newspaper columnist Jimmy Breslin of the New York Daily News, which published excerpts. These letters described his demonic mission and promised more killings.
- Result: Instead of throwing police off, the letters escalated public fear and made him a macabre celebrity.
The Largest Manhunt in NYC History
By mid-1977, the NYPD had assigned over 300 officers to the case under Operation Omega. Detectives pored over thousands of tips, ballistics reports, and psychological profiles.
- Profile: FBI experts described the killer as a lone white male in his mid-20s to early 30s, living alone, socially isolated, and possibly with military experience—a chillingly accurate description.
- Clue Breakthrough: A parking ticket issued near the final shooting scene to a cream-colored Ford Galaxie led to Berkowitz’s Yonkers address.
- Witness Accounts: Residents reported strange behavior, including Berkowitz shooting arrows in the street and threatening notes left on neighbors’ doors.
Arrest of David Berkowitz
On August 10, 1977, police surrounded Berkowitz’s apartment. When they opened his car, they found maps of crime scenes, a .44 caliber revolver, and a letter promising more violence. Inside his apartment were occult books, Satanic graffiti, and diaries cataloging over a thousand arsons.
When arrested, Berkowitz reportedly smiled and said:
“Well, you got me. How come it took you so long?”
Trial, Sentencing, and Prison Life
Initially, Berkowitz pleaded not guilty by reason of insanity. After psychiatric evaluation found him competent, he changed his plea to guilty for all six murders and received six consecutive life sentences without parole.
- Prison Transformation: In the late 1980s, Berkowitz claimed to have become a born-again Christian, calling himself the “Son of Hope” instead of “Son of Sam.”
- Parole Hearings: He has been denied parole multiple times and has publicly stated he no longer seeks release.
- Current Status: As of today, Berkowitz remains incarcerated in a New York state prison, writing religious essays and letters to crime researchers.

Experts still debate Berkowitz’s mental state:
- Paranoid Schizophrenia vs. Psychopathy: He exhibited delusions but also calculated his attacks.
- Cult Theory: Some investigators, notably journalist Maury Terry in The Ultimate Evil, argued Berkowitz was part of a Satanic cult orchestrating murders. Berkowitz has hinted at this in interviews but never confirmed it fully.
- Need for Recognition: His letters and theatrics show a craving for attention—classic narcissistic traits common in serial killers.
