Between the summers of 1976 and 1977, David Berkowitz, a.k.a. “Son of Sam,” terrorized New York as he gunned down innocent young people in their cars. He claimed that Satan had possessed his neighbor Sam’s dog which then sent him messages to kill.

The story would give Berkowitz his monicker and help to cement his place in serial killer history, but he later admitted that it was all a hoax.

Likewise, he was never diagnosed with any mental disorders and, after several examinations, was found mentally competent to stand trial by the state.

So, as for who to blame for the Son of Sam’s six killings, in David Berkowitz’s own words, “It was just me, myself and I.”

Who Was David Berkowitz?

Richard David Falco, later to be known as David Berkowitz, was born in Brooklyn, New York in 1953. His parents were unwed and after separating shortly after Berkowitz’s birth, put him up for adoption. He was taken in by the Berkowitz coupled and so renamed.

Even as a child it was obvious to those around Berkowitz that he had violent tendencies. He was caught thieving, destroying property, killing animals, and setting fires. As he grew older, Berkowitz also lamented his lack of social life and his inability to get a girlfriend.

“Sex, I believe, is the answer – the way to happiness,” he said once. This key to happiness is what he felt he was being denied.

At 14, his adoptive mother died and his adoptive father remarried. Tensions in the family grew strained. So in 1971, at 18, Berkowitz enlisted.

In 1974, two years before the Son of Sam killings began, David Berkowitz returned from a three-year military stint in South Korea.

The 21-year-old moved into a small apartment in Yonkers, New York and found that all his former friends and acquaintances had moved on. Alone and still dealing with those emotions relating to his adoption and the death of his adoptive mother, Berkowitz grew despondent, lonely — and, most of all, angry.

The following year, at age 22, Berkowitz found out that his birth mother, Betty Falco, who he’d believed had died in childbirth, was still alive. However, upon meeting her, she seemed somewhat distant and disinterested. This supplemented a growing belief in Berkowitz that he was unwanted not just by his own mother, but by all women.

Finally, by Christmas Eve 1975, something inside David Berkowitz had snapped.

He followed two teenage girls on the street and stabbed them from behind with a hunting knife. Both survived, but neither could identify their attacker. Unfortunately, this violent outburst was only the beginning.

On July 29, 1976, after acquiring a .44 caliber gun in Texas, Berkowitz approached a parked car from behind in a Bronx neighborhood. Inside, Jody Valenti and Donna Lauria were talking.

Berkowitz fired several shots into the car, killing Lauria and wounding Valenti. He then left without looking inside the car, only finding out in the newspaper the next day that he just killed his first victim.

After getting away with his first murder, Berkowitz went on a killing spree that lasted for 12 months. By the time he completed his eighth and final attack in July 1977, he had killed six people and wounded seven, almost all of them young couples sitting in their cars at night.

Since his sixth attack in April 1977, Berkowitz had been writing taunting letters to the New York Police Department, and then also to Daily News columnist Jimmy Breslin. It was in these letters that “Son of Sam,” and the citywide fear of him, was born. Up to this point, Berkowitz had been dubbed “The .44 Caliber Killer.”

“To stop me you must kill me,” wrote Berkowitz in one of the letters. “Sam’s a thirsty lad and he won’t let me stop killing until he gets his fill of blood,” he added.

By the end of the Son of Sam killing spree, New York had gone into a kind of panicked lockdown. As almost all of the female victims had dark hair, women across New York City began to dye their hair or buy wigs and the subsequent search for the so-called Son Of Sam was the largest manhunt in New York history at the time.

The end of the killings came on July 31, 1977, when Berkowitz killed Stacy Moskowitz and seriously blinded her companion, Robert Violante, in the Bath Beach neighborhood of Brooklyn.

The Capture And Incarceration Of The Son Of Sam

After Moskowitz’s murder, police received a call from a witness who would break the Son of Sam case wide open. This witness saw a suspicious-looking man near the scene holding a “dark object” and taking a $35 parking ticket from his car window.

Police searched the area ticket records for the day and pulled up the license plate number of 24-year-old postal worker David Berkowitz.

Thinking, at the very least, that they had found another witness to the crime, police arrived outside Berkowitz’s Yonkers apartment and saw his car. Inside was a rifle and a duffel bag filled with ammunition, maps of the crime scenes, and another letter meant for the authorities.

Upon Berkowitz’s exit from the apartment, arresting officer Detective Falotico held a gun to him and said, “Now that I’ve got you, who have I got?”

“You know,” Berkowitz said in what the detective remembered was a soft, almost sweet voice. “No, I don’t.” Falotico insisted, “You tell me.” The man turned his head and said, “I’m Sam.”

Berkowitz reportedly also taunted the arresting officers, asking them what took them so long to find him. Once in custody, Berkowitz informed the police that a man from 6,000 years ago named Sam spoke to him through his neighbor Sam Carr’s black Labrador Retriever, commanding him to kill.

When police search Berkowitz’s apartment they found Satanic graffiti scrawled on the walls and diaries with details of his cruel activities, including all the fires he had set since he was 21.

After three separate mental aptitude tests, it was determined that the Son of Sam was certainly fit to stand trial. With copious evidence stacked against him and attempts to use an insanity defense thwarted by psychiatric testing, Berkowitz pled guilty to all charges.

He was given six 25-years-to-life sentences at Shawangunk Correctional Facility in Wallkill, New York.

His adoptive father, David Berkowitz Sr., sobbed for the victims of his son’s violence in a public press conference offering his condolences and apologies. When asked what the younger Berkowitz was like as a child, Berkowitz Sr. could not reply.

David Berkowitz would admit about three years later that he never truly believed that he’d been possessed by his neighbor’s dog.

The Son of Sam killings of David Berkowitz were the subject in season two of Netflix’s Mindhunter crime series. He was portrayed by the actor Oliver Cooper and the actor opposite him, Holt McCallany, who plays the detective, actually tried to have an interview with the real David Berkowitz.

In 2011, Berkowitz stated he had no interest in pursuing parole.

Today, David Berkowitz is a born-again Christian with an official website, run by his supporters, that claims that this “former Son of Sam” is now “the son of hope.”
