Case overview
Between July 1976 and July 1977, a gunman killed six people and wounded seven others across New York City in a series of late-night attacks that targeted young women and couples in parked cars. The investigation linked the shootings through ballistics evidence and witness descriptions, leading to the arrest of David Berkowitz, a postal worker who confessed to all eight attacks and claimed he was commanded to kill by a neighbor’s demon-possessed dog.
The first attacks and early patterns
On July 29, 1976, Donna Lauria, 18, was killed and her friend Jody Valenti wounded as they sat in a parked car outside Lauria’s apartment building in the Pelham Bay section of the Bronx. The shooter approached the passenger side and fired five shots from a .44-caliber handgun through the window. Investigators initially treated the case as an isolated incident.
On October 23, 1976, Carl Denaro and Rosemary Keenan were sitting in a parked car in Flushing, Queens, when a gunman fired through the rear window. Denaro sustained a serious head injury but survived. Police did not connect the attack to the Lauria homicide, as the victims and locations appeared unrelated.
On November 26, 1976, Donna DeMasi and Joanne Lomino were shot while sitting on the front steps of Lomino’s home in Bellerose, Queens. Both survived, though Lomino was paralyzed. Witnesses described a man who approached them asking for directions before pulling a gun. Investigators began noting similarities in victim profiles and the use of a .44-caliber weapon.
Ballistics linkage and the .44-caliber killer
On January 30, 1977, Christine Freund was killed and her fiancé John Diel wounded while sitting in a car in Forest Hills, Queens. Ballistics testing confirmed that the same gun used in the Lauria shooting had been used again. The NYPD formed a task force and began referring to the unknown suspect as the .44-caliber killer.
On March 8, 1977, Virginia Voskerichian, a 19-year-old college student, was shot and killed while walking near her home in Forest Hills. A witness reported seeing a man flee the scene. Ballistics matched the weapon to the previous attacks, and the case gained significant media attention as investigators acknowledged they were dealing with a serial killer.
The frequency and geographic spread of the attacks created widespread fear across the city’s outer boroughs. Police increased patrols in areas where young couples were known to park, and many residents altered their routines to avoid being out late at night.
The Suriani and Esau murders and the first letter
On April 17, 1977, Valentina Suriani and Alexander Esau were killed while sitting in a parked car near the Hutchinson River Parkway in the Bronx. At the scene, investigators found a handwritten letter addressed to NYPD Captain Joseph Borrelli. The letter was signed “Son of Sam” and contained rambling language in which the writer claimed to be commanded to kill and taunted police for their inability to catch him.
The letter was not immediately released to the public, but details leaked to the press. On June 1, 1977, newspaper columnist Jimmy Breslin received a letter believed to be from the same author. The letter referenced the Suriani and Esau killings and included statements about future attacks.
The NYPD released portions of the letters and urged the public to come forward with any information. Handwriting analysts and psychological profilers were brought in to assist the investigation, but no clear suspects emerged.
The Moskowitz and Violante attack and the break in the case
On July 31, 1977, Stacy Moskowitz, 20, and Robert Violante were shot while sitting in a parked car near a playground in Bath Beach, Brooklyn. Moskowitz died from her injuries, and Violante was blinded. The attack marked the first time the shooter struck in Brooklyn and the first incident in a highly populated neighborhood rather than a secluded area.
A witness reported seeing a man remove a parking ticket from a vehicle near the crime scene shortly before the shooting. Investigators obtained records of all tickets issued in the area that night and began checking the registered owners. One ticket had been issued to a Ford Galaxie registered to David Berkowitz, who lived in Yonkers.
Police conducted surveillance on Berkowitz and observed a .44-caliber rifle in the back seat of his vehicle. On August 10, 1977, officers arrested Berkowitz outside his apartment building. He immediately confessed to being the Son of Sam and admitted to all eight shootings.
Berkowitz’s statements and the investigation’s close
During interrogation, Berkowitz provided detailed descriptions of each attack that matched evidence collected by investigators. He claimed that his neighbor, Sam Carr, owned a dog possessed by a demon that commanded him to kill. He said the dog’s demands became impossible to resist and that he targeted young women with long dark hair because they fit the demon’s specifications.
Psychiatric evaluations were conducted to determine Berkowitz’s competency to stand trial. While his statements appeared delusional, experts concluded that he understood the nature of his actions and the legal consequences. In June 1978, Berkowitz pleaded guilty to six counts of second-degree murder and was sentenced to six consecutive life sentences.
In later interviews, Berkowitz recanted his claims about demonic commands and stated that he fabricated the story to support an insanity defense. He acknowledged that his motive was rooted in anger and resentment, particularly toward women, though he offered no consistent explanation for why he chose his specific victims.
Investigative limitations and unresolved questions
The case highlighted both successes and failures in the NYPD’s investigative approach. Ballistics evidence successfully linked the shootings, and the parking ticket proved critical in identifying Berkowitz. However, investigators were criticized for not connecting earlier attacks more quickly and for delays in forming a dedicated task force.
Some witnesses reported seeing more than one person near certain crime scenes, leading to speculation that Berkowitz may have had accomplices. Berkowitz himself made inconsistent statements over the years, at times suggesting others were involved and at other times retracting those claims. No evidence has conclusively supported the theory of additional shooters, and no other individuals have been charged in connection with the attacks.
The Son of Sam case also led to changes in New York law. In 1977, the state passed legislation known as the Son of Sam law, which prevented criminals from profiting from the sale of their stories. The law was later struck down by the U.S. Supreme Court as unconstitutional, but modified versions have been adopted in other states.
