Investigation Overview
Detectives assembled a task force to analyze shooting patterns, weapon types, and survivor accounts. Early theories about cult involvement were tested and later ruled out as evidence pointed to a single gunman.
The breakthrough came when investigators noticed similarities in letters sent to newspapers, including distinctive phrasing and detailed claims about the shootings. Linguistic analysis linked the writings to the suspect’s personal profile.
Forensic and Physical Evidence
Ballistics testing connected multiple crime scenes to the same firearm, narrowing the pool of possible owners. Shell casings recovered from cars and building entrances matched the unique firing pin mark of the Bulldog revolver.
Neighbors described a suspicious man in the area shortly before and after attacks. These descriptions aligned with images of David Berkowitz, who owned a car similar to one seen fleeing one of the shooting locations.
Witnesses and Parking Ticket Details
A parking attendant reported a vehicle parked illegally near a shooting scene, writing down the license plate number. The ticket provided investigators with a tangible lead they could trace through city databases.
When the ticket was reviewed, the registration pointed toward an address associated with Berkowitz. Combined with behavioral profiling, this physical piece of evidence became central to securing a warrant.
Arrest and Confession Process
After surveillance identified Berkowitz as a person of interest, detectives obtained a search warrant for his Queens apartment. Firearms matching ballistic evidence were located during the search.
Following arrest, Berkowitz initially claimed a neighbor named "Son of Sam" had forced him to shoot. Under continued interrogation, he confessed in writing, detailing his actions and motivations, which led to formal charges and a guilty plea.
