Sean Arthur Robinson, a 38-year-old resident of Stockton, was sentenced to two years in prison followed by three years of supervised release for being a felon in possession of a firearm. The sentence was handed down by Senior United States District Judge John A. Mendez, as announced by Acting United States Attorney Michele Beckwith.
The case stems from an incident in September 2022 when law enforcement officers executed a search warrant at Robinson's residence in Stockton. During the search, they found a Glock 27 semiautomatic firearm and a loaded high-capacity magazine inside a vehicle. The firearm had been reported stolen from Sacramento. Additionally, on the same day, officers discovered two Glock switches at another residence linked to Robinson in Fairfield. Due to prior convictions for elder abuse and carrying a loaded firearm in public, Robinson is prohibited from possessing firearms.
The investigation into Robinson began as early as May 2021 after surveillance footage captured him involved in a violent shootout at the Grand Hyatt Hotel near San Francisco International Airport. During this event, Robinson and an accomplice attempted to carjack multiple vehicles. Following the shootout, law enforcement retrieved a black duffel bag that surveillance footage showed Robinson carrying before the incident; it contained three illegal firearms.
This case resulted from an FBI investigation with assistance from the San Francisco Police Department. It was prosecuted by Assistant U.S. Attorneys Justin Lee and Sam Stefanki.
The prosecution is part of Project Safe Neighborhoods (PSN), which aims to reduce violent crime and gun violence through collaboration between law enforcement agencies and communities. The Department launched an enhanced violent crime reduction strategy on May 26, 2021, emphasizing trust-building within communities, supporting violence prevention organizations, setting strategic enforcement priorities, and measuring outcomes.
