Marina, California – A man fatally shot by Marina police officers during a traffic stop on Sunday was armed with a loaded handgun, according to newly released information from the Monterey County District Attorney’s Office. Prosecutors say body camera footage, officer interviews, and court records support the finding as the investigation into the shooting continues.
Incident Overview
The man killed in the shooting was identified as Ronald Tinsley, prosecutors said. The fatal encounter occurred during a traffic stop that escalated into a physical struggle between Tinsley and an officer, ultimately ending when officers fired their weapons after believing their lives were in immediate danger.
The Monterey County District Attorney’s Office released a preliminary summary of the incident on Thursday along with portions of body-worn camera footage.
Timeline of Events
According to prosecutors, the incident began at approximately 4:50 p.m. on Sunday when Officer Shivdev Dhillon observed a van in Marina that did not have a front license plate. Dhillon recognized the driver as Tinsley, whom he had arrested in June 2025 on suspicion of being a felon in possession of ammunition and who was believed to have gang affiliations.
Court records reviewed by prosecutors also indicated that Tinsley had been charged in December in a felony domestic violence case and had allegedly injured officers while resisting arrest in that prior incident. Both cases were still pending, and Tinsley had posted bail, according to the DA’s office.
After turning his patrol vehicle around, Dhillon noticed the van also had expired registration, prompting him to initiate a traffic stop.
Details From Prosecutors
During the stop, Dhillon reportedly saw Tinsley’s phone and believed he recognized the name of the alleged domestic violence victim displayed on the screen. Prosecutors said Dhillon believed Tinsley was prohibited by court order from contacting the woman and asked to see the phone.
Tinsley refused and told the officer he was speaking with his mother.
At that point, Officer Brodie Sievers and Officer Gabriel Rose arrived to assist, citing concerns related to Tinsley’s criminal history. The two officers positioned themselves on either side of the van.
Prosecutors said Dhillon asked Tinsley to exit the vehicle due to concerns he might be armed and because of behavior the officer considered suspicious. Tinsley did not comply.
Escalation and Use of Force
According to the DA’s summary, when Dhillon attempted to turn off the vehicle’s ignition, Tinsley hit the accelerator, resulting in a struggle over the steering wheel. Prosecutors said Tinsley repeatedly struck Dhillon in the head during the struggle.
The van eventually came to rest in a small embankment approximately 300 feet from the initial stop location.
Dhillon then observed Tinsley reaching for an object wrapped in cloth near his leg. Prosecutors said another struggle ensued as Tinsley attempted to raise the object, which Dhillon believed was a firearm.
Witness Accounts and Body Camera Evidence
Officer Sievers ran toward the van after hearing Dhillon shout that Tinsley had a gun.
“Dhillon yelled that Tinsley had a gun,” prosecutors stated in their summary.
Sievers then saw what appeared to be a firearm in Tinsley’s hand through the passenger-side window, partially covered by Dhillon’s hand. The gun was pointed in Sievers’ direction, according to prosecutors.
Fearing for their lives, both Dhillon and Sievers fired one round each. One of the shots struck Tinsley.
Body camera footage later showed Dhillon handing the revolver to Sievers after the shooting. Investigators determined the gun was loaded, fully operational, and unregistered.
