The Monterey County District Attorney’s Office released preliminary information and body camera footage this week detailing a fatal police shooting in Marina lastSunday, stating that the man killed by officers was armed with a loaded handgun.
In a summary released Thursday, prosecutors said the findings are based on video evidence, interviews with officers involved in the incident, and court records.
The man who died was identified as Ronald Tinsley.

According to the District Attorney’s Office, the incident began at approximately 4:50 p.m. when Marina Police Officer Shivdev Dhillon observed a van traveling without a front license plate.
Dhillon recognized the driver as Tinsley, whom he had previously arrested in June 2025 on suspicion of being a felon in possession of ammunition.
Prosecutors said Tinsley was also believed to be affiliated with a gang.
The officer was aware that Tinsley had been charged in December in a felony domestic violence case and had injured officers while resisting arrest in that earlier incident, according to prosecutors.

Both the ammunition and domestic violence cases were still proceeding through the court system at the time of the shooting, and prosecutors said Tinsley had posted bail in both matters.
After turning his patrol vehicle around, Dhillon also observed that the van’s registration was expired, prompting him to initiate a traffic stop.
During the stop, prosecutors said Dhillon noticed Tinsley using his phone and believed he saw the name of the alleged victim in the domestic violence case displayed on the screen.
Dhillon asked to see the phone, believing that a court order prohibited Tinsley from contacting the woman involved in the case.
According to the summary, Tinsley refused to show the phone and told the officer he was speaking with his mother.
As the stop continued, Officers Brodie Sievers and Gabriel Rose arrived on the scene to assist, citing Tinsley’s criminal history.
The two officers exited their patrol vehicles and positioned themselves on opposite sides of the van.
Prosecutors said Dhillon instructed Tinsley to step out of the vehicle, citing concerns that Tinsley might be armed and describing behavior he considered suspicious.
Tinsley did not comply with the commands.
When Dhillon attempted to turn off the vehicle’s ignition, prosecutors said Tinsley pressed the accelerator.
A struggle followed, during which both Dhillon and Tinsley fought for control of the steering wheel.
Prosecutors said Tinsley repeatedly struck Dhillon in the head during the struggle.
The van ultimately came to rest in a small embankment approximately 300 feet from the initial traffic stop.
After the vehicle stopped, Dhillon observed Tinsley reaching for an object wrapped in cloth near his leg, prompting another struggle.
According to the District Attorney’s Office, Tinsley attempted to raise the object, which Dhillon believed was a revolver.
Sievers ran toward the vehicle after hearing Dhillon shout that Tinsley had a gun.
Prosecutors said Sievers observed the firearm in Tinsley’s hand through the passenger-side window, partially covered by Dhillon’s hand.
The gun was pointed in Sievers’ direction.
Fearing for their lives, prosecutors said both Dhillon and Sievers each fired one round from their service weapons.
One of the rounds struck Tinsley.
Body camera footage showed Dhillon handing Tinsley’s revolver to Sievers after the shooting.
An examination later determined that the firearm was loaded.
Following the shooting, prosecutors said Dhillon provided medical assistance to Tinsley while other officers performed CPR.
Paramedics arrived at the scene, but Tinsley was pronounced dead.
Investigators recovered a bindle of methamphetamine from Tinsley’s pocket, though prosecutors said it was not immediately known whether the drug affected his judgment.
Toxicology results remain pending.
An autopsy determined that Tinsley died from a single gunshot wound. The bullet entered his left shoulder and traveled through his aorta, according to the report.
Ballistics testing showed that the bullet recovered from Tinsley’s body was a .40-caliber round.
Prosecutors said Dhillon fired one round from his .40-caliber semiautomatic pistol, while Sievers fired one round from his 9mm semiautomatic pistol.
Testing of Tinsley’s revolver determined that the firearm was fully operational and unregistered, prosecutors said.
According to the District Attorney’s Office, Dhillon has seven years of experience as a peace officer, while Sievers has two and a half years of experience.
Prosecutors said the investigation into the shooting remains ongoing.
