Vallejo police chief issues intended termination letter to officer who killed Sean Monterrosa

VALLEJO, Calif. (KGO) -- The ABC7 News I-TEAM has obtained a copy of Vallejo Police Chief Shawny Williams' intended discipline - termination letter to the officer who shot and killed Sean Monterrosa June 2, 2020.

The letter is dated December 1, 2021. The officer's name is redacted. However, a lawsuit filed by the Monterrosa family previously named the officer as Jarrett Tonn.

In the letter, Chief Williams writes, "I am notifying you of my intent to terminate your employment with the Vallejo Police Department. If my intention remains unchanged following completion of any pre-disciplinary review in this matter, then I will notify you in writing of your termination following completion of this pre-disciplinary process."

The letter outlines five policies and procedures Chief Williams says the officer violated, including de-escalation.

Last week, the Vallejo Police Department released the findings of a nearly year-long independent administrative investigation into a the officer's fatal shooting of Monterrosa. The officer shot and killed Monterrosa from the back seat of an unmarked police vehicle outside a Walgreens looting.

In its 66-page report, an independent police oversight and review group found the officer's use of force was not objectively reasonable when he shot and killed Monterrosa through the windshield from the backseat of unmarked police vehicle.

California Attorney General Rob Bonta announced Thursday that the California Department of Justice will conduct an independent review of the police shooting death of Sean Monterrosa to determine whether criminal charges are warranted.



Monterrosa was outside a Walgreens June 2 last year where there had been a looting during a protest over George Floyd's murder by police. Vallejo police said Monterrosa was crouched down in a half kneeling position, moving his hands towards his waist area revealing what appeared to the officer to be the butt of a handgun.

It turned out to be a hammer. The report found Monterrosa's action was potentially consistent with an intent to surrender. The report also revealed the fatal shot entered the back of Monterrosa's head, inconsistent with officers' statements that he was facing them in an aggressive shooting stance at the time.

While officers are not expected to be absolutely sure of a threat before using deadly force according to the report, the second guessing by the officer who shot and killed Monterrosa suggested significant uncertainty about whether Monterrosa was carrying a gun. That uncertainty was captured by the officers' body worn cameras.
