Sean Monterrosa was 22 when he was shot and killed by Vallejo police officer Jarrett Tonn on June 2, 2020. The shooting occurred about 12:30 a.m. during a citywide curfew amid protests and looting after George Floyd’s murder. Monterrosa was on his knees with his hands above his waist when Tonn fired through the windshield of an unmarked police pickup, apparently believing a hammer in Monterrosa’s pocket was a gun. Monterrosa later died at a local hospital.

Tonn had been a Vallejo officer since 2014 and had been involved in three prior on-duty shootings that did not result in deaths; internal investigations cleared him in those incidents. The Vallejo Police Department already had a high per capita rate of police shootings in Northern California, and Monterrosa’s death joined prior controversial Vallejo police shootings including Ronnell Foster in 2018 and Willie McCoy in 2019. The California Department of Justice took over the criminal investigation in May 2021, but as of June 2023 the Attorney General’s office had not provided public updates. Key evidence complications include obscured body camera footage and destroyed drone footage, and no criminal charges against Tonn have been announced.

Does anyone have information about what happened that night or about witnesses who saw Monterrosa before he was shot?
