The family of Sean Monterrosa, the 22-year-old who was fatally shot by Vallejo police on June 2, filed a civil lawsuit today against the City of Vallejo, the Vallejo Police Department, and Vallejo Police Officer Jarrett Tonn, who allegedly shot Monterrosa. 

In the lawsuit filed in federal court, the family seeks “damages for violation of civil rights and wrongful death,” as well as a jury trial. 

“There is no comfort for Mr. MONTERROSA, for his parents, and for his two sisters,” the lawsuit states. “They have not been through this before and will never be alright again, because Defendant TONN was trigger-happy, could not see accurately through the unmarked police car windshield, and murdered their son and brother, who was only 22 years old.”

Monterrosa’s parents, Neftali and Nora Monterrosa, and his sisters Michelle and Ashley, stood with their attorney, John Burris, and tens of others in front of the Vallejo City Hall to publicly announce the suit. 

“We just want justice for everyone,” Neftali Monterrosa said.

Tonn shot five rounds at Monterrosa through the windshield of an unmarked pickup truck after he and other officers mistook a hammer in Monterrosa’s pocket for a gun, Vallejo Police Chief Shawny Williams said in a video released by the department July 8. 

In the video, Williams said Monterrosa appeared to be crouching in preparation to shoot. The lawsuit acknowledges how Williams’ initial statements about the incident describes Monterrosa as kneeling with his hands up. 

Although two other officers were in the unmarked truck, the family sued Vallejo police officer Tonn because multiple outlets named him as the officer who shot Monterrosa through the windshield. Tonn, two other detectives and one captain responded to reports of looting at a Walgreens that night.  

At the press conference, the lawyers said that Tonn had a history of shooting that should have prohibited him from even being on the scene. The lawsuit specifically said that Tonn had committed three prior shootings and was “never disciplined and never subject to re-training or remediation.”

“Is this a moment or a movement?” Burris said to the crowd in front of Vallejo City Hall. “This is an opportunity to evaluate the practices that have taken place in the city. Let’s hold officers accountable.”

The lawsuit also faults the city, which is in charge of the police department, for allowing a police department employee to get rid of key evidence. The windshield Tonn shot through was destroyed, and the pickup truck was put back into service despite the ongoing investigation. 

California Attorney General Xavier Becerra said he will investigate the destruction of evidence, though he had declined to look into Monterrosa’s case after Solano County District Attorney Krishna Abrams’ asked Becerra to take over. Abrams recused her office from the case early on, citing the community’s lack of trust in her office. Becerra responded, stating that without a conflict of interest, this personal investigation was not in the state’s jurisdiction.  

Nora Monterrosa told the crowd at Vallejo City Hall that she wanted Becerra to investigate her son’s case. 

“Stand up, Xavier Becerra!” She said in Spanish.

Tens of people came to the press conference in support of the Monterrosa family and listened eagerly as Burris explained the lawsuit’s implications. He used a blown-up image from one of the officer’s body cameras as a visual. Some supporters donned shirts with an image of a toucan, a reverent nickname for Sean

Erick Gutierrez, an El Sobrante resident, said he came after learning about the event online. 

“Other families who have been in this position have not gotten the justice for their loved ones,” Gutierrez said. “Vallejo has been particularly bad.”

Additionally, earlier this morning, Michelle and Ashley Monterrosa voiced support for a reinvigorated California Assembly bill that seeks to compensate victims of police violence and their families, and that will be heard at a Senate committee tomorrow. 

At the assembly bill’s online press conference, which was joined by several people, including San Francisco District Attorney Chesea Boudin and California Assemblyman David Chiu, Michelle Monterrosa tearfully recounted her and her sister’s taxing experiences advocating for their brother’s justice for two months.  

“No one should have to fight for justice and carry on the pain with no resources and support,” Michelle said at the bill’s press conference. ”No matter what the police report says, there were five victims when my brother was murdered.”

Despite the tragedy of the event, Ashley said at Vallejo City Hall that she believed this could act as a moment to draw attention to other injustices related to police brutality. 

“He brought such a light,” Ashley said of her brother. “He died a martyr and died for a greater cause.” 

Then, she addressed a message to Vallejo officers accused of exhibiting and promoting excessive use-of-force

“Your time is up. Your downfall is coming.”

  1. This is a horrible tragedy and a bloody murder execution style. He lost his life because the pharmacy and Walgreens was closed. Shawn I assumed thaught it was open 24/7. Racist cops. We need to get rid of all cops.

    1. Ricardo, getting rid of cops is just unrealistic , we live in a world where some people are not civil and are a danger to themselves or the public. You have places like Chicago that need good cops because of the black on black genocide that continues to go on in places like this and other parts of the country in which black and brown gun and murder each other down. What you want is just not in sync with the reality we are facing. Sean was trying to loot with his friends, and they were never truly his friend, his friends abandoned him once he was caught and gunned down by the cops. During this time, a curfew was set because of all the civil unrest of protesting and looting and police going all out over the chaos that unfolded. Why in Gods name wasn’t he at home, it wasn’t safe outside to begin with. A person with common sense would not be out there with all the vandalism and violence and police activity going on. Its no joke being out there and participating in these kinds of behavior, there is danger all around. Racism has nothing to do with it, He made a choice that cost him his life, and caused his family to grieve. All around its sad because had he been with his parents that night instead of his fake friends then he would still be alive. Wisdom is a gift from the heavens and we should never take it for granted

    2. Yes, but was the hammer in his waistband his co-pay for his prescription? C’mon.

      No one deserves to die for attempted robbery of a drugstore, and certainly not without due process –but if you don’t do illegal things then you don’t have to encounter the police at all.

      At least admit that he shouldn’t have been doing illegal things, late at night with a weapon. Then we can both agree that he shouldn’t have died at the hands of angsty police.

      While you can ignore the facts, you can’t diminish the truth. RIP.

  2. BLM!

    Sean should not have been executed for alleged attempted looting.

    I do greatly resent him going 40 miles out of his way to come sh!t on my town.

    We have enough folks locally to protest and make our grievances known we don’t need help from South San Francisco.
