Ten men have been indicted in connection with a September 2025 brawl at Redwood City's Maguire Correctional Facility, county prosecutors said. The fight involved an estimated 30 incarcerated people, left four sheriff's deputies with minor injuries and sent six inmates to local hospitals. The defendants now face a slate of charges that include assault on custodial officers, assault causing great bodily injury and alleged weapons possession inside the jail.
Chief Deputy District Attorney Shin-Mee Chang told reporters the office is arraigning the defendants on a grand-jury indictment and has grouped them by their alleged roles in the melee. According to the San Mateo Daily Journal, the first group, Kenneth Arvizu, Jose Amador, Tevita Taunaholo, Marvin Ware and Phillip Nimro Wilson Jr., is charged with assault on custodial officers, battery and resisting an executive officer. A second group, Joshua Thomas, Jylyn Richardsongreen, Eddie Burns Jr., Mosese Taunaholo, and Malaki Luliolaoa, faces counts that include assault causing great bodily injury, resisting an executive officer, and having a weapon while in custody.
What happened in September
The brawl broke out around 10:45 AM during recreation time in a housing unit, according to deputies, and officers used gas and other less-lethal measures to regain control. Authorities estimate that about 30 inmates were involved. Six were taken to area hospitals for treatment, and four deputies suffered minor injuries, as reported by KTVU.
Staffing and safety concerns
In the weeks leading up to the melee, the Organization of Sheriff's Sergeants had warned that changes to overtime and staffing practices were leaving shifts short, and local coverage has tied those complaints to broader safety concerns at county jails. Sheriff Christina Corpus, however, publicly praised corrections staff for their response, saying their quick action "undoubtedly prevented more serious injuries," according to the San Francisco Chronicle.
Legal next steps
The district attorney's office said arraignments on the grand-jury indictment are underway and that prosecutors may amend charges as the case moves through the courts. Court dates and detailed docket filings were not immediately available. Those records are expected to be viewable through the county clerk and the district attorney's office, the San Mateo Daily Journal reports.
