San Francisco deputy faces arraignment in jail assault case tied to class action

A San Francisco Sheriff’s Office deputy is set to be arraigned July 14, 2026, on battery and assault-by-a-public-officer charges stemming from conduct at County Jail No. 2. The criminal case intersects with a federal civil rights class action alleging a broader pattern of degrading searches and retaliation against women in custody.

Why it matters: - The criminal case adds legal pressure to San Francisco’s jail operations while a separate federal class action accuses the Sheriff’s Office of systemic abuse at the same facility. - The charges could strengthen claims by women who say they were mistreated inside County Jail No. 2 and then punished for speaking out. - The arraignment centers attention on whether the conduct was an isolated assault or part of a broader pattern of misconduct.

What happened: - San Francisco Sheriff’s Office Deputy Nanette Musto, 51, is scheduled to be arraigned this morning on charges of battery and assault by a public officer. - The arraignment is set for 9:00 a.m. in Department 17 at the Hall of Justice, 850 Bryant Street, San Francisco, under Court Number 26016092. - District Attorney Brooke Jenkins announced the charges on July 13, 2026. - The alleged incident happened on July 12, 2025, while Musto was on duty at County Jail No. 2. - The District Attorney says Musto asked a female inmate whether she had surgically augmented her body and then touched the inmate’s breast without permission or lawful necessity. - The alleged encounter was captured on jail surveillance footage. - The woman reported feeling humiliated and embarrassed. - Musto is charged under California Penal Code section 242 and one misdemeanor count under Penal Code section 149.

The details: - The complaining witness in the criminal case is a plaintiff in the civil lawsuit filed by The Veen Firm and Bertolino Law. - The civil complaint was filed May 22, 2026, in the U.S. District Court for the Northern District of California. - The lawsuit is Sahagun Lopez, et al. v. City and County of San Francisco, et al. - The suit is brought on behalf of 20 women. - The complaint alleges a supervisor-authorized pattern of degrading, suspicionless searches at County Jail No. 2. - The complaint says a May 22, 2025 mass strip search involved male deputies watching women undress while body-worn cameras recorded. - The lawsuit says the searches violated the Sheriff’s own policy. - The complaint also alleges denial of menstrual hygiene and retaliation against women who complained.

Between the lines: - The case highlights how a criminal prosecution can intersect with civil rights litigation when one alleged incident becomes evidence in a broader institutional challenge. - The timing is also notable: the charges came about a year after the alleged conduct and after the women sued. - Plaintiffs’ lawyers are using the criminal case to argue the allegations were credible from the start and that the City and County still must answer for the broader claims. - Elizabeth Bertolino said the charges confirm what the client had been saying and called the development “vindication.” - Anthony Label said the case shows the conduct happened inside a jail that broke its own rules and then punished women who spoke up.

What’s next: - Musto’s arraignment will move the criminal case forward in San Francisco Superior Court. - The civil class action is still pending in federal court. - Counsel said interviews are available around the arraignment, and the plaintiff who reported the incident is available for comment through counsel. - The next legal focus will likely be how the criminal charges affect discovery, witness credibility and settlement pressure in the civil case.

The bottom line: - A single deputy’s arraignment has become a flashpoint in a wider fight over how women were treated inside San Francisco’s jail system.
