The Judges
The Mariposa Superior Court website has no judges or judicial-assignments page. The two judges and their roles were taken from the court's own letterhead on its August 5, 2026 public notice of annual budget allocation. The roles reversed during 2026: the court's October 2025 public notice (https://www.mariposa.courts.ca.gov/system/files/general/public-notice-2025-2026-pursuant-gc685117.pdf) shows Fagalde as Presiding Judge and Starchman Bryant as Assistant Presiding Judge. The court publishes 2026 bail schedules at https://www.mariposa.courts.ca.gov/system/files/local-rules/bail-schedules-2026.pdf.

Notes on the record
- Fees: Mariposa is the only county in this group that publishes rates. The Correctional Communication System page lists NCIC calling rates per minute — local $0.07, in-state $0.07, out-of-state $0.21, Mexico/Canada $0.25, international $0.35, with no connection fees — and the Video Visitation page (https://www.mariposacounty.gov/2487/Video-Visitation) lists video visits at $0.30 per minute, messages $0.25 and picture messages $0.35.
- Commissary: https://www.mariposacounty.gov/2339/Commissary describes weekly ordering and states a person is indigent with under $2 in their account, but publishes no item prices.
- PREA: the county publishes yearly PREA statistics for 2014 through 2025 at https://www.mariposacounty.gov/1765/PREA-Reporting. These are incident statistics, not an audit result, so the audit check is recorded as no.
- Roster: the county publishes a Daily Booking Report covering the last 24 hours (https://www.mariposacounty.gov/2757/Daily-Booking-Report) under Government Code 7923.610, not a list of who is in custody now.
- Budget: the county budget page publishes recommended and adopted budgets back to 2014, including the FY 2025-2026 Adopted Budget Book and the FY27 Recommended Budget.
- Five-member Board of Supervisors, elected by district.
What California law requires
Mariposa County posts a death-in-custody page.
Posts 0 of 7The page is here. The page exists and states: 'The following deaths occurred at the Mariposa County Adult Detention Facility for which the Mariposa County Sheriff's Office has custodial responsibility. The circumstances of all unexpected in-custody deaths are investigated by an outside agency and reviewed by the Mariposa County District Attorney's Office.' A year selector offers only 2023. The 2023 report (https://www.mariposacounty.gov/DocumentCenter/View/93941/2023-Deaths) is a one-page table headed Date, Race, Gender, Age, Manner & Means of Death, Location within Facility, Custodial Status — the statutory columns — with the single entry 'Nothing to Report'. No death is therefore published and elements_present is empty. The page does not cite AB 2761 or Penal Code 10008. California DOJ Death in Custody data record one Mariposa death with county custodial responsibility since 2023: 2023-09-09, at a crime/arrest scene, custody status 'process of arrest', manner recorded as justified homicide by law enforcement staff — a death outside the detention facility, which this page's scope does not cover.
- —The agency with custodial responsibility
- —The county where the death occurred
- —The facility — and where inside it
- —Race, gender and age
- —The date of death
- —Custodial status — awaiting arraignment, awaiting trial, or incarcerated
- —Manner and means of death
California Penal Code § 10008, enacted by AB 2761 and in force since January 2023, requires the agency with custodial responsibility to post these seven items on its own website within ten days of a death in custody, and to update them within thirty days if the facts change. California is the only state in the country with this duty. Checked 2026-08-23. This records what is published, nothing more.
The record
1 people have died in the Mariposa County jail since 2021.
Deaths: Texas Justice Initiative, the cleaned copy of the Texas Attorney General’s custodial death reports — the state’s own public index carries no cause of death and has not been refreshed since August 2025. Population: Texas Commission on Jail Standards monthly report. Counted, not estimated.
These three offices decide who sits in a cell in Mariposa County and what it costs the people who live here. Nationally, almost 77% of the people who died in local jails in 2019 had not been convicted of anything, and suicide was the leading single cause of those deaths (Bureau of Justice Statistics, Mortality in Local Jails, 2000–2019).
