A 35-year-old woman, Jasmine Zamion, who had been booked into the Bexar County Adult Detention Center on a trespassing charge, was found dead in her cell Sunday morning. Jail medical staff and emergency responders attempted life-saving measures. Authorities have launched both internal and external investigations into her death.
According to WOAI, Zamion was arrested Friday on a criminal trespass charge and had been in the unit since Saturday. Medical personnel from University Health, who are stationed at the jail, responded and tried to revive her before San Antonio Fire and EMS pronounced her dead at about 9:00 a.m., the outlet reported.
Independent Probe Launched Under Sandra Bland Act
According to KSAT, the Castle Hills Police Department is conducting the independent investigation required by the Sandra Bland Act, and the Texas Commission on Jail Standards has been notified. The Bexar County Sheriff’s Office Internal Affairs Unit has also opened an administrative review, which is standard after any in-custody death.
What The Law Requires
The Sandra Bland Act, formally Senate Bill 1849, requires the Texas Commission on Jail Standards to appoint an outside law-enforcement agency to investigate deaths that occur in county jails. It also mandates that jails provide continuity of medical and mental health care for people held in custody. The full statutory language and provisions are available via SB1849.
Deaths This Year And Local Concern
Local media and watchdog groups have tracked several in-custody deaths at the Bexar County Adult Detention Center in 2025, a string of cases that has drawn sharp scrutiny from community members and defense attorneys. Prior coverage has marked the ninth death this year and raised recurring questions about medical care and inmate monitoring at the facility. Advocates say this latest death is likely to further increase pressure on county leaders to address staffing levels and oversight inside the jail.
What Happens Next
Investigators from the outside agency and the sheriff’s internal affairs unit are expected to collect medical records, incident reports, surveillance footage, and other evidence and submit their findings as required. County officials have not released further information beyond initial news releases.
