BEXAR COUNTY, Texas – A Bexar County jail inmate died at a local hospital following a suspected medical episode on Sunday, according to the sheriff’s office.
Casandra Monette Pearson, 29, was pronounced dead at the hospital at approximately 6:36 p.m. on Sunday, the Bexar County Sheriff’s Office said.
Pearson was found to be breathing but unresponsive in her jail cell on Sunday, the sheriff’s office said.
On-site University Health medical personnel attempted “life-saving measures.” San Antonio fire crews and EMS officials also responded to the jail for additional assistance.
Pearson was later taken to the hospital where her health continued to decline.
“It does appear to be a medical episode, and it appears all policies and procedures were complied with at this time,” BCSO said.
The Castle Hills Police Department is investigating Pearson’s death, per the Sandra Bland Act. The Texas Commission on Jail Standards has also been notified of the death.
BCSO’s Internal Affairs Unit is conducting a separate, concurrent administrative review.
According to a KSAT Investigates analysis, Pearson is the fourth person to die while in the custody of the Bexar County Sheriff’s Office this year.
In January, Juan Plata Peña Jr., 49, died of complications stemming from a medical condition.
Peña, who was not at the Bexar County Adult Detention Center when he died, was a patient at a San Antonio-area hospital from Dec. 4, 2025, until his death on Jan. 3.
In February, Tammy Hovland, 59, died three weeks after she was attacked by her cellmate at the Bexar County Adult Detention Center. Hovland sustained head injuries as a result of the assault.
Last month, an inmate, later identified as Joshua Aaron Reyes, died by suicide. At the time, a sheriff’s office spokesperson said Reyes was found unresponsive in his cell by a BCSO supervisor conducting security checks.
