Lupita Hernandez, 38, was alone when her body was discovered, Tarrant County Sheriff’s Department representative Terry Grisham said. Records indicated Hernandez died at 9:43 p.m. Saturday in a jail cell at the Tarrant County Corrections Center on North Lamar Street, but Grisham later said she was inside the medical unit of the jail when she died.

There are two medical units — one for men and one for women. The medical unit is a 33-bed facility operated by John Peter Smith Hospital to provide medical services, according to Grisham.

Grisham did not say what Hernandez was being treated for, but did confirm officers found no obvious signs of trauma. Grisham earlier said Hernandez did not die as a result of a fight.

The Tarrant County Medical Examiner will determine the cause and manner of death. The department is awaiting those results.

The department will conduct an internal investigation and send the report to the Texas Attorney General for review, Grisham said.
