Walker County Jail

A female inmate at the Walker County Jail died last week after doctors were unable to revive her following a seizure.

Jail surveillance footage shows that 22-year-old Symone Marshall suffered a seizure on May 10 in the women's cell block and other inmates immediately alerted jail staff by pushing an emergency button on the wall. In less than a minute, staff members were in the room and began providing medical attention.

Marshall was transported to Huntsville Memorial Hospital, where she was later pronounced dead.

"Our condolences go out to Ms. Marshall's family," Walker County Sheriff Clint McRae said. "At our request, we have asked Texas Ranger Steve Jeter to assist in investigating the incident, which it is customary to bring in an outside agency to handle any allegations that may be made."

Investigators are still awaiting autopsy results, but McRae said the preliminary results showed no signs of external injuries.

Marshall, whose address was listed at a residence on Trinity Cut Off in Huntsville, was being held on two charges of possession of a controlled substance and failure to identify by giving false or fictitious information stemming from a one-vehicle rollover accident on Interstate 45 on April 26. She and another woman in the car signed a waiver declining medical attention at the scene of the accident.

Marshall was taken into custody after a Texas Department of Public Safety trooper searched the vehicle and found narcotics.

She had been in jail for more than two weeks on a $5,000 combined bond when she had the seizure.

"Eight days prior to her death, Ms. Marshall had seen a doctor one day and a nurse the other," said Detective Brad Fullwood with the Sheriff's Office. "She did not have any injuries and did not have any complaints."
