Kimberly Phillips, who was identified by the medical examiner’s office, was under medical observation while at the Tarrant County Jail, according to the release. She was taken to John Peter Smith Hospital on Feb. 15 and died three days later “under the direct care of the medical staff,” the release states.

A second person has died in the Tarrant County Jail this year after spending days in Fort Worth's John Peter Smith Hospital with an unspecified medical issue.
