KNOXVILLE, Tenn. (WATE) — A woman who had become “unresponsive” while in Knoxville Police custody Sunday morning has died, according to Knoxville Police Department.

In an update shared Tuesday morning, Knoxville Police said the woman was identified as 60-year-old Lisa Edwards by the Tennessee Bureau of Investigation.

“At the request of District Attorney General Charme Allen and per standard department operating procedure, the Tennessee Bureau of Investigation will investigate the in-custody death,” Knoxville Police said Tuesday.

Knoxville police officers and a transportation driver were placed on administrative leave after Edwards became unresponsive while being taken to jail on Sunday, according to Knoxville Police Department spokesperson Scott Erland.

Erland said the officers responded to Fort Sanders Regional Medical Center around 7:40 a.m. after Edwards, who had been discharged, refused to leave an emergency room.

Officers put Edwards in the cruiser to take her to Roger D. Wilson Detention Facility to be booked on trespassing charges. According to Erland, she was not handcuffed and no force was used.

It was not clear how long Edwards was in the police car when the officers noticed she became unresponsive. When she was taken to the hospital Sunday, she had been listed in critical condition.

Fort Sanders Regional Medical Center released a statement on Tuesday stating, “Patient care and privacy are of the highest importance at Fort Sanders Regional. We cannot share specific details of the patient’s care, but we want to extend our deepest sympathy to the family in their loss. We are continuing to gather information and are cooperating with local law enforcement in their investigation.”

Internal Affairs Unit with Knoxville Police Department will conduct an internal administrative review to determine if any policies or procedures were violated.
