WASHINGTON COUNTY, Tenn. -

Washington County, Tennessee sheriff's investigators believe a lengthy medical history may have led to an inmate's death inside the jail.

According to Sheriff Ed Graybeal, 51-year-old Donna L. Patillo was brought into the detention center at 12:40 p.m. Tuesday afternoon by the Johnson City Police Department.

She had been arrested on a violation of probation warrants from Sumner County, Tennessee and was waiting to be transported to Sumner County.

Detention officers say they checked on Patillo in a holding cell 4:43 p.m. When officers went to serve her a meal at 4:52 p.m., they found her slumped over in her cell.

Patillo was taken to the Johnson City Medical Center where she was pronounced dead.

Sheriff Graybeal says Patillo had an extensive medical history and was prescribed several medications.

The Tennessee Bureau of Investigation has been called in to assist with the probe into Patillo's death.

This is the fifth inmate to die in the detention facility this year.
