PAWNEE COUNTY, Okla. – Agents with the Oklahoma State Bureau of Investigation are looking into the death of an inmate at an Oklahoma jail.

Around 3 a.m. on Tuesday morning, officers with the Pawnee Police Department arrested 26-year-old Brittany Weide DeVerges for public intoxication and possession of paraphernalia.

DeVerges was booked into the Pawnee County Jail and placed in a detox cell.

Authorities checked on DeVerges around 10:30 a.m. and determined that she needed to remain in the detox cell a little longer.
