OKLAHOMA CITY (AP) — The Oklahoma County Sheriff's Office says a 35-year-old inmate at the county jail has died.

Authorities say Blaine Petrie was found unresponsive shortly after 10 p.m. Monday in a cell at the jail. Correctional staff and paramedics attempted life-saving measures, but Petrie was pronounced dead at 10:25 p.m. Petrie's cellmate says he thought Petrie was sleeping and did not report anything suspicious.

Public Information Officer Mark Opgrande says Petrie was booked into the jail at 10:46 p.m. Sunday on a driving under the influence complaint following a collision.
