A Tennessee Highway Patrolman today captured a male inmate who escaped from a prison work detail at Roan Mountain State Park. Brian D. Knighton, 34, a prisoner from the Northeast Correctional Complex-Annex in Mountain City, stole a state-registered 2007 Dodge Caravan, changed the license plates, and fled the upper East Tennessee state park just after 3:30 p.m. on Tuesday, September 28. All THP units in the Cookeville District were instructed to “be on the lookout”, and by Wednesday morning, Trooper Erick McCormick (pictured above) noticed the vehicle at the Marathon Gas station located on South Jefferson Avenue in Cookeville. Trooper McCormick, who was assisted by additional State Troopers, took the subject into custody just before 11 a.m. Wednesday morning. The Tennessee Bureau of Investigation (TBI) and the Tennessee Department of Correction (DOC) are investigating. Knighton is serving an 18-year theft and aggravated burglary sentence from Moore and Bradley counties. He was scheduled for release in 2015. An escape charge is expected.
