Authorities in Tennessee launched an intense manhunt for a convicted murderer who they said escaped from a state prison, stole a work truck and remains on the loose.

Jacob Allen Morley, 28, escaped from the state’s Northwest Correctional Complex in Tiptonville sometime before he was reported missing at 11:30 p.m. Sunday, prison officials said in a statement Monday.
