An escaped Tennessee inmate convicted of murdering a co-worker stole a truck from a nearby farm and apparently made it to southern Illinois before abandoning it, authorities said Tuesday.

Jacob Morley, who was serving a life sentence for killing a co-worker four years ago, was found to be missing from the Northwest Correctional Complex late on Sunday.

The Tennessee Bureau of Investigation released surveillance video from the farm, which is near Tiptonville and about a 2-mile (3-kilometer) walk through fields from the prison, showing Morley open the truck's unlocked driver's side door and drive off at about 1 a.m. Monday.
