Three men who pleaded guilty to robbing an armored vehicle in January outside of the Wal-Mart store in Oakwood received prison sentences Wednesday from Senior U.S. District Judge William C. O’Kelley. Terry Lamar Rivers, 20, Antonio Cequan Gore, 21, and Montez Antwan Walker, 26, all of Atlanta, were indicted by a federal grand jury in February on a charge of robbery affecting interstate commerce. They each pleaded guilty in May.
