MACON, Miss. (WCBI)-Macon police have a ‘person of interest’ in custody after a robbery at the Oak Tree Inn on Highway 45 North. The crime happened last Friday night. The attendant says a masked man came in with his hand in his pocket and said, quote, ” You know what this is.” He never showed a gun, but the attendant thought he had one. He made off with the money from the register. Police caught up with a ‘person of interest’ on Saturday, but have yet to formally charge him. The investigation continues.
