MEMPHIS, Tenn. (AP) — Tennessee police officials on Sunday identified a suspect in the fatal shooting of a Memphis police officer, and an intense search for the man is underway. Tremaine Wilbourn, 29, faces a first-degree murder charge in the death of Officer Sean Bolton, 33, on Saturday night, Memphis Police Director Toney Armstrong said at a news conference. Armstrong said Wilbourn was a passenger in a 2002 Mercedes Benz that was parked illegally in a southeast Memphis neighborhood on Saturday night. Armstrong said Bolton saw the car and shined his squad car's spotlight on the vehicle.
