An airman assigned to Little Rock Air Force Base has been killed in Iraq. The Defense Department says Staff Sergeant Dustin W. Peters of El Dorado, Kansas, was killed in action Sunday morning. An Air Force Spokesman tells KARK 4 News he was killed when the convoy he was riding in encountered an explosive device. Peters had been in the Air Force since 1997. He was assigned to the 332nd Air Expeditionary Wing and attached to the Army`s 494th Truck Company at Balad Air Base. Before arriving at Little Rock Air Force Base in 2000, he had been stationed in Lackland Air Force Base in Texas and Fort Leonard Wood, Missouri. Peters left the Jacksonville Base for Iraq back in February. A private memorial service will be held at Little Rock Air Force Base Thursday afternoon.
