Chambersburg. (AP) A Pennsylvania state trooper was shot while conducting a traffic stop in Franklin County early Feb. 29, authorities said. The trooper, who was not identified, was flown to a hospital and listed in stable condition. The shooting happened shortly after 2 a.m. at the 1400 block of Lincoln Way East in Guilford Township. It came after troopers stopped a driver who was suspected of driving under the influence. During a sobriety test, an altercation broke out between the troopers and the driver, Robert William Ransom, 20, of Chambersburg, according to a news release from the Pennsylvania State Police. While the troopers were trying to arrest him, Ransom pulled out a handgun and shot one of them, the release said. Ransom was taken into custody uninjured. It's not clear whether Ransom has yet to secure legal representation.
