Harrington, of Fitchburg, Massachusetts, was taken to an area hospital and is listed in critical condition. No other vehicles were struck during the crash. Authorities said others at the scene also assisted, including a turnpike employee and two motorists who carried Harrington out of the truck as police arrived. Fitzgerald said he had never used the defibrillator before Tuesday. "As a trooper, you see more negative than positive out there," Fitzgerald said. "It feels good when you can help someone and it feels good knowing that all those people had stopped to help before I got there."
