GBI Agent Mike Ayers says 29-year-old Chris Calhoun assaulted a construction foreman who showed up for work this morning at a building under construction near the Gateway Cinemas off Hwy. 316. That is near the same area where Calhoun wrecked the car belonging to the 81-year-old woman Sunday following a police chase. The woman, who was still inside the trunk at the time, suffered minor injuries.
