The fire truck involved in a July 22 incident that injured three Hall County firefighters was sold by the fire department that owned it previously because of mechanical problems. The vehicle, a 2006 Sutphen, was sold back to the company in 2013 after Bluffton Township Fire District in Beaufort, S.C., determined “the truck poses too great a liability to maintain it” in the fleet, according to a 2013 Beaufort County Council report. The vehicle identification number for the truck owned by the Bluffton department matched the number listed for the truck involved last week with the injuries to Will Griffin, TJ Elliott and Stephen Jackson.
