On Monday morning, August 30, 2010, Thomas Richard Cowan loaded 13 bullets into two handguns, left his German shepherd chained to the fence and drove eight miles from his home in Kingsport to Sullivan Central High School. Whatever his mission, it was the 62-year-old Vietnam veteran’s final drive. For about an hour, Cowan’s armed invasion spread panic throughout the school before a burst of officers’ gunfire brought him down. No others were injured.
