Wounded War Veteran Carries Woman Across Boston Marathon Finish Line

The Boston Marathon is difficult to get through, but this veteran is as tough as they come.

Former Army Staff Sgt. Earl Granville carried a woman across the finish line while she held the American flag. Granville, who lost one of his legs during his third deployment in Afghanistan, completed the marathon and helped out a fellow runner along the way. 

A true hero's work is never done.
