@dailymail: This is the moment a soldier returned from service in the Iran war to surprise her younger brother at his high school graduation in Wisconsin. As Kalen Barksdale walked across the stage to receive his diploma from Milwaukee Lutheran High School, a school official stopped him and announced that his diploma could not be found. The delay was part of the surprise. Moments later, his sister, U.S. Army Specialist Mauriana Barksdale, who had been deployed overseas with the Wisconsin National Guard, appeared on stage and presented him with his diploma. #graduation #usa #iran
