A stranger's Purple Heart holds a story of heroism and loss

This a remarkable, almost tear jerking story. All I can say is WOW!

Nancy Sasson was cleaning out her late parents' house in Miami, digging through clothes in a closet, when she found a military medal on the floor.
The Purple Heart had been given to Irvin S. Grindrod, a World War I Army veteran from Philadelphia.
It was a Purple Heart, typically awarded to military personnel wounded or killed in combat.
Wow, she thought, I had no idea my father had received a Purple Heart.
