For 1 sentinel, a final walk at Arlington's Tomb of the Unknown Soldier

For the last two years, Army Sgt. 1st Class Andrew Jay has been dutifully guarding the Tomb of the Unknown Soldier at Arlington National Cemetery. With Jay's final walk scheduled for June 2, this Memorial Day will hold special significance for him as the cemetery prepares for a string of events honoring those who paid the ultimate price for their country.
