A 29-year-old Afghan national named Rahmanullah Lakanwal has been identified as the suspected shooter in the ambush that wounded two National Guard troops in D.C., officials say.
A bystander helped the pair on the beach, but the woman died at the scene. A paramedic said the bystander's first aid might have prevented a double fatality.
Two members of the West Virginia National Guard were shot a few blocks from the White House, and a suspect identified as an Afghan national is in custody.
