Police in Virginia say shots have been fired at the National Museum of the Marine Corps, the fourth time someone has fired at government buildings in the area. Multiple shots were fired sometime after the museum, located about 30 miles south of the Pentagon, closed last night, police say.
Bullet holes were first found at the museum Oct. 17. The Defense Department and a Marine Corps recruiting station have also been hit, and the FBI says the same gun was used in all three cases. No one was hurt in any of the shootings. (Read more Marines stories.)
