Prince William County police are saying that yet more shots were fired upon the National Museum of the Marine Corps in Triangle overnight, the second time that an unknown person or people have fired on the building and the fourth such incident of gunshots aimed at Virginia military-related buildings over the last twelve days. No injuries were reported and the gunfire occurred after the Museum was closed. The first shooting at the Museum occurred on October 17; since then (and before this news), gunshots had hit the side of the Pentagon (October 19) and a Marine recruiting center in Chantilly (October 26). All three of those incidents have been linked to the same weapon. Investigators are on the scene of the Museum this morning to see if they can get any clues as to whether this shooting is linked as well.
