Authorities have determined that the shots fired at the National Museum of the Marine Corps and the Pentagon earlier this month came from the same weapon, the FBI announced Tuesday.
The FBI opened an investigation into those shootings and one that occurred overnight at the Marine Corps Recruiting Station in Chantilly, Va. Property damage at the recruiting office at 13881 Metro Tech Drive was reported at about 8:30 a.m. when an employee discovered two apparent bullet holes in a window.
Ballistics testing is under way to determine if that shooting is connected to the other two. Police canvassed the area for evidence Tuesday. Much of the shopping center where the recruiting station is located was taped off.
Shots were fired at the Marine Corps Museum in Triangle, Va., during the early morning hours of Oct. 17. Several glass panels were struck, but none of the museum's artifacts was affected.
Just before 5 a.m. on Oct. 19, officers at the Pentagon in Arlington, Va., reported hearing shots in the area of the south parking lot, which faces Interstate 395. Fragments of two bullets were found embedded in windows on the third and fourth floors. They shattered but didn't penetrate the reinforced-glass windows, which were part of unoccupied offices. Four other bullets struck the Pentagon's façade.
Authorities have not said what type of weapon or caliber ammunition was used in the shootings.
