WASHINGTON — The same gun was used to shoot at the Pentagon and the National Museum of the Marine Corps in northern Virginia earlier this month, the FBI said Tuesday.
A third military office — a Marine Corps recruiting station in Chantilly, Va., outside Washington — was shot at overnight Monday; Marines who work there discovered the shooting Tuesday morning, the FBI said. Investigators are conducting ballistics tests to determine whether the recruiting station shooting is related to the previous incidents.
No one was injured in any of the shootings.
Investigators haven’t determined a motive or identified a suspect, said Lindsay Godwin, spokeswoman for the FBI’s Washington field office.
Although all three shootings have targeted offices with links to the military, Godwin said the FBI has not issued any specific advisories or warnings to recruiting stations or other military buildings.
The FBI declined to identify the type of weapon or ammunition used in the first two shootings to avoid compromising its investigation. Officials earlier described the weapon used in the Pentagon shooting as a high-velocity rifle.
