Two shootings that targeted U.S. military buildings in Northern Virginia have been conclusively linked to the same weapon, and law enforcement officials think a third attack on a Marine Corps recruiting office this week could be part of the same unexplained spree.
Law enforcement officials announced Tuesday that ballistics tests linked bullets found at the National Museum of the Marine Corps in Triangle on Oct. 17 with evidence found at the Pentagon two days later. Both buildings are within range of busy interstate highways and are about 30 miles apart.
Law enforcement officials declined to discuss the type of weapon used in the shootings or the caliber of ammunition, but they have said previously that they believe the rounds were fired using a high-velocity rifle.
The FBI’s Joint Terrorism Task Force has taken the lead in the investigation. Agents are working to do ballistics testing on material found at the scene of a shooting at a Marine Corps recruiting office in a Chantilly shopping center late Monday or early Tuesday. A Marine Corps recruiter found two bullet holes in the office’s windows at 8:30 a.m. Tuesday, although a Marine Corps official said the office has been closed for renovations.
Police say they are unsure what is motivating the shootings, and they are reluctant to speculate.
