(WASHINGTON) -- The FBI's Washington Field Office confirmed Wednesday that all five military-related shootings in Northern Virginia -- at the Pentagon, the Marine Museum and two military recruiting stations -- have all been linked.
Officials involved in the FBI investigation say they have determined that bullets from all five shootings appear to have been fired from the same weapon, according to ballistics results from the FBI Laboratory at Quantico.
Investigators on the case speculated Tuesday morning that recent media attention may have caused copycats to emerge. However, after Wednesday's ballistics results, the search for suspects continues to narrow.
No one has been injured in any of the five incidents.
