The FBI says the latest shooting at a military building in the Washington area is connected to four other shootings reported last month.
The fifth shooting, at a Coast Guard recruiting station at a suburban Washington shopping mall, was reported Tuesday. No one has been injured in any of the shootings.
Lindsay Godwin, a spokeswoman for the FBI's Washington field office, said Wednesday that investigators have not identified a suspect. Details about the kind of weapon used have not been disclosed.
Last month overnight shootings were reported at the National Museum of the Marine Corps, the Pentagon, and a Marine Corps recruiting station. The museum was targeted twice.
