WASHINGTON - Two Marines were shot and killed late Thursday at the Officer Candidate School at Marine Corps Base Quantico, and the suspected shooter, also a Marine, fatally shot himself inside a barracks on the base, authorities said.
The shooter gunned down a man before seizing a woman and killing her and then himself, officials said. They declined to publicly discuss a possible motive in the attacks, but said the incident was neither a terrorist incident nor an attempt to cause mass casualties.
They said the gunman and victims were members of the same unit and knew one another. "This was an isolated incident," said Capt. Eric Flanagan, a Marine spokesman at the Pentagon. "At no point was this suspected to be a mass shooting."
