(Reuters) – A Marine shot dead two fellow service members at a base in Quantico, Virginia, then killed himself, the Marines said on Friday.

The shootings took place late on Thursday near the officer candidate school at the Marine Corps base in Quantico, and all three people who died were active-duty Marines, base commander Colonel David Maxwell said.

“The shooter, an active-duty Marine, was pronounced dead of a self-inflicted gunshot wound by law enforcement at the scene,” he told a news conference carried by local media.

Maxwell gave no motive for the shooting and an investigation is under way. The two slain Marines, a man and a woman, were permanent personnel assigned to the officers school, as was the shooter, he said.
