US Marine Kills Two Colleagues At Quantico Base

A Marine opened fire on two of his comrades Thursday night at a base in Quantico, Va., before turning the gun on himself, leaving all three dead, military officials said.

A relationship dispute was believed to be behind the shooting, which occurred in the staff barracks area of the Officer Candidates School at Marine Corps Base Quantico in Northern Virginia, a Marine official said.

The assailant and both victims, a man and a woman, were staff members at the school and not students, a senior defense official said. The official called the incident "isolated," adding: "There was nothing random here."
