Three Dead in Murder-Suicide at Quantico Marine Base

Authorities in Quantico, Va., have lifted a area-wide lockdown after a Marine who shot and killed two co-workers was found dead of a self-inflicted gunshot. The suspect, who was not yet identified, shot two people at around 11:00 p.m. on Thursday night at Marine Corps Base Quantico. After a standoff that lasted several hours, fellow soliders entered the barracks and found the shooter had committed suicide.

The Quantico base, which is about 30 miles south of Washington, D.C., is famously known as the primary training ground for both the Marine Corps and the FBI. It's referred to as the "Crossroads of the Marine Corps," since most officers and soliders who receive advanced training pass through there at some point during their careers. 

The two victims were also Marines, but their connection to the shooter has not yet been revealed. The only other information given about the shooter is that he was a staff member at the officer candidate training school on the base.
