Three active duty Marines are dead following a late night shooting on the Quantico Marine Base in Quantico, Virginia. The shooting led to the lockdown of the entire Marine base from 11 p.m eastern until early Friday morning. The alledged gunman was holed up inside a building with a victim. A Marine Corps spokesman says the gunman, who was a staff member at the Officer Candidate School, is among the dead.
