The shooting comes four days after seven Marines were killed in an explosion in Nevada
At a base in Virginia near Washington D.C., a Marine shot and killed two fellow Marines, and then killed himself. USA Today has the story:
A Marine shot and killed two fellow Marines at a barracks near Washington, D.C., late Thursday and early Friday then took his own life, according to the commander of Marine Corps Base Quantico.
All three, including a male and a female hostage, were active duty Marines assigned to the Officer Candidate School, according to Col. David Maxwell, the base commander.
"This is truly a tragic loss again for the Marine Corps, which has had a number of tragic losses in the last couple of weeks," he said.
The shooting came four days after seven Marines were killed when a mortar exploded during a training exercise Monday night at a training facility and Army munitions depot in Nevada.
