The US Marine Corps Base at Quantico, Virginia, was placed on lockdown early on Friday after one person was killed in a shooting and a suspect barricaded in, the Marines said.
“An isolated shooting incident has occurred at Officer Candidate School, Quantico,” the base said on its Facebook page. “The suspect has been barricaded by law enforcement personnel, but is not currently under custody.”
Marine Corps spokesman Captain Eric Flanagan said one person had been killed in the incident but had no further details.
The Facebook message told base residents to remain in their homes with their doors locked.
