A Marine killed a male and female colleague in a shooting at Quantico, a military base in northern Virginia, before killing himself, according to reports.
The tragedy began with a shooting around 11 p.m. Thursday that left one dead at Marine Base Quantico, base spokesman Lt. Agustin Solivan said.
That shooting led to a standoff between authorities and the suspect, who was barricaded in barracks at the base. Authorities entered early Friday.
They found the suspect dead of a self-inflicted gunshot wound along with a second victim.
Solivan did not say what prompted authorities to enter the barracks. No names were immediately released but Solivan said the suspect and both victims were Marines.
Authorities believe the suspect was a staff member at the officer candidate school.
Solivan said the shooting was isolated and there were no other casualties. The base was on lockdown after the shooting but the lockdown was lifted early Friday.
During the lockdown, residents were warned over a loudspeaker to stay inside.
About 37 miles south of D.C., Quantico also home to the FBI’s training academy.
In 2010, it was one of several targets of an ex-Marine reservist who, during five nighttime shootings, fired on military targets including the Pentagon.
