The entrance to the U.S. Marine Corps Base Quantico Friday March 22, 2013. Three people, including the suspect, were killed in a shooting at Marine Base Quantico, base spokesman Lt. Agustin Solivan said early Friday.
Officials say a Marine killed a male and female colleague at Marine Base Quantico in Virginia before committing suicide on Thursday night.
Base Commander Col. David Maxwell says the incident began around 10:30 p.m., when a 911 call alerted authorities to a shooting that killed one. The base was placed on lockdown as authorities addressed the threat.
A base spokesman initially described the situation as a standoff. Maxwell said later in the morning that there was no standoff.
Base spokesman Lt. Agustin Solivan later clarified that after the first shooting, police had the shooter "isolated'' in a barracks dorm room.
"This is truly a tragic loss for the Marine Corps, which has had a number of tragic losses in the last couple of weeks," says Maxwell. "I want to express my sincere condolences to the families, the friends and the Marines of the three Marines we lost last night."
Authorities eventually entered the barracks early Friday and found a second victim dead, along with the suspect, dead of a self-inflicted gunshot wound.
The names of the three dead Marines will not be released until next of kin have been notified, Maxwell says.
The shooting appears to have stemmed from a personal dispute, according to NBC Washington, and Marine Corps officials are calling it an "isolated incident."
The base, which is about 37 miles south of Washington, is also home to the FBI's training academy.
In 2010, the base was one of several targets of an ex-Marine reservist who, during five nighttime shootings, fired on military targets including the Pentagon. Yonathan Melaku, on two separate occasions, fired at the National Museum of the Marine Corps in Quantico. No one was injured and Melaku was ultimately sentenced to 25 years in prison.
