A shooting at Marine Base Quantico on Thursday, March 21, left three Marines dead, according to CBS News.
The base was put on shutdown following the shooting, which happened at about 11 p.m. Names of the victims have not yet been released.
The suspect, believed to be a staff member at the officer candidate school on base, then barricaded himself in the barracks, resulting in a standoff between the suspect and the authorities.
Authorities entered the barracks early on Friday morning and found the suspect and a second victim dead. Base spokesman Lt. Agustin Solivan could not say why authorities entered the barracks.
The shooting took place on the same day military officials met before the House Armed Services Committee's Subcommittee on Military Personnel Subcommittee on Capitol Hill to discuss efforts to reduce suicide in the military.
According to Stars and Stripes, officials from all services are working together at the Department of Defense's Suicide Prevention Office, which opened in 2011.
The Army experienced a record 324 suicides in 2012, including 183 active military members. Army Lt. Gen. Howard B. Bromberg, deputy chief of staff for manpower and personnel was one of those testifying on Thursday.
Bromberg stated that the Army has been tracking an infantry unit whose members participated in resiliency training to see the outcome.
The findings to date show that the number of peer-to-peer interventions is up, although suicidal gestures remain the same.
Parents of military members and the military community have shown extreme concern about the rise in suicides. Annual "Never Leave a Marine Behind" suicide prevention training is required for all Marines.
