Authorities have not identified a soldier who barricaded herself in a building at Fort Lee, Virginia, and fatally shot herself in the head as law enforcement officials tried to negotiate with her.
Fort Lee went on lockdown while the soldier was holed up on the third floor of a four-story building.
About 1,100 other people were inside, but no one else was hurt.
She had been in the Army for 14 years.
Army officials say they don't know whether the soldier was being treated for mental health issues.
