Hong Yung, 34, of Beltsville, Maryland, is charged with attempted first-degree assault, firearm in the use of a violent felony crime, handgun in vehicle, and reckless endangerment.
The police say they believe Yung is responsible for firing shots at the NSA building from the nearby Baltimore-Washington Parkway and also for firing at a vehicle on another highway where shattering glass slightly injured the driver. Yung is also suspected in a shooting outside an area store and movie theater. No other injuries have been reported.
Law enforcement officials don’t yet have a motive for the shootings, but say they don’t believe the shootings were related to national security or terrorism. Yung was evaluated at a psychiatric facility when he was arrested.
He was arrested after what police describe as “hiding in plain sight.” On Tuesday evening after two shootings were reported, officers spotted a vehicle that matched the description of the one used in the shootings near where one of the incidents happened, and when they pulled Yung over, police found shell castings and a semi-automatic handgun in plain view that were later matched to the casings in the shooting incidents.
Maryland authorities say Yung was a correctional officer for two years before resigning without incident in May of last year.
Yung is being held without bail at a detention center near Baltimore, Maryland and has a court hearing scheduled for the week of March 9.
