Surveillance video from a Maryland business shows one of two critically wounded Navy sailors staggering inside the establishment moments after he was shot Tuesday near the Army base where he is assigned.
Authorities said Fantahun Girma Woldesenbet, 38, a Navy Hospital Corpsman, began shooting a rifle at an office park before driving 10 minutes away to Fort Detrick, where he was killed by personnel.
Moments after the shooting, the wounded sailor entered Nicolock, a paving manufacturer, in uniform and appeared to warn two men behind a counter of what was happening. He then opened a door and entered a room.
The two men walk to the front door and appeared to lock themselves in. Calls to the Nicolock location from Fox News were not answered.
Investigators have not determined a motive for the shooting. U.S. Army Garrison Fort Detrick announced that the suspect "breached the Nalin Pond gate located off of Opposumtown Pike," and made it onto the base, where he was fatally wounded.
Woldesenbet allegedly brandished his weapon at Fort Detrick civilian police personnel who fatally shot him.
One of the wounded sailors was released from a hospital hours later and the other remained in critical condition, the Navy said.
In a statement, the Navy said it was sending "our deepest condolences to all affected by this terrible act of violence and will continue to support the investigation."
Fort Detrick is home to the military’s flagship biological defense laboratory and several federal civilian biodefense labs. About 10,000 military personnel and civilians work at the garrison, which encompasses about 1,300 acres in the city of Frederick.
