Surveillance video from a Maryland company shows one of the two seriously injured Navy sailors staggering inside the facility moments after he was shot Tuesday near the army base where he is stationed.
Authorities said Fantahun Girma Woldesenbet, 38, a Navy hospital corpsman, began firing a rifle in an office park before driving 10 minutes to Fort Detrick, where he was killed by personnel.
Moments after the shooting, the wounded sailor walked into Nicolock, a pavement maker, in uniform and appeared to warn two men behind a counter what was happening. Then he opened a door and entered a room.

The two men walked to the front door and seemed to lock themselves in. Calls to Nicolock’s location from Fox News were not returned.
Investigators have not determined a motive for the shooting. The US Army garrison Fort Detrick announced that the suspect “passed through the Nalin Pond gate located opposite Opposumtown Pike” and arrived at the base, where he was mortally wounded.
Woldesenbet allegedly brandished his weapon at Fort Detrick civil 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.
