Two workers at the Washington, DC Naval Yard told NBC News on Monday that they encountered a gunman who reportedly killed at least four people and injured at least 10 others in a hallway when he silently raised his gun and opened fire on them.
Terrie Durham and Todd Brundivge, civilian co-workers at the Office of Naval Sea System Command, said they were about 40 yards from the gunman but were able to see that he was dressed in blue and carrying a weapon.
"He was a tall man, appeared to have dark skin, looked like he was in some kind of uniform and he had a rifle," Durham told NBC, adding that the stairwell she was standing in was dimly lit and it was difficult to see the gunman's face.
"No words. He raised the gun and started firing," Brundvige recounted. "He said nothing."
The gunman opened fire on Durham and Brundvige, but aimed too high and missed.
"We're lucky he was far enough away he was a bad shot," Durham said.
