The call came in to police around 11:15 a.m., stating that a young male wearing a black ski mask and holding something that looked like an assault rifle was spotted in the Madison Manor neighborhood. The teen and a companion were heading toward the pedestrian bridge that crosses I-66 near Ohio Street, just east of East Falls Church on the W&OD trail.
Police officers swarmed the area. At least three witnesses reported seeing the same teen, who was accompanied by another young male who was carrying a camera bag and a camera.
