The two sets of pictures below were obtained by Fox 5 Atlanta. The first set of pictures, a ‘before’ pic shows a bag placed by the barricades next to a mailbox. In the ‘after’ picture, the bag is gone.
The next set of pictures show a man running away from the area where the bag was placed. Although it is possible that he was scared because of what had just occurred, it is a bit strange that while everyone around him seemed shocked, covering their ears and bending down, this man is seen running away in the opposite direction.
