I agree that it was most likely a camera glitch. I don’t think an apparition would have that kind of appearance. And the more I look at the pictures, the more I realize that the man affected by the glitch happens to be mostly in the same area of the canera’s frame. Originally, I thought he was off to the left in the second picture and out of the center of the frame, but he really isn’t. Of course, there’s still the question of why him?
