Senator Cooper. Can you see it?
Mr. Kellerman. Yes; oh, yes, sir.
Senator Cooper. Can you see the viaduct plainly?
Mr. Kellerman. Oh, yes, sir.
Senator Cooper. Could you tell whether anybody was standing on top of the viaduct, or did you observe?
Mr. Kellerman. I didn't notice anybody up there at all, sir.
Senator Cooper. Did you observe whether anyone was in the immediate vicinity of the viaduct?
Mr. Kellerman. Not at this distance; no.
Senator Cooper. Do you have any—at the time of the shots, at the time that you were conscious of these shots being fired, do you have any judgment as to from what direction they came?
Mr. Kellerman. None whatsoever. Except I should say again that when this first one went off, which I indicated here that it sounded like a firecracker to my right and, say, rear, I looked to my right to see what it was.
