Mr. Barnett. Three.
Mr. Liebeler. Was there any echo in the area from where you were standing?
Mr. Barnett. What do you mean by echo? You mean another sound besides the shots?
Mr. Liebeler. Yes.
Mr. Barnett. No; I didn't hear any echo. The whole sound echoed. The sound lingered, but as far as just two definite distinct sounds, when each shot was fired, that one sound would linger in the air, but there would be nothing else until the next shot.
Mr. Liebeler. Did you see any of the shots hit the President?
Mr. Barnett. Well, when the first shot—I was looking at the President when the first shot was fired, and I thought I saw him slump down, but I am not sure, and I didn't look any more then. I thought he was ducking then.
Mr. Liebeler. Now when you were standing up there in position No. 9, you were in a spot where you could look right down Elm Street and see the railroad tracks down here which pass over the triple underpass?
Mr. Barnett. Yes, sir.
Mr. Liebeler. Did you see anybody on the railroad tracks?
