Mr. Jackson. Down Elm Street toward the triple, toward the underpass.
Mr. Specter. Was it pointed as you have indicated at the angle which Elm Street traverses heading toward the triple underpass?
Mr. Jackson. Yes, sir. And the rifle was pointing slightly down.
Mr. Specter. Did you at any time in this sequence observe the President's automobile?
Mr. Jackson. As we turned the corner—or we stopped where the intersection, actually we stopped before we began to turn left onto Elm Street, or rather I would say we hesitated and we were all looking down towards the President's car and I could see two cars going under the underpass. I barely saw the President's car. I would say just the rear end of it as it disappeared under the underpass.
Mr. Specter. Was that the only time you saw the President's car from the time you made a right-hand turn off of Main Street onto Houston Street?
Mr. Jackson. Yes, sir.
Mr. Specter. What is your best estimate as to the time span between the first shot you heard and the last shot you heard?
Mr. Jackson. I would say 5 to 8 seconds.
Mr. Specter. Can you give us a breakdown between the shots which you heard as to how many seconds elapsed between each one?
