Representative Ford. Are you sure that the sound you heard came from the rear and not from the front?
Mr. Lawson. I am positive that it came from the rear, and then I spun back that way to see what had occurred back there.
Mr. Dulles. Could you tell at all whether the sound came from above you?
Mr. Lawson. No; I could not. It was quite a general loud bang, an echoing-type bang.
Representative Ford. At the time of the sound you were within 15 or 20 feet of the overpass approximately?
Mr. Lawson. I was quite close to the overpass, yes, sir; but I don't know exactly how close.
Representative Ford. You are sure that the sound didn't come from the overpass?
Mr. Lawson. I am in my own mind that it didn't. It came from behind me. Then I heard two more sharp reports, the second two were closer together than the first. There was one report, and a pause, then two more reports closer together, two and three were closer together than one and two.
Mr. Stern. What else did you observe when you looked back?
Representative Ford. May I ask a question here. Had you turned around by the time the second and third shots had been fired?
