Mr. O'Donnell. Yes; the first two came almost simultaneously, came one right after the other, there was a slight hesitation, then the third one.
Mr. Specter. And what was your reaction as to the source of the shots, if you had one?
Mr. O'Donnell. My reaction in part is reconstruction—is that they came from the right rear. That would be my best judgment.
Mr. Specter. Was there any reaction by any of the other people around in any specific direction?
Mr. O'Donnell. The agents all turned to the rear. I would think, watching the reaction of the President when the shot—the first shot hit—that it would be automatic it would have to have come from the rear. I think any experienced agent would make that assumption immediately.
Mr. Specter. And was the reaction of the agents which you have referred to as coming from the rear, to the right rear or to the left rear?
Mr. O'Donnell. The reaction I note would be right rear. And, again, looking at the manner of the President's movement, I would think you would have to feel the thrust of the shot was from the right rear.
Mr. Specter. Now, what was there about the President's movement which leads you to that conclusion?
Mr. O'Donnell. He was leaning out waving. He may have just been withdrawing his hand. And the shot hit him, and threw him to the left. He slumped on Mrs. Kennedy.
Mr. Specter. Were you able to determine a reaction on that slumping movement, as to whether it was the first, the second, or the third shot?
