Assume, if you will, that President Kennedy was shot on the upper right posterior thorax just above the upper border of the scapula at a point 14 cm. from the tip of the right acromion process and 14 cm. below a tip of the right mastoid process, assume further that that wound of entry was caused by a 6.5-mm. missile shot out of a rifle having a muzzle velocity of approximately 2,000 feet per second, being located 160 to 250 feet away from President Kennedy, that the bullet entered on the point that I described on the President's back, passed between two strap muscles on the posterior aspect of the President's body and moved through the fascial channel without violating the pleura cavity, and exited in the midline lower third anterior portion of the President's neck, would the hole which Dr. Perry described to you on the front side of the President's neck be consistent with the hole which such a bullet might make in such a trajectory through the President's body? Dr. McCLELLAND. Yes; I think so. Mr. SPECTER. And what would your reasoning be for thinking that that would be a possible hole of exit on those factors as I have outlined them to you? Dr. McCLELLAND. Well, I think my reasoning would be basically that the missile was traveling mainly through soft tissue, rather than exploding from a bony chamber and that by the time it reached the neck that it had already lost, because of the distance from which it was fired, even though the muzzle velocity was as you stated--would have already lost a good deal of its initial velocity and kinetic strength and therefore would have perhaps made, particularly, if it were a fragment of the bullet as bullets do sometimes fragment, could have made a small hole like this in exiting. It certainly could have done that. Mr. SPECTER. What would have happened then to the other portion of the bullet if it had fragmented? Dr. McCLELLAND. It might have been left along, or portions of it along the missile track--sometimes will be left scattered up and down this. Other fragments will maybe scatter in the wound and sometimes there will be multiple fragments and sometimes maybe only a small fragment out of the main bullet, sometimes a bullet will split in half--this is extremely difficult for me to say just what would happen in a case like that. Mr. SPECTER. Well, assuming this situation--that the bullet did not fragment, because the autopsy report shows no fragmentation, that is, it cannot show the absence of fragmentation, but we do know that there were no bullets left in the body at any point, so that no fragment is left in.
