Ballistics experiments (discussed more fully in app. X, [pp. 585-586]) showed that the rifle and bullets identified above were capable of producing the President’s head wound. The Wound Ballistics Branch of the U.S. Army laboratories at Edgewood Arsenal, Md., conducted an extensive series of experiments to test the effect of Western Cartridge Co. 6.5-millimeter bullets, the type found on Governor Connally’s stretcher and in the Presidential limousine, fired from the C2766 Mannlicher-Carcano rifle found in the Depository. The Edgewood Arsenal tests were performed under the immediate supervision of Alfred G. Olivier, a doctor who had spent 7 years in wounds ballistics research for the U.S. Army.[C3-158]
One series of tests, performed on reconstructed inert human skulls, demonstrated that the President’s head wound could have been caused by the rifle and bullets fired by the assassin from the sixth-floor window. The results of this series were illustrated by the findings on one skull which was struck at a point closely approximating the wound of entry on President Kennedy’s head. That bullet blew out the right side of the reconstructed skull in a manner very similar to the head wound of the President.[C3-159] As a result of these tests, Dr. Olivier concluded that a Western Cartridge Co. 6.5 bullet fired from the C2766 Mannlicher-Carcano rifle at a distance of 90 yards would make the same type of wound as that found on the President’s head. Referring to the series of tests, Dr. Olivier testified:
It disclosed that the type of head wounds that the President received could be done by this type of bullet. This surprised me very much, because this type of stable bullet I didn’t think would cause a massive head wound, I thought it would go through making a small entrance and exit, but the bones of the skull are enough to deform the end of this bullet causing it to expend a lot of energy and blowing out the side of the skull or blowing out fragments of the skull.[C3-160]
After examining the fragments of the bullet which struck the reconstructed skull, Dr. Olivier stated that—
the recovered fragments were very similar to the ones recovered on the front seat and on the floor of the car.
This, to me, indicates that those fragments did come from the bullet that wounded the President in the head.[C3-161]
The President’s Neck Wounds
During the autopsy at Bethesda Naval Hospital another bullet wound was observed near the base of the back of President Kennedy’s neck slightly to the right of his spine which provides further enlightenment as to the source of the shots. The hole was located approximately 5½ inches (14 centimeters) from the tip of the right shoulder joint and approximately the same distance below the tip of the right mastoid process, the bony point immediately behind the ear.[C3-162] The wound was approximately one-fourth by one-seventh of an inch (7 by 4 millimeters), had clean edges, was sharply delineated, and had margins similar in all respects to those of the entry wound in the skull.[C3-163] Commanders Humes and Boswell agreed with Colonel Finck’s testimony that this hole—
* * * is a wound of entrance. * * * The basis for that conclusion is that this wound was relatively small with clean edges. It was not a jagged wound, and that is what we see in wound of entrance at a long range.[C3-164]
The autopsy examination further disclosed that, after entering the President, the bullet passed between two large muscles, produced a contusion on the upper part of the pleural cavity (without penetrating that cavity), bruised the top portion of the right lung and ripped the windpipe (trachea) in its path through the President’s neck.[C3-165] The examining surgeons concluded that the wounds were caused by the bullet rather than the tracheotomy performed at Parkland Hospital. The nature of the bruises indicated that the President’s heart and lungs were functioning when the bruises were caused, whereas there was very little circulation in the President’s body when incisions on the President’s chest were made to insert tubes during the tracheotomy.[C3-166] No bone was struck by the bullet which passed through the President’s body.[C3-167] By projecting from a point of entry on the rear of the neck and proceeding at a slight downward angle through the bruised interior portions, the doctors concluded that the bullet exited from the front portion of the President’s neck that had been cut away by the tracheotomy.[C3-168]
Concluding that a bullet passed through the President’s neck, the doctors at Bethesda Naval Hospital rejected a theory that the bullet lodged in the large muscles in the back of his neck and fell out through the point of entry when external heart massage was applied at Parkland Hospital. In the earlier stages of the autopsy, the surgeons were unable to find a path into any large muscle in the back of the neck. At that time they did not know that there had been a bullet hole in the front of the President’s neck when he arrived at Parkland Hospital because the tracheotomy incision had completely eliminated that evidence.[C3-169] While the autopsy was being performed, surgeons learned that a whole bullet had been found at Parkland Hospital on a stretcher which, at that time, was thought to be the stretcher occupied by the President. This led to speculation that the bullet might have penetrated a short distance into the back of the neck and then dropped out onto the stretcher as a result of the external heart massage.[C3-170]
