Mr. SPECTER. Permit me to inject factors which we have not put on the record although it has been brought to your attention previously: Assume this is a 6.5-millimeter missile which was shot from a rifle having a muzzle velocity of approximately 2,000 feet per second, with a distance of approximately 160 to 200 feet between the weapon and the victim; and answer the prior question, if you would, Dr. Gregory, with those factors in mind? Dr. GREGORY. I would fully expect the first object struck by that missile to be very badly damaged, and especially if it were a rigid bone such as the wrist bone is, to literally blow it apart. I have had some experience with rifle wound injuries of the forearm produced by this type of missile, and the last two which I attended myself have culminated in amputation of the limb because of the extensive damage produced by the missile as it passed through the arm. Considerably more than was evidenced in the Governor's case either by examination of the limb itself or an examination of these X-rays. Mr. SPECTER. Now, as to the experience you had which you experienced which resulted in amputations, what was the range between the weapon and the victim's limb, if you know? Dr. GREGORY. The range in those two instances, I concede was considerably shorter but I cannot give you the specific range. By short I mean perhaps no more than 15 or 20 yards at the most. Mr. SPECTER. Would the difference between the 15 or 20 yards and the 160 to 250 feet make any difference in your opinion, though, as to the damage which would be inflicted on the wrist had that bullet struck it as the first point of impact? Dr. GREGORY. No, sir; I don't think it would have made that much difference. Mr. SPECTER. Do you know what the color was of the fragments in the wrist of the Governor, Dr. Gregory? Dr. GREGORY. As I recall them they were lead colored, silvery, of that color. I did not recall them as being either brass or copper. Mr. SPECTER. Are there any other X-rays of the Governor's wrist which would aid the Commission in its understanding of the injuries to the wrist? Dr. GREGORY. Only to indicate that there were two fragments of metal retrieved in the course of dealing with this wound surgically. For the subsequent X-rays of the same area, after the initial surgery indicate that those fragments are no longer there. And as I stated, I thought I had retrieved two of them. The major one or ones now being missing. The small one related to the bone or most closely related to the bone, and I will put back up here---- Mr. SPECTER. On the new X-rays which you put up, would you identify them first by indicating the date the X-ray was taken? Dr. GREGORY. Yes; the date of the X-ray is the same, November 22, 1963, and they may be identified as Exhibit "C" anteroposterior view postoperative, which is this one. Mr. SPECTER. Did they bear the same numbers, Dr. Gregory? Dr. GREGORY. They will bear the same numbers; yes.
