Dr. GREGORY. It is my understanding from conversations with Dr. Shaw, and I believe his medical reports bear this out, that the fifth rib was literally shattered by the missile. We know that high velocity bullets striking bone have a strong tendency to shatter bones and the degree to which the fifth rib was shattered was considerably in excess of the amount of shattering which occurred in the radius--the forearm. Mr. SPECTER. And what conclusion, if any, did you draw as to the velocity of the missile, as to the time it struck each of those bony portions? Dr. GREGORY. I think that the missile was continually losing velocity with each set of tissues which it encountered and transected, and the amount of damage done is progressively less from first entrance in the thorax to the last entrance in the thigh. Mr. SPECTER. Do you think it possible that Governor Connally was shot by two bullets, with one hitting in the posterior part of his body and the second one striking the back side of his wrist? Dr. GREGORY. The possibility exists, but I would discount it for these reasons--ordinarily, a missile in flight--I'll qualify that--a high velocity missile in flight does not tend to carry organic material into the wound which it creates. I believe if you will inspect the record which was prepared by Dr. Shaw, there is no indication that any clothing or other organic material was found in the chest wound. An irregular missile can carry debris into a wound and such debris was carried into the wound of the wrist. I would have expected that an undistorted high velocity missile striking the wrist would not have carried material into it. Mr. SPECTER. Was there any other characteristic which led and leads you to conclude that the wrist was not the initial point of impact of a single high velocity bullet? Dr. GREGORY. Yes. Based on our experience with high velocity missile wounds of the forearm produced by rifles of the deer hunting calibre, there is tremendous soft tissue destruction as well as bone fragmentation which not infrequently culminates in amputation of the part. I do not believe that the missile wound in Governor Connally's right forearm was produced by a missile of such magnitude at the time it struck him. It either had to be one of lower initial energy or a missile which had been partially expended elsewhere before it struck his wrist. Mr. SPECTER. Would that opinion apply if you assumed that the missile had initial velocity when leaving the muzzle of the weapon of 200 feet per second? Dr. GREGORY. That's not a very high velocity missile. Mr. SPECTER. Pardon me--2,000 feet per second. Dr. GREGORY. I should say that a missile at 2,000 feet per second that strikes the forearm is likely to blow it very nearly off, if it is a missile of any mass as well.
