Mr. Dulles. But do you agree in general, taking the two wounds with which you are particularly familiar, that that would have been the trajectory as between the wrist and the thigh as drawn on that chart?
Dr. Gregory. Yes, essentially so; yes, sir.
Mr. Specter. For the record, how was that chart identified. Doctor?
Dr. Gregory. This is identified as Commission Exhibit 689.
Mr. Specter. Would you outline briefly the operative procedures which you performed on the Governor, please?
Dr. Gregory. Yes. The wound on the dorsum of the Governor's wrist was treated by debridement, which means to remove by sharp surgical excision all contaminated tissues and those which are presumed to have been rendered nonviable by force. This meant removing a certain amount of skin, subcutaneous tissue, fat, and all of the particles of clothing, threads of cloth, which we could identify; and, incidentally, a bit of metal or two.
That wound was subsequently left open; in other words, we did not suture it or sew it together. This is done in deference to potential infection which we know often to be associated with retained organic material such as cloth.
The wound on the volar surface or the palmar side of his wrist was enlarged. The purpose in enlarging it was an uncertainty as to the condition of the major nerves in the volar side of the wrist, and so these nerves were identified and explored and found to be intact, as were adjacent tendons. So that that wound was then sutured, closed.
After this, the fracture was manipulated into a hopefully respectable position of the fragments, and a cast was applied, and some traction, using rubber bands, was applied to the finger and the thumb in order to better hold the fracture fragments in their reduced or repositioned state.
Mr. Specter. Dr. Gregory, could all of the rounds which were inflicted on the Governor, that is, those described by Dr. Shaw, and those which you have described during your testimony, have been inflicted from one missile if that missile were a 6.5 millimeter bullet fired from a weapon having a muzzle velocity of approximately 2,000 feet per second at a distance of approximately 160 to 250 feet, if you assumed a trajectory with an angle of decline approximately 45 degrees?
