Mr. SPECTER. As to the wound on the back of Governor Connally, was there any indication that the bullet was tumbling prior to the time it struck him? Dr. SHAW. I would only have to say that I'm not a ballistics expert, but the wound on his chest was not a single puncture wound, it was long enough so that there might have been some tumbling. Mr. SPECTER. You mean the wound on his back? Dr. SHAW. The wound on his back--yes, it was long enough so that there might have been some tumbling. In other words, it was not a spherical puncture wound. Mr. SPECTER. So it might have had some tumbling involved, or it might not have? Dr. SHAW. Yes; I don't know whether the clothes would have occasioned this or not. Mr. SPECTER. My question would be that perhaps some tumbling might have been involved as a result of decrease in velocity as the bullet passed through President Kennedy, whether there was any indication from the surface of the wound which would indicate tumbling. Dr. SHAW. The wound entrance was an elliptical wound. In other words, it had a long diameter and a short diameter. It didn't have the appearance of a wound caused by a high velocity bullet that had not struck anything else; in other words, a puncture wound. Now, you have to also take into consideration, however, whether the bullet enters at a right angle or at a tangent. If it enters at a tangent there will be some length to the wound of entrance. Mr. SPECTER. So, would you say in net that there could have been some tumbling occasioned by having it pass through another body or perhaps the oblique character of entry might have been occasioned by the angle of entry. Dr. SHAW. Yes; either would have explained a wound of entry. Mr. SPECTER. Fine, thank you very much, Doctor. Dr. SHAW. Thank you. TESTIMONY OF DR. CHARLES FRANCIS GREGORY The testimony of Dr. Charles Francis Gregory was taken at 2:30 p.m., on March 23, 1964, at Parkland Memorial Hospital, Dallas, Tex., by Mr. Arlen Specter, assistant counsel of the President's Commission.
