Mr. SPECTER. Where did you find that portion of the President's head? Mr. HILL. It was found in the street. It was turned in, I believe, by a medical student or somebody in Dallas. Mr. SPECTER. Did you have any difficulty maintaining your balance on the back of the car after you had come up on the top of it? Mr. HILL. Not until we turned off to enter the Parkland Hospital. Mr. SPECTER. Now, what action did you take specifically with respect to placing Mrs. Kennedy back in the rear seat? Mr. HILL. I simply just pushed and she moved--somewhat voluntarily--right back into the same seat she was in. The President--when she had attempted to get out onto the trunk of the car, his body apparently did not move too much, because when she got back into the car he was at that time, when I got on top of the car, face up in her lap. Mr. SPECTER. And that was after she was back in the rear seat? Mr. HILL. Yes, sir. Mr. SPECTER. And where were the President's legs at that time? Mr. HILL. Inside the car. Mr. SPECTER. Now, what, if anything, did you observe as to the condition of Governor Connally at that time? Mr. HILL. After going under this underpass, I looked forward to the jump seats, where Mrs. Connally and Governor Connally were sitting. Mrs. Connally had been leaning over her husband. And I had no idea that he had been shot. And when she leaned back at one time, I noticed that his coat was unbuttoned, and that the lower portion of his abdomen was completely covered with blood. Mr. SPECTER. When was it that you first observed that? Mr. HILL. Just after going under the underpass. Mr. SPECTER. Were you able to observe anything which was occurring on the overpass as the President's motorcade moved toward the overpass? Mr. HILL. From the time I got on the back of the Presidential limousine, I didn't really pay any attention to what was going on outside the automobile. Mr. SPECTER. Had you noticed the overpass prior to the time you got on the Presidential automobile? Mr. HILL. Yes; I had scanned it. Mr. SPECTER. And do you recollect what, if anything, you observed on the overpass at that time? Mr. HILL. There were some people there, but I also noticed there was a policeman there. Mr. SPECTER. Approximately how many people would you say were there? Mr. HILL. Very few, I would say--maybe five, six. Mr. SPECTER. And how were you able to identify that there was a policeman there? Mr. HILL. He was wearing the uniform--presumably a policeman. Mr. SPECTER. What color uniform was it? Mr. HILL. I think it was blue of some shade. Mr. SPECTER. Did you identify it at that time as being of the identical color which other Dallas policemen were wearing whom you had observed in the area? Mr. HILL. That's correct, sir. Mr. SPECTER. Can you characterize the type of acceleration which the car made after it started to speed forward--that is, the Presidential car.
