Arlen Specter: All right. What was the condition of the crowd as the motorcade made a right-hand turn off of Main Street onto Houston?
Clinton Hill: The crowd was very large on Main Street, and it was thinning down considerably when we reached the end of it, and turned right on Houston Street. Noticeably on my side of the car, which was the left-hand side of the street.
Arlen Specter: And what is your best estimate as to the speed of the President's car at the time it made the right-and turn onto Houston Street?
Clinton Hill: In the curve?
Arlen Specter: The speed - in the curve itself; yes.
Clinton Hill: We were running generally 12 to 15 miles per hour. I would say that in the curve we perhaps slowed to maybe 10 miles per hour.
Arlen Specter: And how far behind the President's car was the Presidential follow-up car as the turn was made onto Houston Street?
Clinton Hill: Four to five feet, at the most.
Arlen Specter: I show you a photograph of a building which has already been marked as Commission Exhibit No. 348, and ask you if at this time you can identify what that building is.
Clinton Hill: I believe I can, sir; yes.
Arlen Specter: And what building is it?
Clinton Hill: It is the Texas School Book Depository.
Arlen Specter: Now, does that building appear on the Commission Exhibit No. 354?
Clinton Hill: Yes, sir; it does.
Arlen Specter: Did you have any occasion to notice the Texas School Book Depository Building as you proceeded in a generally northerly direction on Houston Street?
Clinton Hill: Yes, sir. It was immediately in front of us and to our left.
Arlen Specter: Did you notice anything unusual about it?
Clinton Hill: Nothing more unusual than any other building along the way.
Arlen Specter: What is your general practice, if any, in observing such buildings along the route of a Presidential motorcade?
Clinton Hill: We scan the buildings and look specifically for open windows, for people hanging out, and there had been, on almost every building along the way, people hanging out, windows open.
Arlen Specter: And did you observe, as you recollect at this moment, any open windows in the Texas School Depository Building?
Clinton Hill: Yes, sir; there were.
Arlen Specter: Are you able to recollect specifically which windows were open at this time?
Clinton Hill: No, sir; I cannot.
Arlen Specter: What was the condition of the crowd along the streets, if any, along Elm Street, in front of the Texas School Book Depository Building?
Clinton Hill: On the left-hand side of the street, which is the side I was on, the crowd was very thin. And it was a general park area. There were people scattered throughout the entire park.
Arlen Specter: Now, what is your best estimate of the speed of the President's automobile as it turned left off of Houston onto Elm Street?
Clinton Hill: We were running still 12 to 15 miles per hour, but in the curve I believe we slowed down maybe to 10, maybe to 9.
Arlen Specter: How far back of the President's automobile was the Presidential car when the President's follow-up car had just straightened out on Elm Street?
Clinton Hill: Approximately 5 feet.
Arlen Specter: Now, as the motorcade proceeded at that point, tell us what happened.
Clinton Hill: Well, as we came out of the curve, and began to straighten up, I was viewing the area which looked to be a park. There were people scattered throughout the entire park. And I heard a noise from my right rear, which to me seemed to be a firecracker. I immediately looked to my right and, in so doing, my eyes had to cross the Presidential limousine and I saw President Kennedy grab at himself and lurch forward and to the left.
Arlen Specter: Why don't you just proceed, in narrative form, to tell us?
Thomas Boggs: This was the first shot?
Clinton Hill: This is the first sound that I heard; yes, sir. I jumped from the car, realizing that something was wrong, ran to the Presidential limousine. Just about as I reached it, there was another sound, which was different than the first sound. I think I described it in my statement as though someone was shooting a revolver into a hard object - it seemed to have some type of an echo. I put my right foot, I believe it was, on the left rear step of the automobile, and I had a hold of the handgrip with my hand, when the car lurched forward. I lost my footing and I had to run about three or four more steps before I could get back up in the car. Between the time I originally grabbed the handhold and until I was up on the car, Mrs. Kennedy - the second noise that I heard had removed a portion of the President's head, and he had slumped noticeably to his left. Mrs. Kennedy had jumped up from the seat and was, it appeared to me, reaching for something coming off the right rear bumper of the car, the right rear tail, when she noticed that I was trying to climb on the car. She turned toward me and I grabbed her and put her back in the back seat, crawled up on top of the back seat and lay there...
Arlen Specter: What is your best estimate of the speed of the President's car at the precise time of the first shot, Mr. Hill?
Clinton Hill: We were running between 12 to 15 miles per hour, but no faster than 15 miles per hour...
Arlen Specter: Now, what is your best estimate on the timespan between the first firecracker-type noise you heard and the second shot which you have described?
Clinton Hill: Approximately 5 seconds...
Arlen Specter: Did Mrs. Kennedy say anything as you were proceeding from the time of the shooting to Parkland Hospital?
Clinton Hill: At the time of the shooting, when I got into the rear of the car, she said, "My God, they have shot his head off." Between there and the hospital she just said, "Jack, Jack, what have they done to you," and sobbed.
Arlen Specter: What did you observe as to President Kennedy's condition on arrival at the hospital?
Clinton Hill: The right rear portion of his head was missing. It was lying in the rear seat of the car. His brain was exposed. There was blood and bits of brain all over the entire rear portion of the car. Mrs. Kennedy was completely covered with blood. There was so much blood you could not tell if there had been any other wound or not, except for the one large gaping wound in the right rear portion of the head.
Arlen Specter: Did you have any opportunity to observe the front part of his body, to see whether there was any tear or rip in the clothing on the front?
Clinton Hill: I saw him lying there in the back of the car, when I was immediately above him. I cannot recall noticing anything that was ripped in the forward portion of his body.
Arlen Specter: What action, if any, did you take to shield the President's body?
Clinton Hill: I kept myself above the President and Mrs. Kennedy on the trip to Parkland...
Arlen Specter: I believe you testified as to the impression you had as to the source of the first shot. To be sure that the record is complete, what was your reaction as to where the first shot came from, Mr. Hill?
Clinton Hill: Right rear.
Arlen Specter: And did you have a reaction or impression as to the source of point of origin of the second shot that you described?
Clinton Hill: It was right, but I cannot say for sure that it was rear, because when I mounted the car it was - it had a different sound, first of all, than the first sound that I heard. The second one had almost a double sound - as though you were standing against something metal and firing into it, and you hear both the sound of a gun going off and the sound of the cartridge hitting the metal place, which could have been caused probably by the hard surface of the head. But I am not sure that that is what caused it.
