Jean Hill was born in 1931. She worked as a teacher in Oklahoma City before moving to a Dallas school in 1962. On 22nd November, 1963, Hill, watched the motorcade of President John F. Kennedy from the grassy knoll facing the Texas School Depository Building. Hill and her friend, Mary Moorman, who was taking Polaroid pictures of the motorcade, were only a few feet away from President John F. Kennedy when he was shot. Hill and Moorman thought the shots had come from behind her on the grassy knoll and as soon as the firing stopped they ran towards the wooden fence in an attempt to find the gunman. However, they were detained by two secret service men. After searching the two women they confiscated the picture of the assassination.
Hill gave a statement to the police where she stated: "Mary Moorman started to take a picture. We were looking at the president and Jackie in the back seat... Just as the president looked up two shots rang out and I saw the president grab his chest and fell forward across Jackie's lap... There was an instant pause between two shots and the motorcade seemingly halted for an instant. Three or four more shots rang out and the motorcade sped away."
Shirley Martin telephoned Hill on 25th January, 1964. She told Martin that as soon as the firing stopped they ran towards the wooden fence in an attempt to find the gunman. However, they were detained by two secret service men. After searching the two women they confiscated the picture of the assassination. Hill told Martin that she was very scared as another witness, Warren Reynolds, had been shot in the head by an unknown assailant, the night before: "Mrs Hill told me that she and Miss Moorman had received many threatening phone calls urging them to keep quiet and when they reported these to the Dallas police, they received an official brush-off. Mrs. Hill said Miss Moorman would not talk to me as she was much more frightened and upset over the whole thing than Mrs. Hill was."
Hill later gave evidence to the Warren Commission that was highly controversial. She claimed that she heard between four and six shots. Hill was also convinced that some of the shots came the grassy knoll. In interviews on television after the assassination Hill said she saw "a little white dog" in the rear seat of the president's car. As there was no dog in the car, the reliability of Hill's witness statement was undermined. However, 25 years later, it was revealed that a small white stuffed animal was on the back seat of the car. A child had presented it to Jackie Kennedy at the beginning of the tour of Dallas. This information was suppressed in order to discredit Hill as a reliable witness.
Jean Hill told Mark Lane: "The FBI was here for days. They practically lived here. They just didn't like what I told them I saw and heard when the President was assassinated. She declined to permit a filmed interview, stating, for two years I have told the truth, but I have two children to support and I am a public school teacher. My principal said it would be best not to talk about the assassination, and I just can't go through it all again. I can't believe the Warren Report. I know it's all a lie, because I was there when it happened, but I can't talk about it anymore because I don't want the FBI here constantly and I want to continue to teach here. I hope you don't think I'm a coward, but I cannot talk about the case anymore."
For many years Hill refused to give interviews about the John Kennedy assassination. However, in 1990, Hill agreed to work as a technical adviser on Oliver Stone's motion picture, JFK. The following year she revealed what happened after the assassination: "They (Secret Service agents) took me to the Records Building and we went up to a room on the fourth floor. There were two guys sitting there on the other side of a table looking out a window that overlooked the killing zone, where you could see all of the goings on. You got the impression that they had been sitting there for a long time. They asked me what I had seen, and it became clear that they knew what I had seen. They asked me how many shots I had heard and I told them four to six. And they said, No, you didn't. There were three shots. We have three bullets and that's all we're going to commit to now. I said, Well, I know what I heard, and they told me, What you heard were echoes. You would be very wise to keep your mouth shut. Well, I guess I've never been that wise. I know the difference between firecrackers, echoes, and gunshots. I'm the daughter of a game ranger, and my father took me shooting all my life." In 1992 Hill published her book on the case, JFK: The Last Dissenting Witness.
Jean Hill, who worked as a schoolteacher in Dallas for over twenty years, died on 7th November, 2000.
