Mrs. HILL. Well, evidently I didn't because the only conscious recollection I have of that--I mean--until all this other came out--I had always thought that they came from the knoll. Mr. SPECTER. Did you have any conscious impression of where the second shot came from? Mrs. HILL. No. Mr. SPECTER. Any conscious impression of where this third shot came from? Mrs. HILL. Not any different from any of them. I thought it was just people shooting from the knoll--I did think there was more than one person shooting. Mr. SPECTER. You did think there was more than one person shooting? Mrs. HILL. Yes, sir. Mr. SPECTER. What made you think that? Mrs. HILL. The way the gun report sounded and the difference in the way they were fired--the timing. Mr. SPECTER. What was your impression as to the source of the second group of shots which you have described as the fourth, perhaps the fifth, and perhaps the sixth shot? Mrs. HILL. Well, nothing, except that I thought that they were fired by someone else. Mr. SPECTER. And did you have any idea where they were coming from? Mrs. HILL. No; as I said, I thought they were coming from the general direction of that knoll. Mr. SPECTER. Well, did you think that the Secret Service was firing them from that knoll? Mrs. HILL. I said I didn't know--I really don't. Mr. SPECTER. You just had the general impression that shots were coming from the knoll? Mrs. HILL. Yes. Mr. SPECTER. And you had the general impression that the Secret Service was firing the second group of shots at the man who fired the first group of shots? Mrs. HILL. That's right. Mr. SPECTER. But you had no specific impression as to the source of those shots? Mrs. HILL. No. Mr. SPECTER. Did you get a very good look at that man, who you say was starting to run?
