Mr. SPECTER. Who made that radio communication? Mr. GREER. Kellerman. Mr. SPECTER. Tell us as precisely as you can when he made that radio communication. Mr. GREER. After he had said to me, "Get out of here fast." He got the radio and called to the lead car, "Get us to a hospital fast, nearest hospital fast." Mr. SPECTER. Do you recall whether he said anything else at that time? Mr. GREER. After he had said to me, he said, "12:30," and that is all I remember him saying to me was 12:30, and he had communications with the cars but I don't remember what he had said to them. Mr. SPECTER. Did he say just "12:30," or was it 12:30 used in a sentence? Mr. GREER. He said "12:30." He looked at his watch, he said "12:30," and we were in the underpass at the time. Mr. SPECTER. Mr. Greer, would you on Commission's Exhibit 347, mark with an "A" as best you can indicate the position of the President's automobile at the time of the first shot? Mr. GREER. Do you want me to mark it on this exhibit? Mr. SPECTER. Right there, that is right, that red pencil with an "A," a small "A." Mr. GREER. This is the center, I would say [indicating]. Mr. SPECTER. Will you mark your best estimate as to the position of the automobile at the time of the second shot with the letter "B"? Mr. GREER. I would have to guess how far I had traveled at that time. I really wouldn't know. It was probably a little farther, only guessing how far I would go. I am guessing as to the distance between them. Maybe farther but I am only guessing to say at that. I wouldn't have any definite reason. Mr. SPECTER. Would you make that "B" a little plainer, if you can? Mr. GREER. Yes. Mr. SPECTER. Could you give us the best estimate in feet as to the distance you traveled from the time of the first shot to the time of the second shot? Mr. GREER. No, sir; I don't believe I could. Anything I would say would be guessing. Mr. SPECTER. Would you be able to give us a meaningful mark on the overhead photograph as to the position of your car at the time of the third shot? Mr. GREER. From this overhead. I probably was where this mark is here. Mr. SPECTER. Would you mark it? Mr. GREER. I will put it alongside. Mr. SPECTER. Put a little "C." Mr. GREER. This was for the third shot. Mr. SPECTER. Yes, sir. Mr. GREER. This is "C." This not having an idea really of how much footage is in there at all. I wouldn't---- The CHAIRMAN. I didn't understand. Mr. GREER. I said I wouldn't probably know, Mr. Chief Justice, how many feet would be in that distance, I would be guessing how many feet. The CHAIRMAN. Yes; I understand. Mr. SPECTER. Did you have any opportunity to observe the overhead as you were driving along after the last shot occurred? Mr. GREER. No, sir. I was fairly close to it, to the best of my memory, and I was trying to watch then where I was going. I had to look ahead to see, I was catching up on the lead car real fast, and I had to watch what was ahead of me.
