Mr. Hubert. Would you describe what you saw or heard, please, sir?
Mr. Cabell. I heard the shot. Mrs. Cabell said, "Oh a gun" or "a shot", and I was about to deny and say "Oh it must have been a firecracker" when the second and the third shots rang out. There was a longer pause between the first and second shots than there was between the second and third shots. They were in rather rapid succession. There was no mistaking in my mind after that, that they were shots from a high-powered rifle.
Mr. Hubert. Are you familiar with rifles so that your statement that it was your opinion it came from a high-powered rifle was that of a person who knows something about it?
Mr. Cabell. I have done a great deal of hunting and also used military shoulder guns, as well as hunting rifles.
Mr. Hubert. Were you in the armed services during the war?
Mr. Cabell. No; I was not, but there was no question in my mind as to their being from a high-powered rifle and coming from the direction of the building known as the School Book Depository.
Mr. Hubert. That you judged, I suppose, by the direction from which you thought the sound came?
Mr. Cabell. Right.
Mr. Hubert. Could you estimate the number of seconds, say, between the first and second shots, as related to the number of seconds between the second and third shots? Perhaps doing it on the basis of a ratio?
Mr. Cabell. Well, I would put it this way. That approximately 10 seconds, elapsed between the first and second shots, with not more than 5 seconds having elapsed until the third one.
