Mr. Specter. The President's stand-in?
Mr. Shaneyfelt. Right. The angle to the rifle in the window was 40°10´.
Mr. Specter. And what is the other data?
Mr. Shaneyfelt. The distance to the overpass was 447 feet, and the angle to the overpass was minus O°27´; that is, 27´ below the horizontal.
Senator Cooper. May I ask a question there? How did you establish the location of the rifle in making those calculations?
Mr. Shaneyfelt. The location of the rifle was established on the basis of other testimony and information furnished to us by the Commission, photographs taken by the Dallas Police Department immediately after the assassination, and the known opening of the window.
It was an estimation of where the rifle most likely was based on the knowledge that the Commission has through testimony.
Mr. Specter. Senator Cooper, Mr. Frazier is present and has been sworn, and he is going to identify that. He could do it at this time, to pinpoint that issue.
Senator Cooper. I think we can just make a note of that, and go ahead with this witness.
Mr. Specter. Fine. We will proceed then with this witness and Mr. Frazier will testify in due course.
