After the Presidential car had turned the corner onto Elm Street, Mr. Ault heard three loud reports which Mr. Ault immediately recognized as shots from a high-powered rifle. He noted that the first and second shots sounded to him to be close together and the third shot was spaced more after the second shot, the first two shots sounding close enough to be from an automatic rifle. Mr. Ault could not tell from what direction the rifle shots came. Following the first shot Mr. Ault noted that President Kennedy appeared to raise up in his seat in the Presidential automobile and after the second shot the President slumped into his seat.
