I heard three shots coming from the vicinity of where the President’s car was. I raced across the street. The Presidential car and other cars were turning onto Stemmons Fwy. Some of the bystanders said the shots came from the overpass. I ran across the street (Elm) and up the embankment over the retaining wall and into the freight yard and was unable to locate anything.

Mr. BOONE. The motorcade had already passed by us and turned back to the North on Houston Street. And we heard what we thought to be a shot. And there seemed to be a pause between the first shot and the second shot and third shots—a little longer pause. And we raced across the street there.
Mr. BALL. You raced across what street?
Mr. BOONE. Houston Street.
Mr. BALL. You turned to your right and went west?
Mr. BOONE. Well, there is a big cement works out there. We went on west across Houston Street, and then cut across the grass out there behind the large cement works there. Some of the bystanders over there seemed to think the shots came from up over the railroad in the freight yards, from over the triple underpass.
