Because trucks backfire and various occurrences.
Mr. Ball. And you had heard noises originating from the Texas School Depository when they were building there?
Mr. Bowers. They were renovating. I—did carpenter work as well as sandblasted the outside of the building.
Mr. Ball. Now, were there any people standing on the high side—high ground between your tower and where Elm Street goes down under the underpass toward the mouth of the underpass?
Mr. Bowers. Directly in line, towards the mouth of the underpass, there were two men. One man, middle-aged, or slightly older, fairly heavy-set, in a white shirt, fairly dark trousers. Another younger man, about midtwenties, in either a plaid shirt or plaid coat or jacket.
Mr. Ball. Were they standing together or standing separately?
Mr. Bowers. They were standing within 10 or 15 feet of each other, and gave no appearance of being together, as far as I knew.
Mr. Ball. In what direction were they facing?
Mr. Bowers. They were facing and looking up towards Main and Houston, and following the caravan as it came down.
Mr. Ball. Did you see anyone standing on the triple underpass?
