S. M. Holland, a railroad signal supervisor standing on the triple underpass, told the Commission he heard four shots and saw “a puff of smoke came out about 6 or 8 feet above the ground right out from under those trees.” [1]
Lee Bowers, in a railroad tower behind the knoll, said he noticed two men near the fence before the shots: one middle-aged and heavy-set in a white shirt, one younger in a plaid shirt or jacket. They were 10 or 15 feet apart and did not seem to be together. He heard three shots and said they came either from the Depository or from near the mouth of the underpass; he could not tell which. [2]
At the time of the shots he saw “something out of the ordinary, a sort of milling around, but something occurred in this particular spot which was out of the ordinary, which attracted my eye for some reason, which I could not identify.” He told the Commission about three cars that drove into the closed parking area before noon. [2]
The House committee’s count of 178 witnesses found 21 who placed shots at the knoll. Holland and others ran to the fence afterward and found footprints and people but no gunman. [3]
