Other witnesses on the railroad bridge had varying views concerning the source and number of the shots. Austin L. Miller, employed by the Texas-Louisiana Freight Bureau, heard three shots and thought that they came from the area of the Presidential limousine itself.[C3-81] One of his coworkers, Royce G. Skelton, thought he heard four shots, but could not tell their exact source.[C3-82] Frank E. Reilly, an electrician at Union Terminal, heard three shots which seemed to come from the trees “On the north side of Elm Street at the corner up there.”[C3-83] According to S.M. Holland, there were four shots which sounded as though they came from the trees on the north side of Elm Street where he saw a puff of smoke.[C3-84] Thomas J. Murphy, a mail foreman at Union Terminal Co., heard two shots and said that they came from a spot just west of the Depository.[C3-85] In the railroad tower, Bowers heard three shots, which sounded as though they came either from the Depository Building or near the mouth of the Triple Underpass. Prior to November 22, 1963, Bowers had noted the similarity of the sounds coming from the vicinity of the Depository and those from the Triple Underpass, which he attributed to “a reverberation which takes place from either location.”[C3-86] Immediately after the shots were fired, neither the policemen nor the spectators on the railroad bridge over the Triple Underpass saw anything suspicious on the bridge in their vicinity. (See Commission Exhibit No. 2214, p. 74.) No one saw anyone with a rifle. As he ran around through the railroad yards to the Depository, Patrolman Foster saw no suspicious activity.[C3-87] The same was true of the other bystanders, many of whom made an effort after the shooting to observe any unusual activity. Holland, for example, immediately after the shots, ran off the overpass to see if there was anyone behind the picket fence on the north side of Elm Street, but he did not see anyone among the parked cars.[C3-88] Miller did not see anyone running across the railroad tracks or on the plaza west of the Depository.[C3-89] Bowers and others saw a motorcycle officer dismount hurriedly and come running up the incline on the north side of Elm Street.[C3-90] The motorcycle officer, Clyde A. Haygood, saw no one running from the railroad yards.[C3-91] THE PRESIDENTIAL AUTOMOBILE
