Another employee of the Union Terminal Co., Lee E. Bowers, Jr., was at work in a railroad tower about 14 feet above the tracks to the north of the railroad bridge and northwest of the corner of Elm and Houston, approximately 50 yards from the back of the Depository.[C3-70] (See Commission Exhibit No. 2218, p. 73.) From the tower he could view people moving in the railroad yards and at the rear of the Depository. According to Bowers, “Since approximately 10 o’clock in the morning traffic had been cut off into the area so that anyone moving around could actually be observed.”[C3-71] During the 20 minutes prior to the arrival of the motorcade, Bowers noticed three automobiles which entered his immediate area; two left without discharging any passengers and the third was apparently on its way out when last observed by Bowers.[C3-72] Bowers observed only three or four people in the general area, as well as a few bystanders on the railroad bridge over the Triple Underpass.[C3-73] As the motorcade proceeded toward the Triple Underpass, the spectators were clustered together along the east concrete wall of the railroad bridge facing the oncoming procession.[C3-74] (See Commission Exhibit No. 2215, p. 75.) Patrolman Foster stood immediately behind them and could observe all of them.[C3-75] Secret Service agents in the lead car of the motorcade observed the bystanders and the police officer on the bridge.[C3-76] Special Agent Winston G. Lawson motioned through the windshield in an unsuccessful attempt to instruct Patrolman Foster to move the people away from their position directly over the path of the motorcade.[C3-77] Some distance away, on the Stemmons Freeway overpass above Elm Street, Patrolman Murphy also had the group on the railroad bridge within view.[C3-78] When he heard the shots, Foster rushed to the wall of the railroad bridge over the Triple Underpass and looked toward the street.[C3-79] After the third shot, Foster ran toward the Depository and shortly thereafter informed Inspector Herbert J. Sawyer of the Dallas Police Department that he thought the shots came from the vicinity of Elm and Houston.[C3-80] [Illustration: COMMISSION EXHIBIT NO. 2118 VIEW FROM NORTH TOWER OF UNION TERMINAL COMPANY, DALLAS, TEXAS] [Illustration: COMMISSION EXHIBIT NO. 2214 VIEW FROM TRIPLE UNDERPASS, DALLAS, TEXAS] [Illustration: COMMISSION EXHIBIT NO. 2215 VIEW OF TRIPLE UNDERPASS FROM LOCATION ON ELM STREET (BETWEEN ZAPRUDER FRAMES 272-280)]
