In evaluating the significance of these fingerprint and palmprint identifications, the Commission considered the possibility that Oswald handled these cartons as part of his normal duties. Since other identifiable prints were developed on the cartons, the Commission requested that they be compared with the prints of the 12 warehouse employees who, like Oswald, might have handled the cartons. They were also compared with the prints of those law enforcement officials who might have handled the cartons. The results of this investigation are fully discussed in chapter VI, page 249. Although a person could handle a carton and not leave identifiable prints, none of these employees except Oswald left identifiable prints on the cartons.[C4-232] This finding, in addition to the freshness of one of the prints and the presence of Oswald’s prints on two of the four cartons and the paper bag led the Commission to attach some probative value to the fingerprint and palmprint identifications in reaching the conclusion that Oswald was at the window from which the shots were fired, although the prints do not establish the exact time he was there. [Illustration: COMMISSION EXHIBIT NO. 2707 SIXTH FLOOR, TEXAS SCHOOL BOOK DEPOSITORY DALLAS, TEXAS] Oswald’s Presence on Sixth Floor Approximately 35 Minutes Before the Assassination Additional testimony linking Oswald with the point from which the shots were fired was provided by the testimony of Charles Givens, who was the last known employee to see Oswald inside the building prior to the assassination. During the morning of November 22, Givens was working with the floor-laying crew in the southwest section of the sixth floor.[C4-233] At about 11:45 a.m. the floor-laying crew used both elevators to come down from the sixth floor. The employees raced the elevators to the first floor.[C4-234] Givens saw Oswald standing at the gate on the fifth floor as the elevator went by.[C4-235] Givens testified that after reaching the first floor, “I discovered I left my cigarettes in my jacket pocket upstairs, and I took the elevator back upstairs to get my jacket with my cigarettes in it.”[C4-236] He saw Oswald, a clipboard in hand, walking from the southeast corner of the sixth floor toward the elevator.[C4-237] (See Commission Exhibit No. 2707, p. 142.) Givens said to Oswald, “Boy are you going downstairs? * * * It’s near lunch time.” Oswald said, “No, sir. When you get downstairs, close the gate to the elevator.”[C4-238] Oswald was referring to the west elevator which operates by pushbutton and only with the gate closed.[C4-239] Givens said, “Okay,” and rode down in the east elevator. When he reached the first floor, the west elevator--the one with the gate--was not there. Givens thought this was about 11:55 a.m.[C4-240] None of the Depository employees is known to have seen Oswald again until after the shooting.[C4-241]
