Another person who saw the assassin as the shots were fired was Amos L. Euins, age 15, who was one of the first witnesses to alert the police to the Depository as the source of the shots, as has been discussed in chapter III.[C4-305] Euins, who was on the southwest corner of Elm and Houston Streets,[C4-306] testified that he could not describe the man he saw in the window. According to Euins, however, as the man lowered his head in order to aim the rifle down Elm Street, he appeared to have a white bald spot on his head.[C4-307] Shortly after the assassination, Euins signed an affidavit describing the man as “white,”[C4-308] but a radio reporter testified that Euins described the man to him as “colored.”[C4-309] In his Commission testimony, Euins stated that he could not ascertain the man’s race and that the statement in the affidavit was intended to refer only to the white spot on the man’s head and not to his race.[C4-310] A Secret Service agent who spoke to Euins approximately 20 to 30 minutes after the assassination confirmed that Euins could neither describe the man in the window nor indicate his race.[C4-311] Accordingly, Euins’ testimony is considered probative as to the source of the shots but is inconclusive as to the identity of the man in the window. In evaluating the evidence that Oswald was at the southeast corner window of the sixth floor at the time of the shooting, the Commission has considered the allegation that Oswald was photographed standing in front of the building when the shots were fired. The picture which gave rise to these allegations was taken by Associated Press Photographer James W. Altgens, who was standing on the south side of Elm Street between the Triple Underpass and the Depository Building.[C4-312] As the motorcade started its descent down Elm Street, Altgens snapped a picture of the Presidential limousine with the entrance to the Depository Building in the background.[C4-313] Just before snapping the picture Altgens heard a noise which sounded like the popping of a firecracker. Investigation has established that Altgens’ picture was taken approximately 2 seconds after the firing of the shot which entered the back of the President’s neck.[C4-314] [Illustration: COMMISSION EXHIBIT NO. 1061 TEXAS SCHOOL BOOK DEPOSITORY DIAGRAM OF FIRST FLOOR] In the background of this picture were several employees watching the parade from the steps of the Depository Building. One of these employees was alleged to resemble Lee Harvey Oswald.[C4-315] The Commission has determined that the employee was in fact Billy Nolan Lovelady, who identified himself in the picture.[C4-316] Standing alongside him were Buell Wesley Frazier[C4-317] and William Shelley,[C4-318] who also identified Lovelady. The Commission is satisfied that Oswald does not appear in this photograph. (See Commission Exhibit No. 900, p. 113.) Oswald’s Actions in Building After Assassination
