Bonnie Ray Williams, who was also working with the floor-laying crew, returned to the sixth floor at about noon to eat his lunch and watch the motorcade.[C6-51] He looked out on Elm Street from a position in the area of the third or fourth set of windows from the east wall.[C6-52] At this point he was approximately 20-30 feet away from the southeast corner window. He remained for about “5, 10, maybe 12 minutes” eating his lunch which consisted of chicken and a bottle of soda pop.[C6-53] Williams saw no one on the sixth floor during this period, although the stacks of books prevented his seeing the east side of the building.[C6-54] After finishing his lunch Williams took the elevator down because no one had joined him on the sixth floor to watch the motorcade.[C6-55] He stopped at the fifth floor where he joined Harold Norman and James Jarman, Jr., who watched the motorcade with him from a position on the fifth floor directly below the point from which the shots were fired. Williams left the remains of his lunch, including chicken bones and a bottle of soda, near the window where he was eating.[C6-56] Several witnesses outside the building claim to have seen a person in the southeast corner window of the sixth floor. As has already been indicated, some were able to offer better descriptions than others and one, Howard L. Brennan, made a positive identification of Oswald as being the person at the window.[C6-57] Although there are differences among these witnesses with regard to their ability to describe the person they saw, none of these witnesses testified to seeing more than one person in the window.[C6-58] One witness, however, offered testimony which, if accurate, would create the possibility of an accomplice at the window at the time of the assassination. The witness was 18-year-old Arnold Rowland, who testified in great detail concerning his activities and observations on November 22, 1963. He and his wife were awaiting the motorcade, standing on the east side of Houston Street between Maine and Elm,[C6-59] when he looked toward the Depository Building and noticed a man holding a rifle standing back from the southwest corner window on the sixth floor. The man was rather slender in proportion to his size and of light complexion with dark hair.[C6-60] Rowland said that his wife was looking elsewhere at the time and when they looked back to the window the man “was gone from our vision.”[C6-61] They thought the man was most likely someone protecting the President. After the assassination Rowland signed an affidavit in which he told of seeing this man, although Rowland was unable to identify him.[C6-62]
