Hi Robin:
Might the running man with what appears to be a camera bag be Abraham Zapruder? Immediately prior to him being seen in Tina Towner's film, a woman in light-colored clothing moves quickly across the front of the arcade, from left to right. Might she have been Marilyn Sitzman, who was wearing such light-colored clothes? I tried to retrace Zapruder's movements away from the area some years ago, and at that time I noticed the two figures referenced above, but was never able to confirm or refute my hypothesis. The time frame of this Towner clip (a few minutes after the shooting) is not inconsistent with their movements after the shooting, and their direction of travel would also be consistent with their return to the Dal-Tex Building. I know it could potentially be true of any number of people, but ...
Any thought, anyone?
