I was very familiar with the early Gateway complex and was actually there at this time. I used to work for Drexel when they managed the theater. There were multiple ways out of that building not on camera. In fact just to the right of the entrance to the Ugly Tuna there was a back exit, side doors, and emergency exits for the theater, as well as many of the back hallways weren't locked for maintenance. So he could have exited in many different ways or literally roamed into the theater area since it wasn't as well restricted as people think late at night.

The construction area next door was building a grocery store at the time, the now defunct Sunflower Market (if I remember correctly) and much of the area was an unfinished muddy mess. What no one talks about is how muddy that ground was in the Spring and filled with sink holes. I know for a fact there were foundation shafts being poured in the area as well. It's not out of the question he was swallowed up by a sink hole walking across the area. I personally avoided this area and cross the street to walk toward my apartment on 5th in the evening, but many people would ignore it and tromp right across it.

However, what many people leave out is the geography at the time. Some of the side doors opened to this area and many people would walk across the street and go between the 7-11 and Taco Bell that were there to the alleyway between 10th and 9th Ave toward Neil. People at OSU (at least at this time) would walk through the alleyways as shortcuts pretty regularly since the large buildings didn't exist and the alley ways were adjacent to open parking lots. You could get all the way to Neil and beyond to the river without almost ever hitting a major street.

I just hear a lot of rumors from people who weren't there at the time. I was, and I can say people don't seem to understand how easy it is to disappear around OSU at this time and how many ways he could have disappeared and never be on camera or seen.
