Okay, so I work in downtown Pittsburgh. Yesterday afternoon I walked the exact route I assume he would have taken (minus the Katz Plaza cut through). I saw the river rescue divers from the Roberto Clemente Bridge (6th Street Bridge). Some observations:
- The railings on the bridge come up to almost my shoulder, and I am 5'9". I do not believe there would be any way to fall off of the bridge unless you had climbed it somehow or someone pushed you over.
- There is a barrier between you and cars on the bridge, so he most likely wasn't hit from behind and thrown over the bridge from the impact.
- Neither the Pittsburgh or the North Side of the bridge are anywhere close to the water. You would need to deliberately go down to the edge.
- There are a ton of cameras after you leave the bridge and walk past PNC Park. Bars would still be open at this time - at least two.
- After you pass the bars, things get a little deserted and scary. You have to pass under an overpass as well as a train trestle.
- After you make it to the post office, there is a raised area about ten feet high on the right. You can climb some scary nailed wooden planks to get up there (I did). It looks like a hobo garden but it didn't look recently inhabited and I didn't see anyone up there. However, I did see a dark coat that looked new-ish. There are a bunch of sheltered areas up there. Very creepy. Has this area been searched?
- Five minutes later, you would be in the Parkview apartment area, where I saw more cameras.
What was the state of his apartment? Had he definitively not made it home that night? Is it possible he got home and went out again?
Do we know for sure his car wasn't in the Katz parking garage?
