I'm starting to wonder if Josh wasn't set up -- a la meet me here at X time for ___ for what I don't know -- but -- it's always been odd to me that he suddenly got up from that party and walked out. I'm sure there was a bathroom at the location of the party he was attending. Josh's Dad has always said he thought "someone grabbed Josh." Sounds like a good possibility. And whatever nastiness it was may have been covered up. Would that surprise anyone here?
The "set up and grabbed" theory is an interesting one. There are a few ways it could have gone down.
1) Crime of opportunity. Someone happens to be driving and spots Josh walking home alone. Possible, but looking at the route that Josh took home, the chances of this happening is so incredibly low.
2) A staged scenario. Someone faked needing help from someone and knew that Josh would be walking by. Josh falls for the ploy, and is grabbed and taken away. This scenario would take some time setting up because they would have no idea what time Josh would be walking by. Other witnesses would have surly seen a car or someone just waiting at the scene. Granted that one witness had come forward about a white SUV that was parked on the bridge for awhile that night, I still don't put too much stock in this one.
3) Josh was followed, and grabbed at the right moment. I believe this scenario is the one that Brian believes in the most. Someone was watching Josh's every move, fully intending to take him at the most opportune time. Out of the three scenarios here, I could see this one a little more likely to happen than the others.
What other possibilities could have happened?
