There is a reason that this is one of the top cold cases in the country. There is no evidence of anything. It is baffling.
I have had many theories, you can blow a hole in them all.
1. Foul play. The neighborhood is a little rough. Worse now than then. Jason seemed pretty streetwise. I remember seeing him go out and talk to some wanna-be gang bangers who were throwing rocks at houses. Just let them know it wasn't cool, they shook hands and walked off. Long before he went missing. Problem? Gang violence is messy. We would know. A sexual or revenge crime is more likely.
2. I do not know Jason's sexual orientation. He seemed heterosexual to me (my gaydar is lousy though), but if he were gay, his father would have never accepted it. I could see a runaway situation. Problem? I don't think he would have bothered to leave behind his paycheck, bank account, and cell phone, unless he had help.
3. Abducted and killed. Problem? He was tall, strong, and it was the middle of the day. There has been an ongoing sewer project in Omaha for years. I had a theory that he got stuffed in one of those pipes, but the construction was still to the North East at that time. It did eventually come through the neighborhood. We have a missing boy in Omaha right now. You just don't know.
My current theory is kind of far fetched. I think he came out of the closet, got in a fight with his father and left town. I think he ended up in the Seattle area, and when his mother discovered this, she divorced his father and moved up there. Out of disgrace, they have all kept it a secret. If this were true, then why the ceremony at Roberts Park earlier this month. You would think they would just let it die.
