It’s good the information is reaching the hiking community but he was not a hiker. He started his journey in jeans.
Like others have mentioned the key to figuring out who he is, is getting the story into his circle of life.
I always feel like everyone knows about all these cases because they seem to be all over the media. But I am interested in them so I click on them, I read them, I look for more information. I’ve mentioned missing persons cases time and time again and no one ever knows anything about the case.
In one case that I followed I ended up working in the criminal justice system shortly after the kidnapper was sent to prison. I mentioned it at work and only or person was familiar with the case and new far less details than I did, he was one of the investigators.
So just because there are hundreds on websleuths and Reddit and Facebook interested in solving this case, it’s unlikely that anyone who know him has heard of it.
