It is odd. I thought at first he was a runaway but the police don’t seem to have ever thought this? I think I assumed he was unhappy and running away (taking money, single ticket etc) but really that poor child appears to have been tricked into a terrible outcome.
I agree, this is what I've always thought, but such a mystery as to how? As he didn't seem to have been in contact with anybody. No 'net access, no 'phone etc.
There's a good subreddit about him. I often wonder if It's in poor taste to discuss someone's tragedies like this but then I feel no, It's more important to keep people interested and concerned.
And yes, just HOW did these men end up with images of him (do we have a source for that? I'll google).
