I live in SoCal, but i doubt I'm gonna find the kid. I hear the last word is that he was in San Diego. If there's been no word, it probably means he made some friends, went in on some sort of crib with them, and is working an under the table job to make ends meet. If he feels like he can trust revealing himself and his location to parents, family, etc., I'm sure he'll do it. If he's not 18 yet, you'll probably just have to wait until then, as he won't feel as threatened then.
I'm not saying this is the case, I'm just saying that if I were in his shoes and had half a brain, that's exactly what I would've done.
