Well the article states he talked friends out of drugs. Kind of gives you a sense of his values. He left his GF's home and was wearing slippers if I recall from an article. So anything he did afterwards was on a whim. Sounds like he had direction in a career. They say the matsu career and technical isn't necessarily easy to get into. I myself was an aircraft mechanic and being that he was in that direction, i am sure he was a hard worker. I believe he met an unfortunate circumstance or met evil. And I pray if it was evil, he is released back unto his loved ones. 

I'm not so quick to point fingers at the victim. Even if he was a "bad" kid, his life is no less precious. That's someone's baby. I know I would never stop looking for my son...if he turns out to be an upstanding citizen or not.
