So we still know nothing about this guy. Here is my take.

If this Daily Mail account is to be believed, the guy was Chinese:

Chinese carjack victim of Boston bombers only escaped when they stopped for Red Bull... and they didn't kill him because he 'wasn't American'

Again, when did any terrorist give a whit about what nationality anyone is, especially those they placed the bombs next to. Remember one of those killed was a Chinese grad student.

China has its own Muslim terrorist problem and that does not absolve this guy from being involved because he is a Chinese national.
