Saw this linked on another thread. From timebomb, a resident of Norman who has info from a friend inside the LE says that Hinrichs had a ME roommate -- maybe it's a clue, maybe not.

One thing our local news (OKC) mentioned was that they couldn't find his roommate, but that he had nothing at all to do with the bombing. Hmmm....
Our local channel 9 (CBS) just reported that his roommate was a Pakistani. They, too, are saying he can't be found.
