Thought you may want to know the name of Hinrichs' roommate. According to this article the name is Fazal M. Cheema - Finance Major.
We also had a SoonerFan forum person post that they had seen a "young man" in handcuffs near the stadium when the poster left 3 minutes before halftime to go to his campus office. There were three cops with the "young man" who was handcuffed and they were pretty gruff with the Soonerfan, sort of saying to "move on." He just thought the guy (who was on the ground) was a drunk. Bet it was one of the guys from the party.
