This might be way out in left field, but I'm having a hard time coming up with likely scenarios that haven't already been mentioned. Is it possible that on his way back to his dorm he met up with some people from the Sartell/St. Cloud area on their way home for the weekend and decided to catch a ride with them instead of waiting a few more hours to ride with his friends? He might have thought it would be better to stay awake then and sleep when he got home than to sleep for a couple of hours, get up hungover to go home and then sleep again. If he was extremely drunk (or whatever), he may have said or done something that really set one, or some, of them off - like getting carsick? If they were taking I-94 home, the exit where Larry's is may have just been the first one they could take once things got hot. It's also possible that they were also in the same, or similar, condition as he was, which could make things escalate very quickly. All this talk about how safe Fargo/Moorehead usually is, and knowing what the St. Cloud area can be like, has just had me thinking along this line more. I'm not seeing his friends doing it, but there are probably several students out there that he went to high school with who aren't necessarily friends. Just a thought.
