Do you take 100 rounds or more to take out your girlfriend? Hell, if she's your girlfriend, you know her class schedule and which room she'd be in.
No, he went there to kill as many people as possible, and not one witness said that he said or asked a thing.
particularly if you are soooo obsessed with her...
I have to wonder if maybe all or part of the reason more information is not coming out is that they think someone (quite possibly still on campus) may have helped him hide during the 2 hour period between shootings, and they are still trying to figure out where he was and what he did in that two hour period.
Another possibility for delaying information could be fear of reprisals, depending on who he is.
As you say, this certainly does not seem like his intent was simply to take out the girlfriend.
Well, if it’s his “ex-girlfriend” he might not know which classroom. Hey, I don’t think I knew which classes my now-wife was in every minute of the day (we both are Va. Tech graduates BTW, and she was in the college of Civil engineering, and it’s quite likely we both took classes in the rooms where the shootings took place).
But he wouldn’t have to ask questions — because he would know what his girlfriend looked like.
My initial RAMPANT SPECULATION was I’m sure wrong, but would make a good TV movie I think. Guy shows up in the dorm and finds his girl in bed with the RA. He threatens her, they get in a shouting match, at some point she says “don’t blame the RA, you are so unsatisfying that I’ve been sleeping with all the guys in my French Class”. He goes into a rage, shoots them both, and then heads to the french class to kill all the other “men” she’s been with.
