i've known him since my freshman year of high school. he was the last person i expect to ever shoot up a high school. he was honestly incredibly humble and down to earth. he was a little geeky, but in a charming way. so i don't know anyone who hates him really. so it came as a surprise to me at least. >> did you have any indication in the last couple of days that there was anything going on with him, anything wrong with him? >> i heard from a few friends that -- and i believe it was the spanish class on wednesday -- that he showed a few outbursts that were fairly violent. >> do you know any more details on that? >> he went out to get water, i believe, or something from his locker. when he came back the door was locked so he started pounding on it and screaming and cursing at the teacher apparently. >> that was something which was unusual for him. >> right. >> how are you and the other students doing? it's one thing to see this kind
