32 Killed at Virginia Tech

As you all have surely heard by now, Cho Seung-Hui, 23, shot and killed scores of students at Virginia Tech yesterday morning. Seung-Hui was from South Korean and a student at the university. His motive still remains a mystery.
From the LA Times:
Police said Cho used two guns in the classroom building, where the bulk of the killings occurred. Authorities said they found two handguns, a 9 mm and a .22-caliber, in the classroom where Cho’s body was found when the shooting ended.

Ballistic tests showed that one of the guns was also the one that was used to shoot and kill the two victims in the dormitory about two hours before the slaughter in Norris Hall, police said.
From the Washington Post:

Cho lived in Harper Hall, which according to a campus map is one building away from West Ambler Johnston. “The only thing we know about him is that he was a loner,” Larry Hincker, associate vice president of university relations said.
