Authorities identify the gunman suspected of killing 32 people at Virginia Tech as 23-year-old Cho Seung-Hui, an English major who has lived in the United States since immigrating from South Korea in 1992. He had a Centreville, Virginia address and was a resident of VT's Harper Hall.
Police recovered two handguns, a nine millimeter and a 22 caliber. Police say ballistics tests shows that one of the guns found with Cho Seung-Hui was used at the shootings in Ambler Johnston Dormitory and Norris Hall.
Steve Flaherty, with the Virginia State Police said, "The evidence has not led us to say with all certainty that the same shooter was involved" in both places. However he said did not have evidence that there was another shooter.
