Same guns used in two Virginia Tech shootings

BLACKSBURG: The same gun was used in two shootings at Virginia Tech University, suggesting only one gunman killed 32 people and himself, Colonel Steve Flaherty, Superintendent of Virginia State Police, said on Tuesday.   

"The ballistics test says that one of the weapons used in Norris Hall was also used in the shooting," he said.    

"It certainly is reasonable for us to assume that Cho Seung-Hui was the shooter in both places but we don't have the evidence to take us there at this particular point in time," he said.

Thirty-three people, including Cho, died in two separate shootings more than two hours apart on Monday in the deadliest school shooting in US history.   

Flaherty could not exclude the possibility however that Cho had help carrying out the massacre.   

"But we are exploring whether or not there was someone that may or may not have helped Cho at any point during his planning or his execution of this particular event," he said.
