BLACKSBURG, Va. - A Virginia Tech spokesman says the gunman was "a loner." And he says officials are having difficulty finding information about him.
The shooter has been identified as 23-year-old Cho Seung-Hui, a senior from South Korea. He was an English major and lived in a dorm on campus. An official with Homeland Security says Cho was a permanent legal resident of the U.S.
Cho committed suicide after the attacks, the first at a dorm on campus, the second inside a classroom building. No word yet on a motive.
Law enforcement officials say his fingerprints were found on the guns used in both shootings. The serial numbers on the two weapons had been filed off.
One shooting victim said Cho fired away in silence with "no specific target - just taking out anybody he could."
Virginia Tech officials have canceled classes for the rest of the week following Monday's deadly shootings. The school's president says it's to give students a chance to mourn.
The school made the announcement as it confirmed the identification of the gunman who took his life after the second round of shootings, in a classroom building.
That building, where witnesses say students jumped from windows
to avoid gunfire, will be closed for the remainder of the semester.
