Cho Byung-je, head of the North American affairs bureau of South Korea's foreign ministry, speaks at a news conference in Seoul April 17, 2007, after it was reported that the gunman who killed 32 people and then himself at Virginia Tech university on Monday was identified by police as Cho Seung-Hui, a South Korean studying at the university. Police said Cho was 23 and was studying English literature. They gave no motive for the shooting rampage, the worst in U.S. history. (Reuters)
