A 23-year-old senior English major from Centreville was the gunman who killed 32 people and then himself on the Virginia Tech campus yesterday, university and law enforcement officials said.

Cho Seung Hui was a South Korean native who immigrated to this country as a child, officials said. His lifeless body was found in Norris Hall, a classroom building, among those of several other slain students, Virginia state police superintendent Col. Steve Flaherty said. He had apparently taken his own life.
