BLACKSBURG, Va. (AP) – The gunman suspected of carrying out the Virginia Tech massacre that left 33 people dead was identified today as an English major whose creative writing was so disturbing that he was referred to the school’s counseling service.

Cho Seung-Hui, a 23-year-old senior, arrived in the United States as boy from South Korea in 1992 and was raised in suburban Washington, D.C., officials said. He was living on campus in a different dorm from the one where yesterday’s bloodbath began.

Police and university officials still offered no clues to his motive in the massacre.

Professor Carolyn Rude, chairwoman of the university’s English department, said she did not personally know the gunman. But she said she spoke with Lucinda Roy, the department’s director of creative writing, who had Cho in one of her classes and described him as “troubled.”

“There was some concern about him,” Rude said. “Sometimes, in creative writing, people reveal things and you never know if it’s creative or if they’re describing things, if they’re imagining things or just how real it might be. But we’re all alert to not ignore things like this.”

She said Cho was referred to the counseling service, but she said she did not know when, or what the outcome was. Rude refused to release any of his writings or his grades, citing privacy laws.
