Virginia Tech Massacre Investigation

Virginia Tech President Charles Steger told "Good Morning America's" Diane Sawyer this morning that there was still the possibility that there were two shooters in the separate campus attacks on Monday morning.

Steger said that the shooter who took his own life in the Norris Hall classroom building, where 30 other people were also killed, was a student of Asian descent who lived in a dormitory at Virginia Tech.

The name of gunman has been released by the police as, "Seung Hui Cho." 23 year old from South Korea, permanent resident of U.S. since 1992 and a student at Virginia Tech.

Steger referred to this person as the "second shooter."

"It appears that the second shooter was a resident in a dormitory," Steger said. "We don't have all of that confirmed but it appears he was an on-campus resident."

Sawyer asked whether there was more than one shooter involved.

"We don't know for sure. That's what we're trying to confirm," Steger said.

Steger said police had questioned a person of interest in the case.

"They have questioned them once and they'll probably continue to question the individual," he said.
