Shooter Lived in Dormitory, Va. Tech President Says

President Charles Steger Said There Was Possibly More Than One Shooter Involved

April 17, 2007 — - So many questions need to be answered about the shootings at Virginia Tech that killed 32 people.

Could the tragic massacre have been prevented? Did police wait too long to act? Were they aggressive enough? And why were students in the dark for so long?

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.

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.
