Blacksburg, Va. — Classes will never be held again in Virginia Tech’s Norris Hall, the academic building where 30 faculty members and students were killed a week ago, Mark G. McNamee, the university’s provost and vice president for academic affairs, said at a news briefing this afternoon.

All other options for the building’s future remain on the table, he said, including reopening it in some form or tearing it down.

Norris Hall contains classrooms, offices, and research space. The university had previously announced that the building, which remains ringed by yellow crime-scene tape, would be closed for the rest of the semester. Classes that had met in Norris Hall have been relocated to various spaces across the campus. —Sara Hebel
