9:50 a.m.

Using a shotgun, police shoot open the ordinary key lock of a fourth entrance to Norris Hall that goes to a machine shop and that could not be chained. The police hear gunshots as they enter the building. They immediately follow the sounds to the second floor.

Triage and rescue of victims begin.

A second email is sent by the administration to all Virginia Tech email addresses announcing that “A gunman is loose on campus. Stay in buildings until further notice. Stay away from all windows.” Loudspeakers broadcast a similar message.

Virginia Tech and Blacksburg police ERTs arrive at Norris Hall, including one paramedic with each team.
