Three West Bank buildings received a shooting threat and closed at 4:30 p.m. Thursday. The Carlson School of Management, Hanson Hall and the Hubert H. Humphrey Center canceled all activities after 3:45 p.m. as a precaution. Thursday morning postal workers discovered a note in a St. Paul post office warning of a 6:00 p.m. shooting in the three buildings, University spokesman Daniel Wolter said. âÄúIt was basically a notice that someone was going to do [the shooting],âÄù Wolter said. Post office workers alerted the St. Paul Police who then told University Police. 2,047 students were displaced from classes in the buildings, Wolter said. Lectures planned for Thursday night are being moved to other buildings. Lorna Schmidt, graduate student in school of public health and office staffer at the Humphrey Center, said people in her office found out by e-mail, and then a supervisor came around to make sure everybody received the notice. Philosophy sophomore Max Wiessner said a woman came in to his Hanson Hall philosophy class and said there had been a threat against the building and the class could decide whether to cancel. She came back a little while later and told the class to dismiss and leave, but said there was no reason to panic. The class moved outside and continued their lecture on Kant in the courtyard outside the building, Wiessner said. Keep checking mndaily.com for updates.
