Delaware State University canceled classes today after an early-morning shooting on the Dover campus left two students wounded and a suspect still at large, according to an announcement on the university’s Web site. The bulletin directed students to remain in their dormitories “until further notice” and told nonessential employees not to come to work. Details of the shooting were sketchy, but according to the alert, the gunman was a man and the victims were a male student and a female student. Colleges and universities have been treating all such incidents very seriously since a shooting rampage by a deranged student last spring at Virginia Tech took 33 lives. Virginia Tech was subsequently accused of not acting promptly after the first deaths to prevent a greater loss of life. —Andrew Mytelka
