Va. Tech students alerted after campus killing

BLACKSBURG, Va. (AP) - January 21, 2009 Students were warned Wednesday night to stay in place in an alert sent by e-mail and text message. After a suspect was taken into custody, students were told about an hour later they could resume normal activity.

The killing took place at the Graduate Life Center. A University news release says the suspect is a male graduate student and the victim is a female graduate student. Police found a knife they believe was the murder weapon.

The alert system was revamped after gunman Seung-Hui Cho took 32 lives before turning the gun on himself in an April 2007 rampage. The alert system has been used before.
