College and School Campuses Throughout the Country Have Received Several Threats

Since Monday's fatal shooting at Virginia Tech, there have been threats of similar attacks at school and college campuses throughout the United States. Thirty-three people were killed in the Virginia Tech massacre including the shooter, Seung-Hui Cho.

In a tape sent to NBC News, Cho expressed his admiration for Dylan Klebold and Eric Harris, the young men responsible for killing 12 students at Columbine High School in Colorado on April 20, 1999. Similarly Harris had expressed admiration for the April 19, 1995, bombings in Oklahoma City.
