Authorities at Virginia Tech College issued a lock down notice this morning after a suspect was seen carrying a weapon on campus.
In April 2007, a gunman shot and killed 32 people before shooting himself in the worst school shooting in U.S. history.
Shortly after 9am this morning three kids attending a summer camp reported seeing a white male, six foot tall, with light brown hair, outside college dorms carrying what may have been a handgun.
