BLACKSBURG, Va. — An exploded cartridge from a nail gun produced sounds similar to gunfire near a Virginia Tech dormitory on Thursday, triggering the first use of the university’s revamped crisis alert system.
Virginia Tech added text messages and other ways of warning students of possible danger after gunman Seung- Hui Cho took 32 lives before killing himself last year.
The results were spotty: While an initial text message explaining police were investigating potential gunfire was successful, text messages that explained the sounds were not gunfire did not go through on mobile phones. The problem was traced to the service provider in the mountainous area, university spokesman Larry Hinckler said.
