Members of the Virginia Tech Corps of Cadets stand guard for 32 minutes following the lighting of a ceremonial candle at midnight on the Virginia Tech campus Monday in Blacksburg, Va. The candle remained lit for the duration of the day and was guarded again by cadets for 32 minutes prior to removal at midnight. Each anniversary since the April 2007 massacre on the Virginia Tech campus, classes have been suspended for the day in memory of the 32 students and faculty killed in the rampage by a lone gunman who then killed himself. On Monday, the fifth anniversary of the deadliest mass shooting in modern U.S. history, the 28,000 students on campus headed to class to honor the 32 who died. (The Associated Press)
