In Blacksburg, Virginia, people flocked to the main lawn at Virginia Tech, some clutching single roses, to remember the victims of the worst mass shooting in modern U.S. history. It was a year ago today that the horrific massacre at Virginia Tech happened, in which 32 students and professors were killed by a student gunman who then killed himself as police closed in.I encourage you today to remember the lives that were lost during this tragedy and continue to keep the Virginia Tech community in your thoughts.
