Two Shot And Killed Near Virginia Tech Campus

The campus of Virginia Tech in Roanoke, Va. was on lockdown Thursday after a gunman killed a police officer during a traffic stop, and one other person. Campus officials instructed everyone to stay in a secure place indoors and barred visitors while police continued their search for the shooter. Virginia Tech established a number of security and emergency response measures after the 2007 mass shooting that killed 33 people.
