A law enforcement official says the gunman who fled after killing a police officer on the Virginia Tech campus is believed to be dead.
After the officer was shot today, authorities found a second body in a campus parking lot.
It's not clear if that second body was that of the gunman.
The shooting triggered a lockdown on the sprawling campus that in 2007 was the scene of the deadliest mass shooting in U.S. history.
School officials are now telling students and staff that there is no longer any danger.
