On April 16th, 2007, the deadliest school shooting in U.S. history occurred at Virginia Tech.
The shooter took the lives of 32 people before he turned the gun on himself.
Kristina Anderson was shot three times when she arrived for her French class, and has used that experience to educate others.
Anderson shared the details of that tragic day in American history with emergency responders in Texoma, and said she hopes her experience can help emergency responders prepare for incidents involving active shooters.
