It has been 17 years after two gunmen stormed Columbine High School, killing 12 students and a teacher and later turning the gun on themselves.
On the 17th anniversary of this national tragedy, we want to pay tribute to those who were killed on April 20, 1999.
The victims of that tragic shooting were:
Cassie Bernall. A born-again Christian who was active in church youth programs and Bible study groups.
