On April 20, 1999, Eric Harris and Dylan Klebold opened fire on classmates at Columbine High School in Colorado. Rachel Scott was the first person killed in the attack and her writings have become the foundation for a nationwide campaign to eradicate school bullying. This week, Rachel's Challenge came to Calloway County Middle School. Jacque Day met up with a student who says he hopes to participate in a "chain reaction of kindness."
