A decade after his daughter was shot and killed at school, a father honored his daughter's life by spreading kindness.

Rachel Scott was the first victim of the Columbine shootings in April 1999.

On Wednesday, her father Darrell Scott issued what he calls Rachel's Challenge to students at Fork Union Military Academy in Fluvanna County.

One month before the shootings, Rachel wrote an essay asking people to start a chain reaction of kindness. Her father is spreading that message, hoping to start that chain. One student says he can see how such chain reactions seem to connect many things.

Cody Peck, a senor at the academy, says, "I learned that chain reactions happen all over the world and how a chain reaction led up to the Columbine event at Columbine High School through Hitler's birthday and how even that the chain event through Rachel's diary led up to something else that changed the world even more than what had happened that day and for the greater of everyone around us."

Darrell Scott repeated his presentation at the academy Wednesday night.
