PRINCEVILLE - It's been fourteen years since the tragic shootings at Columbine High School in Littleton, Colorado.
One of the victims was a student named Rachel Scott.
Rachel, as described by friends and family, was the kind of person who loved to do things for others and stood up for victims of bullying.
In her memory, her family has started an anti-bullying group that takes its message to schools across the country.
Monday, they asked students at Princeville High School to accept what they call "Rachel's Challenge", a pledge to be nice to their peers.
"It's about empowering people to recognize that when they go to school each day, sure, people come to school with smiles on their faces, but everyone is going through something," says Meg Murray with the organization. The importance of kindness is paramount."
Rachel's father shared her story at the high school Monday evening.
