Rachel Scott was the first student killed in the Columbine High School shooting in 1999. Darrell Scott, Rachel's father, established Rachel's Challenge to perpetuate his daughter's example and the two-page "Code of Ethics" she wrote a month before her death at the hands of the perpetrators of the Columbine High School shooting, Eric Harris and Dylan Klebold. This code of ethics had included the words: "Compassion is the greatest form of love humans have to offer", and Darrell Scott has stated his belief in this message forms the basis for what he both speaks at public appearances, and has written as an author.
