Seventeen-year-old Richard Castaldo was the last Columbine shooting victim to leave the hospital.
Castaldo, paralyzed from the chest down after being shot several times, wheeled himself out of the hospital and bravely faced the media.
"I try not to think about what happened to me too much," Castaldo said, "because I don't think it will really help in the long run."
He thanked those who helped him during and after the shooting and said he's not focusing on the past. Instead, he said he wants to work for gun control.
Castaldo will return to Columbine for his senior year in two weeks.
