I was tucking the lower half of the mountain with a Race Crew buddy. He was way ahead of me. I noticed some people down but I kept going. He had booted a child in the head. The child was a girl down on the backside of a knoll. He didn't see her till it was too late. The impact knocked him out. When he came to, he was alone in a clinic, he walked out of his room to see the medics pronouncing the little girl dead. NO HELMET!
