Kai Smart, the son of two-time Olympic freestyle skier John Smart, has died after being buried in an avalanche while skiing in Japan. He was left in a coma and was fighting for his life in the hospital. Despite being flown to Vancouver, the severe lack of oxygen he experienced during the avalanche had destroyed any chance of recovery. John, who represented Canada at the 1992 and 1994 Winter Olympics, paid tribute to his filmmaker son, Kai, who was also the director of the ski film Tien Shan Dream. His organs are being used to keep four other people alive.
