Yves Jodouin was out of the Children's Hospital of Eastern Ontario on a day pass on July 2nd, 1984. He was living there and undergoing treatment for Anorexia Nervosa and was supposed to be going to see a movie. At 7 pm, Yves called his grandmother to tell her he was delayed in coming back but would be there soon. No one ever saw or heard from him again. When Yves was last seen, he was 16 years old, 4'9," and 84lbs, with short dark blonde hair and hazel eyes. He has a large scar on his left forearm. If he is still alive, he would be 55 years old this year.
