As a parent I feel bad for this kid's parents who now have to deal with their dead kid being laughed about on the Internet. This is why when your kid runs away, you try to chase after them.
The kid looks a bit odd, autistic maybe? Something doesn't look right with him.
He probably ran off in his clothing, no jacket, etc, and it's COLD in Canada and he probably went to lay down to sleep at night time and never woke up due to hypothermia.
Or he fell down and hurt himself, banged his head, etc.
What I want to know is how many animals gnawled on him. He was probably dead within a day or two of running away. My guess is he was dead in less than 24 hours after running away.
