Overweight bully falls out of the canoe, Drowns.

A little group of friends go canoeing(if that's a word)
I think they brought with an overweight bully to teach him a lesson. I'm pretty sure they didn't intend to end his life. But he drowns after he falls out of the canoe.

I think the characters are in their early teens.
Do not remember more.
