Your missing the point..the original cause was being bullied..Like it or not that is the reason..and so the boy retaliated..if that had not happened, the bully would still be alive.
This person died because people do not understand until it is too late that if you don't provoke, then people won't retaliate.
Either way he dies from lack of oxygen supply.
You should send a message to MYTHOSSS. He seems to be having the same problem.
my guess is popped a blood vessel, dislocated his neck, or no circulation. Any way you look at it, he ultimately died because he pissed off a boy enough to have him kill him.
why do you care o.O
