Hard to pass on the blame here.
On the one hand, if the bus driver did indeed secure the bus taking reasonable precautions (I'l give the benefit of the doubt on this one based on the information presented, of course), then I don't think he's at fault.
As for the kid, he did commit the act, but how responsible can he be at the age of eight. Parents? Well, they might be partially responsible, but again, there are limits to just how much parents can control a child. But since he is under their responsibility until the age of maturity, I suppose the parents could be held responsible. It's clearly not a case of intentional murder, however, and so I suppose financial compensation might be an approapriate charge against the parents (civil case?).
Looking at it that way, I'd conclude that financial compensation on the part of the boy's parents to the girl's parents would be the most approapriate charge.
