I remember seeing a story like this around here in Hawaii last year, the kid's name was Caleb and he was actually at the school that I work at for a brief period of time.
I forget the entire story, but all I do remember is that he was found unconscious in the family pool at the age of 3. He was not breathing for what was determined to be around a total of 45 minutes, and was pronounced "dead", until they somehow managed to revive him. He lived, but was left with severe brain and other organ damage as well as the inability to walk and breathe on his own.
He's made some improvements and recoveries since then, but whether or not he'll ever make a "full" recovery remains to be seen. After surviving through the better part of an hour without any air though, it's hard to completely rule it out.
Although the event certainly could have turned out to be more tragic, I still imagine that his life as well as his family's lives must have suffered through numerous hardships as a result of the incident and the subsequent rehabilitation.
I'm sure that these people as well as innumerable others, in their grieving, allow themselves to be bombarded by "if only" thoughts at some point -- thinking that if so and so had only done this one thing differently, the incident could have been prevented. Dwelling on these sorts of things for too long tends to lead to blame and animosity, which is really helpful for nobody. As has been stated, the damage has been done, it is part of the past now, and there isn't any changing it; only the future can be changed. The punishment has already been meted out and I'm sure his immediate family is in enough pain already; the additional mud-slinging on top of that is not necessary. I do not think that is how your nephew would like to be remembered, as a reminder of the grief and hate amongst his family.
I hope that his family can get past the "if only" phase and start to look toward the future soon.
