Does anybody know if there is any kind of ongoing investigation as to what happened with Chris Benoit and his?

family's deaths? I mean yeah by now everyone knows that he killed his wife and kid and then killed himself but it just doesn't make any sense as to why if he was so close with all of these people in WWE and he was making all this money that he would just lose it and snap one day after how many years of doing this and living his life this way that he would just kill his own child one day, then the next day kill his wife and then the next day hang himself, which makes you wonder how could his wife not know where her own child was for a whole day? anyways I know I am not the only one who is having a hard time believing that this is really what happened, I guess when you hear something really tragic like this no answer will really make things any easier
