What really happened to chris,nancy and daniel benoit?

...also i have another theory....on monday night raw during the benoit tribute,chavo said he spent the night at chris's house a few nights before...he spent the night and had dinner with the family...have the police questioned chavo? chavo was also the last 1 to be with eddie...and he said he spoke to benoit and benoit ended the call with 'i love u chavo'..... theres more.....chris benoit started wwe in ecw...he was traded and had 1 match in ecw last week( ending his career in ecw) was this planned ?? and by who?? what about the wrestler in calgary or from calgary who was also found dead last weekend??shane somthing?? he was a good friend of benoit....or theres this.......benoit came home from the doctors,just after picking up a perscription...he suffered with depression and other things...its said that his wife and him had been arguing about him staying home with the son more to help raise him...mabey he just snapped...i mean after years of holding in all this anger and emotions
