Chris benoit death?

okay look im still not over this chris benoit tragedy and do not belive he did it,here is one big reason why....16 hrs befor the bodys were found by the police approxmetly 3 posts were made on wikipedia that his wife has been dead and the posts were from conneticit and austrilia so he couldent have done them. so tell me how would anyone know 16 hrs before police did that his wife was murdered?
