New information has been uncovered that Daniel, Benoit's son, had Fragile X - a form of mental retardation often accompanied by autism. This was reportedly a family secret, unknown to the public or the WWE administration.

Also, unknown to the WWE administration, Benoit's wife had previously filed for divorce later withdrawing that request.

No one will be able to say what the cause was until toxicology reports come in, but in my opinion, from the nature of the killings it was a very deliberate - no rage involved.
