I agree, and further: the death of a human being is a legal matter, and laws require that a death be reported. Concealing a death is a crime, and a pretty serious one; medical professionals who participate in doing so would likely be looking at losing their licenses to practice medicine, as well as facing legal consequences.
I don’t believe that McConnell is dead, but he is almost certainly far more incapacitated than his staff has been willing to let on.
