I personally knew of some Bible Students who knew of the facts, and I was told that he was visited by some friends because of failure to attend a convention in which he was speaking, he was found at the bottom of the stairs to the basement, apparently tripped during a drunken stupor, cracked his head open and was died, the rats were eating at him. That's what I was told, still it is hearsay, but you know what? The Society version is also hearsay, I have never seen Rutherford's supposed grave, or pictures, no bethelite I ever met knows where the guy is buried, only rumors of where he could be, I still say he's in beth sarim, and Franz, admitted to this in private conversation, senile? Maybe!
As to Russell? He doed on board of a trian heading through Pampa, Texas, I have the death certificate, no autopsy was made, because everything was so botched up that personally, I think it may have been a conspiracy, there have been rumors for years that Russell was poisoned, and that Rutherford had a part in it, I met a JW in Europe who claimed to have proof of this, most Bible Students I know dismiss the idea.
