So I did my investigation with people I know and happened to know more from the inside and indeed, that Elder did get the inheritance for his (and his wife's) personal benefit, not the congregations, and everyone is appalled by this.
I wonder if they all would be soo appalled if she had transferred her stuff to the org. But than again, I don't know if the WT would be so stupid as to try to get a will change when the patient is dying and all drugged up as this woman was.
So today is the beginning of a living hell for that greedy elder as he will now face both the secular courts and a Judicial Committee.
