Seems fair to wonder, but to put out statements that he is gone without knowing this for sure is not helpful.

I believe that my late father also knew Jay's father professionally. I have, through my dad and other more distant relatives, a deep connection to Montefiore and Albert Einsten, particularly the pathology departments. There's no way these people got involved with a fraud. It seems Jay's father is the one who will be leading the Alzheimer's trials when they get started.
