That's possible, but after the family having to view John Kennedy's head explode on television for nearly fifty years, and of course the photos of Ted's Oldsmobile being pulled out of the water, the family has become much more guarded about this kind of stuff. One of the reasons Ted had the military around during the search, recovery, and disposition of the bodies of JFK Jr was so photos of his remains wouldn't show up on the net.
Ted's circling the drain. He's getting old, and has never taken care of himself. Could be true or not, but he's in the final stages, whatever the truth of this report is.
