"""""""""The FBI have a record of a phonecall between RFK and someone (can't remember who) asking (of Marilyn) "Is she dead yet.""""""""
That phrase is a 'dead' giveaway! I posted the same tip off to the cop interrogating Diane Downs the mother who shot her kids. She was simply not credible as a concerned mom.
Same thing with KE who was quoted as saying;"maybe than can save her" almost confirming that she was beyond saving. Subtle, but telling.
KE didn't say "yet" - but she *did* ask "Is she dead?" to Howard on the phone.
