I have two theories to pass along to anyone listening.
I believe Q is not JFK JR. but Caroline his wife. R is John
Also the man called Vincent Fusca who many believe is Kennedy in disguise. The name Vincent means "Conqueror". Fusca in Latin means "The Dark". So Vincent Fusca = "Conqueror of the Dark"
Vincent Fusca lives in Pittsburg and his wife's name is Catherine Fusca. The nickname of Catherine is "Kate". The name on the Coke bottle that Peter Stoupe had in his hearing that the cameraman kept framing in his shot.
