This is one of my favorite conspiracies, especially the DJT rally footage showing someone who looks exactly like an aged Caroline in the crowd. Vincent Fusca is an interesting possibility, but wouldn't even consider it without that woman.

For this evidence though, I feel the email author talking about JFK Jr. could easily be intending RFK Jr., because the tone of it suggests someone already in the public eye, and he was a presidential candidate (and concerned with health shit, as she relates). Maxwell doesn't say she saw him after the year of his death.
