Blackhand if you are happy just knowing the Les was PIC then good for you.
As for the rest of your questions, I am not going to enter into a conversation on a public forum about who I think might have been sitting where. What good does that do anyone at a time like this?
(Except I can assure you I would be extremely suprised if the marine pilot had any involvement in flying the aircraft as he was a MARINE PILOT.
)
All I'm saying is keep an open mind and wait for the outcome of the investigations. Hopefully the CVR will have been "operational" during the critical final stages of the flight!
