There are a great many unanswered questions from the information so far available to us. Do you not find it odd that apparently the only things missing are those which relate to the dispatches?

Of course it is unclear as to when he was found and wheither he was found dead or died sometime thereafter.
I note from the book that very few died at the hand of others. The book is worth a read. Certainly an area unknown to me. <;^}
