How do you prove a negative?
They have found no trace of a body. They cannot "know" there is a body in there, unless they find a trace. Our finest cave divers have searched every accessible inch. I believe there is not a body in the cave.
That doesn't mean there won't be a ghost, though . . . .
I didn't know they've found no trace of a body. Last I read was they wouldn't comment either way. I was talking about if they knew for sure he was in there, the decent thing to do would be to say so. Don't even get me going on ghosts.....
