Someone spoke to him apparently in the early days and he said he "signed some documents" but wasn't really involved with the operation.
This is hidden somewhere in the last 800 or so pages.
Without knowing what he signed, its kind of hard to prove he is complicit or liable. But if at least he is aware of "labcoin" then he should be able to point to the right people.
Personally I wouldnt waste my time finding a possibly imagined chinese from ghana ("sam"), Id focus on theswede first. He is (I think?) in the US, legally liable for facilitating and promoting public sales of unregistered securities and should know the identity of the other people behind labcoin if there is anyone else behind it.
Maybe this is a start:
