Do not post any more of those words, because it can be part of a seed for the recovery of his Bitcoin wallet. If you find the identity of the person, his family might need that to decipher his seed and to recover his Crypto currencies. That might be worth a lot of money, if he stashed a lot of coins in a wallet somewhere.
Why did you not just finger print the guy and see if something pops up on his identity, linked to his finger prints? Good luck... it would be better to deal with a trusted Crypto expert and not some random anonymous person on the Internet.
