He's dead, robbed and shot at gun sight, I can't even login to his account unfortunately, I'm his cousin.
If his estate is taking care of any unpaid debts it would be best to let them know about this one. I'm sure they won't care since it's not fiat, but you have a moral obligation to let them know.
Other than that, I see no reason for you to lie about this, but without any proof I'm not sure why you posted an update on this thread.
