Ok that's great! He now has access to his passport that he doesn't probably even need!
I really would now ignore them, including any emails he sends. You get to make the decision to be done here now. You have done all you can. He is gone, his stuff is gone, whatever he is up to can be ignored.
As your Sister and Mom aren't really around, they are just guessing, they don't know that you have actually been out doing things with the kids, they just don't know. Yes, it's hurtful, but again, they don't really understand.
