Isn't this a separate issue to the one the grandparent was complaining about? I can't see anything about child porn related to this person, just a lot of talk about money laundering.

Also, are you sure there were no charges filed? Some cursory googling turns up articles including a PDF of the indictment [1] and more-recent articles seem to refer to an ongoing process [2].
