Computerworld - "Michigan man charged with selling counterfeit Microsoft software"
"IDG News Service - A man from Michigan was arraigned in a U.S. federal court on Thursday on charges of mail fraud and selling counterfeit software worth over US$1.2 million that he purchased from China and Singapore, the U.S Department of Justice said Thursday."
"Edward allegedly distributed counterfeit copies of Office 2003 Professional and Windows XP Professional by selling copyrighted works on eBay and then using the U.S. Postal Service to deliver the counterfeit software, according to the indictment which charges Edward with five counts of criminal copyright infringement and one count of mail fraud.The indictment charges Edward with making more than $140,000 between May 2008 and September 2010 by selling more than 2,500 copies"
If the DOJ has records indicating the number of sales, they likely have records stating who bought what, when. That doesn't mean anyone else will be charged based on the guy's records, but can't totally rule it out either until the DOJ says so.
