According to the Army document, Rossi was doing his work in early 2000, then after his factory burned down, he returned to Italy to continue his work there.
According to THIS article, Rossi was arrested just before 6/1/2000 (the date of the article). The article states that he had been a fugitive in the U.S. for a year, and that he had a return ticket for 6/5/2000. So it may be that his "plans to continue his work in Italy" were forced on him by the Italian police.
The article also mentions that this arrest was for "gutting" a company as it was going into bankruptcy, transferring all the assets out of the country.
The article also mentions that Rossi's conviction for dumping toxic waste had already been overturned at this point, so this arrest was a separate issue.
THIS article, from 10/20/2000, states that Rossi was sentenced for eight years for bankruptcy fraud.
THIS article, from 11/24/2004, states that Rossi was acquitted for toxic waste dumping charges. It specifically mentions that he was still awaiting appeal on his 2000 conviction for bankruptcy fraud.
So, based on everything I was able to dig up, there is no sign of Rossi being acquitted on that last, 8-year conviction.
Obviously a problem digging into Italian judicial records ~ I didn’t have any luck either. Bet Amanda could help us with this. Maybe someone should approach her about joining FR. She had a lot of friends here.
