Has the Mafia moved on from garbage trucks to ships carrying nuclear waste? An informant in Italy has told authorities he blew up three ships carrying the deadly cargo. Apparently, there is much money to be made by bypassing normal nuclear-waste disposal guidelines. A video taken by an underwater robot camera shows the ruins of a sunken ship and toxic yellow canisters by its side, though tests of the site off Italy's southwest coast are still under way. Italian authorities are now looking into at least 30 other suspicious shipwrecks. If the informant’s confession turns out to hold water, it will indicate a new, environmentally damaging direction for the Mafia.
