Ever since two middle-aged men with Japanese passports were caught in Italy this month trying to smuggle a purported $134.5 billion in United States government bearer bonds into Switzerland, the Internet has been abuzz with theories. In all, the Italian financial police and customs guards confiscated 249 paper bonds, each supposedly worth $500 million, and 10 bonds with a face value of $1 billion each. After reports of the seizure began to trickle out of Italy, the blogosphere sprang into action, the ponderings fueled by suspicions that the mainstream media was willfully ignoring the tale. The story took on greater life after Italian authorities - who have refused to talk about the scandal - declined to declare the bonds fakes until they were examined by Washington. Col. Rodolfo Mecarelli, the provincial commander of the financial police in Como, said the investigations were focused on understanding who these men were and where they were from." Also unknown are the whereabouts of the two men, who were released after being stopped in early June. "The men were questioned, but not arrested," said Naoki Oyakawa, an official at the Japanese consulate in Milan. He said the two men had valid Japanese passports, but he would not elaborate further on their identities. "We don't know where they are now," he said. "We have had no contact with the two men. They have not asked us for our help." What the bonds were for remains unclear. "It's not the sort of thing that you can just go into a bank and convert," said Colonel Mecarelli. "But they may have been useful to guarantee business deals among people who don't use cash." Agencies that deal with financial crimes, including Europol, declined to comment while the Italian investigation was still under way."
