A former bond futures trader at the Chicago Board of Trade is now the subject of a nationwide manhunt after a fugitive warrant was issued, Assistant U.S. Atty. Ruben Castillo said. Daniel Dewey, 39, was among 10 brokers, traders and other people named in indictments by U.S. Atty. Anton Valukas. The men were accused of four separate schemes at the Board of Trade and Chicago Mercantile Exchange.
