A federal jury has convicted a former member of the Chicago Board of Trade on charges that he and three others used a wig and other disguises to make illegal trades worth $308,000. Thompson B. Sanders was found guilty on 11 counts of conspiracy, wire and commodities fraud and interstate transportation of stolen property. He faces as much as 55 years in prison and $1.3 million in fines. Sanders said he would appeal the decision. The government charged that Sanders and three accomplices participated in a scheme in which one wore a wig and used fake credentials to gain access to the U.S. Treasury bond trading pit at the board of trade.
