A federal judge sentences a Springfield man to more than two years in prison for selling more than 4.2 million pounds of corn that was falsely labeled as organically grown.  Judge Ann Aiken told Harold Chase, 55, on Wednesday: "You made a big mistake to commit this crime in Lane County.” She noted the area's strong interest in pesticide-free foods. Chase pleaded guilty in December to a single count of wire fraud. Court documents say chase collected an extra $190,000 by passing the conventional grain off as organic corn.
