An 81-year-old former prisoner of war and his 46-year-old son received prison sentences Friday in U.S. District Court in Spokane for a fraud conspiracy involving the sale of locomotive and diesel engine parts to customers worldwide. The younger of the two, Frederick Manfred Simon, was the former president of Railway Logistics International Inc. and its predecessor, Engineering International Corp. Judge Frem Nielsen sentenced him to 125 months in federal prison and ordered him to pay $594,993 in restitution to two dozen corporations in England, Spain, Mexico, Germany, Switzerland, Canada, India and the United States.
