LeFevre the Younger was the President and CEO of Lending Partners.
A single-engine Cessna crashed Monday in Grundy County, but the wreckage has not been found.
The authorities have not specified the cause of the accident. Sheriff Rodney Herring said the plane was on its way from Moberly to Kirksville, but veered off course before crashing.
The bodies of the two men were found on the plane.
