Two Chrysler officials pleaded innocent to fraud.

The executives, Allen F. Scudder and Frank J. O’Reilly, managed Chrysler assembly plants during the period covered by a 16-count grand jury indictment in St. Louis charging that they conspired to commit fraud on vehicles that were driven by company managers, with the odometers disconnected, and then sold as new. After their court appearance, the pair said they did nothing wrong. If convicted, they could face large fines and one year in prison.
