Two more members of the Pilot Flying J sales staff have pleaded guilty to defrauding customers at the truck-stop chain owned by the family of Cleveland Browns owner Jimmy Haslam and Tennessee Gov. Bill Haslam.

On Monday, Regional Sales Manager Michael Scott Fenwick pleaded guilty in federal court in Knoxville to conspiracy to commit mail fraud. The charges are related to a scheme in which Pilot customers were cheated out of the rebates and discounts they were supposed to receive.

Regional Account Representative Janet Welch also pleaded guilty to a mail fraud conspiracy charge on Monday.

Five other employees have pleaded guilty to similar charges since an April 15 raid by federal agents on Pilot's headquarters.
