NASHVILLE, Tenn. (AP) -- Three more employees of the truck stop chain owned by the Cleveland Browns' owner and Tennessee's governor have pleaded guilty in what authorities call a scheme to cheat trucking firms out of rebates.
Regional sales manager Kevin Clark pleaded guilty to mail fraud in federal court in Knoxville on Tuesday.
Knoxville media report that Holly Radford, an account manager, and salesman Jay Stinnett entered similar pleas later in the day.
Prosecutors allege that the sales team of Pilot Flying J, the country's largest diesel retailer, short-changed trucking companies to boost profits and commissions.
Pilot is run by Browns owner Jimmy Haslam, the brother of Gov. Bill Haslam. Jimmy Haslam has denied any personal wrongdoing.
Two other Pilot employees pleaded guilty last month.
