The U.S. Marshal Service will hold an inventory auction next month at the former Gentry Brothers Tractor Supply in White County. Gaston & Sheehan Auctioneers says the auction is set for 10 a.m. Saturday, August 26, at Gentry Brothers Tractor Supply. Pre-bidding runs from August 7 to the 25th. The company was closed just before the first of 2017. Agents say owners Jeff and Wendy Gentry have been under investigation by the FBI since that time. At least three civil lawsuits have been filed, alleging the Gentrys ran a Ponzi scheme through the business. This week, the U.S. Attorney’s office announced Jeff Gentry had been charged with one count of mail fraud and one count of money laundering. He faces up to 40 years in prison on the charges.
