Eleven Sentenced for Refund Fraud Scheme Causing Millions of Dollars in Losses to Online Retailers

TULSA, Okla. - Eleven co-conspirators have been sentenced for conspiring with others to commit wire fraud. This refund fraud scheme targeted numerous online retailers and resulted in millions of dollars in losses to companies such as Amazon, Walmart, Target, Wayfair, Dell Technologies, Kate Spade, Dick's Sporting Goods, HP Inc., and Adidas, among others.

From April 2019 through October 19, 2023, the self-styled Artemis Refund Group ("ARG") engaged in numerous refund-fraud schemes to steal goods from online retailers for its own benefit and that of others. ARG advertised their refund fraud services heavily on online messaging forums, resulting in hundreds of customers being defrauded and placing thousands of refund fraud orders. Some of these fraudulently refunded orders were shipped to the Northern District of Oklahoma, giving rise to venue in
this district.

As part of the refund fraud conspiracy, ARG would instruct fraud customers to purchase a product of their choice from one of the many retailers they targeted, collect information about the order, and then contact the retailer to initiate a fraudulent refund using a variety of methods tailored to that retailer. After ARG successfully deceived the retailer into processing a fraudulent refund, the fraudulent customers would retain possession of the item but still received a full refund of the purchase price. ARG typically charged customers between 15% and 25% of the refunded item's total price. Members of ARG also engaged in the scheme to obtain stolen goods for themselves and resell them on online marketplaces for profit.

Eleven defendants have pleaded guilty to Conspiracy to Commit Wire Fraud and were sentenced:

  • Wyatt Douglas Miller, 24, of San Marcos, CA, was ordered to serve 12 months and one day of imprisonment, followed by one year of supervised release.

  • Antonio Ernesto Munoz, 24, of Palmdale, CA, was ordered to serve 37 months of imprisonment, followed by three years of supervised release.
