They thought they were committing the perfect crime, instead, one Indiana couple could be spending the next 20 years behind bars for their million dollar fraud.

Erin and Leah Finan have been arrested in what police describe as an elaborate scheme to defraud the online retail giant Amazon out of $1.2 million and later launder the profits.

According to a report from Fox59, the Finans ordered over a million dollars worth of high-end electronic items and other goods, then reported to Amazon’s customer service that the items were not working properly. As per Amazon’s policy, the items would then be replaced at no cost to the customer. After receiving the replacements, the couple would then turn around and allegedly sell these items to a New York man, identified as Danijel Glumac.

The Finans’ plan went off without a hitch. Using multiple dummy accounts to conceal the fraud, once the merchandise arrived, the couple allegedly sold the items to Glumac below retail cost before the items were transported to New York and sold on the black market.

Their plan fell apart when an investigation was opened by multiple agencies including the U.S. Postal Service, the IRS, and Indiana State Police.

The Star Press reports that the couple pleaded guilty to the fraud. As part of their plea deal, they have been ordered to pay Amazon $1.2 million in restitution and could be facing a maximum sentence of 10 to 20 years behind bars.
