The male defendants worked in the video game department at the Miccosukee Casino. They tampered with the computers in electronic gaming machines, causing those machines to generate false and fraudulent credit vouchers or tickets.

The men enlisted other conspirators to exchange the vouchers for cash at ATMs located on the casino floor, at floor cashiers, or the casino treasury.

Casino records indicate that the defendants and their co-conspirators stole approximately $5.2 million in cash from Miccosukee Gaming.

Federal officials say the defendants used the stolen money to purchase and maintain residences and investment properties, purchase vehicles, vessels, and Florida Prepaid College Plans for their children, and to pay for travel and household expenses.

Each defendant, now awaiting sentencing, faces a maximum term of 20 years’ imprisonment for money laundering conspiracy.
