U.S. Secret Service

The case started in December when Casper police arrested the men on single charges of credit card fraud.

The Arizona credit union told a detective that their clients' credit card numbers had been used at ATMs in Laramie, Rock Springs and Casper.

James Watkins told a U.S. Secret Service agent that he alone printed the counterfeit bills, and he had been counterfeiting for several years.

Some of the confiscated counterfeit bills had identical serial numbers.
