PHOENIX -- Another suspect in the counterfeit coupon operation that was broken up over the summer has admitted to their role in the scheme.
Amiko Fountain, 42, was in a Phoenix court on Friday where she pleaded guilty to one count of counterfeit mark violation.
Fountain is due back in court on Feb. 1 for sentencing.
Fountain, Marilyn Johnson, and Robin Ramirez were arrested in July after police raided three homes and seized $25 million worth of coupons.
Authorities accused Ramirez of shipping in counterfeit coupons from overseas and selling them on the website savvyshoppersite.com for approximately 50 percent of face value.
Johnson and Fountain were accused of helping Ramirez by operating the site, and assisting with the shipping of the coupons.
Investigators said the scheme bilked manufacturers out of $400 million to $600 million.
All three women originally entered not guilty pleas to charges of illegal control of an enterprise, forgery, counterfeit marking, and engaging in a fraudulent scheme.
Earlier this month, Johnson entered a guilty plea to a charge of counterfeiting. She is also due back in court on Feb. 1 to be sentenced.
