MASON CITY — A Hampton man charged in both Cerro Gordo and Franklin counties for purchasing credit card numbers on the internet and using them around north-central Iowa has pleaded not guilty. 28-year-old Wayne Davis was arrested last month and charged in Cerro Gordo County with ongoing criminal conduct and three counts of unauthorized use of credit cards, as well as one count of unauthorized use of a credit card in Franklin County. A criminal complaint says Davis was identified by an employee who turned his identification into the authorities, with the Iowa State Patrol conducting a traffic stop on Davis where a credit card skimmer, computer and cards were allegedly seized. The complaint says an examination of those items revealed that Davis was purchasing card numbers on the dark web. A search warrant at Davis’ residence allegedly produced stolen credit cards and a card skimmer. Davis’ arraignment hearing was scheduled for Tuesday, but online court records show that he filed a written plea of not guilty in Cerro Gordo County District Court. No trial date has been set. He remains in the Cerro Gordo County Jail on a total of $51,500 bond.
