Three people were arrested on Feb. 17 in connection with a counterfeit money operation being run out of an apartment in central Tucson, authorities said.

34-year-old Krista Blanchard was booked into the Pima County jail on charges relating to the manufacturing and passing of fake counterfeit bills. A three-month investigation into the operation began after fake $100 bills began turning up in the same stores around town.

Tucson Police, with help from the U.S. Secret Service, found the men suspected of passing the fake money, through surveillance video and help from witnesses. 19-year-old Cody Anderson and 21-year-old Joshua Blake were arrested without incident.

Search warrants led police to Blanchard, who they say used a combination of new technology and old techniques to make the very realistic fake bills.
