GILLETTE (WNE) — The Campbell County Sheriff’s Office is out real money after inadvertently taking $120 in counterfeit bills from a man who was booked into the jail for fraud.

Edwardo Vlahos, 43, was arrested Oct. 19 on suspicion of felony shoplifting. As part of his booking process, Vlahos turned over some money he had with him to put on his commissary account. When he was released on bond Oct. 21, the department returned $261.69 to him on a debit card.

However, a sheriff’s office worker overseeing the inmate commissary later reported that the counting machine wouldn’t accept a $20 bill and two $50 bills that Vlahos had allegedly turned over at the time he was booked, authorities say. The $20 was determined to be a counterfeit with a detecting pen while the $50s had the same serial number.

When contacted by police, Vlahos denied knowing that the bills were counterfeit.

However, prosecutors charged Vlahos with a new count of forgery; the felony was tacked onto a September case, in which Vlahos is alleged to have passed counterfeit bills at a restaurant where he’d worked.
