A Greenville man has been arrested and charged with fraud and theft for opening mail and taking its contents while working as an employee of the Eldorado Post Office.The Preble County Sheriff's Office says an investigation began in late May after receiving complaints that mail was possibly being opened and money and/or gift cards were being removed before being delivered to homes in the Eldorado area.Deputies say investigators contacted the United States Postal Inspector's Office and they assisted with the investigation.Officials say an employee, 21-year-old Austin C. Stutsman, was identified as a suspect, and he later admitted to opening mail since he began working at the post office in December of 2021.According to officials, Stutsman confessed to opening mail that looked like it contained greeting cards in search of cash or food gift cards and admitted to finding and taking both on several occasions since his employment began.Officials say they also discovered that Stutsman was issuing money orders from the Post Office while he was working and then cashed them for his own personal use, on one occasion even issuing an order under a friend's name.Investigators say they believe more than $2,000 in money orders were issued.Stutsman has been charged with identity fraud and theft, both fifth-degree felonies.He is currently in the Preble County Jail.
