(Portland, OR) -- A federal judge has sentenced a woman to prison for stealing from elderly Oregonians. Court documents show 34-year-old Rexona Caldararu, a Romanian national in the country illegally, would watch elderly customers as they checked of grocery stores, memorize their PIN, follow them into the parking lot and claim they dropped cash. She would insist on helping to put the money in their wallet while stealing their debit card. She would withdraw money and make purchases. Caldararu defrauded 12 people and stole more than 73-thousand-dollars.
