Police, along with the Secret Service of the United States, continue to investigate the case of the counterfeit bills circulating throughout businesses in Laclede and surrounding counties. Someone took several $10 dollar bills and turned them into $100 dollar bills which have actually passed the pen test for authenticity. As of today, police have confiscated 5 of these counterfeit bills and they recommend every business owner check the documents thoroughly before accepted them in the time being.
