A rash of phony bills of multiple denominations has police suspecting there may be a counterfeiting ring in Warren County.“There are too many popping up for it to be a coincidence,” said McMinnville Police Lt. Nicole Mosley of the sudden influx of counterfeit bills “We’ve gotten quite a few in the past few weeks. Usually you will get one and then not see another for many months. Now, they’re popping up everywhere.”Mosley said an unusual characteristic about the recent rash of counterfeit bills is there are many denominations being passed.“We’re talking about $5s, $10s, $20s and $100s,” Mosley said.
