The duo that carried out several robberies before Christmas isn't quite as notorious as Bonnie and Clyde, but the feds are nevertheless using the monikers. Naming the crooks helps officials keep track of cases and might ring your bell if a suspicious pair enters a bank near you, writes 9News . "Clyde," according to the FBI, allegedly hit a Sinclair gas station in Greeley twice---on December 5 and 19---brandishing a gun and fleeing with cash (via CBS4 ). On December 15, "Bonnie" joined him for a stick-up at a Premier Cash Advance. And on Christmas Eve, the two made a haul at the Guaranty Bank and Trust, where they waved handguns. The FBI and Guaranty Bank and Trust are offering up to $10,000 for information leading to arrests and convictions in the robberies, notes The Greeley Tribune .
