IDAHO FALLS â A local man who reportedly threatened a gas station employee was charged with robbery and other crimes Monday. Juan Carlos Rosales, 28, of Idaho Falls, was arrested Saturday night after a worker at Hitt the Road reported a man had robbed the store wearing a black mask and black beanie. The worker said Rosales had his right hand in his shirt as if he were holding a gun, but told Bonneville County Sheriffâs Office deputies she did not see a gun. After the employee gave Rosales the money in the cash register, he left in a silver car, according to the probable cause affidavit. The gas station later estimated he stole $944.87.
