The Ames Police Department is looking for the person who may have lost a big stack of cash. Police say a good samaritan turned over a "significant" amount of money recently. They're hoping the rightful owner can come forward and claim it. Authorities aren't release many details about the money. They want the owner to prove it's theirs, so all they're confirming is that it's green and has numbers on it. If you think the money could be yours, call Ames police. Officials said they want the owner to provide details like denominations, or possible locations where it could have been left.
