You can't charge her with anything; only the DA can do that. You can report it to the police but prepare yourself for the laughter when you say this happened 6 years ago. I doubt anyone will act on your complaint.
You may have a civil claim, depending on how the facts play out precisely on your claim. Fraud claims are subject to a statute of limitations, which limits the total number of years you can wait to bring suit. How many years you can wait to bring suit varies from state to state. But at six years, it is likely you are close to if not already beyond the statute of limitations period.
