Even though she moved and changed her address there may be speedy trial issue because the event "Allegedly" occurred 3 years ago. That said, it could be a misdemeanor or a felony charge depending on the amount they are claiming she stole. Depending on which county and state where she is being prosecuted they may have a website with additional information. I would suggest that she not say anything to anyone and speak to a lawyer immediately. If she cannot afford an attorney the court will appoint her one. The punishment could be as little as a deferred entry of judgment program where the charges are dismissed after completion of a brief course or it could be much more and include in custody time if the amount is significant. It may also be possible to defend the charges completely.
