In all states in this country, the prosecution bears the burden of proof in a criminal proceeding. If the file concerning the criminal action against you has been lost by the court clerk, the prosecution against you cannot prove its case. If the prosecution cannot prove its case against you, then in all likelihood the action must be dismissed.You should contact the county bar association where you live and see if they provide services to help people like you. Even if you had the citation for the petty theft charges against you, I would not send it to the court clerk for the simple fact that you have no duty to do so, and if you sent the citation, you would only be hurting yourself.I would write the court clerk stating you do not have the citation and that unless he or she can find your file, you want the case dismissed keeping a copy of the letter for future reference.Good luck.
