N.C. Gen. Stat. § 15A-280
Within 90 days after the nontestimonial identification procedure, a return must be made to the judge who issued the order or to a judge designated in the order setting forth an inventory of the products of the nontestimonial identification procedures obtained from the person named in the affidavit. If, at the time of the return, probable cause does not exist to believe that the person has committed the offense named in the affidavit or any other offense, the person named in the affidavit is entitled to move that the authorized judge issue an order directing that the products and reports of the nontestimonial identification procedures, and all copies thereof, be destroyed. The motion must, except for good cause shown, be granted.
