         2.    “Discharge date” has the meaning given in s. 968.205 (1) (b).

      (b)    Except as provided in par.

      (bm)    The court shall ensure that an exhibit to which par. (b) applies is retained in an amount and manner sufficient to develop a deoxyribonucleic acid profile, as defined in s. 939.74 (2d) (a), from the biological material contained in or included on the exhibit.

         1.    The court sends a notice of its intent to destroy the exhibit to all persons who remain in custody as a result of the criminal action, delinquency proceeding, or commitment under s. 980.06 and to either the attorney of record for each person in custody or the state public defender.

         2.    No person who is notified under subd. 1. does either of the following within 90 days after the date on which the person received the notice:

            a.    Files a motion for testing of the exhibit under s. 974.07 (2).

            b.    Submits a written request for retention of the exhibit to the court.

         3.    No other provision of federal or state law requires retention of the exhibit.

      (d)    A notice provided under par. (c) 1. shall clearly inform the recipient that the exhibit will be destroyed unless, within 90 days after the date on which the person receives the notice, either a motion for testing of the exhibit is filed under s. 974.07 (2) or a written request for retention of the exhibit is submitted to the court.

      (e)    If, after providing notice under par. (c) 1. of its intent to destroy an exhibit, a court receives a written request for retention of the exhibit, the court shall ensure that the exhibit is retained until the discharge date of the person who made the request or on whose behalf the request was made, subject to a court order issued under s. 974.07 (7), (9) (a), or (10) (a) 5., unless the court orders destruction or transfer of the exhibit under s. 974.07 (9) (b) or (10) (a) 5.
