(4) Any bullets, clothing, or other foreign objects that are removed from a patient for whom a hospital is required to make a report pursuant to subsection (1) of this section shall be preserved and kept in custody in such a way that the identity and integrity thereof are reasonably maintained until the bullets, clothing, or other foreign objects are taken into possession by a law enforcement authority or the hospital’s normal period for retention of such items expires, whichever occurs first.
