When the petition is not summarily dismissed, the court shall order that all evidence in the possession of the prosecution, law enforcement, laboratory, or the court that could be subjected to DNA analysis must be preserved during the pendency of the proceeding. The intentional destruction of evidence after such an order may result in appropriate sanctions, including criminal contempt for a knowing violation.
