What comes to mind when you think about physical evidence that is also biological evidence? It might be a bloodstained shirt or the contents of a sexual assault examination kit. What about a bedspread or a laundry basket? How about a door or a phone booth? These are all items I have seen in evidence rooms across North Carolina in my work with the North Carolina Conference of Clerks of Superior Court on receiving, storing, and disposing of evidence. It is possible that each of these items meets the statutory definition of biological evidence. G.S. 15A-268 establishes that definition and provides explicit requirements around the preservation and disposal of biological evidence, including a specific inquiry into biological evidentiary value that courts must engage in each time physical evidence is offered or admitted into evidence in a criminal proceeding.
