DEFINE: Chain of Evidence
process and record that documents the handling of evidence from the time of collection to its presentation in court, ensuring its integrity. It is also known as the chain of custody, and it tracks who obtained the evidence, where and when it was collected, and who has had possession or control of it throughout its lifecycle. A complete chain of custody is crucial for evidence to be admissible in a legal proceeding.
