How should evidence be packaged at the crime scene?

Evidence at a crime scene should be packaged securely and appropriately to prevent contamination, damage, or loss. Each item should be collected in separate containers, such as paper bags, cardboard boxes, or plastic evidence bags, depending on the type of evidence. Labels should clearly identify the item, the case number, and the collector's information. Additionally, chain of custody documentation must be maintained to ensure the integrity of the evidence throughout the investigation and legal proceedings.
