Forensics – Crime Scene Practice Test

Labeling on evidence packaging provides essential, at-a-glance information that keeps the investigation organized and the evidence trustworthy. The best labeling clearly identifies what’s inside, links it to the correct case with a unique item reference, and communicates how the item must be handled to preserve its integrity.

That means including a description of the contents so anyone handling the package knows what it is without opening it, the case number (and an item or evidence number) to tie the item to the record, and specific handling instructions such as storage conditions, tamper-evidence requirements, or any precautions to prevent contamination. This combination supports quick verification, accurate documentation, and the chain of custody, since every transfer or check can be traced back to a labeled item.

For example, a labeled bag might read: “Bloodstain on fabric, case 2024-047, item 1, collected by Officer X on 2024-05-12, refrigerate, do not open outside lab.” This ensures the right item is sent to the right lab, preserved correctly, and connected to the investigative file.

Decorative labels serve no forensic purpose, labeling isn’t optional, and a label should do more than just record a case number. The content, case linkage, and handling instructions are all critical to preserving evidence integrity and admissibility in court.
