What information should accompany evidence when submitted to a crime laboratory?

• A. Case number, item description, date collected, location, collector name, packaging ID, and chain-of-custody documentation
• B. Case number only
• C. Date collected only
• D. Location and lab branding information

Answer: (A)

When evidence is submitted to a crime laboratory, documenting each item with complete, traceable information is essential to preserve its integrity and make it usable in court. The set includes a case number that ties the item to the specific investigation, and an item description so the lab knows exactly what is being analyzed. The date collected and the location where it was found establish the origin and timeline, which help with contextual relevance and cross-referencing with other evidence. The collector’s name provides accountability for who collected and initially handled the item. A packaging ID helps prevent mix-ups and ensures the item remains properly labeled and contained during transport and storage. Finally, chain-of-custody documentation records every transfer of possession or control of the item, creating an unbroken record that demonstrates the evidence has remained secure and unaltered from collection to submission and through analysis. Providing only one or two of these elements would leave gaps in the traceability and integrity that the lab and the courts rely on, which is why a complete set of information is required.
