What is the purpose of evidence laboratories?

• A. To maintain chain of custody by labeling every item
• B. So you can track and know where and what the evidence you collected was
• C. To determine guilt beyond a reasonable doubt
• D. To replace field notes with lab reports

Answer: (B)

Evidence laboratories exist to ensure evidence remains identifiable and traceable as it moves from collection through storage, analysis, and presentation. The key purpose is to document what the item is and where it has been, who handled it, and when, so there is a clear, auditable trail—the chain of custody—that supports its integrity in court. Because of that, the best way to describe their purpose is to provide the ability to track and know exactly what was collected and where it is, along with its current status. Labeling items is important for organization, but it’s only part of the picture; the lab’s role centers on maintaining comprehensive records that show the evidence’s journey and identity over time. Labs don’t determine guilt; they provide factual findings that inform the legal process. Field notes and lab reports complement each other, preserving initial observations while documenting analytical results.
