What must be included in the labeling of evidence collected?

In the context of evidence management, proper labeling is crucial for maintaining the integrity and usability of evidence in legal proceedings. Including the officer's identification on the evidence label serves several important purposes. It ensures accountability, as it designates who collected and handled the evidence. This is vital for chain of custody, as evidence must be traceable back to the individual to confirm its handling and custody throughout the investigation process. Proper identification also aids in the organization of case materials, allowing for easier reference and verification during trials or further investigations.

While the other options may seem relevant in certain contexts, they do not hold the same level of necessity when it comes to evidence labeling. For example, the case report number could be useful for tracking, but it does not identify the individual responsible for collecting and managing the evidence. Similarly, victim's personal information and witness names may not be appropriate to include on the evidence label, as they can raise privacy concerns and are typically documented elsewhere in case files or reports. Thus, the presence of the officer's identification is paramount for clarity, accountability, and the preservation of the evidence’s integrity in legal contexts.
