How should you document and preserve potential evidence or clues at a SAR scene?

• A. Photograph and map clues; note time and location; preserve chain of custody; report to ICS.
• B. Move clues to a central location before documenting.
• C. Document clues after incident is closed; store in file.
• D. Destroy clues after noting.

Answer: (A)

Documenting and preserving clues at a SAR scene relies on capturing an accurate, intact record of what’s found and when, while keeping a clear chain of custody. Photographing clues records their appearance, condition, scale, and context exactly as they are, which is essential for later review and analysis. Mapping their locations shows how they relate to each other and to the terrain, helping reconstruct movements, routes, or points of interest. Noting the time and exact location ties each clue to a timeline, which is crucial for understanding the sequence of events. Maintaining chain of custody tracks every person who handles the clue, ensuring its integrity and accountability if the information ever needs to be reviewed or presented. Reporting findings to the Incident Command System integrates the evidence context into the overall incident management, keeping actions coordinated and preventing gaps or duplication.

Moving clues to a central location before documenting can destroy contextual information and contaminate the evidence. Waiting to document after the incident is closed or simply storing clues in a file risks losing vital time stamps and chain-of-custody details. Destroying clues is not acceptable and undermines safety, accountability, and any potential investigation.
