Which item is not considered essential documentation at a recovery scene?

• A. Genetic sequencing results
• B. Photographs
• C. Sketches
• D. Chain-of-custody form

Answer: (A)

Documenting a recovery scene aims to preserve context and maintain a clear chain of custody. Visual and spatial records, along with a traceable transfer of evidence, are essential for later analysis and legal defensibility. Photographs capture the scene, the condition of remains, and surrounding evidence in a way that details can be revisited accurately. Sketches provide a quick, interpretable map of layout, distances, and orientations that help reconstruct how and where items were found. A chain-of-custody form records every transfer of the evidence from collection onward, protecting the integrity of the remains and associated materials.

Genetic sequencing results, while crucial for identification and analysis, are produced after collection in a lab and do not serve to document the scene itself. They belong in lab reports rather than the field records, which is why they are not considered essential documentation at the recovery scene.
