What should be done if evidence is suspected to be out of reach from the main crime scene?

Conducting a concentric circle (spiral) search is the optimal response when evidence is suspected to be located away from the main crime scene. This method involves starting at a central point and systematically working outward in a circular pattern. This technique is effective in ensuring that all areas surrounding the primary scene are thoroughly searched, leaving no potential evidence overlooked. It helps maintain a clear and organized approach to searching, maximizing the likelihood of discovering relevant evidence that may be critical for the investigation.

While other options may seem relevant in different contexts, they do not address the need for a comprehensive search of the area surrounding the main crime scene. Ignoring the area would risk missing important evidence, calling for backup could be helpful but doesn’t specify a search method, and solely documenting what can be accessed skips the essential step of actively searching potential areas for evidence.
