What is the main focus of the final survey in a crime scene investigation?

The primary aim of the final survey in a crime scene investigation is to ensure that no evidence has been overlooked and that all potential evidence has been collected appropriately. This step is crucial as it serves as a comprehensive checklist for investigators, allowing them to verify that every piece of evidence has been accounted for before concluding the investigation at the scene. This process helps prevent future legal challenges by ensuring that the investigation is thorough and that nothing vital has been missed.

While collecting more evidence is important during the investigation, the final survey is specifically about confirming that all evidence has been gathered rather than seeking out additional new evidence. Reviewing findings with experts is part of the overall investigative process but occurs at different stages, often after the local collection and before trial preparations. Similarly, summarizing the investigation in a report is typically completed after the evidence collection is finalized, serving as documentation rather than a focus of the survey itself.
