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

The final survey in a crime scene investigation primarily focuses on assessing whether all evidence has been collected. This critical step ensures that investigators have thoroughly examined the scene and accounted for all potential evidence before the site is potentially altered or released. By conducting this comprehensive assessment, investigators can confirm that no crucial information has been overlooked, which is vital for the integrity of the investigation and for any subsequent legal proceedings. This final evaluation helps in securing a complete understanding of the crime scene, enabling investigators to construct a more robust case based on the evidence collected.

Other options, while relevant to the overall investigation process, do not encapsulate the primary focus of the final survey. Collecting more evidence typically occurs during earlier stages of the investigation, and reviewing findings or providing a summary report are tasks that follow the assessment of evidence collection. The main objective at this point is to ensure nothing has been missed before wrapping up the investigation at the scene.
