What is the first phase of evidence gathering at a crime scene?

The first phase of evidence gathering at a crime scene involves surveying the scene. This initial survey is crucial as it helps investigators understand the layout and conditions of the scene, prioritize areas for detailed examination, and formulate a strategy for gathering evidence. During this phase, investigators look for potential evidence, assess the scene’s overall status, and identify immediate safety concerns for themselves or others.

Surveying the scene can also provide context surrounding the incident, making it easier to analyze the evidence later. This phase allows investigators to establish a general understanding of what occurred, which is essential before any detailed documentation, evidence collection, or interviews take place. It sets the groundwork for the entire investigation and ensures that no critical elements are overlooked as they proceed to more focused evidence-gathering methods.
