Which of the following describes the walk-through phase of a crime scene investigation?

The walk-through phase of a crime scene investigation is primarily focused on evaluating the nature and extent of the crime. During this initial phase, investigators systematically observe and assess the scene to gain an understanding of what occurred. This evaluation helps identify crucial details such as the sequence of events, types of evidence that may be present, and the overall context of the crime. It serves as a crucial preliminary step that guides subsequent actions, including evidence collection and documentation.

This phase involves making initial observations about the layout of the scene, potential evidence locations, and the condition of the crime scene. It helps formulate a strategy for the investigation and ensures that significant aspects of the scene are preserved and documented properly for further analysis.

In contrast, collecting physical evidence on-site, interrogating witnesses immediately, and taking photographs are actions that typically occur after this initial evaluation. They are critical components of the overall investigation but do not specifically characterize the walk-through phase.
