What is the first action in a Walk Through at a crime scene?

• A. Interviews witnesses.
• B. Preliminary scene survey.
• C. Final sketching.
• D. Criminal profiling.

Answer: (B)

The walk-through begins with a preliminary scene survey. This quick, broad look focuses on understanding the overall layout of the area, identifying boundaries, entry and exit points, lighting conditions, hazards, and the locations of major features that could hold evidence. By surveying first, investigators build a mental map of the scene and determine how evidence is likely distributed, which informs where and how to document, photograph, and later collect items. This initial survey sets up the rest of the process: once the scene is understood in broad terms, you can plan precise documentation, establish search patterns, and decide what needs to be photographed or sketched. Interviews with witnesses or suspects, final sketches, and deeper analyses come after the scene’s basic layout and conditions are noted. Criminal profiling, while part of some investigations, is not a step in the walk-through itself.
