Securing the Scene focuses on creating a perimeter that covers every place where evidence could be, including areas where items or traces might be hidden or moved. Making the scene large enough to include flight paths or escape routes is essential because suspects may have fled through those routes, taking or dropping evidence along the way, and investigators need the full context to protect and identify all potential evidence. This approach helps preserve integrity, controls who can access the area, and supports thorough searches and accurate documentation. Interviews and other actions are important, but they don’t replace the need for a properly defined, expansive perimeter. Removing evidence or clearing the scene prematurely would undermine the investigation and compromise evidence integrity.
