Final answer:
The practice of starting a crime scene search at the victim and working outward is not a fixed rule; investigators must evaluate each scene individually to determine where to begin. The search pattern should be systematic and maintain evidence integrity. Decisions on where to start are made based on the initial walkthrough, the crime scene's nature, and the goal of preserving the chain of custody.
Step-by-step explanation:
When conducting a crime scene search, the best practice is not to start with one fixed rule on where to begin, such as always starting with the victim and working outward. Crime scene search strategies may vary depending on the nature and extent of the area in question, the type of crime, and the initial findings of the investigation.
Generally, a crime scene examination begins with a walkthrough to assess the situation and determine the most logical and effective search pattern. This preliminary survey helps to establish the confines of the crime scene and identify potential evidence. After securing the scene, the investigator may indeed start near the victim to preserve the most critical evidence, which is often in close proximity to the victim, but this is not an absolute rule. In some situations, the search may start from the point of entry or exit or at the outer perimeter to avoid contaminating evidence closer to the victim.
Investigators should use a systematic approach, whether it's a spiral, grid, linear, or quadrant pattern, to ensure thoroughness. They must also consider the possibility of secondary crime scenes. The primary goal is to identify, preserve, and collect evidence in a manner that maintains its integrity and the chain of custody. Decisions about the search pattern should be made on a case-by-case basis with this goal in mind.
