During a search, why should one avoid starting from the center?

Starting a search from the center can significantly increase the risk of stepping on evidence. When a team begins in the middle of an area and radiates outward, there is a higher likelihood of disturbing or obscuring important physical evidence that could be crucial for an investigation. Evidence can be fragile and easily displaced; hence, it is vital to ensure that the outer edges are thoroughly searched first before moving inward. This approach minimizes the chance of inadvertently compromising potential evidence that should remain undisturbed for analysis. By following a systematic search pattern from the edges towards the center, search teams can help ensure that all evidence is preserved and documented appropriately. This methodology also helps in establishing a clear understanding of the scene, thereby providing a more organized and efficient search.
