What is the first step regarding evidence to ensure it remains unchanged from the scene to the point it is found?

The first step regarding evidence to ensure it remains unchanged from the scene to the point it is found is the establishment of the Evidence Chain of Custody. This practice involves the meticulous documentation of who collected the evidence, where it was collected, and how it has been handled throughout the investigation process. By maintaining a clear and detailed chain of custody, investigators ensure that the integrity of the evidence is preserved and that it can be reliably used in legal proceedings without challenges regarding its authenticity or handling.

The chain of custody serves as both a procedural safeguard and a legal requirement, detailing every individual who has handled the evidence, thus affirming its integrity and continuity from the crime scene to the courtroom. This step is crucial in demonstrating that the evidence presented is exactly as it was found and has not been tampered with or altered in any way.
