Evidence Marking is a systematic process used in law enforcement and forensic science to label and document physical evidence collected from a crime scene. Each piece of evidence is assigned a unique identifier, such as a number or barcode, which helps track its chain of custody and ensures its integrity throughout the investigation and legal proceedings. Proper Evidence Marking includes details like the date, time, location, and the person who collected the evidence. This information is crucial for maintaining the reliability of the evidence in court, as it helps establish its authenticity and relevance to the case being prosecuted.
