The chain of custody is a fundamental concept in forensic investigations that establishes a clear and documented history of who had control of the evidence from the moment it was collected until it is presented in court. This record is crucial for ensuring the integrity and credibility of the evidence. By maintaining an unbroken chain, investigators can demonstrate that the evidence has not been tampered with, altered, or contaminated at any point during its handling.

This documentation typically includes information about everyone who has handled the evidence, along with timestamps and details about how and when the evidence was transferred. Such rigor is vital for legal proceedings, as it helps to verify that the evidence is authentic and reliable. If the chain of custody is compromised, it can lead to challenges against the admissibility of the evidence in court.

In contrast, documenting dates for forensic techniques applied, focusing solely on the locations of evidence, or detailing evidence packaging techniques do not address the critical need to prove continuity and responsibility for the evidence. These factors, while important in different respects, do not fulfill the primary role of ensuring the evidence's integrity throughout the investigation process.
