What does "chain of custody" refer to in forensics?

The term "chain of custody" is fundamental in forensics because it refers to the process of maintaining and documenting the handling of evidence from the moment it is collected until it is presented in court. This process is crucial for ensuring that the evidence remains intact, unaltered, and credible throughout the investigation and legal proceedings.

When evidence is collected at a crime scene, it must be carefully tracked to account for every person who touches or handles it, along with detailed records of when and how it was accessed. This documentation helps to establish the authority and integrity of the evidence, which is critical when it comes to its admissibility in court. If there are lapses or gaps in the chain of custody, it may cast doubts on the evidence's reliability, potentially compromising the entire case.

Understanding this concept is vital for anyone involved in forensic science, as it underscores the importance of preserving the integrity of evidence, which is essential for achieving justice and upholding the legal process.
