What is the purpose of documenting chain of custody in evidence handling?

• A. It provides traceability of evidence from collection to analysis
• B. It proves the suspect's guilt
• C. It replaces the need for photos
• D. It determines the time of day

Answer: (A)

Documenting chain of custody is about creating a continuous, documented trail for each piece of evidence from the moment it is collected to the moment it is analyzed. By recording who handled the item, when it was moved, where it was stored, and under what conditions, you establish traceability that the evidence has not been altered, substituted, or degraded. This transparency protects the integrity of the evidence and supports its admissibility in court, because it shows the item presented is the same one that was collected and that its handling can be reviewed at every step. It also helps investigators reconstruct what happened and identify any points where mishandling could have occurred. It’s not about proving guilt, it doesn’t replace photos, and while time stamps can be part of the record, the primary goal is maintaining a trustworthy chain of custody throughout the investigation.
