What is the chain of custody?

• A. The legal ownership of evidence by the initial collector.
• B. A system for tracking the chain of custody is unnecessary in most cases.
• C. Documentation of all transfers of evidence from collection to presentation to ensure integrity.
• D. The sequence of steps in an investigation.

Answer: (C)

Chain of custody is the documented, unbroken record of every person who has handled evidence from the moment it’s collected through every transfer, storage, analysis, and finally presentation in court. The key idea is to log each transfer and how the evidence was kept so its integrity and authenticity can be trusted. This means noting who collected it, when and where, every person who possessed it, how it was stored (for example, sealed or refrigerated), any analyses performed, and any changes in its condition. A gap in the log or an untracked transfer can cast doubt on the evidence’s validity, which is why thorough documentation of all transfers to ensure integrity is essential. The other options miss the point: ownership is not what the record tracks, and the chain of custody is not merely the sequence of investigative steps but the clear trail of who handled the evidence and how it was preserved.
