Why is chain of custody crucial for physical evidence and what can break it?

• A. It ensures the integrity and authenticity of evidence from collection to presentation; breaks include gaps in documentation, tampering, or unauthorized handling.
• B. It only matters for chain-of-title.
• C. It's only required for digital evidence.
• D. Breaks occur only if vendor loses chain.

Answer: (C)

Preserving integrity and admissibility hinges on an unbroken, well-documented trail of custody from collection to presentation. This means each transfer of the physical evidence is recorded with who handled it, when, where, and for what reason, and it is securely packaged and sealed so its condition can be verified at every step. When the chain is intact, the evidence is trusted to be the same item in the same condition as when it was collected; any break—gaps in documentation, tampering, or unauthorized handling—undermines authenticity and can lead to challenges or exclusion in court. While digital evidence also requires careful custody, the principle for physical evidence is about maintaining a credible, verifiable trail through every stage of its life. It's not about chain of title or vendor issues; breaks can occur from any lapse in proper documentation, seals, or authorized access.
