Chain of custody is the documented record of who handled the evidence, when, where, and under what conditions. This record protects the evidence’s integrity by ensuring it remains unaltered from collection to court, preventing tampering, substitution, or contamination. A continuous trail means each transfer is logged with dates, times, locations, and signatures, the item is securely sealed and stored, and every custodian takes responsibility for it. This supports admissibility because it helps prove the item presented in court is the same one that was collected and has not been corrupted. If the chain is broken or poorly documented, questions about authenticity and integrity can lead to exclusion or diminished weight. For example, a bloody garment with proper seals, labeling, and a clear transfer log is far more admissible than one with gaps in custody. The other descriptions describe budgeting, witness lists, or command structure, which do not address how evidence is tracked and preserved.
