What is required when collecting evidence to maintain integrity?

• A. Documentation of handling
• B. Chain of custody only
• C. Documentation of handling, chain of custody, labeling, and storage
• D. Witness statements only

Answer: (C)

Maintaining the integrity of evidence comes from a comprehensive approach that covers every step from collection to storage. Documenting how the item is handled records who touched it and under what conditions, which helps prevent contamination or substitution. The chain of custody provides a continuous, verifiable timeline of every transfer or examination, showing that the evidence remained untampered with since collection. Labeling gives the item a unique identity and links it to the case, preventing mix-ups with other materials. Proper storage preserves the evidence’s condition and protects it from environmental damage, loss, or tampering. When these elements are combined, the evidence remains authentic, admissible, and reliable. Relying on just one aspect, like the chain of custody alone, creates gaps where contamination, misidentification, or tampering could go unnoticed. Witness statements may support the case, but they do not substitute for the documentation, tracking, and preservation necessary to maintain the evidence’s integrity.
