When collecting plastic prints, which action is appropriate?

• A. Photograph and collect the entire item
• B. Ignore the item
• C. Break the object to preserve print
• D. Only use powder without photography

Answer: (A)

Photographing and collecting the entire item preserves and documents the print without destroying evidence. On plastic surfaces, the print’s location, orientation, and surrounding details matter for later analysis, so capturing high-quality photos first ensures these details aren’t lost. Collecting the whole object maintains the chain of custody and allows the lab to process the print without contamination or damage to the item. Breaking the object would destroy the print and compromise the evidence. Ignoring the item or relying only on powder without documenting the scene misses critical context and can hinder later verification.
