Randomized trial evaluates fingerprint persistence on beverage containers, indicating higher recovery rates in full containers.
Key Points
This research aims to explore how the liquid content in beverage containers affects the detectability and persistence of latent fingerprints.
Controlled experiments on five beverage container types (PET bottles, glass bottles, aluminum cans) across three liquid levels (full, half-full, empty)
Utilized a standard cyanoacrylate fuming protocol to evaluate fingerprint recovery
Assessed fingerprint persistence over five different storage intervals (1 day to 3 months)
Full containers yielded the highest fingerprint comparison suitability rate at 80%
