A fingerprint examiner compares a latent print from a crime scene with an ink print from a suspect. The ACE-V methodology (Analysis, Comparison, Evaluation, Verification) is used. Which stage detects a potential decision error in the examiner's conclusion?
- A Analysis — the examiner re-examines the latent print
- B Comparison — the examiner overlays the prints
- C Verification — an independent second examiner reviews the analysis and conclusion ✓
- D Evaluation — the examiner reaches a conclusion
Explanation
The Verification stage in ACE-V involves an independent second examiner who repeats the entire ACE process without knowledge of the first examiner's conclusion (blind verification). This serves as a quality control mechanism to detect cognitive bias and technical errors. The analysis stage establishes the features of the latent print; comparison involves side-by-side comparison; evaluation leads to a conclusion (individualisation/exclusion/inconclusive). Verification is specifically the error-detection safeguard and is now considered mandatory in accredited forensic laboratories.
