What must be documented in the case file to verify a latent print examination?

• A. The number of impressions examined, the date, and the examiner's signature.
• B. Weather data.
• C. The camera's shutter speed.
• D. The suspect's name.

Answer: (A)

In latent print examination, verification hinges on clear, accountable documentation of what was done. The essential items to record are the number of impressions examined, the date the examination occurred, and the examiner’s signature.

Documenting the number of impressions examined shows exactly how many prints were considered, preventing selective reporting and supporting transparency. Recording the date anchors the work in time for the case timeline and any audits or reviews. The examiner’s signature provides attribution and accountability, confirming who performed the analysis and stands behind the conclusions. Together, these elements make the examination verifiable by others and support the integrity of the process.

Details like weather data, camera shutter speed, or the suspect’s name aren’t part of verifying the examination itself. Weather data isn’t about the interpretive analysis, shutter speed relates to photographic capture rather than the analytical conclusions, and the suspect’s name is case information rather than verification of the latent print assessment.
