Decision support and second opinion. Not a casework decision-maker. Your own validated SOP always governs.
A technique applied out of order can consume, contaminate or obscure the material a later discipline needs. The loss is rarely visible at the bench and cannot be undone once the exhibit has been treated.
Guidance sits across manuals, review literature, source books and local protocols. Reconciling fingermark development with DNA, trace, documents and digital recovery is left to individual judgement under time pressure.
Few practitioners can hold the full multidisciplinary picture for every substrate and case type. Unusual exhibits are exactly where a considered second opinion is hardest to obtain quickly.
Substrate, condition, contaminants, what is being sought, what the case requires. The response places fingermark development correctly within the wider recovery order and cites the literature behind each step.
The negative guidance is the part practitioners ask for first: what not to do on this exhibit, and what it would cost downstream.
Polyethylene carrier bag, recovered dry from an indoor scene. Fingermarks and DNA both sought. Handles handled by multiple persons; possible drug residue inside.
Substrate and condition, how it was recovered, what is being sought, and any constraints the case imposes. Plain language, as you would brief a colleague.
An ordered cross-discipline treatment plan with fingermark development placed correctly, each step referenced to the corpus, plus the contra-indications for that exhibit.
You remain the decision-maker. The output is a second opinion to weigh against your laboratory's validated procedures, accreditation scope and available capability.
Nothing is generated from open web material. The knowledge base is assembled from accredited forensic literature and ratified by named specialists, and every step returned carries its citation so it can be checked at the bench.
Fingermark Visualisation Manual, 2nd edition (2022), as the accredited basis for development sequences.
Interpol Review of Fingermarks and Other Body Fluids (Bécue, Champod and colleagues), used as the anchoring review of the field's evidence base.
Checked against the Fingerprint Source Book v3.0 to reconcile terminology, technique coverage and substrate guidance.
Reviewed with specialists from the European Division of the IAI and university forensic departments. Ratification is ongoing; the product remains in validation and is not offered for casework use.
Fingermark and evidence examiners who need a sober second opinion on an unfamiliar substrate or a competing-priorities exhibit, before the first treatment is applied.
Lab leads and quality managers using a common reference for triage discussions, training, and consistency of sequencing decisions across teams and shifts.
Universities, professional bodies and national units contributing review, curriculum use, or validation studies as the corpus is extended across disciplines.
One message when FingerprintAI opens to practitioners, with the scope of the first release and the disciplines covered.
