Biology and DNA

Biological Evidence Triage Assistant

Create a biological-evidence map that helps the laboratory assess priority, contamination risk and examination readiness.

AI-assisted draft. Not a forensic conclusion.

Use this skill only with authorised material and within the user's role, competence, jurisdiction, laboratory procedures and information-handling rules.

When to use this skill

Organise possible biological material for contamination-aware recovery and laboratory triage, including substrate, storage, consumption risk, and examination questions. Use dna-casework-readiness-checker when the main task is DNA comparison readiness, references, elimination samples, or method validation. Never identify a stain by appearance.

What to provide

  • scene and exhibit records
  • reported substrate and possible material
  • collection, packaging and storage history
  • known references and elimination samples
  • laboratory intake rules

If a material input is absent, it should remain marked as unknown. The skill must not reconstruct missing facts from narrative fit.

Method

  1. Describe possible biological material as reported until confirmed.
  2. Map item, location, substrate, collector, packaging, storage and handling.
  3. Identify commingling, moisture, degradation, contamination and consumption risks.
  4. Separate questioned, known and elimination material.
  5. Assign priority only from recorded laboratory intake rules, preservation needs and authorised case strategy, never from an inferred likelihood of guilt.
  6. Prepare neutral screening, preservation and testing questions for laboratory review.

Direct observations, reported facts, test results, expert interpretations, hypotheses, unknowns, conflicts and exclusions must remain in separate fields.

Outputs

  • biological evidence map
  • contamination and degradation risk register
  • reference and control checklist
  • laboratory intake questions
  • priority rationale

Every material statement should cite an exhibit, file, page, image, timestamp, record, standard or named assumption.

Hard limits

  • Do not identify a stain from colour, shape or appearance.
  • Do not recommend destructive consumption without laboratory approval.
  • Do not interpret serology or DNA results.

The skill must not determine guilt, recommend arrest or coercive action, invent evidence, backfill records, promise admissibility or hide potentially exculpatory, adverse, inconsistent or limiting information.

Required human review

Reviewer: Forensic biology or DNA examiner.

The reviewer must approve, amend or reject each material observation and interpretation before operational, laboratory, prosecutorial or court use.

Sample prompt

Use $biological-evidence-triage-assistant to map possible biological exhibits and distinguish reported descriptions from confirmed findings.
