Criminal Investigation Management Training Course

Participants can make and record sound early decisions that protect investigative opportunities.

• First-report assessment captures immediate risks, safeguarding concerns and evidential opportunities
• Golden-hour actions prioritise victims, scenes, suspects, witnesses and volatile material
• Scene preservation controls protect physical, digital and documentary evidence
• Initial accounts recorded without contaminating later formal witness interviews
• Triage criteria distinguish urgent enquiries from actions requiring further authority
• Early case strategy identifies likely complexity, specialist support and review points

Participants can build a proportionate investigation plan that tests competing explanations.

• Hypothesis testing separates reasonable lines of enquiry from unsupported assumptions
• The ABC model frames allegations, background and corroboration requirements
• Investigative plans assign actions, owners, deadlines, dependencies and review triggers
• Alternative suspect, accident and fabrication hypotheses receive documented consideration
• Action prioritisation uses evidential value, risk, urgency and likelihood of loss
• Plan revisions preserve an auditable record of changed investigative direction

Participants can construct an evidence matrix that exposes strengths, gaps and corroboration needs.

• Evidence matrices connect each allegation to required facts and sources
• Direct, circumstantial, real and documentary evidence classified for case analysis
• Corroboration plans test key assertions through independent witnesses, records or forensics
• Case theory states how evidence supports guilt and alternative explanations
• Evidence gap analysis identifies missing proof, weak links and priority actions
• Chronologies organise events, disclosures, decisions and evidential developments accurately

Participants can create a witness strategy that protects welfare and evidence quality.

• Witness assessment considers vulnerability, intimidation, communication needs and evidential value
• Achieving Best Evidence principles guide planning for vulnerable and intimidated witnesses
• Special-measures requests link witness needs to participation and evidential quality
• Witness strategy separates welfare support from evidential questioning responsibilities
• Contact plans prevent unnecessary repeat interviews and avoid witness contamination
• Intermediaries, interpreters and appropriate adults selected through documented needs assessments

Participants can prepare structured, lawful and purposeful investigative interviews using PEACE.

• PEACE stages structure preparation, engagement, account, closure and evaluation
• Interview objectives distinguish information needs from assumptions about expected answers
• Topic plans sequence rapport, free recall, clarification and challenge appropriately
• Disclosure strategy determines what evidence is put and when
• Risk assessments address welfare, safeguarding, security and interview contamination
• Interview plans record exhibits, timings, attendees, breaks and communication adjustments

Participants can plan witness interviews that obtain detailed, reliable and uncontaminated accounts.

• Cognitive interview techniques support context reinstatement and uninterrupted free recall
• Open questions elicit accounts without introducing facts, assumptions or suggested answers
• TED questioning uses tell, explain and describe prompts effectively
• Focused prompts clarify sequence, sensory detail, source knowledge and uncertainty
• Witness memory limitations explained through encoding, retention, retrieval and post-event information
• Closure confirms accuracy, explains next steps and records further contact arrangements

Participants can adapt interview planning for children and vulnerable adults while protecting reliability.

• Ground rules establish truthfulness, uncertainty responses and correction of interviewer mistakes
• Rapport-building avoids promises, inducements and discussion of disputed events
• Developmental capacity informs language, pacing, sequencing and communication aids
• Registered intermediaries advise on communication needs and question formulation
• Achieving Best Evidence planning addresses visually recorded interviews and special measures
• Repeated interviews require clear justification, safeguards and recorded supervisory approval

Participants can plan suspect interviews that fairly test accounts against available evidence.

• Suspect interview objectives test accounts, explanations, defences and evidential inconsistencies
• Account-based interviewing seeks explanation before confrontation with incriminating material
• Disclosure packages distinguish strategic questioning material from material requiring later disclosure
• Challenge sequences test contradictions using chronology, detail and corroborative evidence
• Silence, denials and prepared statements assessed without adverse assumptions
• Interview evaluation identifies further enquiries, evidential admissions and disclosure implications

Participants can manage identification evidence using controls that reduce suggestion and contamination.

• Description-first protocols record witness recollection before suspect exposure or image viewing
• Sequential identification procedures reduce relative judgement and administrator influence
• Blind administration prevents investigators from signalling expected identification outcomes
• Confidence statements capture witness certainty immediately after an identification decision
• Contamination risks include co-witness discussion, media exposure and investigator feedback
• Identification records document procedure, images, instructions, responses and anomalies

Participants can preserve, package and account for physical exhibits through defensible continuity records.

• Exhibit registers assign unique references, descriptions, locations and responsible custodians
• Continuity records document every transfer, examination, storage movement and return
• Packaging choices protect biological, trace, fragile and hazardous material
• Contamination controls separate exhibits, use protective equipment and document exceptions
• Forensic submissions state agreed questions rather than seeking unsupported conclusions
• Quality checks reconcile exhibit registers against case files and forensic reports

Participants can direct the preservation and examination of digital evidence without compromising integrity.

• Digital evidence sources include devices, cloud services, CCTV and communications platforms
• ISO/IEC 27037 principles guide identification, collection, acquisition and preservation
• Volatile data risks require prompt decisions on isolation, capture and specialist support
• Hash values verify forensic image integrity during storage and subsequent review
• Examination requests specify dates, users, artefacts, search terms and evidential questions
• Digital material reviews distinguish relevant evidence from privacy-sensitive unrelated data

Participants can plan reliable acquisition and analysis of financial, documentary and open-source material.

• Document provenance assessed through source, creation, custody, metadata and alteration indicators
• Financial transaction analysis links accounts, entities, dates, values and counterparties
• Link charts reveal associations, communications, transfers and unexplained relationship patterns
• Open-source intelligence preserves URLs, timestamps, captures and collection methodology
• Records requests define date ranges, identifiers, formats and legal authority
• Analytical products separate verified fact, inference, intelligence and unresolved questions

Participants can identify, record, review and disclose material using defensible controls.

• Disclosure schedules record unused material, descriptions, locations and reviewer decisions
• Reasonable lines of enquiry include material assisting or undermining either case
• Materiality assessments distinguish relevance, sensitivity, privilege and disclosure obligations
• Retention plans protect notes, drafts, recordings and negative enquiry results
• Disclosure decision logs record rationale, legal advice and review dates
• Sensitive material handling restricts access while preserving accountability and audit trails

Participants can recognise cognitive bias and apply safeguards to improve investigative decisions.

• Confirmation bias distorts evidence selection, hypothesis testing and interview interpretation
• The red-team review challenges assumptions, missed alternatives and weak inferences
• Disclosure obligations counteract tunnel vision through active consideration of contrary material
• Ethical decision records identify authority, necessity, proportionality and foreseeable harm
• Conflict declarations address personal relationships, prior involvement and perceived impartiality
• Supervisor reviews test reasoning quality rather than merely action completion

Participants can conduct structured case reviews that maintain direction, quality and accountability.

• Milestone reviews reassess hypotheses, risks, evidence gaps and resource requirements
• The 5WH method tests who, what, when, where, why and how
• Supervisory review notes record decisions, challenge, actions and follow-up dates
• Escalation thresholds address safeguarding risk, media interest, complexity and public confidence
• Case conferences coordinate investigators, prosecutors, analysts and specialist advisers
• Closure decisions document evidential sufficiency, outstanding material and victim communication

Participants can assemble a clear, indexed and review-ready investigation case file.
