Primary Functions

Conduct pre-interview case reviews by analyzing investigative files, witness statements, forensic reports and digital evidence to identify information gaps, contradictions, risk factors and lines of questioning that will advance the investigation.
Apply advanced, ethically grounded interview methodologies (e.g., cognitive interviewing, PEACE model, rapport-based techniques) to maximize accurate recall while avoiding coercion, leading questions, or any actions that could compromise legal admissibility.
Assess credibility and veracity of statements using statement analysis, cross-referencing with physical and digital evidence, and by documenting inconsistencies that require further investigation or corroboration.
Prepare, administer and document Miranda/rights advisories, ensuring suspects understand their rights and confirming voluntary, informed waivers in accordance with jurisdictional requirements.
Operate and maintain interview room audio and video recording systems; ensure continuous, tamper-evident recordings are created and archived per policy to preserve evidentiary integrity and transparency.
Create clear, comprehensive interview reports and sworn statements that summarize questions asked, answers given, non-verbal observations, and evidentiary relevance—written for use by detectives, prosecutors and court proceedings.
Serve as the departmental liaison with prosecutors, providing case briefs, witness summaries and recorded interview materials; coordinate pre-trial preparation and support to ensure interview evidence is admissible and understandable in court.
Provide courtroom testimony and expert witness statements regarding the circumstances of interviews, recording processes, statement content, and procedural compliance when required by prosecution or defense.
Work collaboratively with forensic, digital forensics, and crime scene units to align interview timelines, validate physical evidence links, and identify forensic leads that can be explored through follow-up interviewing.
Identify and refer vulnerable victims or witnesses (children, elderly, cognitive impairment, mental health concerns) to appropriate advocacy and protection services, and adapt interview approaches to minimize trauma while maximizing information quality.
Manage sensitive case information and ensure chain of custody procedures are followed for interview recordings, documentary evidence and any physical items collected in relation to the interview.
Maintain and update interrogation-related case files, logs and databases (RMS/CAD, evidence management systems) ensuring accurate, searchable records for investigative continuity and auditability.
Conduct risk assessments for interview safety, assessing potential for violence, self-harm, or flight risk, and coordinating security or medical support for high-risk interviews as needed.
Lead or contribute to multi-disciplinary investigative teams, providing interview strategy, witness development plans and prioritized lines of enquiry to optimize overall case outcomes.
Train, mentor and review work of junior interviewers and investigators; conduct quality assurance reviews of interview recordings and reports to ensure adherence to best practices and legal standards.
Develop and update departmental policies, training materials and standard operating procedures related to interviewing, recording, victim engagement and evidentiary handling.
Monitor and apply legal developments, case law and jurisdictional guidance affecting interview admissibility, interrogation techniques and evidence preservation to mitigate risk and support prosecutions.
Coordinate with intelligence and external law enforcement partners (federal, regional, international) on trans-jurisdictional interviews, extradition-related interviewing or multi-agency operations.
Support investigations involving complex modalities (e.g., organized crime, cyber-enabled offenses, terrorism, sexual offenses), tailoring interviewing approaches to case-specific dynamics and specialist evidence.
Maintain confidentiality and ethical standards around sensitive investigative material; ensure restricted dissemination of interview recordings and sensitive witness identities consistent with privacy law and investigative needs.
Conduct post-interview analysis sessions with investigative teams to evaluate information yielded, identify investigative leads, and establish follow-up tasks and timelines for case progression.
