What are the criminal investigator's functions in a criminal case? (3 items)

• A. Administrative, Legislative, Judicial
• B. Forensic, Interrogation, Prosecution
• C. Operational, Strategic, Tactical
• D. Investigative, Judicial, Post-Judicial

Answer: (D)

Criminal investigator functions span three stages: investigative, judicial, and post-judicial. In the investigative stage, the focus is on gathering facts—watching for evidence, interviewing witnesses, collecting and preserving physical items, and reconstructing what happened to build a solid case record. In the judicial stage, the investigator supports the court process by organizing the evidence for presentation, obtaining warrants or subpoenas as needed, and providing testimony and documentation that uphold chain of custody and evidentiary standards. In the post-judicial stage, the investigator wraps up the case with final reports, ensuring proper disposition of the investigation, maintaining records, and handling any follow-ups related to victims, witnesses, or future related matters. Other groupings don’t fit as cleanly because they either describe techniques or roles outside the investigator’s duties (forensic work or prosecution), or they refer to broad planning terms (operational, strategic, tactical) that aren’t the standard way to categorize the investigator’s core functions.
