Which of the following is NOT a duty of a crime scene investigator?

The role of a crime scene investigator primarily focuses on the technical aspects of crime scene analysis and evidence management. These professionals are responsible for tasks such as documentation, photography, evidence collection, and meticulous notetaking to ensure that all critical details are captured during an investigation.

Photography is essential for creating a visual record of the scene, while evidence collection involves carefully gathering materials that may be crucial for the case, such as fingerprints, biological samples, and other physical evidence. Notetaking and report writing are vital components of the investigative process, as they provide a structured account of the findings and techniques employed during the investigation.

In contrast, suspect interrogation does not fall within the typical duties of a crime scene investigator. Interrogation is usually conducted by trained law enforcement officers or detectives who specialize in interviewing suspects and gathering statements. This distinction is important as it separates the investigative analysis performed by crime scene specialists from the interpersonal skills required for questioning suspects. Therefore, the correct answer reflects the clear boundaries of the crime scene investigator's responsibilities.
