Which of the following is NOT a responsibility of a crime-scene investigator?

A crime-scene investigator primarily focuses on the physical aspects of a crime scene, which include recognizing, documenting, and preserving evidence found at that location. Recognizing evidence involves being trained to identify various types of physical clues that may be present, such as fingerprints, fibers, or biological evidence. Documenting evidence includes photographing the scene, creating sketches, and taking detailed notes to ensure the evidence is recorded accurately. Preserving evidence is crucial as well, as it prevents contamination and maintains the integrity of the evidence for analysis.

Interviewing suspects, while an important aspect of criminal investigations, is typically not within the purview of a crime-scene investigator. This task is generally conducted by law enforcement officers or detectives who are trained in interrogation techniques, rather than the personnel focused on collecting and processing physical evidence at the scene. By understanding the distinct roles in a criminal investigation, it highlights the specific responsibilities attributed to crime-scene investigators.
