What are typical stages in a forensic investigation?

• A. Only evidence collection and analysis
• B. Crime scene processing and evidence collection
• C. Interviewing witnesses only
• D. Document examination and reporting only

Answer: (B)

In a forensic investigation, crime scene processing and evidence collection are critical stages that ensure the integrity and completeness of the investigative process. Crime scene processing involves securing the scene, documenting it through photographs and sketches, and ensuring that all potential evidence is preserved and properly handled to avoid contamination or loss. This initial step sets the foundation for the entire investigation, as it is crucial that all relevant evidence is captured accurately. Following crime scene processing, evidence collection involves gathering physical items that could contribute to the investigation, such as fingerprints, DNA samples, weapons, or any other materials that might provide leads or insights into the crime. Proper techniques in both processing and collection are vital since the quality and reliability of this evidence can significantly impact the outcome of the investigation. The other choices focus on specific components of the broader investigation process. While interviewing witnesses and document examination are essential, they do not encompass the critical first steps that lay the groundwork for a forensic investigation, making them insufficient as standalone stages. Thus, the stages of crime scene processing and evidence collection represent a comprehensive approach that is integral to effective forensic investigation.
