What is the primary purpose of the crime scene investigator's training described in the material?

• A. To secure and analyze physical evidence to help solve the case
• B. To interrogate suspects
• C. To obtain confessions
• D. To determine the guilt of suspects

Answer: (A)

The main goal of crime scene investigator training is to secure and analyze physical evidence to help solve the case. This training teaches how to recognize, collect, preserve, and document evidence in a way that prevents contamination and maintains a clear chain of custody. It also covers how to photograph, measure, sketch, and package items properly, and how to determine what should be sent to the lab for analysis. By applying these methods, investigators can reconstruct events at the scene and provide objective findings that support the investigation and any legal proceedings. Interrogating suspects, obtaining confessions, or deciding guilt are tasks outside the primary scope of scene processing; those steps involve interviews and court decisions, not the physical evidence work done at the scene.
