IAI Crime Scene Investigation Practice Test

The primary role of a Crime Scene Investigator in forensic science is centered on the crucial aspects of recognizing, identifying, collecting, and preserving evidence. This process is fundamental to the integrity of any criminal investigation, as the evidence collected at a crime scene needs to be properly handled to maintain its chain of custody and ensure its reliability in legal proceedings.

A Crime Scene Investigator must be trained to meticulously document the scene, understand the importance of various types of evidence—such as biological, physical, and trace evidence—and use proper techniques and tools to collect samples without contamination or degradation. This foundational work impacts the entire investigation and can determine the outcome of legal cases, making it imperative for Crime Scene Investigators to adhere to best practices when it comes to evidence management.

While conducting interviews with suspects, filing reports, and testifying in court are also important aspects of a criminal investigation, they are not the primary focus or responsibilities of the Crime Scene Investigator. Rather, these tasks often fall under the purview of other specialized law enforcement personnel and legal professionals in the justice system.
