What is the function of crime scene investigations?

The function of crime scene investigations primarily centers around examining and collecting evidence from crime scenes. This process is critical because the evidence gathered can provide crucial insights into the events surrounding a crime, help establish timelines, and identify suspects. A well-conducted investigation involves the meticulous collection, preservation, and documentation of physical evidence, such as fingerprints, DNA, and any other relevant materials that can contribute to solving the case.

While interviewing witnesses and managing crowd control are important aspects of law enforcement operations during an investigation, they do not directly pertain to the core function of crime scene investigations, which is focused on evidence collection. Arresting suspects at the scene is also a distinct activity that falls outside the primary focus of crime scene investigations. The overall goal is to ensure that the integrity of the evidence is maintained, allowing for a thorough analysis that can support future legal proceedings.
