What are the three major functions of a crime scene to achieve its objective?

The correct answer highlights the three major functions essential for effectively managing a crime scene. Overall coordination of the scene ensures that all personnel involved have a clear understanding of their roles and responsibilities, facilitating an organized response to the incident. Forensic services are crucial in collecting and preserving evidence, which provides critical information for the investigation. Investigative services focus on following leads, interviewing witnesses, and piecing together the events that led to the crime, which is vital for resolving the case and bringing perpetrators to justice. Together, these functions create a structured approach that maximizes the effectiveness of the crime scene investigation and helps achieve its primary objectives.
