What is the primary purpose of a preliminary investigation?

The primary purpose of a preliminary investigation is to gather evidence and secure the scene. This phase is critical as it establishes the foundation for any further action that may follow. By collecting evidence immediately after a crime is reported, law enforcement officers can ensure that vital information is preserved and not lost. This includes taking photographs, collecting physical evidence, and securing witness statements, all of which contribute to building a case.

Securing the scene is equally important to prevent contamination of evidence and to maintain the integrity of the investigation. This initial gathering of evidence can significantly influence the direction of the investigation, helping determine if a crime has been committed, the nature of that crime, and identifying potential suspects.

While arresting the suspect and charging them with a crime are important components of the law enforcement process, these actions typically occur following a thorough preliminary investigation, which lays the groundwork necessary for such steps. Similarly, while providing a report for the court is essential, it comes later in the investigative process and relies on the evidence and findings collected during the preliminary investigation.
