What is the objective of a preliminary investigation?

The objective of a preliminary investigation is primarily to conduct an initial investigation by the first officer on the scene. This phase is crucial because it sets the foundation for any subsequent investigative efforts. The first officer's primary responsibilities at this stage include assessing the situation, securing the scene, ensuring safety, and beginning the process of gathering information. This might involve taking initial notes, identifying witnesses, and determining if any immediate action is required, such as calling for additional support or medical assistance.

By effectively performing these initial tasks, the officer ensures that evidence is preserved and that any potential leads are followed up appropriately later in the investigation. This foundational work is essential as it can significantly influence the direction and success of the overall investigation. Although gathering evidence for court, interviewing witnesses, and initiating a criminal case are also important aspects of the investigative process, they typically occur after the preliminary investigation has established the initial facts and situation at the scene.
