The correct answer is: Scene examination

The first step in conducting a criminal investigation is scene examination. This phase is crucial as it involves assessing the crime scene for any immediate hazards, securing the area to prevent contamination, and gathering initial observations. By thoroughly examining the scene, investigators can obtain vital information that can shape the direction of the investigation. This includes identifying potential sources of evidence, understanding the context of the incident, and documenting the condition of the scene through photographs, sketches, and notes. A comprehensive scene examination lays the foundation for subsequent steps, such as interviewing witnesses, collecting evidence, and making arrests. It ensures that all information is preserved in as close to its original state as possible, which is essential for any future legal proceedings and for establishing a factual basis for the investigation. Therefore, initiating the investigation with a meticulous scene examination is fundamental to ensuring that the entire investigative process is built on solid ground.
