Securing the crime scene is crucial to prevent contamination or loss of evidence and to ensure the safety of everyone involved.
The primary goal of the preliminary investigation is to identify and preserve evidence that may be crucial for solving the crime.
Conducting a canvass helps investigators locate witnesses who may have seen or heard something relevant to the crime.
Building rapport and using open-ended questions encourage witnesses to provide detailed and accurate information without feeling pressured or influenced.
Proper documentation involves taking photographs and labeling evidence at the scene to ensure accurate and reliable records for the investigation and any subsequent legal proceedings.
