Crime scene investigation primarily involves the documentation and analysis of evidence, which is critical for reconstructing the events surrounding a crime. This process starts at the very moment the crime scene is accessed, where investigators meticulously document everything through photography, sketching, and taking detailed notes. This documentation ensures that every aspect of the scene is recorded so that no evidence is overlooked, and it aids in presenting the findings in court.

Following the documentation phase, investigators analyze the collected evidence—such as fingerprints, DNA, weapons, and other physical items—using scientific methods. This analysis helps establish connections between the crime, the suspect, and the victim, forming a crucial link in the investigative process.

While interrogation of suspects, witness interviews, and surveillance operations are all important aspects of criminal investigations, they occur after the initial crime scene investigation. These steps complement the foundation laid by thorough documentation and analysis of evidence, ensuring a comprehensive approach to solving the case.
