What information should be recorded before photographing or sketching a crime scene?

Recording the case number, location, date and time, and officer's name is essential for establishing a clear and organized foundation for the investigation. This information provides context and ensures accurate documentation of the scene, which can be crucial for legal purposes later on. It allows investigators and the court to reference specific details about the investigation, maintain chain of custody, and validate the credibility of the crime scene documentation.

Having a structured record helps to prevent confusion and miscommunication, particularly in complex cases involving multiple officers or jurisdictions. Additionally, this information assists in correlating the time frame and geographical location of the incident with other related events or evidence that may arise during the investigation. This foundational data is critical for maintaining the integrity of the investigation process and supporting subsequent actions taken by law enforcement.
