What is the outer perimeter of a crime scene commonly referred to as?

The outer perimeter of a crime scene is commonly referred to as the crime scene itself. This designation emphasizes the entire area that has been designated for investigation and encompasses all the evidence, potential witnesses, and the overall context of the incident being investigated.

Within this perimeter, various focused areas of interest may exist, such as where specific events occurred or where physical evidence can be found, but the crime scene as a whole represents the broader area of relevance to law enforcement and investigative work. This term is crucial for clarity in communication among law enforcement personnel, as it ensures everyone understands the full scope of the area being examined in relation to a criminal event.

While the other options mention specific concepts, they do not accurately capture the definition of the outer perimeter as generally understood in crime scene terminology.
