Which individuals typically have the most limited access to a crime scene?

Individuals who are part of the general public typically have the most limited access to a crime scene. This restriction is primarily in place to preserve the integrity of the investigation. The presence of unauthorized individuals can compromise evidence, interfere with law enforcement procedures, or even lead to contamination of the scene.

While medical personnel and investigators have roles that may necessitate access to the crime scene, they are usually there under specific circumstances or protocols. Authorized personnel, such as law enforcement officers and crime scene investigators, are granted access to perform their duties effectively, ensuring that evidence is collected and preserved properly. Thus, the general public is kept at a distance to maintain the chain of custody and the overall safety of the investigation.
