Which of the following is NOT one of the three main entities of crime scene processing?

• A. Initial responders
• B. Crime scene technicians
• C. Investigators
• D. Dispatchers

Answer: (D)

In crime scene processing, the on-scene workflow is driven by three roles: the initial responders who arrive first, secure and protect the area; the crime scene technicians who document, collect, and preserve evidence; and the investigators who oversee the scene, plan the approach, and interpret findings. The question asks which role does not belong in that trio. Dispatchers are essential for getting resources to the scene and maintaining communication, but they operate remotely and aren’t part of the on-site processing steps. They coordinate, not perform the on-scene documentation, collection, or investigative actions. So, dispatchers are not one of the three main entities of crime scene processing, making them the correct choice.
