Let us chat about Crime Scene Processing.

Crime scene diagrams can become complex drawings when out in the field due to the lack of buildings, structures, walls, and other fixed objects. The challenges to crime scene technicians happen when the lack of flexibility and versatility is present. The technician must be versatile in their ability when processing crime scenes. It is so important to be able to be flexible; one must think freely when processing crime scenes.

Tunnel vision is the main culprit in missing, lost, or unidentified evidence at crime scenes. Overanalyzing a crime scene can detour an investigator from seeing the obvious. Being fixed on a particular object, or processing a scene based on bias or speculation of what may have happened, can result in pieces of evidence or for that matter, the entire investigation, being based on something that was entirely unfounded.

When processing a scene, the technician should start a systematic approach to documenting the scene and the evidence. Notes are essential to process the scene correctly and thoroughly. The technician should be consistent in the mechanics of processing the scene. And do not forget to look above, below, and surrounding areas of the scene.


It is best for the technician not to allow obvious or pre-labeled evidence to become the focus of the scene. It is best to continue to search the entire area. The technician should consider all foreign objects and materials as potential crucial evidence.

Next month, I will cover a few essentials you should know when creating crime scene diagrams.

Take care.
