With the arrival of the first law enforcement officer at a crime scene, there are strict procedurals guidelines. The first officer to arrive at a crime scene tries to detain anyone that could be a witness/suspect. It is the responsibility of this officer to secure the crime scene to keep the crime scene from becoming contaminated and the loss of evidence.
With the arrival of the investigator that will take charge of the crime scene, the officer will detail all information acquired from possible witness or suspects. The investigator will document the crime scene with pictures, sketches, notes and even video of the evidence and surrounding area. After the walk through, the investigator begins formulating a theory of the crime focusing on the progressions of events to include locations and positions of those present during the crime.
