Crime Scene Analysis (CSI)
In 1920, the French criminologist Edmond Locard formulated the Exchange Theory, which states that “the person or persons present at the scene of a crime almost always leave something of themselves at the scene and take something away from the scene.”
“The examination of the crime scene involves a complex set of activities carried out by the judicial police, the technical consultants for the Public Prosecutor and the defense, together with the technical consultants and private investigators. These activities are technical and scientific in nature and are conducted at the locus commissi delicti (crime scene), both immediately upon discovery of the crime and during any subsequent inspections. The goal is to isolate, describe, and analyze the scene, as well as to search for, examine, and collect any traces found there.”
Given this, the intervention of a few experts is necessary, such as the professionals working at the investigative agency “Argo”, who promptly, aseptically, and above all objectively, carry out a meticulous site inspection. This allows for the precise collection of all material elements that characterize the criminal act, immediately after its discovery.
Argo employs forensic technical consultants who can carry out or verify technical and laboratory examinations on biological evidence, conduct instrumental investigations on blood stains or substances of various natures, and finally perform complete ballistic examinations.
Collection and Preservation of Traces
One of the most delicate phases during an inspection is precisely the collection of traces, biological and otherwise, which can be used to:
- Link a suspect to the victim or the crime scene;
- Establish the dynamics of the crime (criminodynamics);
- Confirm the testimony of a witness;
- Prove that a crime was committed.
