The reconstruction of the crime scene is the process of determining the order of events over what happened during and after a crime.
In particular, the crime scene analysis is carried out during the initial stages of the investigation, during the investigation and even during the award process.

Reconstruction includes thinking and consolidating all insightful data with research into physical evidence and translation formed in a sensible clarification of the crime and related occasions. Justification, cautious perception and impressive experience, both in investigating the crime scene and in legally evaluating physical evidence, are essential for legitimate understanding, investigation and ultimately crime scene reconstruction.
