The study of social and legal relations between various subjects of law and the knowledge of the truth in the process of considering crimes is an integral part of the professional activities of many police officers. They need knowledge not only of the procedural order of carrying out these actions, which are regulated by law but also of the psychological characteristics of the behavior of persons participating in them, evaluating the evidence obtained from these actions.
Preliminary investigation is a purposeful process, the purpose of which is the reconstruction (restoration) of a past crime event based on the traces found by the investigator in the present. This article will discuss how forensic tech tools help perform forensic video and image analysis from a crime scene.
Directions of crime scene reconstruction
There are two directions of such reconstruction.
- Reconstruction of the actual event of the crime and the objective conditions that contributed to its commission. An exhaustive understanding of the object and the objective side of the corpus delicti is the ultimate purpose of such a reconstruction. You can attain this using photogrammetry software for auto-measuring the body of the crime.
- The study of the identity of the offender in the development of the mechanism for the formation of a criminal attitude, criminal intent, and the subjective attitude of the offender to the committed act.
Such research seeks to learn everything there is to know about the crime in question, including its subjective aspects and its specific reasons. These are manifested through the criminal attitudes and criminal behavior of this person. There are some differences between the reconstruction of a crime event using forensic tech tools and the study of the offender’s identity.
Information that can be seen at a crime scene
All the information that the investigator receives can be divided into two categories.
- Material traces – objective information about the crime’s event and the offender’s identity, which can be investigated and identified by natural science methods (by the trace of hands, feet, blood, saliva, traces of cutting on the shell of a bullet, etc.).
- “Perfect traces” – information about the crime’s event and the offender’s identity, which people know and can reproduce during interrogation.
Forensic psychology primarily studies the patterns of formation, storage, and reproduction of traces of the second category.
The reconstruction of the crime event is carried out as a result of the purposeful activity of the investigator, which has its own program and differs from other types of human activity in a number of ways.
The process of cognition begins with obtaining the necessary information about the subject of research with the help of the senses. This information is subjected to logical processing using photogrammetry software, and the conclusions obtained are verified by practice.
However, the objects of sensory perception during the investigation of a crime are not the established events or acts themselves but their reflection, which remains in the minds of people and on various material objects (traces of the criminal, changes caused by his actions, etc.). As for the picture of the crime committed, it is, in all cases, recreated indirectly, and a forensic image enhancement software free helps with further analysis.
Images or video recordings obtained at a crime scene are mostly subjected to further analysis. This aims to assist and get new leads and the scene’s orientation, which is vital in the judicial proceedings. An image or video enhancement software that can perfectly help you reconstruct a crime scene is the MC2 (My Cognitech Cloud Online).
