Scientific Foundations For The Reconstruction Of The Crime Scene

While researchers are never sure what really happened at the crime scene, if they have used scientific principles and their reconstruction experience, they can play a valuable role in explaining the crime and seeing justice done. Bullet path techniques can be used to supplement the analysis of the blood stain pattern during the crime scene reconstruction. By following the path or trajectory of the bullet, one can determine the position of the victim’s body at the time of the shot or determine the impact angle. Bullet path analysis can also help determine the position of the shooter and the distance to a target. For example, by recording trajectories, our scientists can follow the path or trajectory of a bullet in an attempt to locate the source of the uptake. Blood stain pattern analysis is used to determine the direction and rate of blood loss at a crime scene.

Each of these types of tests can be useful for specific parts of a criminal investigation. In any case, such investigations are valuable from time to time in committing a crime. The rebuilding of the crime scene depends on the ability to report the facts on the ground, the logical ability to look at the physical evidence, and the use of ways to deal with the hypothesis plans. While crime scene investigators must draw logical conclusions based on evidence and observation and forensic evidence results, they must be impartial and objective at all times.

“The reconstruction course of Gary and Iris Graff at the crime scene was an incredible learning experience. The knowledge and experience that Gary and Iris brought to class was invaluable and their focus on scientific methodology and objective fact-based analysis should be a model for all crime scene analysis training. The legal medical death investigation includes the research processes, protocols and techniques involved in determining the cause, mechanism and form of death of a person. A death investigation team may include personal injury expert witness la mesa california experts such as death investigators, police, detectives, forensic physicians, pathologists, forensic entomologists, paramedics, forensic anthropologists and forensic dentists. This chapter begins with a study of Glenn Ford’s conviction and exemption and explains how inadequate crime scene reconstruction played an important role in Ford’s wrongful conviction. The chapter also describes the basis of crime scene reconstruction and thoroughly explains the correct use of deductive reasoning and the scientific method.

After evidence has been identified, collected and analyzed, the crime scene investigator can hypothesize what happened on the spot. Plan, communicate and coordinate: Before collecting evidence, investigators must first develop a theory of the type of crime that has occurred. Knowing the type of crime, investigators can anticipate evidence that may be present.

An order is given to the person in question, the suspect, the witness or any other person to restore the opportunity created by the crime scene or the physical evidence depending on their understanding of the crime. This technology will have a major impact on helping the jury make honest statements. Currently, most juries are shown a crime scene by means of still images.

Although the cause of death was clear from the start, it had to be clarified whether or not the arrow had been shot as needed. The ballistic investigation into the seized weapon and the reconstruction of the crime was absolutely essential to provide convincing evidence to convict the perpetrators of the murder. The hypothesis consolidates all recent conversations about crime scene preparation with its physical evidence and information from examiners about the value and use of legal evidence techniques. Physical evidence that occurs as a result of crime and is found at the crime scene to be investigated with regard to recreation will be design evidence, evidence for shooting investigation and serological evidence.
