Essay On Crime Scene Reconstruction

The popular television show, CSI: Crime Scene Investigations has been on the air for 12 years, and it has brought forth the behind-the-scenes actions of criminal investigations, even if its portrayals are not always scientifically accurate. This has caused an interest in the forensic sciences that has led most people to a skewed view of how a criminal investigation actually works. The reality of a criminal investigation is that it is generally more tedious and difficult than the theory of criminal investigation would have you believe. By examining the forensic and investigative procedures of the case of Pamela Foddrill, it is apparent that the theory of criminal investigation was not representative of the procedures concerning examination

Forensic science can be defined as the relationship between law and science; it answers the questions of how, why and who committed the crime, with the input of multiple actors. However, there are currently problems with

Homicide detectives only investigate and focus on Homicides. College educations are recommended but not required. Murder detectives collect evidence like fingerprints DNA and stuff like that. They interview suspects and witnesses who may have information for the murder. There are two types of crime scenes. The primary crime scene is where the crime scene is where the crime actually occurred. for example if a bank get robs that is the primary scene and the getaway car and the lair are the secondary scene. primary crime scenes are usually more helpful. while secondary scenes sometimes are the only thing that criminologists have to work with. For example this may be where a serial killer dumps a body. So investigators may not be able to prove where the actual murder occurred. which means they only find evidence at the secondary scene which could lead to the primary scene or prove that is where the crime happened. For example you may find a hair or a fiber at a scene that could lead to a specific place or specific shirt or carpet. Overall investigators prefer primary scenes because it’s

Behind every court case there’s a train of forensic science evidence and research. Forensic science is the application of scientific principles of criminal justice. In many court cases a forensic scientists is the one on the scene collecting finger prints, photos, blood samples and other evidence. Unfortunately one of the controversial issues in the forensic world is the evidence and its lack of verification of its reliability. In the field of forensics there are issues in finding proof in generating conclusion, fundamental knowledge to solve problems, and the whole false memory defense in the court. These issues can be solved in many ways like extensive research, preparation and training. These issues

They have to make sure that before they entered the crime scene, nothing in the scene should have been moved. While they are going through a walk-through, they may have to construct theories about what happened in the crime scene based on visual examination. Investigators have to take photographs of the scene and will later on be collected. Taking photographs of the scene will help them solve the crime because there are some points of the investigation that investigators may have overlooked evidence, and that evidence could be found in the photographs. After taking photographs of the scene, they will start to collect clue and evidence that may lead them to their possible suspect(s). What they may find in the crime scene are fingerprints which can be done using colored powder and a brush, other thizngs such as blood, firearms, hair, glass and many more things that can be found in the crime scenes.

Preserving evidence is one of the top priorities for investigators who are responsible for gathering and collecting evidence. Evidence can easily become contaminated or destroyed. Sometimes there may be individuals who don’t have a purpose of being on the crime scene, law enforcement official of course.

Crime reconstruction, as defined by Turvey, is the determination of the actions and events surrounding the commission of a crime. Often times, a reconstruction is based upon witness accounts, the confession of a suspect, the testimony of a living witness, or by the examination and interpretation of physical evidence (Turvey, 2012). When examining the evidence of the young 7-year-old female victim, petechial hemorrhages along the neck

The National Forensics Academy was full of multiple dimensions of crime scene investigation that I had not even thought about nor learned about in the past. The world of crime scene investigation is interesting to me because of all these aspects and because they are ever changing, and new and better methods are being discovered. Throughout the academy I learned about these aspects in detail and how there are various methods within each aspect. The aspects that I learned were how to photograph a crime scene, finger printing, foot impressions, crime scene sketches, blood spatter analysis, bullet holes, bones, and digging up a grace to recover a body. These aspects work together to investigate and recreate crime scenes.

There are many T.V. shows about crimes, and make the work look simple, but it is way harder in real life. The crime scene investigators have to involve a lot of different specialties to find the suspect and who the victim’s family is.There are people that examine the body, they are forensic anthropologist. They find the cause of death from only the bones of the victim. Federal agents from the FBI (Federal Bureau of Investigation) are some of the main investigators if there is a homicide but not if there is a suicide. Investigating a crime scene takes a lot of difficult and puzzling labor. It could take hours to find the killer and family or it could take days or months.

Introduction Crime scene reconstruction is the process of determining or eliminating the events and actions that occurred at the crime scene through analysis of the crime scene pattern, the location and position of the physical evidence, and the laboratory examination of the physical evidence.1 Reconstruction not only involves scientific scene analysis, interpretation of the scene pattern evidence and laboratory examination of physical evidence, but also involves mathematics which is playing such an increasingly important role in crime scene investigations. Mathematics can helping forensic scientists work out a range of problems including the trajectories of bullets, fingerprint recognition and the speed of moving vehicles, that an understanding

Forensic science borrows from a number of sciences which include: physics, Biology and chemistry. It therefore involves examination of a wide spectrum as compared to any other method of investigation. Due to the wide spectrum of investigation and evidence analysis the method offers; it ensures that the results are accurate and can be used in the court of law to make a decision. The method establishes the existence of a crime, the connection between the crimes and the

Criminalistics. According to discovercriminaljustice.com, “Criminalistics refers to the scientific analysis of evidence collected from the crime scene.” Criminalists look at all the evidence gathered in the crime lab, this includes, hairs, fibers, body fluids such as blood or spit (for the testing of the DNA), bullets, and others. Criminalists normally have a heavy science background, normally coming from something that’s chemistry or biology related. They also must be able to explain very complicated and scientific evidence (in a testimony) to the judge and jury.

Starting in the 20th century, law enforcers and courts in the U.S., as well as victims/bystanders, all have recommended the increased use of science in solving crime and achieving justice. In the 1960s, the Executive Crime Commission Task Force reports on Police, Science, and Technology called for making physical evidence more reliable in the investigation and judgment of crimes. Ever since the production of those statements, there have been outstanding advancements in the uprising of forensic facilities serving the criminal justice system and in the complications of scientific techniques employed to examine and interpret physical evidence. Forensic Scientists and investigators are now using both physical evidence and data collection as tools to solve crimes.

Today, more than ever, the quality of evidence in criminal cases is scrutinized because of contamination. Contamination is the introduction of something that physically corrupts a substance at a crime scene that was not previously there; it comes in many forms and most often times comes from the humans who investigate a crime scene. It is imperative that prevention of cross-contamination is implemented when gathering evidence. Several of the more sensitive forensic techniques such as trace analysis, bloodspatter interpretation, and DNA comparison are not being used to their fullest potential. Items of physical crime scene evidence are not always visible to the naked eye and may be easily overlooked so deliberate and methodical approach to collection and preservation of evidence is essential. Prosecutors have lost cases due to crime scene contamination; this could be prevented by simple and productive behaviors. The U.S. Supreme Court, in a leading case on physical evidence, stated:

The photographer that is present at the crime scene is responsible for making one picture worth a thousand words. Photography plays an integral role in the documentation of physical evidence found at crime and accident scenes as well as during forensic autopsies. Forensic Photographers are among the first crime scene technicians to arrive at crime and accident scenes. They walk through a scene to obtain an overview before they begin taking photographs. Forensic Photographers apply their technical skills and their knowledge of anatomy and forensic requirements to take photographs that convey the information that crime scene, criminal, medico legal, or forensic investigators need documented. These
