Forensic science technicians perform chemical, biological, and physical analysis on evidence taken from crime scenes. Forensic scientist experts help and aid criminal examinations by gathering and breaking down the evidence in order to confirm or deny any claims. Numerous of these experts spend a significant amount of time in either a crime scene examination or research center investigation. Most of these forensic professionals invest a great deal of time composing reports about their investigation. Investigate wrongdoing scenes to figure out what and how proof ought to be gathered. Take photos of the crime scene and evidence, they usually make representations of the crime scene, Record perceptions and discoveries, for example, the area and position of evidence, gather proof, including weapons, fingerprints.
When the body is already in the later stage of decomposition when it was discovered, the odds of medical examiner being able to tell the estimated time of death by his/her visual assessment is slim to none. The only way for a medical examiner to determine the time of death is to examine any trace of evidence found in the corpse. Example of evidence at such stage of corpse decomposition is the existence of insects living in the body. This is when the expertise of forensic entomologist come into play. Entomologists are scientists that studies all about insects. Entomologist expertise is very useful in aiding the medical examiner and homicide investigator to determine the victim’s time of death because they can identify the specific insect, the insect’s development as well as the season in which the victim’s death occurred (p.172). Another method that can aid the medical examiner and homicide investigators in finding out when the victim was killed is the help of forensics anthropologists. Forensics anthropologists are scientist who studies skeletons and human remains. The expertise of forensics anthropologist is very crucial when the body is discovered and already in the final stage of decomposition where the only way to find out the identity of the victim and the nature surrounding his or her death is by examining his or her skeleton or
Science has come a long way over the years. It has helped countless every day struggles and cure diseases most commonly found. What you don’t hear about however is the advancement of forensic science. Forensic science has helped solve countless cases of murder, rape, and sexual assault. In the case of John Joubert, it helped solve the murders of three young boys with one small piece of evidence that linked him directly to the crime.
A positive aspect of this is that forensic scientists only need a small amount of a sample to get the results they need (“Forensic Science” 12). These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12). Forensic Science Technicians stated that “crime scene investigators may use tweezers, black lights, and specialized kits to identify and collect evidence.” They also stated that examining autopsies prove to be beneficial in a crime investigation (“Forensic Science Technicians”
Forensic scientists are used in many fields of study, such as criminology, pathology and biology. For example, if a person was to all out of a sudden die randomly, the forensic scientist that has a specialty in criminology, pathology and biology would be called to deal with this situation. The scientists have to examine the body to determine if the cause of the death was natural or not. After that they would either examine the body for fingerprints or wounds, or check if the person had any health problems in the past. The forensic scientists would apply the principle of blood spatter analysis. Blood spatter analysis is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed. By using the analysis they observe the spatter of the blood, the investigators and forensic scientists can determine how the victim was wounded, what weapons were used and where the object hit the body. Evidence is really important because it can be either stopping the criminal or letting him
William Maples is a forensic anthropologist, someone who specializes in the human skeletal system, its variations across the world, and its changes through life and across many lifetimes; not a forensic pathologist, a medical doctor with its residency training in pathology. Maples defends the use of science to understand human nature; he defends the science of forensic anthropology for its usefulness in solving gruesome crimes and historical mysteries. He says that it can pay for itself in reduced court costs and that every state in the United States should have at least one on staff.
Forensic Science Technicians collect, identify, classify, and analyze physical information related to criminal investigations. They perform tests on weapons or substances, such as fiber, hair, and tissue to determine significance to investigation. They can testify as expert witnesses on evidence or crime laboratory techniques. They may also serve as specialists in area of expertise, such as ballistics, fingerprinting, handwriting, or biochemistry. Forensic Technicians are responsible for many tasks, these include:
Forensic scientists and investigators can employ numerous forensic techniques to help solve this crime. These can include using biological examination in terms of detecting and identifying bloodstain pattern analysis, analyse ballistics and fingerprints.
One of the central frameworks involved in dental identification is comparing post-mortem remains with antemortem dental records, by which further analysis can provide a confirmed identity (Pretty 2001, p. 360). There are a wide range of conclusions that can be reached when reporting dental identifications. The American Board of Forensic Ondontology recommends the following four guidelines for conclusions, including: positive identification, possible identification, insufficient evidence and exclusion (Pretty 2001, p. 362). Since there is no minimum number of concordant points which are required to make a positive identification, discretion of identification lies within the expertise of the ondontologists (Pretty 2001, p.
that allowed for “one police offer who shall be a woman”. She was to handle juvenile and female cases and to investigate what led them to take part in crimes (Horne, Peter).
The remaining’s that were found such as the skull, pelvis, femur, and humorous helped determine sex, age, race and height. After analyzing the bones, the team came up with a female black/asain. Falling in between the height of 4”5’ and 5”1”.
I have recently inquired information about a specific investigation that went on a few months back. The investigation had informed the intelligent investigators that there had been a death at a particular house. Now this death was very unusual, because the man that had been found dead was under a truck crushed by the vehicle engine. The unusual thing about it was that the man had worked with this specific type of vehicle for quite a long time. When the investigators got to the home of the man they found him underneath the truck and the garage was on fire. When all were taken care of the officers arrived, they lifted the truck off of the burned remains of the man, they proceeded to take pictures of the cinerary and make sure that everything that was
First of all, it is well known that there is a lot of money will be spent on DVI by analysing DNA, but the participation of Forensics decreased the cost of money and save more time in DVI observably, because they use some “simple” ways to achieve the “expensive” goal which is analysing skeleton. According to Mundorff opinion (2012), "Historically, anthropological involvement in DVI operations has been limited to developing biological profiles from skeletal remains to aid in identification." (pg.131-139) For example, rebuilding faces by using sculpture is a very effective way because it cost a little money and the Forensics team will receive an result which is beyond Imagination. Therefore, Forensics anthropologist are becoming more and more important for Forensics team. Also, bodies are an important part of DVI for Forensics team. However, the anthropologist have the major knowledge in this subject field, so, the Forensics anthropologist are suitable for this job exactly as Mundorff says (2012), "Most forensic anthropologists, like forensic archaeologists, have extensive field experience in searching for, mapping, and recovering human remains. These skills make forensic anthropologists valuable in the initial assessment of any disaster scene." (pg.131-139) Therefore, the knowledge and the working experience is important for the Forensics team, and it promote the value of Forensics anthropologist in the Forensics team.
DNA is the carrier of genetic information in humans and other living organisms. It has become a very useful tool in forensic science since it was discovered. In forensic science, DNA testing is used to compare the genetic structure of two individuals to establish whether there is a genetic relationship between them.
A significant part of this field is anthropology– the study of the human body and its decomposition process. human bodies and their decomposition play an important part in the forensic investigation. But even more important in many cases is an analysis of the bones. Often the body or bodies is/are in an advanced state of decomposition,
