One of the most necessary aspects of criminal justice is forensic science, which involves the study of scientifically inspecting physical evidence, which has been collected from a crime scene. Some people define forensic science as being the application of science to law enforcement. You can use forensic science in the most challenging situations, for example, if there are no witnesses to a crime, or any leads, it can usually mean that forensic evidence is all the court has to work with. For example, if a body has been left in a septic tank in the middle of an abandoned warehouse, and the body is beyond recognition by physical features alone, forensic teams will be called in to examine dental work and observe the skeleton, in order to determine …show more content…
Collecting evidence of murder, suicide or domestic scenes. Most often this uses maggots and eggs in order to gather information on which order these insects appear in, and where were they found on the remains. This is extremely helpful because the insects are very specific; they only appear in one certain place during one certain period of the year, which means if the order they appear in changes, this will give major evidence to the investigation. Ultimately this field section focuses on the criminal segment of the law system, and concentrations on the feeding of insects on human remains. Forensic entomology is a hugely varied field; you can use it to gain evidence in many ways. Insects play a vital role in death, and even causing death. It has been shown that many insects are within the top 20 origins of automobile casualties. Insects have even been known to cause airplane crashes due to flying in and obstructing the engines. This means forensic entomologists can use the remains of the insects to provide evidence towards what caused the crime. Another use for insects is during the explanation of the blood splatter analysis. Many insects will corrupt blood splatters due to walking through the blood. However, scientist from other branches of forensics, they will not understand why there are abnormalities in the blood pattern, they will be unable to pick out any insect tracts through the blood. This could drag blood onto the ceiling; even flies will eat the blood and pass this through their feces onto another area of the crime scene. If the venue were already very severely infested there would already be drops of feces around the crime scene which would confuse the analysts as they would already test positive for human blood prior to the crime occurring. This is the main reason why it is important to understand Forensic Entomology, to understand the different scenarios that may
First off, the main and most commonly known use of forensic anthropology is to catch criminals and protect the living. It can be referred to as giving a voice to those who cannot speak- the dead. As stated in the documentary Secrets of the Body Farm, forensic anthropology was originally
In a forensic science lab, the criminologist must have access to a variety of chemicals, and compounds; as well as different specialized machinery.
Forensic Science is the career field I am interested in. I would enjoy being a forensic science technician because of my interest in mysteries and figuring things out. This career choice is the right choice for me because I would only need a Bachelor’s degree, it would be work I enjoy doing, and I would make an exceptional salary. Forensic science technicians aid investigations by collecting and testing evidence. Many technicians spend time either in a laboratory or on the field in crime scene investigation.
Carefully and thoroughly analyzing the significance of the position and shape of blood patterns along with their origin and trajectory is very important in an investigation. The process is sufficiently complex and should only be done by an examiner who is experienced in such determinations. The interpretation of bloodstain patterns is the most important of all and requires carefully planned control experiments that use surface materials comparable to those found at a crime
• Collect evidence from crime scenes. • Testify in court about investigative or analytical findings. • Use photographic or video equipment to document evidence or crime scenes. • Visit morgues, examine scenes of crimes, or contact other sources to obtain evidence or information to be used in investigations. • Reconstruct
Forensic science has been an aid to the law enforcement community for years now. It has solved cases that were unsolved years before DNA and science started to play a role with cases and law enforcement. The case of Samuel Reeves and James Layne was unsolved in the year 1989, this was considered a cold case because it had been years since they found who the murderer was. This case was considered a crime of passion, where it first started off by kissing and having the same attraction towards each other, but when James Layne started to get aggressive and not respecting Reeves decision to not have sex, that was when things got hectic. Forensic science helped this case by the use of fingerprints, they found the fingerprints in a bottle, and when
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.
career journal activity: 1.2.3 Bone Detectives description: read interviews with forensic anthropologist and synthesize a definition of the career. my work: A forensic anthropologist is a group of people who investigate a dead body to discover its gender, ancestry, stature, ethnicity and other unique features about it. Through their investigations they can also discover how the victim may have died and other important background information that can move the investigation further in solving the case. A forensic anthropologist needs to be able to conduct research, know their bones, muscles and other body parts along with be able to make educated conclusions related to the received data and observations they find and make. activity: forensic anthropologist
The Department of Justice says, "States began passing laws requiring offenders convicted of certain offenses to provide DNA samples. " That DNA evidence can help convict someone of a crime and it helps to uncover more things about the crime itself. Investigators have been using forensic science to help them solve cases since before the 90 's, mostly fingerprints that were found at the crime scenes and on the victims (O 'Brien). DNA evidence has solved countless cases including ones that happened over a prolonged period of time because of the technological advancements there is
Forensic Science was still in its infancy when first introduced alongside other applications
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”
Getting a job in forensics takes the ability to incorporate all of the scientific strengths learned and the love for solving crimes. Giving expertise on legal activities also plays a major role in investigating and solving misdemeanors(“Discover Careers in Forensic Science”). Many occupations in forensics can be sometimes labeled as morbid or gruesome. Some of these careers may include, forensic crime scene investigators, coroners, anthropologists, and pathologists(forensic medical examiners)(Palmer). These professions salaries can range anywhere from 50,000 to over 200,000 a year(Kaelin).
DNA in Forensic Science 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. One example of the use of DNA in forensic science that is important in biology today is comparing a suspect’s DNA profile to DNA that was discovered at a crime scene.
The physical evidences are gathered at any crime scene, for example, hair, fibre, blood, fingerprints, footwear, bare-footprints, tire impressions and any fracture
Crime scene photography, sometimes referred to as forensic photography or forensic imaging, is the art of producing an accurate representation of an accident or crime scene. Crime scene photography is an important asset in the collection of evidence at the crime scene, documents the appearance and location of victims, shell casings, footprints, bloodstain patterns, and other physical evidence. In order for photographs to be admissible in a court of law, the standard for photographs of crime scenes and evidence must be of sufficient quality. Photography has a vital role in the decision made in court because the pictures are to represent the scene as it was exactly. Digital SLR single reflex camera is the most often used camera in crime scene investigations.
