Part 1
When it comes to identical twins we have come to learn that twin identical or not will not have the same fingerprint. Fingerprints are unique and are made to identify a person. So even when you clone humans or other primates I believe that the Friction ridge pattern will be similar but not exactly the same. I believe that in the process of the cloning process something will cause the fingerprints to come out different. Because cloning is dangerous there has yet to be a human cloning, but there have been cloning of monkeys and according to the data even though the monkey was cloned the fingerprint still isn’t the same.
Part 2
Next we will discuss the processes used when dealing with latent prints. First I will discuss the analysis of a latent print. So first when a latent print is sent to the lab who conducts the analysis? The forensic analysis is he person that conducts the analysis, or a fingerprint technician or even a police officer. Bu...
Other evidence located within the grave consisted of a generic watch, two cigarette butts, a button, a washer and a shell casing. All of these could be analysed for finger prints and DNA. The cigarette butts would also show a serial number indicating the brand (shown in Figure 3), which can be useful if it is found a victim or offender smokes a particular type of cigarette.
...me scene, by recreating the scene using the blood direction a bloodstain patterns. Bloodstain pattern analysis use biology, chemistry, math, and physics to solve a crime. In doing research on this topic there is a lot of detail to go into this topic, so in suggestion this paper need to explain the other different investigators that process any crime scene.
CBS’s CSI: Crime Scene Investigation exploded into popularity when it aired in 2000, opening doors for the creation of other similar criminal investigative television shows involving forensic evidence such as Cold Case, Criminal Minds, and Bones. Many of these CSI-type shows present a murder or crime solved within an hour-long episode using forensic evidence conceived by glamorized CSI personnel and sometimes fabricated methodologies and technologies that only exist on television. Despite just being shows, one wonders whether these popular shows have skewered public perceptions about forensic evidence in real court cases and have impacted the outcome of court verdicts. The CSI Effect, explained by Kim, et all, was named after the television show
Preview of main points: Now I am going to take you through the process of identifying, collecting and analyzing fingerprints.
Bones is an American crime drama television series that originally ran on the Fox network on September 13, 2005. This show, Bones, is a forensic anthropology. Forensic archaeology utilizes science, as well as state-of-the-art gadgets to solve mysterious homicides. It starts by finding human remains dumped somewhere, then casually presenting some hints or signs that would not mean anything from the first look. However, these clues are thoroughly investigated and examined, and become pieces of evidence that shed the light, that leads to the criminal. This episode shows how women can lead their co-workers in the workforce as well as have a family. And the ability for women to handle computers and new technologies just as good as men do. “The Scare
Evidence analysis and ranging is the most crucial stage of investigation. The success of the case exposure lies in the gradual evidence research and collecting prior to the laboratory analysis. The CSI systematically makes his way through the crime scene collects all potential evidence, tagging, logging and packaging so it remains intact on its way to the lab. Depending on the task breakdown of the CSI unit he may or may not analyze the evidence in the lab.
The crime scene was then examined and a list of possible pieces of evidence were recorded down. Including a sketch of the crime scene, Anna Garcia’s house, with the locations of all of the pieces of evidence. All of these items listed help develop a theory about Anna’s death. This theory then helped establish a list of possible suspects. The person of interest list included a number of four individuals and each one had a relation with Anna. The list included (1) Alex Garcia- Anna’s ex-husband. They had an unpleasant divorce the year before and in a result Alex quickly remarried a much younger woman, while Anna remained single. Alex and his newlywed wife are expecting to have a baby soon. Although, Alex may be suffering from a few financial
The easiest way to figure out who was at the crime scene is by taking fingerprints. Good impressions such as fingerprints can be the most valuable pieces of evidence in a forensic investigation. Impressions help link a person to a crime scene or crime as well can provide information on any weapon that could've been used at the scene. An educated technician would compare and search fingerprints manually and on AFIS computer system for classification, comparison and identification. "Analyzing evidence is not a quick or simple process.
The origins of DNA were first discovered during 1857 by Gregor Mendel the "Father of Genetics”, whom was performing an experiment of genetics with pea plants, and would provide a basic foundation towards DNA and Genetics. Friedrich Miescher and Richard Altmann in 1869 were also part of the first people to discover DNA. While testing some sperm of a salmon, they discover a strange substance that they would name as "nuclein", which is known as DNA. This new form of "nuclein" (DNA) would be found to only exist in chromosomes. Frederick Griffith, a researcher, found the basis on DNA, from a molecule inheritance experiment involving mice and two types of pneumonia. His findings were that, when virulent disease is heated up (to kill) and is injected into a mouse, the mouse survives. Unlike the second mouse that has been injected with non-virulent disease and virulent disease (that had been heated and killed) is killed. This would be caused by an inheritance of molecule (transformation) of virulent bacteria passing on a characteristic to the non-virulent. DNA findings would continue to be tested and tried to better understand how DNA works.
DNA analysis is a scientific process among the newest and most sophisicated of techniques used to test for genetic disorders, which involves direct examination of the DNA molecule itself (Lyman, 2014) . Today crime labs use mtDNA analysis. This type of analysis allows smaller degraded pieces of DNA to still be successfully tested (Lyman, 2014) . There are several steps taken when analyzing DNA in forensics. When testing scientists must first isolate the DNA so it is not contaminated and can't be used. Lab technicians the take small pieces of the DNA, conserving as much as they can encase they need to test again. Once testing is done the next step is determining the DNA test results and finally there is the comparison and interpretation of the test results from the unknown and known samples to determ...
The criminal justice system has changed a lot since the good old days of the Wild West when pretty much anything was legal. Criminals were dealt with in any fashion the law enforcement saw fit. The science of catching criminals has evolved since these days. We are better at catching criminals than ever and we owe this advancement to forensic science. The development of forensic science has given us the important techniques of fingerprinting and DNA analysis. We can use these techniques to catch criminals, prove people's innocence, and keep track of inmates after they have been paroled. There are many different ways of solving crimes using forensic evidence. One of these ways is using blood spatter analysis; this is where the distribution and pattern of bloodstains is studied to find the nature of the event that caused the blood spatter. Many things go into the determination of the cause including: the effects of various types of physical forces on blood, the interaction between blood and the surfaces on which it falls, the location of the person shedding the blood, the location and actions of the assailant, and the movement of them both during the incident. Another common type of forensic evidence is trace evidence. This is commonly recovered from any number of items at a crime scene. These items can include carpet fibers, clothing fibers, or hair found in or around the crime scene. Hairs recovered from crime scenes can be used as an important source of DNA. Examination of material recovered from a victim's or suspect's clothing can allow association to be made between the victim and other people, places, or things involved in the investigation. DNA analysis is the most important part of forensic science. DNA evidence can come in many forms at the crime scene. Some of these forms include hair; bodily fluids recovered at the crime scene or on the victim's body, skin under the victim's fingernails, blood, and many others. This DNA can be the basis of someone's guilt or innocence; it has decided many cases in the twentieth century. As the times continue to change and the criminals get smarter we will always need to find new ways to catch them. Forensic science is the most advanced method yet, but is only the beginning. As the field of science grows so will the abilities of the
“Anthropology is the science which tells us that people are the same the whole world over - except when they are different.” Nancy Banks Smith, british television critic. Anthropology is the study of what makes us human and how/why we interact the way we do. Anthropologists take a broad approach to understanding the many different aspects of the human body (site). More specifically, forensic anthropology is the examination of human remains for law enforcement agencies to determine the identity and cause of death in unidentified bones. Although being a real forensic anthropologist is not quite like being Temperance Brennan from Bones, there are many needs and uses for forensic anthropologists in not just the police force, but even in military
Crime investigators have the job to solve crime and find the suspect responsible. Sometimes the offense is very difficult to solve, but with the right pieces of evidence and tools, the investigation can be answered a little more easily. The use of fingerprints is a main tool used at crime scenes. Investigators find these at the actual crime scene and analyze them at the lab to determine whom the prints belong to. Each person has an individual print which is why this is a very useful piece of evidence. Sir Francis Galton found that the prints could be categorized into different types as well as different groups. The research of fingerprints from decades before has shaped the way detectives identify suspects and victims.
Crime Scene Investigation For my assignment, I will be looking into the case of James Bulger, aged 2 years old, who was kidnapped and murdered by John Venables and Robert Thompson on February 12th 1993. Through evidence found at the crime scene and testimonial statements, the police saw that the two boys, ages 11, abducted James from Bootle Strand Shopping Center, Liverpool. They took him on a long, aimless walk where they brutally attacked him and left him for dead. In my assignment I will show how work done by the police, forensic scientists and Investigators helped to convict Jon and Robert.
There are several steps that need to be taken in order to process a crime scene. Some of the steps include: securing the scene, a detailed search, documenting the crime scene, collecting and preserving evidence, and finally releasing the scene. All of the following steps are crucial to avoid any possible contamination or otherwise compromise the scene before it can be released. Few, if any additional opportunities exist when processing a crime scene, so the first time is most pertinent.
