Each person has their own unique DNA that makes them different from others. The scientists had invented the DNA analysis procedures which helps to bring down the criminals due to the DNA that they left behind the scene. These techniques are collecting the DNA specimen and extracting DNA from the specimen. In addition, other areas such as immunohistochemistry (IHC) and forensic chemistry also help the investigators to complete their jobs. DNA analysis is also used to prove the relationship…
With the onset of television shows like CSI and NCIS, people have their own views of how the Criminal Justice System uses and obtains forensic evidence. One of the main issues with the media influence today is how people assume that forensics in the real world is exactly like the shows that portray it. “If people’s reactions to crime and criminals are generally shaped by the mass media, then it seems reasonable to assume that public reactions to criminal cases are shaped by shows like CSI”…
Forensic science dates back to 44BC with the first recorded autopsy being of Julius Caesar. Forensic science is “any science used for the purposes of the law, and therefore provides impartial scientific evidence for use in the courts of law, e.g. in a criminal investigation and trial.” Forensic science uses the evidence collected at the scene of a crime to help in the conviction of the criminal who committed the crime. There have been many technological advances in forensic science as time has…
DNA testing which can also be label as DNA fingerprinting, DNA profiling and even DNA typing is considered a forensic technique that can be used to identify a person by their characteristics of their DNA. (What is DNA Testing?, 2016). DNA testing was developed in 1985, to identify a suspect and placed that initial suspect at the incident location during the time of the crime. DNA testing have evolve in the past decade that is can be used to study the animal populations. DNA testing can collected…
The National Institute of Justice (NIJ) recently declared that “all biological evidence (any physical evidence that can connect an offender to a crime) found at crime scenes can be subjected to DNA testing” (NIJ, 2012). Forensically speaking, biological evidence represents the collection and preservation of materials that contain DNA (deoxyribonucleic acid), a cellular fingerprint that is unique to everyone (University of Leicester, 2016). Within the past 30 years, DNA testing gained notoriety…
Law reform is the process by which the law is modified and shaped over time to better reflect the social values that society feels are important. Whilst the legal system deals effectively with many technological issues and enforcing rights, there are several areas that require improvement. The rapid change of technology in the 21st century makes it difficult for the law to keep up with the changes to these technological developments, thus creating the need for law reform. The increasing rate of…
In trying to identify the victim who was murdered, there are methods that are used to identify a victim, for example, if only the teeth and bones were left it are important to find out who the person was by using the methods of anthropology, ontology and DNA (Fisher, 2012 p.128) Anthropology is a way for scientist that work in forensics. It is a way to see what happened to a body including injuries or disease. In addition, will determine the sex and age of the deceased person by using various…
Contrary to people believe, DNA evidence are available in fewer than 10 percent of violent crimes. These cases are typically rape and murder cases, where it is more likely the offender will leave skin tissue or bodily fluids that will yield DNA. More than 90 percent of the persons exonerated by DNA evidence were convicted of rape, murder, or both. DNA evidence is often available in these crimes of violence unless the perpetrator takes measures to remove all hair, semen, blood, and other bodily…
Forensic evidence has been around for centuries. Whether it is using things like fingerprints or soil samples, it has been a significant form of support to find and convict criminals. Only recently, though, has DNA analysis become a major part of the forensic evidence process. The goal of this paper is to discuss how DNA analysis can be applied to dental, hair, and blood evidence to solve crimes; also, the importance of an accurate and detailed chain of custody log will be shown. The standard…
DNA evidence has become more advanced and accurate means of identification. Everyone has his or her own unique DNA and no two sets are alike. With modern advances small samples many years old can now be identified breathing new life in cold cases and in some cases set innocent men and women free by clearing their name (Dempsey & Forst, 2011). This has created a backlog of cases both old and new. With a limited number of qualified labs it has led to mix up between cases. DNA has been a…
