Finding justice can be hard at times when you can't really seem to find out who did it or why they have done it. Most likely the person will not confess to their crimes. In the passage "Forensic: Evidence, Clues, and Investigation" written by Andrea Campbell, it shows that forensic evidence is one of the most reliable evidences in the court of justice today. These evidences have been practiced for hundreds of years and it is still going strong as of today. The question is, what exactly is forensic science?…
Despite all of the good that using science in criminal investigation has done. Like all things there have been some hiccups. DNA testing has both enhanced and eroded the status of forensic science in criminal cases. Conventional forensic disciplines were unable to identify a perpetrator with any true discrimination. For instance, conventional serology (the study antigen or antibodies) field analysis of blood group substances was largely used in sexual assault cases during the 1980s (Mosby's Medical Dictionary 8th edition, 2009).…
The use of forensics in criminal investigations is to establish possible guilt or innocence of the potential suspect, linking crime between the suspect…
DNA Overturned Douglas Prade shot death of ex-wife in 1997. The evidence found on the defendant vehicle was blood on his lab coat; after 3 years examine the bite-mark by Margo Prade’s lab. Both side always have agreed there was struggle inside a Dr. Prade minivan and that the killer bit her, leaving an impression the upper –left arm through her lab coat and blouse. That was crucial crime scene evidence on the morning of slaying (Mayer,2015). The defendant was sentenced to live in the prison.…
INTRODUCTION Criminal evidence can be understood as any testimony or exhibit presented in context to a crime. There are different forms in which criminal evidence is presented as it is shows as prove to a crime. It is essential that facts should be accurate and legal and it can come from main parties like suspect, victim and also the parties those are related to the particular crime such as experts. In this regard, the government of UK developed the Police and Criminal Evidence Act 1984 which combat crime in England and Wales and provides codes of practices to exercise the power of police1. The act was formulated to build the balance between rights and freedom of the public and the powers of the police in England and Wales.…
The advancement of forensic science has progressed immensely since its conception. The contributions it has made for the legal system are immense. One such example are its techniques used to extract DNA during forensic cases. DNA is considered to be one of the most well regarded and highly assessed sources of information (Gershaw et al., 2010). Another important development used during investigations is CODIS or the Combined DNA Index System.…
In my opinion the validity of scientific techniques and the underlying reason behind an expert’s testimony, should be applied to facts of the case. Although the rules of evidence that involves the Daubert standard, could be a challenge to prove for forensic experts, the admissibility of evidence will actually be valid upon scientific techniques that have been experimented and tested with publications and peer reviews to back it up. The problem with Frye is that with the advances in technology and methodology in forensic applications the reliability of such evidence could be based off the mistrial and false rulings of many cases instead of techniques that were tested, peer reviewed, have known potential error rates, etc. Therefore emphasizes is being put on the importance of determining to reliability of scientific evidence by the origin of its scientific method. The scientific evidence will less likely be misused or falsified to sway one side or the other.…
Evidence Interpretation Over the years, there have been several cases that have been resolved with a false guilty plea or cases where a guilty party was not convicted of a crime. There are various elements that play a role in solving cases; evidence is a one of these key elements. Many factors can determine if the evidence submitted before a court of law is accurate such as how the evidence is collected, if proper protocell was followed before the laboratory’s handling of the evidence, and if the evidences was accurately processed by the crime scene laboratory by various forensic scientists. Furthermore, with the advances in technology in today’s society, various pieces of evidence such a DNA analysis have been considered a crucial element…
Hypothesis After analyzing the shoe wear patterns above, our team of forensic Pedorthists have gained valuable insight regarding the shoe-owner’s unique (abnormal) gait. Our leading theory describes gait mechanics that feature abnormalities including: severe overpronation and a low-gear toe off bilaterally. The shoes have clearly been used for for too long, possibly on hard, rough surfaces, as the forefoot and heel are starting to wear past the midsole, exposing deeper layers. Evidence 1) Crushed medial midsole (heel) & medial outsole wear (heel) – Ideally, the foot in late-swing is phase is supinated and slightly upturned (inverted) relative to the ground, this will result in lateral heel contact.…
The outcomes of a majority of crime scene investigations, which result in the prosecution of a suspect, is dependent upon the tenacity and admissibility of evidence. At trial, the evidence presented can be anything can be evidence that provides direct proof in support of a claim or belief of an assertion to prove or disprove any facts in speculation at trial or controversy, thus confronting flaws with proof or other means to form a conclusion or judgment. Simply put, anything that might have the slightest bearing on the outcome of a case can be broadly classified as evidence, provided it has a logical tendency to relate to the outcome of the case, therefore, in a criminal case, if the matter has a bearing on the guilt or innocence of the defendant,…
The use of DNA testing in resolving the inconsistencies in the post-conviction cases was particularly useful, as in these cases, the defendant was long requesting and claiming about his erroneous conviction. The technology was extremely useful for examining the biological evidence and proved extremely beneficial in capital cases by identifying the instances of wrongful convictions (Scheck et al., 2000). Then the study by Edward et al. , during the year 1996 study became the pioneer study that could establish the use of DNA testing in finding conclusive evidence for an innocent being wrongfully convicted.…
Lamond wrote this article in 2008 when the forensic science testimony was needed to prove the innocents. And Lamond wrote this article to educate forensic science lovers that the things that they see on the television is not real. The author of this article used special Lexis that only the forensic science students, and people interested in that field can understand the overall meaning that is being applied. The author used the DNA sample as an example to show the differences between the time periods it takes in reality to perform the test, and the time period it is shown in the television. In show the DNA analyzes takes 48 hours, but in reality it takes one to two or more weeks for the result to come.…
The quality and reliability of forensic testing is extremely important to the criminal justice system. If the best evidence is not submitted in court, the guilty may go unpunished or an innocent person may lose their liberty. One system to help address issues surrounding accuracy and quality of forensic testing is accreditation through the American Society of Crime Laboratory Directors and its Laboratory Accreditation Board (ASCLD/LAB). ASCLD/ LAB provides an independent, impartial and objective system by which laboratories undergo a total operational review.…
Forensic DNA is the process of using and collecting DNA from crime scenes to solve criminal investigations and to ensure accuracy and fairness in the Criminal Justice System. DNA profiling has grown significantly in the past years and has been extremely useful in identifying suspects, criminals and other people involved in the crime. If the suspect is unidentifiable, DNA evidence is compared to a DNA database to identify the criminal. DNA testing has both advantages and disadvantages many of which relate to ethical, emotional, economic and practicality issues. Research states that an increasing number of criminal investigations have used DNA testing to successfully identify the perpetrator.…
There are several ways to find the criminal of a crime. For example, there is testimony, direct, and forensic evidence. But, only one will give the truth of the crime. This type of evidence would give truthful evidence that none of the other evidences can give a person.…
