Three months later, the same crime had been committed along with the attempt of murder of her husband. Before the house engulfed in flames, firefighters and rescue teams were able to drag the bodies out.

With new technological advancements, it should be thought that this form of evidence is the only reliable source for providing just outcomes in court cases. It is a technique that leads to a criminal’s conviction or acquittal. The many skills and areas of DNA help the reliability of an investigation as each expert area are assigned professionally. Whilst DNA testing can be incorrectly interpreted and used ineffectively leading to false imprisonment, it enhances criminal justice for the whole community.
DNA (Deoxyribonucleic Acid) evidence is stated as the most dependable source for forensic scientists to rely on, providing the evidence beyond reasonable doubt in court cases. When DNA had been first introduced into courts, it had received high levels of scrutiny. However, DNA testing have survived court challenges and have shown to be the most convincing scientific evidence still existing. Although, it is argued among many that 99.9% of human DNA is exactly the same, there is enough to single out criminals with this technique. While this source of evidence was checked for reliability, FBI has estimated

    The number of matching alleles detected in DNA samples like blood found at the crime scene proves the probable association between the suspect’s sample and the crime-scene sample (Turman, 2001). Because DNA evidence was fairly new, the magistrate judge then conducted a six-week hearing using the Frye rule and the introduction of two hundred exhibits relating to the FBI’s methods. The issue at trial was to determine if the proposed DNA evidence violated the defendants 6th amendment rights and if it is generally accepted in the scientific community. During the trial hearing the government employed six expert witnesses and called Dr.Eric Lander as the courts witness. The government provided expert witness Dr. Caskey, a forensic DNA scientist, who operates the FBI procedures for DNA identification in a major genetics laboratory.…

    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).…

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…

    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.…
