Fingerprints are found everywhere millions of fingerprints can be on one simple object. This can be seen on the spatula or “murder weapon”.…
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.…

The cold case that I chose in which DNA played a crucial role was the Nicholas Yarris Case. The incident in this case took place in Pennsylvania in 1981(Innocence Project, 2016). The victim in this case was a woman that worked at a mall and was abducted after she got off from work (Innocence Project, 2016). She was then raped and murder; her body was left in a parking lot of a church (Innocence Project, 2016). Four days later Nicholas Yarris was stopped by the police for a traffic violation (Innocence Project, 2016).…
In the science text DNA analysis by Forensic Richard Platt. Look at the crime lab and DNA. Analysis look a DNA to fined fingerprint to know who DNA it is. Crime lab’s use DNA to look at crime’s to help and solve. Crime’s lab’s look at DNA that is left behind at the crime.…
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…
The period of c1886-c1926 saw great changes in investigative methods and thus lead to huge development in policing and how crime was dealt with. Such changes include the creation of the CID, and have shown to have more significance than others. For example, the introduction of forensic science enabled police to convict criminals in multiple cases, such as George Joseph Smith and Dr Crippen, rather than the use of telegram which only showed major significance in the Crippen case. A great flaw in 19th century policing regards the very few investigative methods available to detectives at the time.…
Evidence from thousands of unsolved rape cases and homicides have not been tested for DNA (Willing 1). This shows the problem because there are many cases that have not been tested for DNA when the evidence may be there. About 48,000 of 90,000 rapes in 2000 were not solved due to the lack of DNA evidence (Willing 2). This suggest that with better technology to analyze DNA these crimes could have been solved.…

There are several reasons that this occurs, and there are several ways to correct this life changing problem. This includes misidentification. This is a huge problem that leads to wrongful convictions. DNA evidence mishandling and tampering also help to convict innocent individuals. Lab technicians that are undereducated in handling, analyzing and interpreting DNA evidence is another major problem…
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.…
This is why science such as DNA should be strongly considered to help prove the guilt or innocence of the defendant; it’s essential. In order to fix this issue, there has to be improved police training, video recordings, and provision of expert witness testimony in order to have clearer evidence and confessions. Police reports can be also be sloppy if the officer does not get complete and accurate…
