DNA Collection in the Forensic Science Community and its Effects on Solving Crimes
Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any Deoxyribonucleic acid (DNA) at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not too long ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a la...

...race, class and gender differences. In addition, to the inequality, methods of presenting DNA data is sometimes sloppy and has the scrutiny of being dismissed on the grounds of misleading or confusing evidence. Also, the errors in the forensic science community play a role in the high number of exoneration cases because of false identification.
Since DNA technology has been used there has been a high number of individuals convicted, linked or found innocent of a crimes. This technology has helped law enforcement catch suspects that may have never been found without the use of this technology. However, the research reflected that there is a need for clearer interpretations of the DNA results, better equality provided for all regardless of race or class and that errors should be reduced to prevent having cases that need to be exonerated.

- Forensic DNA Testing: Why Are There Still Bumps in the Road. Dr. Robbin W. Cotton, who is an associate professor and director of Biomedical Forensic Department at Boston University School of Medicine, gave a 60 minute talk about contemporary issues with forensic DNA testing. The main purpose of her talk was to make people aware of these issues and reflect about solutions for these problems. Her knowledge in the Forensic field comes from many years of experience in different crime labs. Dr. Cotton has worked over 200 cases among almost every state....

- Forensic Science: The Evolution of DNA Evidence Among the numerous new technological advancements that science has provided for the investigation of forensic evidence is the prevailing and contentious analysis of deoxyribonucleic acid (DNA), the organic material that makes up the genetic code of most organisms (plants, animals, humans). Through the process of DNA analysis, crime scene investigators are able to examine the DNA found in physical evidence such as blood, saliva, sweat, hair, skin, and semen....

- From cases such as OJ Simpson to Chandra Levy, DNA profiling also called DNA fingerprinting or DNA typing has played a major role in the criminal justice system. The law enforcement community uses DNA profiling to rule out or identify suspects. Unlike hair microscopy, bite mark comparisons, shoe print comparisons, and firearm tool mark analysis, DNA typing has been developed through massive scientific research and has undergone meticulous scientific evaluation (Innocence Project). DNA is a foolproof method of identifying a perpetrator of a crime.... [tags: Forensic Science]

- Forensic Science The idea of using the science has been started before the debuting of Sherlock Holmes in 1887, who had introduced about the forensic science to help criminal investigation. In history, the work of forensic scientists was performed by medical personnel. Until the end of eighteenth century, the attempts of French medical jurist Antoine Louis, crime solving Chinese book “ Hsi Duan Yu”(the washing way of wrongs), etc gave ideas about determining time of death, analyzing blood stain, identifying chemical used in crime, etc....

American Criminal Investigation Techniques And The Exponential Growth Of The Field Of Forensic Science
- The history of American criminal investigation techniques and the exponential growth in the field of forensic science can be traced back to our heritage in England. New innovations and specializations within law enforcement agencies along with an increase in crime created the need for the identification of suspects and the evidence of crimes they committed. Criminal investigation advancements and breakthrough scientific achievements in identification methods have coupled both fields into a mutually respected partnership....

- Before forensic evidence is presented in a trial, it must be deemed admissible (Imwinkelried, 1998). The admissibility of evidence is determined by its reliability, its relevance and its legitimacy. The evidence must be screened against the trial court’s Rules of Evidence. The trial court is the deciding factor on the admissibility or inadmissibility of any forensic evidence. The Rules of Evidence are utilized by the courts to determine if either side (Defense or Prosecution), have presented any evidence that may be irrelevant to the case at hand (Imwinkelried, 1998)....

- The Tremendous Potential of DNA Fingerprinting Abstract; This paper explors the effects DNA fingerprinting has had on the trial courts and legal institutions. Judge Joseph Harris states that it is the "single greatest advance in the search for truth since the advent of the cross examination (Gest, 1988)." And I tend to agree with Judge Joseph's assertion, but with the invention and implementation of DNA profiling and technology has come numerous problems. This paper will explore: how DNA evidence was introduced into the trial courts, the effects of DNA evidence on the jury system and the future of DNA evidence in the trial courts....
