The inquiry identified a number of potential sources of contamination, including bench contamination, instrument contamination, failure to observe certain protocols, and deliberate contamination. However, the analysis of poor quality DNA samples may lead to uncertain results requiring substantial interpretation by the forensic scientist, and the potential for human error or varying opinions in the interpretation of the results. Ken joined LegalMatch in January 2002. [12], 44.14 Misconduct by a forensic scientist could also lead to a false result.

As in this case, those difficulties will include the poverty of the sample, its mixture with the bodily fluids of others, the age of the sample, the effect of the re-amplification process or the reliability of results and whether—because of or in spite of the encountering of these difficulties—any statistical probability can be pronounced as to the likelihood of other members of the community producing the same ‘match’. polymerase chain reaction (PCR) based testing is relatively insensitive to degradation. An independent inquiry could not find any conclusive explanation for the false positive results. But is this evidence alone reliable? We've helped more than 5 million clients find the right lawyer – for free. Using a method called DNA testing, also known as DNA profiling, scientists analyze a long chain of DNA to identify specific “loci.” These loci are very similar when you are comparing the loci of two closely related people, but among people unrelated, the differences are much greater. Quality assurance refers to monitoring, verifying and documenting laboratory performance. However, the analysis of poor quality DNA samples may lead to uncertain results requiring substantial interpretation by the forensic scientist, and the potential for human error or varying opinions in the interpretation of the results. 44.19 As a DNA profile contains only a very small section of a person’s DNA, it is possible that two persons might have the same DNA profile, by coincidence. Is there any need for further regulation? [10] See generally, D Kaye and G Sensabaugh Jr, ‘Reference Guide on DNA Evidence’ in Federal Judicial Center (ed), Reference Manual on Scientific Evidence (2000) Washington DC, 485, 520. A DNA sample may be contaminated with other human DNA in a number of ways, including: the crime scene sample may contain a mixture of fluids or tissues from different persons due to the nature of the crime; the crime scene sample may be contaminated during sample handling at the crime scene or in the laboratory; or, carry-over contamination may occur in PCR-based testing if the amplification products of one test are carried over into the mix for a subsequent PCR test. Bouzga recently gave a talk on the use of DNA as forensic evidence at a seminar in Oslo sponsored by the Norwegian Biotechnology Advisory Board. Close genetic relatives have more genes in common than unrelated persons. There is less likelihood of making errors when there is DNA evidence showing that someone is guilty or innocent. [11] While protocols and precautions can be introduced to minimise the opportunity for error dur-ing analysis or interpretation, the potential for human error cannot be fully eliminated. However, exact probabilities of a match remain disputed. A DNA sample may be contaminated with other human DNA in a number of ways, including: One reported example of sample contamination occurred in New Zealand when the DNA profile of an assault victim on the South Island was entered into the DNA data bank and matched the profiles obtained from two separate homicide scenes on the North Island.

It appears that DNA evidence is … 44.5 In R v Juric, the Victorian Court of Appeal highlighted the difference between evidence produced from a DNA sample that is: so pure and unadulterated that clear typings can be obtained at a large number of DNA sites, giving rise to statistical improbabilities running into the millions or even billions; and, so adulterated and so old, and the testing process of amplification so powerful, that the typings produced are affected by complications which preclude an expert from giving an opinion as to the statistical probabilities. Criminal Defense Lawyers, Present Furthermore, you wouldn’t be alone in thinking that. For example, where a DNA sample contains a mixture of several persons’ DNA, and the forensic scientist does not account for this, the resulting DNA profile may be incorrect.
