New frontiers in forensic DNA analysis : Avancées de l'analyse génétique en criminalistique : dimensions internationales et conséquences pour le Canada

11 Mar 2009

The use of DNA identification was further expanded in 2000 with the establishment of the National DNA Data Bank, which allows investigators to rapidly screen DNA evidence against the DNA records of thousands of previously convicted criminals and evidence from other crimes. [...] Nonetheless, the information encoded in each region of DNA – defined by the molecular sequence of the DNA molecule – may differ between the two chromosomes in a pair. [...] The vast majority of the genetic information in the human genome, much of which is essential for life, is the same from one person to the next. [...] At the state level, California has recently adopted a policy requiring the state’s crime lab to report any partial matches discovered during a search of the state’s database, and to statistically analyze the probability of a relationship between the person who left the crime scene sample and the person profiled in the database.(33). [...] Nonetheless, since identical twins have the same DNA profiles, it is possible that a twin could be identified as a suspect based on a data bank match with the other twin’s profile.(37) Other features of the Canadian DNA data bank could deter the use of familial searching, despite the precedents in the United Kingdom and some American states.
