DNA testing is not only a predominant forensic technique for identifying criminals, but it has also become a method of postconviction exoneration of the innocent.  DNA testing makes it possible to obtain conclusive results in cases in which previous testing had been inconclusive.  Postconviction testing has been requested not only in cases in which DNA testing was never done, but also in cases in which the more refined technology may result in an indisputable evidence.

Handling Postconviction Requests

The way DNA evidence is collected, preserved, and tested is critical to the success of its use in criminal cases. NIJ's Postconviction DNA Testing: Recommendations for Handling Requests examines legal and biological issues applied to DNA technology in the appeals process while recognizing the value of finality in the criminal justice system. The report suggests recommendations for prosecutors, defense counsels, courts, victims' advocates, and laboratory personnel when receiving requests for postconviction DNA testing to maximize the future benefits and use of DNA in postconviction proceedings.
