Abstract:

The use of DNA testing as part of police investigative work has increased substantially since its emergence in the 1980s. The objective of this review has been to synthesize the existing evidence on the effectiveness of DNA testing as part of routine police investigative practices compared to other more traditional forms of investigation. We have identified five studies that clearly addressed the effectiveness of DNA testing as part of a criminal investigation to improve criminal justice system outcomes. The evidence suggests that DNA testing has positive value when used to investigate a broad range of crime types. There are caveats. Other than a methodologically sound evaluation in five U.S. jurisdictions, the evidence of the utility of DNA testing for serious violent crimes is based on studies with clear methodological weaknesses.
