DNA testing has provided the biggest revolution in the identification of criminals since the adoption of fingerprinting in the early part of last century. Still, the technology has limitations. Most genetic tests take 24-72 hours but the time taken for DNA to go from crime scene to identification can span as long as 14 days. By the time that the results are back, the suspects often have been released. A newly developed test could make checking DNA from people arrested for crimes against DNA samples from crime scenes stored in forensics databases almost as easy as matching fingerprints.
