Though there are DNA techniques such as Familial and Phenotypical analyses that can narrow the search for a suspect, in the end, DNA is most useful if it can be profiled and matched against another sample. Databases play a large role in such comparisons when an unknown crime scene sample is obtained. Even if no suspect is on the radar, a “hit” on a database comparison can lead investigators down the right path. But these take time. And if a killer is “out there,” time is often critical. What if investigators could obtain a sample at the scene and compare it against 20 million databases sample in only a few seconds? That would be amazing. But guess what? With the FastID algorithm, it seems to be possible.
Could be a game changer for law enforcement.
