Photofitting

For over a year, Britain's Forensic Science Service (FSS) has employed what the agency terms "DNA photofitting," in which the genetic markers in the suspect's DNA found at a crime site are compared against a database of DNA markers.

The practice of rendering appearance from forensic samples is called “Forensic DNA Phenotyping” (FDP) or “molecular photofitting,” and there are a handful of scientists and companies around the world trying to make this not only scientifically possible, but also a useful law enforcement tool.
