Scientists Create Mugshots From Perps’ DNA

Elvis_mugshotThis is some next level CSI! New Scientist reports on the DNA-generated mugshots:

A murder has been committed, and all the cops have to go on is a trace of DNA left at the scene. It doesn’t match any profile in databases of known criminals, and the trail goes cold. But what if the police could issue a wanted poster based on a realistic “photofit” likeness built from that DNA?

Not if, but when, claim researchers who have developed a method for determining how our genes influence facial shape. One day, the technique may even allow us to gaze into the faces of extinct human-like species that interbred with our own ancestors.

It’s already possible to make some inferences about the appearance of crime suspects from their DNA alone, including their racial ancestry and some shades of hair colour. And in 2012, a team led by Manfred Kayser of Erasmus University Medical Center in Rotterdam, the Netherlands, identified five genetic variants with detectable effects on facial shape. It was a start, but still a long way from reliable genetic photofits.

To take the idea a step further, a team led by population geneticist Mark Shriver of Pennsylvania State University and imaging specialist Peter Claes of the Catholic University of Leuven (KUL) in Belgium used a stereoscopic camera to capture 3D images of almost 600 volunteers from populations with mixed European and West African ancestry. Because people from Europe and Africa tend to have differently shaped faces, studying people with mixed ancestry increased the chances of finding genetic variants affecting facial structure…

    personally
    I prefer it when they reconstruct mug shots
    from the residue of auras captured from the aether

    This opens up a whole new black market for barber shop floor sweepings and pedicurists dirty foot water… Just sprinkle a little of each at the scene of your crime and walk away laughing.
