Building the face of a criminal from DNA

The face of a killer constructed from DNA left at the scene of a crime: it sounds like science fiction. But revealing the face of a criminal based on their genes may be closer than we think. Today scientists are using genetic markers from DNA to build up a picture of an offender's face, a process known as molecular photo fitting.A DNA profile is only useful to detectives if a match can be found on a database.
