Building the Face of a Criminal From DNA 59

Dave Knott writes: It sounds like science fiction, but revealing the face of a criminal based on their genes may be closer than we think. In a process known as molecular photo fitting, scientists are experimenting with using genetic markers from DNA to build up a picture of an offender's face. Dr. Peter Claes, a medical imaging specialist at the University of Leuven, has amassed a database of faces and corresponding DNA. Armed with this information, he is able to model how a face is constructed based on just 20 genes (this number will soon be expanded to 200). At the moment, police couldn't publish a molecular photo-fit like this and hope to catch a killer. But that's not how Dr. Claes sees the technique being used in a criminal investigation. "If I were to bring this result to an investigator, I wouldn't necessarily give him the image to broadcast. I would talk to him and say okay, you're looking for a woman, with a very specific chin and eyebrow structure."

    If you're a bad person we'll reconstruct an identical clone of you and imprison it as your punishment.

    • If you're a bad person we'll reconstruct an identical clone of you and imprison it as your punishment.

      And any clones of me would not have my memories as those aren't genetic, so why are you going to torcher an inoccent person?

      Also not at all on topic.

    • More like: If you commit a crime, we'll imprison you and let your clone take over your life. If your clone commits crime, a clone of your clone will take over your life while your clone is imprisoned. And so on.

      Cue criminal being released from prison after his sentence is finished and finding that everyone likes Clone better than Original. Original kills Clone, is convicted of murder, put in prison, and Clone 2 is created to take over Original's life. (Someone needs to write this sci-fi story now!)

  • How long before a full DNA emulator? Something that would render a fully formed human being starting from his\her full DNA code?
    • Don't forget that environmental factors would render a full human rendering completely inaccurate. Do you go to the gym? Do you have long hair? Do you tan? It can be close, but not perfect.

        rendering completely inaccurate... can be close, but not perfect... *sigh*

      • It doesn't have to be perfect. The more people they have, the more perfect match they will get. They can also mix techniques: take fingerprints with, say, 80% acccuracy and then pick their faces based on those renderings. But the real power here is that those who think are not guilty will have their 1:1 DNA matching taken. The face matching is just a tool for investigating those who don't want to have their DNA matched.

      I'm not a biologist, but I'm going to go with "never". From what I understand, we can predict a persons height with far greater accuracy by simply measuring the height of their parents than we can with DNA. I have serious doubts about our ability to predict, accurately, anything more complicated.

      We've got at least one regular biologist around here. I'd like to hear their opinion.

      • If nutrition varied, there's no way you could determine a child's height from measuring their parents. You couldn't do it from DNA for the same reason.
        Very short people who grew up poor can have children that tower over them by their 12th birthday if the kids grow up in a better environment.

          That makes you wonder how much about a person's appearance is genetically determined -- and if the science fiction in the summary is possible at all.

    I like how he talks about how he would envision seeing this used, but, I think he actually has it backwards. Not surprizing since, his expertise is in the technique, not necessarily in what it may be used for.

    Rather than "you are looking for...." better is to hold this back and narrow down the field. "You have X suspects, now you can eliminate all that don't match this". That will give you better results than "look for people who match this".

    This sort of thing has come up many times with the use of this sort of statistic. There are only a handful of blood types, for example, but, if you can say with certainty that the suspect is one of a small group of 2 or 3 people, then blood type might get you down to 1....even though it would be otherwise pretty useless without other information to go on.

    • If you have their DNA, why bother with modeling their appearance? Just do DNA tests on the small group of suspects.

      • You are assuming that they have suspects. There are lots of cases where all they have is just the sample of DNA and no suspects at all. If someone is assaulted and manages to scratch the other person there is DNA evidence but not necessarily a known suspect. Same goes for sexual assault though a different type of DNA. And it seems like they can get DNA off of lots of different things now (pizza?) so they can collect it in cases where they don't have suspects. Plus there's DNA evidence from plenty of co

      • by TheCarp ( 96830 )

        Who says you have all their DNA? Just because you have suspects doesn't mean you have enough evidence to mandate they cooperate. You also might be too moral (yes, I consider it quite wrong) to go about using loopholes to surreptitiously collect their DNA, or just lack the resources to pull it off.

        Or perhaps, this will rule out many (or all) of your suspects before you subject them to sampling, possibly against their will.

        Or more likely this will be used to generate grant money and will never be used in any

  • Everywhere you go in public will be trackable and connectable to your online "public" activities by mapping your DNA to a picture of you online. Laws will not be able to prevent this. This will just become the new norm. . .

    Of course, this will also increase the public scrutiny of public officials and other powerful individuals, which I can only see as a good thing (as any "House of Cards" fan should be able to agree with. . .).

    "Researchers have moved one step closer to facial reconstruction with DNA by discovering the genes that help control the width of the human face. A recent study of almost 10,000 individuals revealed five genes associated with different facial shapes – known as PRDM16, PAX3, TP63, C5orf50, and COL17A1. Manfred Kayser and his team of the Erasmus University Medical Center in Rotterdam, the Netherlands, used Magnetic Resonance Imaging (MRI) of people’s heads to map facial landmarks and estimate facial distances."

And when the cops need to get a picture of the suspect, they won’t have to ask eyewitnesses to give descriptions to a sketch artist – they’ll just ask the technicians to get a mugshot from the DNA. That, at least, is the potential of new research being published today in PLOS Genetics. In that paper, a team of scientists describe how they were able to produce crude 3D models of faces extrapolated from a person’s DNA."

    Criminal investigations is a niche use. The broad use and real revenue would be an adult picture of your unborn child or new baby. Future parents already pay $300-400 for 3d sonograms of their fetus. Imagine seeing your new baby's face each year from two to twenty years old.

    You could even sequence a couple individually and show the full range of boy and girl facial outcomes with probabilities. Right now they can use some morphing techniques as a kludge but genetics could be MUCH more predictive.

    • That's a great application! I'm sure people with the money would spend a small fortune on that even if it's a novelty.

      I was talking about it with my wife and she had a really good extension: sperm banks. Right now you get some written information about the donor, but can't get anything really detailed. Imagine if you could offer women the opportunity to see what their children might look like based on their DNA and that of the donor. I'm sure that would be a very popular value-added service.

    • The broad use and real revenue would be an adult picture of your unborn child or new baby

      And even if the technique does not work, you will make money for 20 years before anyone notice this was a scam. How clever!

    He seems to say he can do a match on 20 genes.... but that he will be able to soon do over 200 ? So what are those 180 other genes matching for ? Because either what he does today is poor and the 200 are needed or the methodology might even be total crap, or the 180 are not needed if he gets already good result today.

    And look at the face it is so generic alone in my building it could match a sizeable part of the population. I would not be surprised to learn that it is snake oil.
  • But that's not how Dr. Claes sees the technique being used in a criminal investigation.

    Yeah, I can see it being used in a lot of ways. A lot of unsavory ways.

    Digital face construction from DNA is used to identify people for as simple a crime as throwing a used chewing gum on the street.

  • One very useful outcome is that this could prevent false accusations, false arrests, false inditements and false convictions. The focus tends to be on finding the bad guy but it is even more important to avoid convicting the innocent person. DNA testing does a lot to overturn the convictions of innocent people. This could stop the process of false convictions even earlier.

    We know that Facebook has a vast facial recognition database so good that it can recognize you when your face is hidden, that the FBI has built a millions-strong criminal facial recognition system, and that Googleâ(TM)s new Photos app is so effective at face recognition that it can identify now-adults in photos from their childhood. But now facial recognition is starting to pop up in weird and unexpected places: at music festivals (to identify criminals); at stadiums (to weed out âoesports troublemakersâoe) and at churches. Yes, churches.

  • If the system can interface with a database of face data it would still help to reduce the number of possible suspects by a huge amount. Then by a process of elimination and cross referencing with other data, such as phone meta-data, geo-location etc., it could allow for the very rapid identification of the average, impulsive, criminal who's crimes are opportunistic or reactive. The covert collection of DNA from the small list of final suspects would be all it would take to be sure the correct person had be
