  • For decades, DNA has been used in criminal justice to identify suspects or clear people who've been falsely accused.

  • Now a type of technology called DNA, FINA typing could take crime scene analysis to another level.

  • In DNA profiling, which investigators have used for years, they try to match DNA from a crime scene to records they already have in their system.

  • With the new technology, genetic information doesn't need to be matched or compared.

  • It uses the DNA on its own to predict what someone could look like.

  • The process isn't cheap, and there are privacy concerns about it.

  • If you're listed in ancestry com, for instance, your relationship to a suspect could be discovered.

  • But this is changing the way some investigations air carried out.

  • The technology is called DNA FINA typing, developed by Para Banana labs.

  • From just a small sample of DNA, they can create a composite image of what someone could look like.

  • What kind of impact do you think that this technology will have on forensics?

  • Long term.

  • Here we have another avenue we could explore if we run into dead ends along the way, we're essentially bringing in entirely new ways to analyze forensic DNA.

  • Traditional forensic DNA analysis looks just at Can this DNA from a crime scene be matched to a suspect we've already identified or to a database.

  • But if you don't find a match, it couldn't tell you anything else.

  • We can generate leads just from the DNA.

  • That's at that crime scene.

  • Para bombs started to offer forensic services.

  • Tow law enforcement in 2015.

  • Since then, they've assisted in over 40 cases.

  • A lot of the cases we work, it turns out that they had some information that was leaving them in a particular direction, and our information completely redirects.

  • You know, you're not looking for a person of that description.

  • You're looking for person this very different description, and once they pivot and start going down that road, they could find that person.

  • Our DNA carries a specific instruction set for an individual's physical characteristics, with only a small sample.

  • Para bond can pull from tens of thousands of genetic variance to predict what a person looks like.

  • So basically, we're predicting where the face falls on different facial dimensions in what we call face space.

  • And so this all just comes out of some math that we do on face data.

  • And as the numbers change, it's showing different possible faces.

  • So there's a wide variety of possible faces that could be predicted.

  • That looks like you, that is, This may not be my driver's license image, but if I were pretty close exactly, yeah, the service costs about $3000 but the results could mean authorities spend less time and manpower to solve a case.

  • The composites do have limitations, though.

  • For instance, DNA doesn't reveal a person's age.

  • So to compensate, Para Bon estimates what the person would look like a present day based on how long ago the crime was committed and it is simply a guide, the phenotype alone cannot lead to a conviction.

  • It's the kind of stuff from a sci fi movie, you know.

  • I mean, the FINA typing is definitely very sci fi.

  • Are there any like privacy concerns or what are the moral implications of all of this?

  • Well, with DNA FINA typing were Onley predicting things that the person makes public every day when they go outside their eye, color their hair color.

  • We're not looking at any medical information or anything like that, and then with genetic genealogy.

  • All the research that we dio is public information.

  • Along with FINA typing genetic genealogy is being used as another tool para bon and law enforcement agencies are using to catch criminals and close cold cases.

  • By searching a public database of DNA, genealogists can work backwards and a family tree narrowing the search for a suspect going forward.

  • The number of cold cases will decrease, and also active cases can potentially be solved more quickly.

  • Cases they even become cold.

  • Case Exactly.

  • Cases won't have to go cold.

  • Mm hmm.
