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

現在一種叫做DNA的技術，FINA分型可以把犯罪現場分析提高到另一個水準。

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.

調查人員多年來一直使用的DNA側寫法，他們試圖將犯罪現場的DNA與系統中已有的記錄進行匹配。

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

有了新技術，基因資訊就不需要比對、比較了。

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

它利用自身的DNA來預測某人可能的樣子。

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

這個過程並不便宜，而且還存在隱私問題。

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

比如說，如果你被列入ancetry com，你和嫌疑人的關係就會被發現。

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

但這正在改變一些調查的方式。

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

這項技術叫做DNA FINA分型，由帕拉香蕉實驗室研發。

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

僅僅從一小部分DNA樣本中，他們就能創造出一個人的綜合形象。

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

你認為這項技術會對法醫產生什麼樣的影響？

Long term.

長期來看。

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.

在這裡，我們有另一條可以探索的途徑，如果我們在路上遇到了死衚衕，我們基本上是帶來了全新的法醫DNA分析方法。

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.

傳統的法醫DNA分析只看犯罪現場的DNA能否與我們已經確認的嫌疑人或數據庫相匹配。

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

但如果你沒有找到匹配的對象，它也無法告訴你其他的事情。

We can generate leads just from the DNA.

我們可以從DNA中產生線索。

That's at that crime scene.

這是在那個犯罪現場。

Para bombs started to offer forensic services.

準炸彈開始提供法醫服務。

Tow law enforcement in 2015.

2015年，拖動執法。

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

此後，他們已經協助處理了40多起案件。

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.

我們工作的很多案例，原來他們有一些資訊是讓他們往某個方向走的，而我們的資訊完全是重定向的。

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

你知道，你不是要找一個這樣的人。

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

你要找的人這個很不一樣的描述，一旦他們支點，開始走這條路，就能找到那個人。

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

我們的DNA攜帶著針對個人身體特徵的特定指令集，只需少量樣本。

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

對位鍵可以從數以萬計的基因變異中提取，預測一個人的長相。

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

所以基本上，我們是在預測人臉在不同面部維度上的落點，我們稱之為面部空間。

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

所以這一切都只是來自於我們對人臉數據的一些計算。

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

而隨著數字的變化，它顯示出不同的可能面。

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

所以，可以預測到的可能面孔有很多種。

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.

這看起來像你，也就是說，這可能不是我的駕駛執照影像，但如果我非常接近完全，是的，服務費用約3000美元，但結果可能意味著當局花費更少的時間和人力來解決一個案件。

The composites do have limitations, though.

不過，複合材料確實有侷限性。

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

例如，DNA並不能顯示一個人的年齡。

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.

所以為了彌補，帕拉邦根據犯罪時間的長短來估計這個人現在的模樣，它只是一個指南，僅憑表型是不能定罪的。

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

這就是科幻電影裡的那種東西，你知道的。

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

我的意思是，國際泳聯的打字絕對是很科幻的。

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

有沒有像隱私方面的問題，或者這一切的道德含義是什麼？

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.

好吧，用DNA國際泳聯分型是昂利預測的事情，人每天都會在眼睛外面公開，染髮顏色。

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

我們不看任何醫療資訊或類似的東西，然後與基因譜。

All the research that we dio is public information.

我們所做的所有研究都是公共信息。

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.

除了國際泳聯打字外，基因譜系也被用作另一個工具，para bon和執法機構正在使用它來抓捕罪犯和結案。

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

通過搜索DNA的公共數據庫，家譜學家可以向後工作，一個家庭樹縮小搜索嫌疑人前進。

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

冷門案件的數量會減少，而且活躍的案件也有可能更快地解決。

Cases they even become cold.

案例他們甚至變得冷漠。

Case Exactly.

案件正是。

Cases won't have to go cold.

案件就不用冷處理了。

Mm hmm.

嗯哼。
