Domestic DNA analysis reveals our most hidden secrets.

(Music)

It is a promise to which many simply

We have not been able to resist.

Send your DNA and discover secrets about your family,

Your ancestors

And even your health.

-The something really new every day appears,

And this is something truly new.

But to what extent are homemade genetic tests reliable

And its percentages of ancestry, supposedly scientific?

Should we worry about our privacy?

What can be the unforeseen consequences

When do we reveal the secrets of our DNA?

(Music)

In the district of Olympia, Washington,

A woman has discovered

how unpredictable consequences can.

Chelsea Rustad, specialist in information technology,

It is an avid family historian.

In 2015 a DNA test was made

With the most important company of genetic analysis,

Ancery DNA.

Many people end up doing it,

Because he wants to know more about his ancestors.

But then, more than are not expected to arise

And that was exactly what happened to me.

The results of his test indicated

that the ancestry of Chelsea was mainly Norway and German.

Then, as I also felt

to find new relatives,

Chelsea downloaded its ancestry complete report

and uploaded it to a free website GEDMATCH.

It is a page where anyone can search for coincidences,

regardless of the laboratory in which the analysis is done.

Gedmatch showed Chelsea

All site users shared DNA with her.

It is an interesting experience and a lesson of humility

See all those connections

and realize the large number of people

with which you share a percentage of your DNA.

In Gedmatch, Chelsea found one aunt who already knew,

But to no other new part.

He closed the session and never entered that website again.

Three years later, on the night of May 17, 2018,

Chelsea receives an unexpected visit.

I looked for the Miraillay I saw two policemen waiting outside

And when I opened them, they told me they were detectives,

who investigated a homicidiode case thirty -one years ago;

A case that had never been resolved.

Had reached her

Thanks to the DNA file he had published in Gedmatch.

Before his astonishment, they told him

that their DNA had led them to a suspect.

Actually, it was very shocking and very hard to assimilate.

All they told me was a story of horror.

(Music)

In a sinister turn,

The hopeful search for close relatives of Chelsea

became the search for a murderer,

Someone with who is related.

Although its history is not frequent,

shows that DNA analysis companies faithfully comply

One of his greatest promises:

connect with relatives.

(Music)

Home genetic tests,

possible thanks to the laws of inheritance,

They have become an industry

valued in billions of dollars.

We inherit the adde our parents:

Fifty percent of the mother and fifty percent of the father.

And they inherited him from his parents.

And his parents, of course, of his.

Each parent gives us approximately

Fifty percent of our DNA.

And the same for them and their parents;

so that the amount of DNA inherited from any ancestor

It is reduced by half with each new generation.

We also share DNA

With other people that have the same ancestor:

brothers, stepbrother, cousins brothers,

second cousins, etc.

(Music)

The way in which the genetic test determines the kinship is

Comparing people's DNA.

The shared amount is measured in a unit called Centimorgan.

The more centimorgans two people have in common,

more closely will be agreed

And, the less they share, the farther their kinship will be.

But it is not always possible

Determine with a domestic genetic test

The kinship with someone,

simply counting centimorgans,

because they are in the same range of values.

For example, the same number of centimorgans could be shared

With a cousin and an uncle grandfather.

Just because you share a amount of DNA,

It does not mean that you can know security

What relationship do you have with that person.

It is only a probability, a spectrum of potential relationships.

June Smith lives in New Jersey, not far from Philadelphia.

In 2018, one of the DNA tests was made,

hoping

A mystery that had accompanied him a lifetime.

For many years, June investigated its roots.

At 16, when he lived in Philadelphia,

The woman she thought was her mother to reveal a secret.

He told me: "Your mother was a white woman."

And me: "A white woman?" That struck me a lot.

His biological mother was called D'Amico.

June had never met his father's identity.

When June was done, with ancestrydna,

marked a box for contact

With any other client with the one who shared DNA.

Although he knew Anne, his mother, had died,

There was another person who wanted to find,

desperately.

When he investigated his life, June discovered

that Anne had given Luza another mulatto daughter,

of a different father.

A girl named Joan Mosses.

The largest stepbrother of June.

I started to investigate.

I looked for Joan Mossese in all web pages

and in people seekers.

But I never found her.

One day, June received an ancestry message

in which they informed him that he had a new conscience

With an upcoming relative,

A woman named Sigrid Gilcrest.

She had also grown in philadelphia.

He was the only child of a black couple

Very active in the Civil Rights Movement.

But when Sigrid turned 16,

His mother revealed a secret that he had hidden him until then

He told me that she was adopted,

That my mother was Italian and my father, black.

It was devastating.

I had no idea.

In the following years,

Sigrid never contacted Conninguno from his biological relatives.

Until one day, just when Juan was done with ancestry,

As a chance, Sigrid also had her.

Ancestry informed the two women that they shared

one thousand six hundred forty -concentimorgans.

Maybe they were sisters.

June kept wondering

If Sigrid could be a closest relative.

The two women agreed to speak on the phone.

She told me: "I have three questions to ask you."

I replied: "Wow."

I asked: "Did they adopt you?" He said: "Yes."

Me: "Are you mulatto?" And she: "I am."

I said: "For a casual, was your mother -called Anne D'Amico?

-I said: "Yes, that's what the biological mother is called."

He asked me: "Are you Joan Mosses?"

And I said: "That is my name in my birth certificate."

-I said: "My God, you are my sister; you are not my cousin."

We cried and I couldn't believe it,

I was talking with my older sister.

(Music)

Yes.

-He as we met usual.

The feeling of spiritual connection was indescribable.

(Music)

-Necorating my sister gave me a sense of belonging.

It gave me the opportunity to say we brought the same blood. '

-I see it.-Does it look like me?

-Yes.-Mira esa barbilla.

-Yes.

-It is wonderful to have an older sister.

-I don't like to be the oldest, but I love having a little sister.

-Ella me comprende.-Yes.

The domestic genetic tests can put people in contact,

like Sigrid and June,

Thanks to a surprising new discovery about DNA.

We have known for a long time

that the DNA molecule that is practically

In all the cells of our body,

It contains the code that directs our lives.

The code is transmitted by chemical bricks,

called bases, known as A, C, G and T.

They form pairs

that create the famous structure in the form of the DNA staircase.

Frylera is necessary

of three billion these base pairs

To form our complete genome.

But since 2003,

When scientists managed to read, for the first time,

all that bases,

They discovered something surprising

In a ninety -nine percent of them.

If you look at any two people,

Most of your DNA is exactly the same,

because all the things that keep us alive,

All those things,

They have to be the same, they cannot change;

Otherwise, it would not work.

But there are parts of our DNA that do change.

Some of them are called unique nucleotic polymorphisms,

or SNP.

They are points where most have certain base pairs;

But some have others.

So, instead of trying to identify

the three million pairs of a person's bases,

The domestic genetic tests do it is much cheaper

and fast.

They only analyze the SNPO variable parts of your DNA.

Generally, about seven hundred thousand.

Compare the changing DNA of people is

Sabersi's most effective way are related,

because, when they coincide,

All the DNA between them is also usually identical.

And when the DNA segments coincide,

That is the unmistakable sign of a certain degree of kinship.

Through shared DNA analysis,

Consumer direct genetic tests obtain

A quite precise image between individuals.

Familytrateedna, in Houston, is

One of the four most important companies

that performs genetic analysis.

As in almost all of them,

The basis of your complexion is the SNPS reading technique.

And here it is:

A small piece of glass, called DNA chip.

It contains hundreds of thousands of tiny accounts.

Each of them carries a small fragment of DNA,

called molecular probe.

We put the DNA of a subject in the chip

And the DNA fragment of the subject that coincides with that little probe

joins.

Once united,

A fluorescent marker makes visible

The identity of the variation in the DNA sequence.

For example, if you have one A, you will see green.

If you have a G, you will see red.

SNP Data allowed Laboratory

know how much DNA they share

customers who want to know them family coincidences.

The business page of the businessmen shows

Your matching list.

Will show you all the people with whom it is related

and the degree of estimated kinship.

(Music)

But sometimes,

That list of coincidences can reveal painful truths.

With the appearance of DNA tests,

Anonymity and take secrets to the grave

It is no longer possible.

That was exactly

What Dani Shapiro would discover a conjocly.

Novelist and memoir,

He had published his childhood story

with his Orthodox Jewish family in New Jersey.

And about his parents, Irene and Paul.

I was very very close to my father, much more than my mother.

He worked in the New York Stock Exchange

And sometimes he stayed with him to eat.

When he left, he opened his arms and told me: "Hello, honey.

Give me a strong hug. "I'm going to cry.

I worshiped my father.

From his earliest childhood, he aroused all kinds of comments:

"You do not seem Jewish, it is impossible to be Jewish, you are not Jewish.

Did your mother have an adventure the Swedish dairy?

Is Shapiro your married name? "And it would continue.

A day of 2016, her husband, Michael Merwin,

He decided to take an ancestry adnen.

Without thinking twice, Dani also made it.

She knew that her two wereasquezíes parents,

or descendants of Jews from Eastern Europe.

A few weeks later, they received the results.

We open them and he said: "Wow, according to this,

you are around fifty percent Asecnazí,

from Eastern Europe, and the rest of Western Europe:

French, Irish, English, Swedish, German ... "

My only answer was: "Ah, well, surely there is some mistake."

But, a few days later, my husband arrived and said:

"You have a cousin in ancestry.com,

a face brother we don't know. "

Looking for clues, Dani got in touch

With someone who knew it was a biological relative.

I have a steeplet much greater than me,

my father's first marriage.

I remembered that some years before

The test had been done in another laboratory

And I sent him an email asking him:

"Do you have the results of the DNA test you made?"

And he sent them to me.

Dani passed the archive of his stepsister

to her husband, who, through Gedmatch, verified

How much DNA Dani shared with her.

Discovered the truth.

He told me: "You are not sisters." And I: "No, stepsisters,

That is what we are".

And he told me: "You are not sisters, you are not families."

And it was at that time when all the pieces began to fit.

I thought: "Ok, if he is not our parent,

he is not my father".

They hid something very very important.

And I felt that my identity was done ...

... pieces.

His two parents had already died,

But Dani recalled that his mother, on one occasion, commented

that had cost him a lot to get pregnant,

and mentions a fertility clinic in Philadelphia.

Dani and her husband located

The cousin brother that had appeared in ancestry.

His uncle was Dani's biological father.

Retired doctor,

had studied at the Philadelphia Medicine School

And he had been sperm donor in his clinic.

Dani searched on the Internet and found him in a video of his conferences.

I knew what I was seeing.

I remember that I got up, I entered the bathroom

And I looked at my face in the mirror for the first time after having seen him.

For the first time in my life, I understood my face.

Dani felt obliged to write a new book

About family, identity and personal experience.

Your title, inheritance.

The book is dedicated to my father.

Sometimes someone asks me 'What father?'

And me: "Are you a joke?"

My mother wanted to have a child

And I think it didn't have to be easy for my father to accept that situation

and be willing to be genetically replaced,

Because that's what happened.

They said: "One of us will be the biological father of this child

And the other, no.

And nobody will ever know, except us. "

(Music)

But Dani has not been the only one.

It is estimated that about one million people have discovered,

through home -made DNA tests,

That the man who raised them was not his biological father.

Or that they had a brotherhood that they knew nothing.

Sometimes, what comes to light are even darker.

In 2018, in the state of Washington,

The secret that Adde Chelsea Rustad helped to reveal

It could be the key to clarifying unresolved case

For thirty -one years.

It was very disturbing; I was distressed.

Just a monster could do that to someone.

On November 18, 1987, two young Canadians,

Jay Cook, twenty years old,

And his girlfriend, Tania van Cuylenborg, from eighteen,

They left their hometown, a neighborhood of Victoria,

In British columbia,

in the direction of Seattle,

To make a message for Jay's father.

Six days later,

The body partially naked Tania was found

In the gutter of this Skagit County road, Washington.

They had shot him in the head and there was evidence of rape.

Two days later, about a hundred kilometers away,

In Snohomish County, under this bridge,

Some hunters found Jay's body.

They had strangled him with a rope and a dog necklace.

They had also hit his head with a stone.

They were two completely innocent young people,

that had been kidnapped and brutally killed.

During the investigation,

Police found in Tania's body

Potentially valuable evidence of your aggressor.

They were examined in the laboratory,

with the reference test used to identify through DNA.

The test only analyzes

about twenty genome fragments,

in which a chain cortade letters,

For example, g a t a repeats again and again.

They are known to have short tandem repetitions.

Scientists can count the number of times they are repeated.

Those counts varies by people,

Like the ridges of a fingerprint.

It is a very powerful technique, because, with enough fragments,

You can get a very high identity coincidence,

for those small differences.

But, as with a fingerprint of the scene of a crime,

A repeated short sequences profile

from the crime scene,

It will only be useful if an existing profile coincides with

in the police database.

For decades, the profile of this case did not match

with that of no police acquaintance.

Therefore, it was never resolved.

Until the day

in which Chelsea Rustad climbed DNA analysis to Gedmatch.

They became the indication that, finally, led to the police

to a key track to solve the case.

(Music and police cars sirens)

Chelsea's experience ended up becoming news.

But most people who do DNA tests

You just want Sabercuá them are their roots;

a seemingly simple question,

That, often, has its own mysteries.

Do not open anything we ask you.

These fourteen people are about

to live the experience of the genetic offspring.

Many of the boys with those that I have grown are

in the same situation.

We do not know our ancestors.

We assume, quite sure,

that our ancestors lived slavery and things,

But we don't know where we proceed from.

Kerry Richardson participates in a research study

from the University of Westchester, in Pennsylvania.

We have a research protocol to collect data for this project.

The study is directed by two communication teachers,

Bessie Laton and Anita Foeman.

The question asked is

'How do Adna's tests affect our idea of who we are

And to our ability to understand what makes us different? '

When we have the results, we will meet.

The idea is that we listen and communicate.

For this Proyect,

Anita was inspired by her experiences as a formator in diversity.

It occurred to me that knowing our adnera a very interesting way

to address the theme about race and diversity,

without people getting defensive.

And so it has been.

-We don't identify with Africa. We say we are black.

We separate from that where we come from.

In an earlier test, Tyquine Golden discovered

that had western Africa roots by 80 %

and British, in 20 %.

You have everything.

With your today with FamilytreeDna,

He hopes to know more.

My suspicions lead me to say that, possibly,

Twenty percent was integrated into our DNA during slavery

and that that could not have been voluntary.

-As African -American, I think, when you think about your origin,

It is difficult to accept your white ancestry,

That, often, was due to rape and abuse.

But it is part of your story.

So you have to face somehow

and understand it.

It is part of how you got here.

-I don't want to hide from truth; it doesn't matter how hard it can be.

The time has come to collect the DNA ...

-Gore it a little, to collect more.

... and send the Houston samples.

But how do they get

Fast Family TradeDNA tests

breakdown the ascendencies?

It is also a technique based on the fragments of our DNA

that vary more frequently between people.

(Music)

The company compares those of people

of its so -called reference groups.

They are live people DNA has been analyzed

and share variation patterns.

Scientists have observed

which are characteristics of the regions in which they live.

These patterns are collected in a database,

But to what extent do the subjects analyzed represent well?

They are its origins, according to their database,

But, if something is not there, they can't assure you

which is to be part of your ancestry.

Homemade genetic tests have less data

of people of African and Asian origin,

than people of European descent.

The majority of genetic analyzes that have been carried out are

of Europeans of the North Atlantic.

It is a fact

that our reference databases are biased.

-Why do we not take all a minute and open the results

To take a look at the map for the first time?

Familytrateedna has given Nick Pasvanis,

whose parents remembered his ancestors from Greece,

Germany, England and Scotland,

A very detailed breakdown.

-I

That is something that awaited me.

I've always felt a little European street dog '

And that is, just, what my map says.

-When I saw him, I wondered where he came from,

If I'm really black.

And I am from Western Africa in 94 %,

So, I'm quite black.

But the so -called African bubble 'by Richardson

It offers few details.

The bubbles of Hanna Vishmany Viola Wan, both born in China,

They are even bigger.

I only have two giant bubbles,

of 'you are overrays, as if I didn't know!

-The people with huge bubbles considered basically

as minorities.

-And it is unfortunate, because it perpetuates a form of Eurocentrism

that has marked our science

And that is the foundation of the idea, the false idea,

of white supremacy.

It is like how inequalities are accentuated

which currently prevail in all science.

especially in genetics.

-And 23 % of the European southeast, with outstanding Italy and Greece,

That was never on our radar.

But there is another problem with the form

in that genetic analysis calculate your ascending.

The DNA of the people who lived in a place a long time ago,

Your ancestors,

It could be different

of the DNA of the people of the reference groups

that live today.

And that is because, for centuries,

People and their DNA have been staring around the world.

Really, you have to overcome

The ballast of the idea of static human populations,

that there are Irish genes, Italian genes, Nigerian genes

and Zimbawenses genes.

That is not the way human evolution works.

The idea of immobility feeds the racist paradigm,

It feeds the 'you against me', the 'we against them.

However, it is true

that some variable genetic patterns are more frequent

in some places that in others.

-There are several clues that can link you

with specific areas and regions where your ancestors evolved.

Companies do it better than they can,

With the data they have.

-That is the reason why

All DNA analysis companies are trying

add your databases to more different populations,

so that, when you cannot mean your origin exactly,

They can approach so much to Ellacomo is possible.

Bessie and Anita have discovered that, regardless of their failures,

DNA tests to know your ancestry

They help people think about their roots

and better understand human diversity.

-The northern Africa, the Middle East, Western Europe, but I ...

-He does most people in their history

In relation to other people,

within the framework of the history of human migrations.

Most perceive a positive experience.

The results of Golden, Familytrateedna,

The ones he received from Ancestry are very similar.

I can't keep ignoring my DNA part of Ireland and the United Kingdom.

-A question, do you think they are authentically black like her?

-I don't think there is a lot of difference.

-They sat down and had a conversation about the race,

That was fun, exciting and unifying.

And, if that happens more and more, what are the possibilities?

But no matter how difficult it is to determine your ascending,

The most complex challenge that genetic analysis have assumed could be

Evaluate the risk of genetic diseases.

Because, as regards the precision of these tests,

What is at stake could not be more important.

We all run the risk

to develop potentially mortal diseases,

But, for some, that risk is greater,

due to variations in their genes,

deviations from the prison sequences of AES, CES, GES and TES,

that form the genetic code that directs

Protein production,

The essential molecules that make our body work.

It is hard to believe that the change in a single letter

In that gigantic chain three billion letters

It can affect a human being so deeply.

But when one of those critical fragments occurs

in which this specific change occurs,

The protein simply stops working.

Now, several of these tests offer

Genetic health analysis analysis.

But to what extent are they reliable?

Most of these studies studies Variations of concrete DNA

and ignore the rest of the genome,

where other risks could be taking;

risks that inevitably will ignore.

An example,

The controversial 23Andme test, of breast cancer risk.

Examine two genes called BRCA,

that encode the proteins that control cell growth.

But certain variations of base pairs make

that the Brca Mutan genes,

making some cancers, such as pancreas, prostate

and especially for ovary and breast,

Be more likely.

Scientists have documented

about four thousand variations of this type.

23Andme markets a DNA variation test

which detects three of them.

Their presence, among others, makes women

A very high risk of breast cancer.

These three variations are reliably detectable

Through these tests

And the three most frequent times

among women who have Jewish Jewish.

Jessica Algazi, a 52 -year -old lawyer from Los Angeles,

He has three Asecian grandparents.

(Music)

In 2018, the Brcade 23Andme test was done,

Without being able to suspect, a priori, that his life would change.

One day, when I was playing golf,

He received an email.

I received the results

While traveling the campocon my golf cart;

And when I saw them, I thought 'My God, I can't believe it.'

The genetic analysis report

that had a variation of the BRCA1 gene,

that made highly likely

that develop ovarian or breast cancer.

A second test,

Made by a DNA laboratory specialized in BRCA tests,

He confirmed it.

Although he had no cancer, Jessica made a decision.

My gynecologist told me: "Jess, you have to do it,

You have to remove them ovaries and tubes;

And you need a double mastectomy immediately. "

I am very grateful to have found in time.

I have been able to stop before getting sick.

I will be eternally grateful to the 23Andme people,

For giving me this opportunity.

Possibly, they saved my life.

But most women with variations in BRCA genes

They have none of the three variations that 23andme detects.

Women like Pamela Munster.

It is oncology in San Francisco and a breast cancer specialist.

I have the BRCA1 gene.

They do not have an asquenazí Jewish ancestor.

In 2010, Pamela took the BRCA test.

I discovered that there was no great risk suffering from breast cancer

and that, according to the results,

The probability was also quite low.

But in 2012,

Pamela diagnoses breast.

For the appearance I had in the microscope,

I had the feeling

that this cancer was related to a mutation of the BRCA genes.

To confirm your impression,

Pamela analyzed her DNA in a specialized clinical laboratory.

Not only does it examine adnaislado variations,

Also, all genetic base pairs,

A process known as sequencing.

They analyze all BRCA genes;

Recall that there are eighty thousand pairs of bases

And they can tell you if the lyrics are there if it is not.

Pamela was right: he had the BRCA2 mutation.

But it was none of the three variants

which detects the 23Andme test.

It was another of the thousands that exist.

If you just want to know who you are related,

The 23 Andme and Ancestry tests are very good.

If what you want to esssaber if you have a Brca gene

and you are at risk of breast cancer,

That type of proof is not ideal.

But in 23Andme they assure us

that his BRCA test has alerted three thousand people

About its risks of cancer

and that the choice of those threevariants is justified,

because they imply a very high risk.

-The risks involved in these three variants

They are demonstrated.

And studies show

that almost half of the people carrying one of those variations

does not know.

-It's very good that someone

that does not even suspect that mutation carries

can discover domestic genetic tests,

But it is not so much

If you think you have undergone an exhaustive test,

because that is not it.

It also worries

how the data of the users of these tests are used.

In 2018, 23Andme agreed to share with glaxosmithkline

anonymous information on millions of customers,

To use it in the development of new medications.

23Andme says

that about 80 % of their clients gave their consent

so that their data could be used in research.

Most also completed health questionnaires,

that allow establishing valuable relationships

Among his genesy his clinical history.

What can be done with that information is amazing.

Although the potential benefits of the agreement seem clear,

There are many who believe they raise ethical problems.

-You are paying for giving your data a company

that will capitalize them covertly

and of which you will not benefit.

When there is such a new technology, it is impossible

that consumers can understand all their implications,

Because they are too recent things.

To what extent are the data safe

Of the twelve million customers of 23 Andme?

We do not sell or share their data

With no insurance company companies, without their consent.

Federal laws prohibits most companies

Use genetic data to make decisions in the workplace.

They also prohibit

that health insurance companies use

To change or deny insurance.

But companies that sell life and disability insurance

They can use them freely.

While 23 Andme and Familytree spoke with us

On these issues,

Ancestry declined participating in the documentary.

The risks inherent to new technologies,

Often, they are only obvious.

Chelsea Rustad could never imagine

that your DNA test would lead to the police

even a dangerous suspect of murder.

They found it through a new research technique

arising directly from the rise of domestic DNA tests,

called genetic genealogy.

Before it was used to resolve crimes,

They were used by people who were looking for their biological parents.

One of the pioneers is a lawyer with retired patents,

called Barbara Rae-Ventor.

I was part of all this.

Because he worked for adopted people looking for their parents.

For those adopted, DNA has been very important,

because it will find biological relatives

only through documents

It is very difficult.

Barbara begins the person adopted

with others of its Coincidences of DNA.

Then, looking in the records, it locates more relatives.

The objective is

find an ancestor that connects them all

and to point directly to the biological father.

In 2017,

Californiale detectives asked Barbara

to try to solve a very different type of mystery,

One of the most famous without solving in the country.

It was suspected that the so -called Golden State murderer '

He had committed at least thirteen murders

and more than fifty violations

during the 70s and 80s.

Police had their ads for a long time,

But I had no ideade who could be.

Barbara agreed to help them.

From the adde the crime scene,

They created a profile of the genetic variable part

And then they uploaded it to Gedmatch.

Barbara developed a family tree the relatives found.

Finally, he concentrated on a man named Joseph Di Angelo.

Di Angello, an expolish,

I had never been among the suspects.

Police picked up his Adny did a genetic test.

The result was a perfect coincidence

with the DNA of the murderer of Golden State.

-Sessinate in the first degree. How is it declared?

In June 2020,

Joseph Di Angello declares himself of thirteen murders.

-Guilty.

He was sentenced to life imprisonment.

When Di Angelo's arrest occurred,

Detective Jim Scharfse was amazed to discover

what could be achieved by genetic genealogy.

Quickly, he thought of Tania and Jay.

He contacted a computer scientist

with whom Virginia had worked,

Steven Armentrau.

Do I enter the number aquío am I a calculation?

Steve's company has developed technique and software

which can screen hundreds of thousands of DNA variations.

First, we have to convert the DNA of the crime scene

to a compatible format.

Jim gave us the approval of a Thursday

And on Friday we had uploaded it Gedmatch.

Steve had associated

With a specialist in genetic genealogy,

from California, Cece Moore.

On Saturday morning I got up

And before even putting my lenses,

I opened my laptop to see if we yattered a list of coincidences.

And so it was.

Gedmatch had two people

who shared about 3 %with the suspect unknown.

There were two people who shared about 3 % DNA

with the suspect;

Enough to be its second cousins.

Those second cousins would have shared

A pair of great -grandparents,

And that are not so far in the family tree.

In genealogy,

It is almost always possible to track great -grandparents.

One of CCE's main coincidences was

Chelsea Rustad.

The other, a cousin that has never been publicly identified.

Both shared the suspect,

But they didn't share it with each other.

That meant

that represented different branches of the suspicious family tree.

I was very lucky.

I found the obituary of a woman who was carrying the last name

that the family tree had just seen

of the family of the other matching subject.

That told me

that a woman from this tree and a man of this other

They had married, hopefully, they would have had children.

Cece knew that, if they existed,

They would carry a combination of ADNMUY similar to that of the suspect.

The couple had had four children.

We were very lucky

that there was only one man in that family,

Because genetic genealogy applied to a person, only one.

And it was William Earl Talbott II.

(Music)

At the time of murders, Talbott lived a few kilometers

of the bridge where Jay Cook's body was found.

At that time, I was 55 years old. It was a truck driver.

Police watched him.

They wanted their DNA to see if it coincides with the crime scene.

One day, they were lucky.

A disposable glass fell from his truck.

Jim Scharf took the Criminalistics Laboratory Vasoal

of the Washington State Police,

to do a genetic genealogy test.

Lisa Collins, the laboratory director,

He asked him to wait for the time to do the tests.

Lisa returned, the report gave me, he told me: "Jim, it's him. He coincides."

I could'nt believe it.

My eyes filled with tears.

I shouted: "Wonderful!"

We finally took this type.

May 17, 2018,

William Earl Talbott II was arrested

and accused of first degree murder

for a crime committed thirty -one years before.

That man could be identified

Not because he did a DNA test,

but because it was made a distant relative,

Someone whom I didn't even know.

In June 2019, the jury pronounced its verdict.

We, the jury, declared the accused,

William Earl Talbott II,

guilty of the crime of first degree murder.

Talbott was the first suspect

identified by genetic genealogy,

condemned by a jury.

He was immediately sentenced to two consecutive perpetual chains.

The researchers have told me many occasions

that they would not have been so far without my DNA

and that the casing would have been resolved.

From the condemnation of Talbott,

The team has used genetic genetics

to identify more than a hundred suspects.

But the simple fact of being identified by a genealogist

It is not enough to be able to arrest someone.

To be able to carry out a detention,

We have to obtain the DNA confirmation

through a repetitive short DNA sequences test.

Even so, for the most critical,

The use of genetic genealogy

by security forces

It raises a privacy problem.

-Will we stop people who have committed atrocious crimes?

Yes. Pero ¿qué perfiles de ADNse investigan?

We have never heard

about failed attempts to find suspects,

nor of data safety violations

or privacy

that occur along the way.

The genetic genetics team assumes

that those fears are exaggerated.

It is the users who decide

If your DNA can be used for investigations.

When you do a 23Andme or ancestry test,

Your DNA is in its private database.

But the regulation is scarce and the laws vary.

In 2019, Familytree had to apologize

for allowing the FBI to look for its database

To people who shared DNA

with a sample of the scene of a crime,

without the permission of your customers.

Both family and gedmatchahora assure

They only do it when they say their explicit permission.

Another concern: DNA companies,

For the consumer,

Like all companies that collect data,

They are vulnerable to computer pirates.

However, it is obvious that risks do not deter.

No one forces anyone to get a DNA test.

If your paranoiay your fear of 'Big Brother'

It is greater than your interest in reading the medical and history books

that there are writings in your cells,

So, I think you shouldn't take the test.

-There are beauty to discover and investigate where you come from.

The phenomenon of consumption DNA has changed

the life of many people,

revealing the secrets

hidden in the depths of our cells.

But do costs and risks exceed its benefits?

I want to know if you run the risk of developing Alzheimer's

When there is absolutely nothing I can do about it?

Maybe not.

-With these popular adunt tests now

There are many probabilities that all those

to those who have hidden a secret of this nature

end up discovering it.

Our heart and our mind know very well

How to accept that we ask us to face.

-I think the rise of DNA tests in the last twenty years

has opened the minds of people

to the possibility that they share more with other people

what they thought they shared.

-That 1 % that makes us different, in reality, is only

The beautiful diversity of the natural world.

It does not mean that a genotype or genome is better than another,

Only they are wonderfully different.

-How many more evidence we do,

more we see how connected we are among us

And, perhaps, if we feel that we are in connection,

Let's treat each other a little better.
