The public institutions represented in this drama are not related to real ones.
It's time.
Let's go back in.
On a day like this,
Where did Dr. Yoon Ji Hoon go?
-=We only seek the truth of Science=-
- = Episode 12 =-
Doctor.
Go.
Doctor.
How long have you been sitting here?
You don't look well.
I told you to leave.
I'm not leaving.
Director Jung Byung Do...I didn't really understand why he worried so much about you until now.
He was afraid you would be like this.
You're just pretending to be strong and fearless.
What's wrong with you?
Please just leave now.
If you're not leaving, I'll leave.
Doctor.
Doctor!
Doctor.
Doctor!
I want to ask a question.
Before Director Jung died, you visited him..
and talked to him right?
I found this.
You know very well who owns this, right?
I've been looking for it for quite a while.
Did you two meet before he died?
Right, I did visit him.
Why?
What did you talk about?
If you are a forensic doctor,
committing suicide is very difficult.
Because you understand the pain...
your suicide will cause to people you leave behind.
The director left without leaving any message.
Why he killed himself...
I really can't understand it.
What did you say to Director Jung?
Why did he want to commit suicide?
Please, answer me.
Why did you want to meet Director Jung Byung Do on that day?
I have already told you.
Sometimes, there are secrets that can't be revealed.
There are no such secrets.
What happened 20 years ago?
I'm going to look into it.
Why did Director Jung want to commit suicide?
I have to find out.
Has Han Tae Joo's autopsy been done?
No, not yet.
Jung Woo Jin, it's me.
Sunbae, are you all right?
I'll do Han Tae Joo's autopsy.
Sunbae..
I'll do it.
Transfer the corpse here.
Please.
Doctor.
No!
You mustn't.
Doctor, you told me...
You must not be confused by your feelings when carrying out an autopsy
You must not examine Han Tae Joo now.
Director Jung...for me...
He didn't leave an explanation.
Why did he go like that?
How can I accept the truth of his death,
when I don't know the reason?
I feel like I'm going crazy.
Doctor.
You, do it with me.
Work with me.
Be the assistant and make sure my judgment is objective.
He was examined a while ago, but there was nothing unusual.
Then, he went so suddenly...
Before Director Jang Il Tae died,
did he speak of anything unusual?
No, just the usual daily matters.
His day at work, his thoughts of living abroad...
These are your husband's coworkers.
Did you know them?
Of course.
They had dinner with us every Sunday.
Eh? What do you mean?
Doctor, shouldn't you rest for a while?
You don't look too good.
Deceased, Han Tae Joo.
Height, 169 cm.
Weight, 49 kg.
Starting autopsy.
What's the conclusion?
Heart, liver, lungs,
all healthy.
Some gastrointestinal inflammation.
Cause of death, unexplained acute myocardial infarction.
Because she was pregnant, heart rhythm failure is also a possibility.
She was pregnant?
She said it was an early stage.
She did seem very uncomfortable.
Also, she said she was able to bear the pain for her child.
If...
the cause (of death) was not from her pregnancy...
What?
Of the victims,
only Han Tae Joo was pregnant.
Then what if Han Tae Joo did not die because of her pregnancy,
but of something else.
Before confirming, is there a recording of her death?
This is the CCTV recording from the elevator.
Doctor, do you think the same as me?
Caused from poisoning.
Don't you think so, too?
We cannot conclude that.
Vomiting and shortness of breath are common symptoms of poisoning.
Stop it.
Goo Young Hoon, Jang Il Tae, Kim Gyu Chul, Han Tae Joo.
These four people died suddenly.
The probability of poisoning is high.
So you want to say Director Jung falsified the autopsy reports?
You want to say that my father was murdered?
I'm not talking about what happened 20 years ago.
I mean the strange deaths at HanYoung Group.
Autopsies must be fair and objective.
Personal feelings must be disregarded.
This is what you told me.
Senior, I know this is painful.
But four people have died strangely.
It might turn out to be six people.
I found this photo at Jang Il Tae's house.
The dead Goo Young Hoon, Jang Il Tae, Kim Gyu Chul, Han Tae Joo.
Members of a mountaineering club.
All good friends.
Of the people here, four have died already.
Do you really think this is a coincidence?
Very likely, it's nerve poison.
Neurotoxin?
Thinking about the cases,
The victims were first poisoned somewhere else.
After some time, returning to normal daily life, they died suddenly.
Goo Young Hoon lost consciousness while driving a car.
Jang Il Tae was found in a restaurant's washroom.
Probably, he went there to vomit.
Kim Gyu Chul became short of breath,
and went to the roof for fresh air.
When he got there, he lost consciousness and fell.
There are some differences,
But nerve poison is the most probable cause.
Nerve poison...
Remember the Shinjuku gas incident in Tokyo? Sarin gas released in the subway...
Snakes and poisonous mushrooms contain goose paste toxin (amatoxin). -= sarin : A kind of poison gas used in wartime which may cause neural paralysis =-
Shellfish also contain toxin. -= sarin : A kind of poison gas used in wartime which may cause neural paralysis =-
Shellfish also contain toxin.
Botulinum toxin used in Botox injections causes botulism, and it is also a well known biological weapon.
The pufferfish's body contains the neurotoxin tetrodotoxin.
TTX is a nerve poison, also known as a neurotoxin, which has been found in a variety of species.
Go Da Kyung.
Tell Dr. Hong Sook Joo to check Han Tae Joon's blood and internal organ samples.
She is the most experienced in this field.
I understand.
You must also check the autopsy material from the three earlier victims...
to see whether there is any evidence of poisoning.
Okay.
An autopsy normally shows little evidence of death by poisoning.
A reliable quantity of the poison perhaps can be obtained...
only if the criminal confesses or there is a witness.
Identifying the poison is crucial.
Where are you going?
What is the status of the two other people in the photo?
This person is from HanYoung Group's research institute, Lee Cheol Eon.
This person is from HanYoung Group's planning institute, Bae Song Jin.
Lee Cheol Eon is working at the research institute.
Bae Song Jin is on a business trip and should come back tomorrow.
I will make a subpoena for Lee Cheol Eon for interrogation.
You are responsible for Bae Song Jin, Detective Choi.
I'll let you know as soon as NFS have the results.
I read the report of the interview.
I'm sorry; I did not mean to embarrass you, sir.
Even though Yoon Ji Hoon is my junior, he goes around deliberately creating trouble.
And I was dismissed because of him. It's not right.
But the contents of that interview...
That... That is...
I saw the autopsy report on your desk once.
I wasn't intentionally looking.
How much do you know?
The deceased, Yoon Young Jin, was Yoon Ji Hoon's father.
Director Jung Byung Do said that you falsified the autopsy report...
You really thought that that was true?
Answer me!
No! It is absolutely impossible.
Later, no matter who is asking... that's what you must answer.
I understand.
Although you didn't ask to be reinstated, you must promptly return to the National Forensic Service.
Shouldn't you stick to your training?
That's right.
But, if this matter arises once more...
It won't, absolutely. I guarantee it.
I get it. You can go.
Sorry to bother you.
What is the matter?
Are you Park Hee Cheong's father?
She worked at HanYoung Group for 20 years ago before passing away.
Why would you look into it now? 20 years have passed.
Even if somebody killed my daughter,
the statute of limitations is 15 years.
So what use is it?
Don't you want to know why your daughter died?
I've heard enough. Please go back.
Actually, my father died 20 years ago, too.
so I really want to understand what happened.
My father was cremated.
The other deceased were probably cremated, too.
A corpse is needed for the research that I want to do.
Was your daughter also cremated?
Hee Cheong is buried at the Silin Cemetery.
By buried, do you mean that her corpse is at that cemetery?
But then they dug it up for cremation.
Just when we were worrying about the monthly tomb management fee,
I received a phone call from the company.
They said they would pay the expenses.
Company?
The company's director telephoned and apologized personally.
Said that the company is not treating its employees well.
Director?
Former President Jeong Min Gi's son, Jeong Cha Young, the Representative Director.
Director Jeong Cha Yeong?
You should know why I had you come here, right?
I don't.
Deaths are occurring at HanYoung Group, one after the other.
You should have something to say about that.
I don't understand what you are talking about.
One after the other.
The mountaineering club's members are dying, one after the other.
If you know something about this, please tell me.
So that we will not see more victims.
No, I know nothing about this.
What is your business?
I'm a Police Officer. I would like to see Mr. Bae Song Jin.
Mr. Bae went to headquarters.
Headquarters?
Yes; if you leave your name, I will pass it on to him.
Why did he go to headquarters?
He has an appointment with Director Jeong Cha Yeong.
Mr. Lee Cheol Eon, you don't seem to understand the seriousness of the situation.
Four people have died strangely.
The killer is a cold-blooded animal that did not even spare the pregnant Han Tae Joo.
It might be your turn next, Mr. Lee.
Pregnant... Researcher Han Tae Joo?
That's right.
We are trying to prevent the next tragedy from happening.
We have evidence of Director Jeong Cha Yeong accepting illegal donations and property.
Were you all members of the mountaineering club?
Five years ago, when we were all assigned to a special project,
I accidentally discovered it when i opened the wrong computer file.
So...
I should have reported it then...
You were threatened by Representative Director Jeong Cha Yeong?
If the facts had been made public,
he would have been forced to give up his management rights.
So, he gave you money?
Yes, several times.
Not just once?
After the last time, the current total is 10 billion won.
After that,
the mountaineers started dying, one after the other.
Therefore...
The evidence of the illegal donations...
I have it.
So then...
Give me 2 billion won,
and that's it.
I'll hand over the disc with the evidence.
Can you guarantee that this is the last time?
Yes, I guarantee it.
What is it?
This person seems to have a very urgent matter.
Who is it?
He wouldn't say his name, but he said you would be interested in his question.
What did you say?
He was curious as to whether globefish toxin or goose paste toxin was used?
Let him come in.
Yes.
Please enter.
I will deal with the matter. You may leave.
Yes.
Who are you, and where do you come from?
From our country's National Forensic Service, I am Yoon Ji Hoon.
You do interesting work.
Please sit down.
Looks like poisons interest you very much.
They probably interest you, too.
Was it the same poison used..
20 years ago?
You...
are more interesting than I imagined.
20 years ago, it was easy to obtain poisons.
Either it was globefish toxin or goose paste toxin.
Which was it?
You seem to know a lot about poisons,
So-called scholars like you...
There are also things you don't understand.
Have you ever given poison..
..to a living person before?
After considering the person's physique, food habits and pre-existing diseases,
What is the..
..right drug then?
Not being able to do live experiments..
..is the blind spot..
of your so-called forensic science.
You killed people just because you wanted to know that?
Why?
Looks like I have your interest.
I performed an experiment just a moment ago.
Aren't you curious about the result?
The time is drawing near.
Have a look, quickly.
It hasn't been that long since he left.

Doctor!
Did the blood sample results come out?
No.
- Another one has died. - What?
Bae Song Jin died. Bae Song Jin from the photo!
There is one more victim; we must stop this.
Dr. Hong Sook Joo.
Yeah.
Did the blood sample result come out?
I was just about to call you.
Globefish toxin, bacillus botulismus, goose paste toxin, shellfish toxin...
The toxins and sodium have been tested.
The neurotoxins you mentioned did not show up.
Do not leave out a single one.
These books definitely list the poison that was used.
Five people have died already.
Why was the search warrant denied?
The evidence is complete.
This guy is a murderer!
Did catching the US soldier make you so defiant?
Sir!
Did someone see Jeong Cha Yeong kill people?
We're dealing with Jeong Cha Yeong here.
The big boss of one of the top 50 company.
If you want to touch him, the evidence has to be conclusive--not anything less.
Organic compounds - how about it?
No, the first basic inspection would have identified it.
Eliminated.
Antimony: Antimony is a chemical element ("Sb," from stibium), and many of its compounds are toxic. Clinically, antimony poisoning and arsenic poisoning are very similar, and a small amount causes headaches, dizziness, and depression.
Haven't you gotten off work?
Are you interested in the poison, antimony?
Oh yeah, Doctor, that...
I read that Mozart died of antimony poisoning.
That really whetted my curiosity.
I wanted to read more about it.
But no example of death by antimony poisoning has been recorded in our country.
Yes... yes... although it is a rare heavy metal,
there's no harm in noting it down.
Don't waste your time.
Better focus your thoughts on your thesis.
Why?
If you're going to do something, do it well.
Must read everything and study diligently, isn't that what you always say?
Listen to me. Alright?
Yeah.
Is this Dr. Yoon Ji Hoon?
Who are you?
This is Park Hee Cheong's father.
Are you really confident?
What do you mean?
I did not protect my daughter's final moments.
Nobody believed me.
What do you mean?
We did not cremate her.
The company told us to cremate her,
but we just pretended to do so and buried her somewhere else.
You mean that her corpse still exists?
Where is it?
Yes, I know.
We can probably find the evidence.
Can her body really help you...
find out how my daughter died?
I cannot guarantee it, but we will do our best.
Sir, you might want to wait in the car...
We'll tell you when we have finished.
Let's lift it.
How can this be?
A corpse, buried underground for more than 20 years...
How can it not have putrefied?
Doctor, where are you going?
What do we do with this?
- = Han Tae Joo sample =-
Did you know?
20 years ago,
it took the lives of five people.
Quite recently,
it has, once more, taken the lives of 5 people.
A silent criminal -
Antimony.
Antimony is a heavy metal,
and quite rare.
Moreover,
it has never been involved in a murder case.
And almost never been examined.
Nobody has realized how very suitable it is - as a lethal weapon.
Moreover,
In a case of chronic poisoning...
it can delay a corpse from putrefying (decomposing).
You already knew all that?
Now, tell me about 20 years ago,
Exactly what happened.
The thyroid cartilage bone looks to be fractured. -= Thyroid Cartilage: The slightly protruding cartilage at the middle of the throat =-
For sure this is an intentional death by hanging. -= Thyroid Cartilage: The slightly protruding cartilage in the middle of the throat =-
For sure this is an intentional death by hanging. -= Thyroid Cartilage: The slightly protruding cartilage at the middle of the throat =-
Don't be so sure about it.
The marks are all the same.
Strangle marks. -= strangle marks: rope marks visible on the body =-
It looks too clean.
Although this is also very common,
When the police moved the body,
it is possible to cause fractures of the thyroid cartilage.
From the photos taken at the crime scene,
this is a typical complete constriction death.
In such a complete constriction death situation,
because the carotid artery is blocked,
there should not be any excessive bleeding.
But from this aspect the victim...
Dr. Kang!
Chi Hyun!
Come to your senses, Chi Hyun!
Chi Hyun!
Chi Hyun, wake up! Chi Hyun!
Chi Hyun!
How did this happen?
Chi Hyun!
Dr. Kang!
His heart rate is slowing.
Chi Hyun!
Dr. Kang!
Chi Hyun!
- Dr. Kang! - Chi Hyun!
It's being recorded as the result of overwork, an endogenous cause of death.
His family members will get the corresponding compensation.
Dr. Lee Myung Han.
Cheer up and drink a cup.
What...
...did we run this far for?
Dr. Kang Chi Hyun...
...not us...
He didn't work himself to death to get compensatory payments for his family.
Every day, he stayed up late...
so that the corpses wouldn't pile up...
he carried on doing autopsies.
You once said that the living will lie.
But the dead will tell the truth.
Now...
What is the truth that the dead Dr. Kang Chi Hyun is telling us?
Dr. Lee Myung Han.
This...
Senior, you said that...
this was the future of forensic medicine!
We perservered at NFS...
because we believed you.
Senior, you...
have demonstrated faith to me,
but you have not demonstrated prestige.
I will leave here.
I must go to the US.
Truly,
what forensic medicine's true future is...
I will show you when I come back.
When I come back to the National Forensic Service.
Director Jung Byung Do,
worked as chief like this.
The National Forensic Service is a complex entity.
Three of us withstood the difficulties.
Taking on all these matters alone...
is definitely impossible.
Director Jung Byung Do...
Started to face a difficult choice.
Give up on the dream of a first rate National Forensic Service in light of personnel and funding shortages...
or...
start anew with force and spirit.
At that time, the corpse that entered the autopsy room..
was your father.
Why did your father die?
Do you want to know?
Your father, along with those who died with him,
died because they wanted to expose..
the evil doings of the old president.
The old president who was in danger used antimony,
and one by one,
he poisoned them all.
Just like the current president.
Antimony...
itself is a very rare metal.
Although the probability of being found out was very small,
the old President wanted to make sure.
So, he asked Director Jung Byung Do
to falsify the autopsy results.
Think of it as a price.
A huge, politically-machinated government grant appeared,
raising NFS's autopsy resources to a new level.
That was the deal.
Thus, the groundwork of NFS's autopsy resources was laid.
Do you know what it was?
It was...
Power.
Stop it.
I do not want to hear it.
If...
Director Jeong Cha Yeong's crime is exposed,
what also will be exposed, is...
where he obtained the antimony.
Jeong Cha Yeong...
obtained the antimony from his own father, the old President.
That is also where he learned how to administer it.
If Jeong Cha Yeong's crime is exposed,
the secret from 20 years ago...
will also be made public.
Then,
the reputation of Director Jung Byung Do,
known as the champion of forensic medicine,
as well as the prestige of the National Forensic Service,
will be utterly destroyed.
Your choice.
Your decision.
The prestige of Director Jung Byung Do,
the reputation of Director Jung Byung Do,
the prestige of the National Forensic Service,
isn't truth more important than these?
Reputation is not more important than truth.
I will expose all this.
What's with the long faces so early in the morning?
That is... President...
In the office...
Found it.
You...
What is this?
This office...do you have any idea where you are?
Yes, we have.
This is the office of Jeong Cha Yeong, director of HanYoung Group.
Jeong Cha Yeong,
I arrest you on suspicion of having killed, by poison, Goo Young Hoon and four other people.
Very happy to see you once more.
HanYoung Group's director Jeong Cha Yeong was arrested this morning.
He is suspected of poisoning five employees of HanYoung Group.
Jeong Cha Yeong will be indicted next week for the poisoning of five employees.
But taking into account the wishes of the public,
...a Citizen's Committee hearing will be held.
The committee will decide whether to hand it over to the prosecutor.
Citizens Committee meeting?
Antimony was found in Jeong Cha Yeong's office.
It was also found in the victims' blood samples.
The prosecution evidence is quite conclusive.
But where did he get the antimony?
This has not been investigated,
but we will do so as soon as possible.
Then, it is possible that a third party will be arrested.
Jeong Cha Yeong might have been framed.
Prosecutor Jung, when investigating something related to a big company,
be very careful, always.
If the public participates in the inquiry held by the Citizens Committee,
It will make the investigative process even more transparent.
- = Autopsy Testimonial =-
Doctor, did you hear?
Tomorrow, the Citizens Committee will hold a hearing.
I was the main examiner in Kim Gyu Chul's autopsy,
so I will be called as a witness.
Since you were the main examiner for Han Tae Joo,
you will be called, too.
You said what you wanted. Leave.
If you need me, please call me. I'll be in my room.
- = Citizens Committee Chairman =-
- = Citizens Committee Members =-
Are you going to present yourself to the Citizens Committee?
Yes.
Is something the matter?
This is this morning's mail.
I thought that you should have a look.
You came?
Yes.
Didn't Senior Yoon Ji Hoon come with you?
He said that he was going to come here. Has he not come yet?
You came.
We shall now start the 33rd meeting of the Citizens Committee.
Today's case is...
whether murder suspect Jeong Cha Yeong...
should be prosecuted or not.
Have you seen Dr. Yoon Ji Hoon?
Maybe he mailed this letter before his death. - = Jung Byung Do =-
.
Ji Hoon...
When you see this letter,
I may have already left this world.
20 years ago,
when I first saw you,
that was my life's most precious day.
It was also the most nightmarish day.
That day,
was the day of my first falsified autopsy.
Although it's a weak rebuttal,
But I am unable to give up the National Forensic Service.
Don't be anxious.
You're just learning.
Yes.
Grasp the scalpel.
I know, but my hand...
Start to dissect.
The 20 years together with you...
have been the happiest time of my life.
Thank you for accompanying me during the last part of my life.
Also, the fact that I made such a bad decision,
I hope you can understand.
I consider honor more important than anything.
And also.
-=We pursue only the truth in science=-
I can't stand to see myself losing everything... -=We pursue only the truth in science=-
I can't stand to see myself losing everything...
because of one mistake.
During our years together, I've tried to conceal my secret.
But now, this is the only way I can do that...
and not deceive you.
I hope you can understand.
I am sorry.
Also...
I will love you forever.
Did you perform the autopsy of the deceased Kim Gyu Chul?
I did.
What was the conclusion of your examination?
The heart, lungs, liver, and stomach...
of the deceased Kim Gyu Chul...
did not exhibit any unusual symptoms.
The blood sample results...can you explain?
They showed 108 micrograms of antimony.
Then, did Kim Gyu Chul...
truly die from antimony poisoning?
Yes, he did.
The conclusion was death by antimony poisoning.
Thank you.
Witness, you can step down.
Chairman,
I present another witness.
From our country's National Forensic Service,
Examiner Yoon Ji Hoon.
Permission granted.
Witness, concerning the victim of February 9,
Han Tae Joo.. You performed the autopsy, didn't you?
Yes.
Did you find antimony.....
in Han Tae Joo's blood?
Yes.
There were 126 micrograms of antimony.
End of examination.
However...
Inspecting Han Tae Joo's body,
126 micrograms of antimony...
was possibly not a lethal dose.
This.. what do you mean?
With regard to an in vivo lethal dose of antimony,
we do not have enough data to conclude...
that 126 micrograms of antimony is a lethal dose.
In other words, we can't conclude that this dose caused Han Tae Joo's death.
What is the meaning of this?
Are you saying that Han Tae Joo did not die from antimony poisoning?
My autopsy conclusion is...
that Han Tae Joo's cause of death was...
not poisoning by antimony,
but acute internal causes.
That type of death is...
a natural death.
