(Characters and incidents used in this drama are fictitious.)
Name, Yeom Sang Goo, age 76.
The front of right calf, multiple skin abrasions.
Burn marks. Possible ligature marks.
Homicide, natural death. We can't exclude either.
This rat ingested poison. Blowfish poison.
Kim Hyo Jin, as per Article 250 Clause 2 of the Penal Code,
you're under arrest for the parricide of Yeom Sang Goo.
Here's the analysis report of tetrodotoxin in Yeom Sang Goo.
(Toxic Substance Report)
- So what? - That's not the cause of death.
He didn't take a lethal dose.
What?
You guys found tetrodotoxin, but he didn't take a lethal dose?
The toxic substance report just came out.
Traces of toxic substances take long by nature.
Traces?
Traces of poison can kill rats, but not people.
Then how do you explain Yeom Sang Goo's death?
If it wasn't the tetrodotoxin, why did he die?
I don't know yet. I haven't found what caused the external injuries.
External injuries?
Oh, the skin abrasions on his calf and burn marks on the knees?
Should I tell you what you told me before?
Those injuries aren't enough to kill a man.
In February of 2018, middle-aged men got into a fight on the street.
An angry man punched the other guy in the face.
Just one punch.
But the guy who was punched died in his sleep at home.
The cause of death, heart attack due to ischaemic heart diseases.
But he didn't die of an illness.
The deceased had a heart disease, and the punch affected his heart.
Are you lying to me again?
No, take a look.
Look. It's a true story.
("A Punch Kills a Man with a Heart Disease")
When a patient has an acute heart disease,
a punch is enough to trigger the heart attack.
That's why we call it the catalysis, not the cause of death.
(A minor pressure that can worsen a condition)
But not all heart diseases are caused by these minor pressures.
Bruises on your arms and legs go away within a few days,
but not the heart. When the heart is bruised, you die.
That's why we must find it out. Okay?
You're here.
We should release Kim Hyo Jin, right?
We can't prove her motive, and she's irrelevant to the cause of death.
Okay. Let's release her.
And we'll go back to square one and start the investigation again.
Unidentified burn marks.
Doctor, these are the materials for tomorrow's autopsies.
Every contact leaves a trace.
Yes, of course.
There's a trace, but what was in contact?
Sorry? What contact?
- Get ready. We're leaving. - Pardon? Go where?
You already saw the crime scene. We already took all the evidence.
It's been three weeks since the gas got cut off.
Get the dryers,
iron, and any products that might heat up in the house.
The oldest son, Yeom Dae Chul, got married 13 years ago.
He has a son who's in middle school.
His business went under five years ago. He works at a company now.
His only apartment was auctioned off when he couldn't pay the mortgage.
And the second oldest, Yeom Ji Sook.
After she got a divorce, she runs a clothing stall in Dongdaemun.
She's behind rent and used up all of her deposit,
so she's about to get kicked out.
What about Yeom Sang Goo's assets? Did he leave an inheritance?
His only asset was the house he resided in.
After the redevelopment plan was approved, the value multiplied.
I heard that last year, there was quite a scene in that neighborhood.
To sum up, with the insurance money and the property,
they could have gotten 600,000 to 700,000 dollars when he died.
Something is very fishy about the family.
The fact that they were financially struggling,
and they caused a big scene to change the cause of death.
In the initial questioning, both Yeom Dae Sik and Kim Hyo Jin lied.
We cannot believe their statements.
I'll ask questions about Yeom Dae Chul, Yeom Ji Sook,
and their acquaintances.
Didn't the father live in a collective housing area?
Most of the residents are retired senior citizens, right?
They wouldn't open up to strangers.
Then should I give it a try?
- No, I... - Hello, ma'am. Hi.
Why don't you have a drink each?
Gosh. Thank you.
My pleasure. You're friends of Uncle Sang Goo, right?
- Yes. - Who are you?
- Do you know Mr. Yeom? - I'm his niece.
I'm from Anseong.
I came to visit him since it's been a while.
Gosh, may I sit down?
I mean, Uncle Sang Goo...
isn't the type who would leave that easily.
When it comes to age, there's no set order of departure.
Gosh, he had the worse luck when it came to children.
What do you mean? He had three children.
What good are they?
They never showed up once.
- Hey, you got all the points. - You got all the points.
- You got the points. Keep going? - Pardon?
- Yes, go. Keep going. - Keep going? Okay.
Then I guess his children didn't take care of him.
His son came to visit not so long ago.
Which one? The oldest?
I live in the house behind his.
It looked like he was taking Mr. Yeom to a nice place by car.
Do you remember when that was?
Goodness, how could I remember that?
The days are all the same for me now.
- You got them. You got the points! - Goodness.
- Goodness. - This is your third time.
- You're right. I got the points. - Gosh.
- Every point costs 1 cent, right? - Yes, 1 cent.
You don't have enough cards, light cards, and red ribbon cards.
- And I have the trio. - It's your third time.
Then it comes out to 134 dollars and 84 cents.
- Goodness. - Oh, my. What's all this?
- You're in big trouble. - Gosh. Goodness.
All that matters is that we all had fun.
Then why don't I just forget about the score?
Gosh, it's so hot. This is stuffy.
It's been ages since I played. My fingers feel so stiff.
Hi, Prosecutor Eun.
The oldest son, Yeom Dae Chul, visited Yeom Sang Goo.
The whole family is a pro.
We keep finding new things about them.
This isn't a merely dysfunctional family.
It's a family full of hidden agendas.
Please look into Yeom Dae Chul's recent card statement.
We must find out the time of his secret visit to Yeom Sang Goo.
(Opening of 24-Hour Specialized Center for Dementia)
This is it.
This is the place.
On June 17, the day before Yeom Sang Goo's death,
Yeom Dae Chul swiped and canceled a bill for 780 dollars.
Specialized center for dementia? He said he didn't know about that.
Let's go to the administration and check.
Let's go inside.
Patient Yeom Sang Goo?
He was to get tested for dementia on June 17 at 10am,
but he didn't get tested.
What? Why is that?
That day, Mr. Yeom disappeared from the parking lot.
Can we look at the surveillance camera from that day?
- Please look here. - Okay.
June 17... June 17. You said it was in the morning, right?
Yes.
Here. Here he is.
The guardian came alone and checked in.
Then he said he'd bring his father.
Then did he go missing right after that moment?
I'm not exactly sure.
Look at that.
Wait, isn't that Yeom Ji Sook?
You're right.
We've been after Yeom Dae Chul.
Why is she suddenly popping into the picture?
When did this car leave?
After the old man went missing,
his guardian came back and took the car to go find him.
The son and daughter who weren't in touch with him for five years...
suddenly came to see him.
And he passed away the day after.
I'm sure something was going on.
I need to find out the whereabouts of...
both Yeom Dae Chul and Yeom Ji Sook on this day.
Cell phones automatically connect...
to base stations even if you are not on a call.
If we analyze the data of base stations with their phones,
we will be able to find out their whereabouts.
All right.
That way.
May I ask you something?
Have you seen this guy on the morning of Sunday, June 17?
I don't know.
Can you take a closer look?
I don't know.
Can you at least take a look? See if you can remember.
Goodness.
Work must be tough. She's angry.
- Let's go. - Let's leave.
- Hello. - Hello.
Hello, we're from Seoul Eastern District Prosecutor's Office.
It's about the morning of June 17.
A woman in her 30s and a man in his 70s were here, right?
When is that?
The old man had dementia,
so he must have been here with his daughter.
Dementia?
Oh, could it be them?
Do you remember anything?
They were sitting on that table over there.
They only ordered a glass of juice...
and left about 10 minutes after if I remember correctly.
This is 130 Songpadae-ro.
So this is the 130.
What kept him so busy after he lost his father?
Why did he stay here for an hour?
Dong Sik, wake up. We have to go.
Leave me alone for an hour.
You want to sleep for an hour? He stayed here for an hour.
We have to go. Come on out.
What? Darn it.
Hey, don't be so tough with us.
We know that Yeom Dae Chul was here.
We need the information for our investigation.
According to Article 26 of the Attorney-at-Law Act,
I cannot disclose any confidential information about my client.
My gosh. You are so awful.
("Taking Care of the Elderly with Dementia")
- One second. - What is it?
("Q and A of Adult Guardian System of the Elderly with Dementia")
My grandfather has been a bit funny lately.
I'll come back to discuss it with you.
Let's go.
(Police Patrol Division)
Yeom Ji Sook.
Yeom Ji Sook? Oh, here she is.
She brought an old man who was lost.
What?
- She brought her dad here? - What?
That old man was her father.
Wait, that can't be right.
She said she brought him because he seemed mentally unstable.
She made sure that I promised to take him back home.
- Goodness. - That's odd.
- Prosecutor Eun. - What's going on?
Mr. Kang, Mr. Cha. What brings you two here?
This is where Yeom Dae Chul's last signal was found.
Why are you two here?
Yeom Ji Sook left her dad here.
One came to leave him here, and the other took him.
They put on a huge show with their dad.
Did Yeom Dae Chul take his dad then go home?
Yes, that's what shows on his cell phone trace.
What about Yeom Ji Sook?
She left him here, then went somewhere again.
Ms. Yeom came to change...
the beneficiary of Mr. Yeom Sang Goo's insurance.
She said Mr. Yeom wanted to change the beneficiary.
She brought the documents,
but it was missing a few things, so it never got cleared.
It was requested by Mr. Yeom?
Yes.
We should have the paper with his thumbprint.
Right here.
(Application to Change the Beneficiary)
(Signed by Yeom Sang Goo)
I'll take this.
Do you know any good pork skin places?
Pork skin? I can never have enough of that.
Let's go.
What?
(Sigang Pork Skin)
This is a famous place. It's got the best pork skin.
Did you ask them not to cut it?
Of course. I'll cut it myself.
Yes!
We aren't going to eat it.
What?
Put it in here.
(Evidence)
How much is this?
Darn it.
My gosh.
(National Forensic Service)
This is different. Another one.
What are you doing?
I thought I smelled some meat burning. That smells.
Then get out.
Oh, my gosh. Is this new Korean barbeque?
It looks weird, but it tastes great.
What are you doing?
We're looking for the weapon that burned Yeom Sang Goo.
Do you have to try this to know?
Pork skin doesn't do the trick. Show me your skin.
Goodness, what's wrong with you?
That's enough.
- Get out if you won't help. - Me?
You're responsible if the fire alarm goes off. Okay?
Let's go.
What did you two do...
on June 17?
That's the day before your dad passed away.
I worked. I worked overtime too.
I was working at my shop too.
And then?
You met with your dad.
You both told me the same lie.
That you haven't seen your dad for the last five years.
Goodness. I am so sorry.
I was at the hospital...
with my dad on the 17th.
Which hospital?
It was a hospital for dementia patients.
You already knew that he had dementia?
I stepped up because neither of you seemed to care.
I couldn't just leave him like that.
I wanted him to get treated.
It's not that.
(Adult Guardian Application)
You tried to buy a house by applying to become his guardian.
You had a meeting...
with a family law attorney on that afternoon.
You wanted to take his house?
You're unbelievable.
Oh, the thing is...
Someone...
had to become his guardian anyway.
The house was about to be put up for an auction,
and I had no money on me.
I just wanted to make a living.
(Day before Yeom Sang Goo's death, June 17, 9:25am)
Dad, it's me. Dae Chul. Come with me.
I have no money. No money.
Okay. I understand.
Dad, isn't it frustrating to be stuck in here?
I'll let you go.
I really shouldn't have done it.
But all I did was take him to the hospital. That's the truth.
I was really dumbfounded when he went missing that day.
You weren't the only one...
who went to the hospital that day.
- What? - What?
You tried to change the beneficiary...
of Mr. Yeom's life insurance to you.
(Application to Change the Beneficiary)
(Signed by Yeom Sang Goo)
What's she talking about?
This thumbprint. Yeom Sang Goo didn't do it himself, did he?
What are you talking about?
You took him from the hospital and made him do it.
What? You abducted Dad?
You left him alone in the car.
I went inside for a while to register.
I took him for a while...
to get his thumbprint.
Then you left him at a patrol station?
Even if he had dementia,
was it easy to leave him alone like that?
He was your father.
I was afraid my brothers would find out.
I went to his place at first.
But...
(Day before Yeom's death, June 17, 9:35am)
Hang on.
What's he doing?
Dae Chul was taking him somewhere.
Something looked off.
Dad, it's me, Ji Sook.
Ji Sook, your favorite. Come along, Dad.
Come with me.
Get out.
You see, our dad...
loved me the most.
After our mom died,
I paid all the insurance premiums.
Isn't it just right that I get what I paid for?
Is that why you went on and on about the insurance?
At least I didn't try to take the only thing that belonged to Dad.
What? Are you done?
Will you stop it?
The thing is,
I couldn't change the beneficiary's name.
I don't know what all this fuss is about.
Ma'am, I wasn't able to set myself up as the legal guardian.
What did I do wrong?
Ji Sook.
You struggled with your dad while forcing him to put his print.
Here's the footage from the cafe's security camera...
and dashboard camera footage from a car outside the hospital.
I sent them to the NFS for analysis.
- Thanks. - Sure.
Here, have a look.
Dad, do you see these two marks here and here?
Put your thumbprints here.
No.
Dad. Will you help me out?
I'm hungry.
Will you just help me? I'm really struggling.
No.
Relax your arm.
I said no.
I'm really struggling.
Here, Dad.
Do you call that a physical struggle?
Dae Chul, have a look at this.
Dad. Dad? Get out.
No.
Come with me.
I don't want to go.
Dad.
I was just trying to take him to see a doctor.
His cause of death was myocardial infarction.
It can start with a small shock...
that results in death after a period of time.
The physical struggles with you were enough to cause his death.
- What? - What do you mean?
I'm saying that both of you...
are responsible for your father's death.
Gosh, not me.
You struggled with him to get his thumbprint.
What? You hit Dad first.
- You murderer. - What? How dare you?
Watch your language or I'll just...
- You brat. - Fine, hit me. Hit me.
- You killed Dad! - What are you doing?
What's wrong? You did it!
You're the one who took him!
No matches.
Dr. Baek.
Yeom Sang Goo's autopsy report. The director wants it now.
Tell him I got it.
The insurance company sent a letter.
- They want cause of death. - COD, myocardial infarction.
And type of death?
Do you want to do the autopsy and write the report?
You're ready to do so.
Yeom Sang Goo...
Did you analyze the camera footage we sent?
It's neither. Neither of them are involved in his death.
Neither of them?
He'd be bruised if there were any serious physical altercations.
That isn't enough to set off the heart.
The old man was tied to a door all day.
There were no outside causes that could've triggered anything.
If these aren't it, where could he have sustained such trauma?
I'm looking for that with pig skin.
Did he really say it's neither of them?
Then is it really over?
- Hello. - Hello, sir.
I just took out a life insurance policy.
- Pardon? - What?
I don't want my kids to fight and end up...
in prison when I die.
Prosecutor Eun.
- Guess what a natural death is. - Pardon?
Dying naturally of an illness within yourself...
and not an outside cause or trauma.
In Korea, about 300,000 people die each year.
Over 90 percent of them are natural deaths.
Most people grow old and die.
Did working with the NFS make you think every death is a conspiracy?
And old man who died of a myocardial infarction.
What other reason is there to an old heart that stopped beating?
Who wants to find out?
Stop wasting time, and close the case.
(Pork Skin Restaurant)
Can I have some soju?
What is this?
I don't usually drink soju, but I crave some today.
Thank you.
Is this pork skin? I've never had it before.
What? Are you not going to eat it?
It's for testing.
Stay and have some. I put it on the grill.
- I have no time. - It's a waste.
You look hungry too.
Sit back down.
And old man died,
and we have no killer.
Every death has a cause. Don't write a novel.
I shouldn't.
But aren't you here because you don't have an answer?
You look troubled.
You say, "Don't write a novel," then give crucial information.
You have something, don't you?
Did you give me something to keep?
You hate unknowns more than anything.
(Unknown: Unknown cause of death)
Right knee, burn marks.
It might mean something.
- Take close photos. - Okay.
The burn marks from the autopsy.
Can we share information, please? Seriously.
Look, the meat is burning.
Hang on.
This is that.
I saw this before.
(July 9, 2001)
Gosh.
What is it? Are you sick? Or did you get hurt?
Yes, I fell.
Let me see.
How did this happen?
(Cloudy, the temperature is 24°C, higher than yesterday.)
I think I got it. I figured it out.
- Figured out what? - Hold on a second.
Yes, it's me.
Get me the surveillance footage from Yeom Sang Goo's area...
on the day of his death.
There was a sudden shower at 3pm that day.
Yes, footage before and after 3pm.
