(Characters and incidents used in this drama are fictitious.)
Seal her hands and feet,
and transfer her to the NFS.
Wait, excuse me.
I don't think you should untie the knot carelessly.
Sorry?
- Who are you? - He's...
Prosecutor Do Ji Han. He just transferred to the Eastern District.
Prosecutor Do, I took the photos.
If we don't untie them, it's hard for us to transfer the body.
- Won't that destroy the evidence? - Then why don't you move the body?
Just as it is. All the way to the bottom of the mountain.
Gosh, you're really bad-tempered.
I got it. Sure, let's untie the knots.
But film the process of untying the knots, and keep it for evidence.
Okay?
- Record the video. - Yes, sir.
What is it? Did you find something?
- She doesn't have any fingerprints. - What?
This is Prosecutor Do Ji Han from Seoul Eastern District speaking.
I guess you do know that you were transferred to the eastern district.
- Who is this? - It's Chief Prosecutor No Han Sin.
Aren't you coming in today?
My gosh, hello, sir.
A body was found on a hill. I went to the crime scene first.
- I'll go after the autopsy. - Deputy Chief Prosecutor Do.
It's your first day. Shouldn't you visit the Prosecutor General first?
The field is the most important place for prosecutors to visit.
I'll visit him later when I have time. He'll understand, right?
- Bye. - What do you mean he'll understand?
What? He already hung up on me?
All right. Let's see.
What's up with his nose?
All right. She's a Jane Doe.
A hiker discovered the body and called it in this morning.
As you can see, we found her stuff, but not her ID.
Her fingerprints are all destroyed, so we're running her DNA.
Current time, 10:51am.
I'll begin the autopsy.
- Anemic condition. - "Anemic condition".
(It refers to the anemic condition after the blood is drained out.)
Teeth marks on the left side of her neck.
"Teeth marks on the left side of her neck".
(Teeth marks: marks caused by bites)
- Let's copy the marks. - Yes, sir.
Stab wound on the left side of the collarbone.
"Stab wound on the left side of the collarbone".
(A wound caused by stabbing)
- The depth is 15.7cm. - "The depth is 15.7cm."
- The length is 3.4cm. - "The length is 3.4cm."
- The width is 0.7cm. - "The width is 0.7cm."
This is odd.
- The wound shape looks strange. - Make sure you take photos.
Both arms have ligature marks.
Bleeding during the incident.
The fingertips were carved out. The fingerprints are destroyed.
"The fingertips were carved out. The fingerprints are destroyed."
Do you think the killer did so to conceal her identity?
Yes, if not, the killer wouldn't have gone this far.
She was skinned in various parts of her body. Abrasions.
"She was skinned in various parts of her body. Abrasions."
Vulva has been torn and bled.
Traces of sexual assault.
"Vulva has been torn and bled. Traces of sexual assault."
Then are you saying that she was raped too?
We think so.
- Swab the inside of her vagina. - Yes, sir.
The subclavian artery was cut. The heart was punctured.
Her heart was stabbed too, right?
At one go.
I found food in her stomach. It wasn't digested yet.
Does that mean she was murdered right after her meal?
Before she was murdered, her body was extremely stressed.
In that case, the digestive system stops working.
The cause of death. Cut subclavian artery and punctured heart.
The knife that went through this wound stabbed her heart.
We believe she passed away due to excessive bleeding.
She looked pale.
There were no bloodstains in the burial site.
It means that the killer drained out all the blood before burying her.
And the teeth marks are very clear.
- Is there a reason for that? - It's a postmortem mark.
The murderer bit the corpse?
If the murderer bit her this hard,
she would have resisted. Then the teeth marks can't be clear.
You said she was raped earlier.
Then we must have his DNA. He's done for.
We'll know once we get the sperm test.
You know the knot that was used to tie her hands and feet?
We'll write a separate report on that.
Hold on.
Wait a second. It went like this and that.
- Mr. Yang. - Yes.
Let me see.
I can't stand being curious.
I looked it up online on my way here.
It's a handcuff knot that was used to imprison people.
I found out that it was used in the military.
And one more thing.
If it pierced the heart through the subclavian artery at once,
doesn't that mean he's a pro?
Well, that may be true.
Even when you stab someone accidentally with a cutlet knife,
there are times when you rupture the heart in one go.
But it means that he knew the location of the artery...
- and the distance to the heart. - Exactly.
Was it last month?
A woman stabbed a man who almost raped her with a fruit knife.
She stabbed the same location.
But she was a kindergarten teacher, wasn't she?
There are cases like this.
Gosh, he's something else. He is indeed.
- "Something else"? - I meant that you were awesome.
Awesome. I'm sure the autopsy doctor has it right.
Excuse me. He's not an autopsy doctor. He's a medical examiner.
Oh, right.
We have to use that title now. I'm forgetful. My apologies.
By the way, the jerk who killed that woman...
He's not a first-timer.
The sperm test was a negative.
- What? - What?
He didn't even leave his DNA.
See? I'm telling you. That scum is a pro.
And we have the identity of the victim.
Luckily, her mother's DNA was kept in the missing person's database.
We should really check on that.
Where is Hye Bin? Where is her?
We just finished the autopsy.
I can't believe this.
My poor daughter, Hye Bin.
(Kim Jung Ran, Seong Hye Bin's mother)
- Gosh, please calm down. - Goodness. You'll fall.
Please take a seat.
Gosh.
Ma'am, I understand how difficult this must be for you.
Since when did she go missing?
She went missing two days ago.
She left for her part-time job,
but she never came back home.
Deputy Chief Prosecutor Do Ji Han.
You went for a hike on your first day. You're like an old lady.
I worked in the narcotics unit for five years.
I can't help myself but check the crime scenes.
Can I take the Wuseong-dong hill murder case...
as my first case in the Eastern District Prosecutor's Office?
Why? Did you get attached to it because it's where you first went?
But Prosecutor Eun was already assigned to that case.
- It means she worked in vain. - It's a rape-murder case.
The victim is young enough to be her younger sister.
It'll be too hard on her. I mean, people have emotions.
No, I can conduct an objective investigation.
- To this day, I... - I saw how...
you couldn't even look at her body,
then you cried in front of the victim's family.
Are you sure you can be objective?
I think it'll be too tough.
She had a stab on the right shoulder blade, about 15.7cm deep...
and 3.4cm long.
Teeth marks on the left side of the neck.
Abrasion on her arms and legs. Bleeding from 14 places.
Cause of death, severed artery due to the stab on her shoulder blade...
and heart failure.
She lost all of her blood right after death,
giving her the anemic condition.
Then they tied her hands and feet to abandon her body easily...
and buried her in secret by digging up...
a rectangular-shaped hole with a depth of 1m...
and 80cm in length and breadth.
I can conduct an objective investigation.
Prosecutor Eun has a great memory.
Doesn't she sound useful?
What was that? I never knew we had another talent here.
The more I find out about this place, the more I like it.
Prosecutor Eun.
Go over the initial investigation with Gangdong Police Station...
and report it to me later, please. No. Report it to me later.
Yes.
This isn't just any old knife.
I have the first analysis of Seong Hye Bin's drug test.
I didn't find anything.
It looks like she doesn't even take cold medicine.
She's just a normal girl.
- Okay. - Autopsy documents for tomorrow.
Will you read them beforehand?
Leave them here.
Are you leaving right on the hour? Are you sick?
- Do you want me to do overtime? - I'll see you tomorrow. Goodbye.
Let's go get some meat.
This is similar.
(Death of a woman in her 20s in Wuseong-dong)
(Seong Hye Bin, job seeker)
Give me that. Over there.
Okay.
Let's see.
Is this the first time you two met?
- Yes. - Say hi to each other.
This is Deputy Yang Soo Dong.
He gets angry when you call him Deputy Yang...
because that sounds like a chicken coop.
If his last name was Yuk, he would've been a kind of soup.
Deputy kind of rhymes with jeopardy too.
We're in a meeting to catch a murderer.
How can you two sit there and joke around?
Goodness.
My gosh.
Oh, hello.
I am Cheon Mi Ho, and I work with Prosecutor Eun Sol.
I look forward to working with you.
Look forward to what?
We can all just do our jobs.
- You're right. - What?
He's harsh.
- Hello. - It's all right with me,
so let's just keep all of the old desks and furniture.
Don't get them changed.
It takes up time and money. What a waste, right?
- Yes. - Right.
- Are we all here? - Yes.
Let's greet each other later and go right into the case.
Sure.
Name, Seong Hye Bin.
Age, 20. She was a job seeker.
She went MIA after she left work at around 5pm...
at the convenience store two days before her body was found.
Did you find anything on the scene?
We found her wallet and belongings...
in the bag that was found next to her body.
But something was odd.
We found her credit card and cash in her wallet,
but only her ID card was missing.
They left money and took her ID card?
They were trying to trick us and stop us from identifying her.
It's so obvious.
- I know that. - All right, now.
The walk back home from the convenience store is...
a pretty deserted alleyway, so there is no security camera.
It's difficult to locate her whereabouts on that day.
So you have no leads?
I heard the first thing...
that detectives look for nowadays are security cameras and DNA.
It's not that. The cameras are...
Stop making an excuse.
We used to have no problems investigating without those things.
You have to get out there.
Do you all investigate sitting around at your desks?
That's the problem.
Right, I can do it without the security footage.
Deputy Yang, yes.
We don't run out blindly to investigate anymore.
Come on, everyone.
All right, let's do this, okay?
Mr. Yang, please find what I asked for in the morning.
- Yes. - What? What is it?
We're not at the stage to tell you yet.
It's just an assumption. I'll tell you in time.
Okay. Let's get to work.
Can you bring the documents to me?
Can you wait one second, Mr. Yang?
- Mr. Yang. - Whatever.
(National Forensic Service)
The evidence for Seong Hye Bin's case.
One second.
That's where her ID card would have been in.
Your thumbprint gets left behind...
as you take this out, right?
There are many thumbprints.
A lot of people touch your credit card.
Then can you make samples of each one of them except for hers?
Prosecutor Do.
- I brought it. - Give it to her.
- What is that? - Evidence.
What?
That looks pretty old.
- How long has this been? - 30 years.
That's a long time.
You'll see a part of a thumbprint on the buckle.
Please compare that with the thumbprints...
found on her credit card.
Prosecutor Do, what are you doing?
I don't know.
How should I put it? My sixth sense?
Let's talk when we have the result.
Your sixth sense?
- 6th sense? - 6th sense?
Sixth sense?
(Material, blade length, total length, blade thickness)
Doctor Baek.
We have the analysis result of Seong's case.
Okay.
There he is.
Hello.
There were a total of eight thumbprints on the card.
One of them is a match with the thumbprint...
- found on the buckle. - What?
So the thumbprints on a 30-year-old evidence...
and today's are identical?
- Yes. - What's going on?
I told you. This wasn't their first murder.
Then which case is that belt from?
Wuseong Serial Murder case.
- What? - What?
Wuseong...
A total of 10 victims.
The serial murder that broke out around Wuseong-dong area...
between 1984 to 1988, for over 5 years.
You all know, right? It's 1 of the 3 most famous cold cases.
Don't you feel your blood boil?
Right, Prosecutor Eun?
This is a historical moment.
Then are you saying Seong Hye Bin's murderer is...
the murderer of Wuseong Serial Murder?
But I thought people said that he already died.
He killed 10 people in 5 years.
He couldn't have suppressed his will to kill.
Come on, that's not right.
He was a young man 30 years ago. Why would he suddenly die?
What do you think?
We can't jump to a conclusion because the thumbprints matched.
- Mr. Yang. - Yes.
- All right. Take a look. - What is this?
Tied the knots the same way, killed the same way,
buried them the same way,
and the teeth marks after their death.
The patterns are exactly the same.
The thumbprint is the cherry on the top and the smoking gun.
The murderer of Wuseong Serial Murder...
who's gone off the grid for 30 years after May of 1988 is...
now on the move again.
Could he be a copycat?
Like you said, this was a high-profile case.
Everyone knows what the murderer's routine is.
Would they copy his thumbprint too?
They're both partial, so we can't say for sure.
Okay. That's enough.
That's why I want to prove this through our investigation.
Then good luck with your investigation.
Let's go.
Okay.
What?
I believe we should begin the investigation...
by leaving the possibility that it could have been done...
by a copycat or by someone who held a grudge against her.
Prosecutor Eun, you are objective. Let's do that.
But let me tell you one thing.
Criminals always make mistakes.
Those mistakes are opportunities for us, okay?
The serial from 30 years ago.
We just opened the Pandora's box.
Kang Hyun speaking.
Hello?
I'm Baek Ho Chul.
You have something to tell me, don't you?
I heard you were at the hospital.
I'd been looking for Han So Hee for a long time.
How long were you going to hide her?
You must think I'm despicable.
I know very well.
This tragedy...
was of my own making.
I thought that Beom would give everything up for So Hee.
I was afraid.
I beg of you.
It was Beom's lifelong dream to study in the US.
But now he wants to stay because of you.
Is that what you want?
Can't you give up on him for me?
Okay.
I'll do that.
I never imagined that she was carrying...
Beom's child at the time.
Had I known, I wouldn't have done what I did.
You're mistaken.
That baby was my brother's.
It can't be.
After it was miscarried,
I ran a DNA test.
- It was Beom's child. - But...
How...
I'm getting married.
You'll be an uncle soon.
I caused this disaster out of greed and ambition for my son.
So Hee...
has been in a vegetative state for over 10 years.
I will carry the burden until I die.
So please,
I beg of you as a father who has a son,
though I don't deserve to.
Please leave both So Hee...
and Beom alone as they are.
Why are there so many of them? What's going on?
They're called hyenas for a reason.
They took the bait called Wuseong Serial Murder.
The criminal will be watching TV, right?
He'll be anxious to know that we're onto him.
Right?
Hello, everyone.
Are you investigating the Wuseong Serial Murder?
Could you give a comment?
There's the prosecutor in charge. Sir?
- That must be him. - Over there.
Any comments?
Give us some details.
- They flocked over. - Oh dear.
Look at that.
- Any comments? - Talk to us.
- Fill us in. - How are things going?
What a mess.
Prosecutor Eun, it's a total disaster.
It got out of hand.
Reporters are saying the Wuseong killer woke up.
I don't know how and when they caught on.
"Wuseong killer" is the most-searched phrase...
on the main search engines.
On a mountain in Gangdong-gu Wuseong-dong,
the body of a woman in her 20s was found stabbed and buried.
The police are investigating.
The woman lost touch with her family after leaving...
her part-time job at a convenience store in Wuseong-dong.
She was reported missing.
Police noticed her fingerprints were badly damaged...
and that her wrists and ankles were tied using an unusual knot.
They believe the MO is similar to the Wuseong...
serial killings that happened between 1984 to 1988.
(The Fearsome Serial Killer Awakes)
You scored huge. The whole country's in uproar.
I tend to create big issues.
My nickname was...
The Rabid Dog, the Doberman.
Rumors spread already?
A Doberman never lets go once it bites.
I'll catch him.
I don't think we should exclude a copycat killer.
Fine. Just catch the killer.
The Prosecutor General ordered we and the police set up...
an Wuseong task force team.
We'll send over...
the medical examiner who autopsied the victim.
That would be Dr. Baek.
I'll still show up to work here.
They won't let me do anything there. I don't like it.
Can he work on such a huge case on his own?
It's a serial.
As his superior, I should represent...
I heard that the task force team already invited another examiner.
- Who? - Someone the President appointed.
The chair is here.
Hello, I'm Prosecutor Do Ji Han.
Hello.
How are you?
It's been a while. Let's sit.
I'm Pyo Yoo Seong and I was asked to lead the team.
You all know this is an important case...
which the public is following closely.
Let's all work together and solve it.
- Sure. - Okay.
You played a huge role in catching serial killer Yoo Han Cheol.
You're the only person who can lead us on this case.
Will the NFS be joining us?
Yes, of course they will.
I invited only the best from each field.
I hope you'll back me up.
Sure.
Shall we begin?
The Wuseong Serial Murders.
From 1984 to 1988,
over five years in the Wuseong-dong area,
10 women were raped and murdered.
The investigation lasted 13 years,
and over 200,000 people were involved.
Over 17,000 people were considered suspects,
but they failed to catch the culprit,
and it became a cold case.
That's right. All the victims were killed,
and with no witnesses, the investigation made no headway.
But Lee Kyung Ja, the last target,
managed to get free...
and give us the criminal's profile.
The killer is about 180cm tall,
wears 260mm-sized shoes and is very strong.
He's very agile and is in his 20s.
But after his last victim got away,
the criminal went dormant.
That's the composite drawn based on Lee Kyung Ja's description.
This would be him 30 years later.
It's what we expect him to look like in his 50s.
The MO, the way he killed, is slightly different.
The location of the stab wounds and the method of disposal.
Serial killers evolve.
Anyone, when repeating a task,
is bound to find a way to do something quicker and easier.
Serial killer Yoo Han Cheol...
had a routine that involved cutting up his victims.
At first, the cutting job was very haphazard.
Later on, as he became experienced,
he got good enough to cut at the joints.
He said something after we caught him.
"Chopping up bodies was so hard,"
"so I bought and studied an anatomy book."
That's right. He did research.
Look at the fingers. How he cut off the fingerprints.
He's not an ordinary guy.
Okay then.
First.
He makes sure the bodies are found late.
Second.
He makes sure to delay the victim's identification as long as possible.
That's the Wuseong killer's routine.
In the beginning, he left the body at the crime scene.
After the third murder,
he hid them in agricultural waterways or mountains.
From the fifth, he started to bury them.
Did you find anything during the autopsy?
He used a unique weapon.
I'm trying to identify...
Did he use the same weapon 30 years ago?
- It's possible but not confirmed. - That's fine.
On this victim's body or at the burial site,
did you find the criminal's DNA?
No, we didn't.
Isn't extracting DNA the most important of the NFS' duties?
If the killer insists on using a unique weapon,
that too can be a clue.
So are you telling me that we should catch a serial killer with a knife?
Pardon?
