(locations, and incidents in this drama are fictitious.)
(It was filmed in accordance with COVID-19 prevention guidelines.)
Whatever the case, more heinous criminals will show up.
This team is always working very hard.
But there still has to be someone preparing for what may happen.
I need you to take up a case.
A married couple was murdered in their home two weeks ago.
There was cash lying around, but he didn't even touch it.
They think it's an act of resentment masked as a burglary.
It's clean.
It means the victims were overpowered...
without any sort of resistance.
(Gungok-dong Family Murder Case, September 24, 2003)
A type of systematic crime committed according to a plan.
Is this a way of expressing...
the culprit's emotions caused by a grudge they hold?
They are both hiking shoes.
This one is from Suseong-dong, Gangnam.
And this one is from Gungok-dong, Jongno.
They are from different districts, but it's the same culprit?
(Jinjung-dong, Gangnam-gu)
There was another case in Jinjung-dong.
You're not an investigator. Why are you here?
Please. I must check the crime scene.
Hey. Didn't you hear me? I told you to get lost, you punk!
Darn it.
This is important.
The victim was hit by a blunt instrument.
And the safe wasn't touched either.
This is the third murder, and his only purpose is...
to kill.
It's a serial murder.
(Hwanghwa-dong, Jongno-gu)
Hurry to the scene in Hwanghwa-dong.
A senior citizen was murdered.
Why did he suddenly start a fire?
He tried doing something he had never done before.
I'm sure he came across an unexpected situation.
He either wanted to destroy traces he didn't want anyone to see.
Or it could've been his trace.
I mean the CCTV footage.
We got a shot of the back of the culprit.
Let's put out an APB.
You want us to do that with just the footage that shows his back?
Are you suggesting that we give him a warning...
- that he could get caught? - That's correct.
The only way to stop him from striking again...
is this.
The footage shows a man walking. He's wearing a black jacket.
The police have identified this man in the footage...
Even after you let out the APB...
At least share the information with me!
It's been over three months...
and the police still don't have a single lead on the culprit.
The decision for an open search.
Is this the police's lifeline?
Or is this the beginning of doom?
Did he give up on committing another crime to hide?
Or is he still planning another crime?
You never miss a day.
We never know when the crimes will start again.
We will catch him. Certainly.
What if the culprit changed the MO?
What do we do then?
- Gosh, what are the police doing? - Right.
They still haven't been able to catch a punk like this.
- I know right? - Yes.

Inspector Song.
Last week, I made a wish while looking at the first full moon...
of the year.
What?
You see, it's been four years since I joined the team.
I really hope you can start...
talking to me casually this year.
Hey, you're too much. It's been four years.
Woo Ju says it's his wish.
Woo Ju, our universe! Can't you just grant his wish?
Was that a joke?
I'll start talking casually from now on.
Really?
Gosh. Had I known it'd be this easy, I would've brought it up long ago.
Had I known it'd be this easy, I would've done it long ago.
I took too long, didn't I?
Are you playing favorites?
You never laugh when I tell jokes.
That wasn't funny at all, but you laughed.
He laughed because he likes me, not because I'm funny.
That's right.
Hey, what's with you guys this morning?
You're so mean.
Anything showing a similar pattern?
- No, nothing with the same pattern. - Let's see.
(Daily Case Report)
An assault case...
Nothing.
I hope he has stopped.
(Thursday, February 12)
Whatever he may be doing,
let's just stay focused and keep going.
We got this.
(Profiling Report)
Why are you going through the profiling report?
Hoping to find some clues.
Clues, my foot.
Because we listened to that idiot, Song Ha Young,
the entire police force was criticized for being incompetent.
And now, the culprit has gone into hiding.
Where are you going?
Why do you care?
Oh, it's a record.
He got here less than 30 minutes ago.
(Hwanghwa-dong Murder)
(Victim Yoon Jung Yoon, Age 65, Female)
The clock's ticking, but we have no idea...
where this scum is.
- Oh, you're early. - Hello.
- You're early too. - How have you been?
Woo Ju, say hello before you step out.
Nice to meet you.
This case made me feel the need to study,
so I'll be joining you today.
Good thinking.
- I'll be right back. - Okay, hurry.
We'll get started when Woo Ju is back.
- Take a seat. - You can sit here.
Professors.
There are so many scumbags in this world...
that we've got lots of studying to do.
About the serial murders of affluent senior citizens.
You haven't identified the murder weapon yet, have you?
No, not yet.
What causes that triangle-shaped scar?
We've been checking every blunt weapon we can think of,
but haven't found a match so far.
The abrasion, hypodermal bleeding, and laceration.
Also considering the depth of the dent,
it's not a light weapon.
Considering the weight and force applied,
a steel hammer would be a match,
but they're usually either round or sharp.
And the handle is long, so it'll be a hassle to carry it around.
Captain Kook, I'm beginning to think that your guess may be correct.
It makes me feel uneasy.
That the culprit made the weapon himself?
If it really is the case, we won't be able to identify it.
I've never seen anyone put so much effort into murders.
- Let's go. - Gosh, it's so cold.
Anyway, is the lady in that building okay?
- I think so. - My goodness.
- What if she died... - That building.
- Gosh. - My goodness.
What happened in that building?
Last night, a lady on the second floor nearly died.
Thank goodness she didn't die.
A stranger followed her and stabbed her. My gosh.
She didn't die?
She's still alive?
Richard Chase was also abused by his parents as a kid.
He experienced bed-wetting,
committed arson, and animal abuse,
which are common characteristics of serial killers.
He killed adults and children...
in a brutal manner.
He didn't have hostile relationships with the victims.
Why did he brutally murder victims chosen at random?
Most murderers like him kill for pleasure.
For pleasure, not because of anger?
That is the most frightening part.
It means killing makes them happy.
Killing satisfies them,
so they can't stop.
They actually become bolder, looking for bigger pleasures.
- Correct. - That's why he mutilated...
and even cannibalized his victims.
Sexually deviant killers tend to commit such acts.
So Richard Chase's cases are often categorized as lust murders...
and as sexual homicides.
Sexual homicides?
That's right.
The way he mutilated his victims doesn't show a specific pattern.
There's no pattern at all.
He didn't know much about human anatomy,
nor did he try to study.
Right, and he didn't even bother tidying up the scene.
He didn't even try to conceal evidence.
So we could say that Chase's murders were unsystematic.
He chose his victims at random, and it wasn't premeditated.
And even when he was caught at the scene,
he was very confused.
On top of that, he suffered from schizophrenia.
His cases were typical unsystematic murders.
We need a list of your psychiatric patients...
from the past 5 years, dating back to 1999.
Don't you feel all cooped up being stuck in the press room?
You're still doing field coverage and writing all the articles.
I commend you for your enthusiasm, but your juniors will hate you.
Aren't we both used to people hating us?
Don't you worry.
Not me.
What are you talking about? Your juniors hate you way more.
So?
Are you going to do it for me or not?
We have to catch the serial killer.
You know that the Special Crime Squad is busy.
Come on. Don't be like this.
Of course, Mr. Kwak knows how busy you are.
He keeps filing a report every time his girls go missing,
but the police don't seem to care,
so he's getting all anxious.
Good grief.
Hey, over here!
He's here.
This is the detective. Say hello.
Reporter Im told me a lot about you.
Hello, Chief Kim.
I'm Kwak Man Hyun.
(Mr. Kwak in Mapo, Girls in their 20s)
You didn't have to introduce him to me.
Come on. You two should meet.
- No pressure. - Yes.
In any case, pretend not to know me when you run into me at police HQ.
I always do. Are you worried I'd suddenly say hi to you?
Who knows?
The one thing I learned while working as a detective...
is that you should never trust anyone.
- What brings you by? - Hello, sir.
This is my first time back here after the team was formed,
and this office still looks crummy.
Hey, do you have water?
- Water? - Forget it.
Shouldn't you at least be able to tell...
whether it's a killer's hideout...
or a place for catching killers?
Why are you already trying to pick a fight?
Hey, those red marks. What are they about?
Today is the 154th day after the 1st case broke out.
And the 105th day after we put out the APB on him.
Do you guys even remember your families' birthdays?
If you're going to tell us to drop it, just leave.
Must you kick me out already?
Why else would the chief of the Special Crime Squad be here?
Goodness. Are you a psychic or what?
A scary wolf is roaming around inside the rabbit burrow.
We won't stop until we catch the wolf. End of discussion.
Goodness. Okay, I heard you.
Just be careful and stay out of Bong Sik...
and Captain Yoon's sight.
You're the chief of the Special Crime Squad.
Why do you always walk on eggshells around them?
What? Do you not walk on eggshells around your juniors?
A little bit.
Captain Yoon is one thing,
but Bong Sik has such a nasty temper.
I do too.
What do you say? Should I go ahead and load my gun?
That lunatic will actually pull the trigger. That's the problem.
He's been on everyone's case with that temper of his.
Still, we can't just sit back and do nothing.
We don't know when the culprit will kill again.
It's not like I don't know that! Goodness.
My head hurts.
I'm leaving. This place is giving me a headache again.
Would you like a cup of tea...
Why couldn't you ask sooner?
Why are you getting mad at that perfectly nice kid?
Goodness, taking your teammate's side?
Be good. I'm watching you.
Goodbye.
So why were you really here?
I came because I missed you. Happy?
Goodbye.
I'm sure you were here to nag me!

Hello.
Yoon Tae Gu of Seoul Metropolitan Police Agency.
- I heard you had information. - Yes, I called.
(Nokdangwon)
I think it's that guy.
Hey!
What are you doing?
What's with you?
We're detectives of Seoul Metropolitan Police Agency.
Is that so?
- I'm sorry. - Okay, fine.
Darn it.
The train is approaching.
Please step behind the safety line.
Do you think we live with pointless anxiety?
It's a habit that comes with the career.

- Gosh, it's pouring. - It's cold.
- Hello. - Hello.
- Are you two coming in? - Yes.
- Are you going out? - To the marketplace.
Look what you've got there.
(Korean Beef Gopchang)
This is really good.
- Anyway. - Yes?
"Is this the police's lifeline or is this the beginning of doom?"
That article was really harsh.
Why? It's true. What about it?
Inspector Song won't show it,
but he is already in a tight spot after he let out the APB.
Yes, so who on earth is this Inspector Song?
One of the two people I respect the most.
On Behavioral Analysis Team? The profilers?
Yes.
After I heard something from Inspector song on my first day,
I never once regretted...
volunteering to join the Behavioral Analysis Team.
What did he say?
He asked me that day for the reason why I volunteered.
Nothing really came to my mind,
so I immaturely replied, "Because it seemed cool."
He said this to me after a while.
Do you know the story of the blind man and a lantern?
Someone asked a blind man...
who was walking down a dark road with a lantern in his hand.
You can't see anyway. Why do you carry that around?
Why do you think so?
He wanted others to see clearly and not fall down while walking.
I see. That's cool. A lantern.
(Victim's profile: Han Seok Hoon, Yang Kyung Hee)
(Kwon Hyun Sook, 54, Female Many impacts on the head)
Then tell me his name too.
- Inspector Song Ha Young. - Song Ha Young?
- Honey. - Hey, honey.
- Did I keep you waiting? - I just got off.
- It's raining a lot. - Yes.
- Can you put it in here? - Okay, sure.
- Yes, okay. Thank you. - Sure.
- Enjoy. - Goodbye.
My gosh, why is it raining so much?
I'm home.
Mom?
The receiver cannot be reached.
I'm sorry. I'm late.
Why didn't you pick up your phone?
I left it at the bakery.
When I went back, they were already closed.
You didn't have to get this.
And from now on, tell me to get these.
No.
I'm much better than you at picking out food ingredients.
Goodness, I'm glad I made the soup earlier.
Honey, you should also celebrate Ha Young's birthday with us.
The sky is blue, and cherry blossoms are in full blossom.
The weather continues to stay nice and makes us feel warm.
The temperature will rise tomorrow,
and it'll be a bit hotter in the south like early summer.
But the air is a bit drier.
In Chungcheong and Gangwon Provinces...
- What's that? - Daily case report.
I said we won't return to the office...
after visiting the prison,
and Woo Ju gave these to me.
Where did we find such treasure like that kid?
I think I still have the luck to be with good people.
Am I included in that luck?
Why? Do you think you aren't?
You're worried over nothing.
- Nothing, right? - No.
No, but I'm not sure if that's good or finding something is good.
I wouldn't feel so frustrated only if we could figure out...
if he stopped or changed his MO.
A residential district, in public, stabbed in the right side,
serious injury inflicted by the stab.
Camping knife?
- Camping knife? - Yes.
Why?
May I see that again?
- Which one? Sinheung 4-dong? - Yes.
This is just an assault case.
- May I see it? - Which one? Right here?
"April 15, 3:30 a.m."
"A residential district, in public, victim, female."
"Serious injury inflicted by the stab on the right side."
- "Weapon, camping knife." - Camping knife.
Camping knife.
(Attacked with a camping knife.)
Could you please make a call to Woo Ju?
Sure. One second.
Hey, Woo Ju.
Can you look up "camping knife" and find some reports?
- Camping knife? - Yes, this year.
I remember seeing it.
One second.
You should begin with Dongjak Police Station.
(Dongjak Police Station 1st quarter, 2004, Daily Case Report)
(Camping knife)
Two cases popped up.
Two cases?
Yes. In Sinheung 2-dong and Sinheung 5-dong.
And both cases took place in February this year.
Tell me about the victims.
Both of them were women in their 20s.
And they have serious injuries.
Both were categorized as assault cases.
Print the case reports.
Let's go.
(Conference Room)
Captain Yoon.
Did you look into it?
The cases in Guo-dong and Borim-dong took place...
in January and February.
Captain Yoon. Do you think the culprit is the same guy?
Both victims had serious injuries.
And they were reported as assault cases.
So both victims can't remember his face, right?
They only remember seeing his back when he was running away.
Both victims said that he was short and had a small build.
But it might be a bit of a leap to say that they were attacked...
by the same guy.
But the wealthy senior citizens who were murdered...
lived in different districts.
But even if we assume that his MO changed,
it's still confusing because the victims didn't die.
Both victims were...
stabbed in the abdomen by a camping knife.
The same weapon and location of the stab wounds.
Based on these factors,
we can deduce that the culprit might be the same guy.
But I'm not sure if that's enough to report this...
as criminal intelligence.
This part bothers me the most.
A 170cm-tall suspect with a small build.
The description is similar to the guy we're looking for.
This is from Geumcheon Police Station?
Yes. I went to school with the detective in charge.
And we recently had drinks.
When he was telling me about the case, something was off.
So we looked into this ourselves.
What about this?
At our last meeting, Inspector Song...
mentioned the possibility that he might change his MO.
I remembered what he said that day.
So we kept an eye out to see if there were any cases,
following a specific pattern.
So these cases...
could have been executed by him? Did I get that right?
Whether it's true or not,
it still bothers me.
But this isn't a homicide.
We don't have any excuse to take over the cases.
They are just two assault cases.
Let us investigate this ourselves.
Goodness. It's all because of this jerk.
I'm starting to see everything as serial murder.
Whenever we get a case, I immediately think it might be him.
Same here.
But these cases don't seem to suit his style.
Whether it's the same guy or not, once there's a reasonable doubt,
we must investigate.
Even if it might be a waste of time,
that's better than losing him because we didn't try.
Woo Ju, you got the reports, right?
Are they important cases?
- We're not sure yet. - Is it him?
There's a small possibility if he changed his MO.
We'll be back. Let's go.
We'll be back.
(For people's safety and happiness)
Okay.
(We can find your lost items!)
The victim is in the hospital now.
She needs to rest. So you can't interview her.
- This is her statement. - Okay.
He kept following him, so she even threw her purse at him.
But he wasn't interested in that.
How did you confirm it was a camping knife?
Given the size of the stab wound,
we knew it wasn't a kitchen knife.
The victim also said that the knife was small.
It came up to about a half of our palms.
I showed her a few photos.
She said camping knives looked the closest.
- Was there an eyewitness? - Yes.
He heard screams, so he opened the window and yelled.
Then the culprit ran away.
He was short, skinny, and balding.
He was wearing a shabby tracksuit.
Can we meet with him?
Sure.
And what about the other two cases?
The other two cases?
Two cases with a similar MO took place in February.
Take a look here.
- Sinheung 5-dong. - Okay.
Sinheung 2-dong.
You need to ask the team in charge. I don't have information on them.
He's in charge. Detective Kim, come here.
He followed her to the door of her house.
He stabbed her when she had her key in the hole.
He sounded like a total nutcase.
Did he try to steal her wallet?
After stabbing her, he left without even touching her bag.
So the victim was about to go in.
And this jerk came at her all of a sudden.
He grabbed her arm and turned her around.
Then he stabbed her right away.
She couldn't remember his face as she was shocked.
She said he was short. Right.
He was about 170cm tall.
Not having surveillance cameras in a blind spot like this...
is always a problem.
But we have more cameras compared to last year.
This is an improvement.
Right. That's good.
- But we still need more. - Right.
- Is that the house? - Yes. The one on the second floor.
That's where I screamed.
Where was the culprit?
Over there. Under the street lamp.
Something seemed off, so I was watching them.
All of a sudden, the woman started screaming.
So I screamed, "Hey! What are you doing?"
When I screamed,
he ran away. And he was really fast.
You also said that he was short.
He was short.
He was losing hair. He had a bald spot on his head.
Didn't he wear hiking boots?
I'm not sure about that.
Right. You were pretty far.
What do you mean by he was fast?
The light was bright, so I could see him running away.
Enough for you to see that he was a fast runner?
Yes. I was surprised how fast he was.
The victim suspected it could've been an act of retaliation.
So we also thought that he knew the victim personally.
And we started questioning her friends.
So you didn't find any fingerprints or evidence for both cases?
Right. He followed her...
to her house as if he was determined to hurt her.
She wasn't sure if he was following her.
But he came into the building too.
And she looked when he took out something from his jacket.
And he stabbed her right away.
This case took place in Guo-dong.
But it's the same MO with Borim-dong.
Only the location changed. And no evidence either.
On top of that, it rained that night.
A camping knife, a stab wound in the abdomen,
and no valuables or money were taken.
She didn't know she was being followed because of the rain.
The victim was attacked and on the ground.
When he saw a car coming into the alley,
he was surprised and ran away.
The victims gave similar descriptions. But no luck yet?
He was short.
And when she was on the ground, she saw his feet running away.
He was wearing sneakers.
Not hiking boots?
She only said he wore sneakers.
Sneakers.
(Keep people safe, and enforce the law fairly.)
The fact that he didn't take money or valuables bothers me the most.
Right?
He committed crimes in January and February.
It's April, but he hadn't committed any crimes afterward.
Is this the cooling-off period the Analysis Team mentioned?
Let's check the scene first.
Is this the place?
Yes.
- This is way too bright. - Yes.
That's odd.
Three people had serious stab wounds from a camping knife...
after these attacks.
All of them took place late at night.
All of the victims were young women.
The only difference is...
one of them happened in an alley at a residential area.
And the other two, in front of the victims' houses.
They were attacked in different locations,
but having three cases with the same MO...
implies that there might be more cases.
And all of the victims were stabbed...
in their stomachs.
Do you think it's him?
I doubt it.
The weapon, MO, and time don't match at all.
But they seem to have a similar build.
Right. That's why we can't be certain.
But he said the culprit was a fast runner.
If he was visibly fast,
I don't think he could've done that in hiking boots.
Right. You can't run fast in hiking boots.
There's a photo of him from behind, and we know he wore hiking boots.
So he probably didn't wear them.
But the culprit we're looking for...
brutally murdered his victims with a blunt weapon,
not even giving the victims to resist.
Even if he wanted to change the MO, I don't think he would use...
such a small knife.
Let's say that it is him.
All of these assault cases would be attempted murder cases.
That wouldn't have satisfied him.
Then he wouldn't have used the same weapon three times.
Seeing how he repeated his crimes, can't we interpret that...
he didn't know if the victims were dead or not?
Even if you're right, that doesn't change anything.
He rarely left any evidence after breaking into the houses.
Someone like him followed his victims?
There could've been witnesses. He wouldn't take risks like that...
because he's super careful.
What if it's not him?
Since all the victims were injured,
we're not looking for a murderer, but a violent man who robs people.
No. He wasn't interested in valuables. He's not a robber.
What if our guess is right?
What if the victims were only injured...
because he couldn't finish the job?
Then...
we have two serial murderers in this country.
(Mr. Kwak in Mapo, Girls in their 20s)
This one didn't die either?
The same weapon was used in the three cases.
A camping knife?
Look, these three locations...
aren't far from each other.
The type of weapon, where the victims were attacked,
and even the time. These cases have a lot in common.
"Seriously injured..."
Why? We can't investigate them because they're not murders?
Is there something else?
Where are you going?
Captain Yoon, come here for a moment.
Guo-dong, Borim-dong.
These cases took place in January and February of this year.
We believe these were done by the culprit...
of the serial murders. We're investigating at the moment.
It's not the same guy.
What?
This is a different guy.
But the height and the build look similar.
But they have nothing else in common.
From the MO to the weapons, everything's different.
Didn't you say the MO could change?
Yes, it could change.
But he already got a taste of killing people with a blunt weapon.
There's no way he's now using a camping knife, which is smaller.
Then there's an even lesser chance that this is a serial case, right?
These victims didn't die.
Thankfully, the victims didn't die.
But it could actually make the culprit even more violent.
We must catch him...
before there's another victim.
What are you talking about?
This serial killer is already giving us a huge headache.
How will we track down a murder that hasn't even happened yet?
Let's draw a facial composite.
Yes, let's start with a facial composite.
All the victims are alive.
And we have a witness too, so it can be done.
The victims are still traumatized...
and don't remember his face.
Let's try forensic hypnosis.
He has a slim face.
(Use of hypnosis in the investigative process to find clues)
He has small, slanted eyes.
And...
Oh...
He looks like he's losing hair.
Where? At the hairline on the forehead?
Yes.
(National Forensic Service)
As you know, the killer isn't after money.
(Facial Composite)
If it's not about money or personal grudges,
there can be only one goal.
Killing.
(Facial Composite)
Yes, he looked like this.
He was skinny. He had a skinny face like this.
This is pretty accurate.
- Thank you. - No problem.
- Thank you. - No problem at all.
Let's go.
Oh, you're here.
Take a look at this.
We had the witness verify the accuracy of this composite.
Looks good, right?
So this scum may be the one who killed the senior citizens.
It's not the same guy.
No.
We'll continue to investigate keeping in mind the possibility...
that it could be the same guy.
Whether it's the same guy or not,
we're investigating the same case, aren't we?
- Yes, we are. - Very well.
- Let's go through it again. - Okay.
It took place late at night...
under a brightly lit street lamp.
The Borim-dong case also took place under a street lamp.
Normally, perpetrators...
look for dark spots to hide themselves.
And the victims were attacked from the front, not from behind.
Did he reveal his face on purpose?
- Hold on. Watch this. - Okay.
The victim...
was walking this way.
She suddenly felt that someone was following her.
She threw her purse, so he'd just take it and leave.
But he didn't care about the purse and kept following her,
so she started walking fast, terrified.
The culprit must've continued to follow her.
Then he suddenly swung his knife at her.
- Hold on. - He made her turn around.
But it could've happened the moment she happened to turn around.
The one thing these cases have in common is that...
the victims were stabbed in their abdomen.
They were all attacked from the front.
They all took place in the southwestern part of the city.
Could it be someone who lives in the area?
Why does the Special Crime Squad think that these cases...
were committed by the culprit who killed the rich senior citizens?
That scum targeted houses in the affluent neighborhoods...
of Gangnam and Gangbuk.
But as you can see on this map, this isn't a rich neighborhood.
Let's go through everything again.
Our theory is that he attacked the victims to kill them.
And these attacks took place five times in southwestern Seoul.
That could mean he didn't know that the victims didn't die.
Do you think his MO will change once he finds out they didn't die?
It's highly likely.
If he didn't know they didn't die,
and if that was why he kept using the same MO,
these "attacks"...
could turn into murders once he finds out.
In fact, that is what I'm most worried about.
Then how would he find out?
Through the news or the newspapers, probably.
Or he could visit the scenes again.
You said it rained when the attack took place.
Yes.
You can't see clearly when it's raining,
which makes things easier for the perpetrator.
On top of choosing a brightly lit spot,
he purposely revealed his face. Why?
This wasn't about a personal grudge, so why did he reveal his face?
Why? Why did he do that?
I really don't get it.
What time did the incident take place?
Around 9 p.m.
Let's go back to the scene in Borim-dong.
Yes, ma'am.
So we'll check this area every day from now on, right?
Yes.
Do you really think the culprit will return to the scene?
First, we have to put ourselves in his shoes.
Why did he choose these areas?
Did he look for easy spots where he can attack someone and run?
Or is he familiar with this area?
Gosh, this feels like a waste of time.
I feel like we're on a stakeout...
because of something that hasn't even happened yet.
No, we're not. We're trying to track down...
a serial killer who has already committed murders.
It is the same case, but remember that we're looking at it...
from a different perspective,
on the premise that it's the same guy.
(Pureumae Park, Dongjak-gu)
This morning at Seoul Pureumae Park...
a woman in her 20s was found stabbed to death.
The victim had been stabbed with a knife multiple times...
and had been bleeding a lot when she was found.
People were heartbroken to hear she passed away in the ambulance...
on the way to the hospital.
The crime occurred at a blind spot...
where no CCTVs were installed.
It's been a struggle to find traces of the culprit due to no witnesses.
The importance of having safety measures in parks...
has been raised with this incident.
Seoul City has announced that...
they will inspect the park's street lamps...
and install more CCTVs to remove blind spots.
(Map of Seoul Metropolitan City)
The Pureumae Case...
also occurred in the southern district of Seoul.
This happened at a park though, not a residential street.
On top of that, the weapon wasn't a camping knife but a kitchen knife.
You're seeing this as the same punk when it is this different?
Or is it a third suspect or something?
Come on, just hear him out.
Carry on.
Woman in her 20s with stab wounds in her stomach.
The time of the crime and area of attack...
match with the other victims.
Although it's a park...
it's a shortcut from the subway to the residential area...
so residents of this neighborhood used this route often.
Why does that matter?
I'm saying, it has to be considered as a residential street also.
We have a description of the suspect too.
Wait, there was a witness?
No.
The victim gave testimony...
while being transported into the ambulance.
I guess...
she was alive up until then.
It was a man in his 30s, about 170cm in height...
with little hair...
dressed in dark workout clothes.
In a phone call with her boyfriend right after the incident, she said,
"A stranger followed me and stabbed me with a knife."
The conversation ended with that.
Just as we feared...
the culprit wasn't satisfied with his last crime.
So our guess is that he committed another crime...
with a larger and sharper weapon.
- I still disagree. - With what?
I disagree with everything that the Analysis Team says.
Don't you think it's time we stop being swayed by them?
- Darn it. - Gosh, that temper of his.
Just let him be.
So then the Analysis Team thinks...
that the culprit of the Southwest Case and this one...
is the same guy, right?
Yes. If you take a look at the pictures from the scene...
it's neither sexual assault nor mugging.
It's a different guy from the serial murders of the rich elderly then?
Yes.
I don't want to say this...
but we have to catch...
two serial murderers.
Don't blow this matter up hastily.
If we announce there are two serial murderers...
without clear evidence...
the level of anxiety the people will feel will only multiply.
Their trust in the police will also waver.
Physical evidence found at the scene is not the only clue.
There are bound to be traces in the time and place he resided that day.
A trace that may seem trivial...
becomes an important clue to help find the culprit.
We can't only look at the weapon, but we must expand the conditions...
and look to see if there are any similar cases.
What are you saying then?
You want us to request cooperation...
from 36 police stations in Seoul?
I think if we can, we must do it.
(Special Crime Squad 1, Team 1)
- Is he serious? - Seriously?
We have so much to do.
- Gosh. - What a headache.
Seoul Metropolitan Police Agency and Special Crime Squad...
held a meeting with 31 chiefs of police...
to solve the serial attacks on women in the southwest of Seoul.
They established an information room for crimes with no motives...
and announced they'll be increasing cooperative investigations.
We are a personal bodyguard service.
A bodyguard just for myself.
We're starting our special event for these self-defense sprays.
Now offering a huge discount.
The reason is...
With violent crimes targeting women happening consecutively...
in the southwestern district of Seoul,
the level of anxiety has jumped amongst the people.
Within this year, there have been six cases of attacks in this area.
It's been revealed that one of these cases was a murder case...
causing huge shock in the community.
We'll connect to Reporter Kim Ju Young.
On the morning of the 16th at Pureumae Park,
a murder occurred.
Pureumae Park is looking empty...
due to no visitors coming by.
One citizen expressed her anxiety by saying...
"I'm scared to walk alone, so I'm refraining from going out."
The police have increased the amount of questioning...
and have been doing their best in trying to obtain evidence.
But it seems like they haven't seen much result.
(Looking for witnesses, 10,000-dollar reward)
("Please report if you saw the victim around 1:30 a.m. at this park.")
You're coming home way past midnight today too. You must be tired.
- Are you going to the morning mass? - Yes.
I'll drop you off.
Gosh, it's fine. I go there every week anyway.
It's bright outside already. Don't worry.
No, I'm going to drop you off. Come on out.
My goodness. I told you, it's fine.
Please think of your servant Michael...
who you called away from this world.
He participated in the saint's death through baptism.
So please let him enjoy his resurrection too.
Those who are sound asleep with the hopes of resurrection...
The devil has hid himself again.
Please think of them...
and let them meet your shining face.
(July 2004)
Why are they under construction every day?
They're going to build a house at this point.
The noise is killing me.
Police.
(Senior Inspector, Kook Young Soo)
I'm a police officer.
Yes, I'm a police officer.
"Spooky Thursdays," my gosh.
They've stopped night studies at girls' high schools.
I'm having nightmares every day...
because I'm worried this may end up a cold case.
I think the world is becoming strange.
Seriously.
I feel like I'm running in circles.
What does he want to nag about now?
Yes?
Where are you, Young Soo? Hurry up and come in.
Why?
I think we caught that punk.
"That punk?" Which punk?
That punk has a forged ID card.
Forged ID card? What are you talking about?
Don't tell me you're talking about the one I lost four years ago?
Gosh, just stop talking and hurry on over here!
The serial murderer of the wealthy senior citizens...
we caught that punk!
Turn the car around, Ha Young.
(Seoul Metropolitan Police Agency)
(Statement Recording Room)
There.
(Personal information)
You arrested him as a suspect of a sex worker's abduction?
Yes.
The women on the staff continuously couldn't be reached.
The pimp reported him after much suspicion.
He was arrested around 05:30 a.m. today.
He had his victim, Gu Young Chun's phone,
as well as articles from the lost women.
Mapo Police Station is done investigating them.
We're also in the process of searching through the car...
of the woman who went missing two days ago.
What about the missing victims?
"I killed them. I didn't."
"I buried them. I didn't."
His statement is everywhere.
Anyway, Chief Kim Bong Sik.
How did you come to catch him together?
The owner of the business, Kwak Man Hyun,
is an acquaintance of Chief Kim Bong Sik.
That's why he's not showing up?
Anyway, are you sure that guy said he did bad stuff...
to those elderly people?
Yes, I think so.
But he kept going off speaking nonsense on our way here.
What do you think, Inspector Song?
We should first check...
if he has a mental condition...
or a history of receiving personality disorder treatment.
Oh, the one you wrote down in the most recent profiling report?
Yes.
- Detective Nam. - Yes, sir.
- Run over and check. - Yes, sir.
You!
You're at Seoul Agency's Special Crime Squad.
So get your story straight!
Did you kill those ladies...
and buried them in secret too?
Yes.
What's this about killing the elderly?
What do you think?
I literally killed those old people.
How dare you smile?
Are you referring to the elderly you killed...
as the victims of the murder case of the wealthy senior citizens?
Detective!
Gu Young Chun is still under questioning, right?
I came all the way here from Mapo Police Station.
- Can you share something? - I have nothing to share.
Detective!
Is Jung Woo Ju my only chance?
Not there. This way. Come.
Are you sure this is it?
(The date and place of the case October 30, 2003, 32 Hwanghwa-dong)
(Suseong-dong Case)
Write down how many you killed.
The elderly or the young girls?
You jerk.
Every single one!
Don't go any further than that.
What's with him? He keeps ticking me off.
How dare he smile? Stop smiling, you jerk.
Man, that jerk.
Gil Pyo, you should smoke outside.
Man.
Keep an eye on him.
And let me know right away once Detective Nam calls.
Yes, sir.
Do you think his words are...
worth trusting?
I don't think he's lying.
But we'll have to keep an eye on him.
Why don't you have any instant coffee in the office?
It means we can't spare any time to drink coffee.
You held out here for the last four years?
I didn't hold out.
I've been working well with pride.
I went to Mapo Police Station after getting a call...
that they might have a story.
When I went there, I saw a guy named Gu Young Chun.
He was there as a suspect for murdering sex workers.
This guy first said he killed and buried many young women,
then insisted he didn't.
He went on to say he remembers where he buried them, then not.
He kept talking nonsense.
Then he also said he killed the elderly too.
Isn't that weird?
Then three detectives of the Seoul Agency...
dragged that man together and left.
That's why I had no choice but to come down here.
I gave a thought...
on Gu Young Chun.
Do you think...
he's the one?
Don't you want to know where I buried them?
Isn't that why you brought me here?
- What happened? - Not yet.
I think we're almost done.
We're still waiting.
Let's check the bodies first.
What do you mean?
Seven. Eleven.
What? Eighteen people?
- What? - That crazy jerk.
Killed seven after breaking and entering a house?
Abducted and killed 11 women?
Could he be the same guy?
If he changed the MO, then it's possible.
MO? Are you talking about the method of his crime?
You're right.
If he wanted to feel something stronger,
there's a good chance that his MO could change.
Do you think he's the culprit for all those cases?
I doubt it.
No, we can't come to any conclusion right now.
Let's check everything one after the other.
Wait.
It doesn't matter if he's the same guy or not.
If what he said is true, this is a serious situation.
Make sure you keep this highly confidential. Understood?
And you should go with Forensics.
I'll go now.
Find out if he really buried those women.
Okay.
- Man. - How can he do this?
How is this possible?
Why? What's wrong?
- What's with him? - What's wrong?
Hey, Gu Young Chun!
Gu Young Chun, wake up!
- What's with him? - What?
- Gu Young Chun. - His head.
- Tilt his head. - Give me a pen.
What's with this jerk?
Man.
Shouldn't we call an ambulance?
Let's call one if he doesn't calm down in five minutes.
What did you do?
I didn't do anything.
Wake up! Gu Young Chun!
Get up. Hey.
(Police)
(Seoul Metropolitan Police Agency)
(Police)
Do you have epilepsy?
You still have to go to the scene.
We're ready.
Can you let me...
breathe in fresh air one last time?
Put the cuffs on him.
I want to use the toilet.
Gosh. Do you think this is a hotel?
(Gentle, Trustworthy Seoul Police)
Guard the entrance.
(Men's room)
(Keep your uniform neat.)
(Take a step forward.)
Hey! Catch him!
Take that. And...
Hey! Catch Gu Young Chun!
Hurry! Catch Gu Young Chun!
Gu Young Chun!
Hey! Stop him!
Gu Young Chun! Stop!
Go! Hurry up!
Catch him!
Catch that jerk.
Where did he go?
I'll go that way.
If we lose this guy, we'll be in big trouble.
Give out the wanted posters. And locate him as soon as possible.
We must be discreet for now.
So let's say he committed theft.
Yes. Let's do that. I assigned resources for you.
Focus on searching subway stations, train stations, bus terminals,
and any easy access points to run away.
- Yes, sir. - Okay. Go on. Now!
- Hurry up. - Okay.
I'm sending them out now.
Get the posters. Go to restaurants, motels, saunas,
and coffee shops. Just put them up everywhere.
So every citizen in Seoul can recognize this jerk's face.
- Got it? - Yes, sir.
Let me emphasize again. This is an emergency!
If we don't catch him, we'll be humiliated!
- Got it? - Yes, sir.
Run. Go out now!
- Go. - Go!
- Come on. - I'm sorry.
(New Star Motel)
We're from the police. Did you have a customer who looked like this?
- No. - Call us if you do.
Sure.
(The epilogue will air shortly.)
(Through the Darkness, Part 2)
I know today was a busy day.
You don't need to prepare a birthday meal for me.
What are you talking about? I want to.
It wasn't much of work.
To me, your birthday is as important as your dad's memorial day.
Happy birthday.
It must've been difficult to raise me alone.
So thank you.
No, I should thank you.
I wouldn't have been able to get through it without you.
I am proud...
of you...
because you have become a cop who can...
look into people's hearts better than anyone.
And I believe in you too.
You know that, right?
Yes.
Good morning.
You're here.
In 1, 2, 3, 4.
- Happy birthday to you - Happy birthday to you
- Happy birthday, dear Ha Young - Happy birthday, dear Ha Young
Gosh. This is so delicious.
- Dig in. - Hey.
Your mother is an excellent cook.
Gosh, it's just some food.
We're feasting thanks to you.
This chocolate looks great.
- Well... - That's expensive.
It was 35 dollars.
I like this. It's gotten so small.
You don't need tapes now. Just charge that.
- Really? - Can you hear it?
Hello. Check. This is great.
We got it. It's the hill in Nojin-dong.
- Right here! I found it. - Here too!
Here too!
Darn...
How's Captain Yoon?
Did you even help her, Song Ha Young?
Why me?
Why did you pick me for a position like this?
To get what I want, I must fully understand my target.
Song Ha Young, what are you doing? Are you going?
To do that, I must become Gu Young Chun now.
I am you now.
