What?

Do you know me?

("How Did the Profiler Catch Gu Young Chun?")

Gu Young Chun.

You're the guy who caught him.

So you know who I am.

I guess you were very interested in Gu Young Chun's case.

He took the credit for my killing.

That was a ridiculous lie.

What do you mean?

I'm not here to interrogate you.

I'm here to help you.

You want to help me?

But why?

Why would you help me?

My job is to analyze why this happened,

so I'm here to speak with you...

to learn more about you.

Speak about what?

Well, anything.

Do you live alone?

- Then who do you live with? - My mom and brother.

What about your father?

He died.

A long time ago.

- Thank you. - Thank you.

(CSI Scientific Investigations Field Training)

(Special Lecture by Chief Kook Young Soo)

(1 missed call, Detective Nam Il Young)

(Calling, Detective Nam Il Young)

Detective Nam, I just saw that you called.

- Chief Kook. - I had a lecture...

at the Police University. I saw it just now.

It's a robbery case. They said it seemed suspicious,

so Captain Yoon and I took a look.

It reminds me of timid aggression.

I think there's something.

(Yeongdeungpo Police Station)

I told Inspector Song right away, and we rushed here together.

Yeongdeungpo Police Station.

- Good day. - He's trying...

to get a confession out of him.

You were convicted of theft and rape in the past.

You were in jail for quite a while.

I got caught because luck wasn't on my side.

I didn't really get to do what I'd wanted to do.

Luck wasn't on your side?

Had I been lucky, I wouldn't have been caught.

Didn't you break into the apartment in Sinheung-dong to steal money?

Yes.

But you only managed to steal ten dollars.

- Once again, you were unlucky. - Exactly.

Who knew they'd be so poor?

Why did you leave the valuables untouched?

Stealing stuff like that could leave a trace.

I only steal cash.

You're very cautious.

Yes, I am.

I'm very thorough when it comes to these things.

- Like Gu Young Chun? - He's a bluffer.

How do you know?

I could tell right away.

You're right. I met him.

He indeed is a bluffer and a loser.

How many people did he say he killed?

Why do you ask?

I think he's lying when he didn't even kill that many.

He said he killed all those people.

I know. You're right.

The Imyeong-dong murder.

That wasn't him.

You're a good judge of character.

You've never even met him.

I know these things.

But I have to say,

I've never seen a robber with a pipe wrench.

Why did you pick such a heavy tool?

Because I may have to kill them.

Why do you have to kill them?

Goodness. They saw me. That's why.

Are you really a detective?

But most robbers use knives. Am I wrong?

When you stab someone, they don't always die.

- How do you know? - Well...

That's...

You know everything.

I know a thing or two when it comes to this stuff.

But there are more affluent neighborhoods.

Why Sinheung-dong, if you needed money?

Many rich people from Gangnam have moved there.

I was going to walk around the area and pick my targets,

but I couldn't even do anything because security was so tight.

So you changed your plan and targeted low-income buildings.

Poor people can't afford to worry about security,

so they had no choice.

Don't you feel bad for them?

Why should I?

It's their fault for being poor.

- Then why did you start the fire? - What?

I...

That wasn't me.

I didn't do it.

I didn't start the fire.

I didn't do it, the fire.

All right, we can talk about that again later.

Being with strangers 24-7 in jail must not have been easy.

I know what it's like.

How do you know?

I'm an introvert too, just like you.

When I'm keeping to myself, people assume I don't know anything.

They all look down on me.

Totally.

Everyone thinks I'm an idiot!

The detectives here won't hit you.

And no one here thinks you're an idiot.

Everyone here...

understands you.

Everyone...

hated me.

Everywhere I went, I had to suffer and get beaten up.

I even had to put up with that awful thing.

When?

- When I was little. - How old were you?

When I was in elementary school.

Who did that to you?

My neighbor, an old man.

That must've been a lot to handle for a kid.

Do you want to keep talking to me?

Yes.

Then answer every question the detectives here ask you.

Do that, and we'll talk again.

I don't want to go back to jail.

Whenever I think about that time, I feel crazy.

I get so upset and angry, to the point that I'd rather die!

If you struggled that much,

why didn't you speak with the correctional officers?

I complained numerous times,

but no one listened.

I...

The people here will listen to everything you say,

so don't worry and just tell them.

And then what?

What will happen after I tell them everything?

What will happen if you don't tell them everything?

I'm sure you don't want...

to relive the misery you experienced.

I'll tell them everything I did.

Get me a single cell.

A single cell. That's all I ask for.

Mr. Nam Ki Tae.

The detectives here know all about the Imyeong-dong case...

as well as the Mogu-dong arson case.

So I suggest you confess voluntarily.

Okay.

Let me know if you need anything.

I'll help you.

If you're willing to open up and confess,

the detectives here will be all ears.

Everyone here...

wants to hear you out, just like I do.

But the thing is,

I don't remember every single thing I did.

I just walked around and did it whenever I felt like it,

so I don't think I can recall where each one took place.

That's okay.

Just tell us what you remember. You can take your time.

I will be...

sentenced to death anyway, won't I?

Don't think like that.

We have to talk again, you know?

All right, then.

(Through the Darkness, Part 2)

(Episode 10)

(Interview Room)

(Criminal Investigation Division)

You're here.

Yes.

(Serious Crime Unit)

- What if that's the case? - No way.

- He's here. - Hello, sir.

How did it go?

- Can we go in now? - No, wait.

The Southwestern Case. It was Nam Ki Tae.

- See? - I told you.

The Imyeong-dong case too.

- That was also him. - What?

- Goodness. - Unbelievable.

Did he confess?

Yes.

Gosh, we went through so much because of that case.

We should be strategic about interrogating him.

Okay.

He's emotionally unstable.

And he seems socially inept.

He struggles to communicate with others.

I knew it. I thought he looked like a dimwit.

He's never formed a relationship...

with anyone who supports his words and actions.

Then how should we go about interrogating him?

If we get angry or yell,

he won't want to talk.

We have to humor him too?

I'm not asking you to praise him for his crimes.

These suspects already know what the detectives are after.

Even if you treat them nicely, they won't trust you.

She's right.

If you seem to overly approve of what they did,

it can actually backfire.

Then what should we do?

First off, try to avoid showing him any kind of judgment,

be it positive or negative.

Try as hard as you can to let him do the talking.

Nam Ki Tae has a high tendency to be socially withdrawn.

He'll become anxious if there are too many detectives around him.

So we'll have only a minimal number of people in there.

Why are there so many rules over a simple interrogation?

There has to be.

As everyone here knows,

Nam Ki Tae is unlike any other violent criminal.

The victims of the Southwestern Case that we are aware of...

come to a total of 14.

Among them, six died.

And there is a high possibility of many more victims.

This means we cannot miss even one innocent victim.

That is how we can be responsible in this current situation.

Also, you should not throw random questions at him.

He has poor communication skills, so if he gets confused,

he might blurt out just anything.

From now on, we should write down our questions beforehand.

That is a good idea.

If you don't, he might agree with even the wrong parts,

then give up on making a statement.

(We'll be quick, kind, and fair as advanced first-class police.)

And one more thing.

Until the interrogation is over,

pick out one detective...

who converse with the suspect the most efficiently.

It'll be the most effective in getting the answer you want.

(Seoul Metropolitan Police Agency)

(Police)

(Parking Lot)

Nam Ki Tae was...

raped in his childhood.

By whom?

He just said it was an elderly person in his town.

Around when in his childhood?

In elementary school.

He didn't want to elaborate,

so I didn't press him.

Nam Ki Tae was charged for rape a few times, right?

From child rape to adults, at every age.

There is no crime he stayed away from.

So how did you get him to confess the Imyeong-dong case?

He was conscious of Gu Young Chun.

He said Gu Young Chun was showing off with something he did.

So I provoked him and asked.

How amazing.

Were they competitive or something?

Let's go inside.

You walked around?

Once I got off the subway, I always walked from there.

It's a pretty long journey to the apartment in Sinheung 6-dong.

I'm really fit.

I ran ten laps a day.

Ten laps a day?

I had to run fast to avoid getting caught.

How did you choose your crime sites?

I didn't choose anything in particular.

I just walked into desolate places.

- Just blindly? - Yes.

People rarely lock their balconies and windows.

Breaking news.

A leading suspect who terrorized the residents...

of the southwestern area of Seoul in 2004 was caught.

Last night, he broke into Im's house in Sinheung 6-dong,

in an attempt to steal money.

But after a fight with Im's father, he was caught...

and handed over to the police.

The suspect is Nam, a man in his 30s.

Currently, the police stated Nam has admitted...

to all charges of serial assault and murder...

in the southwestern area,

and they are now interrogating him for additional crimes.

It's me.

If you get a call from Seoul Station or Yeongdeungpo Station,

quickly hand over the files on the cases in Gyeonggi Province.

(Superintendent Heo Gil Pyo)

Those guys?

Yes, they're the real deal.

Of course, I've worked with the Analysis Team.

What they mostly do is...

talk to people like Nam Ki Tae.

They're unbelievably good at creating the atmosphere...

to fish out a confession from these suspects.

Do you think they yell at him and press him in the investigation?

How is the investigation going?

He confessed to most of his crimes.

In order to increase the credibility of his confession,

we are doing our best to inspect the scene...

and secure the evidence.

What was his motive?

We are yet to put our finger on something certain.

We can only assume.

So far, we presume it's the anxiety from violence and beatings...

and the intensification of social withdrawal,

so a combination of such factors can be the reason for his behavior.

Was the Southwestern Serial Murder all done by one person?

Well, it's tough to come to a conclusion at the moment.

The total of serial murders in the southwestern area...

come to 11 cases.

Guro, Geumcheon, Gwanak, Dongjak, and Yeongdeungpo.

These five jurisdictions are investigating in cooperation.

One second.

Excuse me. Coming through. Let me come through.

May I see your ID?

(Nam Ki Tae's home)

Good work, everyone.

In Tak.

Hey, Young Soo.

Where's Nam Ki Tae's room?

We didn't get there yet, but I think it's this one.

Look at this jerk.

- In Tak. - Yes?

Yes.

And?

This has to be a real knife.

I'm cuffed anyway, so can you give me a real knife?

You jerk...

- One second! - Can you move?

Hey, quiet.

That's the only way I can remember better.

- You wicked man! - Darn you!

Hey, block them.

- You jerk! - I can't see it!

Did you rape her too?

Did you do anything to her before?

Hello?

Hey.

I need you to come here for a second.

Okay.

Bring my daughter back!

You cursed jerk!

Bring my daughter back!

What did you do next?

So the victim fell.

Then you stabbed her more, right?

(Newspaper)

This afternoon, Nam Ki Tae,

a suspect of the Southwestern Serial Murder Case,

conducted the reenactment for Pureumae Park Murder Case.

The police announced today that they will also conduct...

a reenactment of the Gocheong-dong Murder Case...

and the Mogu-dong Arson Murder Case.

Shocking, isn't it?

I knew it seemed odd.

He recognized me at first sight.

Nam Ki Tae did?

Yes.

We should refrain from exposing the identity of our officers.

This isn't some kind of a film.

It wasn't because I wanted to.

There is this guy named Im Moo Sik.

A reporter that I don't like.

He put his photo in the article without asking.

Is he insane?

Well, I guess he didn't think things would be like this.

No one could have imagined.

Hey, take a look at this.

All of these are articles on the Southwestern Case.

("Mogu-dong Arson Murder Case")

It looks like he scrapped the articles for his crimes.

I'm sure there are many more...

other than these.

Why did you set the place on fire?

Me? Fire? What fire?

Why are you suddenly asking him that?

Why did you set the place on fire?

Why are you asking us?

Is this...

about Nam Ki Tae's arson?

You're right.

If he didn't set the place on fire,

he should react like you two, as if he doesn't know...

what I'm talking about.

And? Did he say something else?

Yes.

First, he was flustered at the question.

Then he answered me like this.

I didn't start the fire.

I didn't do it, the fire.

What kind of nonsense is this?

Nam Ki Tae is the perpetrator...

of the Mogu-dong Arson Murder Case.

- What? - What now?

Keep your focus on that case and start pressing him.

- Young Soo! - Yes?

I need you here.

Why? What is it?

What is this?

This guy isn't just an ordinary criminal.

This explains why we never got his footprints.

Nam Ki Tae also did everything he could to commit murder.

Young Soo.

Take a look at this.

What's this?

(Food good for eye health)

"Food..."

(Food good for the heart)

This is ridiculous. Darn it.

He was fine with harming people,

but he wanted to live a long life?

(Tomatoes are high in lycopene...)

("The Best Benefit of Hiking Is the Way We Walk")

An eyewitness said he ran away very quickly.

The statement was correct.

He even studied how to run away quickly.

I bet he's hiding the murder weapon somewhere in the house.

Do you really think he kept it in the house?

You watched his reenactment on the news, right?

I did.

Gosh. How can anyone make that facial expression?

It really creeped me out.

He gets off just by thinking about the act.

- He solely kills for pleasure. - Right.

So he must keep the murder weapon somewhere in the house.

I doubt he threw it out.

Then let's look for anything that could be used as murder weapons.

Yes, sir.

Find everything that might be a murder weapon from now on.

- Yes, sir. - Yes, sir.

You came through the balcony.

(Reenactment for the Mogu-dong Arson and Murder Case)

Being timid during the act is his unique factor.

(Suspect)

You headed to the smaller bedroom.

(Victim)

Wrap it up.

- Hey. - Hey.

Hey! Take it.

- Step back! - You murderer!

- Please step back. - You murderer!

- You need to move back! - Step back!

- Murderer! - Hey!

- Just one comment! - You murderer!

- Step back. - Die!

- Hey, stop him! - Stop him!

- Die, you murderer! - Get him to stop!

Move back!

- Stop them! - Die!

- Stop them! - Just one comment!

- Put him in the car! - You murderer!

- Stop, and step back! - Get him to the car.

- Just one question. - Step back.

- Okay. Go! - Hold on!

- Step back! - Stop!

- My baby... - What about my baby?

- Bring my baby back! - You murderer!

Calm down!

- Murderer! - Stop! Step back!

- You need to step back. - My baby...

The suspect of Southwestern Serial Robbery and Murder Case...

performed the reenactment of the murder at the crime scene today.

The victim's family who had to watch the indifferent behavior...

of the suspect trembled in rage once again.

The lack of remorse from the serial killer during the reenactment...

brought pain and shock...

to the victim's family as well as the neighbors again.

("Nam Ki Tae, Addicted to Killing, How Many Did He Kill?")

("Serial Murderer Gets Hooked on Killing")

Are they shocked or having fun?

Look at them. They are having a field day.

What's there to think about?

Your headline should start...

with his name and an exclamation mark. Okay?

This is the best time to get our view counts up.

Do we also have to publish the same articles like everyone else?

You're not desperate enough.

You said you didn't want people to look down on you.

We already have so much on our plate.

Why are you worrying about this?

Get a grip, Reporter Choi.

Do we have to join this circus too?

Let's clear something up.

You can't seriously be asking me about that.

If we don't, we'll fall behind again.

Stop following your ideal. Just write your article.

"Nam Ki Tae" and an exclamation mark.

Okay?

Gosh. Am I...

doing this right?

How did you know that he had a social phobia?

Well, we didn't get it diagnosed by a doctor or anything.

We were only commenting on the suspect's characteristics...

like how he rarely talks and is introverted. That's all.

How much did he steal so far?

We're investigating the robbery cases separately.

When we arrested him, the amount of confirmed robberies...

was ten dollars in cash.

- He did that for 10 dollars? - Just for 10 dollars?

Then could we interpret that he didn't commit these crimes...

to steal money or valuables just like Gu Young Chun?

Yes. That's right.

For now, we believe this was his way of expressing...

disapproval of our society.

(Nam Ki Tae, crime scene reenactment)

What are you doing here?

I have zero interest in Nam Ki Tae.

What a surprise.

I thought at least I should be writing about something else.

When everyone in the country is focused on Nam Ki Tae?

Hey, the most searched word is Nam Ki Tae.

Just his name.

Right.

I think someone should be writing about the people...

who are left behind, not Nam Ki Tae.

("Remorseless Suspect, Unchanging Society...")

- Here's your coffee. - Thanks.

(Fact Today)

- Hey, Woo Ju. Do you still draw? - Yes?

- Draw what? - You told me...

you draw sketches of victims whenever you have time.

Why do you ask?

- My baby... - What about my baby?

- Bring my baby back! - My baby!

That just crossed my mind.

I hope you'll keep doing that.

Okay. I will.

("Southwestern Serial Murder Case: Who Is This Man?")

(Deco Plaza)

What are you staring at?

I was just frustrated.

I was just wondering about...

what people on the street were thinking about.

"What should I eat today?"

"What should I bring home?"

"I'm late for my appointment."

"My boss is so annoying."

They are probably thinking about their day-to-day life. Right?

I can't even remember the last time I thought about...

my day-to-day life.

It does feel like we're running...

in a race that's never going to end...

when I see these criminals,

crawling out here no matter how many of them we put away.

Some people in our country are being brutally murdered.

But some people from the same country have peaceful days.

Nothing has changed in this world.

In life...

and especially in our line of work, we see more evil than good.

But it's quite sad at times that we can't have hope...

in people.

Whenever I try harder to have hope,

I end up facing criminals that are smarter and more evil.

You have more interviews left with Nam Ki Tae, right?

I should interview him before the prosecution takes him.

"He who fights with monsters..."

"should look to it..."

"that he himself does not become a monster."

"If you gaze long into an abyss,"

"the abyss also gazes into you."

Nietzsche, right?

"Remorseless Suspect,"

"Unchanging Society,"

"and Shameless Media Bring Tears to the Bereaved Family."

The victim was an average college student.

Afraid of going out alone,

the student still cannot return to school.

And another victim had to be buried in the cold underground...

instead of enjoying the days of youth.

Only blackened marks of the fire...

remain with this happy family.

A playful daughter...

faced a wrongful death even without having a chance to say goodbye.

Some people lost their loved ones overnight.

And these people aren't strangers to us.

They are our neighbors and family.

We found this knife.

But there was no luminol reaction.

Gosh. This is driving me crazy.

Seeing how he cut the soles of his shoes,

I'm sure he's the culprit.

We need to find the victim's DNA.

No way.

He already confessed to everything.

We're not going to be forced to cut him loose, right?

If we don't have any supporting evidence,

he will only be indicted...

for the break-in and aggravated robbery.

On top of that, if he recants his confession, we'll have nothing.

We must find more evidence.

Actually, Chief Kook and Inspector Song...

went back to his house to look for more evidence.

But I get the feeling that he might have tossed the murder weapon.

This place has a similar vibe to the crime scene.

- Right? - The districts were different,

but he must have chosen a familiar environment subconsciously.

We should link cases to see if there are incidents that...

took place in a similar environment.

- I'll tell Woo Ju. - Okay.

The detectives can't just sit back and wait until Nam Ki Tae talks.

Right.

- Let's go in. - Okay.

Do you really think it's here?

He's obsessed with murder.

Let's look for it.

I've already checked that room.

Help me pull out this closet.

One, two, three.

Here?

He didn't even bother to wipe the blood off.

Professor An, hang on.

Did you see this?

Hello?

I see. Thank you.

Captain Yoon.

They found Nam Ki Tae's kitchen knife.

So it really was there.

Yes, under the closet. He didn't even wipe the blood off.

He's a total lunatic.

I just got a call from the NFS too.

While examining the pipe wrench, they found hair...

and an old bloodstain.

So he can't even deny it now.

When are we sending him to the prosecution?

It's scheduled for next Friday.

The Analysis Team will interview him before that, right?

That's right.

Inspector Song must be under a lot of stress.

He has to speak with that psycho again.

(Southwestern Serial Murder Case)

The police confirmed...

Nam Ki Tae's two additional crimes after lifting the victims' DNA...

from the weapon found at the home...

of this robbery and serial murder suspect.

The headline should be "'Memories of Murder' in Seoul."

Hurry!

- Take care of this. - That's not the situation now.

Hey, bring it over here.

(Another Victim's DNA Found)

Serial murderers like Nam Ki Tae...

can show up anytime.

It's important to look after one another and pay attention to...

(Sinheung 2-dong Case Report)

(Sinheung 2-dong Case Report)

Are you going to be okay alone?

Knowing how Nam Ki Tae is, I have to talk to him one on one...

to get more out of him.

We meet again.

I told you that we'd talk again.

So how did it go?

Did the detectives listen to what you had to say?

Yes, they're good listeners.

Let's talk casually.

I'm older than you, so I'll drop the honorifics.

Sure thing, all the other detectives talked to me casually anyway.

Do you remember telling me that you had a hard time in jail?

Of course, I do.

My cellmate who was a thug beat me up to a pulp.

- Why? - For no reason.

He just beat me up because I couldn't say anything.

I mean, because I wouldn't say anything.

He must've been so surprised when he saw me on the news.

That scumbag.

Is that gratifying for you?

"Gratifying?"

That I'm not sure.

But I bet he had no idea I'd walk around with a knife...

to kill people.

He must be in shock now, right?

You said you were sexually assaulted as a child.

Do you remember?

You said it was a neighbor, an old man.

Right.

How old were you at the time?

I was ten.

He dragged me into the woods...

and tied my fingers with my shoelaces...

Hold on.

He tied your fingers?

Yes.

He dragged you into the woods...

and tied your fingers...

with your shoelaces?

By any chance,

is there a sexual assault case Nam Ki Tae confessed to?

No.

Then see if you can find a similar case,

where the victim was found in the woods with fingers tied...

with shoelaces.

I'll see what I can find.

Victim found in woods, shoelaces.

Sexual assault or murder.

See if you can find a case that matches.

A man did that to a little boy. It was awful.

It must've been traumatizing.

I was very young, so I didn't know what to think of it.

But I was scared whenever I saw him after that incident.

That was only the beginning though.

What do you mean?

My next-door neighbor did it to me twice when I was in high school.

And it happened again when I was in the military.

I was like everyone's punching bag.

Why didn't you call the police?

I didn't want to.

I was too shy and couldn't even get angry at anyone.

You must've had friends though.

At school or in the military. You must've had someone.

No, I never did.

They all either tried to use me or bully me.

No one wanted to be my friend.

What about your teacher? Your teacher at school.

My teacher?

The teachers weren't any better.

What's that thing...

where teachers record their observations of students?

- Student record? - That's right.

All through school,

mine said, "too reliant, passive, lacks independence."

Those three things were always on my student record.

That's why I still remember those difficult words.

"Reliant, passive, lacks independence."

Didn't it make you angry?

It made me very angry.

But I rarely show it.

Do you want to hear my story?

You have something else to tell me?

You haven't heard my story yet.

I wanted to commit a perfect crime.

Once I found out that I was good at something,

I wanted to be better at it.

- That's why you studied? - Yes, I studied so hard.

I read books.

And whenever they said important stuff on TV,

I jotted it down.

I saw your notes.

I wrote down everything that could be helpful.

Some of your notes were about health.

Why were you so health-conscious?

Because I need to live a long life.

And why is that?

That way, I can kill more people.

Gosh.

(Secure Interview Room Instructions)

- Goodness. - Oh, you're here.

My gosh.

Do you remember what your first offense was?

It was back in elementary school.

I broke into an empty home then stole their money and valuables.

- What about rape? - I can't really remember that.

I mostly went for kids when I was younger.

They do as you say.

- How young were the kids? - Elementary school students.

What is the psychology behind that?

That's why what children experience is so important.

They accumulate things without even knowing.

Of course, not everyone will become a criminal...

from a bad experience.

But kids can't manage situations themselves.

In the case of Nam Ki Tae,

he accumulated all of his repeated traumas.

I think that influenced his character-building greatly.

What if, in order to break away from the negativity,

he voluntarily assumed the role of a killer?

That might be it.

About three years ago,

I started to think about killing people too.

Three years ago?

That's after you were released from prison.

- Yes. - Did you not think...

to live straight after being released?

Not really.

There's no changing me, so why bother trying?

Instead, I felt a bigger thrill once I got released.

I wanted to try stabbing people...

and strangling them too.

Because you felt wronged for the beatings you got in jail?

Of course I felt wronged.

You have no idea how much I wanted to kill the punk who beat me.

Then you should've talked to the guy directly.

Why did you let your anger out on strangers?

I wasn't letting my anger out.

That's not the reason.

I just did it because I liked it.

- You did it because you liked it? - Want to know something?

When I see the person dying in front of my eyes...

flapping their arms and legs.

My heart starts to race.

That's when I finally feel a little alive.

You felt alive...

while watching someone dying?

It's truly euphoric.

That's why I can't quit.

Can't quit what?

Killing, of course.

I could quit smoking, but I couldn't quit killing.

Didn't you ever think to stop?

No.

I mean...

even not killing for a few days drove me crazy.

So I didn't even try.

That lunatic.

That was the reason why...

he turned his victims around in a bright place to see their faces.

There's a case from January 2004 in Bongu-dong, Bucheon.

A ten-year-old boy was kidnapped, raped, and murdered.

I'll print the materials for you.

(Bongu-dong)

(Bongu-dong, kidnapping and murder)

("Bongu-dong Elementary Student Murder Case Left Unsolved")

("Reported missing 21 days ago, 11 days since the body was found.")

Does anyone happen to know about...

a case from two years ago in Bongu-dong?

Where a ten-year-old boy was kidnapped, raped, and murdered?

I saw it when I was picking out cases for us to work on.

Bongu-dong?

Isn't that the cold case from two years ago...

that was extensively reported about?

Give me the fax number here, please.

(Receiving scan)

I guess the more I watch them...

the more I want to try something more violent.

That's why you kept changing your murder weapon.

At first, I liked the feeling of strangling someone.

That feeling when they flap about as they run out of breath.

It was more euphoric than I had imagined...

when I tried it myself.

You keep using the expression, "euphoric."

I feel like it expresses the best feeling.

Anyway...

After I came home that day, I slept like a baby.

- Because you felt euphoric? - Yes.

Oh, right. Then I tried using a knife.

I tried it and once I saw the blood spurting out, it drove me crazy.

I was so happy. It was so thrilling.

I sometimes went back to the neighborhood I killed...

and reminisced about it too.

- Reminisce? - Yes.

You liked the knife so much.

So why did you switch to a pipe wrench?

I wanted to feel a different sensation from a knife.

Was that after Pureumae Park?

Maybe.

I get a little confused because there are so many.

When I used a small knife, they wouldn't die very easily.

So I got frustrated and switched to a kitchen knife.

But even the kitchen knife didn't really do the job.

It got me annoyed and angry for some reason.

It made me uncomfortable and annoyed if they didn't die.

Why would you get annoyed?

That should not happen in a perfect crime.

I was trying to commit the perfect crime.

So I didn't even rape the girls I killed.

- In case you might leave evidence? - Yes.

No matter how hot it was, I didn't take my gloves off.

Even though the gloves dulled the sensation a little.

The steel pipe had its perks too, so it was all right.

It was a necessary inconvenience...

as I wanted to kill many for a long time.

What is the sensation that you're talking about?

The head is the weakest part of a human.

The moment you strike down like this...

Gosh. Words can't explain this. You have to try it for yourself.

A ton of blood starts spouting out.

At that moment when I look at their faces as they're flapping about.

The moment drives me insane. It excites me so much.

I feel like I'm about to die. Really.

Looking at it makes me so happy. It feels amazing.

You've never tried it, so you have no idea.

Gosh, I can't listen to him anymore.

How does he stand listening to him?

This isn't a job for the weak minded.

I have a weak mind.

I'm going to step out for a moment.

I need to pee.

- You want to use the bathroom? - Yes.

Hold on. The detectives will be here.

- You'll wait for me, right? - Yes.

I will be right back.

Sure. Take your time.

You're back.

You gave me a signal just now, right?

Yes.

You think this was Nam Ki Tae's doing too, right?

I do.

The way the ten-year-old boy's fingers were tied up...

by a shoelace.

It's the same thing that happened to Nam Ki Tae in his childhood.

We'll have to interrogate him then.

How far does his area of crime stretch out too?

I'm going to go back in.

Ha Young.

(Criminal Investigation Division)

You can leave it to the detectives in charge here.

There's no need for you to do everything.

Nam Ki Tae and I already formed a rapport.

I'll get his confession the fastest.

Yes, that's true.

But all those horrible things that he's pouring out...

There's no need for you to bear it all yourself.

I wouldn't have even started...

if I was going to avoid it.

You're right.

I worried for nothing.

I'll be back.

(Criminal Investigation Division)

(Interview Room)

You get scared easily, don't you?

- Me? - You seem that way.

Seeing how large Korea is, you chose to commit crimes...

only around Seoul and Gyeonggi, in neighborhoods close to you.

What if I get caught by going to a foreign place?

It was for your perfect crime?

That's why you ran around with all your might?

How did you know I run every day?

- You ran every day? - You didn't know then.

I was shocked for a moment because I thought you knew that too.

I did see that you wrote down running methods in your notes.

I ran around the school's field ten times.

I didn't miss a single day.

Which is why running is the one thing I'm super confident about.

Wait, no.

I'm good at killing people too.

Once I went to a couple of different neighborhoods,

it made me want to visit Busan too.

I wasn't able to go because I got caught though.

Didn't you get scared, once the news started to...

- focus their attention on you? - Why would I be scared?

You might get caught.

Gu Young Chun.

That punk said he was scared, right?

Why are you suddenly bringing Gu Young Chun up?

That punk is a loser.

I liked trying to avoid the police.

I liked the thrill it gave me.

- Thrill? - Yes.

Do you still feel no remorse towards those people?

Why would I feel remorse?

I'm not sorry at all. I don't even feel guilty.

All I wanted to do was kill more people.

When I saw what I did here and there on TV,

I felt like I became a hero.

I became proud, thinking that I killed that person.

Then I felt like the TV...

What was that?

You said you felt like a hero and became proud, right?

You took a ten-year-old kid to the woods in Bongu-dong,

tied up his fingers with shoelaces,

then committed the atrocity...

you experienced to that little kid.

Isn't that so?

Why are you suddenly getting mad at me?

Will anything change even if I said anything?

If you don't confess what you did,

people like Gu Young Chun will bluff and claim that they did it.

Darn it.

I did that.

(On January 5, 2004, Jung was playing soccer with his friends...)

What was he doing at that time?

- He was playing with a ball. - Doing what?

Soccer.

Happy now?

And I'll share the details with the detectives here, right?

Then can I go back to what I was saying?

Do you enjoy discussing something like this, Nam Ki Tae?

It's fun.

It's the first time anyone listened to what I said.

Why do you think people don't want to talk to you?

They're all normal, but I seem like a psycho.

A psycho?

You know, confused and anxious.

This confusion often drives me insane too.

I'm sure I'd seem weird to others too.

And you were freed from such emotions when you killed?

I told you already.

That's why I can't stop.

When you stab someone,

I avoid places that will spurt out blood,

so I go with the stomach or the side.

Then the moment the knife goes into them,

they can feel it with all of their five senses.

You should've seen their faces.

I want to do it again.

I think you're less than a beast.

What do you think?

You're not a hero.

You seem like an angry lunatic who just throws his knife around.

You're right.

I never denied that.

- Let me continue. - You're going to continue?

I couldn't share this with anyone, so I was really frustrated.

It's now or never, right? So stay and listen.

Among many ways of killing,

my favorite is hitting someone on the head.

As I mentioned before, it's the flapping.

It feels awesome to watch them flap about.

Once I kill someone like that,

the ecstasy stays with me for a week to half a month.

But after a while,

the impulse comes back and it's even worse.

Then as my impulse gets stronger,

there is no other way...

than going out and killing someone.

I promise. Just once more. I want to go out and kill someone.

I need to feel that ecstasy.

Detective.

- Detective? - Yes?

Are you listening?

- Nam Ki Tae. - Yes?

Do you think it's unfair that you were caught?

It is unfair.

If I didn't get caught,

I would've lived my life traveling around the country,

becoming the best serial killer in history.

It's a lot of shame when I think about that.

I can never do this again.

You're right.

You won't be able to do this anymore.

- I think it's a relief. - It's a huge relief.

I was really worried.

- He's here. - Ha Young is back.

- Oh, he's here. - He came back.

(We'll be quick, kind, and fair as advanced first-class police.)

He made a confession regarding the Bongu-dong case too.

- Nam Ki Tae is unbelievable. - My gosh.

Words got around about you for a reason.

I didn't think he would continue to confess until today.

Good work.

Thanks for the tough work.

Yes, let's go.

- Good work. - Good work, everyone.

- Good work. - Good job.

- Good work. - Great work.

Wait, Inspector Song.

I heard this was yours. I was told to keep it well.

I almost forgot.

Thank you.

(Happy and secure residents with sincere Yeongdeungpo Police)

Why are you throwing this out?

Nam Ki Tae used that.

(The police will always be with our citizens.)

Over here!

- Nam Ki Tae! - Look over here!

- Move aside. Move. - Look over here!

In 2004, the kidnapping and murder of an elementary school student...

in Bongu-dong, Gyeonggi Province almost remained unsolved,

but this case was also found to be the crime of Nam Ki Tae.

This afternoon, Nam Ki Tae was sent to the prosecution.

He confessed to all the crimes he committed in the past two years.

The crimes include 3 murders and 5 attempted murders...

in the southwestern area of Seoul,

Mogu-dong Arson Murder Case,

Imyeong-dong Murder Case,

two murders in Gunpo, Gyeonggi, and in Bongu-dong,

- the kidnapping and murder. - Yoon Ji.

You really refuse to go out and cover this case?

The prosecution plans to conduct additional investigations...

- Then what? Should I go? - into seven murders and arson...

- Fine, I'll go. - among the cases from the police,

then they will decide whether to indict him additionally.

- Nam Ki Tae! - Nam Ki Tae!

(Yeongdeungpo Police Station)

(Ministry of Justice)

Choi Yoon Ji isn't so bad, but she never gets it right.

Song Ha Young throws him a bait, then Nam Ki Tae gives him...

the whole story.

Why the heck is she going on about people who are left behind?

I'm telling you.

He looked straight at the victims when he killed them.

What do you think was on his mind?

It'd be awesome if I can get an interview on that.

Bye.

Goodness, Inspector Song. Hello...

What? What are you doing?

You aren't so different from Nam Ki Tae.

What did you say, you jerk?

Are you insane?

Darn it, let go. Let go of me.

How dare you disrespect a reporter like this?

You're going to regret this.

I'll sue you immediately!

Listen up.

You completely disregard the victims saying you have the right to know,

as if you reporters are something.

You should be thankful that I'm not suing you first.

That's for using my photo without permission.

That crazy jerk.

- Who made this? - Gosh, that's nice.

- Daddy. - Look at Daddy.

- How do you feel? - That's it.

The weather is wonderful.

Thanks for making gimbap, babe.

What should we eat for dinner?

How about pizza?

Hey! Wait for me!

Detective.

- Detective? - Yes?

Song Ha Young.

Detective.

Blame her bad luck.

It is her fault for catching my attention.

Look at me.

I ended up in here trying to get some freebies.

Well, I wouldn't say I have the right...

but killing is sort of like a job of mine.

Because I need to live a long life.

That way, I can kill more people.

Every time I saw her just putting up with it,

it made me so angry.

Arms and legs... Cut them off...

and divide them into two. How many do you have?

You know the bathroom threshold?

The threshold is...

the line that separates the living realm and underworld.

The line between life and death which is decided and ruled by me.

(Emergency Ward)

Ha Young! Please help!

My son fell into the water!

Oh, no! What do I do?

Do you know how scary it is when you're deep underwater?

She must've been scared and sad.

- Sway - Sway

- Her hair sways away - Her hair sways away

- Just like - Just like

- The whiskey in the glass - The whiskey in the glass

- Her hair - Her hair

(Tojung-dong, Anyang, Gyeonggi Province)

Gosh. It's freezing.

I'm trying to go to Daejong Lake. Which way do I need to go?

Pardon?

I'm not dangerous.

I've never been here before.

There.

Turn right at the intersection up ahead. And then go straight.

When you see another intersection next,

- you can turn left... - Where are you going?

Pardon?

If you don't mind, I can give you a ride.

No, it's okay. I can take the bus.

I'm not dangerous, you know.

I'm driving down anyway.

If you're going in the same direction, I'll give you a ride.

Meanwhile, you can tell me how to get to Daejong Lake.

That will be helpful for me.

Don't you have to wait for a long time for the bus?

You must feel uncomfortable.

Then could you tell me how to get there one more time?

Turn right at that intersection.

What was that?

You'll see a smaller intersection.

- Then turn left there. - Hold on. Let me write it down.

Gosh. I don't even have paper.

Why don't you get in and make things easier for both of us?

Aren't you cold?

Then I'll accept your offer.

Of course.

Please get in.

- You must be freezing. - Thank you.

You must like dogs.

You can drop me off somewhere over there.

You can turn left over there.

Right here. This will do.

Wait. You missed it.

I had to go right from there.

Drop me off here, please. I'll get out here.

Hey. Stop the car.

What are you doing?

What are you doing? Stop the car now!

I want a quiet ride.

Stop the car now!

If you don't, I'll call the police!

I'm calling the cops.

Open the door. Open it!
