(Missing Person: An Yu Yeon)

That's too blurry.

That won't be enough...

for us to confirm if the woman next to him is...

the missing woman or not.

Come on. You guys have good eyes. Take a closer look at him.

We just installed those cameras,

so they're better than what we're used to.

Young Soo kept pushing for them too.

It's blurry,

but the vehicle was spotted...

around the locations where the women went missing.

Detective Nam, did you run the license plate?

I put in a request for tech support.

We used the security cameras to track him on the same night.

But we couldn't track him after the 5km mark.

We can suspect that he probably went to someplace secluded.

If he's our guy,

he probably abandoned the body right away.

Yes.

Woo Ho Sung?

Okay.

A 38-year-old man, Woo Ho Sung.

They faxed us the information...

- of the vehicle owner. - Okay.

The vehicle owner is Woo Ho Sung, a 38-year-old man.

He works at an acupressure massage parlor.

Why does he look so normal? This is so creepy.

People who seem so normal are good at scamming people.

Shouldn't we check his alibi first?

I'll take Detective Nam with me.

- Okay. - All right. Then...

can you pay attention to his reaction...

when you meet him for the first time?

- Sure. - I already know.

I bet he'll say he didn't do it.

He'll probably deny everything even if he did it.

Right. He'll deny it.

Captain Yoon. That's why...

I need you to check if he's angry or calm when you question him.

Pay attention to the subtle changes in his attitude or the way he talks.

Having these answers will help us with our interrogation strategy.

You got it.

To women, he's still a stranger.

No matter how approachable he seems,

women would still be a bit hesitant to get into his car, right?

Right.

And women tend to be more cautious especially at night...

no matter how kind they seem.

If he didn't force them to get in,

it's likely that he made...

these women feel guilty about turning down his kindness.

He made them feel guilty by pretending to be kind?

This jerk is unbelievable.

This guy could skip town for all we know.

- So be careful. - Okay.

We'll be back.

Call us if there's anything.

- Okay. - We'll call you.

- Thank you. - Sure.

I think this is the place.

- I'll check if there's an exit. - Okay.

(Royal Acupressure Massage, Ansan, Gyeonggi Province)

None, right?

Even if he runs, he has to come out here.

Okay. Let's go inside.

(This is a legitimate business.)

- Hello. - Welcome.

Do you have an appointment?

We're from the Wide-Area Investigation Squad...

at Gyeonggi Provincial Police Agency.

Our business isn't illegal.

We're here to see Mr. Woo Ho Sung.

He's here, right?

Why do the police want to see him?

Could you bring him out?

He's with a customer now.

Then we'll wait here.

But your customers will come and go. You're okay with that, right?

Please wait.

Sure.

There.

Is that a wig? I can't see his face clearly.

How do his hands look to you?

You wanted to see me?

Mr. Woo Ho Sung?

Yes. That's me.

Could we step out for a moment? We have some questions.

We can talk here.

Let's do this outside.

No. I'm sorry. My customer is waiting for me inside.

It's fine. Let's talk here.

Where were you on February 23 from 7pm to 10pm?

And what were you doing that day?

Why do you ask?

We need to verify your alibi for a case we're working on.

Did I do something wrong,

Detective Yoon?

On the night of February 23,

a woman in her 20s went missing in Gunpo.

That's the case we're investigating now.

And your vehicle was caught on the security camera...

in the area where the victim was.

My goodness. I didn't know about that.

February 23... Was that Thursday?

It was last Friday.

I see. Friday. Then, on February 23,

my shift must have ended before 5pm.

Right?

Yes. That's correct. Take a look.

(Woo Ho Sung: Kang Dong Su, Kim Ju Hyun, Choi Hye Rim...)

- I see. - I had dinner around here...

with my girlfriend. And then I went home.

And my girlfriend also happens to live in Gunpo.

There are dangerous people in the world.

So I can never let her go alone. I always drop her off.

And I drove her home that night as always.

I don't remember the exact time,

but I was home around 10pm.

Could we get your girlfriend's phone number?

I can't.

Am I obligated by law to give you her number?

I don't want my girlfriend to worry.

Then how about this?

You can check my alibi at the restaurant we went that day.

I made a reservation before going.

Check it yourself.

What if we go there and ask them, but...

Go check first.

If you still can't confirm my alibi,

I'll give you her number then.

Is that all?

I have to get back to work.

Thank you for your cooperation.

You're welcome.

- Thank you. Take care. - You too.

I'm so sorry to keep you waiting.

I'll give you ten extra minutes to make up for it.

(Through the Darkness, Part 2)

(Episode 12)

If we combed through the entire area...

but didn't find additional bodies,

it means he buried them elsewhere.

Like the sixth case,

it must be a place that can't easily be found.

We have to ask him about it when we interview him.

The sixth victim, Yoon Jin Sil,

was abducted in Anyang.

Then Woo Ho Sung buried her...

on his way home to Ansan.

And his place isn't far from the bank where money...

was withdrawn from the account of An Yu Yeon, the seventh victim.

He doesn't live far from where the other victims went missing,

assuming that he was driving.

On top of that, his vehicle was caught on camera,

heading in the same direction that the culprit must've gone.

Woo Ho Sung is our prime suspect.

Woo Ho Sung, that scumbag.

It's possible that he's also committed insurance scams.

I'm Detective Nam from the Gyeonggi Provincial Police Agency.

Did someone named Woo Ho Sung have a reservation here?

Woo Ho Sung? What's his phone number?

That is him.

(Woo Ho Sung)

Yes, Gyeonggi Provincial Police Agency...

It's Detective Yoon.

Hang on. Let me put you on speakerphone.

Go ahead.

Does he have an alibi?

He said he had dinner with his girlfriend that evening.

After that, he drove her home.

Detective Nam went to the restaurant to check.

- What's his attitude like? - He seemed self-assured.

And he's confident.

He also seemed relaxed.

He sounds polite and has good manners,

so I can see the victims letting their guard down easily...

after a few awkward moments upon encountering a stranger.

You haven't checked his car, have you?

We can't search his car without a warrant.

If we aren't careful,

he may try to destroy evidence,

so we'll wait until he gets off work...

and check naturally when he's getting into his vehicle.

How did it go?

He was actually at the restaurant that evening.

He did have a reservation under his name that evening,

and I checked the CCTV footage too.

The woman he was with wasn't the one who was missing.

I think it really was his girlfriend.

- Goodbye. - Bye.

Wait, Ho Sung.

What did the detectives want?

I think there was a misunderstanding about something.

How could they suspect you, of all people?

- It's all cleared up now. - Good.

Darn...

He's clearly different from those who don't have the ability...

to lure their victims or those who launch...

random motiveless attacks.

On top of his expensive car...

and likable face, he has a way with words.

He used all those things...

to find and lure his victims.

He knows that it works.

That's where Woo Ho Sung's confidence comes from.

That's right.

Yes, Wide-Area Investigation Squad...

It's... Hey, hold on.

Go ahead.

We have confirmed his alibi that he had dinner...

with his girlfriend that evening.

Do we know what else he did that night?

Detective Moon at Anyang Station looked into it,

but there's nothing on his call log after 7pm that evening.

We checked all the cameras near his home,

and he got home at around 1am.

He told us that he got home at around 10pm.

We need to go and check.

I wish we could search his house now.

Our priority is to secure concrete evidence.

If we put in a request for a search and seizure warrant now,

the prosecutors will laugh at us.

- It won't be issued. - Chief Park.

We'll wait here until Woo Ho Sung gets off work...

and ask him to voluntarily come into the station.

I'll call you back.

Goodness. Even if we request a warrant now,

we won't get it tonight.

Okay, fine.

I'll speak with Superintendent Heo.

I'm getting a bad feeling.

(Name, Woo Ho Sung)

We need a search and seizure warrant...

for Woo Ho Sung's vehicle and residence.

We must secure evidence as soon as possible.

It's also possible that he committed insurance scams in the past.

Insurance scams? What did he do?

In 2005,

his wife and mother-in-law died in a fire.

The life insurance payouts he got...

were almost 400,000 dollars in total.

What? 400,000 dollars?

He had signed up for various life insurance policies.

But the insurance companies must've deemed it legitimate...

for him to have received the money.

On what grounds are we suspecting him?

Even with Gu Young Chun and Nam Ki Tae,

we found evidence in their homes.

We cannot let this scumbag buy time.

Not even another moment.

He'll destroy all evidence.

And this is...

Song Ha Young's profiling report.

(Profiling Report: Gyeonggi Serial Missing Women Case)

Everyone now knows that he was instrumental...

in tracking down Gu Young Chun and Nam Ki Tae.

You should submit this along with the request.

Okay, I'll speak with Prosecutor Jang.

But I highly doubt that it'll be issued today.

(Pomna Dry Cleaning)

- Should I go pick up some snacks? - I guess you're hungry.

A little.

Go ahead.

- Okay. - Wait, Detective Nam.

(Royal Acupressure Massage)

Mr. Woo Ho Sung!

Do you still have more questions for me?

We believe it'll take a while.

Could we talk...

at the police station?

Are you arresting me now?

Can I see the warrant?

We're asking you to voluntarily come with us.

You may refuse if you don't want to.

But if you refuse,

it will make us more suspicious of you.

We'll continue to keep a close watch on you.

Okay, fine. I'll come in and give a statement.

- Then let's take our car... - The thing is,

I was booked back-to-back today, so I'm very tired now.

But I'm off tomorrow,

so may I visit the station sometime tomorrow morning?

Sure.

Please come...

to the Gyeonggi Provincial Police Agency.

- If you don't come... - I know.

Why wouldn't I be there when I did nothing wrong?

Detective Yoon, should I ask for you when I'm there?

- Yes. - Okay.

I'll see you tomorrow, then.

See you tomorrow.

I saw...

a photo of him with two dogs in his car.

And there was a huge teddy bear in the back seat.

Just as we expected.

Like you said, he's too calm.

- He'll come tomorrow, right? - If he flees, it's him for sure,

so we can put out an APB.

Good work today. Let's call it a night.

(Gyeonggi Provincial Police Agency)

I can't stop thinking that he's the culprit.

He fits every quality of the suspect we presumed.

He's amicable, he has good manners,

he has a good car,

and he also has a luring mechanism in his car.

He's under suspicion of arson and insurance fraud.

We have to be open to the possibility...

that he's proficient in arson.

There's no perp who only commits one crime.

All we need is the warrant.

I'm sure he felt mental pressure.

(Gyeonggi Provincial Police Agency)

(Gyeonggi Provincial Police Agency with the people of Gyeonggi)

(Wide-Area Investigation Squad 1)

(Wide-Area Investigation Squad 1, Team 2)

Yes, Wide-Area Investigation Squad, Gyeonggi Provincial Police Agency.

Yes, may I speak to Detective Yoon Tae Gu?

Who's calling?

I'm the guy who was supposed to meet her today.

If she's in the office, could you put her on?

She's not in the office. If you leave a message,

I'll relay it to her.

Hello?

- Hello? - In that case, I'll call back...

One second, she just came in. I'll put you through right away.

Captain Yoon, it's Woo Ho Sung.

I'm on the line. You've reached Yoon Tae Gu.

Yes, hello. This is Woo Ho Sung.

Mr. Woo Ho Sung.

Do you take a report like this at the Wide-Area Investigation?

Someone set my car on fire.

Sorry?

What do you mean?

Does Wide-Area Investigation Squad take reports like this?

(Gyeonggi Provincial Police Agency)

I thought he was a pretty smart guy, but he wasn't.

He's just feeling guilty.

We got the warrant more quickly thanks to his show.

It's nice.

And the profiling report also played a part.

(Woo Ho Sung's home)

As of this hour, we will begin the search and seizure...

of every article in your house, Woo Ho Sung.

Also, Woo Ho Sung.

You are under emergency arrest for suspicions of abduction.

You should be looking for someone who set my car on fire.

Why are you arresting me?

You have the right to an attorney,

and you have the right to remain silent.

Everything you say will be...

used in extreme, very extreme disadvantage against you in court.

Do you understand?

He's confident, just as I expected.

He knew we'd get suspicious of him for setting his car on fire.

But he still chose to do that to get rid of the evidence.

We pressured him to go talk at the police station,

so he got anxious and made the wrong choice.

I think he wanted to play the victim.

But he was in a hurry,

so he must have resorted to something he was used to.

He forgot that he was under suspicion for arson...

and insurance fraud.

Does he think the police are a joke?

As if we wouldn't have looked over that.

Anyway, I guess he was the type who thinks he's smarter than others.

He tripped over his own feet.

Let's go inside.

You haven't figured out anything.

Why don't you let me go before we start talking?

The fingers that punched in the PIN at the ATM to withdraw money.

It's similar...

to Woo Ho Sung's hand.

Did you see it?

When I went to the massage parlor, and when I cuffed him.

I saw his hands.

Woo Ho Sung is also conscious of that.

It looks like it.

Are other detectives watching me from behind that wall?

You know why you're here, right?

How many of you are there?

Didn't you hear me? I asked you a question.

I'm not sure.

She told you when she cuffed you. Abduction.

Who? Who did I abduct?

You would know better than us.

Do you have evidence?

That's why we arrested you.

Even if you search through my house,

you won't find a thing.

(Scientific Investigations Team)

Did you find anything?

I don't see anything in particular.

He formatted everything.

This is you, isn't it?

(CCTV footage evidence)

What is this?

You used the debit card of a woman who went missing...

and withdrew cash.

Show me...

the evidence that this is me.

Where is that woman?

Who?

This is you.

Where is she?

I really have no idea what you're talking about.

At 2pm on February 24,

tell me where you were.

I slept at home.

Not that. Give me something else.

Something more feasible.

I said I slept at home.

Do you expect me to believe...

that you were asleep in the broad daylight?

In this situation?

What will I do on weekends? I should sleep.

You said you had a girlfriend.

If anything, you would've gone out on a date.

We went out the day before.

I need a day to rest.

It was my day off too.

You don't know who I am, do you?

This is you. I know it is.

Do you have evidence?

If you don't, you have to trust me.

The dead karaoke employee found in that hill was...

probably killed by him too, right?

I believe so.

The dead body had traces of rape too.

We must get him to confess to the sexual assault too.

How did he seem? Is he a little different now?

He did not show any emotional distress.

He seemed rather calm in a startling situation.

It looks like he has an antisocial personality disorder.

Like psychopathy?

- Yes. - Someone extremely self-centered,

lacks a sense of sympathy,

and lacks a guilty conscience.

It looked like he kept two dogs.

It's probably a cover-up.

I'm sure he only used them to lure the victims.

Let's conduct the PCL-R on him later.

He looks like the type who shows aggression selectively.

What do you mean?

People like him have a high level of self-control.

They keep their composure until the moment of their crime.

They won't show their emotions.

But once he begins to attack,

he becomes more brutal and violent than others.

Are you saying he picks and chooses his victims?

You're right.

Gu Young Chun and Nam Ki Tae...

expressed their aggression on many and unspecified persons.

But that man...

only expresses his aggression on the victims he chose.

I think we should be more strategic about our interrogation tactics.

Even if we show him evidence,

he won't confess that easily.

Chief Kook and I will interrogate him.

Two gentlemen are joining me this time.

Are you here to have a conversation with me?

That's right.

What about the other detectives from earlier?

You'll be talking to us for a while.

I told you to get evidence.

I guess it's not going well.

Gosh.

If you wanted to talk to me,

you should have at least brought me some water.

Is that all you need?

We're here to talk to you.

But we're not here to bring you water.

Let us know once you get really thirsty...

during our conversation.

I'll get you some water then.

What are they doing?

Just let them do their thing. They have their own system.

His attitude seems a bit different from before.

Whose attitude?

- Song Ha Young's? - Yes.

Of course, it should be different.

After all, he went through a lot.

This guy is different.

He probably subdued the victims in a matter of seconds...

and clouded their judgment emotionally.

And then, he probably continued his act...

just like he was trying to have...

a power struggle by making me bring water.

I've been sitting here...

and talking to the detectives since I got here.

What else do you want to talk about?

We have our own set of questions.

If you have time for this,

wouldn't it be better spent by looking for evidence outside?

All you're doing is sitting here...

and running your mouth.

We're looking for the evidence.

- So don't worry about it. - All right. If you say so.

It won't take long to find evidence.

Why is that jerk so brazen?

You know that denying their charges shamelessly is their specialty.

According to Chief Kook,

his self-control is very high.

And it looks like he's trying to control his emotions even now.

He asked for water as soon as he saw them...

to test out if he could control them or not.

Does he think he can intimidate them?

How dare he?

Let me ask you a few questions.

Your wife and mother-in-law died...

in a fire a few years ago.

And you only took your son when you escaped from the fire.

When you think about it again, how do you feel?

Why must I think about that now?

I'm just asking how you feel...

or what you're thinking right now.

I don't know...

how the fire has anything to do with this incident.

Why are you bringing up my son?

Your son?

I wonder how your son would feel once he finds out that his dad is...

a serial murderer and rapist.

You see,

he's too young to know anything.

Not yet.

No. Listen.

Nothing has been proven yet.

I really don't follow you.

That's right.

"Not yet."

You received a hefty sum of money...

from the insurance claim.

Are you...

suspecting me right now?

You see, the fire...

started because of the mosquito incense stick.

And the detectives who investigated the case...

couldn't prove anything.

They "couldn't" prove anything?

Right.

They couldn't prove anything...

because there was nothing to prove. Isn't that obvious?

You see, I was trying to survive the fire with my son.

All I did was escape. That's all.

Well,

we didn't say otherwise, did we?

Why did you send your son to your cousin's house?

Once I go to work,

no one's there to look after him.

How old is your son? Is he 11 years old?

Why are you curious about that?

I was just wondering if you knew how old your son was.

Don't be so absurd. Darn...

Don't be rude.

Do you want your son to find out...

that his father is a serial murderer and rapist?

You...

That jerk.

- Why are you doing this to me? - I'm sure you know why.

Let's stop talking about my son.

Why? You don't like it? Is it uncomfortable?

It has nothing to do with this case.

You said you didn't do it.

But you're still ashamed when you think about your son?

Even I'm curious too.

Why is he bringing up the son?

Woo Ho Sung's narcissism.

(Having attachment to oneself)

Serial murderers and rapists...

who commit crimes for pleasure like Woo Ho Sung...

will highly likely show a quality of narcissism.

He did seem to be full of himself.

People tend to develop excessive self-attachment...

as a defense mechanism against pain and despair.

And when they experience an attachment injury,

they feel a sense of humiliation and hopelessness.

So the attachment toward the others gets directed to themselves.

A sense of humiliation and hopelessness?

That can cause narcissism?

They must deny their reality that they can't be loved.

How can we get Woo Ho Sung to talk?

We need to find out the target of his unconditional attachment...

right away.

Unconditional attachment?

It has to be his family. Right?

- His parents or kids. - It can't be his parents.

Having a big trauma like an attachment injury...

must mean that he didn't feel loved by his parents.

Then it has to be his kids. Does he have kids?

He has a son in elementary school.

His cousin is looking after him.

Fine. If not your son, how about your parents?

Why do you keep...

trying to talk about...

my personal life?

That's why we're here.

We analyze criminal behaviors.

(Seoul Metropolitan Police Agency, Kook Young Soo)

You haven't proven...

anything yet.

I really don't understand...

what you're talking about.

How was your relationship with your dad?

My dad?

- He was strict. - Did he hit you too?

No. He never hit me.

Was your family well-off?

Why do you ask?

Do you think...

I had a tough upbringing and grew up in poverty?

This is a standard question.

Gosh. You guys are unbelievable.

You guys are biased against people.

Enough with these ridiculous questions.

Go out there...

and find more evidence.

You just wait. It won't be long.

Gosh. That jerk.

How's the search going?

He has a lot of stuff.

And he especially has a lot of clothes.

That's not an excuse.

We have to bring everything in.

Whenever we tried to provoke him,

he kept asking us if we found any evidence.

He thinks he got rid of all the evidence.

What about his call history?

We used his call history since February...

and tracked his whereabouts with his cell phone...

to check the security footage as we speak.

Gosh. It will take forever.

No news from the NFS, right?

There's too much stuff from his house.

So it will take a long time just to run DNA tests on them.

He set his car on fire for a reason.

He formatted his computer too.

Gosh. We just need some hard evidence to make the arrest.

He seemed experienced in starting a fire.

Serial killers often commit arson too.

Every single one of them started a fire.

We'll have to check a few more things,

but I'm sure he's the culprit.

He said the police "couldn't" prove anything.

Wait. His response is wrong.

He shouldn't say the police couldn't prove it.

He should be arguing that he was innocent.

He killed his wife and mother-in-law?

No humans can do this.

Listen. Are you telling me the only thing we could do right now is...

sit around this table and wait for a call from the NFS?

We have 32 hours left.

You can eat now.

What is this?

You should've asked me first.

I don't eat jjajangmyeon.

It's bad for you.

- What? - I want a proper meal.

With soybean paste soup. Or with cheonggukjang stew.

What? It's bad for you? Unbelievable.

Why are these scumbags...

all so health-conscious?

Who else was like that other than Nam Ki Tae?

Gu Young Chun.

Those scumbags can live long lives in prison.

I'll go feed Woo Ho Sung.

- Okay. - See you in a bit.

- See you. - See you.

Let's resume the interview with him after he's done eating.

- Okay. - Sounds good.

While we're eating, let's think about his MO from his perspective.

- From Woo Ho Sung's perspective? - Yes.

He used his expensive car to lure his victims.

The victims got into his car without suspecting anything.

For that to happen,

there are various conditions that had to be met.

He must've cared a great deal about what he wore.

Yes, they found a ton of clothes at Woo Ho Sung's house.

Clothes that look expensive.

Winter clothes that he must've worn often.

We should check those first. It'll be faster.

He lured his victims inside his vehicle,

so maybe not thick winter jackets.

He most likely wore expensive-looking clothes.

Let's check neutral-colored shirts and jackets first.

Why does the color matter?

Strangers wearing neutral colors tend to seem more trustworthy...

than the ones wearing loud colors.

That's right. This way, we can save time.

Start with clothes that he probably wore often.

Neutral-colored winter shirts and jackets that look expensive.

We ordered you what you wanted to eat,

so it's now your turn to give us the answer we want.

You little punk, you're really something.

I'm getting sleepy now that I've eaten.

All right, let's get this done fast.

That's exactly what we're trying to do now.

You punk.

Are you here to play?

Look, Detective. You arrested me without a warrant...

based on mere suspicion. Am I wrong?

- What? - And you're treating me like dirt.

What will you do if I'm not the culprit?

What if...

I sue you?

What will you do then?

You little punk, you have a knack for getting people riled up.

Chief Park.

- Let go. You piece of... - Chief Park, please.

You'd better confess when you still have the chance to,

or you'll regret it later. You little...

I'm scared.

Darn it.

That scumbag is so confident.

What did the NFS say?

I asked them to check his winter clothes first.

Darn it.

If we find the victims' DNA, it's a done deal.

Let's wait and see.

People like him open up easily to those...

who are either younger than them or have low-level positions.

It's one of the common traits of a narcissist.

Correct.

They want to feel supported and acknowledged.

We shouldn't make him feel inferior.

Then should Detective Nam deal with him without Chief Park?

Let's wait and see.

You killed them.

Take your time and have a look.

Can I get a cup of coffee?

Go ahead.

Looks like he'll confess, right?

He might, or he just felt a sudden pang of guilt.

He did show a reaction at that moment,

but we'll have to wait and see what he does.

He's been denying everything this whole time.

He won't be swayed that easily just because of the victims' photos.

But he's human after all.

Based on his attitude so far, I know he won't confess easily.

And he managed to be cleared of the insurance scam charges.

These women aren't even recognizable.

What do you want me to do with these photos?

That scumbag is clearly a psychopath.

Why did he put down the cup on top of the photo?

Of course, he wasn't going to confess.

"These women aren't even recognizable."

- What is it? - They're photos of one victim.

It's not the owner of the debit card he tried to use to withdraw money.

It's the karaoke bar employee who was found dead in the woods.

He should be under the impression that it's the victim...

we're accusing him of killing,

but he assumed that it'd be more than one person.

What? Then...

It means there is more than one victim.

He's the culprit.

He killed several women.

Hence the reaction.

If he didn't do it,

he'd know nothing about the victim or the location.

So the fact that he said he couldn't recognize them...

is certainly odd.

I found something.

What did you eat?

Pizza.

Here it is.

- Good morning. - Did you work all night?

- Look. - What?

(Han Bong Am, National Forensic Service)

The NFS?

Goodness, they pulled an all-nighter too.

Hey.

Yes, okay.

What is it?

They found a bloodstain on Woo Ho Sung's jacket.

The DNA matches that of the body found in the woods.

Finally, thank goodness. You're dead meat now, you punk.

Also, they found a half-burned lipstick...

in the burned vehicle.

Did they manage to lift DNA?

Not yet. I just wanted to keep you informed.

I'll go in and let them know.

They've faxed the report over already.

- Okay. - Good work, everyone.

What would we have done without you guys?

What is it, Ha Young?

The lipstick.

Maybe it belongs to a victim we don't know about yet.

We need to get a confession out of him.

Goodness.

Finally, we found something.

This is what we've been eagerly waiting for.

(DNA Analysis Report)

The evidence.

It's the victim's DNA...

that we found from your clothes.

(DNA Analysis Report)

We found it.

(Went missing at a bus stop nearby the Chinese restaurant.)

(Specimen 1 and 2 belong to the same person.)

Captain Yoon, the one who just left.

Ask her to come in.

Stop trying to conjure up a trick.

Just confess, you scumbag.

I will confess.

In return,

I want Captain Yoon here.

I'll go get a confession out of him.

Hold on.

I'll go in first.

You?

I want to say something to Woo Ho Sung.

- It'll be quick. - Sure, go ahead.

- Will you be all right? - Yes.

I'll go in myself.

How do you feel?

About what?

You have nowhere to run now.

You're good at finding evidence.

Science is much smarter than you think.

That goes the same for the quality of our investigation.

That perfect crime you want? There's no such thing.

Woo Ho Sung.

- Be smart about it. - About what?

Whether or not you want your son to remember...

you as an unremorseful murderer until the very end.

And this will be the last time we talk.

I'm not scared.

I'm not saying this to scare you.

I mean to tell you that nobody will listen to your story anymore.

I already know that you have multiple victims.

We've acquired all the evidence too.

I thought you weren't here to talk about the case?

- I'm not. - Then let's change the subject.

No. I already have you figured out.

Which is why I'm no longer curious.

Would it be possible...

for me to talk privately with Captain Yoon?

I'll be fine.

Give me your hands.

What is it that you want to say?

I'm sure getting a confession out of someone...

is harder than you detectives think.

Am I right?

It's the same for the confessor too.

Which is why...

I'm torn.

Whether the culprit confesses or not...

is his decision to make.

Then how...

can I get him to decide?

Just give the nuance that you understand him to an extent.

Woo Ho Sung has strong narcissistic tendencies.

If you form a rapport with him,

it'll bring about a change in his emotions.

Don't you think the burden will be lifted...

if you confess?

- Who's burden? - Yours...

and mine too.

Do you really think so?

I'm sure you had a reason...

why you asked for me specifically.

I'm ready...

to listen to whatever it is...

that you have to tell me.

Why did you do it?

Must there always...

be a reason...

why you kill someone?

So...

you didn't have a reason?

Well, if I had to come up with one,

it's because I wanted to kill them.

How many...

did you murder?

We found components...

of another victim's lipstick...

from your car.

It will all be revealed in the end.

That hand.

You tried your best to hide her face.

But unfortunately,

you weren't able to hide your hand.

You've been self-conscious about it all along, right?

I'll come back...

once you are ready to talk to me.

I'll do it.

I will talk.

The suspect confessed that he murdered...

all the women who started going missing from 2006...

around Gyeonggi's southwestern area.

Early this morning in Suwon,

the police found the body of the missing housewife.

They are continuing their search...

- for the other women's bodies... - Is this hair?

Oh, I found it!

- What? - I found something.

Look.

On the day I planned to murder,

I made sure that I executed it.

No matter what.

You're saying you planned for all seven murders?

Of course.

I'm determined...

from the moment I leave the house.

Did you ever fail?

Fail?

I have never failed.

You see,

it's like a promise I make to myself.

I executed it.

One way or another.

The police intensely investigated the suspect...

to find out if he committed additional crimes...

until early this morning.

They will also carry out a crime scene reenactment...

- this morning. - Look over here.

He reenacted...

three out of his seven crimes yesterday.

The bereaved families and residents were enraged once again,

as they watched him...

reenact the crime nonchalantly.

I have always known...

that I was a psychopath.

Why did you think that?

I was watching TV one day.

When I heard the characteristics of a psychopath...

I realized.

That's me in a nutshell.

- Look over here. - Take his hat off. Let me see him!

- My gosh. - That scumbag...

His 2nd crime was by highway 39,

which was his secret burial site.

When the police told him to reenact how he dug the ground,

he was comfortable enough to revise the order.

Saying that he dug the ground after he took the body out of the car.

His calm demeanor as he reenacted the horrible crime...

made the onlookers even more furious.

The bereaved families...

who came later to watch the reenactment...

were crying out, demanding to show his face.

When do you feel the urge to kill?

That is...

a little difficult...

to describe in words.

Hitting on women is a piece of cake.

You see, those girls...

They all liked me.

I'm not sure.

I think it's just you.

Why won't you trust me? It's true.

They all really liked me.

I also think...

you only look like a petty loser.

Sorry for the bad news.

We...

do not...

believe your words.

If they don't listen to me,

then...

I take off...

my necktie and bind their hands and feet.

The investigation headquarter of Gyeonggi Agency stated...

they received the confession from Woo, the suspect who killed...

the female university student who went missing in February,

that he killed seven and buried them until early this year.

Last month, he conducted two psychopathy tests...

and was confirmed as a typical psychopath...

with the score of 27 and 28 respectively.

I will be...

sentenced to death, right?

You should be.

Even after I go up there, I won't find...

my peace.

Did you dream of ending up in paradise?

Goodness, Ji Sook.

Ji Sook, you've returned in such vain.

Let's go.

(Gyeonggi Investigation Headquarter of Serial Missing Women Cases)

Superintendent Heo, a souvenir.

Park Dae Woong! Big bear! You did it!

Thank you.

Good work, everyone.

- Great job. - Great work.

It's sad to see you go.

You don't look too sad.

Tell me about it.

Well, I may not look sad, but I'm glad and sad to see you go.

We'll come back and visit.

It only takes us 50 minutes to get here from Seoul Agency...

I don't expect you to come.

You're the one to talk. I don't expect you to come either.

If we have to meet again, it'll have to be another case...

Goodness, no.

In that case, I'd rather not meet at all.

Let's just keep our memories deep inside, right here.

Captain Yoon, you should also share something.

Let's go now.

- Great work. - Great job.

- Chief Park, let's have some soju. - Let's do that.

Stay healthy, okay?

Yes, be mindful of your health too.

- Bye. - Goodbye.

- Let's go. - Great job.

Why are you moving on a day when I'm free?

Because I moved to a neighborhood you told me to.

I can't move here because there are lots of robberies.

Another place is too dangerous because of burglars.

When I see you, I realize knowing too much can hurt.

Thanks to me, you came to a safe neighborhood.

According to statistics,

this area has 50 percent less crimes compared to other neighborhoods.

And downstairs,

a detective of Wide-Area Investigation Squad lives.

So when will Detective Nam get here?

- Detective Nam? - Yes.

I have your order of gopchang.

- These are all my order? - Yes.

My gosh, this is a lot. All right.

- Goodbye. - Thank you.

Goodbye.

When did you get all these?

- I had to run. - That looks good.

Detective Nam got these?

You can get gopchang to go?

Yes, you can get just about anything to go now.

It's much easier since it's already fully cooked.

It's really good.

- Is it? - Yes, try some.

Let's make a toast first.

Congratulations.

This is how I recharge the energy I lost from moving.

The mood here is perfect.

Let's get together from time to time and have meetings here.

- It'd be nice. - Sounds great.

I got it.

Isn't this the first time we got together outside of work?

- You're right. - Is that so?

- Oh my. - The moon is so pretty.

- Yes, it's huge. - That's very pretty.

- Yes. - Right.

Then let's all make a wish together.

Woo Ju, your drunk habit is making a wish to the moon, right?

- You're right on. - My gosh.

If Woo Ju wants to do that, then let's make a wish.

You make wishes like that?

Then how?

I'm all done.

(March 2007)

Who are you trying to look good for?

Who do you think? The future members of Analysis Team.

- Aren't you excited? - Why should I be?

You should start looking at people other than me.

Good grief.

You should stop digging my nagging.

You need to share your love with these future members.

Let me off right over there.

Forget it. It's a special day, so let's get our hair done.

- Hello. - Yes, hello.

Recently, the vitamin care is received greatly by our customers.

Really?

This is perfect for us.

Then let's do this one.

- Okay. - All right.

- We'll do this. - Sure.

Do you drink a lot?

How did you know?

This is a care routine we recommend to those who drink often...

and have bad blood circulation. For those who are stressed...

and need to be refreshed.

That already feels nice.

- Chief Kook. - Yes?

- Does it feel good? - It feels very refreshing.

Ha Young, you should do it too.

Someone said a person's heart is the most difficult thing to fathom.

But there are those who must do such difficult work.

On top of that, they must fathom the hearts of criminals,

not just any old people.

At times, among countless numbers of criminals,

they must put up a fight to read the minds of serial killers,

the worst evil of them all.

And these people are none other than you.

Some once said an angel is only a hair different from a devil.

Most minds that live an ordinary life,

and the most atrocious minds that commit heinous murders.

Where did they cross their paths?

What made these people so wicked?

Our duty begins with that basic question.

In this chaotic world and dramatic reality,

the only thing that keeps us from becoming evil...

might be in our ability to touch people's hearts.

I hope your duty...

becomes another chance to revisit the preciousness...

and the importance of that ability.

I hope you will...

learn to embrace your own hearts.

Through this duty,

I also had the chance...

to have priceless experiences...

and to realize these important values in life.

(Through the Darkness)

Today, we interviewed the first profiler in Korea,

Captain Song Ha Young of the Behavioral Analysis Team.

Is there anything you would like to say...

before we wrap up the interview?

Well,

we haven't been able to catch the culprit...

of the Daesung Serial Murder Case, a cold case from a long time ago.

And if he's watching the show now,

I would like to say this to him.

Science is making progress day by day.

And there's no perfect crime in this world.

So you'll never get away with this.
