(Jane Doe)

I always had to do this alone.

But the three of you joined me today. Thank you for coming.

Gosh. There's no need to thank us.

I'm sure all the victims were loved when they were born.

But seeing how we couldn't even put a name to these victims...

makes me think life is futile.

So people don't come here.

Thank you for coming today.

These victims faced a bitter end after a life of hard work.

Please help them, so they could be happy over there.

And please give Gu Young Chun a taste of his own medicine.

To someone like Gu Young Chun, that's too generous of a punishment.

I heard that...

Captain Yoon has been working...

day and night to find families of those unidentified victims.

But I didn't think she'd come here.

Captain Yoon...

isn't cutting her hair for the victims.

Why her hair?

She thinks inconveniencing herself...

with long hair is her way of mourning for the victims.

I guess having this sense of guilt...

comes with our job.

(Through the Darkness, Part 2)

(Episode 9)

Learning from the unprecedented case...

which resulted in countless victims,

we see the need to set up...

a comprehensive, government-wide solution...

for the public good and safety.

To prevent from making the same mistake in the future,

we will put together a manual based on Gu Young Chun's case...

for our investigations.

We are setting up the structure, so everyone can be informed.

Moreover,

police officers who committed grave mistakes...

while investigating the serial killer, Gu Young Chun,

were reprimanded to a great extent.

With this momentum,

we will strive to close unsolved cases of violent crimes...

by the end of this year.

And we will do our best...

to keep our people safe.

Good luck.

As you all know, we'll be studying...

Gu Young Chun's case.

The serial killer we recently apprehended.

The public and the higher-ups are criticizing us...

that we didn't catch the killer soon enough.

It's not like we purposely took our time to catch him.

That's right.

He went into hiding and didn't leave any evidence.

What were we supposed to do with him?

I know that it's a hassle.

But we've never had someone like Gu Young Chun.

If we caught Gu Young Chun sooner,

we wouldn't have this many victims.

Was there a problem with the initial investigation?

There was.

All the incidents took place in different districts.

All the initial investigations were done by different stations.

And putting together the information we had,

took a long time.

If we were to reorganize the protocol,

so the Special Crime Squad could investigate initially,

we might be able to lessen the confusion.

Great. What else?

After Gu Young Chun killed...

the wealthy elderly,

he changed his MO.

Despite receiving multiple missing persons reports on our victims,

they were categorized as simple runaway cases.

It's not possible to file adults missing in our system.

There were 11 missing women.

The fact that they were excluded from our investigation...

is a problem.

And we should recognize that...

our existing investigation method didn't work.

Looking for people who might have held a grudge...

and ex-convicts with similar records...

is the first step of our investigation.

How could we ignore that?

I'm not saying we should ignore the system.

With Gu Young Chun's case,

it was confirmed that he didn't have any motive.

And we haven't come across this kind of crime before.

Therefore, we need to accept new investigation methods.

She has a point. I agree with her.

The report from the Behavioral Analysis Team...

was spot on once again.

However, it would be prudent for us...

to also discuss the risk of only relying...

on the behavioral analysis reports when we investigate.

Here's the most ironic factor of this case.

It was figuring out the murder weapon.

Goodness. A hexagon-shaped steel hammer.

Why hadn't we thought of that?

No one uses a steel hammer to kill people.

That's why.

Gu Young Chun chose the steel hammer...

so it'd be easy for him to take down his victims.

In other words, killing was his sole goal.

By controlling his victims, he showed off his power.

And he prepared thoroughly for his killings.

"Prepared?"

As I mentioned earlier, he renovated a hammer...

so the job would be easier.

(Analysis of Gu Young Chun)

And he took a full-body X-ray...

to study where the body should be severed.

Once he started killing,

the degree of desecration gradually escalated.

So the preparations and the act of desecration...

gave him the thrill.

Correct.

So he's not the delusional type who sees hallucinations,

but I'm not sure if he did this with a sense of mission.

I'd say he does exhibit the traits.

He did say he committed the murders to root out social evils.

Using such preposterous logic,

he tried to justify what he did.

Power, influence, and money.

This world where the wealthy get rich illegally,

women live promiscuously,

and civil servants live like bugs.

They all have to be punished!

Gu Young Chun.

He could go on about his "sense of mission."

But essentially, he purposely chose weak targets...

whom he could take down easily.

He's just...

a cowardly loser who's all talk.

I'll build a factory right here.

- Hey! - Look!

Ta-da!

- Look, right here. - Ye Won, Yu Hwa.

It's time to go home. Come on.

- Okay! - Okay!

Ji Hwan, let's go home and eat.

Okay, Mom!

Jun, let's go home.

- Okay. - What are you doing there alone?

Come on.

Don't people like me all have the same story?

An abusive father.

And no one to lean on. I had a miserable childhood.

So do you blame your father?

I bet you have no idea what it's like to live with a dad...

who threatens you with a hammer every time he gets drunk.

I never lived with my father.

He passed away the day I was born.

You're lucky.

Not having one is better than growing up with a father like that.

It's only natural to become all twisted.

You think that's the reason?

Didn't you say you were a criminal behavioral analyst?

Didn't you hear such a childhood...

could cause you to become a serial killer?

He's just trying to justify himself, like a wimp.

I'm home.

It's getting late.

You're still up?

- Good night. - You too.

Come in.

- You're still up? - Yes.

- Here, have some. - Thanks.

I guess I'm getting old. I tossed and turned a little,

and I can't fall asleep anymore.

I made it today. It turned out nicely. Try it.

Okay, thank you. Try to get some sleep.

What's with the booze?

He can't even drink.

(Seoul Metropolitan Police Agency)

You see, we never agree to interview requests,

but he kept pestering us about it.

I didn't know Woo Ju had such a cool friend.

My, what a pretty name. Reporter Choi Yoon Ji.

Here, have some coffee.

- Thank you. - How nice is this?

Thanks to Reporter Choi,

we can sit down and enjoy coffee in the office.

Cheers.

- Cheers. - Cheers.

- It's good. - It is.

As I mentioned last time... No pictures, please.

Oh, this.

It's like a soldier's weapon on the battlefield.

I always have it with me wherever I go.

I won't be taking any pictures today.

It'll just be a story that introduces the team.

My gosh, why am I nervous?

I feel like I'm being interrogated.

- Relax. It'll be like a chat. - Okay, sounds good.

Here's what I was most curious about.

Common motives for murder...

include money, lust, hatred,

and revenge, right?

That's right.

However, Gu Young Chun is a serial murderer...

who completely deviates from that.

What do you think is the reason behind...

such motiveless murders?

Here's what I think.

Feelings of social isolation...

have been on the rise, and these brutal crimes...

are manifestations of blind hatred resulting from that.

- Blind hatred? - Yes.

Profilers aren't psychics.

We analyze the psychological and behavioral patterns...

of culprits and assist in investigations...

so they can be caught as soon as possible.

We use accumulated data to analyze such patterns.

Interviewing other convicts is a part of that.

There are always traces left at crime scenes.

And every murderer leaves a trail.

Their behaviors...

show us what their motives are and what they're trying to achieve.

That's right. The Forensics Squad...

finds evidence at the scenes.

And we, profilers, analyze the clues and circumstantial evidence...

based on our observations of the scenes.

(Fact Today)

We're analyzing the incidents in southwestern Seoul at the moment.

I want to say this to the culprit who will probably read this.

"We'll catch you soon."

I do hope you catch the culprit soon.

I can tell you this one thing for sure.

There's no such thing as a perfect crime.

Way to go, Yoon Ji.

I always knew that you were so capable.

I'm so proud of you.

This article will be a hit.

I need to focus.

Oh, right. Sorry.

You know how important this article is.

Fix this typo, Yoon Ji.

The Behavioral Analysis Team will become the stepping stone...

to the much-needed reform of police investigations.

Inspector Song Ha Young?

He's not here. You called the Special Crime Squad.

Hello?

May I speak to Inspector Song?

- Who? - Inspector Song Ha Young.

Call the Behavioral Analysis Team.

(Fact Today)

"The Behavioral Analysis Team will become the stepping stone..."

"to the much needed reform of police investigations."

He's not here at the moment. Okay.

Goodness gracious.

I keep getting calls from people I don't even know.

I didn't know it'd go viral like this.

I didn't know so many people would read Yoon Ji's article.

The media has such a wide reach.

Maybe it's all thanks to us, the Behavioral Analysis Team.

He has stepped out of the office.

I'm afraid I can't give you his number.

Okay.

This will go on for a while.

(Behavioral Analysis Team at Seoul Metropolitan Police Agency)

(By Reporter Choi Yoon Ji)

Choi Yoon Ji is smart.

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

(It's that career you saw in "The Silence of the Lambs.")

Hey, I don't even want to see Song Ha Young.

Must you do this to me knowing I got demoted?

Stop bothering me already.

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

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

(Behavioral Analysis Team)

Hey, you're early.

What's that?

(Inspector Song Ha Young, Criminal Profiler)

Im Moo Sik, this jerk.

We clearly said, no photos.

It's for the better.

I'm glad the media is interested.

We've been talking about...

expanding the Forensics Squad into Scientific Investigations Division.

I'm guessing the higher-ups are starting to understand our language.

We were literally beaten.

And I hope...

Scientific Investigations Division can be led...

by you, Captain Kook.

- Me? - Yes.

What are you talking about?

The Analysis Team keeps me busy enough.

I've been trying to convince those people up above,

so don't just say no, and give it a thought first.

There is nothing to think about.

I don't need that position.

All I need is the Analysis Team.

On top of that, we only have three people.

So if the captain disappears,

how do you call that an expansion? It's a reduction.

Goodness, what do you think, Inspector Song?

Yes, you can do it instead.

I'll do whatever Captain Kook decides.

But I agree he should be the captain of Scientific Investigations.

- See? I told you. - Why?

- It's just you. - I have enough work.

- Stop complaining. - Hey, Detective Nam. What is it?

Forget that.

- Gocheong-dong? - Deal with Im Moo Sik.

That's Guro-gu.

Why are you going alone? What about Captain Yoon?

- He never listens. - Oh, she's at the prosecution?

Okay. You should go.

No, one second.

Analysis Team should go with him.

- Go where? - Gocheong-dong.

I'll send them over. Okay.

Why?

He thinks it's related to the Southwestern Case.

(Gocheong-dong, Guro-gu)

- Is this it? - Yes.

The end of April.

The weapon was a kitchen knife.

The victim was murdered around 2:30am in front of the door,

also with the key in the keyhole.

Aren't you coming in?

We start from the outside.

We have to check the environment...

and the structure of the building before we go in.

That way, we can infer the reason why the perp chose this place.

We think like the culprit...

and try to guess their movement and follow that.

Once we go through this process,

we'll reach the murder scene in the end.

So that you can imagine...

where the culprit went and ended up running into the victim?

- That's right. - I see.

Anyway, how did you receive a report on Guro-gu's case?

They asked for cooperation,

so police stations nearby are out here checking similar cases.

We concluded that...

the Imyeong-dong Case wasn't done by Gu Young Chun.

Also, everyone has their eyes on this case...

since the Pureumae Park Case, so they're cooperative.

I see.

(Yongcheon Apartment)

Compared to the cases from Geumcheon or Dongjak Stations,

- the air is a bit different. - It is.

How is it different?

Unlike other apartments, this one isn't near any other buildings.

This one is completely detached.

- Let's go inside. - Shall we?

The key was in the keyhole.

And her bag and wallet were spread out in front of her.

- And the money was still in there? - Yes.

Did he wait for the victim to go into the house?

What if she had family at home?

Then his crime would've been exposed.

Would he risk such danger?

He's the type who shows his face, so that could be possible,

although I don't understand it.

I think there might be another reason.

Let's go back, then.

First off, he probably chased up the stairs after her.

The victim puts the key in. She's about to go inside...

You startled me.

I think he hesitated until the moment she went in.

The culprit seems aggressive, but he doesn't seem to be bold.

He's rather timid.

Sounds great. Just as you said,

he could have hesitated until the very last minute,

then found enough courage in that last moment.

Then what about showing himself...

under the bright light and stuff?

He wasn't showing them his face.

It's the other way around.

He wanted to see the victim.

He wanted to check the victim's face before he kills a stranger?

The moment he attacked them,

he was looking...

at the victim's facial expression.

- Hey, Woo Ju. - You're here.

This is it?

- Please print these. - Yes, sir.

- Did you eat dinner? - Yes, I did.

All right, then. Let's start with...

Let's hurry.

- Let's see... - Hello.

Oh, hello.

Take a look at this record. It says right here...

In that case, this is...

(Prosecutor's Oath)

I'll have to stay here until late at night.

Report back to me every now and then if anything comes up.

Sinheung 2-dong and Gocheong-dong.

Two victims both died in front of the door,

with their key in the keyhole.

I believe this shows the culprit hesitated...

until the moment the victim went into the house.

If he's a timid guy,

that explains why these victims were...

attacked in front of their house.

Right.

Gocheong-dong Case broke out in April,

so it must be before Pureumae Park Case.

Yes, there were too many cases reported to Dongjak Station,

so they recognized...

the Pureumae Park Case first in the same jurisdiction.

That means the culprit began to use a kitchen knife...

starting with Gocheong-dong.

In that case, the culprit changed the weapon...

to make sure he kills the victims, just as we predicted, right?

That's the highest possibility.

Other than the Imyeong-dong case,

everything else only lasted in severe injuries.

These results probably made the culprit more anxious.

And he has evolved.

He might have studied the ways just as Gu Young Chun did.

He studied?

These people study a lot to kill.

That's why he made the steel hammer himself.

These psychos are beyond my imagination.

Gocheong-dong is in Guro-gu too.

The cases mostly broke out in the southwestern area.

Do you really think he's behind the Imyeong-dong case?

We thought about it for a long time.

But look at the subway line. Line One.

Like this.

Most of these areas are near Subway Line One.

Sometimes Line Two.

We thought the area was within the culprit's usual reach.

He might be someone who lives around Subway Line One.

Gu Young Chun went back and forth...

between the south and the north of the river to confuse us.

He also claimed that he took the subway,

but this man doesn't look that meticulous.

(Hanyung, Line One)

The locations for cases in the southwestern area are...

all in different jurisdictions,

but they are all within walking distance.

Precisely.

Also, he does not look for his victims before he acts.

He went out at dawn or late at night,

when there aren't many people to spot women who travel alone,

then followed them and attacked them ruthlessly.

Man.

So we're looking for a psycho who's in the southwestern area,

walking around with a knife.

You're right. That's him.

What if he fails to find a victim?

I'm sure there are many more days when he fails.

If such days continue...

As you can see, he changed his weapon.

Then he'll change his MO, just as Gu Young Chun did.

He changed his weapon...

from a camping knife to a kitchen knife.

What will it be next?

(Profiling Report)

Will it be a steel hammer, just like Gu Young Chun?

(Gocheong-dong Murder Case)

(Date and Time, Location)

He studied his crimes,

and his MO evolved.

He's timid.

He hides in an alley and looks for a victim.

But he's aggressive enough to watch his victim in pain...

as he attacks them.

What will it be next?

Where will he be?

How far will he go?

Inspector Song?

You're here.

I thought you were staying at the prosecution all night.

We got done much faster than I expected, so I stopped by.

I read the case file on the Gocheong-dong Case.

And this is the profile report.

I'll share this with the Special Crime Squad tomorrow.

"The culprit is introverted because he lacks the ability..."

"to make social connections."

I remember that you made a similar analysis...

with Cho Hyun Gil a few years ago.

Is that correct?

Yes.

Back then, you said that he chose young kids because...

they wouldn't be repelled by him and then sexually assaulted them.

That was the reason you gave us to support your claim.

Then what about this guy?

It's similar.

I concluded that he didn't have the social skills...

or the guts to lure his victims.

That sounds plausible.

After all, he mostly followed his victims at the scene.

Right.

But what worries me is that...

his MO is progressing.

It's progressing.

We need to increase the range of similar cases we investigate.

Right. But...

there seem to be a lot of hypotheticals again.

It will be difficult to make them understand why...

and how many more cases...

we should include in our investigation.

If we hesitate and delay implementing these changes,

there will be more victims.

The Special Crime Squad wants to catch the culprit...

as soon as possible too.

Are you still drawing a line between our teams...

even when innocent people are dying?

That's not what I was doing.

It's likely that he will move on...

to breaking and entering or arson.

- Arson? - Serial killers enjoy...

setting things on fire.

It's an easy way to satisfy their urges.

And one more thing.

Being timid during the act...

is his unique factor.

(Gocheong-dong Murder Case)

(Date and Time, Location)

The murder case took place in April...

in a low-rise apartment in Gocheong-dong.

The victim was attacked...

in front of the door with the key in the keyhole.

And this incident shares a lot of similar factors with the incident...

that took place in another low-rise apartment...

in Sinheung 2-dong last February.

We noticed many factors which indicated that...

these incidents were carried out...

by the culprit of the Southwestern Serial Murder Case.

(Scientific Investigations Team)

Inspector Song is focusing on the progression of his crimes.

He speculated the culprit might break in and commit arson.

Well, I get why the culprit might start breaking into houses.

But arson too?

Right.

Gu Young Chun only set the house on fire to remove his traces.

I'm not so sure if it's the right call...

to put serial killers and arsonists in the same group.

He said serial killers are used to committing arson.

But still. This is too big of a range for us to investigate.

Right.

Then we have to investigate all the violent crimes we have.

(The visions and goals of the administration)

(Promotional strategies)

This is Yoon Tae Gu of Seoul Metropolitan Police Agency.

Please share any break-in and arson cases with us.

But only when the culprit doesn't take any valuables or money.

Hold on.

Please include cases as long as the amount isn't big.

What are these?

He keeps changing his weapon.

He used a kitchen knife after a camping knife.

I'm sure he'll change his weapon again.

Put them away after you study them.

They are just tools.

But they look creepy in this office.

What's wrong? What was that?

What are you doing?

- To become him. - To become him?

I will become the culprit.

(Seoul Metropolitan Police Agency)

The police decided to reform their investigative system...

in order to proactively handle criminal cases...

that target random people...

just like the recent serial murder case.

The police agency set up an investigation support center...

to prepare for the violent crimes...

and decided to reform the Special Crime Squads...

into Wide-Area Investigation Squads.

On a day like today,

you ought to drink beer and soju together, Gil Pyo.

- Gosh. - Here you go.

- That's enough. - What are you talking about? Here.

- Okay. Cheers. - All right.

- Good job. - Okay.

(Tripe Story)

- The tripe here is great. - Goodness.

Superintendent Heo Gil Pyo of Gyeonggi Provincial Police Agency.

Too bad that you won't get to see me now.

What are you talking about?

I'm finally going to have good bowel movements. I feel great.

When you go to Gyeonggi Provincial Police Agency, shave your chin.

Try to look clean.

You can get here in 50 minutes from Gyeonggi Province.

Doesn't it mean you can visit us when you want to?

No, it takes longer with the traffic jam.

There are a lot more cars after the World Cup.

The outer ring road is all set up now.

Once you get transferred, it's not as easy as it sounds.

You have to experience it to know.

Please don't forget us when you transfer.

- Of course, not. - Right.

Exactly. Gil Pyo won't forget us.

Good work.

By the way, you lost a lot of weight, Inspector Song.

- Me? - Yes.

I don't know. I just don't have an appetite these days.

- Here. Eat a lot. - That's not good.

You and Young Soo will be so busy that you wished you had two bodies.

I don't think you're in any position to worry about others.

You know what? I'm sure Superintendent Heo...

and Captain Kook will do a fine job.

He's Chief Kook now.

Gosh. I don't like changes.

Just keep calling me Captain Kook.

How could we, Chief Kook?

Goodness. It sounds like Chief Cook. Cook as in chef.

What a title!

I'll get going first.

- Are you going to the scene? - Yes.

Yes. If you have work to do, don't feel bad. You can go.

- Let me go with you. - No. I'll go alone. Stay here.

- I'm sorry. Please excuse me. - Sure.

Bye.

Who are you? What are you doing here?

I'm sorry. I'm from the police.

We talked about a strange man...

walking around our building at night during the resident meeting.

Can't you be considerate of people who actually live here?

- I'm sorry. - Don't just stand there.

If you're done, get out of here.

Okay.

If you're sorry, you wouldn't be doing this.

So what if you're a cop?

Beat it!

(Yongcheon Apartment)

- Bye. - Bye.

- Goodbye. - See you.

- Sir, there's a taxi. - There's a taxi.

- The taxi... - Get me a taxi.

- Yeonhui-dong! - Over here. Take the taxi.

- Bye. - Chief Kook.

Bye. See you tomorrow.

(Song Ha Young)

Who is it?

Ma'am, it's Kook Young Soo.

Sir.

Hey.

You're just getting home.

Your mother should go to sleep soon.

So I'll leave after I nag you for a bit.

- Please sit. - Okay.

Goodness.

It is good to be focused on work,

but it is important to separate work from home.

I know, I should.

But it's not easy.

I live alone, so it's a different story.

But you live with your mother.

If you leave these case files wide open on your desk...

She'll be worried.

She has a good understanding of what I do.

That is different...

from how concerned she must be as a mother.

You need to learn to pay attention to how the people around you...

must be feeling.

Thank you for the advice...

and also for your nagging.

But must you do this at this time of night?

Good point.

I should get going before you kick me out.

- Captain Kook. - Tidy up a little.

I'm off.

I'll try.

Of course, you should.

We're in this for the long haul.

Right.

- Bye. - Bye.

- Get home safely. - Will do.

Thirteen murders that took place in the metropolitan area...

in the past two years still remain unsolved.

At this rate, they'll most likely...

become cold cases where the killers remain uncaught.

The murders of the three women in southwestern Seoul,

which began in April, still remain unsolved.

The police have announced...

that they would investigate missing person cases,

but the decline of public trust in the police is evident.

Since there is no evidence of sexual assault,

the police are investigating the incidents...

as simple mugging cases or attacks caused by resentment.

It seems that the culprit usually uses Subway Line One.

Most of the Southwestern Cases...

took place late at night or after midnight.

If he fails to find a target...

He attacks right before his victims enter their homes knowing the risk,

because he's obsessed with murder.

- Why are you getting home so late? - You're still up?

I was so worried. Come on in.

So he won't give up...

until his day is over.

(Mibun-dong, Gunpo)

Would you like a bottle of juice?

Ma'am.

Anybody around? There's a woman collapsed on the ground.

Anybody around?

Hello, you've reached...

the Behavioral Analysis Team at Seoul Metropolitan Police Agency.

Inspector Song Ha Young?

What is it about?

Gunpo Police Station?

I see. Fax us the details. I'll pass it along.

Gunpo? Is it about a new case?

Yes, they think...

it could be a serial case. They want us to take a look.

(Facial Composite)

The victims in both cases...

were stabbed in the stomach with the same weapon.

Near Geumyang Station and Gunpo Station,

both on Subway Line One.

What kind of weapon?

The pathologist believes that it was a fruit knife.

Those blades are less than 10cm long.

Just like camping knives.

And no money or valuables were stolen?

You all need to see this.

(Facial Composite)

Looks a lot like the culprit in the Southwestern Cases.

(Facial Composite)

The cases in Gunpo...

took place at around 6am and 5:40am.

There was a huge risk of being seen,

but he took the risk regardless.

A while ago, you mentioned something about timid aggression.

Could that have something to do with this?

Yes. He's timid, so he prefers to do it...

when people aren't out and around, but he did this in the morning.

It shows us that he's aggressive and is willing to take a risk...

just to kill.

He was probably on his way home...

after failing to find a suitable victim...

when he ran into the juice lady near his residence.

In other words, he was determined to kill.

Yes, at all costs.

Why don't you call Gil Pyo and ask him...

to share the reports on the cases that occurred in Gyeonggi Province?

Then we'd be able to find more similar cases.

That's no problem at all,

but there will be a ton of reports.

We'll start with the ones that took place within the year.

We'll give it a shot.

(Gyeonggi Provincial Police Agency)

(Arson, Breaking and Entering)

(Printing)

Put it here.

Have you checked it yet?

Oh, boy.

- Here. - Don't forget that report.

It's never-ending.

Anyang.

Here, the northern district. I'll put these here.

Do we have the ones from the southern district too?

(Daily Case Report)

Let's break for lunch.

- Sounds good. - Let's go.

Let's go eat something.

Oh, you guys go ahead. I'm not hungry.

My goodness.

(Daily Case Report)

- Ha Young. - Yes?

What's that?

Oh, this. It's from the Forensics Squad.

Why are you putting it in your drawer?

I'll return it later with the other things.

- Hand it over. - Sorry?

Hand it over. I'll go return it.

- I'll return it later. - Song Ha Young!

This is not the first time we received calls...

about a suspicious man roaming the neighborhood.

My apologies. This won't ever happen again.

Please be more cautious from now on.

Of course. I'm sorry.

Thank you for your hard work. We'll get going then.

- Thank you, I know you're busy. - Yes, I'll leave you to it then.

Okay.

- Take care. - Thanks, you too.

Let's get something to drink.

For the first time,

I'm starting to wonder if what I did was right.

I was merely trying...

to put myself into the culprit's shoes.

It's better not to know if you have to wield a weapon just like them.

I was not trying to harm anyone.

But you were a threat.

I know it is important to think in their shoes.

But this method is too dangerous.

Look at you.

Just take a look at yourself right now.

Looking into those punks' minds? It's all good.

But before that...

Take care of yourself first. Please.

Whenever I think about those punks strutting down the streets...

and killing innocent people...

At night these days,

I'm reminded of the victims' faces.

So out of all the methods, this is the one you chose?

Do you have to kill someone too to catch those punks?

You seem very unstable right now.

I just want to catch them as quickly as possible. That's it.

I feel like that responsibility...

is weighing you down too much.

I also feel like you have gotten more impatient...

since your interview with Gu Young Chun.

But Ha Young.

You have endured everything so well up until now.

To the point that it's shocking.

But we're in for a long haul.

How about you take a few days off?

- I'll take care of myself. - Ha Young.

I'm sorry for the trouble I caused.

This will never happen again. Let's go.

So out of all the methods, this is the one you chose?

Do you have to kill someone too to catch those punks?

With various crimes happening one after the other...

anxiety is starting to spread amongst the people.

The people think that the police are unreliable.

Hello?

Can you come pick me up later?

In the case of one town in Seoul, residents have been taking turns...

patrolling the dark and desolate streets at night.

Only the people's troubles and burdens have increased...

due to our society's troubling times and unstable public order.

(March, 2006)

(Mogu-dong, Gwanak-gu)

A fire broke out...

at a house in Mogu-dong, Gwanak-gu at dawn today.

The mother and father who slept in the master bedroom evacuated.

But the daughter who was sleeping in the other room was found dead.

The police are taking note of the fact that there are traces...

of the victim being bludgeoned in the head multiple times.

They've started investigating with the possibility...

that the culprit started the fire to cover up the murder.

The footsteps from the balcony headed for the small room first.

(Crime scene stepping plates)

He wasn't after their valuables.

Right, since cash or expensive jewelry...

are usually kept in the master bedroom.

- You're here. - Hello.

I think it started from here.

He stood here and hesitated.

What was he hesitating about?

If it were me...

Hey, what do you mean, "If it were me?"

If I was the culprit,

I would have headed towards the small room first.

Timid aggression.

It's the signature of the culprit from the Southwestern Case.

Do you think it's the same guy with the Southwestern Case?

Yes.

(Crime scene stepping plates)

Usually, there are children...

in the smaller rooms.

Yes, that's true.

Ha Young.

Just as Inspector Song speculated...

he broke in and it led to arson.

Chief Kook.

I received a call from Gwanak Police Station asking for your team.

- They called you first? - Yes, they did.

Those guys are at a loss,

so I think they are curious.

Go with Inspector Song...

and brief them on the profiling analysis you made.

Gosh, I wonder if they'll even listen to us.

I'm not sure.

They may not be too welcoming of it since it's their first time.

But I'm sure the two of you will do fine.

- Okay, we'll do our best. - All right.

(Seoul Gwanak Police Station)

We speculate that the culprit for Mogu-dong and Southwestern Case...

is the same guy.

And he used many different weapons and used them repeatedly.

On top of that, he's used to walking and running.

He walked to the murder scenes, so he's probably in sneakers.

He probably hid his weapon somewhere.

How do you know?

It depends on how you attack someone,

but weapons that can kill are usually big and sharp,

so they're noticeable.

It would've been tough for him to carry it around.

However, there is a high possibility that he carries around...

small weapons like a camping knife.

Also, his murder attempts weren't successful every time,

so do look into insignificant cases of violence...

that break out at night.

Who does he think he is to give us a sermon? Isn't that right?

Right.

He was in the newspaper too, so let's hear him out first.

The culprit is probably around 35 years old.

Man, is he a shaman or what?

- Exactly. - Wild guesses?

Why is he in mid-30s?

Behavioral Analysis Team...

turned over 1,000 violent crimes...

and cases of violence into data.

Hey, wait.

Over 1,000 cases?

And we've interviewed over 200 criminals.

- What? - Over 200?

We used this data and put together the cases of random killings,

and most of the culprits were...

between 33 to 37 years old.

So he isn't just a shaman, after all.

In order for his anger to blow up,

he should at least be in his early 30s...

to have enough social provocation.

Don't people in their 20s blow up in anger more often?

- Young people's vigor is scarier. - Right.

- You're right. - Younger people.

People in their 20s tend to be more impulsive with their emotions.

However, no, perhaps that's why their crimes are...

mostly random, without a plan or bringing changes into their MO.

- What? - He has a point.

The said culprit lacks social skills.

So if you talk to him,

there is a high possibility that he'll avoid your eyes.

- Get it out there. - Yes, go out in a hurry.

- Do we look into those cases? - Yes.

Look into all violent cases for culprits in their 30s.

Excuse me.

- Excuse me, sir. - What is it?

We're from Gwanak Police Station.

I'm sorry to ask, but could you take your glasses off?

We're from Gwanak Police Station.

Are you Mr. Kim In Kyu, 35 years old?

That's me.

By any chance, have you seen a man who looks like this around here?

Have you seen a man who looks like this around here?

I haven't.

(Sinheung 6-dong, Yeongdeungpo-gu)

What? Who are you?

What?

Hey, let go of me!

You jerk!

Over here.

We're from Sinheung Substation. Who's the reporter?

It was me.

This jerk. He's a robber.

My son almost died.

What kind of an idiot carries such a big and heavy weapon...

- to rob someone? - Tell me about it.

Isn't it too heavy for you to carry?

You should go out and get a job.

People get paid a lot for day labor these days.

Exactly.

(Scientific Investigations Division Behavioral Analysis Team)

Inspector Song.

What is this?

(Suspect Information: Nam Ki Tae, 35, male, 5 previous convictions)

From Yeongdeungpo Police Station.

(Spotted relevance with the Southwestern Serial Murder Case)

(Yeongdeungpo Police Station)

- What are you talking about? - We caught the man!

- That's nonsense! - What are you trying to say?

- Hello, one second. - We got this guy first.

All right, now.

- Everyone, look here. - Superintendent Baek.

I'm Superintendent Baek Jun Sik of Seoul Agency.

- Yes. - Hello.

I understand that you are all dying to interrogate this guy.

But first, this profiler, Inspector Song Ha Young will...

have a talk with the suspect.

After that, we'll hear out what Inspector Song has to say.

And then we'll interrogate him.

- But he's not the one who... - I get it. I know.

We know that Yeongdeungpo got him first.

We'll give you enough time in order.

What?

Do you know me?

You're the guy who caught him.

He's the one we've been looking for.

(Psychological Analysis for Gu Young Chun)

(Childhood, Crime Preparation)

I have a question.

The analysis results on his childhood...

and the serial killer's emotional and cognitive thinking are...

all shared by criminals,

as we can see on our interview reports.

Then if we put these characteristics together,

can we find the possibility someone might become a monster later on?

That's the most troubling area.

For example, arson and animal abuse...

that are spotted after a certain age are...

also considered as signs of a potential serial killer.

Gu Young Chun's childhood does match with the theory,

but I'm not sure if we should include this.

You're right.

He experienced a lack of support as a child,

but not everyone like him turns into a criminal.

Some people end up becoming stronger.

I went through a lot because we were dirt-poor.

But I grew up into a detective, not a criminal.

And I grew up with a single mother.

Do you think monsters are born...

or made?

I'm not sure.

If such lives are already decided from the moment they're born,

it just seems too unfair and cruel.

Life has always been unfair.

At times, when I am sitting there with criminals,

I begin to want to believe that people are born evil.

"He must have always been that evil. There's no way he was once good."

And if such people are made,

our world will seem hopeless.

But if the world is responsible for creating monsters,

it should share the responsibility too.

Right.

I wonder what kind of environment they grew up in...

to become such monsters.

I'm leaning toward believing that people are born evil,

but a bigger part of me wants to believe...

that people are inherently good.

"One's perception of others determines..."

"whether people are inherently good or evil."

That's what I heard.

Then it means I haven't given up hopes...

on people, right?

What about you?

I don't think what we are born with matters.

It's important to remember...

that these decisions were made by us, not by other people.

Right. Whether or not our world has monsters,

it's important to remember that anyone can become one.

Gosh. It's been four years since our team was formed.

A part of me is concerned too.

Don't go in too deep.

If you go in too deep,

you might fall into that hole.

I'm not here to interrogate you.

I just wanted to talk to you.

We didn't find any luminol reaction.

We need to find the victim's DNA.

We won't be forced to release him, right?

This jerk. He's no joke.

Nam Ki Tae gave his all to his murders too.

Do you want to hear my story?

I couldn't talk to anyone about this. I was so frustrated.

People who are fighting monsters must be careful, so they don't...

turn into monsters.

You don't have to shoulder all the burden on your own.

If I was going to run away, I wouldn't have started.
