Episode 10

Huh?

What is this?

Unidentified Caller

Unidentified Caller

Hello?

Stay in your car and listen.

Who are you?

I know who killed Park Jae Min.

Um... Wow, is that so?

If you want to know who the culprit is, do as I say.

Are you not the culprit?

How are you going to prove this isn't some kind of prank?

If I had time to prove things like that, I would have poked out your eyeballs and cut off your tongue first.

If you want to know who the criminal is, take down that stupid YouTube video,

and acknowledge that you were wrong. If you do that, I'll call you back.

Hell- Hello? Hello?

Unidentified Caller

What the hell? Is this real?

What's this? In case of fire, destroy this wall?

Huh?

What?

What is this?

Oh, right. They put a fake wall in the veranda so you can escape to your neighbor's apartment in case of a fire.

They came in through the neighbor...

Check the CCTV and see if anyone entering or leaving the neighborhood's home before and after the incident.

There will be lots of people who came here, because it was a model home.

Okay.

Great Detective
Tak Won's Office

100 Year Life
Good Life

I look good.

My jawline is great.

Team Bulldog: Off-duty Investigation

Great Detective, Tak Won's Office. A different scale detective with...

a dog-like ability to handle business. Woof Woof?

What do you mean?

Goodness...

A different scale detective with a thunder-like ability to handle business.

Dammit. The 'bun' character is missing.
(T/N - thunder is 'bun gae' and dog is 'gae')

But looking at the subcontractors, I think people will ask you to commit murder, not come to you with cases of incidents.

'Bun'

So you're saying someone left this phone in your car?

Have you checked the name on the phone and your dash cam?

I looked into the phone but of course it was a cloned phone,

and I sold my dash cam ages ago, because I was running low on cash.

Oh no. Years are forming at news of your poverty.

Do you have no interest of joining me in my work?

Nope. Please just help me with generosity as great as Einstein's.

You mean Schiweitzer, not Einstein.

This looks like the 10th locked-room case which occurred in 2012.

It's the same person, and the knot is tied the same way.

Oh? Wa-wait a minute.

Does that mean I really had a phone call with the locked-room serial killer?

There's a high chance that's true. What did he say to you?

I know who killed Park Jae Min. If you want to know the culprit, do as I say.

That's the basics of a deal. Take and give.

It's it backwards? Give and take.

No, no. Since it's more advantageous to get what you want first.

So what did he tell you to do?

He told me to first take down the YouTube Live video that PD Hong put up.

- Oh, the one that featured Dr. Pi, who isn't as attractive as me?
- Yes, Detective Durian.

He also told us to post a video saying that we were wrong.

I guess his pride must have taken a hit.

A character trait of serial killers

is an inability to contain their anger when people don't recognize or misinterpret their murders.

Then what should we do? We can try to do something about the posted video,

but in the perspective of a broadcasting station, an apology video

is not something I can decide on myself.

Well, there are always two options.

Do as the man says,

and become an outstanding PD that conducted the first interview in history with the serial killer himself,

or just ignore him and continue living as one of many PD's in this world.

What if this is all just a prank?

Don't worry about that.

We have 100 Year's Good Life. I'll help you.

Shut up. Even if I become unemployed, I wouldn't go there.

Why did he have to live next to the model home? Everyone's fingerprints and DNA is mixed in the apartment complex.

I'm sure he used that to his advantage.

Why does everyone already look so down?

- What is this?
- Share it.

Everyone, drink one and recharge your sugar levels.

Thank you!

Amatta, did you find anything in the CCTV's?

Yes, look at this.

Doesn't this person look like the culprit?

So he went in pretending to be looking around the apartment,

then used the fake wall in the veranda to enter Park Jae Min's home and kill him,

then slipped out after everyone else left.

Wow... I just got the chills.

The materials he used for his crime must be in that suitcase, since he left the body as is.

If we can just find that suitcase, then we would have overflowing amounts of evidence.

We can't tell at all who it is because he's wearing a hat and a mask.

Well, since we have the CCTV footage now,

conduct a witness investigation on all the people who entered and left the apartment.

Check all of their alibi's again.

Okay.

Can you see something? It's the same screen.

I know. I can see it with my eyes.

Really? Who is it?

- Hey Amatta.
- Yes?

Let's be sneaky and use a search warrant.

Huh?
[Geumpyeong Police Station]

A search warrant for a home?

Even though 10 years as passed, I can't even use a search warrant as I please.

I opened the door for you since you brought a search warrant, but what's going on?

The old couple are very proper, law-abiding people.

Well, it'll be over soon, so don't worry. Thank you.

Why is she so suspicious? Hey, look around carefully okay?

Okay.

Huh? Hey, long time no see! How have you been?

- L-Leave right now.
- What's wrong?

- Leave! Leave!
- Do you need to pee again?

Why are you being like this? Let go! Let's just talk.

Goodness, I can't flip you over. So heavy.

Ouch!

Let's just talk.

I'm looking for a suit case, but I have a feeling it'll be here.

I found it!

He found it.

It's identical to the one that's in the CCTV footage.

Wow, this is irrefutable evidence.

Let's take him first and conduct an investigation.

No. If we catch him without conclusive evidence and then have to let him go again,

it's hard to re-arrest him.

Goodness. I can't repeat the mistake I made 10 years ago.

Ask the forensics team to process this immediately.

- Okay.
- Goodness...

Long time no see. I knew you would come after I got Deok Su's call.

I heard you took a suitcase.

Are you going to arrest me again?

Well, I wonder. I'm a bit busy these days.

How long will it take to clean these?

They're dress shoes.

They're the pair that I cherish the most. My mom bought them for me on my birthday.

There's someone I really want to arrest,

but I'm going to wear these and show them off after I catch him.

So please clean them well, with all your sincerity. I'll be back soon to get them.

So with this video that we don't even know if it's real or fake,

you want to not only take down PD Hong's video but also post an apology video? After we've gotten over a million views?

Station Chief.

I'm certain this video is real. I've confirmed it with a professional.

Who's a more skilled professional than Dr. Pi in this field?

There is! He's called Detective Durian.

Who's that?

Anyways, please help us. Don't you think this seems like it would be an exclusive scoop?

Trust is the life of running a successful show. The risk of making an apology requires a guaranteed benefit to counteract it.

If we correct ourselves, we just become wrong.

There is a guaranteed benefit to counter act it. He said he would call me back if we took down the video.

Who said that? This so-called Mr. Serial Killer? And if he doesn't?

Why are you being so pessimistic. We need to live with a bit more trust around here.

You want to live with more trust towards a serial killer?

I mean... what I mean is that he could be a serial killer who is unexpectedly like a knife to his promise.
(T/N expression meaning 'true to his word')

What if my neck becomes cut with that knife?

This is not just an issue pertaining to Fact Trackers!

Without any certainty, you definitely cannot do this.

What do you all think?

You want to conduct an interview with a serial killer that hasn't even been caught?

This isn't the first case in our nation's history.

It's the first in the world.

But won't it be too dangerous?

There's an issue of morals regarding what we can broadcast. Since even the Chief is against it, if things go wrong, I think you'll be fired...

We can't just keep acting leisurely like this. The broadcast is just a nose's length away, and it's true we're miles behind the other team.

It's another possibility that we post the video, but then the serial killer ghosts us.

They would have gotten everything they want at that point. Would they bother contacting us again?

We can make him contact us again.

How?

We provoke him.

He only told us to take down the original video and then post a new one correcting ourselves, but he didn't give us a detailed guide as to what content to include.

Hello, I am PD Kang Moo Yeong of Fact Trackers.

First, I offer you an apology.

The video that we released in advance which states that the murderer could be a "secret room" serial killer,

we've concluded that it was a hasty conclusion, so we are issuing a correction.

The "secret room" serial killer has been targeting the elderly because they were weak and easy to dominate.

We estimated that based on his crime pattern, he is smaller than normal,

and that there is a high possibility that he suffers from antisocial personality disorder.

As a result, the killer who killed Park Jae Min, a robust man in his 20s

would appear to be a little different.

PD Kang is properly messing with him.

She is definitely provoking him. That he doesn't have the capability to kill Park Jae Min.

With this much belittling, the "secret room" serial killer may even sue for damages.

He appears to be someone who has the shameful desire to show off his strength as a man by killing these victims.

What is that?

Oh, I'm sorry, I'm sorry.

It looks like he won't call, will he? It's been a while since the broadcast was aired.

Looks like the provocation didn't work.

Station Chief

It's Station Chief. What do we do now?

It can't be helped.

We go to Plan B.

- Do we have such a thing?
- We don't. I'm trying to think of one now.

Since he won't contact you, you will catch him yourself?

You are passionate as always, PD Kang.

If I don't get an interview with the "secret room" serial killer, my neck will be on the line.

I flattered you quite a bit, so how about helped me out?

Okay.

Why saying yes so easily all of a sudden?

If you pay me appropriate fees for my services, that is.

To someone who sold her dashcam because she didn't have money for food? How cruel.

To compare, I received 1,000,000 wons from Detective Jin last time.

For you, I will be sympathetic to your circumstance and settle for 300,000 wons. ($300)

50,000 wons ($50) including transportation and food.

PD Kang, I am Tak Won, the best profiler in all of Korea—

- 30,000 wons, then ($30).
- Hey.

PD Kang, are you really going to be like this? 30,000 wons? You are being too much.

Fine, 50,000 wons.

Of course, you should give me at least that much. Goodness...

End of negotiation.

Hold on.

Let's begin work now, huh?

Doctor?

You startled me.

There's a new product, so I'm testing it out. They may be deceased, but you still can't just use anything, can you?

How about it? Do I look alive?

Yes, you look so alive that you look like you will convulse.

What brings you here at this hour?

Doctor, when you were at the NFS, did you work on the "secret room" serial killing case?

I worked on all of them, except the ones that happened after I resigned. But why?

I am reporting on that case and I need you help, Doctor Lee.

If it's your request, PD Kang, I will do anything.

You rescued my Ka Eun, what wouldn't I do for you?

Oh, come on, you're embarrassing me. I really do love this attitude.

I heard about it from Mr. Tak. For something like this, we must help you.

Ah, indeed.

Red-Zone is a subcontractor of my private investigator firm, so you can negotiate with me on the fees.

Who says you can do that?

I know best what I am worth.

Unfortunately, I don't have money. Maybe we can work out a payment plan?

Then just give us 20,000 wons. ($20)

In that case, I will accept 15,000 wons. ($15)

I don't need money, PD Kang. We are on the same team, after all.

Look here, fellows. You can't sell your precious selves for such a pittance.

You should negotiate properly like I did

and receive at least 50,000 wons, don't you think?

Owner gives us 5,000,000 wons for our wages. ($5,000)

We don't need much money.

It's true.

Yes, some land I purchased previously is being redeveloped.

So I am not as rich as Detective Jin, but I do alright.

Do you need a part-time worker, by any chance?

How can this be?

Park Jae Min's DNA wasn't found in the suitcase.

If there were weapons in the suitcase, I'm positive we would have found Jae Min's DNA on it.

What were the results?

Just the grandma and grandpa's fingerprints and hair.

Results
99% mismatch

No wonder...

I thought it was weird we found it so easily.

What do we do now?

We have to start over from square one.

There's a singular survivor to the locked-room serial murder.

Witness

Son Ji Young. This woman?

I met her at the time,

I didn't see anything.

I was too scared.

she couldn't remember because she was so shocked. Then she disappeared.

There wasn't even a trace of her living anywhere.

She just moved out. She was in a rush, as if she was being chased by something.

She probably went into hiding because she's scared.

That's why I'm going to meet her family.

You, try to find out the call history of people who knew Son Ji Young.

See if anyone was in contact with her.

Okay.

I heard you were looking for me?

Hello.

I'm Detective Jin from the Geumpyeong precinct.

Are you Ms. Son Ji Young's father?

I got a divorce with my wife a few years ago, so it's been a while since I've last seen her.

I am aware of that. I came because I was wondering if I could get her phone number.

There's no way for us to find Ms. Son Ji Young or her mother.

I don't know either. We've never been in contact after we got a divorce.

Please don't come looking for me again.

Don't you think there's a reason for her disappearance?

I'll send you the address and the phone number.

I'll send you the address and the phone number.

I'll send you the address and the phone number.

I'll send you the address and the phone number.

I'll send you the address and the phone number.

143 26th Giyeon Road, Yang Mi Villa 2nd Floor

143 26th Giyeon Road

Is anyone home?

Excuse me?

Who are you?

Do you remember me?

10 years ago, I met Ms. Son Ji Young in the hospital ward.

Excuse me- Ma'am, please.

Can you please make just a little bit of time for me?

Why did you come looking for us again? Why?

Can't you tell from us living in hiding like this?

I'm very sorry. There has been another case in 10 years.

In order to catch the victim, we need Ms. Ji Young to act as a witness.

T-T-Then...

that's more reason that you shouldn't have come!

That thing happened to us last time after you came!

Please go back. Never come back!

Wait-

What do you mean, that thing?

Did someone come to your hospital ward 10 years ago?

Does that change anything?

Do you know how we've endured up til now?

Do you know how our child is living?

Ji Young.

The detective that we've met before is here.

He wants to speak with you.

Ji Young, I'll open the door, okay?

Ms. Son Ji Young?

Can you recognize me? I met you briefly 10 years ago.

I have a few things to ask you. It'll be short.

Why did you suddenly disappear then?

Did someone visit you in the hospital ward?

Was it... this person?

Leave. Leave. Leave!

Leave! Mom. Mom!

Ji Young, it's okay. It's okay.

Mom! Mom!

It's okay. It's okay.

- Ji Young! It's okay.
- I don't want to!

Mom is here.

Mom?

I told you you wouldn't be living even if you're alive.

If I meet you again, I'll definitely kill you then.

What's wrong? What?

Mom... He was here.

He's here!

Ji Young, come to your senses!

Mom, let's run away.

If you've seen that, then please stop coming here.

I'm sick of moving now.

I'm sorry.

This is an organization that protects and supports victims of crimes.

If you give them a call, you should be able to get assistance.

And this... It isn't much, but pleas use it for

your daughter's treatment and living costs.

I will be sure to catch that criminal.

The report is lengthy, but it basically means you still haven't been able to narrow down a list of suspects.

Well, we haven't found any conclusive evidence or found any witnesses.

I can't tell if you're all lazy or lack skill.

It's been two full days since my press conference,

but you must not be considering the citizens who are shaking in fear.

Next time, instead of a report that discusses just the process in length, bring me a report with some results!

I'm telling you to use any means necessary to catch the criminal!

Why is he telling us to do the work after saying whatever the hell he wanted during the press conference?

Goodness... Think of the citizens shaking in fear? He only cares about his promotion.

They said you can't even find dog poop to use as medicine when you're desperate. Where did this punk go?

Huh? It's coming right over there, the dog poop.

Who's dog poo?

- There's someone like that. You don't have to know.
- I feel like you're talking about me.

Amatta. Did you find her? Was it Son Ji Young?

I did, but it'll be too much to expect anything from her.

Goodness... This isn't some kind of repeat sign.

The case keeps returning to square one.

Wait ,wait. Son Ji Young?

Are you still thinking that the Utility Knife serial murderer is the person who killed Park Jae Min?

It's not like they're not related at all. We don't even have a single suspect!

Sure. Do whatever you want. Whatever.

Who could stop you? It'll be a relief if you get lucky.

However, don't act rashly like you did ten years ago.

- Nice! With age, you lose energy and give up quickly.
- This little punk-

Okay! This dog poop who can't even be used as medicine will try finding something.

Let's see.
Utility Knife Serial Killer

Is this all materials from the Utility Knife case?

Look through all of it from the very beginning. I'm sure we've missed something.

You want me to go through all of this alone?

If you have the persistence to call your ex-girlfriend 100 times, this will be easy.

With your endless attachment and shamelessness,

dig in deep through all of the files.

"Though I may not have caught my ex, I will definitely catch the serial killer!"

Use those qualities that made your ex girlfriend shiver in dislike

to your advantage here, okay?
- Sunbae, please!

Amatta, you embodiment of lingering attachment.

Good luck. I have lots of work to do.

Wow...

Hello.

Why are you so late? We're already done setting everything up.

I was stopping by the forensics office.

But don't you think that you're putting the cart before the horse? Why is it a given that we meet here?

Detective Tak's office is a bit hective, and Mr. Teddy's place is his business.

This office is the most spacious and convenient. Plus the AC is great, too.

What's the point of the AC being great when it's not even summer? Did you turn it on?

I'm just saying I'm comfortable here. Shall we start?

Jeez...

Is Detective Jin not coming? He said he was going to catch the culprit.

No chance. If the poodle joins us, he'll go to prison as soon as he's caught. We can't have that.

I need to get an interview first, and then hand him over to the police.

I mean, even if you don't want to use hand-cuffs, won't we need someone's wallet. It'll be costly to investigate all of this.

You must all have gotten a taste of money, judging from how much you spent last time.

For today, let's just go with us. We'll debate adding Detective Jin to the picture later.

- Sure.
- Okay.

Let's start.

First, what are the locked-room serial killings?

The locked-room serial killings refer to a total of 15 cases which range from 2005 until now.

The victims were all elders who lived alone.

The reason we started calling these 'locked-room murders' is because

the victims were all killed in their homes, but there were no evidences of people entering or leaving the premises.

In addition, all of the weapons used were materials found in the victim's homes.

The most obvious commonality in all these cases are the knots used when the victims were tied together.

It's a type of knot that makes it very easy to pull apart.

Things like this usually are done subconsciously, because it's so habitual for them.

That's exactly correct. It's likely this occurred as part of a habit in their workplace or hobby.

Then, what interesting details were found in the autopsy results?

The cause of deaths were all due to excessive bleeding as a result of lacerations and wounds.

However, the victims bodies show no signs of attempted defense.

Drug tests results turned positive for sedatives, but there were no signs of a needle being used on the victim's bodies.

It's obvious. They probably put it in some food before feeding it to the victims.

If they knew of all the elderly people who were living alone,

it's likely the criminal was a local social welfare worker or the director of the community service center.

No, not at all.

We found trace evidence in on of the screws of the cell phone that was left in PD Kang's car.

Hmm...

We found nitrogen oxide and phosphate traces.

Nitrogen oxide is typically found in industrial areas,

and phosphate traces are used in food processing or fertilizers.

So it's likely the criminal works in the food processing industry or a fertilizing industry.

There are plenty of such companies in Seoul. This will be as difficult as finding a Mr. Kim in all of Seoul.

Oh! I recently got a picture that tells us a bit more about the knot.

- What is it?
- Here.

It's the same knot, right?

It's near a dumpster. Where is this?

It didn't say the location. They just sent me this picture.

Don't worry. If it's an area, I can narrow it down.

In the case of a serial killer, if they don't get caught for their crimes,

they gain confidence and the location of the crimes committed get closer and closer to the actual home of the criminal.

It's called the return tendencies of a serial killer.

Look here. In the locked-room serial killer, they stuck around the northwest part of Seoul at first.

Recently, cases have been coming up in Dongpyeonggu,

so it's likely the criminal lives in Dongpyeonggu.

Dongpyeonggu... Dongpyeonggu.

Wait a minute. Dongpyeonggu...

Dongpyeonggu, huh?
Dongpyeong Foods

Oh right! There's a foods factory in Dongpyeong.

Then are we finally catching him?

Let's not jump to conclusions, Teddy.

We can't be sure yet that the person who left the phone in PD Kang's car is the locked-room serial killer.

He could've just been doing it for the killer.

We should still try searching.

Everyone should also keep an eye out for any waste papers, too.

- Okay. Let's go.
- Okay.

Sounds good.

What brings you here?

Hello. We called earlier.

I'm PD Kang from OCN's Fact Trackers.

Please come this way.

All of you worked after hours three days ago?

Did nobody leave earlier?

Not at all. That day was right before our delivery date.

But what case are you investigating?

This man must be the detective.

- I'm-
- Yes. He's Team Leader Jung Man Bok from the Geumpyeong precinct.

We're investigating a stolen vehicle.

Oh no! None of our workers would do something like that.

Though I'm sure you'll be able to find the culprit and do investigations.

I'm going to find that punk and bury him alive.

What?

It's just an expression meaning he will do whatever it takes to catch the criminal.

Oh... Yes, you should catch him.

Factories that produce carcinogens must be destroyed!

Are you okay?

I'm fine.

I guess it'll be a bit difficult for the residents here.

I guess it's because the dust from the factory spreads throughout the town.

Wait. Then that means even if it isn't an employee at this factory,

if they live in this village, nitrogen oxide and phosphates could be found in their personal belongings.

I guess that's true.

Sir! One moment please!

You dropped this.

Thank you, thank you.

Huh?

Sir, did you tie this knot yourself?

No. I brought what was in the market over there.

Market?

Wait a minute.

Hello, Granny.

Can I just ask one question? Did you tie these waste papers yourself?

This? Not at all. Dr. Do did it for me.

Dr. Do?

Not a thief!

There's someone named Do Gi Tae, who fixes all of our boilers for free in the winter when the days get cold.

A person who fixes boilers for free?

Hello, you've arrived?

You must have lots of boilers to fix, since the days have gotten so cold so suddenly.

I have to do whatever possible to make time to help the elders.

Thanks to you, Dr. Do, I feel assured.

The social welfare volunteer?

Yes? You know the trace materials found on the phone?

Could it come out from someone who fixes boilers?

It's possible. Nitrogen oxide is definitely possible,

and phosphates are used to clean the boilers.

I think we've found a prime suspect.

He's a boiler fixer who volunteers at the social welfare center.

For now, I'll send you his address, so please go look for evidence with Detective Tak.

We'll go directly to his workplace.

- Let's go.
- Sure.

Wait. I found it. Someone witnessed a corpse being disposed of.

The 20th case? The corpse was found in a drain next to Yangseo Bridge.

How did you know?

I've gone through those hundreds of times.

-It's been engrained in my head.
- Wow.

Then why are you telling me to go through these again?

In case I missed something. Let me see that.

Utility Knife Serial Killer - 20th Case

Evidence:
1. Triangular shape of victim's cloth
2. Blood sample on plastic wrap
3. Dash Cam Footage

3
Okay.

Dammit... the quality sucks.

Well, it's a dash cam from more than 10 years ago.

Even up until recently, it would have been difficult to recover such a low-quality video.

But now, technology has advanced so much that it's become possible.

It captures the screen every 1/60th of a second,

then increases the clarity of each screenshot before threading it all together again.

How long will it take?

I'll have to try it to know,

but if I can do it properly, I think the face could be identifiable.

It was worth saving all the materials from this case.

What if we can get the suspect's face?

Anyone can tell you this would be considered an illegal breach of private property.

If the police get here, we'll be caught immediately.

Shall we just return?

If I were my normal self, that's what I would do,

but I have a debt to repay to PD Kang.

Didn't you also get paid for your work?

Well, it wasn't enough for me to consider illegally trespassing in someone's home.

There's a fence and the gates are locked.

You said nobody was home. We can just hop the fence.

- What are you doing?
- Me?

Ouch...

- Ouch.
- Get out of there. Take this.

It hurts.

Wow.

Surprising, right? I know I normally just look intellectual and refined,

but I used to be in the special forces.

You don't look particularly intelligent and refined, but it is unexpected that you're from the special forces.

Look at this.

You want me to go in again?

You should be the one to initiate the illegal act of entering his home. I used to be a police, so.

I'm a necropsy doctor!

You used to be a part of special forces.

Good job.

Wow... Profiler Tak Won.

He found proper learning materials.

He stays fit to commit the perfect crimes.

Can you stay fit with this?

- S-Sunbae.
- What?

He went home?

Yes, he did. He left right after he fixed my boiler.

You don't look like thieves.

Um. We're YouTubers who explore deserted homes.

I guess this house wasn't deserted, assuming you're the home owners. We apologize.

You thought this normal house was deserted?

Yes, well. We must have made a mistake. Why don't we leave?

I think you've seen too much for me to just let you go.

You're one, and we're two.

So what?

I'm just saying in case things get physical, the situation will likely turn in favor against you.

Forget it. Attack me at once.

At once?

As someone who used to be a part of the special forces, I decline such unfair conditions.

I'll start. Oh, you're taking it off?

Okay then. I will also.

Hold this.

Sunbae! Sunbae!

B-Blood.

Im my simulation, I wasn't supposed to get a bloody nose at this timing.

Next. You.

Avenge me.

I think you're underestimating me.

You're judgement is correct.

2:0

Then I will also... Oops.

It's you. The profiler that was adopted into the States and returned with high honor.

Return with high honor?

I'm just working as part of a pyramid scheme.

You told me it wasn't a pyramid scheme.

Networking Marketing is basically a pyramid scheme.

But you eventually found me out. Good for you.

I'll take it as a compliment.

What do you mean, take it as a compliment? We're about to die because of you.

You're going to die anyway. It's good to be complimented beforehand.

Sure, sure.

But... sir. If you do this in your own home,

wouldn't it break your history of locked-room serial killings?

You have a reputation to uphold.

That's just something that people like you, who like patterns, made up for me. I don't care.

He says he doesn't care. All we have to do is just die for him.

Shut up! There's two of us, so it'll be difficult for you to get rid of our bodies.

That's my problem. Worry about yourselves.

Wow...

I've only ever killed wrinkly old people.

I'm so excited to be cutting into soft and clear skin.

Wait, serial killer sir!

You'll definitely make a mistake if you suddenly change your methods of killing.

On top of that, we're not great candidates to be victims of a crime.

You talk too much.

Were you here the whole time?

Are you not hurt?

Locked-room!

Locked-room serial killer!

Was it you?

Locked-room!

Locked-room!

Serial killer! Serial killer!

Wow, he did it! He did it!

Want to play with me?

Teddy!

It's endless.

Are you the boss?

I'm not the boss, but I am CEO.

Yes! Yes!

There you go!

He's stronger than I thought.

Are you okay?

Blood...

Are you okay?

Here.

Teddy. Here.

Yeon Jang.

- Are you alive?
- Of course.

PD Kang! PD Kang!

What happened? Are you okay? How much did you get hit?

Just once.

- Once?
- Yup.

Is that what's important right now? Is it?

Hurry up and untie me.

I'm okay PD Kang.

Even in this emergency situation, I was calmly stalling so you guys could get here.

You saved your life with just your words.

As expected, Mr. Tak!

Thank you, Teddy.

Shut up and change your underwear.

What are you talking about?

My underwear is very dry right now.

If you can't believe me, let me just-

Why won't you untie mine?

Huh? The knot.

We can't just get rid of such decisive evidence.

Exactly.

Why did you untie him then? Why me?

I mean, he got hurt.

I need the hospital. Hospital...

He doesn't look that different from how he usually looks.

Tak Won, you need to learn to think before you speak.

Huh?

You need to remember you cannot defend yourself right now.

Okay?

Okay, let's go move him.

- Let me go.
- Just stand up exactly like that.

Exactly like that. Let's go.

Ouch.

Untie me!

I don't think this is a police station. Who are you guys?

I kind of hate that a serial killer is angry at me.

You're the one who broke your promise. How dare you ghost me?

You're the one who provoked me first.

What? Saying you're undersized, anti-social, and have a personality disorder?

It's all correct.

Hey, you punk! All the people you killed

were weak and frail elderly. Do you know that?

They were all just disposable people who were useless to society.

They're just pest that eat up the money of tax payers.

It feels weird that a serial killer is worrying about tax.

So weird. Don't you agree?

Hey you bastard.

Do you think you'll never age?

Who are you to judge their lives as you wish?

Are you using violence because you can't handle me with just your words?

Seeing someone who killed fifteen people talk about assault

is pissing me off.

Sure, it's assault!

Wait a minute. Wait.

Anyways. Is what you said before true?

Do you really know who killed Park Jae Min?

I wonder.

Serial killers have a tendency to claim that they've killed more people,

but interestingly enough, you're even claiming that it wasn't you that killed him.

But I didn't have a partner. That would be embarassing.

What does that mean?

You didn't have a partner because that would be embarrassing?

I don't want jjamppong.

This punk didn't like jjamppong, huh?

I don't want it.

- It's done.
- Huh?

Let's see... 14 - 9113

And... here.

T-this?

Ham Deok Su...

14-9113

Are you saying two people killed Park Jae Min?

There's an accomplice?

Yes, Detective Choi.

What?

Excuse me.

Excuse me. Wait...

By chance...

It is. It's Son Ji Young.

The only survivor of the Utility Knife serial killings.

Then he let her live, and then killed her again in 10 years?

Right in front of our precinct?

He didn't kill her here.

Son Ji Young lives in Janghyeonggu, so he intentionally disposed of her body here.

Intentionally? Why?

Because I keep digging into the case!

It must be a warning that he's sending to me.

What the hell?

Let go! My daughter...

Ma'am, please calm down.

My daughter...

No, Ji Young!

No! Get up Ji Young!

No...

Ji Young!

Ji Young, get up!

Is it wrong to want to reveal the truth?

Kang Ho, stop it.

The case is over.

There's another criminal. What do you mean, the case is over?

Isn't this suppression of the press?

It is suppression of the press.

So you're saying our program could be discontinued?

I'm going to prove that I'm correct take counteraction against you.

We're not so much a team. I'm the boss and you're my subordinates. Understand?

It's what the organization decided. We have a responsibility to follow the regulations.

I don't! I think that people

are more important that the rules.
