[ TEAM BULLDOG: OFF-DUTY INVESTIGATION ]

[ TEAM BULLDOG: OFF-DUTY INVESTIGATION ]

Don't tell me you did this.

Gosh.

How could he kill someone

as soon as he escaped?

So, to sum up...

I'm scared to even touch this.

Our website is down, and we can't work

because we're getting too many phone calls.

How are you going to fix this?

If you're leaders, you should be working properly!

Still, thanks to this, people stopped paying attention

to your son's drunk driving case.

Is that important right...

Really?

No matter how crazy he is about murdering people,

how can he do that right after he escaped?

My goodness.

Are you sure it's him?

I'm sure. It's him.

It's his signature.

People know that it's a butterfly shape,

but they never disclosed this specific shape.

Oh, right. That's true.

[ Then we can't just assign this case to any other detectives. ]

Have the best detectives from Provincial Special Detective Division investigate.

If this gets in the way of me going to the headquarters,

you guys are done too. Got it?

Yes, sir.

Get a move on before the public sentiment gets worse.

And Chief Park.

Yes, sir.

You put him in jail seven years ago, didn't you?

- And you became the chief because of that. - That's right.

Then you get him this time no matter what.

Work on your own apart from the special team.

I'm making this clear.

Whoever gets him first will get the credit.

Okay?

I'll arrest him again no matter what.

[ Scientific Investigation ]

There's no sign of forced entry.

Perhaps the perpetrator was already inside.

Or was he someone the victim already knew?

We'll know once we check the surveillance footage.

- Good work. - Oh, right.

I'm going to go home now.

You little...

[ Do Not Enter, Police Line ]

There it is.

Gang-ho.

Look at this guy.

He cut the line.

[ Emergency Transport, Ministry of Justice ]

[ Emergency Transport ]

[ Serial Killer Jang Min-gi and Gangster Kang Soo Escapes ]

[ Jang Min-gi, Kang Soo ]

[ Nearby residents are nervous due to their escape in broad daylight ]

My gosh, it's like a scene from a movie.

The news never gets boring these days.

All the channels are talking about this. We can't fall behind.

We need to decide what we're going to focus on.

Bingo.

The other channels are focused on their past crimes

and on trying to find their whereabouts.

But we're going to talk about something that people have failed to question.

The correlation between Jang Min-gi and Kang Soo.

The two prison guards and the truck driver died on the spot.

And while the other prisoners were injured,

Jang Min-gi and Kang Soo were the only ones who escaped.

This may seem like a DUI accident

because the truck driver was drunk and ended up dying.

But what if this accident was planned?

So you want to question if the escape was accidental or planned

and if the serial killer and gangster planned this together?

I guess we could do that.

Then we should also look into the driver who caused the accident.

I'll check if the two criminals might've met in the past.

I'll announce on our webpage that we're open to receiving any information on them.

Okay.

Let's make sure we hit 4.5 percent for our TRP.

- Good luck. - Good luck.

Let's do this.

The banner on the webpage is too small.

Can you move it to the center?

Yes. I'm checking our webpage.

[ Waiting for tip-offs on Jang Min-gi or Kang Soo. ]

Moo-young, do you still have the files regarding the butterfly serial killer?

Why? Do you want them?

Why are you crying?

Because I'm upset that the ratings won't go up.

Your ugliness upsets you,

while my life frustrates me.

Hey, wait.

Here.

I'm always amazed

by how you find what you need in this pile of trash.

It's really an amazing skill.

Nice. This is new.

- Did you just say "trash"? You jerk. - Thanks for the files.

My gosh.

He's so annoying.

[ "Fact Check" Tip-off Board ]

Let me see.

There's absolutely nothing.

My gosh.

What?

[ I was in the same prison as Kang Soo and Jang Min-gi. ]

[ Geumpyeong Police Station ]

Kim Jin-gyeong, the first victim of the Butterfly Serial Murders.

[ Age, 32 years old. ]

[ She worked at a bank, and her body was disposed of near a mineral spring. ]

[ There was a butterfly signature on her neck. ]

[ The second victim was Joo Hyun-jeong. Age, 27 years old. ]

[ She was a nurse, and her body was disposed of in a parking space. ]

[ There was a butterfly signature on her hand. ]

[ The third victim was Shin Young-eun. Age, 38 years old. ]

[ She was a civil servant. Her body was disposed of by a river. ]

[ There was a butterfly signature on her foot. ]

My gosh!

[ The fourth victim was Lee Ji-hyeon. Age, 43 years old. ]

[ She was a lawyer. Her body was disposed in a park. ]

[ There was a butterfly signature on her cheek. ]

And this is Lee Seon-mi, the victim of the most recent murder case.

She's 45 years old and an OB-GYN doctor.

She was murdered in her house.

[ As you can see, there was a butterfly signature ]

[ engraved on her body just like the previous victims. ]

That is all.

Hey, there's a serial killer roaming around in our district.

I can't believe you just yawned.

I stayed up three nights in a row to catch a culprit.

- Sorry, sir. - This is exactly why

the Provincial Division looks down on us.

I mean, what's the difference between us and them?

Our investigation budget.

You should give us more money.

Keep your mouth shut.

Hey, don't you want to become the chief?

Once I get sent to Seoul, you should take over this seat.

Don't you guys want a promotion?

Are you going to live like this forever?

The commissioner promised that whoever catches them first

will be the one to take credit.

And that should be us!

We can't let the Provincial Division take all the credit.

Who arrested Jang Min-gi when those guys

- were on the wrong track? - We did, sir.

- We caught him, sir! - We caught him, sir!

Are you going to let this jerk roam around like this?

- No, sir! - No, sir!

We should be the ones to catch him again!

Let's go to the Seoul Metropolitan Agency. Let's aim for a special promotion!

- Yes, sir! - Yes, sir!

Okay, let's get a special promotion

and eat ribeye together!

- It's on the chief! - Nice!

- Thank you, sir! - Ribeye!

Ribeye... Okay.

Okay, fine.

[ Police inspection ]

[ Major Crimes Team One, ]

[ search every single place where Jang Min-gi could be hiding. ]

[ Team Two, check all the security footage near the accident site. ]

[ Team Three, make Jang Min-gi's composite, hand them out, and answer tip calls. ]

Yes, please give us a call.

What is this?

Why are so many people wearing masks?

Maybe the fine dust levels were bad that day.

Fine dust is getting in the way of our investigation.

Why are so many people wearing hats?

Who ordered cheonggukjang? Your food is here.

Over here.

Gosh, that's a lot of food. It smells amazing.

Put it here. Thanks.

Gosh, it stinks of cheonggukjang.

Gang-ho, you can't spend your entire budget on food.

Pho, sushi, malatang.

Are you trying to taste all the foods of the world?

You're not even paying attention to the videos.

- I bought this with my money. - You punk.

Why are you so selfish?

Do you think we like eating ramyeon?

I love ramyeon.

I already bought grilled beef for everyone yesterday.

- I just didn't invite you. - Why not?

If you have too much energy, you'll only nag at me.

I'll take you to a salad buffet next time

so you can eat a lot of vegetables and become calmer.

If you keep acting up, you'll have to pay for it one day.

Let me do my job before that happens.

Dae-jin, rewind that part.

- The hand that's cutting the wire. - This part?

Stop.

Look. It's a burn mark.

You're right.

There should be a medical record for this.

Way to go, Gang-ho.

You're amazing.

Wait. Did Jang Min-gi have a burn scar?

- Just a second. - Let's check.

[ Name: Jang Min-gi, Date of Birth: April 27, 1981 ]

No, there's no scar.

Then what is this?

Do you think Jang Min-gi might not be the culprit?

Then what about the butterfly signature?

It doesn't make sense.

Do you think it could be an accomplice?

I hope you understand.

This car belongs to the company, so if I leave it vacant for too long,

I get a call from the company right away.

I'm just grateful that you agreed to do the interview

Everything will be fine as long as you blur out my face.

Of course. Don't worry.

Did you say you served time in the same prison

as the two fugitives, Jang Min-gi and Kang Soo?

To be honest, the moment I saw the news regarding their escape,

I instantly had a feeling that they must have

- planned it together. - I see.

- So you think it was planned? - Yes.

They fought like crazy the moment they first met.

But once they cleared the air,

they suddenly became pretty close.

I guess gangsters are also scared of serial killers

seeing that Kang Soo became Jang Min-gi's minion.

But then again, Jang Min-gi killed someone as soon as he escaped.

That already shows that he's one of a kind.

[ I could tell that he was brutal. ]

Did you notice anything else?

That's all I know.

Did that help?

Yes, of course. It helped a lot.

I'll get off over there.

Okay.

- Sir. - Yes?

This isn't much, but I'd like to thank you.

- Goodness, that's not necessary. - No, but...

No, it's okay.

I only told you a few stuff.

- Okay then. Thank you. - No problem.

- Thank you, sir. - You're welcome.

- Hey, wait. - Yes?

You need to pay for the taxi fare.

This is the company's car.

Oh, right.

Goodness.

I was going to pay him 50 dollars for the interview.

No wonder he went to jail ten times for fraud.

Seriously.

Hello?

I see. You're done moving my stuff to the new house?

Thank you so much.

I was surprised to get a call from you.

What are you plotting?

You even got Kang Soo out.

I don't follow.

Even if we did,

it's none of your business now.

Don't cross the line.

Don't make me get involved.

I don't want to be on bad terms with you either.

We used to work together, you know.

If you want to continue to be on good terms with me,

don't make a mistake.

It's not just about me.

Ten years are long enough to change everything.

Oh, right.

[ Year 2003 ]

Stop what you're doing!

Who's the boss here?

I see. Are you the ones who made a move on the Ohgwang Gang yesterday?

We can get to know each other later. Let's get this started already.

My boss is past his mealtime.

I tend to get a bit sensitive when I skip a meal.

Hey.

You punk.

Kang Soo! Kang Soo!

- Hey. - Kang Soo.

Punk.

You!

[ Construction Labor ]

[ Karaoke ]

We took over the whole district.

Where to, sir?

I'm hungry.

Let's go and eat rice soup.

Rice soup again? My gosh.

Sir, we should name ourselves too.

Like what?

The Three Musketeers?

Or Red Zone?

How about Red Zone?

Red Zone? What's a red zone?

[ It's scary. It's red. ]

- Hello. - Hi, Gang-ho.

Are you all right?

My gosh, I can't believe this.

Really?

You're beautiful.

Gosh, you have good eyesight.

What? Why are you here?

You have a serial killer on the loose.

So you guys won't be able to go home for a while.

I brought some underwear and socks.

Seriously, ma'am.

Your family had police officers for three generations.

You're so considerate.

This is why I love you, ma'am.

That's mutual.

Gosh, there's one in mesh.

Ma'am, you're so thoughtful.

Hey, don't get ahead of yourselves.

I'll charge you for those.

I'll get going. I'm sure you guys must be very busy.

Okay. Get home safely.

Okay.

Go on and take her home.

Gosh, no. You're all busy.

It's okay. It's pretty late. Come on. Take her home.

Let's go. I'll drop you off.

Don't touch the mesh one.

- Take care. - Bye.

174 dollars for the underwear and socks.

I knew this was all in your plan when you were acting all generous.

You're so generous

when you're spending money to investigate and as consolation money.

What? I can't ask you for money?

Besides, we'll really go broke

if you keep spending money like water. Okay?

Your husband who was my father

had been collecting money for 30 years.

We have a long way to go to spend all of his money.

Let's go.

Even so, give me some money.

You're my son.

- No. - Hey!

Wait. Aren't these all mine?

- Right? Mom. - It's nothing.

Did you throw out my stuff in the storage?

It's not what you think.

No, I know what you did.

I told you never to throw this out.

- It's not what you think. - Come on.

Gang-ho.

- This is... What's all this? - Gosh.

Did someone move in here?

It's... Yes, you punk!

I rented out the storage room.

What are you talking about? Rent out?

Why would you do that without discussing it with me first?

This is my house.

You're living in my house for free.

Why would I discuss with you

about renting out a room in my own house?

You didn't let me use your father's money.

So this is my solution.

I told you to pretend that we don't have.

That's not our money.

My gosh, you are such a clean and upright son.

Shut your mouth.

Make sure to wire me the money for your monthly expenses.

And how come you never got a raise

over the last five years?

Gosh. I don't know. Let's talk later. I'm busy now.

Ma'am, you're back.

There's a lot of stuff inside.

Can I throw them all out?

- What? - Well...

Hey. You...

What are you doing here?

Let's cut to the chase.

Move out first thing tomorrow morning.

Why would I do that?

I signed the contract with your mother, not you.

So you're going to live in this house with me?

Don't put it that way.

I'm not living with you.

The room is detached from your house.

I don't care about that.

The room is moldy.

No one can live in there. It's just a storage room.

My mother fooled you.

What? Should I register this as a fraud?

Gang-ho, I did no such thing.

She saw the room herself and made her decision.

Before you get dry patches on your face because of the mold,

you should move out while I'm being nice.

If you can return my deposit and the month's rent I paid in advance,

pay the moving fee,

and compensate me for the psychological damage you have caused,

I'll think about moving out.

I'll cover the moving fee.

As for the deposit and the rent...

I don't have it. I already spent it all.

For my trip savings to Hawaii.

How much is that in total?

5,000 dollars deposit and 200 rent.

And 1,000 dollars for the moving fee.

No. It's 2,000 dollars to move back.

As for the psychological damage,

it's about 10,000 dollars.

What?

You only moved in an hour ago.

Are you saying

you had 1,660 dollars' worth of psychological damage every 10 minutes?

Goodness. What kind of dummy

divides the money by the minute to evaluate the damage?

I'm in despair, enraged, and dejected

as I can't move in here.

And you must consider the anxiety I have to move somewhere else.

Ma'am, your son knows nothing about women. This must be hard on you.

Gosh, I finally have a person with whom I see eye to eye.

Right. For your information, he has 120 dollars

in his paycheck account.

What?

That's right. He's broke.

Mom, come on!

Anyway, I didn't say yes to this.

Let's talk about this later. Okay?

Yes, sir.

By the way,

I guess your son isn't financially well-off.

That jerk is rich.

He carries around a black credit card.

What? You just said he's broke.

He has 120 dollars.

On paper, he's rich.

But in reality, he's broke.

There's a story behind it.

I already have too much stuff,

but now I have to keep this lousy cop's stuff too.

- Yes, Mom. [ - Where are you? ]

Where else? I'm home.

[ You've got to be kidding me. ]

[ I'm at your place right now. ]

What?

Then you must know that I moved out yesterday.

[ Yes, you wench. ]

[ Now you're moving in secret and trying to cut ties with me? ]

I didn't move in secret.

I got kicked out because I was behind my rent.

Now I moved to a storage room where I pay 200,000 per month.

Moo-young.

Goodness, I know we're always tired,

but you look especially bad today.

Did something happen?

I moved yesterday.

Again?

Well, you've got sued a lot.

Did you cover them with your house deposit again?

This is why it's so hard to achieve justice.

- To achieve ratings, you mean. - Be quiet.

Shut it, Mr. Never-Had-A-Girlfriend.

- What is it, anyway? - Oh, this?

This is the wife of the truck driver, Kim Jeong-man, who caused the crash.

I've looked into it.

Kim Jeong-man grew up with Kang Soo in the same town.

So the driver of the dump truck was a friend of Kang Soo?

- That's suspicious. - That's why I dug further into it.

This is the case where Kang Soo was a suspect

of the murder of a worker two years ago.

And this is the butterfly serial murder of Jang Min-gi.

These cases were assigned to the same prosecutor and police officer.

What?

The prosecutor and the police officer for the escaped convicts were the same?

I mean, this could be a coincidence,

- but we can make a story out of this. - Right?

Yu Seong-guk of Seoul District Prosecutor's Office,

and Seo In-jae of Geumpyeong Police Station.

Wait, isn't Geumpyeong Police Station

- where the lousy cop works at? - Yes.

Prosecutor Yu Seong-guk...

- Hey, is he the current mayor of Seoul? - Yes.

His last case before he became a politician

was this murder case of the worker.

Any other prosecutors would've put this guy in jail for about ten months,

or in probation.

But he demanded ten years' imprisonment with additional punishment.

He became the talk of the town at that time.

That's right. That's how he became the mayor so easily.

This won't do. I should go investigate the nearest places.

- Where... - I'm going. Sorry.

[ Geumpyeong Police Station ]

Excuse me.

Pizza delivery.

Hi.

Hey.

I'm here to collect the bowls.

What? I put them out earlier.

Right there.

[ Special Investigation Headquarters ]

Thank you.

- I'm here to clean. - The cleaning lady is here.

Oh, right. We're going to clean this place ourselves from now on.

Thanks, anyway.

[iQIYI Ver] OCN E03 'Team Bulldog: Off-Duty Investigation' -♥ Ruo Xi ♥- Synced with Subcake Android

Hey, Ms. Kang.

You didn't move out yet.

Are you trying to hold out?

I'm actually here to report an abusive landlord.

Where should I go to?

Where are you going?

Don't you see it over there?

We're working on a classified case, and no reporters can come in.

I'm here for a different case than the butterfly case.

Goodness. How dare you give me that lousy excuse?

- Aren't you that lady from Fact Bomb? - What?

It's called Fact Check.

How can you confuse those two?

By the way, are you here to see Gang-ho?

- No, I'm not. - No, she's not.

People have the right to know.

Don't you think it's unfair to keep your investigation a secret?

It's more important to make an arrest.

Do you even know the fugitives had the same prosecutor and police officer?

Detective Seo In-jae from this station was in charge of both cases.

What did my Section Chief do?

That could be a coincidence.

Anyway, let me just meet with him.

Gosh, I said no.

Goodness, what are you doing?

What's wrong with this woman?

Do you want to get locked up and come to your senses?

Gosh, Detective Min, arrest her.

I'll leave.

What was that? What's wrong with her?

[ Geumpyeong Police Station ]

[ I'm going to go to the prison to see Jang Min-gi's visitor's log. ]

[ I see. I'm sure his accomplice would've visited him. ]

He had an accomplice?

Is it Kang Soo?

No way. Then he couldn't have visited him.

What's going on then?

An accomplice in the butterfly case?

- What? - Gosh.

What are you doing? Get off now.

No. Stop.

I'm going to arrest you for sexual harassment.

Sexual harassment?

I was just trying to help my landlord with his seat belt.

Forget it.

Do you think I won't kick you out if you do this?

Goodness, you're so sensitive.

Okay, let's go. Vroom, vroom.

Do you even know where I'm going?

Seowon Prison.

I want to see the visitor's log too.

They won't let a civilian like me see it.

How did you know that I was going for that?

This is your chance to repay me.

What are you talking about?

What? How about the twin brother, Kim Min-soo?

You only caught him

thanks to the video I shared with you.

So repay me now.

I'm only going to show you the visitor's log.

Deal.

That's all right.

Hello.

I got it.

Can I see the escaped prisoner Jang Min-gi's visitor's log

and the mailing list?

- Kang Soo's too. - Kang Soo?

Yes, please.

[ Visitor's log ]

[ Tak Won ]

"Tak Won"?

That private detective?

Why would he visit Jang Min-gi?

Well. I'm sure it was for an interview.

From what I remember, he caught Jang Min-gi

while profiling the butterfly case.

Wait.

But Jang Min-gi kept refusing to see him.

All the letters were from his mother.

But Jang Min-gi's mother passed away a few years ago.

What?

Wait.

[ Geumpyeong Post Office ]

Still, he received letters until a month ago?

That's scary. Was it a ghost?

Why would a ghost send a registered mail?

- Because it's quick. - My gosh, come on.

The registered mail was sent on December 7.

Then it's someone among these people here.

Wait.

What? Mr. Tak?

What?

Could he be the accomplice?

Director Kang, over here.

I guess they're here to shoot a TV show.

He really must be a famous detective.

See?

- I told you I saw him on TV. - I guess you were right.

Wait right there.

Detective Jin is here as well.

Police officers sometimes ask me for help as well.

- I see. - This is just a side job.

I do this to make people happy. Hundred Year Good Life.

By the way, she's 40 years old.

But she looks that young

- because of this soap. - You're 40?

- My goodness, she looks so young. - No...

- Seriously. - Exactly.

It's unbelievable.

She doesn't look 40.

- She looks like she's in her 20s. - Exactly.

This must be really good.

How could you call me 40?

Are you going to keep lying to people?

I'll give you a 30 percent discount

for our hair loss shampoo.

You give me a headache.

What?

You have no scar.

You're not the accomplice?

What accomplice? Who?

The accomplice has a scar on his wrist?

Seeing that you're talking about an accomplice,

you must've found a new suspect. But cops always make the wrong guess.

What's the matter with you? What do you have against cops?

Jang Min-gi

isn't the actual culprit of the Butterfly Serial Murders.

What is the matter with you? Will you please stop the nonsense?

You were the one who did the profiling

and had Jang Min-gi get sent to jail.

Wait. Can I film this?

- And my consultancy fee? - I'll pay you

minus the money for the organic soap. It ruined my skin.

Deal. Shoot the left side of my face from a high angle

so that my jawline shows.

Jawline. Okay.

What a joke.

Here's a question.

Do you know where we are right now?

Where do you think? We're at a mineral spring.

Wrong.

This is where the body of the first victim of the Butterfly Serial Murders

was found in 2010.

Back then, the cops thought the victims were raped

because the victims were all women,

and there weren't any stolen items.

However, the test results

showed no signs of semen inside their bodies.

That's not enough to say it wasn't a sexual offense.

Maybe the guy was a perverted sadist.

- Wrong. - Will you stop?

The cops thought

that was Jang Min-gi's motive back then.

But if it was really a sexual offense,

the bodies would've been found somewhere covert

to prevent the cops from finding any evidence

that could lead back to him.

However, that wasn't the case with the Butterfly Serial Murders.

[ It's as if the culprit wanted the bodies to be found quickly ]

[ because he discarded the bodies in places with lots of passers-by. ]

[ The way he killed the victims were very simple. ]

[ But he used a very complicated method to discard their bodies. ]

[ It's as if his purpose was to dispose of them. ]

[ What's more surprising ]

is that we couldn't find a single clue or witness

even though the bodies were disposed of in places where there are a lot of people.

Hey.

Mr. Pyramid-scheme-hawker.

How does that prove that Jang Min-gi

isn't the culprit?

The murders weren't impulsive.

They were carefully planned.

But you think Jang Min-gi impulsively committed murder

right after he escaped from prison?

There's no way.

Let's say Jang Min-gi isn't the culprit.

Then that means the murders should've continued

even after he went to jail.

Correct.

I'm sure he secretly continued to murder people.

They just never got discovered.

Hey, stop showing off.

And tell me I'm correct as well.

I just feel really uneasy

because you kept telling me I'm wrong.

It's absurd.

He thinks people kept getting murdered

while Jang Min-gi was in jail?

I wouldn't say it's absurd.

You're trying to use this for your show, aren't you?

Gosh, that hawker is so weird.

He did the profiling.

But now, he says he's not the actual culprit?

You're even weirder.

Hasn't it ever crossed your mind that the police could make mistakes?

Just hurry up and find a new place.

I don't think you can afford

to pay me all that money.

I heard you're rich on paper but poor in real life.

I can't believe my mom told you that.

Anyway, I'm even willing to steal to give you back your deposit.

Are you serious?

If you really steal money, I'll move out.

"A cop turns into a thief". It's a great subject.

- Ms. Kang Moo-young. - Yes?

Get out of my car.

You're so coldhearted.

Drive a bit more.

Did you find anything related to the visitor records?

I thought we were onto something.

But I just got nagged at by a hawker.

What's that?

Oh, right. I have something huge.

Lee Seon-mi, the victim of the recent murder case.

They found the culprit's bloodstain on her teeth.

[ Culprit's bloodstain found on victim's teeth. ]

She must've bitten the victim's hand.

What? Then there must be a scar on the culprit's hand.

Yes, probably.

She bit him hard enough to make him bleed.

Then that means we might get Jang Min-gi's DNA.

But the blood got mixed

with the victim's saliva.

They'll call us if they find anything.

I know I'm right.

Jang Min-gi is the only person

who would leave a butterfly mark.

Okay, I'll check.

You two, go to a convenience store in Jiheung-dong.

Someone called and told us that he thinks he saw Jang Min-gi.

Okay, sir.

You can't see his face because of his hat.

But I had this taped to the counter.

And he looked just like him.

- Do you want a cash receipt? - No.

Pardon?

I said no.

[ 100,000 dollar reward Fugitive serial murderer ]

I got goosebumps the moment we locked eyes.

I'll collect the nearby security footage.

Okay.

Did you happen to see a scar

on Jang Min-gi's hand?

Or was he wearing a bandage?

I'm not sure.

I was so nervous, so I don't think I remember.

Okay. Can you give me this footage?

Okay, sure.

The victim bit the culprit's hand,

so that means there should be a scar on Jang Min-gi's hand.

But there's nothing.

I'm sure he secretly continued to murder people.

They just never got discovered.

Gosh, that's impossible.

Let's check if there were murders

that were similar to the Butterfly Serial Murders.

[ Case search ]

Wait a minute.

What?

[ Icebox, murder ]

[ "Dismembered Corpse Found in Icebox on Heungsan Mountain Trail" ]

"Heungsan Mountain Trail"...

"Heungsan"?

[ "Dismembered Corpse Found in Icebox on Heungsan Mountain Trail" ]

[ Do Not Enter, Police Line ]

Gosh, this isn't good enough.

Let's check the comments.

[ Wasn't that college girl found in an icebox in Danseong 5 years ago? ]

[ The college student in Daeeon-dong was found in an immigration bag. ]

[ A body was found in an icebox on a handcart in a dumping ground. ]

Okay.

"Danseong",

"icebox, corpse in public area."

[ Icebox, corpse in public area ]

What?

[ Today's unsolved case: Handcart dismemberment case ]

I found it.

[ Case search ]

"December 2013"?

This happened after Jang Min-gi got arrested.

[ Today's unsolved case: Handcart dismemberment case ]

[ In December 2013, a woman was found dead in a garbage dump... ]

- "The handcart dismemberment case"? - "The handcart dismemberment case"?

How long have you been working here?

It's been about 10 years.

I heard they found a dead body here seven years ago.

My goodness, don't even get me started.

I still get the chills just by thinking about it.

[ December 2013 ]

[ December 2013 ]

Darn it.

Had the handcart been abandoned for a while?

For about a week at the most.

The residents were complaining about it,

so I put up a note to take it back. But soon after, I took it away.

[ Moo-young, I sent the autopsy file of the butterfly case ]

[ and the handcart case by email. ]

Darn cops.

Hello.

[ Fish-shaped buns ]

You aren't good at this. You should stick to being a detective.

I'm not a detective.

I sell fish-shaped buns.

Good luck.

Thanks.

What do you want?

Have you been eating fish-shaped buns all day?

I'll keep watch, so go have some food.

Poor things.

Goodness.

What an awkward-looking couple.

Gosh.

Everyone's so clumsy.

[ Year 2012 ]

Is this my home?

It seems different from what I've heard.

Oh, welcome.

- Hello. - Have you been well?

Yes.

Excuse me, why are you standing in front of someone else's house?

I'm moving in here today.

Sorry? But I sold the house to them.

That can't be true. I have a copy of the contract here.

Here it is.

[ Lease Agreement ]

[ Name: Lee Sang-moon ]

My name isn't Lee Sang-moon.

Did you get scammed?

It's very common these days.

That must be it.

You should go to the police.

I'm the police though.

What the hell...

[ Certificate of commendation ]

[ Jang Min-gi ]

Is this everything?

You don't have any other furniture?

I thought the house comes with them.

You really have no clue about this area. You'd end up on the streets.

- Have some of this. - Thank you.

- This picture... - They're my parents.

I was adopted to the US when I was three

and came back to Korea after they passed away.

Thankfully, they kept reminding me that I was Korean.

Well, since it came to this,

you can stay here until you find a place if you'd like.

We have a spare room anyway.

- Mom, you don't even know him. - Gosh.

He's the police.

And I feel bad for him.

Gosh, whatever.

Do as you want.

♫ Happy birthday to you ♫

♫ Happy birthday to you ♫

- ♫ Happy birthday dear Mother ♫ - ♫ Happy birthday dear ma'am ♫

♫ Happy birthday to you ♫

Mom, make a wish.

This time, I prepared a Korean style gift.

Right. Your present last year was crazy.

How can you give lacy lingerie to an old lady?

This time, it's way too old-fashioned.

Even the old country ladies wouldn't wear this.

What are you saying? It's pretty.

Thanks, Won. I'll make good use of it.

My mom is always too generous on you.

Stop it.

Stop it.

Jang Min-gi, you're under arrest for serial murder.

- What? - Take him away.

- Mom. - Wait.

- I'm the police. - What are you doing?

What are you arresting him for?

- You should tell me what's going on. - Why are you doing this?

- Wait a minute. - Won!

- Won! - What did you say?

- Oh, no. - Please!

It's not me!

My goodness.

Min-gi. Oh, no.

What do I do?

[ Witness ]

The witness has studied criminal psychology in the US

and has been a profiler at the police for many years.

I'll ask you, sir.

By profiling,

I heard you can find out the suspect's personality, tendency,

their age, educational background, job,

and even where they live.

- Is that true? - It is.

You've suspected that the perpetrator

for this case was a taxi driver.

Is that true?

Yes, but...

The police arrested Jang Min-gi

based on the profiling

that the suspect is most likely a taxi driver.

The last victim got on the defendant, Jang Min-gi's taxi.

And there's a witness who can verify that.

I've also mentioned other possible jobs.

Yet you said the suspect is most likely a taxi driver, didn't you?

That's...

Witness, please answer the question.

Yes, I did. But...

No further, your honor.

[ Inmate visiting room ]

He refused to see you.

I think you should just head back again.

Goodness, Lady Sun-ja, you're so beautiful.

- Really? - Of course.

I've been all over town,

- but there's no one like you. - Come on.

Sit up.

Here's the mirror.

- Ta-da. - You covered my wrinkles so perfectly.

The old women I'm meeting today will be so jealous.

Does that mean you won't be raising the rent?

We'll see.

You can go now.

Go have fun in Apgujeong-dong.

Here.

You scared me.

I thought you brought her back to life.

She's the landlord.

So, why are you alone today?

I need you to look at something.

"The butterfly serial murder".

"The handcart dismemberment case".

You want me to tell you if they're committed by the same killer.

Yes.

They have more in common than I thought.

Both victims died by strangulation.

[ Strangulation: choking of the neck by hand ]

Look. Do you see the finger marks on their necks?

As you can see, both thumbs are way bigger than the other fingers.

Yes.

That means both cases

were committed by culprits with phocomelia.

Secondly, let's look at their method.

The victims for both cases

were hit on the back of their heads.

Therefore, the victims' skulls were all damaged.

The shapes are all similar,

so that could imply that he used the same weapon.

Right?

There aren't a lot of weapons that could form

such a distinctive crack.

By any chance, do you think you can find a butterfly signature

on the body of the dismemberment victim?

If we find the butterfly signature,

it means both cases were committed by the same culprit.

I'm not sure.

What?

The butterfly signature.

The culprit who committed the Butterfly Serial Murders

is also the culprit who committed the handcart dismemberment murder?

That means it wasn't Jang Min-gi.

The actual culprit is someone else.

[ How can we help you? ]

What's going on?

What are you doing here?

You little...

[ Jang Min-gi, Kang Soo ]

Okay, everyone.

The connection between Jang Min-gi

and Kang Soo isn't what we should be focused on.

Let's start over.

Have you lost your mind?

Why would you erase that?

Because we got it all wrong.

The culprit is someone else.

What we need to find out

isn't the connection between the culprits who are on the run.

It's the actual culprit of the Butterfly Serial Murders.

Because it wasn't Jang Min-gi.

Everyone thinks it's Jang Min-gi.

But we're going to find the serial killer that the police have failed to find.

We were wrong about everything from the very beginning.

The guy we need to find

is the murderer who's still somewhere out there

living among us as if nothing ever happened

and pretending like he isn't the murderer.

Do you all understand?

What are you doing?

You crazy punk. What is the matter with you?

I told you to find Jang Min-gi. What do you think you're doing?

Jang Min-gi isn't the culprit.

I have conclusive evidence.

Watch what you say. Do you really want to hang up your uniform?

Will you stop saying that?

It's so much pressure.

Gang-ho, I know your dad used to be my boss.

But there's a limit to how much I can take.

There's been another Butterfly Serial Murder.

- What? - What?

Hey, turn on the TV. Hurry.

Don't boss me around.
