Partners for Justice 2 (Investigation Couple 2 / Gumbeobnamnyeo 2 / 검법남녀 시즌2)

The cause of death is brain damage led by the traffic accident.

The cause of the accident is...

unconsciousness due to acute poisoning of nitrous oxide.

The possibility of murder can't be ruled out of the types of death.

The family members here are...

all important testifiers.

And you can also be suspects.

Also, Cha Do Hee...

Prosecutor.

You should be investigating the in-laws, not me!

Why would I kill her?

I would have killed him too.

Do you any proof that I killed her?

Who in the world is the culprit?

We're from the criminal department.

I'm Prosecutor Do Ji Han.

Why are you...

We just need a moment.

We're busy. What is it this time?

The culprit who murdered Cha Ju Hee...

has been found.

Do you know what this is?

is there more to see? What do you need to find?

Something in the car that wasn't there before.

- What is this? - This... This is that!

The trunk of the vehicle was mostly destroyed...

when Jang Ho Chul scrapped it.

This is all that was left.

And it used to look like this.

Cha Ju Hee had this ball...

in her car every day to use at the gym.

And this was the instrument...

of Cha Ju Hee's murder.

Before committing the crime,

the murderer bought the exact same ball.

Thank you.

It was injected with N2O instead of air.

The murderer poked a hole in it,

and switched it with the one in Cha Ju Hee's car.

She suffered...

from acute N2O poisoning in the sealed car.

Then she lost her consciousness and died of a car accident.

It was close to a perfect crime which no one imagined...

this simple sports equipment...

could be used for murder.

However, this gym ball gave us clues...

to identify the criminal.

This person handled N2O often.

This person knew well...

what was in the crashed vehicle.

This person had access to Cha Ju Hee's gym ball...

and knew her daily schedule.

From the collected piece of gym ball in the car trunk,

a fingerprint was found.

It was her husband, Jang Ho Gu.

On the day of the accident,

Cha Ju Hee left her apartment parking lot...

and bought coffee...

at a near coffee shop she often went to.

Jang Ho Gu, who was well aware of her routine,

was waiting there for his wife to appear.

And...

he was caught on a security camera of the coffee shop...

switching his N2O-filled gym ball...

with the one in the victim's vehicle.

And we were searching...

the cameras of her apartment parking lot.

It's no wonder we couldn't find anything.

Wait.

The takeout cup Cha Ju Hee bought that day...

was left in the vehicle as evidence.

Your son...

Your son killed my daughter!

How could he do that?

Mom, why would he do that?

Why did he kill his wife?

This conversation was recorded by Jang Ho Gu.

It was deleted before,

but the NFS digital forensic team was able to restore it.

Are you also treating me...

as a gold-digger?

I heard...

I'm not the first one you married.

And?

You won't even make excuses?

Don't you have anything to tell me? Are you not apologizing?

This is better.

You must've grown tired of me.

- Let's stop this. - Stop what?

Is this who you really are?

So is it money that you care about after all?

And you're all innocent?

You've been following me?

You're quite scary, aren't you?

Let's get divorced.

I want a million dollars for alimony...

and a half of this house.

Then...

what about our child?

Don't worry.

I already got an abortion.

The marriage he pushed ahead despite his mother's objection...

turned out to be a lie.

And he felt betrayed.

He elaborately planned a perfect crime.

Your husband is very attentive.

You two look good.

But he was anxious about murdering his wife.

At the same time,

he eventually met his absurd death.

Baby.

Baby!

What's going on?

It's nothing.

Be careful.

Baby, look out!

That lousy boy.

The arraignment right was nullified...

due to Jang Ho Gu's death,

and this case is closed.

Bring my daughter back!

Give me your phone.

Your son killed my daughter!

- Bring my daughter back! - Calm yourself.

Mom?

They brought me here, and it was nothing.

Yes.

- What are you going to do? - Kill me!

How will you compensate this?

Bring her back, you materialistic hypocrites!

The party of the jerks is finally over.

We should go drink some soju.

We're in the middle of the day and we have a lot to do.

It turns out it was a sad ending.

Right.

We should go drink soju.

- Yes! - I'd love that.

Let's go get soju.

What are we eating?

It's finally over.

That was something else.

The husband was the murderer?

(Seo Hyun's preschool, "We're closing an hour early.")

My goodness.

How did I miss that text?

I have to call the baby sitter.

Hello?

Yes.

What?

Seo Hyun got what?

Where is that?

What happened?

Seo Hyun...

Seo Hyun got in a hit-and-run.

I have to go now.

Yes. Hello?

Yes, I'm coming now!

I'm looking for Han Seo Hyun.

Seo Hyun!

- Wait. - I'm Seo Hyun's mother.

- Intubation. - We're diagnosing her right now.

(Intubation: placing a breathing tube)

Her front tooth!

Not her front tooth.

Give me the tube.

Squeeze the bag.

She'll be fine.

There's no fracture, and her breathing is restored.

Also her front tooth isn't damaged.

Thank you, doctor. Thank you.

Is Seo Hyun fine?

I should have watched her longer.

She's Dr. Han's daughter?

Yes.

But...

a hit-and-run?

I couldn't find her baby sitter.

I dropped her off thinking the baby sitter would come soon,

and made a U-turn down the street.

Then I found her on the ground...

and saw a car driving away.

It looked like the car hit her and took off.

I took the child to the hospital as soon as I could,

so I didn't have a good look.

Do you remember the model?

It was a black sedan.

- A sedan? - Yes.

I should have seen the license plate.

Is the preschool's vehicle a ten-passenger van?

Yes. Why?

Why are you lying?

- You hit the child. - What?

No, I didn't!

Why would you blame me?

The height of a sedan's bumper is within 40 cm.

But the child's injury is at a height of 50 cm.

That's the height of a van's bumper.

No. I didn't do it.

I'm telling the truth!

- Is the van in the parking lot? - Yes.
