Special Affairs Team TEN 2
You've reached 911. Please speak.
Hello? Please speak.
Save me... Save me...
Where are you right now?
Hello? Hello?
15 years
This is the case from yesterday.
As soon as we start to forget an old case, a new one pops up.
Is this why you called me?
There's something the media missed.
This is a recording of the phone call between the driver and 911.
Save... me...
Hello? Please speak.
Save me...
Where are you right now? Hello? Hello?
You!
"You?"
According to the crew that arrived at the scene...
...the door was locked from the inside.
No signs of trespassing.
Maybe it was the passenger?
The results show that she died before the driver.
She wouldn't have called for someone who was already dead.
Who do you think she was calling for?
Tetrodotoxin was found in both of their bodies.
This substance is a hundred times more powerful than cyanide.
One of the ingredients was globefish toxin, lethal dose of 2 mg.
Colorless, tasteless, odorless...
Shortness of breath... These are all characteristics of being paralyzed.
This is a sign that the victim was conscious until her last breath.
Even though she looks unconscious...
She could still see and recognize her surroundings.
I didn't know you studied toxicology.
The cause of death is the tetrodotoxin.
But there's one strange thing.
The toxin was found in the stomach for one victim.
For the other victim, the toxin was found in the blood.
How long does a full digestion take?
It usually takes around 6 hours.
They visited the restaurant at 10 AM and were found at 12 PM.
How could she have digested in 2 hours?
The method of entry was different.
A bar mistress and a doctor.
What an interesting combination.
Where were they headed this early in the morning?
It's the same type of mud as the ones found on Kim Min Sun's shoes.
It's strange.
A doctor should've known that breathing fresh air is vital when poisoned.
Kim Min Sun purposely went back inside the car to lock the door?
Yes?
Director!
I'm checking the globefish...
They're all homebred.
Homebred?
The owner must've received fake shipments.
Okay.
What's wrong if they're homebred?
There is no poison in homebred globefish.
Director Yeo!
Looks like this is a murder case.
The criminal poisoned the coffee...
...but made it look like it was the globefish.
After Kim Min Sun and Oh Hyun Joo drank the poison...
If the criminal cleared all the evidence inside the car...
There'd be no doubt that it'd look like they were poisoned by the globefish.
But Kim Min Sun didn't drink the coffee and so the criminal...
...stabbed her with a syringe out of shock?
And that's how the poison was inside her blood?
The mud on Kim Min Sun's shoes...
show that after being stabbed, she had nowhere to go except to her car.
The fear in the victim's eyes...
She saw the killer outside the window until her death.
She tried to call 911 inside the car but it was too late.
They used up an entire bottle.
Was there a grudge?
If the killer already knew where the two ladies were headed...
...he must've known them pretty well.
They must've been really close. Enough for her to call him out.
Why did the criminal throw away this picture at the scene?
Maybe there was a secret he was afraid would be revealed.
Were they friends who would die together too?
I Am
I can't believe it. A murder...
How did you meet your wife?
I was her professor when she was doing her residency.
Were there any medical accidents for someone to hold a grudge?
Her skills were exceptional.
She was always thorough with her work and had pride for her job.
She even received calls from hospitals in America.
Someone with that reputation just declined all the job offers?
Something doesn't make sense.
It was because of her handicap.
In order to be successful in this field, you have to be recognized.
Attending meetings and seminars is crucial.
But, her handicap got in the way of her chances to become greater.
It was aerophobia.
When did your wife start taking tranquilizers?
6 months ago.
She had insomnia so I prescribed it for her.
Was she always close with Oh Hyun Joo?
They were best friends.
They've been friends since childhood.
Have you ever seen this picture before?
It's my first time.
How was the money flow here? Any loans or debts?
Do you know how much income we make here?
Well. I guess there was a time when the business was unstable.
Was it 5 years ago?
You know that the bars closed down due to financial crisis, right?
The debt collectors were constantly bothering us.
But you guys got back on track fairly quickly.
The doctor lady solved all of our problems.
She brought all of her colleagues over to help raise our income.
I was jealous.
I wanted a friend like her too.
Even though they were childhood friends, it's hard to stay close...
...when working in two different fields.
But, their friendship lasted until the end.
Yes?
Pick up my calls faster!
You bastard, I tried.
Did you find anything from the evidence?
Only the fingerprints of the victims.
The toxin was only found in the syringe and a canned coffee?
Why was it only found in one canned coffee?
It was only found in one can?
- Yes. - Okay.
The bedroom is a woman's personal space.
There aren't that many women who would allow smoking...
...in the bedroom unless they smoked too.
Therefore, having an ashtray on the vanity table...
...proves that they didn't sleep in the same room.
Separation at that age means it's money or another woman.
Or both.
I found it!
Lee Jong Hoon.
Why did the criminal only poison one can?
There's only one reason.
He only wanted to kill one person.
Your wife, Kim Min Sun.
I guess you were trying to find this photo but couldn't.
Why did you have an affair with your wife's best friend of all people?
You received many benefits from your wife.
Did you try to file for a divorce using this photo?
As a doctor, getting the globefish toxin should've been easy.
You probably told Oh Hyun Joo to poison the coffee.
But Oh Hyun Joo ended up drinking the coffee by mistake.
So that's why you took the syringe and -
Enough.
This photo...
I took it and sent it to her.
What?
I wanted to confirm.
What?
Min Sun's intentions.
You finished a difficult surgery so let's eat something good.
What?
Hyun Joo!
Sorry you had to wait.
Around 5 years ago...
Oh Hyun Joo was always in our relationship.
Sometimes it seemed too much.
It also bothered me that she worked at a bar.
But I let it go because I knew Min Sun was going through a hard time.
But...
Who is it?
Hyun Joo!
What brings you here at this hour?
Didn't Min Sun tell you she was at Busan for a seminar?
I didn't come to see her today.
Ever since then, she came over every time Min Sun was out of town.
Did anything happen?
Of course.
How was the meeting?
You know... same old, same old.
Did you know too?
What?
Min Sun stays at hotels every time she has a seminar out of town.
Is that important?
It's not like you guys married to have a family.
You married her for money and she for your reputation.
And I'm doing this because I love you-
She's a scary woman.
If you're that curious, go ask her yourself.
It's not like you didn't like it.
What?
Let's end this.
All of a sudden?
You used to like it.
Look how far you've gotten since we first met...
We cannot divorce.
Not yet...
That was the end.
From that point on...
We were just married on paper.
I purposely acted more close with Hyun Joo.
But she didn't care.
I also want to know what their relationship was.
I've never heard of friends sharing their husbands.
He calls her by her name. Min Sun calls him "oppa."
The names are all consistent on the statements.
The handwriting analysis shows that it doesn't match with the photo.
He might've tried to rationalize the affair but...
He's not the criminal.
Then, what is it?
It's not a mixed affair...
And it's not friendship.
I am...
What could it be?
Dictionary...
I am? I am...
I am...
Cute?
I guess I am kind of cute.
Murderer...
Murderer?
What are you doing here?
What the heck!
You can't just leave a mess because you're investigating!
It was here.
Have you seen this picture before?
Of course!
Was it 6 months ago?
Just from looking at this picture?
That's what I'm saying!
She turned pale and because a different person for days.
She didn't smile and never came out of her room!
I put the rest of it somewhere...
Geez, she's so picky.
She throws it away and then gets mad at me later.
The rest?!
Oh no!
I think I put everything inside the envelope and threw it out.
It was just here! They must've already thrown it out.
Stop!
Wait! Stop!
Police! Stop!
What's that smell?
I found it.
I am back.
I am back?
What could this mean?
This girl has the answer.
Director, we found her identity.
Residence in Po Chun, age 33. Name is Im Se Jin.
But the thing is...
She's already dead.
Dead?
6 months ago, a body was discovered at the fire scene.
The body belonged to Im Se Jin.
After living in America, she moved back to Korea near Po Chun.
The criminal set a fire to get rid of all the evidence.
All her valuables were there and there were no signs of sexual assault.
The only thing left were the footprints found at the scene.
And...
This.
June 29th?
The victim left a dead sign.
They tried to track down this date with related events and people.
But they couldn't find anything.
So it was left unfinished?
Not anymore.
This picture showed us the relation between the two cases.
Kim Min Sun started taking the tranquilizers 6 months ago.
It matches with Im Se Jin's death date.
Oh Hyun Joo received this photo 6 months ago as well.
So...
Kim Min Sun and Oh Hyun Joo probably knew who the murderer was.
Why didn't they report it?
Serial murder?
I am back?
This is a treat.
In the end...
He murdered all three people.
The murderer wanted to get rid of this photo...
...because he didn't want us to know the relation between the two cases.
The guy who Kim Min Sun called "you"...
...sent this picture to Oh Hyun Joo...
...and tried to leave a mark on June 29th.
The murderer is connected to all three women.
Im Se Jin didn't keep in touch after she immigrated to America.
So the connection started 15 years ago.
Even though they were all born in Bu Chun and went to the same schools...
There was no special case between the three of them.
They all separated in high school.
Therefore, the connection ended there.
Wait.
There's something strange about their high schools.
Myung Il High School...
Gang Jin High School... Hyo Shin High School.
All the high schools are far from where they live.
That's right.
Why did they attend schools in different districts?
Far away and all different...
Kim Min Sun and Oh Hyun Joo knew the criminal and...
Im Se Jin marked the 29th to point at the murderer.
If the criminal was related to the 29th...
Kim Min Sun and Oh Hyun Hoo must've had meaning to that date as well.
But on their phones...
...only June 12th and June 26th was marked down.
What do these dates mean?
2 weeks and 3 days...
What?
The days in between those 2 marked dates.
Director.
All three came from the same high school.
But for some reason, they all transferred to different schools.
Even hiding the transfer records.
The connection happened right there 15 years ago.
15 years
Do you remember these 3 girls?
Of course. They were popular.
Popular?
They were the 3 princesses. They had everything.
Their families were well off, they were smart and plus, they were pretty.
They were so great that even the teachers didn't say anything.
Was there an accident?
They were murdered.
Our only clue is the connection between these three victims.
Do you remember why they transferred 15 years ago?
There was a strange student named Park Soon Young.
Even though she was a bit strange, she was still a nice kid.
That made the kids bully her more.
Only our class had a male teacher.
He was popular because he was tall and handsome.
Okay!
Who wants to help me after class today?
I'll buy you instant ramen!
Me!
When those girls volunteered, nobody bothered to join in.
For some reason, Soon Young raised her hand.
Okay, Soon Young can help me.
A few days later...
It was gym class.
She just took a wrong step.
What does that have to do with these three girls?
These girls were the only ones left after class.
There were 4 girls and one fell off and died.
The three girls then became both witnesses and suspects.
Even if they were the criminals, they wouldn't have testified.
Unless they confessed themselves...
...the case would never have been solved.
I tried to stop her...
But it was too late.
Only if I was faster...
What the... If Soon Young was still alive...
I'd buy her 100 of those scarves.
She took a wrong step...
And then...
She simply took the wrong step.
All of their testimonies were the same.
They said Park Soon Young was trying to pick up her scarf.
Scarf?
She said it was a gift from her mom and wore it everyday.
If you want it that bad, come take it.
Give it back.
That's when I knew.
Nobody can be punished if the victim is already dead.
I still get goosebumps even after 15 years.
How could something like that-
Do you remember the date?
June 12.
My birthday was the day after so I remember it clearly.
June 12th is the day Kim Min Sun and Oh Hyun Joo were murdered.
It's also the day the statute of limitations ended for Park Soon Young's case.
I am back.
The murderer came back on the same day...
...to make them pay for what they did 15 years ago.
Director Yeo.
Park Soon Young has a younger brother named Park Joon Young.
They both grew up with their grandmother.
Shortly after Park Soon Young's death, the grandmother passed away.
Park Joon Young was sent to a foster home.
And then he became a fisherman.
If he was a fisherman, getting the globefish would've been easy.
He's a notable suspect for this case.
2 Weeks
Are you not going to try looking for it?
I'm having such a hard time.
The statute of limitations ended on June 12...
Then what happened on June 26th?
Maybe the statute of limitations ended on a different day.
The statue of limitations extends when you leave the country.
You didn't know?
But, Kim Min Sun had a fear of flying-
Was it 5 years ago?
You know that the bars closed down due to financial crisis, right?
The doctor lady solved all of our problems.
Around 5 years ago...
Oh Hyun Joo was always in our relationship.
5 years ago...
Where are you going?
I'm working my butt off.
How am I going to do this by myself?
I heard you found the criminal?
He's still just a suspect.
What did you want to tell him?
This.
I looked everywhere but couldn't find any needle marks on the body.
The criminal didn't use a syringe.
Is there another way to inject it without a needle?
Through the respiratory system?
What else do you want from me?
Can you tell me what happened 5 years ago?
What's the point in that?
The truth about your wife.
5 years ago, she was invited to present at an important lecture.
It was an honor for her to be invited at her age.
Will you be alright?
How are you going to get on the plane?
I'm going.
Min Sun!
I can't miss it this time!
Keep this a secret from Hyun Joo.
But Oh Hyun Joo found out.
Because of that, Kim Min Sun's case was delayed 2 weeks later.
Oh Hyun Joo has been using against Kim Min Sun for the past 5 years.
Oh Hyun Joo's statute of limitations ended but...
Kim Min Sun had 2 more weeks before her case expired.
This is the room that the customer stayed in.
Drinking and screaming all night...
Our customer complaints were no joke.
You were living in hell this entire time.
Not Kim Min Sun... but Oh Hyun Joo?
We examined the inside of the car and found traces of...
...tetrodotoxin on the seat and floor.
The criminal must've sprayed it.
The only reason a murderer would use poison is it's certain.
That means he was 100% trying to kill someone.
But he sprayed it on the floor...
The objective and method don't match up.
The car's air conditioner is broken.
Do you know this person? Park Joon Young?
Did he even look at it?
Did Joon Young, this bastard...
...cause trouble?
Is he the type to cause trouble?
He's a nice kid but when he drinks, he gets crazy.
I heard his sister died when he was young.
He used to cut himself...
Has it been 6-7 months now?
He disappeared all of a sudden. He even left his stuff.
Do you know where he went?
I shipped his stuff for him.
I think it was... Bong Chun?
Bong Chun?
Over here.
Park Joon Young?
Park Joon Young!
He suffered from kidney failure.
It doesn't mix well with alcohol.
Time of death?
Judging by the body's decay, probably 6 months ago.
He died between December 25-26, 2012.
He stopped writing in his diary on that date.
6 more months until the statute of limitations ends for my sister's case.
Her death was unfair.
Poor sister...
If only I had more strength...
I could've made things fair for her.
They don't have the courage to stab me.
Bastards.
Sis...
I'm sorry.
What is this?
Wait, if he died on December 25...
That means he died 10 days before Im Se Jin.
His death is unrelated to Im Se Jin's death.
Who killed all three?
It's not like a corpse came back to life to seek his sister's revenge.
Here!
The statute of limitations date was marked on his calendar.
He must've been mistaken.
Wait... if it was June 29th...
That's Im Se Jin's dead sign!
3 Days
Park Joon Young thought the statute of limitations ended on the 29th.
Im Se Jin left a dead sign on the 29th.
How did she know that he would think the case was closed on that date?
I am back?
Was he really mistaken?
Save me...
You... you!
How is that possible?
It's Yeo Ji Hoon.
Connect me to the police who received the call the day of the murder.
Yeh Ri, the results are out.
It's the same handwriting.
You were the one who sent it.
The hiking boots from Oh Hyun Joo's house match the footprints found at the scene of Im Se Jin's murder.
The handwriting on the back of the photo belonged to Im Se Jin.
Im Se Jin threatened Oh Hyun Joo.
She was trying to tell them that she was back from America.
Im Se Jin knew that Oh Hyun Joo was threatening Kim Min Sun.
She wanted to do the same thing.
Wasn't Im Se Jin gone for 15 years?
Looking at the statutory date, Im Se Jin had the most disadvantage.
There was nothing to lose.
She became bankrupt after 15 years of living in America.
When the case came up...
She probably thought that they had more to lose than she did.
During the 2 week gap, another person was murdered.
Not 2 weeks!
3 days! 3 days.
This is in America!
Oh Hyun Joo was in America from July 5, 2001 to July 22.
It didn't show up in her records.
It doesn't show up on the computers.
Her departure records somehow disappeared.
Like the way Kim Min Sun was hiding it, so was Oh Hyun Joo.
So!
Oh Hyun Joo was out of the country for 17 days.
Kim Min Sun for 14 days.
If Oh Hyun Joo's statutory limitation date extended...
It would've been on June 29th.
Im Se Jin's dead sign was pointing at Oh Hyun Joo!
How did you find this?
During the past 15 years, only 2 people never forget this date.
The person who wanted to end this case and...
...the person who wanted to keep extending the date.
Would Park Joon Young really have mistaken this date?
He would never miscount this date.
So did Oh Hyun Joo also murder Kim Min Sun?
Kim Min Sun murdered Oh Hyun Joo.
The crime date was June 12th.
The last day of the statutory limitation.
Jun 12th doesn't apply to any of them.
Only one person.
One person believed June 12th was the last day.
Kim Min Sun.
During the last 5 years, she lived under Oh Hyun Joo's threats.
Because her statutory limitation date was longer than Oh Hyun Joo's.
That's why they both wrote down the statutory limitation date.
So when June 12th came around, they both panicked.
Oh Hyun Joo's date expired but Kim Min Sun had 2 more weeks.
Since Oh Hyun Joo put her in hell, Kim Min Sun couldn't trust her.
And so!
If Oh Hyun Joo murdered Im Se Jin and Kim Min Sun murdered Oh Hyun Joo...
Who killed Kim Min Sun?
The criminal who was at the scene?
Doubts and fears...
This was the last puzzle.
Let's go. I found the real killer.
On the day of the murder, it was over normal summer temperature.
Plus, Kim Min Sun's air conditioner was broken.
Congrats. It's finally over.
You're keeping your promise, right?
You don't trust me?
Kim Min Sun took a large amounts of sleeping pills and tranquilizers.
While pouring the poison into the coffee, she accidentally spilled.
That's why the car seat had traces of tetrodotoxin.
The view looks great, huh?
Yeah...
Save me...
While Oh Hyun Joo was drinking the coffee, she rolled up the windows.
To maximize the effects of the poison.
But, even she underestimated how powerful poison could be.
As the car temperature got warmer...
The tetrodotoxin on the seat vaporized and she breathed it in.
At first, she had no idea that she was being poisoned too.
She probably thought it was because she was nervous.
So she threw away the evidence and went back to her car.
That explains the mud found on her shoes.
But she called too late.
So she died accidentally...
Right.
So who's the one who locked the door?
Right. Are you saying the real killer is around here?
During certain times of the day, the wind changes the direction of the sea.
It should show up soon.
That's what killed Kim Min Sun.
On the day of the crime, there was a banner.
Kim Min Sun thought it was Park Soon Young's scarf.
Save... me...
You... you!
Give it back.
She mistook the banner for Park Soon Young's scarf.
Because it was on her conscious for the last 15 years.
But how did she become mistaken by seeing that banner?
And they also mistook something else. That scarf-
It was white.
Like Detective Baek said, it's just an analogy.
It was just her conscious coming out.
But the fear in Kim Min Sun's face...
There's no other way to explain it except through this.
Every sin comes with a cost.
I'd rather her have seen Park Soon Young's face.
So...
Since everyone related to this crime is dead...
This case is closed.
I didn't know you were into baseball.
Why? Is it weird?
You don't look like you would like it but you do...
There'll come a time where everyone has to throw a breaking ball.
You'll throw a good one.
During Song Kyung Tae's trial...
The court failed to recognize one of the charges.
You mean Song Mi Joo's murder?
How long are the two of you going to keep avoiding me?
Director Yeo.
Let's talk.
Min Ho.
Yes?
It's going to rain tomorrow.
I'm going to die.
Director Yeo!
He was in his office the entire morning since dawn.
F. That's what it said.
I don't know why you're doing this...
But we can help you.
Director Yeo!
