(Characters and incidents used in this drama are fictitious.)
What's this? Suicide?
Mr. Seo would've never killed himself.
You can't rule out murder.
Redo the autopsy. I can prove it.
If you do that, it works against you.
I don't care.
You're performing the autopsy?
The body.
- It's not here yet. - Where is it?
Mister, mister. We need help.
You can't cremate number one just yet.
Can you stop the procedure?
(Episode 21)
Arrest him again.
The body was cremated.
- What? - The process has begun.
The body's all burnt.
How much of it was burnt?
We're from Seoul Eastern District Prosecutor's Office.
- Stop the machine. - Pardon?
This is the warrant that allows us to seize the body in there.
Turn off the power. Please do it now.
- What are you talking about? - Please turn off the power. Hurry.
Hyun, it's me.
I stopped the machine midway,
but it's all burnt.
- Okay. - Bring the body.
I don't think you understand what's going on here.
- It's all over now. - It's not over yet.
I can still perform the autopsy with a piece of the body.
- What? - A piece of a bone is enough.
What can you achieve with the half-burnt body?
I must perform the autopsy.
Don't you want to prove that it was a murder?
Hyun.
Transfer the body to the NFS.
All right then. Go ahead.
Get ready for the autopsy.
Did he really ask you to bring the body?
It's completely burnt. Will the body give him a lead?
Let's head over there for the time being.
By the way, what's wrong with Dr. Psycho?
If it turns out to be homicide, he will return to the detention center.
My goodness.
Start the car. Let's go.
- We should go. - Okay.
Prosecutor Kang, what do you think you're doing?
- I'm sorry. - Do you not trust me?
The autopsy is a part of the investigation.
And the investigation falls under my authority.
Then will he really redo the autopsy with the burnt body?
Sir, Dr. Baek will take a thorough look again.
Director, the tissues are all ruined from the first autopsy.
Besides, do you believe he can do an autopsy with a burnt body?
Do you think that will restore the burnt tissues?
If the protein gets denatured from the heat, it's irreversible.
You do have a point, but...
If you know, how could you allow this?
I can't find a reason to stay and watch this autopsy.
Prosecutor Kang, I'm pulling myself off this case.
Sir.
The body is here.
Current time, 2:16pm.
I'll begin the autopsy.
Wait, what happened? Did the body move?
His hands and feet didn't look like that after the first autopsy.
It's the pugilistic posture.
It's due to high heat.
The tissues in his muscles have been denatured.
Our muscles that get swollen up are more developed than other muscles.
That's why every muscle has become denatured to swell up.
Did that happen after his death?
The fact that muscles are made of protein is immutable.
- All of his hair is destroyed. - "All of his hair is destroyed."
- 90 percent of skin is ruined. - "90 percent of skin is ruined."
Will we be able to find anything?
Only his muscles are left. We can't see any external injuries.
I need blood. Blood.
Can I have blood, please?
Scalpel.
I think the organs are burnt as well.
I just need his heart.
Where's the heart?
Since it was situated in the inner part, it wasn't completely burnt.
Syringe.
Will there be any blood?
Come on.
Yes. Fantastic.
We can put this through LC-MS at least once.
(LC-MS: Liquid chromatograph-mass spectrometer)
One and only chance.
It's urgent.
Roger.
Show me the pictures from the first autopsy. Let me compare them.
Okay.
- There's no vital reaction. - What does that mean?
They cut off his nails after his death.
Nails leave the most evidence...
when one gets into a fight or comes in contact with someone.
That must be why they cut it off on purpose.
His nails probably scratched the culprit's body as he fell.
If the culprit cut his nails,
there could be traces left on the cut nails.
It's no use. His fingers are burnt.
Goodness. Only if we were an hour early.
Which is the first? The head injury or the injection?
Professor Pyo said the injection was first.
You have the result, don't you? What came first?
What is it?
I will refrain from judging until we have his blood analysis.
You're right. What can he find out with a body that's burnt up?
- Is the site preserved? - Yes.
A strand of hair and a piece of nail are all parts of his body.
Soo Yeon, go to the field.
- Yes. - I'll see you.
Ms. Cheon. It's me.
I'll text you.
Do you think we'll find a piece of nail that he clipped off?
The pride of National Forensic Service...
rests upon that piece of nail.
But we might find the nails which he clipped off himself.
How can you know which is which?
We can look into its components.
Old nails have a different level of water content.
We don't know where it could be,
- so please go through every inch. - Okay.
Hey, good to see you.
Jang Tae Joo stole succinylcholine a few days ago.
Give that to me.
And not just 1 bottle, but 3.
You can never tell what this idiot is up to right now.
He has yet another target after Mr. Seo.
Is there a possibility of his committing another crime?
Prosecutor Kang, this is a serial murder case.
Someone suspicious had been lurking around Mr. Seo as well.
Was that Jang Tae Joo?
He looks quite similar.
It looks like this was planned.
I'll write up a list of people that Jang might hold a grudge against.
Invalidate his passport immediately,
and put him on the most wanted list nationwide.
Let's take all the measures which we can take...
to find Jang Tae Joo.
Yes.
I'll go back to the office to form a team to arrest him.
Let me know when the autopsy result is out.
Okay, Hyun.
Keep tracking Jang and let me know how it goes.
All right.
- Lieutenant Cha. - Yes?
I'm sorry for everything.
You're back.
Prosecutor Kang.
What will happen to us if we don't find that nail?
If he clipped 1 nail 3 times, that makes a total of 30 pieces.
I'm sure we'll find one.
Found it.
His name is Park Byeong Goo.
He used to provide Jang with drugs five years ago.
He got locked up first, then ratted on Jang.
Thanks to that, he got his sentence reduced to two years.
That sounds like a good reason to hold a grudge.
We're here.
What is this?
Are you sure this is his place?
I am.
Do you think he killed him already?
Then we should at least see a dead body here.
Did something happen in this house again?
Pardon?
Who are you?
Young man.
I called the ambulance for the young man who lives here...
when he was about to die.
Stay with me.
The ambulance?
We performed CPR on him in the ambulance.
Then we left him on the bed, but he disappeared soon after.
I got the security footage.
Good.
There are many people who run away because they can't pay the bill.
No, he didn't run away because of money.
There is someone who can find his whereabouts.
Take a left here. No, take a right.
- A right? - Yes, to the right.
Go straight.
This place looks exactly the same. Go straight.
Are you sure we'll find something if we keep going?
Just keep going. Go straight.
That's all that you've been saying.
I can't believe this place.
This neighborhood hasn't changed a bit.
I can't believe it.
- Where are we going? - Just go straight.
Keep going. More.
Keep going. Yes.
Okay, that's it. Hey, wait. That's it. Stop.
Good job. We're here.
You'll see a person named Doctor Park up there.
She's the godfather of all druggies.
Say that I sent you two, and she'll know what to do.
- Hurry up and go. - Okay.
Come on, you know who Park Byeong Goo is.
Don't do this. We already know everything.
There's no one like that here. You're at the wrong hospital.
Come on, we both know what we're talking about.
I really know everything.
- Go. - What?
Okay, fine.
You don't seem to have a medical license.
Do you want me to do a background check on you?
Just leave, detective.
This place has more flies than patients.
All you'll find is fly dung if you run a background check.
If you continue being so uncooperative...
Article 317 of the Criminal Code.
"A doctor must not disclose..."
"any confidential information they obtain on their duty."
I guess detectives nowadays don't study law.
Did you get that off the internet?
I practically fed you, yet you still can't eat.
Darn it. It's him.
- Goodness. - Hello, Detective Kang.
Have you been well?
Doctor Park, you're the same.
No, you got prettier.
- Do you still do drugs? - Come on.
Don't say that.
Say hello to them. They're my juniors.
I really adore them.
And we're looking for someone.
Dong Sik.
I'll go out of business...
if I lose my credibility in this industry.
And your juniors are unbelievably rude...
Wait. Rude?
Are you trying to tell me...
that I need to do a better job in bringing my juniors up?
- It's okay. I'll get this. - Let go of me.
Doctor Park.
Guess why I let you be?
Drug addicts.
They need help when they're sick or hurt.
I can't let them die in the streets because they can't go to a hospital.
But then, I can't let my juniors...
see me let you off, can I?
How about it? It's been a while.
Shall we have some fun?
Okay.
Fine.
(Room 302)
I didn't say a word.
Right?
He strangled me, then I felt a poke from behind.
My reflexes took over and I flipped him over my shoulder.
I really thought I was going to die.
Do you mean he may have a grudge on someone else too?
Well...
The thing is...
Mr. Kang, we identified Jang Tae Joo's next target.
It's Prosecutor Do Ji An.
He was the one who apprehended Jang Tae Joo with Mr. Seo.
What?
He killed Mr. Seo first,
then tried and failed to kill the snitch.
Now he's after Prosecutor Do.
He just got back from an overseas business trip yesterday.
I'll send an arrest team over now.
Do you see the peaks? It's not just for SMC.
We even got SUX.
Fantastic.
What? SUV? Fantastic?
What's fantastic?
It's SUX, not SUV.
Listen carefully.
Every drug, once it enters a body,
enters the bloodstream and reacts with enzymes to metabolize.
In the blood, we find metabolomes, the result of metabolization.
So called the miracle of metabolism.
Can't you just tell us the conclusion?
Okay, cool.
The metabolome of succinylcholine is called SMC.
When succinylcholine, SUX, enters a body,
it turns into SMC.
But in Seo Jeong Min's blood,
we didn't find much SMC.
We found more of the original SUX.
Metabolization didn't happen much.
Why is that?
He was already dead.
Bingo.
Metabolization stops with death.
Rapid degradation.
The order of damage is...
Scalp hemorrhage.
(Bleeding from torn scalp)
Linear fracture.
(Fracture in a straight line)
Subdural hemorrhage.
Injection after death.
Type of death, homicide.
The succinylcholine and sodium pentothal were injected after death.
To cover it up as suicide.
We found nothing on the fingernail.
We tested the water content and it's over a week old.
Whoever the killer is made sure to take everything.
(Kang Hyun)
Eun Sol speaking.
Okay. I'll go to the office right now.
They identified Jang Tae Joo's next target.
- Let's go. - Okay.
Doctor, take a break.
We just need to catch him now.
We brought all this dust for nothing.
It'll take ages to clean up.
(Crime Scene Report)
The scene was clean? No finger or footprints?
Just the living room. The other rooms were filthy and dusty.
It was cleaned up?
- Yes. - And evidence destroyed.
Where's the tape?
- What do you need it for? - Get it.
Just a moment.
- Hello. - Who are you?
Are you surprised?
Darn you, now I need a tetanus shot.
Come here. I can give an injection too.
What?
What's wrong? Get up.
He got away. Get him.
Where do you think you're going?
Come on.
Let go. Let go of me.
Jang Tae Joo, you're under arrest for the murder of Seo Jeong Min.
- What? - And attempted murder of...
Park Byeong Goo and Do Ji An.
Get up!
Let's go.
Jeans and hoodie. 182cm tall.
285mm shoe size.
This is you.
So is this.
You dare attack a prosecutor's investigator?
Someone like you?
Have you ever seen the face of death?
It's thousands of times more addictive than any drug.
What?
The barkers.
Dogs.
A shot of succinylcholine is all it takes.
I should've just shot him.
Doctor.
Look at this.
The Prosecutor's Office.
- What? - I need to be there.
Doctor.
Put me through.
- What? - It's urgent.
Okay.
Here you go.
It's not him.
- What do you mean? - He's not the killer.
What?
Why isn't it him?
What's going on?
What's that?
A piece of tape found on the floor of Mr. Seo's home.
The crime scene there.
Do you remember how the floor was spotless?
Yes. You found nothing there.
He used that.
That's why we found nothing?
We found the tape.
If you see here, the torn edges are uneven.
It was ripped by teeth.
Saliva contains DNA.
Then we can compare that to Jang Tae Joo's.
- There's no need. - What are you talking about?
It's a woman.
We also found substances of lipstick in the saliva.
The murderer is a woman?
- What? - What? A woman?
But Jang Tae Joo stole the drugs.
We have him on the dash cam footage.
Two people went into that house that night.
The first one is the real murderer who is a woman.
The second one is that jerk.
Darn it.
You're saying that...
Mr. Seo was already dead when he walked in.
Then who is the real murderer?
Prosecutor Kang.
Mr. Seo's call history for the last three months.
Thanks.
(Call history)
(Abduction Case)
I think I know...
who the real murderer is.
I...
omitted a part of his call history.
