(Characters and incidents used in this drama are fictitious.)
No exact time of death, right?
The curtains and the heater accelerated the decomposition.
There's no way...
a killer would've taken off his shoe and left it.
This pair. Where's the other shoe?
You must come with us now.
(Episode 9)
I haven't told him anything just as you instructed.
You brought your phone with you, right?
- What? - Give it to me.
The other one.
You have one more.
Unlock it.

(Yeon Mi Rae)
May I ask what...
this is regarding?
Do you remember...
Ms. Yeon Mi Rae?
Yeon Mi Rae... Yeon Mi Rae...
Yes, yes. I do remember her.
I think it's been about a year.
She sued a delivery man...
for stalking her. Yes, that's it.
- After that? - Well...
The guy was put on probation...
- and had to do community service... - No.
- I'm asking about Ms. Yeon. - What?
I'm sure she's doing fine.
- Haven't you been seeing her? - What?
Why would I meet someone who's involved in a case?
What were you doing last night?
It was my day off yesterday.
I had a drink at home,
- then slept. - Were you all by yourself?
Yes.
But why? Did something happen to Ms. Yeon?
Why are you lying?
You met...
(Yeon Mi Rae)
Ms. Yeon.
I lied because I didn't want to cause any trouble. I'm sorry.
Well, Prosecutor Eun.
It really seems like he has no idea.
What? What is it? What do I not know?
- Please. - What?
Lieutenant Cha.
Ms. Yeon was...
found dead.
You're here as a suspect.
What?
What did you just say? Found dead?
Are you saying Mi Rae is dead?
Dong Sik. Is this...
It's not me. I didn't do it!
- Please, Soo Ho! - Dong Sik.
Please.
Prosecutor Eun, we need his blood sample.
My blood?
You reek of alcohol right now!
Yes, all right.
- Go ahead. - What? Go ahead with what?
Hey.
What?
- Dong Sik. - Oh, my. Excuse me.
Deputy Kang, what's going on?
Why is he a suspect for murder?
- What? - Gosh, darn it.
Isn't it odd?
He's been using two cell phones,
- and he lied about not meeting her. - That's his habit.
He cheats on women all the time, so he didn't want to get caught.
So he's careful.
Prosecutor Eun, are you suspicious of Lieutenant Cha?
- Stop it. You're jinxing this. - I just...
- Darn it. - Goodness.
Hey, one second.
What happened?
Dong Sik, something has gone completely wrong here.
- I didn't do it. - Then why on earth...
What is it?
Will you give us a second?
Let me talk to him, okay?
Tell me the truth.
- Is it really not you? - It's not.
Dong Sik.
You trust me, right?
Yesterday, I just had a drink and fell asleep.
Do you remember everything?
Well, I... I was drinking yesterday, then...
Then I... Well...
You idiot. You must be insane.
Come to your senses,
and look straight into my eyes.
Did you do it or not?
Darn it. Who is it?
What is this?
Blood?
I'm not really sure. I can't remember.
You crazy idiot. How much did you drink?
I don't know.
I can't remember much...
from yesterday night.
Dong Sik, help me. You have to help me. I'm scared.
Please, Dong Sik. I can't.
Please help me. I didn't...
- What have you done? - I didn't do it.
- Calm down. - Let go of me!
And you.
You're his senior.
How can you tell me to calm down when your junior is like this?
I'm frustrated as it is too! I'm just here to...
- It's driving me crazy too. - Forget it!
You idiot. Seriously.
You.
Make sure you do everything right.
And stop crying!
My gosh.
My goodness.
Decomposition is the enemy of forensic science.
Measuring stick.
Things that were in the body begins to disappear,
and things that weren't appear.
That's the birth of a lying corpse.
Cutting wound number 3, 2.3cm deep.
"Cutting wound number 3, 2.3cm deep."
- How many times was she stabbed? - 16 times.
This had to be a grudge over a romantic relationship.
- It's too much. - You're right.
Let's get back to work.
Yes, sir.
The blade was on the top. Was he holding it upside down?
No.
(Cutting wound: A wound created by a sharp cut)
- Let's turn her over. - Okay.
(Partners for Justice)
(Open Wound: An opened wound caused by a stab or a cut)
What do you think?
She died from suffocation due to pressure.
And she was strangled.
- Strangled with hands. - But he stabbed her 16 times.
None of the wounds were critical.
He toyed around with her while stabbing.
And she was also hit on the face.
Her face decomposed quickly...
because she bled a lot.
Flies usually lay eggs in open wounds with blood.
- Maggots. You remember, right? - Yes, sure.
So who is this suspect that you said we know?
Lieutenant Cha Soo Ho.
Good.
- What? - I won't see him for a while.
How can you say that?
She was obviously murdered.
You were always so considerate of the victims.
Now that you know the suspect, do you not care about the victim?
What about you? You care nothing about the pains of the victims.
I need to think like a suspect when I perform autopsies.
That's how you can figure out how their bodies were damaged.
If the culprit stabbed her that much,
isn't it a crime of passion?
You usually do see many open wounds...
- in cases with serious grudges. - Don't jump to conclusions.
And...
Never mind. Forget it.
Wait. Dr. Baek.
- Hello. - Hi.
Do you have anything?
We're collecting evidence to compare to what we have.
- He drank a lot... - Get to work!
Are you wearing gloves?
- We are. - Yes.
I'm done.
- You're done? - Yes.
- Were you thorough? - Yes.
Step aside.
What's this?
- What's that? - "What's that?"
Covering up on site.
Shall I recite the manual?
- I saw... - Shall I recite it?
- Sorry, sir. - Pack it up.
Pack up.
What are the security cameras for then? Accessories?
Why are you yelling at me? I just man the office.
How long were they broken for?
For a few days.
The whole server was wiped out.
The repair guy's coming next week. It breaks down often.
We have nothing on that night.
This is driving me insane.
Let's meet the reference witnesses.
Kim Joon Tae, 22.
Yeon Mi Rae's boyfriend of three months.
Mi Rae...
I miss her so much.
It's hard, I know.
It doesn't feel real.
Her not being here...
A funeral is a tough thing to manage.
My condolences.
Before her death,
did you notice anything odd or out of the ordinary?
I was studying for an exam,
- so we didn't meet often. - What about the day she died?
I was at the library.
I should've forgotten about...
the exam to stay with her.
It's my fault. This is all on me.
Did she...
recently tell you about any concerns...
or worries?
That stalker.
That bothered her a lot.
She would jump and tremble whenever her doorbell rang.
She'd say she was too scared to go home alone,
but I didn't walk her back.
The courier who stalked her?
Yes.
(Seok Do Hoon, courier)
Courier Seok Do Hoon, 25.
Sentenced to community service for stalking.
Did you hear about Yeon Mi Rae?
Who's that?
You're asking us?
You stalked her for months and broke into her place.
You don't remember?
Oh, her?
She's the reason I'm in this mess.
Do you remember her?
- So what? - You don't know?
The trial about how I stalked her is over.
You don't take me seriously because I'm a courier,
but she was interested in me too.
Why else would she smile and give me coffee...
- when I came over? - Okay.
You can dream all you want.
But stalking is a crime, okay?
You must've hated her.
To be honest, I was utterly shocked.
- I don't care what's going on... - She was murdered.
Poor Mi Rae.
What?
She's dead?
Are you suspecting me?
What did you do on May 27?
May 27?
I played games at an internet cafe.
An internet cafe is a clear alibi.
Please check the time he logged in...
- and the security cameras. - Sure.
(Temperature at scene: 28℃)
Door closing.
Wait for me.
Sorry...
Going up.
I guess you're coming back from work.
No private conversations.
You must be the assailant during the autopsy.
Do you get that?
Mom.
Miss, I need some water.
(National Forensic Service)
(Chain of Custody)
This is a mess. What will we do about Lieutenant Cha?
We shouldn't treat him like this.
What, then?
Should we blow up all the evidence?
That stupid idiot.
(Cha Soo Ho)
It's just too strange.
The blood stains on the wheel are Yeon Mi Rae's.
Her hairs were also found among those from the passenger seat.
The same goes for the blood on the towel under the driver's seat.
The towel was the same kind we found at the victim's home.
Get to the point.
The shoe we found at the victim's house...
had Cha Soo Ho's DNA.
(DNA Report)
(A match with Cha Soo Ho's DNA)
DNA?
We find a lot of dead skin cells from the wearer's feet and socks.
That's one more for your list.
Do you really believe Lieutenant Cha murdered her?
I looked through his phone.
His wallpaper for his phone was a photo of his badge.
He was serious about his career. He wouldn't do something like this.
Do you know that well what goes through a criminal's head?
You know those families who weep for their dead children?
I sometimes find signs of domestic abuse during autopsies.
Their stomachs are empty, and their bones are broken.
- They've been bleeding for long. - How long have you known...
Lieutenant Cha?
- Has it been about three years? - Do you believe that the man...
you'd known would do something like this?
My opinion isn't important.
He wouldn't kill someone. Can't you see that?
How can we believe anything a guy who can't remember said?
All the evidence is pointing toward Lieutenant Cha.
I usually had suspicions while having not enough evidence.
Never the vice versa.
It looks like... It looks like a perfectly completed puzzle.
That's why this seems even more suspicious.
Then find a piece that no one can plant into the puzzle.
What?
- What's that? - I don't know.
What is he talking about?
A shocking incident where an active cop was involved in the murder...
of a college student has taken place.
Cha, a detective in Violent Crimes of Gangdong Police Station,
approached the plaintiff of the case he was in charge of.
They already got wind of this.
Prosecutor Eun.
This can't be.
- I heard you wanted to see me. - Yes, come take a seat.
- About Lieutenant Cha's case... - Yes.
You should take over.
Have a press conference with the reporters this afternoon.
Sir, this is my case. I can do this.
Deputy Chief Kang, what do you think?
I'll take over, sir.
Prosecutor Eun worked closely with Lieutenant Cha...
for the cases she had taken on so far.
She might lose objectivity.
I've been investigating objectively, and I've been objective for this...
- Prosecutor Eun. - Yes, sir.
Do you know why our division is...
also known as Criminal Division 18?
Prosecutors, investigators, clerks,
and even the cleaning staff.
There's a total of 18 people...
who work at our division.
Don't try to stand out.
Then...
please let me join the investigation.
I won't try to stand out,
and I'll help the deputy chief.
I'll investigate...
with Prosecutor Eun.
This is an interesting mix.
This is a press conference...
regarding the college student murder at Cheonghong Officetel.
We have found out that A, who was apprehended as a suspect,
was the detective in charge of the victim's lawsuit against a stalker.
We have found out an active-duty cop was involved in the incident.
We're trying our best to obtain evidence to prove his involvement.
And a thorough investigation is being carried out.
We will reveal the whole truth...
through an investigation that's not tied to social status.
(Prosecution)
I'm Prosecutor Kang Hyun from Seoul Eastern District.
- Are you Cha Soo Ho? - Yes.
You're aware of why you're here, correct?
Sir.
I really didn't kill her.
It's... It's true.
Your blood alcohol concentration was at 0.3 percent this morning.
The night before,
- you must've been wasted. - I only slept at home.
Are you certain?
What? Blood?
Yes, I think so.
You "think so"?
Do you remember or not?
To be honest,
I'm not sure.
You forced the victim to date you with the information...
you acquired while investigating your case.
Are you aware that the nature of the offense is quite grave?
- Forced? I didn't do such a thing. - Why did you meet her then?
We restored all the messages and the call records.
You met 5 or 6 times after she filed against her stalker.
And you met her again 2 or 3 times recently. Isn't that right?
That... That was...
She was scared to death. I only met her to comfort her.
She didn't have any family members in Seoul either.
You should've only comforted her. Why did you kill her?
What do you mean?
I'm telling you. I didn't kill her.
- You're lying. - What?
If you didn't do anything to her, why did you wash your hands?
You washed off Yeon Mi Rae's blood!
We only checked the basin during the initial investigation.
We went back and checked the sink afterward.
We found the victim's blood there.
(Blood Report)
(99.7 percent likely that it matches with the victim's.)
That... That...
When I woke up, I had blood on my hands.
I washed it off without thinking much.
I don't know anything about this.
Sir.
How could I kill someone?
I really didn't do it.
I... I really didn't do it.
It wasn't me. I'm telling you the truth.
Sir, please.
Please! I didn't do it.
I can't believe you.
You startled me.
- What are you doing? - What do you mean?
You didn't find anything odd about the corpse?
Usually, you show up right about now...
and present new, critical evidence.
What evidence? Did you give me one to keep?
Do you not care if Lieutenant Cha is convicted of the murder?
My gosh, you're heartless.
You worked with him for three years. How could you be so heartless?
Just be honest.
Admit that you're not interested because this case is too obvious.
Gosh, I was surprised to think that a corpse lover...
like yourself was taking care of a pet.
So you didn't find anything that raised your suspicions this time?
Get out.
You are supposed to say that you can't believe everything you see...
then incise, take photos, and dig out stuff from the bodies.
This case isn't fun for you, right?
What? What is it? What are you keeping in here?
My gosh!
