Mr. Qi,

looking for something?

Why isn't this cabinet locked?

That one was broken long ago.

It wouldn't close.

So we didn't use it.

So Ding Youmei

is Gao Huilan's daughter.

You see,

the photo in uniform is of Liu Yuanyuan.

And Ding Youmei has a mole between her eyebrows.

The two

look identical,

except for that mole.

Could one have had

cosmetic surgery after growing up?

I suspect an exam proxy.

Exam proxy?

Yes.

Are you saying Liu Yuanyuan was

Ding Youmei's exam proxy?

Yes.

Wan and I checked on Ding Youmei.

Ding Youmei's grades had been

among the lowest.

But she scored exceptionally high

on that year's TOEFL

and went to study abroad.

But Liu Yuanyuan,

who always performed well,

missed the exam she was supposed to take.

There must be a reason

she missed the exam.

Could it be that

she took the TOEFL for Ding Youmei,

which affected her own exam?

The exam papers are

probably gone now.

Let's check if that exam

provides any other leads.

Okay.

Say Liu Yuanyuan had the evidence

of Gao Huilan and her daughter's

exam proxy back then,

and kept using it to threaten them

over the years.

And in the end,

having had enough of it,

they killed her.

But Liu Yuanyuan

was holding the knife at first.

Maybe Liu Yuanyuan

wanted to kill her,

but got killed instead.

Xi, play the camera footage.

The footage shows

that Liu Yuanyuan

left Gao Huilan's lab

after staying for 15 minutes.

Any other angles?

No.

Only one camera in the new lab building.

Xi, rewind it.

Okay.

Play it again.

See?

A black plastic bag

in her hand now.

She went in without concealing herself.

But coming out,

she kept covering her face

on purpose.

Suspicious.

Ding Youmei works there.

She should know

the location of each camera

in the university.

The video's so dark.

How can we be sure that

the person in the video

is Liu Yuanyuan?

Maybe Ding Youmei disguised

herself as Liu Yuanyuan.

If that's the case,

if this person was really

Ding Youmei in disguise,

then the thing in that

black plastic bag...

Found the record of Gao Huilan

paying Liu Yuanyuan.

No, wait.

I checked

Liu Yuanyuan's bank account.

Nothing unusual.

The bankbook is under

her mother's name.

Aside from

the recent transactions,

do you remember

the old bankbook

we found in her dorm room?

It was also under her mother's name.

It shows that

the earliest remittance

was eleven years ago.

Also, another key info.

That year,

the TOEFL and

the college entrance exam were

on the same day.

Eleven years ago,

when Liu Yuanyuan

missed her exam.

Yes.

Strangely, however,

Gao Huilan

also transferred a big sum

to a person named Luan Fang

besides Liu Yuanyuan.

I checked on Luan Fang.

She was Ding Youmei's classmate.

Also,

she and Ding Youmei were in the same

exam room back then.

Look into Luan Fang.

Okay.

Call in Gao Huilan and

Ding Huimei, too.

Okay, I'll go.

We already

talked to Luan Fang.

She said

she saw Ding Youmei back then.

Youmei?

Why are you here?

Aren't you taking the TOEFL?

Luan Fang recalled Ding Youmei saying

she'd take the TOEFL.

So she was surprised to see Ding Youmei

at the college

entrance exam that day.

The college entrance exam that year

and the TOEFL Ding Youmei took

were on the same day.

How could she

attend two different exams at the same time?

You should know

the answer to this question.

Did Liu Yuanyuan

take the exam for you?

Yes.

But it was my mom's arrangement.

I was very young back then.

I'd do whatever she said.

That afternoon, six days ago,

did Liu Yuanyuan

go to the lab for you?

She did.

Yuan came to the lab for me.

Was Ding Youmei also there?

They had an argument.

What did they argue about?

Even if you don't tell,

we will figure it out.

Everything I did

was for

my daughter's future.

Because of what happened back then...

What happened back then?

Back then, I gave

Yuan's mother

free surgery

so she would take

the exam for Youmei.

I did save Yuan's mother's life.

But for these eleven years,

she kept threatening us

with this secret.

What about the remittance record?

They kept threatening us

with the exam proxy,

blackmailing us for money all the time.

So all these years,

your mother's been

sending Liu Yuanyuan money

because of the exam proxy.

That's why

you killed her,

swapped the body,

and ditched it.

She kept hurting us.

After Yuan's mother died,

she kept contacting me.

But I didn't reply.

So she came directly

to the lab for me.

Gao Huilan!

My mom's dead.

You killed her!

Your mom's dead?

How? What happened?

You know exactly

what happened.

It was your fault!

No.

Listen,

why would I harm your mother?

I would never do that.

You know what condition

your mom was in.

If I hadn't save her life with surgery

eleven years ago,

she'd have been long gone.

Yes.

You saved her life back then.

But also because of you,

my mom's dead now,

and my life is ruined.

It's your fault.

It's all your fault!

Yuan,

listen to me.

That's no way...

No way I'd harm your mother!

Stay away!

I'll kill you!

Calm down, Yuan.

I didn't kill your mother!

Calm down!

You killed her!

That day,

I heard my mom was

arguing with Liu Yuanyuan

in the lab.

So I ran over in a hurry.

When I opened the door,

Liu Yuanyuan charged at my mom

with a knife like crazy.

So I rushed over immediately!

Yuan!

Yuan!

Yuan!

Yuan!

You killed her!

Yuan,

listen to me now!

No...

Yuan!

Liu Yuanyuan! What are you doing?

I also fell later.

Right,

this bruise

is from when I fell.

And then?

Yuan's mother passed away.

She felt hurt.

I could understand.

For years,

she had been miserable

due to her mother's illness.

I can relate.

I understand everything Yuan did.

Yuan?

Yuan, it's fine.

Are you okay?

Though your mom's gone,

you still have me.

I'll help you.

You can start fresh now.

No one can help me!

No one can...

No one can help me...

Nobody can help me...

No one can help me...

No one can help me now...

It's fine.

Don't be afraid.

I'll help you.

I'll help you.

Later, she left after

crying for a while.

Why didn't you tell us

last time?

You asked me if I went

to the specimen room last time.

I didn't know Yuan's case

was related to the specimen room.

I've told you everything I know.

Since that day,

I have never seen

Liu Yuanyuan again.

If you don't believe me,

go check the camera footage.

See exactly when

Liu Yuanyuan leaves.

You're familiar with how surveillance

cameras work, right?

Officer,

I don't know what you mean

by that.

Is this person you in the photo?

It... It's not me.

That's Liu Yuanyuan.

I know we looked alike

when we were kids.

But I had cosmetic surgery after growing up.

We don't look alike anymore.

Are you so sure

she is Liu Yuanyuan?

These clothes and the bag

are exactly the same as those

she had at the lab that day.

It's... It's really Liu Yuanyuan.

Did you ask Ding Youmei

to leave disguised as Liu Yuanyuan?

It all has to be based on evidence.

Do you have evidence?

Yes,

I asked Yuan to take the exam

for Youmei back then.

But I've been

regretting doing that.

It was a mistake.

But after Yuan left that day,

Youmei and I

stayed in the lab.

We only left at noon the next day.

Which body donor did Gao Huilan

borrow that day?

The register form shows No. 4.

Let me check her autopsy

record that day.

Okay.

An anatomy record.

Routine abdominal anatomy.

Demonstration of

rib fracture and lung lesion resection,

and observation of symptoms

of mitral valve prolapse.

Look.

Any problem?

Turn him over.

Other camera footage from the university

verified Gao Huilan's claims.

They did leave

the building the next day.

Only scenes of Gao Huilan and Wu Min

transporting body donors in between.

We don't have any evidence to prove

that Ding Youmei

and her mother are

related to Liu Yuanyuan's death.

We checked

every camera.

Liu Yuanyuan left the lab,

walked out

of the university.

And then disappeared?

We can't trace

her last whereabouts.

The surveillance cameras

in that area are all

from years ago.

The images are very blurry.

We can't distinguish

whether it's Liu Yuanyuan

or Ding Youmei.

We must find

more evidence.

Liu Yuanyuan bought bleach,

gloves, and black plastic bags

at the nearby grocery store.

And also a knife.

Back then, I gave

Yuan's mother

free surgery

so she would take

the exam for Youmei.

I did save Yuan's mother's life.

But for the past eleven years,

she kept threatening us

with this secret.

She kept hurting us.

That day,

I heard my mom was

arguing with Liu Yuanyuan

in the lab.

Liu Yuanyuan charged at my mom

with a knife like crazy.

So I rushed over immediately!

Maybe

Liu Yuanyuan wanted to kill her,

but got killed instead.

The fatal injury was inflicted by a hammer,

with a contact area

of eight square centimeters,

striking the right side

of the skull.

Our preliminary assessment

is that the weapon was a medical hammer

of this type.

The wire mesh opening

that you and Wan found on the hill

behind the lab,

what if it weren't

the killer's escape route,

but the way back?

Say it was Ding Youmei

who left the lab building

disguised as Liu Yuanyuan.

And she passed by

the cameras

at the lab building and the school gate on purpose

to create the illusion that Liu Yuanyuan

had left He City Medical University.

After ditching the head,

she could come back through the wire mesh opening

to return to the university

without being captured

by the camera at the gate.

If that was the case,

that could explain

why the cameras

didn't capture her when she returned.

But how did she return to the lab

without being filmed by the camera

at the lab's door

and walk out of it

the next day?

Keep looking.

See if there's anything that

supports our inference.

Gao Yuan.

Tweezers and bags.

Alright.

Any new discovery?

Here.

It seems to be

some kind of fiber.

More here.

What is it?

Human tissue.

But we checked

the body donor just now.

No scratch marks were found.

Because they didn't come from him.

It's a mortuary cabinet.

What else could it be?

There was supposed to be

another person with Gao Huilan on the day

she went to borrow a body donor.

She had a student called Wu Min.

Wu Min said Ms. Gao was

afraid she'd fail the test

and called her over alone

to give her extra lessons.

Xi and I went to ask

the security guard.

Same as Wu Min's story.

In medical schools,

anatomy is taught

in group sessions

held in the anatomy lab,

rather than moving

body donors between rooms.

Are you saying she moved

the body donor on purpose?

When moving body donors,

they're usually put in body bags.

That's a protection for them.

Meanwhile,

it's the best disguise.

That means

Liu Yuanyuan's body

was transported

into the specimen room

along with the body donor.

But if there were two bodies

in one body bag,

couldn't the student tell?

Unless the student was an accomplice.

Mr. Qi,

the results are in.

Accomplices have been ruled out.

Gao Yuan and I

went back to the specimen room

for another survey.

Clothing fibers and human tissue

from another individual

were found in the mortuary cabinet 4.

The fibers have been confirmed

to be from

Liu Yuanyuan's coat.

And the human tissue has matched

the third party's DNA sample

extracted from the coat.

So it was Ding Youmei wearing

Liu Yuanyuan's coat.

Exactly.

Gao Huilan was lying.

Liu Yuanyuan never

left her lab alive.

Ding Youmei didn't go right back

to the lab after she

buried the head,

because she knew

the camera would have

captured her.

Therefore,

she moved the body donor from cabinet 4

to the unused cabinet 5

and hid herself

in mortuary cabinet 4.

When Gao Huilan and Wu Min

came to borrow the body donor,

she could avoid the cameras perfectly

and return to the lab.

So what Gao Huilan transferred

wasn't a body donor,

but Ding Youmei.

She also found a student

who was scared of the bodies.

That's why no one noticed.

Ding Youmei was transported

back to the lab,

pretending to be a corpse.

Meanwhile, Gao Huilan

completed dismembering

Liu Yuanyuan's body overnight

and had Wu Min

send the body donor

back to the specimen room.

Except it wasn't

a body donor

this time,

but Liu Yuanyuan's

body fragments.

Everything makes sense now.

Gao Huilan returned to the specimen room,

put Liu Yuanyuan's body fragments

into the specimen jar.

She swapped Liu Yuanyuan's body fragments

and specimen body parts,

and further treated

the specimen bones,

then ditched the body parts

to create the illusion of multiple victims.

But in fact, the body donor in cabinet 4

had never left

the building.

It was moved

into the unused cabinet 5.

After that,

all they needed was to find a chance

to put the body donor back in cabinet 4

and complete the entire criminal process.

So all we need to do

is extract Ding Youmei's

DNA sample

and confirm that

she was the one in the mortuary cabinet

in Liu Yuanyuan's coat,

and we can close the case.

We found massive traces

of Liu Yuanyuan's

blood in your lab.

That was the scene of her death.

We extracted

your daughter's DNA

from both

Liu Yuanyuan's coat

and mortuary cabinet No. 4.

The evidence is solid.

Anything else to say?

It was all me.

My daughter wasn't involved.

She only did what I told her to do.

Then why did you

kill Liu Yuanyuan?

I did it for her own good.

Yuan was a good child.

She took the exam

for Youmei back then.

Yes.

She helped Youmei and me.

But we also helped her.

Dr. Gao,

the patient in bed 17

is quite stable this morning.

But the patient in bed 19

is having chest pain.

You'll have to check

on the patient later.

Okay.

Dr. Gao!

Youmei.

Dr. Gao.

Youmei?

She's not your daughter.

She does look like her, right?

Yes.

What's this girl

to the patient in bed 17?

She's her daughter,

a very filial girl.

I heard she's also a good student,

top three of the grade.

She's having it rough,

doing her homework here every day.

She's only a child, but she needs

to take care of her mother.

I feed you

and shelter you.

I give you everything you want!

And this is how you repay me?

Huh? Answer me!

Getting such a score?

What a disgrace!

Okay, that's enough.

She'll do better next time.

Calm down now.

Next time?

Study?

Forget about that!

And you!

You spoiled her to this!

Let me tell you,

you don't deserve to be my daughter!

Mom!

What now?

Will Dad kick me out?

He won't.

Don't worry.

I'm here.

I'll protect you.

It's fine.

But won't others

find out about this?

It's okay.

As soon as you agree,

I'll arrange surgery

for your mother immediately.

I'll perform the surgery myself

and cover all the expenses.

Good kid.

That time,

I wanted to send Youmei

to study abroad.

So I asked Yuan to take the TOEFL for Youmei.

The first year,

Yuan took the test for Youmei.

And the next year, she took it herself.

Unexpectedly, she didn't

perform well the following year.

It was my fault.

So Liu Yuanyuan felt

you ruined her life

and kept threatening you for these eleven years.

And then you killed her

out of anger?

It wasn't like that.

Yuan was a good kid.

She never blamed me.

She just felt

very guilty about it.

She thought

she messed it up

because she was nervous.

So I also wanted to sponsor her

so she could go back to college.

But her mother's illness

was dragging her down.

It was a bottomless pit.

A few days ago,

Yuan came again.

She said her mom's illness was back,

hoping I could help her again.

Her mother's illness kept recurring.

I knew she had been suffering.

I felt bad about Yuan

being dragged down

by her mother.

I wanted to help her badly.

But I knew

the only way to fix this

was to solve the root of it all.

That's why I went to her mother.

Huizhen,

it's been years.

Yeah, Dr. Gao.

I don't have much at home.

Please don't mind.

Yuan mentioned

you haven't been feeling well lately.

So I came to visit you.

Thank you.

You also know

my condition.

It's beyond treatment.

If it hadn't been for Yuan,

I'd have given up long ago.

Yuan is a good girl.

Don't you feel bad

about dragging her down for years

with your illness?

Do you know that

Yuan could have gotten into medical school

and had a better life than this?

You're the reason why Yuan

ended up like this today.

She... She...

Why exactly did you do that?

I just wanted her to realize

that she should give it up.

Give up on herself

and set her daughter free.

Yuan's life

was ruined because of you.

You said you were holding on for her.

But have you ever asked

whether she wanted this kind of life?

I know your condition well.

Let me be frank with you.

Keep stalling like this,

and you're only a burden to her.

No...

Yuan wouldn't think this way.

She wouldn't.

Of course Yuan won't.

She's a good child.

But you?

If you were really

a good mother,

you should

just give up on yourself

and stop torturing her.

To be honest,

you'll eventually die someday.

But she?

She'll still have to pay off

the debts owed because of you.

You want to stay alive?

You only want her life

to be ruined just like you are!

So you killed Liu Yuanyuan's mother

for her own sake?

I've seen too many patients

like her mother.

Her illness kept recurring.

When would it even end?

If she wanted her daughter

to have a good life,

that was the only way.

Besides,

we will all die in the end, right?

I only taught her

how to be a good mother.

You're so selfish.

You said you wanted to help Yuan.

But why did you kill her?

Don't you think this

is contradictory?

That day, Yuan came to my lab

and gave me a button

her mom had ripped off

from my clothes.

Yuan,

listen to me.

It's alright.

Though your mom's gone,

you can start

a new life now.

I'll help you.

Don't worry.

It was you who killed my mom!

It was you!

Yuan!

Yuan!

No...

Yuan, don't be stupid!

Yuan!

Don't...

Yuan!

Stop...

Stop it!

Yuan!

Mom!

No...

Mom...

Mom...

She...

Mei,

listen to me.

Put her clothes on you.

I'll handle the rest of it.

I've got it.

Don't be afraid.

I'm here with you.

Just do as I say.

I only did all of this

to help my daughter.

And she had

nothing to do with this.

I hope you can

let my daughter out

and tell her

to live happily.

Xi.

What is it?

One's missing.

My mom...

How is she now?

She has confessed.

She admitted she killed Liu Yuanyuan.

You mean

my mom confessed?

She wouldn't...

Please tell me

what will happen to her.

According to legal procedures,

the prosecutor may charge your mother

with murder.

Then?

The court will make a judgment.

It's my fault...

It's all my fault...

If my mom hadn't wanted

to protect me,

she wouldn't have

asked Liu Yuanyuan to take the exam for me.

It's my fault... My fault...

It was me...

All my fault...

And what will happen to me?

You're suspected of harboring.

The court will sentence you according

to the severity.

Your mother wants you

to live a good life in the future.

Ding Youmei is

not what we thought she was.

My mom said everything she did was for my own good.

But was turning me into the good girl she expected

really good for me?

Mei made a big mistake.

I'm begging you.

Do you realize that your actions

are hurting her?

Do you study the brain's reflection of light

to help Li Ming develop drugs?

How did you get this information?

I solved the Raw Diamond Case.

I know him better than you do.

Zhai, your daughter fell off!

Truth comes after evidence.

But you've got it backwards.

Zhai Xixi didn't fall by accident.

Why did you kill her?

Why did you kill her?

It's murder.
