Medical Examiner Dr. Qin (法医秦明)

The victim is young.

Her hymen is intact.

Rule out non-standard sexual intercourse.

No sexual assault?

She was strangled and died from mechanical asphyxiation.

The greatest mystery lies in her hand.

It was stomped hard by a shoe.

Why would she wrap up an empty ring box so carefully?

This ring must mean a lot to her.

We can be sure of one thing.

Qi Jing Jing has a mysterious boyfriend.

Why is the victim missing a molar?

What's wrong?

Was the air conditioning on?

How did you know?

Air conditioning doesn't smell the same as heat.

You're right.

When the police arrived the air conditioning was on.

This isn't really the season for air conditioning.

Your nose is so sharp.

By the way, we found a ring box that is the same style as Qi Jing Jing's.

Your speculations should be correct.

Sun Kai was Qi Jing Jing's mysterious boyfriend.

From what we found out

they lived together for quite some time.

Then they broke up for some unknown reason.

However, about a month ago

they started to be in contact more frequently.

Are there any useful fingerprints?

Qi Jing Jing's fingerprints were found on quite a few objects.

Let's see what the corpse can tell us.

Sure, this way.

The corpse is still fresh. Could the murderer have just left?

No.

His time of death should be earlier than Qi Jing Jing's.

But there's no sign of decomposition.

Do you not see this huge area of livor mortis?

You were blocking it.

How did you figure out his time of death?

It's very simple.

The victim was soaked in the tub to mislead us.

He was soaked in cold water postmortem instead of hot water.

If he had been soaked in hot water

the submerged skin would have turned a pale pink

and the exposed skin would be pale.

But we don't see that here.

The murderer soaked him in cold water and turned on the air conditioning.

That's why the corpse doesn't smell very much.

It also makes it difficult for us to determine the time of death.

How did you determine that he was killed before Qi Jing Jing?

Qi Jing Jing died no more than 32 hours ago.

As for him, it would take at least 36 hours in such an environment

to develop such severe livor mortis.

The cause of death is probably strangulation.

The murder weapon was a rope.

But the pattern seems a bit weird...

It's a similar MO.

We can reasonably suspect that

both murders were committed by the same unsub.

What is he doing?

Send the corpse back to the autopsy room right away.

We have to examine the body quickly.

Yes.

I'll be there right away.

You got kicked out again?

What's the point in getting changed?

It's none of your business.

Fine... fine.

By the way, I have new clues.

Would you like to join me?

I would.

I won't take you.

Jerk!

The guy died first.

Followed by the woman.

They were both strangled to death.

This could be the murderer's usual method.

So, after the unsub killed you

he filled your bath tub with water and dumped you in it

to make it look as if you were attacked while taking a bath.

If you really had died while taking a bath...

It's been two days already.

Skin soaked in hot water would have turned a pale brownish pink

while the skin outside the tub would be sickly pale.

There's no such difference in your skin tone.

Judging from the strangulation marks

you were strangled and you died from asphyxiation.

But the murder weapon isn't a rope because there aren't any friction marks.

There isn't any fiber.

It could be...

It could be that stereo cable.

You seem like a man who could throw a few punches but you didn't fight back.

You were caught off-guard.

You were defenseless.

You looked down on the murderer.

He's neither tall nor strong.

If you were to take him on he would have been no match for you.

But he still took a great risk to kill you.

In terms of men's dignity, not including money...

It would have to be...

You have a tattoo at the back of your waist.

I got it.

If I got it right...

You should also have a tattoo on the same spot behind your waist.

But you had it removed.

All I can say is that you once loved Sun Kai.

You were once deeply in love but you had to give up.

You just had your hymen reconstructed.

It was about a month ago.

That's about the same time you had the tattoo removed.

What disappointed you so much?

Your finger shows that you were still wearing the ring.

But he wasn't.

Perhaps it was just wishful thinking on your part.

Perhaps you wanted to marry him

but he was just toying with you.

Yet you still kept the ring.

There's a fingerprint on your face.

It's stained by lipstick.

Does it belong to the murderer?

The murderer tortured you.

But he caressed your face one last time after you died.

He stained his finger with your lipstick and left a print on your cheek.

But he didn't rape you.

Does he find himself unworthy to make love to you or...

Perhaps he doesn't know much about sex?

Chief Qin.

We went to visit Sun Kai's parents to gather some information.

They told us that Sun Kai and Qi Jing Jing were lovers.

But they despised Qi's upbringing.

They find her unworthy of their son.

Therefore, they didn't approve of their relationship.

It wasn't until six months ago that Sun Kai told them

he wished to marry Qi Jing Jing.

Sun's parents were furious and threatened him with their lives.

Sun Kai had no choice but to break up with Qi Jing Jing.

Does equal social rank between families really matter that much to you?

You took my virginity! What else do you want?

What am I supposed to do now?

After Qi Jing Jing broke up with Sun Kai

she went on dating websites

to make up for her psychological imbalance.

But a month ago, Sun Kai wanted to make up with Qi Jing Jing.

His parents still disagreed so he moved away out of rage.

We found out through a social networking site

that Qi Jing Jing had been in contact with many people on the dating websites.

She also took part in a few meetup events.

Take a look.

In the past six months

she posted lonely-hearts ads often.

The timeframe matches her break up with with Sun Kai.

She even emphasized that she was a virgin.

Exactly. Isn't that too weird?

Who would still care about that nowadays?

Would that hymen guarantee a lifetime of love?

It's not some preservative.

Ironically, when I re-examined her

I discovered that she had her hymen reconstructed.

A reconstructed hymen?

She also emphasized that she's a virgin...

It might have to do with the guys she interacted with on the dating site?

Go through all her messages on the dating site.

How many people contacted her?

Roughly speaking...

About 100 men.

So many men?

How long will it take us to go through all of them?

Damn it. What are you doing here?

I'd like to talk to you about virgins.

About virgins?

Strictly speaking, it's about the unsub, the hymen, and the victim.

Come in, we can talk about the case.

I came here late at night to hear your opinion on this matter.

You've never been interested in the motive before.

But this time, there are some things I just can't figure out.

I need your opinion.

Why would a woman reconstruct her hymen?

It's simple.

There's only one reason.

She's not a virgin.

So?

All choices draw on the advantages and not the disadvantages.

What advantage was there for Qi Jing Jing?

I can't answer that right away.

But I think what matters more for our case

is to go through those blind dates she had.

Which of those men listed such a requirement?

That's why I came to see you.

As the only woman close to me who has had a blind date

has anyone ever made such a request to you?

I think that you should ask yourself this question first.

For a freak like you, would you ask that of your girlfriend?

- What does this have to do with me? - What does this have to do with me?

Captain Lin, they are all up here.

Good.

We have already filtered out the blind dates that meet your requirements.

These are men who contacted Qi Jing Jing

around 1.7 meters tall, wealthy, and required her to be a virgin.

There are 23 of them.

Although we have narrowed them down a lot
