Three bloody fingerprints. Write it down.
-So? -Captain Guan.
Three bloody fingerprints on the seat fabric.
The killer probably wouldn't leave his own behind.
We also found stains from glue residue.
Glue residue?
Sure enough, his fingers were treated to cover up his prints.
Guan Hongfeng left the force but is now back,
pretending to assist us
without remuneration.
He's merely protecting someone.
To him,
his brother
is more important than upholding justice.
He's even more important than that family's lives.
What value do you think Guan Hongfeng has?
Put those here.
Thank you.
How's glass fragment collection going?
They are still sorting them out.
Get back to me ASAP. I want to know what broke it.
Yes, sir.
What's wrong?
Mr. Guan.
Today, Vice Captain Liu took me to...
I still want to ask you.
There is so much conclusive evidence that points to your bother.
Why do you still strongly believe that he is innocent?
Don't you think it's a violation of your principles as a policeman?
Or perhaps
you've seen Guan Hongyu
since the incident.
Right?
My brother and I grew up together.
Nobody knows him better than I do.
He does make mistakes.
But he's no murderer.
Because I trust him.
Please.
When did you get promoted over me?
What do you mean?
We have such a big murder case.
Yet you gave your girl a tour of Shuguang building 4.
Even tried to get closer to the mayor.
Why can't you just do your duty as a policeman?
No problem.
You, Zhou Xun, are the captain.
Please assign the task, Captain Zhou.
Fine.
In the interrogation rooms,
the victims' families do not agree with the autopsy report.
Since you are so good with people,
they are all yours.
Mr. Guan's asking.
Any update on this?
Nothing.
This type of glass breaks
into fragments, with round edges, shaped like honeycomb cells.
Many of them
are similar in shape, measuring 0.3 cm, like this.
I'd like to see how Captain Guan can piece this crap back together.
Captain Guan wants us to restore it
so he can figure out what broke the window.
Since the shapes are similar,
we just need to find the inconsistent ones
with signs of damage.
Put those together to find the point of impact.
Right?
-That's right. -Come on.
You're not open yet?
Your birthday?
Uncle Geng's.
So that's why the long face.
Let it go.
I know.
I owed him a lot.
Those people who give may not think so.
You know...
when I was young, my family was very poor.
Dad died young.
Mom brought us up all by herself.
Then she became ill.
To make more money,
my brother did a lot of illegal things.
And was expelled.
I even sent him to jail.
Honestly...
I know I owe him.
But I don't know how to tell him.
Now, thinking back,
perhaps there's a lack of...
mutual understanding between brothers.
I do feel that it's not easy for you two.
Guan Hongyu.
Stop complaining.
I saw you guys changing in the warehouse.
Don't worry, I won't tell.
I believe you.
Unbelievable.
You Peeping Tom.
Captain Guan.
IT'S GETTING DARK. I'M AFRAID WE NEED TO PUSH IT UP.
MEET IN HALF AN HOUR. FIND THE NEAREST SAFE PLACE.
CHANG FENG CRIMINAL POLICE
MUSIC BAR
-He's here. -Hi.
Can you talk about Li's case?
Any new progress?
Was Chang Aiai raped?
Are you Captain Guan Hongfeng, who left?
Were you reinstated?
And your brother's case?
They said Li was naked.
If he raped Chang, will it be a case within a case?
That's right. Please answer.
Vice Captain Liu will hold a press conference for all questions.
Vice Captain Liu, didn't Captain Guan leave the force?
Was he reinstated?
-One at a time. -What is it?
MUSIC BAR
Bro. We should've done this a long time ago.
Zhou Xun kept coming to our place. We would've gotten caught.
We can't help it today.
Home is the safest.
If we keep coming here,
they'll find out.
Actually, we were seen last time.
Last time?
Yes.
If I don't believe you,
I would've called the cops.
I'm not kidding.
But you two look so much alike.
Come on, alike?
The same in every way.
In every way?
Every way...
What does she mean?
Nothing. Why don't you just crash here tonight?
What the... Sir.
The Li-Chang murder case has over 100,000 views.
Who?
LI AND CHANG MURDER CASE
Liu Changyong.
Look at what you've done.
Dong Han has already sent the photos.
We could've gotten the photos back.
Now they are all out there.
You can't stop the news even if you detained all the reporters.
Liu Changyong...
It's your fault if we can't crack this case!
You even involved the whole team!
Why are you so mad?
She got us the district files...
and has left already.
What's with the blowup?
Take your crap somewhere else.
How dare you?
Sir, look at this.
Besides complications of the case,
we've found that one of the investigating officers is former captain Guan Hongfeng,
who left the force previously.
Half a year ago,
Guan Hongfeng was implicated due to his twin,
Guan Hongyu, being the main suspect in the February 13 murder case.
As for when he was reinstated into this position,
the Changfeng District team has yet to respond.
-Did you do this on purpose? -What do you mean?
-Calm down. -Captain Zhou.
Where's Guan?
I'm asking about Guan Hongfeng!
Hey.
Listen to yourself.
Everyone can hear you.
Everyone's been busy. Let's be understanding.
Enough understanding. Come, look. Look at this.
It's already done. There's no point yelling.
We can solve the case to quiet this media circus.
Have a seat and let's discuss.
Where were you?
I was at Liu's press conference.
And I called road traffic control to retrieve
the before and after CCTV footage around the scene.
Come on, hurry.
It was confirmed
during the autopsies that both victims' time of death is around 1:20 a.m.
The technical team will confirm victims' ID.
Why all this trouble?
Can't we just keep the line?
No way.
What if somebody calls you
and your line is busy?
I have no idea what to say if they want me to speak at the meeting.
You need to back me up.
Just follow my lead.
Be gentle.
Obvious stab wound on the left of his occipital bone.
The murder weapon is a pyramid-shaped object with a 60-degree-angle tip.
A stab to the head pierced the cerebellum and occipital lobe.
It caused severe internal bleeding.
While a date-rape drug was in the car,
traces weren't in the female's blood.
Seems like these findings match her opinions at the scene.
Let the technical team continue.
What about you guys?
Because of the weather, no footprints were found.
Except for the victim's vehicle, there was no signs
of other vehicles at the scene.
Therefore, we believe
the killer walked to the scene.
All three bloody fingerprints on the seat fabric
belong to the female.
The male victim is confirmed to be Li Dishen,
23 years old.
Entrepreneur Li Shanyi's only son.
He was previously detained due to a fight.
He got lots of media attention
for his scandalous relationships with various celebrities.
The female victim, Chang Mengran,
was a popular internet celebrity, Chang Aiai.
Nineteen years old, no priors or criminal record.
Chang Mengran's ID photo.
Of course, the most important evidence from the scene
was the phone intended as a hidden camera found between the front seat cushions.
This recording...
it's too dark to see anything.
This is only part of the video.
Li Dishen did turn on the headlights for recording purposes.
But Chang Aiai requested to turn it off.
You can tell from the video that
the murder happened when both victims were having sex.
The front seats were pushed forward.
But after the murders,
the seats were restored.
When the seats were moved,
the phone fell between the seats.
Judging from the voice in the background,
the killer cleaned up in the car for 12 minutes.
He did not make a sound the entire time.
Until the police arrived, no videos were recorded.
Ask them what broke the rear window.
The window?
Per your request,
we put together a portion of the glass pieces.
Based on the damage, preliminary findings show
that the rear window was hit
by a cone-shaped, 0.25 cm long on each side,
sharp weapon.
Match the murder weapon.
Equilateral triangle, cone shape, 60-degree angle.
Is that what broke the window?
It's similar to the shape of the murder weapon.
Was any hair, fabric, chipped paint...
Or other DNA evidence found at the scene?
No.
The vehicle was cleaned thoroughly.
Did he leave any...
Detergent residue behind?
No.
But we collected five soil samples.
This may not matter much, but I still have to ask.
What did the victims have on them?
Jewelry, accessories, et cetera.
Nothing was lost.
And... Chang Aiai...
The sexual activity was consensual.
Of course, you can hear that from the video.
No signs of sexual assault after she was killed.
He wasn't after wealth or sex.
What do you think?
We do not have enough evidence.
Because of the time and weather,
the chances of finding any witnesses and other evidence are small.
We'll need to conduct more interviews and gather more evidence.
Expand the parameters. Also, I have requested the footage.
Technical team should follow up.
We can't see the killer's features clearly on video.
Especially the shape of the weapon.
Can you enhance the video further?
I'm afraid we can't. But if we pass on the video to
HQ or the Institute of Forensic Science, it could be enhanced further.
It'll be the same at headquarters.
Try the Institute of Forensic Science.
Leave it to me. I know them.
I'll have them give us the results soon.
INVESTIGATION UNIT
I don't need to say it again.
We all know the urgency of this case.
Get back to work.
Dismissed.
CHANGFENG CRIMINAL INVESTIGATION
-Make Zhou Xun stay. -Hold on, Zhou Xun.
-What's up? -Too much information has been leaked.
Keep this conversation between us.
In fact, the most obvious lead from the scene is that
the killer showed signs of mild OCD.
If cleaning up the crime scene was to avoid being caught,
then tidying the victims' clothes, adjusting cushions,
and restoring the seats are behaviors
that show a person's character traits.
Also known as a criminal's MO behavior.
The killer skillfully got rid of all identifying evidence at the crime scene.
I have a feeling this is not his first time.
If I remember correctly, none of the recent cases in our district
are similar.
I will request more resources from the bureau
for any unsolved cases with similarities within the past five years.
Sir, in the office...
Can't you wait?
Chief Gu is here.
Chief Gu.
-How can you let this happen? -You don't want to know.
Rights are greater than laws here.
-Even the victims' photos-- -Not that.
The HR department of the bureau called me directly,
asking why Guan Hongfeng is still working in our unit?
Wasn't this approved?
To solve the case, anything is possible with a closed door.
But this has leaked and is now public.
It created a social uproar.
The bureau has given the order.
Within one week,
I am to report back with
your head and the details
of this mess.
But, Chief Gu,
we've seen Guan's results since his return.
You still don't get it, do you?
This is not about Guan Hongfeng.
If we can't give the bureau an answer,
it's over for both of us.
The bureau has no idea about you being our consultant
and wants the case solved in a week.
Otherwise, you won't be the only one leaving.
So time is of the essence now.
If we can't find any similar cases
in our search within the bureau...
Then we'll request a nationwide investigation.
This is not his first time.
He must've killed before.
Our signature pasta.
Stop looking at me like a criminal.
Your total is 48.50.
Can you narrow down the area a bit?
Hey.
You slept with Liu Yin?
I said, can you narrow down the area?
Weather, target, and behavior characteristics.
Which are...
a storm, late at night,
and a couple's secret meeting.
These make up an almost-ideal environment for crime.
The couple wanted to avoid attention.
No one's out late at night,
and the storm reduced the chance of having a witness.
So I don't think the storm is a coincidence.
It's likely he chose that day.
Once confirmed that this is a serial killer case
within the city,
a special task force will be set up
with the best people
coming from all the other districts
involved in the murders.
If they can't solve the case?
We'll get it from the Ministry of Public Security.
What if it's solved?
It's supposed to be solved.
I mean, if we solve the case within the time they give you?
Let's say...
within a week.
Or shorter.
Judging from the type of case,
it'll be a great commendation.
And if we solve the case
as a result of me returning to the investigation team?
Then it shows that the station's choice
to bring you back was right.
Good. I'll leave it to you to go through the archive with the team.
I am heading home.
Here it is. Look at this.
-What do you think? -Why don't you mark two more down.
8802.
HOMICIDE CASE A2
Man...
Come on. Help.
Haigang District, Liu
Hello.
Captain Zhou, I found one.
Last year. Field south of the Liangma River.
Storm. A male and a female.
The rear window was broken. No evidence found.
Captain Zhou.
They found two more cases in Haigang District.
Guan.
How was it?
Besides last night's incident,
four similar cases
occurred in the city within the past five years.
That's one per year.
Oh, and...
they approved to set up a special task force two hours ago.
Due to the shortages in Xiangyang,
people from Haigang will assist us with the case.
Captain Zhou.
They are here.
All right.
Everybody up. We've got work to do.
Oh my goodness. Hey!
Zhou.
I can never get away from you.
I am now the team's captain,
and you're still a vice.
What have you been doing?
It's only because you got a good teacher.
-Haigang, Vice Captain Zhao Xincheng. -Haigang, Zhao Xincheng.
You must be Captain Guan?
-Heard a lot about you. -He's from the same year
as Captain Zhou and the only one at his level.
I'm just a consultant now.
Zhou Xun told me
your status won't change even if you're not on the payroll.
I have a consultant as well.
Han Bin.
The son of Professor Han in our unit.
We recruited him as he is a lawyer.
Hello. I've read your book Dichotomy of Crime. It's a good read.
Hope to learn from you and your father.
Thank you.
My dad is busy, so I'm here just to fill in.
Okay, let's go over the case.
-Come. -Let's go.
Who is he?
I don't know.
But Han Songge is a well-known criminal profiling expert.
Based on the timeline, incidents in Haigang are the first.
From the criteria you shared,
there are indeed two cases with a similar MO
within the past two years.
The first was outside Linye University.
It was a stormy night.
Victims are a 53-year-old male, Li, and a prostitute, Liu.
They were having sex in Li's vehicle.
The rear window was broken.
Causes of death were stabs through the head with the same murder weapon.
No other evidence was found.
The vehicle was cleaned spotless,
even the fire extinguisher.
We have no fingerprints or other viable evidence in this case as well.
The victims' bodies had been moved,
and their clothes were tidied.
What's amazing was the male victim's
zipper and belt were redone neatly.
But he still had the condom on.
As for the year before,
the MO is similar.
The only difference was
they were in the front seat.
The female victim was giving the male victim a...
In short,
although it was the front seat,
the killer gained entry to the car
through the window.
It was a stormy night as well.
No witnesses.
Everything is in the file. Take a look.
This happened last night, in our district.
Last year, in Xiangyang, near the Liangma River.
A male and a female. Car windows broken.
The time was around 2:00 a.m.
The scene was cleaned thoroughly.
The victims' bodies and belongings were reorganized.
These cases are similar.
Zhou, do you think there are benefits to investigating these as one?
In my opinion,
this is a serial murderer case.
Since it was a serial case,
through the similarities and differences of each incident,
we will have new leads to aid our investigation.
But...
this killer is different from the other serial killers.
His cooling-off period lasts up to a year.
This is rare.
It's always the rear window?
Yes, even the one with the victims in the front seat.
The killer broke the rear window.
Just like the weather, it was the killer's preference.
Maybe it's because
the vehicle manufacturers tinted the rear windows already.
Car owners don't often add another layer.
So the killer felt that the rear window was the easiest.
It's possible.
The killer probably
knew what he was doing from the start and knew how not to get caught.
His MO is consistent in every case.
A few differences in the first two.
In last night's incident,
presumably, the killer took 12 minutes to deal with the bodies and the cleanup.
But it was longer
in his first kill.
CHANG FENG POLICE
Bodies' stiffness?
Correct.
In other words,
he took at least one hour after the victims died.
Seems like he wasn't too skilled in his first kill.
Dear masters,
let's hold off on the discussion
and look for valuable leads.
Based on the video, the killer is a male.
About 1.8 meters tall.
From the way he handled the aftermath,
he might have minor obsessive-compulsive disorder.
Although he walked to the car,
with the timeline and the geographical area in mind,
he should have a vehicle of his own.
He's 40 or older,
is or was in the criminal investigation field.
Roaming around at this hour,
he's either living alone or with his parents.
Long time off...
It's possible that he has a normal family life.
When the cooling off is too long,
it makes his urge to kill harder to control.
Which will change the frequency of his kills.
There are eight million people living in this area of Jingang.
Can we narrow it down?
Captain Zhou.
We got a vehicle
on surveillance footage.
Let's have a look.
Let's go.
Captain Zhou, where can I see the bodies?
-The coroner's... Let me take you. -Okay.
The wound is nine cm deep.
Same length as the weapon.
Is it more accurate to say the weapon is at least nine cm long?
I haven't read the other files.
But the two in Haigang,
the wounds were less than nine centimeters.
Imagine...
The killer must have used all his strength to stab through the skull.
Upon penetrating the skull...
the force will naturally drive it
all the way through.
He might not have utilized physical strength.
The murder weapon isn't visible.
Looking at the arm holding the weapon, no strength was being applied.
Did he push the victims' heads against something?
In a sense.
Should be something that can be handled with one hand
and used more than once.
An electric pressure device.
And the tip angle of the weapon?
We can't tell.
But we've restored part of the broken window.
From the video,
the killer didn't have time
to switch weapons.
If the window was
broken by the murder weapon,
it should be cone-shaped, used at a 60-degree angle.
Sixty-degree angle.
It fits the window breaker.
I think so, too.
He might have modified it into an electric pressure-controlled dagger.
Unfortunately, this doesn't help with the case.
Thanks, Dr. Gao.
Captain Guan.
One more thing.
This is Li Dishen's autopsy report.
Just give it to Zhou Xun.
A big case like this,
it's better to put it to good use.
IDENTIFICATION STATEMENT
CASE NAME: 213 HOMICIDE
12:47.
Northeast side.
Take note of the license plate. Look for the owner.
That's all.
From midnight to 2:00 a.m.,
17 vehicles were seen around the crime scene.
Any of them appear more to you?
Hard to say.
Check all of them.
Give me the registration information.
I'll head over with my team.
Can we see when the victim's car entered the area?
Not yet.
It's possible it got there before midnight.
It's also possible
the killer followed them from Huogong Club.
What do you mean?
Assuming he chose a random target,
he likely did it at a crowded location.
He locked down his target.
Instead of roaming around hunting.
Since he is cautious enough to clean the scene,
even if he drove,
he wouldn't be so careless
and drive to an area with CCTVs.
Then we should expand the parameters.
Retrieve the surveillance videos around Huogong Club.
Whatever it is, look for the victims' car.
If the killer followed the victims,
we should be able to find him
based on the victims' route.
Hello.
All right.
The Institute of Forensic Science.
I'll head over.
I'll go with you.
Liu, there are reporters out there. Take the basement.
Let's go together.
