Bro, you are a policeman, not a thug.

Why do I need to explain to others how I behave in my life?

But facing his father, he didn't dare to show off!

"Dad, if I tell you, I saw it accidentally."

Xiao Mu rolled his eyes, "Do you believe it or not?"

"hehe!"

Xiao Guodong sneered and tilted his head to look at his son.

Do you really think that this old detective like him is fake?

My son saw the Bingcheng case in Beijing. What's going on?

"Then what if I say..."

Xiao Mu knew he couldn't hide it anymore, "We are at the same level now, what do you think?"

Same level?

Minor subject?

What a joke!

Xiao Guodong was stunned for a moment and laughed angrily.

He had been a police officer for almost twenty years before becoming a deputy officer.

I thought my son was talking nonsense.

It's not that he doesn't trust his son, it's just too fantasy.

How long has Xiao Mucai been going to school in the capital? Two months, right?

A policeman who is nothing and has just become a full-time police officer.

An 18-year-old boy who is not a party member, did you tell me about the minor department?

The 18-year-old deputy subject, Longguo, has anyone heard of it in recent years?

How can he, a father, write this letter?

Xiao Mu said nothing and took out a police card from his pocket.

This is a new certificate for transferring a public security officer to the Special Case Investigation Division of the Ministry of Public Security.

Xiao Guodong was slightly stunned when he saw his son's ID.

My heart couldn't help but beat wildly.

Could it be...

He took it and opened it.

I glanced at it and was confused.

…

Name: Xiao Mu

gender:……

blood type:……

Date of birth:…

Position: Special Case Investigation Division, Ministry of Public Security, deputy section level

Warning number:…

Police rank: Superintendent First Class

Validity period:…

Supervised by the Ministry of Public Security of Longguo

…

Xiao Guodong was stunned for half a minute.

My scalp started to feel numb every inch, and my heart was beating uncontrollably.

I can’t tell whether it’s happiness, excitement, relief, or fear...

Why panic?

They are all police officers. Is there really an 18-year-old deputy officer who doesn’t understand what the First Class Superintendent represents?

Some ‘rules’ were broken!

Break with what?

The great achievements are at least those earned in a narrow escape.

Moreover, it was not just once, but many times!

After a long time, Xiao Guodong raised his head and looked at his son, "How many police officers are there now?"

Xiao Mu told the truth, "Remember, six personal first-class police merits."

He only dared to talk about police merits, not military merits.

Not to mention first-class military merit, even second-class military merit is scary.

Sure enough.

"hiss!"

Xiao Guodong took a breath of cold air, and the tone of his voice changed, "Six, six times first-class merit?"

"Um."

Xiao Mu nodded, "It's all on my resume. You can see it if you check it."

This is a 'normal' personal profile, accessible to certain groups of people.

But he also has a different file that only a few people can see.

Ordinary police officers are not qualified to access this kind of 'special secret' file.

Father and son looked at each other silently.

"Don't tell your mother."

"That's what I thought too."

"Ha ha……"

Father and son both laughed at the same time.

Xiao Guodong patted his son on the shoulder, feeling pleased and proud at the same time, "Dad will be proud of you from now on!"

This is my fault, how can I not be happy?

"Yan, it's serious."

Xiao Mu didn't know whether to laugh or cry, "It's because you teach your son well."

"Ha ha ha ha……"

After some ‘commercial bragging’, both father and son were laughing.

They didn't mention the credit again because they all understood.

From the moment you choose this career and put on your police uniform.

They have all become aware and have even made some preparations.

Now.

As long as you are healthy and alive, that's enough!

"What did you find?"

Xiao Guodong took the cigarette from his son, lit it and took a puff.

"It's very abnormal. I can't see anything wrong at the moment. I have to go to the scene to take a look."

Xiao Mu frowned, "If it's what I think, the Heilongjiang Public Security System may be in big trouble."

What did he think of?

Serial murder.

If this happens, it’s enough to give the Heilongjiang Province’s public security system a drink!

"Let's have a bite first." Xiao Guodong walked towards the team.

Xiao Mu followed his father and had a quick bite in the second brigade.

Then the father and son had a 'chat' with the captain.

When Liu Qiang saw Xiao Mu's ID, he became numb.

I still remember that Xiao Mu came to him to learn how to investigate crimes, and he was not even a police academy student.

In the blink of an eye, he became a ‘leader’.

Don't look at Xiao Mu's lower level than him.

As long as the identity of the Special Case Investigation Division is revealed, provincial and municipal leaders will have to greet them personally.

This is no joke!

…

The crime scene was in the residential building involved.

7th floor (loft).

No one was home, police were guarding the house.

The old couple committed suicide because of their daughter and are now living with relatives.

The eye of insight... Xiao Mu stood in the loft living room, observing the ground.

The footprints were unusual, but not coercive.

The traces of 'moving' from the footprints on the ground are consistent with the 'zombie steps' of the deceased on the surveillance.

Through the process of moving the footprints, it can be analyzed that the deceased's mood at that time was...stable.

Can this be seen?

able.

Just like when a person is in a happy mood, his steps are brisk and his pace becomes faster.

If a person's mood is dull and his steps are heavy, his pace will be slow.

When you are angry, excited, or excited, your steps will be large.

When you are afraid, frightened, or sad, your steps will be small.

But it is not absolute, you can only analyze roughly.

There are criminal investigation formulas for these, and teachers will teach you when you are in police school.

While investigating, Xiao Mu matched the whole process of the surveillance video in his mind.

It matches, the deceased's "autonomous" behavior!

At the balcony.

Xiao Mu investigated all the traces before the deceased jumped off the building and found no abnormalities.

It was the second and third investigations, but nothing was found.

Then, he walked down.

Came to the place where the deceased fell from the building.

Took the tablet computer handed over by my father and watched the investigators take evidence photos at the scene at that time.

Comparing the photos, he investigated the ground a few more times.

Xiao Mu suddenly frowned, "It's a bit coincidental!"

The process of the deceased jumping off the building to commit suicide was to fall from the building in a "falling down" posture.

The floor height calculated from the balcony is 23 meters.

Calculated according to the law of free fall motion.

About 2.5 seconds.

The deceased jumped from the building in a forward-leaning posture, and her head and neck happened to touch the ground when she landed.

This is the biggest cause of death.

Suddenly, Xiao Mu's eyelids jumped.

No!

Although the deceased's suicide by jumping from the building is very... standard.

But there is a problem.

Why did the deceased jump out of the building in this way?

Why did she just land on her head and neck in this way?

The 7th floor is not high, but not low.

However, the mortality rate of jumping from a building at this height is not very high.

People who don't understand think that jumping from a building will kill you, which is nonsense.

23 meters high.

If the legs and torso land first, the mortality rate is only about 10-30%.

The biggest cause of death is the impact of the head and neck, cervical vertebrae and skull injuries.

"Why did she choose to jump out of the building instead of... jumping?"

Xiao Mu murmured, "Why is it such a coincidence that the head and neck landed first?"

Could it be... that the deceased calculated it?

Or, someone calculated it?

If the assumption is true, Xiao Mu's face sank.

This is a bit scary!
