After receiving the flashlight that Liu Qingshan handed over, Chen Yan lay on the ground and shown it inside.

At the same time, some pungent blood comes, and the familiar smell on Li Yansong.

Finally found it!

Ten minutes later, everything in the squatting toilet was taken out.

A gray -blue labor insurance, light gray jeans, and a pair of white sneakers.

In addition, Chen Yan and Liu Qingshan also found a box of adhesive tubes with a few meters long circle.

In addition to these, there is also a notebook.

Liu Qingshan picked up the white sneakers for the first time, looked at the following lines, and was exactly the same as the prints from the scene extracted on the scene: "This pair of shoes!"

Because each pair of shoes is different, even if they are the same person, the shoe prints left in different periods are unique.

Therefore, in principle, as long as there is this pair of shoes, Wu Degui's evidence of killing Li Yansong, even if it is true.

**************************

When Liu Qingshan tidy the clothes worn by Wu Daigui's killing, Chen Yan took the black leather notebook.

On the black outer skin is the "notebook" font

The corners have been yellowed, and the black sheet has more wear.

This style of notebook should be a product of more than ten or twenty years ago in Chen Yan's memory.

But from the degree of corner rolls and the ground -worn parts, its owner obviously reads often.

Open the notebook, the first title page is a very beautiful hard pen font.

Prize: Wu Degui won the title of the difficulty of truck transportation, rewarding notebooks to encourage capital.

Instant unit, Shenshi first transportation company, 2001 time.

This is……

Twenty years ago, things.

The background information about Wu Degui is being investigated, but there is no valuable clue.

At present, I only know that Wu Digui's household registration is located in Shen's city, but he did not find a real estate in his name.

I did not find the information of his marriage, and the information of the hukou registration was relatively simple.

The people in this courtyard are not familiar with Wu Digui, and they don't know what he used to do.

Shenshi First Transportation Company ...

It turned out that Wu Degui worked at the first transport company in Shenshi.

The first transportation company has been established for a long time. It has a history of about seventy or eighty years, but twenty years ago, due to changes in the economic development model, it closed down.

The company was restructured into Shenshi Bus Transport Group Corporation.

"Master, wait for the Shenshi bus transportation collective company to check the archives of the Shenshi first transportation company that year. Wu Degui once worked in this company."

"See what you can find."

"good!"

Liu Qingshan agreed, and immediately arranged for related work.

Chen Yan continued to look at the diary.

The first page.

Monday, the weather is light rain.

"Lao Li last month for 5 cents, say good today, but give me today, but didn't give it."

"How could I lend him money at the time? Lao Li was a well -known deduction. I guess I couldn't get it back for 5 cents."

"It's really not possible, tell him, but everyone is a colleague, because it is not good to turn the face with a 5 yuan for 5 cents."

"Forget it, the money is not needed, let's get the tire of his bicycle."

On Wednesday, the weather is fine.

"I saw Qin Yu's meals at the door of the cafeteria today."

"Qin Yu looks so beautiful, but unfortunately followed Zhang Huaiying's fart."

"Didn't you just shoot the leader? Be the director, otherwise the fucking he is nothing."

"Qin Yu entered the factory at the time, but I helped her carry the luggage, I had a chance, but ..."

Monday, the weather is cloudy.

"Qin Yu and Zhang Huaiying divorced, especially happy, I think you can drink a cup."

"Although Qin Yu became a widow, I don’t dislike her."

"And in the past few years, Qin Yu has become more and more beautiful, full and more plump."

"I am going to send her a card today, I bought it from the department store, should she like it?"

After Wu Degui got this diary reward, Wu Degui will remember a diary at other time.

But there is no specific time record, only a few days and weather conditions.

Not only that, he did not write the frequency of the diary. After Chen Yan turned the 10 page, it was already the last diary.

"Damn Zhang Huaiying made me laid off!"

"I have a lot of my feet for the factory, and you have made me laid off!"

"You are like this, ***, no wonder Qin Yu divorced you and the director of the factory, you deserve it!"

"Zhang Huaiying, you wait, one day you will fall in my hands one day, I must put the blood of ***, so that you will never be over!"

The last diary, there is no week, there is no weather.

And it is very scribbled than ever, obviously written under the anger.

After that, there is a blank page.

Chen Yan turned around and found that there was still record on the back of the diary.

Chen Yan turned the diary in turn, opened it, his eyes condensed.

It turns out that behind the diary is the planning plan of Wu Digui to kill the taxi driver.

The first taxi driver victim: Zhang Huaiying!

The diary records every detail of Wu Degui's killing.

Including when do you do it, what to do after hand, what to use to eliminate traces, how to eliminate, how to check, etc.

Very detailed.

After that, there are five similar murder planning schemes.

The last plan, the first page drawn is the sketch of the Phoenix Street area.

Draw a red line through the red pen on the red pen.

There are also arrows marked. This route that Liu Qingshan labeled Li Yansong's taxi when reporting to the area was very similar.

"Master, look at this."

Pay the notebook to Liu Qingshan, and the latter look at it, the eyes burst out of the eyes: "How do I depend on this time!"

With those white sneakers, it can be determined that Wu Degui killed Li Yansong through the comparison of shoe printing.

But what about the previous taxi driver?

After so many years, how to find evidence?

And this diary confirmed that Wu Digui was the murderer of a serial killing case.

This involves a closed -loop of evidence detected by a case.

Whether it is clothes or shoes, it can prove that Wu Degui killed Li Yansong.

However, the evidence of the four -ring murder case from 15 years ago could not be found, so if it was determined that Wu Daigui was the murderer of a serial killing case?

It is not possible to judge according to the crime method, and even if Wu Digui admits that he is a murderer who is a serial killing, it is still impossible to support it.

Once there is no evidence, it cannot be rigorous that the serial killing case has been detected.

With this notebook, with the above -mentioned plan to plan the murder, this is called complete evidence.

The interrogation room.

This time, Chen Yan and Wang Fenglei interrogated Wu Degui together.

Just now, all the evidence has been seen for Wang Fenglei.

Now, it can be said that the evidence is conclusive!

The clothing and shoes found under the high platform have been sent to the technical group for trace identification. Only the laptop is sealed in the evidence bag and placed on the interrogation table.
