On The Day Of My 100th Blind Date, I Arrested My Date

Chapter 539 Key Evidence

@@In fact, when Chen Yan taps with his fingers, it is easy to hear whether there is an empty drum under the tiles when the auditory gene lock is turned on.

It's just that if you find something like a steel bar and strike it, the sound will be easier to distinguish, even with Liu Qingshan's ordinary hearing level, you can hear it.

After a while, Liu Qingshan turned back and handed over a short steel bar to Chen Yan, leaving one in his own hand.

The bathroom is not big, and there are two walls for two people, and they start to distinguish by knocking.

Chen Yan, something seems wrong here.

There were two bricks in the middle of the south wall that Liu Qingshan was in charge of knocking, and there was a hollow sound of thumping.

Chen Yan also heard it clearly, but, just two bricks...

This range is a bit small: It is very likely that the mortar inside the tile is empty, pry it open and have a look.

good!

Liu Qingshan wasn't sure if there was something in it, or if it was just the sound of the hollow mortar, but he just needed to open it and have a look.

Snapped!

The steel bars were struck hard, and the tiles were broken. Liu Qingshan stepped forward to check carefully, and there was a concrete wall behind the tiles.

His face darkened, and Liu Qingshan looked at Chen Yan: The mortar is empty.

It's okay, try another place.

Two people knocked down the top tiles of the bathroom one by one, and found that after the 7 hollow bricks were smashed, there were cement walls inside, all of which were caused by empty mortar and no hidden spaces.

Ten minutes later, all the tiles had been tapped, but nothing was found.

Chen Yan also frowned slightly at this moment: Where else can I hide?

The bathroom in the rental house is a squatting toilet. Chen Yan stood on the countertop of the squatting toilet and searched the entire bathroom again.

At this moment, Chen Yan has activated the visual gene lock, scanning every detail carefully.

However, five minutes later, Chen Yan still had nothing to gain.

The tiled walls fit perfectly, and there was no possibility of any hidden compartments.

Could it be that he didn't put XZ here at all?

Or have things been destroyed?

destroy?

not here?

Chen Yan shook his head: Wu Degui is different from ordinary murderers. He is a serial murderer who committed five consecutive crimes.

The psychology of this kind of person is completely different from that of ordinary people.

Chen Yan pointed to the discs under the coffee table: Look at the discs there, some are new this year, and some are old discs from more than ten years ago.

However, if you look at the order in which the discs are placed, some older discs are not at the bottom, and new discs are not at the top.

There is also the disc played in the DV player, which is also a previous TV series.

Even some discs can be preserved for more than ten years. Will Wu Degui destroy the things he used to commit crimes?

As for finding another place to store it...

Chen Yan still shook his head.

Wu Degui committed a serial murder case. The things he used, the plan he planned, and even the tools he used to commit the crime, he will definitely keep it by his side, and it must be a place where he can see it all the time.

Chen Yan walked out of the bathroom while talking, and looked around the entire living room.

Just, where is this place?

That is, where can it hide?

The whole room is so big, a living room, a bedroom and a bathroom.

Liu Qingshan followed Chen Yan out of the bathroom, and followed Chen Yan's gaze to look around.

Um?

Suddenly, Chen Yan paused slightly.

At this moment, Chen Yan happened to be in front of the sofa, facing the bathroom.

A place that can be seen all the time...

Chen Yan seemed to have grasped some key information.

In the living room, the old sofa has a dent in the middle due to long-term use.

Sitting on it, Chen Yan could tell that this was where Wu Degui often sat.

Looking up, looking, the corner on the left is the TV.

A more comfortable posture to watch TV from this angle is to lean on the sofa and rest your left hand on the edge of the sofa.

However, when the statement

After sitting up straight, when looking at the head, the line of sight is facing the bathroom.

In simple rental houses, most of the bathrooms are squatting toilets.

The installation of the squatting pan is different from that of the toilet.

In fact, whether it is a squatting toilet or a toilet, except for the top, the internal structure is somewhat similar.

There is an S-shaped elbow in the water.

The S-shaped elbow of the toilet is inside the toilet, because the toilet itself has a height of 40 cm to 50 cm, so the elbow that prevents backflow can be accommodated inside the toilet.

However, squatting toilets will not work.

Due to the structure of the squatting pan, it must be installed at least 20 cm above the ground.

The reason for this is to leave enough space for the bend of the squatting toilet.

Therefore, in terms of space, squatting toilets waste more space, but the cost is cheap.

Chen Yan got up again and looked at the sofa.

This sofa is relatively small, with only two seats. Generally speaking, the sofa will be placed in the middle of the living room, which is in line with the aesthetic thinking of most people.

However, the sofa in Wu Degui's house is placed a bit to the left.

That is, near the window sill.

In Wu Degui's room, after entering the door, there is a bathroom behind, that is to say, the bathroom is near the window sill.

What puzzled Chen Yan was, why didn't Wu Degui put the sofa in the middle?

Instead, it is on the left, and you can see the toilet when you look up.

This is not in line with the preferences of ordinary people.

Generally speaking, staying away from the toilet is the right thing to do.

There is only a coffee table in Wu Degui's room, and there is no dining table, which means that he should most likely eat on the coffee table when he usually eats.

So Wu Degui looked up at the toilet after eating?

Isn't this a bit strange?

Chen Yan sat on the sofa, staring at the toilet...

The visual gene lock is on!

Um?

Soon, Chen Yan discovered something was wrong.

A tile facing Chen Yan had a slightly different edge color from Zhou Wei's.

It seems that it is smoother and more reflective!

Chen Yan immediately got up, bent down, squatted at the door of the toilet, picked up the steel bar at hand, and lightly tapped the floor tile on the side of the squatting toilet platform facing him.

Boom boom boom!

The hollow sound is very clear.

Chen Yan changed direction and tapped on other floor tiles.

Boom boom boom!

It was still a hollow sound.

Liu Qingshan naturally heard something was wrong, with a surprised expression on his face: The bottom is empty?!

Gan!

Now that an exception is found, it is convenient to open it.

Chen Yan just gently pushed the edge of the floor tile facing him just now, and with a little force, the floor tile was taken off in one piece.

Flashlight!

After receiving the flashlight from Liu Qingshan, Chen Yan lay down on the ground and shone inside.

At the same time, there was a pungent smell of blood and the familiar smell of Li Yansong.

Finally found!

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

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

In addition, Chen Yan and Liu Qingshan also found a box of probes and a rubber tube several meters long.

Besides these, there is also a notebook.

Liu Qingshan immediately picked up the white sneakers, looked at the pattern on the bottom, and it was exactly the same as the shoe prints extracted from his memory: It's these shoes!

Because of the different degree of wear and tear of each pair of shoes, even if it is the same person, the shoe prints left by wearing them in different periods are unique.

Therefore, in principle, as long as there are these shoes, the evidence that Wu Degui killed Li Yansong is conclusive.

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

While Liu Qingshan was arranging the clothes Wu Degui wore when he murdered, Chen Yan took the black leather notebook.

notebook lettering is debossed on the black cover

The corners have turned yellow, and the black cover is also a little worn.

In Chen Yan's memory, this style of notebook should have been produced more than ten or twenty years ago.

But judging from the degree of curling at the corners and the wear and tear on the top, its owner obviously flipped through it a lot.

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

Prizes: Wu Degui was awarded the title of Difficult Truck Transport Model, and was awarded a notebook as encouragement.

The signing unit, the first transportation company of Shenyang City, was signed in 2001.

This is……

Something from twenty years ago.

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

At present, it is only known that Wu Degui's household registration is in Shenshi City, but no real estate has been found under his name.

There is no information about his marriage, and the household registration information is relatively simple.

And the people in this compound are not very familiar with Wu Degui, and they don't know anything about his past.

The First Transportation Company of Shenyang City...

It turned out that Wu Degui had worked in Shenshi No. 1 Transportation Company.

The First Transportation Company has been established for a long time, with a history of about 70 or 80 years, but it closed down 20 years ago due to changes in the economic development model.

The company was restructured into Shenshi Public Transport Group Company.

Master, wait to go to Shen City Public Transport Collective Company to check the archives of Shen City No. 1 Transport Company. Wu Degui once worked in this company.

See if we can find anything.

good!

Liu Qingshan agreed to come down and arrange relevant work immediately.

Chen Yan continued to read the diary.

First page.

On Monday, the weather is light and rainy.

Lao Li paid 1 yuan and 50 cents last month. He promised to give it to me today, but he didn't.

How could I have lent him the money? Old Li is famous for deducting money. I probably won't be able to get back the 1 yuan and 50 cents.

It's really not good, tell him, but we are all colleagues, because it's not good to lose face because of 1 yuan and 50 cents.

Forget it, I don't want the money, just puncture the rear tire of his bicycle.

Wednesday, the weather is fine.

Today at noon, I saw Qin Yu eating at the entrance of the cafeteria again.

Qin Yu is really good-looking, but it's a pity that he flattered Zhang Huaiying.

Don't you just know how to flatter the leader? If you become a director, otherwise he's nothing.

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

On Monday, the weather was cloudy.

Qin Yu and Zhang Huaiying are divorced. I'm very happy. I think I can have a drink.

Although Qin Yu has become a widow, I don't despise her.

And in the past few years, Qin Yu has grown more and more beautiful and plump.

I'm going to give her a hairpin today. I bought it from a department store. She should like it, right?

After Wu Degui received the reward for this diary, Wu Degui would write a diary every once in a while.

But there is no specific time record, only the day of the week and the weather conditions.

Not only that, but the frequency of his diary writing is not high. After Chen Yan has opened about 10 pages, it is already the last diary entry.

Damn Zhang Huaiying, let me be laid off!

I'm crippled because of the factory, and you let me be laid off!

You flatterer, shit, no wonder Qin Yu divorced you and went with the factory manager, you deserve it!

Zhang Huaiying, you wait, sooner or later you will fall into my hands, and I will definitely bleed your mother's blood so that you will never be reborn forever!

Diary for the last time, no day of the week, no weather conditions.

And compared to the past, the handwriting is very scribbled, obviously written in a rage.

After that, it's a blank page.

Chen Yan flipped through it casually, only to find that there were records on the back of the diary.

Chen Yan turned the diary over and opened it, his eyes fixed.

It turned out that what was recorded behind the diary was Wu Degui's plan to kill the taxi driver.

The first taxi driver victim: Zhang Huaiying!

The diary recorded every detail of Wu Degui's murder.

Including when and where to do it, what to use to remove the traces after doing it, how to remove it, how to check it, etc.

Very meticulous.

After that, there were five similar murder plans.

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

A red line was drawn with a red pen to cross the roads in the area.

There is also an arrow mark, which Liu Qingshan marked in the report that the route of Li Yansong's taxi after entering the area is very similar.

Master, look at this.

Handing the notebook to Liu Qingshan, the latter looked at it, and his eyes burst into light: Now I see how he can deny it!

With the pair of white sneakers, it can be confirmed that Wu Degui killed Li Yansong through the comparison of shoe prints.

But what about the former taxi driver?

So many years have passed, how to find evidence?

And this diary confirmed that Wu Degui was the serial murderer.

This involves a closed-loop issue of evidence for case detection.

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

However, the evidence of the four serial murders 15 years ago has long been found, so if it is determined that Wu Degui is the murderer of the serial murders?

Judging by the modus operandi is not acceptable, and even if Wu Degui admits that he is a serial murderer, it still cannot be supported without evidence.

And once there is no evidence, it cannot be said rigorously that the serial murder case has been solved.

With this notebook and Wu Degui's plan to kill him, the evidence is complete.

trial room.

This time it was Chen Yan and Wang Fenglei who interrogated Wu Degui together.

Just now, all the evidence has been shown to Wang Fenglei.

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

The clothes and shoes found under the high platform of the squatting toilet have been sent to the technical team for trace identification. Only the notebook is sealed in the evidence bag and placed on the interrogation table.

Wu Degui, do you think we will never find what you hid?

Clothes, shoes, notebook, probes, rubber hose, and a bottle of ether spray.

These are all Wu Degui's crime tools.

At this moment, Wu Degui was shaking like a sieve.

His eyes stared in horror at the black leather notebook on the table.

It seemed to be murmuring subconsciously in his mouth: Impossible... Impossible... How can you find it?

Wu Degui!

Wang Fenglei let out an angry roar, which made Wu Degui startled: Say, how did you kill five taxi drivers?

Zhang Huaiying let you lay off, you can say that you killed him to get revenge on him, but what about the other four?

Why did you kill them!

The information about Wu Degui back then has also been investigated clearly.

At that time, Wu Degui was very active in the Shenshi No. 1 Transportation Company, and basically got advanced every year.

But at the age of 23, because of repairing the vehicle, his left foot was smashed by the engine, and he became disabled.

In addition, this person is dull and introverted, so he never found a wife until he was laid off eighteen years ago.

And Zhang Huaiying lost her public office 15 years ago because of corruption and bribery, and started driving a taxi in the society.

After Wu Degui learned about it, he planned to kill Zhang Huaiying.

This was the first serial murder of taxi drivers fifteen years ago.
