Chapter 238： combing relationships

Regarding Zhang Baoshan's investigation, the Yinglu City Detective Team does not have much information.

I just registered Zhang Baoshan's basic information, and roughly investigated Zhang Baoshan's whereabouts on the night of the 27th.

According to Zhang Baoshan, he came out for patrol around 12 o'clock that night.

However, after just walking around the factory, I went back.

In the evening, there was a security guard who drank with him, and the two slept in the duty room at the time.

"At that time, with the testimony of the security guard, Zhang Baoshan had alibi."

"So, we didn't do much research on Zhang Baoshan."

alibi?

Chen Yan frowned slightly, paused, and looked at Hu Xueying: "Captain Hu, I already have some understanding of the basic situation of the case."

"This time, as a special advisor to the Liao Provincial Detective Brigade, I am here to provide some help within my ability."

"In this way, I will make some suggestions based on the current clues, you see..."

"Don't," Hu Xueying quickly waved her hand when she heard Chen Yan's words: "Team Leader Chen, you are too polite."

"Although this case happened at the end of July last year, the serious crime team has not yet been established."

"However, the case has not been solved yet. You accept it directly. From a procedural point of view, there is no problem."

Hu Xueying looked around and continued, "Team Leader Chen, to tell you the truth, this case has put a lot of pressure on our team."

"Everyone has basically tried every trick they can think of, and they have also investigated all the information they can investigate."

"However, there was no surveillance at the scene, no witnesses, only two survivors who identified each other as the murderer."

"Team Leader Chen, please communicate with the leader of the detective team this time."

"Let's see if the serious crime team will accept this case directly?"

Take over directly?

Chen Yan frowned slightly, he just came to see and help.

Everyone has been doing bad things for nearly half a year.

It's not a good thing for Hu Xueying to take over at this time.

At the very least, the superiors should be suspicious of Hu Xueying's ability.

"Team Leader Chen," Hu Xueying saw Chen Yan's expression and thought that Chen Yan didn't want to take over: "I know that this case has passed for so long, and it is very difficult to investigate."

"It's really the problem of our detective team in Lu City, but..."

Forehead…

"Captain Hu," Chen Yan knew that Hu Xueying had misunderstood her meaning, and interrupted Hu Xueying: "You may have misunderstood me."

"It's nothing for the serious crime team to take over this case."

"I'm afraid... once we take over, will the above have any opinion on you..."

view?

Hu Xueying was taken aback.

Immediately rejoiced.

As long as Chen Yan is willing to take over this case, it is better than anything else.

"Team Leader Chen, you misunderstood!"

"I'm still worried about my opinion. As long as I can solve the case, don't say anything about my opinion, even if I'm dismissed on the spot, I have no complaints."

"And, don't worry, if this case is still not solved in the end, I, Hu Xueying, will take all the responsibilities, and I will never let the serious crime team take the blame!"

Ha ha.

"Captain Hu, what you said, if the case is not solved, you don't have to take responsibility."

"The case that I took Chen Yan has never been held accountable by others."

"In this way, since you have the idea of ​​handing over the case, I will communicate with the Provincial Detective Brigade and go through the transfer procedures."

…

The handover procedure was quick, and it was done in half an hour.

Chen Yan personally called Qin Chuan and made a report.

The formalities and so on, as long as the investigation department makes a record.

Case analysis meeting.

"Everyone, since the case has been taken over by the serious crime team, let's work hard for everyone to cooperate in the next work."

Now that it has been handed over, Chen Yan can naturally give orders directly.

"First, the interpersonal relationship of the deceased Duan Zhongxin must be carefully investigated again."

"I want to know all the resumes of the deceased over the years, including who he had grudges against, who he had financial dealings with, the specific circumstances of family members, etc., all information."

In this regard, the Yinglu City Detective Team has actually done some work.

However, it is clearly not detailed enough.

The time span of the investigation is not long enough.

The details are also lacking.

"Captain Hu, you can arrange for someone to follow up in this regard. I will give you an investigation list after the meeting."

"Yes!"

"Second, investigate all the relationships between Yu Huihui and Tang Muqi."

"Especially Yu Huihui's private life relationship and the mutual acquaintance between the two."

"For example, Tang Muqi has been there a few times before coming back to the restaurant."

"This, Captain Hu, you have already conducted some investigations, and then follow up the investigation according to the list I gave."

"The third is the investigation by the reporter Zhang Baoshan."

"Zhao Bing, take the lead in the investigation of this person."

"I want to know Zhang Baoshan's every move on the night of the 27th."

"And all the past experiences of this person, whether there is any intersection with the deceased Duan Zhongxin and the survivors Yu Huihui and Tang Muqi."

"A comprehensive investigation of Zhang Baoshan's economic situation, private life, and past work experience."

"Does anyone have a grudge, or an economic dispute, etc.!"

"Yes!"

The first case analysis meeting is over.

Hu Xueying arranged for personnel to continue the investigation and visit according to the list given by Chen Yan.

Zhao Bing also got busy and brought five local detectives to investigate Zhang Baoshan's situation in an all-round way.

And Chen Yan was also not idle.

No matter who is the murderer, Chen Yan needs to solve the first puzzle.

That is, how exactly did the murderer do the secret room murder.

…

Inside the office.

Full of photos of red brick houses.

Chen Yan observed and analyzed brick by brick.

First is the roof.

The material is old-fashioned waterproof linoleum from many years ago.

Because of the time, the edges have weathered a little.

The investigation of the red brick house by the Yinglu City Detective Team was very meticulous.

The top of the red brick house was also photographed.

The scattered red bricks are pressed on the linoleum, and the details are very clear.

The traces of the red brick pressing on the linoleum are relatively deep, and there is no trace of flipping.

The roof should have been untouched.

If the murderer manipulated the roof, it would be impossible to reproduce it so perfectly.

Traces of time are the hardest to imitate.

Then there is the wall.

In the red brick house, Chen Yan touched the red bricks on the walls. Every wall was old red bricks with a rough feel.

Moreover, all the walls have the same color and the same degree of wear and tear of the bricks, and the naked eye can directly tell whether there are new red bricks mixed in them.

On the ground, there is no problem.

The floor in the workshop is made of cement, and there are no signs of damage.

Although there is some land outside the factory, there is no trace of excavation.

The key is that the ground in the red brick house is paved with the same old red bricks as the walls.

No sign of excavation.

All that's left is the wooden door.

However, Chen Yan had already carefully observed the organization of the wooden door at the scene.

The door frame is no problem, the door hinge is no problem, and the wooden door itself is no problem.

dead end!

Lying on his back on the chair, Chen Yan frowned.

Really no problem.

The visual gene lock cooperates with the freeze frame of the picture, and Chen Yan analyzes every detail very clearly.

If the murderer started from these aspects, it is impossible to deceive Chen Yan's eyes.

Yu Huihui…

Tang Muqi…

Chen Yan is still inclined towards the possibility of the two joining hands to commit the crime.

Because, at present, it is only possible for the two to commit the crime together, and if there is someone outside to help, it is possible to create everything that is displayed at the crime scene.

As for the absence of fingerprints on the bricks, it would be easy to explain if the two committed the crime together.

Wear gloves, and of course no fingerprints will be left.

And sprayed blood.

The bloodstains that the Yinglu City Detective Team tested at that time were mainly bloodstains on their clothes.

Because the bloodstains on the skin of the two were already blurred, there was no way to collect them.

Therefore, if the two of them take off their clothes when they are killing people, put them in front of Duan Zhongxin on purpose, and then kill Duan Zhongxin with a brick.

In this way, the blood on the clothes is naturally continuous.

After the crime is over, the two can put on their clothes again to create the illusion that the on-site evidence does not match the murder of the two.

As for the outside accomplices...

Didn't Zhang Baoshan report the case?

Three people, one reported the crime, and wrapped the wooden door with iron wire outside, and two murdered in the red brick house, falsifying the scene.

Everything is flawless!

Moreover, from the current point of view, the Yinglu City Detective Team really did not spend a lot of attention on them.

Of course, this is only an inference made by Chen Yan at present.

A hypothesis based on a method of killing in a secret room, where reasoning cannot be done.

If Chen Yan can find out how the murderer carried out the murder in the secret room, then everything will no longer be true.

Yu Huihui and Tang Muqi, UU reading www. It is possible that uukanshu.com was caught by the murderer to confuse the sight.

Zhang Baoshan also really heard the vision, so he reported the case the next day.

All three are innocent.

The murderer was indeed someone else.

However, at present, when it is impossible to infer the murder method in the secret room, it can only make a fuss from these three people!

…

Just when Chen Yan deduced the case, the Yinglu City Detective Team was not idle.

According to Chen Yan's deployment, the three teams made every effort to organize the investigation.

9 pm.

Hu Xueying knocked on Chen Yan's office excitedly: "Team Leader Chen, the person investigating Yu Huihui is back."

"There is a major clue!" 18428/10568151
