Chapter 172： Clue convergence

Zhang Yaoming also followed Chen Yan into the temporary plastic shed.

"Song Pengcheng's mother... It's only been 4 days since he passed away. Why did he return to Feng County at this time?"

It is a custom among Dan people that the first seven days after the death of the parents, the children should observe filial piety in front of the spirit.

Chen Pingping died of spontaneous combustion on the 22nd, and today is only the 26th.

It stands to reason that at this time, Song Pengcheng should guard his mother's spirit in Dan City, and should not return to Feng County.

"Oh, that's what I asked," Lin Hao nodded. "Song Pengcheng just came back from Dan City this morning, and it's been a few hours since he arrived at the hospital."

"There is an important operation in their hospital today. Song Pengcheng is the chief surgeon."

"The Fengxian Hospital knows about Song Pengcheng's situation, so I called for his opinion."

"However, Song Pengcheng said that the operation time is not long, and if this patient's operation is not performed today, the previous preparation work will be done in vain, and it will not be good for the patient's health..."

...

After entering the plastic shed, Chen Yan immediately opened the olfactory gene lock and the visual gene lock.

Slightly twitching his breath, the surrounding smell immediately appeared in Chen Yan's mind.

A strong odor of carbonation permeated the entire shed.

On the ground, there were only half charred corpses.

The upper body has been completely carbonized, only the lower body is still there.

However, the lower part of the calf had burned away, leaving only half of the carbonized bone **** exposed.

In addition to the rich coke smell, there is also a hint of sweetness.

The unique smell after the protein is burnt, similar to the aroma of cooked skewers.

It is the taste of human flesh after it is cooked.

At this moment, half of the corpse still has a certain temperature. After Chen Yan approached, he could feel a slight heat blowing towards his face.

Besides, there are some other details,

First of all, most of the half corpses were blackened, but there were a few spots with very obvious burn marks.

It seems that the burning of the entire corpse starts from these points.

Spread from point to surface.

At the same time, some finely divided metal powder can be observed, appearing on the body.

"Did the deceased have an umbrella at the time?" Chen Yan used a special probe to gently touch the obvious burn marks on the corpse.

Lin Hao nodded: "The place where the deceased happened is right at the door of the hospital, and there are surveillance videos."

"The video shows that Song Pengcheng is indeed wearing an umbrella, and..."

"And what?"

Lin Hao looked at Zhang Yaoming with a strange expression: "The umbrella used by Song Pengcheng... is also brand new!"

Also a new umbrella?

Zhang Yaoming's heart suddenly trembled.

Is this eucalyptus really related to umbrellas?

Li Wei, Chen Pingping, Wu Jianguo, and now Song Pengcheng.

All four of them used new umbrellas when they spontaneously ignited.

In this way, the possibility of coincidence... getting smaller and smaller.

After a while, Chen Yan finished his observation.

"I want to look at the surveillance video, and also, the witnesses and security guards at the time, I want to ask some things in person."

Lin Hao nodded and made arrangements immediately.

Chen Yan, who walked out of the plastic shed, had a solemn expression and frowned.

At the scene of the eucalyptus this time, Chen Yan discovered many details.

Unlike the first three dead, after being completely burned, only a pile of ashes are left behind.

Moreover, Chen Yan explained why the deceased was able to spontaneously ignite, and why it specifically ignited on rainy days.

There is even some speculation as to why the heavy rain could not extinguish the burning body of the deceased.

There is also a little inference why all four of them are holding umbrellas, and it is a new umbrella.

However, these guesses and inferences need to be corroborated.

Fengxian Hospital Security Room.

On the large screen of the monitor, Song Pengcheng's natural picture is playing.

The video camera is mounted on the wall above the hospital gate.

Looking down, looking down.

12:17.

A man walked out of the hospital building with an umbrella.

"This is Doctor Song."

The security captain on the side immediately pointed out to Chen Yan and others who was Song Pengcheng.

In addition to Song Pengcheng, there were two people walking out together.

One of them was wearing an umbrella, the other was wearing a raincoat.

The video continued to play, and Song Pengcheng walked to the parking lot.

"Song Pengcheng had completed the operation at this time, and was about to drive back to Dan City. As a result, an accident happened at this time."

As soon as Lin Hao finished speaking, Song Pengcheng in the video suddenly stopped slightly, and then the fire filled the air.

The fire seemed to rise out of thin air and engulfed Song Pengcheng in an instant.

The umbrella turned to ashes immediately, and it was visible to the naked eye that Song Pengcheng's upper body and lower body were on fire at the same time.

In just two minutes, the person was already exhausted and fell to the ground.

At this time, the security guard in the building rushed out with a fire extinguisher and sprayed it towards the place where Song Pengcheng caught fire.

However, the fire was still so large that the fire extinguisher didn't seem to work at all.

It was not until the other two security guards rushed out and the three fire extinguishers worked at the same time that the flame was finally extinguished.

Video ends.

"Chen team, this is the whole process of the eucalyptus."

The pictures in the video are clearer than when Li Wei, Chen Pingping and Wu Jianguo died of spontaneous combustion.

After all, it was daytime, and the surveillance cameras of Fengxian Hospital had higher resolution.

In the drizzle, Song Pengcheng was using a brand new blue umbrella.

In Chen Yan's mind, frame after frame flashed.

Li Wei, Chen Pingping, Wu Jianguo, and this Song Pengcheng.

The pictures of the same parts in the four videos are all compared in Chen Yan's mind.

He's trying to find what the four have in common.

Mostly small details.

For example, is there anything special about the way of holding an umbrella?

Li Wei holds an umbrella in his right hand, as does Chen Pingping.

However, Wu Jianguo and Song Pengcheng are holding umbrellas in their left hand.

This...has nothing in common.

Another example is the expressions of the people around at that time.

Li Wei spontaneously combusted because there was no one around, but the other three were spontaneously combustible, and there were witnesses.

Everyone's expression ranged from surprise to disbelief, as well as fear.

However, there was no schadenfreude or indifference that Chen Yan had predicted.

Spontaneous combustion, anyone who can see it, will definitely have a great stimulation and change in the eyes and expressions.

And once there are people who are watching from the sidelines, then there must be a problem.

But……

No.

The expressions of witnesses, although different, can all reflect drastic emotional changes.

After a long while, Chen Yan looked away from the monitor screen.

Four people have one thing in common.

And not just in one place.

However, nothing new was discovered.

"Team Chen, how's it going?" Zhang Yaoming's mind is now dazed.

four people!

This is four people.

Just now on the road, Qin Chuan called directly to ask about the specific situation.

Therefore, Zhang Yaoming is very anxious now.

This is all happening on the territory he manages.

Not to mention that the eucalyptus can't be broken, his hat is not there.

How did he give an explanation to the deceased and the family of the deceased?

Spontaneous combustion incidents occurred one after another, and any fool knows that this is not a coincidence.

"It's the same as the three previous cases."

Chen Yan pointed to the figure on the video: "The umbrella of the deceased Song Pengcheng is brand new."

"Also, look at the leather shoes on his feet. They are also old shoes, but they have just been repaired. The spikes on the heel of his left foot are brand new."

Zhang Yaoming nodded.

He had just discovered this.

Chen Yan had just arranged for Wang Xiurui and Lan Feng to investigate the umbrella and shoe repair, so after seeing the video, Zhang Yaoming took a closer look at Song Pengcheng's umbrella and shoes.

"Lin Hao, when Song Pengcheng spontaneously ignited, the security guards who put out the fire for him called over and I asked for some details at the time."

Lin Hao nodded: "The three security guards are all next door, so I'll arrange it."

...

Chen Yan handed a cup of hot water to the security guard: "Don't be afraid, what to say."

"At that time, how did you find out that Song Pengcheng was on fire?"

Wang Jie, the first security guard who found out that Song Pengcheng was on fire, rushed out of the hospital door and took a fire extinguisher to put out the fire for Song Pengcheng.

At this moment, holding the hot water handed over by Chen Yan, his body is still a little trembling.

"Doctor Song... It was Dan City's No. 1 Hospital who supported us here. His medical skills are very good..."

"I...my dad's surgery was done by Dr. Song..."

"At that time, when Dr. Song went out, I took two steps away, and he said hello to me..."

"Who would have thought that as soon as we went out,..."

Wang Jie's voice was a little sloppy at first, but then slowly began to become fluent.

"Can you tell me what happened when you first saw Dr. Song on fire?"

Although Chen Yan watched the four videos of the four spontaneous combustion, all the video angles were shot from top to bottom.

Moreover, the four were all holding umbrellas at the time, so Chen Yan had never seen the expressions of the four at the time.

In other words, Chen Yan did not see the initial stage of the specific fire.

All were blocked by umbrellas.

By the time the umbrella was burned, the fire had already started and nothing could be seen.

Including Sister Liang who witnessed Chen Pingping's spontaneous combustion.

However, she and Chen Pingping were advancing side by side, and she suddenly felt a scorching wave coming from her side, so she turned to look at Chen Pingping.

At this time, Chen Pingping was already on fire.

The same goes for the two eyewitnesses who saw Wu Jianguo set on fire.

When looking at the past, Wu Jianguo has turned into a ball of fire.

Under the intense burning, after a few minutes, it became a pile of ashes.

Hearing Chen Yan's question, Wang Jie Tong Kong shrank slightly uncontrollably: "At that time, I was watching Doctor Song out of the hospital gate."

"As a result, when he was walking down the steps to the parking lot, it seemed like a fireball fell from Doctor Song's head."

"Then... all of a sudden, Doctor Song burned in the white light."

"I was so frightened at the time, I was stunned for a while, then I picked up the fire extinguisher beside me and rushed out."

"But...it's too late..."

"The fire on Dr. Song's body was very intense. Before I got to him, I felt a particularly hot heat wave coming towards him."

"At that time, I turned on the fire extinguisher and sprayed Doctor Song..."

"But it doesn't seem to work at all..."

"If it wasn't for Mr. Zhang and the others who came to help, the fire wouldn't be extinguished at all."

Although Wang Jie was a little nervous, his words were logically accurate.

From the discovery of Song Pengcheng's fire to the extinguishing of the fire, as well as some details in the middle, the descriptions are all in place.

Especially in the initial stage when Song Pengcheng's body caught fire, Chen Yan's eyes lit up.

This was the first time for him to learn about the first thing that happened when the four people's bodies caught fire.

"Wang Jie, did the light rain outside have any effect on the fire?"

"Yes," Wang Jie nodded, waving his arms and drawing in a circle: "When the fire started, the rain seemed to follow."

"The first time I saw it, the more the rain fell, the bigger the fire."

"After a while, in the blink of an eye, that Doctor Song was almost burned out."

It seemed that he remembered the situation at the scene again. Wang Jie spoke very quickly and was a little trembling.

"Wang Jie, did you hear Doctor Song shouting when you went out?"

Wang Jie thought for a while: "That's not true...but the door was open at that time. If Doctor Song shouted, I should be able to hear it."

Chen Yan nodded.

At the scene of Li Wei's spontaneous combustion, there were no witnesses, so it was impossible to restore the sound at that time.

However, when Chen Pingping and Wu Jianguo ignited spontaneously, witnesses responded and did not hear any shouting.

this……

It's rather strange.

Even if the burning was very fast at that time, it was impossible to destroy the vocal cords in an instant, so that the three of them could not make a sound.

Also, what is the first reaction when a person catches fire?

As long as you don't die, your first reaction is to put out the fire.

So, it will definitely fall to the ground, roll, and try to put out the flames on him.

However, the four deceased did not respond when the fire was on.

It was as if the flames had already burned inside their bodies.

Being attacked in an instant destroyed their vitality and took their lives.

However, this does not conform to the characteristics of Song Pengcheng's death.

The scene of Song Pengcheng's death shows that his flames are from outside to inside.

Song Pengcheng's remaining body is carbonized on the surface, but the internal flesh and blood tissue is still there.

Next, Chen Yan listened to the other two security guards, as well as the two who walked out of the gate with Song Pengcheng and witnessed the whole process.

It is basically consistent with Wang Jie's statement.

It's just that they have been paying attention to Song Pengcheng without rain, so they are not as detailed as Wang Jie in the description of the initial stage of the fire.

Even the two people who were with Song Pengcheng didn't even see how Song Pengcheng caught fire.

By the time they found it, the umbrella had been burned out.

three hours later.

Song Pengcheng's body has been sent to the technical department for an autopsy.

Chen Yan followed the whole process, and before leaving, he made a special explanation to the autopsy staff.

Returning to the Dan City Detective Team, it was already evening.

It was drizzling in Feng County, and the weather in Kedan City was just right.

At dusk, the sun scatters through the windows, giving the entire conference room a golden layer.

"Team Chen, Lan Feng's investigation has made progress!"

...

The second eucalyptus analysis meeting.

Kacha.

There are three photos on the screen.

"Team Chen, we have completed the tracking of the umbrellas used by the three deceased."

Lan Feng is reporting the results of the investigation.

"The umbrella used by Li Wei is a Sunshine umbrella, and the manufacturer is located in Dan City."

"Sunshine umbrellas have the largest market share in Dan, and basically every store sells them."

"We visited the sunshine umbrella manufacturer based on the clues in the video."

card wipe.

Switch the screencast photo: "This is the same batch of umbrellas that Li Wei used. A total of 50,000 umbrellas were produced."

"It started selling last summer."

"Until now, there is still circulation in the market."

"So, it's hard to track down this direction..."

Chen Yan and the others nodded.

Sunshine Umbrella, Chen Yan knows this brand.

Even the city has it for sale.

After he came to Dan City, the umbrella he used was also a Sunshine umbrella.

Good quality, cheap price and nice style.

Very popular with locals.

"Next, we visited Li Wei's wife."

"I asked about the origin of this umbrella, but Li Wei's wife said that Li Wei had not bought an umbrella recently."

"She has never seen Li Wei before, and has used a similar new umbrella before."

Zhang Yaoming frowned: "That is to say, Li Wei got this umbrella while working in the funeral home?"

Lan Feng nodded: "Li Wei has been working as a security guard at the funeral home for many years."

"But, he's not like other security guards."

"We found during our visit today that Li Wei has a separate dormitory in the funeral home."

"Instead of sleeping in the Chase shop like other security guards."

"According to the person in charge of the funeral home, the former Li Wei was a crematorium operator, and the funeral home had the best salary."

"It's just that five years ago, he voluntarily applied to leave and became a security guard, but some treatment must have been reserved."

Chen Yan nodded, this Li Wei is a regular employee of the funeral home, and he is naturally different from the recruited security guard: "The funeral home said nothing, why is this Li Wei working as a security guard?"

Lan Feng looked at Chen Yan and nodded: "I probably asked, it seems to be because of an incident ten years ago."

"What's the specific situation?"

"Oh, it's like this. Ten years ago, this Li Wei was reported by someone for drinking alcohol during work, which almost caused a work accident."

ACCIDENT?

"What accident?"

"Actually nothing, Li Wei's colleague reported that Li Wei burned a living person in the crematorium..."

living person?

Great practice of living people?

Zhang Yaoming frowned: "What's the specific situation?"

Lan Feng operated the computer and retrieved some materials from another folder: "I was also quite surprised at the time."

"If Li Wei really made this kind of work error back then, how could he continue to work in the funeral home."

"So, I checked the data of that year."

It turned out that what happened back then was actually a misunderstanding.

Ten years ago, a deceased was sent to a funeral home.

The whistleblower said that the deceased was still alive, but Li Wei pushed him into the crematorium.

Immediately call the leader.

However, when the leader came, the cremation was almost over.

Moreover, the deceased's death certificate and other procedures were complete at that time.

There is no possibility of suspended animation at all.

"Later, the whistleblower was punished because he had no factual basis."

"Then, what does this have to do with Li Weigan's security?"

Chen Yan frowned slightly.

Lan Feng switched projections again: "It's still because of the whistleblower."

"Although the matter has passed and has been determined, the whistleblower of the year brought it up when he was drunk."

"Every time I have to go to Li Wei theory, then, after a few years, Li Wei simply quit and went to the door as a security guard."

"Okay, continue to talk about the investigation of the umbrella just now."

Zhang Yaoming looked at Chen Yan and found that the other party did not ask any more questions, so he signaled Lan Feng to continue reporting on the umbrella.

"Yes, Team Zhang!"

"We visited Li Wei's colleagues and asked about umbrellas."

"However, these people don't know the specifics."

"It's still the security guard on duty with Li Wei and told a situation."

"Everyone see..."

Lan Feng started playing a video.

"This is the surveillance video of the duty room of the funeral home, which is the video that captured Li Wei's spontaneous combustion."

"On the 18th, the day before Li Wei's accident, it was 3:28 pm."

"Li Wei answered a call, walked out of the duty room, and left the surveillance area."

"After 15 minutes, Li Wei returned to the duty room again, here..."

Video pauses, zooms in.

"At this moment, Li Wei has a bucket of oil and an umbrella in his hand!"

found it!

The video is enlarged, and the color and style of the umbrella can be seen more clearly.

On the 18th, it did not rain in Dan, and the picture in the video was clear.

Sure enough, this investigation direction is useful.

Zhang Yaoming's expression was excited, and his eyes lit up when he looked at the video.

"Team Chen, next, as long as we find out who gave Li Wei the umbrella and who called Li Wei, then there may be a major discovery!"

Chen Yan nodded.

Seeing this picture, Chen Yan was also a little excited.

In the morning, when Chen Yan arranged his work, the main consideration was the probability of coincidence.

Three people, at the time of spontaneous combustion, no, now there are four people using new umbrellas at the same time, what is the probability of this?

According to common sense, it is basically impossible.

Therefore, Chen Yancai decided to pursue this direction.

In the afternoon, at the scene of Song Pengcheng's death, Chen Yan further confirmed that his detection direction was correct.

Because, about the spontaneous combustion of the human body, Chen Yan basically has a speculation.

Now, just waiting for Song Pengcheng's autopsy results to prove Chen Yan's thoughts.

The umbrella is the most important part of it.

However, relying on this alone to find the murderer, Chen Yan is not optimistic.

Since the other party can plan such a bizarre spontaneous combustion death, how can it be possible to lock the other party just through an umbrella?

really.

Lan Feng looked at Zhang Yaoming and operated the projection: "Team Zhang, we have already started an investigation in this regard."

"It was the courier who called Li Wei that day, and we have found him."

"The other party just took the order normally, and brought oil and umbrella to Li Wei. I don't know anything about the other situation."

Forehead……

In this case……

Is the thread just cut off?

Chen Yan looked at Lan Feng at the moment: "Why didn't this courier deliver things at the door of the funeral home, but called Li Wei and asked him to go out to pick it up?"

"I asked about this too, and he said it was Li Wei's request."

"The funeral home does not allow the security room to receive couriers, so Li Weicai asked him to wait on the side of the road."

Chen Yan glanced at Lan Feng, and secretly said that it was true.

Since the other party was able to plan such a bizarre spontaneous combustion incident, his mind must be very delicate and very cautious.

However, as Chen Yan believes in, if you want people to not know, you must do it yourself.

As long as you do, you will definitely leave a clue.

"Captain Lan Feng," Chen Yan looked at Lan Feng: "Chen Pingping and Wu Jianguo's umbrella, what's the progress?"

"Have!"

Lan Feng's answer was unequivocal, which shocked everyone's spirits.

"The umbrella used by Chen Pingping is the umbrella of paradise."

"This kind of umbrella is rarely sold in Dan City. We checked and only five stores are selling it."

"However, we checked the recent videos of relevant stores and found no record of Chen Pingping's purchase."

"Moreover, we have also compared Chen Pingping's online shopping records, and we have not found any records of her online purchases."

"However, according to Chen Pingping's husband's recollection, Chen Pingping brought the umbrella back from outside on the 20th."

"Because Chen Pingping has a lot of umbrellas at home, at that time, Chen Pingping's husband asked specifically, but Chen Pingping did not say how it came from."

"I just said one sentence anyway, I didn't spend any money, so don't worry about it."

"As for Wu Jianguo's umbrella, it's the umbrella configured in the nursing home."

"We visited Wu Jianguo's office director. He said that the umbrella Wu Jianguo used was the umbrella in his office."

"It was distributed by the nursing home after a unified purchase last month."

Uniform distribution, a month ago...

Zhang Yaoming frowned: "Is the umbrella in Wu Jianguo's office...is it still there?"

Lan Feng shook his head: "We've already checked and it's not there."

The clues about the umbrella are basically collected.

I have to say that Lan Feng's ability to handle eucalyptus is really good.

In less than a day, the three deceased's use of umbrellas was basically the same.

"Team Chen, look, now..."

Zhang Yaoming looked at Chen Yan. Now that the clues have been gathered, the following is the work deployment.

"Captain Lan Feng, you have worked hard." Chen Yan got up and looked at Lan Feng's group.

"The clues of the umbrella are relatively detailed. They gave us the next step and named the direction."

Chen Yan paused, then got up and walked to the whiteboard.

Pick up the pen and write the word "Umbrella" on the whiteboard.

"Everyone should have heard that just at noon today, another spontaneous combustion incident occurred in Feng County."

Katcha, Projection Change.

It's Song Pengcheng's photo.

"The deceased, Song Pengcheng, died in a strange spontaneous combustion at the entrance of Fengxian Hospital."

"The death process is highly similar to the spontaneous combustion process of Li Wei and other three people."

"Moreover, after preliminary investigation, the deceased Song Pengcheng is the son of Chen Pingping, the second deceased."

"From the 19th to the present, the 26th, the middle, the 22nd, and the 24th, there is a spontaneous combustion incident every day!"

"Among them, there is actually a mother and son!"

"Preliminarily, we can conclude that this is a well-planned, insane, intentional murder case."

"Moreover, the murderer even attacked Chen Pingping and Song Pengcheng's mother and son in succession, so it is very likely that he has a grudge relationship with the two victims."

"From this reasoning, the murderer and the other two may also have a grudge relationship."

"So, at present, our investigation direction is not too deviated."

"The clues about the investigation of umbrellas and shoes have already begun to emerge. Combined with the scene of Song Pengcheng's death, I already have some speculations about the principles of these four spontaneous combustions."

"Now, only after Song Pengcheng's autopsy report comes out, we will be able to testify."

"So, everyone, don't be discouraged, and build your confidence."

"The truth is getting closer and closer to us."

"Next, I'll arrange the next step."

"First, Lan Feng's group is looking for where the edible oil given to Li Wei was sold."

Kacha.

The projection switching is exactly what Lan Feng showed to everyone, Li Wei carrying cooking oil and an umbrella under surveillance.

"The umbrella in Li Wei's hand, now, there is a high probability that it was passively given to hands and feet, but it is difficult to trace the source."

"However, let's take a look at the cooking oil in Li Wei's hands."

"Basan edible oil!"

"This brand of cooking oil, I saw a billboard in the car at noon."

"Dan City's specialty, and it just got new packaging."

"This kind of edible oil is usually sold in supermarkets or specialty stores."

"Check to see if you can trace the source and find the buyer based on the batch number and other characteristics."

Lan Feng nodded: "The edible oil is still in Li Wei's dormitory, we will try our best to trace it."

Chen Yan nodded: "Second, follow up the whistleblower who reported Li Wei's work mistakes and burned living people."

"It's been ten years since the incident happened, and the other party refused to forgive him. There may be some inside information here."

"Find out the relationship between the two, and if necessary, directly subpoena for inquiries."

"Yes!" Lan Feng stood up and answered.

Chen Yan turned his head and looked at Zhang Yaoming: "Team Zhang, arrange another group of people to follow up with what Liang Huifang said about Yun Guifang's situation."

"The grievances between Yun Guifang and Chen Pingping have a long history. There are both old hatreds in the past and new hatreds in recent years when Chen Pingping's son pushed Yun Guifang's son to join the First Hospital."

"And now, Song Pengcheng has been killed again, and Yun Guifang's family is the focus of the current suspicion."

Zhang Yaoming nodded.

When visiting Liang Huifang, it was Zhang Yaoming who accompanied Chen Yan.

The specific situation, he is very clear.

"The third is the situation on Wu Jianguo's side."

Chen Yan looked at everyone: "The umbrella Wu Jianguo used was uniformly distributed by the nursing home."

"According to Captain Lan Feng's investigation results, the umbrellas in Wu Jianguo's office were never used between the time they were distributed and the day Wu Jianguo used them."

"check!"

"Lan Feng, find out who has access to Wu Jianguo's office, and who might have access to that umbrella."

"Focus on the period after the umbrellas are distributed."

Because, according to Chen Yan's judgment, the distribution of umbrellas is random, and the possibility of the other party's manipulation is relatively small.

However, when things were distributed to Wu Jianguo, most people would not touch them.

After all, Wu Jianguo is the dean of the nursing home. Who under his command has nothing to do with the boss?

"Fourth, include Song Pengcheng into the scope of the investigation at the same time."

Chen Yan looked at Lan Feng again: "Your group will continue to follow up and investigate the origin of the umbrella used by Song Pengcheng."

"Finally," Chen Yan looked serious and looked at Zhang Yaoming: "Team Zhang, we need to arrange manpower to search the homes of Li Wei, Chen Pingping, and Wu Jianguo."

"Including the residences of their children in Dan City, especially the umbrellas they use, as well as shoes, to carry out careful inspections."

...

It is already late at night to arrange this stage of deployment.

Chen Yan, who was slightly tired, returned to the dormitory arranged by the Dan City Detective Team.

Subconsciously took out his mobile phone and looked at Miss Yu's WeChat profile picture, Chen Yan only felt happy.

"Baby Yunyun..."

"Guess where I am?"

"It's not on the bed, it's under the bed...hehe!"

Sending a grimace message, Shen Yunyi's WeChat to Chen Yan will always be answered in seconds.

This, Chen Yan thought it was amazing.

Isn't Ms. Xiayu not working?

Can you see your WeChat every time?

In fact, what Chen Yan didn't know was.

When Chen Yan is on a business trip, Miss Yu will set Chen Yan's WeChat alert tone as a special ring tone.

Whether in a meeting or a guest, the phone will never be set to vibrate.

Everything has to make way for Chen Yan.

In Xiao Yu's heart, Chen Yan's priority is always the first.

Looking at the screen, Sister Xiaoyu sent a message, and the corners of Chen Yan's mouth twitched slightly.

Isn't it.

If it's not on the bed, it must be under the bed.

"But, I don't want to go to bed now, I just want to go up the mountain..."

At this moment, Miss Yu is lying on the bed.

Under the silk pajamas, there is a convex and concave figure.

His long black hair was scattered by the pillow, and he looked at the screen of his mobile phone with a silly smile.

Less domineering of the queen, and more cuteness.

Gan!

The **** charm...

"Fool, I don't want to accompany you to climb mountains, tired back pain..."

After the couple chatted sweetly, Chen Yan made a video call, looked at Miss Yu's clothes, and almost ran back.

...

Early the next morning.

The weather in Dan is a little gloomy.

It looks like it's going to rain again.

However, after coming to the conference room, Chen Yan was in a better mood.

Because, Lin Hao's investigation results came out.

"Team Chen, in the past two days, we have checked the whereabouts of Li Wei, Chen Pingping and Wu Jianguo within three months."

Kacha.

Screen switching.

is a graph of three trajectories.

"We got in touch with the communications department and retrieved the traces of the three mobile phones."

Chen Yan nodded.

The mobile phone trajectory, to a certain extent, represents the whereabouts of the mobile phone owner.

However, it is not precise.

In this way, the mobile phone can be moved to an area of ​​the connected base station.

In this way, points can be marked on the map.

However, the coverage of a base station, even if it is limited, is relatively small when it comes to people.

However, it is a good way to exclude.

"Because the recent trajectories of the three people are difficult to determine specifically through interviews."

"With this method, we first did the exclusion."

Kacha.

The photos on the projected screen are switched again.

Lin Hao pointed to the picture and continued to report: "This is the three of them. There are two places where they may overlap."

What Lin Hao did was actually to compare all the base stations linked by the three mobile phones.

If the mobile phone is linked to the base station and there is no overlap, then there is basically no space possibility for them to overlap.

"These two points, one is Times Square and the other is Victory Road."

"This is specific information."

On the screen, the projection is the specific time when the three people have been to these two places.

On September 10 and 15, Chen Pingping went to two places respectively.

"We reviewed the surveillance at that time, and Chen Pingping Square was going to dance square dance."

"Victory Road is the only way for Chen Pingping to go home from the square."

"The other two people passed by the square and Shengli Road, and there was no sign of staying for a long time."

"So, we preliminarily determined that these three people have no direct contact history."

"How are their medical conditions?"

In fact, Chen Yan did not have particularly high hopes in this regard.

After all, there is a big gap between the occupations and living environments of the three of them.

Not knowing is normal.

"Li Wei has no medical records in the past three years."

"Chen Pingping did. They were all in the First Hospital."

"Wu Jianguo had a minor operation in the past two years, but it was done in Shen City, and there is no medical record in Dan City."

"However, Wu Jianguo has a physical examination record in the First Hospital. It has been ten years and he is in the physical examination department."

Chen Yan frowned: "That is to say, in terms of medical history, they have never met?"

Lin Hao nodded: "Team Chen, it looks like this at the moment."

"How about other relationships? For example, do Li Wei and Chen Pingping have relatives in Wu Jianguo's nursing home?"

"Chen Pingping or Wu Jianguo, have any deceased relatives cremated at the funeral home where Li Wei worked?"

As a result, Lin Hao still shook his head.

"We have also investigated this."

"Chen Pingping's parents died five years ago. They were cremated at the Dongjiao Funeral Home, while Li Wei was working at Binyiguang in the southern suburbs."

"The same is true for Wu Jianguo's parents. They died twelve years ago. They were cremated at the Dongjiao Funeral Home, and they were buried in the Dongjiao public offering."

winter winter.

Chen Yan frowned as he looked at the information on the projection screen.

Chen Yan was a little confused by Lin Hao's investigation results.

If it was a vendetta, the murderer should have vendetta against all three.

After all, all three died in exactly the same way.

Moreover, Chen Pingping's son also died of spontaneous combustion.

In this way, the hatred between the other party and these three people is definitely the kind of deep hatred.

Otherwise, they wouldn't even kill the opponent's son.

However, what kind of hatred is it that makes the murderer hold such hatred?

How did the three get revenge with the murderer?

A nurse, a nursing home director, a funeral home security guard.

This is so...

There is absolutely no connection whatsoever.

In particular, Lin Hao's findings.

more confirmed this.

There was no communication between the three.

In other words, the possibility that the three of them conspired to do something basically does not exist.

So, what is the reason?

Everyone frowned.

There is no connection between the three, which means that it is impossible to find the murderer from the common contacts of the three.

Because, there is no such common contact at all.

boom!

At this moment, the door of the conference room opened.

It was Wang Xiurui, captain of the second division of the Dan City Detective Team!

"Team Chen, the investigation of shoes has made a major discovery!"

major discovery?

Zhang Yaoming next to Chen Yan looked at Wang Xiurui: "Xu Rui, what did you find?"

"Come on and talk"

Although Wang Xiurui's face was a little dark, and although he was deeply tired, the excited look in his eyes could not be concealed.

"Chen team, Zhang team, we visited all the shoe repair shops around Li Wei, Chen Pingping and Wu Jianguo's residence They all said that there was a mobile shoe repairer who appeared around them recently."

"Because the price is cheap and the craftsmanship is good, many people have repaired shoes."

"And when I visited Li Wei, Chen Pingping and Wu Jianguo's spouse, this was also confirmed."

"Is there any monitoring of this person?"

"Yes!" Wang Xiurui began to operate the computer: "We found this figure in the surveillance of Li Wei's house, Chen Pingping's house, and Wu Jianguo's vicinity."

Kacha.
