Chapter 172 Clues Converge

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

"Song Pengcheng's mother... just passed away four days ago, why did he return to Fengxian at this time?"

According to the folk custom of Dan City, when parents die, children should mourn in front of the coffin for the first seven days.

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

In theory, at this time, Song Pengcheng should be in Dan City to guard his mother's coffin, and should not return to Fengxian.

"Oh, I asked about this," Lin Hao nodded: "Song Pengcheng just came back from Dan City this morning, and just arrived at the hospital a few hours ago."

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

"Fengxian Hospital knows Song Pengcheng's situation, so they called to ask for his opinion."

"But Song Pengcheng said that the operation will not take long, and if the operation on this patient is not performed today, then all the previous preparations will be 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.

With a slight twitch of his nose, the smell that permeated the surroundings immediately appeared in Chen Yan's mind.

The strong smell of carbonization filled the entire shed.

On the ground, there was only half of the charred corpse.

The upper body had been completely carbonized, and only the lower body was still there.

However, the lower leg was already burned, leaving only half of the carbonized bone residue exposed.

In addition to the strong smell of coke, there was also a hint of sweetness.

The unique smell of charred protein was similar to the aroma of a well-cooked skewer.

It was the smell of roasted human flesh.

At this moment, the half corpse still had a certain temperature. When Chen Yan approached, he could feel a slight heat blowing on his face.

In addition, there were some other details.

First of all, most of the half corpse was blackened, but there were several points with very obvious burn marks.

It seemed that the burning of the entire corpse started from these points.

From the point to the surface, it spread.

At the same time, some fine metal powder could be observed on the corpse.

"Was the deceased holding an umbrella at the time?" Chen Yan used a special probe stick to gently touch the obvious burn marks on the body.

Lin Hao nodded: "The place where the deceased had the accident is right in front of the hospital. There is a surveillance video."

"The video shows that Song Pengcheng was indeed holding an umbrella, and..."

"And what?"

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

Also a new umbrella?

Zhang Yaoming's heart suddenly trembled.

Could this eucalyptus really be related to the umbrella?

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

The four people actually used new umbrellas when they spontaneously combusted.

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

After a moment, Chen Yan finished his observation.

"I want to see the surveillance video, and I want to personally ask some questions about the witnesses and security guards at the time."

Lin Hao nodded and made arrangements immediately.

Chen Yan walked out of the plastic shed with a solemn face and frowned.

Chen Yan found many details at the scene of this eucalyptus.

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

Moreover, Chen Yan had some guesses about why the dead body could spontaneously combust and why it spontaneously combusted on rainy days.

Even why the heavy rain could not extinguish the burning body of the dead body.

Also, why the four people were holding umbrellas, and they were new umbrellas, there was some speculation.

However, these speculations and inferences need to be corroborated.

Fengxian Hospital Security Room.

The monitor screen is playing the natural picture of Song Pengcheng.

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

Looking down from a bird's-eye view.

12:17.

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

"This is Dr. Song."

The security captain next to him immediately pointed out to Chen Yan and others which one was Song Pengcheng.

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

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

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

"Song Pengcheng had finished the operation and was about to drive back to Dan City, but something happened at this time."

As soon as Lin Hao finished speaking, Song Pengcheng in the video suddenly paused slightly, and then a fire spread.

The fire seemed to have arisen out of thin air and instantly engulfed Song Pengcheng.

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

In just two minutes, he collapsed to the ground.

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

However, the fire was still very big, and the fire extinguisher seemed to have no effect at all.

Until the other two security guards rushed out, three fire extinguishers worked at the same time, and finally extinguished the flames.

The video ends.

"Captain Chen, this is the whole process of the crime."

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

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

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

In Chen Yan's mind, pictures flashed one by one.

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

The same parts of the four videos were compared in Chen Yan's mind.

He was trying to find the common points between the four people.

Mainly some small details.

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

Li Wei held the umbrella with his right hand, and so did Chen Pingping.

However, Wu Jianguo and Song Pengcheng held the umbrella with their left hands.

This point... is not common.

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

There was no one around when Li Wei spontaneously combusted, but there were witnesses when the other three spontaneously combusted.

Everyone's expression was surprised, unbelievable, and fearful.

However, there was no gloating or cold-eyed watching as Chen Yan expected.

For spontaneous combustion, anyone who can see it will definitely have a great stimulation and change in their eyes and expressions.

And once there are people who watch coldly, then there must be a problem.

But...

No.

Although the expressions of the witnesses are different, they can all reflect drastic emotional changes.

After a while, Chen Yan's eyes left the monitoring screen.

The four people have something in common.

And more than one.

However, there was no new discovery.

"Captain Chen, how is it?" Zhang Yaoming's mind was confused now.

Four people!

That's four people.

Just now on the road, Qin Chuan called directly and asked about the specific situation.

So, Zhang Yaoming is very anxious now.

These are all things that happened in the territory he manages.

Not to mention that the eucalyptus can't be cracked, is his hat still there?

How can he give an explanation to the deceased and the deceased's family?

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

"Just like the three cases before."

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

"And, look at the leather shoes on his feet, they are also a pair of old shoes, but they have just been repaired, and the spikes on the left heel are brand new."

Zhang Yaoming nodded.

He just discovered this.

Chen Yan had just arranged Wang Xiurui and Lan Feng to investigate the umbrella and shoe repair, so after watching the video, Zhang Yaoming carefully looked at Song Pengcheng's umbrella and shoes.

"Lin Hao, call the security guards who put out the fire for Song Pengcheng when he caught fire. I'll ask them about the details of the time."

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

...

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

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

Wang Jie was the first security guard to find that Song Pengcheng was on fire. He rushed out of the hospital gate and put out the fire for Song Pengcheng with a fire extinguisher.

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

"Doctor Song...is from Dan City First Hospital supporting us. He has very good medical skills..."

"My...my dad's operation was performed by Doctor Song..."

"At that time, when Doctor Song went out, I sent him off for two steps. He said hello to me..."

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

Wang Jie's voice was a little stuttering at first, but later, it slowly became fluent.

"Can you tell me what it was like when you first saw Dr. Song on fire?"

Although Chen Yan watched the four videos of the four people spontaneously combusting, all the video angles were shot from top to bottom.

Moreover, the four people were holding umbrellas at the time, so Chen Yan did not see the expressions of the four people at the time.

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

All were blocked by the umbrella.

When the umbrella burned, the fire had already started and nothing could be seen.

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

She and Chen Pingping were walking side by side, and suddenly felt the scorching waves around her, so she turned her head to look at Chen Pingping.

At this time, Chen Pingping was already burning.

The same was true for the two eyewitnesses who saw Wu Jianguo on fire.

When they looked over, Wu Jianguo had already turned into a ball of fire.

After a few minutes of intense burning, he became a pile of ashes.

Hearing Chen Yan's question, Wang Jie's eyes shrank slightly uncontrollably: "At that time, I watched Dr. Song leave the hospital gate."

"As a result, when he walked down the steps and went to the parking lot, it seemed like a fireball fell from Dr. Song's head."

"Then... with a bang, Dr. Song burned up in the white light."

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

"But... it was still too late..."

"The fire on Dr. Song was particularly intense. Before I got to him, I felt a particularly hot wave rushing over."

"At that time, I opened the fire extinguisher and sprayed it on Dr. Song..."

"But it seemed to have no effect at all..."

"If Zhang Laosan and others hadn't come to help behind, the fire would not have been extinguished at all."

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

From discovering that Song Pengcheng was on fire to extinguishing the fire, as well as some details in between, they were all described quite well.

Especially the initial stage of Song Pengcheng's body on fire, which made Chen Yan's eyes light up.

This was the first time he learned about the four people on fire and what happened at the first moment.

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

"Yes," Wang Jie nodded, waving his arms in a circle: "When the fire burned, the rain seemed to burn with it."

"This is the first time I've seen it. The more the rain falls, the bigger the fire becomes."

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

As if he remembered the situation at the scene again, Wang Jie spoke quickly and trembled a little.

"Wang Jie, did you hear Dr. 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 Dr. Song shouted, I should be able to hear him."

Chen Yan nodded.

There were no witnesses at the scene of Li Wei's spontaneous combustion, and it was impossible to restore the sound conditions at that time.

However, when Chen Pingping and Wu Jianguo spontaneously combusted, witnesses reported that they did not hear any shouting.

this……

It's rather strange.

Even if the burning was very fast, it was impossible to destroy the vocal cords in an instant and make the three of them unable to make a sound.

Also, what is a person’s first reaction when his body is on fire?

As long as he is not dead, the first reaction is to put out the fire.

So, definitely falling to the ground, rolling around, trying to put out the flames on him.

However, the four deceased people did not react at all when the fire broke out.

It was like fire was already burning inside their bodies.

In an instant, their vitality was destroyed and their lives were taken away.

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

Song Pengcheng's death scene showed that the flames came from the outside inward.

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

Next, Chen Yan listened to the statements of two other security guards and two people who walked out of the door with Song Pengcheng and witnessed the entire process.

Basically consistent with Wang Jie’s confession.

However, they had not paid much attention to Song Pengcheng, so their description of the early stages of the fire was not as detailed as Wang Jie's.

In fact, the two people traveling with Song Pengcheng did not see how Song Pengcheng started the fire at all.

When they found it, the umbrella had been burned out.

Three hours later.

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

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

It was already evening when we returned to Dan City Detective Team.

It's drizzling in Feng County, but the weather in Dan City is just right.

At dusk, the sunlight spreads through the windows, giving the entire conference room a golden layer.

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

…

The second situation analysis meeting.

Katcha.

There are three photos on the screen.

"Team Chen, we have completed the tracking of the three deceased persons using umbrellas."

Lan Feng is reporting on the investigation results.

"The umbrella Li Wei uses is a Sunshine brand umbrella, and the manufacturer is in Dan City."

"Sunshine brand umbrellas have the largest market share in Dan City. They are sold in basically every store."

"Based on the clues in the video, we visited the sun umbrella manufacturer."

Card rub.

Screen-cast photo switch: "This is the same batch of umbrellas used by Li Wei. A total of 50,000 were produced."

"It started selling last summer."

"Until now, it is still circulating in the market."

"So, it's difficult to trace this direction..."

Chen Yan and others nodded.

Sun Umbrella, Chen Yan knows this brand.

They are even sold in cities.

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

The quality is good, the price is cheap, and the style is good.

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 used a similar new umbrella before."

Zhang Yaoming frowned: "In other words, Li Wei got this umbrella while working in the funeral parlor?"

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

"But, he is different from other security guards."

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

"Instead of sleeping in a Datong shop like other security guards."

"According to the person in charge of the funeral home, Li Wei used to be a cremator operator, which is the best paying position in the funeral home."

"It's just that five years ago, he took the initiative to apply to leave and work as a security guard, but some benefits must have been retained."

Chen Yan nodded. This Li Wei is a formal employee of the funeral home, so there is a natural difference between him and the hired security guard: "Whether the funeral home said it, why does this Li Wei work as a security guard?"

Lan Feng looked at Chen Yan and nodded: "I probably asked about it 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 for drinking while working, which almost caused a work accident."

ACCIDENT?

"What accident?"

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

Living person?

Great refining of living people?

Zhang Yaoming frowned: "What is the specific situation?"

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

"If Li Wei really made such a mistake at work, how could he continue to work in the funeral home?"

"So, I checked the information from that year."

It turned out that what happened that year was actually a misunderstanding.

Ten years ago, a dead person was sent to the funeral home.

The whistleblower said that the dead person was not dead yet, but was pushed into the crematorium by Li Wei.

I called the leader immediately.

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

In addition, the death certificate and other procedures of the dead person were all complete at that time.

There is no possibility of fake death at all.

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

"Then, what does this have to do with Li Wei working as a security guard?"

Chen Yan frowned slightly.

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

"Although the incident has passed and has been determined, the whistleblower at that time brought it up when he got drunk."

"Every time I had to go to Li Wei to argue, and then, after a few years, Li Wei simply quit and became a security guard at the door."

"Okay, let's continue with the investigation of the umbrella just now."

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

"Yes, Captain Zhang!"

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

"But these people don't know the specific situation."

"It was the security guard on duty with Li Wei who told a situation."

"Everyone, look..."

Lan Feng started playing a video.

"This is the surveillance video of the funeral home's duty room, which is the video that captured the scene of Li Wei's self-ignition."

"On the 18th, that is, the day before Li Wei's accident, at 3:28 pm."

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

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

The video paused and zoomed in.

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

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 City, and the picture in the video was very clear.

Sure enough, this direction of investigation is useful.

Zhang Yaoming's expression was excited, and his eyes were shining as he looked at the video.

"Captain Chen, next, as long as we find out who gave Li Wei an 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 was arranging work, he mainly considered the probability of coincidence.

Three people, no, now four people, using new umbrellas at the same time when spontaneously combusted, what is the probability?

According to common sense, it is basically impossible.

Therefore, Chen Yan decided to pursue this direction.

In the afternoon, at the scene where Song Pengcheng died, Chen Yan further confirmed that his direction of investigation was correct.

Because, Chen Yan basically had a guess about the spontaneous combustion of human body.

Now, just waiting for the results of Song Pengcheng's autopsy to come out, we can prove Chen Yan's idea.

And the umbrella is the most critical link.

However, Chen Yan is not optimistic about finding the murderer by relying on this alone.

Since the other party can plan such a bizarre and strange spontaneous combustion death, how can he lock the other party just by an umbrella?

Sure enough.

Lan Feng looked at Zhang Yaoming and operated the projection: "Captain Zhang, we have started investigating this aspect."

"The courier called Li Wei that day, and we have found him."

"The other party just took the order normally and delivered oil and umbrellas to Li Wei. Other situations, nothing is clear."

Uh...

In this case...

Is the clue broken?

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

"I asked 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 Wei asked him to wait on the roadside."

Chen Yan glanced at Lan Feng and thought to himself that it was indeed the case.

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

However, as Chen Yan believes, if you don't want others to know, you must not do it yourself.

As long as you do it, you will definitely leave clues.

"Captain Lan Feng," Chen Yan looked at Lan Feng: "What progress has been made on the umbrellas of Chen Pingping and Wu Jianguo?"

"Yes!"

Lan Feng's answer was decisive, which shocked everyone.

"The umbrella Chen Pingping used is a Paradise umbrella."

"This type of umbrella is sold in small quantities in Dan City. We checked and found that only five stores are selling it."

"However, we checked the recent videos of the relevant stores and found no record of Chen Pingping buying it."

"In addition, we also compared Chen Pingping's online shopping records and found no record of her buying it online."

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

"Because Chen Pingping had many umbrellas at home, Chen Pingping's husband asked about it at the time, but Chen Pingping did not say how it came from."

"I just said that it doesn't cost anything anyway, so don't worry about it."

"As for Wu Jianguo's umbrella, it is the umbrella provided by the nursing home."

"We visited Wu Jianguo's office director, and 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, one month ago...

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

Lan Feng shook his head: "We have checked and it is indeed not there."

The clues about the umbrella have basically been collected.

It has to be said that Lan Feng's administrative ability is indeed good.

In less than a day, the usage of umbrellas by the three deceased people was basically the same.

"Captain Chen, look, now..."

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

"Captain Lan Feng, thank you for your hard work." Chen Yan stood up and looked at Lan Feng's group.

"The clues about Umbrella are relatively detailed, and they give us a clear direction for what to do next."

Chen Yan paused, stood up and walked to the whiteboard.

Pick up a pen and write the word "umbrella" on the whiteboard.

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

Katsa, projection changes.

It's a photo of Song Pengcheng.

"The deceased, Song Pengcheng, died of mysterious spontaneous combustion at the entrance of Feng County Hospital."

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

"Moreover, after preliminary investigation, it was found that the deceased Song Pengcheng was the son of the deceased No. 2 Chen Pingping."

"From the 19th to now, the 26th, and in between, the 22nd and 24th, there has been one spontaneous combustion incident every day!"

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

"Preliminarily, we can conclude that this was a well-planned, frenzied and deliberate killing."

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

"It can be inferred from this that the murderer and the other two people may also have a grudge relationship."

"So, at present, it seems that our investigation direction is not too far off."

"The clues for the investigation of umbrellas and shoes have now begun to take shape. Combined with the death scene of Song Pengcheng, I have already made some speculations about the principles of these four spontaneous personal combustions."

"Now, we just have to wait for Song Pengcheng's autopsy report to come out, and then we can provide evidence."

"So, don't be discouraged, but have confidence."

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

"Next, I will arrange the next step."

"First, Lan Feng's team traces where the cooking oil given to Li Wei was sold."

Katcha.

The projection switch is exactly what Lan Feng showed you just now, the scene of Li Wei carrying cooking oil and umbrella under surveillance.

"The umbrella in Li Wei's hand, looking at it now, is most likely to have been passively manipulated, but it is difficult to trace the source."

"But please pay attention to the cooking oil in Li Wei's hand."

"Basan cooking oil!"

"I saw a billboard for this brand of cooking oil on the car at noon."

"A specialty of Dan City, and it has just been repackaged."

"This kind of cooking 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 cooking oil is still in Li Wei's dormitory, we will try our best to trace it."

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

"Ten years after the incident happened, the other party still refuses to forgive me. There may be some inside information here."

"Find out the relationship between the two, and if necessary, summon them directly for questioning."

"Yes!" Lan Feng stood up and responded.

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

"The grudge between Yun Guifang and Chen Pingping has been going on for a long time. It includes both the old grudge from back then and the new grudge in recent years that Chen Pingping's son squeezed out Yun Guifang's son to join the First Hospital."

"At present, Song Pengcheng has been killed again, and Yun Guifang's family is currently the focus of suspicion."

Zhang Yaoming nodded.

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

He knew the specific situation very well.

"Third, it's the situation on Wu Jianguo's side."

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

"According to the investigation results of Captain Lan Feng, the umbrellas in Wu Jianguo's office were not used from the time they were distributed to the day Wu Jianguo used them."

"check!"

"Lan Feng, find out who are the people who have access to Wu Jianguo's office, and who may have access to that umbrella."

“Focus on the period after umbrellas are issued.”

Because, Chen Yan judged, the distribution of umbrellas was random, and the possibility of the other party doing tricks was relatively small.

However, when things are distributed to Wu Jianguo, most people will not touch them.

After all, Wu Jianguo is the director of a nursing home. Who among his subordinates has nothing to do with touching the boss's things?

"Fourth, Song Pengcheng should be included in the investigation scope simultaneously."

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

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

"Including the residence of their children in Dan City, especially the umbrellas and shoes they used, carefully inspected them."

…

It was 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 taking out his phone and looking at Sister Xiaoyu's WeChat profile picture, Chen Yan felt happy.

"Baby Yunyun..."

"Guess where I am?"

"Either on the bed, or under the bed... Hehe!"

After sending a grimacing message, Shen Yunyi always responded to Chen Yan's WeChat message instantly.

Chen Yan found this very magical.

Doesn’t Sister Yu even go to work?

Can I see my WeChat every time?

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

When Chen Yan is on a business trip, Sister Xiaoyu will set Chen Yan’s WeChat notification tone as a special ring tone.

Whether you are in a meeting or having guests, you will never set your phone to vibrate.

Everything must make way for Chen Yan.

Chen Yan's priority in Xiaoyujie's heart is always the first.

Looking at the message from Sister Xiaoyu on the screen, Chen Yan's mouth twitched slightly.

Isn't it?

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

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

At this moment, Little Sister Yu is lying on the bed.

Under the silk pajamas, there is a well-proportioned figure.

Her long black hair was scattered on the pillow, and she looked at the screen of her phone with a silly smile.

Less domineering as a queen, more silly and cute.

Gan!

This damn charm...

"Fool, I don't want to accompany you to climb mountains, my back will hurt from exhaustion..."

After the young couple talked sweetly, Chen Yan made a video call. Looking at Sister Yu's outfit, he almost ran back directly.

…

Early the next morning.

The weather in Dan City is a bit gloomy.

It looks like it's going to rain again.

However, after arriving in 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."

Katcha.

Screencast switching.

It is a picture of three trajectories.

"We contacted the communications department and retrieved the tracks of the three people's mobile phones."

Chen Yan nodded.

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

However, it is not precise.

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

In this way, you can mark each point on the map.

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

However, it is a good way to eliminate it.

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

"We used this method to rule it out first."

Katcha.

The photos on the screen are switched again.

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

What Lin Hao did was actually compare all the base stations that the three people's mobile phones were linked to.

If there is no overlap between the mobile phone and the base station, then the spatial possibility of their overlap is basically gone.

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

"This is concrete information."

On the screen, the specific times when the three people visited these two places were projected.

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

"We checked the surveillance at the time and found that Chen Pingping went to square dance in the square."

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

"The other two were passing by the square and Victory Road, and there was no sign of staying for a long time."

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

"How is their medical treatment?"

Chen Yan actually didn't have particularly high hopes in this regard.

After all, the career and living environment of the three people are very different.

It's normal if you don't know them.

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

"Chen Pingping has had it before, and it was all at the No. 1 Hospital."

"Wu Jianguo had a minor surgery in the past two years, but it was performed in Shen City. There is no medical record in Dan City."

"However, Wu Jianguo has a physical examination record at the First Hospital, which is ten years old. It is in the physical examination department."

Chen Yan frowned: "In other words, they have never crossed paths in terms of medical history?"

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

"How is the investigation of other relationships going? For example, do Li Wei and Chen Pingping have any relatives in Wu Jianguo's nursing home?"

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

In the end, Lin Hao still shook his head.

"We have also investigated this."

"Chen Pingping's parents died five years ago and were cremated at the Dongjiao Funeral Home, while Li Wei worked at Nanjiao Binyiguang."

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

Winter winter winter.

Chen Yan looked at the information on the screen and frowned.

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

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

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

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

From this point of view, the hatred between the other party and these three people is definitely a deep hatred.

Otherwise, he wouldn't even kill the other party's son.

But what is the grudge that makes the murderer hold such a grudge?

How did the three of them become enemies with the murderer?

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

What the hell...

There is no correlation at all.

Especially, Lin Hao’s investigation results.

This is further confirmed.

There is no correspondence between the three of them.

In other words, the possibility that the three of them conspired to do something is basically non-existent.

So, what is the reason?

Everyone also frowned.

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

Because there is no such common contact at all.

boom!

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

It is Wang Xiurui, the captain of the second detachment of the Dan City Detective Team!

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

major discovery?

Zhang Yaoming beside Chen Yan looked at Wang Xiurui: "Xiurui, what did you find?"

"Come and tell me"

Although Wang Xiurui's face was a little gloomy and he showed deep exhaustion, the excitement in his eyes could not be concealed.

"Team Chen, Team Zhang, we visited all the shoe repair shops around the residences of Li Wei, Chen Pingping and Wu Jianguo."

"They all said that a mobile shoe repairman appeared near them recently."

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

"This was also confirmed when we visited the spouses of Li Wei, Chen Pingping and Wu Jianguo."

"Is there any surveillance on this person?"

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

Katcha.
