In view of the corpse in the room, Gu Chen did not dare to neglect, so he quickly contacted the Wangchao Town Police Station and asked Zhang Wenxia to transfer all the police officers he could mobilize to the scene of the incident.
On his side, after controlling Zhou Zheng, he continued to the door.
Seeing that the door lock was intact but had the simplest lock cylinder, Gu Chen immediately felt that anyone who was good at picking locks could basically pry it open.
Therefore, Zhou Zheng's door is almost useless to this kind of people.
But after all, Zhou Zheng himself said that he just saw Yuan Jialiang passing by his residence early in the morning and then walking towards the mountain.
Obviously, according to Zhou Zheng's statement, the two of them had not met this morning.
But even so, Yuan Jialiang died in Zhou Zheng's room, which made Gu Chen feel that the murderer seemed particularly arrogant.
He even knew that Zhou Zheng was not at home.
Turning to look at the shivering Zhou Zheng behind him, Gu Chen asked again: "What time was it when you saw this man going up the mountain today?"
"Probably...around 9 o'clock?" Zhou Zheng said.
"Then what time did you leave the room and go down the mountain?" Gu Chen asked again.
"Yes... it must have been around 9:30." Zhou Zheng also said in retrospect.
"9:30?" Lu Weiwei muttered, and couldn't help but say: "That means, after 9:30, you went down the mountain and didn't meet anyone again? Until you met us when you came back?"
"Yes." Zhou Zheng was also very frightened at this moment, and he quickly nodded and admitted: "I came down the mountain around 9:30, and went to the vegetable fields at the foot of the mountain."
"Anyway, I didn't meet anyone else along the way. I only met you when I came back."
"But, I really don't know why this person is in my residence? My room? I obviously have a locked door."
"Have the windows around you not been opened?" Yuan Shasha also asked.
Zhou Zheng shook his head: "Everything is closed and locked from the inside."
"And some ventilation windows, although open, are fixed with steel bars to prevent theft, so no one can get in."
According to Zhou Zheng, Lu Weiwei also confirmed it again, then returned to Gu Chen and confirmed:
"He is right. The windows in the room do have steel anti-theft guardrails."
"I said, I really don't know how this person died in my room?" Zhou Zheng felt wronged, but after thinking about it, he quickly said:
"Maybe, maybe this person came here with the murderer after I left, but they saw the door was locked, so they picked the lock themselves, went into the house to rest, and then..."
Looking up at Gu Chen, Zhou Zheng also guessed and said: "Then, he had a conflict with the murderer and was killed by the murderer in the room, and then the murderer escaped."
"But this person was obviously poisoned to death." Lu Weiwei quickly replied.
"But, it seems that none of the tableware here has been touched." Zhou Zheng also reminded.
Yuan Shasha also nodded silently: "Yes, I have checked the kitchen. The tableware is arranged neatly and there are no signs of being tampered with."
"Of course, it is not ruled out that the murderer washed the tableware after poisoning the deceased, or took the poisoned tableware away with him."
"Zhou Zheng." As soon as Yuan Shasha finished speaking, Gu Chen reminded her, "Come to the kitchen with me."
"Okay." Zhou Zheng did not dare to refute now. He could only stand up obediently and quickly followed behind Gu Chen.
Everyone came to the kitchen together. Gu Chen gave up his position and continued to remind: "Check your kitchen, focus on what items are missing?"
"Wait a moment." After hearing what Gu Chen said, Zhou Zheng squinted his eyes and began to investigate.
However, after a moment, Zhou Zheng shook his head: "Comrade police, all the tableware are here. I don't have a few tableware in the kitchen, so that's all."
"Collect all these things." Gu Chen also reminded.
Fortunately, Yuan Shasha carried some transparent evidence collection bags in her carry-on bag.
So all the tableware and cups were wrapped with numbers in transparent evidence collection bags, and photos were taken for evidence collection.
Gu Chen reminded Zhou Zhengdao: "We will take these things to the Municipal Bureau's Technical Section later to test the residual substances."
"Okay." As soon as Gu Chen finished speaking, Zhou Zheng nodded vigorously and agreed readily.
Zhou Zheng will spare no effort to cooperate with the police wherever he can.
I feel that as long as I can clear myself of suspicion, I must go all out.
Since it would take time to wait for support, after Officer Wang sent Zhang Wenxia the specific location, he and Yuan Shasha stayed here to protect the scene.
Gu Chen and Lu Weiwei were sent to go to the wild grave on the mountain with Zhou Zheng to check the situation.
The three of them walked for about half an hour. Zhou Zheng suddenly stopped, pointed to a place in front of him and said, "The wild grave is right there."
Gu Chen and Lu Weiwei took a step forward and saw a raised hill in a clearing in the mountains.
At first glance, it looks like just a raised hill, but the weeds around it seem to have been cleared away.
It looks like the prototype of a tomb.
"How can you tell that this is a wild grave?" Gu Chen asked Zhou Zheng.
Zhou Zheng waved his hand: "I didn't know that at first, but I heard it from that person later. He said that the purpose of going up the mountain was also to worship."
"But I'm very puzzled. Since he came all the way here and came to worship for several days in a row, it feels quite strange."
"Besides, he has so many days, why doesn't he erect a stone monument or something for this wild grave?"
Also listening to Zhou Zheng's words, Gu Chen and Lu Weiwei slowly came to the so-called wild grave.
At this time, the weeds around the "wild grave" were completely cleared. Not only that, even the weeds on the wild grave were also cleared and filled with some new soil.
Gu Chen was confused and shook his head: "It's so weird. What does this Yuan Jialiang mean? He has been to Jiangnan City before?"
This chapter is not over yet, please click on the next page to continue reading! "How did he know that there was a wild grave on this mountain? Who is buried in the wild grave?"
"I don't know." Zhou Zheng walked up to Gu Chen and explained:
"I have lived in the mountains for so long, and I have never heard anyone mention it, that is, this man named Yuan Jialiang. After he came, I realized that it turned out to be a wild grave. I had no idea about it before.
Notice."
"Wait for colleagues from Wangchao Town Police Station to come over later to provide support and confirm the situation here," Gu Chen said.
"Yes." Lu Weiwei nodded silently, then looked around and said curiously:
"You said that this Yuan Jialiang comes here every day just to walk around the wild graves on the mountain a few times? It can't be that simple, right?"
"And he leaves early and comes back late every day, for 10 consecutive days. Is he crazy?"
"How do I know this?" Zhou Zheng shook his head.
But Lu Weiwei said angrily: "You said that you are a hermit and have stayed in the mountains for such a long time. Why don't you get to know more about people from other provinces who suddenly come to visit you?"
"Comrade police." Seeing that Lu Weiwei went around to the end and still turned the suspicion on herself, Zhou Zheng was also speechless and said:
"I came here just to be quiet. I don't like places that are too busy, really."
"What if someone comes up the mountain? Anyway, some people will come up the mountain one after another, but not many."
"I don't want to get involved in these people's affairs, but I don't really like these people disturbing me. I just want to be quiet."
"Okay." Seeing that Zhou Zheng was also very depressed at the moment, Gu Chen did not embarrass him for the time being and reminded him:
"We will send all the tableware in your kitchen to the Technical Department of the Municipal Bureau for testing. I hope no residual toxic substances are detected, otherwise you'd better give me a reasonable explanation."
"Yes, yes, yes." It felt like he had no choice but to accept his fate when it came to this kind of thing, so Zhou Zheng was now in a broken state.
After several people checked around the wild tomb, they returned to the ancient temple.
At this moment, Zhang Wenxia had arrived at the scene with two police officers and several enthusiastic people.
I happened to meet Gu Chen who was coming down from the mountain.
Zhang Wenxia also hurried forward to say hello: "Gu Chen, I have brought the people you want. In addition, I was afraid that there was not enough manpower, so I called a few enthusiastic people over."
"Have you brought anything?" Gu Chen asked.
"Is this okay? I borrowed the stretcher from the health center." Zhang Wenxia gave up her position, and an enthusiastic member of the public immediately placed the folding stretcher in front of her.
"Okay." Lu Weiwei nodded silently.
Zhang Wenxia added: "I have also brought the cloth for wrapping the body. The transportation here is inconvenient, so we can only transport the body out on a stretcher and then take the railway."
Before Zhang Wenxia finished speaking, Officer Wang had already walked out of the house.
When he saw Zhang Wenxia, Officer Wang quickly asked her: "Zhang Wenxia, what's going on with the wild graves on the mountain? Have corpses been buried here?"
"Well……"
Hearing Officer Wang's words, Zhang Wenxia was stunned for a moment and shook her head: "This... I'm not very clear."
"Maybe." As soon as Zhang Wenxia finished speaking, an enthusiastic crowd behind her said, "I heard from the older generation that an unknown corpse was once buried on the mountain here."
"Because it has been a long time, few people know about it, and it is not clear who the body is exactly. Therefore, no one has erected an inscription or anything like that."
"Then do you know anything else about this wild grave?" Seeing that the enthusiastic crowd seemed to understand, Gu Chen quickly asked again.
The enthusiastic crowd shook their heads: "I don't know about the rest. I heard it from my grandparents. As for where the wild grave is? In fact, I don't know. After all, the wild grave has been there for many years."
"I guess the grass on the graves has already covered the wild graves. My friends and I have visited here several times and also been to the top of the mountain, but we have never found the location of the wild graves."
"Yes." As soon as the man here finished speaking, another fat and enthusiastic member of the public quickly agreed:
"I have been to this mountain several times, but I have never seen any wild graves? I just heard people talk about them."
"That's strange." After hearing what the two said, Gu Chen frowned slightly and said in confusion:
"You locals don't know much about the situation of this wild grave, and you can't even find the specific location of this wild grave."
"But Yuan Jialiang, a foreigner, can find it accurately and help clear the weeds of this wild grave. What is he doing?"
"Or maybe the people buried in this wild grave are his relatives?"
"This... is very possible." After hearing what Gu Chen said, Officer Wang also felt that there was something strange about the tomb.
Thinking of Gu Chen and Lu Weiwei, who had just come down from the mountain, Officer Wang quickly asked Gu Chen again:
"By the way, Gu Chen, you and Lu Weiwei came down from there just now. What's going on over there?"
"All the weeds around the wild grave were cleared away. Maybe it was Yuan Jialiang who did it?" Gu Chen said.
Officer Wang shook his right index finger: "In other words, Yuan Jialiang came to this mountain these days just to visit this wild grave?"
"But how can he accurately know the location of the wild grave?"
"Perhaps someone told him." Gu Chen also speculated.
Everyone stood at the door and communicated for a while, then came to the room together, wrapped Yuan Jialiang's body in cloth and tied it tightly, and then put the body on a stretcher.
After that, two police officers sealed off the scene, and Gu Chen also completed all the photography and evidence collection.
Since he needed to find out the specific situation as soon as possible, especially the origin of Yefen, Gu Chen walked to Zhang Wenxia and whispered:
"Senior Sister Zhang, can this wild grave be excavated and find out who is inside?"
"this……"
Hearing what Gu Chen said, Zhang Wenxia suddenly trembled: "This...isn't this not good? After all, it is disrespectful to the deceased."
This chapter is not over yet, please click on the next page to continue reading the exciting content! "Although, I don't know the specific identity of this person, but I always feel..."
"However, if this wild grave is not excavated, it will be impossible to confirm the specific identities of the people buried in the wild grave."
"It is impossible to confirm what is the relationship between this person and Yuan Jialiang?"
Before Zhang Wenxia could finish speaking, Gu Chen also expressed what he was thinking.
Zhang Wenxia nodded silently: "I know, this is an important clue for your criminal investigation team."
"Otherwise, I'll contact the village cadres of the nearby villages first. If no one claims them, then you can lead people to dig out the wild graves and take the corpses back for testing."
"After all, it's unclaimed and it complies with the regulations. What do you think?"
"Then I'll have to help Senior Sister Zhang." Seeing that Zhang Wenxia also gave the best solution, Gu Chen was naturally relieved.
Subsequently, two police officers stayed at the crime scene to handle follow-up matters.
Gu Chen, Lu Weiwei, Officer Wang and Yuan Shasha, together with Zhang Wenxia, carried Yuan Jialiang's body down the mountain with the help of several enthusiastic people.
Also following Gu Chen and others down the mountain is Zhou Zheng, who will also return to the Wangchao Town Police Station with them for further investigation.
…
…
When I returned to Wangchao Town Police Station, it was already 3 p.m.
So everyone had a simple meal under Zhang Wenxia's arrangement.
Since the Wangchao Town Police Station is small, the number of police officers is also very small.
A few years ago, when the population was small, it was set up as a police station.
In recent years, due to good agricultural development, green enterprises have begun to take root in Wangchao Town.
Only then did Wangchao Town turn from population outflow to population inflow.
But even so, there are only five police officers in the entire Wangchao Town Police Station.
In the future, the police force will be gradually increased based on the population size.
However, after Gu Chen called for support, around 3:10 p.m., Gao Chuanfeng's team from the Municipal Bureau's Technical Section also drove to the door of the Wangchao Town Police Station.
"Gu Chen." Gao Chuanfeng got off the car and walked towards Gu Chen. The two forensic assistants beside him also brought relevant supporting equipment.
Including body bags and other supplies.
Gu Chen put down the empty lunch box he had just finished eating, pointed to the stretcher on the ground and said: "The person is here. It is initially presumed that he died of poisoning. You can take it back for testing first."
"In addition, we also have some packaged tableware here. You can also take it back for testing. If you have the results, please notify us immediately."
"Eating so late?" After listening to Gu Chen's introduction, Gao Chuanfeng walked to Yuan Jialiang's body, opened the shroud, and started on-site inspection.
Several forensic assistants also gathered around.
On the other side, Zhang Wenxia is still actively contacting nearby village cadres to repeatedly confirm the identity of the wild grave on the mountain.
As for Zhou Zheng, because the place of death of Yuan Jialiang was Zhou Zheng's bedroom, Zhou Zheng was temporarily detained here for further interrogation.
After completing the preliminary inspection, Gao Chuanfeng asked two assistants to put the body into a body bag, hand over other items together, and take them into the car.
Arriving in front of Gu Chen, Gao Chuanfeng said again: "Gu Chen, I heard that Bureau Qin is still angry about the matter in Wangxian Valley. The whereabouts of He Xu and Zhang Fan's criminal gang are unknown, which makes Bureau Qin very confused.
fire."
"After all, a lot of police were sent to search the mountain, but one hostage was rescued, and the others disappeared, just like they disappeared from the world."
"So these days, Bureau Qin is also holding meetings every day, and has been urging to find the whereabouts of He Xu and Zhang Fan."
After a pause, Gao Chuanfeng said again: "So, you have to speed up the case processing. Bureau Qin still has very high hopes for you."
"If there is a breakthrough on your side, then our case will be fully revitalized. Therefore, Bureau Qin has also issued an order for all our departments to actively cooperate with your Furong Branch Criminal Investigation Team."
"I know." After hearing what Gao Chuanfeng said, Gu Chen was not surprised at all.
After all, Zhao Guozhi received the military order in front of Qin Gang.
Now the pressure is naturally on me.
Due to the special identity of He Xu and Zhang Fan, as well as the important evidence collected from the den destroyed last time in Shanlan Town, Qin Gang was shocked.
Therefore, Qin Gang's focus during this period will naturally be on this end.
But the strange thing is that Gao Chuanfeng said that Qin Gang attached great importance to the case, but he did not hear any urging from Zhao Guozhi.
Of course, Gu Chen also knew very well that Zhao Guozhi took all the firepower, so he did not rush himself.
The purpose is to prevent yourself from being overly stressed and thus affecting the efficiency of case handling.
Zhao Guozhi has always been like this and has full trust in himself, so Gu Chen feels that his own investigation work needs to be further accelerated.
Patting Gao Chuanfeng on the shoulder, Gu Chen also understood and said: "I understand. I have also issued a military order here. The case must be solved as soon as possible. I will take care of myself."
"That's good." Seeing that Gu Chen was in good condition, Gao Chuanfeng also warned: "What you want, I will test it for you immediately when I get back. If there are results, I will notify you as soon as possible."
"Okay, I'll trouble you then." Gu Chen said.
After the two briefly exchanged a few words, Gao Chuanfeng got into the car and drove away from the Wangchao Town Police Station.
At this moment, Zhang Wenxia happened to be walking over from the office area. When she saw the city bureau's vehicles leaving, she curiously asked Gu Chen: "They left?"
"Yeah." Gu Chen nodded silently.
"Oh, I didn't even ask them to have a drink, why did they leave?" Zhang Wenxia looked a little disappointed without seeing her colleagues from the Municipal Bureau.
But Officer Wang quickly asked Zhang Wenxia: "By the way, Zhang Wenxia, how is your contact over there?"
"Hello, I have contacted the village cadres in the surrounding villages and asked them to go to the village to inquire about the situation."
"Based on the current feedback, it seems that we don't know the specific identity of that wild grave."
"But in one village, the village cadre told me that when he went down to inquire about the situation, an old lady said that she seemed to know about the wild graves."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Real or false?" After hearing what Zhang Wenxia said, Lu Weiwei on the side was also curious and asked hurriedly: "Then... then now..."
"The village cadre has already driven the old lady over here. She will probably be here soon."
As soon as Zhang Wenxia finished speaking, she heard the sound of a car parked at the door of the police station.
Zhang Wenxia slapped her thigh, pointed in the direction of the door and said, "Hey, maybe it's them."
"Officer Zhang." A middle-aged man walked into the office area with a gray-haired old lady.
Seeing that everyone was there, and there were some unfamiliar faces, the middle-aged man walked directly to Zhang Wenxia and said, "I have brought the person. Please ask her what the specific situation is."
"Old lady?" She also saw the white-haired old lady walking behind the middle-aged man. She was the old lady who gave her cucumbers to eat. Lu Weiwei couldn't help but was stunned: "So it's you?"
"Eh? Little girl?" The old lady glanced at Gu Chen beside Lu Weiwei and said, "Young man, are you there too?"
"Yes, old lady, we meet again." Seeing this energetic old lady, Gu Chen responded with a polite smile.
Officer Wang was very curious and asked Gu Chen: "Do you know each other?"
"She is the old lady who gave us cucumbers to eat. Didn't you pass her by when you and Xiao Yuan were walking back?" Lu Weiwei also reminded her quickly.
On the other side, Yuan Shasha also suddenly realized: "Yes, we have seen it before."
"Old lady, please sit down." Seeing that this old lady was the provider of important clues, Gu Chen quickly helped the old lady sit on a seat, and then asked her:
"Old lady, you know there is a wild grave on that mountain, right?"
"Yes." The old lady nodded silently and said slowly: "That wild grave should have existed for about 15 years."
"Existed for 15 years? Such a long time?" Yuan Shasha couldn't help but be stunned when the old lady said this.
The old lady nodded silently: "Yes, that wild grave is very strange, but few people should know about it now."
"If our village chief hadn't come to me to inquire about this matter, I would have almost forgotten about it."
Seeing that the old lady really knew something, everyone immediately gathered around her.
"Old lady, please drink a glass of water." Zhang Wenxia politely handed a cup of freshly brewed tea to the old lady's rough hands.
"Thank you." The old lady nodded silently, took a small sip, and then said:
"So, what do you want to know from my old lady?"
"We want to know who is buried in that wild grave?" Gu Chen said.
"A foreigner, right?" The old lady looked up and recalled, and couldn't help but said, "I remember that there should be a foreigner buried in that wild grave."
"Moreover, that person seemed to have died a tragic death. It is difficult to confirm his identity. Some people said that he was a beggar. Anyway, there are different opinions and we can't figure it out."
"A beggar?" Lu Weiwei was stunned when she heard the old lady's words, and quickly asked: "How could he be a beggar?"
"Oh, that's what it's called anyway, right?" The old lady was drinking tea and thinking about it: "He's the kind of person who asks for money on the street. He walks to the door of your store with an erhu in his hand and pulls a few coins.
Get off. Then I’ll ask you for money.”
"If you don't give, he will keep pulling and pulling. If some businessmen are afraid of affecting the mood of the customers in the store, they will give a little. This is probably the case."
"So that's it?" After hearing what the old lady said, Yuan Shasha also understood a little bit, so she asked the old lady again:
"So old lady, this person is a foreigner, right?"
"Yes, it must be a foreign accent. I've seen it before," the old lady said.
"Later? Later I heard that this man huddled up in a warehouse to sleep at night, but that warehouse suddenly caught fire. The poor man was swallowed up by the fire and burned to charcoal alive."
After saying this, the old lady also looked distressed and couldn't help but frown.
At this time, Zhang Wenxia also nodded silently and echoed: "Fifteen years ago, a fire did occur in Wangchao Town, but I was not here at the time and I don't know the specific situation here."
"I understand." As soon as Zhang Wenxia finished speaking, the old lady continued:
"I remember that what was burning was a sponge factory. Oh, the sponges were all flammable. Once it burned, there was no way to put it out."
"Anyway, I felt that that night, there was thick smoke billowing everywhere around the sponge factory. Many people participated in putting out the fire, but they could not put it out."
"After the owner of the sponge factory counted all the personnel and made sure that everyone was safe, he felt relieved."
"If the sponge feels burned, just burn it. At least the person will be fine."
With a faint sigh, the old lady continued to recall: "Later, the fire brigade also came, but the fire had been burning for a long time, and there were ruins everywhere."
"When everyone was cleaning up the scene, they discovered that there was another body, which had been burned beyond recognition, just like a charcoal body."
After saying this, the old lady couldn't help but shiver, as if thinking about this situation, her hair stood on end.
"What happened next? How to deal with this matter?" Officer Wang asked.
The old lady took a sip of tea, frowned and said, "Then? Later, I remembered that the police from Wangchao Town came to dispose of the body and asked who they knew. They wanted to identify the deceased."
"But everyone said they didn't know him. After all, a charred body that was unrecognizable was quite scary to look at."
"Also, the owner of the sponge factory was arrested because he burned people to death in the factory. However, the owner of the sponge factory flatly denied that these were employees of his factory."
"Moreover, the owner of the sponge factory seriously suspected that this man sneaked into his factory at night and lit the sponges on fire, which caused the fire."
This chapter is not over yet, please click on the next page to continue reading the exciting content! "After all, how can it catch fire if everything is fine?"
After a pause, the old lady looked up at the ceiling and continued to think about it:
"Anyway, that year, I remember that no one recognized the deceased, and the owner of the sponge factory also confirmed the number of his employees, and also fully explained his situation."
"Therefore, the police handling the case here can only temporarily shelve the case and characterize it as a fire caused by an unknown fire source."
"Then...this corpse." Lu Weiwei also continued to remind.
The old lady nodded: "The body has been disposed of because this person was originally a loner. He may have come from other places to make money by playing the erhu for money."
"So, no one knows his identity, especially his erhu, which was burned to charcoal along with the fire that night."
With a heavy sigh, the old lady added: "So at that time, how to deal with the body became a problem."
"Due to his special status, the deceased's relatives could not be found for the time being, so several veteran policemen here who had not yet retired asked everyone to bury the body nearby temporarily."
"When relatives of the deceased come to the door, we can give an explanation and take the body away."
"But the wait lasted year after year, for fifteen years. No one came to collect the body for fifteen years."
"And because of the surrounding villages, everyone does not agree to bury the body in their village cemetery."
"So after some back and forth, everyone compromised and discussed burying the body on the mountain."
"Just like that, several older and enthusiastic villagers buried the body there together."
"Since no one came to visit the tomb, it is estimated that the tomb has long been covered by weeds, and not many people know its specific location."
"Yes." After hearing what the old lady said, Lu Weiwei quickly replied: "We have been near that wild grave, and the weeds around it have been cleared. It feels like all kinds of weeds are piled high."
"It can be seen that no one has come to sweep the tomb and fill the soil in these years? Just recently, the deceased named Yuan Jialiang came to the mountain for 10 consecutive days to worship this person."
"I estimate that this Yuan Jialiang is a relative of the deceased."
"But how did he know the specific location of the wild grave?" Gu Chen raised his own doubts and couldn't help but say:
"After all, it's strange that he, a foreigner, can accurately find the location of the grave."
"He can do a lot of things that locals can't do."
"Furthermore, I heard from Zhou Zheng, who lives in seclusion on the mountain, that he has lived on this mountain for so long and has visited almost every corner of the mountain, but he did not notice this wild grave."
"If Yuan Jialiang hadn't gone up the mountain to offer sacrifices and met Zhou Zheng, Zhou Zheng probably wouldn't have known yet that there was a wild tomb on the mountain."
"Yes." As soon as Gu Chen finished speaking, Lu Weiwei also agreed:
"Junior Brother Gu is absolutely right. I don't believe that no one gave Yuan Jialiang directions."
"Or maybe Yuan Jialiang knew the specific location of the tomb back then, but he didn't come here for many years. Now he suddenly remembered it and came here to pay his respects."
"Or maybe the fire was set by Yuan Jialiang back then, and it happened to burn the unidentified deceased. Out of guilt, he chose to come here to worship?"
Lu Weiwei talked a lot about her thoughts in one breath.
Gu Chen also snapped his fingers and said, "What Senior Sister Lu said makes sense. It is completely possible."
Taking a deep breath, Gu Chen continued to explain to everyone:
"Think about it, everyone, this Yuan Jialiang came to Wangchao Town from Hubei Province, booked a hotel, and stayed there for more than ten days."
"To say that he and the two channel e-commerce companies from Guangdong Province all came to participate in the Wangchao Town Blueberry Picking Festival, I don't think so."
"After all, Yuan Jialiang didn't seem to care about the Blueberry Picking Festival. From the first day he arrived in Wangchao Town, he started leaving early and returning late to go to the mountain to worship the deceased."
"It can be seen that Yuan Jialiang's purpose is very clear and he also knows the specific location of the tomb."
Crossing his arms, Gu Chen also lay on the seat and continued:
"It can be seen that if no one guides Yuan Jialiang, Yuan Jialiang can accurately find the right position."
"This further illustrates that Yuan Jialiang may have known the specific location of the tomb back then, or it may be that as Senior Sister Lu just analyzed, this Yuan Jialiang may be an arsonist."
"Because I felt guilty for burning the deceased, I came here to offer sacrifices to make myself feel better."
"Hmm." After listening to Gu Chen's analysis, Officer Wang also waved his right index finger and added:
"There is another possibility, that is, this Yuan Jialiang is related to the deceased. He learned the specific location of the wild grave through others, and then made a special trip to find it."
"The purpose is clear. He is here to worship the deceased. This shows the importance of the deceased to Yuan Jialiang. After all, he has been offering sacrifices for 10 consecutive days."
"If Yuan Jialiang hadn't been poisoned and killed on the mountain, I guess he would have continued to offer sacrifices."
"What is this person doing?" Listening to Officer Wang's explanation, Lu Weiwei felt that the situation seemed to be getting more and more complicated.
Gu Chen clapped his hands on his thighs, stood up, walked back and forth in front of everyone, analyzed and said:
"There are two conclusions now. One is that Yuan Jialiang was the culprit of the sponge factory fire that year, but he has always felt guilty because he burned the unidentified deceased."
"But when he was buried, he knew the specific location, but he never came back after leaving here."
"Then, he felt a little guilty because of the condemnation of his conscience, so he chose to come here to pay homage and sweep the graves of the deceased every day."
"As for the other kind, that is, Yuan Jialiang is a relative of the deceased, but because the bones have long been reduced to charcoal, it is impossible to tell, so we can only offer sacrifices every day for peace of mind."
…
Everyone also expressed their opinions on the identity of Yuan Jialiang and the deceased.
Soon, everyone reached a unified opinion from their differences, and then from a unified opinion to a disagreement, then to unity, and then to another disagreement...
After a heated argument, Gu Chen also said loudly: "Everyone, please be quiet."
Seeing Gu Chen speak, everyone looked at Gu Chen.
"Junior Brother Gu, do you have any ideas?" Lu Weiwei asked.
Gu Chen nodded silently: "You can compare this charred corpse with the deceased Yuan Jialiang."
"But it will be more difficult to detect. After all, this is a burnt corpse, and the other is also a cold corpse."
"I think it may be difficult to make a breakthrough between the two, but... because of the long time period, it is estimated that it will be difficult to achieve results."
At the end of the sentence, even Gu Chen himself lost confidence and his tone became hesitant.
But Zhang Wenxia said indifferently: "It doesn't matter. I believe that the municipal bureau's detection technology should have its own magic weapon."
"If the detection can be successful, it will be a big breakthrough for our profession."
"Yes." Gu Chen completely agreed with Zhang Wenxia's statement and reminded him:
"So Senior Sister Zhang, can we dig up the wild grave? Then extract relevant materials and conduct identification with Yuan Jialiang's body? See if there is any connection between the two?"
"Uh." Seeing that Gu Chen was thinking about the wild grave again, Zhang Wenxia said with some uncertainty:
"Gu Chen, this body has been burnt, and it has been 15 years. Can this...can we still do an appraisal?"
"Don't worry about this." Seeing that Zhang Wenxia was worried, Gu Chen also reminded him: "There is a high probability that it can be done."
"Higher temperatures, organic solvents, acid-base reagents, urea, amides, etc. can all cause denaturation of DNA molecules."
"That is, the hydrogen bonds between the double-stranded bases of DNA are broken and the double helix structure is unraveled, which is also called the unwinding of DNA.
After a pause, Gu Chen continued: "But the break does not disappear. Only if it can dehydrate and carbonize organic matter like concentrated sulfuric acid can it be said that DNA can be destroyed."
"As far as burned corpses are concerned, it depends on how high the high temperature is? If it is based on the high temperature in the human body, DNA at this temperature is indeed mainly unwinding and denatured."
"Afterwards, under certain conditions, it can be re-spinned after cooling down. These are also two important steps in PCR technology."
"PCR technology?" Zhang Wenxia didn't understand these professional terms, so she asked Gu Chen weakly:
"Gu Chen, what is this PCR technology?"
"PCR, the full name is polymerase chain reaction." Seeing that Zhang Wenxia didn't understand, neither did anyone else present.
Gu Chen simply explained: "It is a molecular biology technology that uses the principle of double-stranded DNA replication to amplify specific DNA fragments in large quantities outside the body."
"The characteristic is...it can use a small amount of DNA as a template to quickly amplify and obtain a large number of copies."
"PCR technology like today's has been used in many fields of modern biology and related sciences. It is also widely used in molecular biology and can be used in many fields including biomedical research, criminal forensics and molecular archaeology.
