Since it takes time to investigate DNA samples, Gu Chen led the team back to Furong Branch.
The next morning, everyone came to the office early, mainly waiting for the test results from the pancake boss's hometown.
You should know that ordinary DNA testing often takes a long time, but from a professional perspective, if it involves case investigation, this testing cycle can be greatly shortened.
In fact, the DNA testing time can be divided into three parts. The first is the entrustment acceptance time, the second is the pre-processing time of the test materials, and the last is the testing and comparison time.
However, the commission acceptance time is the most uncertain factor, and the speed depends mainly on the nature of the case and its impact.
Therefore, once it involves murder cases and some cases with widespread social impact, the time can often be shortened a lot.
There is also the difference in the pre-processing time of the inspection materials, such as trace evidence at the scene, bones and hair on the corpse. The processing time of these inspection materials will be longer and more troublesome.
But if it is blood, it can be processed quickly, especially this time Gu Chen's team found many blood samples at the home of mine manager Zhao Deming.
These blood tests actually don't take much time, but what needs to be determined now is whether the blood is related to the missing pancake proprietress?
After all, the investigation results showed that the pancake proprietress and these blood samples were all type AB.
But for now, Gu Chen's team has no way to obtain the blood sample of the pancake proprietress, so it is difficult to judge.
But the child of the pancake proprietress has matching DNA with the pancake proprietress.
That's why Gu Chen's team wanted to extract blood samples from the children of the pancake proprietress's hometown for matching.
If there is a successful match with the pancake proprietress, it means that the blood samples found in Zhao Deming's home are all related to the pancake proprietress.
It can also be confirmed that the pancake proprietress did appear at Zhao Deming's home.
Therefore, this is currently the focus of the investigation by Gu Chen's team.
This can also shorten the pre-processing time, and then the detection and comparison time of DNA samples.
DNA testing only amplifies the DNA and then sequences the DNA, all of which are automated.
After the map is produced, an experienced DNA tester can immediately digitize the map.
Digitization is just a row of numbers, and the two rows of numbers are compared together. If there is no need to queue and the test material is blood, then a DNA test report only takes 3 to 4 hours.
Gu Chen’s team has also conducted DNA sample testing many times before.
The current internationally accepted DNA testing method is STR, which is short tandem repeat sequence typing test.
The first step is to perform PCR, or polymerase chain reaction amplification, on the blood or DNA sample.
The second step is to use capillary electrophoresis typing detection. Each person analyzed has its own unique DNA repeat pattern.
Therefore, by comparing it with the basic map, you can confirm whether the corpse and the perpetrator are the same person.
The DNA analysis and testing technology has matured, and the test results are accurate.
Whether it is an old corpse or a highly decomposed body tissue, it can be tested.
The Gu Chen team used blood testing, so its reliability cannot be doubted.
Because the arrangements at the pancake boss's hometown were delayed a lot, Gu Chen's team didn't receive a call from Gao Chuanfeng until around noon.
Without saying anything, Gu Chen directly opened the answer button: "Gao Chuanfeng, how do you do?"
"Gu Chen, we have already matched the DNA sample test you requested."
"Just tell me the result." Gu Chen said.
"Yeah." Gao Chuanfeng didn't hide it, and said straightforwardly: "This blood test sample, we analyzed and found that it can be matched."
"In other words, the test of these two blood samples can confirm that the two people are related?" Gu Chen said again to confirm.
"Yes, it is indeed a kinship. The sample you sent is indeed the blood sample of the missing woman." Gao Chuanfeng said.
At this moment, Gu Chen was also stunned on the spot.
In Gu Chen's opinion, his suspicion of mining manager Zhao Deming was not wrongly blamed on him.
All suspicions point to Zhao Deming.
Although Gu Chen still doesn't know why Zhao Deming wanted to kill the pancake proprietress? However, Zhao Deming must have something to do with it.
"Gu Chen, Gu Chen, are you listening?" Seeing that Gu Chen didn't respond for a long time, Gao Chuanfeng continued to call.
"I'm listening. Thank you, Gao Chuanfeng. With your test report, I know what to do next."
"That's good." Seeing that Gu Chen already had a plan for the next step, Gao Chuanfeng also agreed and said, "If you need any help, remember to tell me at any time."
"Okay, so be it."
The two exchanged a few simple greetings and hung up the phone.
At this moment, Gu Chen was very clear that what he had to do now was to find Zhao Deming and investigate the situation clearly.
What if Gu Chen couldn't tell whose blood the previous blood belonged to? But those evidences were enough to prove what had happened in this house?
It's just that Gu Chen didn't have enough evidence at the time, but now, Gu Chen has reason to believe that Zhao Deming can't escape the relationship.
…
…
2pm.
Interrogation Room No. 1, Furong Branch.
Zhao Deming was called here.
This time, Zhao Deming looked at everyone's expressions a little strange. He couldn't tell what was wrong. But it seemed that Gu Chen's team looked at him with firm eyes.
Zhao Deming asked weakly: "Officer Gu, have you found out through the investigation? We still have a lot of work in the mining area that I need to handle, and I don't have time to stay here with you to investigate."
"You don't have to worry." Seeing Zhao Deming start to complain, Lu Weiwei said casually.
Afterwards, Lu Weiwei opened the record book, looked at Zhao Deming and said:
"Zhao Deming, you said you don't know who put the bloody rags and paper balls found under the bed in your bedroom, as well as the bloody blade found in your storage room?"
"Yes." Faced with Lu Weiwei's question, Zhao Deming still nodded in agreement:
"I really don't know who put it in my house because I've never seen these things."
"Then let me tell you." Lu Weiwei slapped the table and said angrily:
"That blood came from your friend. You said she disappeared in the guest house, but all the blood belongs to her."
"You...what did you say?" Facing Lu Weiwei's questioning, Zhao Deming, who was sitting on the interrogation chair, suddenly froze on the spot, his face looking surprisingly ugly.
"Zhao Deming, how long are you going to keep pretending?" Officer Wang looked at Zhao Deming and said angrily.
"No...no." Zhao Deming took a deep breath and said slowly:
"Comrade police, you...did you make a mistake? You must have made a mistake."
"Did we make a mistake?" Officer Wang snorted and said angrily, "Did we make a mistake or are you unwilling to admit it?"
"Let me tell you Zhao Deming, we used DNA testing to match the DNA blood samples of your friend's children. Only then can we determine who these blood samples belong to?"
"But in the end, the result we got was that it was the blood sample of the pancake proprietress."
"But you said that she lost contact with her in the guest house. It seems that you can completely put aside the relationship between you. But have you ever thought that these evidences that you have no time to collect can completely expose your lies?
"
"No, that's not the case. There must be something wrong somewhere." Faced with Officer Wang's questioning, Zhao De was obviously panicked and frightened out of his mind.
Yuan Shasha sighed and said slowly: "I tell Zhao Deming, we have solid evidence."
"You also said before that your family members have not stayed in the villa in the mining area for half a month."
"This only means that you are the only one living in that villa."
"Besides, you are the only one who has the key, and there are no signs of the door being broken."
"Moreover, these bloody rags and paper balls, as well as the bloody knife blade in the storage room, were all found in your house."
"Even if it was the murderer, he couldn't be stupid enough to just throw these things away at the scene, right?"
"It can only mean that this is evidence that you did not have time to destroy after committing the crime, so you could only temporarily hide it in some corner of your home."
"You wanted to wait until the limelight passed before handling the evidence, but our police found you."
"No, no, it's not what you said." Faced with Yuan Shasha's question, Zhao Deming was flustered.
There was fear in his eyes, as if he had absolutely no possibility of excuse.
However, Zhao Deming tried his best to explain for himself: "Comrade police, you have to believe me, I must be unjust."
"Think about it, the evidence you found? Has the blood been dried for many days?"
"That's right." Officer Wang nodded silently.
Zhao Deming quickly added: "Doesn't this mean that these things have been abandoned in my house for many days?"
"If I have so many days, why don't I get rid of these items as soon as possible? Why do I keep them at home?"
"Does it do me any good to keep these things in my home? There is no benefit at all."
"But what does this mean? It can only mean that you were too late to deal with it, or you didn't know how to deal with it for the time being, but you happened to be found by our police." Officer Wang also said righteously.
Zhao Deming was suddenly flustered and said with a frustrated look on his face: "Comrade police, how can I explain to you? I really didn't do this."
"I really don't know who sneaked into my house and put these things in my house?"
"I must have been wronged by others. It must have been a complete frame-up for me."
After a pause and trying to calm down, Zhao Deming added, "I also want to know where my friend is now."
"I said, if it weren't for those very busy days, I would definitely contact my friend as soon as possible."
"But, just because I was busy and didn't contact her, do I have to be held responsible for all this?"
"I can't wash myself away even if I jump into the Yellow River."
Faced with the questioning from Gu Chen's team, Zhao De was obviously very impatient and seemed to be completely injured after being wronged.
However, after all, these bloody objects were found in Zhao Deming's home.
Even if Zhao Deming talks a thousand words and ten thousand words, he still can't get rid of the relationship.
Seeing that Zhao Deming seemed to have lost his soul at this moment, Gu Chen also said slowly:
"You said you were wronged, but you didn't have any evidence to prove your innocence."
"I don't know what all this is about?" Looking at Gu Chen, Zhao Deming also looked frustrated and continued:
"Comrade police, please believe me. I must have been wronged. Someone wants to frame me. It must be true."
"Okay." Faced with Zhao Deming's rebuttal, Gu Chen also gave him a chance to explain and said:
"You said you were wronged, so let me ask you, have you offended anyone recently?"
"this……"
As if he was dumbfounded by Gu Chen's question, Zhao Deming was stunned on the spot.
When Lu Weiwei saw this, she quickly reminded: "Is there someone you have offended?"
"It's certain to offend people." Zhao Deming sighed softly, and said helplessly:
"Comrade police, let me tell you the truth. As the senior manager of the mining area, I, Zhao Deming, must have conflicts with the employees and managers in the mining area."
"First of all, I represent the interests of the boss and manage these people. Anyway, I am the bad guy, and the boss hides behind him and acts as the good guy."
"So, in the mining area, I am the bad guy. Whatever the boss can't do, he lets me do it."
This chapter is not over, please click on the next page to continue reading! "Although I won the respect and trust of my boss in the mining area, I also offended everyone in the mining area."
With a heavy sigh, Zhao Deming shook his head helplessly: "So, you ask me, who have I offended? It's hard for me to answer this."
"Because I have offended so many people that I can't even count them. Even the doorman doesn't like me."
"Are you so unpopular?" Officer Wang was also stunned when he heard Zhao Deming's complaint.
"Isn't it?" Looking at Officer Wang, Zhao Deming said helplessly: "I am just a part-time worker. Even if I am a leader, one person is inferior to ten thousand people, but I am still a part-time worker after all."
"Offending people? In my opinion, it's normal in the mining area. However, it's me who offends people, so there's no point in using my friend as an excuse, right?"
"Besides, this is the first time for my friend to come to my place. She has not offended anyone before. Why should we target her? I don't understand."
After the words fell, Zhao Deming also sighed heavily, as if he couldn't understand what happened during this period.
The atmosphere at the scene suddenly became awkward.
After Lu Weiwei thought for a moment, she continued to question Zhao Deming: "I say Zhao Deming, you said you have offended many people, this is too general."
"You'd better tell me something specific. Who is it that you have had a deep hatred against during this period of time?"
"Have a deep hatred? Everyone here feels like they have a deep hatred for me."
"Don't bullshit me." Seeing Zhao Deming's answer to the question, Lu Weiwei complained and continued:
"You'd better find a few for me, otherwise the gods won't be able to help you."
After the words fell, Zhao Deming was really panicked.
The whole person started to get confused.
But no matter how Zhao Deming thinks, it always seems difficult to find a matching person.
A few minutes later, Officer Wang, who was impatient with waiting, knocked on the table and reminded:
"I asked Zhao Deming, have you thought about it?"
"Comrade police." Looking up at the crowd, Zhao Deming said with a bitter face: "I'm sorry, I really can't figure out who it is?"
"You..." Upon hearing what Zhao Deming said, Officer Wang's lungs almost exploded with anger.
But Zhao Deming said righteously: "I know that if I mention a few people, it may alleviate a lot of suspicion for me, but I always feel that these people only have work conflicts with me, and they are not serious about me.
Friends start."
"Moreover, my friend came to see me, so I had dinner with her and then sent her to the guest house."
"This time is short enough. To be able to harm my friend in such a short period of time and hide the bloody objects in my home, I feel that this is simply impossible."
With a faint sigh, Zhao Deming also continued: "So I think that these people who have conflicts with me are just because of work conflicts and will not attack my friends at all."
"So you asked me to name these people. I'm sorry, I really can't. They are definitely not the murderers."
At the end of his speech, Zhao Deming became depressed.
When Yuan Shasha saw this, she also sighed and said: "I can't tell, you still have some conscience. At least you know that those people have nothing to do with this matter."
"However, since you can't tell who has conflicts with you now, these bloody objects were all found in your room."
"Then, this suspect can only be you."
"Comrade police." As soon as Yuan Shasha finished speaking, Zhao Deming was already frustrated and said with choked sobs:
"I really don't know who is trying to harm me. Really, I consider myself a good manager."
"Over the years, I relied on being the boss's lackey and solving various problems for him, and I was able to gradually become the senior manager of this mining area and become the talker here."
"However, the people I offended were all my colleagues at work. I thought that everything was done for the sake of the economic interests of the mining area, and everyone saw this."
"Although I often harm the welfare of employees in the mining area, after all, everyone can make more money when they are working. This is real."
"I won these orders step by step."
After a pause, Zhao Deming added: "It can be said that without me, Zhao Deming, the mining work in this mining area and the entire operation would only be one day at a time."
"It is absolutely impossible to achieve today's benefits. If you don't believe it, you can ask the old employees in this mining area."
"After all, this mine was just a mine on the verge of bankruptcy before our boss acquired it."
"It is precisely because of the funds brought by our boss and my hard-working management that we have achieved today's achievements."
"They scolded me, but they only scolded me verbally, but they still admired me in their hearts. It was me who allowed them to be in the class."
Speaking of this, it seems that all the emotions that have been suppressed for a long time can burst out at this moment.
After saying these words, Zhao Deming seemed to be in a much better mood.
Looking at the Gu Chen team in front of him, Zhao Deming sighed heavily and then said slowly:
"Comrade police, no matter how much you doubt me, I won't blame you. After all, the bloody things were all found in my house."
"However, I also ask you to investigate carefully. Who is setting me up? Why did you sneak into my home and put these things in my home?"
"Besides, putting it under the bed where I sleep is terrifying to think about."
"If the murderer can come to my house unscrupulously, it means that when I sleep at night, the murderer can probably hide under my bed."
Taking a deep breath, Zhao Deming also shrank his neck and couldn't help but said: "It makes people feel terrible just thinking about it."
"Okay." Seeing that Zhao Deming said so sincerely, Gu Chen nodded silently and echoed:
"We will investigate the things you mentioned carefully."
This chapter is not over yet, please click on the next page to continue reading the exciting content! "But, for now, you must fully cooperate with our investigation."
"No problem, you can investigate it however you want. As long as you can get rid of my suspicion, I will cooperate in anything."
Zhao Deming has absolutely no choice now.
After all, Zhao Deming is also a smart man, and these bloody evidences are enough to make him the murderer.
But Zhao Deming didn't seem to want to give up, and tried his best to defend himself.
Of course, his excuses did make Gu Chen feel a little sincere.
It seems that Zhao Deming will not give up unless he helps him find the guy who framed him.
"Officer Gu." Seeing Gu Chen clearing away the documents on the table, Zhao Deming also asked weakly:
"What do we do now?"
"Go to your residence." Gu Chen put the documents on the table, paused, and then said:
"You said someone framed you, well, I'll give you a chance to help us find this guy who framed you."
"Thank you." Faced with Gu Chen's words, Zhao Deming was stunned, and then quickly lowered his head to express his gratitude.
Here, Zhao Deming knew very well that the only one he could rely on now was Gu Chen.
…
…
At 4 o'clock in the afternoon, a group of us drove to the residential area of the mining area.
At this time, Zhao Deming's residence had long been sealed off by Wu Xiaofeng and Ji Zhe, and a cordon was set up.
Because everyone found bloody objects in Zhao Deming's home, it became a crime scene.
This time, Gu Chen also brought many detection tools, preparing to restore traces of the scene.
So Gu Chen brought Rumilo, which restored the blood.
Even if the blood was erased by the murderer, it can still be restored with Lumilo.
Therefore, after everyone arrived in the living room, Gu Chen asked Officer Wang to take Yuan Shasha, Wu Xiaofeng, and Ji Zhe to the area where the blood sample objects were found, which was Zhao Deming's bedroom and the storage room.
Under the guidance of Officer Wang and Yuan Shasha, the work progressed smoothly.
Gu Chen and Lu Weiwei stayed in the living room, waiting quietly with Zhao Deming.
Not long after, Officer Wang and others came down from upstairs.
Seeing this, Gu Chen quickly asked: "Senior Brother Wang, how are you doing?"
"Harmful!" Officer Wang sighed heavily and said helplessly: "We used Lumilol reagent to test the bedroom and the utility room, and no traces of other blood were found."
"This shows that there are no signs of fighting in the room."
"Okay." After hearing this answer, Gu Chen nodded silently and said, "Then it's best to test other places as well."
"Perhaps the bedroom and utility room were not the first crime scenes."
"Understood, so I am going to take everyone to check one by one." Officer Wang also knew that the bedroom and utility room may not really be the scene of the first crime.
Therefore, prepare to continue the carpet investigation.
However, as the investigation work continued to progress, the time soon came to 5 p.m.
When everyone returned to the living room again, Officer Wang still shook his head: "Now only the living room has not been tested."
"Let's go out." Gu Chen looked at Zhao Deming and motioned to go out with everyone and give up the living room.
Zhao Deming did not refuse and followed everyone out directly to the police car at the door.
Not long after, all the testing work was completed, and Officer Wang walked out of the living room and came to the door.
Gu Chen looked around, and Officer Wang shook his head directly.
Gu Chen sighed quietly and said helplessly: "It seems that your home is not the first crime scene."
"Does that mean that this matter has nothing to do with me?" After hearing Gu Chen's words, Zhao Deming quickly asked.
Lu Weiwei on the side responded back: "What are you thinking? This can only mean that your home is not the first crime scene, but what if you committed the crime outside?"
After the words fell, Zhao Deming was suddenly speechless.
Of course, Zhao Deming also knew that for now, he could only rely on the police investigation, otherwise he would definitely not be able to escape suspicion, so he didn't say anything.
Lu Weiwei looked at Zhao Deming's business car and reminded him: "Old Wang, check if there is anything going on in his car."
"Wait a minute." After hearing Lu Weiwei's words, at the request of Officer Wang, everyone began to investigate Zhao Deming's commercial vehicle.
But after a lap of testing, there were no abnormalities inside or outside the car.
Seeing this scene, Zhao Deming also breathed a sigh of relief and faced Gu Chen and said:
"Officer Gu, I know that you are prejudiced against me now because these bloody objects appear in my home."
"But one thing is, I have never wanted to harm my friend. She and I have been friends for a long time, and we have a very good relationship as colleagues, like close buddies."
"When I first joined the company, I was still a clueless young person. She helped me a lot. You can know this if you investigate."
"With such a good friend, why would I harm her for no reason? Also, she came here to chat with me to relieve her boredom just because she was depressed and distressed."
"I just treated her well and invited her to dinner, that's all. Did I do something wrong?"
"You didn't do anything wrong? But the mistake is that these bloody objects appeared in your home."
Facing Zhao Deming's true confession, Gu Chen glanced at him and said truthfully:
"Don't complain. If what you say is true, then I hope you are fine."
"But if you lied, then we can also investigate it."
"What you have to do now is cooperate with our police investigation."
"Cooperate, of course I will cooperate." Facing Gu Chen's lecture, Zhao Deming had no choice but to nod in agreement.
Later, Gu Chen asked Wu Xiaofeng to take Zhao Deming back to the police car and stand by.
And he came to the vicinity of Zhao Deming's house and carefully checked the surrounding situation.
Because bloody items were found in Zhao Deming's house, and Zhao Deming's friend, the pancake proprietress, came to look for him before he disappeared.
This chapter is not over yet, please click on the next page to continue reading! Therefore, Zhao Deming is a major suspect, so Zhao Deming's residence was temporarily blocked by the police as a crime scene.
At this moment, Zhao Deming's house was surrounded by police cordons.
When Gu Chen walked to another nearby villa, a six or seven-year-old girl was sitting on her bicycle, looking quietly in Gu Chen's direction.
Gu Chen also noticed her, so he took the initiative to walk up to the little girl.
The little girl didn't seem to be afraid of strangers. She rode her bicycle and stayed in front of her house from beginning to end.
"Little sister, do your family live here?" Gu Chen said, pointing to the villa behind the little girl.
The little girl looked back and said quickly: "Yes, my family lives here."
"Then your family is the leader of this mining area?" Gu Chen squatted down and kept a level position with the little girl.
The little girl nodded silently: "Yes, my father is the director of the mine."
"Oh." After hearing what the little girl said, Gu Chen probably knew that this might be one of the main managers of the mining area.
Since there are three leaders in the mining area, they are in charge of daily production and management.
Gu Chen guessed that this little girl's father was probably one of the three leaders in the mining area.
So Gu Chen asked again: "Then do you know who lives in this house?"
Seeing Gu Chen pointing to the building behind her, the little girl nodded silently and said in cooperation:
"I know, this is Uncle Zhao's house."
"Then are you familiar with this Uncle Zhao?" Gu Chen asked again.
"Well, we are neighbors, and Uncle Zhao often buys me snacks." Seeing Gu Chen ask this question, the little girl said innocently.
"Then you must have a good relationship with this Uncle Zhao?" Seeing this, Lu Weiwei also came over and asked.
"Yes, Uncle Zhao is a very nice person." After the words fell, the little girl suddenly pretended to be mysterious, blocking her right hand to the left, making a whispering gesture, and told Gu Chen:
"Let me tell you quietly, Uncle Zhao is usually very fierce, and he is very cruel to other uncles and aunts in the mining area, but he never loses his temper with me because my father is the director of the factory."
"Haha." Seeing the little girl's quirkiness, Lu Weiwei couldn't help but laugh twice and said slowly:
"So, do you think Uncle Zhao treats you well because of your father's sake?"
"Well, Uncle Zhao still has to give my father's face." Faced with Lu Weiwei's teasing, the little girl didn't seem to take it at all.
When Gu Chen heard this, he also smiled and said: "Then you should spend every day at home, right?"
"Most of the time." Faced with Gu Chen's inquiry, the little girl also told the truth.
Gu Chen was very satisfied and asked again: "Then you should know who usually goes to your Uncle Zhao's house, right?"
"Yes." The little girl continued to nod: "Yes, who asked Uncle Zhao to live next door to me?"
