Chapter 921 Difficulty Level 6

"Chen Nuan is dead? Impossible!"

In the interrogation room, the victim's husband Jin Quan shook his head vigorously, making the interrogation chair rattle.

Meng Chengbiao said in a deep voice: "The body has been found. It has been compared with the DNA of her family members and the DNA of Chen Nuan taken from your home. They are all correct."

"I don't understand what you are talking about. I was in contact with her last month. It's impossible for her to be dead." Jin Quan looked a little old. If you don't look at his ID, you will think he is in his thirties. His hands are full of calluses. He clenched his fists tightly and looked like he was trying hard to hold back his grief.

Meng Chengbiao was unmoved and asked: "When was the last time you contacted her?"

Jin Quan: "Well... it was on the 25th of last month."

Meng Chengbiao lowered his head to confirm the time of death of the victim. Jiang Yuan identified it as the 17th of last month. Considering the error in Jiang Yuan's judgment of the time of death, the victim should have been dead at the time of contact mentioned by Jin Quan.

It seems that either Jin Quan is lying or the murderer is chatting with the victim's phone.

Meng Chengbiao is very calm. He has experienced many situations, whether the murderer pretends to be the victim or the murderer pretends to be the murderer pretending to be the victim.

Meng Chengbiao just asked calmly: "You said you contacted Chen Nuan on the 25th of last month. How did you contact her?"

Jin Quan replied: "WeChat."

Meng Chengbiao: "What did you say?"

"We quarreled for a few words. She said she wanted to go abroad to work with her friends. I said no, but she didn't listen to me. I asked her not to work outside before, but she didn't listen. I said I earned enough money to spend, and she said she owed too much money. I said that it was not the money for the betrothal gift, and she said it couldn't be calculated like this..." When Jin Quan talked about this topic, he kept talking endlessly, almost forgetting his own situation.

Meng Chengbiao naturally would not interrupt him, so he let him vent as much as he wanted, and at the same time made a few notes in the notebook in front of him.

After waiting for Jin Quan to finish, Meng Chengbiao asked again: "Tell me what you were doing these days before the 25th? Have you met Chen Nuan?"

"I was working on the construction site, and occasionally sent a message to my wife... We didn't meet, and I asked her to come to work with me, but she didn't want to..." Jin Quan's desire to talk became visibly stronger.

From Meng Chengbiao's point of view, Jin Quan in this state does not look like a murderer. It can only be said that the man in front of him is not a good husband recognized by the mainstream society, but the probability of a murderer is not high.

At the same time, the policeman who was playing auxiliary next to him also lit up Jin Quan's mobile phone, took a look at the several passwords on the back of the phone, quickly entered them, and then opened WeChat to start checking the chat records between Jin Quan and Chen Nuan.

What can be found out during the interrogation is closely related to the verification of evidence. As the saying goes, a lie needs countless lies to cover it up. And a series of lies is difficult to conceal.

Jin Quan's mobile phone not only has his chat records, but also records of map addresses, shopping records, mobile phone base station records, etc. If the search is detailed enough, a person's daily life can almost be completely laid out on the mobile phone.

With such evidence verification, normal people can only make up limited lies during interrogation, and coupled with the deterrent effect of powerful agencies, they basically have to confess in the end.

The same experience is actually suitable for quarrels between boyfriends and girlfriends. Find a software for meeting records, and cooperate with mobile phones and other sound collection devices to trace back every sentence, and then determine the truth and falsehood, organize debates, although the relationship may break up, but the winner can be determined.

Monitoring room.

Liu Jinghui's expression is more serious and rich than Jin Quan's.

Based on his personal experience, the probability that Jin Quan is the murderer is indeed not high.

After a while, feedback from all parties also proved Liu Jinghui's conjecture.

"Around the 17th of last month, Jin Quan was working at the construction site. He was in charge of plastering. There were six people in the team, so it was unlikely that there would be fewer people. Without people, the work would not be completed."

"The people on their construction site are all from the same hometown and are familiar with each other. The plasterers work at night, rest during the day, and play cards in the afternoon. They have little time to go out and it is basically impossible for them to go back to their hometown."

"Chen Nuan used a cousin's ID card, and her phone number was also obtained through this ID card. She has an older brother and an older sister, so she has been an illegal resident for a long time..."

"At present, Chen Nuan should have worked and lived in Changle City for a period of time, and changed her mobile phone card during this period."

The information was collected piece by piece, and gradually formed a chain of evidence.

In terms of the duck theory, when a person buys a ticket to a certain place, books a hotel in a certain place, has a mobile phone signal in a certain place, orders takeout and takes a taxi in a certain place, and even has a surveillance video confirming that she appeared in a certain city on a certain day of a certain year, then she is likely to have gone to a certain place.

Similarly, if a person has various information proving that he did not go to a certain place, then he probably did not go there.

If we think about this problem from a mysterious perspective, is it possible that Jin Quan went there and then returned and secretly killed someone, is it possible that Chen Nuan sent someone to Changle City with a full set of identity proof materials? However, if we want to put forward such a theory, we need stronger evidence to prove it.

Even Liu Jinghui, who has seen and handled many mysterious cases and imagined even more mysterious stories, has to conclude based on the current evidence: "Jin Quan should not be the murderer."

"Jin Quan's parents don't have time to kill people." Jiang Yuan analyzed along the lines of interpersonal relationships.

Liu Jinghui nodded: "They have been asked to confirm the situation of several close relatives and interested parties of Jin Quan, but at present, the probability of the man killing someone is low. Although the deceased Chen Nuan had conflicts with her husband's family, she did not follow Jin Quan's ideas. She stayed at home, but after all, she didn’t file for divorce. At present, her husband’s family probably doesn’t have enough motive to kill.”

My dear, there is more to come after this chapter. Please click on the next page to continue reading. There will be more exciting chapters later!

The purpose of searching for the source of the corpse is to find the murderer based on the interpersonal relationships of the deceased. As for Chen Nuan's situation, the most likely murderers are the Jin Quan family.

The suspect was gone, and the case instantly returned to a confusing state.

"Where is the Chen family?" Jiang Yuan looked through the information.

Liu Jinghui slowly shook his head: "The Chen family is in the same situation. There is no motive for murder. Judging from the current case, the most likely factors that will lead to Chen Nuan's death are either financial factors or emotional factors. If Chen Nuan chooses to divorce If they remarry, given the current circumstances, the Chen family can easily get more than 200,000 to 300,000 yuan in gift money. Even if part of the previous gift money has to be refunded, at most, only half of it will be refunded. In this way, the Jin family is financially secure. He was damaged and probably emotionally hurt, but this is all based on the premise that Chen Nuan filed for divorce."

Liu Jinghui patted the information in front of him gently with his hand, and continued: "Chen Nuan is a weak woman. If she wants a divorce, she must get the support of her mother's family. From what we know, Chen Nuan is not very strong. Personality, while living in Yuefeng Village where the Jin family is located, his personality was relatively gentle... Judging from the information fed back by the Chen family, Chen Nuan did not talk about divorce, and the dissatisfaction he expressed was mainly based on Economic situation..."

"The living conditions in the village are definitely not very good." Jiang Yuan is well aware of this. Jiangcun was considered a big village before it was demolished, and overall the living conditions are not as good as the current Jiangcun community.

Liu Jinghui nodded and said: "However, the conditions of Chen Nuan's own family are even worse. All the gifts her sister received for her marriage were used for her brother's marriage, which was not enough. Moreover, the money she owed was paid back with Chen Nuan's money from her marriage. So, when Chen Nuan lived at home, his living conditions were not as good as those of the Jin family, so he was still able to adapt to Yuefeng Village. "

Wang Chuanxing said from the side: "From the information we collected, many people in Yuefeng Village go out to work, so people still don't like living in the countryside. This should also affect Chen Nuan. There are many young couples in Yuefeng Village. They went out to work together, but the construction site where Jin Quan worked had high wages and poor conditions, which was not suitable for a young couple to work together, so Chen Nuan was left in his hometown. The two had many conflicts in this regard. "

"The little girl prefers to live in the city. At least, she doesn't want to live with her mother-in-law." Liu Jinghui concluded in one sentence: "There are conflicts, but they will not lead to death."

"In this case, the road of interpersonal relationships will no longer work?" Wang Chuanxing sighed longly: "If it is a random killing, it will be troublesome."

The theory of searching for the source of a body in a drowning case is similar to that of dumping a body, both of which are based on the premise that the suspect does not need to do a lot of unnecessary work. To a certain extent, a drowning case is actually a case of a body thrown into the water, but because the body moves with the water, it further increases the difficulty of finding the source of the body.

And if such a case involves random killings, it would be too difficult to detect.

Of course, any random killing without purpose is difficult to detect, which is one of the reasons why you must be on guard when encountering a serial killer.

Jiang Yuan shook his head slightly at this time and said: "It is true that random killings cannot be ruled out, but I think we should not consider random killings for the time being. How is the situation at Chen Nuan's working place, and how are the newly established interpersonal relationships?"

The main physical evidence in Chen Nuan's case was a corpse and the clothes he carried with him, which Jiang Yuan had carefully examined. Based on what he knew so far, Jiang Yuan did not think he could find the murderer through physical evidence.

In other words, if it were to be considered a random killing, the case would basically be shelved. If we want to investigate again later, either the murderer has committed another crime, or he has committed a crime before, and the case can be merged, or there is other evidence later, or other witnesses emerge. Otherwise, it will be extremely difficult to solve the case. Yes, maybe it will go up to LV6.

Faced with this situation, Jiang Yuan's idea was naturally to exhaust other possibilities first.

If other possibilities are no longer possible, let’s talk about LV6.
