Chapter 921 Difficulty Level 6

"Chen Nuan is dead? Impossible!"

In the interrogation room, the victim's husband Jin Quan shook his head so hard that the interrogation chair rattled.

Meng Chengbiao said in a deep voice: "The body has been found. We compared it with the DNA of her family members and also compared it with the DNA of Chen Nuan that we collected from your home. They all matched."

"I don't understand what you're talking about. I was in contact with her last month. It's impossible that she's dead." Jin Quan looked a bit old. If you didn't look at his ID, you would think he was in his thirties. His hands were covered with calluses, and he clenched his fists tightly, as if 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: "Um...it was on the 25th of last month."

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

It seems that either Jin Quan is lying or the murderer is using the victim's phone to chat.

Meng Chengbiao was very calm. He had experienced many situations, whether the murderer disguised himself as the victim or the murderer pretended to be a 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 had a few arguments and she said she wanted to go abroad to work with her friends. I said no, but she didn't listen to me. I had asked her not to go out to work before, but she didn't listen. I said the money I earned was enough to spend, but she said she owed too much money. I said that was not the betrothal money, and she said it couldn't be calculated that way..." When Jin Quan started talking about this topic, he kept talking endlessly and almost forgot about his own situation.

Meng Chengbiao naturally would not interrupt him, so he let him vent freely and 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 in the days before the 25th? Have you met Chen Nuan?"

"I work at a construction site and occasionally send a message to my wife... We haven't met. I asked her to come work for 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 mainstream society, but the probability of him being a murderer is not high.

At the same time, the police officer who was assisting nearby also turned on Jin Quan's mobile phone, took a look at the several passwords on the back of the phone, typed them in quickly, then opened WeChat and began to check the chat history between Jin Quan and Chen Nuan.

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

Jin Quan's mobile phone not only contains his chat records, but also map address records, shopping records, mobile phone base station records, etc. If you check it in detail enough, you can almost completely unfold a person's daily life on the mobile phone.

With such evidence verification, normal people are limited in the lies they can make up during interrogation. Coupled with the deterrent effect of powerful agencies, they will basically confess in the end.

The same experience is actually suitable for arguments between boyfriends and girlfriends. Find a meeting recording software and use it with sound collection devices such as mobile phones. You can trace back every sentence, determine the authenticity, and organize a debate. Although it may break up the relationship, it can determine the winner.

monitoring room.

Liu Jinghui's expression is more serious and richer 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 confirmed Liu Jinghui's guess.

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

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

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

"From what we can see, Chen Nuan probably went to Changle City to work and live for a while, and during that time she changed her phone card,"

As pieces of information were gathered together, a chain of evidence gradually formed.

According to the duck theory, when a person buys a ticket to a certain place, books a hotel in a certain place, has a cell phone signal in a certain place, orders takeout and takes a taxi in a certain place, and there is even surveillance video confirming that she appeared in a certain city at a certain day and time in a certain year, then she has most likely gone to that 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, it is not impossible that Jin Quan went there and came back to kill people secretly, and it is not impossible that Chen Nuan sent someone to Changle City with a full set of identity proof documents. However, if we want to put forward such a theory, we need stronger evidence to prove it.

Even Liu Jinghui, who had seen and handled many bizarre cases and imagined even more bizarre stories, had to conclude based on the current evidence: "Jin Quan is probably not the murderer."

"Jin Quan's parents don't have time to kill people." Jiang Yuan analyzed based on the idea of ​​interpersonal relationships.

Liu Jinghui nodded: "We have asked them to confirm the situation of several close relatives and interested parties of Jin Quan, but at present, the probability of the man committing murder is not high. Although the deceased Chen Nuan had conflicts with her husband's family and did not stay at home as Jin Quan wanted, she did not file for divorce after all. At present, her husband's family should not have enough motive to kill."

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

Now that the suspect was gone, the case suddenly became confusing again.

"Where are the Chen family?" Jiang Yuan was looking through the information.

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

Liu Jinghui gently patted the information in front of him and continued, "Chen Nuan is a weak woman. If she wants to divorce, she must get the support of her family. From what we know from all sides, Chen Nuan is not a very strong person. During the time she lived in Yuefeng Village where the Jin family is, her personality was relatively gentle... And from the feedback from the Chen family, Chen Nuan did not mention that she wanted a divorce, and the dissatisfaction she expressed was mainly based on the economic situation..."

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

Liu Jinghui nodded and said, "However, Chen Nuan's family conditions are even worse. All the gifts her sister received when she got married were not enough for her brother's wedding, and they owed money, which was repaid with the money from Chen Nuan's marriage. Therefore, when Chen Nuan lived at home, her living conditions were not as good as the Jin family. She was able to adapt to Yuefeng Village."

Wang Chuanxing said, "From the data we have collected, many people in Yuefeng Village work away from home, so they don't like living in the countryside, which should have affected Chen Nuan. Most young couples in Yuefeng Village work away from home together, but the construction site where Jinquan works has high wages and poor conditions, which is not suitable for young couples to work together, so Chen Nuan was left in her hometown. The two have 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 summed it up in one sentence, saying, "There are conflicts, but they are not fatal."

"In this case, the path of interpersonal relationships is not feasible?" Wang Chuanxing sighed deeply: "If it is a random killing, it will be troublesome."

The theory of finding the source of the 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 dumping a body in the water, but because the body is carried away by the water, it further increases the difficulty of finding the source of the body.

In a case like this, if it was a random killing, it would be very difficult to solve.

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

Jiang Yuan shook his head slightly at this time and said, "We can't rule out random killings, but I think we shouldn't consider it for the time being. How is Chen Nuan's work place, and how are the new interpersonal relationships?"

The main physical evidence in Chen Nuan's case is a corpse and the clothes she carried with her. Jiang Yuan has carefully examined these. Based on what he knows so far, Jiang Yuan doesn't think he can find the murderer through the physical evidence.

In other words, if it is determined to be a random killing, the case is basically shelved. If you want to solve it later, either the murderer has committed another crime, or has committed a crime before and can merge the case, or there is other evidence or other witnesses later. Otherwise, it will be extremely difficult to solve the case, and you may need to be at level 6 or above.

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

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