Detective: Open your eyes, I am handcuffed in the interrogation room.

Chapter 457 Clues found, Liu Chengpu pleads guilty
The interrogation continues.

Chen Yi tried to start the conversation from the beginning, talking about Zhongluo Village, Liushouwu, Liuzhenmao, and even Liu Chengpu's parents, but Liu Chengpu was quite determined and had no intention of betraying Ding Yunjie.

As for the murder, he also kept silent.

He is not a fool. Murder and rape are two completely different concepts.

"Don't you know that you've been used by Ding Yunjie?"

……

"We are sure that you were the one who murdered Liu Shouwu and Liu Zhenmao. Even if you don't confess, we will continue to investigate. However, the sentencing for the two results will be different. Think it through."

……

"Don't think about yourself, think about your parents too."

After mentioning his parents several times, Liu Chengpu's mentality was affected to some extent, but it was still not enough.

It is very unlikely that a criminal who has been building up his mental strength for several years can be defeated with just a few words, especially when the criminal has been brainwashed by love.

"When raping He Shan, Ding Yunjie didn't ask you to wear safety measures, which led to the police obtaining your DNA. This is also the direct reason why you were arrested. She doesn't care about you at all, do you understand?"

Liu Chengpu lowered his head and said nothing.

Chen Yi raised his hand and gestured: "Turn up the air conditioner."

Low temperatures can affect willpower and make people's thinking slow, but this does not constitute mental torture.

The two of them spent more than an hour like this, and after confirming that Liu Chengpu was not likely to confess for the time being, Chen Yi got up and left the interrogation room.

It's really hard.

I don’t know how Ding Yunjie could have deceived a man to protect her so much.

"Team Chen."

Lu Minghe walked forward.

Chen Yi ordered: "Continue the interrogation. Anyone in the bureau who wants to try can do it. Except for eating, sleeping and going to the toilet, there will be no interruption."

There is strength in numbers. Chen Yi couldn't pry open Liu Chengpu's mouth, but perhaps other police officers could.

By analyzing Liu Chengpu's personality, experience, and weaknesses, an unintentional remark might be able to break down his psychological defenses.

Criminal investigation is a collective task, and what is needed is a "group fight". Individual heroism is still relatively limited and it is impossible to be effective in every case.

"Okay, I understand." Lu Minghe accepted the order.

Chen Yi went to see Ding Yunjie.

Ding Yunjie's current status is summons, and the time will not exceed twenty-four hours.

He knew that Ding Yunjie was much more difficult to interrogate than Liu Chengpu, so he did not expect her to confess and mainly chatted with her in an indirect way.

There was surveillance recording in the interrogation room. Ding Yunjie was flawless and completely portrayed herself as a victim without revealing a single flaw.

Two hours later, Chen Yi left the interrogation room again.

Zhuge Cong and his colleagues have remained silent about the final truth of the case. It would be a lie to say that they were not shocked. Throughout their investigation, the person they overlooked the most was Ding Yunjie.

Who would have thought that she was the mastermind behind it.

"You can also participate in the interrogation. I'm going to take a break and read a novel. Don't disturb me."

After leaving a message for the research team, Chen Yi stayed in the lounge, lying on the sofa with his mobile phone in his arms.

He was reading a novel written by Ding Yunjie.

Her writing style is immature and a bit literary, but in order to make money she used the template of a cool novel, writing ancient romance stories. The heroine is a villain, and she kills decisively.

There is very little romance, and the style is dark.

You can tell a person’s character by his writing. This book has a lot to do with Ding Yunjie’s experience.

The novel is a bit long, and it will take some time for Chen Yi to finish reading it.

Lao Chen and the deputy director in charge, Ma Xiang, came once during the period. After learning that the case was in the difficult final stage, they did not disturb us and everything continued.

Lu Minghe and others were reviewing the novel, while Chen Yi was reading the novel.

Twenty-four hours later, there was still no breakthrough. If we quantify the psychological defense, Liu Chengpu had only worn down 10% of it at this moment. Not to mention Ding Yunjie, who simply treated the Municipal Bureau as a vacation spot.

The only flaw that wasn't considered a flaw was a sentence that Ding Yunjie suddenly said.

"If what you said is true, then did I do something wrong?"

She asked the wrong person. The police's job is to investigate cases and arrest people, not to judge. Even if they do, they keep it in their hearts.

Lu Minghe asked Chen Yi for his opinion.

Twenty-four hours have passed, will you release him or not?

"Criminal detention." Chen Yi said.

Lu Minghe: “How many days?”

Chen Yi: “Thirty-seven days.”

Lu Minghe: "Okay, I'll report it."

Criminal detention is a compulsory measure, not a punishment. Its term is between fourteen and thirty-seven days. For major suspects who commit crimes on the run, commit crimes multiple times, or commit crimes in groups, the detention period can be up to thirty-seven days.

Two results.

First, the investigation achieved a breakthrough within thirty-seven days, the procuratorate approved the arrest, and the next step was prosecution.

Second, if the suspect is acquitted after thirty-seven days, he or she can apply for state compensation.

In most cases, arrest will be approved after criminal detention measures are taken, but this is not necessarily the case in some cases, such as this case.

Chen Yi continued to read the novel and instructed Lu Minghe to lead a team to thoroughly investigate Zhongluo Village, targeting his murder case.

Since the crime was committed in the same village, the remaining evidence and possible witnesses are all points that need to be covered in the investigation.

I'm afraid this case will continue for quite some time. Old cases are very difficult to investigate and require a bit of luck.

Chen Yi finished reading the novel in three days and automatically sorted out all the events, big and small, in his mind.

In general, it is a story about a girl who has suffered a lot and travels back to an imaginary ancient time, and then grows up step by step with her wisdom and ruthless character. She kills gods when she meets them, and kills Buddhas when she meets them.

There is no description of wolves or rape; Ding Yunjie did not write her real experiences into the novel.

However, it was still inspiring to Chen Yi.

"Shenhu?"

Chen Yi seemed to be thinking about something. Sinking in the lake was a small climax in the book. After fighting with the villain many times, the protagonist finally ordered his men to put the villain into a sack and threw him directly into the center of the lake in the middle of winter to drown him alive.

Or maybe he froze to death.

"sack?"

Chen Yi tried to reconstruct Liu Chengpu's crime process. The first thing he had to do was to make Liu Shouwu and Liu Zhenmao unconscious. This was a necessary condition.

Then, they carried the unconscious person to the Burial Valley and threw him down.

Should I carry him directly or put him in a sack?

The village is so small, and there is only one road leading to the Burial Valley from the village. If you are caught by other villagers, it would be hard to explain, so it is safer to put it in a sack. Then you can just make up something, even an animal corpse, which is better than carrying a person directly.

The process of a sack sinking into a lake and a sack sinking into a valley is the same, the only difference is the way of death.

What Ding Yunjie can think of, Liu Chengpu will also know.

"Reasonable."

Chen Yi took out his cell phone and called Lu Minghe.

At this time, Lu Minghe was almost stationed in Zhongluo Village, and launched a strict investigation into the murder of Liu Shouwu and the other two. During the three days, the two communicated by phone and found out some things. For example, Shanglu.

There is a person in the village who is in charge of mountain burials and he holds a high status in the village. Lu Minghe ignored them and forcibly searched the place, and found a lot of dried, sliced ​​and powdered herbs, which he put in bottles and jars.

Although Rhizoma Coptidis has the effect of reducing swelling and promoting bowel movements, due to its special use in Zhongluo Village, almost no villagers use it on weekdays, as it is considered unlucky.

Using shanglu means that someone in the family has died or is about to die.

After listening to Chen Yi talking about Shang Lu, Lu Minghe suspected that Liu Chengpu must have used it when he killed someone, so Lu Minghe went to investigate this time. He even saved the search warrant and broke in directly, and then made up for it later.

All the bottles have been taken back to the city bureau for fingerprint extraction, and the identification work is still in progress.

Lu Minghe suspected that Liu Chengpu had come to steal.

For example, the situation of Liu Chengpu and Liu Shouwu in the village.

Lu Minghe has completed a large number of visits and determined that Liu Chengpu had sufficient conditions to commit the crime.

Liu Shouwu had his own house, and the few of them often got together to eat and drink, but Liu Chengpu rarely attended.

The last gathering may be the time for killing.

No one could provide the exact date, and the memory has become vague as several years have passed, but it was roughly before Liu Chengpu left the village.

The concept of law in Zhongluo Village is so weak that they didn't even think of calling the police when two living people disappeared. Of course, this is also related to past precedents. It is impossible that no one in the village had the idea of ​​calling the police.

In the past, there were also young people who secretly left the village without saying goodbye and only showed up many years later. This was the information obtained by Lu Minghe and his people during their visits.

"sack?"

After answering Chen Yi's call, the word "sack" reminded Lu Minghe.

After they arrived at Zhongluo Village, they immediately searched Liu Chengpu's home, or more precisely, his room, but did not find any suspicious items or traces related to the case.

"There seems to be a sack in Liu Chengpu's room, filled with useless things. He probably has no use for it but is reluctant to throw it away. It has been in the corner for quite a while because there is a lot of dust around it."

Chen Yi: "Have you checked everything inside?"

Lu Minghe: "We checked everything and dumped all the items out. There's nothing suspicious."

Chen Yi: "Send a surveyor to check again, and be careful, especially where the sacks were dumped, to prevent any traces from being missed."

Lu Minghe: "Okay, then... where's the sack?"

Chen Yi: "Bring it back as well and hand it over to the technical detective."

Lu Minghe: "Okay."

After hanging up the phone, Chen Yi adjusted himself to a comfortable position and fell asleep in the lounge.

Maybe he was tired, he slept from the afternoon until nine o'clock in the evening without even having dinner. When he woke up, he found Zhuge Cong sitting there looking at him.

"what time is it?"

Chen Yi slept very soundly and was afraid that he would not be able to fall asleep for several hours.

"It's nine o'clock, Captain Chen." Zhuge Cong spoke. His expression was relaxed and he was smiling, as if he had something to say.

Chen Yi sat up. There was a cup in front of him. He picked it up and drank it without caring what time the water was.

"Any progress?"

Zhuge Cong nodded.

Chen Yi: "Where is Lu Minghe?"

Zhuge Cong: "He's waiting outside. He doesn't dare to go to the detention center to interrogate Liu Chengpu easily if you're not awake."

Liu Chengpu has been criminally detained and is currently being held in a detention center. Because the case has not been fully investigated, no application for his arrest has been made to the procuratorate.

"Interrogation?" Chen Yi rubbed his eyes. "What clues?"

Zhuge Cong said: "Liu Chengpu's fingerprints were found on the bottles containing Rhizoma Phragmites australis. They were well preserved. At that time, Liu Chengpu probably picked them one by one and finally took away the amount that satisfied him."

Fingerprints on glass objects can last for a very long time, and if the environment is not affected, a few years will not be a problem.

Chen Yi: "Continue."

Zhuge Cong: "In the sack... there are hairs of Liu Shouwu and Liu Zhenmao."

Seeing the chain of evidence connected, Chen Yi immediately stood up and said, "Let's go to the detention center."

Zhuge Cong: "Don't you want to eat something, Captain Chen?"

Chen Yi: "After the interrogation of Liu Chengpu, I will treat you to a celebratory supper tonight."

Zhuge Cong smiled and quickly followed.

On the way, everyone analyzed Liu Chengpu's crime process, which is now very clear.

Stealing Rhizoma Coptidis was a preparation for the crime, and then drugging was put into the meal, and then Liu Shouwu and Liu Zhenmao were put into sacks, carried all the way to the Burial Valley, and thrown down.

It is impossible to carry two people. You have to carry them separately, or kill one today and the other tomorrow.

Wolves are nocturnal animals. They usually do not show up during the day and come out to look for food at night. So when Chen Yi and his friends went to the Burial Valley last time, they only saw a few of them sporadically.

Even if they fired shots, they would not attract wolves in a short time.

"Fortunately, we used Shanglu, otherwise it would be difficult to find clues." The speaker was Lu Minghe.

Chen Yidao: "Only when we look at the case from a God's perspective can we find loopholes. There is no if. When we handle the case, we must have the belief that we can solve it."

Time cannot be reversed, and when it comes to the perfect crime, he prefers to believe that only turning back time can do it.

Only by going back to the past again and again and checking for deficiencies and filling in the gaps can the case be done perfectly.

But the suspect had no chance to make up for his mistake.

Lu Minghe nodded and said that the police must have confidence and believe that all cases can be solved, so that they can do their best.

There are indeed unsolved cases in the country’s decades of criminal investigation history, but confidence is always the best armor.

After arriving at the detention center, Liu Chengpu was taken to the interrogation room.

Compared to the good days he had at the Municipal Bureau a few days ago, Liu Chengpu felt much more lethargic tonight, and his face turned yellow from eating boiled cabbage.

There is no good food in the detention center. The food is even worse than in the detention center. In some detention centers, at least you can buy individual stir-fried dishes by yourself, but the price and quantity are much different from those outside.

Things will improve a lot when you get to prison.

Chen Yi didn't waste any time talking to Liu Chengpu and placed the copies in front of him one by one.

"Stealing rhubarb, filling it with sacks, and still saying you didn't kill anyone?"

"Liu Chengpu, stop struggling. You should know that this matter cannot be fooled away. These are two lives. Do you understand?"

Liu Chengpu was silent for a long time, and finally he said, "I threw them down."

Chen Yi: “Why?”

Liu Chengpu: "Because I don't like them, I have been bullied a lot since I was a child."

It seems that he still doesn't intend to tell Ding Yunjie.

"If that's the case, why should we become friends with them?" Chen Yi said.

Liu Chengpu: "These are two different things. We grew up in the same village and cannot become enemies."

Chen Yi: "Look up at me."

Liu Chengpu raised his head slightly, and looked at Chen Yi with his lifeless eyes.

"Think it over carefully. Do you really want to take on everything yourself? The price is your life. I repeat, the price is your life." Chen Yi said this slowly.

A reminder and also a warning.
