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

That night, Chengnan Branch.

The comprehensive autopsy results have come out. Gou Qiwen did not take any drugs that could cause coma during his lifetime, and there were no other wounds on his body.

Li Antai has listed Gou Junyong as a major suspect, and immediately started interrogating him after returning to the branch, which lasted for three hours so far.

There is gain, but no results.

Gou Junyong was quite shocked when he learned that the police suspected that he committed murder intentionally. The suspicion was obviously a reaction after being exposed for doing bad things, but he insisted that Gou Qiwen's death had nothing to do with him.

When he was in the village before, Li Antai conducted a large number of targeted visits, hoping to find people who had seen Gou Junyong out in the early morning, but he could not find them.

The village is no better than the city, and there are not many entertainment activities. At night, every household stays behind closed doors, and mobile phones are the best way to spend time.

If no witnesses can be found, Gou Junyong’s lies cannot be exposed.

In addition, Li Antai also asked people to check the few surveillance cameras in the village, and still found no trace of Gou Junyong going out in the early morning.

There are many blind spots in surveillance, and the police are not very lucky.

In other words, Gou Junyong deliberately avoided surveillance.

He is from this village. He has lived here for twenty or thirty years since he was a child. He is very familiar with the village and can walk with his eyes closed. It is easy to avoid surveillance.

If you want Gou Junyong to let go, you need other methods.

…

The research team arrived in Jiangcheng.

Jiangcheng is a place that is relatively familiar to Chen Yi. Strictly speaking, he has experienced two things.

The first thing is to serve as the leader of the task force to investigate a serial murder case spanning fifteen years.

The second thing was that he was picked up by a tourist boat here, and then landed on Qifeng Island to start a bloody battle with criminals.

It's somewhat "emotional".

The Jiangcheng City Bureau expressed a warm welcome to the arrival of the research team. They were basically acquaintances, so there was no need to say any more polite words and they went straight to the hotel and had two drinks first.

The director of the municipal bureau personally accompanied him, and after exchanging pleasantries, we quickly talked about work.

Since it is a criminal investigation, the director in charge Ge Quanshan and the detachment leader Zhao Qiming must express their stance and cooperate unconditionally. They will do whatever the investigation team tells them.

After three rounds of drinking, Zhao Qiming was quite sad. After three days of farewell, everyone looked at each other with admiration. Chen Yi was already far ahead.

The last time he came to Jiangcheng, he was ordered to face a crisis as the deputy captain. Now he was going to the local area for investigation as the deputy captain. The short time gave Zhao Qiming a strong sense of unreality.

“Team Chen, here’s to you.”

Zhao Qiming picked up the wine glass.

He did not resist the arrival of the investigation team. Since he was promoted to the detachment leader, Jiangcheng's criminal investigation work has not been perfect, but there have been no major mistakes. After Wang You was arrested, old cases with bad influence no longer exist, so he is Chen Yi regarded it as a reunion of friends.

Chen Yi thought the same way, picked up the cup and clinked it with the other party. If there were no unexpected events, the research team would stay in Jiangcheng for about half a month.

If you don’t want to leave, the time can be extended, but the provincial department will not go online.

"What kind of criminal cases occur frequently in Jiangcheng?" Chen Yi asked in a casual tone at the end of the wine bureau.

Zhao Qiming: "Theft and fraud."

Chen Yi took a sip of water and said, "Is it because the antique trade in Jiangcheng is relatively developed?"

Chen Yi has already seen the prosperity of Jiangcheng's antique market. Among the five major antique markets, Taihang Tower alone is crowded with people early in the morning, comparable to a scenic spot.

It would be nice to have an antique market in other cities, but it’s also so crowded that almost no one cares about it.

Jiangcheng is an ancient city, and its current industry characteristics have been formed through years of development.

Zhao Qiming: "Yes, as you know in the antiques industry, there are too many fakes circulating among the people. Nine and a half out of ten are fakes. Therefore, disputes often occur and many people choose to call the police."

"Especially the police station near the antique market, there is no idle time all day long."

Chen Yi nodded slightly and said: "In this industry, selling fakes is not called fraud, right?"

Zhao Qiming: "How should I put it? That's the unspoken rule of the antique business, the default rule. If you buy a real one, you'll make a profit. If you buy a fake one, you'll be unlucky. If you call the police, you won't be able to hang out in this circle in the future." Everyone knows it.”

Chen Yi: "Having said that, now everyone's concept of the rule of law is getting stronger and stronger. Even if there is an unspoken rule for antiques, goods that do not match the description can be returned. Don't you have targeted reforms? At least it can reduce the police rate."

Zhao Qiming said: "After the reform, the stall owners have learned how to speak. They used to directly tell buyers that the things in their hands are from the Tang Dynasty, but now they may be from the Tang Dynasty."

Chen Yi laughed out loud: "Sure enough, there are always more solutions than difficulties."

Maybe it was the Tang Dynasty, which did not meet the standards for fraud and was not likely to cause disputes.

The boss said it might be from the Tang Dynasty, which means that it might not be from the Tang Dynasty. He’s not lying. It’s up to you to decide whether it’s the Tang Dynasty or not. Anyway, I’ll just sell it for the money. What if it’s really the Tang Dynasty?

The addition of two words has no impact on the entire industry, but it has helped the police a lot and reduced the number of calls to the police.

The boss said it was possible, but who do you have to blame?

After seeing it, I can only blame myself for not being good at studying.

Zhao Qiming also laughed: "The industry is like this, and we can't set too strict rules when it comes to people's livelihood. Many tourists from across the country come to Jiangcheng, and one of their purposes is to visit the antique market. Even if they don't understand, they can spend a small amount of money to buy something. It’s a worthwhile trip, just buy a modern handicraft.”

Chen Yi hummed: "Last time I was busy investigating the case and didn't take a good stroll, but this time I'm free."

Zhao Qiming: "I will accompany Captain Chen."

Chen Yi: "No, you should be busy with your business. By the way, how many fraud gangs have been eliminated in recent years?"

Zhao Qiming: "About a dozen. These people deliberately set up traps to defraud money. They are fundamentally different from antique market stall owners. They are repeatedly banned. There is no way. There is no shortage of people in Jiangcheng who are willing to be deceived. Many people hope to get rich overnight. Startled."

Chen Yi thought of the National Treasure Gang online.

If there are two pieces in the world, then one in the museum and one in mine.

If there is only one in the world, then the one in the museum is fake.

Anyway, no matter what, what I have in my hand must be real.

The behavior of self-deception is just not wanting to believe that the dream of getting rich is broken. In this regard, older people are especially obvious and lack reason.

"Complete all the files tomorrow and let me take a look." Chen Yidao.

Zhao Qiming nodded: "Okay."

Chen Yi: "This investigation in Jiangcheng will be carried out in each branch and police station. You have to arrange special personnel to carry out random inspections and guidance at each level. All the work must eventually be shown in the research report, so it must be careful."

Judging from Jiangcheng's data, big cases are rare and small cases continue, especially ordinary disputes. This requires the police station and even the branch to have relatively stronger business capabilities.

Chen Yi had already made a comprehensive analysis before coming. This was the main task of the research team in Jiangcheng.

There are many trivial matters and no cases to investigate.

It was treated as a trip at public expense, but it was a pity that Fang Shuyu was not brought with him.

"Understood." When talking about work, Zhao Qiming became a little serious and sobered up a lot.

After the dinner, everyone said goodbye and the research team returned to the hotel.

Chen Yi and Fang Shuyu talked on the phone for a while. It was still early and they had nothing to do. He took the initiative to call Li Antai to inquire about the progress of the investigation into Gou Qiwen's murder case.

After listening carefully to Li Antai's words, Chen Yi said: "The motive and conditions for committing the crime are there. It seems that it is him."

Li Antai: "It must be him. He revealed his secret during the interrogation, but he was very tough and has not let go yet."

Chen Yi: "Normally, you have no direct clues or evidence."

Li Antai: "Team Chen, do you have any suggestions?"

Asking the leader what to do is actually an act of weakness, indirectly telling the other party that his investigation skills are not good. But since the other party took the initiative to call, Li Antai certainly would not miss the opportunity and just asked casually.

When he was at the scene during the day, Li Antai personally experienced Chen Yi's meticulous and flexible thinking ability, which was indeed better than his own. No wonder he was promoted so quickly.

Chen Yi: "Try material exchange. Let the people in the bureau comprehensively test the substances on the stool and compare them with the uppers of Gou Junyong's shoes. Judging from the situation at the crime scene, Gou Junyong should be standing sideways in front of Gou Qiwen, raising his feet." Kicked the stool over with his shoe."

"Don't he have a picking garden and a breeding farm? Maybe he can find unique substances."

Li Antai: "Okay, I'll start doing this right away."

Chen Yi: "If you pursue efficiency and accuracy, I suggest you send it directly to the provincial department. Then I will make a call and let the physical evidence center handle it first."

Now is the era of science and technology. Of course, the machines of the provincial departments must be more sophisticated than those of the bureaus. Coupled with the differences in the capabilities of the inspection personnel, the final results will definitely be different and the speed will be faster.

Li Antai was delighted: "Thank you so much, Team Chen!"

The bonus points for homicide performance are very high. They are assessed in any company or unit, and the police are certainly no exception.

Not only are there assessments, but there are also rankings. Being able to quickly detect a murder case is very important to the Chengnan Branch.

Chen Yi: "You don't have to be polite, I'll call you tomorrow."

Li Antai: "Okay, okay, then Captain Chen should take a rest early."

Chen Yi: "Yeah."

After hanging up the phone, Chen Yi lay on the bed and played with his mobile phone for a while, then turned off the light and fell asleep.

Maybe he was thinking about it day by day and dreaming about it at night. At night, he dreamed that he spent a few hundred yuan on a Yuan blue and white piece in the antique street. It was authenticated and sold for 100 million yuan.

When he woke up in the morning, Chen Yi's face looked a little strange. In his dream, he was a poor boy who experienced real overnight wealth.

"One hundred million?"

Chen Yi burst into laughter. To him, this was not a good plot at all, because he owned many, many billions.

Rich people will not read the works of God and luxury. There is too little room for sexual immorality.

The research team chose the hotel buffet for breakfast. During the meal, Chen Yi called Wei Jianfeng and asked the other party to inform the physical evidence center and provide the results as soon as possible after receiving the physical evidence from the Chengnan Branch.

Wei Jianfeng is not only the captain of the Provincial Department's Criminal Investigation Team, but also the director of the Provincial Department's Physical Evidence Identification Research Center. This is a relatively high-level position. There is a high chance that the other party will be promoted to the deputy department in charge in the future.

"The murder in Ximei Village?" Wei Jianfeng was surprised, "How do you know that there was a murder in Ximei Village? I don't even know."

Chen Yi smiled and said: "Ximei Village is going to be demolished. The developer is the Chen Group. I went to watch the conflict between the villagers and the developer before. My friend called me and told me."

There is no need to hide this kind of thing, otherwise it will easily cause unnecessary misunderstandings. Just say it openly.

Wei Jianfeng exclaimed: "What a coincidence, okay, I will supervise it after the physical evidence arrives. A murder happened just at the juncture of demolition. It is not good to delay for too long. You are already in Jiangcheng, right?"

Chen Yi: "Yes, I'm in Jiangcheng. I just had a meal with my colleagues from the Jiangcheng City Bureau and will start work tomorrow."

Now that they were on the phone, Wei Jianfeng asked a few more questions: "What is the direction of your work?"

Chen Yi: "Jiangcheng has a high police response rate and constant small cases. Let's focus on improving the police station's business capabilities. This matter has to fall on the Jiangcheng City Bureau, and our research team cannot be of much help."

Wei Jianfeng: "Jiangcheng is a tourist city. There is no problem with the direction you choose, but the investigation of Jiangcheng City Bureau cannot be ignored. You and Zhao Qiming are old friends, so don't be affected by this."

Chen Yi did not say anything about the situation, and said: "It must be false to say there is no impact. Don't worry, Captain Wei, I know it."

Wei Jianfeng smiled: "Okay, you figure it out."

He still trusts Chen Yi very much.

After hanging up the phone, the research team came to Jiangcheng City Bureau.

In the conference room, Zhao Qiming had sorted out the files and placed them in front of Chen Yi.

Checking the files was not just a formality. Chen Yi wanted to go through the files to see if he could find any unusual details.

Today, the research team will stay at the city bureau.

…

Afternoon, Yangcheng.

Wei Jianfeng said that the physical evidence center was extremely efficient. Li Antai went to the provincial department in person to get the test results.

The above content is relatively professional, and Li Antai doesn't understand it very well. He needs to go back and ask, or... he can just ask here.

The organic matter content is 25.5%, the phosphorus content is 1.54%, the potassium content is 0.85%, and the nitrogen content is 1.63%...

What does this mean?

Looking at his busy colleagues in the provincial department, Li Antai said politely: "Brother, what substances do these elemental contents represent?"

The appraiser had a good attitude and answered all questions: "Chicken manure."

Li Antai's eyes narrowed: "Chicken manure?"

Appraiser: "Yes, chickens are rectal animals, so the organic matter in the feed cannot be completely digested and will be excreted directly. Therefore, chicken manure will contain a large amount of organic matter, up to more than 20%."

Li Antai quickly looked back at the test report, and found that the substance was found in the upper middle of the stool legs and on Gou Junyong's shoe uppers.

Ximei Village is a village in the city. With the development of the city, every household no longer raises chickens, ducks and geese. At most, they can see cats and dogs.

There is only one small chicken farm in the whole village, and it belongs to Gou Junyong.

Is this irrefutable evidence? Not necessarily, you also need to rule out the possibility of other people entering and leaving the chicken farm.

However, this clue alone was enough to pry Gou Junyong's mouth open.

"This is what Captain Chen calls material exchange. It gives a decisive direction in an understatement. Although we can think of it, we won't do it that day."

Li Antai closed the report. He now understood why the other party was able to solve so many major cases. His main skill was precision and speed, and he could even predict the outcome.

Even if this is the case on the sidelines, if he is solely responsible for the investigation, the strength he will exert will be even more amazing.
