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

At the second meeting of the investigation team in Suicheng, Chen Yi became more serious. Wang Shengrong, the deputy director in charge of criminal investigation, also came. Compared with the first meeting when they first came to Suicheng, the atmosphere was a bit solemn.

The first is the 622 Poison Murder Case last year. Although the case has some twists and turns and is not easy to investigate, there are definitely traces to follow. The Suicheng Criminal Investigation Detachment has not solved the case for a year, and even the suspect Gao Huimei has not been identified. , need to carefully sum up experience and accept criticism.

Zheng Congliang remained silent, and he did not resist Chen Yi's accusation in his heart. The investigation team solved the cases that the Suicheng detachment had not solved within two days. This is a fact, and it illustrates the problem.

Of course, there is also the reason why the Suicheng detachment has gone through a lot of trial and error. Ninety percent of the clues and suspects have been investigated, and what the investigation team has to do is to find the remaining ten percent.

There is no mistake, but criminal investigation capabilities need to be improved. The focus is on the control and analysis of criminal psychology and suspicion of everything.

In some cases, investigation based on clues may not lead to results. In this case, reverse investigation is needed. First guess the results and then verify them. You may get unexpected gains.

To do this requires a lot of experience and bold imagination.

Reality is always more ridiculous than imagination, so in theory you can't overthink it. Criminal investigation is a process of trial and error.

The next thing is the last one in the detection rate. The data quantification will definitely lead to the last one. It is unavoidable. This may not be a problem of the Suicheng Criminal Investigation Detachment, but the last one is the last one. Chen Yi investigated on behalf of the provincial department. If you need to beat, you should beat.

Finally, it is the future of the Suicheng Criminal Investigation Detachment.

"Reform, innovate, summarize more, communicate more, boldly recruit new people, and tell them not to be afraid of making mistakes."

Chen Yi's voice echoed in the conference room, and everyone lowered their heads to record.

Maybe he was overthinking it. Zheng Congliang felt that Chen Yi was asking whether he should take a back seat.

I praised myself a lot in the last meeting, but this time everything has changed.

Who makes Suicheng the last one? He is confident that he has done a good job. There is no way, the result is not fake.

The crime rate is not the highest, but the detection rate is the lowest. Anyone who investigates has to scold the person in charge of criminal investigation first. Chen Yi is being polite.

Wang Shengrong wanted to say something nice for Zheng Congliang, but after organizing it for a long time, he didn’t know where to start.

Qualifications? Which detachment leader has no qualifications?

ability? That detachment leader is not very capable.

Credit? Although the Chen Yi in front of him is young, he has experienced nine deaths. According to the news, the family members of the victims have knelt down for him. He has a great reputation. Talking about credit in front of him is a bit self-degrading.

Forget it, let's not talk about it. The research team is willing to make it clear, at least there will be no accountability.

"Bring the dossier."

Chen Yi's mouth went dry as he spoke. He drank a sip of water and waved to Zheng Congliang and the others.

Zheng Congliang quickly ordered his men to move the files.

Two years ago, there was a nationwide cleanup of the backlog of cases. It was initiated by the Criminal Investigation Bureau of the Imperial City Police Department and was labeled "Operation Spring and Autumn." It meant that during the six or seven months from spring to autumn, all unresolved cases were rectified.

The results were pretty good. More than 600 old cases were cleared, including 400 cases that were more than 20 years old. The longest unsolved case was 45 years old. The homicide detection rate soared to 99.8%. However, besides.

The provincial department’s order this time is to continue clearing up the backlog of cases. As the leader of the investigation team, Chen Yi must do his best.

From the backlog of cases, remove those who are wanted and on the run, remove those that cannot be investigated and obtain evidence, and except for ten categories, the rest must be studied.

What are the ten categories?

Intentional homicide, intentional injury causing serious injury, rape, robbery, kidnapping, drug trafficking, arson, explosion, placing dangerous substances, burglary.

Excluding drug trafficking cases, there are still nine categories.

As long as there are still backlogged cases in the nine categories, we need to try to deal with them. The results cannot be guaranteed, so just try your best.

The police officer brought the file and placed it in front of Chen Yi, who distributed it to Zhuge Cong and others and studied it carefully.

The conference room fell silent except for the sound of turning pages.

There was no murder case in the file in Chen Yi's hand. He noticed a theft case fifteen years ago. What was lost was gold. The location was a gold shop and it was worth millions.

A million dollars fifteen years ago is not the same concept as it is now. At that time, even the housing prices in Imperial City were less than ten thousand.

The files show that the owner of the gold store is named Fan Tianchi and the manager of the gold store is named Gui Dacheng. After a long period of investigation, the case has not found the perpetrators, and it has become a backlog of cases.

The gold store is under surveillance, and it is very clear and there are no blind spots. Apart from the masked figures and footprints of the two male suspects left at the scene, there are no other clues. The suspects wore gloves when committing the crime.

The door to the gold shop was pried open.

However, all the gold was in the safe. Surveillance showed that after the two suspects broke into the gold store, they opened the safe in a short time and took away all the gold inside.

The surveillance camera was able to capture the safe, but the suspect's back blocked his movements, so we didn't know how he opened it.

Judging from the time, it is most likely by entering a password.

It's impossible to pick a lock by listening to it, but it was possible in the early days.

Modern safety locks are different from the early ones. The early old-fashioned safety locks rely on the correct combination of the rotating core and the gap to open and close the lock. Therefore, if the lock position is correct during the unlocking process, the ratchet valve will lock the gap and make a specific sound.

The listening unlocking shown in the TV series uses this feature to rotate and listen carefully multiple times to determine how far the lock has been opened, and finally successfully open it.

This is not possible now. Today's safety locks are basically silent and have a limited number of openings. They do not give the unlocker a chance to make mistakes. If the lock is opened more than once, the alarm will automatically sound.

This case was investigated by Wang Shengrong at that time, and the suspicion was focused on the insiders of the gold store. However, after investigation, there was no time for the crime to be committed. Later, it was extended to the insiders colluding with family members or outsiders to commit the crime, but there was still no result.

The next step is to sell the stolen goods. The suspect must realize the stolen gold. If the suspect was not found based on this, naturally there will be no results.

Including the possibility that the store manager Gui Dacheng was cheating and stealing, has also been ruled out.

This is rather contradictory.

The suspect most likely knows the password. The person who knows the password must be an insider, but the insiders are ruled out as suspects.

Very strange.

Either it was missed, or there are other possibilities in the case that have not been discovered.

Since it is a backlog of cases, it must be against common sense, but after so many years, the possibility of finding the thief is very low.

There is one person worth noting in the file, and that is the boss Fan Tianchi. This man was a famous figure in Suicheng at that time. He started in the gray edge industry and was a frequent visitor to the police "visits". Later, his business grew and grew, and he owned several financial institutions in Suicheng. shops and entertainment venues, as well as hotels and large supermarkets, and has since become a major taxpayer in Suicheng.

"Fan Tianchi, the name of the company is Tianchi..." Chen Yi was curious about this person and turned to look at Wang Shengrong, "Wang Ju, is this Fan Tianchi the top entrepreneur in Suicheng?"

Wang Shengrong nodded: "Yes, that was the case before but not now. I heard that there was a dispute within the company, and he lost completely and retired to retire."

Chen Yi: "A dispute between the younger generations?"

Wang Shengrong didn't know much about this: "No, the boss of Tianchi Company is not named Fan now, but Li."

Chen Yi exclaimed: "Is that an uprising by his subordinates?"

Wang Shengrong: "I guess so."

Chen Yi smiled: "It's quite impressive. You can take over the company if you are not a relative, but you can't do it without some tricks."

Wang Shengrong glanced at the file in front of Chen Yi and said, "Is Captain Chen looking at the gold theft case fifteen years ago?"

Chen Yi: "Yes."

Wang Shengrong recalled: "I investigated that case, and it was very strange. The suspect definitely knew the password. Later, we watched the employees inside the gold store for a long time, but we did not find any behavior of selling the stolen goods. Just last year, I asked Lao Zheng to investigate by the way. After checking, nothing suspicious was found.”

"If it was really done by an insider, it would be impossible for it not to be sold after more than ten years, right? If it were sold, wouldn't it cost a penny?"

Chen Yi: "You haven't left Suicheng?"

Wang Shengrong: "No, they are all locals and they left quietly without being noticed."

Chen Yi: "It's really strange."

Last year, we were still verifying the suspects in this case, which shows that Deputy Director Wang Shengrong is still relatively qualified and has not given up.

Wang Shengrong: "By the way, I just mentioned that the boss of Tianchi Company is surnamed Li. There is a case related to the Li family. Eight years ago, Tianchi's boss Li Gong was killed. The crime scene was in the hotel bathroom, and the murderer was not found."

Um?

Chen Yi was slightly stunned.

On the other side, after hearing Wang Shengrong's words, Zhuge Cong handed over the file in his hand: "Team Chen, this is the detailed file on the murder case of Li Gong."

Chen Yi took it and turned to the first page.

After a rough look, he found a problem. The manager of the gold store was later changed to Li Gong.

"Wang Bureau, after the gold store was stolen, the store manager became Li Gong, and the original Gui Dacheng was replaced. Have you ever considered that the theft may be related to the vicious competition within Tianchi?" Chen Yi pointed out the problem directly.

Wang Shengrong: "Well, I haven't thought about this. Gui Dacheng took the blame for the theft in the gold store and resigned. It's normal for Fan Tianchi to replace the store manager."

Chen Yi nodded: "It makes sense, but everything that should be investigated has been investigated. The truth may be outside conventional thinking. For example, the suspect is an outsider and no one knows him. The password was told to the suspect by Li Gong, and the purpose is to let Jin Shop theft achieves its intended purpose.”

Wang Shengrong pondered, the 622 murder case had just been solved, and he had no doubts about the ability of the investigation team, especially Chen Yi.

Internal struggle? That’s why I couldn’t find it.

Chen Yi did not discuss further and looked at Zhuge Cong and the others: "How many more murders are there?"

Zhuge Cong: "In addition to the murder of Li Gong, there are two more."

Seeing this, Wang Shengrong and Zheng Congliang sighed secretly, feeling somewhat embarrassed. Today, with the murder detection rate rising rapidly, it is not unfair for Suicheng to be ranked last.

Chen Yi: "Time, gender, occupation, special experience."

Zhuge Cong: "Fifteen years ago, five years ago, they were all men, all unemployed, and all had criminal records."

Chen Yi rubbed his forehead. It was really hard to be the leader of this research team. Wei Jianfeng found a "good job" for himself.

Wang Shengrong quickly handed over a cigarette. Maybe smoking a cigarette would extinguish the fire...
