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

The next morning, Chen Yi and others left Yangcheng.

There was no big scene, just a business car, driven by Qin Fei.

This time it is a survey, not an inspector, but the Suicheng police must understand that there is not much difference between the two. If the research team encounters any serious mistakes, Chen Yi, as the team leader, is very likely to turn the survey into an inspector on the spot. .

Let’s not talk about where Chen Yi’s position is. Even if it can’t be handled, it can be done with just one phone call.

Does the provincial department listen to Suicheng or Chen Yi? It's obvious.

Therefore, if the Suicheng police say they are not nervous, that is a lie.

After receiving the news from the provincial department, the municipal bureau immediately launched security patrols throughout the city, stepped up the prevention and control of illegal crimes, and tried its best to leave a good impression on the research team to avoid negative comments from Chen Yi after returning to the provincial department.

Chen Yi naturally understood this after experiencing the Jiaocheng case, so he asked Wei Jianfeng yesterday whether he had informed the cities of the investigation.

Now that we have been informed, many things will be meaningless and there is no need to waste time.

Three hours later, the vehicle got off the highway and reached the boundary of Suicheng.

As imagined, Suicheng is indeed a vast city with few people and a wide view, with few buildings blocking it.

With low housing prices and low consumption, it might be a good place for retirement.

However, it is a third-tier city after all. "Suitable for elderly care" has a derogatory connotation, indicating that economic development is slow or even retrograde, and the pace of life is very slow.

Chen Yi is looking at Zheng Congliang's information. He is not preparing to investigate, but just getting to know him in advance.

Zheng Congliang, the captain of the Criminal Investigation Detachment of Suicheng City Bureau and a second-level police inspector, is almost fifty years old and close to the age of leaving his post. Generally, detachment captains are over thirty-five and under fifty.

From a civilian police officer to a criminal police officer to a detachment leader, Zheng Congliang's resume is pretty good, but reaching this position at the age of forty is more a matter of hard work and qualifications.

If you have the ability, it's okay.

To put it bluntly, among short people, look for relatively tall people.

"Team Chen, this Zheng Congliang is twenty years older than you." It was Fu Guoyong who spoke.

Nowadays, the leadership team is getting younger. The detachment leaders who are almost 50 years old have basically said goodbye to promotion. This will be the case in this life.

This is from the perspective of the provincial department, and from the perspective of ordinary people, the captain of a city's detachment... is a very big official.

Chen Yi: "I have been a police officer for more than 20 years. I have participated in and led a team to solve 1,600 criminal cases. I have recovered long-lost children for 50 families. I have uncovered five fraud gangs in seven cities. He has been awarded the second-class personal merit four times, the third-class merit six times, and the personal commendation nine times."

"He is a very experienced veteran detective and deserves the respect of all of us. Do you understand what I mean?"

It is true that the crime detection rate in Suicheng is low, but Zheng Congliang's contribution cannot be denied.

Doesn't he want to solve the case? Doesn't he want to catch the suspect? Doesn’t he want to give justice to the victims?

He also thought about it, but he just had more ambition than strength.

Several people: "Yes, Captain Chen."

There is nothing particularly outstanding about Zheng Congliang, but more than 90% of the police across the country are people like him. They are dedicated and perseverant, do their jobs seriously, strive to perform their duties, and work tirelessly to combat illegal crimes.

The probability of major cases happening is very small, and there are not that many complex cases. Every city needs Zheng Congliang, and the more policemen like this, the better.

Vehicles drive into the city at very fast speeds. There is no traffic jam in Suicheng. Compared with the congested Yangcheng, this place is simply a paradise.

As we approached the Municipal Bureau, we could already see a lot of people waiting. As the distance between the two parties got closer, Zheng Congliang's figure appeared in the crowd. Standing in front were the leaders of the Municipal Bureau.

The vehicle stopped at the door and everyone got out of the car.

"Captain Chen, welcome."

Two middle-aged men came forward to shake hands, one was the deputy bureau in charge of criminal investigation and the other was the chief bureau.

When the provincial investigation team comes to Suicheng, the real boss will of course show up. As for the follow-up matters, he will not care about it. The investigation team is targeting criminal investigation this time, and someone will be responsible for following up.

After chatting for a while, everyone entered the city bureau. It was already noon, and a meal had been arranged. Chen Yi proposed that he wanted to try the food in the bureau, so everyone went to the canteen.

After the meal, there was a meeting. Chen Yi sat in the first seat, followed by deputy director Wang Shengrong, detachment leader Zheng Congliang and others.

One of the purposes of the research work is to seek truth from facts and implement the behavior of deceiving superiors and concealing subordinates from falsely reporting results. The materials have been prepared and sent to Chen Yi.

Old documents cannot be faked.

"You guys go on, I'll take a look first."

Chen Yi flipped through the documents and signaled the spokesperson of the Suicheng detachment to speak. This was a necessary procedure.

Wang Shengrong gestured to Zheng Congliang, and the latter began to read the manuscript.

"Hello colleagues from the research team, hello Team Chen, I am Zheng Congliang, captain of the Criminal Investigation Detachment of Suicheng City Bureau. It is my honor to discuss issues related to criminal investigation work with you through the survey today. Now I will focus on the following aspects."

…

"First of all, I want to talk about the importance of criminal investigation..."

…

"Secondly, I would like to highlight the challenges facing criminal investigation at this stage..."

…

"At the same time, I think the construction of criminal investigation forces is very important, especially for us in Suicheng..."

…

"Finally, I would like to make some suggestions, and I hope the provincial department can consider them..."

The manuscript was very long, and Chen Yi listened slowly and attentively. Although it was a programmed speech, the content was not programmed. It was obvious that Zheng Congliang had prepared carefully for this.

"thank you all."

Applause rang out, and Chen Yi put down the document and looked at Zheng Congliang.

A very calm man, his eyes are deep and bright as if they have experienced countless wind and rain. He is nearly fifty years old, and the years have left ravines on his face.

Zheng Congliang is not a tall man, but he has a sense of strength all over his body.

The police uniform he was wearing was already a bit old.

"Zheng Zhi has achieved outstanding results in his work over the years and has made great contributions to social security in Suicheng. He is a role model and role model for all our police officers. On behalf of the provincial department and the Criminal Investigation Corps, I would like to pay tribute to Zheng Zhi. Thank you for your hard work."

Everyone looked at Zheng Congliang, who was obviously stunned for a moment. They didn't expect that this too young provincial police supervisor would praise himself first and express his affirmation to him.

Of course he had heard of Chen Yi. He was labeled as a master of criminal investigation and a talented person. Several serial murder cases that were extremely difficult to solve were solved by his hands and the suspects were brought to justice.

Two months ago, he almost died trying to save others.

As a rising star, Zheng Congliang himself began to lament that the world is now dominated by young people.

He also knew that there must be someone behind Chen Yi, otherwise he would not have been promoted so quickly, but his ability to solve those cases was admirable.

"Thank you, Captain Chen. Thank you to the provincial department. This is what I should do."

Zheng Congliang kept his posture very low and spoke modestly.

A person who is almost fifty years old treats a young man with respect, and the youthfulness of the leadership team is very intuitive.

Regardless of position, Chen Yi is two levels higher than him in terms of police rank.

Chen Yi closed the documents in front of him and said: "Let's put the other things aside for now, Zheng Zhi. Bring over the files and detailed investigation report of the 622 poisoning case last year."

622 poisoning case?

The Suicheng Criminal Investigation Detachment looked at each other, which was not surprising. The provincial department said that the investigation team would guide the investigation of the backlog of cases, and they had already received the news.

The 622 poisoning case occurred recently and had the greatest impact. After all, the victim died in public in public.

This case attracted widespread attention from all walks of life in Suicheng last year. After the incident, there were a lot of messy videos on the Internet, including various official accounts of the Suicheng police in the comment area, which gave the city bureau a lot of attention. pressure.

Unfortunately, it has not been solved yet.

"Okay, Captain Chen, wait a minute." Zheng Congliang turned to look at someone, "Xiao Li, bring everything as requested by Captain Chen, including the video files."

The video file, of course, refers to the surveillance video. The victim was poisoned on the bus. The video inside the bus is one of the most important clues and has been watched countless times by investigators.

"Yes, Captain Zheng." The police officer who was called Xiao Li stood up and left quickly.

Wang Shengrong said: "Team Chen, do you want to focus on investigating this case?"

Chen Yi: "Is the team busy lately?"

Wang Shengrong looked at Zheng Congliang, who said: "The investigation brigade has several new cases that are being followed up. If we focus on investigating 622, we need to temporarily abandon one of them, or transfer someone from the branch."

"A new case..." Chen Yi thought for a moment and said, "Don't miss the golden period, take care of the new case first."

The detachments and branch teams are very busy, and it is the same in every city. It is impossible to focus on one case all the time.

It often happens that old cases are unsolved and new ones arise. Anyone who is a police officer knows that unless a new case can be solved in a short time, this is very difficult to do.

Even Chen Yi himself had times when he was stretched thin during his tenure as detachment leader and had to make decisions about where to focus.

Wang Shengrong: "What does Captain Chen mean?"

Chen Yi: "Including Zheng Zhi, plus two front-line police officers who are very familiar with the case, preferably those responsible for comprehensive interviews, we will go over the case again."

Looking into old cases does not require too many manpower, and you can advance the case by finding the overlooked points.

Zheng Congliang had no objection and turned to Wang Shengrong.

Wang Shengrong saw that Chen Yi was a vigorous and resolute person who didn't like to talk nonsense or follow red tape, so he readily agreed: "Okay, we will do whatever Captain Chen says and cooperate fully. Then... I won't disturb your work?"

Chen Yi did not chase away guests, but he was very discerning.

Without participating in the frontline investigation of the case, there is no use for him to stay.

Chen Yi nodded: "Wang Bureau, let's talk back."

Wang Shengrong left the conference room.

The dossier was quickly brought over and placed in front of Chen Yi. Chen Yi turned over the first page and pushed the rest to Qin Fei and the others. Everyone looked at it and understood the whole dossier as quickly as possible.

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

Zheng Congliang waved his hand and asked the investigation team below to work on the case, leaving behind two police officers who had continued to follow up on the case, including Xiao Li.

He is no longer young, he looks to be in his thirties.

As time went by, Chen Yi and others learned more and more about the 622 case. The investigation area of ​​this case was very wide, covering almost the entire Suicheng University, and also included relatives of the victim Gao Xiaofei.

As long as they are relevant, they are all within the scope of investigation.

The direction of this case is actually very simple. Who put poison in the vitamins Gao Xiaofei carried with him.

There are actually not many people who can do this, so everyone close to Gao Xiaofei, regardless of age or sex, is a key target of investigation.

"What a pitiful life experience."

Zhuge Cong whispered.

Three members of Gao Xiaofei's family, including his younger brother, were killed in a fire nine years ago. The house was completely burned, and Gao Xiaofei was almost burned to death.

At that time, she was in the second grade of junior high school.

Over the years, it was her only grandmother who raised her and sent her to school.

However, when Gao Xiaofei was about to graduate in her senior year, something like this happened.

It is conceivable that Gao Xiaofei's grandma must be very depressed and doesn't know what is going on now. It is very dangerous for older people to experience extreme grief again.

I lost my son, daughter-in-law and grandson nine years ago, and my granddaughter last year. I have become completely alone, which is difficult for ordinary people to accept.

Chen Yi closed the file. According to the investigation by the Suicheng Criminal Investigation Detachment, there were four people suspected in this case.

The first one is Gao Xiaofei's college roommate, and there is a bit of a conflict between the two.

The second one is Gao Xiaofei's cousin. After interviews, it was determined that the relationship between the two was not good. According to relatives, they often quarreled.

The third one is Gao Xiaofei's boyfriend, and it is customary to check the partner first.

The fourth one is a classmate who has been chasing Gao Xiaofei for two years. There is a possibility of love turning into hatred.

These four people found no evidence during the investigation, not even directional clues, and no abnormalities were found during the questioning. If the murderer is really among the four, then his psychological quality is still very strong.

Trivalent arsenic is strictly controlled by the state. The criminal investigation detachment also investigated pharmacies in the city where the ingredient can be purchased, and no one or suspicious person was found to be socializing with Gao Xiaofei.

Having said that, although trivalent arsenic (arsenic) is actually difficult to buy, it does not mean that it cannot be purchased. If you want to find it, you should be able to find it in relatively backward rural areas.

Poison control cannot be comprehensive, otherwise there would not be so many people committing suicide by taking drugs.

As long as it exists, you can definitely get it, unless it is that rare element.

"Look at the surveillance." Chen Yi said.

The big screen lights up, and the real-time monitoring inside the bus appears in front of everyone.

It was the weekend, so there were quite a lot of people in the car. Gao Xiaofei's position happened to be under surveillance, so there was no blind spot.

She sat by the window, wearing long sleeves in the summer, listening to music and looking at the busy traffic outside.

The reason why she wears long sleeves is because Gao Xiaofei has burns on her arms, which have been scarred for nine years.

After the bus drove for twenty minutes, Gao Xiaofei naturally took out a bottle of vitamin C from her bag, poured two pills into her mouth, and moved skillfully.

She eats it often.

Three minutes later, Gao Xiaofei reacted, covering her stomach and head with a painful expression, and then fell to the ground uncontrollably.

Abdominal pain, dizziness, nausea, and general numbness are consistent with symptoms of trivalent arsenic poisoning.

The car fell into chaos. People around him rushed to check and called the emergency number. Until the ambulance arrived, Gao Xiaofei was sent off the bus and the scene stopped.

No one came close to Gao Xiaofei before he was poisoned, and the poison did come from the bottle of vitamins.

It was obvious that this was a deliberate murder and that the poison had been put into the bottle in advance.

After reading it, Chen Yi lowered his head and flipped through the file again and found a page about vitamins.

Why does Gao Xiaofei take vitamins? Because she had another poisoning experience, which was chronic iron poisoning.

One of the treatments for chronic iron poisoning is to take vitamin C.

Chronic iron poisoning cannot kill people. The cause of poisoning is usually overdose of iron supplements or long-term high-iron diet. The clinical reactions are skin pigmentation, hepatosplenomegaly, etc.

"Chronic iron poisoning..."

This is a doubtful point, and Chen Yi lists it as one of the key clues in his mind.

There is another very key figure, the fourth of the four suspects: Zhao Jianhui.

He chased Gao Xiaofei for two years, and finally she fell into the arms of others.

Before Gao Xiaofei got on the bus, she had a seafood buffet with Zhao Jianhui. He was the last acquaintance of Gao Xiaofei to see her.

It is precisely because of this that Zhao Jianhui was investigated the most times. In the end, he even strongly resisted the police, showed uncooperative behavior, and was forcibly summoned to the city bureau.

The interrogation yielded no results, and the cafeteria's surveillance revealed no unusual behavior.

This case has been put on hold until now.

Over the past year, the Suicheng Criminal Investigation Detachment has never given up on the investigation. Whenever new clues appear, they will pounce on them with all their strength.

Chen Yi knocked on the table out of habit, then took out a cigarette and lit it.

This case is indeed not easy to investigate, so it’s understandable that Zheng Congliang is helpless.

At this moment, everyone's eyes were on him.

After taking two puffs of cigarette, Chen Yi turned his head slightly and looked at Zhuge Cong and the other two people. He didn't know how good the talents in the provincial department were.

"Look at what I'm doing, tell me."

Cheng Hanjun looked at Zhuge Cong, and Zhuge Cong looked at Fu Guoyong. No one wanted to be the first to stand out.

Finally, the three of them turned their attention to Xia Lan.

Xia Lan was stunned for a moment and said speechlessly: "Don't you think too highly of me?"

She is Chen Yi's civilian assistant. She doesn't care about investigating the case. She can at most interject when an idea strikes her.

There is no prototype of the case, please do not take it personally.
