After working for so many years, Han Bo has never been interviewed by a reporter alone.

There are many times when I enter the camera, and every time I am a "passerby A". There are occasionally one or two close-ups, and basically no lines. I think about it carefully. When I only acted as the protagonist once. When Yushan "cracked down", I went to the county TV station to read a joint announcement urging criminals to surrender. It can be said that I have no experience in dealing with the media.

Sitting with the reporter, no matter what you say, even if you don’t say a word, you are accepting an interview. Without an attitude, it is an attitude.

Li Xiaolei has rich experience in dealing with the media and has discovered that Yao Jie has turned on the "interview mode", sitting aside and smiling without saying a word, and being optimistic.

Han Bo didn't understand why, to be precise, Xin Siquan didn't care about these things at the "poisonous gas murder case" that Xinyang City was trying to solve, and he couldn't think of this floor. While eating, he answered Yao Jie's questions. Seeing that it was getting late, he went downstairs with the three of them and drove to the Public Security Bureau.

The troops were divided into two groups, and Ge Zhengjian asked Li Xiaolei to the dormitory of the agency, while he took Yao Jie to the office of the Criminal Investigation Corps.

The reason why I brought her here to introduce her to the political commissar of the corps was not that she was very attentive when she saw a beautiful girl, but that as the deputy secretary of the Yushan County Party Committee, she had the responsibility and obligation to contribute to the economic development of Yushan. However, Yushan wanted to develop the tourism industry, but she really needed the media to help promote it.

But things didn't go as expected. I walked into the office building where the Criminal Investigation Corps was located. I didn't see any stories worthy of publicity, and there were several people making a big fuss in the building.

Political Commissar Guo of the Corps seemed to be receiving an interview, and it seems that this is not the first time these people have been making trouble.

The police officers from the General Corps Department worked with Political Commissar Guo, but the effect was obviously not very good. The visitors were excited and stared at them with beards and stares flying. Although they couldn't understand what they were saying, they could guess the meaning, but it was nothing more than the public security organs did not enforce the law impartially.

It's hard to say and persuade you no matter how hard you say it, it doesn't work.

Political Commissar Guo was anxious and said, "I can't take care of your affairs. I don't care. Whoever I want to find, go and sue if I want to sue." He walked up the stairs with a stern face. Several people wanted to chase him, but the police stopped the stairs and refused to go up.

Han Bo has seen many such scenes.

When working in Nangang, I had concentrated on cleaning up a number of controversial cases involving visits. Every time I went to the provincial department for a meeting or a business, whether in Jiangxi Province or transferred to Guizhou Province, or even when I went to the Ministry of Public Security, I could see many visitors gathered at the door of the letter and visit reception room, and some exaggerated even banners.

There are many reasons for this. After all, China is so big and a province is not small, so it is inevitable that one or another will happen.

Many people think that visiting can solve the problem, so they go up and go up. It may be a case at the county level, but it seems to be a lot at the provincial level.

Now there is a more important job, and even if there is no more important job, you cannot be more uncontrollable. Han Bo presented his ID, and all the comrades in the Comprehensive Department knew him. They immediately made a way to let him and Yao Jie go upstairs.

The Public Security Department is the leading organ of the public security system in the province, but there are not many police officers in the department. The particularity of public security work determines that the police force must be reduced. Therefore, the unit level of the Criminal Investigation Corps is quite high, but the institutions are very small. There are only comprehensive departments, major cases, organized crime investigation departments, drug control and drug rehabilitation departments and a criminal science and technology research and management center (physical evidence identification center).

The Criminal Technology Center is located outside, and there are only more than 30 police officers working in the provincial department.

Knocking at the door and walking into the political commissar's office. Political Commissar Guo, who had just calmed down, was very enthusiastic. He learned that Yao Jie was a reporter from the provincial newspaper. He was afraid that she would take preconceptions and complain about the road, and talked about what had just happened downstairs.

Just send the person here, Han Bo greeted him and went to the opposite office to find Team Du.

"Han Bo, it's here! Sit, do you drink water?"

"Co-Co-President Du, don't be polite, I'm not thirsty."

I thought he would stay in the task force, but I didn't expect to come to the corps early in the morning. Han Bo's appearance here surprised Du Zhigang, or looked at him with admiration.

No matter which unit a comrade is transferred to, the first thing he must do is to be able to enter the role and be able to put his position in the right position.

The provincial department only arranged a person to guide the investigation of the murder case in the jurisdiction of Shiyan Branch, but did not supervise it. He went to the scene to see it, listen to the report, and give some opinions. If he stayed in the task force, the grassroots comrades would think and see what they thought.

It is worth mentioning that Xinyang Municipal Bureau is different from other municipal bureaus or regional public security bureaus.

As the public security bureau of the provincial capital city, the investigation force is the strongest in the province. There are many experienced old criminal police officers, and their criminal science and technology equipment and level are also the best. In the investigation of specific cases, the corps really has no good guidance. On the contrary, when major cases occur in other cities or regions, criminal police and criminal technicians will be drawn from the Xinyang Municipal Bureau to assist.

Didn't say it clearly yesterday, it can be considered a test.

Unexpectedly, the young man had a high level of professionalism and would also become an official.

Thinking about it, Han Bo's current identity is still a member of the Standing Committee of Yushan County Party Committee, deputy secretary, and secretary of the Political and Legal Affairs Committee. Du Zhigang suddenly found that his previous thoughts were a bit funny, and he thought to himself that he was an official, so why didn't he understand these things?

Since they are here, of course they have to talk about work.

Du Zhigang put the materials in his hand aside and asked with his fists: "Comrade Han Bo, are you sure the cause of death of the deceased in Shi Yan's case? Is it a killing or food poisoning?"

When the notice was issued yesterday, whether the criminal case was not yet determined.

The more Han Bo thought about it, the more he became puzzled. He thought this matter was a bit ridiculous and a little ethereal. Secretary Lin obviously regarded this case as an excuse to urge him to come here early. How many public security systems in the province can enjoy this treatment?

"Council Du, this case is very strange. The test results of the deceased's vomit obviously do not contain toxic drugs. The four deceased did not go out at the same time on the day of the incident. The elderly among the four deceased have been staying at home, and the possibility of highly toxic chemicals leaking can be basically ruled out. All signs indicate that it was homicide."

"Not in the vomit, is it in the stomach?"

"They died in the hospital after failed rescue efforts. The medical staff took first aid measures and washed their stomachs. They vomited, and they probably had nothing in their stomachs. However, the Shiyan Branch responded in time, not only extracting the vomit from the deceased's home, but also extracting the vomit from the hospital, and all of them were not detected."

Du Zhigang reacted and stared at him and asked, "It's not something that is consumed by the digestive tract, it can only be injection or inhalation?"

Han Bo nodded and confirmed: "The forensic doctor carefully examined the corpse table. Apart from the injection pinhole during first aid, the second pinhole could not be found. If one person dies, there may be some misses. The key is that four people die and the whole family will die."

"Inhaling toxic gases!"

"The Second Hospital of the City has tested their blood and urine and found that the blood has high cyanide ions and the clinical symptoms are consistent with the characteristics of cyanide-hydrogen poisoning. Medical staff even smelled bitter almonds from the breath they exhaled."

Poisoning is very serious, and using poison gas to commit crimes is even more serious!

Such cases have never happened in the province in the past decade, and it is estimated that they are extremely rare in the whole country.

Thinking of the case of Japanese cults creating poison gas on the subway, Du Zhigang felt a little frowning and asked, "Comrade Han Bo, what do you think of this case?"

Han Bo thought about it and said helplessly: "There are many cases of cyano-hydrogen poisoning, mainly safety accidents in chemical companies. Chemical hospitals and occupational disease hospitals treat more than a dozen or even dozens of cases every year. Cases of cyano-hydrogen poisoning are rare because it is a highly toxic chemical that is difficult for ordinary people to come into contact with, and it is easy to evaporate, and it is extremely dangerous. The murderer cannot wear a gas mask to poison it."

"Coincidence, accident?"

"When I came back last night, the leaders of Xinyang Municipal Bureau instructed the Criminal Investigation Detachment to take over again, and Deputy Captain Zhao Rongsheng served as the task force leader. The first order he gave was to ask the technical police of the Municipal Bureau and the technical police of the branch bureau to investigate the scene again. As a result, I have not received any notification until now, which shows that they have not found traces of poisoning, especially the residue of poisons."

"You mean the murderer doesn't necessarily cast poison gas?"

"Yes, the standard state of cyano-hydrogen is liquid, and it will disperse when exposed to air, but the dispersion process takes a certain amount of time and cannot completely evaporate like alcohol, and it is impossible not to leave any poison residue."

"This is strange. Gas is neither solid nor liquid. It is almost impossible to control its dispersion range and direction. It is a residential area. Other people's homes are fine, but their homes are in trouble. This is not easy to explain!"

"I've been thinking about this question, where did it come from, and if it's a premeditated crime, then how did the murderer cast it."

"Have you ever thought?"

“Not yet.”

Han Bo sighed lightly and said with a wry smile: "I plan to go to the scene later and have no clue. Going to the task force can only cause trouble for the police officers in charge of the case. Why not go around and see if there is any gain."

This case cannot be delayed, and the news of death from poisoning and poisoning cannot even be leaked, otherwise it will cause panic among residents and even citizens.

Du Zhigang nodded and agreed, "Go and pay attention to safety when you go to the scene. If there is any residue in a corner and it is still evaporating and dispersing, it will be troublesome if you accidentally inhale it."

"Co-Co-President Du, I am a chemistry student, I will pay attention."

He walked out of the captain's office and came to the political commissar's office. Political Commissar Guo was not there, and Yao Jie was not there. He asked a comrade in the General Office. It turned out that Political Commissar Guo was in a meeting in the front building and introduced Yao Jie to the comrades from the Propaganda Department of the Provincial Department.

It was not appropriate to leave her behind. Just as she was about to call and ask, Li Xiaolei called in first.

"Husband, although the dormitory is a bit simple, the surrounding environment is OK, but the pipes are too old and the water pipes are broken. I need someone to help me repair them. You can go and I can handle it."

This is the case with the old house. To take a step back, it is already very good to have a house to live in. Many police officers were transferred to the provincial department and could only live in collective dormitories.
