Approaching the Spring Festival, Li Xiaolei was busy. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The work of the economic adviser of the Yushan County People's Government can not be delayed, both to move and to prepare for the New Year, bacon, sausages and other local specialties to buy hundreds of copies, first pack and consign back, Li Jiaqi of Nangang is responsible, Wang Yan of Sigang is responsible, and the aunt of the hometown of Sihe asks for help, and each family is divided before the New Year.

Compared with Li Xiaolei, Han Bo seems to be a little idle.

Go out early and return late, from 8 to 5, either go to the provincial hall, or wander around the city with Ge Zhengjian, knowing that he is investigating the case, and by the way, he is familiar with this strange city. I don't know that I think he travels all day long and doesn't do his job.

The task force did not want to fight an uncertain battle, and did not devote much energy to analyzing the question of where the poison gas came from. The leaders have reminded them more than once that they are always busy finding out the suspects and never paying attention to them.

"Han, check it out, it's really there!" Ge Zhengjian was excited, the physical evidence inspection report he just got would be able to strongly support his previous speculation.

This is a significant development, and the year is good to have this report.

Han Bo weighed it, held his mobile phone and said: "You can't be happy too early, hurry up and check the cars screened out the day before yesterday, find out the ins and outs as soon as possible, and the suspect must be arrested and brought to justice, otherwise with this inspection report, this case is still a pot of rice." ”

The approximate time period is clear, and the time since the case occurred is not too long, as long as there is a clear direction, it is not difficult to find clues. The day before yesterday, a total of 17 vehicles were screened from the traffic surveillance video, and the model, license plate number, and owner information have all been mastered, and the rest of the work should not be difficult to do.

Ge Zhengjian was very excited to have the opportunity to participate in the investigation of such a big case and assured: "Don't worry, Han can rest assured, I will be able to find out the truth of the case before 4 pm at the latest." ”

"Okay, waiting for your good news. ”

A breakthrough has been made, and the case has finally gained some eyebrows, and I can't help but report to the leadership.

Four people died, a family of four, the impact was too bad, Deputy Director Zhang attached equal importance to it, and listened to the report with Deputy Director Wu and Team Du, and the results were jaw-dropping.

"Han Bo, are you sure it wasn't a premeditated poison killing?"

"It is certain that, from the evidence available so far, the suspect is suspected of negligently placing dangerous substances, and he does not know or does not know very well how dangerous it will be to do so, and perhaps he does not know the family of the deceased. ”

The blood and internal organs of the four deceased were all detected to contain cyanide ions, and it was Cyanide-Hydrogen, which Han Bo had previously speculated to have killed them. Four people died, and they were suspected of poisoning, and the provincial department required the city bureau to report it once a day, and the Xinyang Municipal Party Committee even asked the city bureau to solve the case during the Spring Festival.

Du Zhigang knew how much progress the task force had, and began to move several lines in unison, listing one suspect after another, and then eliminating them one by one. Now that there are no suspects to rule out, the attention is on Fu Liqing, who has been detained in the detention center.

The authorities are confused, and the bystanders are clear.

The young deputy director-level investigator decided that the breakthrough was in the "modus operandi", and in the past few days, he led the police officer Ge Zhengjian of the corps to pursue it with perseverance, and he really found out his eyebrows.

For someone else, it's a credit.

The point is that he is none other than him, and he should have provided guidance to the task force.

The county officials are not as good as the current management, and the relationship between the provincial department and the Xinyang City Bureau is very delicate, so the Du Corps asked quietly: "Director Zhang, Director Wu, why don't I call the city bureau to report the latest situation, and ask the task force to immediately adjust the deployment." ”

"If you find out this, the case is about to be solved, what deployment can be adjusted!"

The provincial department needs prestige, Deputy Director Zhang snorted coldly, and said expressionlessly: "In the process of solving the case, Comrade Han Bo has reminded him more than once. However, they take the opinions of the higher-level business guidance units as the wind on their ears. Wait a minute, wait for Xiaoge to implement the situation and then report it, Lao Du, after the implementation, you and Comrade Han Bo will go together. ”

What does the criminal investigation corps do, it is to grasp the dynamics of criminal offenses in the province, analyze the laws and characteristics of criminal activities, predict the development trend of criminal offenses, and study and formulate countermeasures to crack down on and prevent crimes; organize, guide, and supervise the investigation and handling of criminal offenses by the public security organs throughout the province;

Directly investigate and handle some serious, extraordinarily difficult cases; formulate a development plan for the province's criminal investigation information work, organize the popularization and application of criminal investigation information technology; provide expert and information support for major and difficult criminal cases; and coordinate the handling of cases with other provinces (municipalities, districts).

Although Deputy Director Zhang did not explicitly say that the corps would directly investigate the case, the meaning was very clear, wait for the suspect to be caught, and then hand it over to Xinyang City when the truth is revealed, so that the comrades of the city bureau know that the provincial department is not all sitting in the office, and the provincial department can also solve the case!

The case may seem bizarre, but it's not complicated at all.

As long as the mystery of where the cyanide-hydrogen gas comes from can be solved, the follow-up investigation will be easily solved.

At 10:21 a.m., Ge Zhengjian reported that according to the clues provided by the car owner, he and several police officers of the corps searched for the two suspects......

The truth was revealed, and several department leaders breathed a sigh of relief and immediately sent Han Bo and the Du team to the city bureau task force.

The investigation work has reached a deadlock, several principal members of the special case group are very haggard, and the police officers handling the case are discouraged and their morale is not high.

How can you not think of a small detail?

Team Du sighed secretly and knocked on the table: "Comrades, first report a piece of news, the 01.05 case has basically been solved, the suspect has been arrested, and he confessed to the facts of the crime, but he is not suspected of intentional homicide, but is suspected of negligently putting dangerous substances." ”

It's broken!

I have never encountered such a strange case, and the captain actually understated it.

Not only Zhao Rongsheng, Yang Guosheng and other members of the task force looked at each other, but even the deputy director of the criminal investigation bureau, the head of the criminal investigation detachment, and the director of the sub-bureau who attended the meeting together were stunned, unable to believe that this was true.

"Comrade Han Bo, please give us a briefing on the situation. ”

"Okay. ”

Han Bo looked back behind him, and the police officers who came over with him sent a stack of architectural drawings.

"Leaders, comrades, I have raised the difficult and suspicious points of the 01.05 case more than once before, where did the cyanide-hydrogen-cyanide-hydrogen come from, if the four deceased were killed by him, and how did the murderer take samples to poison them? ”

With the help of colleagues in the corps, Han Bo first hung up a plan of the community, and the location of Tan Xingtao's house was marked with a red pen.

"The on-site investigation was carried out three times. Rummaging through the cabinets, almost all the items in the house have been checked. In total, there is such a large place, where is the container for cyanide-hydrogen, even if it is gas, there must be a sealed convenience bag. When I think of this, two possibilities come to mind. ”

"First, on the night of the incident, a sixth person, whom we do not yet know, entered the deceased's house. However, this possibility is very small, Tan Xingtao will not watch a person release highly toxic chemicals in his home, not to mention that he was still awake when he was sent to the second hospital of the city for first aid, if someone really poisoned, even if it was just suspicion, he would accuse it as soon as possible. ”

It turned out that it was not repaired by air conditioning!

Dapeng, a policeman from the special case group sitting in the last row, was nervous and hung his head, for fear of being recognized.

Han Bo had long forgotten about the incident of going to the scene that day, and continued: "The second possibility is the leakage of toxic gases, but this possibility cannot be explained, after all, it is a small community, where thousands of people live, and if there is a leakage of highly toxic chemicals, the casualties caused are unimaginable."

Just when I was about to dismiss this thought, my lover called me and said that the water pipe in the dormitory was broken, the downstairs was flooding, there was no water upstairs, and the toilet was not flushing. Thinking of a situation that the task force learned when questioning, on the night of the incident, the sewers on the third and fourth floors of the unit were blocked, and I realized that there was a possibility. ”

Zhao Rongsheng was confused, and couldn't help asking: "Han, are you saying that the poison gas came from the sewer?"

"It's not a sewer, it's a septic tank. ”

Han Bo pointed to the floor plan that had just been hung and introduced: "Realizing this possibility, I immediately looked for the property to ask for drawings, and found that there was a septic tank under the small garden behind Tan Xingtao's house, and his house was the first to connect the sewer pipe." Looking for the urban construction department to check the pipeline map near the community, I found that the supporting facilities around the community have not been completed. Due to the low terrain, the water drained from this location, this location, and several locations will eventually pass through this well and enter the septic tank behind the deceased's house. ”

"Cyanide-hydrogen, toxic gas coming out of the toilet?"

"So to speak. ”

Han Bo took out a screenshot of traffic surveillance from his bag and said: "These two men, one surnamed Chen and the other surnamed Wang, bought some electroplating equipment at an unlicensed electroplating processing factory in Shiyan District at about 4 p.m. on the day of the incident. The two sides reached an agreement, and the two men found that there were still some residual electroplating solutions in the second-hand electroplating equipment they had purchased.

When the car is driven, it is always swaying, especially when going uphill, and it is not convenient to carry it after pulling it home, so the electroplating solution containing highly toxic cyanide chemicals and acidic compounds is poured into this sewer on the side of the road. ”

It was just like this that he fell down lightly and buried the accident that killed four people. It is also unfortunate that the sewer of this unit of the deceased's house was blocked that day, and the sewer without air flow could not dilute the highly toxic gas, and the highly toxic gas began to spread slowly, and reached the release port in the bathroom of Tan's house. ”

He first suspected that the problem was in the room, so he stared at the toilet, looked for drawings to find the septic tank, and then looked for the pipe network diagram, made bold assumptions, and delineated the possible area and even the specific location.

There is an approximate time period, and it is not difficult to check the vehicles passing through the east during that time period.

You catch murderers all over the world, but it turns out that this is not a murder case, the direction is wrong, how to investigate!

Wang Xinlei, the captain of the detachment, was very uncomfortable, and Zhao Rongsheng was very embarrassed.

Han Bo didn't want to waste time, and said with a smile: "Detachment Zhao, there are several inspection reports that have been handed over to you, and the two suspects are escorting here and preparing to take over." ”
