At around 8:30 in the evening, Fei Zizheng led his men back to the police station and summoned the core members of the task force to prepare to work overtime overnight.
In the bright office area, more than 20 criminal investigation experts looked at the mountain of files and documents on the conference table with slightly frustrated expressions.
Fei Zi was standing next to the information blackboard, and said to everyone with a serious expression: "Let me tell you my judgment first. From the information we have so far, the bandits hijacked the water truck of the water delivery company, controlled the water delivery workers, entered the crime scene to deliver water, set up the bomb, and evacuated alone from beginning to end. In my experience, this method of committing crimes does not seem to come from a criminal organization. Working alone is indeed less risky for the criminal himself, because there are no accomplices, but if it is a big risk for an organization. You are alone, and it is easy to have an accident when hijacking the water delivery worker. So I infer that the core motive of this case is most likely revenge, and the reason for the revenge is the mine disaster."
After saying that, Feizi started drawing a picture on the information board and continued to add: "According to this idea, the technical team provided us with a very useful piece of information, that is, the way the criminals made the explosives and the technology of installing the timing device are more consistent with the blasting personnel in special industries in society, such as blasting engineers in engineering units, blasters in the mining industry, etc. For this reason, we visited many units today and retrieved blasting personnel with formal qualifications and records from the information databases of various units..."
After Fei Zizheng quickly wrote down various information and relationship diagrams, he turned around and looked at the members of the task force: "Tonight's work is to identify. We will compare the filed information we have obtained with the families of the mine victims and the special workers of the three major associations one by one, find commonalities, and identify the culprit as soon as possible! Since the blasting personnel of each unit have not logged into the computer, our workload is relatively large. Everyone, please work hard and stay up all night."
In the office area, everyone looked at the piles of original filing documents, and then glanced at the worker information just sent by Baolong Mining. Their heads were buzzing, and they all felt that they might die suddenly here tonight.
Fei Zizheng walked to the conference table, put his hands on the table and continued, "I personally think that if it is really out of revenge, he will definitely commit crimes again. If we can find out his identity and lock him up as soon as possible, we will definitely save many innocent people. My direction may not be correct. If we make a mistake, we will have to start all over again, so we don't have much time. Please work hard."
Everyone nodded and started working.
Fei Zi took out more than a thousand cash from his dry wallet, threw it on the table, and said to his assistant, "I'll pay for the coffee and supper tonight. I'll try my best to meet everyone's needs."
Everyone laughed when they heard it.
After saying that, Fei Zizheng also sat down and joined in the work.
…
Beside a street in Longkou District, Su Tianyu was lying in a car and sleeping soundly.
“Bang!”
The sound of the car door being opened was heard, and Li Yuan, carrying a briefcase on his back, sat in the back seat. He looked at Su Tianyu in surprise and said, "He's sleeping soundly."
"He hasn't rested for more than thirty hours." Bai Hongbo replied and reached out to push Gou Liuzi's shoulder.
"Ah?" Gou Liuzi suddenly woke up, his eyes were red, and he looked around in confusion.
"Brother Li is here." Bai Hongbo reminded.
"Oh." Gou Liuzi rubbed his red and swollen eyes, slowly turned back and asked Li Yuan: "Did you get the information?"
"I got it," Li Yuan reached out and took off his backpack, whispering, "It's all in here."
"Okay." Su Tianyu took it and nodded: "Okay, let's continue to do our work."
"Why do you want to register these blasting personnel?" Li Yuan asked curiously.
Su Tianyu picked up the cigarette box and replied, "It was the police station who showed us the way. They have been looking up information on this for a day and they should have found some clues."
"They think the murderer might be a professional blaster?" Li Yuan already understood what Su Tianyu meant.
"Yeah, it should be." Su Tianyu lit a cigarette: "It is very likely that it is at the worker level."
Li Yuan was stunned for a moment: "Then why don't you just conduct an internal self-inspection and find suspicious persons? This is more convenient."
"I've asked Dabai to check and notified Changqing, but it didn't work." Su Tianyu shook his head helplessly: "The families of the miners who died have been contacted so far, and there are very few people with blasting capabilities. Dabai asked them personally, and they have no doubts."
When Li Yuan heard this answer, he felt a little worried: "If it is really a problem at the workers' level, then the regulators will catch the people first, and then make a fuss about it and throw dirty water on us. Then... the situation of the three associations will be very dangerous."
"Yes, so we have to check it quickly." Su Tianyu took a puff of cigarette and immediately replied: "Let's not talk about it for now, let's do the work first."
"Okay, call me immediately if you have any news."
"Yeah, that's it."
After the two finished chatting, Li Yuan pushed the door and left, while Dabai drove to Zhanan.
On the way, Su Tianyu briefly looked through the information and contacted Kong Zhenghui, preparing to let him investigate the matter. Because apart from Su Tiannan, he was the one who knew the grassroots situation best and was familiar with the people in the union.
When Kong Zhenghui answered the phone, he was at the crematorium. Because today was the day of Jiushu's wife's cremation, there were not many people in her family, only a little girl who was in school, so the union was helping.
After Su Tianyu and Kong Zhenghui finished their conversation on the phone, Dabai drove to the crematorium.
…
In the north of Longcheng, on the road leading to District 1, there is a mountain tunnel about two kilometers long.
At night, a cold wind blows.
A young man wearing sportswear and carrying a large mountaineering bag entered the tunnel from the inspection port above the tunnel with ease.
In the dimly lit tunnel, the young man stood beside the stairs, turned his head to look at the exits on both sides, and many memories suddenly emerged in his mind.
It was a hot summer day, and a group of workers were squatting outside the construction area, eating boxed lunches and watermelons they had fished out of ice buckets.
In a mountain area that has not yet been opened, a middle-aged man yelled, "To do this business, you have to be rigorous. You can't just say it's almost there, and you can't just give it a try! If you use the wrong amount or the wrong data, it will kill many people. Do you understand?!"
A young man in his twenties kept his head down and did not talk back.
"Remeasure!" the middle-aged man ordered, "After you're done, we'll eat."
"Yeah." The young man left somewhat angrily.
A foreman nearby gently advised: "Hey, come on, you're scolding your own child so harshly."
The middle-aged man smiled, did not respond, just bent down and sat down to pick up the lunch box which was covered with a thin layer of dust.
“Buzz!”
A fast-moving off-road vehicle pulled the young man back from his memories. He looked at the dim tunnel and walked towards the most important load-bearing pillar of the north entrance in his memory.
