The public security department attaches great importance to homicide cases, second only to gun cases, far more than other criminal cases.

First, because the social danger of homicide is the greatest among all criminal cases, and second, China has a tradition of cherishing life, and there is a saying that "human life is a matter of heaven". The higher the detection rate and the faster the case is solved, the more it can reduce the luck of those who attempt to kill people, which is conducive to deterring and suspending related crimes and protecting lives.

However, police officers are human beings, not gods.

Some murders can be solved quickly, while others are like looking for a needle in a haystack, and hundreds of police forces may be mobilized and millions of dollars may be spent on money, but the murderer cannot be brought to justice.

With a clear direction for the investigation, the Western Suburbs Public Security Bureau quickly took action.

Director Ding Chengyou and Deputy Director of Criminal Investigation Zhang Yiliang personally commanded the serious crime team, and the serious crime team was short of manpower, so they were urgently transferred from the criminal police teams in each area of responsibility. Considering that some enterprises often organize their own project bidding in order to save costs, instead of entrusting professional bidding agencies. Under their orders, the cyber police of the Cyber Supervision Brigade also searched the Internet for bidding information on anti-corrosion projects.

I didn't sleep well all night last night, and if it weren't for the worry that they would still not be able to find the first scene on the premise of pointing out the direction of the investigation, Han Junzao would have gone back like Zhang Lin.

I slept in the lounge opposite the director's office, and woke up at half past four in the afternoon.

When I walked into the conference room of the Criminal Police Brigade, I saw that it was full of smoke, and the cigarette butts in the ashtray were piled up like a hill, making it difficult for people to even breathe. The phone rang one after another in the police room next door, and one after another materials were sent in by the female policemen one after another, and they were thrown away at a glance, and they were thrown everywhere.

Jiang Yi didn't seem to be sleeping, he was still in good spirits, and when he saw him, he put down the phone and said, "Master, you're up, are you hungry, I'll help you find something to eat." ”

"No need," Han Jun glanced at Ding Chengyou, who was resting on the table, and asked in a low voice, "How is it, is there any progress?" ”

"As soon as the meeting ended in the morning, the Wang team personally went to the agents and dealers to understand the situation, and they were very cooperative, and we made a copy of the shipping bill and delivery records, and there were many clues, which needed to be checked one by one. As you know, Jiangcheng's shipbuilding industry is so developed, there are dozens of large and small shipyards along the river, and they have more or less purchased. ”

Painting often accounts for one-sixth of the total cost of an ocean-going vessel. Less than millions, more than tens of millions, and from time to time to maintain, it can be said that the shipyard is the main customer of heavy anticorrosive coating enterprises. There is nothing wrong with them starting with the shipyards, after all, most of the shipyards are by the river and relatively concentrated.

Han Jun nodded undeniably, took the clue register she handed over, and asked while flipping through it, "How long do you estimate it will take to complete the shipyard inspection?" ”

"It will be tomorrow afternoon at the earliest, there are so many people in total, and the grassroots police station can't act rashly, otherwise it will be easy to startle the snake. After all, catching the murderer is the ultimate goal, otherwise it is useless to find the first scene. ”

In the penultimate line of the last page, it was written "Jiangcheng Chemical Industry Group", Han Jun showed a casual smile, put down the registration book and said: "Ginger, let's try our luck too, we are idle anyway." ”

"But...... But the Ding Bureau ......"

"Seeing that he is drooling, he must not have rested well these days, don't wake him up, let's go ours, talk to your colleague."

The leader didn't say that she had to stay here, and she really didn't have anywhere to stay here to help. People are investigating the case outside, and she is smoking second-hand smoke here, and she has long wanted to find a chance to escape. As soon as the master spoke, Jiang Yi couldn't ask for it, said hello to his comrades who were sitting in the corner sorting out the materials, and picked up a copy of the unbound clue list and slipped away.

I showed my face in the morning, but only a face.

If you want to really raise your eyebrows, you can only catch the murderer with your own hands. As soon as she went out, her fox tail was exposed, and she happily asked with a copy, "Master, which one shall we go to first?" ”

Han Jun pretended to ponder for a moment, and smiled casually: "They check from the front to the back, we check from the back to the front, and go to the last one first." ”

"Okay, just the last one, God forbid, don't let us run in vain."

I want to catch the murderer and go crazy, what a girl who doesn't know the world, Han Jun glanced sideways at her, frowned and said, "Ginger, are you going to go empty-handed?" We're here to catch the murderer, not to travel. Go find a way to get a gun, get a deputy handcuffs, and if you have body armor, bring one for me, I'll wait for you in the car. ”

Jiang Yi then remembered that she had nothing with her bare hands, scratched her neck and said softly with an embarrassed face: "Master, domestic is not abroad, gun control is very strict, I just joined the work, they won't lend it to me." Even if you borrow it, you have to apply for it first, and you have to sign it before you can borrow it. ”

"What then, go to the cafeteria and find a kitchen knife?"

Jiang Yi found that he was very useless, and hesitated for a while before he said, "Master, I ...... I...... I can borrow batons, the kind that can be electrocuted. Handcuffs are no problem, body armor is not needed, there are not so many guns in the country. ”

Looking at her embarrassed look, Han Jun almost burst out laughing, waved his hand and urged: "The baton is a baton, it's better than empty-handed, remember to check if the electricity is full, don't just be a stick when the time comes." ”

"Don't worry, I'll pick a new one and make sure it's easy to use."

The first one is on the riverside and is an oil depot project under construction. Migrant workers work long hours and do not finish until they are out of sight.

The project manager, the constructor, the safety officer and the supervising engineer were all there, and after listening to the intention, they were directly taken to the warehouse, where more than a dozen barrels of fluorocarbon paint produced by AkzoNobel were neatly stacked, and none of them were opened. Dig out the photos of the victims from their mobile phones, they haven't seen them, and nothing is expected.

I found a small restaurant on the side of the road, had some dinner casually, and rushed to the fine chemical park more than ten kilometers away.

Jiangcheng Chemical Industry Group is very famous in this area, covering an area of more than 200,000 square meters, and is a world-renowned professional manufacturer of diphenylamine and its downstream products. The main production of diphenylamine, alkylated diphenylamine, antioxidant, liquid ammonia, ammonia, etc., widely used in medicine, pesticides, gunpowder, dyes, grease, lubricating oil, plastics, synthetic rubber and its products and other fields.

A large group and a large company, the twelve-story office building is more magnificent than the district government.

As soon as he heard that Han Jun was from the Provincial Department of Justice and Jiang Yi was from the District Public Security Bureau, he immediately invited the two to his big office on the tenth floor.

"Investigator Han, Officer Jiang, I am responsible for safe production, otherwise I wouldn't have been off work so late, I don't know if the procurement department has purchased the two anticorrosive coatings you said, but the old factory is really engaged in equipment maintenance during this time, anti-corrosion is a very important piece, and the budget is hundreds of thousands."

Han Jun asked knowingly: "Mr. Chen, how far is the old factory from the headquarters?" ”

"Not far, just across the road, I can't see clearly at night, it's very conspicuous during the day, a large vertical storage tank, next to it are pipes."

The murderer who killed by mistake was on the other side, Han Jun didn't dare to be careless, pondered for a moment, looked up and asked, "Mr. Chen, we want to go to the opposite side to see the construction site, I don't know if it's inconvenient?" ”

"It's convenient, what's inconvenient, I'll go find two hard hats, and I'll go with you."

Walking across the road, the three of them came to a gate with a smile, and saw that there was surveillance at the door, and there was a security guard in the communication room next to the door, Han Jun stopped.

"Investigator Han, Officer Jiang, the paint should be in the warehouse in front, and the doorman has the key."

Han Jun nodded slightly, and while looking around, he asked lightly, "Where does the construction team live?" ”

"Spraying paint is not building a house, there are few people. Considering that there is no village in front of the village and no shop in the back, they can't rent a house if they want to, so let them live in the old dormitory temporarily. Didn't we build a new building, our own workers have moved away, the old staff dormitories are empty, and they can't live for a few days. ”

Mr. Chen took out his mobile phone, flipped out a number, and continued: "Their manager's surname is Zhong, he is a young man, quite capable, and the anti-corrosion work of our group is basically handed over to him." ”

Han Jun walked into the communication room and said casually: "Mr. Chen, can you please ask Manager Zhong to come over, just say that you want to see the progress of the project." ”

Mr. Chen was stunned for a moment, and couldn't help asking, "Investigator Han, Officer Jiang, is there something wrong with Xiao Zhong?" ”

"It's just to learn a little bit about the situation from him, it's so late to say that someone in the Public Security Bureau is looking for it, and it's okay to scare people out of something, Mr. Chen, what do you say?"

"Yes, but that young man is really nice, very capable, and very good at things."

After making the phone call in front of the two of them, after a while, a black Santana sedan drove over from the factory, and a twenty-eight or nineteen-year-old young man pushed the car door and said with a smile as he walked: "Mr. Chen, it's so late and so hot, you don't sit in the office and blow the air conditioner, you're too dedicated." ”

There are two doors in the communication room, one facing the factory and the other facing the road, seeing that the master was leaning back against the north gate and glanced at her, Jiang Yi felt a pang in her heart and stood by the door quietly.

Zhong Haijun walked into the communication room, only to notice that Mr. Chen and Han Jun in civilian clothes on the opposite side took out a bag of soft China as usual, pointed to the sign outside the window that "strictly prohibits fireworks", and made a very exaggerated gesture, handed over a cigarette and said: "Mr. Chen, we are all outside the telescopic door, smoking one is not a violation of the regulations, I will light it for you." This is your friend, come on, get one. ”

He was really good at things, and when he saw Han Jun taking the cigarette, he turned around and prepared to give it to the security guard. When I saw Jiang Yi wearing a police uniform, and when I saw that Jiang Yi had closed the door, the whole person was stupid all of a sudden.

Mr. Chen didn't know why, took a puff of cigarette, and teased as usual: "Xiao Zhong, the comrades of the Public Security Bureau want to find out more about the situation with you, you kid must have done nothing good, you must have made some money with us, and went outside to make the girl's belly bigger, and you don't want to admit it, right?" ”

Zhong Haijunqiang suppressed the panic in his heart, turned around and said, "Mr. Chen, you ...... Don't be kidding, the Public Security Bureau is looking for me...... Find out what is going on. ”

It's so late, and he will go abroad with Vice Governor Kang tomorrow afternoon, Han Ke didn't have time to ink with him, pointed to the chair, and motioned for him to sit down.

"Manager Zhong, the deceased has sperm spots in the yin-dao, and there is surveillance outside. If nothing else, blood stains can be found in your car and on the construction site. If you don't know, you should know very well why we came to you unless you do. ”

"What...... What deceased, what sperm spots, Comrade Public Security, you ...... What do you say? His face was pale with fright, the beads of sweat on his forehead were as big as soybeans, and his expression had betrayed him, but he was still pretending to be confused.

"Listen to me."

Han Jun sighed lightly, and said earnestly: "It's okay if you don't admit it, I don't want you to admit it, I just want to tell you that I am sorry and very sad, how can you say that you are such a shrewd and capable person to do such a stupid thing, it is like intentional murder if you miss and hurt people, if you meet those forensic doctors who are not skilled in learning, you will not be able to wash it away if you jump into the Yellow River." ”

The master was so godly that he didn't go to the scene, and he concluded that he was the murderer at a glance based on the suspect's expression and reaction, which not only stunned Mr. Chen and the security guards, but even Jiang Yi was taken aback.

Zhong Haijun's panicked appearance made her realize that she couldn't make a mistake, and was about to take out the handcuffs, Han Jun continued: "Turn yourself in, don't make a mistake again, call 110 with your own mobile phone, and we will sit here and wait with you." ”
