Mystery Case Tracing [Criminal Investigation]

The three of them were holding boxes of lunch in the car and sharing the details of their home visits while eating. In fact, the professional ability of the staff in the community is not the best. Qi Chuchen gradually cultivated her as a matchmaker from the first person, and also taught her something from time to time. The main reason: this girl has a good sense of proportion. Regarding Qi Chuchen's arrangements that may seem inexplicable, I never ask more, just follow them. When he was teaching, he immediately asked if he didn't understand, and didn't worry that Qi Chuchen disliked her stupidly, so he asked the bottom line to understand.

In the end, the three people mainly talked with the staff and the director of the police station. It was not the first time that they cooperated. Before, many things in the community had been dealt with in countless ways, and it was considered to have a certain tacit understanding.

After three o'clock, Qi Chuchen received WeChat: back.

He looked up in the rearview mirror and Zheng Shikai walked in from the direction of the gate. He motioned to the other two not to speak, and then the three of them got down and hid in the car.

Until Qi Chuchen received WeChat again: Entered the door of the building.

Qi Chuchen got up and patted the two of them, opened the door of the car, followed Zheng Shikai upstairs, and walked to the door of Zheng Shikai's house. The head of the police station stretched out his police uniform and knocked on the door.

Zheng Shikai opened the door half a person wide and put his hand on the door. He saw the head of the police station inadvertently against the door: "Are you?"

Qi Chuchen saw Zheng Shikai's knuckles tightening on the door of the room, only to forcefully turn white and then relax immediately, his tone slowing down deliberately.

"I'm from the XX community and came here for your mother's affairs, do you know?" the director said.

"What's wrong with my mother?" Zheng Shikai's hand on the door slid down a bit and held it on the doorknob.

"Go in and talk, you won't be able to finish it for a while."

Zheng Shikai didn't say a word, opened the door, stood beside him, and let the way open. The three people walked to the only sofa in the living room. Zheng Shikai followed in and took a plastic bench from the wall and placed it on the opposite side of the sofa.

The director of the police station sat directly opposite Zheng Shikai, and the staff sat beside him. Qi Chuchen stood down and saw that there was a bench next to the wall. He walked towards the wall by himself. As soon as he raised his foot, Zheng Shikai turned his head nervously: "Aren't you sitting?"

"I have long legs and your sofa is too short. I will take a stool." Qi Chuchen walked to the wall and picked up the bench while he was talking. When he turned around, he saw Zheng Shikai staring at him, so he simply put the bench next to Zheng Shikai and sat down. Down.

The staff first started, introduced one by one, and then went straight to the topic. Qi Chuchen didn't listen to the specific content of a few people's talks, and sat on the bench to look at the room. Simple furniture and decoration, a total of two bedrooms, one with a wooden bed, one with some goods piled up in a mess, similar to the product pictures in the Zheng Shikai online store, and a few stacks of different specifications are randomly thrown on the floor. A yellow carton, and a few incomplete transparent films. There is also a simple computer desk in the bedroom where the goods are delivered, with a notebook on it, and a large heat shrinkable film sealing machine on the ground next to it.

"I can't help it, I moved out and live." Zheng Shikai said.

"Don't say anything, you can't help it. Your mother raised you so much. Now you are not required to raise her. As long as you assume the guardianship responsibilities, this is not something you can shirk by moving away." The police station chief said in a harsh tone.

"She is neurotic, how can I monitor it?" Zheng Shikai said helplessly.

"Has it been diagnosed? Is there a report? If it is diagnosed as a neuropathy, you must either send it to a psychiatric hospital or take care of it. If something happens, you have to find your family. Your father is old and his behavioral ability needs to be assessed. In the end, the basic responsibility is still you Responsible." The police station chief popularizes the legal guardianship duties of family members.

Community staff came out in due course to make a round, softening the stalemate atmosphere.

"I'm going out to work, so I can't talk to you anymore. From now on, it's better to talk to my dad about my mom's affairs. If my dad can't do it, you can ask my dad to find me. I'm usually very busy, so I'm not at home. You are lucky. I just came back and I haven't had time to change my clothes." Zheng Shikai interrupted the staff.

Qi Chuchen looked at the following table, got up after four o'clock. The chief of the police station stood up and reiterated the importance of this matter again.

Zheng Shikai kept sending them out of the unit door and saw them driving out of the door in a police car before returning to the stairs.

"Vice Detachment Qi, where are you going now?" the head of the driver's seat asked.

"Let me down at the intersection in front of you, I'll take a taxi back to the city bureau, you can go back, today is troublesome." Qi Chuchen pointed to the intersection in front of the traffic light.

Qi Chuchen took a taxi and went straight to the city bureau, getting out of the car almost rushed into Zhang Chao's office.

"Zheng Shikai should be involved in drugs!" The first sentence came out before sitting down.

"Your judgment? How did you find it?" Zhang Chao has also been paying attention to this. He knew that as of yesterday, Zheng Shikai's behavior was indeed abnormal and unreasonable, but he did not reveal the exact point.

"I smell it!"

This is the second time Zhang Chao heard similar words from Qi Chuchen. The last time was in the hotel room where Su Zhankun was murdered.

"What do you smell? Tell me more specifically." Zhang Chao asked.

"The pungent chemical smell is very weak, and it can only be smelled when it is close. It should be a mixture of several kinds, and it can be distinguished at least."

"Isn't the thing on?" Zhang Chao asked, although he knew that if it were on him, Qi Chuchen might have done it a long time ago.

"Definitely not here, so I didn't act today, and Zheng Shikai is definitely not an ordinary next-door hawker." Qi Chuchen remembered the situation reported to him by two stalking police officers on the way back.

Zheng Shikai saw that the police car stopped for a short period of time at first sight, and then kept the frequency to continue walking. He didn't seem to look squint, but he had been observing the movement of the police car. Going to the location closest to the police car, it is possible to try to see the situation inside the car, but in the end it didn't. He hesitated and relaxed into the unit building.

Combined with Qi Chuchen's reaction when he saw Zheng Shikai opening the door, Zheng Shikai saw the police with a guilty conscience and a strong sense of self-protection. However, he finally let go and let the police in the house because he believed that the police were on him. To any substantive evidence.

"We have to ventilate with Zhou Yelong and others about this matter." Zhang Chao picked up the phone and dialed the inside line of the anti-drug detachment.

After the end of get off work time, Zhang Chao took several criminal investigators and the backbone of the anti-drug detachment in the conference room to sit together and listen to Qi Chuchen's introduction of the case. After Qi Chuchen finished speaking, he raised several current doubts:

1. How to collect funds for selling DU products? An order in Zheng Shikai’s online store cost more than one thousand yuan. It is absolutely impossible to be the real transaction amount. Where does the other money come into Zheng Shikai’s pocket?

2. The source of these customers? Of course, it is most likely to be connected through the night.

3. Zheng Shikai participated in the production, and what role did he play in the middle? To help or to lead, where do you get the raw materials?

4. Since Zheng Shikai is not at home and does not leave things on his body, where do the things that are sent come from?

5. In addition to express transactions, are there any offline transactions?

These few questions not only determine Zheng Shikai's final sentence, but also determine how big the pot pulled out along the line of Zheng Shikai, whether it is iron, silver or gold!

"How do you judge that some of Zheng Shikai's transactions were delivered by express delivery?" A police officer in anti-drugs posed a question.

Qi Chuchen explained the order record, purchase ID, and parcel analysis again, and finally added: "Today I found the packaging film of the products sold in his online store at Zheng Shikai's house. How could a normal seller be Before shipping, remove the product's sealing film and seal it again and then send it to the customer? There is only one possibility for such a waste of cost: you have to add something to it."

"We have been digging a line recently. The bulk sellers we caught before have several forms of things on their hands, and the ratio of ingredients is different from what was once popular on the market." Zhou Ye Taki paused after raising a few clues. After looking at Qi Chuchen, he continued:

"It can't be regarded as a new product, or it is not standardized enough, the production process, the raw materials are a bit rough. Since Zheng Shikai is involved in production, then we can't catch the matter like the shipment, we need to formulate a thorough plan. I hope we Can act together."

Zhang Chao just emphasized before the meeting: This investigation is led by Qi Chuchen, and the clues are currently known by a few people in the criminal police detachment, and they have not reached the stage of filing a case. In other words, all relevant information can be transferred to the anti-drug detachment, and the follow-up investigation and solving of the case has nothing to do with criminal investigation, and even the credit should not be given.

And Zhou Yelong’s statement is that everyone cooperates. You have found merits and merits in collecting clues. I will not grab this part of the results. You will still need your support in the follow-up. You can complete this case together beautifully.

Because Zheng Shikai's anti-drug detachment participated in the official investigation, the most direct benefit is that more people are available and more professional resources can be mobilized.

There were more people staring at Zheng Shikai. After losing him twice, he finally found out that his destination for early morning trips from time to time was a poor rural village in the suburbs. The location of this village is rather strange. It is sandwiched between two high-speed highways. There is only a bus station nearby. The bus is half an hour apart. It takes more than half an hour to walk from the subway station and it takes ten minutes to ride a motorcycle.

This village is sparsely populated because there were several chemical plants nearby in the early years, and serious pollution caused the soil and water quality to deteriorate, and some villagers suffered from strange diseases, especially children and the elderly. Although later due to media exposure, the superiors stepped in to investigate and shut down the chemical plant and compensated the victimized villagers a sum of money. However, the village has also successively moved a large number of people away. Most of the residents here are old, weak, sick and disabled. Relief of the villagers.

The village is too poor, the land cannot grow food, there are few villagers with labor force and complete behavior ability, so there is not even a serious village chief.
