Mystery Case Tracing [Criminal Investigation]

"It was polluted by chemical factories in the early years and was not sensitive to chemical smells. The village is sparsely populated. This village is an excellent DU den. Maybe it is not just Zheng Shikai who did this here." Qi Chuchen looked at the image data in the projector. Say.

"We think so too, so we arranged a few people to stand guard, also to find out how often Zheng Shikai came over, to see if he only had this point." Zhou Yelong said.

"Now there is still a doubt, how can the DU products be delivered to Zheng Shikai? Is there anyone other than Zheng Shikai to deliver the goods?" Qi Chuchen said.

"Several ways, someone sent it to the door, met in the dark or other places to deliver." The anti-drug team analyzed by one person.

"I tend to send it to the door. The night has been investigated, and this kind of thing is too risky to circulate in the night. Judging from the route selection of Zheng Shikai to the manufacturing site, he is very cautious, not afraid of trouble, and will definitely not let things in his own Keep it on hand for too long. According to the feedback from the people who monitor Zheng Shikai, according to the people he usually contacts, there are two ways to deliver it to the door: takeaway and express delivery." Qi Chuchen said.

Zhou Ye Taki straightened up when he heard the word "express": "I have a clue that I haven't had time to share with you."

The anti-drug detachment selected several returning customer IDs in the online store transaction records provided by Qi Chuchen, and selected a single package that would not raise suspicion in the recent purchase order, causing the express company to accidentally damage the package. When the package was taken back and opened, there was something in it. After weighing, the value was not too high, but it definitely did not match the sales amount of the online store. After testing the contents of the package, it was very similar to the rough-made goods they found before. This discovery not only confirms that Zheng Shikai uses express bulk cargo, but also confirms that Zheng Shikai's online store is not a real way to sell and collect money.

"How come the package was accidentally damaged?" Gao Rui heard this word quite fresh.

"Unscrupulous sellers sell three-no power banks. The packages were placed in the open for a long time. After the sun was exposed, they were short-circuited and burned a batch of packages. Unfortunately, Zheng Shikai's packages were in the batch that was implicated." Zhou Ye Taki said lightly.

"How many are the batches?" Gao Rui found that the anti-drug detachment did not do too much.

"One batch means that only Zheng Shikai's package is real. Dozens of other packages are made by courier companies. The pictures on the scene seem to have suffered a serious loss anyway. All flammable materials burned too fast, and they couldn't be rescued when they were discovered. ."

...

They're all big guys, they can't accept it.

"Zheng Shikai receives relatively few express delivery, but he orders takeaways every day. We can start with the delivery staff to see if there are any hidden people." Qi Chuchen finished his sentence and added.

"We have to do it as soon as possible. Although the incident of package damage seems normal on the surface, Zheng Shikai is not a normal person. He may be very suspicious. I don't know if this incident will arouse his alertness."

After the meeting, it was determined that there might be a possibility of delivering DU for take-out. Qi Chuchen took a few people and pulled out Zheng Shikai's call records and cell phone interview records for the last three months, and checked them one by one.

Qi Chuchen's thoughts were very simple and rude. This matter must be fixed, so one or two people will send Zheng Shikai to the door to find out the delivery staff that Zheng Shikai often contacts to pursue. Another question needs to be considered: how did the person who delivered the goods get the DU products and then give them to Zheng Shikai.

Those who stalked at the entrance of the village found that, except for Zheng Shikai, the other people who came in and out were basically villagers or postmen from the post office. Sometimes government staff came down to work on the ground, but there were basically no other migrants. Because it is impossible for an individual to rush up and search, they have been just stalking, but they have confirmed that Zheng Shikai always comes to this village every time he goes out and stays outside for a long time. A house in this village should be the only production site for Zheng Shikai.

Yes, all night call records, delivery time. Qi Chuchen discovered that there was a phone number that Zheng Shikai would call at noon every afternoon when shipping, except for the rare two or three calls made before shipment. It is very rare that two or three times compared to the online store’s shipping records, the orders issued on the same day are all orders from real buyers or purchasers.

Qi Chuchen quickly called the phone to check the owner's information. The owner's name is Bao Guohua, 48 years old, and he runs a small restaurant. Qi Chuchen checked Bao Guohua's household registration information. He was born in the village where Zheng Shikai was founded. He bought a house in the urban area three years ago and moved his household registration to the city. He is married and childbearing, and has an only child 25 years old this year.

Qi Chuchen also checked the restaurant run by Bao Guohua and opened a hand-made noodle shop five kilometers away from Zheng Shikai's home. They sell steamed buns in the morning and dumplings during the day. The noodles are all handmade.

"How delicious is this? It is called two times after five kilometers in three days? The noodles are smeared when they are delivered so far. I'm afraid that the noodles delivered every day are not what we thought." Qi Chuchen dropped a bunch of materials. On the table, he lifted his leg onto the table, took a cigarette out of his pocket and bit his mouth to light it.

Gao Rui glanced at Qi Chuchen: "The leader should pay attention to his appearance and put his feet down, okay..."

"Don't let go, if you talk about it again, I will give you extra work..."

Gao Rui shut up.

"How do you check this package of Guohua every time you deliver it?" Qi Chuchen flicked the ashes.

Gao Rui's heart: It's the same as if I just shut up and didn't live.

The morning sun filled the meeting room, and the breath of spring blossomed in every inch of sunlight. Qi Chuchen opened his red eyes and introduced Bao Guohua's line.

Bao Guohua owns a second-hand van, who usually pulls flour. By calling road monitoring, Bao Guohua drove this car every time he delivered meals to Zheng Shikai. Although Bao Guohua bought a house in the city, the house should be used for his son's marriage, and he and his wife often went back to live in the village.

"We often see this car, and it goes in and out of the village almost the next day." The people stalking in the village looked at the screenshots and confirmed Bao Guohua's path.

"If Bao Guohua is the person in charge of the delivery, then we can estimate that Zheng Shikai's offline transactions in this city are most likely to be delivered by Bao Guohua in the form of delivery."

"The manufacturing point is determined, the delivery person is determined, the delivery is determined, and the next home for online purchase is determined. The real payment method and the source of the raw materials have not yet been determined." Qi Chuchen concluded.

"The latter two can be caught for retrial. Now we are discussing closing the net." Zhou Ye Taki stood up.

It is necessary to catch the current situation, especially for Bao Guohua, then it is caught when Bao Guohua is delivering the goods, or the catch is finished.

"We recently monitored Zheng Shikai's online store and found that orders are increasing and there is a backlog of shipments. This morning I checked that there were still unsent orders, and there were new orders in the middle of the night." Zhu Zhen said.

"Did there be deliveries yesterday? Did Bao Guohua deliver foods yesterday?" Qi Chuchen asked.

Zhu Zhen glanced at the things in her hand: "Zheng Shikai called Bao Guohua at noon yesterday, and sent the goods once before going to work in the evening, and the delivery was XX express."

"Contact the courier company. Yesterday, all the messages he sent were intercepted. No matter in which link they were all intercepted, the previous ones were urgently dealt with and the ones that had not been delivered were intercepted as much as possible. Today, if Zheng Shikai will inform Bao Guohua to come to the door. Bulk buyers from other places , I now notify the locals to cooperate with the arrest.” Zhou Yelong confirmed the arrest plan with a few words.

At eleven o'clock at noon, Zheng Shikai dialed Bao Guohua's number: "Baihuilu Leyi Community, three or two beef noodles are added."

Bao Guohua hung up the phone with just an "um" for this unfamiliar road name and community name that was not within the scope of this city.

At twelve o'clock, Bao Guohua carried an insulation bag on his second-hand van and shook his way to Zheng Shikai's house.

The van stopped on the road outside Zheng Shikai's community. Bao Guohua just got out of the car with a thermal bag and closed the car door. A couple quarreling quickly ran over from the side. The young girl rushed forward in a panic while crying while covering her face. She stumbled while running in high heels and bumped the bag in Bao Guohua's hand to the ground.

"Blind...!" Bao Guohua didn't finish his sentence. The boy who was following quickly ran over and squatted down and reached out to carry the bag: "Excuse me! What's in it, you see if it broke, I'll pay. you."

Bao Guohua quickly grabbed the bag before the boy's hand touched it, "It's nothing, it's empty, don't walk without looking at the road."

Bao Guohua dusted the outside of the bag and carried it to the community.

The boy continued to chase the girl, "There is something in the bag, don't let me touch it."

Bao Guohua walked to the door of Zheng Shikai's house with the bag, and knocked on the door rhythmically. Zheng Shikai opened the door a crack and stretched out a hand to connect.

"It should be spilled inside, you clean up, things will be fine." Bao Guohua handed over the bag.

Six or seven people jumped down on the stairs, slammed open the door, and pressed Bao Guohua and Zheng Shikai to the ground.

An anti-narcotics police picked up the thermal bag that fell on the ground, opened it and glanced at a leaking bag of soup and water, carefully touched the thermal bag with his hand, and said: "There are a lot of goods in the sandwich."

Bao Guohua, who had been struggling all the time, heard this, and collapsed to the ground.

Criminal investigation, trace inspection, and technical personnel quickly followed upstairs and entered Zheng Shikai's rental house.

When technology opened the notebook in Zheng Shikai's room to check, Qi Chuchen glanced at a green icon on the desktop, and a not-so-good premonition instantly came to his mind. Qi Chuchen had seen this green label. In Ruyi's computer, it was the login port of an underground trading website. Ruyi originally released the mission here and recruited the professional assassin who has not been arrested so far.

Qi Chuchen turned to a small book from the drawer of the computer desk, which recorded in detail how to use VPN, login green label, account number, and password process. After logging in to the green label, how to collect money, how to transfer money, and how to exchange it is clearly written. In addition, there are detailed transaction accounts. Although the abbreviation is used, it can be seen at a glance that it belongs to the DU category.

Qi Chuchen looked at this book with joy: "Sure enough, the grades are too bad, and people with too stupid brains can't do anything."
