Liu Jinghui made various speculations about the identity and relationship between No. 1 and No. 2.

The most reliable one is that they met by chance with an old acquaintance, but No. 2 became murderous because of drug abuse or other reasons.

Jiang Yuan did not object to his speculation, but in the investigation of specific cases, Jiang Yuan was still more willing to follow the evidence.

The evidence now is surveillance footage.

The imaging in Ningtai County is relatively complete. The urban density is not necessarily higher than that in Changyang City, but because of the new equipment and complete configuration, the rationality of the configuration is definitely stronger than that in Changyang City.

It is extremely convenient for a group of people to pull out and watch the image for breaking the eucalyptus.

In other cities, the criminal police officers are very busy every day, that is, they can mobilize a large number of manpower. After the death penalty is over, they still have to do what they need to do. If you want to be like Ningtai County There are very few people who cut out images even a little bit.

As a result, the members of the special team continued to watch the images day and night.

No police officer complained about this.

Normal case detection is just like this.

The three treasures of the detective are images, mobile phones and DNA. No. 1 and 2 can't find anything useful in their DNA, and they are very careful about the use of mobile phones, so the rest is just images.

Jiang Yuan's imaging strategy is more in line with everyone's expectations. As for injuries, when you are a criminal police officer, either your legs or your eyes are affected. If you are not tired of either, you will most likely be injured.

Soon, through the surveillance video, the members of the special team figured out the two people's behavior over the past few days.

Tang Jia made a comparative timetable and posted it on the wall. Without Liu Jinghui's intervention, everyone could see the mystery.

The day before No. 1's death, that is, around 10 o'clock in the evening when the two met unexpectedly, both of them had records of going out.

"The two are several kilometers apart. Find the means of transportation they use." Liu Jinghui saw the clue and immediately got into work mode.

Wang Chuanxing said "Yes" and said: "We are also looking. Mainly because of the surveillance at night, the clarity is a bit affected, and we don't know where the two got in the car."

"Pull out all the taxis passing by nearby." Liu Jinghui said, looking at Jiang Yuan and asked, "Can you do image enhancement?"

"Okay, but in the night environment, you must not be able to see your face." Jiang Yuan was still a little unable to follow Liu Jinghui's train of thought.

Liu Jinghui said: "You don't need to see the face, you just need to be able to see the license plate. At 10 o'clock at night, you can find the license plates of all the taxis passing by within half an hour. Just call and ask. Show the driver the photo."

Wang Chuanxing was stunned when he heard this, and said hurriedly: "What if it's an online car-hailing service?"

"This kind of people don't like to use online ride-hailing. The maps are too detailed and there are too many driving recorders. However, if the taxi can't find anyone, just ask the online ride-hailing company directly about the vehicles passing by during that period." Liu Jinghui told This aspect is very familiar, and many eucalyptus will use this set.

Jiang Yuan naturally had no problem doing image enhancement. He sat down in front of the computer and with one operation, he enhanced the images of all the license plates of taxis passing by within the specified time.

Tang Jia took the license plate and immediately made a phone call, then added the driver's WeChat account and sent photos of the two deceased people to the drivers.

Not long after, feedback came back.

"Both cars were driven to a hot pot restaurant. Lakeside Old Hot Pot." Tang Jia quickly came back to report.

Liu Jinghui laughed: "No. 2 likes hot pot very much. He ate hot pot with No. 1 the first day, and the next day he killed No. 1 and ate hot pot by himself..."

"Go and have a look."

Jiang Yuan actually didn't bother to look at the video. The hundreds of surveillance cameras looked like they could really blind people. That’s why the police don’t like to find people’s mobile phones. The surveillance system is actually not as easy to use as imagined.

Finally finding another scene, Jiang Yuan took people there without hesitation.

This is a hot pot restaurant built in the suburbs. It is quite large and is built next to an artificial lake. There are about 20 tables in a row along the lake.

"From the Criminal Police Brigade." After entering the hot pot restaurant, Mu Zhiyang showed his ID and walked in.

There weren't many people in the hot pot restaurant, which wasn't a place to eat. A group of policemen came clattering in, which immediately attracted everyone's attention.

A male waiter at the front desk lowered his head and walked to the kitchen.

When Wang Chuanxing saw it, he immediately shouted: "Don't move yet, stand there."

It's okay if he didn't shout, but if he did, the waiter immediately ran away.

The entire process, if we use an accurate word to analyze it, should be called "police running in excitement".

Not only Wang Chuanxing, but also Mu Zhiyang, Tang Jia, Dong Bing and others all started running. It’s not all about grabbing credit, the main reason is that it’s hard to see a criminal suspect running away so arrogantly when facing the police.

Four or five people pounced on him. The waiter was so frightened that his legs and feet became inoperable. He was tripped when he jumped out of the window.

Wang Chuanxing jumped onto the male waiter with a hurdle move on the spot.

Next, there is the traditional police performance show.

Jiang Yuan was wrapped up behind Shen Yaowei and others. He waited until the escaping waiter was handcuffed before he stepped forward.

"Why are you running?" Meng Chengbiao was still hiding behind Jiang Yuan, but now he came out slowly.

The waiter said nothing.

"What's your name?" Meng Chengbiao asked with a smile, but he was asking the waiter next to him.

The people next to me were also a little panicked. The colleagues who were chatting and laughing ten minutes ago were now being picked up by a few big men. It was a bit weird no matter how you thought about it.

"Li Qingsong." The manager came over, said his name, and asked, "What's the matter?"

Meng Chengbiao didn't say anything, only said: "Gather the staff together, we have a few questions to ask. In addition, is there any room that we can borrow?"

The manager hesitated and pointed to a box.

Meng Chengbiao asked the male waiter Li Qingsong to be brought into the box, and then took out a rapid drug test box and began to test Li Qingsong.

"I don't take drugs." Li Qingsong panicked.

"Tested?" Meng Chengbiao smiled.

Li Qingsong was stunned for a moment when he was asked. After a while, he came to his senses and whispered: "I've seen it before, I've seen people use it."

"Most people may not have seen it before." Meng Chengbiao chuckled twice. Without listening to Li Qingsong's explanation, he pulled out his hair, stuffed it into the test kit, and then said: "What you are telling me now is still a surrender. If it is tested, it is not ”

Li Qingsong lowered his head again.

"Is there surveillance in the store?" Shen Yaowei opened the door and asked the manager, and received a positive reply.

No need for Jiang Yuan to say, a few people naturally went to the computer to adjust the monitoring.

Li Qingsong pretended to be calm.

Soon, Shen Yaowei returned.

"I came here on the 1st. I had a backpack when I came, but I didn't take it with me when I left. Where did I put it?" Shen Yaowei asked Li Qingsong directly.

Li Qingsong's eyes changed when he heard about the backpack.

"If you don't tell me, we will send the police dog here." Meng Chengbiao's voice was very relaxed.

Li Qingsong looked around and finally said: "I'll just go to the kitchen."

Meng Chengbiao winked at Wang Chuanxing and asked, "What's in it?"

"Bing." Li Qingsong's eyes drooped.

"how many?"

"One kilogram." Li Qingsong basically gave up, his whole body was limp.

Meng Chengbiao knew that this was the prime time for the interrogation and immediately asked: "Where to take it?"

"I don't know, I'll just send it to the courier point." Li Qingsong said.

Meng Chengbiao understood immediately and asked: "Who is your person?"

All packages entering and exiting express delivery points must be inspected. Ordinary people can basically ensure that they do not contain dangerous goods if they send packages directly. But to send drugs, you usually need help from the inside.

Li Qingsong had reached this point and said without any further words: "Wang Luo."

"I'll call Director Huang." Jiang Yuan didn't have many people around him. If he wanted to arrest someone again, it would be better to send someone over directly.

However, the core issue now has shifted from arresting people to getting goods. In other words, destroying this drug transportation chain is the top priority right now.
