As a local policeman, is it appropriate for you to take over the job of a criminal policeman?

Ye Lin and Li Suo opened the door and sat down. "I'm Ye Lin from the Criminal Investigation Team of the Branch. Have you seen the murderer?"

"Well, when I was downstairs, I saw a takeaway truck parked there. When I picked up the takeaway, he rushed downstairs as soon as he entered the corridor. He was walking very quickly." Xiao Wang had already told it again, and his logic was much clearer than the first time.

"Are there any characteristics of the person or the car? Please think carefully. The more clues we have, the more likely we are to solve the case."

"Boss, I really didn't see it clearly. It was raining so hard and our electric bikes were all the same. I didn't look closely. The takeaway boxes were all the same and he didn't put any logo on them."

"Then he got off and rode away directly, still wearing a helmet. All I could tell was that he was neither tall nor short, and he didn't look fat because his raincoat was quite loose."

Ye Lin frowned. According to his description, half of the men met this condition.

"And what else? Did he have a knife in his hand? Or do you think there was a knife hidden in his clothes?" Ye Lin began to guide Xiao Wang to think more, especially about the murder weapon. The murder weapon was not found at the scene. If the murderer did not take it away, then maybe they had to expand the search area.

The hot water in his hands was still emitting warmth, and with the presence of two policemen, his heart gradually calmed down a lot, and some scenes began to slowly be recalled from his memory.

"I remember when he came down, he was holding a takeaway bag in his hand. I didn't know what was inside. I thought he had delivered the wrong thing or something." Xiao Wang recalled.

Ye Lin narrowed his eyes slightly, "Can you describe to us how big this takeout bag is?"

Xiao Wang thought about it, put down the cup, and gestured, "It's this long, a big bag, a bit like the ones we send barbecue with skewers."

Ye Lin roughly compared it and found that this length was more than enough to hold a dagger. The murderer might have put the weapon in a takeaway bag and took it away.

"Very good, this detail is very helpful to us. What else do you remember? What else is wrong?"

"It's gone. I only saw it for about ten seconds. There's really not much left." Xiao Wang really couldn't remember anything. It was such a short time, and it was about to rain, so there was really nothing left.

"Okay, you take a rest first. Don't worry, it's safe here." Ye Lin comforted Xiao Wang and got out of the car.

"Xiao Sun, Qi Shan, come with me to check the surveillance footage and see how much was captured." Ye Lin called Sun Jinghua and Qi Shan and instructed.

Jingyuan’s community is similar to Lanyuan next door, with the same nature and not much surveillance.

Ye Lin checked the surveillance footage from the security guard's office, and what was shown on the screen was similar to what Xiao Wang had described. Two minutes before he arrived, an electric bike stopped downstairs of Unit 2, and a delivery boy walked into the corridor carrying a takeaway bag.

2 minutes later, Xiao Wang arrived.

The murderer's appearance could not be seen in the entire surveillance footage. All that could be confirmed was that he was holding the takeout bag when he went up and when he came down.

Sun Jinghua and Qi Shan checked a lot of surveillance cameras along the way, but it was useless. After leaving the community, the road became even darker. Several deliverymen were mixed together, and it was impossible to tell who they were.

Helpless, Ye Lin could only give up. At least he knew that the case was indeed committed by the man dressed as a delivery man.

Now all we have to do is find him.

When Ye Lin returned to the scene, Xiao Wang suddenly got out of the car and shouted to Ye Lin:

"lead!"

"No need to call the leader, what's wrong, what did you think of?"

"I did think of it, but it happened the day before yesterday. I don't know if it matters." Xiao Wang said weakly.

"Oh, tell me about it." Ye Lin encouraged. There was only one day between the day before yesterday and today, so it was hard to say whether there was any connection.

"Actually, it's like this. I delivered food to this deceased person the day before yesterday, and I even complained about it to everyone in the group."

"You see, at that time, someone even mentioned whether this woman would be killed like the previous one."

Xiao Wang called up the chat history of the WeChat group and showed it to Ye Lin.

The more Ye Lin looked at her, the gloomier his expression became. He asked in a low voice, "When the female victim was killed last time, was there anyone in this group who complained about her?"

"Yes, there was one who took a selfie with a knife at someone's door."

The more Ye Lin listened, the more shocked he became. The victims in both cases were single women, and from the deliveryman's perspective, they were all fairy-like types. Moreover, both cases had been discussed in this group through messages before the incidents.

He had a hunch that this group might be the key to solving the case.

"Xiao Sun, join this group and then collect information with Qi Shan. I suspect the murderer is in this group." Ye Lin called Sun Jinghua over and instructed.

Sun Jinghua took it and looked at it, his face immediately turned bitter, "Captain Ye, there are too many people here, more than 300 people in the group, and none of them are real-name registered. It will take us a long time to find them."

Ye Lin looked down and was shocked. Damn, there really were more than 300 people.

"Are all of you riders from a certain group? Do you know each other?" Ye Lin could only turn to Xiao Wang for help.

Xiao Wang smiled awkwardly, "Boss, I was invited to this group by someone else. There are people who work as takeout deliverymen and some who used to work as takeout deliverymen. It's just a place for everyone to chat, complain and show off. I don't know who they are specifically."

Ye Lin felt overwhelmed after hearing this. After thinking for a while, he said, "Let's go back and discuss this. Xiao Sun, you join the group first."

Sun Jinghua scanned the code swiftly and successfully lurked in the delivery man group.

At this time, Qi Shan pulled Ye Lin aside and said a few words to him behind everyone's back.

Ye Lin shook his head after hearing this, "It's too dangerous."

"Captain Ye, I can do it, and this is the fastest way to find the person." Qi Shan was very persistent.

Ye Lin looked back at the building behind him and nodded slowly, "Okay, let's go back and deploy it."

......

On the afternoon of June 6, a new tenant moved into Unit 22, Building 8, District 401 of Lanyuan. She was a single girl with short hair and looked capable.

Building 8 is located at the innermost part of the community and is quite remote.

In a place like Lanyuan Jingyuan, it is normal for tenants to move in and out, and no one will pay special attention to how many other people have moved into the same community at this time.

After this girl moved in, she rarely went out. When she really had to go out, she would cover her face tightly with a sun hat so that you couldn't see what she looked like.

But since she moved in a few days ago, the neighbors upstairs and downstairs have discovered that this girl is just a bitch - she acts like a bitch!

And just do it with the delivery man.

As soon as it was noon, evening and midnight, she started ordering takeout. She didn't know how she could finish so much food by herself. Anyway, she could always see several delivery guys delivering the food.
