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

Sun Jinghua stood up first. "I checked the data of the deceased's takeout and express delivery. The deceased ordered 35 takeout orders in the past month, basically one order a day, using both the E-commerce and Tuan platforms. There were 16 express deliveries in total, almost one every two days."

"So many?" The number surprised Ye Lin. He had only seen several garbage bags in the room that day, but he didn't expect that the girl could order so many.

"Captain Ye, this is not the most bizarre thing. Look at her comments." Sun Jinghua shook his head helplessly and said, "35 takeout orders, 5 bad reviews for the merchants, 10 bad reviews for the delivery boys, and complaints against 2 delivery boys."

"This, basically half of them are negative reviews?" Qi Shan calculated in disbelief.

"Yes, this is just for takeout, and the express delivery is almost the same. She has basically complained about several couriers delivering in this area." Sun Jinghua added.

"This girl, who is single, dares to make fun of everyone like this? What's going on in her mind?" Ye Lin was speechless.

If you have a background and family, it's okay for you to do this, and people won't dare to mess with you.

You are a single girl, this is obviously an invitation for others to take revenge on you.

"Sister Shanshan, where are you?"

"Captain Ye, I went to the property management of the community to take a look. Several cleaning ladies and security guards know her. Because she is so difficult to deal with, she is very likely to complain. They complain about the security guards not sweeping the floor cleanly because they are looking at their phones. Anyway, the property management staff don't have a good impression of her."

With the previous takeout and express delivery data, Ye Lin was not surprised to hear this. He continued:

"Everyone has basically understood the circumstances of the case. There are two questions here: First, how did the murderer make the deceased open the door without any worries? Second, what was the murderer's motive for killing?"

"Based on the situation at the scene, there was no loss of property, so it is unlikely that he was seeking money. Given the deceased's popularity, I think it is more likely that he was killed in revenge. And given the frequency with which the deceased ordered takeout and couriers, he would not have been suspicious of them. So we will first investigate the takeout drivers and couriers who have been given bad reviews and complaints, as well as the property staff with whom we had quarrels, to see if they have time to commit the crime."

"Sister Shanshan, help Xiaosun. I'll go find Chief Li to get the mediation records of the original police call to see who was the one who quarreled with the deceased and caused the police to call."

......

On the morning of June 6, accompanied by Chief Li, Ye Lin met the delivery man who had quarreled with Zhang Liqin and called the police. He was a delivery man from a certain regiment and was wearing a yellow delivery uniform, which was the standard uniform of the regiment.

The delivery man is called Meng Xianmin, a middle-aged man in his forties, 1 meters tall and thin. His face is tanned from delivering food for a long time. He has an ordinary appearance and the look of an honest man.

Meng Xianmin looked unhappy about being called by the police station, but he did not dare to get angry. He just kept urging them to hurry up and release him before 11 o'clock, as he still had to go to collect orders during lunch time.

Ye Lin handed over a cigarette as usual. The cigarette opened the way and everything became easier to talk about.

Sure enough, Meng Xianmin's expression relaxed a lot after he took the cigarette.

They work in the delivery business. When they have orders, they are exhausted. When they don't, they are bored. They light a cigarette occasionally, not only to refresh themselves, but also to pass the time.

"I'm from the Criminal Investigation Brigade of Xishan Branch. My last name is Ye." Ye Lin introduced himself.

"Criminal investigation?" Meng Xianmin put down his hand that was lighting the cigarette. He knew that criminal investigation was not a police station. It would only appear when there was a big case. He didn't want to get into trouble with the law.

"Comrade police, I'm just a delivery man. What do I have to do with criminal investigation?" Meng Xianmin said speechlessly.

"Last month, on May 5, did you have an argument with a female customer, and then the female customer called the police?"

"From Lanyuan District 3."

Meng Xianmin showed no expression when he first heard this, but when he heard about Lanyuan District 3, an angry look immediately appeared on his face.

"You said that bitch, she deserved to be scolded. My scolding her was light." Meng Xianmin's emotions suddenly flared up.

"I get angry when I think about it. I arrived at the door one minute early for the order that day, but she ignored me when I knocked on the door, so I clicked 'arrived' and left it at the door. Before I left the community, she called me and said that I didn't call her and clicked 'delivered' without her permission. She said that I was overdue and wanted to file a complaint against me. She also said that the soup was spilled and asked me to pay for it."

"Then I went up to explain to her and showed her the call records. But she was so unreasonable and insisted on complaining about me like a crazy woman. She even made the complaint call in front of me."

"If a complaint is established, it will be 500 yuan. If it is my fault, I will admit it. The problem is that I have no fault."

Meng Xianmin complained a lot, and even after such a long time, it was obvious that he was still very resentful.

"So you called the police?"

"I didn't call the police. She called in front of me, so of course I refused. I wanted to explain to her and asked her not to call. But she said I bumped into her and said I was a hooligan. God, with her like that, why should I be a hooligan? Who do you think I am?"

"So you're going to kill her?"

"I was just saying that in anger. I was so angry at the time. I've seen difficult clients before, but I've never seen one as difficult as this one."

"Officer, is she here to cause trouble? You can find out if you ask around. All the deliverymen in our area know her. It's bad luck to receive an order from her."

Meng Xianmin kept talking on and on.

Ye Lin looked at him and said calmly, "She's dead."

Meng Xianmin's voice suddenly stopped, as if someone had strangled him.

His expression suddenly changed. He realized why he was asked to come today. He stopped smoking and shook his hands.

"It wasn't me. I didn't kill him. I was just saying that out of anger."

"Do you think we will believe it?" Ye Lin's face relaxed.

Meng Xianmin was so frightened that sweat suddenly broke out on his face. He said fearfully, "I, I just have a bad temper. I don't dare to kill anyone. I really don't dare."

"Where were you on the night of June 6th?" Ye Lin asked coldly.

"October 6th?"

"Yes, the day before yesterday, around ten o'clock at night, where were you?"

"The day before yesterday, the day before yesterday I was at home. It rained heavily that night and I didn't want to run. I was afraid something might happen, so I just rested at home." Meng Xianmin thought for a while and said.

"Where are the witnesses? Who can prove it?"

"This..." Meng Xianmin was almost crying, "I don't have any witnesses. I rented the house and lived there myself. Where would I get any witnesses? I really didn't kill anyone."
