Li Ji looked at Xie Qing, who raised his chin, suggesting that he should speak for himself.

Li Ke spoke frankly, "Captain, the three of us have produced three lists, but none of the evidence is very reliable."

Captain Huang said, "Okay, tell me, I'll learn from you."

Li Ke took the A4 paper in his hand and pointed to a name with two stars. "This person often hangs out in the Wangjiang neighborhood, and occasionally goes to the Qingjiang Park area. He is 35 years old, which fits the characteristics of a serial killer. Several drivers said that this person has a bad temper and gets angry easily. I I don't think he necessarily killed anyone, but we can ask him some more questions."

Huang Zhenyi wiped his chin, "Very good, Li Ji, what do you think?"

Li Ji has been working for more than a year and is much more tactful than Li Ke. "Captain, I selected a few people I think are suspicious based on the analysis of Brother Du and Brother Liu. I also selected the one that Li Ke selected, mainly because I got the inspiration from the case in the old city. The murderer has a bad temper, so he stabbed the victim so many times."

He supplemented Li Ke's statement.

"That's good too." Huang Zhenyi smiled, "Where's Xiao Xie?"

Xie Qing felt a lump in her heart. The two idiots spoke so perfunctorily, how could she explain it? A crushing statement?

How could that work!?

Xie Qing said, "Captain Huang, I'm just joining in the fun and calling out the troops."

Huang Zhenyi pointed at her with his index finger, "You are a little kid, but you have a lot of ideas. They asked you to come because you have more ideas than them, right? Hurry up!"

The two idiots nodded together.

Li Ke said, "That's right, if you tell us, we can learn from you."

This silly girl is hopeless.

Xie Qing thought to herself, okay, I'm a forensic doctor, and you're criminal police. We have different promotion channels, so just tell us.

She repeated her analysis and said at the end, "Captain Huang, my idea is too subjective, and it is not much different from calling out soldiers and generals. Just listen to it and think about it as an expansion of your thinking."

Huang Zhenyi frowned and sat down, rubbing his chin with his big hand. He hadn't shaved for about two days, and the stubble was two or three millimeters. Every time he shaved, it made a "swish" sound.

Li Ji and Li Ke looked at him eagerly, hoping that he could give a clear instruction.

After a minute or two, Huang Zhenyi said, "My reason tells me that it is a bit suspenseful to follow Xiao Xie's investigation method, but psychologically I think it makes sense. We can give it a try." At this point, he tapped the table and said, "I will go find Lao Li and Lao Liu and let them take you to check these seven people."

Huang Zhenyi gave face to the four people selected, two of whom were veteran detectives, but it was easy to arouse the disgust of the veteran detectives.

Xie Qing immediately said, "Captain Huang, why don't I talk to my master and let the three of us go? There's only seven of us and not much work."

"The three of you?" Huang Zhenyi shook his head. "No, no."

Li Ji understood Xie Qing and said, "Don't worry, Captain. We will definitely not make any trouble."

Li Ke nodded heavily. "Don't worry, Captain!"

Huang Zhenyi was a shrewd man. How could he not understand the three guys' thoughts? He said, "Tsk tsk," All right, you must be careful. If anything goes wrong, you will be held responsible."

He warned Li Ji and went to his independent office.

Li Ji showed his muscles and lowered his voice, "Great, maybe this case depends on us."

Li Ke jumped slightly, "I feel the same way."

Xie Qing supported her forehead, "Where do you get this confidence?"

"Of course you gave it to me." Li Ke hugged her arm, "Didn't you see that Captain Huang said that we can check according to your list?"

Xie Qing said seriously, "You can be confident, but you must also be prepared to get nothing."

"Okay, don't worry." Li Ke pulled her out, "Actually, I think what you said is even less reliable than what we said."

Li Ji laughed, "Haha", although he didn't agree, but his attitude was already very obvious.

Xie Qing breathed a sigh of relief, but she was still a little unconvinced - she is a forensic doctor and rarely does prosography, but the prototyping she did is very accurate.

…

The police station is in Fengshan District. The old city is to its northwest, also called Feng’an District. It’s too far to ride a bicycle, so the three of them took the bus.

Li Ji’s family lives in the old city, and he is very familiar with the area. He made a route plan, and the three of them went to the neighborhood committee in order. They went to seven households before 5 p.m.

Among the seven people, three of them have living parents. The reason why they did not write their parents as the contact person is because their parents’ family did not have a phone number, so they filled in the contact information of neighbors or brothers and sisters.

After a comprehensive understanding, the seven were reduced to four, and they are: Meng Wenkai, Zhao Weizhi, Sun Zhifeng, and Fan Xiaoshan.

Originally, it was not absolute to combine the Giant View case with the Huang Qi case, and the more than 100 people circled were also quite reluctant.

Now there are not even seven left. If the murderer is found among the four people, it is simply like luck.

For this, Xie Qing was mercilessly ridiculed by Li Ke and Li Ji.

Xie Qing was not angry. She was not a god or Sherlock Holmes, and she had never seen the murder scene. She never expected to solve the case that several police stations had failed to solve by looking at the files and doing some profiling.

Generally speaking, taxis usually change shifts near the owner's home in the morning and evening. The two drivers are probably from the same district and don't live too far away.

The three of them went to the residence of one of the car owners based on the principle that since they were already here, they might as well do what they should do.

The owner's surname was Chang, and his home was in Jiazi Hutong. The driver Meng Wenkai worked the night shift and usually took over at the entrance of the hutong.

The three of them were lucky. Before they reached Jiazi Hutong, they saw a red Xiali driving over. Looking at the license plate, it was the one driven by Meng Wenkai.

Xie Qing asked, "Is Li Ji going home? If not, we can take a taxi back."

Li Ji hesitated.

Li Ke said, "You are not Dayu. It is unreasonable for you to pass by your home without entering. Go back and we will talk to him."

Li Ji said, "Okay, I will go home to have dinner with my parents. If you have anything, call me." Li Ke

waved at the taxi, "Of course, I won't discuss it with you."

Li Ji left, and the taxi stopped. The window was rolled down, revealing a smiling face, "Where are you two going?"

Li Ke looked at Xie Qing hesitantly - she didn't know whether she should introduce herself.

Xie Qing opened the passenger door, "Police station."

Meng Wenkai had no reaction to the word "police station". "Which police station?"

Xie Qing said, "Fengshan District Municipal Bureau."

"Oh, a big job." Meng Wenkai's admiring eyes fell on Xie Qing's profile without any concealment. "Sister, why are you going to the Municipal Bureau? Everyone is off work."

Xie Qing said, "My classmate works in the Municipal Bureau. We made an appointment to have barbecue together in the evening."

"There are more people who eat barbecue in our old district."

"He doesn't get off work on time and doesn't go home at night. It's more convenient for us to find him."

"That's true, but... it's not very safe now. I heard that a child died a few days ago. The police suspected that it was done by a taxi driver and are investigating everywhere."

"We heard about it too. It's okay. My classmate will drive us back."

"That's fine."

"Master, do you think that child was killed by someone in your line of work?"

"It's hard to say. There are all kinds of people in our line of work."

"That's impossible. Don't you have traffic police in charge?"

"It's mainly the Transportation Bureau. You can't tell a person's heart from his face. A bad person doesn't have it written on his face, right?"

...

The two got out of the car at the door of the police station and watched Meng Wenkai disappear in the traffic.

Xie Qing said, "It's almost impossible that this man is the murderer."

Li Ke didn't understand, "Why?"

Xie Qing smiled, "Didn't you notice that he often looked at your chest through the rearview mirror? The murderer thinks highly of himself and would never do such a dirty thing."

Li Ke covered his chest with his hand and said angrily, "Rogue!"

It was time for dinner, so the two went to the cafeteria.

Captain Huang was there too. He waited for them to finish their meals and called out, "Xiao Xie, Xiao Li, there's an empty seat here."

Xie Qing and Li Ke sat down reluctantly.

Captain Huang put down his chopsticks, "How was it, did you gain anything?"

Li Ke lowered her head, "Still..."

Xie Qing interrupted her, "We have interviewed all the seven people we circled, and have ruled out four. There are still three. I will tell you the details, and Captain Huang will help us analyze them..."

The first one is Zhao Weizhi, a high school graduate, 26 years old, has a girlfriend, and is unmarried. He has been driving a taxi for six years, driving the evening bus, and the name of the emergency contact is his cousin.

His parents died of gas poisoning before his college entrance examination. Zhao Weizhi was in boarding school at the time and escaped the disaster, but it also caused him to perform poorly in the college entrance examination and he failed to even get into junior college.

The Zhao family was not rich, Zhao Weizhi did not repeat his studies, but chose to do odd jobs. During this period, he learned to drive and started driving a taxi.

People in the neighborhood committee said that Zhao Weizhi had stopped them several times. He was a warm-hearted person, talkative and cheerful, and could not be a bad person.

The second one was Sun Zhifeng, 30 years old, graduated from high school, and the emergency contact was his neighbor. His parents divorced early, his mother remarried, and he grew up with his father. His father had a tendency to mild domestic violence. After he became an adult, he often fought with his father.

He got married last year and his child just turned one year old.

The people in the neighborhood committee said that Sun Zhifeng had a bad temper and often argued with others while driving, and swearing was a common occurrence.

The third person, Fan Xiaoshan, was the car owner. He was 29 years old, married two years ago, and had a one-and-a-half-year-old child.

His father died early, and his mother raised him and his sister alone.

The people in the neighborhood committee said that his mother had a bad reputation and was suspected of being a secret prostitute, and his sister sold alcohol in a nightclub.

Fan Xiaoshan was a good student with a secondary technical school degree. After graduation, he entered a factory, but the factory was in a recession and closed down soon after.

His mother borrowed money to buy a taxi, and in order to pay off the debt, he drove it day and night until a few years ago when he paid off the debt.

After listening to Xie Qing's explanation of the three people, Captain Huang pondered for a moment and said, "They all drove late and drove red Xiali cars, but they all had no criminal records. We can't tell anything from these."

"Indeed, you can't say that just because they come from a poor family, they are suspected of murder."

"Children from such families have psychological problems to some extent, and there are not a few who commit murder."

"That's what you say, but there are also good things, right? I think it's inappropriate to put such a hat on people without any basis."

...

Several old criminal police officers sitting with Huang Zhenyi started to discuss.

Huang Zhenyi looked at Li Ke, "What do you think, Xiao Li?"

Li Ke said, "We have already investigated to this point. If we don't have more clues, I want to continue investigating."

At the critical moment, she still chose to believe Xie Qing.

Although she had no idea, Xie Qing was very happy.

The author has something to say:

Thank you, Qing, I made a mistake in the text at first - Qing is a kind of small bamboo.

So, be brave enough to admit your mistakes.
