A brainstorming allowed Xu Zheng to see the demeanor of these perennial front-line criminal investigation bosses, language logic, case analysis, transcript details, etc.

Xu Zheng only knew at this time that there were still many places to learn, and the samples given to him by the system were only available for special occasions.

And in the investigation of a case, in a collective action, a single person will only be a little uneducated, and it is still not enough.

Therefore, after the meeting, I waited for the time, and it was half past five in the afternoon, "I got off work early today, went back to have a good rest, and fought a tough battle tomorrow." ”

Xu Zheng didn't dare to delay for a second when he heard this, and ran away as soon as he picked up the things, leaving everyone looking at each other, only Zhang Yuqi showed a smile on the corner of his mouth, probably scared away by his own eyes.

"Alas, why did I accidentally offend this Vermilion Bird, fortunately Zhuang Qiang told me the truth, otherwise I wouldn't know how to die." Xu Zheng walked out of the gate of the detachment, glanced back, and hurried home.

As a result, she called Han Rui, she said that in Angel Supermarket, Xu Zheng hung up the phone and took a taxi to rush over.

Angel supermarket, speaking of 30 years of history, from the beginning of the small supermarket to today's 500 square meters of medium-sized supermarket, the current owner and major shareholder is Wang Nianpan's daughter-in-law, Lan Annie, about 40 years old, is the kind of petite Jiangnan girl.

But the personality reveals a fiery temper of a Northeast girl.

As soon as Xu Zheng entered, around six o'clock, it was the busiest time, and this supermarket was located in the feng shui area of the Drum Tower.

There have been countless people who wanted to buy this supermarket or buy it or replace it with a triple store, no matter how many methods they used, they couldn't do it. The government agreed, but our public security department did not agree, and the lower-level leaders agreed to do it, but the provincial political and legal committee did not agree.

It's not why, because there are no part-time workers in this supermarket, all of them are bosses and employees, and Lan Annie, who is also the store manager, only has a little more shares, and she only receives a salary of more than 4,000 yuan.

As for the first store manager, of course, it was Xu Zheng's grandmother Su Tongyun.

That's right, most of the employees in this store are the families of the martyrs in the police circle, and they are not greedy, and there are currently only two stores in total, which will no longer expand to meet the work needs of the families of the martyrs in Changming City.

"Oh, I'm coming back, I haven't seen you for a long time, I heard that your baby has made a great contribution, and there are several third-class merits, but you can give us a long face." It was Aunt Liu who spoke, she had been working here for ten years, and she had watched Xu Zheng grow up.

They are all acquaintances, Xu Zheng's childhood basically grew up here, very familiar, said hello round, saw Han Rui sorting out the shelves, took out an apple to be processed from the discount area, wiped it, and slipped to Han Rui's side after nibbling.

"Look at you like this, haven't you had another day and a night without rest, you can take it easy, don't look 10 years older than me after forty!" Han Rui said as she laid out the bucket noodles, and the ponytail at the back of her head was curled and warped.

"Hmph, I knew that Sister Xiaorui had a heart that wanted to be my sister...."

Han Ruijiao snorted, how could she, a university lecturer, not know the meaning of Xu Zheng's words, and was about to give him a good beating, when she saw Lan Annie coming over in a blink of an eye.

"Tut, it's really a couple in love, and they're reluctant to part for a minute, yes, you two hurry home, look at it, it's estimated that you've stayed up late again, hurry home and sleep." Lan Annie is not an elder at all, plus she has a baby face and loves to joke, Xu Zheng treats her as a sister.

"Sister Lan, look at what you said, we don't want to be separated from you."

"Go, go, poor mouth, your director will come in a while, and I will have to train you again, let's go."

"Sister Lan is here, he doesn't dare!"

After a while, Xu Zheng and Han Rui went home together, and their relationship seemed to come together naturally in the eyes of relatives and friends, including Xu Zheng holding Han Rui's hand, which was also so natural.

Early the next morning, after everyone arrived, Qu Hou began to assign tasks, Xu Zheng suspected that Qu Hou, the divorced deputy detachment leader, had fallen into the beauty scheme, and actually divided him into Zhang Yuqi's group, a group of four people, just right.

Xu Zheng glanced at Qu Hou with slanted eyes, no one in the group knew that he said the wrong thing yesterday, and they were all waiting to see his own good show, which was also a little fun in the boring work of handling cases, and Qu Hou was arranged today.

Four people, driving the bald man Zhuang Qiang, Zhang Yuqi and Ji Meiyue sitting in the back seat, two beautiful policemen, of course, are definitely wearing civilian clothes now.

In fact, the people of the criminal police team often wear civilian clothes, probably because they rarely face the general public.

The task they received was to find out Su Nanying's best friend in college, and after graduation, neither of them was admitted to graduate school, and her best friend got married earlier than her, and basically got married as soon as she graduated.

Xi Ying, 34 years old this year, got married after graduating at the age of 22, what is unexpected is that she was originally a student of Changming Institute of Technology, and when she graduated, she married Xiang Zheng, who was 34 years old when she was an associate professor at the time, and also caused a sensation in two schools.

Therefore, after getting Xi Ying's basic information, Zhang Yuqi took the initiative to ask Ying to stop this task.

In the face of this kind of wife who may be a murderer, Zhang Yuqi and they didn't dare to blatantly touch the row, and the objects they contacted were the community where Xi Ying's family was located, as well as the property guaranteed by the community.

After Xi Ying got married, she taught her husband and children at home, and she didn't start to go to work until the past two or three years, and the work was very simple, an accountant's assistant, Xu Zheng, and they also successfully inquired about Xi Ying's work after taking out their police officer ID.

After understanding Xi Ying's work, everyone had to investigate Xi Ying's husband Xiang Zheng.

Changming University is a book, Xiang Zheng's level is a third-level professor, a professor of economic management, and he has his own scientific research group, as if the project fund is about 100 million, just by virtue of Zhang Yuqi's identity, if there is no evidence, only conjecture, he can't enter the school to investigate Xiang Zheng directly.

Plus, the murderer must not be let know that he is being investigated at the moment!

Therefore, everyone investigated several professors at the same time as the school was obscure through students and teachers, and all of them used the method of hiring experts in the name of outside companies.

The roundabout inquiry, as well as the information provided by the community, barely let everyone have a general understanding of Xiang Zheng.

Back in the detachment, the other two squads also returned, and looking at their appearance, they should be similar to what Xu Zheng and their team investigated.

Xu Zheng read these materials again, and Su Nanying was the worst of the four little sisters in the school dormitory.

Her husband drives an online car-hailing service, Xi Ying's husband is a professor, and the other two are lawyers and a small leader of the Liuhe District Government.

Xu Zheng focused on the lawyer's file, Yan Gang, 36 years old, has a law firm in the city, an elite person with a successful career, and over the years, he has gone from a small lawyer to a famous divorce case, and now he is working for several large companies, not to mention this work ability.

Yan Gang is not a Changming person, he is a rural person from other provinces, and he can have today, all because of his hard work step by step, at present, there is no bad record on this file, and there are many similarities with Zhang Yuqi's mental profile.

For these people, there is no conclusive evidence, and they really can't even be interrogated, first, they are startled, and second, the people who can do this series of cases can't pry their mouths open just by interrogation.

Therefore, at present, the only way in front of the task force is to find evidence.
