"Okay, no matter who he is, he will finish the case at hand first." Lao Xu roared impatiently, thinking of this, he was also aggrieved, but there was no way, from the moment he and Jiang Dong chose to stay in the bureau, they were ready to be so unwelcome.

"Do you know whose son Du Yu is?" A few people had just been stopped by Lao Xu, and they were not discussing the reward, Wang Xi suddenly asked everyone loudly.

"Yes, what is the origin of this Du Yu, why is the news on the Internet making such a fuss?" Lao Xu waved his hand impatiently, and turned back to ask Wang Xi, who was investigating Du Yu's interpersonal relationship and background.

"Hehe, don't say it, this Du Yu is really a bit of a source, you will definitely not think of it." Wang Xi said mysteriously.

"First of all, whose son is it? New to leadership? Wang Zhi looked puzzled, and he asked blankly, already tired.

"It's not ~ how is it possible!" Wang Xi rolled his eyes.

"This Du Yu, twenty-six years old this year, was persuaded by the school to return home because he had never been to class much in his junior year. He is the son of Wu Lianchi's uncle Du Jianguo, who used to be a principal and is now in the school supplies business! Wang Xi looked at the other three people who obviously had a bit of a puzzled expression on their faces and said.

"So what?" Several people were a little confused.

"You forgot his father? When he was the principal, what did Satsuki say? Wang Xi asked everyone excitedly.

Until everyone suddenly realized, she continued: "It's not like no one knows the inside story of this matter now, and no one is willing to stand up, there must be something wrong here."

And if the black car serial murder case four years ago is really his son, maybe we can find the force behind this former principal who has been in business through Du Yu. Wang Xi said clearly.

Since Jiang Dong, who played a leading role in the team, fell into a coma, the three young people have grown rapidly, and they are also bold and innovative in their thinking, unlike before, only waiting for the leader to ask before they can say their ideas.

"Seeing that his son is about to go to prison, how can Du Jianguo find a way to find someone to get his son out, right?" Han Shuo touched his chin, he was even looking forward to the picture of arresting Du Yu and going to prison.

"How's your check? In addition to the six women who died four years ago, the remaining twelve people who were screened out were all right with Du Yu's time? After listening to Wang Xi's analysis, everyone was full of motivation again, and Lao Xu got up and walked to Wang Zhi, looking at the pile of missing and murdered women in Wang Zhi's hand.

"Uncle Xu, this Du Yu has been wandering for a year since he was sent home in his junior year, and he lived with his family this year. Later, I entered Du Jianguo's company, and the name I found showed that he was the company's after-sales manager.

In the past few years, his registered residence is still his parents' house, but according to my investigation, most of his activities in the past three years have been around City C and City L, and the clear scope of his activities in the past three years has not been determined so quickly. Wang Xi said embarrassedly.

"It's okay, I'll send a message to the housing registry office, asking them to check the housing registered in the name of Du Yu's family, as well as the information on the rented house. We should have a detailed copy of the information tomorrow. Han Shuo quickly operated the computer.

"Brother Han, bring up a copy of the vehicle record." Wang Xi said to Han Shuo.

"Yes, it has to be." Han Shuo nodded and replied, these materials with real-name registration are easy to investigate, but they are already at this point, and the information will not be sent until tomorrow when they go to work.

"Okay, everyone finish up the things at hand, go back early today to rest, early tomorrow morning, Wang Xi stays, Han Shuo and Wang Zhi, let's go to City C together, and meet this Du Yu who has just woken up from danger." Lao Xu closed the information in his hand, stood up and spoke.

Everyone was stretching their waists, and in short, with the suspects suspected to be investigated, the progress of this afternoon was much more than what they had gained in the previous three weeks of busyness.

……

Early the next morning, on the way to the examination room, Wu Shuai kept following Li Yifan closely, and kept talking about what Li Yifan promised last night.

"Remember to send me the answer to your phone as soon as you finish answering the paper, you can't help but check it for too long, it's too late." Wu Shuai raised the mobile phone in his hand and said to Li Yifan. Along the way, he's said this no less than twenty times.

"Yes." Li Yifan held his forehead speechlessly.

He was almost annoyed by Wu Shuai all the way, I was really afraid that Wu Shuai would be so babbling, the classmates along the way knew that they were going to pass the answer to him, and they didn't know how last night, so they agreed to him in a daze.

"Hehe, Yifan, it's good that you agreed first, otherwise the person who was so annoyed by him today would have been me." Zhang Rui had an expression of 'fortunately not me', and Li Yifan could only shake his head helplessly.

Also, how did he forget, Wu Shuai is the only one in their dormitory who 'temporarily cramms' every time he takes the exam, plus yesterday Lao Tan said that he was going out to collect style, how could Wu Shuai still have the heart to read the book!

At the same time as Li Yifan's exam, Han Shuo, Lao Xu and others had already arrived at the police station in Yingnan Town, Jiao Ting's hometown, south of City C. This will be compared with the local police officers about Du Yu and the only clues left by the black car murderer four years ago.

"I am the police officer in charge of Du Yu's case, my surname is Zhao, you can call me Lao Zhao. After we received your call yesterday afternoon, we took Du Yu's DNA and blood early this morning and sent it to the city to compare it with the blood and sebum residue left by the murderer on a deceased person four years ago, and the results will come out in the afternoon at the earliest, and the DNA results are estimated to come out until tomorrow morning. Lao Zhao shook hands with Xu Youliang and explained the current situation.

"I heard that Du Yu woke up last night, can we go over and see him today?" Lao Xu looked at the confession that the police officer made to Jiao Ting yesterday and asked.

"I'm afraid this won't work, we have contacted the city hospital, and Du Yu will not be able to leave the intensive care unit at noon today." Lao Zhao shook his head in embarrassment.

"Can you tell me about Du Yu's daily life trajectory?" Han Shuo asked.

"Xiao He, you and this comrade will explain." Lao Zhao called a small police officer next to him, and handed it to Xu Youliang to keep an eye on, and the two of them went to sit next to them.

Du Yu, the usual source of life is mainly to help his father deliver and after-sales work in the campus appliance store in the city, to put it bluntly, he is mainly looking for someone to pull things in, and he pulls the installer to install it with the delivery person.

Their family's business has been very big in recent years, and Du Yu is also a standard rich second generation, although he has only been in our Yingnan Town for more than two months, but he drives around the town every day when he has nothing to do, and the owners of several big barbecue restaurants here know him. Xiao He handed a confession to Han Shuo while talking about Du Yu's daily life. [.]
