Zhang Yang walked out of the interrogation room and found that Wang Shuang was still sitting on a chair outside the interrogation room, stunned. Zhang Yang walked over and touched Wang Shuang's head and said, "Xiaoshuang, let's go home!" After speaking, he took Wang Shuang's hand and left the police station.

"Master, it seems that Zhang Yang still can't let go of Wang Shuang!" Xu Wei said.

"Hmmm! Let's go to the conference room first, and let's have an impromptu meeting. Wang Jianguo summoned all the people in the old case team, and the six of them sat in the conference room, Wang Jianguo said: "After two days of interrogation, we can say that we have unexpectedly gained a lot of clues, but it cannot be ruled out that some of these people lied." ”

"Brother Wang, I have an idea, but I need to review it specifically!" Liu Yi said.

"On the first day, we didn't get any favorable clues from the teacher's interrogation, but we knew some clues from Chen Xiaoyan. It is likely that the teacher was hiding what was happening in the school at the time. I think Chen Xiaoyan knows something, but I don't say it explicitly. When Liu Yi was alone with Chen Xiaoyan, she felt that when she mentioned Cong Zhijun, her expression was uncertain.

"Indeed, but there is no evidence that Chen Xiaoyan and Cong Zhijun have any special relationship, we need to investigate Cong Zhijun's other colleagues, and the information shows that Cong Zhijun's store at school was opened with another teacher." After Wang Jianguo finished speaking, he asked Zhang Jie to take out a dozen materials behind him.

"Master, why didn't you see this that day?" Xu Wei was a little surprised.

"I just sent it, you can take a look!" After Wang Jianguo finished speaking, he took out one of the files and said: "This file is from the General Bureau, it takes a long time, and there are still some originally, but it is in the North District Bureau. Wang Jianguo tapped the file with his hand.

"Judging from the information at this stage, Cong Zhijun is indeed a good gentleman, but his potential has been suppressed by his own rationality." Liu Yi said.

"Judging from the ratio of men to women in Mingguang Middle School, there are more girls." Zhang Jie said while reading the information.

"We have now figured out how the murderer threw the body, but I have a new question, the murderer has no scars on his body, and there is no trace of being attacked, so how did he obediently let the murderer take him away?" Wang Jianguo asked.

"Wang Group, I checked the autopsy report of that year again. The autopsy report showed that the victim had no alcohol or other narcotic substances in her body and no internal or external injuries on her body. These points are very suspicious, how can a person faint so easily? Wang Lan was thinking hard, and Liu Yi said: "It can't be acupuncture?" ”

"Liu Yi, I see if you have watched too many martial arts movies, I am giving you two palms to see if you react!" Xu Wei put on a posture of palm on the spot.

"Viagra, don't make a fuss, I'm serious. Sister Lan, is it possible to do this in traditional Chinese medicine? Liu Yishuang looked at Wang Lan.

"It's possible, it's not impossible for you to say it, but I don't know much about acupuncture, but I have a senior brother who is a Chinese medicine doctor, and we can ask him." After Wang Lan finished speaking, she was about to take out her mobile phone.

"The General Administration should still have some information, and we will go over tomorrow to take a look." Wang Jianguo said.

"That's great, you have to know more about the case so that there will be a breakthrough in the case. The rest of us can spy on a few insiders to see if they have anything to hide about it. After Liu Yi finished speaking, he picked up the information on the table again and began to read it. He felt that it was all like fate, and when the case was discovered again, all the people involved appeared in the eyes of the police.

Zhang Jie was in charge of Li Hanmei and Fang Xiaoyun, Xu Wei was in charge of Wang Shuang and Zhang Yang, and Ma Boxing then investigated the online materials of Cong Zhijun's case. Liu Yi and Wang Lan will go to the General Administration with me tomorrow. Wang Jianguo glanced at his watch, and it was already half past six in the evening.

"Master, do you want a treat?" Xu Wei said with a grin.

"A treat? I'll give you a kick, hurry up! Wang Jianguo plans to sort out these old files again to see if he can find new clues from here. After Xu Wei and the others left, Liu Yi asked: "Brother Wang, did you ignore a lot of clues in this case back then?" ”

"It's not that it's ignored that the hardware facilities of that year were not complete, and the Tianyan project has not yet been implemented. There were very few clues in our hands, and I took a lot of effort to check privately, but I found nothing. The confessions obtained are basically the same, and they have no use value at all. Wang Jianguo said.

"Cong Zhijun doesn't have any relatives in City C?" Liu Yi asked.

"After investigation, Cong Zhijun has no relatives in City C, and he is a native of other provinces who came from City A in 1994, and I asked the school at that time. The answer given by the principal was that Cong Zhijun was originally a security guard at the school, because the school was expanded once in 1996, and it was necessary to add a small store on campus to facilitate students to buy some daily necessities and food. The school made a recommendation, and finally Cong Zhijun and another security guard took over the work of the store. ”

"Another security guard?"

"Yes, there was also a security guard named Guo Dongliang at that time, 3 years younger than Cong Zhijun, also from other provinces, both of them are usually in school, but Guo Dongliang does not live in the school, but rents a house outside the school, and occasionally stays in the teacher's dormitory for one night. This information is not in our possession, but I have checked it privately, and I feel that it has no connection with Cong Zhijun's case. Wang Jianguo said as he lit a cigarette.

"Have you investigated this person?"

"The day after Cong Zhijun's death, Guo Dongliang died unexpectedly at home due to drowning."

"Drowning?"

"Yes, after the examination of Guo Dongliang's body, the blood alcohol content exceeded the standard, and more than a dozen bottles of beer were found next to the bathtub at the scene. Wang Jianguo sent a text message on his mobile phone and continued: "You can look at the details for yourself in a moment." ”

"Who called the police?" Liu Yi asked.

"It's Guo Dongliang's girlfriend, and when his girlfriend found out, Guo Dongliang was already dead."

"Did you find anything on the scene?"

"I was not present at the time, and there was no trace of the crime at the scene, which is unbelievable, and in the end I had to judge it as an accidental death." Wang Jianguo shook his head, and then vigorously extinguished the cigarette butt in the ashtray.

Liu Yi flipped through for a while, and suddenly found Guo Dongliang's old file, Liu Yi looked at it carefully, Guo Dongliang, male, 27 years old, security guard of Mingguang Middle School, used to be a security guard of Youlian Shopping Mall. No criminal record. Guo Dongliang's family is relatively well-off, and the money to open a small store was given by his father.

Liu Yi thought to himself that if he wanted to know more about Cong Zhijun, he also needed to investigate Guo Dongliang's understanding. Guo Dongliang's girlfriend's name is Qin Meili, a cram school teacher near Mingguang Middle School, and she still lives in City C.

"Brother Wang, tomorrow we need to take some time to investigate Qin Meili!" Liu Yi stood up and stretched his waist and said.

"Okay, I'll get in touch with the ponies, let's go to the main bureau tomorrow morning." Just then, Wang Jianguo received an email. After Wang Jianguo opened it, he found that it was sent by Principal Li, "At this time, the design sketch of the school's outdoor toilet? ”

"I'll see!" Liu Yi came to the front, and he was surprised to find that the pit inside the toilet was not dug by the murderer for a long time, but that the construction unit wanted to use this hole to carry out sewer transformation, but because of geological problems, it finally failed.

"Brother Wang, the hole dug by the construction unit is not very big!" Liu Yi pointed to the 50 centimeters on the sketch and said. Wang Jianguo nodded, "The murderer didn't take long in the later stage, and it was almost ten centimeters wide." As soon as Wang Jianguo finished speaking, Zhang Jie called.

"Wang Group, I found out that Fang Xiaoyun did not go to the hotel, but went directly to another place."

"Another place?" Wang Jianguo was a little surprised.

"Wang Group, the place she went to is located in a community not far from the hotel, and through verification with the property of the community, we finally determined that the name of the person she was looking for was Qin Meili!" Wang Jianguo was secretly happy in his heart.

"Xiao Zhang, well done, let's go now!" Wang Jianguo said as he got dressed and motioned for Liu Yi to prepare to go. Wang Jianguo drove for less than 20 minutes, and the two came to the location Zhang Jie said.

"Wang Group, you guys are too efficient!" Zhang Jie said with a smile.

"You're different! How long has it been up? Wang Jianguo casually lit another cigarette.

"It's been an hour or so!" Zhang Jie looked at his phone.

"Through these investigations, we can't rule out the suspicion that they have made confessions." Liu Yi said.

Wang Jianguo nodded, the three of them went upstairs together, after the three of them entered the elevator, Zhang Jie pressed the elevator on the seventeenth floor, Liu Yi smiled and said, "Okay!" It's getting better and better! ”

"It's all a trivial matter, how can I stay in the group after I can't do it!" Zhang Jie said with a smile.

It didn't take long for the elevator to stop at its location on the seventeenth floor. The three of them walked out of the elevator, Zhang Jie signaled to the left, Wang Jianguo walked up and knocked on the door twice, and someone inside immediately responded, "Who?" ”

After Wang Jianguo revealed his identity, the door opened, and it was Qin Meili who opened the door. Wang Jianguo and Xu Wei showed their documents, and Qin Meili nodded, "Then you guys come into the house and talk!" ”

After Wang Jianguo and the three of them came in, Fang Xiaoyun was a little surprised, but then calmed down again. Wang Jianguo asked, "Do you all know each other?" ”

"Yes, we're actually best friends!" Qin Meili took Fang Xiaoyun's arm and said with a smile.

"Originally, we wanted to ask you something about Guo Dongliang tomorrow, but it seems that we can only do it today!" After Wang Jianguo finished speaking, he observed the surroundings, Qin Meimei's house was about 140 square meters, with an attic.

"You're following me?" Fang Xiaoyun reacted.

"I'm sorry, the case is complicated, and we can't help it, I hope you can actively cooperate!" Although Fang Xiaoyun was a little angry, in order to prove her innocence, she could only actively cooperate with the police investigation.

Wang Jianguo first asked Qin Meili: "How long have you known Guo Dongliang?" ”

"It's been a year!" Qin Meili was trying to remember.

"You were the one who called the police at that time, does Guo Dongliang have any enemies?" Wang Jianguo asked.

"You asked back then! Guo Dongliang is an otaku, he doesn't have a big deal to do, he usually doesn't go out much, where does the enemy come from. Every day is a two-point one-line life, school, home, school home! Qin Meili actually felt that Guo Dongliang was a boring man.

"After Cong Zhijun's death, did Guo Dongliang say anything to you?" After Wang Jianguo asked, Qin Meimei's face turned blue instantly, and Liu Yi was secretly happy in his heart, knowing what Qin Meili must know.

"I, I don't remember......" Qin Meili flatly denied.
