In September, the autumn breeze always makes people think about the past. Not long after Teacher's Day, Liu Yi also returned home from the hospital to recuperate for a few days, and Liu Yi wanted to take advantage of Gao Xiaoqing's return to school to adjust.

Shortly after Liu Yi was discharged from the hospital, Gao Xiaoqing received an email from her at a foreign university, and the school had an art seminar, and Gao Xiaoqing needed to represent the college to attend. Gao Xiaoqing didn't want to go either, but there was no way, this seminar was very important for the school.

Liu Yi touched the gloves that Gao Xiaoqing bought for him before leaving, and he couldn't help but feel a tingling in his heart. After Shen Xiao left Liu Yi, this was the first time that Liu Yi felt like this. Liu Yi picked up his mobile phone and began to look at the photos taken with Gao Xiaoqing in the past few days. Gao Xiaoqing's smile is so bright, like a ray of sunshine shining on her heart in autumn, so warm and comfortable.

At this moment, Liu Yi's mobile phone rang, it was Wang Jianguo. Liu Yi hadn't seen Wang Jianguo for a long time, and during this time, Wang Jianguo called Liu Yi once, saying that there was something in the bureau, and he would contact Liu Yi when it was over.

"Brother Wang? What's wrong? Liu Yi felt that his vacation was coming to an end.

"Xiao Liu, let's come to the bureau first!" Wang Jianguo's words were brief, and he hung up the phone after speaking. After Liu Yi hung up the phone, he immediately put on his clothes and rushed to the Southern District Bureau. When Liu Yi arrived at the Southern District Bureau, Wang Jianguo and Xu Wei were already waiting for him at the door.

"Brother Wang, viagra, why are you all waiting here?"

"You're a VIP! Of course we'll have to wait here! Xu Wei said with a smile.

"Xiaowei, don't make trouble, hurry up and go in!" The three of them came to the conference room, and there was no one else in the conference room, only Zhang Jie and Ma Boxing.

"Long time no see!" Liu Yi smiled and said hello to Zhang Jie and the others, and after a few people greeted each other, Wang Jianguo walked to the front and said: "Don't talk nonsense, Hu Ju let us form an old case team!" As soon as Wang Jianguo's voice fell, Wang Lan pushed the door and entered, "I'm sorry, Wang Group, I'm late!" ”

Wang Lan hurriedly sat next to Xu Wei, and then listened to Wang Jianguo, "Actually, there is nothing?" You don't have to be so nervous, you can take a look at the information in front of you.

Liu Yi found that there were three different case materials in the file bag in front of him, and Liu Yi suddenly found that one of them was Shen Xiao's case back then. Liu Yi tried his best to stay calm and directly turned over the case.

"The director means that we will solve them one by one, and limit the detection of these old cases by the end of the year. This time it's a little different, these people from the North District Bureau are also detecting, don't lose the face of our South District Bureau! Liu Yi felt that this task seemed to be heavier than before.

"Master, isn't this a game of people! Some of these cases are more than ten years apart, and there are few clues, how can they be solved? Xu Wei was lying on the table, his eyes straight, and he looked lazy.

"Xu Wei, correct your attitude, don't chirp crookedly here." Wang Jianguo severely criticized Xu Wei.

"Wang Group, I heard about this case, but I was still studying at the police academy at the time and did not participate in the investigation, and my roommate and I still studied it privately." Zhang Jie said.

"Okay, let me reiterate that several of you and I have temporarily formed an old case team to solve these cases in the file. Everyone's 100% spirit! Let Xiaowei introduce this case to you again. After Wang Jianguo finished speaking, he handed the information in his hand to Xu Wei. Due to the difficulty of the case, Wang Jianguo specially applied for Liu Yi to join the old case team. Because Liu Yi helped the Southern District Bureau solve the case many times, the Hu Bureau finally agreed to Liu Yi to help solve the case.

The case occurred on 25 December 1997. It was Christmas, which was supposed to be a festive day, and a male corpse was found in the outdoor toilet of a high school in City C. It was discovered by a schoolgirl who, after using the toilet, accidentally saw a foot under the manure tank.

The girl was also curious, she looked closely, and the girl was so frightened that she ran out of the toilet, shouting that she had killed someone, killed someone. When the girls' homeroom teacher learned of the situation, she went to the outdoor girls' toilet with the principal.

After calling the police, the local police arrived and pulled the man's body up from the manure tank. Wang Jianguo was also present at the time, and the man was naked, and his limbs were in a state of laxity before the body was pulled up.

After the autopsy, the man was about 1.65 meters tall, slightly thin, and had no other injuries on his body except for small abrasions on the joints of his hands and feet. The cause of death was a cold-related disorder of the pulmonary circulatory system. This is very similar to a case abroad.

Through the verification of the man's identity, Cong Zhijun, male, 32 years old, single, school store owner. After the police investigated the people who came into contact with Cong Zhijun, they came up with the following clues.

Cong Zhijun was on duty at the school after the Christmas party on the evening of December 25, when the girls' dormitory was repaired because of the toilet maintenance, and they had to get an outdoor toilet if they wanted to go to the toilet. Cong Zhijun remained in the office on duty until after 12 midnight and did not return to the teacher's dormitory, where Cong Zhijun lived alone and was not accompanied by other male teachers.

The distance between the teacher's dormitory building and the girls' dormitory was less than 50 meters, and the police initially judged that Cong Zhijun might have been trapped and finally frozen to death in the manure tank when he peeped at the girls going to the toilet at night. But the case consists of many doubts.

First, the entrances of the teachers' dormitory building and the women's dormitory building were monitored, but Cong Zhijun was not found to come out.

Second, there were a total of seven girls who came out to the toilet that night, and the police interrogated each female classmate, but there was no result, and it was normal to open it from the time calculation, and there was a teacher on duty at the door of the girls' dormitory, and she did not find anything abnormal.

Third, Cong Zhijun conducted a voyeur, but the manure tank was narrow and inaccessible, how did he get in? The police also pulled him up from a urinal by smashing it.

Fourth, the police conducted a comprehensive search of the girls' dormitory and the teachers' dormitory, and did not find any murder weapons or poisons, and the girls' dormitory all gave evidence to each other, and no one saw Cong Zhijun at night.

Liu Yi read the confessions of seven students again, and each student had witnesses, "Brother Wang, almost all the girls in the school lived in the school at that time, and there were six people in each dormitory, and four of them did not reach six. Liu Yijiang pointed to the school information and said.

"Xiao Liu, do you suspect these girls in the dormitory?"

Liu nodded, "There are four people in bedroom 302, three people in bedroom 306 and three people in bedroom 312." According to the distribution map of the school's dormitories, the two dormitories 306 and 312 are facing each other, and they are the location of the mountain. ”

"Xiao Liu, what do you mean?"

"I'm just guessing, it's either suicide or homicide, if it's an accident, I think such a narrow mouth may not be able to accommodate him!"

"Liu Yi, you mean, it may be a student partnership? And cover each other? Zhang Jie said.

"It's possible, the height of the third floor can be used to get down with tools, and it should be that the police didn't have favorable evidence at that time, so this case became an unsolved case!" Liu Yi knocked on the table a few times and said.

"I was there at the time, and I thought it was a student, but we didn't find any clues in the dormitory, no evidence! And there are protective fences from the first floor to the third floor. ”

According to the materials, Cong Zhijun is kind and liked by students, and often helps students move things at school. It's a warm-hearted person.,Usually eat and live in the teacher's dormitory.,There's no bad habits.。 It's incomprehensible! Zhang Jie touched his head a few times.

"Master, it's been more than ten years, is this school still there?" Xu Wei clearly has no hope for this case.

"It's still there, and it's not the same as before, except that the inside and outside of the school building have been painted!" Wang Jianguo projected a photo of the school on the big screen. Liu Yi found that the old and new school buildings were nothing more than painted on the original basis, and there was no change in the structure.

"Brother Wang, if there is no change inside and outside, then we are still very good to investigate! The point is that these suspicious female students in the dormitory do not know where they are now. Liu Yi sighed, if you can't even see a human figure, let alone find someone.

"During this time, the North and South Bureaus sorted out the information of these female students back then, and the three dormitories added up to a total of ten people, a large number of people!" Wang Jianguo also knew that the investigation of this case would be relatively difficult.

"Brother Wang, judging from the data, there are a total of 4 people who stayed in City C, namely Chen Xiaoyan, the head of the dormitory of bedroom 304. Wang Shuang and Li Ziqi in bedroom 306, and Wang Rui, the head of bedroom in bedroom 312.

"I've been in touch with the current principal and have found a few homeroom teachers." Wang Jianguo said.

"That's good! Are they here today? Liu Yi asked.

"They're all here, but they're all going to have to wait until the end of work. Chen Xiaoyan's homeroom teacher is a male teacher, named Wang Baoguo, 52 years old this year, who stayed at the school to teach. Wang Shuang and Li Ziqi are classmates, and the head teacher is called Liu Shiya, 45 years old, who stayed at the school to teach. Wang Rui's homeroom teacher is Zhao Hanmei, 48 years old, who has been transferred to another school to teach. Zhang Jie read the teacher's information again.

"The person who can have direct contact with the students is the dormitory aunt!" Xu Wei suddenly mentioned.

"It's a pity that the aunt in the dormitory died of illness last year, and now in addition to teachers and students, there is another person who can contact the case is Cong Zhijun's fiancée." Liu Yi pointed to Cong Zhijun's information and said.

Xu Wei came up, and there was indeed a person named Fang Xiaoyun in Cong Zhijun's information. Xu Wei tilted his head and asked, "Master, can you still find this person?" ”

Wang Jianguo shook his head, "After Cong Zhijun died, Fang Xiaoyun disappeared like air. We have yet to find her whereabouts. ”

"Master, there are two possibilities, it may be that you have absconded in fear of crime, or you may have been killed. However, it is less likely that they will abscond. The probability of being killed is higher, and it may be the murderer. Xu Wei analyzed. Liu Yi added: "Evacuation is also possible! ”

Wang Jianguo looked at his watch, it was already eleven o'clock at noon, "Let's take a rest first!" Have lunch, and in the afternoon let's go to the scene to have a look. After Wang Jianguo finished speaking, Xu Wei immediately stood up, stretched his waist and said, "Have you eaten?" Hungry! ”

"You! The mud can't be glued on the wall, and it's more urgent to eat than a monkey! Xu Wei touched his head and said with a smile.

Wang Jianguo shook his head, and at this moment, suddenly a Wang Jianguo received a phone call, "Hello, is it Team Leader Wang?" ”

"You are?"

"I'm Fang Xiaoyun!"
