The female dormitory has five floors, with 12 dormitories on each floor. At that time, there were too many dormitory students, so four bunk beds were placed in each dormitory. Liu Yi pushed open the doors of the two bedrooms 306 and 312. The girls' dormitory is clean and tidy.

Liu Yi recalled that when he lived in the dormitory, it was dirty and messy, and he couldn't get off his feet. In Wang Jianguo's eyes, except for a simple renovation of the interior, nothing else has changed. Li Guangxu said with a smile: "In the past few years, the school has been well organized, there used to be eight students here, and now it is equipped with four students." ”

Wang Jianguo nodded, and Liu Yi walked near the window of the bedroom at this time, and he found that a protective fence had been installed on the outside of the window. Liu Yi asked, "Principal Li, when was the protective fence installed?" ”

"It was only installed on the third and fourth floors last year, and it was only pressed to the second floor before." Liu Yi opened the window and looked out.

Zhang Jie pointed to the curtain and said, "Wang Group, back then, students could still use the curtain to climb to the second floor, and then go down the protective railing." ”

"Yes, I simulated it back then. But it takes a lot of arm strength to do it, do you suspect it's a schoolgirl?"

"If Cong Zhijun doesn't go out of school often, there will basically be no enemies outside the society. He spends most of his time at school, and the only people he comes into contact with are teachers and students, so it is more likely that the murderer will be in school. After Liu Yi finished speaking, Wang Jianguo began to recall the scene of the year, and the police almost turned the entire school upside down, because of the delay in the students' learning progress, and later had to stop the investigation.

"We did interrogate the vast majority of students and teachers back then, but it didn't work well and we didn't find any favorable leads." Wang Jianguo actually blamed himself in his heart.

"Brother Wang, the principal of the year was called Hou Yaojie, did you find anything unusual when you interrogated him?" Liu Yi said.

Wang Jianguo shook his head and said: "Decent people speak more rigorously, and they don't find any suspicions. Liu Yi recalled the transcript he had read before, and literally Hou Yaojie did not answer anything directly, these words were more like prevaricating the police. Hou Yaojie died of illness, and now there is no way to confront him face to face.

"Now we're going to reorganize the case to see if that's the case, and then we're going to start looking at the suspects one by one." After Liu Yi finished speaking, everyone closed the door of bedroom 312.

"First of all, this student has a personal grudge with Cong Zhijun, but not once, it may be after many times before he will be carried away. The second point is that after Cong Zhijun returned to the classroom dormitory alone that night, he then saw the murderer. The first scene should be the teacher's dormitory. Third, the murderer chose to commit the crime in the early morning, when most of the students were resting and basically did not stay up late to study. And there's plenty of time. Liu Yi walked to the window and glanced at Zhang Jie and said.

"There's a lot of time, we're running at half past five, but it's going to be canceled in the winter. Breakfast is served in the cafeteria at six o'clock. Lee Kwang Wook said. Liu Yi has read these materials in the old case materials, but Li Guangxu's active cooperation with the police still makes Liu Yi very pleased.

"It was impossible to go down from here with curtains without being detected, and it was winter when the windows were supposed to be heated." Liu Yi looked back at Li Guangxu and said.

"The little brother was right to say that the school building in our school is not well sealed, and we all press plastic sheeting on the windows in the winter." Li Guangxu's answer refuted Zhang Jie's conjecture.

"Xiao Liu, how do you think the murderer got out?" Wang Jianguo didn't come up with it either.

"Brother Wang, the aunt in the dormitory also passed away due to illness, so it is impossible to confirm whether there were any female classmates who secretly ran out at that time. When I got up that night to go to the toilet, I needed to register with the aunt in the dormitory, and the information showed that the girl on the list did not contradict Cong Zhijun during the interrogation, and only Chen Xiaoyan was related to Cong Zhijun. It is also possible that the murderer did not enter the girls' dormitory. Liu Yi said.

"Didn't get into the girls' dormitory? What does that mean? Xu Wei said.

"Viagra, don't worry! We can guess that the murderer has been hiding in the outdoor toilet......" Before Liu Yi finished speaking, Xu Wei said: "Liu Yi, I will check the bed at that time, and who is not sure can know at a glance."

"Viagra, how did you avoid checking your dorm room when you were in school? And then there's the fact that she's probably not in school, but outside of school! Obviously, Liu Yi's spearhead is directed at Wang Rui.

"You mean Wang Rui?" Xu Wei said in surprise.

If what Chen Xiaoyan said was true, on the day of the Christmas party, Wang Ruiyu and Cong Zhijun had another quarrel, causing Wang Rui to be punished by the school and taken home for education that night. It is very likely that she will go back to school in the early morning to find trouble with Cong Zhijun, but there is one thing I can't figure out, how does Wang Rui accurately grasp Cong Zhijun's every move? Zhang Jie swept himself into the quagmire of thinking again.

"Wang Rui is from this city, and his home is fifteen minutes away from the school, so it is still possible to come to the school in the early morning to commit murder, but the time is indeed very punctual. If the murderer is Wang Rui, then there is a possibility that there are people with her in the school. In addition, Wang Rui's confession said that she did not leave the house all night, because the door was locked by her father all the time, which we need to confirm again. Liu Yi knocked on the bed in the bedroom and said.

"Could it be Wang Shuang?" Wang Jianguo said.

"It's very possible, but all this is inconclusive for the time being, after all, I haven't seen Wang Rui himself!" Liu Yi said.

At this time, several police officers and excavation personnel who had just arrived were already digging behind the outdoor toilet. Everything will wait for the results of the excavation. Wang Jianguo glanced at his watch, and there was not much time left in the morning.

"Let's go to the teacher's dormitory again!" After Wang Jianguo finished speaking, he took Liu and a few others to the teacher's dormitory. The teacher's dormitory is not large, with a total of three floors, six rooms on each floor, and Cong Zhijun's location at that time was in a room on the inner side of the first floor. At that time, there were not many teachers living in the school, so Cong Zhijun lived alone in a room inside.

"No one dared to live in this house, after all, Cong Zhijun used to live in it, and then it became a warehouse. Usually install some tools. Lee Kwang Wook said as he took out the key to open the door. The door opened, and a puff of dust scattered from the frame.

Li Guangxu waved a few times, "Please come in, everything has changed, I don't know if Team Leader Wang still remembers?" Wang Jianguo saw that the house was full of cleaning tools and some cultural utensils such as notebooks. Liu Yi looked around, there were two windows in this room, both of which were equipped with protective fences.

"Remember! At that time, the bed was by the window! By the way, I remember that there was a table next to the door, and a curtain hung on the bed. Wang Jianguo walked to the corner of the wall and continued: "There is also a large iron cabinet here, and there are some boxes and food bags for drinks next to it. ”

Li Guangxu admired Wang Jianguo's memory very much. Liu Yi thought to himself, there should be four teachers living in this house, but at that time, he should have taken care of Cong Zhijun to give him a room.

"What did Xiao Liu find? I wasn't there, but I just looked at the photos and the things in front of me. Cong Zhijun's accommodation environment is still good, but the bed is blocked by a curtain, which is a bit strange, generally only the girl's dormitory will use this thing, Cong Zhijun should not need it if he lives alone! Liu Yi spread out his hands and glanced at Xu Wei.

"Yes! What does a big man do with things? Xu Wei squinted his eyes and said.

"Cong Zhijun should be a cautious person, and he should have a lot of secrets in his heart!"

"That's right! I remembered that the information said that there were a lot of wooden handmade empty boxes under Cong Zhijun's bed, large and small!" Zhang Jie hurriedly continued Liu Yi's words.

"Yes, people who generally like boxes more often have more things hidden in their hearts. These boxes are like their hearts! Liu Yi explained.

"What do you mean? Liu Yi, you can be more detailed! Xu Wei's eyes straightened, and he looked at Liu Yi directly.

That is to say, our inner world also has capacity, and once we accumulate too many secrets, we need something to carry it. The human heart is like a big box, but that's only the spiritual realm. If you have a long-term backlog and will suffer from depression, then these boxes are in a sense a tool for Cong Zhijun to share secrets. After Liu Yi explained again, Xu Wei seemed to have a clue.

Wang Jianguo nodded and said, "When I came in, except for the bed, which was a little messy, the other places can be said to be spotless. ”

"Cong Zhijun should pay attention to his appearance in normal times, and he must clean the place where he lives often." As soon as Liu Yi finished speaking, a criminal policeman ran in from outside the door and said breathlessly: "Wang Group, Wang Group, dig it up, you go and take a look!" ”

Several people immediately rushed to the scene, and when they were still 200 meters away from the outdoor toilet, Liu Yi and others faintly smelled a foul smell of feces.

"This smells!" Xu Wei muttered and immediately covered his nose with his hand. Liu Yi saw that the workers at the scene had towels around their noses and were sweating profusely, and in order to save time in handling cases, these excavation workers were also working hard.

Wang Jianguo walked up to several policemen and excavation workers and said with a smile: "It's hard work, drink some water!" I saw Li Guangxu coming over from not far away with two large bags of mineral water.

"Come on, come on, drink some water! It's going to heat up! Lee Kwang Wook said as he twisted the cap of the bottle and handed it to the people who had worked hard for two hours.

As soon as Liu walked to the excavation position, he was surprised to find that this part was buried again, and they heard one of the excavators say that after digging for a short time, the shovel suddenly touched a hard object, and when he looked closely, it turned out to be an iron plate, about five centimeters thick. Bad feces have been deposited under the iron plate. Liu Yi found that this position was not visible at all from above because of the angle.

"Xiao Liu, the murderer should have entered from here!" Wang Jianguo lit a cigarette and tried to drown out the stench of the feces.

"Yes, it seems that the murderer has put a lot of effort into digging this tunnel, and it is definitely not done on a whim, if you want to dig a tunnel, it still takes time, and it can't be discovered." Liu Yi carefully rubbed the width of the hole.

"It should be possible to go down alone." Zhang Jie also leaned over at this time.

"Yes, Cong Zhijun is thin and medium-sized, so he should be able to enter. The abrasions on the joints of the limbs on the corpse should have touched the sides of the tunnel while hauling the corpse. Liu Yi touched the soil on both sides of the tunnel, and it was indeed hard.

"Xiao Liu, let's go back first, and leave it to Xiao Wei here!" After Wang Jianguo snuffed out the cigarette butts, he walked out of Mingguang Middle School with Liu Yi. Liu Yi felt that the case was advancing, and the truth would definitely slowly surface.
