"What clues, tell me about it." Shen Mingyu hurriedly asked.

"The forensic staff just extracted two shoe prints behind the chair where Liu Qiwei was sitting, which happened to be formed by standing behind the chair, and it is very likely that they are the shoe prints of the murderer, and the forensic staff said that the shoe size is about 37 yards."

"Okay, I'll ask about shoe size later, but I still have doubts, the threatening letter was sent to Ning Lin, so why didn't the murderer start with Ning Lin first? Instead, she started with her roommates. ”

"Could it be that the murderer wants to force Ning Lin to come out and admit the incident in the threatening letter?"

"Sure enough, I still have to know what that thing is, I'll try to ask later." Shen Mingyu replied.

Han Sicheng nudged him and motioned for him to continue asking the girls. Shen Mingyu returned to the 603 dormitory and continued the previous inquiry, this time answering Rui Yi,

"I got out of the dormitory at about 9 o'clock, and I slept a little late on the weekend today, because I knew that Sister Qiwei was going to live broadcast in the afternoon, so I planned to go to the city center with my boyfriend for a day, and come back at night, but my boyfriend's subject has not been completed, and I can't leave for the time being, and I can't go through until noon, I had to go over alone, and I took the 31 bus, and I still have a record of scanning the code to take the bus, because on the weekend, there are a lot of people in the car, and the road is also very congested, I sat for more than 40 minutes to get to the city center, Then I went to the shopping mall, because I was alone the whole time, and no one helped me prove it, and I didn't come back until Wen Qiao called me. ”

"Okay, Xiao Rui, thank you for your cooperation." Shen Mingyu said.

"Then let's talk about it, yesterday the tutor assigned an experimental task, but the time was too tight to finish it, I thought that it would be easy to go over early today and finish the weekend, I also went out at about half past eight, went to the cafeteria for breakfast, about 9 o'clock, I went to the laboratory, there was a senior brother at that time, but he left when he was close to dinner at noon, and then I was alone there to do the experiment, no one can prove it, and finally Wen Qiao called me back, I should be the first to arrive." Wang Xiaomeng replied.

"Xiaomeng, I know, well done." In the end, only Ning Lin was left, she opened her mouth, but she didn't speak, and after a while, she slowly answered,

"I was the last one out of the dormitory today, it was about 9:20 o'clock, when I went out, Sister Qiwei also asked me to help tighten the curtains, I usually like to go around the area, because what happened a few days ago I was very stressed, I want to be alone to relax, I went to the nearby park after breakfast, about 10 o'clock, walked for an hour or so, I went to the park pavilion to rest, there were a lot of aunts and uncles singing in the pavilion, they should be able to prove it for me, and then about 12 o'clock, I walked out of the park to the nearby supermarket, I usually like to go to the supermarket, buy some things and go back to school, I just happened to get to the operation when I received a call from Wen Qiao, so I immediately went back. ”

"Xiao Lin, you're doing a great job, thank you for your help." Shen Mingyu felt that he couldn't ask Ning Lin about that matter in front of the other girls, so he could only wait until he had the opportunity to be alone and ask in detail.

"Oh, by the way, there's another question, what are your shoe sizes, can you tell me."

"Brother Shen, do you want to help me buy shoes, then I'll have to pick the expensive ones." Lan Yingxue teased.

"Uh...... This is for the sake of investigation, and I will talk about buying shoes later. Several girls also laughed at this time, relieving the previous lifeless atmosphere.

Shen Mingyu opened the memo on his mobile phone and wrote down the shoe size of each girl respectively, Lan Yingxue 38, Rui Yi 39, Zhang Muru 35, Ning Lin 36, Wang Xiaomeng 37, only Wang Xiaomeng is size 37 shoes, could it be her, Shen Mingyu thought in his heart.

At this time, Han Sicheng walked in and motioned for Shen Mingyu to come out first.

"How's that going, is there any progress?" Shen Mingyu replied: "I asked all of them about their movements today, and found that at the time of the crime, almost none of them had an alibi, and only Wang Xiaomeng's shoe size was 37. Han Sicheng frowned and said: "This incident is a bit tricky, there are no useful clues now, we can only continue to collect information, I have communicated with the school before, try to suppress this matter, otherwise the students will hear that there is a homicide in the dormitory, it will definitely cause a commotion, and then the situation will not be under our control, we need to race against time, the school said that there is no empty dormitory for the time being, and the 601 dormitory is also from other places, and now we can only clean up the abandoned dormitory. Let them stay here for the time being. ”

"What about the police officers who are responsible for protecting them and me?" Shen Mingyu asked.

"I told them to rest in the dormitory management room on the 6th floor, there happened to be a bed there, as for you, why don't you go to the abandoned dormitory and live with them." Han Sicheng teased with a slight smile.

"You BYD, Han Sicheng wants me to die, right?" Shen Mingyu scolded. But after scolding, he didn't seem to think of a better way, fortunately, the abandoned dormitory has an extra balcony than other dormitories, and he can barely sleep if he makes a mattress.

Han Sicheng said: "Then you can sleep on the balcony, it's good." After speaking, he pulled Shen Mingyu to the 603 dormitory, Han Sicheng and the girls said: "Students, now because of the incident, 601 can't live for the time being, now I can only let you live in the abandoned dormitory first, and be patient for a few days, our police officers will protect your safety, they are in the dormitory management room on the 6th floor before, what can call them, as for Comrade Shen Mingyu, let him sleep on the balcony to protect you, can you see, otherwise he has nowhere to go." After saying that, Han Sicheng looked at Shen Mingyu and smiled evilly.

"Brother Shen is from the Public Security Bureau, so he shouldn't do anything, right? Looking at Brother Shen, he doesn't look like that kind of person, he doesn't dare, hahahaha. Several girls discussed happily, Shen Mingyu's face was red, but he had to pretend to be very sophisticated, he said: "Brother is a person who has seen the world, not so frivolous, you can put ten thousand hearts." Han Sicheng saw Shen Mingyu come out to make a statement, so he patted him on the shoulder,

"It's up to you." Although the words were brief, Shen Mingyu felt the sense of responsibility in the words, and he nodded.

Shen Mingyu and the girls have three chapters: first, when you want to go to the toilet, ask if there is anyone and make sure that the girls are not changing clothes or anything.

Second, you must wear clothes at all times, do not take them off, and change in the bath. Third, there are things that everyone can discuss together, and they can't decide privately.

In this way, Shen Mingyu and five girls lived in an abandoned dormitory and named it 600. In the evening, Shen Mingyu was invited to the dormitory from the balcony, Wen Qiao also came over to liven up the atmosphere, a few people chatted, Shen Mingyu tried to make the girls laugh, in fact, his heart is complicated, the girl who is in the prime of his youth suddenly said that he left and left, it is still quite sentimental, on the other hand, he has the responsibility to protect these girls, therefore, what he has to do is to calm their mood first.

Late at night, Shen Mingyu suddenly heard the sound of ooh, ooh, ooh, he woke up from his sleep and found that other girls were also woken up by this sound one after another, and they were discussing.

Suddenly, Rui Yi shouted: "Yingxue is gone!" Everyone got up to look for Lan Yingxue's figure, and Shen Mingyu couldn't care about it so much, so he asked the girls to turn on the lights quickly, but the girls said that the power was usually cut off at about 12 o'clock.

Everyone took out their mobile phones and turned on the flashlights to illuminate the surroundings, but there was no trace of Lan Yingxue, and Shen Mingyu said to everyone: "You stay in the dormitory first!" I'll go to the dormitory and ask the police for help first! Everyone stayed in the dormitory according to Shen Mingyu's instructions, but suddenly heard another loud noise on the balcony, several girls were six gods at this time, and they thought that there was something strange in the dormitory, I don't know who took the lead, everyone ran outside the dormitory, and chased in the direction of Shen Mingyu.

The movement was so loud that it almost woke up the students on the 6th floor, and everyone crowded into the hallway to see what was going on.

Shen Mingyu turned around and found that something was wrong, causing a riot, and the girls of 601 didn't know where they were scattered by the crowd, Shen Mingyu didn't think much about it, rushed to the dormitory management room next to the staircase, and woke up the two police officers who were resting,

"Go over there and maintain order! Lan Yingxue is gone, I'll go find her! The two police officers ran to the corridor non-stop, but they found that it was too dark, and there was only a faint light in the corridor, so they could only take out a flashlight to illuminate the surroundings. Shen Mingyu quieted everyone while he searched for the source of the sound, and at this time, he heard the sound as if it came from the other side of the corridor.

On the other side of the corridor, it was originally intended to build 10 more dormitories on this side, but in the end it was not implemented, resulting in nothing on this side except a window at the end.

In addition, because of the new public toilets on each floor, the corridor on this side can only be reached through the other door of the public toilet, and no one usually goes to this corridor.

Shen Mingyu asked the police officer to light the flashlight forward, and everyone actually saw a person wearing blood-red high heels slowly walking towards the end of the corridor, Shen Mingyu saw that this person was wearing a pink star Kirby pajamas, and recognized it as Lan Yingxue's pajamas, but because the light was dim and he couldn't see the person's face clearly with his back to everyone, some people in the crowd recognized that this pajamas were Lan Yingxue's, and shouted loudly: "Yingxue, what are you doing, come back quickly!" ”； As if she hadn't heard, Lan Yingxue walked straight to the window, and Shen Mingyu was also shouting desperately

"Come back, Yingxue, I'm Brother Shen, it's dangerous over there!" Lan Yingxue was still indifferent, she came to the window, suddenly turned around, showed a very weird smile, and then gestured a death gesture with her fingers, and then jumped from the window.

Shen Mingyu suddenly felt bad, and pulled a police officer through the toilet and hurried to the window to check, leaving another police officer to stay and maintain order.

But the girls watched Lan Yingxue walk to the window step by step and jump down, where can they calm down, the police are almost unable to maintain order, Shen Mingyu called Han Sicheng to hurry up while running, when he ran to the window at the end of the corridor, he only found a pair of blood-red high heels, he looked under the window, and saw that on the platform on the second floor, Lan Yingxue, who was wearing pink pajamas, had fallen there.

Shen Mingyu immediately returned to the corridor and signaled the two police officers not to let anyone on the 6th floor leave, and he called Xiao Li and Xiao Liu again and asked them to hurry over from Building 8.

He rushed to the platform on the second floor, at this time there were already students who heard a loud noise and ran out to see, Xiao Li Xiaoliu blocked the scene, and asked the students to go back to the dormitory to rest, Shen Mingyu got out of the window of the corridor on the second floor, arrived at the platform, and found Lan Yingxue's body, the back of her head hit the concrete floor of the platform hard, and a large blood stain spread out from the back of her head, and there was no sign of life.

Shen Mingyu suddenly found that Lan Yingxue also had a note beside her, which actually read

"This is the second, revenge." Shen Mingyu collapsed, collapsed to the ground, and lost consciousness.

I don't know how long later, he woke up and found himself in an abandoned dormitory, surrounded by the girls of 601 and Wen Qiao.

Wen Qiao said: "Officer Li said that after you rushed down the second floor, you saw Yingxue's ......, and then fainted, are you okay?" Shen Mingyu got up and replied: "It's okay, maybe I'm too tired......" He got up and walked to the balcony, blowing the wind of the early morning, Jing unconsciously shed tears, there was a nameless fire burning in his heart, this murderer actually dared to kill in front of the police, or in this way, I must find out this person myself!

Then, he slammed his fist into the wall of the balcony, and blood immediately flowed from his knuckles. At this time, a hand behind him handed over the tissue and towel, Shen Mingyu looked back and saw that it was Wen Qiao standing behind him, Wen Qiao said: "I know how you feel in your heart, everyone is uncomfortable now, I will help you as much as possible and pull this person out of the darkness as soon as possible." ”

"Thank you, you're always so understanding." Shen Mingyu wiped away his tears and said slowly. He walked to the door of the dormitory and asked Xiao Li Xiaoliu to protect the girls in the dormitory, while he himself had to go to the second floor to check the situation and report to Han Sicheng by the way.

Han Sicheng saw Shen Mingyu coming over, and asked with concern, "

"Are you alright, a few of us just moved you to the dormitory in half a day."

"It's okay, I'm asking to get involved right away." Han Sicheng saw Shen Mingyu's resolute eyes, nodded, and said: "The deceased Lan Yingxue, female, the cause of death is that the internal organs were damaged by a strong external force and caused a lot of bleeding, and the preliminary judgment was that he fell to his death, and the time of death was within an hour, and it is now two :45. Shen Mingyu said: "I watched her fall downstairs, it was about 2 o'clock at that time, not only me, almost all the girls on the 6th floor watched her jump down, and compared a gesture of death, but I found the same note next to the corpse as Liu Qiwei's body, indicating that this was a serial murder case, and the murderer was a blatant provocation to the police, and actually killed people in front of the police." ”

"That's right, the murderer this time is very difficult, do you have any clue?"

"That's right, I suspect that the person who jumped down may not be Lan Yingxue, but the murderer pretended, she wants us to think that Lan Yingxue walked to the window and jumped down by herself, but I don't know what technique she used now, because the dormitory will be powered off at night, at that time there was only the light of a flashlight, it was very dim, not very close, and it was not clear to see the specific facial features and appearance at all, we recognized her by our pajamas."

"It makes sense, but Lan Yingxue did fall to her death, if it was the murderer in disguise, then how did she also let Lan Yingxue fall from the building in the process of jumping off the building? Could it be that Lan Yingxue jumped off the building by herself at that time, but she was intimidated or controlled? Han Sicheng asked.

"It's not clear yet, we need to look into it." Shen Mingyu replied.
