Our group rushed downstairs in a hurry. Perhaps the group of male students who were causing trouble were so scared when they saw so many policemen appear that they quickly climbed back over the wall of the boys' dormitory. At this time, there were only two people left downstairs in the girls' dormitory, Li Yifeng, who caught Wu Yifan.
When Li Yifeng saw us coming, he immediately said eagerly as if to take credit: "I just followed a few classmates to watch the fun, but who knew that this kid was hiding in the shadows in the corner? Fortunately, one of the sharp-eyed classmates found him and we arrested him."
While Li Yifeng was talking, I looked down at Wu Yifan who was caught by him. I saw that there were still some scars on Wu Yifan's face. It seemed that he had just had a fierce fight with the group of boys. When he saw us, he immediately lowered his head and did not dare to look us in the eye. It was obvious that Wu Yifan was definitely hiding something from us!
As we approached, Bai Longfei got straight to the point and asked, "Tell me, why are you here so late at night instead of sleeping at home?"
Wu Yifan never dared to look up at us, and whispered, "I just heard that there was another murder in the school, so I came to see the excitement."
"Really? How did you know that?"
"I found out when my classmate sent me a text message. Does that mean it's illegal for me to come back to watch the fun?" Wu Yifan said, and suddenly his tone became righteous again, as if he was very right at this moment.
Bai Longfei suddenly widened his eyes and said angrily, "You are lying! You clearly sneaked out an hour ago, and this murder happened at most half an hour ago. Do you have the ability to predict the future?"
When Bai Longfei said this, Wu Yifan was immediately confused, and asked in a trembling voice: "How did you know?"
"That's none of your business, Lao Zhao. Take him back and interrogate him thoroughly this time. If you can't get any information out of him, don't let him go. I wonder how long he can keep his mouth shut!"
Old Zhao couldn't hold back any longer. After all, it would be a good thing for him if the case could be resolved as soon as possible. So he took people to take Wu Yifan away. Li Yifeng said angrily, "Did you kill Xiaolei? Why did you do this?"
As he spoke, Li Yifeng could not help but punch Wu Yifan twice again. Lao Zhao and others hurried forward to stop him and took Wu Yifan away.
After Lao Zhao's men took Wu Yifan away, Lao Zhao and Bai Longfei returned to the girls' dormitory again and continued to interrogate the roommates of the deceased. However, I did not leave. I stood in the open space between the boys' dormitory and the girls' dormitory with Lin Yingxue, staring carefully at the girls' dormitory building in front of me and fell into deep thought.
Now I won’t talk about how the murderer suddenly disappeared, but just talk about what the murderer needs to do if he wants to leave here.
The female dormitory building only has guardrails on the first floor, but not on the second floor. That is to say, if you want to escape from here, the only way is to go to the second floor, because the guardrail on the first floor is a natural ladder. Otherwise, you can only rely on the rope that Li Sha used in the white building. But I have also carefully looked at this building and did not find any ropes. That is to say, the murderer can only escape from here through the dormitory window on the second floor.
In fact, it was a mistake for me to let the police officers monitor here before. Once the lights in the dormitory building dimmed, the walls of this old and somewhat blackened dormitory building could not be seen at all. Even if someone climbed over the wall, as long as no sound was made, it would not be easy for them to be seen.
More importantly, I have asked the dormitory manager before, and the doors of several uninhabited dormitories on the second floor of the girls' dormitory building are all locked, and the keys are in the hands of the dormitory manager, the security guard, and the people from the Academic Affairs Office. If the murderer wants to leave through these rooms, he must have the keys, otherwise he will not be able to escape from this dormitory building.
I told Lin Yingxue my thoughts, and she nodded and said, "You are right. Do you think the murderer is the dormitory manager of the girls' dormitory, or the security guard who opened the door? Because only they have the key to escape from the dormitory. And if the murderer is the dormitory manager, she doesn't need to escape at all. No one will suspect her if she stays."
I nodded and said, "This is what I have always wanted to say. The murderer is either Li Sha, who pretended to be a student in a dormitory in this building and got up in the middle of the night to commit the crime. Or it is someone else who wants to frame Li Sha. I think we will have the answer tomorrow."
Lin Yingxue and I stayed downstairs for a while, chatting and smoking a few cigarettes. After Ding Yang and the others brought the body downstairs and prepared to leave, we returned to our respective dormitories in the dormitory building and prepared to rest early. We would talk about it tomorrow.
After I returned to the dormitory, Bai Longfei said that he had rested enough and asked me to go to sleep and he would just keep an eye on it. However, I shook my head and said, "No need. The murderer will not commit crimes again today. Rest assured. If there are no clues tomorrow, the murderer is likely to have committed the crime in the morgue of the laboratory building. We must focus on investigating there tomorrow."
Bai Longfei nodded and began to rest. I took out the campus ghost story book and looked at it. I turned to the only page about the morgue and read it carefully.
This story is called "Mirror in the Morgue". It tells the story of a girl who decided to stay in the morgue for a night in order to prove that she is brave. But when she arrived at the morgue, the dark environment and the gloomy atmosphere brought by the corpses made her gradually begin to get scared. Finally, in order to give herself courage, the girl found a mirror and sang to herself in the mirror all night.
At dawn the next day, the girl came out of the morgue, showing off her courage and telling her classmates about her experience last night. The classmates stared at her in fear and told her a shocking news!
There are no mirrors in the morgue!
This story is relatively new to me. When I saw it, I felt a little awkward looking in the mirror. Now, if the murderer is going to use this story as material for his next murder, what should he do? After all, at the end of the story, the girl did not encounter any trouble.
As I was thinking, I fell asleep unknowingly. When I woke up again, it was already past nine in the morning. The students had already gone out for class, and the entire dormitory building had become much quieter.
Bai Longfei was not in the dormitory. He must have gotten up early to follow up and investigate the case. I tidied up a little and went downstairs to have breakfast with Lin Yingxue. Her arm injury had not healed completely yet, so I had to take care of her a little more.
Sure enough, Lin Yingxue was still in her dormitory, but she was not sleeping at this time. Instead, she was sitting on a chair looking at the students' books. When she saw me come in, she went to get a basin of water, washed up, and prepared to go out to buy some food.
Lin Yingxue got up early. She also knew some of the information that Bai Longfei had investigated this morning. Lao Zhao had people interrogate Wu Yifan all night yesterday, and even called his father, who worked as a security guard at the Normal University, to interrogate him together with his father, but they didn't get any information out of him. However, they found something intriguing in Wu Yifan's pocket.
A condom!
It is absolutely normal for this kind of thing to appear in the pocket of a college student, but if it appears in the pocket of a high school student, it is a bit strange. At least in my opinion, it is definitely an unusual thing.
When Wu Yifan's father saw the condom, he almost fainted from anger. He grabbed Wu Yifan and beat him up, asking him what was going on. However, Wu Yifan seemed to be determined and refused to admit that the condom was his. He also refused to say what he was doing at school last night.
I never expected what Lin Yingxue said, and Lin Yingxue blushed a little and said, "Later, Lao Zhao asked Ding Yang to check whether the two deceased had been violated before their death, but no signs of violation were found, so Wu Yifan's rape and murder are not established."
I nodded and said, "That being said, Wu Yifan was able to come to school before the murder yesterday. Even if he was not the murderer, being able to come to school at that time definitely meant he had some kind of relationship with the murderer. I think this relationship should be related to the condom."
Lin Yingxue and I were alone in the dormitory talking about condoms. Not only was Lin Yingxue innocent, but I was also embarrassed. Lin Yingxue immediately changed the subject and asked, "Do you think Wu Yifan is not the murderer?"
"He shouldn't be. He doesn't have the means and shrewdness of the murderer in this case. It's just that there is definitely some connection between him and the murderer. In other words, he is just a scapegoat used by the murderer to get rid of suspicion."
At this point, I continued to ask, "What about the school? Are there any students who have moved into this dormitory recently or in the past few days?"
Lin Yingxue shook her head and said, "No, the students who live here have been living here since they first came to school. No new students have been found. In addition, the dean of studies had his staff work overtime to carefully investigate all the female students living on campus overnight. Their identities and backgrounds are all clean, and no one can be linked to Li Sha."
This news is bad news for me. I sighed. Since Lin Yingxue had packed up, I was ready to leave with her. But at this moment, Lin Yingxue suddenly said, "But it seems that a transfer student came to the school today and was assigned to Li Sha's former class. It is said that it is a girl and seems to be planning to stay here. More importantly, the hairstyle of this girl seems to be exactly the same as the description of the girl who witnessed the outline of the murderer when the deceased Xiaolei died!"
