Even if you dream about a scene often, it doesn't mean anything. But what happened in the school recently really made Song Ze puzzled.

In Song Ze's laboratory, he brought several graduate students from the physics department. Among them is a sweet-looking and shy female graduate student Bai Yuhan. In the same laboratory, there is a male graduate student Lin Yu who has a good impression of her, but Lin Yu has a dull personality and does not know how to speak. So I usually take good care of Bai Yuhan, and I have a crush in my heart.

Everyone usually studied, and there were too many things to experiment, and they didn't pay much attention to Bai Yuhan's changes. Song Ze saw Bai Yuhan in a bad mood a few times, thinking that she was worried about the subject. I kindly told her that if I don't understand the subject, I can come to the physics department at any time to ask him.

Who knew that one day, she jumped on the top floor of the laboratory. Luckily, it was early in the morning, and the physics lab was already on the far edge of the school. Usually, in addition to the students who come to do experiments, that is, a few graduate students led by Song Ze often come over.

That morning, a graduate student in the laboratory felt that there were still some questions about yesterday's topic, so he came to the laboratory early in the morning and wanted to flip through yesterday's materials. When I walked to the door of the teaching and research room, I saw Bai Yuhan lying there face down, covered in blood, and I was stunned.

When he came to his senses, he called the police in a trembling voice. The police soon arrived at the scene, cordoned off the scene, and called an ambulance. Although the floor of the laboratory is not high, Bai Yuhan is two months pregnant in her belly, and it is estimated that the time for jumping off the building is a long time, and she has bled too much, so she has not been rescued.

Lin Yuhan's parents heard the news that their daughter jumped off the building and rushed over from other places. When I arrived at the school, I heard from the police that although the floor was not high, Lin Yuhan was still two months pregnant in her belly, so she was not rescued. His father immediately scolded angrily: "It's insulting." ”

After that, let the police investigate and deal with it themselves. "We will be notified as soon as the result is available, and we will go back first. ”

took Lin Yuhan's mother and went home.

The police found out that Bai Yuhan's last call was to Lin Yu, and Lin Yu was taken away for investigation at that time. Now Lin Yu is a suspect in the case and has been restricted from acting. He didn't have the heart to go to class these days, so he stayed in the dormitory.

Lin Yu's parents came to the school and said that their son was definitely not this kind of person. Later, I found out that Lin Yu's mentor was Song Ze, so I asked Song Ze for help. said that he was not familiar with his life, and asked him to take care of Lin Yu's affairs more

Song Ze also felt that Lin Yu was not a murderer, but he could still speak in school. There is no one at the police station who knows anybody, and I don't know where the investigation has gone now. And in the last few nights, when he was in the laboratory, he could always hear someone calling him, "Teacher Song, Teacher Song." But when I turned around, I didn't see anyone.

There are two or two students in the matter, plus two helpers are missing. He's been spending more and more time in the lab lately, so he hasn't slept well these days.

Zhou Jie listened to what Song Ze said, thought about it and said:

"I know that you have always been skeptical about my monasticism, and I really haven't started to convince you. But you said that you seem to have heard someone call you, and I believe it should be related to your student Bai Yuhan. Lin Yu's side, if you have time in the afternoon, I will take you to the police station to find out. ”

"I don't have classes in the afternoon, there are still some things in the laboratory, I explained to the students, Lin Yu's matter is more urgent, or Lin Yu's matter first. ”

After Song Ze finished speaking, he called a student and asked him to take students from other laboratories to research topics in the afternoon. If you don't understand something, send him a message, and he'll reply when it's convenient for him.

Song Ze and Zhou Jie drank the coffee and ate some fruit. Look at the time, it's time for the police station to work the afternoon shift too.

Zhou Jie called a friend at the police station and talked about Bai Yuhan's case. Let him help clear it up and find the police investigating the matter to find out the progress of the case.

After waiting for a while, Zhou Jie's friend called back and said that it had been arranged for them to go to the school branch of the police station to find a policeman named Zhao Li.

After answering the phone, Zhou Jie called the waiter over, settled the bill and set off quickly.

Song Ze took Zhou Jie back to school first, went to the parking lot to pick up the car, and drove to the police station.

Bai Yuhan's case involves a school, so it is more sensitive. Not many people in the police department know about this case, only the sheriff in charge of this case knows the most details.

Zhao Li is the head of the sub-bureau's section in charge of criminal cases. Zhou Jie and Song Ze found his department and explained their intentions. Section Chief Zhao says:

"I told you above, you are the victim's teacher, and you want to know about the progress of the case. Wait with me, I'll call the Sergeant Lee in charge of this case. ”

Section Chief Zhao called Team Li, and after a while, a stout man with a full beard walked in.

Several people sat at the reception table in Section Chief Zhao's office, and Song Ze said:

"I am the teacher in charge of the laboratory, and Bai Yuhan and Lin Yu are both my students, so I want to know the specific circumstances of the case. ”

Team Li told Song Ze that there was no trace of anyone else at the scene, only Bai Yuhan's, which was currently judged to be suicide.

Bai Yuhan called Lin Yu before his death, and they asked Lin Yu to understand. Lin Yu said that Bai Yuhan told him that he was pregnant. asked Lin Yu if he could marry her, but Lin Yu refused.

Lin Yu said that Bai Yuhan told him that the child's father was a graduate student who met in an elective course, from the Department of Literature. I never saw him again after I got pregnant, and I went to the literature department to ask, but there was no such person.

Now they are investigating if there is such a person. There are other suspicious people who are also investigating, so it's not convenient to say who they are.

After telling Song Ze about the general situation of the case, he knew that he was Lin Yu's mentor, so he said to Song Ze:

"After the DNA comparison between the child and Lin Yu, if there is no parent-child relationship, then most of Lin Yu's suspicions can be ruled out. Then the focus of our future work will be on the boyfriend Bai Yuhan said. ”

Song Ze asked:

"Didn't you just say that Bai Yuhan couldn't find this person?"

Team Lee said it was. That's why they suspect that Lin Yu deliberately said this matter to divert their attention, but it is not ruled out that the person is using a fake identity.

They are investigating the surveillance of the whole school, and they are also asking students who know Bai Yuhan if they have seen her in close relationships with other men.

In the end, Team Li and Song Ze said:

"Lin Yu is not in a good state, he is very nervous, and he speaks upside down. It took a lot of effort for us to ask these questions. Since you are his guru, he must have more faith in you. You can talk to him, maybe you can ask other things and clear his name. ”
