Yi Qing took a sip of water and said, "After this Shi Mingkai was arrested, he originally confessed very well. But after the case reached the pre-trial stage, he kept shouting that he was wronged, saying that he did not rape Jiang Lina, let alone kill her. All previous confessions were refuted. ”

"Then how did the Public Security Bureau determine that Shi Mingkai was raped and murdered?" Xiao Wei asked curiously.

"I just took the case, and I also learned about it briefly. At that time, someone confirmed that he was seen going out of the dormitory with Jiang Lina, and later ran back in a panic. Then there are Shi Mingkai's fingerprints and footprints extracted in many places in the laboratory, including Jiang Lina's body, and there are traces of being beaten. ”

After a pause, Yi Qing continued: "Of course, there are some other details and evidence, such as Shi Mingkai has a slight scratch on his body, and I don't understand it to you." The most important thing is that he has a motive for committing the crime, because Jiang Lina is pregnant and is forcing Shi Mingkai to marry her. ”

"Pregnant?" Xiao Wei and Lin Guohong were both surprised: "Does Jiang Lina's family know?"

Yi Qing replied: "I shouldn't know, this is Shi Mingkai's confession." A teacher made a female student's belly at school bigger, and once it gets out, it is likely that Shi Mingkai's job will not be guaranteed. ”

After Yi Qing finished speaking, he fell into deep thought, and it was obvious that this case made him scratch his head.

Yi Qing secretly thought: Shi Mingkai first confessed that Shi Mingkai asked Jiang Lina out again that day, and originally wanted to discuss how to deal with it. As a result, as soon as she saw Jiang Lina, she couldn't help but want to be affectionate, who knew that Jiang Lina had to ask Shi Mingkai to make her words clear first, and Shi Mingkai had to overlord the bow. Afterwards, Jiang Lina threatened Shi Mingkai to denounce him, and the two had an argument, and Shi Mingkai strangled Jiang Lina to death by mistake during the scuffle.

Yi Qing knows that there is no direct evidence in this case, so the confession is extremely important. Now Shi Mingkai retracted his confession in the pre-trial stage, and the case was returned to the serious crime team.

This was the first difficult case he had since he became the captain of the serious crime team.

Xiao Wei looked at Yi Qing and was silent, thinking that Yi Qing was unwilling to inquire about the case by himself.

So, he explained: "Brother Yi Qing, it's not that I have any thoughts about the case, but I know some of the circumstances, and I don't know if it's useful to you?"

"Oh?" Yi Qing was surprised when he heard Xiao Wei's words: "What's the situation, let's talk about it, maybe it's very helpful." ”

Xiao Wei said: "That's right, on the day of the crime, I saw Shi Mingkai and Jiang Lina, and they were in the experimental building. ”

"What?" Yi Qing suddenly became interested when he heard this: "You tell me in detail." ”

So, Xiao Wei told Yi Qing everything he saw that night.

After listening to this, Yi Qing asked: "You and Guohong have both seen it, when Shi Mingkai jumped off the building and escaped, Jiang Lina was still alive?"

Xiao Wei replied affirmatively: "Yes, we all saw it with our own eyes, Jiang Lina is still looking down from the window." Guo Hong and I still wondered, obviously I saw Jiang Lina, why did the later people die?"

Yi Qing said: "The information you provided is very important, and it may make the case take a new turn. In this case, I need you to go to the public security bureau to give testimony, that is, to record a confession, okay?"

Lin Guohong looked at Xiao Wei with some embarrassment: "Do you still have to go to the Public Security Bureau?" ”

Yi Qing laughed: "What's there to be afraid of going to the Public Security Bureau, it's very simple to record a confession." And we'll keep the witnesses confidential. By the way, are you all eighteen years old?"

Xiao Wei and Lin Guohong both shook their heads.

"In that case, I have to ask your teacher Situ to accompany you. How about it, I will do the work of your Situ teacher. Yi Qing said very seriously.

Looking at Yi Qing's sincere eyes, Xiao Wei nodded and agreed, although he was still a little inexplicably worried. Lin Guohong saw that Xiao Wei agreed, and she nodded in agreement.

Without further ado, in order not to affect Xiao Wei's class, the time was set for Saturday morning. For this reason, Yi Qing also called Situ Chunyan and asked her not to go home on weekends.

Situ Chunyan also learned of this situation, and she also did work for Xiao Wei and Lin Guohong, pointing out that it is the duty of every citizen to cooperate with the public security organs in handling the case and testifying in accordance with the law. She encouraged both of them to be brave and face it.

With Situ Chunyan's positive work, Xiao Wei and Lin Guohong have a lot of confidence in their hearts.

On Saturday morning, Xiao Wei, Lin Guohong and Situ Chunyan quietly came to the Public Security Bureau to record a confession, especially the details in it, which Yi Qing asked very carefully.

With the testimony of Xiao Wei and Lin Guohong, Shi Mingkai's case has a new situation. Yi Qing reported the situation to the director, and the bureau attached great importance to it and readjusted the investigation thinking.

As a result, the task force re-stationed in Pengcheng No. 1 Middle School and re-investigated the relevant personnel of the school.

Based on Shi Mingkai's confession and the testimony of Xiao Wei and Lin Guohong, Yi Qing focused his investigation on the last person who entered the experimental building.

Although Shi Mingkai, Xiao Wei, and Lin Guohong did not see who this person was, judging from the details of that person entering the building and turning on the lights, this person must be someone from the school.

So, Yi Qing listed all the male personnel in the school and checked them one by one.

This move by the Public Security Bureau broke the peace of the campus. The case that has been gradually forgotten by people has returned to the limelight and has become the hottest topic in everyone's mouth.

In order to improve office efficiency, it is also to minimize the disruption to the normal working order of the school. Yi Qing's Serious Crime Team set up a temporary office in the school's security department.

The school has set aside two offices for the work of the Serious Crime Squad, and has also arranged for Liu Zhengyi, chief of the security section, to fully cooperate with the work of the public security organs.

For a time, the security department became the focus of attention of all teachers and students in the school.

Whoever was called away by the task force, how long they stayed, and who came back, would make people whisper behind their backs for a long time.

There are also some men who may not be very peaceful, after returning from the task force, they were given a good training by their wives by pulling their ears, and remember not to mess with flowers and grass outside, otherwise the consequences will be very serious.

It may be that it has been more than two months since the incident, and it is very difficult to investigate the personnel movement time.

In the past two days, the special case team has checked all the designated personnel, but still no obvious clues have been found.

This is the first time that Yi Qing has been the main person in charge of investigating a major case, and who knew that he would encounter such a difficult bone to gnaw. Yi Qing, who was in high spirits when he came like this, was a little discouraged.

I went through the investigation materials and the list of people again and again, but I didn't have a clue.

Bewildered.

After thinking about it, he decided to talk to Xiao Wei again carefully.
