"Don't don't, don't do this, please get up." Seeing her like this, I hurriedly stepped forward to help her.

"If there's anything you can say to me, but don't go too far." I said to them.

"My father, he died so miserably......" mentioned his father's death, and this daughter almost couldn't hold back her tears.

I stepped forward and hugged her gently, comforting her: "I'm sorry, now that the person is gone, what we can do is to find out the murderer for you, for this deceased, and then hand the murderer over to the law for trial, so that your relatives can die blind." ”

"Hmm." She looked up at me and nodded vigorously.

"Then, you two must cooperate with us well, and if we ask you any questions, we must tell us in detail, understand?"

"Understood," the wife wiped away her tears, trying to calm herself. "We'll tell you everything we know."

"Very well, then please come with me, I will take you to record a confession."

After speaking, I took the two ladies to the place where the confession was recorded, and Ouyang Qian and another comrade were ready.

According to the information they told us, both women were natives of S City. Zhang Yucai's daughter, Zhang Jingyu, 25 years old this year, works at a local pharmaceutical company, and rushed over from the unit as soon as she heard the news of her father's death.

Another slightly older woman is Zhang Yucai's wife, She Jiao, who is 43 years old this year, two years younger than her husband Zhang Yucai.

She works in a yoga studio and is a yoga teacher there.

I quietly skimmed her figure, in her 40s, her figure can indeed be considered top-notch.

According to his daughter and wife, although Zhang Yucai is very strict in his education, it is only his job. On weekdays, this man is not only gentle and considerate, but also a very reasonable person. He was very kind to his daughter and wife, and he didn't even lose his temper much.

As for the repercussions in the class he taught, it was also very large. This teacher is very strict when teaching and educating people, and is meticulous with his students, no matter which class they are, never talking about feelings, never accepting red envelopes, and never going through relationships.

The math scores of the classes he taught were all one and two in the grades. There are even many parents who come to their homes in person to thank the teacher for their children's education.

Therefore, there is no such thing as a feud with any student in the class.

This came as a big surprise to us. Whether it is our initial inference or Ouyang Qian's idea, it is based on the premise that students commit crimes. But if it is impossible for the deceased to have a holiday with the students, then how can any student want to kill him?

This put us in a difficult situation for a while. But it doesn't matter, we can continue to investigate this case from other angles.

Besides, a person's personality cannot be judged only from the information obtained from the mouths of his family members or relatives, because as long as he is his own relative, he will generally praise outsiders with oil and vinegar.

So we had to find out the information from his colleagues, the school leaders, and the students in the classes he taught, and tell us in person.

Therefore, we carried out a lot of investigations, and during this period, we also sent a lot of people to visit the homes of students and colleagues. However, since it is the summer holiday season, many students and colleagues are not at home, which has caused a lot of trouble for our detection process.

After two days of investigation, we interviewed about 40 students in his class, as well as colleagues or leaders who worked with him, and from their mouths, we learned that this math teacher was indeed a decent man and gentleman, as described by his wife and daughter, and did not have a grudge against anyone in normal times.

The case is in a predicament at this point. Since there is no possibility of anyone in the school where he lives and works that is hostile to him, it means that we must re-invest the investigation work in the whole society, which is undoubtedly a very huge workload.

It even takes a long time.

If, from this point of view, it is clear that it is impossible to investigate, then we have to conduct the investigation from another angle, that is:

Employees at school during the holidays.

There are two benefits to visiting school staff during the holidays. First, we can intuitively understand what the situation was in the whole school on the day of the crime, and the murderer could only enter or leave from those places. Second: the murderer may even be hiding among these workers.

Living up to our expectations, we learned from a security guard that "during the holidays, there is only one way to enter the school, and that is the main entrance of the school." Although there was no security guard at the school gate at the time of the crime, there was a monitoring probe at the gate. ”

At the same time, another security guard at the school who was on duty in the morning told us that he had memories of seeing Zhang Yucai enter the school.

"Because I am acquaintances with Mr. Zhang, I often say hello. He was very friendly and greeted us warmly every time he saw our security guard on duty. He came to school that day, and I remember it very well, although I don't remember when it was, but I know very well that he came to school. ”

We excitedly asked the security guard at the school gate for this deadly surveillance probe. Just as we were examining the monitoring probes, we made new discoveries.

From the monitoring probe, we learned that on the morning of the incident, there were only seven people in and out of the school, including Zhang Yucai.

In addition to this math teacher, there are two girls, three boys and one boy.

But the time period when Zhang Yucai entered the school struck us as strange. He entered the school at half past eleven in the morning, and he was in a hurry to enter the school, with something in his hand.

We took a closer look at the object, and it seemed to be a small note.

However, we didn't find anything like a note on the corpse.

Moreover, during this time period, other students who had already entered had already gone out from the gate of the school.

In Zhang Yucai's time in school, didn't there be a single student in the school?
