Xu Zheng and the two returned to the office, and Zhuang Qiang also came back. He went to the school where the Huang siblings went to do some research and got the information of their former teacher five years ago.

If all the teachers of the siblings were investigated, there would be three subjects: Chinese, Mathematics, and English, with one teacher for each subject, as well as physical education, music, art, ideological and moral character, science, practice, information technology, and some dance, etc.

The school's characteristic courses generally have one teacher for each subject, so a student has at least 10 teachers.

Including the teachers at the training school, the Huang family and brother have more than 30 teachers.

Five years have passed, some teachers have resigned, and some have gone to other places... If it is not easy to investigate one by one, and if it is really the murderer, he will either continue to hide here, or go to live in other places, or even

Maybe he went abroad.

If the fire 5 years ago was really lit by the murderer knowing the consequences, and judging from the fact that he calmly avoided surveillance and escaped from the water, this person should be bold, careful, and extremely conceited, then he is very likely to still

He stayed in Changming City and even continued to work at the job he had done five years ago.

Of course, there are other possibilities. Human nature is fickle, and some people even quit their jobs after watching a movie to embark on a spontaneous journey.

Everything depends on the evidence.

The three people sat together and began to study and judge. There were more than 30 teachers. It was impossible for the three of them to check them one by one, and it was not necessary. The schools the Huang family went to were public schools, mainly because they were close to home, and their community was

School district room, Pubei District No. 1 Experimental Primary School and Middle School.

Zhuang Qiang's ability was quite good. He ran around all morning and found the teachers who the siblings had when they attended these two schools. He also found photos of these 20 teachers.

The better thing is that except for two female teachers, none of the top public school teachers at the district and county level have changed jobs. Moreover, these two female teachers changed jobs within the past two years, which narrows the scope of the investigation.

Zhuang Qiang pointed to the photos of two physical education teachers, "Look, there are so many teachers in public schools, so we can only investigate two physical education teachers. It was November when the eucalyptus occurred, and it was raining lightly. The murderer still had enough energy to run."

It's so far away, and only physical education teachers have such physical strength."

His words were a bit absolute. As long as other male teachers worked hard, it was possible. Xu Zheng glanced at the photos of these 20 teachers and realized why Zhuang Qiang said that he only needed to investigate two physical education teachers.

There are 20 teachers, 15 of whom are female. Except for the 2 physical education teachers, the remaining three male teachers are tall, short and thin. At first glance, they are not men who can run horses on their arms. As for the winter swimming of several hundred meters, just looking at the photos

It was filtered out.

"Brother Qiang, it's better to check these three male teachers more or less, and don't cause anything to happen."

Zhuang Qiang waved his hand, "The school has started. I have met all five of these male teachers. Don't worry, it is 100% impossible for the other three to be just standard weak scholars, the kind who have no power to restrain themselves."

Since Zhuang Qiang was so sure, Xu Zheng chose to believe him, "Then the public schools are currently investigating these two physical education teachers, and the training institutions are investigating all the male teachers who taught these two children five years ago."

Ji Meiyue added, "The tutors of these two children are both female teachers. Although all the evidence points to the murderer being a male, there is no substantial evidence that the murderer must be a man. Therefore, I suggest that all

The Huang siblings’ tutors who have done offline teaching should check it out.”

Xu Zheng scratched his head a little. According to what she said, female teachers in public schools are also suspects. "Let's do it, Sister Meiyue, let's screen the male teachers first. If there are no results, we will investigate the female teachers."

Ji Meiyue understood what Xu Zheng meant, and she had to search in the direction of the key suspicions. "In fact, it is basically impossible for female teachers in public schools, especially teachers of the third language, math, and English, and then the head teachers. They have already been in school."

He was busy enough, and the attack time was around 12 o'clock in the evening. In addition, it took so long to escape and he had to go to work normally the next day. If the murderer could really do it, it would be really difficult."

Zhuang Qiang also opened the scroll, "In fact, the investigators at that time also checked the teachers at the school. They believed that the murderer was likely to catch a cold and get sick in the situation at that time. Therefore, they focused on investigating the fever clinic and primary school at that time.

Clinic, and then compared it with everyone related to the Huang family, but unfortunately, nothing suspicious was found."

Xu Zheng sorted out the teacher records to be checked, and there were only about ten of them, which could be completed in two days. "This time, the three of us will act together. The key point is to observe whether they lied when taking notes for them."

And the most important thing is to keep it secret. I always feel that the murderer will never leave Changming City. He should be a very conceited person, and he even has the urge to commit suicide again.

Now I just hope that all the evil in this person's heart has not been released."

Zhuang Qiang and Ji Meiyue nodded. Some criminals often feel a sense of infinite pleasure after killing someone, and even continue to commit crimes just for this feeling. This is the case with many serial murderers.

The Huang family is the only one with this kind of murder in Changming City in five years, which is considered lucky. This is why Xu Zheng defines the murderer as a teacher. He always feels that these teachers are more humane than evil.

After sorting out the documents, the three of them were ready to set off. At this time, the other three people from the second brigade also came back. Peng Yue was more out of touch, always thinking of suppressing Xu Zheng, "Xu Zheng, you have been here for two days, and the Huang family has clues."

Is it done?"

Matching his joke-like tone, it seemed like a joke at first glance. Their team was responsible for the death of a serial woman a year ago. In fact, it was said to be a year ago, but the police didn't know if the murderer had committed suicide before.

In July this year, a eucalyptus was also incorporated into this old eucalyptus in Changming City.

But it is said that their team found a clue. Currently, Zhang Yuqi's energy is mainly cooperating with their team to investigate the murder of this woman.

Zhuang Qiang didn't usually compete with young people. He felt uncomfortable. Ji Meiyue rolled her eyes, but she wouldn't say anything to Peng Yue. Young people are competitive and it doesn't affect their work. She thought it was okay.

Xu Zheng smiled and didn't want to talk to him, but he felt that his smile was really ugly, and it affected his mood. "Peng Yue, let's take a gamble. Whoever wants to break the case will win. The loser will walk up to the Metropark Hotel and dare to

Don’t you dare?”

A meal at the Metropark Hotel costs at least 3,000 yuan, and this is without drinking. Peng Yue obviously does not have Xu Zheng’s financial resources, but his team is definitely ahead. "Okay, everyone will give you a witness. When the time comes,

, everyone orders the dishes vigorously, and they will be paid according to one month’s salary!”

Of course, the other team members started to make noises. Anyway, no matter who wins or loses, they will always get something for nothing.

But when Peng Yue saw Xu Zheng walking out so confidently, especially when Zhuang Qiang took out a document bag and waved it in front of his eyes, this obviously meant that their team also had a clue.

Peng Yue touched the mobile phone in his trouser pocket and smashed it in his mouth. In fact, his family was not short of money, but he was definitely not willing to ask for money from his family when he went to work. But for young people like them, they are all moonlighting, so he

He got entangled, hoping that Xu Zheng and the others would lose, but also hoping that they could break the Huang family's conspiracy, "Forget it, Brother Lang, are we still going out to investigate for clues this afternoon?"

The man he was talking about was Brother Lang, whose full name was Lang Shaobai. He was 34 years old. He was transferred from the Criminal Police Brigade of Gulou District. He was previously the deputy captain, earning 20 cents, and was at the deputy section level. He stayed in the second brigade for a year or two and gained some credit.

If he is transferred to other brigades, he will reach the level of captain.

In the field of criminal investigation, the path to promotion is definitely relatively narrow. Those who can reach this level have unique skills. This time, he discovered the clues about the culprit in their group.

He was also transferred here after the New Year. Xu Zheng had met him a few times before and he looked familiar.

Looking at Xu Zheng, they are also discussing this Lang Shaobai. Compared with him, Zhuang Qiang is two years younger than him, his rank is 21 cents, and his salary is one penny less than Kan. I don’t know how much credit is missing in this process.

.

"Xiao Zheng, if our Captain Zhang is promoted and transferred, Lang Shaobai and I will compete for the position of Captain of the Second Brigade, so you have to work harder!"

Xu Zheng was driving the car and was immediately amused by him, "Brother Qiang, just like you, you can tell yourself, what do you want to do if the captain gives it to you?"

Zhuang Qiang began to hesitate, "Should I do it or not?"

Ji Meiyue's eyelids twitched because the two people were talking strangely. "With your startled personality, I don't think the leaders above will use you." She said and looked at Xu Zheng again, "

If it's two or three years from now, I don't think you guys will be able to earn any more. By then, this position will definitely belong to Xu Zheng."

Xu Zheng shook his head in disbelief. The lowest level of the captain of the Second Heavy Duty Brigade must be a full-time officer. Although a fourth-level sergeant can enter the full-time department after two years, he is still a third-level superintendent.

Seeing that Xu Zheng didn't believe it, Ji Meiyue chuckled and patted Xu Zheng's driver's seat, "If you go at your current speed of committing crimes, I believe there will be no problem. Also, I dare say, if you use the technical police

If your status is promoted to the police rank, then if you add your status as an undergraduate, it will be easier to be promoted to a full-time major in two or three years."

It is true that technical officers in the police force are promoted faster than investigators, especially those projects with difficult technical barriers, such as the simulation portrait technology mastered by Xu Zheng. However, this simulation portrait technology cannot be used as evidence in court trials, but can only be used as police investigation cases.

Assistive technology, otherwise, its status in the police will be higher, and it will even become a hot profession.

Xu Zheng did not dwell on this. Anyway, he took his time and the police rank would be promoted sooner or later. In the end, the police force still looked at merit and connections. "Let's not talk about it anymore. The Pubei District No. 1 Experimental Middle School is ahead of us. Should we enter the school or go to the police station?"
Chapter completed!
