Xu Zheng and the two returned to the office, and Zhuang Qiang also returned, he went to the school where the Huang family sisters and brothers went to investigate, and also got the information of the teacher five years ago.

If all the teachers of the siblings have to investigate, there are three subjects of language, mathematics and English, one teacher for each subject, as well as physical education, music, art, ideology and morality, science, practice, information technology, and some school-specific courses such as dance, these courses, each subject is generally one teacher, so a student has at least 10 teachers.

Counting the teachers in the training school, there must be more than 30 teachers in the Huang family. Five years have passed, some teachers have left, some have gone to other places... If it is difficult to investigate them one by one, and if he is really the murderer, he will either continue to hide here, or go to live in other places, and may even go abroad.

If the fire 5 years ago was really lit by the murderer knowing the consequences, and judging from the scene where he calmly avoided surveillance and escaped into the water, this person should be bold and careful, and extremely conceited, then it is very likely that he will still stay in Changming City and even continue to do his work five years ago.

Of course, there are other possibilities, human nature is changeable, and some people even quit their jobs after watching a movie to take a walk-and-go journey.

Let's all look at the evidence. The three of them sat together and began to judge, more than 30 teachers, the three of them could not investigate one by one, and there was no need for that.

The Huang siblings go to public schools, mainly close to home, and their community is the school district, Pubei District No. 1 Experimental Primary School and Middle School.

Zhuang Qiang's ability is still okay, he ran all morning, found the teachers of the sisters and brothers when they were in these two schools, and also found the photos of these 20 teachers.

The good thing is that none of the top public school teachers at the district and county level have changed jobs except for two female teachers, and these two female teachers have also changed jobs in the past two years, so the scope of the investigation has narrowed.

Zhuang Qiang pointed to the photos of the two physical education teachers,

"I see, there are so many teachers in public schools, let's just investigate two physical education teachers, the eucalyptus happened in November, and it was raining lightly, and the murderer still had the strength to run so far, only physical education teachers have the physical strength." What he said was a bit absolute, as long as other male teachers exercised diligently, it was also possible, Xu Zheng glanced at the photos of these 20 teachers, and knew why Zhuang Qiang said that he only needed to investigate two physical education teachers.

Of the 20 teachers, 15 female teachers are female, except for 2 physical education teachers, and the remaining three male teachers, tall and thin, are not men who can run horses on their arms.

"Brother Qiang, let's check these three male teachers somewhat, don't make any unseemly things." Zhuang Qiang waved his hand,

"The school has opened, I have met these five male teachers, rest assured, the other three are 100% impossible, standard weak scholars, the kind that is powerless." Since Zhuang Qiang said so surely, Xu Zheng chose to believe him,

"Then at present, the public school will check these two physical education teachers, and the training institution will check 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 man, but there is no substantial evidence that the murderer must be a man, so I suggest that all the tutors who have taught the Huang family sisters and brothers offline should check it." Xu Zheng scratched his head a little, according to what she said, the female teacher in the public school was also suspicious,

"That's it, Sister Mitsuki, let's screen the male teacher first, and if there is no result, let's investigate the female teacher." Ji Meiyue understands what Xu Zheng means, and she has to check the eucalyptus in the direction of key suspicions.

"In fact, it is basically impossible for female teachers in public schools, especially teachers of language, mathematics and English, and then the head teacher, they are already busy enough at school, and the eucalyptus time is around 12 o'clock in the evening, plus it took so long to escape, and the next day has to go to work normally, if the murderer can really do it, it is really difficult." Zhuang Qiang also opened the eucalyptus scroll,

"The investigators at that time actually checked the teachers at the school, and they thought that the murderer was in that situation at that time, and it was very likely that he would catch a cold and get sick, so they focused on the fever clinic and small clinic at that time, and then compared it with everyone related to the Huang family, but unfortunately, no suspicious places were found." Xu Zheng sorted out the teacher records to be investigated, and there were about ten, which could be completed in two days.

"Let's do it together this time, and the focus is to see if they're lying when we take notes on them. And the most important point, secrecy, I always feel that the murderer should not leave Changming City, he should be a very conceited person, and even, he has the urge to do it again. I just hope that the evil in this person's heart is not fully released. Zhuang Qiang and Ji Meiyue nodded, some criminals often have an infinite sense of refreshment after killing, and even for this feeling, they will continue to act as eucalyptus, and many serial murderers are like this.

The Huang family's eucalyptus is the only one in Changming City in five years, which can be regarded as lucky, which is also Xu Zheng's definition of the murderer as a teacher, and he always feels that these teachers will have more humanity than evil.

After sorting out the documents, the three of them were ready to set off, and at this time, the other three people from the second team also came back.

"Xu Zheng, you've been here for two days, do you have any clues about the Huang family's eucalyptus?" With the tone of his jokes, it looks a bit like a joke, their team is responsible for the serial woman death eucalyptus a year ago, in fact, it was a year ago, but the police don't know if the murderer has done eucalyptus before, and there is also a eucalyptus in Changming City in July this year that was incorporated into this old eucalyptus.

But this eucalyptus is said that their team has found a clue, and Zhang Yuqi's current energy is mainly to cooperate with their team to investigate the murder of this woman.

Zhuang Qiang is not usually not competing with Xiao Young, he feels embarrassed, Ji Meiyue rolled her eyes, but she will not say anything to Peng Yue, young people are competitive and do not affect their work, she thinks it is nothing.

Xu Zheng smiled, he didn't want to deal with him, but he felt that he was really ugly when he laughed, and ugliness affected his mood.

"Peng Yue, take a gamble, whoever wants to break the eucalyptus wins, and the loser, Metropark Hotel walks, do you dare?" A meal at Metropark Hotel, a minimum of 3,000 yuan, this is still a case of not drinking, Peng Yue obviously does not have Xu Zheng's financial resources, but their group is definitely ahead at present.

"That's okay, everyone give a testimony, and when the time comes, everyone will order food hard, and it will be according to the monthly salary standard!" Of course, the other team members started to coax, anyway, no matter who wins or loses, they can get a meal, and they don't eat for nothing.

It's just that Peng Yue watched Xu Zheng walk out so confidently, especially Zhuang Qiang, who also took out a file bag and shook it in front of his eyes, obviously this means that their group also has clues.

Peng Yue touched the mobile phone in his trouser pocket and smashed his mouth, in fact, his family is not short of money, but he is definitely unwilling to ask his family for money when he goes to work, but for young people like them, they are all moonlight clans, so he is entangled again, hoping that Xu Zheng and them will lose, and hoping that they can break the eucalyptus of the Huang family.

"No matter, Brother Lang, shall we go out to investigate clues in the afternoon?" The eldest brother Lang in his mouth, his full name is Lang Shaobai, 34 years old, transferred from the Gulou District Criminal Police Brigade, he was still the deputy captain before, two cents and two, deputy section level, he stayed in the second brigade for a year or two, gained some credit, and then transferred to other brigades This is the captain level.

On the line of criminal investigation, the route to promotion must be relatively narrow, and those who can be promoted to this level have unique skills in their hands, and this time the clue to the eucalyptus in their group was discovered by him.

He was also transferred after the New Year, Xu Zheng had seen him a few times before, and he was just familiar. Looking at Xu Zheng's side again, they are also discussing this Lang Shaobai, compared with him, Zhuang Qiang is two years younger than him, and his level is two cents and one, which is one penny less than Kan, so I don't know how much credit is missing.

"Xiao Zheng, if our Captain Zhang is promoted and transferred, the candidate for the captain of the second team will compete with me and Lang Shaobai, so you have to work harder!" Xu Zheng drove the car and was directly amused by him,

"Brother Qiang, just like you, you say to yourself, this captain is for you, do you want to do it?" Zhuang Qiang began to get tangled up by himself,

"Shall I do it or not?" Ji Meiyue's eyelids jumped, how strange are these two people talking,

"With your shocked 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 later, I don't think you all will earn it, and when the time comes, this position will definitely be Xu Zheng." Xu Zheng shook his head in disbelief, the lowest level of the captain of the second brigade of Chongyu must be the main department, although the fourth-level sergeant can enter the main department after two years, but he is still the third-level superintendent.

Seeing that Xu Zheng didn't believe it, Ji Meiyue smiled and patted Xu Zheng's driver's seat,

"If you follow the current rate of meritorious service, I believe there is no problem. Also, I dare say that if you are promoted to the rank of police officer as a technical police officer, then it will be easier to be promoted to a full-time department after two or three years with your status as an undergraduate. "In the police force, technical police officers are indeed promoted faster than investigators, especially those projects with difficult technical barriers, such as the simulation portrait technology mastered by Xu Zheng, but this simulation portrait technology cannot be used as evidence in court trials, and can only be used as an auxiliary technology for police investigations, otherwise, its status in the police will be higher, and it will even become a hot profession.

Xu Zheng didn't dwell on this, anyway, take your time, the police rank can be promoted sooner or later, and the police force ultimately depends on merit and connections.

"Let's not talk about this, the front is the No. 1 Experimental Middle School in Pubei District, should we enter the school, or call the two physical education teachers out?"
