According to the law, the investigation will not begin until 24 hours after an adult's disappearance, and unless there is strong evidence that he or she may be in danger, the police usually cannot provide much police force, and their job is to enter information into the network, and if the person's ID card and other documents appear in the network, they will notify the police.

The law also stipulates that the disappearance of minors can be reported immediately. As for the intensity of the search...... City A is phased, and if it is under the age of 14, the alarm will be activated. If a child between the ages of 14 and 16 goes missing, the Missing Persons Task Force of the Criminal Police Unit will intervene and give priority to investigation. If a child aged 16-18 is missing, the police at the police station will generally visit and investigate first. Nowadays, children running away from home is no longer news, but a fairly common social phenomenon. Especially for children aged 14-18, their experience is very low, almost none. Some people are hostile and defensive towards credible parents and teachers, but they believe untrustworthy people, such as bartenders in bars, ruffians, netizens, etc. This stage is also called the second stage by netizens.

Parents are also very helpless in education, to cultivate children's independent thinking ability, children will be too realistic, he needs to accept a lot of factual information, which is not conducive to children's growth.

However, the situation of the girls' high school is more special, this high school is a closed high school, and you can only go home once every two weeks on the weekend. The entrance and exit of the campus are relatively strict, and students need to be approved by the class teacher before the doorman will let them go. The tuition fee is not low, about 10,000 yuan per semester.

The first year of high school disappeared, and the school and the security department conducted an investigation, but it was not found that the first year of high school had left the school. When the sophomore disappeared in high school, the police retrieved the road section surveillance, dispatched police dogs to search the school, and assigned a search notice to each police station in the city, but found nothing. During this period, two officers of the Criminal Police Missing Persons Task Force had been stationed in the high school, and under such circumstances, three days later, the senior disappeared.

When the police questioned the three friends of the missing person, they all said that they did not find any signs. For example, in the first year of high school, they were in a good mood, and a classmate who slept with them talked and laughed, and their parents contacted them well, and they went out for a barbecue trip together on the weekend, so they were very excited that night.

The first class on the second day was a self-study and early reading class, and there was no show up in the first year of high school, and there was no exercise between classes. The head teacher inquired and went to the dormitory to look for it, only to find that the first year of high school was missing. The last person to see the first year of high school was his friend, and at about half past five in the morning, high school got up and went for a morning run.

The meeting begins.

Fang Ling sorted out the information and said: "After five o'clock in the evening of the second year of high school, it was not until the second class the next morning that the physics teacher found that he had not attended class, and he found out that he was missing after a check. ”

Fang Ling continued: "The time of disappearance in the third year of high school is after 11:20, lunch time, after class, the classmates said that they came to the relatives and wanted to go back to the dormitory first, the classmates didn't care, the first class in the afternoon found that he was not in class, the teacher immediately notified the police stationed in the school, and after a search, it was confirmed that he was missing. ”

Song Kai said: "These three girls have different surnames, the Gao family is average, very introverted, a scholar, her essays have appeared in regular newspapers and books many times, and she is a potential top student that the teacher attaches great importance to." In the second year of high school, his family background is okay, he loves to be in the limelight many times, he has been demerit once, and his grades are in the middle. The grades in the third year of high school are okay, rich, very generous, and have a certain appeal among students. ”

Song Kai: "In terms of appearance, the third year of high school is very beautiful, the second year of high school is very unrestrained, and the first year of high school is ...... More cute?" For a more average-looking woman, Song Kai can't find a more suitable word, anyway, the photo is on the big screen, let's see it for yourself.

Su Cheng asked, "What about hobbies?" He didn't read much of the information, anyway, someone read it. Su Cheng believes they can find the point.

"I don't know...... The only thing they have in common is that they are both science classes. "Liberal arts are not as good as science to a certain extent, and in the words of one teacher, liberal arts have relatively high score requirements, and the choice of career is relatively small, so it is easy to learn. The requirements for science scores are relatively low, and the choice of careers is relatively wide, so it is more difficult to learn. He always advises students that those who have good grades in physical and chemical biology do not study literature, and those who do not do well study literature.

It's already nine o'clock in the evening.

Bai Xue knocked on the door, entered the office, closed the door, and put the documents and letter of appointment on the table: "The documents of the Education Bureau are ready, I am a transfer student in the third year of high school, Fang Ling, you are an English teacher." ”

"Oh...... Blood Extract. Fang Ling asked, "I can't speak English." ”

Su Cheng said: "You can speak English." ”

Fang Ling smiled bitterly: "High school English is not the same as normal English, there are foreign teachers who speak English as their mother tongue to do the college entrance examination English paper, and they only get seventy points. ”

Su Cheng said: "Normal, I minored in Chinese in college, and I never passed. What kind of definite sentence, I really don't know if some people came up with it in order to show Kong Yiji's ability. "According to the survey, many parents of the second generation of immigrants will let their children learn Chinese, but many children are very afraid and resistant after school, especially the introductory pinyin makes the children crazy. Su Cheng personally believes that it is the textbooks that make it more difficult to learn Chinese, such as subject, predicate, object, definite, adverbial, complement, etc., which should be learned by those who need to study and further study, rather than appearing in the compulsory examination in primary school. Of course, this is Su Cheng's personal opinion.

Bai Xue said: "The captain is a cadre of the security department, and the consultant is a hired Chinese English teacher. ”

"Nani?" Su Cheng was stunned: "Why? I don't like English either." ”

Bai Xue said: "Consultant, you have a passport, you are indeed a foreigner, and you have a strong British accent. ”

Su Cheng said: "Actually, I can teach Spanish, Portuguese, and Latin. ”

"Huh?"

Su Cheng said: "Which one to teach depends entirely on whether anyone in this school understands this language. ”

Zoro said: "That's it, let's continue the meeting...... After reading the information, I thought that some of the students must know the clues......"

Su Cheng: "I object, my target is a teacher." ”

"Reason. ”

"I don't think high school students can come up with a model for the disappearance. Of course, it cannot be denied that the three girls disappeared in the same pattern, and they stumbled upon a way to leave the school without being discovered. But I'm more inclined to teachers to have something to do with it, and in girls' schools with plenty of estrogen, male teachers are the stars, so my focus is on male teachers who can be liked by girls. ”

"Is that an entry point?"

"No, it's the direction of my investigation, I have no reason, and I'm not sure of it. ”

Zuo Luo nodded: "I am responsible for understanding the situation of the security department, the access control situation and the student management situation, and Fang Ling and Bai Xue are responsible for the student situation." ”

Song Kai said: "Boss, I desperately want to join the front-line work. ”

Zuo Luo said: "You squat at home." ”

"......" Song Kai was helpless.

Zoro asked, "How's the school surveillance?"

"There is basically no monitoring in the school, only in a safe location, after all, it is not Hengshui. "Hengshui is a well-known high school in the country, and the clarity of classroom monitoring can be seen in the words on the books. The whole school is full of surveillance, so you can't do anything other than studying.

City A believes that the psychological pressure on students is too great, and most students are disgusted with monitoring. It's just that some schools and parents like to control their children's words and deeds, and every move, and the students who are the parties have no right to speak.

City A protects the privacy of minors and also considers their growth psychology. Except for security needs, such as swimming pools, gates, etc., there is no monitoring in other places. Dormitories are even less likely to have. Closed schools don't require much surveillance, either.

Fang Ling asked, "Is it possible for outsiders to invade the school?"

"That's for sure, after all, a school is not a prison. Zuo Luo said: "You also have to take this aspect into account, Song Kai, you are responsible for investigating the situation of students shopping online, going out, surfing the Internet, etc., and it is possible to slip away to meet netizens." ”

"It's not very likely. Su Cheng said: "It is possible to go missing a person, and after the police are stationed, there is still a missing person, I don't think they have the courage to do so." ”

Zoro asked: "The three people are missing, is the mobile phone also missing?"

"Yes. Song Kai replied.

Zuo Luo said: "It's strange, why do you bring your mobile phone when you go for a morning run in high school?" People who are used to morning jogging generally don't like to bring extra cumbersome items. Mobile phones are not a necessity for students, especially at 6 a.m.

Song Kai said: "I will contact the service providers of the commonly used APP software for students to obtain information. However, it is best to find the phone, which may have photos, videos, etc. ”

Zoro nodded: "Okay, let me say one last thing, don't let us settle in, the fourth female student will go missing...... After all, the ability to choose a name for shrimp is limited, and people will laugh at it if you come out of high school. ”

The first possibility is that the student was deceived by outsiders or left the school for other reasons, and in this case, someone will inevitably know something. After all, they are girls, after all, they are still young, and they will more or less mention this to their friends, classmates or teachers. Insiders think they are safe and will keep it a secret for them, and if this is possible, they must dig them up.

The second possibility is that the disappearance of the student is related to the people in the school, which requires an undercover agent to go to the school. As a criminal, you suddenly find that the school has added a few new faces, and you will guess that they are police officers. As an innocent, they may be suspicious, but they don't care. Going undercover is not worried about revealing your identity in front of criminals. With Su Cheng, Fang Ling is an old fritter in front of the students, and it is relatively easy to talk and put some words on his face.

……

Four undercover agents, Bai Xue is not very old, but she is still older than high school students, she spent a few hours, and asked the bureau to help her get her hair and barely get through, so Bai Xue's bottom line is to repeat her studies for three years and aspire to be a transfer student who is determined to be admitted to A University.

Fang Ling is still quite good as a teacher, even if she teaches English in a girls' school, if she teaches English in a boys' school, she is guaranteed to increase the English score of the whole class by 20 percentage points. Fang Ling had undercover experience in dangerous missions in the Anti-Narcotics Department, so Zuo Luo was not worried about the details at all.

As the nephew of the principal, Zuo Luo applied for the security guard to enter the security department, and he does not explain the identity of his relatives of the principal at present. He has undercover experience and is perfectly fine as a security guard.

Su Cheng is still the same as usual, wearing a suit and going to work, undercover experience?

The four of them entered the school separately, and Su Cheng went to the doorman and found that a camera had been installed, apparently a camera with higher definition temporarily installed by the police. Su Cheng showed his certificate, which was the letter of appointment and teacher card issued by the Education Bureau last night. Su Cheng successfully arrived at the principal's office and politely greeted each other, the principal's office did not have anything that Su Cheng wanted to know, and everything the principal knew must have been fed back to the criminal police team.

The principal called and asked someone from the Academic Affairs Office to take Su Cheng to familiarize himself with the environment.

The person who came is called Wang Hai, a physics teacher, who is responsible for teaching physics in the three classes of ABC in the second year of high school, and also helps to handle teaching affairs. Not very old, about thirty, not very handsome, but very strong, very hearty, with a beautiful mouth of teeth people usually like to smile, people feel amiable. Especially for people who have just arrived in an unfamiliar environment.

"Exempt from Gui Su, Su Shi's Su. ”

Wang Hai was quite surprised: "Mr. Su's accent is very local. ”

"Mr. Wang's accent is very capital. ”

"Haha, I studied at the Normal University in City A. ”

Su Cheng introduced himself: "I lived in City A for more than ten years, and then went to London, and I returned to China in April this year. ”

Wang Hai said in a low voice: "You are a policeman, right?"

Su Cheng was stunned: "Police, why police?"

"Huh?" Wang Hai said, "Teacher Su, I heard that English with a British accent is very good. ”

Su Cheng will come as soon as he says so...... The accent, no problem, I can't change it if I want to, so I introduced myself to Wang Hai in English: "I graduated from XX University, and after graduation, I worked in art trading, and found a girlfriend who is from City A, and she hoped that I could go back to City A, so I came back first to see the art market and local laws and regulations." ”

Wang Hai listened very carefully, as if he understood or not: "It is indeed a thick accent, and I can only understand some...... Does Mr. Su drive?"

"I just took the driver's license test in June, and I am very unproficient. ”

Wang Hai pointed to the left and right sides of the main square in front of the main teaching building of the girls' school: "There is a parking lot for faculty and staff, and all the dormitories of our school are outside the school, and many faculty and staff live in their own homes or rent houses by themselves. ”

"All off-campus?"

"If you need to work overtime, there are four rest rooms on the Security Section. Wang Hai pointed to the distance: "There is a basketball court over there, but girls don't like to play basketball, and by the way, they protect the lawn of the football field." The swimming pool is the student union hall over there, the library is on the first floor, the student union office is on the second floor, and there are some club offices. There is also a club office on the fifth floor of the main teaching building. The two dormitories are girls' dormitories, Building AB, one room for four people, and 201 is a dormitory, and they are the only staff members who can stay in the school overnight. Wang Hai and Su Cheng walked forward in the academic affairs building, stopped, and pointed to two large gray one-story buildings: "On the left is the auditorium, and on the right is the canteen." ”

Finally, turning around and looking at the three buildings in front of him, Wang Hai introduced: "The central one is the teaching building, the first one is on the second floor, the second and third floors are high, and the third and fourth floors are high, with a total of three stairs. The building on the left is the Flying Building, which houses a performance venue, a professional library, and a school doctor. The building on the right is the Science Building, which is the Physics and Chemical Experiment Building, and the top six floors are the English Floor, which has a small library, all of which are English newspapers and magazines. Only English is allowed on the sixth floor. It is also called by some students as the outer layer of admiration. ”

"Our school is among the top five in the city in physics and chemistry, but English has always been a weakness. Wang Hai introduced as he walked.

Su Cheng asked, "It's almost the New Year, when will it be a holiday?"

"On the twenty-fifth day of the lunar calendar, there are still ten days to go. ”
