Anseong.

The autopsy and trace examination continued, Yan Quan instructed the technicians to check the surveillance, and then walked to the person who called the police, who was the deceased's girlfriend.

The girl's face was still so pale, and there was already a brightness in her eyes at the moment, not as dull as when she had just discovered the body.

This is a normal reaction, and for ordinary people to die is already terrible, not to mention the bloody scene and the empty eye sockets. And that weird smile.

If you are very timid, you can be scared straight into the hospital.

"Are you alright?" Yan Quan's voice was soft.

The girl timidly nodded slightly.

Yan Quan: "Can you tell me what's going on?" ”

The girl replied, "I ...... I didn't know, we had already opened the room, and he said to buy a ...... health products, but I haven't come back for half an hour, and I didn't answer the phone, so I came out to look for ......"

Yan Quan: "You are students in the School of Nursing?" ”

Girl: "Hmm. ”

Yan Quan: "How old is it?" ”

Girl: "Graduated." ”

Yan Quan: "What's your boyfriend's name?" ”

Girl: "Ma Ziping." ”

Yan Quan: "Locals? ”

Girl: "No, he's from Yangcheng, I'm a local." ”

Yang cheng?

Hearing this city, Yan Quan's first reaction was to think of Chen Yi, the last serial murder case in Jiangcheng, the other party became famous in a fight.

After the two chatted for a while, Yan Quan didn't get any effective clues, Ma Ziping lived a very simple life, stayed in school all day like most students, went out to either party with classmates or fall in love with his girlfriend, and the girl didn't hear that Ma Ziping had an enemy.

The next step was to check the monitoring and visits, which lasted until late.

Ancheng City Bureau.

Yan Quan is waiting for the results of the appraisal in the technical department.

"Team Yan, only this footprint is more suspicious, but it's not quite right." The officer picked up a piece of translucent paper and showed it to Yan Quan.

Yan Quan was surprised: "So small? ”

The police officer nodded: "Thirty-four size, under normal circumstances, it is worn by a child around ten years old, if it is an adult, a woman of about one meter five is most likely." ”

Yan Quan said to himself: "About one meter five, a woman...... What the? ”

"Okay, I see, I'll go to the medical examiner's office."

……

Yangcheng City Bureau.

The criminal investigation detachment was still working overtime, and in three days, under the leadership of Chen Yi, all the field staff carried out a comprehensive visit to the interpersonal relationship of the deceased Yang Xiuming.

Classmates and teachers at school, relatives at home, children of relatives, women who have spent money to find, it can be said that as long as it is someone Yang Xiuming knows, they are all among the visits.

As a result, there is no result, everything is fine.

At this moment, Chen Yi is repeating the investigation and monitoring with Shi Xin in the Communications Department, and they still believe that the murderer should not have left after committing the crime.

At least, it cannot be ruled out that the murderer has left.

Tamper monitoring is a low-probability event, just in case it is checked to make sure there is no problem with the monitoring.

"Where did you miss it?"

It was very boring to watch the surveillance, and when he flicked the cigarette ash, he said, he was referring to the interpersonal relationship of the deceased.

No suspicious points were found, and the incident itself was rather strange, and the death of the deceased was so miserable, it stands to reason that it would not be for no reason.

Chen Yi leaned back in the chair, supported his head with one hand, and said, "There are two possibilities now. ”

"First, we haven't investigated comprehensively enough, we don't know who Yang Xiuming must have offended."

"Second, it was a stranger who killed Yang Xiuming."

When new: "I'm starting to lean toward strangers now." ”

Chen Yi: "Let's talk casually, if it's a stranger, what is the motive?" What are the fatal characteristics of Yang Xiuming? ”

When did Xin think about it and said, "My private life is too chaotic?" ”

Chen Yi nodded: "This is one of the characteristics that we have mastered so far, and the other is that Yang Xiuming was a thorn in the school when he was in middle school." ”

"Whether it's an acquaintance or a stranger, I don't think you can escape these two points, right?"

Shi Xin pondered for a while and asked another question: "What do you say about size 34 shoes?" ”

In the past few days, he saw that Chen Yi's eyes had not taken off the thirty-four yards left at the scene, and he still felt that it came from the murderer.

Thirty-four yards, a bit odd, is out of the realm of a normal case.

Chen Yi: "Four possibilities, which one do you think is bigger?" ”

"First, a child around ten years old."

"Second, an adult female of about 1.5 meters."

"Third, an adult male of about 1.5 meters."

"Fourth, big feet wear small shoes."

When the new does not hesitate: "Of course the second possibility is more likely." ”

It is impossible for children to kill, men of about 1.5 meters occupy a very low proportion of big data, and it is not necessary to wear small shoes with big feet, so it can only be given priority to adult women of about 1.5 meters.

Chen Yi: "I thought so at first, but after a few days of investigation, this possibility has become smaller and smaller for me. ”

When is it new: "What do you think?" ”

Chen Yi was silent for a while, and said, "We can start thinking about low-probability events when we investigate the high-probability events first." ”

"Dwarfs, or short stature due to other diseases, that's the fifth possibility."

Shi Xin thoughtfully: "That's right, although it's usually difficult to come across, but now I can't rule out this possibility, but ...... Although the dwarf is short in stature, its appearance is generally the same as that of an adult, and the visit was fruitless...... Let me see. ”

After speaking, he leaned over and began to operate the computer, adjusting the monitoring time to the moment when the police arrived at the scene of the crime.

The previous visit was very detailed, and there will definitely be questions such as: have you ever encountered strange things, or have you met strange people.

If someone in the neighborhood has seen a guy who is not developing properly, they should have an impression.

"There are a lot of children."

When to keep an eye on the monitor, fast-forward pause, fast-forward pause, repeat the operation, the goal is to find the figure of the suspicious "child".

But this is only road monitoring, not comprehensive, and there are still a lot of onlookers on the other side of the roadway.

He continued to call up the farther surveillance, and the entire neighborhood was seamlessly encircled at 360 degrees.

Chen Yi looked at the new movement and waited quietly.

The case has now reached an impasse and new leads are needed to break it.

If you check it again, you will have to check it in high school, and tomorrow he will take someone to the 15th middle school to interview Yang Xiuming if anything unusual happened in high school.

The scene where it is not too late for a gentleman to take revenge for ten years may also exist.

Judging from the real case, some people who threaten to kill your whole family in a few years will really do it, never underestimate human nature.

When a cow goes crazy, it will go on a rampage, and when a person goes crazy, it will bleed.

In the early hours of the morning, Chen Yi was drowsy and was woken up by When Xin.

"Is there a catch?"

Chen Yi shook his head and looked up at the monitor.

Shi Xin pointed to a figure in the surveillance screen and said, "Look, this child." ”

Chen Yi approached.

In the picture, a ten-year-old child leaves the alley with his head bowed, his pockets bulging, and he doesn't know what to pack.

Because he lowered his head, he couldn't shoot his face from the surveillance.

Time is the moment when the police investigate the scene.

Chen Yi stared at the children in the picture for a while, and said, "This time happens to be the time to go to school, are there any other children walking away?" ”

If not, then it's rather suspicious.

Shi Xin said: "Yes, but only this child walked alone." ”

Chen Yi: "Find the clearest screenshot, and let Zhuo Yun visit this community again tomorrow, so that everyone can recognize whose child or whose relatives it is." ”

When is it new: "What if you don't know each other?" Do we really want to suspect that he is the murderer? ”

Chen Yi didn't answer, and said visually: "He's one meter five tall, right?" ”

When the new eyes were on the surveillance, he hesitated: "Without a reference, I can't see it." ”

Chen Yidao: "Why not, the height of the small common trash can next to it is generally 70 centimeters to 100 centimeters, judging from the curb next to the garbage can, the curb of more than ten centimeters corresponds to about 80 centimeters of garbage cans, and then the height of the corresponding child is about 1.5 meters." ”

Hearing this, Shi Xin was surprised: "I'll go, humanoid computer, you, visually measure your height at a glance." ”

Chen Yi's brows furrowed slightly, and he didn't pay attention to the new compliment: "The height is right, won't it?" Let's check it tomorrow, let Zhuo Yun check, let's go to the fifteenth middle school. ”

When Xin nodded: "Okay." ”

The next day, a new round of visits began, Zhuo Yun took people to the community where the crime scene was located, looking for the family who knew the child in the surveillance, and Chen Yi came to Yangcheng No. 15 Middle School with Shi Xin.

Four years have passed, and the only one who can ask is the teacher, so Chen Yi and the others went directly to the principal's office.

The criminal policeman's arrival frightened the principal, and he hurriedly greeted him politely and asked what was going on.

"Something happened to the former student?"

The principal breathed a sigh of relief, fortunately, it has nothing to do with the fifteenth middle school.

There is no small difference between an accident involving a university student and an accident involving a secondary school student, the latter can be labeled as negligence in management, and the family will have to look for all the points that can increase the compensation.

For example, is there a mental health counseling class in the school? Theoretically, there should be, but most high schools generally don't have it, and family members will hold on to it.

Chen Yi: "Principal Lu, can you call Yang Xiuming's homeroom teacher back then?" ”

The principal nodded: "Of course, wait for me to let people check the information, and then call me immediately." ”

Chen Yi: "Thank you, Principal Lu, for the trouble." ”

The principal smiled: "You are polite, you should be, you can chat and drink some water first, and it will be fine for a while." ”

About twenty minutes later, Yang Xiuming's head teacher came to the principal's office with a blank face, unable to figure out why the police suddenly looked for him.

"Mr. Zhao, these comrades are comrades from the Criminal Investigation Detachment of the Municipal Bureau, and I have some questions for you." After speaking, the principal looked at Chen Yi, "Do I need to avoid it?" ”

Chen Yi: "No, no, let's talk a few words and leave." ”

Headmaster: "Okay, let's talk." ”

With that, he went back to his office chair and sat down, ostensibly working on documents and not caring about the content of the conversation, but in fact he would definitely listen.

After Teacher Zhao sat down, Chen Yi spoke: "Excuse me, do you remember Yang Xiuming, this student?" ”

Mr. Zhao is a middle-aged man with glasses, his hair is a little oily, it is estimated that he has not washed it for several days, and he looks like he teaches either mathematics or physics, and he is not kempt.

Hearing the name Yang Xiuming, his memory was opened, and he immediately nodded: "Remember to remember, how can you forget this." ”

Chen Yi: "It's been four years, I remember it so clearly, is there anything special about him?" ”

Teacher Zhao said: "Yang Xiuming is very difficult to manage, and he quarreled with me, just in the class, when he pushed all the books on the table to the ground and yelled at me, of course I remember this kind of student very clearly." ”

Chen Yi nodded.

There are only two kinds of students that middle school teachers can remember after many years: those who are good at studying, those who are restless and naughty in adolescence, and Yang Xiuming belongs to the latter.

"About Yang Xiuming, can Mr. Zhao tell me more? Preferably something impressive, such as who you quarreled with, who you fell in love with. He continued.

Teacher Zhao recalled for a while and said, "I also learned from other students, Yang Xiuming's reputation in our school seems to be quite big, and other students don't dare to provoke him, and if they dare to provoke, they will be beaten." ”

"This kind of student is a thorn in every middle school, smoking, drinking, falling in love, and doing everything, but if it is too serious, there will be no more, otherwise he will be expelled from school long ago."

Chen Yi: "Has he ever been criticized by the whole school because of something?" ”

Mr. Zhao: "Not really. ”

Chen Yi: "Do you know who his best friend was at that time?" ”

The main thing he wants to ask is this matter, the teacher has limited information, and the one who knows Yang Xiuming best must be his fox friend and dog friend.

Teacher Zhao thought for a while and said, "Yang Xiuming has a good relationship with two students, I often see them together during recess, one of them I don't know, and the other is Ma Ziping in the class. ”

Chen Yi: "What three words?" ”

Teacher Zhao: "The horse of the cow and the horse, the son of the child, the peace of peace." ”

Chen Yi: "How tall is Ma Ziping?" ”

Teacher Zhao: "I don't know about this, it's not short." ”

Chen Yi: "It's more than 1.5 meters, right?" ”

Teacher Zhao was stunned for a moment, a little strange: "Definitely, if you don't say anything, you have to be 1.8 meters, the current children are developing very well, and high school is a period of soaring." ”

Chen Yi nodded slightly and continued to ask, "What was the name of Yang Xiuming's girlfriend at that time?" ”

This made Mr. Zhao frown, in his opinion, high school love is early love and not doing business, and subconsciously feel uncomfortable with the word "girlfriend", at most it is a chase between adolescent kittens and dogs.

"Ren...... Ren Xuan, yes, it's Ren Xuan, I've seen them holding hands, and I've criticized them individually. ”

Chen Yi: "Okay, thank you. ”

After asking Teacher Zhao everything he knew, Chen Yi and the others left the 15th Middle School and returned to the car.

The car did not start, when the new is checking people.

Five minutes later, he looked at the computer screen and said, "Ma Ziping, I graduated from high school and was admitted to Anseong Nursing College, and I should graduate this year." ”

"Anseong?" Chen Yi thought of a person, "Yan Quan's place with Captain Yan." ”

When Xin hummed and asked, "Go to Anseong or make a phone call?" ”

Chen Yi: "There are no direct clues for the time being, let's call, call now, turn on hands-free." ”

When new: "Okay. ”

He took out his mobile phone and dialed Ma Ziping's number, but after a long time, no one answered.

"Fight again." Chen Yidao.

When to continue dialing newly.
