when question marks become people

The boy's name is Jiang Zhen, from another university in the same city, and he came to C University to pick up his girlfriend and go to the station with him.After seeing his student ID card, Lin Yichu didn't intend to dig deeper into him. This small look of shrinking his neck when he saw the police but without strong guard or fear, probably committed a minor crime, and he didn't care about serious things. That psychological quality does.

Thinking this way in my heart, the necessary procedures cannot be missed.Lin Yichu took a photo of a short arrow from his subordinate and put it in front of Jiang Zhen, and asked him if he had seen anything similar, but Jiang Zhen's face turned pale all of a sudden.

It is not Jiang Zhen who is suspected, but nine C college students including Jiang Zhen's girlfriend Han Yue.

These nine students are distributed in different grades and departments. Because of their common interest in cold weapons, they got together and formed a small club in private, called Refrigeration Club.The name sounds like it sells air conditioners, but it actually means making cold weapons.

They rented a house outside the school as a base to make cold weapons by hand.They can't make spears, long swords, daggers and the like that need to be forged. They mainly make bows and crossbows.

I have to say that this group of students are a little bit secondary school hobbies, and their hands-on skills are really good.When Lin Yichu led people into the house rented by the "Refrigeration Society", he saw not only more than a dozen finished and semi-finished bows and crossbows, but also various raw materials and tools.They do their own carpentry, and they also buy materials for more complex crossbows with hacksaws and electric drills. Only a few parts such as eccentric pulleys are purchased online or processed by others.

According to the account of the members, at first they just made according to the finished products they bought and online tutorials, and then began to design their own designs, making them in various sizes.To make something is to test the effect. They used their holidays to shoot birds three times on the nearby mountains, among which there are national second-class protected animals.Afraid that outsiders will be troublesome, they have always done a good job of keeping secrets, and they will not post photos to show off.

After news of the attack on the professor reached the ears of Han Yue and the others, the nine of them went to the rental house where they hadn't been there for two weeks because of the end of the semester. After checking, the smallest crossbow and matching arrows disappeared.

All nine of them had keys to the house, and all said they hadn't done anything like that, and they didn't know what was going on.They are friends, they trust each other to a certain extent, but they don't know the truth, and because they are afraid of the consequences after calling the police, they immediately agreed not to speak to anyone.

Several people were in shock, and the activities that were scheduled to take place after the exam were also cancelled, so they changed their air tickets and tickets, and rushed home.

Jiang Zhen was drawn into the Refrigeration Club by Han Yue. He usually does odd jobs and collects money. He also participated in the bird shooting activity.Knowing that he was timid, Han Yue didn't tell him the truth, but he was still dragged out.Who asked her to force Jiang Zhen to fight the protection of animals, so that he would feel guilty when he saw the police?

Except for the two students who had already returned home, the rest of the club members were taken into the police station on the same day. After comparison, the fingerprints were confirmed to belong to one of the boys named Li Weiqi.

After investigation, including the two people who went home, seven of the ten people had clear evidence of alibi.The other three did not leave after the exam, stayed at school and other club activities, and claimed to be sleeping in the dormitory or hand-painting the design of the bow and crossbow at the time of the incident.

The inexplicable loss of things and the fact that they don't know the truth are just the one-sided words of these students. They can neither prove that they have nothing to do with this matter, but in fact, they are not sure in their hearts that every companion is innocent.Lin Yichu couldn't get more information from them for the time being, so he showed the pictures of ten people to the old professors for identification. It could not be ruled out that one or two of the three people who didn't have an alibi, for their own sake, or for their companions, would be very helpful to the old professors. The professor starts.

I went to Professor Lei's place first, and Mr. Lei said he didn't know any of them. At this time, Mr. He didn't have any impression of any of the students in the photo, or felt that they were very similar to the suspect.Lin Yichu was a little disappointed, and turned his gaze to Wen Hao.

"Excuse me, are you Jin Bei's Wen teacher?"

"I am, Captain Lin knows me?" Wen Hao was surprised, he had never met this police officer before.

"I am Feng Xudong's mother. I often hear him mentioning you. Thank you Teacher Wen for taking care of our Dongdong." Lin Yichu smiled.

It turns out that this is the hero mother in Dongdong's mind.Later, Wen Hao also met the child's father, a policeman in the technical department, chubby, very similar to Dongdong.

The two exchanged pleasantries, and Lin Yichu said, "I won't bother Mr. He anymore, Mr. Wen, shall we go out and say something?"

Wen Hao followed her out, thinking she would say something about Dongdong, but Lin Yichu made a request that surprised him even more.

"I heard that Teacher Wen is proficient in micro-expressions, can you go to the police station and help us find out who is lying among those students?"

Lin Yichu knew about Wen Hao through Dongdong and Xiaoer'er's grandma, but he was deeply impressed after the kindergarten hacking incident.

She has heard about the process of the incident and the subsequent results, and feels that several of them are very suspicious.Why did the criminal froze after the Wen teacher yelled, and then hacked at the air?Why did the criminal act with some logic before, but after being arrested, he was completely stupid and could only spend the rest of his life in a mental hospital?Even if the criminal's mental state is inherently problematic, will it deteriorate so severely when stimulated by shouting?

Lin Yichu consulted someone specifically, and the answer given by the other party was that it was possible, but the possibility was very small.Is it a coincidence, and it's not that Wen Hao has special hypnotic abilities that exceed the normal level?

Lin Yichu wanted to know what was going on, but that was not her jurisdiction. The colleagues and leaders didn't think it was strange, or she just didn't want to cause trouble, it was not for her to intervene.Moreover, Wen Hao is a savior, and her own son has benefited the most, and she has heard a lot of good things about him, at least for now, he doesn't look like a malicious person.I have been a policeman for many years, and I have met several people with special skills. In the words of the child's father, as long as there is no crime, it is not illegal for others to not speak out.

People who deal with criminals instinctively pay attention to special people, even if they are only possible special people.After that, Lin Yichu was constantly busy with things, and he didn't have time to visit the kindergarten, but he would casually ask about Dongdong and his grandparents, Mrs. Wen, at intervals.Of course, what you hear is good and old.

When Lin Yichu saw this young man in He Lao's ward today, Lin Yichu suspected that he was Wen Hao. He was in his twenties, had long hair, and was super good-looking. There were not many people who could fit all of them.

There was no chance before, the other party has come here, Lin Yichu wanted to take a good look at it.Another reason is that she really wants to be supported.

"At first, the school handled it in a low-key manner, and the media didn't report it much. The students of this school also felt that it would damage the school's reputation, so they didn't publicize it. After we brought the students from the Refrigeration Club back to the police station, soon there were rumors on the Internet, saying that the police abused the students. It was done by the parents of the students. Although we can still detain them in the name of possessing controlled devices and poaching protected animals, we still hope to locate the suspect as soon as possible." Lin Yichu explained to Wen Hao.

She and her team members have been working overtime to investigate the case, and the progress of the investigation has been considered fast. After the rumors started, the superiors cast a death curse on them again.Urging is urging, but manpower can't replenish them.Towards the end of the year, criminals are also active.As for the psychologists with the same eyeballs, they couldn't get their turn in the queue.

Wen Hao didn't expect that the micro-expression excuses he made at first would reach the ears of his parents. He doesn't really have experience in micro-expressions, but other abilities may help.It is incumbent to assist the police in punishing criminals early, but he has to confirm one thing first.

"Thank you for your trust. I'm not very good at micro-expressions. I can try it, but I can't guarantee the accuracy. I guess it can only be used as a marginal reference." He was afraid that the police would be too eager to solve the case, amplify his opinions, and bring harm to innocent students.

"Don't worry," Lin Yichu smiled, and she further confirmed that this is a cautious and soft-hearted good person, "I know that micro-expressions cannot be used as evidence, and I will not treat those students roughly according to your speculation. I just hope to shorten the process of solving the case as much as possible."

The role of micro-expressions in judging lies is very limited, and the accuracy rate is very low, unless the other party is a very familiar person.In the process of handling a case, the police must use micro-expressions based on the preliminary analysis of the suspect.Even so, it can only be a support that cannot play a key role. *

But well-trained people can use this assistance, combined with interrogation skills, to judge in a shorter time whether to conduct an in-depth investigation on a certain person first, and whether a certain matter needs to be dug deeper, thereby improving the efficiency of case handling.For example, if you think that A has lied about a small matter through micro-expression, then A is likely to have lied about a more important matter, and this person needs to focus on it.

It is said that teachers are the fastest learners of micro-expressions. Before they know the theoretical knowledge, they can tell whether a student said they forgot to bring their homework or did not do it at all.In turn, this proves that such teachers care about their students from the bottom of their hearts.This is why Lin Yichu was not very surprised when he heard that Wen Hao was good at micro-expressions, and he didn't think it was as incomprehensible as another thing.

Wen Hao is a teacher who understands micro-expressions, and the interrogators are students. Maybe he can really help.

Since he promised to go, sooner rather than later, Lin Yichu went downstairs first, Wen Hao called Ying Annian out and told him about it.

"You know how to interpret micro-expressions?" Ying Annian knew this now. He didn't join the parent group, and he didn't know how to communicate with other kindergarten teachers. Only now was he told this fact that made his heart ache.

"He is so capable", "No wonder he understands children's needs so well", these are all thoughts that came to Ying Annian at that moment.In addition, the man is a little scary - isn't he able to guess what he is thinking? !

Wen Hao didn't know his real question, but he heard a kind of excessive surprise from his tone. This was the first time he saw Ying Annian's behavior outside of Lele's matter.

"Just understand the theory, the reliability is very low in use." Wen Hao explained.

Ying Annian let go of his heart a little bit. A child's mind is simple, but an adult's micro-expression should be much more complicated.This is also someone who has misunderstood microexpressions.

"The accuracy of judgment is higher only for familiar people." Wen Hao continued to explain.

Ying Annian's heart flew up again, didn't he belong to someone he knew well?

The police station is not a dragon's pond and a tiger's den, so Ying Annian decided to accompany Wen Hao there, even if he could only wait outside.On the way to the car, Ying Annian was busy with his mobile phone again, Wen Hao sighed in his heart, this human friend is so nice, he rushed to the hospital to see the professors after working so tired, and now insisted on accompanying him to the police station.

In fact, the man stared at the opened email on his phone, trying to recall in his mind whether he had shown a more obvious expression in front of the long-haired young man, an expression with other emotions.

The conclusion is that not only are there, but many.It seems that many times, after seeing him or talking to him, I found that the corners of my mouth were curled up.

I can't continue like this, I have to put on a straight face again.

When I was young, how did I learn to keep a straight face?

*The micro-expression part refers to Zhang Yue’s answer to the question “In actual cases, how effective is the use of micro-expressions in solving crimes” on Zhihu.When actually writing, I still amplified the role of micro-expressions a little.
