Before Hugo called back, the case was introduced by the leader of Project 1 Team 1, Wang Jiewang (Inspector B of New Territories North CID).

After Jiayi started asking questions, it was Fang Zhenyue who raised doubts again.

When Wang Jiewang said that the New Territories North CID profiled the murderer as a poor and extremely vicious outsider who came here to escape or was a fugitive from a criminal from the outside world, and tried to communicate with the mainland police to look for clues, Fang Zhenyue raised his head and said in a deep voice:

"Sir Wang, if this person is determined to be an outsider, why hasn't a person who doesn't speak Cantonese been found?

" "Can it be determined that he is from Guangdong?

"Or are there any other clues that can give the answer, how exactly did he hide himself in the crowd?

"From one place to another, he can walk completely and walk in the wilderness without being discovered.

"But since he got the money, he will definitely go to buy things. How about going to a place like Sham Shui Po where the population is so dense that people are rubbing shoulders with each other?" "

How could an outsider with strange words and deeds hide himself so well in such a period when everyone is in danger?"

Fang Zhenyue put down the pen in his hand, turned his head and looked at Sir Huang and several other superiors, and continued:

"If it were me, when I saw such a strange person, I would definitely suspect that he was the murderer at the first time and call the police at the same time. "

Everyone knows that Hong Kong citizens' favorite thing to do is to call the police. If the lady next door farts at her doorstep, she will ask the police to come and judge and make the other party apologize to her for 'maliciously destroying the air quality in front of her house'.

If the murderer is a poor and vicious person, how did he convince Hong Kong citizens not to call the police when they saw him?

"..." Wang Jiewang frowned, he couldn't answer this question yet.

Chief Neil Sir turned his head and looked at the criminal psychologist Tannen: "What do you think? Do you think there is a problem with other people's portraits of the murderer?"

Tannen thought for a while, then said: "Based on all the current information, the murderer should be a man with a terrible appearance who is extremely unrecognizable in front of women. He may look very unmanly, such as being short. Or he may be very ugly, or even at his age he still has difficulty in having normal relationships with women. At the same time..."

Tanne turned his head and looked at Jiayi unconsciously while talking.

With her around, he felt less confident when speaking. He needed to see her expression and understand her attitude.

Seeing that Jiayi just lowered her head and stared at the notebook without showing any expression of disapproval, he continued with confidence:

"He should be a kind of 'sexual murderer'. Although appetite is a very important factor, every family he chooses has a suitable young woman. This should be the core factor in his selection of victims' families.

"Every family has money and every family has food. Only these victims have relatively beautiful young women in their families.

"So he did not choose the richest family in the village, but chose the victims who appeared now.

"When our public relations department communicates with the media, we should warn citizens that those who have young women at home should pay special attention to their safety.

"On this basis, when we collect statements and conduct interviews, we should pay attention to whether everyone has seen an ugly, short person who looks suspicious.

"Rather than a poor, vicious, and ferocious person."

Tannen finished speaking, and everyone stared at each other.

The expert who returned from studying abroad threw out a professional term such as "sex murderer" at the beginning, so even if they had objections, they dared not speak casually.

Moreover, it sounded very reasonable.

Neil Sir was just about to take the lead in praising Tannen, or even applauding to encourage him, when he heard Tannen speak again.

Expert Tannen just poked his glasses, and after his speech, not only did he not look proud, but he turned around and asked Yi Jiayi very seriously, eager for communication and recognition:

"Yi Shazhan, what do you think?"

Jiayi did not expect Tannen to ask her suddenly. She raised her head from the notebook, thought for a while and then said:

"I'm thinking, is it possible that the murderer has a stutter, or pretends to be mute, or is deaf or something like that?"

"Ah?" Tannen was completely stumped by Jiayi's sudden question. This train of thought was too fast and he had not even thought of it.

Jiayi's mind was completely absorbed in her own thoughts, and she almost forgot that they were in a conference room. She simply pushed her notebook in front of Tannen, pointed to the mind map she had drawn on it and said:

"I have been wondering about the question that Brother Yue just raised. I was still thinking about it on my way to work this morning on my bike.

"Based on the murderer's route of committing crimes and the fact that he couldn't even eat, he does look like an outsider.

"Then he is a stranger and he may not speak the language. Even if he can speak Cantonese, we can tell by listening to his tone and looking at his expression.

"Then how did he fool everyone?

"T sir, think about it, if I am a short, poor man who seems to have no killing power, stutters, has a bitter face, and seems to have some intellectual disabilities, would you be jealous of me, think I am a murderer, and call the police to investigate and arrest me?"

"If I am a good person, I might give you some food. If I have a bad temper or am not very kind, I might chase you away and scold you." Tannen thought about it seriously and said.

"Yes, so I agree with your profile. The murderer may not seem to be easy to arouse people's defense. On the other hand, he may also look a little pitiful." Jiayi said, lowered her eyebrows and smiled, "Of course, it's just a guess at this stage. I need to know more information before I can talk to you in more depth."

"I understand." Tannen nodded quickly.

Sir Neil had long forgotten about praising Tannen. Instead, he patted the Chief Superintendent of the West Kowloon Serious Crime Unit, Sir Wong, on his left. It was obvious that he recognized Sir Wong's training and attention to young police officers. This was to praise Yi Jiayi.

"Then, colleagues in the New Territories North Serious Crime Unit, when you are doing interviews and collecting statements, please find some poor men who stutter or pretend to be deaf-mute." Fang Zhenyue immediately spoke up and asked others to put Yi Jiayi's speculation into practice.

"No problem." Wang Jiewang immediately stretched out his hand and made an "ok" gesture.

Ou Zhuhao turned his head to look at Superintendent Wong, and felt that the West Kowloon was indeed very good, so he was very dissatisfied with the Inspector Sergeants of his own New Territories North Serious Crime Unit.

He turned around and gave the police officers sitting in his row a cold look, and everyone immediately felt the pressure.

So in the following communication meeting, the police officers from the New Territories North tried their best to express themselves actively, asking questions, and proposing ideas, making the meeting very lively.

The West Kowloon police were not to be outdone, and they also spoke enthusiastically and expressed their opinions.

Superintendent Wong and Au Chu-ho even sat up straight, their eyes were electric, and they exchanged a lot of words.

Neil Sir was happy to see this happen. After all, it was a good thing for the case. This was the kind of work attitude he wanted from everyone.

When he thought of the person who inspired everyone to get excited, it seemed to be the female sergeant who was taking notes and thinking while making a little head-touching movement. In an instant, like Superintendent Wong, he liked this serious and active young female police officer more and more.

Seeing Neil Sir showing an admiring expression towards the sofa in West Kowloon, the police officers in the New Territories North could not sit still anymore, and they spoke more and more hesitantly and with increasing frequency.

Jiayi sat in the conference room and looked at another female inspector, and they both smiled bitterly.

They had seen the competitive spirit of men. Although they tried to be low-key and restrained, their desire to show off was not much different from elementary school students raising their hands to answer questions.

After sitting for a while, Jiayi found that she couldn't even listen to Inspector Wang Jiewang's smooth and consistent introduction of the case.

She frowned and looked up, and saw that another inspector from the New Territories North opposite her wanted to express his opinion on Wang Jiewang's introduction - this was not a normal discussion of the case at all, it was simply like a bureaucratic rhetoric meeting.

Jiayi was reaching the limit of her patience. Since you guys are praising me so much, I won't be so low-key.

So, before the other party could "express her opinion", Jiayi spoke first. Do

n't interrupt Sir Wang with one question after another. Let's just discuss all the doubts at once.

So, she followed Wang Jiewang's words and asked more than ten questions in a row. She

read the doubts that she had listed in her notebook last night one by one.

At first, the inspector who had not been able to speak first was a little unwilling. Gradually, when he heard her mention the fourth question, he finally put down his arms, and his expression twitched unnaturally. He was glad that he didn't just talk nonsense.

Since she had already started talking, Jiayi simply asked questions while helping the entire task force sort out their ideas -

from the similarities and differences between the victims to the possible portrait of the murderer's appearance, height, characteristics, etc.;

from the evolution of the murder weapon "sharp kitchen knife" to "blunt hammer", it reflects that the murderer was gradually aroused to "vent desire", gradually evolving from a person who only wanted to satisfy his appetite and sexual desire to also want to vent his "violent desire". It can be seen that the murderer's appetite is getting bigger, and his cognition of "self-improvement" is also expanding;

from the analysis of the murderer's multiple crime locations, it is professionally summarized as "geographical portrait". Based on this, it can be inferred that the crime scene is an "unorganized crime scene" with the characteristics of "spontaneous crime", "the victim is identified as a stranger", "depersonalization of the victim", "messy crime scene", "rarely talking", "the body is left at the first scene", "the victim was sexually assaulted after death", "having considerable anti-detection ability", "staying away from familiar areas and familiar people", etc. He may be afraid that the police will patrol more in the place where he originally committed the crime, and he will be caught. Based on this analysis, is it possible that the murderer's next crime area will be a certain distance from Shek Kip Mei? It is difficult to take a boat from the pier to Hong Kong Island (Central, Causeway Bay, etc.). All ships require him to show his documents. Is it possible for him to continue south to Hung Hom, Yau Ma Tei, Tsim Sha Tsui, etc., or go west to Kwai Chung, or go east to Kowloon Bay or Tseung Kwan O?

Jiayi started from the idea of ​​solving cases in the officialdom in the past, ignoring the huge amount of information and clues, and only extracted the most core ideas for solving cases, and asked Wang Jiewang questions to extract the most core questions.

When Fang Zhenyue heard the third question, he stood up and went to the whiteboard in the conference room. According to the questions she asked, he listed Jiayi's mind map one by one.

Then, according to Wang Jiewang's answer, he marked the core information on the outer circle of the mind map, and did not record the information that he thought was useless for the time being.

The participants were soon attracted by the two unrestrained inspectors and sergeants who dared to take the initiative and the right to speak even with the assistant director present. Their eyes fell on the tip of Fang Zhenyue's pen and then on Jiayi's face who asked the question.

Neil Sir also observed Fang Zhenyue and Yi Jiayi for a while, and couldn't help thinking that it was true that the inspector taught the sergeant. A guy who didn't care about authority, procedures and official atmosphere also taught a child who was "lawless" but focused.

Although the ability seemed very strong, it would be uncomfortable for a superior to have such a subordinate. Being disobeyed and interrupted from time to time... but still not losing his temper, admiring and promoting these young people, this must be a very broad-minded and upright superior.

When Neil Sir looked at Superintendent Wong of the West Kowloon Crime Unit again, his eyes finally showed some pure admiration.

"?" Superintendent Wong.

Why are you looking at me like this again? Today you always praise me, admire me, and identify with me, why do you still show this... distressed and emotional expression?

What does it mean?
