The next day, the news of the establishment of the task force was published.

At the same time, newspapers of all sizes in Hong Kong published a rough portrait of the murderer, asking everyone to call the police and protect themselves if they encounter such a suspicious man.

In terms of how to prevent the murderer from breaking into the house at night, the police also provided more prevention plans based on the murderer's crime patterns.

Just from the strength of this publicity, the citizens have already felt the degree of attention that the Hong Kong police force has paid to this case after the establishment of the task force.

In the morning, when the four brothers and sisters of the Yi family went out, they had to move the extra-large cabinet blocking the door - a heavy object that required four people to push open, and it was definitely an obstacle that the murderer could not push.

The Yi family was already very serious about preventing murderers. Ah Xiang and her friends were even more dangerous because they were two weak women and Sun Xin, who often came home late or stayed overnight on the set. So Jiayi encouraged her eldest brother to buy them an alarm and install it at the door of their room. When it was turned on at night, the alarm would sound immediately if someone entered. At the same time, they put a dagger under their pillow and had to sleep with a baseball bat.

Jiayi even started planning with Clara to raise a large dog...

Not only were the citizens in danger, but even the police's families were very scared.

...

Hong Kong in June has gradually entered summer, and the police station has also resumed the tradition of ultra-low temperature air conditioning during working hours.

The police station was deserted in the early morning. The air conditioner had just been turned on, so it didn't feel cold yet.

But as soon as Jiayi stepped into the police station, she shuddered out of habit. Although she is now hotter than before because of her fitness exercises, she is still far behind those hot-blooded young people.

Therefore, drinking iced coffee wrapped in an air-conditioned blanket has become her latest weird habit.

At 10:30 in the morning, the task force will hold its first task discussion meeting.

When Jiayi walked into the office, she was thinking about how to prepare the information, what to say at the meeting, and how to go to the North New Territories to find a forensic officer to see the bodies of all the victims after the meeting. As a result, as soon as she walked in, she saw Fang Zhenyue sitting in a massage chair, reading the materials in his hand while enjoying a mechanical massage.

"Good morning, Brother Yue~" Jiayi smiled at the morning sun, and her whole person was blooming.

Fang Zhenyue saw her when she entered the room. His eyes followed her all the time. He nodded and whispered "Good morning". He slowly put away the information in his hand and asked:

"If we rush to the New Territories North Serious Crime Unit now, we should be able to catch the task force meeting at 10:30. Do you want to drive directly to the New Territories North Serious Crime Unit, attend the meeting with them face to face, and then go to see the body with their forensic officer, or go through all the crime scenes with their colleagues in the Forensic Department?"

"!" Jiayi's eyes widened, "Brother Yue, you are simply my...confidant!"

Fortunately, she was quick-witted and changed the word "roundworm" to "confidant" before she could spit out the word.

Fang Zhenyue glanced at her, jumped up from the massage chair, turned off the movie, shook the key in his hand, and strode away.

Before Jiayi could even take a sip of warm water, she put on her air-conditioning blanket and squeezed the iced coffee that Fang Zhenyue had bought when he came in the morning. She followed Fang Zhenyue and got on the jeep, heading straight to the New Territories North Crime Unit.

On the way, she was thinking about what she was going to say at the meeting and what she was going to do after the meeting, and she gradually dozed off.

In the next blink of an eye, she was already in the New Territories North. Was it Brother Yue's speed that was getting faster and faster? Or had she slept too long...

Rubbing her eyes, Jiayi regained her working state and strode into the New Territories Crime Unit's site.

There were no familiar faces in the office that would greet each other warmly. There were only curious or scrutinizing eyes, and some whispers: "It seems to be the Sargent who was often in the newspaper last year at the commendation meeting..."

Led by a female police officer, Fang Zhenyue and Jiayi walked into the meeting room of the Serious Crime Unit.

Wang Jiewang turned around and saw the two people. He immediately stood up with a smile and greeted them and asked them to take a seat.

The time was just right, and the meeting began just after I sat down.

In the offices on both the New Territories and Kowloon sides, each introduced which detectives were present. Then Wang Jiewang, as the head of the think tank, pushed the meeting forward directly.

Everyone first shared some of the latest situations from yesterday to now, and took turns to speak in tacit understanding and courtesy.

"Yesterday was the first time the task force integrated the case information and published an advertisement after it was established. Considering that the murderer would avoid the police, we have limited plainclothes officers we can dispatch, and the murderer's activity area is not restricted, so we still decided to publish the latest portrait of the murderer and keep an eye on the murderer through the eyes of the citizens.

"Between [the murderer can recognize and read traditional Chinese characters, saw the information in the newspaper and changed his appearance] and [the citizens are completely unprepared for the murderer', allowing the murderer to move forward with the next case without any psychological burden' and [the police force is insufficient and the murderer cannot be captured in time], we decided to lean towards the latter option and provide the public with a possible portrait of the murderer.

"The newspaper was published this morning. So far, we have received more than 200 calls related to the case. Among them, we have screened out more than 50 calls that may be effective clues. The support team has split up personnel to follow up and verify these more than 50 reports. Some of the verification information will be fed back to me before this afternoon, and I will share it with everyone as soon as possible."

Wang Jiewang held the first document in his hand and announced it to everyone.

"Here, I would like to thank the West Kowloon Serious Crime Unit B Group, that is, Special Project 6 Group Inspector Fang Zhenyue and Yi Jiayi Shazhan for providing ideas." Hugo, who was sitting next to Wang Jiewang, turned his head and glanced at Wang Jiewang. Seeing that he was not prepared to say anything more, he hurriedly smiled and added.

"No problem." Fang Zhenyue nodded unceremoniously.

"It's just a compilation based on what everyone has worked hard to find out. It's nothing to mention." Jiayi smiled and played the humble role.

Wang Jiewang looked up at Jiayi, then at Fang Zhenyue, and immediately came to the conclusion: the EQ of the West Kowloon Serious Crime Unit B was in charge, and it didn't look like Inspector Fang Sir.

"Although many reports are investigated by the support team, one of the calls was particularly core, so I took over and followed up directly.

"It was an hour ago. A middle-aged woman living in Fanling reported that some food was lost from her house a while ago. At that time, because no money was lost, they thought it was stolen by wild cats and dogs nearby, and did not report it.

"It was probably the fourth day after the Sheung Shui murder case, which was between Case 1 and Case 2.

"However, there was a special situation at that time, that is, there was an old kitchen knife in the house. The woman thought it was a broken thing that the elderly in the family found at the flea market, so she threw it aside without using it or caring about it. Today, when I saw the newspaper, I suddenly remembered the kitchen knife lost in the first Sheung Shui case, and remembered that the newspaper mentioned that the murderer killed people for food and money...so I reported the case.

"I personally took Mr. Qian from the Forensic Department to retrieve the kitchen knife, took some photos in his home, and did some on-site inspections."

Before taking out the photos, Wang Jiewang simply drew a diagram of the house layout on the whiteboard.

Although the drawing is very abstract, it can be roughly seen that this gatehouse is built on the edge of the village and occupies a relatively large area. The kitchen and bedroom where food is stored are some distance away.

Wang Jiewang pointed to the kitchen and said, "The blood stains and fingerprints on the kitchen knife have confirmed that it is the kitchen knife used by the murderer to kill a family in Sheung Shui Village. It is also consistent with the knife rack in the home of the Sheung Shui murder case. "

In other words, the murderer stole the food from the Fanling family and left directly.

"The food was probably enough for him to eat for two days. After he ran out of money and food, he committed the Fanling murder."

"It seems that... the murderer committed his first murder in Sheung Shui. The reason for the murder was probably because he happened to meet the little girl of this family while stealing food, so he had evil intentions." A police officer in the New Territories North said. "The

first victim found in Case 1 died at the kitchen door. He was strangled to death by the murderer's bare hands. This behavior was probably accidental." Another inspector who followed up on Case 3, the Tai Po murder, answered.

"Yes, if this was his first murder, then this little girl who accidentally caught him stealing was the first person he killed and raped."

"He was caught by accident and killed in panic. After the murder, he became emotionally agitated, and his hormone levels, such as adrenaline, suddenly changed. Under the stimulation, he became murderous and impulsive, and killed the whole family." Sun Anzu, a forensic officer in the North New Territories, made an inference and analysis based on his expertise.

"I have read the files of these cases, and it is very likely that it is consistent with what Mr. Sun said. Of course, the murderer was originally a person with great emotional fluctuations and was not good at controlling his temper. Being caught stealing by a little girl was the trigger point that stimulated him to kill. Fear, shame, anger, and many other emotions were at work, and he lost control and committed this crime." Tannen, an expert on the other end of the phone, also interjected.

"So, at this time, the murderer had not yet become a serial killer. Before Case 2 happened, when he went to steal food from the family in Fanling, he was probably still in a stage of being tired, panicked, and afraid of being discovered by the police. So he just wanted to steal the food and then continue to flee south to find a solution. But in Hong Kong, you need an ID to do anything, and the situation became more tense after the case happened. He wanted to It was difficult to find a job. Everyone was wary of strangers. After stealing the food, he found that there was still no other way to solve the problem. It had been four or five days since the crime. Hunger overcame the fear after the murder. Seeing the uniformed police coming and going to the north to investigate the Sheung Shui case, and the media also running to Sheung Shui, he had no idea, so he became bolder. "

Jia Yi also raised her head and expressed her opinion:

"These tensions were reduced to the limit under the pressure of hunger. It is very likely that hunger also made him hate and anger this society and others more, and his bloody desire soared, and he simply turned from passive to active.

"He planned to choose the second family, a family with a young woman who could satisfy his two major needs of appetite and sexual desire. "

Yes, so the act of stealing food and dropping the kitchen knife between Case 1 and Case 2 was a transition for him from an impulsive killer to a serial killer." Fang Zhenyue continued.

Wang Jiewang then marked this critical period on the whiteboard.

"But, based on this, what useful insights can we get? "A sergeant turned his head to look at everyone who had just spoken, and then looked at Wang Jiewang.

Then, the conference room fell into silence.

Yes, what is the significance of deducing these things in catching the murderer and solving the case?

Is this information useless?

After nearly ten minutes of contemplation in the meeting, when Wang Jiewang was about to give up discussing this topic and consider moving on to the next step, Jiayi suddenly spoke up and broke the silence:

"There is revelation. "

Everyone looked at Jiayi. Most people only knew that Yi Jiayi had some abilities, but they were still confused about how she was so strong and why she was recognized as an outstanding detective by the bosses of the two major departments at the end of last year.

People tend to either admire and trust things they have never seen too much, or they are dissatisfied and don't take it seriously.

The detectives present were all successful and capable, so naturally they would not have a "perfect admiration" for Yi Jiayi. After the last meeting, they had seen her enthusiasm and cleverness, but how professional and talented she was... they still had to observe her carefully with scrutiny and curiosity.

Jiayi pulled her lip slightly towards everyone who was looking at her, and then said in a loud and clear voice:

"The murderer changed from a reckless and accidental killer to an inevitable serial killer who actively seeks targets, which means that his thinking changed from disorder to order.

"Since it is orderly, then we can feel this 'order', and perhaps we can think about what the murderer is thinking, and then intercept him one step ahead of the murderer."

Before the murderer is caught, all the analysis and portraits of the murderer are meaningful, because the police are in a blind spot and don't know which point may be the most important flash of inspiration, so all clues must be collected.

If you arbitrarily think that some information and analysis are useless, it is very likely that important clues will be missed due to negligence.

This is the poor method that Brother Yue taught her when she was learning how to be a detective like a sponge. Don't be lazy and avoid any thinking, no matter how small.

Only by developing the habit of "not ignoring small clues" can one become a powerful detective who keeps an eye on everything.

"Yeah, that makes sense." Wang Jiewang nodded, glared at the sergeant who "questioned everyone's discussion, did not think carefully, and asked questions directly", and then turned around and asked more humbly:

"Does Yi Shazhan have any ideas?"

Hugo began to scratch his ears and cheeks again.

Yi Shazhan said that this discussion was meaningful, but he did not say that he had any ideas. If Yi Shazhan could not answer the question by calling on him, wouldn't Wang Sir's behavior be like mocking Yi Jiayi for daring to speak out when she had not thought of anything...

Isn't Wang Sir slapping Yi Jiayi in the face in public!

Hey, Sir Wang, don't mention Inspector Yi's name, why don't you just ask everyone if they have any inspiration?

Hugo sighed softly.

Inspector Wang Jiewang will not be satisfied if he offends one person a month. Sir Wang's goal is to offend one person a day, right?

Everyone looked at Sir Wang with strange expressions, and then looked at Yi Jiayi's face secretly.

However, the imagined blushing expression did not appear on Yi Jiayi's face. On the contrary, the female Inspector was calm, as if she didn't realize there was anything wrong with Wang Jiewang's question. Jiayi nodded seriously

: "This is what I think. When the murderer chose the victims in the northern New Territories, he chose those whose door locks were easier to open, who had women, food and money in their homes, and most of them were families in the marginal areas of the villages.

"I saw the judgments made by Sir Wang and other officers who handled the North New Territories serial murder case--"

She took the document and read out the document provided by the North New Territories Serious Crime Unit:

"[The murderer's goals are: to satisfy sexual desire and appetite. Excluded are new-version security doors, families with dogs, families with a large number of young people...]

"Although this conclusion is very accurate, is it possible that it has changed?"

Jia Yiru discussed the case with everyone in the Group B office, chatting and asking questions according to her own thoughts.

But most of the people present did not have a tacit understanding, they just looked at her curiously, and no one responded.

At this time, Sir Fang seemed very important beside her, and he replied very naturally:

"You mean the murderer went from North New Territories to West Kowloon, and the [target] and [exclusion items] changed? "

Jiayi immediately raised her thumb and made a very surprised expression:

"That's right! Sir Fang said exactly what I thought."

"..."

"..."

A table of detectives were dumbfounded when they saw Fang Zhenyue and Yi Jiayi talking about the case.

Aren't criminal investigation meetings always dull, with sad faces and frowns, and low pressure?

They have never seen a team with such a harmonious atmosphere when discussing a case. In particular, the reserved nod of Inspector Fang after being praised was simply more dazzling than a peacock spreading its tail... No! The working atmosphere of the Serious Crime Unit cannot be so full of vitality!

"The murderer started from Sheung Shui in the north of the New Territories, along the eastern area of ​​the New Territories, all the way south. During this process, the environment has undergone tremendous changes.

"We have actually pointed out just now that the murderer killed people to satisfy his own desires, sexual desire, appetite, and the desire to survive (avoiding the police and avoiding young people). But for a person to survive, the four basic necessities of food, clothing, housing and transportation must be met.

"The bicycle that Sir Wang found yesterday is 'transportation';

"Stealing food and stealing money are both 'food';

"As for 'clothing', we currently have no means to determine whether the murderer stole the victim's clothes. But at least we can be sure that the murderer must have clothes to wear, which is easy to solve. Just steal, or keep wearing your original clothes.

"There is another point we cannot ignore, that is 'housing'. The murderer killed from March to June, he needed a place to shelter from the wind and rain, there are many wilderness environments in the New Territories, and there are many abandoned houses for him to hide, and he could always find such a place to live.

"But in Sham Shui Po, the population density is very high, and the sheds in the corners of the alleys are all owned by scavengers and other owners. It is difficult for him to find a place to live without being noticed. After the Shek Kip Mei house-smuggling case, the police began to impose martial law, with uniformed police patrolling during the day and PTUs on night shift at night. Patrols will be stepped up in parks, under bridges, and in wastelands to hunt down suspicious unemployed and unidentified people.

"It is actually very difficult for the murderer to find an outdoor, stable and secluded residence that does not belong to anyone like before.

"Unless he has relatives here, he will have to worry about his own accommodation. Otherwise, he will soon become absent-minded and emotionally broken due to lack of sleep and other reasons. We don't need to catch him, he will reveal his true colors."

"Oh, I see." Wang Jiewang suddenly clapped his hands.

Everyone looked at him, and Hugo also turned to look at Sir Wang: Wow, Inspector Wang was tamed by Yi Shazhan so quickly, and he became "Inspector Fang" so quickly.

Look, Fang Zhenyue wanted to take the conversation, but he couldn't get past Sir Wang.

"Sir Wang, tell me." Jiayi immediately said with interest.

"When the murderer chose his victims in Sham Shui Po, was it possible that he chose that kind of... freelancer? The kind of people who don’t need to go to work every day and won’t be discovered immediately even if they disappear for a while?” Wang Jiewang couldn’t help frowning as he spoke. After imagining for a while, he continued:

“After arriving in Sham Shui Po, he had nothing to do all day. He used the stolen money to buy some convenience foods while looking for the next family .

“Office areas like Mong Kok definitely won’t work…”

Wang Jiewang took out the map of Sham Shui Po and stared at it:

“Some stay-at-home dads, authors, painters, photographers, paparazzi, etc… don’t seem to be very easy to find.”

Jiayi patiently watched Wang Jiewang frown and mutter while thinking, and did not interrupt him to give her answer.

"Some shops can temporarily post a notice outside the door saying that they have something to do at home and need to take leave to go home. This will not be discovered in the short term. It is best to go to restaurants with young women at home and sufficient food..." Wang Jiewang raised his head and frowned, saying,

"Do we need to issue a special warning notice for restaurants and other shops? Or send more plainclothes officers to monitor some less well-known family-owned small restaurants?"

"I think what Sir Wang said is absolutely right!" Jiayi immediately raised her thumb and said,

"Sir Wang, maybe we can narrow the scope a little bit."

"You say." Wang Jiewang looked up at her intently.

They went back and forth to advance the discussion, and the atmosphere was extremely harmonious.

Even the other detectives were shaking their maps, trying to figure out the killer's whereabouts or find the killer's next target.

"Ah! I know!" The sergeant who had just questioned whether it was meaningful for everyone to discuss the killer's psychology suddenly said loudly.

After attracting everyone's attention, he stretched out his finger and said eagerly and excitedly:

"Bicycle! It is a place that can be reached by bicycle! Or at least a place that is easily passed by when riding a bicycle from Shek Kip Mei to the south, and a place that is easy to reach."

"When patrolling, you can try to look for bicycles around restaurants, small convenience stores and other food shops. If you find them, you can identify the murderer. If you track the murderer's target nearby, you can even catch him in the act. Even if he has rubbed off his fingerprints, at least he won't be embarrassed during the interrogation stage."

You Zhaohua Shazhan on the other end of the phone couldn't help but speak loudly and quickly.

"You can give priority to searching restaurants and convenience stores outside of motorways and roads that are not open to bicycles. When searching, you can also remind the owners of these restaurants and small convenience stores to report to the police immediately if they find a man who fits the murderer's profile." Inspector Zhang Feng of the West Kowloon CID A Group on the other side of the phone also added.

"Some mobile vendors also need to be taken care of, as the murderer may also follow them home." Jia Yi added.

"I will mobilize manpower to implement this task." Because the murderer is likely to be looking for the next target in Sham Shui Po, Yau Ma Tei and other places in West Kowloon, Inspector Zhang Feng of the West Kowloon Serious Crime Unit, who is in charge of that area, took the task first.

Fang Zhenyue said to the phone: "Sir Zhang, if you are short of manpower, you can also mobilize the agents of Group B."

"OK, thank you Sir Fang." Zhang Feng finished speaking, and there was a rustling sound from the other end of the phone. It was obvious that Zhang Feng had already carried out the task with great force.

For a moment, the police officers on both sides of the phone smelled a hint of blood rush.

After 2 minutes of silence, several officers looked at Yi Jiayi at the same time. The content of their eyes was completely different from the meaning of their scrutiny when she just entered the door.

There are some people in this world who, like war drums, are born with the ability to boost morale and mobilize soldiers.
