In the morning, Jiayi reviewed the past few months with everyone in the B team office, and went to Yue's office to talk to him about many details of the New Territories North Misfortune case, and also talked to Yue about the dozen questions she had written in her notebook.

Since the special task force has not yet been established, Yue is not very familiar with many circumstances of the case. In addition, he is a very cautious person and does not speculate on the case. Jiayi had to suppress her curiosity and wait for the establishment and summons of the special task force.

At noon, everyone had a light meal at a restaurant downstairs, and then took a nap on the table. After waking up, they looked at the old case files. At about 3 pm, Superintendent Wong finally called Fang Zhen Yue's office.

After hanging up the phone, Fang Zhenyue grabbed a piece of paper and a pen, and stepped out of the door and walked to the opposite side. He raised his finger to Jiayi who had been waiting for a long time, and took Yi Shazhan who had put a piece of paper and pen in his pocket.

The two of them then walked side by side with their heads held high and walked towards the conference room along Eleventh Road.

Jiayi walked very fast on the way, and couldn't help but say to Brother Yue:

"The time required to walk from Sheung Shui to Fanling should be roughly estimated, and then compared with the time the murderer committed the crime, and then calculate the time from Fanling Road to Tai Po, and then calculate from Tai Po to Ma On Shan... If they are all similar, can we estimate the time the murderer committed the crime based on the time he took to walk from the last crime scene to the next crime scene?"

Fang Zhenyue turned around and smiled at her, "You're getting into work mode so quickly?"

"Of course." Jiayi nodded.

The two of them then chatted about the case and walked into the conference room one after the other.

The person presiding over the meeting today is Neil Sir, Assistant Commissioner of Police of the Hong Kong Police Force. The middle-aged officer has a standard square face, thick eyebrows, big eyes, a broad nose and thick lips. He is ugly, but his eyes are sharp, which makes people dare not look down on

him. Sitting below him are the Chief Superintendent of New Territories North CID, several inspectors in charge of the door-breaking case, and Chief Superintendent Wong Sir of the West Kowloon Serious Crime Unit, and three inspectors under him who have no cases to handle for the time being, including Inspector Zhang Feng of Group A.

After Fang Zhenyue and Jiayi walked into the meeting room, they simply scanned everyone in almost exactly the same movements.

After Fang Zhenyue greeted Neil Sir and Huang Sir, he introduced Yi Jiayi Shazhan to everyone. After he finished speaking, Jiayi immediately gave a neat hand-flip salute.

When Jia Yi followed Fang Zhenyue to take their seats, everyone around them turned around and looked at Sergeant Yi Jia Yi expressionlessly. This youngest female sergeant had made many achievements last year and was somewhat famous in the police force. If this "aura" could be stabilized for a few years and her ability and reputation could be consolidated, then at this age and on this trend, she would probably be much more promising than everyone else present. She

became famous too early, and while she was expected, she would also be subject to equal scrutiny.

Would she run out of talent, suddenly be known as a genius, and then suddenly fall? Or would she really keep pushing forward, climb higher, and go further?

Jiayi calmly accepted the scrutiny of the superiors. After sitting down, she spread out her notebook, held a pen and lowered her head to read her notes. She ignored everyone and seemed particularly calm and composed.

Not long after, expert Tannen arrived. After he entered the room and greeted the superiors, he deliberately bypassed the long table and sat on the other side of Jiayi. He smiled and whispered a few words to her.

Immediately afterwards, the superiors of the Forensic Department and the Forensic Investigation Division of the New Territories North Serious Crime Unit in charge of this case also arrived.

When the forensic officer Xu Junhao of the West Kowloon Serious Crime Unit walked in, he looked around and saw that the seat next to Jiayi was occupied by Tannen, so he had to sit next to Fang Zhenyue. After sitting down, he even poked his head around Fang Zhenyue and waved to Jiayi.

Because there were too many senior officers present, Jiayi was reserved and did not smile too brightly. She just winked at Xu Sir and waved her hands slightly.

Fang Zhenyue glanced at Xu Junhao on the left and Jiayi on the right, leaned forward, and rested his elbows on the table to block the small interaction between Jiayi and Xu Junhao.

When Chen Guangyao from the Forensic Science Department walked in, although he sat opposite Jiayi, he also smiled and waved to her.

Everyone who was familiar with Jiayi greeted her as cordially as if they were friends. It can be seen that they not only respected Sergeant Yi Jiayi as a colleague, but also had some more cordial feelings.

Neil Sir, who was sitting next to Superintendent Huang, whispered, "Your little sergeant is very popular."

"A truly talented detective." Superintendent Huang nodded and praised Yi Jiayi to his superior. There was a star detective who was frequently reported in the newspapers in his West Kowloon Serious Crime Unit. He was honored to be one of them, and it was also an opportunity to show his face in front of his superior.

"The new generation in the team is well trained." Neil Sir nodded again.

"Thank you, sir." Huang Sir was praised and immediately smiled proudly and reservedly.

Sitting opposite, Chief Superintendent of New Territories North, Au Chu-ho, glanced at Huang Sir's expression, turned his head and glanced at Yi Jiayi, and raised his left eyebrow almost unnoticeably.

At 3:15, everyone was present and the meeting officially began.

Neil Sir did not waste his words and directly made the decision that the task force would be established in this meeting room today. Everyone present would belong to the task force think tank.

The team led by each inspector present would automatically enter the task force, and each serious case team would be numbered in turn. The West Kowloon Serious Case Team B led by Fang Zhenyue was Team No. 6.

The number was very auspicious, and Jiayi liked it very much.

After each task was assigned, the team leader (that is, the inspector of the team) would lead the team to handle it. In the subsequent task force briefing, only the team leader would participate and report the progress.

Since the first door-to-door murder occurred in the New Territories North, Inspector Wang Jiewang of the New Territories North Serious Crime Unit B Team, who was the first to take charge of the case, followed up the longest and obtained the most comprehensive information, served as the head of this think tank, responsible for the arrangement, follow-up, summary and inspection of the work of all team members.

Finally, he reported to the chief of this task force, Assistant Commissioner of Police Neil Sir of the Hong Kong Police Force.

During this period, everyone in this team was only responsible for this case, and other work was assigned to other colleagues.

Because the case had a very bad impact and greatly damaged the personal and property safety of citizens, and the murderer was still active in the crowd and could continue to commit crimes at any time, all members of the task force must do their best to cooperate in solving the case.

"I set a deadline of 45 days to solve the case. Do you have any objections?" Sir Neil set a deadline for the team members after he set up the task force.

No one at the long table said anything. Jiayi silently wrote the number '45' on her notebook.

After everyone stared at each other for a few seconds, Chief Superintendent of New Territories North, Au Chu-ho, could no longer sit still. This case started in the New Territories North. He investigated for three months but failed to catch the murderer. As a result, the case spread from the New Territories North to the New Territories South and then to West Kowloon. The murderer was let go right under his nose. It was precisely because he failed to solve the case quickly that the murderer became more and more rampant and more and more skilled...

Even if the case was solved as scheduled in the end, he, the Chief Superintendent of New Territories North CID, would still be held responsible.

Moreover, it is already very difficult for a stranger to commit a crime on the move, and the possibility of not being able to solve the case on time is also very high. If everyone takes the blame, the responsibility he has to bear will definitely be heavier and greater.

So, with his hands on the table, he turned his head to look at Neil Sir, put on a bitter expression, and said in a deep voice:

"Neil Sir, I think 45 days is too difficult."

Neil Sir turned his head and put on an expression that said "I'd like to hear more details."

"In recent years, it is difficult for the major cases encountered by the major crime teams in various districts to be solved within 45 days." Ou Zhuhao put down the pen in his hand and began to recount the past:

"When we set up a special task force for the Kwai Chung murder case, it took more than a year from the filing of the case in April 1998 to the investigation, arrest and trial.

"The Rainy Night Butcher case was filed in February 1993, and the murderer was not found until August 18. It was because the clerk of the photo studio found something wrong with the photo and called the police. The police found that it was related to the Butcher case and solved the case indirectly and accidentally. It also took 6 months.

"The Tuen Mun sex maniac case took one year and four months from the filing of the case on April 24 of the previous year to the arrest of the murderer in August of the following year. The case was solved because a victim who was raped but not killed reported the case, which gave the police the opportunity to establish a connection with the murderer through the victim. The murderer was ambushed and arrested when the murderer made an appointment with the victim to watch a movie."

It takes a few months or even years to solve a major case.

The police officers present at the meeting looked heavy-hearted as they listened to Ou Zhuhao's examples.

With limited technology and police force, the police often feel stretched when solving major, strange, and special cases.

This is really infuriating and shameful, but it is indeed the current situation.

Jiayi frowned and raised her head after writing down several cases mentioned by Ou Zhuhao. Even in the future with advanced technology, there are still many unsolved cases every year, let alone now.

This is probably the reason why many policemen look old even though they are just entering middle age. It is very arduous to carry unsolved cases, which is too tiring for both body and mind.

"Neil Sir, our case has many difficult elements such as 'strangers handling the case', 'random victim selection', and 'random crime location'..."

"We will of course try our best, but we still need to be more relaxed. "

Ou Zhuhao's voice was filled with a bit of pity and powerlessness.

Sir Neil frowned with empathy, and said solemnly:

"The Public Relations Department is also under great pressure. The image of the police force is at stake. They need a deadline to make a promise to the citizens so that the citizens will have an expectation and know that we are racing against time and are determined to catch the murderer within a certain period of time."

Sir Neil sighed and said helplessly:

"I will talk to the Public Relations Department again and ask them to make some other commitments without mentioning a deadline for the time being.

"But you should speed up the progress this week, preferably on Friday, and give me a specific time point.

"This is what we must explain to the citizens."

"...OK, sir, we will discuss a time together. "Ou Zhuhao sat upright, his eyes full of gratitude to his superiors.

As long as he complained about his suffering, the failure to solve the case in the previous three months would become excusable, and the heavy stone on his chest was finally relieved.

In the next meeting, Ou Zhuhao called on the head of the "think tank", that is, Inspector Wang Jiewang, who was the first to take over the case in the New Territories North Serious Crime Unit, and his sergeant Hugo, to make a detailed report on all the current situations of the "serial murder case".

So, one by one, the reports of the Forensic Department, the reports of the Forensic Department, the logical chains of the New Territories North CID detectives, and a large amount of clues and information were shared with everyone at the long table.

Together with various report forms and document copies, they were also distributed to everyone separately. in her hand.

Jiayi listened to them one by one and found that the general situation was similar to what she had summarized from the information she had collected before.

The inferences of many detectives from the New Territories North Serious Crime Unit also coincided with what Jiayi had thought.

Unfortunately, most of the questions she listed, the detectives who had handled the case before were unable to find evidence and come up with definite answers. There were too many unresolved issues, and the information was too complicated and it was unclear whether it was useful or useless.

When the information was shared in the second half, Jiayi's brows were almost twisted into a knot.

This case has been handled for 3 months, but most of the evidence and clues cannot be connected. They each lived on a hill and looked at the detectives indifferently as they were exhausted. This was really a very bad situation.

No wonder Ou Zhuhao was unwilling to accept Neil Sir's deadline, because now there is no end to the tangled mess. A super major case is still in the initial stage of investigation, and the time for solving the case, of course, seems to be a long time.

It is a despairing cognition.

In the process of listening to the sharing, not only Jiayi got the current situation, but also Chief Superintendent Huang Sir of the West Kowloon Serious Crime Unit couldn't help gritting his teeth.

When he turned his head to look at Chief Superintendent Au Chu-ho of the New Territories North Serious Crime Unit, his eyes unconsciously showed a hint of disapproval. Au

Chu-ho happened to look up and met Sir Huang's line of sight, and instantly received the message in the other's eyes: What are you doing in the New Territories North? The case is simply a mess!

"..."

Ou Zhuhao's breath got stuck in his throat, his face darkened, and his eyes shot back coldly. Then he glanced at several inspectors from West Kowloon with disdain, and his meaning was obvious: Don't look down on people, you people from West Kowloon may not be detectives.

"...The murderer committed the crime purely for money, women and food. It can be judged that he cannot work in Hong Kong to earn money. This is consistent with our previous 'the murderer is a foreign illegal immigrant with no household registration and no identity certificate'.

"Since the second murder case, all buses and taxis in the New Territories have been required to check the identification of passengers, and checkpoints have been set up at various intersections and important activity areas to check the identification of drivers, passers-by, passengers, etc. No suspicious persons were found.

"Based on this, the murderer walked all the way south.

"This is consistent with the interval between the murderer's crimes and the distance between the crime scenes.

"The only difference between Case 3, the murder case in Tai Po, and Case 4, the murder case in Ma On Shan, was only three days.

"The police suspect that the murderer took a boat to Ma On Shan, or got to Ma On Shan by stealing a boat, so we have been looking for boats that may have carried the murderer on both sides of the strait, as well as families whose boats were stolen."

Hugo Shazhan, who was reporting in the northern New Territories, said nothing and took a sip of mineral water.

At this time, Jiayi raised her head, turned her head and glanced at Fang Zhenyue, and asked in a low voice: "Can I interrupt and ask a question?"

"Ask." Fang Zhenyue said nonchalantly. In his opinion, this place is no different from the B team office. Ask whatever you want to ask and chat whenever you want. This is how the task force should behave.

Jiayi raised her head and said politely,

"Sergeant Hugo, I want to ask a question at this point."

Most people at the long table raised their heads and looked at Yi Jiayi together with Hugo.

"Excuse me." Hugo turned his head and glanced at his superiors. Seeing that no one had any objections, he nodded.

"In Case 3, the Tai Po massacre, is there a list of lost items in the victim's home?" Jiayi had a guess, but she needed confirmation.

"Because we can only judge what may be missing from the victim's home through the on-site investigation of the forensic department. Or make judgments based on the testimony of the victim's relatives and neighbors, so many conclusions are uncertain." Hugo flipped through the documents in his hand, found the form for lost items in Case 3 that they integrated through the testimony and the report form, and leaned forward to hand it over.

Jiayi frowned after flipping through it, but unfortunately the form did not have what she thought. It seemed that she could only go to the victim's home in Case 3 to take a look, or use the flow imaging, or visit the vicinity of Case 3...

"Yi Jiayi, what are you looking for?" Superintendent Huang saw her frown and simply asked her what she thought.

If anyone else had made such a reaction, Sir Huang might not ask.

But this person is Yi Jiayi, the Yi Jiayi who always has a unique way to solve a case. Since she looked confused and made specific requests, she must have some idea.

Even if it was just an idea, he wanted to hear it.

"Oh, that's it, Mr. Huang."

Jiayi looked at the notebook in front of her, and then looked at Fang Zhenyue and Tannen beside her. Then she mustered up the courage and said aloud:

"From the details of the murderer's multiple cases, it can be seen that the murderer has a habit of looting some things from the victim's home in the previous case, not only to fill his stomach and wallet, but also to find handy tools to commit crimes.

"Including the fact that no fingerprints were found at the scene of the Shek Kip Mei house-massacre case in Sham Shui Po, we also inferred that the murderer may have stolen rubber gloves and other suspicious items that could conceal fingerprints from the previous family.

"So, I was wondering if it is possible that the murderer stole some kind of tool from the homes of the three suspects, or from the homes of the residents between the homes of the victims in case 3 and the homes of the victims in case 4?

"For example, a bicycle, a motorcycle, or a car, and then used the stolen means of transportation to get from Tai Po to Ma On Shan within three days. "

If the murderer stole the means of transportation from the homes of the three suspects, then at least the police can save manpower and no longer need to investigate the thefts of boats and the boats that may have carried the murderer.

"If the murderer stole the means of transportation from a house between the two crime scenes, then not only can manpower be saved, but new witnesses may also be discovered, or new ideas and directions may be found.

"Of course, I'm just guessing at this stage."

"Ah... We did check the vehicles of the victim in case 3 and confirmed that nothing was lost. But we didn't think about whether other families lost vehicles along the way." Hugo lowered his eyes and thought for a while, then suddenly took off the pen cap with a snap, made a note on the notebook at hand, and then turned around and said:

"This is easy to check. I'll make a phone call now and ask the detectives in our team to check all the thefts of vehicles near the home of the victim of the Tai Po family murder case to the home of the victim of the Ma On Shan family murder case."

Hugo stood up and said hello to his superiors, then hurried out of the conference room.

As soon as the reporter left, the conference room instantly became quiet.

Hugo's inspector picked up the documents Hugo put down and prepared to continue reporting.

But before he opened his mouth, he couldn't help but look at Yi Jiayi first, with a curiosity in his eyes that was not there before. She

had just come into contact with this case, and she immediately constructed a logical chain and had her own ideas. She

is indeed quite capable.

And Superintendent Huang, who was on the left side of Neil Sir at the long table, couldn't help but nod to Jiayi in admiration, and then turned to raise an eyebrow at Ou Zhuhao:

Who knows, maybe we really have a detective in West Kowloon.

"..." Superintendent Ou Zhuhao.

Grinding teeth, unwilling, but temporarily unable to refute.
