After the detectives returned to the Yau Ma Tei Police Station, Qiu Susan came to talk to Fang Zhenyue about the deployment arrangements of the two mobile force teams she had transferred to. After she finished talking, she was about to go back to continue to work on other things, but Fang Zhenyue pulled her aside and asked her for a new task:

check all the residents in the houses that could see the windows of Gu Xiaolan's old residence in the past two years.

And asked that this list include all the information of these residents, such as photos, height, age, marital status, work status, education, etc.

So that it can be provided to Tannen for screening by comparing with the profiles he made.

Qiu Susan closed her eyes and sighed for a long time, but still patted Fang Zhenyue on the shoulder and went to work as ordered, while the other detectives returned to the B team office.

Everyone found a chair to sit down, and no one spoke for a while because they were tired.

Fortunately, the iced coffee that Qiu Susan ordered for everyone in advance arrived at this time. The weather has warmed up recently, and iced coffee is back with everyone.

The iced coffee is sweet at first, then bitter and sweet again. It is icy and refreshing, and the effect is amazing.

The agents drank refreshing drinks while eating afternoon tea. After

the pineapple buns went down their stomachs and the coffee entered their brains, everyone finally became energetic.

Uncle Jiu was paralyzed in the chair, chewing on his small wooden stick, looking up at the ceiling and sighing loudly.

Tannen was fortunate to taste the "Yi Ji Love Afternoon Tea" with everyone, and felt a little bit of the happiness of being integrated into the team. Sitting in the corner to savor the little happiness, he did not rush to argue with Fang Zhenyue about any propositions and strategies.

After everyone had eaten and drunk enough, Fang Zhenyue took a deep breath, tapped the whiteboard with a marker, attracted everyone's attention, and said:

"Come on, let's reorganize all the clues from the Zhao Dongsheng case to the present."

So, the detectives who were staggering in the last moment all sat up straight.

Tannen also raised his head, spread out his pen and notebook in front of him, waiting for Fang Zhenyue to speak.

But he didn't expect that Fang Sir had just started, so he threw the marker to Yi Jiayi, then sat on a chair at the side and sipped his coffee like nothing happened. The prince was just as casual and comfortable.

Tannen raised his eyebrows and glanced at the other detectives in Group B. Seeing that they all looked like they were used to it, he followed the local customs and tried his best to appear calm and hide his surprise.

Jiayi took the marker and enjoyed summarizing and explaining the matter.

She walked to the whiteboard and drew a vertical line, writing the name of Inspector T's murderer on the left side of the whiteboard. She then drew another vertical line on the blank space on the right.

In this way, the whiteboard was divided into three parts. Jiayi left the middle area blank, wrote a small 1 on the right side, and then began to write on the blackboard:

(1) The conflict occurred at the turn of Shi Xun Road at around 18:00 on the evening of the 22nd. The forensic doctor estimated that the victim died at around 20:00. After investigation, it was confirmed that the victim was Zhao Dongsheng, and some evidence later supported this judgment;

(2) Investigate competitors, arrest everyone in the subcontracting chain, and pass it on to O-Ji to eliminate suspicion;

(3) Continue to investigate the murder clues, focusing on two people: Gu Xiaolan and Zhao's wife Chen Tingting;

(4) On the 27th, the gossip newspaper published that Gu Xiaolan was stalked by a pervert.

(5) On the 27th, Zhao Dongsheng's body was found in Jinshan, and surveillance was carried out at night, but to no avail.

(6) Surveillance continued on the night of the 28th, and Inspector T joined the surveillance of Gu Xiaolan, but to no avail.

(7) On the 29th, go to Gu Xiaolan's home for investigation.

Tannen rested his chin on his hand and looked at the words on the whiteboard, as if he was back in a foreign classroom, becoming a student in class.

"On the first day, a damaged mobile phone was found. After checking, all the incoming and outgoing phones were fine.

" "A suit with a blood hole. According to the analysis of the blood hole on the suit, the more serious wounds were close to the heart and lungs. Several clues such as footprints and blood were found at the big bend of Shi Xun Road. According to the blood type, the bleeding people belonged to the same person. This morning, I received a phone call to confirm the DNA report. All the blood there did belong to Zhao Dongsheng. Another clue such as footprints was searched globally, but the murderer has not been matched yet.

"It was confirmed that the murderer drove a mid-sized sedan.

"At Zhao Dongsheng's home at 6 Sze Hoon Road, we found Zhao Dongsheng's bloodstains, the suspect's footprints and other clues, which were consistent with the suspect's footprints found at the big bend of Sze Hoon Road.

"Starting from the murder case, Zhao's wife Chen Tingting has a perfect alibi, and has not shown any motive for committing the crime, and there is no suspicious point such as the unexplained flow of money. All previous and subsequent inquiries against her are clear.

"Gu Xiaolan also has a perfect alibi. After various inquiries, she is not suspicious like Mrs. Zhao. Other Zhao Dongsheng's lovers were checked and no suspicion was found.

"The gossip magazine published a report about Gu Xiaolan's stalking. New clues emerged in the case. Brother Sanfu and Xu Shaowei communicated with the gossip newspaper and concluded that the paparazzi followed Gu Xiaolan and found that she moved out of the luxury house bought for her by Zhao Dongsheng, and bought gossip and love letter photos from his staff. Based on the analysis of the stalker, everyone suspected that he was closely related to the murder of Zhao Dongsheng.

"Zhao Dongsheng's body was found, and the old eyewitness was clear after examination. The autopsy inferred that the murderer was taller than Zhao Dongsheng, and the wound on his chest that caused excessive bleeding and death was consistent with the blood hole in his suit. The murder weapon was a sharp weapon, but it was not any knife in Zhao Dongsheng's home. The murder weapon has not been found yet, and it is speculated that the murderer brought it here and took it away after killing the victim. "

Jiayi omitted some other useless clues, took a sip of coffee and continued:

"The clues found today need to wait for the colleagues of the Forensic Department of the Central Police Station to issue a report and test report.

"I'm done."

Fang Zhenyue nodded, and after everyone had digested most of what he had said, he turned to Tannen and asked,

"Inspector T, do you have any new ideas?"

Tannen propped up the frame of his glasses and wiped the skin on his nose bridge that was pressed down by the nose pads of his glasses. While doing these small movements, he took the opportunity to think briefly, and then he said,

"Regarding the murderer's education, I still have the same idea. Although Agent Yi Jiayi has raised objections, based on the analysis of all the clues now, although the murderer may have a mental illness, he still has strong anti-detection capabilities and should be a person with extremely high intelligence and good logical ability.

"Such a person's state should be the result of long-term training in school.

"But regarding the job he did, I had some deeper and different thoughts.

"The murderer is likely doing some work that does not discriminate against appearance, or at least has the opportunity to conceal his appearance.

"For example, taxi drivers can hide facial defects by wearing masks, and can hide body and limb defects by sitting.

"Another example is jobs such as cleaners and drain cleaners, where wearing masks can hide the face and limping will not be noticed.

"These basic jobs can cover up the defects in appearance and limbs, but when doing these jobs, the murderer cannot make use of his knowledge, and therefore feels frustrated and underappreciated."

Jiayi handed the marker to Tannen and stepped back to make way for the explanation in front of the whiteboard.

He took it with a smile, poked the frame of his glasses, and updated his blackboard writing on the whiteboard.

But on the first point, the item of short stature was crossed out, because according to Yi Jiayi's clues, the murderer should be taller than Zhao Dongsheng, so he is definitely not short.

"So my suggestion is, first of all, screen all the people who have been checked before again.

"Secondly, continue to keep a close eye on Gu Xiaolan, and based on these 6 profiles, start observing and screening all the people who appear around her.

"Finally, after Inspector Qiu Susan, Detective Gary, Detective Liu Jiaming, and Detective Sanfu get all the names, they will also screen based on the six profiles."

Tannen looked back at the whiteboard and felt that there was no problem, so he smiled and handed the marker back to Yi Jiayi, turned to look at Fang Zhenyue, and waited for Fang Shazhan's answer.

Jiayi took the marker, turned around and looked at the six profiles on the far left of the whiteboard that belonged to Inspector T's summary, and frowned slightly.

The detectives sitting in the office listened to Inspector T's words. Some tilted their heads in thought, some nodded and felt that it seemed to make sense, and some felt that it was too mysterious and very suspicious.

As the helmsman of Team B, Fang Zhenyue cannot give wrong orders. He must think over and over again to ensure that the theoretical basis and logic behind all orders are correct.

Therefore, he did not answer immediately, but pondered again which of Inspector T's six profiles can be confirmed and used as the basis for suspect screening; which are not so certain and cannot be used as the basis for suspect screening.

Tan Sanfu, who is not only impatient but also the worst, rubbed his wrinkled eyebrows. Seeing that no one spoke, he was a little angry.

When it comes to the direction of the case, can you continue to speak nice words for the sake of face?

He dropped his hands, knocked on the surface of his desk, and questioned decisively:

"Inspector T, this is too wide a scope. They say they have clues, but in fact they are just following your profile. Can we catch the murderer by 'looking' on a large scale?"

The profiling technique has not yet been recognized by Hong Kong. Is it reliable?

We have worked hard to follow and check each person one by one according to the list. Don't let it end up with nothing, or catch a bunch of innocent citizens... If things get out of hand, won't Group B still be blamed?

With such a large workload, the theoretical foundation of this theory must be very reliable.

He really has a headache.

In his opinion, it is more reliable to wait at the place where the body was buried and act according to the solid scientific evidence of his colleagues in the forensic department that "the murderer had come to dig pits many times in an attempt to bury the body. "

Even if Gu Xiaolan has to be watched, it is still necessary to find all those who behave suspiciously. Inspector T's description of the murderer's physical characteristics are just logical assumptions, and there is no core basis. What

about the kind of evidence that can be brought to court?

"Does Detective Tan Sanfu have any opinions of your own?" Tannen was not unhappy because of Sanfu's questioning, but smiled and humbly asked for advice.

Sanfu's face flushed instantly. This case was extremely difficult. He was also confused due to staying up late and being tired. He hadn't had any so-called "insights" for a long time.

He looked at Fang Zhenyue for help, then turned to look at Yi Jiayi, his eyes shouting: Why don't you say something!

Can't we abandon our previous case-handling model? Even if Jiayi would consider methods such as profiling and logical deduction assumptions when handling cases before, weren't they all based on a large amount of evidence?

Now this... How can we let this expert mess around? So anxious.

Jiayi's fingers kept spinning the marker in her palm, and her eyebrows were slightly wrinkled.

It's true that we can't mess around. Inspector T's profiling still has major errors, and they must be pointed out.

At the same time, she saw the flow image and had a lot of information about the murderer that she wanted to convey to the detectives. Now she could use "Criminal Psychology" to make a profiling to tell it.

But she couldn't just talk about profiling like Tannen did. This is not feasible in the Hong Kong police force. In addition to theory, all profiling must be based on a lot of solid evidence. Only by using evidence to infer profiling and profiling to string together evidence can everyone be convinced.

In recent months, in order to better convey the information in the flow image to everyone, she has been learning a lot of theoretical knowledge, including "Criminal Psychology". She also relied on her memories to extract and filter some of the content mentioned in the American dramas and novels she watched in her previous life -

in short, all the knowledge that can be used should not be missed.

The current situation is very suitable for extracting the professional knowledge of "Criminal Psychology" recognized by Inspector T to convince her.

And with the extraction and analysis of a large amount of evidence, other detectives will also be convinced.

However, it may not be so easy to make Tannen, an expert, not find a big loophole and convince him.

It is also necessary to sort out the logic and only show the murderer's information that can be supported by evidence. The murderer's information that is not supported by evidence must still be hidden. Moreover, knowledge and evidence must be completely integrated and complement each other in the process of narration, and cannot appear ambiguous...

Jiayi took a deep breath, and in the process of sorting out her thoughts, she began to feel a slight migraine.

But after thinking for a while, she still took a deep breath, nodded to Sanfu soothingly, and turned to ask Fang Zhenyue for his opinion.

Fang Zhenyue seemed to have expected her to have a plan, and nodded tacitly, supporting her to speak freely.

Jiayi rubbed the pen, turned her eyes from Sanfu's face to Inspector T's face, and said calmly:

"I support Inspector T--"

Hearing Jiayi's words, Sanfu frowned suddenly: How can I support it? Isn't this right?

Tannen raised the corners of her mouth and whispered to herself "Yes!" That's great.

Jiayi changed the subject:

"Some of your ideas."

"..." Tannen.

Jiayi took off the pen cap with a bang:

"Inspector T's previous part is very exciting, worthy of being a top student. But--"

She did not continue to elaborate on her thoughts, but instead wrote quickly on the empty space in the middle of the whiteboard.

Fang Zhenyue quietly pursed his lips to wipe away his smile. When he saw Yi Jiayi leaving a blank space in the middle of the whiteboard, he knew that she had a lot of her own ideas to say.

As expected of our Zhenyue, although she is not a top student like Tannen, her intelligence is probably higher than Tannen's.

The other agents were already familiar with Jiayi's style. When they saw her start, they drank coffee to refresh themselves: the brain-burning analysis is about to begin. Students, don't be distracted, don't fall behind, and keep up with Teacher Eleven's thinking!
