I went to the Central Police Station to find Intermediate Chemist Man to communicate new clues and new ideas. This job was finally undertaken by Brother Jiaming alone.

Jiayi and Fang Zhenyue went straight to Sheung Kwai Chung.

When they arrived at the destination and set up a cordon and walked into the scene, the Forensic Department team in charge of this case from the Central Police Station also arrived.

Because Man had to stay in the police station to discuss the known evidence and unknown clues with Liu Jiaming again, Senior Chemist Teresa only brought Junior Chemist Awei over.

"The body was found by an old man who went up the mountain to collect firewood. In order to cover the body, the murderer covered it with a lot of branches." The uniformed police guarding the scene saw Fang Zhenyue and Yi Jiayi rushing over, and immediately walked up to take on the responsibility of explaining the scene.

"Eleven, take a statement for the old man." Fang Zhenyue gestured.

"Yes, sir." Jiayi nodded, took out a pen and a notebook, and walked towards the old man squatting under a tree.

The old man went out at dawn in the morning, picking up branches and wild vegetables along the way. When he arrived at the scene, he saw a small hill without thinking much. He picked up a few branches on it and saw the body, so he ran back to the village to call the police.

There was no one else here when he came, and he didn't see anyone else along the way. He didn't notice any strange people coming to the villages near Kwai Chung recently.

He didn't touch anything after he found the body, and even threw the few branches he picked up on the body...

After taking the statement, Jiayi walked back to Fang Zhenyue.

The detectives had not yet approached the body. Only the medical examiner Sir Xu and another medical examiner under his command were squatting in front of the body to conduct a preliminary examination.

Teresa and Ah Wei were conducting a scene survey nearby, and everyone else was temporarily prohibited from approaching.

"There were only footprints of the old man and another person at the scene. The size of the other person's shoes matched the footprints we found in the courtyard of the villa at No. 6 Sze Hoon Road. Through on-site observation, we judged that the footprints belonged to the same person. Specific confirmation requires returning to the office for more comparisons before a report can be issued." Teresa was conducting an investigation while turning back to introduce to Fang Zhenyue and Jiayi.

"From clues such as the wetness of the excavated soil, we can infer that the murderer came to dig the pit every night, and he dug for nearly a week before he dug so deep. We cannot confirm whether he came every night in recent days, but it is very likely that he will continue to dig the pit and bury the body in the pit for the final hiding." Teresa stood up from the pit and turned to Fang Zhenyue.

Fang Zhenyue thought for only two seconds, then turned to the three uniformed police officers and said, "Remove the cordon and drive all the police cars away immediately. The discovery of the body here must be kept confidential."

"Yes, sir." The three uniformed police officers immediately started working, removed the flashing lights on the police car, and quietly and quickly drove the police car away from the hillside.

"Eleven, take the old man back to the village and make sure he keeps this a secret. Call Mr. Guo from the Public Relations Department and tell him to keep the discovery of Zhao Dongsheng's body a secret for a week, block the news from all media, and don't inform Mrs. Zhao for the time being." Fang Zhenyue said again. "

Yes, sir." Jiayi responded and then went to communicate with the old man, sent him back to the village, and called the police station to find Mr. Guo.

Fortunately, the old man had not had time to gossip with the villagers after discovering the body in the morning. The police force also responded quickly, so the news had not been spread yet, and the media had not smelled the fishy smell yet.

According to Fang Zhenyue's request, Jiayi called Da Guangming and others from the Forensic Division of the West Kowloon Serious Crime Unit to come and help. In order not to alert the media and the murderer, a group of plainclothes officers all came by bus.

When Brother Da Guangming arrived, the body had been transported back to the Central Police Station. Teresa's team also retreated to the road. Fang Zhenyue's jeep was also driven away. Basically, all the people and vehicles on the scene had retreated.

As soon as the people from the West Kowloon Serious Crime Unit Forensic Division got out of the car, they cooperated with Teresa and Ah Wei to deal with the scene: placing dummies under the branches and restoring the scene according to the shape in the photos taken when they first arrived.

Reconstructing the wheel tracks and footprints on the entire road was a lot of work and the time was very tight. The colleagues in the Forensic Division worked hard like old cows. The mountain forest was originally very cool in late autumn, but everyone was sweating profusely and their faces were flushed. It

was not until the sun set that the area looked like no car or person had been there.

The colleagues from the Forensic Investigation Department could hardly stand up straight. After finishing their work, they did not dare to stay in the vicinity for long. As other vehicles had been evacuated long ago, they had to drag their exhausted bodies and take the bus back.

Everyone was really exhausted today.

The detectives of Team B had already arranged the teams and schedules for keeping an eye on Gu Xiaolan and the burial site. In the first half of the night, Fang Zhenyue and Jiayi, wearing camouflage uniforms, kept an eye on the burial site. After eating and getting ready, they sneaked in along another mountain road. It was already very late. When

I looked up, I saw the mountains connected in the dimness, and the shadows of the trees were like the undulating sea. In the distance, there was only a hint of red light in the sky, like the hem of the sun that had not yet hidden in the horizon.

The mountains are like the sea, and the waning sun is like blood.

...

...

That night, Sanfu led people to follow Gu Xiaolan, followed her to stay at a friend's house after work, and turned off the engine to wait opposite the friend's house. No suspicious taxi drivers were seen.

The police officers who followed all the taxis that were picking up and dropping off passengers wrote down the license plates. When they returned to the police station, they looked for these drivers based on the license plates and quietly checked their driving records, income and expenditure in the past half month, but found nothing suspicious.

The team that was guarding the body also found nothing. Everyone was covered in cold dew and did not see a single hair of the murderer.

When they returned to the office to review the situation, they could not tell whether the murderer had been alarmed.

…

Jiayi caught a cold because she had been lying on the ground with Brother Yue for half the night, even though she was wearing many clothes.

After returning home, she drank several large cups of hot water and felt better after a good sleep.

When she went to Yi Ji for lunch, she found that her eldest brother had prepared a military green moisture-proof mat for her, so that she could lie on it when ambushing and squatting, so as not to catch a cold.

Sun Xin made her a pot of Xianglian chicken soup. The sandy, soft and powdery Xianglian was stained with the fresh flavor of the chicken soup, and it tasted really delicious. Jiayi ate all the Xianglian in the chicken soup and drank two large bowls of chicken soup, but she only ate one leg and one wing of the chicken.

But warming up the body may really improve the resistance.

After saying goodbye, she took the Ding-Dong car to the police station to save energy. On the way, she kept reviewing the ambush methods she learned from Brother Yue last night. Several major precautions were particularly important and she had to remember them repeatedly without neglecting them.

When she arrived at the office, she wrote them down in her notebook to deepen her understanding and memory.

Only then did Jiayi remember that she was excited to go to the scene to see the body yesterday, but she was so busy until now that she had not actually seen the body.

After taking a sip of hot milk tea, she put down her notebook, said hello to Brother Yue and everyone, and prepared to take a bus to the Forensic Department of the Central Police Station, under the pretext of understanding the progress of the forensic officer's autopsy, to see the body.

As a result, when she reached the door, she saw that the door of Qiu Susan's office was opened, and Madam walked out of the door with a somewhat unnatural and enthusiastic smile with another young and tall youth.

The young man was dressed very elegantly, with a gray plaid suit with a dark brown tie, and black pointed leather shoes that were polished

to a shine. Jiayi looked up and found that the young man's slicked back hair and leather shoes complemented each other, and both were so shiny that they were dazzling.

Qiu Susan and Jiayi looked at each other for a moment, raised their eyebrows and squinted their eyes, then led the young man into the office of Team B and solemnly introduced him to everyone:

"Patrick, come on, call everyone over, and introduce an expert to everyone."

Jiayi stood at the door and looked at the young man. The other nodded at her reservedly, and then walked into the office with his head held high, as proud as a big rooster patrolling his territory.

Jiayi turned around to look at Fang Zhenyue, and saw that he nodded to her, so she turned back to the office and found a seat to sit down.

All the agents in Team B stopped their work, looked up at Qiu Susan, and looked at the expert mentioned by Madam one by one.

Liu Jiaming, who was deeply influenced by Fang Zhenyue's luxurious clothes, immediately recognized that the expert's suit, leather shoes, shirt and tie were all branded, and he looked like a wealthy top student.

Fang Zhenyue walked closer, Qiu Susan nodded, and introduced him to the expert:

"This is the one I just told you about, CID B Group Sergeant Fang Zhenyue, who is also one of our CID's best detectives, who has made outstanding achievements and has been our MVP in solving cases for many years."

The expert smiled and took the initiative to reach out and shake hands with Fang Zhenyue.

Qiu Susan then said to Fang Zhenyue:

"This is a criminal psychologist who just returned from studying in the UK, Tannen.

"He is also a criminal psychologist in the police force who was hired by the superiors with a lot of money. Now foreign countries are conducting in-depth research on the role of profiling in case detection. There are already some cases that prove that profiling can greatly assist criminal investigation work--"

"Just call me T. "Tannen smiled and nodded to Fang Zhenyue and everyone else. Even though he softened his voice, his fast speaking speed and the rhythm of his voice showed that he was efficient and in control.

After Qiu Susan's introduction, she told the reason why T came to Group B this time:

"The murder case of Zhao Dongsheng that our Group B encountered this time is special. Sir Huang thinks it is appropriate to invite expert T to join the team. It will be a new opportunity for us to solve the case and help us find new breakthroughs.

"So starting from today, T will join the investigation of the Zhao Dongsheng case. I hope everyone will actively cooperate with T's work and learn more from T--"

Qiu Susan paused here, smiled incomprehensibly, and then continued:

"Advanced detective science."

Although Qiu Susan's wording was very skillful, everyone still heard the hidden meaning.

Huang Sir thought that their speed in solving the case was too slow this time. He was worried that a public figure like Gu Xiaolan would really be attacked by the murderer. At that time, the police force would be very embarrassed and it would not end well.

So this expert who had returned from studying in the UK was sent to participate in actual combat and accumulate experience. Of course, the main purpose is to guide everyone's work and introduce high-end technology in the criminal investigation work of Group B this time.

The detectives, who had been working for days and nights, all had dull expressions on their faces. They stared at Tannen expressionlessly, which was definitely not welcoming.

First of all, everyone would instinctively reject someone who challenges their own investigative methods and habits.

Secondly, this case was solved slower than in the past, but it was definitely not slow in the entire CID! Sir Huang treated everyone with an unusual attitude. It would have been fine if he had encouraged everyone, but he also put pressure on everyone because this case involved big shots and public figures like "Millionaire Zhao Dongsheng", "Millionaire Zhou Xinhui", and "Celebrity Gu Xiaolan".

He also sent a scholar who was good at talking about military affairs on paper to instruct everyone. It would be strange if this room full of soldiers could obey this scholar.

Tannen took a look at the reactions of the detectives and knew that he was not welcome.

Although he was a top student who had studied abroad, he was not naive enough to think that everyone would naturally come to welcome him.

After scanning everyone, he turned around and briefly read the phrases on the whiteboard, then turned around and smiled at everyone:

"Madam Qiu has already briefly introduced this case to me. I can see that everyone has worked hard during this period.

"Although Mr. Huang said that he wanted me to bring in advanced technology, it is actually just some theoretical knowledge to add icing on the cake. There is no such thing as a panacea in this world. I don't think foreign monks are better at chanting sutras. We can all learn from each other.

"I actually understand what Mr. Huang meant. In fact, he still wants me to be on the front line, learn more from everyone's practical experience, and study how to integrate foreign criminal psychology, profiling and other content into criminal investigation work."

After Tannen said this, everyone finally felt more comfortable, their expressions relaxed, and a little softness appeared on their tired faces.

Tannen hurriedly struck while the iron was hot:

"Especially with Fang Shazhan leading everyone, they have quickly locked on the victim and have a direction for the murderer.

"I have observed the British handling cases abroad, and it is rare to see such high efficiency. Our Hong Kong detectives are actually advanced on a global scale.

"Of course, if I can really use what I have learned and it can have even a little positive effect on the police solving cases, it will be an honor."

Fang Zhenyue took a step back, exchanged a glance with Qiu Susan, and sat on the chair looking at Tannen leisurely, waiting for him to finish his long speech and what he was going to say next.

Sure enough, Tannen saw that everyone's expressions were gradually relaxing and their body language showed that their defense against him was decreasing. Finally, he smiled and stood in front of the whiteboard and began to talk about some of his other thoughts on the case:

"Everyone wants to do good for this case, and this is also the purpose of my coming here.

"I won't say any more nonsense, let's get back to the case.

"The so-called love letter that Miss Gu Xiaolan received has been published in gossip newspapers. According to the analysis of criminal psychology, the murderer is very likely to be enraged. Miss Gu Xiaolan's life safety is now under great threat.

"Although the squatting method we are using now is not easy to alarm the murderer, I think it still has considerable loopholes.

"First of all, we have limited staff, and we are not able to ensure that we are always with Miss Gu Xiaolan. What if she goes to the bathroom in a building or other environment outside her home, or the detectives do not investigate for a while, and the murderer takes advantage of the opportunity, the consequences will be disastrous.

"That will be the price of life!"

Tannen tried his best to make his expression without any blame, and acted in a businesslike manner:

"I still suggest that everyone hold another meeting to discuss all the people who appeared in this case, including all the taxi drivers who passed by Gu Xiaolan's residence when picking up and dropping off guests after the stakeout yesterday.

"I will make a character portrait of the murderer based on the existing information, and then we will see if there are people who fit the portrait among the people we are paying attention to now.

"On the other hand, I will also make a geographical portrait based on the existing clues. Oh, geographic profiling is a scientific investigative tool that can deduce the murderer's next crime scene. It can help detectives determine more appropriate surveillance areas and patrol densities during the case-solving process. "

Qiu Sushan has been paying attention to foreign literature on criminal psychology, psychological portraits, geographical portraits and even psychological autopsies. She always feels that it is mysterious and mysterious, and she is inevitably a little dissatisfied. Listening to Tannen's words, she is actually not very interested.

Uncle Jiu has already chewed a wooden stick and sunk into the chair, closed his eyes and dozed off.

But Jiayi and Fang Zhenyue listened carefully, showing that they were interested in what Tannen said. If there is a science that can outline the murderer's education, appearance, personality, family status and other information through the investigation of the crime scene and the analysis of evidence, then Fang Zhenyue will take a wait-and-see attitude on this matter, but he also sincerely hopes that what Tannen said is true, and Jiayi

will definitely welcome anything that is useful in solving the case.

In her previous life, she had watched too many movies and books related to foreign criminal psychology, which exaggerated the profiling and criminal psychology of foreigners. She wanted to learn more about foreign knowledge in this area in the 1990s through Tannen, and see how accurate it was.

Liu Jiaming, who was sitting behind Fang Zhenyue, also looked up. Nowadays, American dramas and movies often feature high-sounding content such as "criminal psychology", "psychology", and "multiple personality". As long as the protagonist masters this technology, he will basically be invincible and feel particularly cool, like Hannibal who loves to eat people in "The Silence of the Lambs", and Sharon Stone and the detective in "Basic Instinct". They either rely on criminal psychology to solve the case, or are manipulated by the criminals with advanced psychological skills...

I don't know if it's really that awesome!

Tannen saw that some people showed interest in what he said, especially Jiayi who even took out a small notebook to take notes. He immediately smiled and asked Fang Zhenyue:

"Can I erase the whiteboard and make some notes?"

"Please." Fang Zhenyue nodded and gave up the authority generously.

Tannen turned around and wiped the phrases and words on the whiteboard clean, and wrote from the left side:

1. Special physical characteristics, such as obesity, short stature, buck eyes, early hair loss, etc.;

2. Unmarried, no stable opposite-sex relationship;

3. Male between the ages of 20 and 35;

4. There are clues of escalating violent behavior before the murder, such as killing small animals;

5. Not low education: high school graduate (junior high school consecutively);

6. He may not be a taxi driver, but a car owner who is posing as a cleaner.

Liu Jiaming watched Tannen quickly write down 6 points of judgment on the murderer, even including the other party's appearance and education. He unconsciously pursed his lips and tilted his head, showing a confused and surprised expression.

Uncle Jiu was drowsy at first, but after seeing these 6 points, he couldn't help but turn his head and whisper to Yi Jiayi: "He seems a bit like you? Can we tell so many things from the current clues? "

He smacked his lips. He had thought that Shiyi was very weird before, but now it seemed that he had really misjudged Shiyi. In fact, it was not weird, but just a science.

Jiayi turned around and looked at Uncle Jiu, also a little confused. The policewoman who always made others look confused, rarely played the role of a confused person, and asked curiously:

"Inspector T, how did you make this judgment?"

These 6 points were completely different from many of the conclusions they had made before. Which one was true and which one was false?
