Six, why six?

After Jiayi came to her senses, she tried to regulate her emotions by taking deep breaths, calming herself down, and facing the complex case in the most rational state.

This was the method that Dr. Bai taught her during the psychological counseling after the shooting. Try to calm your emotions, don't think about things that trigger fear or other emotions, and let yourself focus on some logical content, such as thinking about the formula 1+1=2. After diverting your attention and calming yourself down, use rational logic to return to the things that triggered the emotions and redefine the matter, which helps to calm the pain, reduce fear, and solve the problem.

It worked very well. After silently repeating '1+1=2' for a while, Jiayi calmed herself down quickly. She heard Brother Da Guangming standing beside the bed and discussing the strange appearance with the medical examiner Xu Junhao:

"It doesn't look like a wound caused by a dagger. You can see that it has a saw-like shape. When I was doing the on-site investigation just now, I only took a quick glance and I thought it was very strange."

"Yes, if it was a dagger, the wound should have one cut on each end because it was torn and cut. Some wounds will have two cuts on each end because when a person pulls out a dagger, the knife path may be changed. But this wound has many cuts on both ends. It may be a strange weapon with fine saw blades on both ends, or the murderer kept cutting while killing people. But why did she do this?" Sir Xu frowned. In previous autopsy cases, such wounds had indeed never been seen.

Jiayi frowned and took a step forward, pretending to look at the wound carefully. After a few seconds, she turned to Xu Junhao and said,

"Isn't there another possibility that the murderer inserted the knife fiercely for the first time, then pulled it out and stabbed it again fiercely. In fact, the murderer stabbed several times continuously to vent his anger or to ensure the death of the victim. The only difference from stabbing several times to kill people is that this murderer stabbed in the same place with each knife."

Xu Junhao was stunned for a moment, and unconsciously uttered "hmm..." thinking sound, while turning back to check the wound again, and looked up after more than ten seconds, "What Jiayi said is very likely! After taking it back to the forensic autopsy room, we can conduct an in-depth study of the wound section during the autopsy based on this conjecture."

"Thank you for your hard work, Sir Xu." Jiayi took a step back.

"But why did the murderer do this?" Liu Jiaming walked behind Jiayi and frowned in confusion.

"There is also a blunt weapon wound on the back of the deceased's head. It is possible that this is the fatal injury." Sir Xu continued to conduct a preliminary on-site inspection of the body. "

A blood-stained crystal ball was found on the small shelf at the door. After returning to the police station, we will focus on extracting and testing its attachments, fingerprints, etc." Brother Da Guangming immediately answered.

Jiayi turned around to look at the crystal ball that Diane had collected in the evidence bag. It was basically the same as the thing that the murderer saw in the heart flow image, which was held in the palm of his hand and hit Zhao Meini on the back of the head.

It turned out to be a crystal ball.

Sir Xu raised his head and nodded to Brother Da Guangming, then looked at another part of the body:

"The murderer may have brushed the body... There are no signs of assault. Whether there were other evil deeds before the murder, we need to return to the police station to extract other contents... The preliminary judgment is that the victim was hit on the back of the head with a blunt object, and then the stabbing was carried out..."

"The stabbing may also be for venting anger." Uncle Jiu leaned against the door and sighed lazily.

"The blood-stained crystal ball was found on the shelf in the living room. It was simply cleaned by someone, probably using disinfectants and other chemicals. The murderer wiped off the fingerprints, but left blood stains." Diane, a chemist, supplemented.

"Then the blunt weapon hitting the head most likely occurred in the living room." Uncle Jiu turned his head to look at the living room, "This is the first crime scene."

"We will do another more in-depth investigation." Diane replied quickly.

Jiayi, who was standing in the bedroom, raised her eyes and saw a young chemist pinching out a hair from the gap in the bed. The color revealed after being illuminated was dark brown.

That should be the thread-like thing deliberately left by the murderer. It turned out to be hair.

This behavior... Why does it look so much like what a person would do when he wants to frame another person after killing someone?

The torn photos found by the Forensic Department in the trash can in the living room were photos of the victim and a female friend with long brown hair.

"So, is it that the hair of the person in the photo fell here, and he tore up the photo to vent his anger?" Liu Jiaming stared at his forensic colleagues picking up photo fragments from the trash can while doing a preliminary scene piecemeal, staring at the portrait in the photo, and speculated.

"Stabbing the chest after killing someone is also to vent anger, this should be consistent. That means it was an acquaintance who committed the crime." Uncle Jiu also came over to look at the woman in the photo, "This woman with long brown-red hair is most likely the murderer."

Jiayi frowned and didn't say anything.

She turned around and suddenly stood in the living room corridor to observe the situation, then squatted down and looked under the sofa, and indeed saw a little cold light.

"Sister Diane, there's something here."

Diane immediately came over, leaned over to take a look, and took out the small thing that had not slipped far under the sofa with a pair of tweezers.

"It's an earring." Diane took a look before putting it into the evidence belt.

"Eh? It's the same as the one the brown-red-haired woman in the photo wore when she took the photo." Liu Jiaming found the latest evidence that 'the brown-red-haired woman is the murderer'!

Jiayi frowned and took a breath, something was wrong.

She actually had a feeling that the murderer seemed to know that she would see all of this, as if the murderer was guiding everyone to discover these evidences, and then let the entire B team point the finger at the brown-red-haired woman.

Recalling the flow image, the murderer occasionally stood in the dark and suddenly looked towards Jiayi's perspective, and Jiayi felt very uncomfortable.

Although her mind told her that the murderer had no way of knowing her existence, she still felt her hair stand on end.

…

The Forensic Department conducted two rounds of investigations at the scene. After the forensic officer, Sir Xu, completed the initial on-site examination of the body, he took the body back to the police station.

The detectives from the serious crime team did not all follow the car back, but scattered to collect evidence everywhere.

Liu Jiaming returned to the police station to investigate the identity of the deceased.

Fu and Gary continued to visit the area near the crime scene, looking for clues left by the murderer that night or the deceased's daily life.

The body was discovered by the nightclub's female manager Sister Yun, who provided the deceased's work information. Fang Zhenyue took Sister Yun and Liu Jiaming straight to the Daliyuan Nightclub on Portland Street.

After Ka-yee and Uncle Ko waited for Liu Ka-ming to get the family information of the deceased, they got into Uncle Kou's car and headed straight to the boathouse area in Nam Wan, Lai Chi Kok.

The roads in this area were muddy, with weeds all over the place. The boathouses were built on the shore, mostly inhabited by fishermen. The

person who answered the door was a middle-aged woman with chapped skin but delicate features.

"Excuse me, is Zhao Meini your daughter?" Jiayi asked politely, holding her ID and a photo of the deceased.

The woman did not look at the photo, but only glanced at Jiayi and Uncle Jiu who was standing behind with a cigarette, and said, "We don't have such a daughter."

Then she slammed the door shut.

Jiayi was turned away, turned her head and looked at Uncle Jiu, pursed her lips, and continued to knock on the door.

After dozens of seconds, the door opened again. It was still the woman, but her expression seemed more impatient.

"Miss Zhao Meini was found dead at her residence on Portland Street. May I ask if you are her mother, Li Xiaoqin?" Jiayi asked relentlessly.

After hearing what Jiayi said, the woman's impatient expression finally cracked. Her eyes flickered and she looked at the photo in Jiayi's hand. Her lips trembled slightly, and after a few breaths, she pursed her lips again, suppressed all her emotions, and said coldly:

"It doesn't matter if she dies. It's better for someone who disgraces the family to die."

"..." Jiayi opened her lips in disbelief.

The woman raised her eyes to look at her, muttered something, and closed the door again.

Jiayi looked down at the photo in her hand. The living Zhao Meini had delicate features and was a pretty girl.

If you look closely, you can actually see that she is somewhat similar to the tanned woman who opened the door just now. They both have big eyes and naturally long thin eyebrows, but one has tanned skin, looks old and dull, while the other is well-maintained and fair-skinned, youthful and bright.

I realized that it was probably because Zhao Meini had gone astray that her family no longer recognized her.

But no matter what, she is their daughter. Wouldn't they be sad if she died outside? Wouldn't they hope to help their daughter catch the murderer?

Uncle Jiu sighed and gently pulled the female police officer.

"Forget it. Parents are just blood relatives. If there is no emotional accumulation, it is normal for the emotions to be indifferent. If parents think they have invested a lot of effort in their daughters, but the daughters do not grow up according to their plans and expectations, or even become unfilial and unfraternal, they may become enemies." Uncle Jiu took a puff of cigarette, turned around and walked along the short wooden bridge leading to the boathouse onto the sandy road, leaving behind a somewhat bleak back.

Jiayi pursed her lips, turned back and stared at the wooden door, and then caught up with Uncle Jiu.

"Let's go ask the neighbors." Jiayi caught up with Uncle Jiu.

"Okay." Uncle Jiu threw the cigarette butt on the ground and crushed it.

...

...

The most densely populated community can also be the most indifferent community.

The most prosperous city can also be the most impetuous city.

On the way back, whenever the car in front was a little slower, there would be a car behind that would slam the steering wheel.

On the way, people lose their self-cultivation. Even if you were an educated person or a lady, you will forget it in an instant. All you can do is hurry up and snap.

Jiayi sat in the passenger seat, watching the hazy black clouds gradually fade away in the sky. Suddenly, her mind extracted information based on the flow image, and suddenly recalled the faces of everyone she saw in the process of interviewing citizens to collect evidence today, their expressions, tone, attitude...

Because they had the longest journey and it took the most time to ask the neighbors

one by one, they became the last group to return. When they returned to the office of Group B, everyone was waiting for them. They sat and chatted while eating the afternoon tea that Sun Xin brought half an hour ago.

"Houses in Hong Kong are getting more and more expensive now, which is really unfriendly to citizens. We are considered high-paying jobs, but we may not be able to buy a house even if we spend all our savings. Ordinary citizens may never have their own house." Fu sat on the chair and shook his head to complain. "

A house of 1,000 square feet costs 4 million in full! How long will I last... It's better to let me get seriously injured in this case and use a few years of salary as financial compensation, then maybe I can afford a house." Gary said heartlessly.

Uncle Jiu, who had just stepped in, was instantly furious and slapped Gary, "Bah! Nonsense! Come over and burn incense and worship." Uncle

Jiu, who was still covered with the damp air brought in from outside, grabbed Gary and dragged him to the statue of Guan Gong, and forced him to burn a stick of incense devoutly.

After worshipping, Gary stuck the incense into the incense burner, turned around and stuck out his tongue at everyone, chuckling.

Jiayi didn't bother to talk to others, and first picked up a cup of hot raw coconut milk coffee, which was slightly sweet and bitter with the aroma of coconut milk. The hot liquid rolled into her esophagus and warmed her whole body.

The aftertaste of fresh milk filled her mouth, and her body and mind were healed. She let out a long breath.

It's so cold outside, and it's so warm in the house.

"Eleven, do you want to move to a new house too?" Liu Jiaming leaned over to look at Jiayi.

"Yes, but I went to see a house with my eldest brother. It's not too expensive, but the size and quality are similar. There's no need to move. Let's save some money." Jiayi said helplessly. Economy, money, money, annoying things that can't be avoided.

"We'll help you check it out later and recommend you a suitable house." Uncle Jiu also picked up a cup of hot drink.

"We'll help you check it out." Fang Zhenyue and Qiu Sushan came back from the Forensic Department and the Forensic Management Department respectively, and they also spoke after entering the office.

"I have a friend who is going to immigrate to the UK, and her house in Mong Kok is vacant. I'll ask her if she wants to rent it later." Qiu Sushan found a chair and sat down.

"Okay, okay, thank you everyone." Jiayi's heart warmed up a little more.

"Come on, let's have a meeting. Everyone talk about the information they have collected." Fang Zhenyue uncapped the marker, wiped off the messy graffiti on the whiteboard, and said seriously.

"The first report from the medical examiner showed no injuries caused by sexual assault. The private parts examination concluded that the deceased had had sex multiple times before death, and the preliminary judgment was that there was no direct connection with her death. There were no other suspicious wounds on the deceased's body. Extracts from nails and other parts have been sent for testing, and the results will probably be available tomorrow or the day after tomorrow. The fatal wound to the deceased was a blunt force wound to the back of the head, not a sharp force wound to the chest." Madam, who received the report, was the first

to be shocked: "In other words, the murderer did not need to stab the deceased in the chest, so it is speculated that the murderer was just venting his anger. This can prove the conclusion that the crime was committed by an acquaintance."

"It could also be a sense of ritual." Uncle Jiu recalled the scene of the corpse lying in the bedroom, the naked corpse, lying in a standard sleeping position, pale skin and a red blood hole on the chest, and the clothes neatly stacked on the side... No matter how he thought about it, he felt eerie.

"Or maybe he had planned in advance to use the fruit knife in the deceased's kitchen, but he didn't expect that a blunt weapon hitting the head could kill the deceased. So the murderer still followed every step he had planned in advance and executed it step by step." Jiayi said sullenly.

"You mean like Ye Yongqian in the Baojin robbery, who planned all the details such as time and process clearly before setting out, and then carried out the murder exactly according to this plan?" Gary couldn't help swallowing. Are all people nowadays devils?

"It's all the newspapers' fault for over-reporting and not knowing how to hide the details of the murderer's crime and the police's solving of the case. The Public Relations Department still has to continue to define the boundaries of their work!" Uncle Jiu complained angrily.

Fang Zhenyue nodded and wrote down a few words on the whiteboard: [Acquaintance, high IQ murderer]

Then, he shook out the first batch of reports he got from the Forensic Department, took over from Madam and said:

"The shape of the crystal ball and the bloodstains basically match the blunt force wound on the back of the deceased's head. It can be determined that this crystal ball is one of the murder weapons. It was placed on a small shelf at the door. There are 3 photos in the victim's album with the wall with the shelf as the background, which can prove that the murder weapon was originally here."

As he said, Fang Zhenyue took out a photo and pasted it on the whiteboard.

"The murderer either knew the layout of the victim's home very well, or he just had an idea on purpose and happened to see the murder weapon nearby," Fu analyzed.

"The night before, the community where the victim lived had been without electricity. The murderer was killing people and folding clothes in the dark. It must be someone he knew who committed the crime," Liu Jiaming said. He wanted to think that it must be the woman with long brown hair, but seeing everyone's serious expressions, he did not make such a conclusion rashly.

"But why did she take off the victim's clothes and then fold them again?" Fu asked.

"Maybe it was a kind of revenge, such as disgust for the victim's career? Or... some kind of neatness?" Liu Jiaming was also confused.

"Do you think that people who came naked should also leave naked? Only in this way can they be neat and tidy? Is it a neat ritual?" Uncle Jiu frowned and analyzed.

"Well... let's not speculate too much, let's sort out the clues.

"No blood of a second person was found in the victim's home, and no suspicious fingerprints were found in the search for the route of death. But long brown-red hair and an earring were found, and these clues should point to the murderer."

Fang Zhenyue said and posted 5 more photos on the whiteboard, one was a photo of the long brown-red hair, one was a photo of the earring, one was a torn photo restored by the Forensic Department, one was a photo of the perfume thrown in the trash can, and another was a photo of the neat clothes folded next to the body:

"Another abnormality found is this torn group photo. And there's this bottle of perfume, which is not cheap, that was discarded even though it was not used up. And finally, there are the neatly stacked clothes beside the bed."

Jiayi stared at the photo of the perfume, and it matched the image of the small bottle that the murderer threw into the bathroom trash can in the final scene of the mind flow image.

"Next, we need to find the suspect so that we can compare it with the things left at the crime scene." Fu continued.

"Yes. "Fang Zhenyue nodded.

Jiayi pursed her lips. No one could see that the murderer had taken out these things on purpose and made these arrangements.

Just as the murderer had arranged, they were led step by step by the nose to the path paved by the murderer.

Jiayi was a little uneasy. Countless words came to her lips, but she suppressed them.

"Gary and I visited the neighbors around the victim's residence. The deceased often brought different men home. They should be the perverts she met in the nightclub.

"Some neighbors also saw her bringing female friends to visit. The neighbors only remembered one, the woman in this photo." Gary circled the woman's face and handed it to Fang Zhenyue.

"We have confirmed this woman in the nightclub. Her name is Clara. She is a hostess with a bad temper." Liu Jiaming also handed out a photo. It was a group photo of 6 women with his names written on it.

Everyone looked at the photo of Clara. She had a beautiful face, upturned eyes, and high eyebrows. It was obvious at a glance that she was mean and irritable and difficult to get along with.

The key point was her long brown hair!

"Ah, that torn photo was a photo of the victim and Clara." Gary shouted

with his eyes wide open. "Clara!" Fu clapped his fists.

"Clara..." Uncle Jiu also read out her name.

Everyone seemed to have felt that the murderer had become clear.

Jiayi's eyes swept over everyone in the photo, not looking at their appearance, but only at their figures.

Most of them were about the same height as the deceased, only Clara, Sister Yun and the tallest black-haired woman standing at the edge were much taller than the deceased.

The photo was taken in autumn, and everyone was wearing thick clothes, so it was hard to tell whether they had muscles.

Jiayi was not sure whether Clara, Sister Yun and the other tall woman were the murderers, and only remembered their names.

Clara was a person with a bad temper and had conflicts with the deceased.

But she had been like this for a long time, would she suddenly kill someone because of an argument?

What was so special about the customer that Clara believed the deceased was competing with her for?

Sister Yun was the manager on duty at the nightclub, and she was the one who found the body. Could it be her?

The other tall black-haired woman standing at the edge was called Qin Hongliang.

She has sparse eyebrows and eyes, and her facial features are not very delicate. Only her height and long legs are noteworthy. Among this group of pretty girls, she is not eye-catching.

Jiayi knows nothing about this person. She has to see her in person, look at her muscles, and listen to her voice before she can make a rough judgment.

This photo was posted on the board by Fang Zhenyue. Fu continued:

"Because the deceased often hides during the day and goes out at night, the neighbors rarely run into her. Occasionally, she is seen taking out the garbage, and she doesn't talk much. She has never seen any relatives, old or young, visit her, and she doesn't have a regular boyfriend. The people around her are very messy, and it is difficult to tell whether she has any special social circle."

Jiayi shook her head. The murderer is not a man, and he can't be the boyfriend of the deceased.

"The housekeeper downstairs went to sleep in the small mailroom next to the first floor after 1 a.m. every day. He would not get up until about 6 a.m. the next day. He only saw the deceased go out, but did not see when the deceased returned home, or whether he brought anyone home with him." Fu continued.

The murderer completely avoided all witnesses when committing the crime. Did she know the biological clock of the housekeeper downstairs?

"The deceased did not receive any special visits or behave in any special way on the day of his death or the day before. Neighbors did not see anything special on their way to work in the morning. Only the neighbor said that he heard noises at night, but he was not sure. Also, there was no garbage at the door of the deceased's house as usual in the morning." Fu stared at the group photo on the whiteboard, pointed at the middle-aged woman, Sister Yun, who was still charming in the middle, and said,

"The deceased made an appointment with Sister Yun, the nightclub manager, this morning, to go and look at the shop together. Sister Yun kept knocking on the door and no one answered the phone, so she used the spare key given to her by the deceased to open the door and found the body."

"The body was found so quickly, so we were very prepared to determine the time of death." Qiu Sushan glanced at the report from the forensic department, "It was just after five o'clock this morning."

"It was discovered so quickly, the murderer didn't expect it." Liu Jiaming sighed.

"Maybe everything is in the murderer's plan." Jiayi looked at the words "High IQ Murderer" on the whiteboard.

"Ah, why do you do this?" Liu Jiaming didn't understand for a moment.

Jiayi glanced at Liu Jiaming, who looked confused.

Then she turned her head to look at Fang Zhenyue, who had a clear expression and obviously understood what she meant.

Since the murderer has so many plans, then Clara, the brown-haired girl who is the most suspected at the time of the victim's death, must have no alibi.

The murderer probably knew that Sister Yun would go to see the victim this morning, so he arranged to strike at this early morning.

He wanted her to find out and call the police, and then the police would infer the time of the victim's death.

Brown-red hair, an earring, torn photos... and this time of death, one after another.

Jiayi's scalp tingled slightly, and a sense of vigilance and fear arose from the bottom of her heart.

The murderer has a strong anti-detection awareness. Before committing the crime, he probably had rehearsed countless dealings and games with detectives in his mind.

Jiayi didn't like the feeling of being led by the nose. A fighting spirit gradually emerged in her chest. She stared at the photo of Qin Hongliang on the whiteboard and pursed her lips lightly.

Liu Jiaming, who was sitting next to him, sensed the vague murderous aura and turned to look at Yi Jiayi's profile. He saw that she frowned and narrowed her eyes, emitting cold lightning.

He shuddered unconsciously.

Wow, Xiaoyi looks so fierce with her short hair.
