Chapter 380: Playing tricks and scientific investigations [2 in 1]

"…some law-abiding citizens who usually do not show violent behavior may commit violent acts under certain circumstances, and may even be as barbaric and cruel as primitive people.

"This group can be a group of students on campus, a group of colleagues in the workplace, a group of people who watch movies together, a group who play the same game together, and even neighbors in a community.

"For example, when a person has moral flaws, or someone makes him or her appear to have moral flaws through rumors, other people in the group get a get-out-of-jail card to use violence against this person at will. The group is encouraged to commit the worst acts, still believing that they are acting in justice and doing the right thing. In such a group, people who do not use violence will be excluded, and therefore tend to be like sheep in a flock, even if the lead sheep is heading towards a cliff, they will follow blindly.

"Therefore, the law must be absolutely fair, absolutely rational, based on solid evidence, and cannot be incited.

"So, for all acts of group violence, we cannot infer whether an individual in the group has a tendency to commit evil based on whether he or she was a law-abiding person.

"When doing this kind of profiling, we must place these individuals who may have been good people in the group as a whole for consideration.

"This is also why when investigating group violence, we do not exclude people with no criminal record as suspects..."

Jiayi stood in front of the conference room, speaking and writing at the whiteboard.

She is now completely different from the first time she went on stage to explain a word document. She no longer needs to regard the people in the audience as tables and chairs, and she no longer feels nervous and afraid because of speaking in front of people.

Deliberate training and the accumulation of a lot of experience will make people numb, habitual and brave.

The people sitting in the audience were all detectives or uniformed police officers from various police stations in the Central District, and some inspectors and sergeants also came to listen to her sharing. Jiayi spoke very seriously, breaking down some boring and difficult knowledge points into cases she had experienced or read to explain to everyone.

In the second half of the course, a male detective suddenly appeared at the door of the conference room. Because he came too late, he had no seat and could only stand in the last row with his arms crossed.

Compared with other detectives who came to listen to the sharing class, he seemed too sloppy and messy, with a little oily hair. Although it can be seen that it has been combed, it is still a little disobedient and messy. His complexion was not very good, dull and oily, with dark circles under his eyes, as if he had just survived several nights of sleep, not to mention the wrinkled white shirt and trousers on his body.

Jiayi stared at him for a few seconds and recognized that this man was the inspector Dylan (迪伦) of the Central District Serious Crime Unit C who had been photographed during the recent news broadcast of "The Ghost Calls Again".

After the analysis was completed, many people would come over to shake hands with Jiayi to express their gratitude, or chat for a few words about what she mentioned.

Dylan hesitated at the door for a while, and also came over to shake hands with Jiayi.

When he was about to leave after expressing his approval of Jiayi's speech, Jiayi took the initiative to mention the case he was investigating:

"Dylan, after interrogating William who pretended to be a ghost and made a phone call and collected a statement, it cannot be determined that it was a false report or obstruction of justice because it was just a report for the deceased. In addition, there is indeed suspicion of homicide in the case. William's phone calls to harass the public can only be warned. In order to prevent public opinion from completely turning against the police, William was released from the police station this morning, right?"

Dylan nodded and sighed, "That's right, the case needs to be re-examined, and William's reporting the case is actually a heroic act."

"Many media will scramble to interview William. This matter will only get bigger and bigger. It will not be calmed down just because the "Ghost Calls" is exposed." Jiayi stated with a stern face.

She has been dealing with the media for too long with Mr. Guo, and she has foreseen this situation.

"Mr. Guo also told me so, but there is nothing I can do. I can only continue the investigation. The rest..." Dylan pinched his eyebrows in annoyance.

Jiayi looked at him silently, thinking about how to start the conversation next, but Dylan actually looked up at Jiayi and asked hesitantly:

"I wonder... Madam Yi, are you free and willing to help take a look at this case from the perspective of criminal psychology and profiling, which are your specialties?"

Dylan stopped talking, but then worried that he was asking too much. After all, this matter had nothing to do with West Kowloon where Yi Jiayi was, and it was inappropriate for him to drag her into his mess.

But unexpectedly, Yi Jiayi didn't even hesitate, and nodded directly:

"OK."

Dylan looked up in surprise, and then wiped off his tiredness, and said in surprise: "Thank you, thank you madam!"

...

Although Jiayi can only stay in the Central Police Station to help Dylan today, Dylan is already very happy.

Most of the Hong Kong police force in the 1990s were police officers who came out of the old-school education. Criminal psychology, profiling, and solving cases by DNA are all very new to the old police.

At first, everyone was a little bit indifferent and rejected these new things, but with people like Yi Jiayi actively accepting new technologies and new methods, and even solving strange and major cases by using them, the attitudes of the detectives changed from questioning to admiration.

Dylan had long coveted Yi Jiayi's skills and talents, and finally had the opportunity to see them in person. Especially when the case he was investigating was in a difficult period, he needed Yi Jiayi even more.

Dylan took Jiayi to the Central District Serious Crime Unit C office while briefly introducing the current status of the case to her. Jiayi

listened attentively, and took the next step into the office without any preparation. A sour smell hit her face. She looked up in shock and was almost suffocated.

There is a rest room in the police station where you can take a shower, and the police force also has a service to help with laundry. These detectives can make themselves so smelly. It seems that they are really tortured by this case. They probably have been in the office all night for more than one night.

The detectives were gathered together to discuss details and clues. After Dylan reminded them, everyone noticed that someone had walked in.

The detectives came back to their senses and stared at Yi Jiayi for a while before they realized who this person was. Then they stood up one by one and saluted Yi Jiayi and said hello:

"Madam Yi!"

"Hello everyone." Jiayi smiled and nodded.

"Madam Yi came here as an expert to help us sort out the clues. Today we will reorganize the case from the beginning." Dylan clapped his hands and introduced to everyone.

"Really?"

"That's great~"

"Thank you, Madam Yi~"

"Wow!"

Everyone had heard of Yi Jiayi's name. It was said that since Yi Jiayi came to the West Kowloon Serious Crime Unit B, they had never worked overtime for consecutive nights.

The detectives, who were tortured by the cases, ignited hope and their eyes lit up: once Madam Yi came, would everyone be able to close the case and go home to rest?

"From now on, everyone will listen to Madam Yi's orders, and so will I." Dylan patted his chest, turned around and asked Yi Jiayi with special sincerity:

"Follow your rhythm and habits, please give me your instructions."

Jiayi hesitated for a few breaths. Since Dylan said so, she was not polite.

So she walked to the table, looked around, and said without any doubt:

"Go home, wash up, change clothes, and have a good sleep."

She glanced at her watch, and then said:

"It's 11 a.m., everyone will gather back at 4 p.m."

"..."

"?"

The agents were gearing up and waiting for Yi Jiayi to order them to spin like tops. They never expected that the order they received was to go home and sleep.

"Next, I need to look at the files and think about the case. I will go to the forensic department to see the corpse and the forensic department to understand the test logic. This all takes time." Jiayi clapped her hands and said, "You have wasted 5 minutes of rest time. Come on, let's go."

The agents looked at Yi Jiayi and then at Dylan. When Dylan nodded after regaining consciousness, everyone stood at attention and saluted, picked up their coats, and ran out.

When they left the office, their pace was quite normal, but once they turned into the corridor, they all started to jog - they were obviously eager to go home, take a good shower, and have a good sleep in the soft quilt.

Jiayi couldn't help laughing when she heard the footsteps running in the corridor. She turned around and said to Dylan:

"I would like to trouble Dylan-sir to stay and accompany me to look at the documents. Take me to the Forensic Department and the Medical Examiner Department later."

"Of course." Dylan nodded and went to buy coffee, ready to have a brainstorm with Yi Jiayi, but he didn't expect to hear her say:

"However, Dylan-sir, please go to the police station's locker room and take a shower, relax and take a rest. I'll be looking at documents in the office. If I need to talk to you, I'll call you."

A few minutes later, Dylan was also driven out of the office by Jiayi. He opened the window to get some fresh air by himself. At the same time, he called the administrative department of the Central Police Station to contact the cleaning lady to come and clean the office, and bought a bunch of fragrant flowers to put in the office.

...

In the next few hours, the media followed Wiliiam for interviews and broadcasts as Jiayi expected.

Wiliiam was encouraged and talked about his logical reasoning on TV, concluding that the murderer was the deceased's current boyfriend Liang Xinwen. He insisted that it was Liang Xinwen who snatched his girlfriend Wang Mou'e from him, and finally did not know how to cherish her and killed her. He was a very bad man and extremely evil.

In the interview, he loudly called on the police to catch the murderer as soon as possible and give his ex-girlfriend the truth.

Some people who watched TV originally sneered at the ghost calls for help, just watching it for fun, but now the nature of the case has really changed because of Wiliiam's phone call, and these citizens have begun to doubt Wiliiam's statement.

Some people even began to spontaneously go to Liang Xinwen's small company based on Wiliiam's fingerprints to hold up signs to protest, demanding that Liang Xinwen plead guilty.

Wiliiam had been on TV for just over two hours when the situation moved forward rapidly.

Liang Xinwen also appeared on another talk show wearing a mask. He claimed that Wiliiam, who made the call, was a lunatic. He pointed out that this person was the murderer today, and he might point out that another person was the murderer tomorrow. His evil behavior of seriously damaging the reputation of citizens and spreading rumors has a huge negative impact on the lives of citizens. He must stop it.

He scolded Wiliiam for an entire talk show, and even repeatedly exposed the weird things about Wiliiam that his deceased girlfriend Wang Mou'e had complained to him about.

At the end of the show, Liang Xinwen shouted at the police indignantly:

"Is this how the police handle cases? Believe in ghosts and gods, and be controlled by madmen? I am innocent! The police must clear my name, and William must apologize to me and compensate me for the mental damages for privately exposing my information on the show..."

The situation is still fermenting, and the continuous emergence of new materials has led to a traffic frenzy for the media.

…

…

At 4 pm, when the detectives of the Central District Serious Crime Unit C returned to the office, they almost thought they had walked into the wrong room. They

left and looked at the door number before they dared to really walk in.

The office was brand new, the floor was clean, the takeaway garbage piled on the table was gone, and the sour smell in the room was gone, replaced by the fresh floral scent.

On the desk was afternoon tea with the Yi Ji logo. Madam Yi, with sharp eyes, stood by the whiteboard with her arms folded, inviting everyone to drink Yi Ji milk tea while asking everyone to take a seat and prepare for the meeting.

The detectives were about to shed tears. Could the environment of being a detective be so good?

The detectives who used to be straightforward and rough suddenly felt a little embarrassed. They all became polite and kept saying thank you.

After everyone sat down, they noticed the neat handwriting on the whiteboard:

1. [Relationship with lovers]:

Suspect A: Liang Xinwen, the current boyfriend of the deceased, a small businessman;

Suspect B: Tim, the deceased’s ex-boyfriend, a bartender;

Wiliiam (a securities company employee) who pretended to be a ghost

and called was actually the deceased’s ex-ex-boyfriend. After the deceased broke up with Wiliiam in May, she started dating Suspect B, and according to B, they broke up at the end of August.

Suspect A said that he and the deceased started dating in early September and have been in love ever since.

2. [Relationship with colleagues]:

Suspect C: Real estate sales, a competitive relationship with the deceased;

3. [Existing clues from the Forensic Department]:

…

4. [Existing clues from the Forensic Department]:

…

…

Apparently, during the few hours the detectives were resting, Yi Jiayi had read and sorted out all the confessions and clues they had collected in the past few days.

However, if that was all, it would probably be impossible to find a breakthrough immediately. No

matter how suspicious Liang Xinwen was, no matter how much he lied in his confession, the crime scene was severely damaged after all, and no fingerprints or footprints of Liang Xinwen were found. No other evidence that he was the murderer was found later, and the police still could not catch the murderer and solve the case.

No matter how many times the existing content is sorted out, it is just a matter of changing the words and sentences but the same meaning and filtering them again. What's the use?

After reading the words on the whiteboard, everyone took a sip of iced popsicles, and looked at Yi Jiayi with uneasy eyes.

Jiayi, who was standing next to the whiteboard, was very calm. She waited patiently until everyone was seated before she spoke:

"First, let's take a look at suspect A Liang Xinwen. The reason why everyone set him as suspect No. 1 is because Wiliiam, who pretended to be a ghost and called, believed that he was the murderer. Although we reopened the case based on Wiliiam's phone call and indeed discovered that it was not suicide but homicide, we cannot be too influenced by him.

"So I hope everyone forgets about Wiliiam, and we put the importance of the clues on the same line again and reconsider it. "

Jia Yi said, and drew a line under the names of other suspects.

Just as everyone was digesting her words, Jia Yi snapped the pen cap shut, turned around and said calmly:

"I have obtained the deceased's phone records from September to before his death. Since all suspects must be thoroughly checked, Ah Wei, you should also retrieve the deceased's address book from July and August. Bring it to the office tonight, ok?"

Ah Wei was stunned for a moment, then stood up and said, "Yes, madam." After that, he turned around and nodded to Inspector Dylan, then strode out of the office to execute.

Seeing Ah Wei leaving, Jia Yi turned to another detective and said,

"Brother Daxing, go and check the deceased's financial transactions and income and expenditure for the past four months. "

Yes, madam." Daxing followed Ah Wei's example, stood up, answered and left.

In the corridor, he caught up with Ah Wei and said excitedly: "Madam Yi knows my name, and calls me 'Brother Daxing'~" He

looked particularly honored and happy.

When the conversation was reported back to the office, Jiayi pursed her lips and smiled, then continued seriously:

"Xiaobai, go check the financial status of suspect B, the deceased's bartender ex-boyfriend Tim. Sister Bella, go check the financial status of suspect C."

Because Liang Xinwen's financial status has been checked, this part can be omitted.

"Sun Shazhan, please visit the deceased's neighbors and screen again all the people who have been to her home within two weeks before her death. After that, we will also visit the neighborhoods of suspect A and suspect B to understand their whereabouts and conditions before the death of the deceased."

Jiayi acted quickly and quickly sent out all the people under Dylan's command.

Dylan wrote down Yi Jiayi's arrangements in a notebook, raised his head and looked directly at Yi Jiayi, "Madam, what do you need me to do?"

"Dylan-sir, apply for a search warrant. I want to go to the home of the deceased Wang Min'e with the Forensic Department."

Jiayi had already seen Rick, who was in charge of this case in the Forensic Department, and Wang Min'e's body in the afternoon.

In the mind flow image, she saw the murderer -

[The man had been waiting on the rooftop for a long time. When he saw the deceased Wang Min'e rushing over

angrily, he knelt down in front of the deceased, holding the deceased's hand, begging to reconcile with the deceased and begging the deceased to lend him some more money... Wang Min'e sneered in anger, slapped the murderer twice, and threatened that if the murderer did not pay back the money, she would go to the bar where he was and make a scene until everyone knew that he was a gambler. , and he didn't pay back the money he owed his ex-girlfriend.

The murderer cried and climbed up, threatening to die, and then he denounced Wang Min'e for not caring about their old relationship, and he also shouted that if she continued to force him, he would jump down and die.

As Liang Xinwen said, Wang Min'e had a very hot temper. She watched the murderer threatening to die and crying for mercy, and not only did she not be fooled, but she scolded him for being spineless and a rotten person, and ordered He returned the money as quickly as possible and turned to leave.

The murderer got angry and rushed over to pull her, and the quarrel between the two escalated. After a few struggles, the murderer suddenly showed a ferocious look and pushed Wang Min'e hard.

Wang Min'e, who was standing closer to the edge of the roof at the time, fell down, but grabbed the railing with her backhand and had a chance to be rescued.

The murderer was originally overwhelmed by his own behavior and Wang Min'e's crisis. The murderer was frightened by the situation, but after staring at Wang Min'e who was shouting for help for a few seconds, his face suddenly turned cold. Not only did he not help, but he kicked Wang Min'e's head and face violently, eventually causing Wang Min'e to let go and fall downstairs.

The murderer was not Liang Xinwen, but another suspect B - the ex-boyfriend who actually snatched Wang Min'e from Wiliiam, the bartender Tim.

Dylan heard Jiayi's request and thought that since he had already asked her for help, he might as well follow her all the way and give it a try.

Anyway, they were already in trouble, so they might as well trust her completely, listen to her arrangements, and investigate for three days before making any decisions.

"OK, madam." Dylan responded and returned to his office to make a phone call to apply.

In the blink of an eye, Jiayi was the only one left in the Central District Serious Crime Unit C office.

She took a deep breath, turned her head to face the whiteboard, stared at the photo of Tim pinned on the whiteboard, and murmured in a low voice:

"The bullet fired when you were young will hit your forehead decades later. No one can escape the consequences of doing something wrong."

Do you think you can frame others and completely escape punishment?

There is no such a good thing.
