Criminal Investigation Notes

When we were in school, Weng Yuhua was very kind to Su Hui.

A few years ago, there was no special department of criminal psychology in China, and the course of criminal psychology was only set up as an auxiliary course of the crime academy.Weng Yuhua teaches the course of criminal psychology. He has a good understanding of the relevant history at home and abroad, and he also has many unique insights in the academic field.

During college, Weng Yuhua has always taken good care of Su Hui, and also has the intention of cultivating him.

He led Su Hui to publish his first paper in a core journal, introducing him into the relevant academic circle.

Later, Su Hui naturally chose to be a graduate student of Weng Yuhua.He completed his postgraduate studies two years ahead of schedule. When he was about to graduate, Mr. Weng asked Su Hui if he would like to stay in the school to teach.

At that time, Su Hui yearned to apply what he had learned, and wanted to go to the front line. Teacher Weng did not stop him, and supported his choice of entering the police station.

When Su Hui was about to graduate, several places extended olive branches to him, and some of them offered higher salaries than Huadu. After Su Hui and Yu Yan met twice, they finally chose to work in Huadu.

When teachers and students say goodbye, years have passed.

Now that we meet again, it has been a long time, and things have changed.

In the past few years, Su Hui has also heard some news about Mr. Weng.

Teacher Weng's wife passed away three years ago.

Since Weng Yuhua suffered a stroke half a year ago, his legs and feet have not been very flexible. Since then, he has been relying on a wheelchair to travel to important events. Weng Yuhua's junior, Sui Liangyi, has taken good care of him and has been by his side all the time.The two are not only brothers and sisters, partners in work, but also friends in life. They have helped each other all the way until now.

"Teacher Su is also here for the rehearsal?" Seeing Su Hui, Sui Liangyi smiled, bowed his head and said to Weng Yuhua, "Look, the two of us have worked hard all our lives, and in the end it's you, the apprentice, who strives for success. Criminal psychology and criminal investigation practice Combined, he has repeatedly solved major and important cases, and he can even get rewards that we didn't even dare to think about back then."

Su Hui could tell that Sui Liangyi had some complaints about the results of this award.

He won the award that seniors like them hadn't won yet.

Weng Yuhua didn't look too good, and he was a little tired. He said, "The waves behind the Yangtze River drive the waves ahead. This has been the truth since ancient times. Su Hui has always been my proud disciple."

Then he turned his head to look at Su Hui, as if explaining for Sui Liangyi: "Su Hui, you have done those things, solved so many cases, and endured a lot of hardships, so you should be rewarded like this. Your uncle is doing it for you." you are happy."

"Thank you, Professor Sui, thank you Teacher Weng." Su Hui said as he took out a small box, "Mr. Weng, I didn't have time to attend your 60th birthday this year, so I bought a small gift for you. I will wait for the award presentation in the afternoon." After the ceremony, I would like to invite you to have a meal together."

Sui Liangyi took the initiative to help take the small box and put it in Weng Yuhua's hands.

Weng Yuhua opened it and found that it was a small and exquisite tie clip. It could be seen that it was a gold ornament and the material was very good.

His heart skipped a beat, and he reached out to take out the tie clip and put it on the tie.

Weng Yuhua raised his head and said back to Su: "I accept the gift, thank you. But we have to rush back today, so we won't have dinner with you. Let's wait for the next opportunity."

It seemed that they were going to leave after they had finished their session.

Su Hui didn't force it, chatted with them a few more words, turned and left.

Sui Liangyi pushed Weng Yuhua and walked through the venue. Since the ceremony hadn't officially started yet, many people were still chatting.

The host on the stage rehearsed the award speech: "With his superb criminal profiling skills, through meticulous reasoning and evidence collection, he has repeatedly solved major cases and brought criminals to justice, especially in this year's..."

Hearing this, a sneer appeared on the corner of Sui Liangyi's mouth: "Your good apprentice..."

Weng Yuhua lowered his head and whispered: "He is also doing his duty."

Not far away, Bureau Tan was also chatting with the leaders who were present, and someone asked him, "Boss Tan, are you still investigating that case?"

Director Tan sighed: "Speaking of this case, fortunately, Mr. Su is in our bureau. With his efforts, I believe we will be able to find out the truth soon and get to the bottom of it."

"Hey, Consultant Su is really excellent. But it has indeed been delayed for a while. Aren't you going to apply for expert assistance from the provincial department?"

Bureau Tan looked not far away, waved his hand and said: "Although the experts from the provincial department are very capable, they don't know the situation in Huadu after all. Let's do it ourselves. After so long, the detection work is still a bit difficult. Yes, the real culprit behind the scenes has not been found yet, but it is only a matter of time..."

Sui Liangyi pushed Weng Yuhua, passed by quietly, sat in the front row on the right, and began to greet other leaders present at the meeting.

Soon, the whole process went through, and when the hour came, the leaders took their seats and the meeting officially opened.

The meeting begins with a speech by the leader.

Afterwards, the leaders of each general bureau made a summary.

When it came to the awards ceremony, the winners came to the stage one by one.

After two hours, the meeting finally came to an end.

After Sui Liangyi finished winning the award, he pushed Weng Yuhua to greet the leaders in the front row, and then left.

In the back row, Su Hui and Lu Junchi looked at each other, and Lu Junchi also left the scene.

Su Hui's award was in the second half of the meeting, and there was a half-hour break in the meeting arrangement.

Sui Liangyi pushed Weng Yuhua out, handed him a cane to hold in his hand, he put the folding wheelchair in the trunk of the car, and took him to the outskirts of Huadu.

Weng Yuhua looked down at the tie clip Su Hui gave him on his tie.

Back then, his wife always reminded him to carry this little thing. According to her, the tie clip is the soul of the tie, and it looks good only when it is worn.

Once he forgot, Madam even took a taxi to the venue. Su Hui was there at that time, watching the couple straighten their ties.

In a flash, so many years have passed.

Now that his lover has passed away for three years, he still always forgets these details, but Su Hui still remembers them.

The car stopped suddenly.

Sui Liangyi got out of the car, opened the door, pulled Weng Yuhua out of the car, and helped him to the bench by the river.

Weng Yuhua frowned and looked up. This is a secluded riverside, which looks familiar.

Sui Liangyi said: "Brother, do you still know where this is?"

Weng Yuhua raised his head to identify it for a while, the surroundings had changed a lot, but he still recognized it, this is the old site of 372.

He adjusted his glasses: "I know. When we were young, we made decisions here."

For him, it was a bad memory.

Twenty years ago, the public security summary meeting of that year was also held in Huadu.

Weng Yuhua remembers that the reason why he wanted to build the 372 Institute of Psychology was because at that summary meeting, as a police consultant, he conducted a work summary and presentation in front of all the leaders.

At that time, he was impassioned, but the audience below was silent.

At the end, the leader gave him a light sentence: "Yuhua, your work is progressing very well, and I also support you to do these emerging theoretical research, but what you said is not supported by data and examples. There are no results that can be brought out. I hope that you can put everything into practice."

The people below talked a lot: "This set of methods is all foreign, and it will be unacceptable in China."

"The law and order in the country is very good. Serial killers are rare."

"The prevention plan he proposed will cost a lot of manpower and material resources, and it is not necessary at all."

"These theoretical studies are only on paper, and it is enough to give lectures in schools, and they cannot be applied to reality at all."

"Yeah, so his consultant is only in name, and the police below are not willing to cooperate at all."

"It's very lively, but it's not practical. Those old detectives in our bureau are much better at solving cases than these."

Weng Yuhua's face became paler and paler as he listened.

His heart was beating fast, like thunder, and he wanted to refute these people's words loudly, but he stood awkwardly in front of the stage, unable to say anything.That sentence, like an ice blade flying over, extinguished all the light in his heart, and he felt the blood in his body gradually cooling down.

He used to study relevant theories so desperately, translate relevant documents, and popularize the most basic knowledge in various conferences.

He started from scratch and was one of the first researchers to study criminal psychology. He seemed to be facing a wilderness, carrying a heavy responsibility, and striding forward with difficulty.

He once imagined that everything would blossom and bear fruit, and the profiling technique would be applied to every case and play a huge role.

But everyone looked at him with puzzled and repelled eyes, as if they were listening to the Arabian Nights.

Is this a waste of time?

Is it meaningless?

Do we really not need to conduct relevant research?

He has taught so many talented students, but they can only change jobs, or go abroad for further study, and cannot find jobs in China at all.

He wanted to advise the police officers, but no one was willing to listen to his analysis.

Weng Yuhua was confused.

Want to give up?

Or should I ignore all this and be a good man who only says the right thing?

He is not reconciled, this is his interest, it is the career he was prepared to devote his whole life to...

He is already in his forties, how far can he go on this road?

Weng Yuhua took a deep breath.

At that time, he staggered down the stage, and it was Sui Liangyi who supported him.

"These people will not understand our efforts." Sui Liangyi said to him, "Brother, we can prove our value to them."

Weng Yuhua looked at this junior who had chosen the same path as him, and he felt a strong resonance.

Then it dawned on him.

If there is no data, then they will come to count the data.

Without examples, they went to crack one case after another and study each prisoner one by one.

They will face the urban crowd and make technical summaries to put those superficial theories into practice.

With so many people in the city, some of them will be potential murderers.

If they can get these people out ahead of time, that's the best way to prove that Criminal Minds has utility.

The original idea was put forward by Weng Yuhua, but the specific organizer was Sui Liangyi.He quickly recruited Wang Shaogu from the Huadu General Administration to help them with the layout, and he also recruited Zhang Junzhi, who also studies psychology, to do the actual operation.

They selected the site here, rebuilt an unmanned dilapidated factory building, and listed it as the 372 Research Institute with the street number, and soon started to develop it.

Weng Yuhua's original idea was to make achievements to let outsiders know, so all kinds of processes can be simplified... At the beginning, 372 Institute of Psychology was used as a criminological data reserve, and a psychological monitoring agency was established of.

Then they began to absorb social funds for research under the guise of psychological research.

At that time, with the help of Wang Shaogu's relationship, they got the cooperation of the school to conduct psychological screening for students and register potential high-risk groups.

Weng Yuhua admitted that they were a little eager for quick success, and their operations were not standardized.

But he didn't expect that what happened later...

There is no right or wrong in science and theory, but when the operator has evil in his heart, disaster will come.

Weng Yuhua clenched his cane tightly. After 20 years, he gradually realized that his choice back then had raised a huge monster.

Their success is based on one life after another.

Their feet have long been stained with the blood of innocent people.

The establishment of 372 Institute of Psychology is like opening Pandora's box.

At first, Weng Yuhua didn't personally know how those people make the research institute run. He just got some data and saw the processed data.

Later, when he found that something was wrong, Sui Liangyi told him that he only conducted some psychological research to draw conclusions and data, and it is not recommended to make everything public.

He believed Sui Liangyi's lie, thinking that the matter was not serious.

Until one time, he came to Huadu in person, saw the research institute built by his younger brother, saw the test records of the research institute, and learned about the people inside...

Knowing the pros and cons of it, Weng Yuhua was shocked.

At that time, the domestic environment had just improved, and criminal psychology was getting more and more attention. He had already become famous, published many papers at home and abroad, and won the support of many leaders.

As an expert in this field, he began to be afraid and began to think about how to deal with the 372 Research Institute.

He knew that if the 372 incident was exposed, not only would he fall from the altar and be subject to controversy, but he would also be punished and legally sanctioned.

At this time, Sui Liangyi came up with the idea to use the fire to destroy all relevant evidence, and claimed that Wang Shaogu would erase all traces.

By coincidence, he agreed, and even used some of his connections to block related news.

But later, he discovered that in some cases involved in the investigation, Sui Liangyi was always able to find out the truth and obtain the criminal's information at the first time.

It was only then that he realized that he still had contact with those people in the research institute back then...

And everything that happened in the research institute was not as simple as what Sui Liangyi said.

He has already become an accomplice to the evil.

Weng Yuhua has suffered, panicked, struggled, helped hide the truth, and tried to annihilate everything in the past through various legal and illegal means. He does not want to admit that this is a disaster caused by his ignorance.

In the end, when he finally wanted to expose all this, he was threatened by Sui Liangyi because of his daughter and his own life, and became his puppet.

When he found out, he had already been plunged into darkness, and he could never turn back.

Weng Yuhua sat there in a daze, while Sui Liangyi took out his mobile phone and tuned to the scene of the meeting.

The time was just right, and the following would be the part where Su Hui received the award.

Sui Liangyi stared at Su Hui on the screen, he came to the stage with a cane in his hand, and took the trophy from the leader.

The award presenter said the set of rhetoric he heard before...

At first, Sui Liangyi's brows were furrowed, but then they relaxed, and the corners of his mouth twitched slightly, waiting for the upcoming scene.

At this moment, a loud bang suddenly sounded, and the camera was directly shattered, and then fell to the ground.

The fire ignited, the building collapsed, smoke and dust were everywhere, and the scene was in chaos.

The screen is no longer visible, but someone's screams and cries for help can be heard.

"Mr. Su!"

"Su Hui..."

"Help!"

"Call the emergency number!"

With the smile on Liangyi's face gradually getting bigger, appreciating everything, the person who made him restless finally died.

Hearing a loud noise in the video, Weng Yuhua froze for a moment.

He broke free from the memories, raised his head and looked at Sui Liangyi who was laughing hysterically: "You still do it!"

There will be special people and companies responsible for security at the public security meeting, but for Sui Liangyi, who is familiar with the venue, I'm afraid he has already arranged for people to mix in and make a deceptive arrangement.

Sui Liangyi snorted coldly: "Brother, you understand me."

He knew him and his viciousness, so he must do his best to kill Su Hui.

Not only because Su Hui might find out the truth, but also because of the strong jealousy in his heart.

Jealousy, one of the seven original sins of human beings.

For Sui Liangyi, intense jealousy is like a beast gnawing on flesh and blood, biting him bloody all the time and driving him crazy.

Originally, after Zhang Junzhi's death, Sui Liangyi planned to hide in silence for a while, but these recent events, those praises and awards for Su Hui, made him unable to bear it any longer.

Weng Yuhua lowered his head sadly: "You thought I was better than you, so you approached me and ruined me. You thought Yu Yan was valued, so you asked someone to kill him. You repeatedly obstructed the students and newcomers below you, no Let them have any chance to stand out. Su Hui didn't die two years ago, yet you did it again..."

Sui Liangyi's face turned ferocious: "Brother, I am protecting you, and you know very well that if you keep your favorite student here, he will investigate all the truth sooner or later. The police will find out that you founded the 372 Research Institute. For the sake of the overall situation, all those who try to uncover this matter must die! Only when he is dead can we be safe..."

Weng Yuhua smiled wryly: "Do you think the police will believe that I, a semi-crippled old man, is directing everything behind the scenes?! I am only doing it for academic research, and everything is clearly done by you. If it wasn't for you, how could the 372 incident happen?" developed into what it is now..."

It was he who misunderstood his junior brother. He had profiled so many criminals and written so many reports, but he didn't realize that the people around him were actually the scariest and most dangerous.

After getting along for many years, Weng Yuhua discovered that his junior has no human empathy, but is good at subtle camouflage.

Facing the murderer, he will show hatred, and facing the victim, he will show regret.

But all this is acting!

It's all faked!

He has a strong learning ability and can pretend to cry, pretend to laugh, and pretend to be all human emotions.

In his usual communication, he made it impossible for anyone to see anything abnormal.

But in his heart, he was not moved by anything.

He could wipe away his tears at any time, showing a cold expression.

Good at disguising himself, understanding those of the same kind, with evil thoughts in his heart.

He is a more terrifying demon than those murderers with knives and guns!

Sui Liangyi said: "Don't worry, I will find a solution."

Weng Yuhua's hands were cold: "Now both Wang Shaogu and Zhang Junzhi are dead! What are you going to do next?"

The people responsible are gone, and the police will find them soon, and these things will be exposed soon.

"But senior brother, you are still there..." Sui Liangyi said with a smile.

Weng Yuhua tremblingly said: "You... you are not afraid that I will tell the police what you did?"

Sui Liangyi said: "Brother, if you wanted to expose this matter, you would have said it long ago, and you would not let the matter develop to this point today. Didn't you also clarify a lot of theories through those experimental results? You Didn’t you also enjoy those stolen money and bonuses, which improved your status in the police circle? You founded 372 back then, but now something is wrong, if you are going to die, who do you think will die first?”

Weng Yuhua lowered his head and fell silent.

He regretted so much that he didn't come forward to expose the incident when the incident was not so serious at the beginning, but now, he has already fallen into the quagmire.

If there is an investigation, he will be ruined. This madman will take revenge on his family crazily.

They are grasshoppers tied to a rope.

Sui Liangyi continued: "Brother, don't be afraid. We have money, power, connections, and pawns in our hands. We have destroyed all the materials and files. They won't have evidence, and they can't prove that we are with you. 372 is related. I also chose a scapegoat for the bombing, and we will never be found out.”

Over the years, they have dragged some people into the water in various ways.

In order to avoid joint and several liability, those insiders kept secret about 372 and tried their best to cover up the truth.

Sui Liangyi smiled and continued: "So brother, protecting me is protecting yourself. Those people are inherently criminal, and I just used some means to catch them in advance. We obtained them by arresting them." Today’s position, in order to make our theory accepted by more people, and to make criminal psychology go further, these sacrifices are worth it.”

Weng Yuhua bowed his head with a gloomy face: "What is your plan?"

Having been a partner for so many years, he knows Sui Liangyi well. Although he is crazy, he will always take his own way of retreat and retreat completely.

Sui Liangyi said: "Now that Su Hui is dead, no one in the Huadu General Administration is capable of finding out the truth. Next, we, as expert consultants, can apply to the department. We must intervene in the investigation of this case and help Su Hui find out the truth." The real murderer. Let's take over the case so that everything can be leveled out. Only then can we be truly safe."

Once they become investigators and ask for permission, it is up to them to write whether it is black or white.Sui Liangyi has already prepared the follow-up layout.

Weng Yuhua closed his eyes, considering his suggestion.

Sui Liangyi said: "The big leader in the hall, Director Gao, doesn't listen to you very much? The leaders are all here today, we will drive back now, you just need to play your role well - a teacher who lost his lover , leave the rest to me... This matter is like Yu Yan's death, no one will ever find out the truth."

Before he finished speaking, several police cars suddenly drove over at high speed, stopped beside their car, and surrounded the two of them.

Sui Liangyi raised his head in astonishment, and the one who opened the car door was Lu Junchi, the leader of Huadu Serious Crime Squad.

The person who followed him was Su Hui who should have died...
