Criminal Investigation Notes

When he was in school, Weng Yuhua used to treat Su Hui very well.

A few years ago, there was no special criminal psychology department in China, and the course of criminal psychology was only set up as a sub-course in the criminal academy. Weng Yuhua teaches the course of criminal psychology. He has a very good understanding of the relevant history at home and abroad, and also has many original opinions in academic aspects.

During the university period, Weng Yuhua took good care of Su Hui and also had the intention of cultivating him.

He took Su Hui to publish his first paper in a core journal and introduced him to relevant academic circles.

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 also asked Su Hui if he would like to stay in school to teach.

At that time, Su Hui was eager to apply what he had learned, and wanted to go to the front line, Mr. Weng did not stop him, and supported his choice to enter the police station.

When Su Hui was about to graduate, he extended an olive branch to him in several places. Some of them had higher salaries than Hua. After meeting with Yu Yan twice, Su Hui finally chose to work in Huadu.

When teachers and students parted ways, many years passed.

Now that we meet again, it has been vicissitudes of life, and things are different.

In recent years, Su Hui has also heard some news about Teacher Weng.

Mrs. Weng's wife died three years ago.

Since Weng Yuhua suffered a stroke half a year ago, his legs and feet have not been very agile. Since then, he has relied on a wheelchair for important activities. Weng Yuhua's junior brother Sui Liangyi has taken good care of him and has been by his side. The two are not only brothers and sisters, but also friends in life. They have helped them all the way to the present.

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

Su Hui could hear that Sui Liangyi was somewhat critical of the results this time around.

He has won awards that seniors like them haven't won yet.

Weng Yuhua didn't look very good, and was a little tired. He said: "The back waves of the Yangtze River push the front waves. This is the truth since ancient times. Su Hui has always been my proud disciple."

Then he turned to look at Su Hui, as if to explain for Sui Liangyi: "Su Hui, you have done those things, solved so many cases, suffered a lot of hardships, and you deserve this kind of reward. you are happy."

"Thank you Professor Sui, thank you Teacher Weng." Su Hui said and 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'll wait for the afternoon. After the awards ceremony, I would like to invite you to dinner."

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

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

His heart moved, and he stretched out his hand to take out the tie clip and clip it to the tie.

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

It seems that they are ready to leave after participating in their own session.

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

Sui Liangyi pushed Weng Yuhua and walked past the venue. Since the official opening had not yet begun, many people were still chatting.

The host on the stage rehearsed the award speech: "With his superb criminal profiling skills, through careful 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 due diligence."

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

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

"Hey, Consultant Su is really good. But this time has indeed dragged on for a while. Aren't you going to apply for expert assistance from the provincial government?"

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. Yes, the real culprit behind the scenes has not yet been found, 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 the other leaders present at the meeting.

Soon, the whole process was over, and at the hour, the leaders took their seats, and the meeting officially started.

The meeting started with the leaders giving speeches.

Then the leaders of each general bureau made a summary.

When the awards came, the winners came on stage one by one.

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

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

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 session, and there was a half-hour break in the arrangement of the meeting.

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

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

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

Once he forgot that his wife even took a taxi to the venue. Su Hui was there at that time, watching the couple adjust 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 it.

The car stopped suddenly.

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

Weng Yuhua frowned and raised his head. This is a secluded riverside and looks a little familiar.

Sui Liangyi said: "Senior brother, do you still recognize where this is?"

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

He adjusted his glasses: "Yes. We used to make decisions here when we were young."

For him, it was a bad memory.

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

Weng Yuhua remembered that the reason why he wanted to build the 372 Psychological Research Institute was because at the summary meeting, as a police consultant, he gave a work summary and presentation to all the leaders.

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

At the end, the leader gave him a light-hearted sentence: "Yuhua, your work is progressing very well, and I also support you to do these emerging theoretical studies, but what you said, without the support of data and examples, also There are no results to come up with. I hope that you will be able to put everything into practice."

The people below were talking about it: "This set of methods is all foreign, and in China, it will be difficult to adapt to the environment."

"The domestic security is very good, and 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 just talk on paper. You can just give lectures in schools, and they can't be applied to reality at all."

"Yeah, so his adviser is only a nominal one, and the police below are not willing to cooperate at all."

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

Listening to Weng Yuhua, his face became paler and paler.

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

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

He started from scratch, one of the first people to study criminal psychology, and he was facing a wilderness, shouldering heavy responsibilities, and striding hard.

He once fantasized that everything would blossom and that profiling technology would be applied to every case and play a huge role.

But everyone looked at him, their eyes were puzzled and rejected, they seemed to be listening to a fantasy.

Is this a waste of time?

Is it pointless?

Do we really need to do relevant research?

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

He wanted to give advice to those police officers, but no one was willing to listen to his analysis.

Weng Yuhua was confused.

Want to give up?

Or look at it all and be a good gentleman who only says the right things?

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

He is already forty, how far can he go on this road?

Weng Yuhua took a breath.

At that time, he staggered off the stage, and Sui Liangyi 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 the younger brother who had chosen the same path as him, and he felt a strong resonance.

Then he was enlightened.

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

If there is no example, they will solve one case one by one and study one prisoner one by one.

They will have to face the urban crowd and conduct technical summaries to turn those vain theories into reality.

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

If they can identify these people ahead of time, that's the best way to prove criminal minds have utility.

The original idea was proposed by Weng Yuhua, but Sui Liangyi was the person in charge. He quickly brought in Wang Shaogu from the Huadu General Administration to help them with the layout, and also brought in Zhang Junzhi, who also studies psychology, for practical operations.

They chose this location, rebuilt a dilapidated factory building with no one, and listed it as the 372 Research Institute with a road sign, which quickly started.

Weng Yuhua's original idea was that the result was to be known to outsiders, so the various processes could be simplified... At the beginning, the 372 Psychological Research Institute was established as a criminology data reserve and a psychological monitoring agency. .

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, carried out psychological screening for students, and registered potential high-risk groups.

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

But he didn't think about what happened later...

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

Weng Yuhua clenched his cane, and it was only twenty years later that he gradually realized that his choice back then had raised a huge monster.

Their steady progress is stepping on one life after another.

Their feet were already stained with the blood of innocents.

The establishment of the 372 Psychological Institute is like opening Pandora's Box.

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

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

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

Until one time, he personally came to Huadu, saw the research institute built by his junior and junior brothers, saw the test records of the research institute, and learned about the people inside...

Weng Yuhua knew the pros and cons, and was shocked.

At that time, the domestic environment was just getting better, and criminal psychology was getting more and more attention. He was already famous, he 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, he would not only fall from the altar and be subject to controversy, but would also be punished and punished by law.

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

In a strange way, he agreed, and used some of his own connections to block relevant 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 information about the prisoners 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 what happened in the research institute was not as simple as Sui Liangyi said.

He has already become an accomplice to the abuse.

Weng Yuhua has suffered, been frightened, struggled, helped hide the truth, and tried to annihilate everything in the past through various legal and illegal means. He did not want to admit that it was a disaster caused by his lack of knowledge.

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

By the time he found out, he had already been plunged into darkness and could never look back.

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

The time is just right, and the following will be the link for Su Hui to accept the award.

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

The presenter said the same rhetoric he heard before...

At first, Sui Liangyi's brows were wrinkled, but then, they stretched out, 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 by the shock, and then fell to the ground.

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

The picture is no longer visible, but someone can hear screams and cries for help.

"Mr. Su!"

"Su Hui..."

"Help!"

"Call the ambulance!"

The smile on Sui Liangyi's face gradually widened, admiring everything, the person who made him restless at night, finally died.

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

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

There will be a special person and company responsible for security at the public security meeting, but for Sui Liangyi, who is familiar with the venue, I am afraid that people have been arranged to mix in and make arrangements to hide from the public.

Sui Liangyi snorted coldly, "Senior brother, you know me well."

He knows him and his viciousness, and 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 mankind.

For Sui Liangyi, intense jealousy is like a beast that eats flesh and blood, biting him with blood all the time and driving him crazy.

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

Weng Yuhua bowed his head sadly: "You thought I was better than you, so you approached me and destroyed me. You felt that Yu Yan was valued, so you found someone to kill him. Let them have any chance to emerge. Su Hui didn't die two years ago, but you are doing the same trick again..."

Sui Liangyi's face turned hideous: "Senior brother, I am protecting you, and you are very aware that if you keep your proud disciple, he will investigate all the truth sooner or later. The police will find out that the 372 Research Institute was founded by you. For the sake of the big picture, everyone who tries to uncover this must die! We are only safe when he dies..."

Weng Yuhua gave a wry smile: "Do you think the police will believe that it is me, a half-crippled old man, who is directing everything behind the scenes?! I am only doing academic research, and everything is clearly done by you. If it wasn't because of you, how could 372 happen? It has developed into what it is now…”

It was he who misread his junior brother. He profiled so many murderers and wrote so many reports, but he didn't realize that the person around him was actually the most terrifying and dangerous.

After getting along for many years, Weng Yuhua discovered that his younger brother had no human empathy, but was good at subtle disguise.

In the face of the murderer, he will show hatred, and in the face of the victim, he will show regret.

But it's all about acting!

It's all made up!

His ability to learn is very strong, he will pretend to cry, pretend to laugh, and pretend to be all human emotions.

In the usual communication, he can't see any abnormality.

But his heart was not moved by anything.

He could wipe away his tears at any time and show an icy look on his face.

He is good at disguising himself, understands those of the same kind, and has 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 way."

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

The culprits are no longer there, the police will soon find them on their heads, and these things will soon be exposed.

"But Senior Brother, you're still here..." Sui Liangyi said with a smile.

Weng Yuhua said in a trembling voice, "You...Aren't you afraid that I will tell the police what you did?"

Sui Liangyi said: "Senior brother, if you wanted to expose this matter, you would have said it long ago, and you will not let the matter develop to this stage. Didn't you also clarify a lot of theories through those test results? You Didn't you also enjoy those stolen money and bonuses, which improved your status in the police world? 372 was founded by you back then, and now something goes wrong, if you want to die, who do you think will die first?"

Weng Yuhua lowered his head and remained silent.

He was extremely regretful. He didn't come forward to expose the matter when it wasn't so serious at first. Now, he has long since fallen into a quagmire.

If he wants to investigate, he will be disgraced, this madman, and his family will be madly revenge.

They are grasshoppers tied to a rope.

Sui Liangyi continued: "Senior brother, don't be afraid, we have money, power, connections, and chess pieces in our hands. We have destroyed all the materials and files, and they will not have any evidence to prove that we are with 372 has something to do with it. I have also chosen a scapegoat for the bombing, and we will never be found.”

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

In order to avoid joint and several liability, those in the know kept a close eye on 372 and tried their best to cover up the truth.

Sui Liangyi continued with a smile: "So senior brother, to protect me is to protect yourself. Those people are born to commit crimes, and I just used some means to catch them in advance. We obtained them by arresting them. Today's status, in order to make our theory more accepted, to make criminal psychology go further, these sacrifices are worth it."

Weng Yuhua lowered his head with a gloomy face: "What's your plan?"

Having been his partner for so many years, he knew Sui Liangyi. Although he was crazy, he always followed his own path of retreat and retreated completely.

Sui Liangyi said: "Now that Su Hui is dead, no one from the Huadu General Administration has the ability to find out the truth. Next, as expert consultants, we can apply to the hall, and we must intervene in the investigation of this case and help Su Hui find the truth. The real culprit. We take the case so that we can settle everything. Only then can we be truly safe."

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

Weng Yuhua closed his eyes and considered his suggestion.

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

Before he could finish his words, several police cars suddenly drove over at high speed, stopped beside their cars, and surrounded the two of them.

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

The person next to him was Su Hui, who should have died...
