Criminal Investigation Notes

Su Hui looked at the old man in front of him. There was no fear on his face, and his voice was still calm: "But you have been arrested by us now."

Dai Yuansheng is like a caged animal whose claws and claws have been pulled out by hunters.

Hearing Su Hui's words, his expression twisted for a while, and then he gradually relaxed and returned to calm.

Su Hui was right, being out of temper could not change his current situation.

Without those tools, he is just an old man, unable to kill any more.

Dai Yuansheng looked like a deflated puffer fish, with lowered brows and eyes, hunched back, and returned to his usual appearance.

He finally said: "I was born a bit strange. Some people are naturally suitable to be a doctor, and some people aspire to be a scientist. I have determined since I was very young that I will be a natural killer. I have to see someone die. I'm comfortable, I'm content with people's deaths."

Su Hui asked: "Have you ever been to the 372 Research Institute? When did you enter there?"

Dai Yuansheng's expression changed slightly when he heard this, and he continued: "Anyway, I've been caught now, and I don't mind cooperating with the police and telling you some truths. I was over 40 years old when I went there, I still remember a little bit, it was more than ten years ago, when my mother was not dead, she begged me on her knees and insisted on letting me go."

"What will they do there?"

Dai Yuansheng's voice was a little hoarse: "In the beginning, they made me think that they are the ones who understand us and respect us, and will not treat us as different. They asked us to cooperate with their work, registered my information, and began to ask I ask all kinds of questions and fill in all kinds of papers, by the way, they will give us money, two hundred each time, and more if we cooperate to do something."

It sounds like it's collecting information. If it's just doing this, it sounds like an ordinary research institution here, except that the research objects are psychopaths.

Su Hui continued to ask: "Is there not only that, is there anything special about what they do?"

Dai Yuansheng paused and said: "Yes, these are just superficial phenomena. I met a man there. After everyone got acquainted with each other, he began to communicate with me more deeply, allowing me to further enrich my fantasy. He even showed me some other pictures and cases. He would give me advice and tell me what I should do to satisfy myself and release my accumulated emotions.”

This is inducing...

"For example, how to do it?"

"For example..." Dai Yuansheng's Adam's apple rolled, "They will provide us with rabbits, mice, and cats, and observe how I kill those animals."

Su Hui leaned forward slightly, put his hands on his chin, and looked at the old man in front of him: "Will he let you extend these behaviors to humans?"

Dai Yuansheng nodded: "For example, he asked me to name one of my relatives for one of the rabbits, and then asked me to execute it." Then he continued: "He also has a complete set, which looks like that. The theory of the matter, what... is that nature has written our DNA, and those of us who have no emotions are more suitable for war than ordinary people, and are more able to survive in harsh environments. I am the ultimate human evolution direction."

"Do you believe this?"

Dai Yuansheng shook his head: "He is very persuasive and eloquent, but I will not believe these naive and naive statements, but I used to believe the money he sent. Because of the money, many parents would put the strange little ones at home. Send the child there. The people there will give us some medicines for free and provide me with information about other people. Only after I got to know them did I know that there are people in the world who are just like me..."

Hearing these words, Qiao Ze frowned slightly, finding it unimaginable. Even though he had a voice recorder and a video recorder, he still quickly recorded it in his notebook.

"...They know my peculiarities, what I have done, and what I want to do. After the fire broke out in the research institute, I lost contact with them..." At this point, Dai Yuansheng changed the subject .

"But many years later, they contacted me again, asking if I would like to participate in a bombing case, and said they would pay me a large sum of money... I chose to agree to them at that time."

Su Hui asked softly: "Your identity in it is not only that."

Dai Yuansheng nodded: "Yes, I am not only a participant, but also Song Lanen's supervisor. I am responsible for supervising his every move and reporting to those people at any time. That adult once mentioned some things to me." Dai Yuansheng said Here, the speed of speech was slowed down, "He wants to create a case that makes it impossible to find out the truth."

Under the radiant light, Dai Yuansheng's face was pale, his skin was old, his fingers were dry and thin, and they looked a little glaring.

Su Hui narrowed his eyes slightly. He had never felt so close to the people behind the scenes.

What is the other party's purpose?To embarrass the police and make them enemies?

Su Hui suddenly realized one thing, the other party was suspicious of Song Lanen.

Obviously, their control over Song Lanen is not that great.

He continued to ask: "How many people are there in total?"

Dai Yuansheng shook his head: "I don't know, we communicate through a single line every time."

"Do you know the identity of the person behind the scenes?" Su Hui asked.

Dai Yuan laughed: "How could a little person like me know this? I don't know his specific name." He continued: "I only know that that person, or that group of people, they have power, money, Powerful. In their eyes, we people are like ants, not worth mentioning."

Speaking of this, Dai Yuansheng rolled his eyes and looked at Su Hui: "Among them, there are also people from your police."

What he said partially overlapped with the recording of his conversation with Chen Xuexian that Su Hui had found before.

Su recalled what Yao Fei said, and further gathered the known information.

In Huadu, there are indeed some people who are secretly cultivating these murderers.

The people behind those people hold the secrets of these murderers' hearts, and will also hint to them that calling the police is useless.

Those serial killers have become their puppets and can be used by them.

They are also aware of the existence of the Behavior Analysis Group, and have even been using them as imaginary enemies, with the goal of destroying them.

When Dai Yuansheng said these words, Tan Ju, who was sitting in the observation room, was shocked.

Although Su Hui had told him some of his speculations before, he was still very surprised when he heard Dai Yuansheng say it himself.

As the leader of the Huadu police, he took over the Huadu General Bureau seven years ago. How could he know nothing about such things?

Tan Ju pondered for a moment, his brows were furrowed, and he suddenly remembered something.

After Xie Qiu's death in the Xisha case back then, Deputy Bureau Wang had volunteered with him to continue investigating the case...

He said to the police officer waiting on the side: "Where is Deputy Director Wang?"

"At six o'clock, I said I was not feeling well, so I went home." Deputy Director Wang had a heart attack, and occasionally asked for leave, which was well known in the General Administration.

After six o'clock, it was time for them to hunt down Song Lanen.

"Go and contact him."

"Yes!" The police officer on the side quickly walked out of the observation room.

Tan Ju frowned and thought, could it be that the person hiding among the police is Deputy Bureau Wang who usually keeps a low profile?

At nine o'clock in the evening, a black car parked quietly on the outskirts of Huadu.

This is an open space in a wetland park.

The park is open, people will come to play during the holidays, and photography enthusiasts will come to shoot migratory birds.

But on weekday nights, due to inconvenient traffic, few people come.

Now, it's dark and quiet here.

The driver stopped the car and turned on an orange light: "Get out of the car, he is waiting for you in front."

Song Lanen opened the car door, the night wind was blowing, and the temperature had already dropped. Without his coat, he felt a little cold.

Song Lanen put his hands in his pockets and walked forward to a streetlight.

The black car drove away quickly, and was not ready to take him away...

A man stood there, saw him coming, and turned his head: "Song Lanen, long time no see, have you completed your task?"

"I have let Bi Shanyu sneak into the General Administration, but I haven't received any further news." Song Lanen looked at him.

"Bi Shanyu?" The man chuckled, "How naive you must be, you were cheated and still counting money for others, that person is the police..."

"Impossible..." Song Lanen's first reaction was to refute, but then he calmed down, no wonder he didn't receive any news.

The man sighed: "I gave you a chance, but you failed..."

Song Lanen sneered: "To you, I have no use value, right?"

The man looked sideways at him, pulled out a gun, and aimed it at him.

"I didn't intend to complete this mission! I just wanted to see you..." Song Lanen sneered and pulled up his clothes, revealing the bomb strapped to his waist. "I've had enough of this kind of life!"

This thing is exactly the same as the one that killed Xie Qiu two years ago.

Song Lanen said tremblingly, speaking quickly: "During the past two years, I have thought it over clearly. You didn't prepare for us to retreat in the first place. You made up deceitful lies about sending us abroad! The fine sand case It's a well-arranged case. If I hadn't been locked up, I'm afraid someone from you would have cracked this case. We people are just a bargaining chip for you to get promoted and raise your salary..."

Although he is a devil, he doesn't like the feeling of being used.

Xie Qiu died. If he hadn't been imprisoned by Lan An for two years, he would have died a long time ago.

He still remembered that the first time he came into contact with the man in front of him was when he was ten years old. At that time, his adoptive father heard that Xie Qiu was seeing a doctor in the 372 Research Institute, and there would accept some children who behaved strangely and unreasonably, so he sent him there too. .

Those people were not the ones who saved them, but the demons who threw him into hell.

He hates these people, because of their existence, his life has been changed.

As he said that, he took out the remote control from his pocket, and then pressed down hard with his thumb...

Now that he can't live anymore, no matter which side it is, he will not be kept alive.

He has made so many bombs, except for the test, he has never seen the scene of the explosion.

Today at the last moment, he wanted to take a look.

It was the perfect combination of flame and power, enough to tear a person's body apart.

The choice of life and death is in the blink of an eye.

At this moment, he thought of getting to know Qiu.

Although the heart has been paved for a long time, but at the last moment of life, the heart is blank and extremely peaceful.

But after Song Lanen pressed the button...

The night sky was quiet, the moon was shining brightly, and nothing happened.

Song Lanen's eyes widened in disbelief, his face froze.

"Song Lanen." The man called out his name, and he approached him, "Do you really think that old man Dai Yuansheng has been looking for you tirelessly for two years? I provided you with the materials for your production, so I am naturally very happy Know what you want to do with those things."

Song Lanen understood: "Have you changed the raw materials?!"

He was walking around Huadu with this inexplosible bomb for a long time. At that moment, he felt like a jumping clown.

"Only a small part was changed. If you use the remote control device instead of the timing device, you will definitely need it." The man said, "You've also used up your spare combustion bottles, right?"

Song Lanen lost all his strength in an instant. He came here today because he wanted to die and die with this person.

It's just a pity that he still missed a step...

The man looked at him indifferently: "We accepted your gift, and someone will replace the original." Then he raised the gun in his hand, "Now you, you can die..."

Song Lanen was stunned for a moment, and then rushed over...

boom!

A gunshot in the night sky startled the birds in a wetland.

Then the night returned to silence, as if nothing had happened.

The man took out his mobile phone and dialed a number: "Hey, I've already dealt with Song Lanen."

Something was said over the phone.

The man said: "Okay, let's meet later."

After he finished speaking, he carefully wiped off his own footprints, put on gloves and foot gloves, walked to the corpse, knelt down, and took out a knife...

On the outskirts of Huacheng, several police cars are still searching the area.

"Lieutenant Lu, in the Wetland Park not far from you, someone called the police and said they heard gunshots."

"Got it!" Lu Junchi quickly turned the car around.

Police soon arrived, and they found the body of a man deep in the park.

Lu Junchi quickly walked over to check. Song Lanen was lying on the ground on his back, his eyes were still open, his chest was blood red, and the wound was very messy.

Such a way of dying is a bit too cheap for him.

Looking into his eyes, Lu Junchi remembered the moment when he confronted him before.

He hurriedly reported to the General Administration: "It has been confirmed that the body is Song Lanen. It feels like a gunshot wound, but it was destroyed by a knife. It may be to avoid a ballistic test. The murderer dug away the bullet. The body has been dead for more than 10 minutes, and the bomb is not here. It may have been taken by someone else."

The principal culprit in the Xisha case was confirmed dead, and the clues about the person behind the scenes were cut off again.

Tan Ju in the command room seemed to have aged a few years in an instant.

Su Hui lowered his head and sat aside, his fingers rubbing the cane, exhaustion swept over him.

It was difficult for him to confirm for a while whether they had won or lost this battle.

Based on Dai Yuansheng's confession, Su Hui could probably guess what Song Lanen was going to do.

What prompted him to do so was not the goodness in his humanity, but the truth behind the scenes and the unwillingness in his heart.

In any case, the death of that demon is something to be thankful for.

He can no longer make those deadly bombs.

After ten o'clock in the evening, Lu Junchi finally collected his team and returned to the headquarters. The day's work was coming to an end.

Tan Bureau announced that it will start a special investigation of 372 cases from now on.

All unsolved matters of the fine sand case will also be merged into this case.

Since Yao Fei was also related to the case, he was detained by Bureau Tan under the pretext of cooperating with the investigation, and he was arranged to stay and sign some temporary confidentiality agreements and working documents for cooperating with the investigation.Let him join the investigation of Project 372 as an informant.

After a thrilling day, when he arrived downstairs, Su Hui's legs became weak, and he almost fell to his knees. Lu Junchi helped him from behind, and he stood still. Then he covered his mouth and coughed again and again.

Lu Jun didn't drive for a long time. He used his mobile phone to call a taxi at the gate of the main office.

Su Hui paused for a moment and said, "What if we haven't found that bomb?"

He once personally experienced the scene of an explosion, and now thinking about it, he still has lingering fears.

Lu Junchi comforted him and said, "We will work hard to find it." He paused and said, "We will find out all the truth."

Although it was already late at night, there were still quite a few people busy in and out of the headquarters. Su looked back at the hurrying people, feeling a little tired.

The undiscovered bomb hung over his mind like a dark cloud.

They haven't found who was behind the bomb removal yet.

They don't know much about 372, what kind of crazy opponents they will be...

Lu Junchi took off his coat and put it on him: "I'll take you to the hospital for another checkup tomorrow."

Su Hui said, "I'm much better, but I'm still a little weak..."

Lu Junchi insisted: "It's all arranged, and I've talked to Bureau Tan about it."

Su Hui didn't say anything, the car arrived soon, and the two got into the taxi.

Su Hui buried his face in his collar, smelling the smell of Lu Junchi above, his head was still dizzy.Lu Junchi wiped off a bit of dust on his cheeks with his fingertips, pulled him, and he leaned on his shoulder.

On the street, traffic drove past them.

After waiting for a gap in the red light, Su Hui looked out the car window. The two lovers had finished their supper and passed by arm in arm. There was a burst of laughter; the husband who was returning home saw his wife pushing a stroller to pick him up; An elderly couple walking with each other supporting each other.

This is a very common picture in life.

There are many high-rise buildings, and lights of various colors are flickering. From a distance, they look like stars.

The city is bustling and peaceful.

Many people don't know what a thrilling day it is, and what many people have paid for the tranquility of the city.

After a while, Lu Junchi answered the phone and said to Su Hui, "I just heard a good news and a bad news, which one do you want to hear first?"

Su Hui thought about it: "Good news."

Lu Junchi said: "The hospital called just now, and Lao Xing has woken up."

It is indeed good news that Xing Yunhai finally woke up after being in a coma for many days.

Su Hui felt a little better, and he blinked his eyes and asked, "What about the bad news?"

"It's not completely bad news." Lu Junchi said, "Deputy Director Wang was just discovered and hanged to death in his own home."
