Criminal Investigation Notes

There was a hint of coldness in the air.

Su Hui ignored Song Rongjiang and continued: "Then, it's time for the first case to happen soon. At that time, your secret love for Pei Weiwei deepened, so you mustered up the courage to do one thing, you went to her Confession. The sudden confession frightened the girl, and she refused in horror. Because to her, you are a stranger who she can't remember."

At present, there is no actual evidence to prove that Song Rongjiang knew Pei Weiwei.

Su Hui's assumption is false, and there is no empirical evidence.

But now he said it in a determined tone.

Such an assumption has never appeared in the previous police investigation. Su Hui's assumption disrupted the timeline of psychological crimes and deduced such a result, which he believes is the closest to the truth.

This result was not made up by him, but was deduced from clues after researching the case, understanding Song Rongjiang, and interviewing many people.

In the document Tan Bureau gave him, Lu Junchi had worked hard to call up the nighttime driving route of Song Rongjiang's vehicle for a long time. Among them, on weekends and Sunday nights, he would regularly appear at the gate of Pei Weiwei's school and near his home, which was also favorable circumstantial evidence.

Based on these clues, Su Hui speculates on the other party's psychology.

There have been many definitions of criminal minds for a long time.

The criminal psychology that Su Hui thinks and understands is not those mysterious theories, but when faced with a murderer, he can speculate on his past thoughts and predict his next move.

This is an unsubstantiated derivation. If these do not have a solid foundation, people who detect criminal psychology are like walking on a wire, and they may fall into the abyss at any time because of the wrong place.

But once this situation is true, there will be a road that did not exist in the abyss.

Among the countless possible pasts, deduce the only possibility, the only truth...

"During the period of rejection, you quarreled with the first victim, and then got angry and killed her... At that time, your killing idea was temporary, and your killing was analyzed psychologically. It's compensatory killing." Su Hui said in a deep voice, "You want to kill Pei Weiwei."

Song Rongjiang was no longer as calm as before. His hands were shaking violently. He no longer denied Su Hui's story, but emphasized it again: "I didn't **** want to kill her at that time."

Such a reaction is already a disguised acknowledgment of Su Hui's story.

And Song Rongjiang's words reflect a key point, what is "then"? Has his thinking changed over time?

Su Hui continued: "The death of the first victim was close to an accident. You were so angry that you committed murder. When you woke up, everything had already happened..."

"After that, your life was out of balance. You hurriedly dumped the body, knowing that you would be found by the police. Under this tension, you began to reminisce about the pleasure of the first killing, and found yourself enjoying it. So, you killed the second girl."

Su Hui said, observing Song Rongjiang with a hazy vision. He couldn't see his specific expression, but he could feel that his face was twitching gently every time he inhaled a cigarette, and his smoking frequency also increased. .

Su Hui knew that, and he said it again.

"When you were describing the second victim to me, there was an interesting sentence, that is, after you killed her, you felt 'she belongs to you'..." Su Hui probed and continued, " So after this time, you will be more clear about your intention to kill Pei Weiwei..."

When he said this, Su Hui deliberately slowed down his speech: "Because, you want her, it belongs to you completely."

At that time, Song Rongjiang should have understood that as long as Pei Weiwei was alive, there was an unbridgeable gap between them, and only when the girl died could they truly be with him.

But Pei Weiwei is different from other victims, she is like a treasure in his heart, that is a woman who belongs to him alone...

In the interrogation room, this is a psychological duel without a sword.

Su Hui said slowly: "So you had an idea at that time. You wanted to kill Pei Weiwei, but you didn't let everyone know. You even fantasized that after your own death, your soul can blend with her..."

"Shut up!" Song Rongjiang suddenly stood up, causing the desks and chairs to rattle. Those desks and chairs had long been nailed to the floor, and they trembled because of him, and they seemed to fall apart at any time.

Song Rongjiang suddenly found that he seemed to be caught in a subtle passive. If there was a poker game in front of him, his cards had already been played, and he had no idea what Su Hui was holding in his hand.

Su Hui raised his head to look at him, still calmly said: "Look, do I still know you a little bit?"

His next sentence pierced Song Rongjiang's mind more and more, "You chose Pei Weiwei because she is too much like Tao Li, and she is younger than Tao Li and closer to your memory..."

"The first two victims are Pei Weiwei's compensation victims, while Pei Weiwei is Tao Li's compensation victims. There is a double compensation relationship in this case."

"How did you know Tao Li?!" Song Rongjiang punched the table, his joints bleeding. The man in front of him was suddenly distracted, and Fang Cun began to be in chaos.

Song Rongjiang originally thought that few people knew about his relationship with Tao Li back then, and no one knows about it now. Even her name, he has been trying his best to avoid it and never mention it again.

After a few coughs, Su Hui continued: "There have always been many ways to classify serial killers. One of the most commonly used methods is to distinguish criminals by whether they are organized or not. The other is organized criminals, who have meticulous behavior and planning. , who are good at covering up their crimes, they will carefully choose each of their targets, and try to evade guilt. There is also an unorganized criminal, this type of criminal is very emotional, and the choice of the victim is more random, he kills It could be a random person you meet on the road."

"But serial killers aren't just these two extremes. More murderers are hybrid murderers, and those perpetrators change between organized and disorganized forms."

"An interesting phenomenon is that when an organized serial killer is discovered by the police, he tends to go into chaos and become disorganized. When an unorganized serial killer is pursued by the police, he starts to become more and more Be careful and learn to hide your crimes step by step."

Song Rongjiang is a typical representative of the evolution from unorganized crime to organized crime, and the target of his murder has also changed from the random crowd to Pei Weiwei.

"I also know one thing. After you killed Pei Weiwei, in order to recall that feeling, you have returned to the crime site more than once, that is, the place where you buried her." Su Hui did not answer his question. As he narrated, he lowered his head and took out a map of Huadu.

"Going back to the crime scene, which is what a lot of serial killers do, and going back there will help you better reminisce about the crime."

"The police have already checked your income records. Almost every few days, your rental income will suddenly decrease, while the amount of oil is increasing. According to the decrease in oil amount and income, this change is from It started before Pei Weiwei disappeared. I guess you were planning how to hide her body in those few times, you were looking for a place, and then you were digging the grave, killing people, and burying the body."

"A lot of evidence is enough to prove that you have been to the same place in the dark night, and according to the time and fuel consumption and the camera records along the way..." Su Hui said, unfolding a map of Huadu, he drew on the map a range.

When Su Hui said this, he raised his head: "The place where Pei Weiwei was killed is within this circle. And you will come to the place where you committed the crime again in the cold night, and reminisce there..."

Song Rongjiang looked down at the picture and swallowed, the area included where he buried Pei Weiwei, and he had visited her more than once, and Su Hui was right again.

Song Rongjiang admitted that no matter how strictly he guarded it, the person in front of him still opened his heart and peeped into his secrets. This feeling made him shudder...

He admitted that he was a monster, but why was Su Hui able to decipher the psychology of such a monster?

He is like a hunter who specializes in trapping them. Those lies and traps that have tried so hard seem to be insignificant tricks in front of him.

"Unlike the other two victims, this time the killing place was not in the car, but in a secluded and uninhabited place. You strangled her..."

"Because of this, there are no traces left on the car."

Under Su Hui's description, Song Rongjiang's thoughts seemed to return to more than a hundred days ago, when Pei Weiwei stopped breathing under his palm...

The weather in April was still a bit cold, but his heart was warm, and he touched her face repeatedly... He completely possessed the girl.

There was no emotion in Su Hui's voice, and the whole person was like an indestructible piece of ice: "After meeting Tao Li, I am more and more sure of this... You killed Pei Weiwei who looks very much like Tao Li, do you want to be with Tao Li? She is always together."

Song Rongjiang looked up at Su Hui. The man in front of him ripped open his chest step by step, as if he was using his hands to open his brain, how would he know? ! Those are facts that the police couldn't find after months of investigation!

Song Rongjiang's heartbeat was like thunder in his chest. He felt that Su Hui had gradually approached the answer that he had carefully hidden for a long time...

Do not! It can't be like this, he will die in just a few days, and Pei Weiwei is still there waiting for him...

A girl's sweet smile appeared before his eyes.

In this world, only he can know where she is!

Su Hui's voice was still in Song Rongjiang's ear and said slowly: "I checked multiple addresses, is it in the small park where you two dated? The West Mountain you climbed together? Or...the one behind your school. A walnut forest?"

"She is mine! No one can take her away!" When he heard the last location, Song Rongjiang suddenly rushed over like crazy. He pulled up Su Hui's collar, and Su Hui felt that he was being pulled vigorously. His back hit the back of the chair. After that, Song Rongjiang's hand grabbed Su Hui's throat.

She is completely his own!

Song Rongjiang's hands gradually tightened, Su Hui couldn't breathe for a moment, the thick palms pressed against his throat and blood vessels, it was a feeling of near death.

But there was no fear of death on Su Hui's face, he just looked at Song Rongjiang so calmly.

As if he was looking forward to this moment.
