Criminal Investigation Notes

It was almost twelve o'clock, Lu Junchi saw that the questioning was almost finished, and ended the conversation: "Ms. Li, thank you, the information you provided is very helpful, we will try our best to catch these robbers. If you think of anything else , or if you need anything, you can call me."

Lu Junchi and Su Hui left the flower shop, and Lu Junchi asked Su Hui, "Why didn't you speak before?"

Su Hui coughed a few times and said, "You asked a good question, and I have nothing to interrupt."

The scent of flowers in the flower shop just now was too heavy, and he was not comfortable breathing, as if those old injuries were recurring, every breath from his chest to throat seemed to be mixed with fine glass slag in his body.

He didn't want Lu Junchi to worry, so he paused and said, "Besides, there seems to be a mystery in this story, so I can't bear to interrupt it."

In any case, they finally obtained a lot of effective information, and they also learned more about the robber's method of attack.

Lu Junchi called the serious crime team and asked them to continue to pursue Yawen's ex-husband's confession, and asked Qu Ming to compare the suspect's characteristics with the list of fire survivors in China in recent years.

Qu Ming took orders immediately.

After hanging up the phone, Lu Junchi replied to Su: "I can't make it back at noon, let's go and have lunch."

Su replied: "I'm not too hungry." He had just finished drinking a carton of milk, and at this moment his mind was full of thoughts about what Li Yawen said just now.

Lu Junchi said: "Eat something even if you're not hungry. Is there anything you want to eat?"

Su Hui didn't bother to think, "Whatever."

Whatever, isn't this the most difficult dish to choose...

Lu Junchi felt helpless, searched the Internet a few times, and led Su Hui into a nearby Chinese restaurant.

When the dishes were served, Su Hui smelled them, and found that they were very fragrant. He lowered his head to carefully identify them, and found that the whole table was full of dishes he liked.

Su Hui didn't know when Lu Junchi remembered his preferences.

He said before that he was not hungry, but when he saw his favorite food, he couldn't help moving his chopsticks and eating quietly.

Lu Junchi felt that Su Hui in front of him was like an iceberg, with only a small peak sticking out of the water, making it impossible to see the underwater shape, and he was often unable to figure it out.Only by getting close can you walk into his inner world and understand what kind of person he is.

After a hasty lunch, Lu Junchi took Su Hui on the way back.

Su Hui said he was a little sleepy when he got in the car, and fell asleep after lying on the passenger seat for a while. Lu Jun didn't bother him, but he knew that Su Hui didn't sleep well. Did not sleep well.

The return journey was smoother than when we came here. At four o'clock in the afternoon, Lu Junchi's car finally got off the expressway and entered Huadu City.

Su Hui fell asleep all the way, rubbed his eyes for a while, and then straightened up the seat, making the corners of his eyes red.

Looking at his messy hair, Lu Junchi couldn't help reaching out to help him straighten it, and asked him, "Have you thought of anything after hearing Li Yawen's confession before?"

Su Hui said, "The murderer is killing people."

Su Hui was more like a meditative state than sleeping just now.

Those cases, cases, and incidents kept rolling in his mind, and he tried to straighten everything out.

The murderer is too cruel. This kind of cruelty does not only mean that they killed a large number of people, and the few cases they created were mostly exterminations. The location they chose was people's homes, but that they were killing their hearts.

Analyze the little secrets in everyone's life, tear apart the families they thought were harmonious in front of the victims, let those people's worlds collapse bit by bit, and take their lives away after they lose all hope .

The most beautiful thing in the world is love and affection.

Betrayal, life and death, these things are like buried mines, what they do is to detonate one after another in advance.

Destroy those good things for people to see.

How desperate those dead should be before they die.

Entering the urban area, the speed of the car slowed down, and there were many traffic lights.

The speed of the car was very slow, and finally Lu Junchi didn't have to worry about being distracted by discussing the case while driving. He asked again, "According to what we know now, can you analyze the murderer's psychology?" After asking this sentence, Lu Junchi immediately added, " I know that we will definitely find actual evidence, just as a reference..."

Su Hui saw that what he wanted to remind had already been said by Lu Junchi, and then he opened his mouth to analyze: "When I heard about the robber's question, I thought of a game model—the volunteer's dilemma."

This was the first time Lu Junchi had heard of the term volunteer dilemma.

"What is the Volunteer Dilemma?"

"The so-called volunteer dilemma means that among a group of people, one person needs to stand up and sacrifice himself, and the others will be safe. So is anyone willing to be this volunteer? How many people are willing to be this volunteer? ?For many years, people have tried to use mathematics and psychological factors to explain this problem and resolve the dilemma, but...the related game has not been well solved. "

Everyone hopes that heroes can jump out to protect themselves in times of crisis, but not everyone can protect others in emergencies.

Human nature is the hardest thing to judge and the hardest thing to control.

This game has spawned many experiments, but the results of many experiments are contrary to the predictions of the standard game.

Lu Junchi understood: "The robbers turned this problem on the family, and added a lot of conditions."

"Actually, the core of the problem is that when the family is in danger, as a family member, are you willing to sacrifice yourself to save your family?" Su Hui continued to analyze calmly, "The murderer regarded the intrusion into the victim's family as a crime. A killing game. The game is divided into rounds. The question in each round is whether you are willing to sacrifice yourself for your family."

"Assuming that the victim is only a husband and wife, then after the first round, there will be three situations. In the first situation, the husband and wife each bear a knife. In the second situation, the husband says he is willing to die for his wife, and the wife also wants her husband to die. , the husband suffers two stabs, and in the third case, the wife says she is willing to die for her husband, the husband wants his wife to die, and the wife suffers two stabs. The first situation is still relatively stable. In the latter two cases, people’s inner world It’s all going to be out of balance. Willing to die and someone wanting you to die are two different concepts. If the family is larger, the process will be more complicated.”

When they learn that their relatives will kill themselves, this is a great harm to the victim, and many people's ideas will collapse at this moment.

"If the first round is balanced, the murderer will start to reveal the secrets between the couple. In the relationship of family life, money problems, and friction in life, it cannot be smooth sailing. They will find out the contradictions in it. Point, zoom in, let the love between the victims gradually shatter. Accompanied by the pain, emotional breakdown, the second round, the third round... Once one of the husband and wife can't hold on, and says that he wants the other party to die, It would tip the balance."

Lu Junchi reacted and said: "That is to say, this is a cycle. If the balance is not broken, it will continue to enter the next game. Once the balance is broken, when two people say they want the other to die, they will be killed." ..."

It sounds like this is basically a proposition that no matter how you choose, you will be killed in the end.

Su thought about it and added: "The operating rules of this game are like a centipede game. The two participants take turns to choose. There are two options: cooperation and defection. If you choose cooperation, the cycle continues. Once you choose to betray, The relationship will break down."

Lu Junchi has heard this theory before, because this data model looks like a centipede, hence the name, and he asked again, "Why did those robbers do such a thing?"

When Su Hui said this, he lowered his head and focused, resting his sharp chin on his scepter and said: "I feel that one or more of those robbers, he or they, may have been betrayed. Feelings make them suffer from time to time. Those experiences of being betrayed have traumatized their hearts. They hate the betrayer, so they try to find more examples to prove that love and family affection are not reliable. They watch others repeat themselves They executed the traitors and got the pleasure of revenge. Therefore, they will choose those so-called loving victim families, test them, and then kill them."

After listening to Li Yawen's narration, Su Hui finally knew what the robbers were looking for.

They are using death to make up for the wounds in their hearts.

There is also an interesting pattern, the male robbers face women, and the female robbers face men.

Su Hui suddenly thought of something, and said to Lu Junchi, "Remind Qu Ming and the others that they not only want to investigate people with criminal records, but the current robbers may also be victims in the past."

Lu Jun responded late and sent a voice message to Qu Ming.

Su Hui continued: "There is a projection effect in psychology, which means that some people will attribute their own characteristics to other people. When those people have experienced the experience, in order to seek psychological balance, they will hope that other people's thoughts To do the same thing as them is to hope the same thing happens to others and make the same choices."

Lu Junchi asked: "Then you now feel that there is no solution to this problem and the cycle."

Su Hui lowered his head and frowned for a while, "Actually, once you abandon your family, you abandon yourself."

Lu Junchi: "You mean, if the victim can't bear the pressure and expresses his desire to kill the other party, it's actually a death sentence for himself?"

"That's one of the conditions for the robbers to kill." Su replied, "You can find that at the beginning, the husband and wife were not seriously injured. If you persist to the end, the two people have always believed in each other and are willing to sacrifice for each other. Hate the victim, threaten them, but don't kill them. Because at that time, the victim still has hope in his heart, and what happened does not match the experience of the gangster. If your desires are not satisfied, you will not get the pleasure of killing."

The robbers may be furious and anxious, but may eventually give up.

In the few families so far, except for Li Yawen and her ex-husband, the other victims were not spared, that is to say, no one persisted.

Most families broke the balance in the second round, either the wife retreated or the husband retreated, and only a few people persisted until the third round.

Among them, the one who persisted for the longest time may be a couple from outside the city. Before they died, they were each stabbed four times, and the fifth knife was a fatal wound. That is to say, they were still broken in the fifth round. balance.

The longer the persistence, the greater the chance of being rescued... But they still died under the knife in the end, maybe their relationship broke down, maybe they couldn't bear the pain, couldn't bear the despair, and chose to give up.The truth is estimated that only the robbers know.

Human nature cannot stand the test.

The same is true when facing loved ones.

Those panicked victims would not think that the answer is the opposite of the final fact. Under high pressure, people will think more about the actual results and will not dare to gamble their lives.

But to die is to live, to live is to die.

The family being tested must be as strong as gold, and everyone has the idea of ​​breaking the boat, so that it is possible to persevere in the end and gain the hope of life.

Su Hui added: "There are too few testimonies that the police can access, so they can only make judgments based on many scenes."

Lu Junchi said: "In any case, we are now closer to the answer than before. Although your analysis is on the psychological level, I think that if we continue to investigate from these directions, we can find empirical evidence."

Those brutal murderers are no longer a vague phantom, they have now been outlined by Su Hui.

The General Bureau finally arrived. Lu Junchi's car was parked outside the gate of the Huadu General Bureau. Su Hui got out of the car and sat on his waist, even with a waist support, he still felt tired from the journey.

Lu Junchi walked in front, and Su Hui followed him. The two walked through the front hall of Huadu General Bureau, walked all the way to the back office area, and went up to the serious crime team on the third floor.

Several team members in the group were not idle, seeing Lu Junchi come in and called out to Team Lu.

Lu Junchi told a few people about their investigation today, and Su Hui told the psychological portrait of the criminal he drew, so that all team members had a deeper understanding of the murderer.

Then Lu Junchi asked them: "How is your work progressing?"

Qu Ming said: "I have transferred all the domestic fire accident files in the past three years, and then Zheng Bai and I are investigating one by one. There are already three suspects. I will sort out the list later after the investigation."

Lu Junchi said: "Okay, if you have any news, please report to me at any time."

Xia Mingxi: "Team Lu, I'm conducting victim analysis here. I have obtained all the information of the victims in several cases, looking for commonalities between them."

Lu Junchi nodded: "Everyone continue."

Then it was all kinds of summary information, signing, sorting out materials, and I was busy until I got off work in the afternoon.

Su Hui lay on the table, admiring Lu Junchi's vigor. They got up before six o'clock in the morning, and then ran all the way. He was still tired after sleeping in the car for a long time. I'm afraid there is only Lu Junchi who is "inhuman" "Still able to keep working like this.

In the evening, Lu Junchi drove the car back to Su Hui's community. Su Hui looked at the elevator, and there were four words "repair outage" written on it.There is a notice posted by the property next to it, and it will be out of service until [-] pm.

After a busy day, Su went back to Fue, and completely collapsed. He regretted it so much that he bought his house on the tenth floor.

Lu Junchi held him back and said, "Let's go, just take it as a workout."

In order to lead by example, Lu Junchi took the lead in climbing the stairs and walked in front.

Su Hui was able to follow at first, but then he lost his strength and gradually fell behind.

Lu Junchi suggested once to take him away.

Su Hui waved his hand: "You go up first, don't worry about me."

When he reached the seventh floor, there were 24 steps on each floor. Su Hui counted them clearly, but his brain was starved of oxygen, his limbs were sore, and his legs seemed to be filled with lead, and he couldn't move.

Su Hui rested for a while with his cane on his back, and looked up. The endless stairs spread upwards like a spiral. Su Hui felt his surroundings spinning for a moment, everything was twisting, and the corridor seemed to have become It's soft and will collapse when you push it hard.

He didn't dare to look up again, the sense of unreality deepened further, Su Hui leaned on the wall to keep his body from falling, as if there was an endless abyss behind him.

He felt short of breath. The air seemed to be mixed with ice blades, forcing him to cough. The cough came from the inside out, as if the lungs had lost their normal breathing function.

"Su Hui." Suddenly a voice rang in his ear. Su Hui raised his head and couldn't see the person clearly, but judging from the voice, it should be Lu Junchi.Counting the time, he should have climbed to this meeting long ago, but for some reason he left and returned.

In fact, Lu Junchi never walked too fast. He climbed one floor more than Su Hui, and looked back at him from time to time. When he reached the sixth floor, he found that Su Hui suddenly stopped. Hui's state was a bit wrong, his eyes were out of focus, his face turned pale, and he kept coughing.

Su Hui managed to catch his breath and stopped coughing. He felt a little strange around him, but it was much better than before. He and Lu Junchi explained: "I'm just a little tired, let me rest for a while."

"I know you're tired today." Lu Junchi saw that Su Hui didn't seem to be okay at all, but he was still stubborn. He stopped him and said, "There are still a few floors left. I can carry you up."

Su Hui became a little nervous, covered his mouth and coughed a few more times: "No, no need, I'll rest for a while, it'll be fine later, don't make such a fuss."

Lu Junchi knew that he was used to this kind of work rhythm, but it was too much for Su Hui.Instead of saying that he is protecting him now, it is better to say that Su Hui is doing his best to help the crime team.Thinking of this, his heart softened, and he replied to Su: "Now there is no one else here, no one will know, and I will only recite this once."

Su Hui looked at him, and took a few seconds to understand what Lu Junchi was talking about. He tilted his head, as if hesitating.

Lu Junchi said again: "If you go up as soon as possible, you can have a good rest."

Su Hui was moved, he hesitated for a moment, no longer stubborn, and handed his scepter to Lu Junchi.

When Lu Junchi turned around, he put his hands on Lu Junchi's shoulders and leaned on Lu Junchi's back.

Completely different from Su Hui, Lu Junchi definitely has the kind of body that looks thin when he wears clothes and takes off his clothes. He is tall, keeps exercising, and has perfect muscle lines, like a natural clothes hanger.His shoulders are so broad, but he feels a sense of security when he leans on them.

Su Hui closed his eyes, not relying on his eyes, but only relying on his senses to experience the world.

He could feel the temperature of Lu Junchi's body and touch the muscle lines around his neck. With his strides, his body moved lightly, and the feeling of levitation surrounding him gradually faded away.

Su recalled that after this period of time, his moon puzzle was almost finished.The black and white fragments are constantly closing under his fingertips to form a complete graphic, which is the shocking feeling brought by the universe and the planet.

In the dark, it seems that his world is more complete.
