Criminal Investigation Notes

Before he finished speaking, Lu Siyu put down his notebook and walked out first. Song Wengang wanted to call him, but Lin Xiuran held him back.

Lu Siyu went directly to the bathroom of the police station. Just now, he felt the cold sweat on his forehead keep coming out. The breakfast he had eaten in the morning was churning in his stomach, just as if he had two hands twisting the soft internal organs. I vomited after a while after entering the bathroom, and my eyes were full of dots.

Lu Siyu has long known that it is not so easy to quit the medicine. He can control his will and try hard not to take medicine, but his body does not think so at all. All the organs are united to rebel against him, clamoring He tore it to pieces.

It feels better to spit it out. Lu Siyu rested in the cubicle for a while and felt much better. After coming out of the cubicle, he went to the sink and rinsed his mouth with water.In his peripheral vision, he seemed to see someone on the other side of the pool. Lu Siyu raised his eyes and saw that the person was Xu Changying from the provincial bureau.

Lu Siyu was half sober in an instant, and straightened up, hoping that Xu Changying hadn't noticed his embarrassment just now, and then he thought that when he came in, several of the toilet doors were open. No one was there at that time, Xu Long Ying should have just entered.

Xu Changying didn't speak, took a few tissues from the table and handed it to him without asking him if he was unwell.

Lu Siyu took over and covered his mouth, wiped the water stains on the corner of his mouth, and coughed lightly, "Thank you Team Xu."

The two walked to the corridor at the entrance of the bathroom, and Xu Changying asked, "How did you think about the matter I asked you last time?"

Lu Siyu paused for a few seconds, trying to calm himself: "The case here has just begun." The implication was that even if it is necessary to adjust the team, now is not the time.

Xu Changying chuckled lightly: "What? Song Wen can't handle this case without you?"

After hearing this, Lu Siyu suddenly came up, saying that he can do anything, but Song Wen can’t. He couldn’t help but want to protect Song Wen. "The Xu team may not underestimate Song Wen. Are you on the team? He has the highest rate of solving cases in Nancheng City Bureau."

"You have a good relationship with your captain."

Xu Changying chuckled: "But Song Wen, I took his case, and the Bureau asked him to hand it over, and he gave it all to his subordinates. I didn't see how much you, the captain, is responsible for this job. Perseverance."

Lu Siyu wanted to say something, that is because you didn't understand him, so he opened his mouth and changed his sentence: "Team Song has just opened a case recently, and it's a bit busy."

"Oh, then I hope you can solve the case as soon as possible." Xu Changying moved his fingers while speaking. He didn't face Lu Siyu again, but his tone was slightly contemptuous, as if Song Wen was just not worth mentioning. Opponent, "Many people on my side are eager to come in, you'd better make a decision quickly."

Lu Siyu frowned slightly, and then he asked: "Team Xu, why did you choose me?" What the so-called excellent is all superficial. Xu Changying is not a good person to get along with, nor is he a fool. He acts. There are his so-called rules, and to choose him, there must be his reasons and ideas.

Xu Changying did not evade this question, nor was he eager to answer. First he asked him back: "Do you remember the first crime scene you saw?"

Scenes suddenly appeared in Lu Siyu’s mind. It was there. He seemed to have died once. He forced himself to stand upright and resisted to look abnormal: "Remember, my life I will never forget."

"Cherish this feeling well, I can see that that case touched you a little bit." Xu Changying explained, "I think every case has emotions, just like a soul. This is not true. Superstition, the murderer or the deceased, there are reasons why things happen and the ending is like this. A good criminal is like a good actor. In the face of a case, you have to enter the scene. I am immersed in it, there must be waves in my heart, and I must transfer the hatred of the murderer to myself, and treat the murderer as my own business."

Xu Changying paused and said, "Many police officers, especially the old policemen who have been working for a long time, don't have this kind of temperament in their bodies. Being a policeman is just a job they rely on for their lives, hatred and hatred? Nothing exists. They have long been numb, and I can tell the look in their eyes. I am not saying that these people are not good policemen, but such people, which I look down on. In other words, I don’t need to A person who clocks in at work and leads his own life after work. I need someone who is tight on the strings for twenty-four hours, who can fight side by side and solve crimes with me."

Hearing what he said, Lu Siyu seemed to have been spotted in an instant. He thought he had hidden the things in his heart very well, but he didn't know why Xu Changying pointed it out. After seeing the clue, he held the hand of the tissue. Gradually tighten it and knead it in the palm of your hand.

Xu Changying felt something sensitively and raised his head and asked, "Why, you don't agree with what I said?"

"Xu Team's thinking is too harsh. Even if it is a policeman, each of us is not a machine to solve crimes, but humans." Lu Siyu blinked, avoiding Xu Changying's sight and said: "And when it comes to hateful hatred Many people in this police station are much better than me..." For example, Song Wen.

Lu Siyu is very clear in his heart that he is not the type of person Xu Changying described. His behavior is purposeful. He is paying attention to the case, exploring the heart of the criminal, and venting his desires. Paralyze own nerves.

Xu Changying sensitively discovered his unwillingness, but misjudged this situation as his sense of justice.

Under this situation, Lu Siyu felt more and more that entering Xu Changying's team might not be a good choice, but after all, this was a shortcut for him to understand the truth of the year, and he was a little hesitant for a while.

"One more thing, I heard that your instructor was Wu Qing when you were in the police academy." Xu Changying looked at him and said, Song Cheng has always remembered this old partner, and Wu Qing does have his special Place.Before Song Cheng mentioned Wu Qing, Xu Changying had never heard Song Cheng's evaluation of people so high. He was curious about Wu Qing, and by the way, he also paid attention to Lu Siyu.

When the two people talked about this, someone happened to come over from the corridor. Lu Siyu didn't want to entangle Xu Changying any more, and lowered his head and said in a low voice, "I see. I will answer you after thinking about it. Thank you Team Xu."

When Lu Siyu returned to the forensic room, everyone in the group was there, but Lin Xiuran was called away.Song Wen glanced at him through the crowd, and seemed to want to ask him why he had been there for so long.Lu Siyu picked up the notebook and lowered his head, deliberately avoiding his gaze.His hands still tremble, his throat hurts fiercely, his body is a little weak, and his stomach is empty, but the discomfort is not intolerable.He drank some hot water, then bit his nails habitually.

At this time, Zhu Xiao's notebook made a soft beep, and the results in the system had just been calculated, and everyone's eyes were attracted.The progress bar became 100%, but the matching items were empty.Zhu Xiao was a little discouraged and raised his head to report truthfully to Song Wen: "Team Song, no relevant people were found."

Old Jia breathed a sigh of relief and covered his chest with a sad expression: "We tried our best. It seems that Xiongtai is not our Nancheng..."

"Why do I listen to your liberating tone?" Fu Linjiang pierced him relentlessly, "Or let's change our thinking? Should we expand the scope and ask about the province?"

"Wait, modify the screening rules." Song Wen frowned and thought for a moment, changed a few keywords, and pressed the Enter key again.

The limitation made by Zhu Xiao before was a bit too detailed. In case there are some mistakes, the results will not be filtered out. This time, the limitation becomes wider and the calculation speed of the system is much faster. Not long after, a person's name pops up.

"There is a related one!" But then, Fu Linjiang looked at the information and sighed, "Oh, this is a dead person. Seven months ago, Song Wen, did you forget to choose the survival option?"

Zhu Xiao also said: "What am I talking about, look at this big data system, it really is not reliable..."

Lao Jia looked at the result, but became serious: "Oh, yes, it may be this person. Have you ever heard of the word-'borrow a corpse to resurrect'?"

Zhu Xiao thought he was going to say something, showing a look of contempt: "Feudal superstition, what age is it."

Old Jia said: "I'm not talking nonsense. Have you ever heard the stories told by the old people? Borrowing a corpse to return to the soul, that is, this person has something to do in his heart, borrowing someone else's body, and returning to the world, to retaliate or revenge Not to mention, I will leave when the fate is over."

Zhu Xiao couldn't help reminding him: "Brother Jia, you are a policeman! You are a criminal policeman!"

Song Wen ignored them and clicked on the record, "Chen Yanqiu, male, 26 years old, height 181, blood type A, commonly used mobile phone number...common email address...ID number...education...school...account bank card ...The real estate under his name...the permanent address...the cancer was diagnosed two years ago, and the gallbladder was removed a year ago...causes of death: death, date of death...date of cremation..." With his finger moving the mouse Down, a photo appears.

Although this big data system is a bit slow to query, the information collected is quite complete. As long as the information can be collected by the police, almost all of it is presented.All kinds of files, experiences, even the date of ticket purchase, bank card expenditure, all the data are everything.This saves most of the investigation time.Those living people were compressed in this way, recorded concisely on the Internet, and compressed into segments of numbers and words.

The core development concept of police big data is to bundle and correlate various intricate data so that relevant information can be presented more three-dimensionally.

In life, people would never think that they would leave so many clues and traces.

Fortunately, such a system is used by the police, and the key must be entered for every search. If it is in the hands of other people, all relevant information can be found. This result is a bit scary to imagine.

Lu Siyu walked behind a few people, looked at the detailed information that was listed, and whispered, "It should be this person."

Fu Linjiang was still a little unbelievable: "Ah, Xiao Lu, this man is already dead."

"It shouldn't be him who died before. This corpse is the one." Lu Siyu analyzed from the side. "From the data point of view, all the information about this person is exactly the same as what we have now. Gender, age, height. , Blood type, and even disease and surgery conditions are very consistent. This probability is very low." After talking a lot, his throat was a little sore and he coughed slightly.

Song Wen also said: "From the head portrait, it looks very similar. It can be seen from the photo of his ID card that there is a single-sided tiger tooth." At this point, he looked at the mummy lying on the side, the teeth arranged and The ID photo is exactly the same.

Human teeth affect the entire facial features. Forensic doctors often use the characteristics of teeth and dental models to determine the identity of the deceased.Song Wen, who often draws portraits, discovered this more keenly.

"But this is a dead person seven months ago. I was also issued a certificate to go to the crematorium for cremation. Is it really like what Lao Jia said, someone'resurrected the soul'?" Fu Linjiang pointed to the screen.

"So, it's really possible." Song Wen stood up with a serious expression, "If all the possibilities are blocked, then you have to think about whether the so-called'impossibility' has gone wrong." His gaze Turning to the mummy displayed aside, "That is, the man who died seven months ago was not him. He borrowed someone else's corpse and returned his own soul."
