Criminal Investigation Files

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

Lu Siyu went directly to the bathroom of the police station. Just now he felt cold sweat pouring out of his forehead, and the breakfast he had in the morning was churning in his stomach. After entering the bathroom, I vomited all over, and my eyes were full of dots.

Lu Siyu knew that it was not that easy to quit the medicine. He could control his will and try not to take the medicine, but his body didn't think so at all. He tore it to pieces.

It felt 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.From the corner of his eye, 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 awake in an instant, straightened up, and only hoped that Xu Changying hadn't noticed his embarrassment just now, and then he thought that when he came in, the doors of the restroom were all open, no one was there at the time, Xu Changying Changying should have just come in not long ago.

Xu Changying didn't say anything, just took a few tissues from the table and handed them to him, without asking if he was feeling well.

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

The two walked to the corridor by the bathroom door, Xu Changying asked, "How did you think about the matter I asked you last time?"

Lu Siyu paused for a few seconds, trying to regain his composure: "The case here has just begun." The implication is that even if it is necessary to transfer the team, now is not the time.

Xu Changying chuckled, "Why? Without you, Song Wen wouldn't be able to handle this case?"

Hearing this, Lu Siyu suddenly got excited, saying that he can do whatever he wants, but he can't do anything about Song Wen. He couldn't help but want to defend Song Wen, "Then Team Xu may not underestimate Song Wen too much. team? He has the highest rate of solving crimes in the Nancheng Bureau."

"You have a good relationship with your captain."

Xu Changying chuckled: "But Song Wen, I took his case, Gu Ju asked him to hand it over, and he handed it over to his subordinates. I didn't see how much you, the captain, love this job. persistent."

Lu Siyu really wanted to say something, it's because you don't know him well, so he opened his mouth and said, "Captain Song just opened a case recently, so he's a bit busy."

"Oh, then I wish you guys solve the case as soon as possible." Xu Changying moved his fingers while speaking, he didn't confront Lu Siyu again, but his tone was tinged with contempt, as if Song Wen was just someone not worth mentioning Opponent, "A lot of people on my side are eager to come in, you'd better make a decision quickly."

Lu Siyu frowned slightly, and then he asked, "Captain Xu, why did you choose me?" The so-called excellence is just a superficial statement. Xu Changying is not easy to get along with, nor is he easy to fool. There are his so-called rules, and there must be his reasons and ideas for choosing him.

Xu Changying didn't evade this question, nor was he in a hurry to answer it. He asked him first, "Do you remember the first crime scene you saw?"

Scenes suddenly appeared in Lu Siyu's mind. It was there that he seemed to have died once. He forced himself to stand up straight, trying not to look abnormal: "Remember, I have never died in this life. Will never forget."

"Treasure this feeling, I can see that that case has touched you." Xu Changying explained, "I think every case has emotions, like a soul, it's not Superstition, whether it is the murderer or the deceased, there is a reason why things happen and why they end like this. A good criminal policeman is like a good actor. When facing a case, you have to enter the drama and put Immerse myself in it, there must be waves in my heart, I must transfer the hatred of the murderer to myself, and take it as my business to catch the murderer."

Xu Changying paused and said: "Many policemen, especially the old policemen who have been in the job for a long time, have lost this temperament. Being a policeman is just a job they depend on for a living. They hate evil like hatred? It doesn't exist. They have been numb for a long time, and I can tell the difference with just one look. I am not saying that those people are not good police officers, but that I look down on such people. In other words, I don’t need A person who clocks in at work and lives his own life after work. I need someone who is on the strings 24 hours a day, who can fight side by side and solve crimes with me.”

Hearing what he said, Lu Siyu seemed to have been hit in the dark for an instant. He thought he was hiding what was in his heart well, but for some reason Xu Changying pointed it out. Gradually tighten and knead into a ball in the palm of your hand.

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

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

Lu Siyu knew very well in his heart that he was not the type of person Xu Changying described. His behavior had a purpose. He was paying attention to the case, finding out the criminal's heart, and using this to vent his desire. Numb your nerves.

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

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

"One more thing, I heard that your mentor at the police academy was Wu Qing." Xu Changying looked at him and said, Song Cheng has always cared about this old partner, and Wu Qing does have something special about him. place.Before Song Cheng mentioned Wu Qing, Xu Changying had never heard that Song Cheng had such a high opinion of people. He was curious about Wu Qing, and by the way, he also paid attention to Lu Siyu.

When the two of them said this, someone happened to come from the corridor. Lu Siyu didn't want to entangle Xu Changying any more, so he lowered his head and said in a low voice, "I see. I'll answer you after I think about it. Thank you, Team Xu."

When Lu Siyu returned to the forensic room, everyone in the team was there, but Lin Xiuran was called away.Song Wen glanced at him through the crowd, as if he wanted to ask why he had been away for so long.Lu Siyu picked up the notebook and lowered his head, deliberately avoiding his gaze.His hands were still trembling a little, his throat was burning with pain, his body was a little weak, and his stomach was empty, but the discomfort was not unbearable.He drank some hot water and bit his nails habitually.

At this time, Zhu Xiao's notebook made a light beep, and the results in the system were just settled, and everyone's eyes were attracted to them.The progress bar has become [-]%, but the matching item is empty.Zhu Xiao was a little discouraged, and raised his head to report truthfully to Song Wen: "Team Song, no one was found."

Lao Jia heaved a sigh of relief, covered his chest with a painful expression, and said, "We tried our best, it seems that that brother is really not from our Nancheng..."

"Why do I hear your tone of liberation?" Fu Linjiang mercilessly exposed him, "Or should we change our thinking? Should we expand the scope and ask the province?"

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

The limit Zhu Xiao made before was a bit too detailed. If there were some mistakes in it, the results would not be screened out. This time, the limit became wider, and the calculation speed of the system was much faster. After a while, a person's name popped up.

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

Zhu Xiao also said: "What did I say, look at this big data system, it really is unreliable..."

Lao Jia looked at the result, but became serious: "Oh, that's right, it might be this person. Have you ever heard of that word—"Borrowing a dead body back to life"?"

Zhu Xiao thought he was going to say something, and showed contempt on his face: "Feudal superstition, what age is it?"

Old Jia said: "I'm not talking nonsense. Have you heard the stories told by the old people? Borrowing a dead body to return to life means that this person still has something to do in his heart. He borrowed someone else's body and returned to the world to repay his kindness or revenge. Forget it, we won’t leave until the mortal relationship is over.”

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

Song Wen ignored them and clicked on the record, "Chen Yanqiu, male, 26 years old, height 181, blood type A, frequently used mobile phone number... frequently used mailbox... ID number... education... school... bank card under account ...real estate under his name...resident address...diagnosed with cancer two years ago, had gallbladder removal surgery a year ago...cause of death: death, date of death...date of cremation..." As he moved the mouse with his fingers Down, a photo appears.

Although this big data system is a bit slow to query, the information collected is fairly complete. As long as it is the information that the police can collect, almost all of it is presented.All kinds of files, experience, even the date of ticket purchase, bank card expenditure, all data are available.This saves most of the investigation time.The living people were compressed in this way, recorded concisely on the Internet, and compressed into paragraphs 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 have imagined that they would leave so many clues and traces.

Fortunately, such a system is used by the police. Every time a search is performed, the key must be entered. If it is in the hands of others, all relevant information can be found. This result is a bit scary.

Lu Siyu walked behind several people, looked at the detailed information listed, and said softly, "It should be this person."

Fu Linjiang still couldn't believe it: "Ah, Xiao Lu, this man died a long time ago."

"It shouldn't be him who died before, but this corpse." 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 are very consistent, the probability of this is very low." After talking too much, his throat hurt a little, and he coughed lightly.

Song Wen also said: "From the profile picture, it looks very similar. It can be seen from the photo of his ID card that he has a canine tooth on one side." Having said that, he looked at the mummy lying on the side. ID photo is exactly the same.

Human teeth can affect the entire facial features, and forensic doctors often determine the identity of the deceased through the characteristics of teeth and dental models.Song Wen, who often draws portraits, discovered this point even more keenly.

"But this is a person who died seven months ago. He was also issued a certificate to be cremated in a crematorium. Is it really like what Lao Jia said, someone 'borrowed a dead body'?" Fu Linjiang pointed to the screen and said.

"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 there is something wrong with the so-called 'impossible'." His gaze Turning to the mummy on display, "That is, the person who died seven months ago was not him. He borrowed someone else's 'corpse' and returned his own 'soul'."
