In the conference room of the Huadu General Bureau, Lu Junchi withdrew his gaze and continued: "The various details of the Xisha case are already here. Today, everyone must work overtime to read all the previous files of this case and fully understand the case."
When he said this, he paused for a while and said, "It's still a while before I get off work in the afternoon, Xia Mingxi, you will summarize the data, Zheng Bo, you and Qiao Ze will go to the crime scene and have a look, Qu Ming, you will go and hand over to the various groups. , to understand everything clearly. The people in the Xing team are also available for us to dispatch, and you bring Shao Lin with you."
Several team members nodded, Lu Junchi's work assignment has always been reasonable and clear.
There are several steps in the general case-solving process. First, investigate the crime scene, understand the crime process, and restore the scene to the greatest extent possible. Second, determine the tools for committing the crime, search for various witnesses and material evidence, and third, lock the suspects of the criminals and conduct interrogation and interrogation.
In these processes, it is also necessary to continue to reason, search, and find the motive for the crime.
Lu Junchi added: "Also, hurry up, everyone, go back and clean up today. From tomorrow, the hotel next to the headquarters will open a room, which can be used for temporary rest."
The others went out first, and Xia Mingxi also held a stack of past files to organize and archive.
Suddenly, Lu Junchi and Su Hui were left in the conference room.
Lu Junchi faced Su Hui and said, "Su Hui, this case..."
Su Hui seemed to know what he wanted to say, and interrupted him: "You don't have to worry about me, where I fall, where will I get up. I know some details of this case, but it is more suitable for handling than others. Moreover, I I hope I can catch the murderer myself." Otherwise, he wouldn't take the initiative to send text messages to Lu Junchi, hoping he would follow up.
In the past case of Xisha, both of them had read the archives many times, and even the written records on those archives were not known in detail by Su Hui, a witness.
Lu Junchi said solemnly: "I found that the delivery method this time is completely different from the previous delivery method."
Su Hui nodded and said: "I also found this. I think this case is too different from the past case of Xisha, and there are too many similarities. The case of Xisha has always been strange and unconventional... "
Whether it was two years ago or two years later, there must be a part of the truth about this case that they haven't touched.
Su Hui blinked his eyelashes and made a judgment: "About this case, in the past reasoning process, I may have some misunderstandings. In order to avoid misleading you, I hope that this investigation can be based on your thinking. leading."
He has experienced the fine sand case. People always have habitual thinking and preconceived ideas, and they will enter the maze because of this. Lu Junchi has just come into contact with this case, and he may bring new ideas to solve the problem.
Lu Jun said lately: "I have some ideas now, and I feel that I should start with this case."
After all, the Xisha case is old, and time will destroy a lot of evidence, but the new case is different, they can find more information.
Su Hui nodded: "Okay."
The two quickly worked out the direction and basic plan for the investigation.
As the case has been going on for several hours, there are some video photos of the scene, video footage and statements from the uninjured.
Compared with Su Hui, whose eyesight is a little difficult, Lu Junchi can see faster.
He browsed it and replied to Su, "I found that these two cases have one thing in common."
Su Hui raised his head: "What?"
Lu Junchi said: "In the two bus explosions, it was after a dispute between passengers." He looked through the confessions and compared them, "And both times, female passengers were harassed."
In the previous investigation, Xing Yunhai had recorded the statements of the whole car, and the bomb was discovered about ten minutes after the passengers quarreled, when the man was still in the car.
Because the first explosion didn't actually happen, they couldn't directly link the explosion to this event.
But if this happens twice, the meaning is completely different.
Lu Junchi compared the list of passengers on the two buses in his hand, and confirmed that the same person was arguing: "It was the deceased Duan Siyuan who was molesting on the bus, and he also appeared on the last bus. "
After he finished speaking, he pointed the same name on the list to Su Hui. Then Lu Junchi sent the information to Qiao Ze and asked him to check further.
"Two buses with different routes and different times, but the same person appeared. This person is still one of the dead. It is very likely that he was the target." Su Hui squinted and read the two confessions, "There is another common The point is that when the female passenger had an argument with this person, the passengers were indifferent and the matter was settled, which may also be one of the conditions for the incident."
Lu Junchi nodded seriously: "Then let's follow this person and see if we can investigate."
The information on the deceased was quickly passed on.
Duan Siyuan is 44 years old this year, 1.72 meters tall, with dark skin and a little thin.
Judging from the photo, his eyes were dull and cloudy.
If you can go directly to his thinking, you can find that he is thinking about those things almost all the time...
His whole life was swallowed up by that incident.
Desire, endless desire, he became a slave to the body.
The man, who was one of the dead in the accident, also had an argument with a female passenger before the accident, which caused the female passenger to get out of the car in a hurry.
Lu Jun looked at the information for a while and said, "This man is really disgusting."
The first part of the video has been completely preserved. Duan Siyuan almost chased after the girl. With the help of the crowd and the arrangement of the seats in the car, he forced the girl into a blind spot. He was frightened, but he had no regrets.
It was this person who finally died in an explosion on the bus. Judging from the photos of the corpse, there was no whole corpse.
Su Hui looked at Duan Siyuan's background introduction.
There are three siblings in Duan Siyuan's family. He is the oldest and the youngest in the family. He has been spoiled by his parents since he was a child.
When Duan Siyuan became an adult, there were several demolished houses in his family. In addition to living in his own house, he could also collect rent. This person did not go to work well, and he was idle every day.
After his parents died, his sisters didn't marry him, and he kept wandering in those cars, buses, and subways. Even spending more time in those vehicles than at home.
This is a culpable habitual offender whose initial report was made eighteen years ago.
However, he has problems with intelligence and is very arrogant, and many people avoid him.
The elder sister in the family brought him a mental certificate, saying that his younger brother was mentally ill, and that what he committed was not a big deal, and he has never been sanctioned.
Lu Junchi read the testimony of the witnesses, and patiently called Duan Siyuan's two sisters. They were not sad about the death of their family members, but felt relieved, and kept saying that they would cooperate with the police's work.
Lu Junchi asked Su Hui: "Is it possible that the suspect who planted the bomb this time is a woman?" He thought that if a woman was hurt by Duan Siyuan's behavior, she might take revenge.
Su Hui lowered his head and said, "A man who seeks revenge for his girlfriend or wife cannot be ruled out. However, if the target is really Duan Siyuan, this person may be weak and vulnerable."
Lu Junchi entered the system, checked it, and concluded: "I made statistics. In our system, there are 43 alarm records about Duan Siyuan."
However, in these 43 police reports, he was not dealt with in the end, either a settlement was reached or nothing was left.
Su Hui said indifferently: "There are far more victims. Most of them should not have called the police."
He found some of his accounts through Duan Siyuan's associated mobile phone number, and even took some photos of the bottom of his skirts and posted them publicly on the Internet.
And it seems that although this person is middle-aged, his desire is not diminished, the frequency of posting is very high, and the activities are also very frequent.
Su Hui supported his chin with his hand and concluded: "He is an unemployed vagabond. He wakes up every day and eats lunch in front of his house. He gets in the car and follows the car to sit anywhere. On an average day, there will be at least two or three victims."
In other words, there may be nearly 1,000 victims in one year, and in ten years, this is a figure of tens of thousands.
After all, only a few people choose to call the police.
And Duan Siyuan's behavior may cause those women to suffer substantial harm, make them feel uncomfortable, cry, and even have nightmares, and cause fear of men, and they will not be able to get out of it for many years.
This kind of thing is terrible and sad, and there are more than one or two men like Duan Siyuan in this city.
There is no way to effectively curb this situation.
When Lu Junchi heard this, there was anger in his eyebrows: "What's the difference between a man who can't control his lower body like this and an animal..."
Su Hui nodded in agreement: "I should have been castrated long ago."
Lu Jun returned late and finished all the situation, and sighed: "There are too many potential victims, and it is not easy to follow this line."
He originally thought that if he found out Duan Siyuan, he would be able to follow the clues, but now, he seems to have stepped into a maze.
An old hooligan who casts a wide net, there are many potential victims, and it is impossible to confirm who will be the suspect for a while.
"In the previous fine sand bombings, the people who died were random people. At that time, the murderer did not have this kind of 'justice' quality." Su Hui coughed a few times while covering his mouth, and asked him again, "Duan Siyuan How far is it from the location of the explosion?"
Lu Jun said lately: "One row. But the flow of people in the car is constantly changing. I'm not sure if he changed seats after the bomb was placed..."
It is not a pity for such a scum to die, but Duan Siyuan is only one of the dead.
He is suspected to be the target of the killer.
But the police have not been able to confirm whether he is the real target of the murderer, and can only use these as clues.
Su Hui pondered attentively, and now there are only two cases related to bus explosions.
It is only their speculation that the case is related to Duan Siyuan. Maybe the murderer just committed the crime randomly as usual, or maybe Duan Siyuan just happened to appear on these two buses.
After chasing here, this starting point is indeed not very good to continue.
The two studied until they got off work at night, and Lu Junchi closed the file: "Let's do it today, and I'll look at other records and on-site inspections at night. Tomorrow, there will be an EOD expert from the special police, who may be able to give us some clues."
Su Hui asked, "Do you have any other ideas?"
Now they have to race against time to get ahead of the killer.
Lu Jun said lately: "I want to study the sand scattered on the scene."
