Qu'an County started spending a lot of money on surveillance, equipment, and systems eight years ago. That is to say, it is not too late to make up for the mistakes.
In other words, when the station exploded eight years ago, they had very little surveillance.
It’s not that it’s not installed, it may not be used much.
The surveillance inside the station is barely usable, but after exiting the bus station, the location 30 meters away from the exit is a pure blind spot. In comparison, the surveillance in places such as small shops and supermarkets is more useful. But
It's also relatively speaking.
Qiu Yue and the others had also counted on the surveillance video, but they had lost hope, so they turned to other directions.
Liu Jinghui found a computer alone and asked the technician to play the videos he had compiled before, but naturally there was no result.
After struggling for more than an hour, Liu Jinghui was tired of watching, Qiu Yue was tired of standing, and only Jiang Yuan was still looking at the footprints.
Not only were there many footprints on site, but they were also of poor quality.
Even if it was a special team, the actual footprints that were collected that day were those stained with electrostatic methods, and there were only dozens of them.
The remaining footprints are all in the state of being photographed for evidence. This kind of footprints will not be looked at carefully by ordinary trace inspections - if you have to analyze it, take your time, otherwise, everyone should choose to be more comfortable.
Way of working……
When Jiang Yuan wanted to screen, he had to identify as many footprints as possible. This process was very difficult and cumbersome.
That is to say, Jiang Yuan had just obtained the lv5 footprint analysis, and he was very excited about doing the footprints.
Liu Jinghui's eyes were focused, thinking and worrying at the same time.
Jiang Yuan finally provided a new clue, but it couldn't be confirmed or ruled out, which made Liu Jinghui feel uncomfortable all over.
It doesn't matter if you follow a clue to the end and find it is a dead end, or the murderer cannot be found. But the interruption of the clue is the most difficult thing for criminal police officers to endure.
Liu Jinghui walked to the other end of the conference room and flipped through his notebook aimlessly.
Qiu Yue sat in front of him and soon felt bored. Looking at Liu Jinghui's expression again, he said, "May I say something?"
"You said it." Liu Jinghui quickly sat up straight. In the police force, people are more particular about respecting their elders, especially the previous generation of police officers, who were basically brought up through the master-apprentice system.
"You don't have to be so polite." Qiu Yue sighed and said, "I think you want to follow the footprint information found by Jiang Yuan. Which direction do you want to check? In fact, we made some lists back then, but we didn't put them in the list.
Go in the files, especially the less formal ones."
Liu Jinghui's eyes lit up when he heard this. Indeed, he wouldn't compile various lists and information as if he were making a report.
The final dossier is naturally the same as the report and must withstand scrutiny, but the process of solving the case does not need to be so rigorous. And if the case cannot be solved, the last thing submitted will naturally not be meticulous.
"Have you made a list from the perspective of the beneficiaries?" Liu Jinghui did not ask Qiu Yue how many lists they had, but directly asked what he wanted.
Qiu Yue nodded first, then thought about it: "The benefit theory, I must have considered it at the time, but what I originally considered was an explosion targeting unspecified groups of people... You should keep all the hard drives from back then, and search for 'SYZ'
'Folder, see if the information in it is still there?"
"Okay." Liu Jinghui called immediately. The explosion at Qu'an Station was a big one, and it was not settled smoothly that year. The file submitted was a file, the report was a report, and the remaining hard drives and notes were also sealed.
The county bureau can usually retain the projects that the provincial department has participated in for a longer period of time.
Soon, the hard drive containing the "SYZ" folder was delivered along with the hard drive box.
Liu Jinghui asked an IT person to come over and help him copy and organize it into his computer, then open it and read it carefully.
The so-called benefit theory is nothing new. To use a widely circulated saying, whoever benefits the most is the murderer.
But if it is an anti-social incident, such as an explosion targeting an unspecified number of people, the benefit theory is somewhat untenable.
Although the special team at that time also discussed and demonstrated the possibility of murder, this was not the main direction of investigation after all, and the list of beneficiaries was very rough.
Despite this, the special team eight years ago still compiled a list of over a hundred people.
Among them, there are private bus owners, shop owners and operators at the side entrance of the station, competitors of motorcycle shops, and station managers who have risen to the top because of this...
The list is very rough and not sorted, and it is not clear who has benefited the most. Fortunately, the information of the relevant people is very complete, including names, ID numbers, workplaces, reasons, etc., all clearly visible.
Liu Jinghui looked at it for a while, and stopped looking at the information behind it. He screened it by age first, and based on the information Jiang Yuan provided later, he took out the people who were 34 years old at the time and about 42 years old now.
After this selection, there were only two people on the entire list. Liu Jinghui called them separately and found that their heights did not match.
Frowning, Liu Jinghui waved over two more detectives and said, "Call the people on this list. The women will ask about the height of their husbands and ex-husbands. The young ones will ask about their fathers, and the old ones will ask.
Those who ask about their sons, men too, ask about their height, and those who ask about their fathers, brothers, and sons. Those who do business ask about the height of their partners, and make a list of men who are about 1.6 meters tall."
Liu Jinghui wanted to compare this table with the footprints provided by Jiang Yuan, so he simply asked about his height. No matter how his weight, age, and appearance changed, his height would never change.
The two detectives didn't ask any questions and started busy working.
Qiu Yue looked at the increasingly heated atmosphere, feeling peaceful and nostalgic. He just looked at Jiang Yuan's back, as if he was looking at the emperor's new clothes.
At this moment, Qiu Yue felt that he felt his true self: a simple young man who had not changed his original intention after many years of turmoil and still had the kindest ideals...
"Liu Chu, there's one over here." The detective sent a note,
"Hou Tianlong." Liu Jinghui glanced at Qiu Yue and said, "Do you have any impressions?"
"No, who is he?"
"I opened an auto repair shop 8 years ago, with a front shop and a back yard. My wife is in charge of the front and my husband is in charge of the mechanical repair part..." Liu Jinghui looked a little more serious. If he knows how to repair machines, he already has the basics of making bombs.
Qiu Yue has really recalled too many details about this case in the past few years. He frowned and thought for a while and said: "I remember that his auto repair shop is on the other side of the city, and the business itself is different from the victim.
Conflict. Why is he on the list?”
"His wife is on the list. His wife is a strong woman. She and the victim's motorcycle repair shop represent the same company's engine oil. They both want to be agents of Qu'an County. The two of them even met in front of someone from the engine oil manufacturer.
We had an argument in person." Liu Jinghui paused, looked at the computer screen, and said: "He is 1.6 meters tall. He was 34 years old eight years ago. He and his wife divorced four years ago. Now he is a relatively large engine oil agent in the county.
Already..."
As Liu Jinghui read, he shouted: "Old Han, come and see this man, please come and ask me."
"It's possible." Captain Han responded first. After reading the person's information, he felt his brain's nerves suddenly connected: "This person matches the relevant information of the suspect... I think we can do a side investigation first.
"
"Okay, I agree." Liu Jinghui said.
In the case of the case 8 years ago, all aspects of evidence were no longer effective. At this time, the greatest advantage of the police was that the enemy was overt and we were covert.
After not moving for such a long time, the murderer must have relaxed. Someone who has been nervous for 8 consecutive years should have been admitted to a mental hospital for anxiety.
Therefore, side investigation is most beneficial at this time.
