Qu'an County invested a lot of money in monitoring, buying equipment, and developing the system. It started eight years ago, that is, it is not too late to make up for it.

In other words, when they bombed the station eight years ago, there was very little surveillance.

It's not that it's not installed, it may not be used much.

The monitoring in the station is barely usable, but when you leave the bus station, the position 30 meters away from the exit is a pure blind spot.In contrast, monitoring in places like small shops and small supermarkets is a little more useful.But it is also relative.

Qiu Yue and the others had also counted on the surveillance video, but they had no hope, so they turned to other directions.

Liu Jinghui found a computer alone and asked the technician to play the videos he had sorted out before, but naturally there was no result.

After tossing and tossing for more than an hour, Liu Jinghui was tired of watching, Qiu Yue was also tired of standing, only Jiang Yuan was still looking at the footprints.

There are not only many footprints on site, but also poor quality.

Even if it is the task force, the footprints that were actually taken that day, that is, the footprints made by electrostatic method, are only a few dozen.

The remaining footprints are all in the state of taking pictures for evidence.This kind of footprints, ordinary trace inspection will not look at it carefully - if you have to analyze it, then spend some time, otherwise, everyone should choose a more comfortable working method...

Jiang Yuan had to screen, but he had to identify as many footprints as possible. This process was very difficult and cumbersome.

That is to say, just got the footprint analysis of lv5, Jiang Yuan is fresh and excited about doing the footprints.

Liu Jinghui focused his eyes, thinking and worrying at the same time.

Jiang Yuan managed to provide a new clue, which could not be confirmed or ruled out, which made Liu Jinghui feel uncomfortable.

It doesn't matter if a clue is followed to the end and it turns out to be a dead end or the murderer can't be found.But the interruption of clues is the most unbearable thing for the criminal police.

Liu Jinghui walked to the other end of the conference room, flipping through his notebook aimlessly.

Sitting in front of him, Qiu Yue soon became bored, looked at Liu Jinghui's expression again, and said, "Shall I say something?"

"Tell me." Liu Jinghui quickly sat up straight. In the police force, there is still a lot of respect for the elderly, especially the policemen of the previous generation, who were basically brought out by the master-apprentice system.

"You don't have to be so polite." Qiu Yue sighed, and said, "I think you want to search down the footprint information that Jiang Yuan was looking for. Which aspect do you want to search? Actually, we made some lists back then, but we didn't put them in the list. Go in the dossier, especially if it's less formal."

Liu Jinghui's eyes lit up when he heard it. Indeed, he would not compile various lists and materials like a report when he was working on a case.

The dossier that was handed in at the end was naturally just like making a report, and it had to withstand scrutiny, but in the process of solving the case, it naturally didn't have to be so rigorous.And if the case cannot be solved, it is naturally impossible for the final submission to be detailed.

"Have you made a list from the perspective of the beneficiaries?" Liu Jinghui didn't ask Qiu Yue how many lists they had, but asked what he wanted.

Qiu Yue nodded first, and then thought about it: "The theory of benefit, I must have considered it at the time, but at the beginning, I was thinking about the bombing case targeting an unspecified group of people... You guys put away all the hard drives back then, you can search 'SYZ ' folder, see if the information inside is still there?"

"Okay." Liu Jinghui called immediately.The Qu’an station bombing case was a major case, and it was not successfully closed that year. The files submitted were files, the reports were reports, and the remaining hard drives and notes were also sealed.

This kind of case that the provincial department has participated in, the county bureau can usually keep it for a long time.

Soon, the hard disk containing the "SYZ" folder was delivered together with the hard disk box.

Liu Jinghui asked an IT person to come over and help copy and organize it into his computer, and then opened it for careful reading.

The so-called benefit theory is nothing new.To use the widely circulated saying, whoever benefits the most is the murderer.

But if it is an anti-social case, such as a bombing case targeting an unspecified number of people, the benefit theory is a bit untenable.

Although it is said that the task force discussed and demonstrated the possibility of the murder, this was not the main direction of investigation after all, and the list of beneficiaries was very rough.

Even so, the task force eight years ago 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 been promoted because of this...

The list is very rough and not sorted, and it is not clear who is the one who has benefited the most.Fortunately, the information of the relevant persons is fully recorded, name, ID number, work unit, reason, etc., are all clearly visible.

Liu Jinghui looked at it for a while, and stopped looking at the information behind. First, he screened it according to age. According to the information provided by Jiang Yuan later, he took out the people who were 34 years old at the time and are now about 42 years old.

In this way, there were only two people in the entire list. Liu Jinghui called each of them and found that their heights did not match.

Frowning, Liu Jinghui beckoned to two criminal policemen again, saying: "You call the people on this list, and the women will ask the height of their husbands and the height of their ex-husbands. The young ones will ask their fathers, and the old ones will ask Those who ask about their sons, men also ask about their heights, those about their fathers, brothers, and their sons. Those who do business ask about their partners’ heights, and make a list of men with a height of about 1.6 meters.”

Liu Jinghui wanted to compare this watch with the footprints provided by Jiang Yuan, so he simply asked about his height.No matter how your weight, age and appearance change, your height will never change.

The two criminal policemen began to operate in a hurry without asking any further questions.

Looking at the increasingly warm atmosphere, Qiu Yue felt safe and nostalgic, but 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, after years of turmoil, his original intentions have not changed, and he still has the kindest ideals...

"Liu Chu, there's one over here." The criminal police sent a note,
"Hou Tianlong." Liu Jinghui glanced at Qiu Yue and said, "Do you have any impression?"

"No, who is it?"

"I opened a car repair shop 8 years ago. The front of the shop is in the back. My wife is in charge of the front, and my husband is in charge of the machine repair..." Liu Jinghui looked a little more seriously. If he knows machine repair, he has the foundation to make 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 does not conflict with the victim's business." .Why is he on the list?"

"His wife is on the list. His wife is a strong woman, and the motorcycle repair shop of the victim is the agent of the same motor oil. They both want to be the agent of Qu'an County. I have had an argument with you before." Liu Jinghui paused, looked at the computer screen, and said, "Height is 1.6 meters, 8 years ago, he was 34 years old, and he divorced his wife four years ago, and now he is a relatively large engine oil agent in the county. ..."

While reading, Liu Jinghui shouted: "Old Han, come and see this man, please come and ask."

"It can be done." Team Captain Han agreed first, and after reading the information on this person, he felt that his brain was connected all of a sudden: "This person matches the relevant information of the suspect... I think we can conduct a side investigation first. "

"Yes, I agree." Liu Jinghui said.

In the case of 8 years ago, the effectiveness of all aspects of evidence is no longer valid.At this time, the biggest advantage of the police lies in the fact that the enemy is clear and we are dark.

After such a long period of inactivity, the murderer must have relaxed. People who have been nervous for 8 consecutive years should have been sent to a mental hospital for anxiety.

Therefore, side investigation is the most beneficial at this time.
