Chapter 457: Standing for a Long Time

"Qiu Yue is here." Captain Han came to Liu Jinghui and asked in a low voice: "He wants to come and see our case. Are you familiar with him?"

"Qiu Yue?" Liu Jinghui was stunned for a moment, smiled, and said: "When I entered the industry, Director Qiu was already a big shot in the provincial department, and there was no chance to meet him."

That means he was not familiar with him.

Captain Han understood. He was working with Qiu Yue 8 years ago, and in his impression, Qiu Yue was somewhat domineering at that time.

Of course, powerful people are qualified to be domineering, especially those who can save time, increase income, and reduce risks for everyone. Normal people have a high tolerance.

But Qiu Yue eventually failed. Captain Han couldn't help asking: "I haven't heard much about Director Qiu since then. What did he do?"

Liu Jinghui answered the question irrelevantly: "It takes energy to solve the case."

Captain Han's expression changed: "Not really."

He also experienced this case throughout the whole process. Although he was very upset and regretful that he didn't solve the case, he didn't lose his energy. On the contrary, he has the courage to work hard after knowing shame.

Liu Jinghui shook his head: "Qiu Yue is already 50 this year. The explosion at Qu'an Station took several months, costly and had a huge impact. Many people in the office also said some unpleasant things. Director Qiu was also praised all the way, how could he bear this."

Captain Han clicked his tongue twice: "You can't stand being scolded?"

Liu Jinghui smiled: "As criminal police, what else can we have except fame?"

Captain Han was speechless immediately.

To be honest, the county criminal police captain can still live a comfortable life. Even if he does not pursue enjoyment and power, it is not difficult to find some good educational resources for his children, some good medical resources for the elderly, help his family arrange some jobs, and find some business prospects.

It would be better if senior police chiefs like Liu Jinghui and Qiu Yue had a real job. Those who are floating around the province are really floating in the air. Apart from fame, they can't get anything.

"Should we invite Director Qiu to come?" Captain Han was a little soft-hearted.

"Then please invite him to come, just ask him not to affect Jiang Yuan." Liu Jinghui didn't really care.

After a while, Qiu Yue, wearing a vest of an old cadre, followed Captain Han in.

Qiu Yue, who was in his fifties, looked like he was in his fifties. His skin had a lot of wrinkles and dullness, and he looked listless. When he entered the door, he glanced around and observed the people everywhere, with a little brilliance in his eyes.

"Director Qiu." Liu Jinghui took the initiative to greet him.

"I heard that you have reopened the Qu'an station explosion case, so I came to ask if there are any clues?" Qiu Yue spoke standard Mandarin, which was a little unfamiliar and a little stiff.

Captain Han said beside him: "Director Qiu, this year is the year for our Qinghe City Bureau to crack down on backlog cases and murder cases. The Qinghe City Bureau organized a backlog case cleaning operation."

According to the normal police case-solving process, such backlog cases will only be reopened if there are considerable clues. Otherwise, it will take longer to start looking for clues after the restart. The most important thing is that if no clues are found, it will be a lonely restart.

However, this method also has disadvantages, that is, the clearing of backlogs is very slow. If you don't take the initiative and passively wait for clues, it is likely that year after year, and finally it will be even more impossible to solve the case.

Therefore, the backlog clearing operations organized by ministries, provincial departments or municipal bureaus are the so-called "not waiting and not relying on", which sacrifices a certain efficiency. From the perspective of social governance, it is definitely worthwhile.

Qiu Yue said "Oh" and asked, "How is it now?"

He looked at Liu Jinghui, and at the same time, his eyes were also searching for Jiang Yuan's figure.

Being in the Shannan Provincial Police, even if he is a marginal figure, it is impossible not to know Jiang Yuan. And Liu Jinghui is also somewhat famous in the upper echelons of the provincial department and the county bureaus-the reasoning master is still very particular, and besides, it is still rare for a policeman to be held down by a serial killer.

Liu Jinghui smiled and said, "The case is progressing."

"Are there any key breakthroughs?" Qiu Yue was also a person who had played thoroughly in the front line. He felt that it was a bit too blunt to say it in one sentence, so he said, "I followed this case from beginning to end. I arrived in Qu'an County the day after the case was reported. After that, I also thought about it repeatedly, maybe I could help."

Liu Jinghui knew that Qiu Yue was unwilling to give up when he heard his tone. In fact, there was no need to listen to his tone. You can also use reasoning to think that if you can think clearly, Qiu Yue should be lying at home now. What's the fun of working on a case? It's tiring and you have to take responsibility!

Liu Jinghui hesitated for a few seconds and said, "No breakthrough for the time being."

Qiu Yue was not surprised and asked, "Where is it stuck?"

"It can't be said to be stuck. We are now using a new plan."

"What new plan?"

"You are asking too many questions." Liu Jinghui half joked and half pushed back.

"Director Liu, this case is really a knot in my heart." Qiu Yue's tone was serious, and his expression did not show any rebelliousness.

Time had already smoothed his edges.

Liu Jinghui was a little touched by it, but still did not respond directly. Instead, he decided to hand over the problem: "Han Da, can you report to Director Wang?"

Liu Jinghui came here to help and did not want to be so involved.

Captain Han had no choice but to make a phone call.

Not long after, Deputy Director Wang, who was in charge of criminal investigation at Qu'an County Bureau, came to the meeting room.

He knew the situation when he came. He smiled and said a few words to Qiu Yue, and then said: "We have agreed that if you want to know the situation, you can, but you cannot interfere or interfere with our affairs. Otherwise, we will Expelled people."

"Don't worry, I'm just taking a look. Unless you need me, I won't say anything." Qiu Yue agreed immediately. In fact, he is not afraid of not having a chance to speak. This case is complicated, and many details will not be reflected in the file.

Although Qu An also had veteran detectives involved and knew about the events that day, he, the person in charge, must know more and more comprehensively.

It was with this in mind that Wang Bureau immediately agreed to Qiu Yue's participation. He doesn't care about anything else. Being able to break the eucalyptus is his biggest goal.

Everyone thought about their own things and went to the conference room next door together.

At the same time, Captain Han introduced Jiang Yuan’s ongoing work, many-to-many footprint comparison.

Qiu Yue was stunned upon hearing this, not in admiration, but in a state of feeling stupid.

Because he knows about footprint identification.

In fact, the veteran criminal police used footprint identification in the early years.

Unlike abroad, where footprint identification can only identify shoes, domestic footprint identification can identify people. In this way, the value of footprint analysis is greatly improved. Especially in the era without DNA technology, footprint analysis is a powerful tool for criminal police.

However, Qiu Yue had just said that he would only watch and talk, and Qiu Yue was not easy to ask questions, so he frowned and prepared to observe and then ask them how to use the footprints eight years later to compare with the footprints eight years ago.

In his opinion, which is somewhat knowledgeable, this is even more outrageous than using the sword of the previous dynasty to kill the officials of this dynasty.

meeting room.

Spread across the water are hundreds of monitors, displaying all kinds of footprints.

Jiang Yuan walked slowly in front of the tables, switching between tables from time to time.

Many-to-many footprint comparison means that it takes a lot of time to eliminate a footprint. It can be said to be very troublesome.

Of course, in Qiu Yue's view, this is more like a modern version of the emperor's new clothes.

A group of people watched Jiang Yuan perform there, but no one dared to tell the truth: There are footprints from 8 years ago... When people from 8 years ago stand in front of you, some of them are unrecognizable.

Qiu Yue snorted impatiently.

He has been acting bad for a long time, but a person's personality will not change much. He still can't stand it when he encounters something he can't stand.

The noise made by several people disturbed Jiang Yuan. He looked back and just nodded.

LV5’s footprint analysis is quite easy to use, but it’s also tiring.

This is just like a mouse impregnating a cat. No matter whether the big mouse is a great master or in the innate realm, riding a cat is always very hard work, and coming up with results is even harder.

"We're just taking a look. Don't be too tired. If you can't, just take a rest." Liu Jinghui felt a little distressed when he saw Jiang Yuan's condition. In order to help himself verify that "there is only one truth," Jiang Yuan was really under a lot of pressure.

"The progress of the footprint comparison is very slow." Jiang Yuan first gave Liu Jinghui a conclusion, and before he could be disappointed, he added: "However, I noticed a footprint that stood nearby for a long time, which was a bit too long."

This is something Jiang Yuan saw last night, but since it is not conclusive evidence, there is no need to send it out in a hurry.

Liu Jinghui asked: "How do you define standing for a long time?"

"Standing for an hour or two, or two or three hours, right near the explosion point. Moreover, similar footprints also appeared next to the explosives." Jiang Yuan gave a brief description and marked a few points on the map. position.

The map was a temporary map of the explosion range that had been made previously. There were a lot of things marked with 1234 on it. Jiang Yuan drew a few triangles with a water pen, and Liu Jinghui immediately saw the mystery.

"Is this around the explosion point? Is there a trash can in front of you? You have been standing next to the trash can for so long, smoking?" Liu Jinghui said, he had already started to shake his head: "Where is the person smoking for an hour or two? I really miss myself. Donating a carrier-based aircraft is not enough.”

"These are the footprints from the second day." Jiang Yuan drew a few more circles.

After the explosion, a lot of people came to watch, especially residents living nearby, who came to take pictures with their mobile phones. Simply put, it is unreasonable to say that the criminal returned to the crime scene.

However, the few mentioned by Jiang Yuan were indeed suspicious. Liu Jinghui groped his chin and said, "Let me think about it, how can I find this person out? Does he have any characteristics?"

"Height 1.6 meters, male, weighing about 110 kilograms. This is data from 8 years ago. He is relatively thin, but he should be exercising, and he walks faster..." Jiang Yuan relied on LV5's footprint analysis to give Judgment is more accurate.

Qiu Yue couldn't bear it anymore and whispered: "After standing there for two or three hours, how did you find out through the footprints?"

Jiang Yuan glanced at him. Although he didn't know him, he looked at the police uniform and said, "When people stand, most of the time they don't stand still. Instead, they change postures from time to time, and the center of gravity on the footprints will change." Shifts and changes have occurred…”

"Then why is it two or three hours, not seven or eight hours?" Qiu Yue is not arguing, he just has too many questions.

Jiang Yuan only shook his head slightly: "There is a rate of change."

In the past, this could not be seen in the footprint analysis at LV3. It can only be seen after reaching LV5. It can be said that after the footprint analysis skills are improved to LV5, the biggest change is the increased understanding of time.

Correspondingly, if the other party does not have 9's footprint analysis, it is meaningless to explain, just like explaining the strategy of riding a cat to a white mouse, which is useless.

"Isn't this person on the victim's contact list?" Captain Han asked.

Jiang Yuan shook his head: "No."

There is no substantial discovery in the multi-to-multi footprint analysis.

Liu Jinghui looked at the location on the map and pondered: "If it doesn't work, you can look at the video footage of the scene. Maybe you can run into this person. He has been wandering around for so long, maybe you can take a picture of him..."
