Chapter 181: Division of Labor and Cooperation

A journey of 1,600 kilometers, over 3,000 kilometers round trip, with only one day of rest in between.

When Jiang Yuan returned to Ningtai County, he was completely dazed.

If someone asked him what Luojin City was like now, Jiang Yuan could only ask in a slow speed: "Luo what?"

Even so, Jiang Yuan was still receiving special treatment.

The other three were driving and escorting Liu Yuquan. Similarly, not sending four people but sending three to escort was already considering the comfort of the long journey.

Huang Qiangmin came to the forensic office with a 22.2-degree smile on his face the whole way. Seeing Jiang Yuan's exhausted look, he couldn't help but laugh, "Look at you, you're exhausted, aren't you? I said don't go on the arrest, let others run."

"I was thinking, maybe I'd encounter work that requires finding clues at the scene or finding evidence." Jiang Yuan had rested for one night yesterday, still looking like he hadn't recovered, but for the sake of the brigade captain, he still stood up.

Huang Qiangmin handed Jiang Yuan a cigarette, handed one to Wu Jun, and after Wu Jun lit it and took a puff, he said, "Your idea is quite good. Indeed, facing cold case murders, we should go all out. However..."

Huang Qiangmin said this, turned around, and closed the office door.

Behind the door, Guan Erye was hanging, swaying, his phoenix eyes looking at people sideways.

Obviously, Comrade Wu Jun had some alternative cognition about how comrades returning from other provinces refresh themselves and perfect themselves. And the ritual had not yet been completed.

Huang Qiangmin's mouth twitched twice, and he turned around pretending not to see it.

"Let's close the door and say something politically incorrect. Jiang Yuan, clues at this kind of arrest scene can be done by anyone. Even if you encounter something particularly difficult, collect it and send it back, and it's the same if you analyze it later. If not, if you must go to the scene, it's not too late to go temporarily." Huang Qiangmin's voice was significantly lower.

Wu Jun coughed twice and hurriedly said two politically incorrect things, "Jiang Yuan, the brigade captain is truly concerned. I also agree. You have the ability to solve the case; leave the arrest work and the subsequent work of completing the evidence to others."

"Yeah, everyone has their own expertise, division of labor and cooperation." Huang Qiangmin felt he had said it right.

He suddenly had a particularly strong desire to say these words now, also because the strength Jiang Yuan displayed was too astonishing.

A murder case from 13 years ago was solved as soon as it was restarted, and it was a hit every time.

The criminal suspect confessed some criminal details on the road, and Huang Qiangmin was also impatient to verify them; the results went without saying.

Cases like this were all kept secret, especially some details of the crime, such as which part of the clothes was torn, which object at the scene was moved, or where the murder weapon was hidden, how the bloody clothes were handled, etc., were all kept secret.

Some content wasn't even written into the case files. It was something that could only be seen or heard by going to the scene, or even only at the scene.

Once these detailed contents were confirmed, the identity was confirmed.

In current cases, let alone murder cases that require on-site identification, some theft cases also have on-site identification links, which is equivalent to confirming the effectiveness of their confession from another aspect.

The 611 He Jingqin case was also a case Huang Qiangmin personally handled after he took office as the criminal police brigade captain.

How difficult it was to do this case back then, Huang Qiangmin felt emotional just thinking about it.

It's just that the criminal investigation direction considered at the time was wrong. Because there was no fact of rape, and there were burglary cases in the building where the victim lived within a few months, it was mainly considered from the perspective of murder caused by seeking wealth.

Later, it was even considered whether it was murder caused by hatred due to He Jingqin's parents' relationships, or attempted kidnapping.

At the time, because this case happened in the tallest building in the county, it attracted a lot of attention, especially the panic of the residents in the building and nearby residents. It also caused a relatively large social impact, and the special task force was sleepless and worked day and night.

Huang Qiangmin slept for only four hours a day for two consecutive weeks, half of which was slept in the car.

Other members of the special task force were also commendable in their work enthusiasm and fighting spirit. When the special task force had the most people, it broke a hundred, and for a period of 3 months, there were thirty or forty people pouncing on this case.

However, solving a case really isn't something that can be achieved just by having enthusiasm and fighting spirit.

If calculated by working hours, the He Jingqin case 13 years ago had at least 70,000 to 80,000 man-hours invested by Ningtai County's police system, and the later years of clearing cold cases also had hundreds of hours of man-hours invested in this case.

But how many man-hours did Jiang Yuan use?

Jiang Yuan restarted the case for 10 hours, maybe just a few hours of working time, and the later arrest probably used hundreds of man-hours.

A hundred times the work efficiency.

The most critical thing is that the way this case was solved is different from the fingerprints, DNA, and footprints Jiang Yuan used before.

The technology of reconstructing the crime scene actually shows more than just giving a direction for solving the case.

It creates a platform.

As long as Jiang Yuan reconstructs the crime scene, members of the special task force can understand the full picture of the crime scene.

It's equivalent to letting everyone see a bloodstain video of the crime scene.

And with this foundation, solving the case is obviously much better than just relying on a fingerprint or DNA to hit luck.

This big livestock can really open up wasteland!

Huang Qiangmin didn't urge Jiang Yuan, patted his shoulder again, said two kind words like "rest well," opened the office door, and went out.

He didn't even look at Guan Erye again.

Wu Jun stepped forward to put Guan Erye away, thinking about putting it in a different place next time.

Jiang Yuan's state was poor, and he was powerless to do anything else, so he read a novel for a while and got off work on time.

The next day, Jiang Yuan arrived a little late.

Liu Yuquan had already been properly locked in the detention center, and the procuratorate had intervened in advance.

During this period, the Ningtai County Bureau, which had solved cases one after another, also created no small pressure on the upstream and downstream units.

However, solving cold case murders is always a good thing.

Some people have already started considering how to write their work reports.

Jiang Yuan entered the office and saw Wu Jun writing furiously.

This made Jiang Yuan feel a bit emotional: don't talk about civil servants being idle; look at Wu Wu Fa Yi Wu, a cup of clear tea, a cigarette, a water pen writing all day, writing without stopping.

"Master, what are you writing? Can you share some with me?" Jiang Yuan finished his emotion, took the initiative to step forward, and prepared to work.

Wu Jun looked at him, sighed, and said, "Forget it, it's all stuff I'm familiar with. If I let you do it, Brigade Captain Huang will scold me for not knowing how to behave later."

"How could that be..."

"Old Crocodile is difficult to deal with." Wu Jun shook his head and said, "The injury appraisal done a few days ago, just finish it. If you have time, go do cold cases."

"I can't do cold cases every day either." Jiang Yuan laughed.

Wu Jun didn't laugh, looked up at him, and said, "Did you forget what Brigade Captain Huang said to you yesterday?"

"Uh... basically."

"It's normal to set up a special task force to do cold cases; it's normal for a case to take two or three months. How much time did you spend? What do you mean by doing cold cases every day? Since you've started, you have to get something out of it, at least." Wu Jun educated Jiang Yuan.

Jiang Yuan laughed twice and said, "Didn't I just finish a cold case?"

"Time is also very important," Wu Jun said earnestly. "Brigade Captain Huang started arranging for some teams to finish cases quickly in the group yesterday. Guess what he's tossing about wanting to do?"

Although Jiang Yuan didn't understand, he followed the meaning and said, "Do cold cases?"

"Right, so, how much time do you think you really have to waste? Hurry up. Brigade Captain Huang is ready to cooperate with you, but you ended up accompanying me to write documents for half a day... Brigade Captain Huang could tear me apart."

"Not to that extent..."

"Are there few stories of killing the chicken to warn the monkey?"

"Am I the monkey?" Jiang Yuan pointed to his own nose.

Wu Jun nodded.

"Are you the chicken?"

Wu Jun also nodded.

Jiang Yuan silently returned to the computer to work.

It took Wu Jun a long time to realize, and he smoked half a cigarette in one breath, considering that Jiang Yuan used the word "you" (polite form), he temporarily spared him.

Jiang Yuan continued to flip forward from the cold case 13 years ago, and then he flipped to a case 17 years ago.

A corpse found by a country road.

Because of the obstruction of trees, it wasn't until the corpse gave off a foul smell that passing pedestrians reported it.

The case stopped here...

Jiang Yuan noticed it because the police officers who investigated the scene at the time found one-third of a bloody fingerprint on the deceased's leather jacket.

Seeing this fingerprint, Jiang Yuan had a strong urge to compare it.

"It'll be you." Jiang Yuan recited silently, moved his chair, and looked closely at the screen. ===== CHAPTER 182 =====
