Chapter 631: Blooming

"If the evidence surveyed by the technical personnel is problematic, then we have nothing in this case," Tao Lu thought for a while, his expression slightly frustrated.

For them, this case also involved a lot of time and energy. If they had to start over... Tao Lu wasn't afraid of his subordinates working hard, but this case was no longer a current case. Many pieces of evidence were gone, and new ones couldn't be found.

"That is indeed a problem." Jiang Yuan touched his chin, thought for a moment, and said, "Which evidence can be used and which cannot, we can find a way to screen it later. I think we can confirm the palm prints first. Because I looked at the initial investigation direction, it was believed to be a crime committed by an acquaintance, and because of this, palm print comparisons were done on the villagers of Fangxia Village and the victim's relatives and friends."

Tao Lu's face turned gray, as if someone had rubbed pot ash and then rubbed it onto his face, giving it a light, excessive gray feeling.

Tao Lu said in a deep voice: "If there is a problem with the palm prints, does it mean the killer might have slipped past our eyes?"

"It's not certain yet." Jiang Yuan used a little bit of emotional intelligence. After all, it was the result of hundreds of people working hard for a long time. If it was just because of the carelessness of a few criminal science personnel...

It can only be said that the conditions of the criminal police in Jingcheng are still a bit good, and they have encountered too few unreliable technicians. If it were in Shannan, they wouldn't even need to have a bottom-tier trash like the Longli County one appear. Just Comrade Wang Zhong from Ningtai County, with that Level 0.5 on-site investigation ability, if he wasn't careful, problems would arise.

This is nothing strange. In the world, there are people who just muddle along. Some people can't find work, some people become civil servants, some people become police, some people become doctors, some people become writers. Everyone has a side that just lets things rot.

Even among dogs, there are meritorious dogs like Da Hei, as well as useless "doggy" dogs.

"What do you want to do?" Tao Lu adjusted his mood.

Jiang Yuan said: "My suggestion is to do a palm print comparison for all the police officers who participated in the investigation."

"This... okay. Check early, rest easy." Tao Lu sighed. This decision definitely had some resistance, but it wouldn't be too big. Honestly, it's not fresh for on-site investigation personnel to leave their own fingerprints or DNA at the scene. Even in countries with bright lighthouses, it's the same.

"What's next?" Tao Lu asked.

"If there is indeed a problem with the palm prints, then we will re-investigate according to the acquaintance crime method, following interpersonal relationships and other aspects, to see if there are any obvious criminal suspects. During this period, I will study the evidence in the case again."

Seeing Jiang Yuan's calm expression, Tao Lu suddenly felt a bit envious.

Actually, if the palm prints were excluded, this case would be equivalent to starting the investigation all over again. And re-investigating a case actually has many mature plans to follow. Unless Jiang Yuan chooses some kind of unconventional plan, it's basically the same mode, which Tao Lu could arrange with his eyes closed.

But being as young and confident as Jiang Yuan was something Tao Lu didn't possess.

Even now, Tao Lu couldn't help but worry about gains and losses, and couldn't help but shake his head, saying to Jiang Yuan: "You're not worried about the case hitting a dead end."

"We'll talk about it when we hit a dead end." Jiang Yuan really wasn't too afraid of this. Not to mention that cold cases don't have the pressure of must-solve, just the act of solving the case itself—a killer who commits a crime so crudely, why would he be able to beat the fully armed Jiang Yuan?

Returning to the police station, Tao Lu arranged things in a tight and orderly manner.

The police station and the criminal police team are not affiliated with each other, so he also had to find the bureau chief to coordinate. On the other hand, the technical personnel sent by the criminal police team that day also had to be checked, and those participating in cases outside also had to be called back.

With such a check, before the verification even started, the team was already boiling.

Cui Qishan, the detachment leader of the Fourth Detachment, took the opportunity to recruit troops and first pulled up a small group, saying: 【The forensic doctor from outside also looks at us coldly. Don't say we are the party paying the money; even if we were freeloading, according to the way it was before, he couldn't be like this, right? So, to forge iron, you have to be strong yourself. Our own task force solves the case beautifully, and then we will stand firm.】

Xiao Si said:

【These cold cases were all left by ourselves. We didn't solve these cases before because we didn't like them?】

Cui Qishan: 【Don't say these sarcastic things. Which year do we not solve three or five cold cases when we do cold case clearing?】

Xiao Si: 【That was several times the task force, working together for several months, to be able to do it. Our current cases this year are not few.】

Cui Qishan: 【The previous task forces were all pulling personnel from one detachment to another. This time it's different. We are going to set up an elite group this time, all backbone criminal police. Can the combat effectiveness be the same?】

Wang Chao: 【Are the people in this group all elites?】

Cui Qishan: 【That's right, are you a little happy now.】 ===== CHAPTER 632 =====
