Chapter 54: Trace Evidence

Early morning.

Jiang Yuan woke up from the bed, full of energy and relaxed, feeling as if he hadn't participated in the special task force.

In fact, there was no part for him to participate in.

As far as forensic medicine is concerned, the City Bureau has old forensic doctors who are so experienced that they only wear masks even when they go to the corpse green scene, and there are also dedicated doctoral forensic doctors who can have a corpse dissection in two weeks.

As far as criminal police are concerned, the City Bureau's Criminal Police Detachment has many cattle people who have solved major cases, and there are also rough men who are like social butterflies.

And Jiang Yuan and others from Ningtai County were not treated as cattle and horses, but were taken care of by the detachment captain. Knowing that a group of people had been staking out for so many days, they were given a few days of breathing time.

Woo woo woo...

Wei Zhenguo's phone rang, and he shouted as soon as he picked it up: "Come down for breakfast. The fried dough stick shop at the door."

Jiang Yuan smiled bitterly, turned over, and still climbed up.

After the case was solved, the accommodation conditions in the new place were greatly improved. In the past, criminal police went on business trips, mostly in double rooms and express hotels. This time, Wei Zhenguo booked single rooms for everyone, and the hotel was not just where it was cheap. At least it shows that after the case was upgraded to the special task force, their funds were also a little more.

Downstairs, the most lively place is the fried dough stick shop.

In the boiling hot oil, the rolling noodles constantly stretch their arms and kick their legs, constantly expanding and getting bigger. In just a few seconds, its volume is several times larger than the original dough. That hot oil is like rising desire, using the most intense means to make the two bonded dough expand, make them bigger, make them change color, make them sweet, and also make them lose water, lose stickiness, and lose the original appearance of flour.

"Three fried dough sticks, a bowl of tofu brain, a bowl of soy milk. Side dish, bring an egg," Jiang Yuan touched his stomach and ordered a pile of things for himself.

Wei Zhenguo drank soy milk and said: "Youth is good, I can't eat it anymore."

"Anyway, there is nothing to do," Jiang Yuan paused and asked: "By the way, can I go for an autopsy?"

"It's all bones," Wei Zhenguo looked at Jiang Yuan and said: "Team Yu's side, definitely still believes in their own forensic doctors. If you do it, he won't recognize it."

"I can do bones now," Jiang Yuan just obtained the LV3 skill of forensic anthropology, so he must be fine on the battlefield.

Wei Zhenguo advised: "It's better not to go. If you go, you are also helping their forensic doctors. If something goes wrong, it's easy to take the blame."

Mu Zhiyang on the side said: "It's not your own livestock, so you don't feel bad when using it. And they don't know you."

"That's right, I was borrowed before, and the goods were used too hard," Wen Ming, a criminal police officer who came with him, also sighed with emotion. Although everyone was used as livestock, they would cherish their own livestock more.

Jiang Yuan could only lower his head and drink soy milk.

In Ningtai County, his strength was obviously much stronger than his colleagues, but when he arrived in a provincial capital like Changyang City, that was not necessarily the case, so there was no need to rush to do an autopsy.

Several criminal police officers ate breakfast quietly, and in a trance, they ate a taste of years of quiet and good.

"I want to follow their crime scene investigation and take a look at the evidence," Jiang Yuan finished the soy milk and had a new idea, saying: "I see Director Liu didn't make relevant arrangements, can we do it?"

"It can definitely be done," Wei Zhenguo asked puzzledly: "What do you want to do?"

Jiang Yuan thought for a while and said: "I want to see Tan Yong's car."

"His car? Do you want to find out where he might have been through his car?" Wei Zhenguo could think of the reason as soon as he thought about it, but he was not optimistic and said: "The Changyang City Criminal Police Detachment has already checked the car to the bottom."

"That's even better, we'll check it again, and it won't affect their investigation." So far, Tan Yong still hasn't confessed, so investigating based on existing evidence is the most direct idea.

And the LV4 crime scene investigation skill is also Jiang Yuan's strongest skill at present.

And by investigating Tan Yong's car, Jiang Yuan can find more clues—whether the case can be solved is a matter of probability, and the more clues found, the closer to solving the case.

Wei Zhenguo thought for a moment and nodded: "Then I will accompany you to find the crime scene investigation."

Two hours later.

Jiang Yuan, Wei Zhenguo, and Mu Zhiyang stood in front of Tan Yong's Pajero.

The captain of the crime scene investigation squadron, Cao Zhouquan, answered the phone and came out. He had a good impression of Jiang Yuan. When they met, he first gave a traditional smile, looking atmospheric, and then said half-jokingly: "Are you unconvinced? We have wiped Tan Yong's car clean, it is impossible to leave it alone."

Jiang Yuan was able to endure not entering the dungeon outside the dungeon, which made Cao Zhouquan talk about it for two days, and what he said now was also this.

Wei Zhenguo laughed and said: "Our Xiao Jiang has some ideas, Captain Cao, don't think too much."

"It's okay, you want to do it again, I have no opinion. Besides, you left such a big basement to us, it's nothing to let you wipe the car again," Cao Zhouquan said and did things quite atmospherically. After speaking, he shouted again: "Du Lei!"

Then, turning his head, Cao Zhouquan introduced: "Tan Yong's car, Du Lei followed me to wipe it before. This time, wipe it with you."

Cao Zhouquan said he didn't mind, but he probably minded a little bit, so he called his capable subordinate out.

Being able to wipe homicide evidence, and in a place like Changyang City, it certainly can't be a weak hand.

Du du du.

A balance car slid directly in front of Jiang Yuan.

"Du Lei." On the balance car, Du Qiang was wearing a police uniform, and his waist was thin and long, looking like he could be kicked off with one kick.

"Xiao Jiang and the others want to wipe Tan Yong's car again, you follow along," Cao Zhouquan said directly.

Du Lei frowned at Jiang Yuan and the others and said: "The inside is basically dismantled, and the wheel guards below are also dismantled..."

"I want to find trace evidence," Jiang Yuan didn't mean to hide it, and while making gestures, he said: "Just because this car has traveled on bad roads, it is more likely to leave debris, seed pollen, or hair feathers from the scene inside. Dismantle it and take a look, maybe you can find something."

The reason why the crime scene investigation skill he mastered reached the LV4 level is reflected at this time.

Jiang Yuan said it with confidence, and most importantly, what he said was indeed reasonable.

Cao Zhouquan asked unexpectedly: "Does your county bureau have a trace evidence laboratory?"

The laboratories of criminal science are relatively simple, many of which are at the level of middle school chemistry laboratories, usually DNA laboratories will be more expensive.

What kind of laboratory to build is related to needs and personnel in the unit. It can be said that many laboratories are set up for people. With relevant talents, relevant laboratories are built, such as the poison testing laboratory in Ningtai County, which is because there was a need for poison testing back then, and also because Lu Jianfeng, the captain of the Criminal Science Squadron, had talent in this area.

Cao Zhouquan heard Jiang Yuan confidently talk about the trace evidence laboratory, and couldn't help but be shocked. This thing is really expensive.

Jiang Yuan shook his head at Cao Zhouquan: "Ningtai County does not have a trace evidence laboratory."

Cao Zhouquan, a calm traditional handsome man, was angered and laughed: "What are you talking about if you don't have it."

"You can use Changyang City's. Or send it to the Provincial Department's trace evidence laboratory," Jiang Yuan said.

"The city's is also a sample. The trace evidence laboratory is complicated, the cost is high, and there are many instruments and equipment. The Provincial Department doesn't do it very well," Cao Zhouquan shook his head and said: "So I said there is no need to dismantle it again. You can't dismantle anything, and it's thankless."

"Whether trace evidence works depends mainly on extraction. Laboratory operation has a lot of room for error," at this time, Jiang Yuan didn't have any modesty, and emphasized again: "As long as we extract things, we have a chance to do it in any laboratory."

"Alright," Cao Zhouquan had nothing to say and simply agreed. Anyway, he is not the one doing the work. ===== CHAPTER 55 =====
