Chapter 341: Approval

Wu Xia is a fingerprint expert in Anping Province, and also a trace examiner, but in terms of the level of trace identification alone, he might be hovering at the LV2.8 to LV3 level, not as good as his fingerprint level.

Therefore, Wu Xia is a trace examiner with expert-level fingerprint identification skills, but mainly a fingerprint expert, and he couldn't understand the trace photos Jiang Yuan gave...

This is naturally quite abnormal!

Wu Xia had basically never encountered this situation.

With his trace examination level, it is normal for there to be traces he can't do, but why can't he understand them?

Zhang Xian, the true LV4.8 ministry-named trace examination expert who was also looking at photos next door, slid over.

He noticed Wu Xia's expression. Criminal police are all old clever ghosts. Their level of looking at people's expressions is like having boarded in a relative's house for 30 years. He looked at the several photos on the table for the first time.

"Are there identical traces?" Wu Xia asked directly.

As a ministry-named national-level awesome expert who often goes to various places to give lectures, Zhang Xian felt a competitive spirit. He stared at the photos for a long time, then used a hoof mirror, and pointed to the dashboard on the right side of the steering wheel, saying: "What you said should be this area of scratches, right?"

On the plastic dashboard, there are both traces produced by dirt and scratches produced on the plastic, vertical, horizontal, curved, and folded, which can be said to be messy.

Zhang Xian studied the scratches very hard. In this kind of occasion, anyone who is famous has a name. They will definitely not take their own reputation to joke in this kind of semi-public occasion.

In fact, when the three of them gathered together, it already meant a bit of expert consultation. Every word spoken might be a topic on someone's wine table in the future.

Jiang Yuan's young face couldn't see any panic, and he said calmly: "There are some here on the dashboard, and there are some on this side of the armrest box, including the scratches on the steering wheel. Actually, they all have a certain similar pattern."

Jiang Yuan pointed and slid across the photos.

Looking directly at the photos, the traces Jiang Yuan mentioned were too fine, to the extent that they couldn't be seen without careful looking.

Even using a hoof mirror to enlarge them, these scratches could only be said to be visible. Saying they are identical, or come from one person, is somewhat reluctant.

Zhang Xian was slightly older and didn't want to strain his eyes too much, so he closed his eyes, recalled the traces he had just seen, and made a judgment secretly.

Trace identification can be identifying the similarity of a certain trace, but saying the formation of a certain piece of trace can actually also be used as a template for identification.

This kind of trace, saying one line alone might not have specificity. It's like two people holding a rattan and whipping a third person's butt. The rattan is the same, and the individual marks whipped out are naturally similar. Although there might be differences in depth and length, it is very difficult to prove.

But it goes without saying that if two people whipped more than a dozen times, or even more, forming a piece of whip mark, then regarding the whole piece of whip mark, they have certain differences and specificity.

But there is no need to say that the accuracy of this identification method is lower, and the difficulty is many times higher.

"How do you think this piece of trace was formed?" Zhang Xian got Jiang Yuan's reminder and basically recognized it by sixty percent. Both cars were stolen, and both had newly formed traces. Then saying they were done by the same group of people had a high probability.

"I judge that this driver has the habit of hammering the car. In addition, his right hand should be wearing something, a watch, most likely a cultural play string, so he left these scratches on the right side." Jiang Yuan waved his hands in the air a few times.

Others didn't quite understand, but Zhang Xian and Wu Xia both understood. Jiang Yuan was simulating the action of the driver's right hand waving.

And the few actions Jiang Yuan simulated were exactly the actions that formed certain scratches that both cars had.

Taking the whip on the butt as an example, whether it is whipping because of anger or whipping because of excitement, although the whip marks whipped out on different people's butts by the same person might look messy.

But if analyzed carefully, it is usually found that the whip marks on the two butts always have commonalities.

Without deliberately changing the action, a person's height, weight, and the action of waving the whip always have some commonalities, which can be considered part of muscle memory.

Jiang Yuan exactly found the similar places of the scratches on the two cars.

This degree of trace evidence, wanting to be used in court, might need a little bit of procedure and trouble. But in the investigation stage, it is enough to make a decision.

"I approve." Zhang Xian thought for a while and supported Jiang Yuan's judgment.

He also saw that Jiang Yuan's qualifications were not deep enough, so he specifically supported Jiang Yuan. As a ministry-named national technical expert, Zhang Xian knew that some young technicians often encountered trust crises. Like Gao Changjiang, the director of the Guqi Municipal Bureau, he could only be said to partially trust Jiang Yuan now. Actually, it was quite not easy. At least Gao Changjiang could do listening to Jiang Yuan's opinions, just not like trusting Wolong and Feng Chu.

And after Zhang Xian said the expression of "approve," the expression of Gao Changjiang beside him changed immediately, and he looked at Wu Xia for the first time.

In terms of familiarity, the one he trusted most was the provincial expert Wu Xia.

Although, from the performance of the three people, Wu Xia seemed to be slightly inferior to Zhang Xian and Jiang Yuan, in terms of trust, Gao Changjiang had also seen Wu Xia show off his power quite a few times.

Wu Xia, after the conversation between Zhang Xian and Jiang Yuan, especially Jiang Yuan's explanation and comparison, also understood the traces on the photos. Receiving Gao Changjiang's expression consultation, he also said: "What Jiang Yuan said makes quite a lot of sense."

Gao Changjiang didn't hesitate anymore, and a series of orders were issued:

"Check the license plates of these two cars and pull out the vehicle information. Pull out the cases of stolen cars and find surveillance. Old Zhou, you take a few people to turn around the scene where the cars were stolen to see if you can collect any more images, and ask the merchants around."

"Rental company, isn't there a car that is not a rental company's car? Zhu Hongbo, you take people to the rental company, adjust the surveillance, and ask for all the GPS data to see where they went. Take statements from the people at the rental company, and bring back the people who went to find the cars at that time to ask carefully."

"Don't move anything inside the car. Call a flatbed truck directly to our garage. Let the trace examiners go up to scan for fingerprints and scan for DNA."

"That... Director Wang, the image tracking part is handed over to you. See if you can find the whereabouts of this group of people through the passing and stopping positions along the way."

Gao Changjiang deployed personnel, easily and skillfully.

He is a director who came from the front line, and he has commanded the solving of many cases. It is just that the difficulty of this case is too high, and the criminals are committing crimes with careful planning, so it is not easy to solve in a short time. However, he was able to strive for the support of experts from the ministry and arrive immediately, which can also be considered part of his ability.

Jiang Yuan added one more sentence: "When the car is delivered, I will investigate."

His LV4 crime scene investigation skill, looking at Guqi City, is also the top one.

Like an expert like Zhang Xian, even if the crime scene investigation skill is very top, with age there, it is very difficult to do better than Jiang Yuan.

Gao Changjiang agreed immediately: "No problem. When the car arrives, I will call you immediately."

Jiang Yuan nodded. Unless the car is deeply cleaned, otherwise, the chance of leaving skin dander, hair, sweat hair, saliva, nose hair, pubic hair, eyelashes, etc., inside the car is very large.

Jiang Yuan felt that he might not even need to go to this step, because the information the car can provide is very large. Even if several perpetrators used the method of stealing cars, they had already reduced the probability of being discovered. But in the situation where the car was determined, the probability of escaping had already been greatly reduced.

This time, their subsequent crimes actually still didn't leave any clues. Including the rental company recycling the car, it didn't matter. Rental companies lose many cars. Without a reason, the police wouldn't check there.

But the perpetrator's attempted crime at the rural fair left too many clues, including this abandoned red Santana, which also became a breakthrough. And if they didn't abandon this car, they would still face high risks, especially in the situation where the police could track them along the cameras on the road. It was not easy for them to drive this car back to their residence, and stopping it somewhere would be very inconvenient, increasing the difficulty of escaping.

That is, the pursuit of attempted abduction is not strict.

The case had progress, and the members of the special case group of the Guqi Municipal Bureau became excited. Instead, Jiang Yuan became quiet on the side.

Soon, the first clue was transmitted.

"They used a bought ID card to leave for the rental company, but used the same ID card to handle accommodation in the east of the city. The ID card used for check-in together was used to rent cars at other rental companies. GPS shows that the vehicle is in motion, on the highway... We are going to catch people now." Gao Changjiang went out for a trip, and when he came back, he was already full of murderous spirit. ===== CHAPTER 342 =====
