National Forensic Doctor

Wu Xia is a fingerprint expert in Anping Province and is also a trace examiner. However, in terms of the level of trace identification alone, he may be at the level of 8 to lv3, which is not as good as the level of fingerprints.

Therefore, Wu Xia is a trace examiner with expert fingerprint identification skills, but he is mainly a fingerprint expert and cannot understand the trace photos given by Jiang Yuan

This is naturally quite abnormal!

Wu Xia has basically never encountered this kind of situation.

As far as his mark inspection level is concerned, it is normal that there are marks that he cannot make, so why can't he understand them?

Next door, Zhang Xian, an expert on real 8 ministries and trace inspection who was also looking at the photos, slid over.

He noticed Wu Xia's expression. The criminal police officers are all old and clever, and their ability to read people's eyes is as if they have stayed at a relative's house for 30 years. They immediately looked at a few photos on the table.

"Are there the same traces?" Wu Xia asked directly.

Zhang Xian, who is a nationally recognized figure in the ministry and commission and often gives lectures in various places, was eager to win. He stared at the photo for a long time, then put on his horse hoof glasses, pointed to the instrument panel on the right side of the steering wheel, and said : "You're talking about this scratch, right?"

On the plastic dashboard, there are both traces of dirt and scratches on the plastic. They are vertical, horizontal, and zigzag. It can be said to be a mess.

Zhang Xian worked very hard to study the addiction. In this kind of situation, everyone who is famous has a first name and a surname. He would never joke about his reputation in such a semi-public place.

, In fact, when the three of them gathered together, it was already a bit like an expert consultation. What everyone said may be the topic of conversation at other people's dinner tables in the future.

There was no hint of understanding on Jiang Yuan's young face, and he said calmly: "There are certain similar patterns here on the dashboard, here on the armrest box, including the scratches on the steering wheel."

Jiang Yuan pointed at the photo and moved it.

Looking directly at the photos, the traces mentioned by Jiang Yuan are too thin, so thick that they can’t be seen even if you don’t smoke carefully.

Even with the magnification of a horseshoe mirror, these scratches can only be said to be visible. It is somewhat reluctant to say that they are the same, or that they come from the same person.

Zhang Xian was a little older and didn't want to waste his eyes too much, so he closed his eyes and followed, recalling the traces he had just seen and making judgments secretly.

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

This kind of trace may not be specific if you say it alone. It is like two people using a cane to slap a third person on the buttocks. The cane is the same, and the individual marks extracted are naturally similar. Although there may be a difference in depth and length, it is difficult to prove.

But if two people were whipped a dozen times, or even more, to form a whip mark, then as far as the entire whip mark is concerned, they will have certain differences and specificities.

But it goes without saying that this method of identification is less accurate and several times more difficult.

"How do you think this trace was formed?" Zhang Xian was reminded by Jiang Yuan and basically agreed with 60%. Both cars were stolen and both had newly formed traces. That means they were created by the same group of people. Because, there is a high probability.

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

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

The movements simulated by Jiang Yuan were exactly the movements caused by certain scratches on both cars.

Take the same example of a whip being slapped on the buttocks. Whether the whip is whipped in anger or in excitement, even if the same person slaps the whip on different people's buttocks, the whip marks may look messy.

But if you analyze it carefully, you will usually find that the whip marks on the two buttocks always have something in common.

Without deliberately changing the action

, a person's height, weight and whip swinging movements will always have something in common, which can be regarded as part of muscle memory.

Jiang Yuan found the similarities between the scratches on the two cars.

Using trace evidence of this level in court may require a little bit of procedure and trouble. But at the investigative stage, it's enough to make a decision.

"I agree." Zhang Xian thought for a moment and supported Jiang Yuan's judgment.

He also saw that Jiang Yuan's qualifications were not high enough, so he specifically supported Jiang Yuan. As a technical expert listed by the ministry, Zhang Xian knows that some young technicians often encounter a crisis of trust. For example, Gao Changjiang, the director of the Guqi Municipal Bureau, can only be said to partially trust Jiang Yuan. In fact, it was not easy. At least Gao Changjiang could listen to Jiang Yuan's opinions, but he didn't seem to trust Wolong Fengchu.

After Zhang Xian said "agree", Gao Changjiang's expression immediately changed and he immediately looked at Wu Xia.

In terms of familiarity, the one he trusts most is Wu Xia, an expert from this province.

Although judging from the performance of the three of them, Wu Xia seems a bit inferior to Zhang Xian and Jiang Yuan, in terms of trust, Gao Changjiang has never seen Wu Xia show off his power.

After the conversation between Zhang Xian and Jiang Yuan, especially Jiang Yuan's explanations and gestures, Wu Xia understood the traces on the photos. After being consulted by Gao Changjiang's expression, he also said: "What Jiang Yuan said makes sense."

Gao Changjiang didn't hesitate anymore and issued a series of orders;

"Check the license plates of these two cars and retrieve the vehicle information. Pull out the case of the missing car and ask for surveillance. Lao Zhou, take a few people to the scene of the missing car to see if you can collect any other images. Ask Ask the merchants around you."

"Car rental company, is there a car that is not the car rental company's car? Zhu Hongbo, take people to the car rental company, adjust the monitoring, and get the GPS information to see where they have gone. Make notes for the people at the car rental company, The people who were looking for the car at that time were brought back and asked about it carefully."

"You are not allowed to move inside the car. Just ask a truck to tow it to our garage, and let the fingerprint inspector scan the fingerprints and DNA."

"Well...Director Wang, I leave the image tracking to you. See if you can find the whereabouts of this group of people through the locations where vehicles pass and stop along the way."

Gao Changjiang dispatched his men with ease and skill.

He is a director who came from the front line, and he has directed many cases to be solved. However, the difficulty of this case is too high, and the criminals committed the crime in a well-planned way, so it is not easy to solve it in a short time. However, his ability to get ministries and commissions to support experts and immediately arrive at them is part of his ability.

Jiang Yuan only added: "The car has been delivered and I will investigate."

His level 4 crime scene investigation skills are among the best in Guqi City.

For an expert like Zhang Xian, even if his on-site investigation skills are very good, regardless of his age, it would be difficult to do better than Jiang Yuan.

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

Jiang Yuan nodded. Unless the vehicle is deeply cleaned, there is a high chance that dander, hair, fine hairs, saliva, nose hair, pubic hair, eyelashes, etc. will be left in the vehicle.

Jiang Yuan feels that this step may not be necessary, because the vehicle can provide a lot of information. Even if several criminals use the joy ride method, which has reduced the probability of being discovered, when the vehicle is identified, they can escape The probability has been greatly reduced.

This time, they still had no clues for their subsequent crimes. It doesn't matter if the car is repossessed by the car rental company. Rough car companies lose a lot of cars, and the police won't investigate them without a reason.

However, the criminals gathered in the countryside to commit crimes, leaving too many ties, including the abandoned red Santana, which also became a breakthrough point. If they don't abandon the car, they will still face high risks, especially if the police can follow the cameras on the road, and it will be difficult for them to drive the car back to their residence. Finding a place to stop would be inconvenient, making escape more difficult.

In other words, there is no strict recourse for attempted abduction.

There are cases

After seeing the progress, the members of the Guqi City Bureau's task force became excited, but Jiang Yuan became quiet next to them.

Soon, the first clue came through.

"The ID card they left for the car rental company was bought, but they used the same ID card to check in at Shidong, and the ID card they checked in with also rented a car from another car rental company. The GPS showed that the vehicle was in motion. On the highway... let's arrest people now." Gao Changjiang went out for a trip, and when he came back, his whole body was full of murderous aura.
