Chapter 351 Agree
Wu Xia is a fingerprint expert in Anping Province, and also a trace inspector, but in terms of the level of trace identification alone, he may be at the level of LV2.8 to LV3, which is not as good as fingerprints.
Therefore, Wu Xia is a trace inspector with expert-level fingerprint identification skills, but he is mainly a fingerprint expert and cannot understand the trace photos given by Jiang Yuan...
This is of course quite abnormal!
Wu Xia has basically never encountered such a situation.
As far as his level of trace inspection is concerned, it's normal to have traces that he can't make, so why can't he understand them?
Zhang Xian, who was also looking at the photos next door, slid over.
He noticed Wu Xia's expression.Those who are criminal policemen are all old and clever. They look at people with the level of wink, as if they have been boarding with relatives for 30 years. They looked at the photos on the desktop for the first time.
"Are there any similar traces?" Wu Xia asked directly.
Zhang Xian, who is national-level under the name of a ministries and commissions and often goes to various places to give lectures, was full of enthusiasm. He stared at the photo for a while, then put on the horseshoe mirror, pointed to the dashboard on the right side of the steering wheel, and said : "You mean, it should be this scratch?"
On the plastic instrument panel, there are not only marks caused by dirt, but also scratches on the plastic, which can be said to be a mess.
Zhang Xian studied the scratch very hard.On this occasion, anyone who is famous has a name and a surname.He would never make fun of his own reputation in a semi-public situation like this.
In fact, when the three of them got together, it was already a bit like an expert consultation. What each of them said might be the talk of others at the wine table in the future.
There was no trace of panic on Jiang Yuan's young face, and he said calmly: "There are scratches on the instrument panel, and on the side of the armrest box, including the scratches on the steering wheel. In fact, there are certain similar patterns."
Jiang Yuan pointed at the photo and swiped.
Looking directly at the photos, the traces that Jiang Yuan said are too thin, so thin that you can't see them unless you look carefully.
Even with a horseshoe mirror, these scratches can only be seen. 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, recalled the traces he had just seen, and made a judgment secretly.
Trace identification can be used to identify 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, just one trace may not be specific, as if two people were holding a cane to pump the third person's buttocks, the canes are the same, and the individual traces drawn out are naturally similar.Although there may be a difference in depth and length, it is difficult to prove.
But if two people smoke more than a dozen times, or even more, to form a whip mark, then the whole whip mark will have a certain difference and specificity.
But needless to say, it is known that this identification method is less accurate, and the difficulty is several times higher.
"How do you think these traces are formed?" Zhang Xian was reminded by Jiang Yuan, and he basically agreed with [-]% of them. Both cars were stolen, and there were new traces. That means they were made by the same group. Because, there is a high probability.
"I judge that this driver has the habit of hammering cars. In addition, his right hand should be wearing something, a watch, most likely it is a Wenwan string, so these scratches were left on the right side." Jiang Yuan's hand was in the air Waved a few times.
Others didn't quite understand, but both Zhang Xian and Wu Xia understood that Jiang Yuan was simulating the driver's right hand waving.
The actions that Jiang Yuan simulated were exactly the actions caused by some scratches on both cars.
Also take the whip on the buttocks as an example, whether it is because of angry whipping or excited whipping, although the same person is on different people's buttocks, the whip marks drawn may look messy.
But if you analyze carefully, you will usually find that the welts on the two buttocks always have something in common.
On the premise of not deliberately changing the movements, a person's height, weight, and the movement of waving a whip will always have something in common, which can be regarded as part of muscle memory.
Jiang Yuan found the similar scratches on the two cars.
To use trace evidence of this level in court may require a little procedure and trouble.But at the investigative stage, it is enough to make a decision.
"I agree." 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 deliberately supported Jiang Yuan.As a technical expert listed by the ministries and commissions, Zhang Xian knows that some young technicians often encounter a crisis of trust.For example, Gao Changjiang, the director of the Guqi City Bureau, can only say that he partially trusts Jiang Yuan now.In fact, it's not easy, at least Gao Changjiang can listen to Jiang Yuan's opinion, but he doesn't seem to trust Crouching Dragon and Phoenix Young.
After Zhang Xian said "agree", the expression of Gao Changjiang next to him changed immediately, and he immediately looked at Wu Xia.
In terms of familiarity, the one he trusts the most is Wu Xia, an expert from the province.
Although, judging from the performance of the three of them, Wu Xia seemed to be a little inferior to Zhang Xian and Jiang Yuan, but in terms of trust, Gao Changjiang had seen Wu Xia show off his might.
After Zhang Xian and Jiang Yuan's dialogue, especially Jiang Yuan's explanation and gestures, Wu Xia also understood the traces on the photo, and was consulted by Gao Changjiang's expression, and said: "Jiang Yuan's words are quite reasonable."
Gao Changjiang did not hesitate any longer, and issued a series of orders:
"Check the license plates of these two cars, and call out the vehicle information. Pull out the case of the lost car and find surveillance. Lao Zhou, take a few people to the scene of the lost car and see if you can collect any images, ask Ask the merchants around you."
"Car rental company, isn't there a car from the car rental company? Zhu Hongbo, take someone to the car rental company, adjust the monitoring, and bring all the GPS data over to see where they went. Make a record for the people of the car rental company. Those who were looking for the car at that time brought them back and asked carefully."
"Don't move inside the car, just ask the scooter to be dragged to our garage, and let the trace inspector go up to scan fingerprints and DNA."
"That...Director Wang, I leave the image tracking to you. See if you can find the whereabouts of this group of people by passing through and stopping the vehicles along the way."
Gao Changjiang dispatched manpower easily and skillfully.
He is the chief of the bureau from the front line, and he has directed and solved a lot of cases, but the difficulty of this case is too high, and the criminals are planning Zhou Xiang to commit crimes, so it is not easy to solve it in a short time.However, it is also part of his ability that he can get the ministries and commissions to support experts and put them in place immediately.
Jiang Yuan only added one sentence: "The car has been delivered, and I will investigate."
His level 4 crime scene investigation skills, looking at Guqi City, he is also the top one.
For an expert like Zhang Xian, even if he has top-notch on-site survey skills, no matter how old he is, it's hard 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 vehicle is deeply cleaned, there is a high chance of leaving dander, hair, fine hair, saliva, nose hair, tingle hair, eyelashes, etc. in the car.
Jiang Yuan feels that this step may not be necessary, because the information that the vehicle can provide is very large. Even if several criminals use the method of stealing the car, the probability of being discovered has been reduced, but when the vehicle is identified, escape The probability has been greatly reduced.
This time, their follow-up crimes still left no clues.It doesn't matter if the vehicle is recovered by the car rental company.The car rental company lost a lot of cars, and the police would not investigate them without a reason.
However, the perpetrator's attempted crime in Daji in the countryside left too many clues, including this abandoned red Santana, which also became a breakthrough.And if they don't abandon the car, they will still face high risks, especially when the police can follow the cameras on the road. Convenience increases the difficulty of escape.
That is to say, the attempted abduction is not strictly pursued.
With the progress of the case, the members of the task force of the Guqi Municipal Bureau became excited, but Jiang Yuan calmed down beside him.
Soon, the first clue came.
"They bought the ID card they gave to the car rental company, but they used the same ID card to check in in Shidong. The ID card they checked in with them rented a car from another car rental company. GPS showed that the car was in motion. , on the highway...we are going to arrest people now." Gao Changjiang went out for a trip, and when he came back, he was full of murderous intent.
