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 LV2.8 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, there are traces that he can't make that are normal, so why can't he understand them?
Next door, Zhang Xian, an expert on Zhen·LV4.8·Ministry and Commission Name·Trace Inspection who was also looking at the photos, slid over.
He noticed Wu Xia's expression. The detectives were all old and clever, and their ability to read people's expressions was as if they had stayed at a relative's house for 30 years. He immediately looked at a few pictures on the table.
photo.
"Are there the same traces?" Wu Xia asked directly.
Zhang Xian, who is a national-level figure in the name of 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 the horse hoof glasses, then 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 caused by dirt and scratches on the plastic. They are vertical, horizontal, and zigzag. It can be said to be a mess.
Zhang Xian studied the scratches very hard. In this kind of situation, everyone with a name has a name. He would never make fun of his own reputation in such a semi-public situation.
In fact, when the three of them gathered together, it was already a bit like an expert consultation. What each person said may be the basis for discussion at other people's dinner tables in the future.
There was no trace of panic on Jiang Yuan's young face, and he said calmly: "There are certain similar patterns here on the dashboard, on the armrest box, including the scratches on the steering wheel."
Jiang Yuan pointed at the photo and swiped.
Looking directly at the photos, the traces mentioned by Jiang Yuan are too thin, so thin that they cannot be seen without looking carefully.
Even with the magnification of a horseshoe mirror, these scratches can only be said to be visible. To say that they are the same, or that they come from the same person, is somewhat reluctant.
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 about identifying the similarity of a certain trace, but the formation of a certain trace can also be used as a template for identification.
This kind of trace may not be specific in isolation, just 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 it may
There is a difference in depth and length, but 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 on his right hand, a watch, most likely a pendant, so he left these scratches 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 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 whipping on the buttocks. Whether it is whipped out of anger or 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 movements, 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.
This level of trace evidence may require a little bit of procedure and trouble to be used in court. But in the investigation stage, it is 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 deep enough, so he specifically supported Jiang Yuan. As a technical expert listed in the ministry, Zhang Xian knew that some young technicians often encountered a crisis of trust. For example, Gao Changjiang, the director of the Guqi Municipal Bureau, now only
It can be said that he partially trusted Jiang Yuan. In fact, it was not easy. At least Gao Changjiang could listen to Jiang Yuan's opinions, but it was just not like he trusted Wolong Phoenix.
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 pull out the vehicle information. Pull out the case of the missing car and ask for surveillance. Lao Zhou, can you take a few people to the scene of the missing car to see if you can collect any images?
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 data to see where they have gone. Make notes for the people at the car rental company,
Those who were looking for the car at that time brought them back and asked them 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 car for 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 deployed 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 planned the crime carefully. It is not easy to solve it in a short time. However, he can win
Letting ministries and commissions support experts and arrive immediately is part of the capability.
Jiang Yuan only added: "The car has been delivered, I will investigate."
His LV4 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 for him 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 hair, 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 method of stealing the car, which has reduced the probability of being discovered, when the vehicle is identified, they can escape
The probability has been greatly reduced.
This time, their subsequent crimes actually left no clues. Even if the car was repossessed by the car rental company, it didn't matter. Car rental companies lost a lot of cars, and the police wouldn't investigate them without a reason.
However, the criminals' attempted crimes in the countryside left too many clues, including the abandoned red Santana, which also became a breakthrough point. If they did not abandon the car, they would still face high risks, especially in the
If the police can follow the cameras on the road, it will be difficult for them to drive the car back to their residence, and it will be inconvenient to find a place to park, which makes escape more difficult.
In other words, the pursuit of attempted abduction is not strict.
As the case progressed, the members of the Guqi Municipal 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 filled with murderous intent.
