"How...how do we masturbate?" Wang Zhong stood next to Jiang Yuan very consciously.
After removing the fingerprints that have been matched, there are still more than a dozen fingerprints left, which must have been left by several people. This workload is also a big case for trace inspection.
"Do you remember this case?" Jiang Yuan asked first. Three years ago, Wang Zhong had already undergone a trace inspection. It was the only trace inspection conducted by the county bureau.
Wang Zhong shook his head and said: "I have no memory. It's not a special case. When we compare fingerprints, we don't necessarily look at the case. We can compare the fingerprints directly."
Wang Zhong is very much like the kind of student who passes the test. When the test score is far less than 60 points, he will work very hard, but when the test score is significantly higher than 60 points, he will give up easily. When it comes to matching fingerprints
Sometimes, it is best if you can match the fingerprints, and you are good at explaining yourself if you don't match.
Jiang Yuan didn't need to worry about these. He found a notebook to record, and then said: "Let's classify the fingerprints here first to see how many people they belong to, and then select the appropriate ones for matching."
"Okay, then record it according to the photo number?" Wang Zhong also took a notebook and sat next to it.
Jiang Yuan responded, then focused his attention on the fingerprints. From time to time, he stretched out his hand and compared it over and over.
Most of the fingerprints on the bicycle appear in pairs. In addition to the fingerprints of the owner Ding Lan, there are also multiple pairs of fingerprints that appear on the front, longitudinal beams and under the seat.
Deducing the scene of the crime, we can imagine that these fingerprints were probably left by someone or a few people when they abandoned the car. Maybe they can also judge the situation at that time.
However, this reasoning only circulated in Jiang Yuan's mind.
Jiang Yuan is not only a newcomer, he is not a criminal investigation professional. He has neither experience nor knowledge about investigation, reasoning, and case solving.
In contrast, almost all of the young policemen in the various squadrons of the Criminal Police Force have a professional background. Even the younger generation of auxiliary policemen are mostly from police schools in the province. They often take the public examination while working, waiting for the opportunity to go ashore.
And once you get the establishment, you will have immediate combat power.
The municipal bureaus and provincial departments on the next level have many graduates from the People's Public Security University and the Criminal Police College - these are the top two universities in the police field. The graduates are in the upper class in terms of IQ, physical fitness, technology and knowledge, but
When you enter the work unit, you must follow the steps of the veteran police officers and learn from them.
Jiang Yuan, a newcomer majoring in forensic medicine at a medical university, does not feel that he is more Sherlock Holmes than his colleagues.
Without a heavenly forensic system, Jiang Yuan would probably have to sit in the office waiting for the body, or do odd jobs with the criminal police team, or do some injury assessment work with Wu Jun.
However, with the system, Jiang Yuan's situation is completely different.
However, he also just wants to make good use of his existing advantages.
To use the thinking of the famous Comrade Zeng Guofan, it is the fastest shortcut for junior players to stick to their guns and fight stupidly.
Jiang Yuan didn't even try to identify whose fingerprints might belong to them. He just sorted them into categories, compiled them in order, and then matched them one by one.
At the end of the day, Jiang Yuan had only completed three sets of nine fingerprints.
The difficulty of fingerprints is not high. It is also the fingerprints left on cylindrical metal and the fingerprints left on bicycles, which is about the level of LV2.
Comparing the Liu Yu injury case, that is, the injury case caused by a student's party after the college entrance examination, the fingerprints left on the stool were at least a strong LV3 level.
However, Liu Yu's injury case involved serious injuries and involved college entrance examinations, teenagers, etc., so it involved experts at the provincial and municipal levels. It was not possible to detect it at the time because the fingerprints were too incomplete.
This time, Ding Lan's disappearance case is completely different from the same dimension.
This case, at best, received the attention of Comrade Wei Zhenguo, deputy captain of the Sixth Squadron, but it never received good support at the technical level.
For Jiang Yuan, unless there is no corresponding fingerprint in the library, matching is not difficult. He did it slowly, mainly because the fingerprint on the cylinder was too deformed, and it took more time to adjust.
"Jiang Yuan, are you going back?" Wang Zhong came into the office again and asked curiously: "How many fingerprints did you win?"
"Three people." Jiang Yuan had processed nine fingerprints, belonging to three people. They were all colleagues of the victim Ding Lan.
"Awesome." Wang Zhong was a little embarrassed. Theoretically, these fingerprints should have been matched by him before, but he couldn't match them. Jiang Yuan spent half an afternoon making so many of them, so he could only
It proves that the gap in strength between the two is really quite big.
Jiang Yuan smiled modestly: "Good luck."
Wang Zhong shook his head and then extended an invitation: "Let's have dinner together tonight. You've been here for so long and we haven't had a good chat together yet."
"How many people?" Jiang Yuan agreed readily.
"I called a few people around the same age. Would you like to call Wei Yin?" Wang Zhong winked.
Jiang Yuan laughed: "Captain Wei's daughter? I don't even have contact information."
"Wei Yin's phone number is in the internal contact book. You can also add WeChat to the large group." Wang Zhong encouraged.
"Okay." Jiang Yuan smiled, turned on his phone, found the WeChat group, searched for Wei Yin and chose to add friends.
Wang Zhong couldn't help but be stunned when he saw Jiang Yuan's smooth operation.
In a group of bachelors, similar teasing and instigation often end with the teaser admitting that he is a coward. Wang Zhong did not expect that Jiang Yuan was not cowardly at all.
What Wang Zhong didn't expect was that in just a few minutes, Wei Yin on the other side had already approved Jiang Yuan's application.
Looking at Jiang Yuan's relaxed typing, Wang Zhong fell into confusion - is the school I went to inappropriate?
