Jiang Yuan sat on the chair, savoring the newly acquired skills carefully.
Unlike fingerprints, crime scene investigation is a basic skill that almost every policeman must master. It can be said that any policeman will be involved in crime scene investigation to a greater or lesser extent.
However, the skills in the criminal investigation direction all have one characteristic. Once you dig into the details, the difficulty and requirements will gradually increase.
For example, the spot investigation skills that ordinary police officers in a police station must master tend to be more small-scene and comprehensive. The spot investigation skills required by traffic police or criminal police are also significantly different. Spot investigation of large scenes often requires professional command, such as raids on telecommunications fraud.
In an office, the most difficult thing is how to secure the evidence before criminals destroy and hide it. For cases that occur in public places, the investigation faces even more challenges.
Theoretically, the on-site investigation should be like the scenes that appear in movies and TV shows. Professionals are equipped with professional equipment and conduct meticulous inspections of the scene. For example, marking the evidence one, two, three, four and five, planning the route to the scene in advance, and even
Lay transparent on-site survey treads to minimize the impact of surveyors on the site conditions.
But in reality, the police station that can afford professional field investigation and buy professional equipment almost has to start as a municipal bureau. It’s not just about the funds. The economic situation of some southern county bureaus may be good, but they only need to die.
There are not enough people, not enough major events happen, and even the most professional people cannot be improved and will either be transferred away or left useless.
In addition, for ordinary small cases, it is not easy to get other colleagues, including leaders, to cooperate with the requirements of the investigation.
Most of the field investigation skills that Jiang Yuan has mastered in the past were for forensic scenes. Common ones are homicide cases, such as personal injury cases. If you change the case type, there may be field investigation research specifically for illegal medical practice, etc. To talk about the level, only
It can be said to be an entry-level bag.
In Uncle Seventeen's case, what Jiang Yuan could do was very limited.
However, the newly acquired skills gave Jiang Yuan great confidence. Think about it, egg fried rice that is so delicious and economical is LV3. This LV4 crime scene investigation must be abalone and egg fried rice?
"What are you thinking about?" Wang Zhong touched Jiang Yuan, and then said: "I found such a case, do you think it's suitable?"
"Are they still from this county?" Jiang Yuan raised his head and asked first.
Forensic doctor Wu said happily: "Xiao Jiang can do it, he is starting to have a sense of ownership."
Wang Zhong sighed with envy: "After all, there is a reward of 10,000 yuan. To be honest, after working for so long, this is the first time I have seen people from the Criminal Division squadron get a reward. The last time, the director spoke about the backlog of murder cases.
I actually gave the criminal police 100,000 yuan."
As long as there are clues in the backlog of murder cases, the criminal police team and the county bureau are relatively active in following up. The most typical one is to squat in front of the fugitive's house on New Year's Eve, miserable but full of expectations.
Most of the backlogged cases are usually solved using this stupid method. For the criminal police in Ningtai County, technical means have always been just an auxiliary among auxiliaries.
Jiang Yuan actually doesn't care about ten thousand yuan. But he likes this sense of honor very much.
As a Jiangcun person, it is extremely difficult and lack of cost-effectiveness to increase your family's wealth with real skills. Maybe after struggling, the family land will be demolished. Especially when the father is from Jiangfu Town, this
Difficulties and lack of cost-effectiveness will lead to increased costs. The name "rich town" is no joke.
However, as a Jiangcun person, it is extremely difficult to gain a sense of honor. If you do something well, you will be accused of taking advantage of your family's wealth and status. If you do something particularly well, you will usually be considered to have used money.
But in schools and workplaces, simple rewards have become extremely precious.
"Let's talk about the case first. When the reward comes, I will cook fried rice for everyone." Jiang Yuan felt that money was not important, so he decided to cook fried rice himself as a reward for everyone.
Wang Zhong shook his head helplessly after hearing this, pulled out the case, and said, "See if this works."
Wang Zhong often scans the database, and is very concerned about cases that can be solved directly through fingerprints, or cases where fingerprints are key clues.
However, his abilities are limited, and the cases he can sweep out are also limited. Now that Jiang Yuan appears, he actually feels happy about getting a cheat.
Jiang Yuan glanced at the case roughly and said, "Is it a theft?"
"Don't look down on the theft case." Wang Zhong heard Jiang Yuan's tone and said: "This is a key case in our county. A group of people used a car modified with an oil storage tank in the highway service area.
, secretly extracting oil from passing trucks. Some of the people who called the police called the police in our county, and some in several nearby counties. It is considered a series of cases. If this case can be solved, it will be equivalent to solving a dozen cases in one go.
."
Jiang Yuan understood a little better now and said with a smile: "As a thief, if you don't catch him in action, you probably won't admit it."
"It must have been involved in at least several cases. Moreover, my guess is that the car they used was modified. It is definitely impossible to end the case just a few times. It is estimated that they may move around the country to commit crimes. Gang theft cases, and
Okay." Wang Zhong said a little guilty. He had some ideas when choosing this case because he had compared the fingerprints in this case for a long time and failed to match them in the end. On the one hand, he was a little bit
Unfortunately, on the other hand, he also wanted to see how Jiang Yuan compared and whether the comparison could be successful.
However, as he said, the cost-effectiveness of gang theft cases is relatively high.
Calculated according to the combat power rankings, a discovered theft case is worth about 0.1 points, which seems low, but if the concept of gang theft is added, the score can be doubled or even tripled. It is equivalent to solving a total of
Something like 0.2 or 0.3.
At the same time, gang theft means that the number of thefts is often more than one. If one case is solved, many cases will be solved. If you are lucky enough, it is possible to solve dozens of cases at once. In this way, the price/performance ratio is higher.
Going one step further, if criminal suspects are captured, each person can bring about 1 point of KPI. If the gang is large enough, it will also contribute.
Finally, units such as the Criminal Police Team have a clear number of solved cases in their annual assessment indicators. Generally speaking, a series of thefts are used to fill the gaps.
As for Jiang Yuan, he himself has no tendencies or goals. Whether it is a major case or not, it actually doesn't matter much.
After saying a few words casually, Jiang Yuan sat down naturally. From the many fingerprints involved in the case, he picked out 5 bow-shaped fingerprints and said: "This is what I am better at doing now. Others
It will not be processed for the time being."
"Then you do it first." Wang Zhong didn't know what was wrong with Jiang Yuan's only doing bow-shaped tattoos. He just thought it was a habit. He now opened his eyes wide, wanting to see more of Jiang Yuan's specific operations.
