"Hello, which unit are you from? Do you have an ID? Please show it to me."
Wang Chuanxing got up early in the morning with dark circles under his eyes. He stood at the door of Building 10 and began to register the visitors.
Hanging on the door of Building 9 are signs that read "Taihe Working Group" and "Jiangyuan Backlog Cases Special Team", and Building 10 is the auditorium that was newly built this year. In Huang Qiangmin's words, it is at a level that can be used to hold a meeting of heroes and model students in the county.
After the completion of Building 10, it was basically used for meetings and training sessions. This time, Jiang Yuan decided to start a class, and Huang Qiangmin immediately arranged it here.
In addition to Building 10, the Ningtai County Bureau Guesthouse was also expanded and renovated, which was just the right place to accommodate the police officers who came to study.
The hardware conditions were complete, and Wang Chuanxing and others arranged the course of the study class automatically and consciously without Jiang Yuan's instructions.
When it comes to organizing activities, Xu Taining's style of investigation is the most challenging.
If there are some mistakes in ordinary meetings and trainings, as long as the parties involved don't care and just laugh it off, the matter will be forgotten. However, the investigation will not tolerate this. Once a problem occurs, the participants themselves will not know how to make up for it.
This is similar to flood relief and dike building. The individualism in American movies cannot understand Chinese collectivism because they lack similar experience and do not understand that some mistakes cannot be taken responsibility by individuals, so they must be held responsible.
But for the police officers who have participated in Xu Taining's style inspections many times, organizing an event is too easy.
Even though the number and range of visitors far exceeded expectations, Wang Chuanxing and others still managed everything in an orderly manner.
Only when he was free did he call Huang Qiangmin to complain: "A group from Pingzhou came. It should be organized by their provincial department. One or two people came from each prefecture-level city. They said they would solve the accommodation problem themselves, so I gave them tickets for the buffet."
"I understand." Huang Qiangmin's voice was very steady, as if it came from underwater.
Wang Chuanxing said with a sense of ownership: "There must be about 20 people. It will probably be a bit troublesome to arrange their positions later."
"A shop doesn't need to be afraid of big-bellied people." Huang Qiangmin said in a muffled voice, "By the way, the people from the Chiyong City Bureau who came earlier have been finalized. If they have any subsequent requirements, you can just arrange them directly, write down the matters clearly, and ask them to sign."
"I understand. We can sign the contract now." Wang Chuanxing agreed.
Huang Qiangmin coughed twice and said, "Don't be so blunt. The experience is enough and it doesn't take much effort."
"Yes." After Wang Chuanxing finished his phone call with Huang Qiangmin, he continued to stand guard and handle various procedures for the guests.
Although they came to Ningtai County to study, the criminal police who could afford the travel expenses and could be sent by their units were at least "police officers" from all over the place. They were local tycoons that they might not be able to find when they went to other places to do business. Since they were attracted here this time, they had to be arranged pretty much the same way.
All the criminal police in the world are one family. You can't just be one family when you go to someone else's house - Little Joseph.
Inside Building 10, everything was arranged to the standards for a meeting. A group of interns prepared tea and snacks for the bosses, and then stood in the corner of the auditorium, looking at the stage with anticipation as if they were listening to secrets.
Jiang Yuan was still chatting with the guests at this time.
On the temporary podium, there were piles of case files, all of which were minor cases that had occurred in Ningtai County recently. Jiang Yuan had moved them all over to use as teaching aids.
The police officers who came to participate in the training were all knowledgeable. Just by flipping through it, they knew that it was brought in according to the time.
With so many cases that have not been solved, it cannot be said that there is no screening at all, but it is basically the same as no screening.
As we all know, small cases are not necessarily easy to solve, and some are quite difficult to solve.
Because there are too few traces left.
The fact that Jiang Yuan dares to pile up so many cases here speaks volumes.
However, criminal police all have a tendency to not believe in evil. Even if the evidence is right in front of them, they will still examine the source and authenticity of the evidence. When Jiang Yuan brought out a bunch of cases, naturally some people would try to test him.
Jiang Yuan answered casually, and by the way he gained a corresponding understanding of everyone's level.
Since a study class has been opened, it must be able to help people learn effectively, otherwise, he would be wasting his time.
Different people will have different views on the case, and the angles of investigation are even more bizarre.
Generally speaking, ordinary criminal police will use one or two, or at most two or three methods to solve the case. The classic ones, such as the cowboy sheriffs in some American movies, mostly just take a casual look at the scene, and then look for people based on the motive and method of the case. The more brutal ones can also use physical interrogation to obtain information.
In various provinces and cities in China, the techniques and models used by the police also have different focuses. This is related to the local police's case handling habits and local case handling conditions.
Just like the police in Shannan Province and Luojin City can try forensic botany, even if other places have such ideas, it is basically impossible to realize them. Unless they are at their last resort, they will not use such a plan.
This regional difference is often one of the reasons why criminals who commit crimes on the move are caught. It is like a lock that is moved around among many keys and will eventually be opened.
Jiang Yuan chatted with the police officers from other places while waiting for time.
When the watch reached 9 o'clock, Jiang Yuan stood up and said, "Let's get started. I sent some information in the group before, and everyone should have seen it. We will explain it with practical cases. The case we are investigating now is the theft case in Sunshine Supermarket. The case itself is very small, and the loss of stolen property does not exceed 5000 yuan. In fact, it is only about 3000 yuan. But the interesting point of this case is that the criminal took a towel at the scene, which gives us a place to use forensic botany."
Jiang Yuan waved his hand, and Wang Chuanxing, who had returned to his post, immediately played the PPT he had prepared last night.
The first few pages were a detailed description of the case. Jiang Yuan operated the remote control without mercy and swiped through them, directly coming to the photos under the electron microscope.
The pollen and spores, as small as a millimeter, appeared upright and in front of everyone.
Jiang Yuan coughed twice and said, "Let me tell you about some basic principles of our forensic botany. Taking this as an example, distinguishing the types of pollen and spores and then counting them is the most basic. The first step... judging the living environment of these plants based on the pollen is the second step... The third step is the most difficult, which is to determine the location of these plants based on the pollen map."
Jiang Yuan looked back at everyone who was listening attentively, then nodded and said, "These steps are actually similar to DNA and footprint identification. Sometimes it requires skills, sometimes it requires a little luck, and sometimes it requires running a lot... Of course, it is also important to control the position well. For example, in Ningtai County and Qinghe City, we have done a lot of preparatory work in forensic botany..."
"Oh, yes, Ningtai County has already made a plant map, right?" someone reacted.
"Yes." Jiang Yuan nodded. This was the cost of a whole building and could be used as a benchmark.
"So..." A detective here changed the subject: "What did that towel wipe? Can't we take DNA?"
"The criminal should have used it to wipe his clothes and shoes, so there are no sweat stains." Jiang Yuan explained.
"That's fine..."
Jiang Yuan waved his hand: "Let's start with the first solution. There's no need to find so many routes. Now, I'll teach you how to preserve and protect forensic botany evidence..."
He didn't plan to spend too much time on forensic botany, so he finished this step at about 10 o'clock, and then completed the matching on the map by himself.
This is a specialized thing and you can't expect to teach others in a few days.
After everything was done, Jiang Yuan took out the map of Ningtai County, zoomed in, drew a circle on the scene with a laser pen, and said, "The criminal should have stayed in this area for a long time. Next, we need to conduct a field investigation. Well, our police have already gone there. Let's change a plan now..."
"Change the plan?"
"What's the alternative?"
"Solving the same case twice?"
The detectives at the scene were a little confused and started talking about it.
Jiang Yuan coughed twice: "Because this is the first case of the day, and relevant evidence happened to be delivered, we will solve it twice first, just in time to make a comparison, so that there will be no waste in the future. We will strive for one plan and one solution. Well, we will borrow the tool traces in the second round..."
"Isn't that a footprint?" Someone who was familiar with Jiang Yuan's handling style couldn't help but shout out.
"As for the footprints, everyone is familiar with them. Do we need to do it again?" Jiang Yuan hesitated.
"Let's compare them." Those who were watching the fun just thought it was fun.
