In the next two days, Jiang Yuan and Liu Jinghui cooperated and used two more cases to train the police officers.
The purpose of the training is not to solve the case or something. It is actually to teach front-line police officers how to cooperate with criminal departments, photo investigation and other units, how to retain evidence, and how to expand to the maximum extent.
If infantry is used to describe front-line police officers, criminal department, image reconnaissance, technical reconnaissance and other units are equivalent to artillery, armored soldiers, bombing aviation...
Infantry is the basis of combat, it can be used for occupation and attack, it can be independently assigned to other troops, or it can be launched with attacks. However, as the scale of the war increases, infantry and artillery coordination, intra-tank coordination, and ground-air coordination are the effectiveness.
The highest.
For Jiang Yuan and Liu Jinghui now, or for the current Jiang Yuan Case Special Team and Taihe Working Group, a simple grassroots criminal police must also master various coordination techniques. Just mobile phone monitoring DNA must be
It is impossible to survive. At least, there must be complete trace collection, especially fingerprints, tools and footprints. Secondly, even if the level of plant spore powder is not collected, we know which evidence to keep and give a complete record.
It is also very important to maintain the options for forensic botany.
In addition, surveillance videos, especially the collection of private surveillance, are also the top priority. The latter often needs to cooperate with the iron foot of grassroots police officers. Only when there are more places to visit, ask more questions, and think more can they collect them.
Get enough surveillance videos.
Part of this training is skill training, and part of the training is actually practical demonstration.
Only when everyone sees the actual combat effectiveness will they be willing to collect corresponding evidence. Otherwise, if there is no one in the unit to solve the evidence, and Jiang Yuan does not help, then it is likely to be pure.
Waste. After all, not every unit has a criminal policeman like Pang Jidong who has a certain interest in this and is also able to invite corresponding professionals.
On the other hand, in the news released by Huang Qiangmin, this has also become a prerequisite under the one-price all-inclusive model.
Don’t be in a hurry when encountering a difficult case. It doesn’t matter if you can’t find Jiang Yuan for the time being. You can save the evidence first and organize your own task force to use traditional methods or intra-air artillery coordination and other tactics.
If the infra-cannon coordination cannot be overcome, the B and Tan coordination cannot be penetrated. At this time, call Jiang Yuan to have a set of ground-to-air coordination, then the evidence accumulated before will become a marker, which will help Jiang Yuan bombard the target.
Huang Qiangmin has been promoting this for a few days, and criminal police from all over the country feel that it is acceptable.
Nowadays, saving more types and quantities of evidence is the mainstream, such as evidence of plant spores. It sounds so high-quality, but it is actually to store clothes, bed sheets and other textiles of relevant personnel. The most troublesome step is to take photos and mark them.
, prove the source of clothing and ensure the integrity of the link of evidence.
If you want to say something wrong, you have to occupy one or two more lattices of the evidence cabinet. The overall expense may be the workload of a criminal department employee for two or three hours. It is absolutely acceptable for a case that is complex enough.
Early investment.
In contrast, collecting surveillance and various on-site traces consumes more time and energy. However, this is the mainstream requirement for investigating cases, that is, small cases at the police station level can be simplified and slightly
For cases with some intensity, such as burglary, at least several criminal department personnel need to collect trace fingerprint DNA.
It depends on the local area. In some large cities, such as Beijing and Shanghai, the grassroots police force is sufficient and the incidence rate is relatively low. In some jurisdictions, they have reached the point where the people lost two chickens and the police recovered them overnight.
In other cities, cases that cannot meet the standards for filing are really not available to deal with.
The reason for this is that ordinary people may not care much, but people who often commit crimes really care. Therefore, the reverse flow of criminals will further stimulate the vitality of the criminal market...
For example, in Ningtai County today, the county bureau itself cannot provide a sufficient case to entertain police officers from other places for training, which is somewhat of a bit inadequate.
So, on the last night of the training, Huang Qiangmin specially asked the cafeteria to make hot pot, wandered around, and said a lot to everyone.
Liu Jinghui and Jiang Yuan were at the same table, and had already left the sequence of being entertained and started playing the mystery game on their phone bored.
As long as Wei Shi didn't do math problems, he felt that life was enjoyable, but sat beside Liu Jinghui and watched him thinking hard, he said helplessly: "Liu Chu, I have so much brains to worry about in normal times, so I haven't rested yet
Is it?"
"I haven't been home lately, what's the point of thinking?" Liu Jinghui smiled and shook his head.
After he finished speaking, he saw that several people here looked at him with reasoning eyes.
Without thinking too much, Liu Jinghui could outline their mind map instantly.
"What I said was a brain-intensive thing, not what you thought." Liu Jinghui corrected.
Mu Zhiyang sat on the other side of Jiang Yuan, and laughed "haha" from the air: "Liu Chu is different, and it's all about getting home."
Wu Jundao put down his chopsticks and smiled muffled: "Liu Chu is a skilled person. It is best to use technology to do it with your brain..."
"No, no!" Liu Jinghui put down his mobile game and hurriedly said, "I will explain first that everything is normal. I mean, when I go home, you have to guess your wife's thoughts. That is a good place to practice reasoning, please understand."
People around them seemed to be smiling and pretended not to understand.
Wei Shi was the most scrupulous, teasing the old seniors as if they were teasing their brothers, saying, "No wonder Liu Chu's reasoning ability is second to none. Behind your success, there is also a powerful woman!"
Liu Jinghui could still accept this joke and said slowly: "Every success of mine is due to my wife, and there is no doubt about this..."
"I would be fine if you could lend your sister-in-law to everyone." Wei Shixiu cut off before Liu Jinghui could breathe evenly, saying, "If you lend your sister-in-law to everyone, at most, reasoning will be done in a few years.
It can take root and sprout in Shannan Province!"
"Jiang Yuan." Liu Jinghui turned his head and shouted: "Check out your apprentice!"
Jiang Yuan looked up and glanced at Shi Wei.
Wei Shiyi obediently patted his face with his hands and half-jokingly said, "Master, I was wrong. I am not big or small. Don't punish me for doing math problems. People are stupid."
Liu Jinghui could only smile helplessly.
Jiang Yuan was also looking at his phone. At this time, he clicked and sent two screenshots to Wei Shizhi, saying, "It just so happens that you can go to the capital and bring the gallery boss back. Chuanxing, you can arrange two people to follow him.
The guards are together.”
"Yes." Wang Chuanxing agreed.
Wei Shi asked: "Did the gallery owner steal it?"
"That's not. It has nothing to do with this case." Jiang Yuan paused and said, "I see that in the photos they took as evidence, there are at least three of the signature prints in the pictures, which is a problem. It's with the owner of this gallery.
The handwriting matches it, which means he has a fake price, so he has caught it by the way."
"Yes." Wei Shi immediately understood that this was an unlucky person.
"Go now." Jiang Yuan raised his chin: "Now we should be able to catch the night flight. When we arrive, we will catch people at night. It is best to bring them back tomorrow and hurry up and deal with them, so as not to look back and have another case. We will go back and have another case.
Go out."
"Uh...yes!" Wei Shi knew that this was a punishment.
Jiang Yuan then took out his cell phone and said, "I'll call Cui Qishan. He is the captain of the Fourth Brigade of the Criminal Police Detachment of Zhengguang District Branch. Just ask him to send two people to get people with you. Taozhi, turn around.
I'll send a message to say it."
"Yes." Wei Shiying said in secretly.
As Jiang Yuan said that, he edited the text message to Tao Lu first, and then looked for Cui Qishan from the address book.
Before the call was made, Tao Lu called over.
"Jiang Yuan, are you coming to the capital?" Tao Lu's words were filled with joy.
Jiang Yuan coughed twice, Yao glanced at Huang Qiangmin who was running all over the field, and said, "I plan to send someone over there, and I will come back if I catch the suspect..."
Chapter completed!
