National Forensic Doctor

Chapter 1211 Just in Time...

In the next two days, Jiang Yuan worked with Liu Jinghui and gave two more cases for the police officers who came for training to practice.

The purpose of the training is not to solve cases or anything like that, but to teach front-line police officers how to cooperate with criminal justice, image investigation and other units, how to preserve evidence, and how to expand the scope to the maximum extent possible.

If we use infantry to describe the frontline police, then the criminal investigation, image investigation, technical investigation and other units are equivalent to artillery, armored troops, bombing aviation...

Infantry is the foundation of combat. It can be used for both occupation and offense. It can be assigned independently or cooperate with other arms to launch attacks. However, as the scale of war increases, infantry-artillery coordination, infantry-tank coordination, and ground-to-air coordination are the most effective.

For Jiang Yuan and Liu Jinghui, or for the Jiang Yuan backlog case team and the Taihe working group, even the grassroots criminal police must master various cooperation techniques. It is definitely not enough to just monitor DNA on a mobile phone. At the very least, there must be complete trace collection, especially fingerprints, tools and footprints. Secondly, even if the level of plant spores and pollen cannot be collected, it is also very important to know which evidence to preserve and give complete records, so as to retain the option of forensic botany.

In addition, the collection of surveillance videos, especially civilian surveillance, is also a top priority. The latter often requires the cooperation of grassroots police officers. Only by visiting more places, asking more questions, and thinking more can we collect enough surveillance videos.

Part of this training is skills training, and the other part is actually a practical demonstration.

Only when everyone sees the actual effectiveness will they be willing to take the trouble to collect the relevant evidence. Otherwise, if no one in the unit can solve the evidence such as plant spores and pollen, and Jiang Yuan doesn't help, then collecting it may be a 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 relevant professionals.

It depends on the place. In some large cities, such as Beijing and Shanghai, the police force is well-equipped and the crime rate is relatively low. In some areas, if a citizen loses two chickens, the police will find them overnight. In other cities, there is really no time to deal with cases that do not meet the filing standards.

Ordinary people may not care much about the reason, but people who often commit crimes really care about it. Therefore, the reverse flow of criminals will further stimulate the vitality of the criminal market...

For example, in Ningtai County now, the county bureau itself cannot come up with a case of sufficient quality to entertain the police officers from other places who come for training, which seems to be a bit of a poor hospitality.

So, on the last night of the training, Huang Qiangmin asked the canteen to prepare hot pot, walked around the venue, and talked a lot to everyone.

Liu Jinghui and Jiang Yuan were at the same table. They were no longer in the process of being entertained and were playing reasoning games on their phones out of boredom.

Wei Shijian felt that life was enjoyable as long as he didn't have to do math problems. But when he sat next to Liu Jinghui and watched him thinking hard, he said helplessly, "Director Liu, you spend so much time thinking, why don't you take a break?"

"I haven't been home recently, so it's no use worrying about it." Liu Jinghui smiled and shook his head.

After he finished speaking, he saw several people here looking at him with reasoning eyes.

Without thinking too much, Liu Jinghui can outline their mind map in an instant.

"I meant it requires a lot of thought, not what you think." Liu Jinghui corrected.

Mu Zhiyang sat on the other side of Jiang Yuan and laughed four times from a distance: "Director Liu is different. It's a headache to go home."

Wu Junhao put down his chopsticks and laughed: "Director Liu is a technician. It's normal for him to use technology and think hard..."

"No, no!" Liu Jinghui put down the game on his phone and said quickly, "Let me make it clear that I am fine. I mean, when I go home, I have to guess what my wife is thinking. That's a good place to practice reasoning, understand?"

The people around him smiled and pretended not to understand.

Wei Shijian was the most unscrupulous. He teased the old senior as if he was teasing a brother, saying: "No wonder Director Liu's reasoning ability is second to none. There is also a powerful woman behind your success!"

Liu Jinghui could still accept this teasing, and said with a sigh: "Every success of mine is due to my wife, there is no doubt about that..."

"It would be great if you could lend your sister-in-law to everyone." Without waiting for Liu Jinghui to catch his breath, Wei Shijian interrupted him and said, "If you lend your sister-in-law to everyone, in a few years at most, the science of reasoning will take root in Shannan Province!"

"Jiang Yuan." Liu Jinghui turned around and shouted, "Take care of your disciple!"

Jiang Yuan looked up and glanced at Wei Shijian.

Master Wei patted his face obediently and said half-jokingly, "Master, I was wrong. I was disrespectful. Please don't punish me with math problems. I'm stupid."

Liu Jinghui could only smile helplessly.

Jiang Yuan was also looking at his phone. He clicked on it and sent two screenshots to Wei Shixun, saying, "It's just right. You can go to Beijing and bring the gallery owner back. Chuanxing, arrange for two people to go with Wei Shixun."

"Yes." Wang Chuanxing agreed.

Wei Shixun asked: "Did the gallery owner steal from the gallery?"

"No, it has nothing to do with this case." Jiang Yuan paused, then continued, "I saw that among the photos they took as evidence, there were problems with the signature prints on at least three paintings. They matched the handwriting of the gallery owner, which means he had faked the selling price. Let's just catch him."

"Yes." Wei Shixun immediately understood that this was an unlucky person.

"Let's go now." Jiang Yuan raised his chin: "We should be able to catch the evening flight now. When we get there, we can arrest the person at night. It would be best if we bring him back tomorrow and deal with him as soon as possible, otherwise we will be caught again if there is another case later."

"Uh... yes!" Wei Shixun knew that this was a punishment.

Jiang Yuan then took out his cell phone and said, "I'll call Cui Qishan, the captain of the Fourth Brigade of the Criminal Police Brigade of the Zhengguang District Police Station, and ask him to send two people to go with you to arrest the person. As for Tao Zhi, I'll send a message later."

"Yes." Wei Shixun secretly clicked his tongue twice.

Jiang Yuan edited a text message to Tao Lu first, and then looked for Cui Qishan in the address book.

Before the call was made, Tao Lu called.

"Jiang Yuan, are you coming to Beijing?" Tao Lu's words were filled with joy.

Jiang Yuan coughed twice, glanced at Huang Qiangmin who was running around the field, and said, "I planned to send someone over there to catch the suspect and then come back..."

"A plane crashed from our flight school. Can you help take a look?" Tao Lu said, emphasizing, "The forensic doctor said it's very difficult!"
