Chapter 755: Practical Combat

Jiang Yuan, Cui Qishan, and Liu Cheng, as well as five stray dogs, shared a large pot of dog food, each satisfied and dispersed.

Before leaving, the stray dogs nodded to Jiang Yuan, smelled the smell of Cui Qishan and Liu Cheng again, and then satisfiedly walked out of the flower bed in the center of the residential area, each wandering to a familiar place.

"You Jiang family members are quite loving, your dad likes to cook for people, you like to cook for dogs." Cui Qishan said and hiccuped.

"I just do it very occasionally, it counts as fulfilling a wish." Jiang Yuan has obtained many legacies, but legacies as strong as dog food, so far there have been only two.

One came from the prostitute Chen Manli, and one came from Professor Zhou Xiangyang.

To a certain extent, Chen Manli's legacy is heavy and enthusiastic. Therefore, Jiang Yuan will also do dog food when his mood is not good, like Chen Manli. The process of feeding stray dogs is an extreme identity recognition of being a member of humans, and police, sometimes, especially need this.

It's just that Jiang Yuan's frequency of feeding dog food is too low and too random. To stray dogs, Jiang Yuan might be more like a Santa Claus-style legend.

The next day.

Huang Qiangmin appeared at the door of Jiang Yuan's house, carrying scallion pancakes, fried dough sticks, and tofu brain from the entrance of Ningtai No. 1 Middle School.

Jiang Yuan and Jiangfuzhen were both pleasantly surprised.

Although Jiangfuzhen often sent supplies from Ningtai, this was the first time he had seen Huang Qiangmin send them so thoughtfully.

Huang Qiangmin smiled triumphantly. He learned this trick from a certain entrepreneur.

"Just happened to come to Beijing, so I brought some along." Huang Qiangmin smiled slightly, entered the room, and said: "You guys eat while it's hot, just drink some tea, there is work later."

"What work?" Jiang Yuan put various foods in front of the table, and then took scallion pancakes and tofu brain for himself, quite excited.

Huang Qiangmin thought, I came here specifically, isn't the most important work to appease you.

Of course, Huang Qiangmin did indeed have work to do.

Sitting beside Jiang Yuan, seeing Jiangfuzhen happily taking tofu brain and soy milk to the restaurant, Huang Qiangmin smiled apologetically, and added: "I came to see the practical combat of a technical investigation vehicle here."

"Beijing Bureau's technical investigation vehicle?" Jiang Yuan scooped a mouthful of tofu brain with chili oil, the smooth and tender taste, and the complex seasoning made people's taste buds wake up instantly.

Foods that can be eaten for breakfast are the taste kings of a place. Ordinary people eat breakfast, usually just one or two, two or three kinds, and having to eat the same one or two kinds of food mouthful by mouthful, and still feeling delicious, this has quite high requirements for food.

From this point of view, Guangzhou, which eats porridge or rice noodle rolls for breakfast, Henan with spicy soup, Guangxi and Hunan with rice noodles, Tianjin with scallion pancakes, all have quite food characteristics, and Beijing with traditional big flag soy juice, somewhat gave up treatment.

Huang Qiangmin drank tea while slurping, and said: "Right, they got a new batch of technical investigation vehicles, said they can spare one for us, priced at 7 million."

"So expensive?" Jiang Yuan was surprised.

"At least worth five. Things are good things, expensive is also really expensive." Huang Qiangmin said while inviting Jiang Yuan, and said: "Let's go see it together, if it's not worth it, we won't want it."

"Good." Jiang Yuan ate a bit faster.

Criminal Police Detachment.

Early on, the technical investigation of the Beijing Bureau was communicating with the technical investigation of Ningtai County in the corner.

It is said that technical investigation in the world is a family, and technical investigation is very good at communicating, and they also have their own communication mode. As for how exactly they communicate, Jiang Yuan is not very clear.

Even for ordinary police, technical investigation is like a black box, usually only able to input questions, get results, and the specific process inside is impossible to know.

Jiang Yuan is actually not curious either, just waiting patiently.

Just when Wu Junhao and Liu Wenkai from Beijing also came over. Technical investigation vehicles worth several million, let alone Ningtai County, Qinghe City also doesn't have them. Everyone wants to see it.

"Come come come, Political Huang Zhengwei, Captain Jiang is also here, sit, sit first, look at the case Old An picked for you." Tao Lu arrived, and the communication officially began.

Through Tao Lu's introduction, An Xibing from the Equipment Section took a few files and put them in front of Huang Qiangmin and Jiang Yuan, smiling: "The case picked today was filed three days ago. Political Huang Zhengwei said he wanted to demonstrate, so we asked the technical investigation and criminal investigation colleagues to pick a case, and then picked this one, and after picking it, started the investigation on the same day..."

An Xibing mainly wanted to explain that he didn't fake it, but advance operation was inevitable. After he explained clearly, he invited the case-handling police to explain.

The case-handling police were the police officers of the Zhengguang Bureau. They came over and saluted, and reported seriously:

"... This case is a residential burglary case... The perpetrators stole from six households overnight, all of whom were residents in the same building in the same community. The stolen items included more than 40,000 yuan in cash, a total of 18 pieces of gold and silver jewelry, and three mobile phones. One IPAD. One pair of women's stockings. Four pairs of men's sports shoes, all of which are AJ shoe styles collected. 57 hand-made figures, estimated at 80,000 yuan."

The police officer said this in one breath, paused, looked at Jiang Yuan and Tao Lu, and added: "The on-site investigation of this case has been completed. The perpetrator climbed the drainage pipe and entered from the balcony. Considering that 6 households were stolen overnight, and the number of stolen items was quite large, we guessed that the perpetrator should be a repeat offender, so, first consider serial cases..."

After the case-handling police explained the situation of the case and the investigation progress, An Xibing stood up and smiled, saying: "This case is basically clear. Next, we can discuss the investigation direction first."

Everyone laughed and didn't make a sound, waiting for An Xibing to show off his skills. Only Jiang Yuan looked quite seriously.

His personality is originally relatively cautious. On the other hand, the bigger the name of "Ningtai Jiang Yuan", the more Jiang Yuan himself pays attention to his own influence.

This is also what Huang Qiangmin has repeatedly urged. If it were like others, laughing and putting the file over, when people say "this is the evidence Jiang Yuan looked at" in the future, how should it be explained?

An Xibing naturally couldn't wait for Jiang Yuan to finish reading such a long file, and invited another police officer over.

"I am from technical investigation." The person smiled and said: "Let me talk about our solution."

He scanned everyone, looked at Jiang Yuan again, and continued: "Residential burglary cases often borrow footprints and fingerprints to solve the case. If there is monitoring, it is best. This case has footprints, no fingerprints and monitoring, so, we prioritize choosing to lock the mobile phone signal."

Technical investigation said: "Early retrieval of mobile phone signals, we did not find suitable suspects, suspecting that the perpetrator should be prepared and turned off the phone before committing the crime. Thus, we chose reverse operation, choosing mobile phone users who turned off the phone after 10 pm and turned on the phone after 4 am, listed as suspects."

"Within the base station range of the case, there were two people with this operation that day. One of them had a criminal record, and the other was a middle school student who secretly got up to play with his mobile phone at night. Home monitoring proved that he was still doing homework at 12:30 am, so he was excluded."

"In this way, we conducted an in-depth investigation into the man with a criminal record and found that he had a major suspicion of committing the crime. Next, it was to determine the specific location of the man. Traditionally, we might have many kinds of plans. Today, we choose to dispatch a technical investigation vehicle to directly find the location of the mobile phone used by the man. Everyone get on the car."

After the technical investigation finished speaking, he greeted everyone to get on a Coaster, and he himself got on a van-style technical investigation vehicle, accompanied by a police car, and the three cars set off.

On the Coaster, Wu Junhao praised: "Quite vigorous."

"That's not it, a technical investigation vehicle is dispatched once, and some places cost 10,000 yuan." Huang Qiangmin was very envious.

"What 10,000 yuan?" Wu Junhao didn't understand.

"Just X place, bought a technical investigation vehicle, also felt expensive, police from other places went there, if they wanted to use the technical investigation vehicle to find someone, it cost 10,000 once, Beijing and county towns have to pay, no deception for children and old people." Huang Qiangmin sighed: "I am not as tough as them, even if I bought a technical investigation vehicle, I wouldn't dare to collect it, at most lend it to people from other places."

"They collect too much, this car is worth 6 chickens." Liu Wenkai shook his head.

"Technical investigation vehicle lending is for one day." Huang Qiangmin's eyes glanced at Liu Wenkai: What are you talking about?

Liu Wenkai was aggrieved: "What I said is also overnight." ===== CHAPTER 756 =====
