Chapter 778 Actual Combat

Jiang Yuan, Cui Qishan, Liu Sheng, and five stray dogs shared a large pot of dog food and left with satisfaction.

Before leaving, the stray dogs nodded to Jiang Yuan, sniffed Cui Qishan and Liu Sheng, and then left the flowerbed in the center of the community with satisfaction and went to their familiar places.

"You Jiang family members are quite caring. Your father likes to cook for people, and you like to cook for dogs." Cui Qishan said and burped.

"I just occasionally do it to fulfill my wish." Jiang Yuan has received many bequests, but there have only been two bequests as strong as dog food.

One was from the prostitute Chen Manli, and the other was from the professor Zhou Xiangyang.

To a certain extent, Chen Manli's bequest is heavy and passionate. Therefore, Jiang Yuan will also make dog food when he is in a bad mood, just like Chen Manli. The process of feeding stray dogs is an extreme identity recognition as a member of the human race, and the police sometimes need this especially.

However, Jiang Yuan's frequency of feeding dogs was too low and too random. To stray dogs, Jiang Yuan might be more like a Santa Claus legend.

The next day.

Huang Qiangmin appeared at Jiang Yuan's door with pancakes, fried dough sticks and tofu pudding from the gate of Ningtai No. 1 Middle School.

Jiang Yuan and Jiang Fuzhen were both a little surprised.

Although Jiang Fuzhen often sent supplies from Ningtai, it was the first time he saw such a thoughtful way of sending supplies as Huang Qiangmin.

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

"I just happened to be coming to Beijing, so I brought some by the way." Huang Qiangmin smiled slightly, walked into the room, and said: "You guys eat it while it's hot, and give me some tea, and I still have work to do later."

"What work?" Jiang Yuan put all kinds of food on the table, and then took pancakes and tofu pudding for himself, quite excited.

Huang Qiangmin thought to himself, I came here specially, and the most important job is not to comfort you.

Of course, Huang Qiangmin did have a job.

Sitting next to Jiang Yuan, seeing Jiang Fuzhen happily taking tofu pudding and soy milk to the restaurant, Huang Qiangmin smiled apologetically and said, "I came to see the actual combat of a technical reconnaissance vehicle here."

"The technical reconnaissance vehicle of the Beijing Bureau?" Jiang Yuan scooped a mouthful of tofu pudding with chili oil. The smooth and tender taste and complex seasoning instantly awakened people's taste buds.

Foods that can be used for breakfast are the kings of taste in a place. Ordinary people usually eat one or two or two or three kinds of breakfast, but to eat the same or two kinds of food one by one and still feel delicious, this is a very high requirement for food.

From this point of view, Guangzhou, which eats porridge or rice noodle rolls for breakfast, Henan, which eats spicy soup, Guangxi and Hunan, which eat rice noodles, and Tianjin, which eats pancakes, are all regions with very unique food characteristics. The capital of Douzhi, which carries the banner of tradition, has somewhat given up treatment.

Huang Qiangmin sipped his tea and said, "Yes, they have just bought a batch of technical investigation vehicles, and they said they can allocate one to us, priced at 7 million."

"So expensive?" Jiang Yuan was surprised.

"It's worth at least five or six million. It's a good thing, and it's really expensive." Huang Qiangmin invited Jiang Yuan and said, "Let's go and have a look. If it's not worth it, we won't want it."

"Okay." Jiang Yuan ate faster.

Criminal Police Detachment.

The technical investigation of the Beijing Bureau had been communicating with the technical investigation of Ningtai County in a corner.

It is said that technical investigation is a family, and it is very easy to communicate with each other, and they have their own communication mode. As for how to communicate specifically, Jiang Yuan is not very clear.

Even for ordinary police, technical investigation is like a black box. They can only input questions and get results. The specific process inside is unknown.

Jiang Yuan was not curious, so he waited patiently.

Wu Junhao and Liu Wenkai in Beijing also came. A multi-million-dollar technical investigation vehicle, not to mention Ningtai County, Qinghe City doesn't have one either. Everyone wants to see it.

"Come on, Political Commissar Huang, Captain Jiang is here too, sit down, sit down first, and take a look at the case that Lao An picked for you." When Tao Lu arrived at the place, the exchange officially began.

After Tao Lu's introduction, An Xibing from the Equipment Department brought over a few files and placed them in front of Huang Qiangmin, Jiang Yuan and others, and said with a smile: "The case we picked today was just filed three days ago. Political Commissar Huang said he wanted to demonstrate it, so we asked colleagues from the technical investigation and criminal investigation to choose a case, and then we picked this one. After we picked it, we started to solve it on the same day..."

An Xibing's main purpose was to show that he didn't falsify, but it was inevitable to operate in advance. After he made it clear, he asked the police officers in charge of the case to come over and explain.

The police officer in charge of the case was a police officer from the Zhengguang Bureau. He came over and saluted, and then reported seriously:

"... This case is a burglary case... The perpetrators robbed six households overnight, all of which were residents of the same community and the same building. The stolen items included more than 40,000 yuan in cash, a total of 18 gold and silver jewelry, three mobile phones, an IPAD, a pair of women's stockings, and four pairs of men's sneakers, all of which were collectible AJ shoes. 57 figures, estimated at 80,000 yuan."

The police officer said this in one breath, paused, looked at Jiang Yuan and Tao Lu, and then said: "The on-site investigation of this case has been completed. The criminal entered the victim's house from the balcony by climbing the drainpipe. Considering that 6 households were robbed that night and the number of stolen items was relatively large, we guessed that the criminal should be a habitual offender, so first consider linking the cases..."

After the police officer handling the case finished explaining the situation of the case and the progress of the investigation, An Xibing stood up and smiled and said: "The case is basically clear. Next, we can discuss the direction of the investigation first."

Everyone smiled and said nothing, waiting peacefully for An Xibing to show off his skills. Only Jiang Yuan looked more seriously.

His character is inherently cautious. On the other hand, the greater the reputation of "Ningtai Jiangyuan", the more Jiang Yuan himself pays attention to his own influence.

This is what Huang Qiangmin has told many times. If, like others, Xiaoxiao just let the file go, and when people turn around and say, "This is the evidence that Jiang Yuan has seen," how should we explain it?

Of course, An Xibing couldn't really wait for Jiang Yuan to finish reading such a long file before inviting another policeman over.

"I'm a technical detective." The visitor smiled and said, "Let me tell you our solution."

He scanned the crowd and then looked at Jiang Yuan before continuing: "Normal burglary cases often rely on footprints and fingerprints to solve the case. It would be best if there is surveillance. There are footprints in this case, but there are no fingerprints or surveillance, so, We prioritize locking cell phone signals.”

The technical detective said: "We searched the mobile phone signals in advance, but we did not find a suitable suspect. The suspect should have been prepared and committed the crime after turning off the phone. So, we chose the reverse operation, choosing to turn off the phone after 10 pm and turn it on after 4 am. These mobile phone users are listed as suspects.”

"There were two people who did this within the area of ​​the base station where the crime occurred that day. One of them had a criminal record, and the other was a middle school student who got up secretly at night to play with his mobile phone. The surveillance at home proved that he was still doing homework at 12:30 p.m., so he was excluded. ”

"In this way, we conducted an in-depth investigation on the man with a criminal record and found that he was suspected of committing a major crime. The next step is to determine the specific location of the man. Traditionally, we may have many plans. Today, we choose to dispatch The technical investigation vehicle will come directly to find the location of the mobile phone used by the man. Everyone, please get in the vehicle."

After the technical detective finished speaking, he asked everyone to get into a Coaster, and he himself got into a van-style technical detective vehicle, accompanied by a police car, and a group of three vehicles were dispatched.

On Coaster, Wu Junhao praised: "It's quite vigorous and resolute."

"No, once a technical investigation vehicle is dispatched, it costs 10,000 yuan in some places." Huang Qiangmin was very envious.

"What ten thousand yuan?" Wu Junhao didn't understand.

"I bought a technical investigation vehicle in X, but I thought it was expensive. When the police from other places went there, if they wanted to use a technical investigation vehicle to find someone, they would pay 10,000 yuan at a time. People from all the capital and county towns would give it to them. It's a no-brainer." Huang Qiangmin sighed as he spoke: "I'm not as stubborn as them. Even if I buy a technical reconnaissance vehicle, I wouldn't dare to take it away. At most, it will be borrowed by people from other places."

"They collected too much. There are six chickens on this car." Liu Wenkai shook his head.

"The technical investigation vehicle is rented for one day." Huang Qiangmin glanced at Liu Wenkai: What are you talking about?

Liu Wenkai felt aggrieved: "I'm also talking about overnight stays."
