Chapter 576 Red, Yellow and Blue

Tang Xiaobo waited until noon, but Jiang Yuan didn't show up. He continued to wait patiently until the evening, and then waited until eight o'clock in the evening. The cafeteria lady was tired.

The cafeteria lady was not much older than Tang Xiaobo. She pulled her apron and said, "My husband is waiting for me to go back and watch TV series. If you want to cook, do it yourself in the evening. I will wash the dishes tomorrow morning."

Tang Xiaobo got up helplessly and said, "I'm sorry, there are special circumstances today, and I delayed your get off work."

"It's not a big deal. You officials are also very hard, but I can't wait any longer." The lady waved her hand and rode her electric car back without any courtesy.

Tang Xiaobo had no choice but to call his wife Wang Xiuyun to come to the rescue.

Not long after, Wang Xiuyun arrived. As usual, she scolded Tang Xiaobo first, and then said: "Instead of asking me to come over to cook, you might as well invite people to your home for dinner. Didn't you always invite colleagues home for dinner before? It's more intimate."

Surrounded by his confidants, Tang Xiaobo just sighed and said: "It's not good to appear so close."

"Then why did you ask me to cook?"

"It's not good to appear too cold." Tang Xiaobo sighed again.

Wang Xiuyun looked at her husband and shook her head and said: "Your job as director is more uncomfortable than raising pigs. You are afraid that the pigs will have diarrhea if they eat too much, and you are afraid that the pigs will lose weight if they eat too little..."

Tang Xiaobo thought about Chai Tong, and then thought about Huang Qiangmin. He was about to cry because of what his wife said.

Wang Xiuyun went into the kitchen to get familiar with the pots and pans. The clerk was a man in his 30s. He went into the kitchen to help with some useless things, whether real or fake.

A few people waited anxiously until 10 o'clock in the evening, and then they saw the lights of the car shining in the yard.

The clerk quickly followed Tang Xiaobo out to greet him, and persuaded Jiang Yuan to come in.

"You must be tired from running. We said we would wait for you to have dinner together..." Tang Xiaobo entered the canteen again and called everyone over loudly.

"Ah... Let's have dinner together. I made hot pot." As he spoke, he saw Mu Zhiyang behind him carrying two large bags, which were Haidilao red.

Wang Chuanxing and Mu Zhiyang took out the pots and bowls, as well as the packed soup bases and dishes, spread them on the table, and returned to the car to get them.

Tang Xiaobo was stunned for a moment, and hurried forward to help, saying: "Why did you buy Haidilao? Where did you buy it from?"

"It was sent from the city." Jiang Yuan was talking about Qinghe City, and said: "Because I saw the plants late, I wanted to make something I could do myself in the evening."

The stoves for takeout hot pots are all equipped, and you can start cooking by plugging in the electricity. Compared with the stir-fried dishes that are taken from far away, they are naturally fresher and more delicious.

Seeing this, Tang Xiaobo simply called his wife over to help him prepare the hot pot.

The two-color soup base was poured into the takeaway simmering hot pot, one red and the other white, reflecting Tang Xiaobo's face, which was also uncertain.

"Captain Jiang, how was your visit today?" Tang Xiaobo asked.

"I only ran around the mountains near the highway in the village, and I couldn't go into the mountains that were too far away." Jiang Yuan paused, and then said: "Compared with the satellite map, there is still a little difference, mainly because many vines and herbaceous plants live under tall trees, and it is not very clear when viewed from high altitude."

"What is the purpose of doing this?" Tang Xiaobo didn't understand.

"To lay a foundation for forensic botany." Jiang Yuan's answer was clear and vague.

Tang Xiaobo looked confused. When he joined the police force, DNA was a thing of the past. Later, after working in the police station, he was basically disconnected from cutting-edge technology.

In fact, let alone him, the criminal police of the provincial department's criminal police team may not be able to come into contact with much forensic botany.

Jiang Yuan did not explain much, and said: "It's just a backup plan. If other technologies can be used to solve the case, I will try to use other solutions. If forensic botany is really needed, I will have an expectation space and a budget space after seeing it in advance."

Forensic botany is not popular, and another reason is that it is expensive.

In particular, the demand for labor costs is very high. Therefore, even in Europe and the United States, forensic botany is rarely used.

People who work 40 hours a week have limited room for forensic botany.

The Litang Township Police Station is located in Ningtai County, and the funds are from Ningtai County, so they naturally cannot be used indiscriminately. Full forensic botany is equivalent to the full trace evidence + mode. Even if all the eucalyptus in Litang Township is solved, it will only hurt the people in the bureau.

However, it is still necessary to lay a foundation for forensic botany. The abnormality of this skill is that it can discover the relationship between people or objects and places, which is a role that other trace detection skills are difficult to achieve.

Tang Xiaobo didn't quite understand, but he understood that Jiang Yuan was ready to do something big.

"Well, okay." Tang Xiaobo didn't want to be Suribachi on Iwo Jima, but at this point, he could only pick up a piece of pork belly and roll it in sesame sauce.

No words all night.

On the third day after arriving in Litang Township, Jiang Yuan sat in the conference room, ready to start a day of cases.

Just like doing cases in other cities and counties, Jiang Yuan sat in the middle of the long conference table, with Wang Chuanxing and Mu Zhiyang helping him. Wu Junhao, who was in charge of the operation, sat next to him and watched, and next to him was Xiao Wang, who was sent by the institute to help.

"The first case." Mu Zhiyang handed Jiang Yuan a book of cases that he had sorted out the day before.

The cases still left in the police station are all small cases, but small cases are also cases, and they also need various evidences, photos, interrogation records, etc. to cooperate.

Jiang Yuan led people to sort out the two days ago, mainly to see the completeness of the evidence, the quality of the photos, and whether the interrogation records were done properly.

If these things are not done well, it will take time to do it again, and a case may not be completed in one day.

On the contrary, if the police in the station have already used up the day's time and completed the preliminary preparations, then Jiang Yuan actually doesn't care what kind of case it is.

Most of the cases, in fact, ordinary police officers have solved them after investigation. The ones that cannot be solved are mainly cases such as theft - although theft cases are only small cases of property infringement, most of them are quite advanced random cases.

There are not many monitoring facilities and checkpoints in the village. To this day, theft cases are still frequent, but the amount involved is not high. Many people do not report the case when they lose their mobile phones, or the case cannot be filed, which makes the total number of cases not large.

The first case Jiang Yuan took on was very special. More than ten steel pipes used to repair the greenhouse were stolen from a farmer's vegetable field, so the farmer called the police.

There was no surveillance in the vegetable field, but footprints and tire tracks were left at the scene.

Jiang Yuan looked at the footprints and then the tire tracks, and felt that it was a bit troublesome to start from the footprints.

The tire tracks were deep and shallow, indicating that the steel pipes were stolen by loading. The thief was probably not a local, so it was a bit troublesome to find someone with the footprints.

It was impossible to investigate for such a small case.

Even if a rough list of names could be drawn through eyewitnesses or visits, it would probably take thirty to fifty day laborers.

Jiang Yuan then focused on the tire tracks.

The tire tracks on the dirt road next to the farmland were very clear.

Jiang Yuan had LV3 vehicle trace identification, but he had been doing more murder cases, so vehicle trace identification basically did not play any role.

Now, looking at the tire tracks of the case, we can get more information.

The police officers at the scene also measured the length and width of the tire tracks, but they had no experience in trace identification, so they were a little unsure about some details.

As for submitting the tracks for identification... it should have been submitted, but the trace inspection in Ningtai County is just Lao Yan and Wang Zhong. If there is any feedback, it will take several days.

Jiang Yuan combined some knowledge of vehicle tracks and directly wrote down the 175/70R14 mark on his hand, handed it to Wang Chuanxing, and said: "Check and see which cars use this model of tires."

"Okay." Wang Chuanxing immediately searched in the intranet.

Jiang Yuan opened the map and studied the route of the highway.

Soon, Wang Chuanxing reported: "Among the original models, there are Nissan Livina, Dongfeng Yueda Kia Maxima... Palio, Wuling Rongguang, Hongguang... Honda Fit..."

"It is most likely Wuling. Other cars cannot fit such a long steel pipe." Jiang Yuan wrote down the names of two county roads on a piece of paper and handed it to Wang Chuanxing, saying: "Show it to the people in the imaging office and ask them to find the car at the right time to see if there are any Wuling Hongguang or Rongguang passing through these checkpoints that night."

Ningtai County's monitoring system was participated in by Jiang Yuan, funded by Changyang City, funded by the provincial department, and acquired by Huang Qiangmin.

Not only is there a complete monitoring system in Ningtai County, but vehicle checkpoints are also installed at important nodes of national highways, provincial highways and county roads.

When driving on highways, national highways, provincial highways, etc., the long strip of camera that flashes when passing by is the vehicle checkpoint. Its working mode is not to take pictures of violations, but to take pictures of the front of the car when passing by.

When the police need to trace back a certain time and a certain car, they can find it through the photos of the vehicle checkpoint.

There are only a few intersecting roads for cars in Litang Township to go out, and there are few cars passing by late at night. If you specify the model, it should be relatively easy to find.

When Jiang Yuan did this, he put the case file in a bamboo basket with a yellow cloth hanging next to it.

The yellow basket means that the case has entered the investigation stage, and the blue one next to it is for the completed case, and the red one is for the difficult case.

Jiang Yuan planned very well and did not encounter bottlenecks in the execution.

In the next Bai Chuang case, after the fingerprint was matched, a file appeared in the blue basket.

Then another one.

Then another one...

By lunch time, there were already 3 files in the yellow basket and 4 in the blue frame.

So much so that when Jiang Yuan came to get food, the chatter in the cafeteria suddenly stopped.

Somehow, a word came to Tang Xiaobo's mind: it can stop children from crying...
