Chapter 576 Red Yellow Blue

Tang Xiaobo waited until noon, but did not wait for Jiang Yuan, and continued to wait patiently until the evening, and then at eight o'clock in the evening, the lady in the cafeteria quit.

The lady in the cafeteria was about the same age as Tang Xiaobo, pulled her apron, and said, "My wife is still waiting for me to go back to watch TV dramas. If you want to cook, you can do it yourself at night. I will save the bowl and I will come tomorrow morning." wash."

Tang Xiaobo got up helplessly, and said, "I'm sorry, today's special situation has delayed your get off work."

"There is no delay, no delay, you have worked hard as officials, but I can't wait." The aunt waved her hand, and rode back on her battery car, not polite at all.

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

Not long after, Wang Xiuyun arrived, scolded Tang Xiaobo first as usual, and then said: "You called me over to cook, it's better to invite someone to eat at home. Didn't you always invite colleagues home for dinner before? You still look kind point."

Surrounded by cronies, Tang Xiaobo just sighed and said, "It's not easy to appear so close."

"Then you still call me to cook?"

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

Wang Xiuyun looked at her husband, shook her head and said, "What you do is worse than raising pigs. You are also afraid that the pigs will have diarrhea if you eat too much, and you will lose fat if you eat too little..."

Tang Xiaobo thinks about Chai Tong, and then thinks about Huang Qiangmin, tears will fall when he is told by his wife.

Wang Xiuyun went into the kitchen to familiarize herself with the pots and pans.The back office is a man in his 30s, and it is useless to help in the kitchen.

Several people waited eagerly until 10 o'clock in the evening, only to see car lights shining in the yard.

Neiqin hurriedly followed Tang Xiaobo out to greet him, and brought Jiang Yuan in with some kind of rhetoric.

"You're tired from running, we said we'll have dinner with you..." Tang Xiaobo entered the cafeteria again and called everyone over loudly.

"Ah... It's good to have dinner together, I made a hot pot." While talking, I saw Mu Zhiyang behind him carrying two big bags, the appearance of which was Haidilao's red.

Wang Chuanxing and Mu Zhiyang took out the pots, bowls and chopsticks, as well as the packaged pot bottoms and vegetables, spread them on the table, and returned to the car to pick them up.

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

"It was sent from the city." Jiang Yuan said Qinghe City, and said again: "Because I was late to see the plants, I wanted to get something I could make at night."

The stoves for the takeaway hot pot are all equipped, and you can cook them when you plug in the electricity. Compared with the stir-fried dishes delivered all the way, they are naturally fresher and more delicious.

Seeing this, Tang Xiaobo simply called his wife over and set up a hot pot together.

The two-color soup base was poured into the takeaway mandarin duck pot, one side was red and the other was white, reflecting Tang Xiaobo's face, it was also cloudy and sunny.

"Team Jiang, how did you watch today?" Tang Xiaobo asked.

"It's just running around the mountains near the road in the village, and you can't go to the mountains that are too far away." Jiang Yuan paused, and then said: "Compared with the satellite image, there is still a little difference, mainly because there are many vines Plants, herbaceous plants, live under tall trees, and it is not very clear to see them from a high altitude."

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

"Give me a foundation in forensic botany." Jiang Yuan answered clearly and vaguely.

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

In fact, let alone him, the criminal police of the provincial and departmental criminal police team may not have much contact with forensic botany.

Jiang Yuan didn't explain much, and said: "Actually, it's just a guarantee. If I can use other techniques to solve the case, I'll try to use other solutions. I really need to study forensic botany. If you read it in advance, you can do it." There's room for expectations, there's room for budget."

Another reason why forensic botany is not popular is that it is expensive.

Especially the demand for manpower cost is very high.Therefore, even in European and American countries, forensic botany is rarely used.

Someone who works 40 hours a week has limited room to play in forensic botany.

Litang Township Police Station is located on the territory of Ningtai County, and the funds are allocated from Ningtai County's funds, so naturally they cannot be used indiscriminately.The whole process of forensic botany is tantamount to the whole process of trace physical evidence + mode. Even if all the cases in Litang Township are solved, it will only cause pain to the insiders.

However, a foundation in forensic botany is still necessary. The abnormality of this skill lies in the ability to discover the relationship between people or objects and places, which is difficult for other trace detection skills to achieve.

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

"Hey, that's fine." Tang Xiaobo didn't want to be like Mount Suribachi on Iwo Jima, but at this point, he could only pick up a piece of pork belly and roll it hard in the sesame sauce.

Silent all night.

On the third day after arriving in Litang Township, Jiang Yuan sat in the conference room, ready to start the day's case.

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

"The first real case." Mu Zhiyang handed Jiang Yuan a copy of the case that he sorted out the day before yesterday.

The cases that remain at the police station are all small cases, but small cases are also cases, and various evidences, photos, interview records, etc. are needed to cooperate.

Jiang Yuan led people to sort it out two days ago, mainly to look at the completeness of the evidence, to see whether the photos were taken well or not, and to ask whether the transcripts 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 policemen in the office have already spent the whole day and completed the preparatory work, then Jiang Yuan doesn't really care what the case is.

Most of the cases, in fact, were solved by ordinary police investigations.The ones that can't be solved are mainly theft and other cases-although theft is just a small case of property infringement, most of them are quite advanced random crimes.

There are no monitoring facilities in the village, and there are few checkpoints. Today, theft cases are still high, but the amount involved is not high. Many people lose their mobile phones and do not report, or cannot be registered, making the total number of cases small.

The first case Jiang Yuan took up was very distinctive. In a farmer's vegetable field, more than a dozen steel pipes used to repair the greenhouse were stolen, so he called the police.

Naturally, there was no surveillance in the vegetable field, but footprints and ruts were left on the scene.

Jiang Yuan looked at the footprints, then at the ruts, and felt that starting from the footprints was a bit troublesome.

The ruts are deep and shallow, indicating that the steel pipes were stolen by trucks.The thief is probably not a local. In this way, it is a little troublesome to find someone with footprints.

It is impossible to investigate such a small case.

Even if a rough list can be drawn through eyewitnesses, interviews, etc., it will probably cost thirty to fifty daily workers.

Jiang Yuan then focused on the rut.

On the dirt road next to the farmland, the ruts are very clear.

Jiang Yuan has LV3 vehicle trace identification, but there have been a lot of homicide cases, and vehicle trace identification has basically not played any role.

Looking at the ruts of the current case now, we can get more information.

The policemen at the scene also measured the length and width of the ruts, but they had no experience in identifying traces, so they were somewhat uncertain about some details.

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

Combined with a little knowledge of vehicle traces, Jiang Yuan directly wrote down the 175/70R14 mark on his hand, and handed it to Wang Chuanxing, saying: "Check and see, what kind of cars use this type of tires."

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

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

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

"It's probably Wuling. Other cars can't fit in such a long steel pipe." Jiang Yuan wrote down the names of two county roads on the paper, handed it to Wang Chuanxing, and said, "Show it to the people in the imaging office and let them see it." Take the time to find a car and see if there are Wuling Hongguang or Rongguang passing these checkpoints that night."

The monitoring system in Ningtai County was participated by Jiang Yuan, paid by Changyang City, funded by the provincial department, and bitten down by Huang Qiangmin.

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

When driving on expressways, national and provincial highways, etc., the long strip of cameras that flash when passing by is the vehicle bayonet.Its working mode is not to take pictures of violations, but to take photos of the front of the car when passing the car.

When the police need to go back to a certain car at a certain moment, they can look for it through the photos of the vehicle bayonet.

There are only a few intersecting roads for cars in Litang Township, and there are very few cars passing by in the middle of the night. If you specify a car model, it should be relatively easy to find.

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

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

Jiang Yuan's plan was very good, and the execution did not encounter bottlenecks.

In the next white case, after matching the fingerprints, a dossier appeared in the blue basket.

And then another one.

And then another...

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

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

In Tang Xiaobo's mind, for some reason, a word popped up: Can stop children from crying...
