Tang Xiaobo waited until noon, but did not wait for Jiang Yuan, and continued to wait patiently until the evening. Then at eight o'clock in the evening, the cafeteria lady quit.
The cafeteria lady was about the same age as Tang Xiaobo. She tugged on her apron and said, "My wife is still waiting for me to go back and watch TV series. If you want to cook, you can cook it yourself tonight. Leave the bowl for me and I'll come tomorrow morning."
wash."
Tang Xiaobo stood up helplessly and said, "I'm sorry, due to special circumstances today, I have delayed your departure from get off work."
"There's no need to delay. It's hard for you to be an official, but I can't wait any longer." The aunt waved her hand and rode back on her electric bicycle without being polite at all.
Tang Xiaobo had no choice but to call his wife Wang Xiuyun and ask her to come to the rescue.
Not long after, Wang Xiuyun arrived. As usual, she scolded Tang Xiaobo first, and then said: "You asked me to come over to cook, why not invite them to your home for dinner. Didn't you always invite your colleagues home for dinner before? You were so cordial.
point."
Surrounded by close confidants, Tang Xiaobo just sighed and said, "It's hard to show such closeness."
"Then you still ask 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 are doing is more difficult than raising pigs. You are afraid that the pigs will eat too much and have diarrhea, and you are also afraid that the pigs will lose fat if they eat too little..."
When Tang Xiaobo thought about Chai Tong and then Huang Qiangmin, he almost burst into tears when his wife told him.
Wang Xiuyun went into the kitchen to familiarize herself with the pots and pans. The back-office clerk was a man in his 30s. He came into the kitchen and offered some useless help.
Several people waited eagerly until 10 o'clock in the evening when they saw car lights shining in the yard.
The internal staff quickly followed Tang Xiaobo out to greet him, and persuaded Jiang Yuan to be brought in.
"You are tired from running. We also said that we would wait for you to have dinner together..." Tang Xiaobo came back to the cafeteria door and called everyone over loudly.
"Ah... let's eat together. I made hot pot." As he spoke, he saw Mu Zhiyang behind him carrying two large bags, the appearance of which was the red color of Haidilao.
Wang Chuanxing and Mu Zhiyang took out the pots and pans inside, as well as the packaged pot bottoms and vegetables, spread them out on the table, and then returned to the car to get them.
Tang Xiaobo was stunned, and quickly stepped 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 added: "Because I didn't look at the plants until late, I just wanted to do something I could do at night."
The stoves in takeout hotpots are all equipped and you can start cooking them just by plugging in the electricity. Naturally, they are fresher and more delicious than the stir-fried dishes that are taken out from afar.
When Tang Xiaobo saw this, he simply called his wife over and arranged the hot pot together.
The two-color soup base is poured into the take-out mandarin duck pot, one side is red and the other is white, reflecting Tang Xiaobo's face, which is also uncertain.
"Captain Jiang, how was your viewing today?" Tang Xiaobo asked.
"I just ran to the mountainous areas near the road in the countryside. I can't go to the mountains that are too far away." Jiang Yuan paused and then said: "Comparing the satellite images, there is still a little difference, mainly because there are many vines.
Plants, herbaceous plants, live under tall trees, and you can’t see them very clearly from a high altitude.”
"What's the purpose of doing this?" Tang Xiaobo didn't understand.
"To lay a foundation for forensic botany." Jiang Yuan answered clearly and vaguely.
Tang Xiaobo looked confused. When he joined the police force, there was no trace of DNA. Later, after he started working at the police station, he was basically disconnected from cutting-edge technology.
In fact, let alone him, the criminal policemen of the provincial criminal police team may not have access to much forensic botany.
Jiang Yuan didn't explain much, and just said: "Actually, it's just a guarantee. If other techniques can be used to break the eucalyptus, I will try to use other solutions. I really have to use forensic botany. I have seen it in advance, so that's it.
There will be an expectation space and a budget space.”
Another reason why forensic botany is not popular is that it is expensive.
In particular, the demand for labor costs is very high. Therefore, even in European and American countries, forensic botany is rarely used.
People who work 40 hours a week have limited room to develop in forensic botany.
Litang Township Police Station is on the territory of Ningtai County, and the funds are from Ningtai County. Naturally, it cannot be used indiscriminately. The whole process of forensic botany is equivalent to the whole process of trace evidence + mode. Even if the Litang Township police station is used,
If the eucalyptus is completely broken, it will only cause pain to the people inside.
However, it is still necessary to have a foundation in 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 inspection skills are difficult to achieve.
Tang Xiaobo didn't quite understand, but he understood that Jiang Yuan was preparing for a big fight.
"Hey, okay." Tang Xiaobo didn't want to be like Mount Suribachi on Iwo Jima, but at this point, he could only pick up a slice of pork belly and roll it in the sesame sauce.
A night of silence.
On the third day after arriving in Litang Township, Jiang Yuancai sat in the conference room, preparing to start the day's work properly.
Just like working 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 and watched, and next to him was Xiao Wang, who was sent by the institute to help.
"The first one." Mu Zhiyang handed a copy of the documents he had sorted out the day before to Jiang Yuan.
The eucalyptus still left at the police station are all small eucalyptus, but the eucalyptus is also a eucalyptus, and they also need various evidences, photos, interrogation records, etc. to support them.
Jiang Yuan led people to sort it out in the past two days, mainly to look at the completeness of the evidence, the quality of the photos taken, and to ask whether the transcripts were properly prepared.
If these things are not done well, you will have to spend time to do them all over again, and you may not be able to complete one piece in a day.
On the contrary, if the police in the station had already spent this day and completed the preparatory work, then Jiang Yuan would not really care.
In fact, most of the bugs are broken by ordinary police investigations. The ones that cannot be broken are mainly the bugs such as theft - don't think that the bugs are just small bugs that invade property, the biggest ones among them are
Part of it is quite advanced random manipulation.
There are few surveillance facilities and few checkpoints in the countryside. To this day, theft-related cases are still high, but the amount involved is never high. Many people do not report lost mobile phones, or they cannot be filed, making the total number of cases
It's just a small quantity.
The first call Jiang Yuan picked up was very unique. More than ten steel pipes used to repair the greenhouse were stolen from a farmer's vegetable field, so he called the police.
Naturally, there was no surveillance in the vegetable field, but footprints and ruts were left on the site.
Jiang Yuan looked at the footprints and then at the ruts, feeling that starting from the footprints would be a little troublesome.
The ruts are deep and shallow, indicating that the steel pipe was stolen on a truck. The thief is probably not a local, so it would be a little troublesome to find someone with the footprints.
It's impossible to conduct an investigation for such a small eucalyptus.
Even if a rough list could be drawn up through eyewitnesses, interviews, etc., it would probably cost thirty or fifty daily labor.
Jiang Yuan then focused on the rut.
The tracks on the dirt road next to the farmland are very clear.
Jiang Yuan has LV3 vehicle trace identification, but there has always been a lot of accidents, and the vehicle trace identification has basically played no role.
At this time, more information can be obtained by looking at the existing ruts.
The police at the scene also measured the length and width of the ruts, but they had no experience in identifying traces and were somewhat unsure about some details.
As for submitting for trace inspection and identification... it should have been submitted, but the trace inspection in Ningtai County was carried out by Lao Yan and Wang Zhong. If there is any feedback, it will take several days.
Jiang Yuan combined some knowledge of vehicle traces and directly wrote down the label of 175/70R14 on hand, handed it to Wang Chuanxing, and said: "Check and see what cars use this type of tire."
"Okay." Wang Chuanxing immediately started searching on the intranet.
Jiang Yuan opened the map and studied the highway route.
Soon, Wang Chuanxing reported: "Among the original models, there are Nissan Liwei, Dongfeng Yueda, Kia Maxima... Palio, Wuling Rongguang, Hongguang... Honda Fit..."
"It's most likely Wuling. Other cars can't fit into such a long steel pipe." Jiang Yuan wrote the names of two more county roads on the paper, handed it to Wang Chuanxing, and said: "Show it to the people in the imaging office and let them
Take the time to look for a car and see if there is a Wuling Hongguang or Rongguang passing by these checkpoints that night."
The monitoring system in Ningtai County was controlled by Jiang Yuan, Changyang City paid for it, the provincial government allocated funds, and Huang Qiangmin took over.
Not only does Ningtai County have comprehensive surveillance, but vehicle bayonet points are also installed at important nodes on national, provincial and county roads.
When driving on highways, national highways, provincial highways, etc., the long strip camera that flashes when passing by is the vehicle bayonet. Its working mode is not to take pictures of traffic violations, but to take pictures of the front of the car when passing the car.
When the police need to trace a certain vehicle at a certain time, they can look for it through photos of the vehicle's bayonet.
When driving out of Litang Township, there are only a few intersecting roads, and there are very few cars passing by late at night. If you specify the car type, it should be relatively easy to find.
When Jiang Yuan reached this point, he put the eucalyptus file into a bamboo basket with a yellow cloth hanging next to it.
The yellow basket means that the case has entered the investigation stage, the blue one next to it is for the completed cases, and the red one is for the difficult cases.
Jiang Yuan planned well and encountered no bottlenecks in execution.
In the next game, after matching the fingerprint, a dossier appeared in the blue basket.
Then another one.
Then another one...
By lunch time, there were three dossiers in the yellow basket and four in the blue frame.
So when Jiang Yuan came to get food, the chatter in the cafeteria suddenly stopped.
Somehow, a word came out of Tang Xiaobo's mind: Stop the baby from crying...
