After dinner, Yang Qianfeng has been sitting in the office while smoking a cigarette while carefully studying the law and characteristics of various cases in the jurisdiction, he drew a topographic map of the jurisdiction, drew a circle on the place where the enterprise was stolen, drew a triangle on the place where the shops of the grassroots supply and marketing cooperatives and individual shops were secondary, drew a small square on the village where the poultry was stolen and the place where the fish was stolen frequently, and drew a small rectangle on the approximate location of the bare aluminum wire stolen, so that the whole case situation could be displayed in front of him at a glance.

Yang Qianfeng looked at the picture and carefully analyzed the case situation introduced by the three comrades in the institute, and wanted to find out the law and characteristics of each type of case, he believed that the case of enterprise theft should be committed by locals, and it was not done by a group of people, it seems that the infringement is all about the enterprise, and the stolen things are aimed at the equipment, as if it was done by a group of people, but he thinks that it is not necessarily, it is very likely that it is two groups of people, and preliminarily concludes: three cases of Lin Mao Special Pump Factory (one is the mechanical equipment being installed, two are metal parts) was done by a group of people; The two cases of Fengshan Magnetic Material Factory (the stolen machinery and equipment being installed) and the Tieshan Township Concentrator Plant (the stolen machinery and equipment in use) should have been committed by another person.

Lin Mao special pump factory is the largest township enterprise in Lin Mao Town, the production of products are sold all over the country, the benefits are very good, every year to the town of more than 1.8 million, is one of the main economic sources of the town finance, the staff in the factory are Lin Mao Town people, no outsiders, the factory is surrounded by a high wall, the guards are 24 hours a day, someone wants to go in is not so easy, so every time the criminals steal is not far from the things they want to steal in the perimeter wall to punch holes in and out, The three thefts were all in the second half of the night when the factory did not go to work, and through the on-site investigation by Li Chunsheng and the criminal police team, it was determined that two people should have committed the crime, and Yang Qianfeng believed that these two people were from Lin Mao Town, and they were familiar with the situation in the factory.

Fengshan Magnetic Materials Factory is the largest enterprise in Fengshan Township, although the products produced are not as hot as the products of Lin Mao Special Pump Factory, but the benefits are also good, it is an important pillar of the township's finances, last year to put on new products, so the plant was expanded, and the installation of new machinery and equipment began at the beginning of this year, and before the Spring Festival and after the Spring Festival, these equipment were stolen twice, resulting in the company's new products have not been launched until now, although Yang Qianfeng did not go to this enterprise, but you also know some information through Li Chunsheng's introduction, The new plant is on the edge of the old plant, the workshops of this factory are not installed with gates, and the new plant is not, I wanted to take the next step to build a fence between the new plant and the old plant, and enter and exit from the gate of the old factory, so this new plant is equal to open, although the security work is handed over to the factory guard, but it is also like a fictitious, and the guard on duty on a cold day only goes to the outside of the plant before going to bed to go around, and does not go into the house to inspect at all, so the criminals steal machinery and equipment from the new plant as if they are in a no-man's land, No other means of committing the crime are required; The concentrator is a supporting enterprise of the Tieshan Copper Mine, the concentrator is far away from the village and the copper mine headquarters, and there is no one on duty there at night, even if all the machinery and equipment there are removed and transported away at night, no one may be able to find out. Yang Qianfeng calculated according to the number of items stolen in these two places, and also believed that at least two or more people committed the crime, because some things could not be moved by one person, and thought that he brought a means of transportation. And this group of people, Yang Qianfeng, thinks that it is very likely to be from Fengshan Township.

The cases of theft of shops, consignment stores and unit offices are mainly concentrated in Fengshan Township, Yang Qianfeng looked at the different graphics of his subject and found that there are really a lot of theft cases in Fengshan Township, the government office of Fengshan Township has been stolen twice, and one street shop has been stolen three times, one has been stolen twice, and one has been stolen once, and the three big ones have been stolen a total of six times, and the consignment stores in each village have basically been patronized by thieves as Li Chunsheng said when he introduced them. Through careful analysis and research, Yang Qianfeng found that these theft cases have common characteristics: first, the perpetrators are two people; 2. The time of the crime occurred at night; 3. Just money, cigarettes and alcohol, and nothing else; Fourth, there is no camouflage, and a lot of fingerprints and footprints are left at the scene; Fifth, the crime tool is single, and through many traces left at the scene, it is found that the perpetrator brought a bolt cutter and a large screwdriver.

Thinking of the common denominator of these cases, Yang Qianfeng lit a cigarette, and arranged the specific dates of these cases, and found that most of these cases happened on Saturday night, and he suddenly thought of whether it was a student who committed the crime, and then looked at the cases that did not occur on Saturday, and found that the cases that did not occur on Saturday were all during the student vacation, and he smiled happily, because he concluded that it was done by two students, and these two students were very likely to be dormitory students who went to school in the county, and they had the opportunity to commit crimes when they came back on Saturday. I didn't stop during the holidays, but the relative number of times was much less, no wonder the criminal police team couldn't touch them many times, it turned out that they went to school after committing the crime, and they had cigarettes and alcohol every time they stole it, which made people think that adults did it.

Although the cases of poultry theft are everywhere, he found that they are mainly concentrated in Lin Mao, Fengshan and Ziyang Village, which are adjacent to Lin Mao and Fengshan in Piling Township, and the traffic in the place where the crime occurred is relatively convenient.

It can be said that the criminals are shooting a shot to change a place, and there is no rule in the interval between crimes, sometimes two cases occur in a month, sometimes there is no one for three consecutive months, but the number of thefts is seen as at least two or more perpetrators, and the possibility of three people is extremely high. Whether it was a local or a foreigner who committed the crime, Yang Qianfeng did not dare to determine for a while. Yang Qianfeng wants to make it easy first and then difficult, and this case can only be taken slowly.

After comprehensive research and analysis, Yang Qianfeng believes that there are many tasks that can be done at present, from easy to difficult, and he wrote in his work notes:

1. The work to be done in cases of theft of shops, consignment stores and unit offices. 1. Comprehensively explore the students who live and study outside in Fengshan Township and come back every week; 2. Go to the schools of these students to understand the performance of these students and their related persons; 3. Understand the financial situation of these students' families and the use of money in school; 4. Identify key people from these people and collect their fingerprints, and try to collect their shoe prints.

Second, the work to be done in the theft case of Linmao Special Pump Factory. 1. Carry out the work of mapping and arrangement. Investigate the people with bad criminal records in the jurisdiction, focusing on the people of Lin Mao Town who have such a history of theft locally or in other places, and those who like to gamble (including playing mahjong all day long) without proper income, and find out the real reason for his self-harm when Zhang Wenjie and Xu Xiaohu interrogated him last time, and at the same time find out who his cellmates are and his current living situation; 2. Investigate the waste acquisition points in the local and surrounding areas and the city, investigate and register the local scattered waste acquisition personnel, and understand the whereabouts of the items they receive; 3. Establish a project or special service; 4. If necessary, visit the county's scrap purchase and scrap metal collection enterprises.

3. The work to be done in the case of the theft of the Fengshan Magnetic Material Factory and the Tieshan Township Concentrator Plant. Basically, the work to be done is the same as the theft case of Lin Mao Special Pump Factory, and some of the work is combined.

Fourth, the work to be done in cases of theft of poultry and cases of stealing and cutting of bare aluminum wire in use. 1. Go to the detention center to learn about the list and basic information of these criminal convicts in the county in the past ten years, focusing on those who have been released from prison, and ask all police stations to help investigate their current situation; 2. Visit the people who do poultry business such as Sunshine Town Vegetable Market and Linmao Vegetable Market, and screen key people from them; 3. Establish a project or special service.

Note: When conducting an investigation of the local and surrounding waste collection points and in the city, it is necessary to conduct a comprehensive investigation of the local stolen items, including the stolen items and bare aluminum wire from the three factories.

Some of the people drawn by several units have already arrived, they are in the conference room on the second floor, four people play poker and others sit on the side to watch, Li Chunsheng and Zhang Wenjie also arrived early, Li Chunsheng is writing materials in the office, Zhang Wenjie is accompanying the people who have been drawn, Lin Xiaoxiong went to bed after dinner, he said that he fell asleep and got up to do the work in spirit.

After Yang Qianfeng finished writing, he looked at his watch at more than nine o'clock, and set up to officially start work at ten o'clock in the evening, and now there is still nearly an hour before he goes to work, Yang Qianfeng leaned on the chair and wanted to close his eyes and rest for a while, but he didn't close his eyes for a while and found that someone came in, and when he opened his eyes, he found that it was Lin Xiaoxiong and said: Brother is resting?

Lin Xiaoxiong said embarrassedly: I'm sorry to wake you up.

Yang Qianfeng sat up straight and said, "It's okay, sit down." As he spoke, he pushed the topographic map and notebook he drew in front of Lin Xiaoxiong and said: We still have a lot of work to do in the next step, you can see what work has not been considered.

Lin Xiaoxiong took it and pinched the earrings and said: I'll take a look first.

Yang Qianfeng got up and said: "Look first, I went upstairs to see the people from the brother unit."

Lin Xiaoxiong's eyes lit up when he saw the topographic map, originally he felt that Yang Qianfeng was more thick than fine, he really didn't expect that he was completely more detailed than thick, the map in front of him made him see the public security situation in the jurisdiction at a glance, and what surprised him even more was that Yang Qianfeng sat in the office and delineated the scope of the perpetrators of the Fengshan series of theft cases, and was reasonable, and at the same time made such detailed arrangements for the next step, after reading it, he was excited, as if he had straightened out the knot in his heart for a long time. I think that people are different from people, these things may never be as smooth as Yang Qianfeng's reasoning, in the past, these things in the face of the jurisdiction were always messy, and I don't know where to fork it, but now after Yang Qianfeng's reasoning, it seems that everything is very simple, and he really admires the five-body throw.

Yang Qianfeng returned to the office Lin Xiaoxiong instinctively stood up and said: Director Yang, you will definitely not stay in this small temple of Lin Mao for a long time, and you will definitely be the leader of our bureau in three or five years.

Yang Qianfeng looked at him puzzled and said: I just came and wanted to drive me away! How do you get to this point? Sit down, you don't have a fever!

Lin Xiaoxiong pointed to the topographic map and notebook and said: You have only been here for a few days, the things here are clearer than us, the people of the criminal police team have been here many times, and they have not come up with a decent investigation measure and countermeasure, and the Fengshan series of cases have not even touched the edge, and you can see at once that those cases were done by students, it is really a god, and these arrangements are ......

Yang Qianfeng hurriedly stopped him and said: I can't say that, I can think of these things on the basis of their work. He took a sip of tea and continued: We carry out prevention and control in order to prevent or reduce the number of cases, and strive to catch some current crimes, and it is still up to us to solve the backlog of cases, and it is impossible for the criminal police team to live here and help us solve cases every day, so I have studied and analyzed it carefully, and the masses look at the key to public security to solve the case, and if the case cannot be solved, no matter how good the management is, it is not perfect, and the masses still have opinions, and you are right.

Lin Xiaoxiong said: Yes, yes, yes.

Yang Qianfeng asked: Do you have anything to add?

Lin Xiaoxiong pinched the earrings and said: No, no, you think very well.

Yang Qianfeng looked at his watch and said: It's almost time, let's go up and say a few words and set off.

Lin Xiaoxiong stood up happily and said: "Okay! Everyone's enthusiasm is high.
