After lunch, Yang Qianfeng went to the office and took the two bags to room 408 of the comprehensive building.

Room 408 is about 12 square meters, the room has a Simmons bed, writing desk and chair, wardrobe, TV, bathroom with electric water heater and other facilities, basically similar to the single room in the hotel.

Yang Qianfeng took out the contents of his bag and sorted them out briefly, and then prepared to go back to his office.

Yang Qianfeng's office is 206; Wang Qingbo's office is 204; Tao Xiaobao's office is 203; 202 and 201 are the office space of the detachment's office, and Qian Zhengfang works in 202; 204 is the office of the commissar of the detachment, and since there is currently no commissar, this office is empty.

Wang Qingbo was waiting for Yang Qianfeng in his office, and Yang Qianfeng stopped when he passed by and said, "Bring a map of the city, let's go,"

Wang Qingbo hurriedly picked up his work bag and stood up and said, "I thought you were going to take a break, but I didn't expect you to come so soon." ”

Yang Qianfeng smiled silently, went to his office to get the work bag, and set off with Wang Qingbo.

The first case occurred on a road outside Shuiyuan Village, Chengnan Town, on the outskirts of the Eastern District, about two kilometers from the city. The second case occurred on the road outside Xiaoxi Village, Chengnan Town, less than three kilometers from the city; The third case was found in an abandoned brickyard at the junction of the urban area and the village of Chakou in Chengnan Township. Every time Yang Qianfeng went to a location, he made a note on the map.

The locations where these three cases were committed (or discovered) all have one thing in common, that is, they are relatively remote, and there are basically no people or cars passing by at night.

According to Wang Qingbo's briefing, the places where the first and second two cases were discovered were the places where the crimes were committed, while the third case was only the place where they were discovered, not the first scene of the case.

After seeing the three places, Yang Qianfeng saw that it was still early, and happened to stop by again, and together with Wang Qingbo, he went to the places where five robbery cases and one robbery and rape case occurred, and marked the places where the cases occurred on the map.

At the morning meeting, Wang Qingbo, Hong Lifei, and others gave a detailed introduction to the two series of cases, and Yang Qianfeng already had a general understanding of the situation of the cases and the investigation situation, and after seeing the places where these cases occurred or were discovered, his understanding of the two series of cases became more three-dimensional.

Yang Qianfeng knew that these two series of cases had indeed seriously affected the people's sense of security and also seriously affected the local image, and he heard that several foreign investors came here a week ago to inspect and found that three taxi drivers had been killed here, and the case had not been solved, so he gave up the idea of investing here and left.

After reading the place where these two series of cases occurred, he and Wang Qingbo came to the Xuanbao East District Public Security Bureau's special case team for a series of cases in which taxi drivers were killed. He wanted to see all the materials in this series of cases, so that he could get a more complete picture of the case and see if he could find anything.

The office of the special case group is located in the Criminal Police Brigade of the Eastern District Public Security Bureau, and the headquarters of the special case group is in the conference room of the brigade. The office building of the Criminal Police Brigade is in a secondary building on the third floor next to the main building of the Eastern District Public Security Bureau, and the conference room is on the east side of the second floor.

After Yang Qianfeng arrived in the conference room, Wang Qingbo immediately took the case materials to him, and he looked at them seriously.

Li Yisheng, captain of the Criminal Police Brigade of the Xuanbao District Public Security Bureau, took people to Chakou Village, Chengnan Town, to carry out an investigation in the afternoon, and when he came back, he heard that Yang Qianfeng's detachment leader was coming, so he immediately ran to the conference room and said to Yang Qianfeng: "Detachment leader, I'll call Director Wang." ”

Yang Qianfeng immediately stopped and said, "Don't alarm your director, let me read these materials first." ”

Wang Qingbo knew that Huang Zhonghui, deputy director of the sub-bureau, had also taken people out to investigate, and asked, "Deputy Director Huang hasn't come back yet?" ”

Li Yisheng said: "According to yesterday's arrangement, the Yellow Bureau took a group of people to the taxi company to investigate, and it is estimated that they will be back soon." ”

In order not to disturb Yang Qianfeng to read the materials, Wang Qingbo and Li Yisheng both withdrew from the conference room.

Yang Qianfeng had a comprehensive understanding of the work of the task force from the materials, focusing on the fact that the task force had reached a consensus through on-site investigation, autopsy, identification of fingerprints and other traces and physical evidence, and investigation and visits. The consensus of the task force is:

1. Collusion and investigation of three cases. The main basis is fingerprints, because multiple fingerprints left by the criminals were extracted from the scene of the first case (in the victim's car), and two mutilated fingerprints were also extracted from the victim's car in the second case (because these two fingerprints were mutilated, although they had a lot in common with the same fingerprints taken from the scene of the first case, they were not convincing enough, so the two cases were not strung together at that time), and three more clear blood fingerprints were extracted from the victim's car in the third case. After comparison by technicians, two fingerprints taken from the scene of the first case and the third case were identical, and after further identification, they were finally identified as fingerprints left by the same finger; Later, the fingerprints taken from the scene of the third case and the second case were compared, and it was found that one of the fingerprints also had many things in common. Based on this situation, the special case group believed that the three cases were committed by the same person and decided to combine the cases for investigation.

2. The criminal committed the crime for one person. In addition to fingerprints, the main basis is also the situation reported by the masses during the survey. Two of the taxi drivers reported that they and the victim driver had met in the urban area before the incident, and although they passed by the car, they clearly saw that the victim had a passenger in the car, but they did not see the appearance of the passenger.

3. The nature of the case is vendetta. Criminals commit crimes with knives, and the main basis for vendetta is that criminals are ruthless when committing crimes, and knives can kill victims; In addition, the criminals did not take the victim's money and any valuable items (such as mobile phones, rings, etc.) after committing the crime, and did not intend to illegally occupy the victim's car. But what made the criminals kill three taxi drivers in such a frenzy is still a mystery.

4. Portraits of criminals. During the on-site investigation, the technicians extracted a bloody shoe print in the victim's car, although it was incomplete, but it was still very valuable for reference, and the task force analyzed that the criminal was a man, aged between 22 and 26 years, and between 1.68 and 1.73 meters tall, with a fat body, but not very fat. In addition, through a comprehensive analysis of the situation at the scene, it is believed that the criminal had a very good psychological quality when he committed the crime, and did not let the driver notice or suspect him before committing the crime each time, resulting in the victim dying without knowing anything when the disaster came.

V. Scope of Investigation. The urban area of Xuanbao East District, Chengnan Town and some areas adjacent to the West District are key investigation areas.

After the five major consensus was formed, the task force worked to find the suspects within the scope of the investigation, focusing on: people who had conflicts with the three victims in the taxi industry; A person who has had a conflict with a customer in the past when the victim was doing business; Those who are subject to legal treatment and who are released from prison or who return from re-education through labor and hate society or the taxi industry. Through the work of all the comrades of the special case group day and night for nearly a month, no criminal suspect was found.

After reading the main materials, Yang Qianfeng felt that the work of the task force was serious and careful, and that the vast majority of all the consensus reached had a scientific basis, and the few that had no scientific basis were reasonable.

Yang Qianfeng closed the materials and thought about it seriously, believing that the characterization of this case was correct and must be related to Qiu, but he believed that there were also deficiencies in the consensus reached by the task force. For example, the task force believes that the criminal has a bad record, but he feels that it is too arbitrary, and with his intuition, the criminal may not have committed a crime before and has been dealt with. In addition, the scope of searching for key people is too small, and this will constrain the minds of investigators and will not help them give full play to their subjective initiative......

When he was thinking about how to go deeper in the next step, Wang Zheng suddenly appeared in front of him, and Yang Qianfeng stood up happily and said, "Old Director, I told Captain Li not to alarm you, why did I still alarm you?" ”

Wang Chongyi grabbed Yang Qianfeng's hand and said, "You also said that I scolded him just now, and for the sake of the case, I didn't let him notify me when I came." ”

Yang Qianfeng let go of his hand and said, "Aren't you afraid that you'll be busy!" Have a seat. He sat down.

Wang Chong sat down and said, "How do you feel about the material?" ”

Yang Qianfeng patted the material and was about to speak, Hong Lifei came, and said to Wang Qingbo as he entered the door: "Call all the comrades of the task force to the conference room for a meeting." ”
