teach me how not to be the police

() At twelve o'clock in the evening, all the project workers who had been busy all day gathered in the large conference room on the second floor of the Chenggong Police Station. There were too many people, and the corners of the conference room were full of people. Director Xiong kept arranging people. I went to other offices to give chairs to the standing people; Xiao Hu was also busy distributing cigarettes for everyone, and another team member was also busy pouring water for everyone.Everyone smoked, drank water, and discussed in low voices. The meeting room was full of smoke, and the smoke was floating around.

"Everyone be quiet, the meeting will start on the spot." Director Tang spoke, and the meeting room immediately fell silent.

"The following groups report on the situation. If you have something to say, make it long, and if you have nothing to say, make it short, don't worry about mother-in-law. Which group will talk first?"

Director Zhang said, "The on-site inspection will be the first to talk."

Team Ke: "On behalf of the technicians, I will first introduce the situation on site, and Lao Zheng will make supplements."

"The scene is located in Liu Haiyang's non-staple food store opposite the old supply and marketing cooperative in the center of Chenggong Town. The store is north of Provincial Highway 214, and on the east side of Line 214 is a row of bungalows. There are 20 rooms, each of which is divided into two small rooms. The small room is used for non-staple food business, and the other small room is used as accommodation. Behind the bungalow is a pond. Liu Haiyang’s non-staple food shop bungalow is located in the middle of the 20 bungalows. There is a wooden door on the north side, and the door is bolted from the inside. , it was Liu Haiyang's father, Lao Liu, who used a crowbar to pry open the wooden door. There were fresh prying marks on it, and there were no other signs of vandalism on the door. At the same time, we also investigated, and there were many witnesses who saw Lao Liu prying the door. the process of."

"In the non-staple food store, there are shelves at the bottom of the east and west walls. On the shelves are non-staple food groceries such as cigarettes, alcohol, snacks, and daily necessities. After a preliminary inventory, no obvious traces of flipping were found, and the items were placed in a relatively neat and orderly manner. A window was opened on the south wall, and the window was separated by steel bars. There were no obvious signs of prying damage. The glass window was closed, and there were dark curtains inside. There was a dead body lying on the ground between the shelves on the east and west sides. After identification , the deceased was Liu Haiyang. Liu Haiyang was facing the sky, his head was south and his feet were north. He was wearing long johns, his eyes were wide open, and his hands were clenched into fists. They were located on both sides of his body, and the back of his body was covered with blood, forming a pool of blood. The area of ​​the pool was 8 *6cm, there was a 10cm long open wound on the left neck, 3cm deep, there were 11 wounds on the back and left forearm, all of different lengths, ranging from 5-10cm, all of which reached the bone. Forensic autopsy It shows that Liu Haiyang died of hemorrhagic shock after open trauma."

"There is a wall between the non-staple food room and the dormitory room. There is a wooden door at the north end of the north wall of the wall. The wooden door is open. There is a window under the north wall. Under the window is a gas stove and other stoves. There is also a window on the south wall. , the north and south windows are separated by steel bars, no obvious signs of prying damage are seen, the glass windows of the two windows are closed, and there are dark curtains inside. There is a bed in the southeast corner of the accommodation room, and the bed is prone A female corpse, in a kneeling position, with the upper body lying on the bed, with blood stains on the upper and lower parts of the corpse, covering an area of ​​7*6cm. The head of the corpse is facing east, and the feet are kneeling beside the bed. There is also a 10cm-long open xing wound on the left side of the neck. , deep to the throat, wearing long johns, and forensic examination showed no traces of sexual invasion. After identification, the corpse was Liu Haiyang’s wife Ke Guifen, and the cause of death was hemorrhagic shock after trauma, which was basically the same as Liu Haiyang’s. Autopsy of the corpse , it can be seen that there is a fetus in Ke Guifen's womb, which is three months old, and the rest are normal. This is one dead body and two lives."

Director Zhang: "According to what you said, there are no signs of damage to the doors and windows, so how did the perpetrators get in? How did they get out?"

"There are indeed no signs of damage to the doors and windows, and the wooden door of the non-staple food room is also bolted from the inside, so it is impossible for outsiders to enter. However, everyone still needs to think three-dimensionally, that is, the sky and the ground, and the ground is the concrete floor. possible, so we turn our attention to heaven.

Liu Haiyang's non-staple food store is a one-story house, and it is 2.8 meters high in the north and 2.3 meters low in the south, which means it is higher near the road and lower near the pond.The roof is covered with asbestos tiles. We found a 25*23cm hole in the asbestos tiles in the non-staple food room. There are fresh fracture marks around the hole. From these signs, we can be sure that this is where the perpetrators entered and exited. The place, that is to say, is also here when you enter, and this is also where you leave.

After our careful investigation, here we found two incomplete shoe sole patterns, one with blocks and the other with circles, both of which only reflect partial patterns and are not complete, but it is certain that they are left by the suspect.Because these two kinds of footprints are left near the entrance of the scene, they are very fresh, and we also visited, and no one has been here after the case.

In addition, there are fibrous tissue residues at the break. The analysis may be the fibers on the glove or the clothes hanging on the break. It is currently unclear whether it is the glove print or the fibers of the clothes. It can only be determined after the identification. "

"According to the above inspection results, we conducted an on-site analysis and the opinions are as follows:

First of all, the nature of the case is homicide.This is an organized and premeditated homicide case. As for the cause of the murder, further analysis is needed. The property infringement is not very obvious, and there is no trace of tampering with the items in the house; there is no evidence for the murder of love.

Secondly, the number of perpetrators was not less than two people. Judging from the patterns on the soles, young and middle-aged people may be more sexual. The specific analysis still needs further work, and we will do it as soon as we go back.

Third, the tools used to commit crimes are sharp tools. From the perspective of the length of the wound, it may be a tool such as a kitchen knife or an axe. From the perspective of depth, the possibility of an ax is greater.

Fourth, the process of committing the crime is as follows: the perpetrator touched the edge between the pond behind the non-staple food store and the non-staple food store to the window on the south side of Liu Haiyang's non-staple food store. 25*23cm hole, and then enter the store through the hole.At this time, Liu Haiyang probably heard the movement, so he got up and came to check, and encountered the perpetrator in the non-staple food room.Perpetrator A obviously didn't expect Liu Haiyang to get up, and hurriedly hacked Liu Haiyang with an axe. Seeing someone hacking himself, Liu Haiyang desperately resisted. Therefore, Liu Haiyang not only suffered fatal neck injuries, but also resisted wounds on his body; while the other perpetrator Person B rushed to the dormitory room quickly, and held Ke Guifen who was about to get out of bed after hearing the noise. After perpetrator A killed Liu Haiyang, he quickly rushed to the dormitory room inside, and together with perpetrator B, Kill Ke Guifen who was getting ready on the bed, and then escape from the same way. "

"In terms of traces and physical evidence: there are tool traces, which are in the shape of an axe; there are two types of footprints. Although the footprints are incomplete, they meet the identification conditions. Please keep this aspect secret, and keep it secret to the outside world. This is a sharp weapon we will use in the future; fingerprints. There are few fingerprints, but further screening is needed, and no blood fingerprints have been found. Let me add here, considering the possibility of the fibers mentioned above being glove prints, so don't place too much hope on fingerprints. Of course, we will do everything possible Continue to work and strive to extract the fingerprints of the perpetrator. In addition, it is the fibrous substance, which has been mentioned before, so I won’t talk about it here. I will introduce it here, and I will ask Lao Zheng to add it.”

Lao Zheng: The previous introduction of Team Ke is our overall opinion on the entire technology, and I basically agree with it.Let me add the autopsy information here. It can be seen from the autopsy that the contents of the stomach were basically emptied, so it can be inferred that it was about five or six hours after the meal. Combined with our visits to the surrounding people, it reflects that the deceased had dinner at around 26 o'clock last night. Considering Taking into account factors such as weather and physical fitness, we therefore deduce that the crime occurred at 1-2 am on the [-]th.

Director Tang frowned and asked, "Are there no fingerprints of the suspect?"

Team Ke said: "It is still not completely sure whether there are fingerprints of the suspect. Judging from the current situation, it is very likely that the suspect was wearing gloves, and no bloody fingerprints were found at the scene. We will intensify our efforts in this regard."

Director Tang continued to ask: "Is there no trace of the suspect on the indoor ground?"

"I didn't find it, because the indoor floor is relatively dry, and it's also a concrete floor. We tried many methods, but we couldn't solve it." Old Zheng replied.

"If you can't solve it, please ask the provincial department for help. It must be resolved. As long as there is a glimmer of hope, you must make [-]% effort. Tomorrow morning, contact the provincial department." Without fingerprints, Director Tang became impatient, and the footprints were not satisfactory. It annoyed him even more.

Everyone is anxiously hoping that there will be solid traces and physical evidence in terms of technology. Seeing such a report on technology, my heart is almost cold.But they did their best.

When Director Tang lost his temper, the atmosphere in the meeting room became even more tense. Everyone felt a little depressed and kept silent.

Seeing that no one spoke, Director Tang said, "What about the field investigation team?"

Team Zhang said, "We investigated the deceased Ke Guifen. Her natal family was from Kejiazhuang Bay in this town. She was introduced to marry Liu Haiyang in August last year. We also found the introducer. After inquiry, Ke Guifen talked with several friends before marriage. , but the time of being together is relatively short, there is no emotional dispute, and she is relatively decent. She was pregnant three months ago and has a good relationship with her father-in-law.

Liu Haiyang has a relatively introverted personality and rarely socializes with others. He is known as a solid eye.Therefore, when I was older, I fell in love with Ke Guifen through someone's introduction and got married. After marriage, the relationship between the husband and wife is still good.There were no big fights, but occasionally a little quarrel.Neither of them had any enemies.There are no disputes in business dealings. The business is not very good, but basically I can make ends meet.

In addition, according to Liu Haiyang's father, Lao Liu, there should be about 2000 yuan in cash in the store. During the technical inspection, it was found in the bedding on the bed.

Lao Liu lost his wife in his early years and lived alone with his son. It was not easy. He got up early and worked in the dark every day. He was a hardworking person and an honest and responsible person.There is no major feud with others, and the relationship between neighbors is harmonious.The investigation of his family found no doubts. "

"In addition, the peripheral interview team visited relevant personnel in the town last night, and no suspicious circumstances have been found so far." Team Zhang added.

Director Zhang asked, "How did you visit?"

Team Zhang replied: "We asked our neighbors, and we saw Liu Haiyang and his wife after [-] o'clock last night. We didn't hear any quarrels and fights at night, but someone responded and heard a dog barking in the middle of the night."

"What time is the dog barking?" Director Zhang interrupted Team Zhang's speech and asked.

Team Zhang was at a loss for words, not knowing how to answer.

"1:40." A voice came out from the crowd.

Everyone glanced around and found that it was Xiao Liu from the Criminal Investigation Brigade.

Deputy Director Zhang said, "Tell me about the situation."

Xiao Liu: "I interviewed Liu Changping, who lives on the east side of the crossroads. He reported hearing a dog barking around 1:40 in the morning. He thought it was a thief, so he listened carefully, but the dog barked for a while. He didn’t call anymore, and he checked the time, and the time on his watch was 1:40. This time is credible.”

"Have you checked the time on Liu Changping's watch?" Director Tang asked.

"Not really." Xiao Liu's tone was obviously lower.

Everyone was silent and silent.

Director Tang turned his head to look at Team Ai, and asked softly, "How about the police dogs?"

Team Ai cleared his throat: "Talk to the police dog team."

Jing dog trainer Xiao Yang immediately said: "According to the smell source extracted on the spot, we let the No. 214 dog Xingda track it, and its walking route is along Provincial Highway [-], across the street, to the east of the town. You can no longer find the target.

We used the No. [-] dog radar to track again, and the situation with No. [-] police dog was basically the same, and the tracking conditions were also lost in the east of Zhendong.

Judging from the tracking of these two police dogs, the perpetrator should have walked out of the town along Provincial Highway 214 after committing the crime.Therefore, the east of Chenggong Town is the focus.

That's what our group is like. "

After Xiao Yang finished speaking, there was another silence, very quiet silence, no one made a sound.

"Is there anyone else to speak?" Director Tang said.

Seeing that no one answered, Director Tang said, "Then let me say a few words. I know that everyone has been busy all day today, and it is very hard. At this time, there is another meeting, and it will be held for such a long time. Everyone wants to sleep. But you sleep Is it right? Is this a murder case involving three lives? Is it a case of extermination? If the murder case is not solved for a day, we will have no peace for a day. It is only right to solve the case as soon as possible.

I just listened to everyone's work report. It may be the first day, and a lot of work has not been done.I can understand this, and I hope tomorrow's report will be more targeted.I would like to emphasize one point, what cannot be done at work is right and wrong, right is right, right is wrong, don't be busy for a day, and you can't get a thing done.Is that different from no investigation?The criminal police need to think more about it and ask more why.Criminal police is to be more thoughtful than others.

In addition, the person in charge should do more things by himself, not just listen to the report.Whether you have done anything, whether you have conducted in-depth investigations, I will come out as soon as I hear it.I would like to specifically remind comrades who are engaged in technology here, you must do everything possible, think of ways and measures, find evidence for me to identify the suspect, and do more research on the scene.That's all for tonight, everyone go to bed early, and work tomorrow. "

The meeting was dissolved in depression, and several team leaders recruited team members to study and deploy tomorrow's work.
