Chapter 5 3. On-site lectures

"Have you brought your notebook?" Lao Cheng asked me without looking back. "book?" "The first lesson of being a policeman is to bring a pen and a notebook with you." Lao Cheng freed up a hand and pointed to his head, "Even if your memory is good, there are times when you remember something wrong. As the saying goes, 'A good memory is worse than a bad pen. '." "I didn't bring it." I said helplessly, "Someone reminded me to prepare a pen and a notebook. I thought I would go to the bureau first today, so..." "So you didn't bring it?" Lao Cheng smiled, "Lesson 2, when you are a policeman, you must always keep one hand in case of emergencies. Open my bag, and there are spare pens and notebooks in the interlayer. Use them first. It’s my meeting gift for you.”

After I thanked him, I took out my notebook and pen, and the moment I closed the bag, I caught a glimpse of a photo in Lao Cheng's bag, which seemed to be a woman in a white dress. Lao Cheng said: "Now I will introduce the case to you, listen carefully and remember carefully." "Now?" I said helplessly, "in this bumpy car?" "Lesson 3, when you can't change the environment, try to adapt to the environment." The old man's voice was still serious, not at all joking. "Dong Yu, female, 20 years old, from Xinshi District, high school education, unemployed youth. On the evening of July 24, her sister Dong Le went to the street police station to call the police, claiming that Dong Yu had not returned home after going out to play cards in the evening. Netizens claimed that Dong Yu never came. Later, a fake pearl necklace was found about 3 kilometers away from his home. There was blood on the necklace, and the beads were scattered all over the place. The blood on the necklace was confirmed to be the same blood type as Dong Yu. Dong Le confirmed that the necklace belonged to Dong Yu. Dong Le recalled that before Dong Yu disappeared, he had borrowed some money from her to play cards and put it in his bag. Yu’s other belongings were not found. There were signs of a struggle near the scene.”

"Wu Xuejiao, female, 21 years old, from Beishi District, graduated from a technical secondary school, unemployed youth. On the evening of August 30, Wu Xuejiao went out to a dinner with her friends. At around 22 o'clock that night, Wu Xuejiao said that she had a headache after drinking too much. Leaving the banquet scene, but did not return home. His family members called the police at around 3:00 in the morning, and his whereabouts have not been known yet. I would like to add here that Wu Xuejiao is a person with strong vanity. In order to participate in the banquet, he borrowed it from others A very gorgeous dress. The local police found a torn piece of cloth at a bus station a few hundred meters away from the banquet site, suspected to be part of the dress."

"Ma Xiaoyu, female, 22 years old, works in a hotel in the town. On September 17, Ma Xiaoyu injured her leg and went to the hospital for a tetanus injection for fear of contracting tetanus. When he came back, he reported to the nearby police station. His whereabouts have not been found yet.” He looked back at me: "Remember?" "Yeah." I wiped the sweat from my forehead, it was really torture to memorize things in such a bumpy car. He said, "Now test you." "Ah?" I'm about to be tested, isn't it deliberately making things difficult for newcomers?

"Don't worry, it won't be particularly difficult," he seemed to see through my thoughts, "tell me about the similarities between these incidents." I tried to recall: "There are many similarities in these incidents. First, the victims were all young women who went out alone; second, the crimes took place at night or early morning; They disappeared together with the victim - of course, in the first case we found the necklace, but the victim's satchel and the money in the satchel were not found." "It's better than expected, and it's considered a good performance among newcomers." Lao Cheng actually gave me a rare compliment.

"The following questions are more difficult." I was taken aback: "Ah, there are still questions?" He smiled: "Relax, these things should be considered as a warm-up before actually starting to solve the case. Guess what is the murderer's motive?" Do you still want to weigh me?I scratched my head: "Then I really can only guess." "Maybe you can guess right." He shrugged. "You know what? When Team Wang first came, he was alone in the office. With just a few hours of reasoning, he solved an unsolved case a few years ago." It's broken."

I stuck out my tongue: "How can my reasoning ability be compared to Team Wang..." "You can't say that. He was just like you at the time, and he was also a rookie who had just graduated from the police academy. What about his age, he seems to be younger than you now." Before I came to report, the elders in my family, especially the elders who have worked in the public security system, had repeatedly told me to be down-to-earth, low-key, and not to express my subjective opinions casually, especially in front of the leaders, which would make me I seem very naive, and my unscrutinized views are of no help in solving the case.However, the old-fashioned words at this moment seem to have inadvertently stirred up my desire to win.Young people, especially young men, are always a little competitive.

"Then let me just say it," I cleared my throat, "Dong Yu, Wu Xuejiao, and Ma Xiaoyu have nothing to do with each other, and love and vendetta can basically be ruled out. As for kidnapping, it seems impossible, because so far the three of them have nothing to do with each other. No extortion letter has been received by anyone’s family. If it is human trafficking...it doesn’t look like it. Those who traffic people usually act in gangs. But this time it feels like one person acted, so I judged it to be robbery The murderer should be a short, thin man from the countryside."

Lao Cheng said, "How do you see it?" I said, "Dong Yu was wearing a necklace when the accident happened—although it was a fake pearl necklace, it was still a necklace, right? Her satchel with money was also missing. As for Wu Xuejiao, she was wearing The clothes hurt her, and the assailant thought she was a rich man; as for Ma Xiaoyu, she went out for injections, so she must have brought money with her. If it is said that the human trafficking gang wanted to plunder a few women, why did they arrest these 20 women? What about women in their early years? I remember the data showing that women under the age of 20 are more likely to be trafficked, because the younger they are, the less likely they are to escape.”

"That's not the point. I remember you said 'a short, thin man from the countryside' just now. I heard you right." The car was silent for a few minutes, Lao Cheng seemed to be patiently waiting for my answer. "Oh, it should be obvious." I closed my notebook and smiled at Lao Cheng. Lao Cheng seemed to be slightly shocked, and I saw an almost imperceptible smile on the corner of his mouth. I don't know if the smile represented comfort or ridicule. Team Wang had already left us far behind. We drove into a small town. Team Wang’s car was parked in front, and there were a few people standing beside him. Team Wang was questioning a young man. The young man was squatting with his head in his arms. On the ground, a look of despair.

Lao Cheng stopped the car and asked me to get out of the car together. "Speak." Wang Dui patted the young man's shoulder. "She was fine when she went out yesterday. In the evening, she called my work unit and said she had an engagement. That's it. She didn't come back after ten o'clock. She called her work unit, said she was not there, and called her friend. I said that the dinner party had already ended, so I felt something was wrong. I went to the restaurant where they ate, and it was closed. I searched for several places, but I couldn’t find it..." The young man spoke intermittently, and his mood fluctuated greatly. . "Does she have any relatives in the town?" Dui Wang asked. The man replied: "No." "Where's the enemy?" "No, she is usually very popular." "Has there been any strange people hanging around your house recently?" "No. Maybe there was, but I didn't notice." "En." Wang Dui nodded, nodding to Lao Cheng and me. After we passed by, he introduced in a low voice: "This person's name is Li Wei. His sister Li Xiaomeng disappeared last night. Before she disappeared, she had dinner with some friends. There is only one road from the place where she eats to Li Xiaomeng's house. I think this matter has nothing to do with The events that happened before are very similar." "Well, shall we take a look at that road?" "Let's go." Captain Wang asked the local police to lead the way, and we followed behind. Lao Cheng leaned into my ear and said, "When you're at the scene, don't touch what you shouldn't, and don't say what you shouldn't say." I nodded: "I know." Arriving at that street, Wang Dui couldn't help saying, "This place is really suitable for committing crimes." This street is about 3 kilometers long. On the south side is the Martyrs Cemetery, which is rarely visited by people. On the north side is a fireworks factory. An explosion occurred in this factory this spring.Up to now, only an empty factory building remains.Few people come to this area during the day, let alone at night. According to the local police, the street lights on this road were broken not long ago, and walking here at night is purely asking for trouble. If there were other options, Li Xiaomeng would definitely not go home this way. However, because there are few pedestrians, it provides certain convenience for the on-site investigation, and there is no need to block the scene. Lao Cheng reminded me "don't let go of anything of value" and followed Team Wang to Lunan.The cemetery on the south side of the road has no walls, and the grass in the cemetery grows very high, which is very suitable for Tibetans. After walking along the grass for about a quarter of an hour, Team Wang stopped: "I don't need to look at the north side of the road. The factory is surrounded by walls, and the walls extend to the end of the street. No one will walk from 3 meters away. How high is the wall to jump off and commit an attack, maybe you will sprain your feet. From the perspective of the terrain, we are in the best position now. The grass next to it is nearly one and a half meters high, which can easily hide people. You can see what's going on at both ends—if the light is good enough." Lao Cheng said: "Last night was sunny, and it was the sixteenth day of the lunar calendar, and the moonlight was very strong." Wang Dui searched in the grass, and suddenly bent down. Old Cheng and I went over to have a look. Wang Dui was staring at a very thin vine. "It appears to be a whole vine, but it's actually broken." Team Wang lifted it up, and the seemingly strong vine broke from the middle. "When I was a child, I used this plant as a rope to play with. It is very strong and can be easily broken. Someone should have stepped on it and stepped on it for a long time before it broke. There are a few footprints nearby, mature, Pay attention to taking pictures to collect evidence." He bent down and picked up some white ashes near the vines with tweezers. "The murderer is hiding here?" Wang Dui looked at the ashes against the sun, thought for a while, and said, "Let's look elsewhere." We walked straight along the street until we came to a T-junction where the street ended. Wang Dui suddenly bent down, and carefully picked up something with his gloved hands.It was a cigarette butt. We searched around and found a few more cigarette butts. Team Wang installed the cigarette butts one by one, and said to Lao Cheng, "It's different from the previous idea." Lao Cheng looked at me and didn't speak. We sorted out the things we had collected, and Dui Wang led us to ask Li Wei a few more questions, and then we returned to the police station together. When I arrived at the bureau, Lao Cheng took me to meet the leader, followed by several procedures for reporting, and finally took me to the police office. Wang Dui sat at the table, with his notebook spread out in front of him.Strangely, instead of staring at the book, he closed his eyes.His eyelids are moving, that is to say, the eyeballs are rolling under the eyelids, which is very strange.Only very few people become like this when they are engaged in intense concentration. Lao Cheng seemed unwilling to disturb him, and was about to take me out when Team Wang said, "Are you here?" He opened his eyes, with a tired expression on his face, as if he had done a particularly heavy labor. "Liu Shui, I have read your file, and you are a member of the team from today." Team Wang said to me, "This is the criminal police team, which is different from other institutions. We all have to go out to be busy, and eating and drinking is commonplace. There are still a few people in the team, but they all have official duties and have gone out to handle errands. Now it is up to the three of us to deal with this case. I don’t care if you are a fresh graduate or not, since The organization assigning you here is a sign of trust in your ability. In this unit, there are also many people who solved the case and caught the murderer in the first week of work. Although I know that situation is a special case, but I also believe that you will do a good job." This is a very subtle encouragement, but also shows a trusting attitude, which is conducive to the cooperation between colleagues.In many units, when a newcomer first joins the job, he has to go through a training period and an adaptation period. The leader has to observe him, study and judge his strength before assigning him a corresponding position.But this is not the case here. Newcomers must quickly enter the state on the first day of employment. I remembered that during the Soviet-German war, those Soviet children would be pushed onto the battlefield on the first day they had just taken off their school uniforms and put on military uniforms. Some people said that there is a certain similarity between the police force and the army,9 which is not entirely true. Unfounded. Lao Cheng said: "Today I explained some circumstances of the case to Liu Shui, and he also talked about his own views. I think it is very insightful, Liu Shui, please tell the captain your views." This time it was really tricky.My forehead was sweating, and I said to myself that you are too hasty to do it so old, my opinions are all nonsense, we two are killing time in the car and talking about it, and now we are handling a case, isn't this a waste of time. "This is not a waste of time." The captain said blankly. Absolutely!Can everyone on this team read minds? I repeated what I said to Lao Cheng during the day.While listening, the captain closed his eyes. When I finished speaking, Team Wang opened his eyes and nodded: "Innovative. Before the third missing person appeared, my opinion was the same as yours." I think the same, that is to say, what I think is correct? I asked, "Do you suspect that the suspect is a man of small stature?" He said: "The first missing person had wrestled with the suspect and left obvious marks on the scene. If the suspect was a tall and strong man, it would take little effort to deal with a woman. Since the first time, the suspect has chosen His target became drunk or a woman with an injured leg. Obviously, he had doubts about his own strength, so he could only find such a target. The disappearance of Li Xiaomeng made me more sure of my thoughts .” Wang Dui closed his eyes again, bowed his head in thought, as if his soul had come out of his body.A few minutes later, he murmured: "That's right, it's basically consistent with my initial deduction, but today, I completely overturned this judgment. The murderer is not one person, but two."
