Chapter 7 The sixth case: the soul of flowers under the moon

"But you said that there is a process of dying from blood loss, and it is very painful after being stabbed. How could you die like this without moving?" Chen Shiyu had already put on the survey equipment and stood behind me at some point. "By the way, you said last time that Xiao Yu liked Han Liang, didn't you?" Dabao said, "You said Han Liang, a playboy, how could girls like him? He is not as tall as Lin Tao, nor as long as Lin Tao." Handsome, this is unscientific." "I didn't say anything." I said while typing the testimonial in front of the computer, "You gossip, gossip, don't drag me in."

"Hey? You said that you, a dignified great mage, would renege on your debt after finishing it?" Dabao pointed at me. "I said, have you guys been free for the past two weeks?" Lin Tao said, "Discuss the affairs of the past and the moon early in the morning." "Flowers before the moon and under the moon are wishful thinking, right?" Dabao said, "It's not appropriate to use it here." Lin Tao was taken aback after hearing this, then smiled and said, "It makes sense for you to say so." As soon as Lin Tao finished speaking, Chen Shiyu walked into the office.She hung her backpack on the hanger, stroked her hair, sat at the desk and turned on the computer, and asked indifferently, "What are you talking about? What's under the moon?"

Lin Tao looked at Dabao reproachfully. Dabao blushed and stammered, "Ah? What? That...no...no." I still did not take my eyes off the testimonial on the computer screen, and said: "We are discussing ghost stories. It is said that under the moonlight in July and a half, there are always supernatural events happening." My original intention was to use ghost stories to dispel Chen Shiyu's questioning about our topic. Who knew that Chen Shiyu's two big eyes lit up immediately, and said, "Do you have any ghost stories? Tell me too." "Uh..." I was speechless.

Lin Tao said with a pale face: "Can you stop talking about ghosts and gods? It's scary." Chen Shiyu covered his mouth and smiled: "You said you are a big man, in broad daylight, why are you afraid of these things? It's shameful." "That's what he is." I laughed too. Suddenly, the phone rang.Chen Shiyu grabbed the receiver. After listening for a while, Chen Shiyu hung up the phone, and said quietly: "President Chen came to give an order, saying yes..." "Master." I interrupted Chen Shiyu, put on the airs of the section chief, and said, "We are all called Master Chen, and you are a member of our team. You must also follow this title."

"No." Chen Shiyu tilted his head and said, "He is a forensic doctor, and I am an investigator. In terms of investigation, maybe I am his master." "He's also outstanding in detective work, okay?" After I was rejected, I felt a little embarrassed and blushed, "You must respect him and call him Master!" "I call him Mr. Chen because I respect him. Why do I have to call him Master? I'm not Bajie." Chen Shiyu said with a provocative smile. Lin Tao, who has always been proud, has always been a peacemaker recently, saying: "Hey, little feather, even if we are Journey to the West, you are still the white dragon horse."

Dabao looked left and right, and said, "Isn't there a mistake? There is a case, what titles are you still arguing about here?" I said nothing. Chen Shiyu said: "Mr. Chen said that a naked female body was found near a flower garden in Tingtang City. It is currently judged to be a homicide. The local forensic doctor asked the provincial department for support." Chen Shiyu deliberately emphasized the word "Mr. Chen". Watching me start to tidy up the survey box, Dabao made another iconic expression and raised two fingers. "Stop, let's go!" I abruptly blocked back the eight words that Dabao was about to blurt out.

I have already expressed my approval for Chen Shiyu's professionalism, but I still cannot accept her spirit of disrespecting the old and caring for the young.So, along the way, I didn't talk to her.Regardless of Lin Tao's gaze, she chatted non-stop with Han Liang along the way. When the police car drove down the intersection of Tingtang Expressway, we saw the head of the annual detachment and Zhao Yong standing in front of a police car with lights flashing, waiting for us. I got out of the car, shook hands with them enthusiastically, and said, "Brother Yong, I haven't seen you for a long time. What, your technical training at the provincial department is over?"

Zhao Yong shook his head and said, "It's over early. There are only three or four forensic doctors in the family, and they can't run to the scene, let alone seven or eight hundred injury appraisals a year." "Fortunately, you don't have many murders." I said with a smile. Zhao Yong said: "Fortunately, this is a murder case, so you just said that. Otherwise, your crow's mouth should be passed down as a 'good story' in Tingtang." "What's going on with this case? Any idea?" I asked. Zhao Yong shook his head and said, "Let's go to the scene first, and then talk about it in detail."

Tingtang City is a beautiful city like flowers, and you can see flowers in full bloom along the way.Flowers always have a place to grow, so almost all the land around Tingtang City is occupied by flower gardens.The local people live a prosperous life by growing and selling flowers. After the police car drove past the west gate of Tingtang University, the bustling scene outside the car window disappeared instantly, replaced by endless stretches of flower gardens.At this time, it is the turn of spring and summer, and the spring scenery full of flower gardens makes people linger and forget to return.

Women always like flowers, Chen Shiyu leaned on the car window with an intoxicated expression on his face.Lin Tao looked at Chen Shiyu who was leaning on the car window with a look of intoxication. The police car stopped on the side of a road about three kilometers away from the west gate of Tingtang University. On both sides of the road, there are still endless beautiful flowers and fragrances.From a small road extending westward perpendicular to the main road, you can enter the center of the flower garden. In the center of the flower garden, many policemen in uniform are busy.Fortunately, this is a very remote place, and there are almost no crowds on the side of the road.

Warning tapes are set up at intersections.Because this path is the only passage that can lead to the main road, and the flowers in the flowerbed have no obvious traces of trampling, so it is very likely that the murderer left traces on the path and intersection.So, the alert range extended to the place where we got off. Chen Shiyu squatted on the side of the road as soon as he got out of the car, stretching his neck to sniff. "It's a man's job, but he's actually a woman." Han Liang squatted beside her with a smirk on his face, picked a flower from the flower garden, handed it to Chen Shiyu, and said, "Here, I'll give it to you." Chen Shiyu's cheeks were flushed. Lin Tao patted Han Liang on the back of the head and said, "Are you here to work or to cause damage? Be a civilized person and do things in a civilized manner." I put on the survey equipment, carried the survey box, and walked along the path between the flower gardens with Brother Yong to the depths of the flower garden. After walking about 500 meters, I saw the second layer of warning tape. "This is the central site." Yong Ge pointed to the side of the path, and said, "In the middle of the baselines of the two greenhouses, there is a naked female corpse. Here, there." In winter, the flower garden is composed of many greenhouses arranged in parallel.As the weather gets warmer, the plastic sheeting of the greenhouses has been removed, but the baseline between each greenhouse can still be seen.Among the many red, yellow and yellow flowers, a corpse was lying face up on the ground, with a little dirt stained on the white skin of the chest and abdomen. I looked back at the place where we got off the car. Han Liang was still squatting on the side of the road with Chen Shiyu admiring the boundless flowers. Lin Tao was fully dressed and approached me along the path. Look for tracks that may be left on hard dirt surfaces. I slowly approached the corpse to avoid stepping on the beautiful flowers, squatted beside the corpse, picked up one arm of the corpse, tried the rigor of the upper arm of the corpse, and said: "The rigors of the large joints are fully formed." After finishing speaking, he tried the rigor of the ankle joint and knee joint of the corpse, and said, "It should be the hardest time for rigor rigor. There should be at least twelve hours before death." Dabao raised his wrist and looked at his watch, and said, "It's ten o'clock in the morning, so he died before ten o'clock last night." Zhao Yong said: "We came here at eight o'clock in the morning when we received a report from the owner of the flower garden, and took the temperature of the body. The rectal temperature was 26.5 degrees Celsius. According to the law that the hour drops by one degree, and ten hours later, it drops by 0.5 degrees every hour, the deceased should have been dead for eleven hours. That is to say, he died on May 20, around nine o'clock last night. " I nodded and began to perform a superficial inspection of the body.The deceased looked about eighteen or nineteen years old, except for a pair of socks and a sneaker on his right foot, he was completely naked.From the skin of the chest, abdomen and limbs exposed in the center of the flower, there is no trace of damage. I looked at the lower back of the corpse, and the plaques were not obvious, and the nails and lips of both hands were not cyanotic either. "If it wasn't for the rigor formation, I would really have thought it was a Sleeping Beauty," I said, "Why are the plaques so unnoticeable?" Zhao Yong held onto one side of the corpse, turned the corpse into a side-lying position, and said, "Look." At this moment, I was taken aback and said, "It turns out that the injury is on the back!" There was a large wound on the left side of the female corpse, and the blood scab around the wound had solidified, forming a bloody pattern on the fair skin of the back.Taking advantage of Zhao Yong's opportunity to support the corpse, I fiddled with the soil under the corpse.Because this is the soil for planting flowers, it has been turned over and is very soft.A large piece of the soil under the corpse was soaked in blood. No matter how I dug small pits one after another, traces of blood stains could be seen on the soil around the pits. "Any blood stains in the surrounding dirt?" I asked. Zhao Yong shook his head and said, "Before you came, we focused on the soil around the roots of the flowers and the leaves of the flowers, trying to find some blood, but there was no blood, not even dripping blood." "Very good." I said, "If it were me, I would also first inspect the surroundings of the corpse, looking for some bloodstains that can indicate the trajectory of the deceased after the injury." "But no bloodstains were found. All the bloodstains were confined to the soil under the body of the deceased. Don't you find it strange?" Zhao Yong said. I smiled slightly and said, "It's not surprising. Combined with the fact that the deceased fell down by the side of the path, and there were no obvious and unnecessary stampede marks on the surrounding flowers, it means that she fell directly to the ground after being stabbed and never moved again. That's all." "But you said that there is a process of dying from blood loss, and it is very painful after being stabbed. How could you die like this without moving?" Chen Shiyu had already put on the survey equipment and stood behind me at some point. This was the first sentence Chen Shiyu voluntarily said to me after we had an argument in the morning. It was obvious that she was eager to learn. Dabao was afraid that I would ignore her and cause embarrassment, so he rushed to say: "Oh, that's right, have you seen her injury? It's around the fourth rib on the left back, where the heart is. After a person's heart is punctured, different people will have great individual differences." "Individual differences?" Chen Shiyu asked, "What are individual differences?" "Individual differences are that each person's constitution is different. The same injury or the same environment will cause different reactions." In order to ease the atmosphere, I said before Dabao answered, "After the heart ruptures, most people will not die immediately, but will die. Die quickly; a few people can run for hundreds of meters before they die; and a few people may suffer cardiac arrest and die immediately." "Oh," Chen Shiyu nodded and said, "She is the last case." "The murderer's knife was steady, accurate and ruthless," Dabao said. I shook my head and said, "It's also possible that a blind cat meets a dead mouse. In the middle of the night, a single knife can kill a person in motion. Professional killers can't guarantee 100%." "Yesterday was the thirteenth day of the lunar calendar. The weather was fine and the moon was bright and the stars were rare." Zhao Yong said, "We have obtained the weather data. At around 9 o'clock last night, this area was illuminated by a bright moon, and the visibility was very high. .” "Hey, that's really the end of the year." Lin Tao had already surveyed our back at this time, he straightened up and twisted his waist, and said. The on-site survey of the ground is very hard, because the surveyor has to constantly bow his waist, looking for traces of the ground.Over time, problems such as lumbar muscle strain and herniated intervertebral discs have become persistent problems for field investigators. "I said that your primary school Chinese was taught by the physical education teacher." Dabao sneered, "Hua Qian Yue Xia is to describe two loving people, right? There is only one person here, a woman, or a naked dead woman, where? Did you come here?" "How do you know there isn't a naked man's body around?" Lin Tao was wearing a mask, but I could imagine the expression behind his mask baring his teeth. "Please, Section Chief of Lin University." Zhao Yong said, "Our place is safe and secure. One corpse is enough pressure. If two corpses come, we will be out of breath. This is obviously a scene of sexual assault. " "I think so too." Dabao said, "Even if the murderer is a man, he is also a vicious man. Where did Beauty and the Beast come from?" I saw them discussing the topic of the morning cheerfully, and secretly glanced at Chen Shiyu.At this moment, Chen Shiyu was also looking at me with a puzzled look on his face. "You said it was sexual assault, is there any basis?" I coughed twice to ease my embarrassment, and turned to Zhao Yong. Zhao Yong shook his head and said: "When measuring the temperature of the anus, we checked the perineum of the deceased, and there was no damage. The vaginal swab was tested for sperm spots, and it was also negative." "Oh, I thought you confirmed that this was a sexual assault scene," I said. Zhao Yong stared and said, "Naked female corpse, isn't it sexual assault? Could it be that in this night when the temperature is 17 or 8 degrees, they will still freeze to death? Take off their clothes abnormally? There are no clothes around." "Undressing does not necessarily mean sexual assault. We cannot judge the nature of the case based on whether the corpse is clothed or not." I said, "By the way, you just said that there are no clothes around? Have you conducted a peripheral search?" Zhao Yong said: "Not yet. What I said is that there are no clothes next to the corpse." I nodded and said to Lin Tao, "How is your investigation going?" Lin Tao said: "No footprints were found." "Ah?" Chen Shiyu exclaimed, "How could it be? I just heard from the investigators that one end of this small road is connected to the main road, and the other end is a dead end. There are no traces of trampling on the flowerbed, and there are no footprints on the small road. The murderer flew out." ?” "Your thinking is wrong." Lin Tao corrected Chen Shiyu's point of view, "The principle of on-site investigation is to find something and then verify it; instead of judging what will be found based on some simple cases. For example, although this small road is a dirt road, But because it hasn’t rained for a long time, and the irrigation can’t be done on the road, the soil is very hard. We all know that on the smooth ground, you can find dust and layered footprints, but on dirt roads, you can only find three-dimensional footprints. Then it is impossible It is quite normal that dust plus layer footprints and three-dimensional footprints cannot be found on sunken dirt roads." Chen Shiyu rolled his big black eyes, as if he didn't understand. Lin Tao smiled slightly, and said softly, "I'll teach you in detail when I have time." "There is nothing at the scene, are we going to have an autopsy?" Chen Shiyu asked. I shook my head and said: "The standard for the completion of the site investigation is that all the places that can be surveyed have been surveyed, and no other suspicious points have been found. This scene is far from meeting the standard for the completion of the site investigation, because the deceased's clothes and a shoe have not found." "Then what should we do?" Chen Shiyu continued to ask. I turned my head and said to the annual detachment leader who didn't say a word behind me: "The annual detachment leader, you can inform the funeral home that the car is coming, and take the corpse to the autopsy room first. There is really nothing to find around this corpse. Our next job is to cooperate with your criminal police colleagues in Tingtang City to search the surrounding scene." The head of the annual detachment was less introverted, just nodded slightly, then went to the side and took out his mobile phone to arrange work. I stood up, patted the dirt on my gloves, and said, "We walked along the path, admiring the flowers, and conducting a peripheral search. The focus of the search was the clothes that the deceased might have discarded in the flowerbed, and the possible Existing trample marks." Several people nodded, and walked along the road where a car could pass, to the depths of the endless flower garden to the west. A few of us technicians carefully searched for suspicious signs in the flower garden while walking, while Chen Shiyu strolled alone holding a flower with his head bowed. Dabao poked Lin Tao with his elbow and said, "Did you see that flower she pinched was given to her by Han Liang just now?" Lin Tao glanced back, glared at Dabao and said, "You are really like a woman, gossip, pervert, pervert!" Dabao laughed loudly and said, "Don't vent your anger on me." I said seriously: "Seriously look for it, don't be distracted." After walking a hundred meters, we found something dark in the middle of a pile of plastic sheeting that had been dismantled and neatly folded on the south side of the path. "Found it!" I exclaimed happily, "I saw a sneaker!" The clothes are not deliberately hidden in the center of the plastic sheet, but scattered here in a mess.However, the pile of plastic sheets is half a person's height, and the area is not small, so the clothes scattered here were not found by the preliminary investigation police. Dabao squatted on the side of the road, picked up the pair of underwear closest to the side of the road, and looked around. I took out a few evidence bags from the investigation box and said: "Don't look at it yet, fix the camera, then put it in the evidence bag, go back and look slowly, don't be polluted by mud here." Lin Tao took out a stack of number plates from the survey box and numbered the clothes scattered in the pile of plastic sheets; Chen Shiyu picked up his camera and took pictures of the clothes.After several cases of tempering, the cooperation between the two is very tacit. Soon, the clothes were photographed and fixed, and then extracted into evidence bags. "I'll keep walking." Lin Tao said, "Little Feather, come with me." I nodded, still squatting next to the plastic sheet, watching the soil on the ground. Dabao said: "There are no traces of trampling on the flowers around the clothes, and there are no footprints on the soil." I said, "Yeah, I'm also looking at these issues. Now the question comes: Why did the deceased take off his clothes here, stripped naked, and then died a hundred meters away? The fact that a sneaker was dropped from the deceased From the indications, she should be flustered when undressing, not calm. The undressing caused the shoe to fall off, and the other shoe was not taken off, and the shedding shoe was not put on. The point is, the place looks calm , without any signs of resistance or fighting. What kind of force made a girl obediently take off her clothes in the wilderness?" Neither Dabao nor I said anything, we squatted beside the pile of plastic sheets in a daze. Suddenly, Lin Tao's shout came from a distance, interrupting our thoughts. I stood up and looked west.At this time, Lin Tao and Chen Shiyu were already three or four hundred meters away.Because the location is empty and the surroundings are very quiet, Lin Tao's voice reached our ears through the air. Dabao and I ran quickly to Lin Tao. Following Lin Tao's fingers, we saw a brick hole twenty meters to the north of the road. It was dark and we couldn't see inside. "What's the matter?" My muscles tensed. At this moment, Lin Tao's face was pale, and his lips were trembling slightly. Seeing that Lin Tao couldn't answer for a moment, Chen Shiyu said calmly: "When we walked to a place about 20 meters away from here just now, we saw traces of being trampled on in the middle of the flowers on the north side of the road. Following the stampede traces, we After walking for more than 20 meters, I saw the entrance of the cave. The traces of trampling disappeared at the entrance of the cave.” "What's so scary at the entrance of the cave? It's in broad daylight." I looked at Lin Tao suspiciously. Lin Tao was still trembling and did not answer. I was on the road, walking back along the stampede about three meters away from the side of the road.The stampede was evident, about the width of a man's shoulders. I walked back to Lin Tao's side again and said, "Don't be dazed here, go and see if there are any footprints that can be used as evidence in the trampled marks. The soil in the flower garden is different from the soil on the road. It is soft and has May leave a three-dimensional footprint." Only then did Lin Tao regain his senses, walked into the flower garden, and squatted on the ground to look at the traces. The head of the annual detachment and the director of the police station in the area who heard Lin Tao's shouts also ran to our side at this time. The head of the annual detachment said, "What's wrong? What happened?" I smiled and said, "Lin Tao likes to make a fuss. It's nothing. I just found stampede marks here. I don't know if it can be related to this case." "Also, we found a hole, but we don't know what it is." Chen Shiyu pointed to the brick hole. The director of the police station said: "Oh, that's an air-raid shelter. It was left over before liberation, and it was a soil hole dug by ordinary people. Later, the owner of this flower garden repaired it and used it as a cellar. We also asked, and they I don’t usually use this cellar.” At this time, Lin Tao walked out cautiously from the flowers, his face still pale, and said, "Look, there are no footprints." "Why are there no footprints?" Chen Shiyu asked, "It's not the texture of the ground this time, is it?" Lin Tao said: "The flowers are planted too densely. When you step on it, you will all step on the fallen flowers. At most, you can only see the outline of the footprints on the land, and you can't see the pattern of the soles, so there is no identification value. Even It is impossible to judge how many people left behind." It was about the same as I expected, so I didn't question it.I told the head of the annual detachment: "The traces of stampede disappeared at the entrance of the cave. We want to go into the cave to have a look." "No, no, if you want to go in, you can go in, but I won't go in." Lin Tao shouted. Chen Shiyu said contemptuously: "Really, a big man, what kind of black hole is he afraid of? I wasn't afraid at first, but you were so frightened that you almost died of fright." The head of the annual detachment took out his pistol vigilantly and said, "What? It disappeared at the entrance of the cave? Could the murderer be hiding in the cave?" The head of the annual detachment said this, reflecting his rich practical experience as a veteran criminal policeman.It is true that many murderers hide around the scene after killing people, and may even cause harm to the investigating police. Hearing the reminder from the head of the annual detachment, my heart tightened, and my back felt a little cold.I saw that Chen Shiyu also showed a nervous expression. The director of the police station also took out his pistol and said, "I'll go in and have a look." The head of the annual detachment nodded, and approached the entrance of the cave side by side with him. After loading the pistol and holding the flashlight in the other hand, he slowly moved down the concrete steps extending to the entrance of the cave. The few of us had no weapons, so we had to wait at the entrance of the cave in fear. After about fifteen minutes, without hearing the gunfire, the head of the annual detachment and the director of the police station walked out of the cave again. All of us breathed a sigh of relief. The head of the annual detachment put away his pistol, and said lightly: "There is a male corpse below." "Huh?" Several of us called out at the same time. "What male corpse? Is it related to this female corpse case?" Dabao shouted. The head of the annual detachment nodded and said, "I think it should be related." "Let's go down and have a look." I adjusted my gloves and survey cap and said. "No, no, I won't leave." Lin Tao's face was pale, his lips trembling. I didn't say anything, and walked into the entrance of the cave together with Dabao, Zhao Yong, and Chen Shiyu. Down the hole are cement steps that were later repaired. Each step of the steps is very narrow and somewhat uneven.After walking down the steps for more than a dozen steps, some wipe-like blood stains were seen on the surface of the steps, almost on every step.Walk along the steps for more than 20 steps, and you will come to the bottom of the cave.The bottom of the hole is very narrow, that is, it can accommodate three or four people.In the middle of the bottom of the cave, lay a male corpse. Because Lin Tao didn't dare to come down, we brought a trace inspector from Tingtang City down to the bottom of the cave.After investigation, the trace inspector decisively judged that there were no fresh footprints at the bottom of the cave.This time it was not because of the problem of the ground structure, but it was certain that no one else went down to the bottom of the cave except the dead. "The corpse was thrown here?" Dabao said. Zhao Yong shook his head and said: "There is no trace of blood on the stampede, nor is there a trace of dragging. I think the deceased should have walked into the cave by himself." "That's right." I said, "Don't forget that the bloodstains on the steps started from halfway up the steps, and they were wipe-like bloodstains. This shows that the dead person probably rolled into the hole." "It makes sense." Zhao Yong said, "But this needs an autopsy as proof. It's too dark here to see clearly, so hurry up and transport the body away. We need an autopsy as soon as possible to find out the truth." I nodded and walked around the bottom of the cave. After making sure that there was nothing or traces in the cave, I went back to the entrance of the cave. Lin Tao was standing in a daze among the flowers. I took off my gloves, patted Lin Tao on the shoulder, and said, "The title of Crow's Mouth can be passed on to you in the future." Lin Tao's complexion improved a lot, and he said, "What? Did I really hit the spot? There was a naked male corpse inside? Did it really happen?" I shook my head and said, "It's not naked, but it is indeed a male corpse." "Then I can't be called Crow's Mouth." "Isn't this a crow's mouth? Then what is it called a crow's mouth?" Bickering with Lin Tao, we walked quickly back to the main road together, got into a police car and headed for the funeral home. When we arrived at the autopsy room of the Tingtang City Public Security Bureau, the female body had already been placed on the dissection table, and bags of clothes were also placed in the evidence room beside it.The male corpse hadn't arrived yet. "Let's start first." As I said, I put on a disposable autopsy suit and began to perform an autopsy on the female body. Because there are few injuries on the body, the dissection work is very simple.The knife on the dead man's back was her fatal wound.The knife just entered the chest cavity from the gap between the third and fourth ribs, passed through the lungs, and pierced the heart.Because the knife entered the chest sideways, no marks were left on the ribs. There was not much blood in the chest of the deceased. On the one hand, a lot of blood flowed into the soil, and on the other hand, the cardiac arrest was caused by a ruptured heart.Corpses that die quickly will have less bleeding.For example, in the corpses that fell to death, there was only a small amount of bleeding at the fractured ends and the ruptured internal organs. This discovery also explained why there was no trace of struggle at the scene, which verified my inference. "The deceased's hymen was intact." Dabao said, "he must have never been sexually assaulted." "So, we cannot classify this case as a sexual assault case." I said. Zhao Yong said: "That's not necessarily the case. Maybe it's because the murderer stabbed the deceased down with a knife, so he didn't continue to commit sexual assault?" "The reason why the murderer was able to stab the deceased was because the deceased died quickly, so people without professional knowledge may not realize that the deceased is dead." I said, "If it is a murderer with a clear purpose of sexual assault, he may continue to commit suicide. Behavior." We did not continue to argue about this issue. Dabao silently dissected the head of the deceased according to the dissection procedure.Zhao Yong said: "Then shall we take out the pubic symphysis of the deceased to pave the way for the next step in finding the source of the corpse?" I shook my head and said, "No hurry, the deceased's clothes haven't been checked yet, let's try to leave a whole body for the deceased. After all, she was a little girl who loved beauty when she was alive." Dabao and Zhao Yong were cooperating to saw open the skull of the deceased, and I went to the evidence room to examine the deceased's clothes. All the clothes of the deceased were lined up by me and placed on the physical evidence examination table.A sneaker, a pair of black lace panties, a pair of jeans, a bra, and a light, long-sleeved cardigan. Several garments are intact, and the backs of the cardigans are intact.Several pieces of clothes are in a naturally rolled up state, which is consistent with the shape of taking off clothes by themselves.The front pockets of the jeans showed some signs of being turned inside out, and a student ID card was in the back pocket. I flipped through my student ID card, and the person in the photo was smiling like a flower. "Niu Qinglan, born on May 20, 1994, a member of the Communist Youth League, a freshman in the Foreign Language Department of Tingtang University." I read silently. With a heavy heart, I put all my clothes back into the evidence bag and walked back to the anatomy area. "The poor girl," I said, "was killed on her eighteenth birthday." "Huh?" Everyone looked at me together. I picked up a physical evidence bag containing a student ID and said, "I have an ID card, so let's inform the investigation department to conduct a peripheral investigation. The girl is a freshman in the Department of Foreign Languages, and yesterday was her eighteenth birthday." Everyone's mood became heavy in an instant, and there was no sound in the dissection room. I went on to say: "I looked at the clothes, and they were all rolled up naturally, as if they had been taken off by themselves. There were no wounds or blood on the back of the jacket, so it was ruled out that someone killed someone and then took off his clothes. He took off his clothes first, and then was attacked." "How can you tell that you took it off yourself?" Zhao Yong asked. I said: "First, we have opened all the limbs and joints of the deceased, and found no threatening or resisting injuries; second, the clothes are in a natural rolled-up state without any tears; third, the clothes have no signs of being cut by sharp objects. You think, the murderer has a knife, if the clothes were not taken off by the deceased himself, the murderer might forcefully tear them apart or cut them open with a knife." Everyone was silent again.There was only the sound of needle clamps clamping the steel needle when Dabao and Zhao Yong were stitching up the corpse. We didn't draw conclusions because there was a male corpse waiting for us outside the autopsy room. The hour hand has already pointed to twelve o'clock, and we didn't feel the slightest sense of hunger, so we decided to continue the autopsy on the male corpse. The male deceased was also a boy of eighteen or nineteen years old, fully clothed. The deceased was wearing a shirt on his upper body, a pair of casual trousers and a pair of underwear on his lower body, and the bottom of a pair of leather shoes on his feet was covered with mud. We gradually took off the dead man's clothes. When Dabao and Zhao Yong were examining the dead man's form, I carefully looked at every piece of the dead man's clothes.It was found that in the pocket of the casual trousers worn by the deceased, there was some dirt, a student ID card, and seventy or eighty yuan. "This is also a student." I called out, "Lu Hua, born on December 1, 1992, a member of the Communist Youth League, a sophomore in the Chinese Department of Tingtang University." "Yo, these two people are not in a relationship, are they?" Lin Tao said, "This time it is really the same time?" I said nothing and joined the ranks of autopsy. The dead man's rigor was also very hard, depending on the strength, it was similar to Niu Qinglan's, and the time of their death was also very similar.The deceased's face had large bruises, all of which had obvious life reactions.When you touch the skull of the deceased, you can feel the bone fricative. "He may have died of traumatic brain injury." Dabao said. I didn't talk, I was watching the peeling of several parallel epidermis on the neck of Lu Hua's corpse. Dabao and Zhao Yong quickly inspected Lu Hua's chest and abdomen, and said: "There is no damage to the chest and abdomen, and there are no fractures in the limbs. There are only some scratches on the two palms and the back of the hand." I nodded, opened the scalp of the deceased, and started the electric craniotomy saw. "The fatal injury of the deceased was indeed on the head." I said, "Blunt trauma. Below this small rupture in the forehead, there is a depressed fracture. There is a large subdural hematoma and a large subarachnoid under the fracture." The cavity is bleeding, and the brain tissue is also contused. This injury is not light." As I spoke, I removed the brain tissue of the deceased. "Hey, the brain tissue of the occipital lobe also has contusions and a small amount of bleeding!" I said while looking at the occipital scalp of the deceased. "I checked the occipital scalp just now, and there is no damage." Dabao said, "It must be a concussion injury." Everyone was silent again, each combining the injuries on the two corpses in their hearts, and analyzing the possible history of the case. "I see." Dabao spoke first, "Niu Qinglan was stabbed to death, and Lu Hua ran into an air-raid shelter by mistake and fell to his death!" "I agree." Chen Shiyu said, "First of all, there are no footprints at the exit of the small road, maybe no one has gone out; secondly, there was a moon that night, and judging from the slope of the air-raid shelter, the moon can only illuminate the entrance of the air-raid shelter more than a dozen times. The position of the first step, the bloodstain also started from there, indicating that after the deceased entered the air-raid shelter, it was illuminated by moonlight, and because there was no moonlight, he stepped on the air and fell down." Zhao Yong said: "The analysis makes sense. After all, there is no injury on Lu Hua's body, and the injury on the head is also a concussion injury, indicating that the possibility of his own fall is relatively high. Supporting this point of view, there is no one else at the bottom of the air-raid shelter. At least Lu Hua can rule out homicide." I said, "Then why did Lu Hua kill Niu Qinglan? Sexual assault?" "I can't rule out the possibility." Zhao Yong said, "Maybe he also killed Niu Qinglan unintentionally. After the murder, he would be so frightened and run wildly for several hundred meters, eventually dying at the bottom of the cave." My mind was suddenly a little confused, and I didn't continue to speak. "Hurry up, I'm hungry." Chen Shiyu said suddenly.Maybe she felt that the case had dawned, maybe she recognized that it was a self-produced and sold case, so she was a little relaxed. This relaxation, the first thing that showed was hunger. After all, we came out early in the morning and had already worked for five years. Hour. "You're really good." Lin Tao said, "You can actually feel hungry watching the autopsy!" "Fuck you." Chen Shiyu scolded. 大宝看看墙上的挂钟已经将要指向两点钟，便抓紧了手上的缝合动作。 我一直没有吱声，默默地配合大宝把尸体缝合好，然后放进冷库冷冻，和大家一起去吃了份简餐，然后直接赶往位于汀棠市公安局大楼顶层的指挥中心。专案组设在那里。 调查工作仿佛开展得很顺利，侦查员正在向专案组介绍已经掌握了的情况。 “根据从法医那里得来的身份信息，我们开展了调查。”侦查员说，“首先，通过照片比对，可以判断两名死者是牛青岚和卢华，两人都是汀棠大学的学生。经过调查，两个人是在今年校园歌手大奖赛上认识的，卢华当时拿了第一名，牛青岚拿了第三名。根据周围同学们的反映，两人从那次大奖赛后，就开始频繁接触。牛青岚的室友反映，卢华对牛青岚疯狂追求，牛青岚一直没有明确两人的关系。昨天晚上，室友们准备给牛青岚过生日，牛青岚说出去和卢华一起过。两人大约五点半在食堂吃完饭，就一起出去了，一整夜没有回来。现在大学生都很开放，所以室友们也没有在意牛青岚整夜未归这件事，两人上午也没来上课。” “根据汀棠大学西大门监控显示，”另一名侦查员说，“两个人昨天下午六点左右，从西大门出学校，向案发现场方向走。还有，因为西大门外就是花圃，所以很多谈恋爱的大学生喜欢选择在这地方缠绵。西大门门卫反映，必须有本校的学生证，他才放学生出门、允许学生进门。所以两名死者的身上都携带了学生证。” “法医这边，”我低声说道，“我还没有完全想好。客观介绍一下尸检状况吧。根据尸体检验还原现场。死者牛青岚是在塑料布附近自行脱去了衣服，然后在一百米开外的花圃里被刺身亡。这一刀在背后，自己不能形成，肯定是他杀。这一刀直接刺破心脏，导致心跳骤停，死者没有挣扎直接倒地死亡。死者在生前和死后都没有遭受过性侵害。死者卢华，损伤主要是头面部和双手的擦伤，致死原因是颅脑损伤。这个颅脑损伤是对冲伤，结合现场情况，他应该是在进入防空洞后，因为光线陡暗，一脚踏空形成的。这个过程，结合花圃里的踩踏痕迹，可以反映出他当时的惊恐心情。” “那就很明确了。”年支队长舒一口气，说，“两名死者在现场附近谈恋爱，然后牛青岚自行脱去了衣服。可能在缠绵的过程中，不知道发生了什么口角，所以卢华一时冲动杀死了牛青岚。因为惊恐，他没有跑回学校，而是往反方向跑去，结果误入防空洞，摔死了。” 会议室里议论纷纷。 我愣了一会儿，说：“怕是没有这么简单。” 大家迅速安静下来，听我发言。 我说：“年支队长的说法，可能是大多数人的想法，也可以解释两名死者的不同死因。但是这种想法中，还存在着很多疑点。” “哦？”年支队长说。 我说：“第一，牛青岚还是个处女，这么容易就在荒郊野外，在男朋友面前脱衣服？不合常理。第二，如果二人是在缠绵，哪有女孩脱光了衣服，男孩衣着完整的道理？第三，牛青岚只穿了一只鞋子，感觉这个脱衣服的过程也是很慌乱的，不像是在谈恋爱。第四，如果是卢华杀了牛青岚，那么凶器去哪儿了？第五，一般人杀完人后，即便是激情杀人，杀人后惊恐，第一反应也应该是往熟悉的地方逃窜，哪里有往不熟悉的野外逃窜的道理？” 年支队长默默地点点头，说：“确实，你这五点都很合理。尤其是凶器，应该是个单刃的宽匕首。这样的凶器，谈恋爱的时候不会带着，更不会无缘无故地消失。” “那这个现场，能告诉我们什么呢？”赵永沉思道。 我打开投影仪，慢慢地翻动着尸检照片，最后停在卢华尸体颈部的一张照片上，说：“还有，这一处损伤大家可以看看。” 这处损伤就是我在尸检前仔细观察的损伤。这处损伤是由七八条细条形的划痕组成的，生活反应明显，和面部的擦伤有些相连。 “这处损伤，乍一看是面部擦伤的延伸。”我说，“但有两个问题。第一，这是颈部，没有骨骼的衬垫，不应该形成这么规则的擦伤。第二，这几处损伤的周边明显要比面部擦伤整齐许多。所以，我认为这不是摔跌时形成的梳状擦伤，而是锐器刃边形成的小划痕。” “你是说，这几条是损伤，是威逼伤？”赵永说。 我点了点头，说：“鉴于这些疑点，加之现场的特殊和死者衣着的特殊，我一时半会儿还没有想好如何进行下一步分析。” “那就不强人所难。”年支队长说，“现在是三点多，你们回去休息一下，我们继续调查。晚上九点钟的专案会，再碰头吧。” 案件过于复杂，所以我也没心思休息。整个下午，我都在电脑前面翻看着死者的衣着照片和尸检照片，脑子里则努力地想把这些奇怪的迹象给串联起来。 晚上六点，我抱着方便面正在吃的时候，看见一张卢华上衣衬衫的照片。我停下咀嚼，把照片逐渐放大，然后拍了一下桌子，说：“走！再去解剖室！” 卢华的尸体从冰柜中再次被我们拖了出来。 尸体因为冰冻的原因，更加僵硬，而且全身的皮肤都湿漉漉的。 “你们要看什么啊？”殡仪馆的工作人员有些不耐烦，说，“你们上午解剖完，下午死者家里人又来认尸，晚上你们又来解剖。这样一会儿冻、一会儿化冻，会加速腐败的。” 我笑了笑，没答话，拿起死者的右臂看了起来。 “看见了吗？”我说，“死者的右臂上，有一个椭圆形的皮下出血！” 陈诗羽的表情最为惊讶，说：“哎呀，中午尸检的时候没有看到这儿有皮下出血啊！怎么死了以后，还会有皮下出血啊？” “很好。”我微笑着说，“皮下出血是生活反应，死后不会再形成，小羽毛已经有了这方面的意识。” “那就奇怪了。”陈诗羽说，“尸检的时候，我明明看到你们检查过死者的关节的，绝对没有这一处皮下出血！难道是闹鬼了？” “瞎说什么啊？”林涛看看窗外逐渐降临的夜幕，说。 我说：“皮下出血这个东西很奇怪，如果程度较轻，在初次尸体检验的时候经常有发现不了的情况。尸体经过冷冻，皮肤失水变薄，通透性也就增加了，这时候浅淡的皮下出血就会出现在可视程度内了。” “原来冷冻也可以帮助尸检啊。”陈诗羽恍然大悟。 “这是咬痕啊。”赵永说。 我点点头，说：“我是看照片的时候，发现卢华的衬衫袖口有个很微小的撕裂痕迹，就想到了这一点。这是卢华穿着衣服被人咬了一口。” “齿列很特殊。”大宝说，“中切牙是歪的，右侧侧切牙缺失，尖牙非常尖。我们检验过两名死者的牙齿，这样的齿列，肯定不是卢华自己或者是牛青岚的齿列。” “这样的齿列，有一点好处。”我说，“特异性非常强，可以做出牙齿模型，来和嫌疑人的牙齿进行比对，这是个很好的证据。” “我这就把压痕固定下来，安排法医人类学专业的同事去做牙模。”赵永兴奋地说。 “这还提示了一个问题。”我说，“在案发现场，除了两名死者，还有第三个人存在，而这第三个人，很有可能就是凶手。” “可是牛青岚为什么裸体，卢华为什么被咬，为什么会摔死，还是一个谜啊。”林涛说。 我没有说话，因为我的脑子里思潮翻滚，我感觉到自己就快要找到问题的答案了。 在晚上九点钟准时开始的专案碰头会之前，答案已经逐渐清晰。 “怎么样？”年支队长在会议开始时说，“听说法医又去复检了尸体，有什么新的发现吗？” 赵永说：“有发现，我们发现卢华被人咬了一口，这个人在卢华尸体上留下的咬痕，可以制作成牙齿模型，作为证据使用。” “也就是说，你们确定这是一起命案了？”年支队长有些担忧。 我点点头，说：“中午开会的时候我就提出过几个疑点，结合这个属于第三人的咬痕来看，这无疑是一起命案。” “那我们下一步，应该往哪个方向开展侦查工作呢？”年支队长问。 我说：“且听我慢慢说来。首先，我们来分析一下踩踏痕迹为何和牛青岚脱衣服的地方相距三四百米。这说明两名死者在生前，应该是被人为地分开了。” “分开了？”年支队长说，“不是一个人所为？” “嗯。”我点点头，说，“我认为凶手至少有三个人。牛青岚为何会乖乖地脱衣服？而且是自行脱衣服。肯定不会是她觉得很热，而是因为有人命令她脱衣服。在没有发生肢体接触的情况下，就能让她乖乖脱衣服的，肯定是个持刀的凶手。” “她是一个十八岁的女孩子，而且是处女，就是有人持刀，在没有伤害到她之前，也不会乖乖就范吧？”年支队长说。 我点点头，说：“是的，女孩子都有害羞心理，脱得一丝不挂这种事，不是轻易可以做得出来的。除非威逼她的，也是个女性，而且这周围，只有她们两个女性。” 大家都在点头。 我说：“这也是为什么卢华被隔离到几百米之外的原因。” “那这个女凶手，为何要她脱衣服？”年支队长问。 我摇摇头，说：“牛青岚的牛仔裤口袋有被翻出来的痕迹，而且卢华的裤子口袋里有一些泥土，说明有人手上沾着泥土想去掏口袋。所以我也分析出，这应该是一起劫财案件。只是劫财并不成功，卢华身上的几十块钱都在。但是抢劫只需要掏口袋就行了，为什么还要死者脱衣服，这个我还是没能想清楚，破案后才会知道吧。” “你接着说。”年支队长说。 我说：“其次，我认为把卢华控制到几百米之外的人，应该有两个人。” "why?" “第一，卢华的颈部有威逼伤，说明有一个人有刀可以控制他。但是卢华手臂上又有一个咬痕。试想卢华和凶手发生了搏斗，凶手肯定会用刀来攻击他，但是为什么要用咬人这种下三滥的手段呢？只有一种解释。就是卢华挣脱了持刀歹徒的控制，在和另外一名没有持刀的歹徒进行搏斗的时候，被歹徒咬了一口。” “这两个持刀的歹徒会不会是一个人？”年支队长问。 我摇摇头，说：“对两个人的控制是同时的，所以应该是由两个人持刀。” 我喝了口水，接着说：“再次，从这个咬痕来看，我认为凶手应该年龄偏小。我也有依据。第一，既然有人持刀，居然还能让卢华挣脱控制，说明凶手的控制力很弱；第二，卢华长得瘦弱得很，和这样一个男孩子搏斗，还需要咬人的，肯定不会是个强壮的青年。” “有道理。”赵永说，“我们处置的伤害案件，咬人的一般都是妇女和孩子。像泰森那样的，确实是少数。” 我说：“最后，我总结一下，我认为两名死者是在五月二十日晚上，去案发现场赏花，在缠绵的时候，遇见了至少三名犯罪分子。凶手的目的很明确，就是劫财。分工也很明确，由一名女凶手控制牛青岚，由两名男凶手控制卢华。他们把两名死者分开数百米远，采用威逼的手段进行劫财。女凶手这边不知道出于什么原因，让死者脱光了衣服，在没有抢劫到钱财后，将其一刀杀死。两名男凶手对于卢华的控制突然失效，并没有成功劫财，卢华和其中一名发生了搏斗，然后在仓皇逃窜的时候，误入防空洞，在光线陡暗的情况下一脚踩空，从而摔死。凶手见状，一起沿大路离开现场。只有这样，才能全部解释现场的情况。” “有一些道理。”年支队长说，“也就是说，下一步，我们就重点查找至少一女两男的抢劫犯罪团伙？” “持刀抢劫，可能有犯罪前科。”我说，“而且凶手很年轻，如果再大胆点儿，可以推断至少两个男凶手都是未成年人。” 年支队长点点头。 我接着说：“还有一点，不是很确定，但是必须考虑。就是你们发现没有，整个抢劫、打斗过程中，凶手并没有踩踏花圃。就连卢华都在逃跑中踩踏了一大片花苗，可是并没有发现凶手刻意踩踏花苗的迹象。从这一点心理特征，我觉得凶手可能就是当地人，家里面可能就是种花的，所以他们有不踩踏花苗的潜意识。这不是说他们道德品质高尚，而是一种从小培养的潜意识。即便道德再败坏，这种潜意识还是可以发挥作用的。” 年支队长又点了点头。 我笑了笑，说：“能做的就这么多了。我们做出的牙齿模型，可以和你们排查出来的嫌疑人进行比对，作为摸排的依据。这个凶手的牙齿很特殊，比对起来并不困难。” 从专案组回到宾馆，疲惫的我一头扎在床上呼呼大睡了起来。 梦中，我看见一个白衣女子拿着一把手术刀，正在慢慢地向我靠近。 第二天，不知道是不是因为大家都太累了，当我醒来的时候，已经上午十点了，居然几个人都没有起床。我拿起床头柜上的手机，就看见年支队长发来的短信。短信是上午八点二十发来的，内容是：“案件已破，等你来局再向你汇报。” 我一蹦三尺高，叫上大家一起，赶到了汀棠市局年支队长的办公室。 此时年支队长正在自己办公室的小板床上睡觉，被我们叫醒后，睡眼惺忪地向我们介绍了破案的经过。 根据我们提供的推断，刑警们对案发现场周边乡镇和汀棠大学学生曾经报案未破的几起抢劫案件进行了分析研判。果真发现有一个犯罪团伙，由两男一女组成，经常在周边干些偷鸡摸狗的勾当，还抢劫学生。 专案组对周边乡镇所有种花的人家进行了调查，发现一个叫作李玉的二十岁无业女子有重大犯罪嫌疑。通过对李玉经常联络的人进行调查后，又发现了一名十七岁的无业辍学男子方林，他是李玉的男朋友。这个十七岁的男孩有个十三岁的弟弟方舒，几个人经常混在一起。 专案组决定从方舒入手调查。在方舒到达学校后，警方在学校老师在场的情况下，询问了方舒。方舒毕竟还是个孩子，看见几个警察后，腿都吓软了。 敏锐的侦查员观察了方舒的牙齿，中切牙是歪的，右侧侧切牙缺失，尖牙非常尖。在和牙模比对一致后，另两组侦查员立即对李玉和方林采取了抓捕行动。三个人在被带进刑警队后不到十分钟，就纷纷交代了自己的罪行。 五月二十日晚上，三个人因为没钱上网，决定去花圃附近抢劫。他们知道这里经常会有一些大学生来谈恋爱，他们每次抢劫，大学生们都会给他们一些钱，报案的也很少。即便报了案，因为有夜幕的掩护，警察也没那么容易破案。这一次，他们依旧像往常那样去花圃抢劫，看到了正在花圃边亲吻的牛青岚和卢华。虽然李玉他们拿着匕首，但是牛青岚和卢华都称自己没钱。此时卢华丢下牛青岚迅速逃窜，但是在几百米外被方林按倒。 李玉把牛青岚控制在路上，见方林重新控制了卢华，她稍缓了一口气。但是李玉怕牛青岚也会逃跑，所以要求牛青岚把衣服脱光。“反正那几个男人离那么远，这里就我们两个女人，你也不用害羞。”李玉这样半说服、半威逼地让牛青岚脱了衣服。这个要求的目的很明确：第一，牛青岚脱下来的衣服李玉可以进行仔细的搜查；第二，牛青岚脱光了衣服，自然就要考虑到逃跑的时候遇见别人是一件很羞耻的事情，所以会不好意思再逃跑。 在确认过牛青岚身上真的身无分文后，李玉控制着牛青岚向大路方向移动，目的在于让其远离衣物，彻底放弃逃跑的想法。 而卢华为了保住自己口袋里的几十块钱，依旧没有放弃抵抗。他在佯装掏钱的时候，一脚跺在方林的脚上，方林顿时失去了奔跑的能力，大喊着让方舒抓住卢华，不然他一定会跑去报警。此时卢华想继续逃跑，而十三岁的方舒则死死抱住卢华的大腿。卢华撕扯方舒的头发想摆脱控制，方舒就在卢华的胳膊上狠狠地咬了一口。 毕竟方舒只有十三岁，他最终没能在方林重新站起来之前控制住卢华，让卢华跑进了花圃。方林一瘸一拐地看着卢华跑进了防空洞，然后就听见了卢华的惨叫声和头部撞地的声音。 方林走到防空洞口，看见了月光照射下的台阶上有大片的血迹，顿时吓昏了头。脚上的疼痛也不记得了，带着方舒向李玉方向跑去，还高声叫着，那男的摔死了。 听到这一句，李玉也慌了神，牛青岚更是惊恐无比地叫了起来。李玉见牛青岚叫了起来，下意识地一刀捅了上去，哪知道这一刀居然直接插进了牛青岚的后背。刀子再拔出来的时候，牛青岚直接倒地不动了。 原来只想抢几十块钱上网，却闹出了两条人命。三个人都跑回家躲了一整天，见警方并没有找上门来，才放心。 所以五月二十二日一早，方舒又背起了书包去上学，却被警察拦在了学校里。 “所以说啊，谈恋爱的时候，别傻乎乎地往没人的地方跑。”大宝坐在我们返程的车上，说，“没人的地方说不准就是犯罪的地方哦。” 林涛点头，说：“本来还准备花前月下的，结果月下消魂了。” “我说你的语文是体育老师教的你还不信。”大宝笑着说，“知道销魂是什么意思吗？销魂是指因过度刺激而神思茫然，仿佛魂将离体。形容悲伤愁苦或性感极致。” “我说的是'消'魂，消灭的消，消失的消。”林涛辩解道。 我们回到省城的时候，已经是下午了，由陈诗羽提议，大家表决通过，翘班两小时，回家休息，等第二天再去上班。 结果翘班的报应来得很快，当天夜里两点钟，我放在床头柜上的手机就响
