Chapter 12 The Eleventh Case

The "Scavenger Project" had a fifth case a week earlier.This one is different from the previous ones. There is an eyewitness who witnessed the whole process of the murderer killing the victim. "The weather is hot, and everyone doesn't live here anymore. The main reason everyone lives here is that it used to be a small power station, and there are many houses that can keep out the wind and rain. But no matter how hot the weather is, how many mosquitoes there are He doesn't even want to leave because of the smell of the garbage dump next door. He regards this place as his own home." The little boy sat on the ground with his knees hugged, shivering, "There are too many mosquitoes here, so all of us Moved to the footbridge two miles away."

"How old are you?" Chen Shiyu asked softly. "Thirteen." "Don't you have to go to school?" "My parents are dead, and there is no one at home, so I have to follow my uncle to pick up trash in the city." The little boy glanced at Chen Shiyu in uniform, as if he was a little afraid. "You said you saw it, what did you see?" Chen Shiyu continued to ask. "Don't ask." I interrupted Chen Shiyu and said, "How many times has he been asked. Every time he is asked, he will be hurt. I think he should be helped by the government."

Chen Shiyu looked at me and swallowed the questioning words. "Don't worry, it's useless to worry." Lin Tao comforted, "This case has dragged on for so long. The main reason why the case hasn't been solved yet is that the murderer has planned carefully, and we haven't fully understood the murderer's motive." "Who's in a hurry? I'm not in a hurry." Chen Shiyu said, "This is the first case I've come into contact with since I started working. Don't I want to solve it earlier? Otherwise, let my classmates know, how embarrassing I am. !"

I smiled and waved them out of the room. "The boy is called Goudan. He, his uncle, and more than a dozen people in the village live by picking up waste in the city." I said to them while reading the records of the investigation department, "They usually live in this small area. But when summer comes, because the garbage dump near here has a strong rotten smell, they move to the nearby overpass. Only the deceased, Lao Hei, still lives in the small house. On the evening of July 15, Goudan obeyed himself Uncle’s order to pick up things from the small house they lived in before. Because it was already dark at that time, Goudan was a little scared. When he touched the house, Goudan wanted to call Old Hei to help him illuminate. But when he got to Old Hei When he was in the room, he seemed to hear a woman's voice."

"A woman's voice?" Everyone was listening to the story quietly, only Dabao would express his surprise from time to time. "What's so strange?" Lin Tao said, "Is it the first day you know that the suspect in the 'Scavenger' series of cases is a woman?" "Goudan said it sounded like a woman's voice, but I couldn't hear what he was saying." I continued, "Goudan has been with these scavengers for a long time, and these scavengers also talk about men and women in their spare time. So Goudan is also very curious about these things. So Goudan crawled under Lao Hei's window, trying to peep through the cracks in the dilapidated curtains."

I turned over a page of the file and continued: "What Goudan saw was that Lao Hei was lying naked on the ground, and a woman in white was riding on Lao He's body. It seemed that Lao He wanted to take off the dress of the woman in white. During the lifting process, you can see a woman in white wearing a pair of blue shoes, which is very strange." "Blue shoes?" Lin Tao touched his chin and said, "It should be a shoe cover on the outside of the shoes. If there is not enough light in the room, it may be mistaken for a pair of blue shoes." I nodded in agreement and said, "Suddenly, Lao Hei let out a muffled snort, and kicked his legs continuously. The woman in white just sat on Lao Hei like that, without moving. After a while, Lao Hei's legs stopped moving." The woman in white stood up at this time and turned around."

I looked up and looked around for a week.Dabao stared at me, expecting me to speak quickly; Lin Tao looked fearful; Xiaoyu lowered his eyelashes, as cold as ever. "According to Goudan, that woman is not alone, but a ghost." I continued. "Let me just say, if it was done by a human, we would have caught it long ago." Lin Tao's lips were trembling, "Only if a ghost did it, we can't catch it, otherwise how could there be no trace left behind?" ?” "Hey, you're a policeman! You're not a master!" Dabao patted Lin Tao on the shoulder and said, "The reason for not leaving any traces is because the murderer is deliberately erasing them, not because she has any superpowers, okay? Be materialistic, OK?"

"I think Goudan was in extreme fear at the time, so he might have mentally exaggerated some of what he saw." I said, "He said, this woman in white has no face, with long black hair hanging down. come down." "It's easy to explain. The hair is so long, and when it is draped forward, it basically covers the face." Seeing Lin Tao trembling, Dabao said with disdain, "If there is really no long face, that old black would dare to think about it." Have fun with her?" I nodded and said: "Goudan said that the white clothes on this woman's chest are covered with blood. After this woman killed someone, she fiddled with the corpse for a long time. Goudan really squatted outside the window." I couldn't help it, so I wanted to run away quietly, and then called the police. Unexpectedly, I accidentally kicked over a tile next to it. The woman turned around suddenly, and rushed out of the house with very agile skills. Goudan ran away, He ran near the rubbish dump before throwing off the woman in white who had been chasing after him. He hid in the rubbish dump and didn’t dare to come out. He didn’t run out until after dawn, found a large group of scavengers, and called the police.”

"You said, what the dog said, that woman didn't know what she was doing next to the corpse." Lin Tao hid behind Chen Shiyu, and said, "Could it be-eating corpses?" "Did you make a mistake?" Dabao laughed, "She's writing the word 'scavenger' with honey, okay?" "Back then, Han Xinmi wrote 'the overlord slays himself in Wujiang' by the river, tricking Xiang Yu into obeying the 'will of God' and slaying himself in Wujiang." I said, "Now this woman has used this method to complete her murder. Sign. Although I didn’t finish writing the word ‘husband’ because I heard the voice outside the window, I wrote these three characters on the spot, and it was still done by one person.” I said.

"What is the murderer's purpose for marking in this way?" Lin Tao asked. "Two possibilities. First, it's a provocation to the police. Second, it may be that she herself noticed the handwriting problem and didn't want to expose it too much, so she used ants to form the characters. Although she wrote on the ground with honey, but Ants didn’t make the word combination so perfect. At first glance, it seems that the three characters “scavenger” can be seen, but if you look closely at the details of each word, you can’t see clearly. Even the typo we identified before , it is not fully shown here. The murderer may have thought of this and used ants to form the outline of the characters, but we cannot see the details of the characters."

"But she has already left handwriting in the previous four cases!" Dabao asked. I shook my head and said, "Maybe it was a fluke. Maybe she discovered her typo and wanted to continue to mark herself in the next case, so she used this vague way to prevent us from doing it later. This clue was found in the case." "Indeed." Lin Tao said, "This is probably the only clue that can identify the murderer." "Even though we have found this clue, we still haven't found the murderer." Dabao said dejectedly. "Uncle, can I go home?" We were so engrossed in the conversation that Goudan was already standing behind us. "Last question." I asked, "Can you recall carefully the appearance of the woman in white?" "She has no face!" A terrified expression appeared on Goudan's face. "What about the figure? Fat? Thin? Can you describe it?" I asked. Goudan raised his head, looked at us, pointed at Chen Shiyu and said, "It's similar to this sister." We looked at Chen Shiyu together. Chen Shiyu panicked and said, "Huh? Me? I was shot while lying down." In the special case team, the new murder case made every special case policeman frown. The "Scavenger Project" was led by the criminal police detachment of the provincial capital. The criminal police officers in charge of the case from the Yuntai City and Senyuan City Public Security Bureau also made a special trip to the provincial capital to participate in the special case meeting. "This series of special cases has been issued five times." Deputy Director Zhao Qiguo said, "Although the dead are scavengers or mentally disabled patients, they are still alive! If the case is not solved, there is no way to explain it to the people! But we What? It’s been four months! It’s been four months! No valuable clues have been found yet? Can this still be said that we are an excellent collective? Is it an invincible collective?” Everyone bowed their heads in silence. "I don't want to talk nonsense anymore. I hope everyone cheers up." Chief Zhao said, "The dozens of brothers here, starting today, put down all their work, stop their vacations, and try their best to solve this case. Starting today, There are no holidays, no weekends, until the case is solved! With regard to the case released today, the technical department will report the specific situation first." The venue was silent for a while, and Xie Ming, chief of the trace inspection department of the Provincial Urban Bureau, said: "After the on-site inspection work was completed, except for the word 'scavenger' that appeared on the ground near the corpse and was poured out of honey, there was no evidence of any trace. Clues of value." Chief Hu went on to say: "After the forensic examination of the corpse, no valuable clues were found. The murderer's method of committing the crime is exactly the same as that of the four previous cases. He used a scalpel or other relatively thin props to stab the heart with one knife. , resulting in death from hemorrhagic shock. The time of death was around 11:30 last night, which is consistent with the time described by eyewitnesses." "Wearing gloves and shoe covers to commit crimes again?" I asked. Xie Ming nodded and said: "You can see the usual imprints of shoe covers at the scene, without any shoe sole pattern. Because the murderer didn't stay at the scene for a long time, there is no evidence that she wore gloves, but she didn't leave any fingerprints at the scene either. .” "The investigative department reports on the progress." Director Zhao said. "After investigating around the scene, it was found that there was no surveillance video around the scene." The investigator said, "There was no second witness who spotted the woman in white." "Have you expanded the search area around the scene?" I said, "The murderer has bloody clothes and shoe covers. If he leaves the scene, he must discard these things, right?" "It can be cleaned or burned." The investigator said, "In short, there are no obvious suspicious items nearby. You know, there is such a large garbage dump nearby, and it is impossible to search it carefully." "That is to say, the fifth case in the series has happened, and we still have no clue?" Director Zhao asked with his eyes wide open. Everyone bowed their heads in silence. "Is there still no progress in the previous mopai?" I asked. Chief Hu nodded and said: "At that time we analyzed the accommodation records of Longfan, Yuntai, and Senyuan at the time of the incident, and there were quite a few people who met the requirements. For women, they may be engaged in legal, medical, or other fields. The personnel with previous convictions checked one by one, and they all felt that they were not very similar. Because there is no basis for screening, there is no way to confirm or rule it out." "Now let's talk freely, I want to work on the next step." Director Zhao said. I cleared my throat and said: "I think the next step of the work needs to be carried out around three aspects. First, continue to investigate the personnel within the range mentioned by Section Chief Hu. The black hotels in the three cities that do not carry out identity registration We also need to ask and investigate one by one to prevent any omissions. If the murderer deliberately goes to other places to commit crimes, he will not go to a regular hotel to register with a real ID card. Except for those who have no time to commit crimes, everyone else must undergo handwriting identification. Although the murderer now It is very likely that you will find your habitual typo, and you may camouflage it when you are under review, but we can’t give up on this path. Second, conduct a blanket inspection of the surrounding surveillance video, and all the white clothes that appear in the surveillance video , long-haired women must be identified, and strive to find out who these women appear around at a specific time. Third, I think it is possible to carry out a round of investigations on the prostitutes who have been 'introduced'. " "Are you suspecting that a prostitute committed the crime?" Director Zhao asked. I said: "Using hue to make opponents stronger than me relax their vigilance, this first reminds me of a woman in the dust. Since I don't have the slightest grasp, it's better to treat a dead horse as a living horse doctor and try my luck." "That is to say, you are now starting to question the condition of 'involving law and medicine'?" Director Zhao said. I nodded and said: "Since the investigation is invalid, we must consider that the scope is not set correctly." "Then, where should we start now?" Director Zhao asked. I shook my head and said, "I don't know either. A woman with long hair like Chen Shiyu is nothing more than that." "Not even age." Director Zhao said, "In the three cities, there are millions of women who meet this condition, looking for a needle in a haystack." "In addition, I need copies of the materials of all five cases." I said, "After we go back, we will also study carefully to see if we can find any new discoveries." This week passed very quickly. I, Dabao, Lin Tao, Chen Shiyu, and even Han Liang spent every day in the office carefully reading the files of the five cases, trying to find out what we had missed. The dossier is very detailed, but there is nothing chewy. The murderer's methods are so clever that we can't insert needles seamlessly. "Is there really a perfect crime?" Dabao slowly began to doubt the idea he had always believed in. At the same time, the investigation work launched by the task force is also in full swing, but to no avail. On the morning of July 24th, while we were continuing to review the files, Master called: "The Public Security Bureau of Liqiao City just sent an invitation letter, asking us to send trace inspection and forensic experts to Liqiao for support as soon as possible." "Liqiao?" I said, "there aren't many murders there, but there are quite a lot of letters and visits. Could it be another letter and visit case?" We are sprinting on the "scavenger project", and I am usually keen to go out to the survey site, but I am a little slack at this time. "No, this is a homicide case." Master said, "A young woman was killed in her home. According to the preliminary investigation results, the murderer cleaned up the scene." I nodded silently. Although the backlog of cases needs to be cleared as soon as possible, the discovered cases must be resolved as soon as possible, and no debts will be owed. I hung up the phone, looked around at my colleagues in the office, and said, "Liqiao murder case, let's go immediately." Everyone stood up to prepare things, only Dabao was still sitting in his seat, flipping through the file and wringing his fingers like he was trying to figure something out. "Hey, at the scene of the murder case, hemorrhoids will develop if you don't go there." Han Liang laughed. I raised my hand, and asked Dabao in a tone of asking for opinions, and said, "How about this, let's go to the scene in Liqiao, let Dabao stay and continue to read the files, and if necessary, organize the city bureau forensic doctor to re-examine the body. How about it?" Dabao nodded.The few of us were very surprised. How could this forensic doctor, who usually couldn't sleep without going out of the scene, leave a murder case uncovered and was willing to stay at home and chew on that difficult bone? "I think Dabao and Mrs. Bao have just stabilized, so they want to reduce business trips?" Lin Tao asked while sitting in the car. I shook my head and said, "Looking at Mrs. Bao's character, the breakup with Dabao was not because she didn't support his work, but because she felt that Dabao didn't care about her. How virtuous Mrs. Bao is, she won't stop Dabao from going on business." "If Dabao doesn't go on business trips anymore, then the allusion of 'going to the survey site and not getting hemorrhoids' will no longer exist." Han Liang laughed. I lowered my head and thought for a while, and said, "I always feel that Dabao seems to have discovered something, but he may not be ready to tell us." "No matter what, let's clear up the current murder case." Chen Shiyu in the passenger seat said coldly. At the request of the Liqiao City Public Security Bureau, our police car drove into the old town of Liqiao City, where the buildings were all protected as original ancient dwellings, and there were small alleys with twists and turns.The police car stopped at the entrance of an alley, because forensic doctor Wu Xiang from Liqiao Public Security Bureau was waiting for us at the entrance of the alley. "I hate these alleys the most." Lin Tao jumped out of the car and said, "It's quite scary." Chen Shiyu covered his mouth and smiled, and said, "You are the most timid policeman I have ever met." Lin Tao stiffened his neck and said, "I'm timid? I've seen all kinds of corpses, okay? Besides the forensic doctor, does anyone else dare to say that I'm braver than me? I'm just a little afraid of ghosts." Under the guidance of Wu Xiang, we walked through the maze-like alleys and came to one of the smaller gates. The alley at the entrance was cut off by two parallel warning belts, and more than a dozen police officers squeezed on both sides of the warning belt, asking residents who lived nearby and needed to cross the alley to detour. "I hate this alley, and there are other reasons." Lin Tao tried to save some face, adding, "In such a narrow alley, the traces of the door are almost gone." "The scene is here." Wu Xiang said, "As Section Chief Lin said, when we arrived, we surveyed the ground of the alley at the entrance. Unfortunately, there are too many fresh traces, and it is impossible to distinguish which ones are related to the crime. .” I turned my head to look around and said, "Since there are no traces at the door, why don't you pull the warning belt around the door, this will seriously affect the travel and life of the surrounding residents." "No." Wu Xiang shook his head and said, "There are some ancient buildings around here, usually a family with a small courtyard. But the scene is not. The door of the scene is a suite, and you can directly see the scene from the door. The situation. Historically, this was a punishment room for a rich family. It was a small independent room built by a big family at the back of its own courtyard. Employers who made mistakes would face the wall and think about their mistakes here. Later, when they were liberated, This piece of house is divided into several independent small courtyards and distributed to the common people. This one and the small courtyard next door belong to the same landlord. The landlord lives in Longpan City and comes back once a year to collect rent.” "Who are these two rooms rented to?" I turned my head and looked at a middle-aged couple who were being questioned by the police at the door next door. "The one next door is a supper shop." Wu Xiang said, "A family of four, a husband and wife and two children. It is said that at eleven o'clock last night, the whole family went to the side of the pedestrian street in the city to set up supper. They didn’t come back to sleep until after six o’clock in the morning. When we found their house, they were indeed sleeping.” "I've heard of this, Liqiao's supper is also famous in the whole province." Lin Tao said, licking his lips. "What about the deceased?" I said, "The conditions for renting such a small house should be very poor, right?" I looked at the closed door at the scene and asked. Wu Xiang shook his head and said: "According to the verification of the deceased's identity, the deceased is a girl from the countryside around Liqiao. She arrived in Liqiao two years ago and has been renting here. The girl's name is Yang Yan, 24 years old, unmarried .According to the Lu family next door, the girl is very introverted. She has been a neighbor for two years without saying a word. The girl goes out in the morning and comes back in the afternoon. She doesn’t know what kind of work she is doing. Sometimes, men will come over at night.” "A man? A prostitute?" Lin Tao asked. Wu Xiang shook his head and said, "I'm not sure about this. The Lu family next door can't tell. They have seen it a few times, and they don't care whether it is a man or not. But judging from the girl's usual behavior and attire, it is very Pure, not like a prostitute." "At present, we are organizing forces to investigate Yang Yan's means of earning a living." An investigator said. I put on my survey equipment, opened the door and walked into the house.Contrary to what it looks like from the outside, the room is warmly decorated and cool. I looked up at the air conditioner on the wall and said, "The air conditioner on site cannot be turned on randomly!" Wu Xiang nodded, his voice weakened from behind the mask, and said, "When we came in, the lights, air conditioner, and TV were all on, and the computer was on the screen saver." The house is a suite structure.After entering through the gate, there is a narrow corridor. On one side of the corridor is the bathroom. The door of the bathroom is a simple stove with some pots and pans.At the end of the narrow corridor is a room with a large bed, a bedside table, a writing desk and a TV cabinet.Small but complete.Cartoon dolls are hung everywhere in the room, and the bed sheets are also pink, which makes people feel very warm. The wall facing the corridor and the gate is a whole pink curtain with a picture frame hanging on it.The girl in the photo frame is wearing a school uniform, smiling silly at the camera.Although the girl's dress in the photo is outdated, she can't hide her beautiful face and charming smile. The girl in the photo is now completely naked, lying next to the TV cabinet. "There are a lot of mopping marks on the ground." Wu Xiang said, "Occult blood tests were all positive. We followed the direction of the mopping marks and found the mop in the bathroom, which also had blood on it." "Is the deceased bleeding?" I looked at the naked female body lying under the TV cabinet. "Yes." Wu Xiang said, "I took a preliminary look just now, and it should be a ruptured jugular vein." "Then the scene is really clean." I squatted on the ground and looked at the ground.If you don't look carefully, there is no trace of heavy bleeding on the floor at all.Now that even the bloodstains have been completely cleaned up, it is even more impossible to find any footprints on the ground at the scene. "Is there any sign of shaking at the scene?" Lin Tao asked. Wu Xiang shook his head and said, "This is a scene of sexual assault, and there is no sign of financial infringement." "Sexual assault?" I frowned and asked, "Do you have any judgment on the time of death?" "The air conditioner is turned on in the room, and the set temperature is 26 degrees Celsius." Wu Xiang said, "Considering that the temperature of the air conditioner is not constant, and the corpse is located directly under the air outlet of the air conditioner, we think that the temperature of the corpse dropped faster than usual. Combined Rigidity and corneal cloudiness, our preliminary analysis shows that the deceased died after twelve o'clock last night." "So, after midnight?" I asked. Wu Xiang nodded and said, "At this time, the Lu family next door is not at home. The nearest neighbor is tens of meters away, so the nearby residents did not hear the sound of fighting or calling for help." "Then how did the murderer enter the scene?" I walked to the window on the opposite side of the gate, opened the thick pink curtains, and saw that the window was closed tightly, and the metal guardrail outside the window was intact. "From the investigation, the deceased was introverted and didn't socialize with others." Wu Xiang said, "There were no signs of prying or damage on the window side. Therefore, the murderer's entrance and exit should be the gate." "I've seen it. The outside of the gate is an ordinary wooden door, but there is a thickened anti-theft door on the inside." Lin Tao looked at the keyhole of the anti-theft door and said, "The gate has no signs of prying or damage. Outside The wooden door is also in normal condition." "Who reported it? What was the scene like when you first arrived?" I asked. Wu Xiang said: "A middle-aged man named Bao Linao who lived about 100 meters away from the scene reported the crime. He said that at seven o'clock this morning, he passed the alley and found the door was wide open. You can see the female corpse under the TV cabinet in the room at the door. So I reported it. When the police station arrived at the scene, the reporter was the only one who looked inside." "It's past seven o'clock, and no one has passed by here yet?" I looked outside the gate. "Residents in the south live a more comfortable life." Wu Xiang smiled and said, "Go to work at nine o'clock, and our streets are not blocked at eight o'clock. At seven o'clock, that is very early. Moreover, this place It is relatively remote, and generally only people who live nearby will pass by. The alleys are intricate, and even if you live nearby, you may not pass through this small alley." "How did the murderer get into the scene?" I asked this question again. "Without a doubt, enter peacefully." Wu Xiang said. "An introverted girl who randomly lets people into her boudoir at midnight?" I asked. "And it's a man." Wu Xiang didn't answer my question, but added, "In the vagina of the deceased, the sperm spot test was positive." "Tell me, could it be the man the Lu couple saw?" I asked. "You mean, an acquaintance?" Wu Xiang said, "I feel relieved when you say that. We also thought it was a typical homicide committed by an acquaintance. After all, a woman who lives alone opens the door in the middle of the night, and most people want to cheat It can’t be cheated either.” I walked around the room, the scene is very small, and there is nothing special to investigate.I walked to the pink bed sheet, and saw that the bed sheet was still neat, with a thin quilt piled on top of the bed sheet, and the quilt cover was also matching pink. "Is it popular among young people to turn on the air conditioner and cover up the quilt?" Wu Xiang said old-fashionedly. I dragged the quilt to a corner of the bed, and saw that the sheets were clean, and of course, neat. "The rape didn't happen in bed?" I asked. Wu Xiang shook his head and said: "We have carefully checked the quilt and sheets, and they seem to have been laid carefully. We analyzed that the deceased should have been sexually assaulted near the TV cabinet, because her pajamas were scattered around there. There were bloodstains on the body. The bloodstains were not much, and it was in the shape of splashes. The analysis should be that the pajamas were taken off and thrown nearby, and the deceased was stabbed in the neck with a knife. Unfortunately, the vicinity of the corpse has been cleaned, and there is no trace." "That is to say, whether it is sexual assault or murder, these actions are kept away from the bed?" I asked. Wu Xiang nodded. "Then, why is there blood on it?" I lifted the thin quilt and saw that one side of the quilt was stained red with blood. "Yo, I really didn't notice this." Wu Xiang said, "The original location of the quilt was on the bed, and the bed was clean, so we didn't look carefully. Come on, quickly pick up the quilt." "It doesn't matter. The acquaintance committed the crime, and the DNA was left at the scene. I don't think this case is difficult to solve?" I smiled and said, "The investigation has already started, and the DNA is also working overtime. It is estimated that the result will be available in three to five hours." We've got to hurry up and do the autopsy, and try to get it done before their work is done." Wu Xiang and I worked together to lift the corpse to the dissecting table. When the corpse was turned over like this, we could see that there were injuries everywhere on the corpse. "Hey, when I was at the scene, I only saw that the back of the deceased was intact." Wu Xiang said, "Looking at it this way, the whole body is full of injuries." The injuries of the deceased were spread all over the body in many places, mainly subcutaneous bleeding and abrasions.It can be seen from this that the deceased had undergone a violent struggle during his lifetime.We measured, photographed and recorded the injuries one by one, and it took more than an hour for the autopsy alone. "The abrasions on the deceased's body were mainly caused by scraping against furniture during the fight. As for the subcutaneous bleeding, we can see that except for some bumps, the others are concentrated in the limbs. This is a typical restraint injury." I said. "I've listened to your lectures before, and you think that the restraint injuries are numerous and obvious, which may indicate that the murderer's restraint ability is not strong, and he is evenly matched with the deceased, right?" Wu Xiang asked. I nodded silently and wiped the dead man's neck clean with a cotton ball.As the blood stains on the neck were slowly cleaned up, the skin on the neck was gradually exposed.In addition to an open wound on the right side of the neck, there were many skin abrasions on the front of the neck. I opened the eyelids of the deceased and saw many bleeding spots in the eyelids. I said: "The deceased showed signs of suffocation. You can see that the bleeding spots are obvious. This shows two problems. First, combined with the neck injury, the murderer's The deceased had a process of strangling the neck, which resulted in the death of the deceased by mechanical suffocation." "Ah? Didn't he die from blood loss?" Lin Tao said. "The deceased's body spots are pale, and the eyelids and nail beds are pale. It looks like a blood loss." I said, "It means that the deceased still had vital signs before the blood vessels were cut. This action of strangling the neck only caused the deceased to suffocate." Symptoms, at most, are coma." "What about the second question?" Wu Xiang asked. I said: "Secondly, the murderer's choking of the deceased did not lead to the death of the deceased. It also shows that the murderer's physical fitness is not very strong, and his control is limited." "These scratches on the neck can also explain this problem." Wu Xiang said. The abrasions on the neck of the deceased were distributed in a very messy manner, and the parts with obvious abrasions were mainly located on the left side of the neck.The abrasions on the left side of the neck were flaky, while the right side had multiple half-moon abrasions, apparently fingernail marks. "Look, what is the shiny thing on the stomach of the deceased?" Lin Tao said. I looked at the skin of the deceased's abdomen, but found nothing abnormal.So, I went to Lin Tao's angle to look, and I could see a small shiny area.Lin Tao stood relatively back, so when he looked towards the corpse, it was equivalent to shooting a side light, and he could see some positions where the light reflection and skin differences were small. I touched the shiny area with a cotton swab, and took out the test strips for the seminal spot test. After testing, it was indeed a seminal speckle. "However, the sperm spot has already been extracted from the vagina of the deceased, so is there any point in extracting it again?" Wu Xiang said. I said, "After all, they are two relatively independent sperm spots, so I think it will be safe to remove them. What if there is such a contingency?" The deceased's perineum had no obvious trauma, and the hymen was ruptured old. I took the knife and dissected the dead man's neck.The neck muscles of the deceased were bleeding extensively, and the right sternocleidomastoid muscle had been ruptured. Based on the skin, there were no trial incisions or scratches. A needle piercing a blood vessel. "The deceased and the murderer have traces of such a large-scale struggle, but the knife exists in isolation and is formed in a fixed position. This can restore the killing action." I said, "The murderer first strangled, let The deceased fainted, and then the jugular vein of the deceased was punctured with a knife." "Reinforcement behavior?" Wu Xiang asked. I nod. Wu Xiang said, "This murderer is quite sophisticated." "Indeed, strengthen the death of the deceased and clean up the scene." I said, "On the one hand, this shows that the murderer and the deceased are probably acquaintances. On the other hand, it shows that the murderer has a strong sense of anti-investigation, and it is very likely that he has a bad record." After autopsy, the deceased's organs all over his body were anemic, and the blood vessels were relatively empty. These are typical appearances of blood loss.Through the examination of stomach contents, it was verified that the deceased died at midnight on the 23rd. "I have some questions now." I said, "Why don't we go to the scene first and then meet with the task force?" Lin Tao was a little surprised, and said: "The scene has been mopped repeatedly, and most of the blood on the ground has been wiped clean." "Judging from the amount of blood lost from the corpse, there should indeed be a lot of blood at the scene." Wu Xiang said, "There are about 4,000 milliliters of blood in the human body, and I think at least 1,000 milliliters flowed to the scene. But there was no obvious blood at the scene. , even if we detected blood stains through the occult blood test, it is still a small amount. This shows that the murderer cleaned up so much blood after careful cleaning and mopping the floor many times." "What a thoughtful murderer." Chen Shiyu said. I shook my head and said, "Maybe it's thoughtful, or maybe it's just copying." "What is copying?" Chen Shiyu asked. I shook my head and said, "I'm not sure yet, let's go to the scene to see." Back to the scene again.Because the body has been transported away, in order to facilitate the entry and exit of nearby residents, the alert area has been reduced to the gate of the scene.A loose security tape surrounded the gate, and two policemen moved stools to sit at the gate. After I stepped forward and showed the site investigation certificate, I set off the security tape and walked into the scene. "There was no blood at all, right?" I asked Wu Xiang. Wu Xiang nodded. I said: "The neck of the deceased had a cut, so there would be a lot of blood pooled around the neck. And there should be a lot of splattered blood on the TV cabinet near the neck of the deceased. But we saw it at the scene. There are no blood pools or splatters, what does it mean?" Wu Xiang said: "First, the murderer should have moved the body so that the ground could be mopped clean without any dead ends. Second, the murderer not only mopped the floor, but also wiped the splattered blood stains on the TV cabinet." "Very good." I gave a thumbs up, and then asked, "Then what two problems can these two problems reflect?" Wu Xiang didn't understand what I meant and shook his head blankly. I said: "First, the corpse. If the corpse is moved, the semen spots on the lower belly in the original position are actually meaningful. It is possible that the murderer ejaculated on the belly of the deceased, and then because To mop the floor, so turn the body over." "Yes." Wu Xiang said, "At first I thought the deceased was lying prone, and the sperm spots on the belly were meaningless." 我接着说：“第二，我们知道打扫现场，主要是清理凶手留下来的痕迹，而不是清理血迹。凶手拖地的行为是在消除痕迹，但是擦桌子这个行为我就不能理解了。电视柜里也没有什么东西，按理说凶手不应该触摸，更没有必要去清理上面的喷溅状血迹了。” 吴响低头思索。 我继续说：“而且，现场留下了精斑，这是比指纹、足迹更有证明意义的痕迹物证，可是凶手肆无忌惮地把它留在了现场，没有做任何掩饰。你不觉得凶手的这个低级错误和他精心打扫现场这一行为是非常不吻合的吗？” “您是想说什么呢？”陈诗羽等不及了，问道。 我微微笑了一下，并没有作答，径直走到床边，把薄被铺开，对薄被一边的浸染血迹进行了仔细的观察，并用手摸了摸，发现血迹已经彻底干透了。 我更换了手套，把薄被放到桌上，对粉红色的床单进行了仔细的观察。床单上很干净，没有灰尘、没有毛发、没有血迹。 我直起身来，环视四周的环境，最后目光定格在办公桌上的电脑上。 “电脑，你们动过吗？”我问。 吴响摇摇头，说：“我们有一个勘查员看了，就是一个简单的桌面状态，没有打开什么程序。” “那看电脑之前，有对鼠标、键盘进行痕迹检验吗？”我问。 吴响摇了摇头，说：“好像没有。” 说话间，林涛已经拎起多波段光源，开始对鼠标和键盘进行检验。我在一旁静静地等着。 吴响说：“这个没有多大意义吧？你看，凶手进来强奸、杀人，然后又花费了那么大心思去打扫现场，他哪还有时间去上网？” 我没有搭话。不一会儿，林涛抬起头来，一脸沮丧，说：“可以看到是有新鲜指纹的，不过已经被纱布手套抹去了特征点，已无鉴定价值。” “那指纹也应该是死者的吧？”吴响说，“纱布手套？是我们勘查员做的吗？” “是。”林涛说，“很有可能是我们勘查员把指纹抹掉了，但是指纹究竟是死者的，还是凶手的，现在不得而知了。” 我皱着眉头思考着，不一会儿，眼前一亮，说：“快，主机电源按钮，指纹检验。” “不是，我有个疑问。”吴响说，“你们这样急巴巴地找指纹是什么意思？” “没什么意思，竭尽一切寻找证据。”我说。 吴响说：“现场有精斑啊！还有什么比精斑的证明力更好的吗？” “有的时候不好说。”我说，“比如，死者若是卖淫女，那么精斑还有什么价值吗？” “可是，为什么你们就对这台电脑感兴趣呢？”吴响问。 我说：“我开始就觉得奇怪，为什么现场会是电脑和电视同时开着？” “现在的年轻人，一边看电视一边玩电脑很正常啊？”吴响说。 我说：“如果真是这样，那么她完全可以把办公桌转一个方向，更方便。但是这个现场，若坐在办公桌旁玩电脑，则是背对着电视，这样不累吗？而且，午夜时分，说是看电视的时候睡着了，没关电视可以解释，但是电脑和电视都不关，都在使用，可就不好解释了。尤其是刚才你说电脑没有打开任何程序，那么她为什么不关电脑，而让电脑处于屏保状态？这不正常，是一个疑点。” “你的意思是说，电脑其实是凶手打开的？”吴响说，“使用完电脑后，凶手又把所有的程序都关掉了？这个凶手杀完人还这么悠闲自得？” “提取到一枚食指指纹。”林涛直起身来，说，“死者指纹我已经仔细研究过了，目前看，这枚食指指纹不是死者的。” “干得漂亮。”我笑了笑，转头对吴响说，“其实，凶手并不是悠闲自得。不如这样，我们两个来打一个赌。” “打什么赌？”陈诗羽插话道。 我说：“我赌，电脑里浏览器的浏览记录并没有被删除，而最近被关掉的网页，应该是搜索毁尸灭迹的办法。” 吴响满脸狐疑地晃动鼠标，打开了浏览器的浏览记录。 “如何清理血迹？”“杀完人后应该做些什么？”…… “真是神了。”吴响叫了一声，说，“你是怎么知道的？难道就是仅仅凭电视、电脑同时开启这一点？” “当然不止这些。”我说，“最重要的疑点，还得从尸体检验说起。” “最初的疑点，是从尸体上产生的。”我坐在专案组宽大的会议桌旁，说，“尸体的损伤分布非常广，说明凶手的控制力很弱。那么我们就要考虑老人、未成年人和女人。从作案动机看，既然是性侵害，就可以排除是女人作案。那么，凶手究竟是老人还是未成年人？午夜时分，死者会让一个老年男人进入现场吗？” “不排除会。”强局长说，“经过前期调查，死者是个暗娼。” “暗娼？”我有些意外。窗帘上挂着的那张纯洁的照片，实在难以和“暗娼”这个刺耳的词汇结合在一起。 “死者杨燕生前在一家所谓的'模特儿公司'上班，其职责，就是卖淫。”强局长说，“杨燕是农村人，从小丧父，母亲独自把她养大。但是两年前，母亲得了风湿性心脏病，生命垂危。为了赚钱给母亲治病，杨燕被人骗进了一个卖淫团伙，进行卖淫活动。因为面容姣好，杨燕很快就成了公司的'头牌'。不过，这个杨燕性格内向、要强，她只对一些固定的嫖客卖淫，生人一概不接待，收费很高。” “这些顾客里有老头儿？”我问。 强局长翻了翻笔记本，说：“目前调查的这些人中间，没有。不过，不排除我们的调查有遗漏的地方。” “我觉得调查正好把嫌疑人遗漏，太过巧合。”我说，“既然侦查员掌握了全部固定嫖客的名单，我们就应该充分相信。” 侦查员点头认可。 我接着说：“很快，在现场复勘工作中，我的疑点得到了印证。凶手在清理现场的时候，不仅仅清理了他可能留下的痕迹，就连一些喷溅状的血迹都清理得干干净净。这不是有反侦查能力的人所做的事情，而更像是不谙世事的未成年人效仿犯罪行为而做出的动作。” “这也是猜测吧？”强局长说。 我微微一笑，示意强局长少安毋躁，说：“在这个时候，我想到初次勘查现场的时候并没有解决的问题，就是被子上的血迹问题。被子在床上，而杀人的初始位置应该在电视柜旁边，那么被子上怎么会有浸染状的血迹形态呢？” “移尸？” “不。”我说，“床单没有打皱，床上不会是第一现场。既然不是尸体被从床上移下来，就应该是被子从尸体上移动到了床上。” “你是说，之前打斗的时候死者一直披着被子？或者被子在地上？”强局长说。 我摇摇头，说：“死者身上有很多擦蹭损伤，不会是披着被子。被子上没有喷溅状血迹，说明被子开始也不在地上。所以，我认为凶手在把死者的颈动脉割破后，用被子掩盖了尸体。” “掩盖尸体？”强局长皱起眉头，说，“那他为什么还要把被子重新给拿回床上？” “对，这就是问题的核心所在。”我说，“凶手在杀完人后，用被子掩盖尸体，在离开之前，又把被子重新放回床上。同时，不知道大家有没有注意到现场的床单。” 说完，我在幻灯机上打开了一张现场床单的照片。 “很干净。”强局长说。 我点点头，说：“被子上是有血的，但是这些血却没有被沾染到床单上，这是为什么？” “对啊！我怎么没有想到？”吴响插话道。 我说：“只有一种可能，就是被子被重新放回床上的时候，血迹已经干了。” “干了？那么多血，干了的话至少也得一个小时吧？”吴响说。 我点点头，说：“差不多。现在问题来了，在这一个多小时中，凶手在做什么？” “打扫现场。”吴响说。 我摇摇头，说：“不。现场是用水冲洗地板，然后拖擦的。但是被子上并没有污水的痕迹，也没有血液被水冲淡后浸染的痕迹。说明凶手在打扫现场的时候，被子已经重新回到了床上。” “那凶手在做什么？”强局长问。 我说：“开始我也想不通，后来到了现场，看到了电视、电脑，想起之前说过，现场的电脑和电视是同时开启的状态。根据这一疑点，我认为凶手很有可能是在上网。上网做什么呢？寻找毁尸灭迹的办法！” “强奸、杀人、掩盖尸体、上网寻找灭迹办法、把被子掀开、打扫现场。”强局长说，“你还原的这个现场过程，我很认可。可是为什么他要在打扫现场的时候把被子重新拿开呢？” “很简单。”我说，“被子铺在地上会掩盖部分血迹，挡事儿了。” “那么，你还原出的这个过程，又能说明什么呢？”吴响问。 我说：“这个过程的关键点是上网寻找灭迹方法，然后照搬照抄地施行，以至于形成了拭去现场血迹这个没有意义的动作。这个行为，说明凶手在杀人后，不知道该怎么办，说明他没有反侦查能力，而且心智并不是非常成熟。这说明凶手应该是一个未成年人！” “未成年人？”吴响问，“可是未成年人怎么会强奸呢？怎么会和平进入现场呢？” “这样看，我们抓错人了？”强局长幽幽地来了一句。 “你们都抓人了？”我问。 强局长点点头，说：“DNA实验室检出死者阴道内的精斑后，就上网进行了比对。很快，这个精斑和一个曾经受过打击处理的人比对同一。而这个人，就是杨燕的那些固定嫖客中的一人。很巧，这个人就是报案人包林傲。当时我们认为他之所以报案，是因为贼喊抓贼。人到公安局后，就一直在喊冤枉。他承认自己在23日晚上十一点，按照约定去杨燕家和杨燕发生了性关系，支付了两千元后就离开了。离开的时间是晚上十二点。” “根据死亡时间，这个时间，杨燕确实还没有死。”吴响说，“目前看，应该是深夜一点到两点之间死亡的。” “重点是这个包林傲是个有前科劣迹的人。”我说，“一来他这个年纪了，二来经过打击处理会有经验，不会出现现场这么幼稚的行为。他确实应该是被冤枉的。” “那么，下一步我们该如何去查？”强局长问道。 我摸了摸下巴，说：“未成年人，怎么会想起来做强奸案件？这让我突然想起一个星期之前，我们正在侦办的那起'清道夫专案'。” “哦？说说看。”强局长饶有兴趣。 我说：“'清道夫专案'在一星期之前发生了第五起。这一起与以往不同，有一个目击证人目睹了凶手杀死被害人的全过程。你们知道这个叫作狗蛋的孩子，为什么会目击到这一切吗？” 大家都摇摇头。 我说：“他听见死者房里有女人的声音，认为死者正在嫖娼，所以想去偷窥。” “偷窥？”强局长说，“你是说，这起案件也有可能是偷窥引发的？” 我点点头，说：“我看了原始现场照片，现场那幅窗帘，并没有完全拉上。也就是说，在屋后，可以看得清楚屋内的一切。加之未成年人作案，大部分都是有特殊情况的刺激，无预谋、临时起意的。” “我现在好像明白你为什么要坚持提取死者肚皮上的精斑的原因了。”吴响说道。 我抬腕看了看表，说：“现在DNA结果也应该快出来了，不如大家就抓紧在现场周围排查十三四岁以上的未成年男性吧。既然有条件通过窗户偷窥到现场正在发生的卖淫活动，说明这个未成年人有条件经过现场窗下。这一片居民区相对封闭，所以这个嫌疑人肯定是住在现场周围不远的地方，范围不大。” “如果这样说，我这里倒是有一条线索。”一名侦查员突然说，“现场周围最近的、最符合条件的人员，就是死者隔壁吕氏夫妇家的双胞胎儿子。据吕氏夫妇说，当天晚上从十一点开始，到第二天早晨六点，他们都在市区卖夜宵。为了核实吕氏夫妇的言辞，我们对夜宵街附近进行了走访，验证了吕氏夫妇所说，他们确实在夜宵街卖了一夜夜宵。不过，被走访的人反映，他们只看到吕氏夫妇和其中一个儿子，并没有印象双胞胎都在。当时我觉得这俩孩子就十五岁，还是比较贪玩的年纪，跑出去玩也很正常，就没有在意。” “也就是说，不仅这两个孩子中的一个有作案时间，而且吕氏夫妇在此事上还说了谎？”强局长说，“结合秦科长刚才的分析，这两个孩子中的一个有重大作案嫌疑。抓紧时间，迅速行动，慎重审查。” “等等。”我说，“现在看起来有个问题比较棘手。就是如果两个孩子是同卵双生的双胞胎，那他们的DNA就是一致的。” “一致的就一起抓。”强局长说，“如果DNA比对上了，就是他们俩，还能逃得脱法律的制裁吗？” “可不是这样说的。”我说，“即便DNA对上了，不能说清楚两个孩子谁才是凶手的话，根据无罪推定的原则，两个人都会被判无罪。” 大伙儿都闷不吭声了。 只有林涛兴高采烈地举起手中的指纹卡，说：“幸亏有咱们秦科长的未雨绸缪，幸亏有我这台精密的提取仪器。我们在死者家里的电脑主机电源开关上，提取到一枚指纹。根据之前的分析，这枚指纹应该是凶手在开启电脑的时候留下的！” 全场一片沸腾。 强局长做了个安静的手势，说：“第一组，马上觅取两名嫌疑人的食指指纹，进行比对。双胞胎就想逃脱法网吗？你们的指纹不能是一样的吧？” 吕文和吕武虽然是同卵双生的双胞胎，但是性格迥异。吕文性格文静，勤奋好学，而吕武生性懒惰，轻浮狂躁。从同一个班级出来，成绩却是天壤之别。同样刚刚经过中考的他们，一个考上了市里的重点高中，而另一个只有去技校学习。 在DNA比对结果出来之前，指纹已经验证了吕武是本案的凶手。虽然油嘴滑舌的吕武一直在辩解说自己曾经到杨燕姐姐家里玩过电脑，但是当杨燕腹部的精斑也和他比对一致时，他再也无话可说了。 7月23日晚，吕氏夫妇带两个儿子去摆地摊，没摆到半个小时，吕武就嫌太累，要求回家睡觉。吕氏夫妇对自己的这个小儿子没有什么办法，就让他回去早点儿睡觉，不要乱跑。 十一点三十分，吕武回家路上经过杨燕家窗口时，感觉到了窗户里有人影在闪动，于是扒在窗口偷窥。 窗内的春色，让这个刚步入青春期的少年垂涎欲滴。 在屋内的男人离开后，吕武经过了激烈的思想斗争，最后决定也去一试。为了防止被杨燕轰出屋外，他先回家找了一把匕首揣在身上。 零点已过，吕武敲响了杨燕家的房门。杨燕很警惕，没有开门，只是隔着猫眼，问这个邻家的男孩为什么深更半夜到自己家里来。 吕武则装出一副苦脸，说自己的母亲病了，父亲和哥哥不在家，请求杨燕帮忙去看看。杨燕知道平时这对夫妇对自己总是笑脸相迎，不是什么坏人，加上门外的这个半大男孩，看上去也没什么好害怕的，所以就打开了厚重的防盗门。 吕武猛地迈进屋内，反手关上房门，要求杨燕也像对待刚才那个男人一样对待自己。杨燕先是一惊，随后则恼羞成怒，说你这个半大孩子怎么这么没教养？不仅偷窥别人，还提出非分的要求。 “毛都还没长齐呢，你想些什么呢？”这一句话激怒了吕武。 随后吕武和杨燕发生了激烈的打斗，杨燕以失败告终。 在掐晕杨燕后，吕武扯开了她的衣服。因为没有经验，在反复尝试后，并没有得逞。于是他对着地板上赤裸的杨燕手淫。 完事后，杨燕仿佛还有些清醒，吕武害怕事情败露，突然想起他还带着一把匕首呢，于是掏出匕首刺到了杨燕的颈部。一刀下去，血液喷出老高，这一下把吕武吓坏了，赶紧拽过床上的被子掩盖住了尸体。 吕武去卫生间洗干净了手，有些不知所措。于是打开电脑，在网上寻找犯罪后逃避打击的办法。 最后，他按照网上教授的办法，仔细打扫干净现场的血迹后，匆匆离开。 第二天，吕氏夫妇回到家里后，发现了吕武换下来的衣物上的血迹。他们刚把衣物清洗干净，就听见门外有嘈杂声。吕氏夫妇的心里，很快就有了答案。在警察到达前，他们商量好了对策，匆匆躺上了床，假装熟睡。 “犯罪的低龄化，实在让人有些触目惊心。”我摇摇头说，“以前看过半大的男孩强奸幼女的案件，现在这直接上升到强奸、杀人的地步了。” “我倒是一直很纳闷，同样的家庭、同样的学校，居然能教出两个完全不同性格的孩子。这两个孩子还是双胞胎，按照基因看，也应该相似才对。这让我不得不开始怀疑'人之初、性本善'的说法了。”陈诗羽也感叹道。 “不管怎么说，这个案子是破了。”林涛重重地关上警车的门，对韩亮说，“赶紧走，赶紧离开这里。丽桥市是我最不喜欢的城市，没有之一。” “为什么？”陈诗羽问道，“我觉得这里古色古香，生活节奏又悠闲，多美好啊。我以后退休了一定要来这里定居。” “你才多大点儿啊，就想退休的事情了？”我靠在副驾驶座位上，笑着闭上眼睛，说，“林涛讨厌这里，是因为一年前的一桩命案，迷巷鬼影。” “鬼影？”陈诗羽惊讶地说，“你们见着鬼了？” “天要黑了，别说了行吗？”林涛抱了抱肩膀。 我说：“是啊，是一个白衣长发的'女鬼'。” “白衣长发？”陈诗羽思忖片刻，说，“和'清道夫专案'有关系吗？” “对啊，我都没有想到。”我说，“'清道夫专案'也是个白衣长发的女人对吧？不过迷巷鬼影那个案子，不是真的鬼，不是女人作案，是一个人装扮的——等等，装扮……” 我正在低吟，电话铃声突然响了。 “听说破案了？效率真高。”大宝的声音，“回来了吧？回来后，直接到师父办公室。” “师父办公室？”我说，“我们估计要晚上八九点钟才能到哦。” “不管几点，我在师父办公室等你。”大宝急急地说。 “好，我们到达后，直接过去。”我说。 “不，不对，不是你们。”大宝说，“就你一个人来，别人都别带来，切记。” 我的心里有些不祥之兆，从后视镜看了看后排林涛和陈诗羽正在嬉笑打闹，默默地挂断了电话。
