Chapter 5 Chapter Four: Shadow in the Window

Summer continues.The temperature has exceeded the normal temperature of the human body, which also provides good environmental conditions for the growth and reproduction of spoilage bacteria.The office workers hid in the air-conditioned room, but the forensic doctors were still under the scorching sun, wading through mountains and rivers, salvaging corpses of various shapes, and moving them back to the autopsy room for examination.It is not an exaggeration to say that the shape of the corpse is different, and the corruption of the corpse is different every day, from the green corpse to the appearance of the corrupt vein network, to the blackening and swelling of the corpse, and of course the giant appearance that is the most headache for forensic doctors.No matter what the body turned into, the forensic doctor couldn't just ignore it, and couldn't fool the task.Therefore, it is very common for grass-roots forensic doctors to suffer from heatstroke and skin peeling.

I am the kind that is not fast to the sun. Every summer and winter, I will appear in two skin colors, and this year is no exception.On Monday, I entered the office in the dark and saw Dabao sitting at his desk eating breakfast. "I haven't seen you for a month, what did you do?" Dabao said, "Is the ticket to Africa expensive?" "Fuck you. I'll be like this in summer." I was also surprised that Dabao came back to work.A month ago, in order to prepare for the selection exam, the master gave him a one-month vacation to concentrate on reviewing.When you see him back, you know his exam is over.

"How did you go?" I asked. "My lord Bao, you did well in the exam. Isn't it the law? It's much easier than the judicial exam." Dabao was full of confidence. Hearing what Dabao said, I was relieved a lot. Since the employer cannot choose the person he uses, the only thing I can do is pray. The phone rang suddenly, Dabao stopped chewing, took a mouthful of food and said: "Isn't that lucky, I have a job on the first day I come out of the rivers and lakes?" "Is it good luck or bad luck?" I frowned and answered the phone. "I'm downstairs, it's very sunny, so if you don't come downstairs within five minutes, I won't take you to this scene in Qingxiang City." It seems that Master is in a good mood recently, not only can he put down the heavy administrative management He can still use such a relaxed tone to tease when he is out on the job site.

After hanging up the phone, I said to Dabao, "The first case you came back from is from your hometown again. Hurry up." In the elevator, Dabao and I met Lin Tao, who was sweating profusely and sleepy. Seeing the suitcase in his hand, I knew we were going to walk together again. "Qingxiang has many beauties." I said with a smile, "It's not your character to appear in this image." Lin Tao shook his head: "Don't mention it. I was on duty last night and answered all kinds of harassing calls all night. I wanted to go to bed later this morning, but Qingxiang called at seven o'clock to say that there was a murder case. No, Yadu Didn't brush it."

"Do you know what the case is?" Lin Tao leaned forward to show off his white teeth. I quickly pinched my nose and walked away, asking. "The phone said that this morning a villager found a beautiful young woman from the neighbor's house dead on his bed. She was naked. It must have been a homicide, so he called the police." Lin Tao took out a napkin and wiped the sweat from his brow. "We are investigating important and difficult cases. Why do we have to go now as long as it is a beautiful young woman? If you want to mobilize people, even the master will go?" Dabao said.

"No, I haven't finished yet!" Lin Tao breathed out long enough, "When the police from the police station arrived, they found a naked old man in another room, also dead." "Same family?" I asked, thinking that sleeping naked is so popular now? "Probably." Lin Tao said, "Mr. Chen asked to go. For such an expert, asking him to do administration every day is like forcing southerners to eat pasta every day. It's unbearable." The master was looking at his watch downstairs, and when he saw us coming, he said with a smile, "Four minutes and forty-nine seconds, it's almost nothing for the three of you."

As soon as I got into the car, I couldn't help asking: "Master, do you have any information?" Knowing the situation at the scene earlier will give the on-site investigators more time to think, and perhaps with this extra time, they will be able to find the key to solving the case. "It is estimated that the difficulty will not be too great." The master said slowly, "Based on the preliminary investigation, both the father-in-law and the daughter-in-law died. The nature of the death is not clear at present. It is said that there were slight signs of fighting in the family."

"It can't be incest, right?" I sweated secretly. "What's going on in your mind? Have you watched too many Japanese movies?" Master said. I muttered: "What Lin Tao said was naked death." Lin Tao stared and spread his hands to show his innocence. Master said, "The male deceased suffered a cerebral hemorrhage a few months ago and is currently in a semi-vegetative state." "Oh." The three of us sitting in the back row said in unison.I thought to myself, what kind of person is so ruthless that even a vegetable will be killed?is it necessary?It must have been a deep hatred.Maybe it was due to the grudge against the male deceased, but the female deceased was just unlucky to meet.But if I were the enemy of the dead man, instead of killing him, I might as well just watch him in a vegetative state, how relieved I am.

Along the way, Dabao and I were arguing about his selection exam questions, while Lin Tao slept soundly on the back of his chair. "He hasn't found a girlfriend yet?" The master sitting in the co-pilot looked back at Lin Tao and said to me. "How do you know?" I said, "Master also gossips." "Nonsense." The master said, "My soldier's family issues are very important. I care about my subordinates. How can it be gossip? The reason why I know he doesn't have a girlfriend is because of observation. You see, as soon as you get in the car, you and Dabao are alone. If I guessed right, it should be to report to my girlfriend that you are on a business trip. But Lin Tao fell asleep as soon as he got in the car."

Dabao and I were speechless immediately, wondering if this is the case, on-site analysis is everywhere? After getting off the expressway, I saw a car from the Qingxiang City Public Security Bureau waiting there with its lights flashing.Liu Detachment saw that the person sitting in the co-pilot was Master, and hurried over to salute: "Mr. Chen, is Mr. Chen coming in person?" "Oh, I'm here to test whether these boys have made progress recently." Master pointed to us and said. Dabao and I looked at each other, thinking, this master, if I can't hold it back, I can't hold it back, and I need to find a reason for appearing on the scene.

Under the leadership of the police car, we passed through the bustling city center, and after some bumps, we arrived at a small village on the outskirts of the remote city.The road in the small village is very narrow, and more than a dozen police cars are parked at the entrance of the village. We got out of the car and walked towards the center site with our suitcases. I quite like the feeling of walking through the crowd with a suitcase, listening to the discussion of the crowd, and bathing in the admiring eyes of young girls.Although I know that the girls are more willing to stare at Lin Tao than me, the black Baogong. The site was a well-built courtyard, and there was a one-story house with white bricks and black tiles in the courtyard.The bungalow has only one door, but judging from the peripheral windows, there should be a living room and two rooms. Liu detachment called the investigators who were in charge, and introduced the investigation situation in the early stage of the case to us. "At seven o'clock in the morning, the old lady from the next door to the scene called the police. The old lady said that the owner of the house is Kong Wei, who spent all his savings to buy a daughter-in-law two years ago. It is said that the price is indeed not cheap, because Everyone in the village knows that the daughter-in-law bought by Kong Wei is very beautiful. This daughter-in-law's surname is Cai, and everyone calls her Xiao Cai. Xiao Cai is from Yunnan. She is introverted and cautious, and generally does not deal with others. The door is locked every day, and it is difficult for everyone to see her. But this morning, the door of her house was concealed, and the old lady thought it was strange. When I got out of the yard, I saw that the door was also open, and felt that something was wrong, and when I entered the living room, I saw Xiao Cai dead on the bed." "Where is Kong Wei?" Master asked. "We are looking for it," said the investigator. "According to the investigation, Kongweituo's relatives helped him find a good job in Shanghai half a year ago, so he has been working there and rarely comes back. Three months ago, Kongweituo Wei's father, Kong Jinguo, had a sudden cerebral hemorrhage, although he was sent to the hospital for emergency treatment and managed to save his life, but because of the late discovery, he basically became a semi-comatose state of a vegetative state, without the ability to take care of himself." "Kong Wei came back at that time?" "Yes. Kong Wei came back the next day. He knew that his father became a vegetable because Xiao Cai found out too late, so he beat Xiao Cai so angry. He took care of his father and left the hospital before returning to Shanghai. In the days that followed, Xiao Cai will take care of Old Kong." "Kong Wei is also a dutiful son. How is Xiao Cai taking care of the elderly?" I asked. "Because Xiao Cai generally doesn't deal with people, everyone is not very clear." The investigator said. "Where is Kong Wei now?" I asked. "No contact yet." I shook my head, thinking to myself, how would this dutiful son feel if he learned that his father and the beautiful daughter-in-law bought with money died at the same time. Master beckoned us to put on our survey suits and enter the scene. After entering the gate, you can see a spacious living room. There is not much furniture in the living room, only a one-piece sofa and a wooden dining table are placed.There are doors on the east and west sides of the living room, leading to the east and west bedrooms respectively.The items in the bedroom on the west side were neatly arranged, and there were some signs of fighting in the bedroom on the east side, but there was no sign of the wardrobe or cupboard being turned over. "The doors and windows are in good condition, and there are no signs of prying." "Look at the condition of the corpse first, and then analyze the scene." Master saw Lin Tao and several trace inspectors investigating the scene, so he turned to me and Dabao and said. We entered the bedroom on the east side, and there was a naked female body lying on the bed. Her skin was very white, pale, and she had a good figure. She was indeed the beautiful young woman that the villagers said.Red spots had formed on the underside of the deceased's body.A torn dress and a pair of white underwear were strewn about on the inside of the bed. "It looks like a rape scene." My voice was reduced by a lot of decibels through the mask. Master nodded and said, "Look, the corpse spot is tough, but the corpse has not reached the state where all the joints are the hardest. How long has it been since death?" "About ten hours." I said while looking at the thermometer inserted into the anus of the corpse, "According to the temperature of the corpse, it was eleven hours after death. It is almost eleven o'clock now, that is to say, Xiao Cai's The time of death was around twelve o'clock last night." The master said: "Yes, he died at twelve o'clock last night. As I said just now, Xiao Cai was very cautious, and there was no one with whom he had a good relationship in the village. The door at the scene was concealed and the windows were closed. If rape, rape How did the prisoner enter the scene at such a late hour? Xiao Cai is so cautious, she won’t stay open in the middle of the night.” I bowed my head in thought. The master said, "Go and see Lao Kong's body." We walked back to the living room, and Lin Tao was looking for footprints at the door of the bedroom on the west side. When he saw us coming, he said, "Didn't you talk about what happened last night? Why does the corpse stink? It won't decay so quickly, right?" I smiled and said, "Didn't you brush your teeth? You can't smell your own scent, can you?" Lin Tao stood up and punched me with a fist. "Lin Tao is right." Master said, "It seems that this case is complicated." "What's a good statement?" I walked over to look at the body. Lao Kong's body was covered with a towel blanket. His eyes were slightly open, his lips were slightly parted, and there were several abrasion-like marks on the corners of his mouth. "This is really strange." Master said, "Old Kong seems to have died a day earlier than Xiao Cai." I lifted Lao Kong's arm and said, "The degree of rigor is about the same as that of Xiao Cai." Master said, "Don't jump to conclusions first, just look at this." The master casually lifted the towel blanket, revealing Lao Kong's belly. "The arms and legs of the deceased showed obvious muscle atrophy." I said, "but the stomach is still quite big. It seems that this little Cai is doing his best to take care of Lao Kong." "That's not the point." The master said, "Look at Lao Kong's abdomen has turned green, and the network of corrupt veins has begun to appear, but Xiao Cai's has not." "Understood," I said, "rigor rigor is slowly formed and then gradually relieved. To distinguish whether rigor rigor of this intensity is in the forming period or the remission period depends on the degree of corruption of the corpse. Green corpses appear, It should be more than a day." "Yes, based on the comprehensive consideration of the rigor and corruption of the corpse," the master lowered his head and thought for a while, and said, "Old Kong should have died the night before." "That is to say," I said, "Old Kong died a day earlier than Xiao Cai. What's the situation?" "What is this?" Dabao's words interrupted Master and I's thinking. I turned my head and saw that Dabao was holding the largest syringe in his hand, and said, "There is a syringe on the bedside table. Lao Kong is in a semi-vegetative state, so there is no need for an injection, right? Besides, you don't need such a big injection." Syringe?" "Could it be that he died by injecting poison?" I said. The master looked around the bedside table and said, "It doesn't look like it. No needles were found nearby, and it doesn't look like they were used for injections. Go back and pay attention to whether there are needle holes on the corpse, and then conduct a poison test." I took the syringe and found that there seemed to be some residue in the needle tube. After shaking it, I found that it was mainly liquid, but there were obvious impurities in it. I put the needle tube into the evidence bag, handed it to Lin Tao, and said, "Go back and test to see what's inside." Master took us back into the east bedroom and began to investigate more carefully. The scene was very simple, and I learned from Lin Tao that no valuable fingerprints or footprints were found.A telephone was scattered on the ground, completely damaged.The air conditioner above the bed was still blowing cold air, but the blades of the air conditioner had already fallen on the pillow, and Xiao Cai was under his head. I brought a bench and stood on it to observe the air conditioner. "There are obvious signs of damage on the outside and bottom of the air conditioner." I said, "It should be that a hard object hit here, and the plastic cracked, so the flap that was fanning fell on the pillow." "It was probably hit by this thing." Dabao pointed to the telephone on the ground beside the air conditioner. "Besides, things are smashed first, and people lie down on the bed." The master pointed to the leaf board under the head of the deceased and said, "This leaf board indicates the order." We all nodded. "We will search carefully on the phone later," Lin Tao said, "to see if there is any possibility of finding fresh fingerprints with identification value." The master squatted on the ground and picked up the phone, and said to Lin Tao: "The key is the base surface of the phone. Think about it, if you want to throw the phone out, your fingers will definitely touch the base. If there are fresh fingerprints on the base, then the fingerprints The owner is seriously suspected." Lin Tao nodded and said, "We'll send the phone for testing right away, and the results will be available in about two hours." Master said, "Okay, let's go to the funeral home first." Along the way, I was thinking about the death of Lao Kong.The old man had slender limbs but a big belly.The key is that the deceased was naked, no fatal injury was seen, and there was no obvious sign of suffocation.This patient with cerebral hemorrhage will not die naturally, right?If it was a natural death, why didn't Xiao Cai go to other villagers for help?Putting a dead person at home for a day, a woman probably doesn't have the guts to do that? Soon we arrived at the funeral home.Forensic Doctor Sun from the Qingxiang Public Security Bureau was already waiting in front of the dissection room. The anatomy room in Qingxiang is the leading one in the whole province, but before the master could open his mouth to praise, Fayi Sun said with apology: "The fresh air system in the anatomy room was broken two days ago, and now the exhaust and air conditioners cannot be used. It's like a steamer right now." I walked into the dissecting room and felt the temperature. It was indeed like getting into a car that had been in the sun for a day without window film. There was a buzz in my head, so I quickly backed out. The master shook his head helplessly, and said, "Let's find someone to repair it as soon as possible. It seems that we only have an open-air autopsy today." "Master, who shall we start with?" I put on my stuffy dissecting suit and found a shady place to stand. "Let's look at Lao Kong first," the master said, "I have been thinking about the cause of this Lao Kong's death all the way." I was secretly happy that my thinking and Master's thinking were so highly unified. Dissection begins shortly.We cut open the dead man's scalp and found that the dead man's skull was missing a piece, and the edge of the broken end of the skull was blunt, which should be formed by the operation performed by the hospital to remove the hemorrhage in the brain. The lack of this bone flap saves a lot of trouble for the craniotomy. We opened the dura mater where the old hole had been sutured, and the inside of his skull looked clean. "It can be ruled out that the recurrence of cerebral hemorrhage died." The master said, "There is nothing wrong with the head." "The neck is fine," I said, "and there are no obvious signs of choking." "That... is more like... a natural death." Dabao's weak voice caught our attention. I saw Dabao's face was pale, and there were beads of sweat dripping down on his forehead, so I hurriedly asked, "Dabao, are you alright?" Dabao shook his head and said, "I have some symptoms of heatstroke, and I will be fine in a while." After speaking, he walked to the side and stayed under the shade of a tree. Master returned to the topic and said, "From my analysis, this little Cai should take care of the old man wholeheartedly." "Where can you tell?" I asked. "I also guessed." The master said, "If the father-in-law and daughter-in-law are in the same room, and the father-in-law has no ability to take care of himself, the daughter-in-law can let the father-in-law naked when he is out of the house, it is only for the convenience of wiping the father-in-law." I nodded and said, "Yes, it's summer after all. And this old Kong doesn't have any peeling or abscess on his body, which is difficult for people who have been bedridden for a long time. It should be kept clean all the time." "Maybe it was really a natural death." Master said. Just as he was talking, the sky was suddenly covered with dark clouds, and raindrops fell without warning.We hurriedly pushed the body into the stuffy dissecting room, and forensic doctor Sun Zhangluo helped the policeman who was taking pictures to open the window. "It doesn't look like a natural death." The master said with a smile, "You see, God has opinions, and they have made wind and rain." My back was in a cold sweat when Master said: "Master, we must talk about science, not feudal superstition." The master laughed loudly and said, "I see you are so serious, Dabao is so serious that he has sunstroke, so it's fun to talk about it." As the rain fell, the air immediately became much cooler. I stood by the window and enjoyed the wind blowing on my back.Dabao's pale complexion also eased a lot with the cool breeze. But when Master's scalpel cut through Lao Kong's abdomen, we were all stunned. As the skin under the knife parted to both sides, what jumped into the eyes was actually a belly full of yellow.There are no internal organs, no small intestines, the yellow color in front of my eyes is shocking, and the smell is even more pungent.It's not an exaggeration at all, it's full of... something like feces. "This... what is this..." I raised my elbow and rubbed my nose, and said, "Could it be that the internal organs are corrupt?" Master turned to look at me and said, "Have you ever seen internal organs rotted like this?" "I've never seen a belly cavity like this before," I shook my head and said, "Could it be a belly full of shit?" The master said: "It is indeed rare, but now that we have figured it out, we directly opened the stomach of the deceased." "Stomach?" I know that the human stomach is flexible, and it is located directly behind the abdominal cavity. Generally, it will not be easily cut open by a scalpel. "Yes." The master used the hemostat to pinch a thin layer of soft tissue and said, "Look, this is the stomach of the deceased." "Understood." I said, "There was a large amount of material in the deceased's stomach, which stretched the stomach to its limit and stuck to the abdominal wall, so we cut the stomach open with one knife." Master said: "Yes, the chyme in the stomach should keep the original color of the food, but the stomach of the deceased is like feces. Freezing three feet is not a day's cold." "You said that so much chyme was accumulated over time," Dabao asked, "and then the chyme was digested and decomposed into feces?" "Yes." The master cut off and straightened the small intestine along the mesentery of the deceased, and said, "Look, there is an intussusception here." "Intussusception can cause most of the intestinal obstruction." I said, "It means that the deceased eats a lot every day, but pulls out less. Over time, the stomach will become bigger and bigger." "Unfortunately, he can't speak after cerebral hemorrhage," the master said. "He can only eat when others feed him." "Wouldn't it be fine if you didn't open your mouth?" Dabao said. "I'm afraid that some kind-hearted people did something bad." The master pointed to Xiao Cai who was lying on the side, and said, "Did you forget that syringe?" "Oh," I suddenly remembered the large syringe, "I was afraid that the old man would not be full, so I used the syringe for gavage. Once the old man opened his mouth, he couldn't stop, so he could only continue to swallow." "We'll find out when the residue in the syringe is tested," Master said. "Because the stomach of the deceased continued to grow, it oppressed the important blood vessels and organs in the abdominal cavity, resulting in insufficient blood supply to various organs, and eventually the compression reached a certain level, and organ failure led to death." I said, "So it looks like Natural death." Dabao said: "Well, it turns out that there is such a mechanism of death, I didn't know it before. However, Master's feudal superstition has really come true." I looked around and felt as if someone was watching me. "The liquid in the syringe is rice soup, and the impurities are rice fragments." Liu Detachment walked into the dissection room at this time and said, "In addition, the fingerprints of four fingers were indeed found on the base of the telephone at the scene. The fingerprints found on the website are consistent, so it can be confirmed that it belongs to Xiao Cai." "Well, I think it should be the same." The master said, "From the inspection just now, the deceased was given food by syringe for a long time, but due to intussusception, he could not defecate normally, which caused excessive gastric dilation, compression of abdominal veins, and visceral organs. Insufficient blood supply to organs and death due to functional failure.” Hearing Master Hulala say a lot, Liu Zhipi rolled his eyes upwards, obviously unable to react. "Fucking." I added. Team Liu suddenly realized, nodded and said, "It turns out that the murderer is Xiao Cai." "She should have been unintentional." The master said, "Judging from Lao Kong's body, his body should have been kept clean during his lifetime, without any bedsores. This shows that Xiao Cai took care of him with all his heart and should not have killed him." It may be because Xiao Cai didn't know some common sense, so she accidentally killed her father-in-law." "I heard you say that," said Liu Detachment, "Could it be that Xiao Cai found out that the father-in-law he took care of was dead, and committed suicide because of guilt?" "Think of something good." I said, "Well, you don't have to stay up all night, right?" Liu Detachment laughed at the side. At this time, forensic doctor Sun and the intern forensic doctor had replaced the corpse on the dissection bed with Xiao Cai.The master went over and examined Xiao Cai's body form in order from head to toe. "Spotting of the conjunctiva, bruising of the lips, bruising of the cheeks, and cyanosis of the nail bed." Master said, "The signs of suffocation are obvious." "There are obvious strips of subcutaneous hemorrhage in the neck." I pointed at the neck of the deceased with a hemostat, and said, "Basically, he was strangled to death." The master smiled and said to Team Liu: "It seems that your wish has been shattered. There are many ways to die, but strangulation is something you can't do yourself. Xiao Cai died of homicide." Although the cause of death has been basically clarified, Master still led us to conduct an autopsy on Xiao Cai's body according to the autopsy procedure.When the corpse moved a little, yellow-white liquid flowed out from the perineum. I took gauze wrapped around the hemostat and took a vaginal swab of the deceased. "It must be semen, and there is a lot of it." I frowned and said, "The opening of the vagina is swollen, and the inner wall is obviously scratched. This is a very rough sex." "The autopsy will be over in a while, and I'll send it for inspection." Seeing that everyone is busy, the master said. "It is highly suspected that it was a sexual assault." Dabao said, "The deceased was strangled to death, with slight restraint injuries on the wrists, a large amount of fresh semen in the vagina and vaginal injuries, and small flakes formed by extrusion on the back and shoulder blades. Bleeding. It is completely in line with the injury characteristics of the deceased in the rape and homicide case." "But Master said," I said, "Xiao Cai is a cautious person, and generally would not open the door to strangers in the middle of the night, and Xiao Cai has no acquaintances." "This case needs to be looked at together." The master frowned and said, "The timing is very special. Xiao Cai died on the second night after Lao Kong died. Lao Kong died the night before, and Xiao Cai died the night before. Cai discovered that Lao Kong’s death should have happened yesterday during the day, and she was attacked last night. There shouldn’t be such a coincidence, and the two events should be inextricably linked.” "How to get in touch?" I felt my mind was confused, "If we insist on getting in touch, then only her husband can do it." "Yes, her husband." Dabao said, "Why can't her husband do it?" Supporting the dissecting table with both hands, I recalled the situation at the scene and said, "Now that I think about it, it's very likely that her husband did it." "Then tell me about your basis." Master began to ask questions. "First, after investigation, Kong Wei is a so-called filial son, because the old man would beat his beloved wife when he was hospitalized. If he finds out that his father was fed to death by his wife, the consequences can be imagined." I said, " Secondly, I recalled the situation at the scene. At the scene, there was a process of smashing home appliances first, the air conditioner was smashed, and then the neck was strangled. It’s still on the pillow. Now it’s confirmed that Xiao Cai used the phone to hit the air conditioner so high. Usually it’s when husbands and wives quarrel and fight. Go? To put it bluntly, the scene was a husband and wife quarrel, and Xiao Cai smashed the air conditioner with a telephone, and then was pushed down on the bed and strangled to death. Then her husband is obviously suspected of committing the crime." "How do you explain the sexual behavior and vaginal damage?" Dabao asked. I said: "It's normal, the vaginal injury has a living reaction, and a large amount of semen has not been lost. It means that the deceased was raped while alive, and then directly strangled to death. In other words, after the sexual act, the deceased did not have a position Change, otherwise the semen will flow to other places, there will not be so much. As for the damage and clothes being torn, I think it is understandable. Kong Wei has been working outside for a long time and lacks sex. After returning, his wife was so angry that he went up and raped Not impossible." "Does Kong Wei know that his father is dead?" Dabao asked. "I think I should know. You see, it is not a holiday, nor is it a busy farming day. It is a good time to work outside to earn money. What is he doing when he comes back at this time?" I said, "The biggest possibility is that Xiao Cai found out that Lao Kong was dead. , and called Kong Wei back. The time was also right." "I'll ask them to check the call records." Liu Detachment went to the side and arranged for investigators to check the call records of Xiao Cai and Kong Wei. "You are very reasonable." The master finally said, "The previous analysis is well-founded. Now we should immediately find Kong Wei and conduct a DNA test on his semen. Anyway, Kong Wei should be directly related to this case. As for whether it is true or not?" Kong Wei did it, I still have a lump in my heart." "What lump?" Dabao and I asked in unison. "I can't tell right now." Master said, "You go to the DNA test first, and I'll try to figure it out." Dabao and I drove to the DNA laboratory of Qingxiang Public Security Bureau.Ms. Zheng, a DNA tester at the Qingxiang Municipal Bureau, is the first generation of DNA test staff in our province and has very rich experience. Sister Zheng saw us coming in and said, "What a coincidence. The DNA profiles of Kong Wei, Kong Jinguo, and Xiao Cai have just been released. Kong Wei's DNA was extracted by investigators at Kong Wei's home, and there are conditions for comparison." "Kong Wei hasn't been at home for half a year, is the DNA extracted at his home reliable?" I asked. Sister Zheng said: "I have also considered this, and compared the samples, and I can confirm that it is the son of Kong Jinguo." I nodded, admiring Sister Zheng for her thoughtful thinking: "Sister Zheng, this is the vaginal wipe of the deceased woman, Xiao Cai. We are currently analyzing that Kong Wei is suspected of committing a major crime, and Xiao Cai has never gotten up from the bed after having sex. , so this semen is likely to be Kong Wei’s semen.” "Okay," Sister Zheng said after taking the inspection materials, "I need six hours." "Master told us to wait for the result here." I said with a smile, "Because the result is out, it is very likely that the case will be solved. In addition, I happen to have a question to ask Sister Zheng." "What's the problem?" Sister Zheng asked curiously. "You should be busy first." I said, "This case is a big deal. You will be free when you finish collecting materials, loading samples, and doing sample amplification. I will ask you later." Sister Zheng nodded with a smile and said, "Okay, just wait." After speaking, she turned and walked into the exquisitely decorated DNA laboratory through the access control system. Dabao and I saw that the staff in the DNA room started to get busy, so we lay down on the chairs outside the laboratory door.Because we were tired all day, after a while, we both fell asleep in a daze. After sleeping for about three hours, I was woken up by Sister Zheng. I wiped the saliva from the corner of my mouth and said, "Huh? Sister, the sample has begun to increase?" Sister Zheng said with a smile: "It has been enlarged a long time ago. Seeing that you are sleeping like that, I can't bear to wake you up. Tell me, what questions do you want to ask me?" I glanced at Dabao who was still soundly asleep, and said, "He almost suffered from heat stroke today, let him sleep a little longer, let's go to the office and talk about it?" When I entered the office, I got straight to the point: "I came across a case, which was a series of cases. In several cases, the deceased was raped, and the vaginal swabs of the corpses were all found to be weakly positive for semen spots, but they couldn't make a diagnosis. The DNA genotype of the criminal, what would that typically look like?" "You mean the 'Yuntai Case'?" Sister Zheng said with a smile. "You also know about this case!" I was very surprised. "I know, I was also invited to consult at that time." Sister Zheng said, "When the first case happened, the DNA technology was not very mature, and everyone thought it was a problem with the machine. But then there were a few more cases, especially one Together in Longdu two years ago, the genotype could not be detected, but now the DNA technology is very mature, so it will not be a problem of technology and machines." "Then what do you think is the reason?" "Acid phosphatase in semen can decompose disodium phenylphosphate to produce naphthol, which is combined with aminoantipyrine through the action of potassium ferricyanide to produce red quinone compounds. This is the principle of the seminal spot pre-test." Sister Zheng said, "Since the seminal speckle test is weakly positive, it means that the deceased definitely had seminal speckles in the vagina. Generally, in such cases, we are sure to make a DNA typing." "Then why didn't it come out?" I asked, "Isn't it a human semen spot?" I regretted it after asking.Sister Zheng was only about forty years old, and her face flushed suddenly. "No," Sister Zheng said, "Animals can also be genotyped." "What could be the reason?" I couldn't figure it out. Sister Zheng went on to say: "At that time someone asked if he was wearing a condom." "If you wear a condom, you won't have a weak positive." I said. "Maybe I didn't wear it at the beginning, but I wore it later." Sister Zheng said, "If that's the case, there may be a very small amount of semen left, but no sperm. You know, it can only be detected when there is sperm. DNA." I nodded and said, "Yes, besides wearing a condom, there is also the possibility of ejaculation outside the body." "But both possibilities have been ruled out." Sister Zheng said, "First of all, the vaginal swabs of the deceased did not detect the oil on the outside of the condom, which means that the condom must have been worn. Secondly, the vicinity of the scene and other parts of the corpse were No semen spot was detected, where did the ejaculation go?" Sister Zheng went on to say: "I'm not a doctor, so I don't know much about medicine. Someone suggested that there is a disease called non-ejaculation." "No." I interrupted Sister Zheng, "If you don't ejaculate, you can't get sexual pleasure. It's impossible for such a person to rape and kill one after another. By the way, is ligation possible? Ligation is to cut off the vas deferens, so that the sperm cannot be discharged. But the prostate can secrete semen, and the enzymes detected in the seminal spot pre-test are the enzymes in the prostatic fluid. If it is a ligated man, the excreted prostatic fluid can be positive in the pre-test, but because there is no sperm, there is no DNA typing.” Sister Zheng said: "You are very smart. At that time, many people thought about it for a long time, and finally came to the conclusion that this man had undergone circumcision, but I have always disagreed with this statement. For one thing, there are very few men in rural areas who have undergone circumcision, and they are all women. Ligation, because the birth control ring worn by women is reversible and can be removed, but not for men. Second, even if it is ligated, the secretion of prostatic fluid should be a large amount, and weak positive results should not be detected. " "It's hard to say," I said, "maybe the criminals washed the vagina of the deceased?" Sister Zheng said, "That's the only way I can explain it." Xiao Wu from the DNA laboratory walked into the office at this time and said, "Section Chief Zheng, the DNA test results have come out. After comparison, sperm spots were detected in the body of the deceased. However, it is confirmed that it was not left by Kong Wei." "What?" I was taken aback, the result was beyond my expectation, "Then, who could it be?" "I don't know at the moment." Xiao Wu said, "I'm sure it's not Kong Wei and Kong Jinguo's. It's hard to say whether other suspects can be linked together. The data is currently being compared in the system." 我昏昏沉沉地和大宝一起回到了专案组办公室。此时夜幕已经降临，但专案会还没有开始，师父一人在电脑前翻看着现场和尸体的照片。 “师父，精斑居然不是孔威的，也不是孔晋国的。”我垂头丧气地说。 师父抬眼瞥了一下我们，说：“我早说嘛，我心里就是有个疙瘩。” 我见师父并不惊讶，说：“可是我觉得我们开始的分析没有错啊。现场那样的打斗痕迹应该是夫妻吵架才会出现的痕迹，对物不对人嘛。” “我很赞同你的分析。”师父说，“但是即便现场有夫妻打斗的痕迹，也不能推断小蔡就是被她丈夫杀死的。” 我点点头说：“按理说是这个逻辑，但是空调叶板被砸下掉在枕头上后，并没有被收拾、拿走。通过死者体内精斑大量存在的现象分析，小蔡被强奸以后，直接就被扼死了，没有体位变动。说明夫妻打架后到小蔡被杀之间的时间并没有多久。” 我顿了顿，接着说：“关键是小蔡身上没有威逼伤，一个杀人凶手可以在被害人丈夫在家的时候，深更半夜，进入室内，强奸杀死被害人？这说不通啊。” “你的假设就错了。”师父说，“精斑的主人和小蔡发生性关系的时候，孔威肯定不在场的。我觉得你分析半天，有点儿乱，我给你捋一捋。” 我点点头，确实觉得自己的思路乱了。 师父说：“现在我们知道的是，一、小蔡很有可能和丈夫发生了打斗；二、小蔡被人扼死；三、小蔡和一个陌生男人发生了性关系。” 师父喝了口水接着说：“那么就有两种情况：一是小蔡有姘夫，关系被孔威发现，孔威杀了小蔡。” “不可能。”我打断了师父的分析，“如果是这样，那么有两种可能，一是捉奸在床，二是奸夫走后孔威才回来，那小蔡的体位肯定会有变化，看见丈夫回来，总不会一直躺那儿吧？那她体内不可能残留大量精斑，而且她的衣服不会被撕毁。还有，打斗形成的空调叶板就不会被小蔡枕在头下。” “说得对，所以这一种可能排除了。”师父说，“第二种可能，就是和小蔡发生性关系的人，和杀小蔡的人是同一个人。” “目前看，这种可能性大。”我说，“毕竟衣服撕破、手腕有约束伤、性行为动作粗暴，这都像是强奸。” 师父说：“但是就像你刚才说的那样，小蔡身上没有威逼伤，那么凶手是怎么做到在深更半夜进入一个平时非常谨慎的少妇家里呢？而且还要先进入院门，再进入房门。难道是骗门吗？那这个凶手也太有本事了吧？” “听你们这样一说，”大宝插话道，“只剩下一种可能了。那就是夫妻吵架之后，丈夫弃门而逃，没关好门，犯罪分子趁机溜门入室。” 我和师父都点头表示认可，目前看，只有这一种情况能完全解释现场状况和尸体状况了。 “不过，如果真的是这样，案件貌似就麻烦了，”我说，“除非能在DNA库里比对上人，不然很难破案。” “是啊，”师父说，“这样的话，随机性太大，目标很难锁定。如果要做犯罪分子刻画，除了犯罪分子年轻力壮、是男性以外，其他的刻画都没有依据。” “我们推断得对不对，得看孔威怎么说。”我说。 话音刚落，刘支队推门进来，说：“不早了，你们还在这里啊，快回去休息吧。” “不是八点半开专案会吗？”师父抬腕看了看手表。 “今晚专案会取消了。”刘支队笑眯眯地说，“孔威被抓回来了。” “抓？”师父问，“你们怎么抓的？” “晚上侦查员在走访的时候，看见孔威一个人正从村口往自己家里走。” 刘支队说，“侦查员上去就摁住了。” “你们也不想想，”师父说，“如果真是孔威杀的人，他会在这个时候回自己家？那不是自投罗网吗？” “怕是你们的'讯问'要改成'询问'了。”我说，“刚出的结果，精斑不是孔威的，据我们分析，基本可以排除孔威的作案嫌疑。” “那你们分析是个什么过程呢？”刘支队问。 “我们就不影响侦查审讯了，省得先入为主。”师父摆手示意让我闭嘴，说道，“你们先搞清楚孔威何时回的家，和小蔡有什么接触过程，今天一天他去哪里了。” 刘支队打开本子，记下师父的话，转身离去。 师父伸了个懒腰，说：“今天挺累的，早点儿回去休息。虽然目前定的是生人作案，但是我心里还是有个疙瘩解不开，解开了，可能会对破案很有帮助。” “师父疙瘩真多。”大宝堆着一脸笑，说。 我看了眼大宝，心想你这马屁是拍到马腿上了，问：“什么疙瘩？” “还没想明白，”师父说，“明早再说。” 回到宾馆，我敲了敲隔壁房间的门。开门的是厅里的驾驶员，我往房间里瞥了一眼，看见了早已熟睡的林涛。 “这孩子估计是累坏了。”我笑着走进房间，摸了摸林涛的脑袋，“昨晚值班，今天又看了一天现场。看来他暂时是醒不过来了，也不知道他有没有什么发现。” 驾驶员也摇了摇头，说：“我也不知道，他回来就睡觉，澡都没洗。” “那明天，他岂不是要臭了？”我笑着和大宝回到了自己房间。 因为在DNA实验室外面睡了一觉，所以晚上我的精神很好。 我打开电脑，翻看着案件的照片，心里琢磨着，破案应该从哪里下手？如何刻画犯罪分子？侵害目标如果没有特定性的话，总是会为案件侦破加大难度。 “不过这样的案件也不少。”我心里暗暗鼓劲儿，“我们优秀的刑警总是能找出一些蛛丝马迹，顺利破案。” “我觉得这个案子必破，就是时间的问题。”大宝也在和我想着同样的问题，“我们有嫌疑人的DNA，大不了把村子里的男人都取样，不信找不到犯罪嫌疑人。” “是啊，”我点头说，“我们有DNA证据，有，不怕不破案，就是效率的问题。你看，网上都出消息了。” “老人少妇裸死家中，警方锁定犯罪嫌疑人。”斗大的标题在青乡市的网页上很显眼。 “估计记者们也以为孔威是嫌疑人。”我摇了摇头，说，“消息不算太灵通。这也是逼着我们尽快破案啊。” 第二天清早，师父打电话喊我们起床，驱车赶赴现场。车上，师父告诉我们侦查员对孔威的询问结束了，并简单把询问得知的情况告知我们。 孔威被捕的时候，面露惊慌和不解，从侦查员的经验来看，他确实不像杀人凶手。当孔威得知自己的妻子已经死亡后，先是惊愕，再是号啕大哭。同时失去父亲和妻子的他，整整哭了一个小时，才勉强稳定住情绪，开始诉说案发当天的过程。 案发当天上午七点，孔威就接到了小蔡的电话。小蔡的声音里充满了惊恐，结结巴巴表达出的意思就是早晨发现孔威的父亲没气儿了，身体都硬了。 孔威从小是被父亲拉扯大的，一听到这个消息，怀疑是小蔡没有照顾好父亲，或是故意害死了父亲，于是要求小蔡不准动尸体，老老实实待在家里，自己立即买了火车票赶回青乡。 孔威回到青乡，已经是晚上九点钟了。在父亲的尸体旁恸哭了一会儿后，孔威就注意到了床头柜上的注射器。他认为很有可能是小蔡故意害死了自己的父亲，于是，就上去打了小蔡两个耳光。但这次小蔡的反应非常激烈，称半年以来，自己尽心尽力照顾老孔，到头来却要担上这么个责任，甚至扯断了电话线，拿电话砸坏了空调。看到小蔡的激烈反应，孔威顿时觉得心虚，但是怒气依旧无法平息，于是摔门而出。到附近网吧对付了一夜，想明白了小蔡可能真是冤枉的。于是今天一天他都在市区的殡仪服务商那里咨询殡仪事宜。 “孔威今天一天都在到处咨询殡仪事宜。”师父说，“这个都查实了。” “那他摔门走的时候，门关好了没？”我问。 “孔威自称是记不清了。”师父说。 “看来，又被我们推断中了。”我说，“还真的应该是有人溜门入室。” 复勘现场是法医的一项重要工作，就像是答题答不上来，过一段时间再看，可能问题就迎刃而解了。 到现场后，我发现林涛和青乡市公安局的痕检员们早已在现场。 “这小子昨晚是睡好了。”我笑着向围在现场东侧卧室床边的痕检员们走去。 林涛神采奕奕地拿着一个多波段光源，往床上照射。 “有发现吗？”我问。 林涛点点头，说：“有的。你先看看女死者穿的鞋子。” 我低头望去，床边地上整齐地放着一双女式凉鞋。凉鞋的鞋底和侧面沾有淡淡的黄色泥巴。 “这鞋子怎么了？”我问，“案发前一天下雨了，她在院子里的菜地上劳作的话，肯定会沾有泥巴。” “再结合床上的痕迹看。”林涛指了指床上的凉席中央。 师父也凑过头来看，说：“不用特殊光源看还真看不到，这是蹬擦痕迹吧？” 林涛说：“是的，昨晚就发现了，但不确定，早上又来仔细看了看，而且取材回去显微比对。可以肯定这是蹬擦痕迹，而且是这双女式凉鞋所留。” “如果这样，”师父脸上洋溢出自信的微笑，“我心里的疙瘩就解开一半了。” “究竟是什么疙瘩？”我的好奇心又被师父吊了起来。 师父戴上手套，从物证箱中拿出小蔡生前穿着的衣服。一条白色的睡衣模样的连衣裙和一条白色短裤，都已经被完全撕碎了。 “床上有小蔡穿鞋蹬踏的痕迹，对吧？”师父说。 I said yes." 师父说：“说明了什么？” 我想了一下，说：“我知道了，您说的是，小蔡被侵犯的时候，是穿着鞋的。” “对啊，”师父说，“她是穿着鞋被按在床上遭受了侵犯，但是为什么鞋子会整齐地摆放在床边呢？” “凶手为了脱她衣服，所以脱了她的鞋子？”我说。 “你觉得衣服已经被撕成了这样，还需要脱鞋子吗？”师父抖开已经被完全撕裂的衣服说。 我点了点头，说：“是啊，即便是没有撕碎衣物，脱这样的衣服也不需要脱鞋子。” “你对脱衣服很有研究啊。”大宝在一旁调侃。 师父瞪了大宝一眼，说：“严肃点儿。既然不需要脱鞋子就能完成整个强奸、杀人的过程，那么凶手为什么还要脱死者的鞋子？” “是啊，关键是死者身上的抵抗伤并不太多。”我拿起凉鞋看了看说，“这种老式的鞋子直接脱还不太好脱，鞋子的扣襻是打开的。说明凶手是先解开鞋子扣襻，再脱下死者的鞋子。如果这样，凶手就没有其余的手去控制死者。” “凶手脱鞋的时候，死者已经丧失了抵抗能力。”大宝说。 我点点头，说：“强奸造成的损伤是有明显生活反应的，这说明凶手是完成了强奸、杀人行为以后，才去脱死者的鞋子的，这确实是一个比较奇怪的多余动作。” “所以我说疙瘩只解开了一半。”师父说，“去殡仪馆，复检尸体。” 车上，我忍不住问师父：“我们检验尸体的时候，并没有在死者的脚上发现什么痕迹、损伤啊。而且昨天晚上我还仔细看了照片，死者的脚并没有什么异常。” “别急，”师父摆了摆手，“如果是轻微损伤，可能并不那么容易被发现。但是尸体经过冷冻以后，会有显现损伤的作用。” 我点头认可。确实在很多案例中，都是通过冷冻，发现了尸体上原先并没有被发现的损伤。在《中国法医学杂志》上也曾刊登过《利用冷冻显现尸体损伤》的论文。 一路无语，我们很快来到了殡仪馆停尸间。 在满耳的冰箱压缩机轰鸣声中，我们找到了停放小蔡的尸柜。尸体刚被拉出来，我们都同时注意到了小蔡脚趾部位的损伤。 “居然真的有损伤！”我惊讶地喊道。 “第一次尸检，我们就该发现的。”师父戴上手套，用止血钳刮擦着损伤位置，“有轻微的表皮剥脱，可是初次尸检时因为和周边皮肤颜色一致，所以没有能够发现。” 我用止血钳夹起一个酒精棉球擦拭着损伤部位，几处微小的表皮剥脱逐渐显现出来。 “这是濒死期的损伤啊。”我说，“有表皮剥脱，但是没有明显的出血迹象，只有极其轻微的皮下出血，属于。” “那就说明我们推断正确了。”师父说，“小蔡在被扼颈窒息死亡后，机体细胞仍处于短暂的存活期。凶手就在这个时候脱下小蔡的鞋子，在她的脚上形成了这样的损伤。你们看看，致伤工具是什么？” “多处损伤整齐排列，单个损伤长不足零点五厘米，宽不足一毫米。”我的脊梁突然凉了一下，“是牙印！” “强奸杀人以后，咬她的脚？”大宝瞪大了眼睛。 “没见过吧？”师父说，“我也很少见到，是恋足癖。” “可是我听说，恋足癖是只对脚有兴趣，对其他部位没兴趣的。”我说，“这个案子有强奸行为啊。” “你说得对。”师父说，“不过性倒错心理因为个体差异而多种多样，有的恋足癖也会和别人发生性行为，有的恋童癖、恋尸癖也会和正常人发生性行为。这一种恋足癖，在强奸后并不能完全得到性满足，而要通过恋足来继续获得性快感。” 师父顿了顿，转头对林涛说：“我看这个损伤有条件提取牙模，和DNA一样能作为证据使用。” 林涛点了点头，转身拿出电话通知市局痕检同志携带提取牙模的工具尽快到殡仪馆来。 专案组里，师父公布了我们之前的所有工作，并圈定了侦查范围：“显而易见，这是一起溜门入室实施强奸杀人的案件。凶手应该是一名性心理变态患者，更详细地说，是一名恋足癖患者。这样的人，平时会喜欢看别人的脚，喜欢别人的袜子，甚至希望别人来踩踏他。至于侦查范围，应该圈定在附近村落。” “为什么不是本村的人所为？”刘支队问出了我的心声。 “要说依据，不是很充足。”师父说，“可能是直觉吧。我觉得如果是本村的人，想实施强奸，总会找到机会，比如白天小蔡出门、回家的时候。如果是外村人，过多在本村停留，就会引起村民的注意，那么他就只会在夜间寻找机会。我们知道，小蔡为人谨慎，夜里都是紧锁门窗的。相对于因为孔威的一次疏忽，凑巧就被犯罪分子抓住机会的观点，我更愿意相信是凶手晚上经常在现场附近徘徊，才抓住了这个机会。” “那好吧，”刘支队说，“重点查邻村、夜间会经过现场或是经常在现场附近徘徊的，可能有恋足癖的青壮年男性。同时小部分警力查本村的人。有了恋足癖这个线索，我相信我们的命中率会很高的。有DNA作为证据，不怕没有办法甄别犯罪嫌疑人。” “我有个线索。”一名辖区派出所民警举手说。 “说。”师父眼里闪烁着希望的光芒。 “我们所半年前处理过一个小孩，是案发现场隔壁村的。”民警说，“因为有人抓住他在偷女性内衣，被当作色狼扭送到我们派出所的。当时我还在奇怪，缴获的赃物里，除了女人的内衣，还有袜子。” “小孩？有多小？”师父问。 “十五岁。” “不太可能吧？”刘支队说，“现在小孩都这么早熟？” 师父看了刘支队一眼说：“怎么不可能，如果不计划生育，三十岁当爷爷也很正常。十五岁，完全可以具备性能力。” “我觉得很有可能。”我说，“死者身上的约束伤不重，甚至凉席上还有大面积的蹬擦痕迹，说明凶手的约束能力有限。如果是身强力壮的男人，约束伤会重很多。” “看来，这个小孩不仅有恋足癖，还有恋物癖啊。”师父默认了我的观点，“这个孩子什么情况？有晚上出门的条件吗？” “有。”民警说，“从小父母都不在身边，爷爷奶奶带大的。奶奶前两年死了，爷爷也没能力管他，天天逃课，在外游荡。” “抓人！”刘支队重重拍了一下桌子。 师父带着我、大宝和林涛一起坐在审讯室隔壁的监控室里，看着电脑屏幕里那个正在接受审讯的眉清目秀的男孩。 因为DNA和牙模都比对无误，侦查员有了信心。没过几个回合，在侦查员步步紧逼的攻势下，男孩就败下阵来。 “我没想杀死她。”男孩在抽泣，“我一直喜欢她，喜欢了好久，可是她不认识我。” “你怎么会喜欢她？”侦查员说，“你经常见到她吗？” “这几个月来，我一想她，就会爬墙头翻到她家院子里，隔着防盗窗，从窗帘缝里看她，她的脚好美，真的好美。” 师父看了眼林涛，林涛会意：“如果在墙头找到他的痕迹物证，就更是铁案了，我现在就去翻墙头。”说完，林涛拎着箱子走了。 “说一说那天晚上的
