Chapter 6 Case 4 Foggy Basement

The weather is gloomy, and so is my mood. This business trip, it can be said that I really want to go home.In the past, I always thought that I was a career-oriented man who put work first in everything, so I neglected to take care of my family.After having Xiao Xiaoqin, I found that I was gradually transforming into a family man.Every time on a business trip, once overnight, Xiao Qin's cute face would repeatedly appear in his mind, and his thoughts would come to his heart. But I know that in our line of work, it is very important to concentrate, so I forced myself to temporarily put down my thoughts.It is inevitable to handle the case overnight. Sometimes it takes several days to go on a business trip. After returning to Longfan, I often work overtime, so I have very little time at home, and even less time to communicate with Xiao Xiaoqin.

When I came back from a business trip this time, I was wearing a uniform and wanted to hug Xiao Qin, but he refused, and he even cried in fear.Maybe in his mind, I was a strangely dressed "stranger". Throughout the night, my mind was filled with little Qin's frightened face, and I could only wait until he was fast asleep, sitting by the cradle and quietly looking at his little face. Because Xiao Xiaoqin rejected me, I felt extremely guilty.I am an incompetent father, an incompetent husband, and an incompetent son and grandson.This reminded me that my grandfather who loved me the most was unable to be by his side when he was dying.At that time, my grandfather was intubated because of cor pulmonale, and he was unable to speak, and his mind fluctuated from good to bad.I originally asked for leave to stay with my grandfather in my hometown hospital, but I was entangled because I received a call about the case.Grandpa was still very sober at the time, and he wrote the four words "National affairs are the most important" in the palm of my hand.After crying and kissing my grandfather on the forehead, I rushed to the crime scene.But unexpectedly, that kiss was actually a farewell.

It is even more uncomfortable for my son to treat himself as a stranger. The next day, while secretly making up my mind to spend as much time as possible with my son, I walked into the gate of the Public Security Bureau in a depressed mood. I've often said that I'm an adaptable person, changing how I feel as circumstances change.For example, at the carrion scene, I would feel very sick at first, but after a few minutes, as long as I concentrate on the autopsy, I will slowly get used to the stench and unbearable smell. So, when I walked into the office with a gloomy face and found that everyone was laughing and fighting, my mood was instantly filled with sunshine again.

"You guys, you have so many secrets!" Lin Tao said to Han Liang, "Which ex-girlfriend's hobby is "Snake"?" "Don't talk nonsense." Han Liang said sternly, and then he hesitated to speak again. "Then talk about the doctor's daughter, Yu Yingying, right?" Chen Shiyu pretended to be casual and joked, "Did you go to comfort her later?" Han Liang was dragged away by Chen Shiyu from the topic he didn't want to talk about, feeling very relaxed, so he said with a smirk, "That's necessary. I'm a warm man after all. It's my duty to comfort people."

"Bah! Fart warm man!" Chen Shiyu blushed. "Hey, you are a little girl, how can you swear." Han Liang said. "I learned from you!" Lin Tao interrupted. "Okay, you can't chat during working hours." I stopped their conversation with a smile, "Little Feather, is there any progress on Duzhou's matter?" Chen Shiyu shook his head and said, "Not yet. After all, the brothers and classmates are usually busy with work, so I can only use some spare time to search, so there are no clues yet." I nodded to show I understood, put the bag on the desk, looked left and right, and said, "Isn't Dabao here yet?"

"No, he took a public leave. He should be searching the area around Duzhou's disappearance." Lin Tao said, "This guy is really caring. To us, the public leave is so precious! There are only a few days in a year." .” "After all, he is his brother who has played with him since he was a child." I said, "Although I hurt him severely once, it is not so easy to let go of my childhood feelings." In our survey team, it only takes a second to switch from chat mode to work mode.After the chat was terminated, everyone began to work hard, and each completed the material tasks that they needed to complete.

Until a phone ringing broke the silence of the office. I looked up and saw that it was not the command call from the command center, so I was relieved for the time being.The caller was looking for Chen Shiyu. After Chen Shiyu answered the phone, he answered a few words briefly, raised his eyes and said to us: "In the area where Du Zhou disappeared, some bloodstains were found. I wonder if we can go over and give some guidance. " Hearing the word "bloodstain", my head buzzed instantly.Qu Xiaorong said that she once had a bad feeling.Although this premonition has no factual basis, her words have been lingering in my ears.I don't know why, although I have only met this Duzhou once, and I still hate him, but I am still very worried about his safety.Maybe it's because I've been with Dabao for a long time, so I feel a little empathy.Qu Xiaorong is pregnant at this time and is still living in Dabao's house. If something happens to Du Zhou, I don't know what will happen next.The happy life of Dabao and Baosao has just begun, and it is not an easy beginning, and there must be no mistakes.However, if anything happens to Duzhou, will the kind Dabao and Baosao sit idly by Qu Xiaorong?

But the thought was fleeting.We know that the city is so big, there are too many traces of blood, such as paint, paint, juice and so on.Moreover, even if it is really blood, it may be animal blood.At the murder scene, we often screen whether the suspected bloodstains are related to the crime, mainly to conduct confirmatory experiments and species experiments on the bloodstains. Because the conditions for the public security organ to file a case for investigation are: 1. There are criminal facts.That is to say, in a case that has been accepted, the behavior of the criminal suspect has violated the criminal law and constituted a crime.This kind of criminal fact has existed objectively and is not a subjective conjecture; it has been proved by evidence and is not groundless.

2. Criminal responsibility needs to be investigated.That is, the criminal suspect's criminal behavior needs to be punished according to law.If his behavior only constitutes a crime and should not be investigated for criminal responsibility according to law, the case should not be filed. 3. It belongs to its own jurisdiction.Public security organs can only have jurisdiction over cases that are under their own jurisdiction as stipulated by the law. Those that should be governed must be handled, regardless of dereliction of duty; Therefore, even if something resembling blood is found within the range where Du Zhou disappeared, it may not be very meaningful.Even if we are sure that it is Du Zhou's blood, it can only provide us with a direction for our next search, but not necessarily allow the public security organs to file a case for investigation.

But no matter what, it's better to have a discovery than to disappear, and this also confirms that Xiaoyu's appeal among her classmates and senior brothers is still very strong. While we were packing our things, several people squeezed into Han Liang's small Audi TT and rushed to the scene. At the same time, we called to inform Dabao that he was also rushing to the scene.After all, Dabao is more familiar with Duzhou, so he might have an unexpected viewpoint. Along the way, we were all complaining about why Han Liang, a big man with a height of 180 centimeters, bought such a small car, which made it difficult for the four of us to sit down.Han Liang looked aggrieved, saying that he had to be scolded for using his own car for public use.

After all, it was not the scene of a criminal case, so there was not such a big fight.But in the distance, we heard the cry and felt puzzled.When he got closer, he found that Qu Xiaorong was sitting on the ground crying, and Dabao was squatting one meter away from her, talking to her, and beside him was a young policeman in uniform. I was a little dissatisfied with Dabao, so I approached him and pulled him aside, and said, "Dabao, why did you bring her here directly? There's nothing to explain here, and the horoscope hasn't been written yet." Dabao looked aggrieved and said, "These two days of vacation were requested by Menghan. She asked me to spare time to accompany Qu Xiaorong to find Duzhou. So when you called, we happened to be nearby." I spread my hands helplessly, walked to the side of the "scene", nodded gratefully to the young policeman, and then squatted on the ground to observe the suspicious place discovered by the police. "What kind of place is this?" Lin Tao stood beside me, observing the surrounding environment. "It's already two kilometers away from the bus station." The policeman said, "It's a remote place, but there are a lot of demolition households living nearby, so it's not particularly remote. A hundred meters further to the east, you'll find the immortal Mountain." I know that although Shenxian Mountain can be regarded as a park, because of the dense vegetation and lack of management, no citizens really regard it as a park.The park is open, anyone can enter, and there are no guards and surveillance, but usually there are few people.There are very few homicides here, but quite a few people commit suicide here. "So this alleyway is usually very remote?" I just finished asking when two people passed me on a moped and looked at us curiously. "It's not too remote." The policeman laughed dumbly. "It's hard to say. It's the only way for many people to go to and from get off work, but there are also many times when no one passes by." I nodded and looked at the "pool of blood" discovered by the police. This pool of "blood stains" has dried up, and the area is about 20 square centimeters.I opened the investigation box, took a little "blood" with a cotton swab, tested it with the benzidine test, and it was positive. "It's blood." I said, "Take some and send it to Sister Zheng for a DNA test." Hearing what I said, Qu Xiaorong cried louder again. "However, even with the DNA data, how can we be sure that it is Du Zhou's? Do you have Du Zhou's DNA sample?" I looked at Dabao and Qu Xiaorong. Qu Xiaorong seemed not to have heard my question, and continued to cry, while Dabao shook his head blankly. "Don't cry." I was a little impatient, "First of all, I can't be sure if it's human blood, maybe someone killed chickens and ducks here! Secondly, even if it's human blood, I can't be sure if it's Du Zhou's. Finally , even if it is Du Zhou's blood, such a small amount of bleeding will not cause death! Why are you crying?" Hearing what I said, Qu Xiaorong seemed to be comforted, and sobbed and said, "When I came here just now, I saw a shoe next to the blood, and that was Du Zhou's shoe. So...so, the blood must be It's Du Zhou's! There should be Du Zhou's DNA in the shoes, right? Teacher Qin, with so much blood, is it really... really not dead?" I was shocked that this weak woman actually has the knowledge of biological testing, and knows that DNA data can be made in shoes.However, I changed my mind. After all, Qu Xiaorong has been with Dabao for so long, from Dabao's student stage to working stage, so it is normal for her to acquire this kind of knowledge by ear. Since a shoe of Du Zhou was also extracted at the scene, it is more likely that the pool of blood is Du Zhou.Or, Du Zhou hurt someone else. "Without filing a case, can we do an inspection?" Chen Shiyu asked. I shook my head and said, "However, the results can be produced first, and the appraisal report will not be issued. At least it will have a clear direction for our search." After speaking, I looked around the pool of blood carefully.As I expected, this bloodstain did not exist in isolation.On the wall not far from the pool of blood, there seemed to be some splattered blood.The height of the bloodstain is at the height of a person.According to my impression of Du Zhou, if the blood was really sprayed from his body, it should be on his head.My heart was pounding in my heart: If other parts of the body were damaged and there was so much blood, it would not be fatal.But if it was a head injury and shed so much blood, it might not be so.After all, the fatality rate of traumatic brain injury is still quite high. However, I soon became more at ease. Because Lin Tao found some gauze in the garbage next to the pool of blood, and some of the gauze was even stained with blood.If someone bandaged him after the injury, it means that Du Zhou was not life-threatening at the time of the injury and he was healed.So from the discovery of blood to the discovery of gauze, it can be said that the prediction has changed significantly. After investigating for a while, it was determined that there were no other suspicious items in this area, so we decided to close the team. "Several bloodstains and gauze, as well as Du Zhou's shoes discovered by Qu Xiaorong, will be sent to the DNA room for inspection and comparison." I said, "It's a pity that there is no case filed now, and police resources cannot be mobilized. Otherwise, the inside of Shenxianshan Park , and search around Shenxian Mountain, or investigate the 120 police dispatch records and nearby hospitals, it is very likely that we will find clues to Duzhou." "Only these two scopes of investigation?" Chen Shiyu asked. I nodded and said, "With the current situation, we can only define these two scopes. However, even if there are only two scopes, the workload is huge." Chen Shiyu nodded and turned to look at the young policeman. "Elder Sister! We are the only people who have to go to work..." The policeman wanted to evade. Chen Shiyu stared. "Okay, okay, okay, let's look for it." The policeman looked helpless. I laughed, thinking that this Chen Shiyu actually has the title of "Master Sister" in school, and she is so domineering.However, this strong and domineering energy has a very good effect at this time. Job done, little progress, but we can only close the team. Dabao drove Qu Xiaorong back home on his small motorcycle, while we continued to squeeze into Han Liang's TT and drove towards the Public Security Bureau. When Han Liang turned a corner, he suddenly heard a whistling sound, and a familiar blue and white shadow flashed in front of his eyes, gliding towards our side. "It's the crime scene investigation vehicle of the Technical Brigade of the Criminal Police Detachment of the Longpan City Bureau." Lin Tao responded the fastest. "Generally, the alarm will not be raised at the theft scene that needs to be investigated." I said, "Since the alarm was raised and he ran so fast, he must be dead." "My God." Chen Shiyu said, "Where did Conan go to kill people, and this survey vehicle has the same problem." "Would you like to follow up and take a look?" Lin Tao seemed to be possessed by a big treasure at this time, and he almost shouted "I am out of the survey site, and I don't have hemorrhoids". "It's ok, anyway, we have already reported to Master about the morning's actions." I looked at my watch and said. Without further ado, Han Liang slammed the steering wheel, and TT turned the car around in a beautiful arc, chasing after the survey vehicle ahead.Soon, our car followed the survey vehicle. "Now you know why I bought such a small car because I am so tall." Han Liang grinned and said, "The driving performance is really good!" "The next time you show your driving skills, can you tell us in advance?" Because of the sharp turn, Lin Tao and I, who were sitting in the back row, almost hugged each other, I said angrily. "Shouldn't the blood-stained gauze and other test materials extracted just now be sent to Sister Zheng?" Lin Tao asked. "After a while, Han Liang sent us to the scene, so he hurried back to the hall to deliver the test materials, and asked Sister Zheng to deliver the results as quickly as possible." I said, "Come to the scene and wait for us after delivery." We followed the survey vehicle and soon arrived at a resettlement community. This resettlement community is located on the outskirts of Longpan City. It is a gathering place for residents who have moved back after demolition of a large industrial park in the Economic Development Zone of Longpan City.Because during the demolition, not only a resettlement house was supplied to the residents, but also a large amount of demolition funds were compensated.Therefore, almost all the residents here have bought houses in the city, and almost all of them have become rental houses. The houses in the community are large and small, and some tenants even rent other people's underground storage rooms to save money.The site surveyed by the Municipal Bureau is the underground storage room of a house in the community. When we got off Han Liang's car, Chief Hu was taken aback. "Oh, what's the matter?" Chief Hu said, "Why did this case alarm you?" I smiled slightly and said, "Don't be nervous. We saw your car and followed. Anyway, we don't have work this morning." "I said." Chief Hu said, "Although two people died, it is basically ruled out as a murder case, unless, of course, someone deliberately poisoned them." "Poisoned?" I said. "Poisoned?" "It's hard to say." Chief Hu said, "It was guessed by the police from the police station who went to the survey site in the early stage. You have also seen it, we just arrived." I nodded and said, "What basis does he have?" "The site is closed." Chief Hu said, "The renters are a family of three. The male is named Mao Ting, 40 years old, and works as a migrant worker in the city. The female is 38 years old, named Rong Dongmei, unemployed. The child is studying in the city. The child is Mao Yuanda. He is thirteen years old and is in the first grade of junior high school. He is studying in No. 102 Middle School not far from here. The boy is introverted by nature, so there is no conflict. " "Have you investigated the situation before the incident?" I asked. "When I was in the car just now, I heard a little from the investigation department." Chief Hu said, "Last night at 8:00, Mao Ting came home from get off work. At 7:00 this morning, his coworkers came to the basement to ask him to go to work together." , No one opened the door after knocking on the door for a long time, so I looked around the window and found that the whole family was lying on the ground, so I kicked the door and entered. Later, the nearby residents called 120 for help. Mao Ting was still breathing weakly. The hospital, both mother and child died. There was vomit on the ground." "There are still windows in the underground storage room?" I also looked around to the other side of the building. "This underground storage room is not really underground, but it is lower than the ground level." Chief Hu said, "So half of the windows are above the ground level. It looks like a prison in the past. Only the top of the wall is open." There is the half window. For safety, there are anti-theft windows on the outside of the window, and no one else can get in. When the incident happened, a 5 cm wide gap was opened in the window at the scene. Before we came, the trace inspection department had checked, The windows are normal." As soon as the words fell, Cheng Ziyan came out of the underground storage room with the investigation box in hand. After seeing Lin Tao, his face blushed slightly, and he whispered, "Hello, Chief Lin." She paused, then said, "Hello, Section Chief Qin." I nodded slightly and said, "How's it going inside?" Cheng Ziyan said: "After reading the traces on the ground, except for the footprints of more than 120 doctors and nurses, there are only footprints of this family of three. We have sufficient grounds to rule out that other people have entered the scene. Of course, their house looks normal. No one else came either." "That's right, living here, I'm really embarrassed to invite others." Lin Tao said, "It's a bit scary to come in at night." "No matter how you get in, you're scared everywhere?" Chen Shiyu said. "How do you know it's not scary at night?" Cheng Ziyan looked around and replied softly. I waved my hand and said, "Let's go in and have a look." The scene was not as scary as Lin Tao said. Walking into the underground aisle, the aisle was filled with some daily necessities, which almost became the storage room of the tenants here, and it seemed to be full of life. The scene is at the end of the underground storage room. This small living room is actually composed of two storage rooms.It may be that the landlord was allocated two storage rooms when he moved back, so he built the door of one with bricks, and then opened up the two storage rooms and rented them out together. Two storage rooms are combined into a small suite, each about fifteen square meters in size.Because it is an underground storage room, and each storage room only has half a window leading to the outside, it is extremely dark even in broad daylight. According to the reporter's description, at 7 o'clock in the morning, when it was daylight, the two overhead lights at the scene were turned on, so the reporter could have a panoramic view of the whole house from outside the window. The ground at the scene had obviously been cleaned up by Cheng Ziyan and the others, and no traces of other people were found.When the reporter found out, the gates of the scene were locked, so it was considered a closed scene.Since it is a closed site, the probability of accidents is much higher. Even if it is not an accident, it should be self-produced and sold. Therefore, such a scene will make the forensic doctor a lot easier.Instead of using the prospecting pedals, we put on shoe covers and went straight to the site. In order to make the two underground storage rooms look like living places, the landlord specially decorated them.In addition to the floor tiles with good carrier conditions, the walls are also covered with tiles to ensure that the walls of the storage room will not be moldy.The roof is also decorated with cheap suspended ceilings, so it seems that the indoor environment is not bad. In the storage room leading from the entrance there was a bed and a dining table with some chairs.Judging from the color of the quilt cover on the bed, this should be the place where the husband and wife usually live.In the storage room in the inner room, a glass door is used to divide the storage room into two parts.A small bed is placed in the part next to the passages of the two storage rooms, while the other part inside is equally divided into two parts by glass partitions. The half near the wall with windows is a small kitchen, while the other half is a small kitchen. It's a bathroom plus toilet. The kitchen and bathroom share a glass sliding door.If the door is pulled to the bathroom when taking a bath, the kitchen is open to the outside; if the bathroom door is opened after taking a shower, the glass door closes the passage to the kitchen. The window leading to the outside world is divided into two by glass, one part is the kitchen leading to the outside world, and the other part is the child's bedroom leading to the outside world.There are dense anti-theft nets on the outside of the windows at the scene, but the aluminum alloy sliding windows are opened nearly five centimeters on both sides to ensure ventilation. After all, the weather is not very cold anymore. I looked around inside and out, and found that this is a basement after all. Even though some window slits were opened, the room still maintained a very high degree of closure.Because some water droplets attached to the walls can be seen on the surrounding tile walls, this is caused by insufficient ventilation so that the air moisture is not evaporated.It is conceivable that the air humidity in the room is very high. The mother and son of the deceased were lying on the edge of the bed in the inner room, with some vomit around their heads.The situation at the scene was as simple as that. There was no obvious injury on the body of the deceased, and there was no trace of disturbance at the scene.Of course, in such a scene, there is no money and it is not easy to steal, and thieves will not come. If there is any doubt, the only thing is that the dead woman was completely naked. Mao Ting was discovered outside.On the dining table outside were some dishes, some sets of bowls and chopsticks, as well as a bottle of white wine and a wine glass.There was also a puddle of vomit at the foot of the table.According to Comrade 120's notes, Mao Ting fell beside the dining table, unconscious.It seemed that he fell to the ground suddenly while he was eating.According to Doctor 120, Mao Ting's vital signs are very unstable, and it is still uncertain whether his life can be saved. "It looks like an accident," I said. "Everyone was vomiting. Food poisoning cannot be ruled out." I asked Forensic Doctor Han to take several evidence bags and extract all the leftover food, wine and tableware on the table. "Could it be carbon monoxide poisoning?" Lin Tao walked into the kitchen and carefully looked at the water heater hanging on the wall. "The water heater is connected to the canned liquefied petroleum gas." Cheng Ziyan said, "The old-fashioned gas is no longer used. Moreover, this family has lived here for almost two years. Unless the water heater suddenly fails, it will not be said that it was fine before. There's something going on now." "And the corpse spots do not have the characteristics of cherry red." Chief Hu said, "Because carboxyhemoglobin is cherry red, so in the case of carbon monoxide poisoning, the corpse spots are more characteristic of cherry red." I nodded and said, "That's not entirely absolute." After speaking, I also walked to Lin Tao's side and looked at the water heater. The water heater is very new, it should have been newly installed when the family moved in two years ago.The water heater adopts the model of a wall row, and a large pipe with a diameter of 20 centimeters is connected to the hole on the wall to discharge the generated exhaust gas outside the house.This should be a pretty safe way to use your water heater.Moreover, beside the water heater, there is a white probe that says carbon monoxide detector.It seems that this water heater is a new model, with a function that can detect carbon monoxide and alarm when it exceeds the standard. I moved a stool to the kitchen and stood on it to take a closer look at the detector.There is a line of words printed on the detector: When the carbon monoxide exceeds the standard, the detector will keep beeping and the red light will be on. Apparently, it didn't call the police. I jumped off the bench and said, "It looks like food poisoning is more likely." Chief Hu nodded, turned to the investigator outside the house and said: "According to the trace inspection, there is no sign of outsider intrusion. The deceased did not have any signs of injury. However, since food poisoning is considered, it is recommended to dissect and extract the stomach contents And the liver will be tested together with the food extracted from the scene. In addition, you are now focusing on investigating the source of the food of the deceased. If poisoning can be ruled out, it should be an accident." "Hopefully the injured man will come back," I said. "If he regains consciousness, it will help us figure it out." Coming out of the scene, it was almost noon. "We're going for an autopsy, are you still going?" Chief Hu asked us with a smile. I looked at my watch and said, "Participating in the autopsy now may delay the afternoon shift. We came here on our own without receiving instructions. It's better not to delay work." "Okay." Chief Hu laughed and said, "Looking at the current situation, it can basically be ruled out as a murder case, and it's just an ordinary abnormal death." "There are hundreds of such abnormal deaths a year, you have worked hard enough." I said. After we broke up, we walked out of the scene.Han Liang had already parked his TT outside the community.We squeezed in again. Han Liang seemed to be playing "Snake" in the car just now. "Just watched the scene and the body, don't you mind getting in your car?" I said jokingly. "Do I seem to be such a fastidious person?" Han Liang said while putting his old mobile phone into the inner pocket of his clothes while fastening his seat belt. "It's not like." Lin Tao watched him pick up his old mobile phone with a playful smile, and said, "But he looks like a nostalgic person." Embarrassed, Han Liang pressed the button to start the car. With the roar of the car engine, my mobile phone and Chen Shiyu's mobile phone rang at the same time. "No, where we found the bloodstain, we found a body on the mountain behind!" After answering the phone, Chen Shiyu said, "My classmate is on vacation today. He just found a few friends and cast a net near the bloodstain to look for it. , and found another case." "News came from the DNA room that the blood on the floor, walls and gauze belonged to Du Zhou." I was a little anxious, "Can your classmate be sure that the body found is not Du Zhou?" Chen Shiyu shook his head and said, "The deceased is a woman." Han Liang stepped on the brakes, looked back at me, and waited for my decision. I sat in the back seat, bit my lip and thought about it, and said, "Come on, although we may not have much contact, let's go and check the specific situation, just in case. Master, I'm calling to ask for leave. Also, did your classmate call the police?" We followed the road just now, returned to the scene where the blood was found, and then walked through the alleyway to the gate of Shenxianshan Park. The Municipal Bureau's investigation team B had obviously been dispatched, and another on-site investigation vehicle had already parked at the gate of the park. When I walked to the foot of Shenxian Mountain, I seemed to smell a rancid smell.It was still early spring, and highly decomposed corpses were uncommon.But because of years of forensic work, I am very sensitive to rancid smell.So, I was at the foot of the mountain, and I could almost tell that what we were about to face would be a corrupted corpse. Dabao, who arrived later, did not bring Qu Xiaorong with him. Hearing that the deceased was a woman, he felt relieved.We are all praying that this case has nothing to do with Du Zhou's disappearance.After all, once there is a relationship, Du Zhou may be the next victim, or Du Zhou may be the murderer. On the mountainside of Shenxian Mountain, a cordon was pulled up, and many policemen stood around.The vegetation here is dense, and it seems that it is usually inaccessible.Because of the obstruction of the bushes, the policemen stood crookedly. Chen Shiyu's classmate had already removed the single police equipment. He was wearing a police uniform and standing in the bushes with a German shepherd dog on his lead. He was questioned by the police as a reporter. This kind of situation where the police question the police is rare, so I walked aside to listen with great interest. "Hey, are you using a police dog for private affairs?" Chen Shiyu was very surprised, squatting next to the German Shepherd to tease it. "This is my own dog." The classmate was surprised when he saw the policeman receiving the police, and quickly explained, "I learned the technology of police dogs, but I was assigned to work in the police station, so I had to raise one myself to enjoy myself." "The earth dog can also help you find clues?" Chen Shiyu covered his mouth and smiled. The German Shepherd seemed to understand Chen Shiyu's sarcasm, and turned his head away from her. The classmate looked helpless: "Who said it was a native dog? This dog was carefully trained by me. He dared to compete with any dog ​​in the police dog base." "Did it find it?" I asked. The classmate nodded and said, "I found the pool of blood when I got off the night shift in the morning. The senior sister said she was going to look for it around, but I couldn't find help for a while, so I led it out. It ended up running all the way. , and found it directly here.” I turned my head and saw the forensic doctor of the Municipal Bureau’s investigation group B, who was examining the corpse, and said, “Does anyone come here often?” "Almost none," said the policeman in the area. "This park is not well maintained, and very few people come. Even if people come, they will enjoy the shade and chat in the square at the foot of the mountain. Few people will climb the mountain." "Are there any traces at the scene? Import and export or something." I asked the trace inspector. The trace inspector shook his head, pointed to the ground and said: "There are no roads here, the weather is dry, and the soil can't leave any footprints. We looked at the surrounding bushes, and there were indeed signs of breaking. But we can't be sure that the deceased walked over and broke them." Yes, it was broken when someone dumped the body here. So, it doesn’t make any sense.” I nodded, walked into the center scene, and asked the forensic doctor Dan who was concentrating on his work: "Brother Dan, how does the body look like?" Needless to say, but according to the forensic doctor, I have already been suffocated by the rancid smell.The whole body of the corpse was swollen, the surface was dark green, and a lot of putrid liquid flowed out.The face of the corpse was covered by messy long hair, and because of the infiltration of the putrid liquid, the hair was firmly stuck to the face, making it impossible to see the face of the deceased clearly.You don't need to look to know that at this time, the eyeballs and tongue of the deceased must have been pushed out due to the effect of the corrupt gas.The body of the deceased should be very thin, but at this moment, it can only be seen that it is very swollen.Although the temperature is still relatively low at this time, there are already a small number of flies circling around.Under the corpse, there were still some unknown little bugs crawling around.Flies generally appear in an environment of eight to forty degrees Celsius, and now the air temperature is more than ten degrees Celsius.However, due to the unstable temperature, the number of flies was small, and no large number of maggots were found attached to the corpses, so it was impossible to judge the time of death based on the length of the maggots. "This season, the giant has already been watched." But the forensic doctor said, "It seems that he should have been dead for more than seven days." I nodded in agreement. "The corruption is still very strong." But the forensic doctor spit out a mouthful of sputum and said, "It stinks very much. But I probably checked the key parts and found no obvious damage." "Looking at his clothes, he looks like a homeless person or a mentally ill person." Lin Tao stood aside and said, frowning. The dead man's clothes had been completely soaked in the putrid liquid, crinkled and stuck to the corpse, showing a black-green, damp appearance.But we can still see that the clothes of the deceased are relatively complete, with no obvious tear marks. "The upper body of the deceased was a cotton sweater, an old sweater, and an old coat; the lower body was cotton boxer briefs, cotton wool pants, and a pair of old trousers. Barefoot, no socks and shoes." But the medical examiner said, "But all the clothes were worn It is neat. Moreover, I checked the inside of the underwear, and there is no mud sticking, which does not conform to the artificial clothes after being invaded in the wild. Generally speaking, the clothes are normal.” "No bra, and poor quality clothes," I said. "It's kind of homeless." "It's a pity that because of the corruption of the corpse, it is impossible to judge whether the previous clothes are clean." Lin Tao said, "If the clothes are not clean, we can be sure." "Is there no clue about the cause of death?" I asked. "Could it be starvation, cold death?" "There is no abnormal undressing phenomenon, and there is no evidence to show that he died of freezing." But the forensic doctor said, "It is not very cold now, and the deceased was still wearing so many clothes. However, whether he died of starvation after getting lost cannot be ruled out." "That is to say, it needs to be dissected further." I said. But the forensic doctor nodded and said, "Hey, by the way, why did you come here for such an abnormal death?" 我笑了笑，说：“我们最近在办一起失踪案件，在离这个现场不远处，有一摊血迹，是失踪人员的血迹。我们害怕这起案件和失踪案有着某种关系，所以过来看看。” “现在看起来，死者是个弱女子，身上也没有伤。”但法医说，“所以和失踪案有关的可能性不大了。” “下一步怎么办？”我问。 “尸体马上要拖回去解剖检验。”但法医说，“首先得搞清楚死者的死因。如果不是命案的话，就要把特征交给办案单位去找尸源了。看看失踪人员DNA库里有没有线索。” 我看了看手表，转头对我们小组其他几个人说：“反正假已经请了，不如一起去看看？” “必须的。”大宝说。 抵达龙番市公安局法医学尸体解剖室的时候，刚好看见胡科长他们勘查组检验完尸体在锁门。 “你们怎么又来了？”胡科长一脸茫然。 “又发生了一起未知名尸体死亡的事件。”但法医说。 “你们这是来我们市局体验生活吗？”胡科长笑着说。 我挠挠头，说：“邪了，最近事情连续发生，就没有停过。你们刚才的检验结果怎么样？” “简单的尸检。”胡科长说，“排除机械性外伤，排除机械性窒息，排除疾病和电击，现在基本肯定是中毒死亡了，就要看是什么中毒了。我们看了胃内容物，和现场呕吐物的成分吻合，和现场桌上的菜是吻合的，而且是用过晚餐后不久死亡的。” 对很多法医来说，腐败尸体未必就是最恶心的。有的时候，对胃内容物的分析，也是很难受的。毕竟要把胃内、肠子内的东西弄出来，然后一点一点地筛，最后根据食物形态来分析和现场的食品是不是同类。毕竟法医也是人，也要吃东西，难免会在吃相同菜品的时候，想到那恶心的胃内容物的状态。 “法医看胃内容物这活儿真恶心。”林涛像是看穿了我的心思，说。 大宝眨巴眨巴眼，说：“恶……恶心？没什么呀，看惯了就好了。上次我请你们吃野生老鳖，你们吃得不是挺快活吗？” “什么意思？”陈诗羽警觉地问。 “上次我喝多了，路过一个水库的时候，趴在水边就睡着了。”大宝说，“等我醒来的时候，发现我旁边趴着一个老鳖，于是我就提回家红烧了给你们吃了。不记得了？” “记得啊，然后呢？”林涛说。 大宝说：“哦，那是因为我当时喝多了，吐了，老鳖从水里跑出来吃了我吐的东西，然后它也醉了。不然，我怎么抓得住一个大王八！说明胃内容物有的时候还可以钓鱼，钓的还是甲鱼。” “我关心的是，我们吃了那只吃了你胃内容物的老鳖？”林涛瞪大了眼睛。 大宝故作无辜地点点头。 “你他妈也太恶心了！”林涛和陈诗羽一起去捶大宝。 “这里别闹。”我制止了他们，说，“胡科长你们赶紧去送检吧，出结果了也告诉我们一声。我们也要开始检验这具腐败尸体了。” 胡科长锁好门，点点头，说：“估计检验结果今天夜里能够出来。” 说完，胡科长一组人上车离开，而我们则留下来对山中的腐败女尸进行尸检。 因为腐败的关系，死者的衣物牢牢地粘在尸体的皮肤上。而死者的皮肤又因为腐败液体的渗透，变得容易脱落。所以我们去除了死者衣物以后，死者的表皮也就脱落得差不多了。 和尸表检验的结果一样，我们仔细检查了这具“绿巨人”，全身都没有找到明显的损伤。表皮是不是存在擦伤，则不得而知了。 我重点看了看死者的足底，因为死者是赤足的，如果足底干净则会是一个疑点。不过，此时腐败液体产生，死者的足底黏附了大量的泥土，究竟是生前行走时黏附还是死后黏附，已经不太好判断了。不过，死者的足底表皮并没有因为脱衣服而损坏，我小心翼翼地用纱布将死者的足底擦净。 因为腐败，死者的足底皮肤都已经皱巴巴的了，有没有损伤实在不太好判断。但是总体看上去，好像并没有老茧的普遍产生。 一个长期赤足行走的人，足底会没有老茧吗？现场灌木丛生、石子遍布，爬了一半的山，足底没有大的溃口可能吗？我的心里产生了一些疑问。但是毕竟尸体是高度腐败的，有可能导致征象的错误，所以仅凭这一点，并不能说明什么。 说不定，并不是一直赤足，而是走到半路才把鞋子走掉呢？ 现场附近有杜洲的血迹，还有杜洲的鞋子。鞋子，是不是这两者有什么关系呢？ 一时想不明白，还是从尸体解剖开始。 但法医和大宝一组，对尸体的胸腹腔进行解剖检验，而我则剃除死者的头发，对死者的颅腔进行检验。 剃下头发后，我把头发整理好，准备放进塑料袋。突然，窗口的一束阳光照了进来，我愣了一下。 “这头发，我怎么感觉好像染过？”我说，“好像是栗色的。” “不会吧？”大宝探头过来看。 大家都知道，如果是个流浪人员，染头发则不太好解释原因。 “没有啊。”大宝说。 “你鼻子那么好使，眼神咋就不行？”我把头发举起来，让阳光照射。 “我也看不出来。”林涛说。 “是我眼花吗？”我有些质疑自己的发现。 “不是眼花，是色盲。”但法医也帮腔道。 “好吧。”我把头发装好，说，“死因找到了吗？” 但法医摇摇头，说：“没有任何损伤的征象，虽然有窒息征象，但是口鼻腔和颈胸部并没有损伤痕迹，也不是机械性窒息死亡。胃里面虽然是空的，但是肠内是有明显食糜的。也就是说，死者是末次进餐后七八个小时死亡的。食糜我们也看了，毕竟已经消化到了肠道，基本辨别不清食物形态了。” 我突然想起大宝的老鳖，泛起一阵恶心。 “既然这样，显然也不是迷路后饿死。”我说，“那死因是什么呢？” 说话间，大宝已经用“掏舌头”的手法，把死者的食管、气管和肺脏拉了下来。因为腐败，内脏器官的结构都已经模糊不清了。 “病理又做不了，拉脏器做什么。”但法医说。 大宝则仔细分离了死者的喉部，说：“你们看看，死因应该在这里。” 顺着大宝的手指，我们看见死者的喉头部位被大宝分离得很干净。这里的软组织颜色明显比周围软组织颜色要深，而且因为肿胀，闪闪发亮。这里的肿胀不均匀，显然不是由腐败而导致的肿胀。基本可以确定，在死者死亡之前，喉头就已经水肿了。 死者喉头水肿的程度是比较罕见的，整个喉管都因为周围软组织肿胀而被堵塞了，会厌因为被挤压，微微翘起。如果不用手指去探查，甚至不知道死者的气管入口在哪里。 “喉头水肿吗？”我从大宝手中接过死者的喉头，问道。 大宝点点头，说：“我刚才在检验死者口腔的时候，就看见喉头部位好像有些反光。如果不是高度肿胀，从口腔里是看不到反光的。” 我点了点头，用手术刀切开死者的气管。气管因为是软骨，所以腐败的程度远远没有其他软组织那样快。死者气管内侧的形态还都是正常的。从气管的内壁，可以看到密密麻麻交错的毛细血管网。显然，这也不是腐败形成的，而是一种生活反应。 “死者的气管也是高度充血。”我说，“虽然进行组织病理学已经没有意义了，但是我们还是可以推断出，死者死于哮喘病引发的喉头水肿。” “死者有哮喘？”但法医问。 我说：“很有可能。” “如果有哮喘，还得不到治疗，她是怎么活到现在的。”大宝说。 我摇摇头，说：“我觉得只有一种可能，就是以前哮喘发作的程度并不严重，而这一次不知道是什么原因，发作程度加重，又得不到治疗，所以引发了喉头水肿而窒息死亡。” “又或是有人看护的精神病患者，在走失后迷路。”林涛说，“不巧的是，迷路了以后，又突然发病，没有得到及时救治。” “如果真是这样，倒是好事。”我点点头，说，“如果是有人看护的精神病患者，走失后肯定会报警，甚至录入DNA，那么找到尸源也就方便结案了。” “好在是死因找到了，而且是疾病死亡。”但法医松了一口气，说，“既然是疾病死亡，死者身上没有伤，会阴部也正常，没有遭受性侵的迹象，死者穿着又这么廉价，也不像是有侵财的事件发生，这应该就不是案件了。不是案件，我们法医的工作也就完成了。” 我点点头表示赞同，心想既然死者不是被他人杀死，那么即便是和杜洲有关系，杜洲也不是凶手。想到这里，我的心里踏实了一些。 接下来的工作，就是进行个体识别了。我拉开死者的下颌骨，准备对死者的牙齿进行观察；而大宝则开始用电锯锯死者的骨盆，准备拿下耻骨联合进行观察。 死者的牙齿非常洁白、干净和整齐。 “她的牙怎么这么干净？”我说。 林涛探头过来看看，说：“看起来她平时确实是有人看护的，是意外走失的。” 我点点头，看了看死者的牙齿咬合面说：“死者一颗蛀牙都没有，保养得不错。看咬合面，也就二十多岁的样子。” “这么年轻？”林涛惊讶道。 我说：“越年轻越好，有报失踪记录的可能性就越大。” 尸检结束后，但法医一方面要赶回去给办案单位提供法医学意见，一方面要把取下来的耻骨联合进行水煮处理，观察联合面形态从而更加精确地推断年龄。 而此时已经到了下班时间，我们也就各自准备回家。 虽然发现了一些杜洲的痕迹，仿佛是将工作推进了一步，但是面对茫茫人海，我们依旧无计可施。 在检查完女尸后，我的心里总是隐隐地觉得她和杜洲的失踪有着一些若有若无的联系。但这种直觉究竟从哪里来，我也说不清楚，更没有依据去支持。仅仅是因为两个现场距离比较近吗？我自己想不明白，就不再去深想，一心赶回家去，抓紧这些没有出差的时间，和儿子拉近距离、搞好关系。 带孩子的时间总是过得很快，一眨眼的工夫，就到了睡觉的时间。 一觉醒来，又是新的一天。 我刚刚走进办公室便接到了胡科长的电话。 “案件复杂了。”胡科长说，“昨晚我们局理化部门加了一晚上的班，能想到的毒物都做了，可是所有的检材都没有发现有毒物。” “啊？”我顿时有点蒙，愣了半晌才说，“那您觉得呢？” “如果要考虑是气体中毒的话，情况就有些复杂了。”胡科长说，“如果是气体中毒，我们提取的检材都不具备检验条件，必须得要血液。所以，今天凌晨，我去了医院，一方面调取了毛庭的病历档案，一方面也提取了他的血液。目前的结果，是排除了一氧化碳中毒；根据病历，二氧化碳中毒也可以排除。是不是有磷化氢等其他有毒气体中毒的可能，还在进一步检验。” “磷化氢中毒也常见于意外事件。在六七月份的时候，很多农户会收回稻谷堆在家里，然后为了防虫，会在稻谷上喷洒磷化铝。磷化铝会和空气中的水分发生化学反应，生成三氧化二铝和磷化氢，磷化氢是有毒气体，可以致人死亡。”我说，“但是现在不是季节，而且现场也没有存放稻谷的迹象。如果是磷化氢，岂不肯定就是命案？” 胡科长没有吱声。 “我们马上过去。”我说。 坐在龙番市公安局法医门诊，我们轮流翻看着毛庭的病历。 “毛庭现在情况怎么样？”我问。 “生命体征已经稳定了，但是不能说话，好像意识还是模糊的。”胡科长说。 “HBDB、CK和LDH都很高啊，但是炎症反应又不是很明显。”我沉吟道。 “什么乱七八糟的？”林涛一头雾水。 “羟丁酸脱氢酶、肌酸激酶和乳酸脱氢酶。”大宝解释道，“这些化验单几乎都提示了毛庭的心脏功能遭受了严重的损害。” “如果只是心肌损害，那还是要考虑一氧化碳中毒啊。”我叹道。 “可是刚刚出的结果，毛庭的血内，碳氧血红蛋白含量低于百分之三。”胡科长说，“毛庭平时吸烟，吸烟的人达到百分之四都是正常的。而如果是一氧化碳中毒，肯定要大于百分之十。” “可是，如果是一氧化碳中毒，也可以解释毛庭血中碳氧血红蛋白低。”我从书架上拿下一本《法医毒理学》，说，“从病历上看，毛庭是昨天早晨七点半就脱离了现场环境，并且一直接受吸氧治疗，一氧化碳会通过毛庭的肺脏原物呼出。有研究显示，正常情况下吸氧，一氧化碳的平均半排出期只有八十分钟。而我们是昨天晚上抽取的毛庭的血液，当然早就没有了碳氧血红蛋白。死者的血液提取了吗？” 胡科长点点头，说：“我马上安排人去重新拉出尸体取血。不过，死者的尸斑并没有樱红色的特征啊。” 我翻了翻书，说：“这个知识倒是不太常用的。其实一氧化碳中毒也分型，分为闪电型中毒、急性型中毒和慢性型中毒。我们经常遇见前两者，慢性型倒是不常见。前两者是环境里的一氧化碳浓度高，直接导致呼吸中枢麻痹而死亡。但是，如果现场一氧化碳含量正好是临界于致死量，很有可能出现慢性中毒，逐渐意识丧失，最终死亡。因为在意识不清的时候，现场一氧化碳含量逐渐减少，然而死者的心肌损害没有得到纠正，所以，最后的结局是心律失常死亡，而体内的碳氧血红蛋白含量并不是非常高，因此尸斑的樱红色表现也就不显著。” “可以解释了。”胡科长说，“可是现场环境不是很支持啊。你看，进入现场抢救的人，并没有中毒，而且现场的一氧化碳探测器也没有报警。” “是啊，这也确实不好解释。”我说，“不如我们重新回现场看看再说吧。” 我在现场的周围绕了一圈，直到现场墙外的窟窿引起了我的注意。 现场的那半扇窗户对应了厨房所在的位置，墙壁上的排气孔，只有十厘米的直径大小。可是昨天看现场的时候，我明明记得排气管有二十厘米的直径呀。 想到这一点，我连忙穿上现场装备，走进了现场。 “看到没有，这么粗的管子，其实是个摆设。”我说，“直径二十厘米的内管，其实是套在直径十厘米的外管上面的。” “你是说，内管的直径大，所以管子里的一氧化碳不能通过细了很多的外管全部排出？”胡科长摸着下巴说，“可是这个热水器使用了两年啊，之前都没有出过事情。” 我站到之前林涛站的板凳上面，看了看热水器内管的情况。 “这根内管是依靠塑料胶布黏附在墙壁的瓷砖上的，因为管口和墙壁被塑料胶布密封，所以虽然内管较外管粗，但是产生的一氧化碳不能通过其他途径排出，只能通过外管排出室外，所以没事。但是，可能是因为塑料胶布年久，黏性下降，所以脱落了。这样一来，内管管口不仅和外管连通，也同样和室内连通。产生的一氧化碳因为不能顺着管道迅速全部排出室外，有很大一部分通过管口和墙壁的缝隙排进室内。这就是中毒的原因。”我信心满满，“看起来，这一起中毒事件，是可以定性了。是热水器排气管未能按照规定安装而导致的意外事件。” 胡科长此时接了一个电话，说：“死者心血内的碳氧血红蛋白在百分之三十左右，虽然没有达到公认的致死量，但是足以证明是一氧化碳中毒了。” “我刚才说了，没有达到致死量，是因为从死者昏迷到死亡经历了一段时间，而这段时间里环境内的一氧化碳逐渐减少，死者体内的一氧化碳也被死者原物呼出一部分。”我说，“但是中毒没有及时得到救治，所以引起了慢性中毒、心律失常而死亡。这也可以解释，为什么那么多抢救的人进入现场，并未发现中毒症状。” 大家都在低头思考。 “我来解释一下现场情况吧。”我胸有成竹，“案发当时，毛庭在外间喝酒吃饭。先吃完饭的毛远大在里屋床上看书，而荣冬梅则在卫生间洗澡。因为卫生间和厨房是共用一个推拉门的，所以在洗澡的时候，厨房就对室内敞开了。因为洗澡，热水器产生的一氧化碳从管缝中漏出，导致室内的一氧化碳浓度逐渐增高。此时，里间的毛远大和外间的毛庭先出现了中毒症状，分别昏迷。毛远大也是因为有求生意识而从床上掉下。从室内瓷砖上的挂壁水珠上可以看出，室内密封环境特别好，而且荣冬梅这个澡洗了很长时间。虽然关门洗澡，但是一氧化碳同样进入了卫生间，导致荣冬梅身体不适。荣冬梅极度难受，没有穿衣服就拉开卫生间门走出来，这时候，她已经发生了呕吐和昏迷，丧失了自救的能力。而此时，热水器已经停止工作，而且随着荣冬梅的开门，推拉门把一氧化碳浓度最高的厨房给封闭了起来。经过将近一夜的时间，空气中的一氧化碳从窗户上五厘米的开口处慢慢散发了出去，但是丧失自救能力的荣冬梅和毛远大因为心律失常而死亡。外间的毛庭因为距离产气源最远，所以中毒症状较轻，但是也出现了严重的心肌损害。你们看，这样解释全部案件，是不是很合理？” 胡科长拍了拍手，说：“完全可以解释了。不过，如果要结案，还需要进行侦查实验，确定热水器打开的情况下，是不是能产生大量的一氧化碳进入屋内。如果可以的话，就可以顺利地结案了。” “在这么密闭的空间里，做侦查实验还是有些危险的吧。”我见胡科长拿出自己携带的一氧化碳空气探测器，说。 “再危险也要做啊。”胡科长笑了笑，说，“杜绝一切明火。我放下探测器，然后打开热水器，大家一起离开。” 打开洗澡间的水龙头后，热水器开始轰鸣了起来，我们几个人一起退出了现场。 不到一分钟，探测器便开始叫了起来。 “秦科长推断得不错，现场产生一氧化碳的速度非常快。”胡科长屏住一口气，迅速冲进现场，先是关了卫生间的热水开关，然后用相机对探测器上的数值进行拍照，最后打开窗户透气。 “看来证据确凿了。”胡科长满意地说。 “等等。”一个可怕的想法在我的脑中一闪，“刚才您进去的时候，有没有注意到那个一氧化碳探测器在不在响？红灯有没有亮？” “没有。”胡科长肯定地说。 “那就不对了。”我说，“之前我的推论，如果我们到现场的时候，现场一氧化碳已经散去，探测器不响不亮是正常的；案发当时即便探测器响了亮了，当事人已丧失自救能力也可以解释。但是，为什么我们做实验的时候，它也不响不亮？” “聋子的耳朵，摆设？”林涛说。 “这是个新热水器，既然费劲打了钉子把它安装了上去，没有道理不给它通电使用它啊！”我说。 “那你是什么意思？”胡科长说。 我没有吱声，静静地等待了一会儿，估计现场产生的一氧化碳差不多都散尽了，重新进入了现场。 我站在板凳上盯着热水器和管道左看右看，然后对着林涛说：“你，要不要上来看看？” 林涛点头会意，拿着勘查灯登上了板凳。 我在下面等着。 “看清楚了，一氧化碳探测仪的电线被拽断了。”林涛说，“因为电线是穿过吊顶的，所以暴露在吊顶外面的地方没有异常，其实在吊顶里面的部分已经断了，所以自然就没有电了，也就不会报警了。” “断口新鲜吗？”我汗毛一立。
