Chapter 7 Case 5: Chariot of Flame

Zero Profit Supermarket is the largest supermarket in Longpan City, and there is an endless stream of customers every day.Its location is also the center of the most commercially concentrated area in Longpan City, and it covers a large area. The square in front of the zero profit supermarket is even larger than the citizen square in Longpan City, and it is all used for parking.Every day after get off work, the parking plaza of Zero Profit Supermarket becomes the busiest place in Longpan City, with a constant flow of vehicles. Cao Qiang is a policeman in the Political Department of the Municipal Public Security Bureau. Because he works in an agency, his time is relatively stable compared to his wife who is a traffic policeman.Therefore, Cao Qiang took on the "heavy task" of going to the supermarket to shop and buy vegetables every day.

On this day, as usual, Cao Qiang came to Zero Mart Supermarket to buy vegetables after work.After buying groceries, push the shopping cart to the parking plaza.In this season, the sunset time is around 6:10 pm, and half an hour after sunset, the sky is basically dark.When Cao Qiang walked out of the supermarket, it was half past six and it was already dark. The parking lot on the west side has the least amount of vehicles in the entire parking plaza.Many people are reluctant to stop at the West Square because they need to go around the entrance to get to the west side.But precisely because there are few cars, Cao Qiang, who is not afraid of trouble, chooses to park here every time. Not only is it easy to find a parking space, it is also convenient to enter and exit, and the probability of being bumped by others is small.

When approaching his car, Cao Qiang caught a glimpse of a red light not far away.In a darkened environment, any glimmer of light is easy to spot. Cao Qiang looked at the red light, but he didn't see it clearly.It was as if this beam of light emanated from a car.Cao Qiang looked left and right, probably because he bought vegetables quickly and left the supermarket before others, so at this time, there were really no other people in the West Square.Out of professional sensitivity, Cao Qiang felt that he should take care of this business. Cao Qiang put the contents of the shopping cart into the car and walked towards the northwest corner where the red light was.Sure enough, there was a car parked in the parking space. Judging from its appearance, it should be a high-end car.When approaching the car at the corner of the parking lot, there was a sudden "bang", which made Cao Qiang stagger in fright.

Cao Qiang was not mistaken, the red light really came from the car.And, red light is fire! The sound of "bang" was the fire that blew up the window glass.With this loud noise, billows of smoke rolled out of the car.Cao Qiang was so frightened that he took a few steps back and shouted, "It's on fire! Come and put out the fire!" At that moment, Cao Qiang caught a glimpse of the license plate number of this blue Mercedes-Benz, which was the car at the home of his colleague Dong Jianwu. At the same time as the flame rolled out from the car window, the fire engulfed the car in an instant, even if there were a hundred Cao Qiang, there was nothing they could do.Trembling, Cao Qiang dialed 119.

At this time, some people began to gather in the west parking lot, including customers who had just come out of the supermarket, security guards from the supermarket, and passers-by.Everyone hurriedly knocked on the fire hydrants in the supermarket building to collect water, some with basins and some with buckets.There is no way to recover the blue Mercedes, and everyone is trying to keep the other cars parked near the Mercedes as much as possible. After a while, a fire truck roared to the scene.Within a minute, the water cannon started spraying on the blue Mercedes.Standing behind the fire truck, Cao Qiang dialed Dong Jianwu's cell phone with trembling hands, but no one answered.

When the fire was extinguished by the fire brigade, the blue Mercedes-Benz had become a scorched car frame, the tires had been heated and leaked, and the license plate had been burnt and fell off, which was particularly eye-catching in a pile of black charcoal. "Oh, such a good car, will it spontaneously ignite?" "It's still so cold, how can it spontaneously ignite?" "Is the air conditioner turned on?" The onlookers were talking about it. After a while, a man pushing a shopping cart broke through the crowd and walked into the scene, looked at the scorched car frame, and sat down on the ground.

"Brother Dong, why can't you get through on your phone? What's going on? What's going on?" Cao Qiang helped the man sitting on the ground and asked loudly, drawing the attention of the onlookers to this place. Dong Jianwu sat on the ground in a daze, and suddenly jumped up with a shout: "Xiaoling! Xiaoling is in the car! Where is Xiaoling?" At the same time, the firefighters who approached the car to search shouted loudly: "Platoon leader, there is a dead body in the car!" In the afternoon, our investigation team received an invitation for a letter and visit, and went to Longxi County under the jurisdiction of Longpan City to examine and review a dead body.This is the corpse of a suicide case. The family members are not satisfied with the conclusion of the forensic examination by the county-level public security organ and demand a re-examination.In order to ensure the accuracy of the original appraisal conclusion, at the request of the family members, our investigation team, together with Han Forensic Medicine from the Longpan City Bureau, went to Longxi County for re-examination.

An autopsy is not difficult, but interpretation is not.It is not an easy task to use the most common language to explain some of the signs on the corpse to the family members of the deceased to gain their understanding. So this not-so-difficult autopsy job was carried on until after six o'clock. "Why did I feel a gust of wind blowing directly on my neck during the examination just now?" Dabao took off his dissecting suit and touched his neck. Forensic doctor Zhao from Longxi County smiled, pointed to the window behind Dabao and said, "Look, this piece of glass is broken. It's been a long time and no one has repaired it. It's windy today, so you're standing right in front of the wind. , so the wind is blowing on you."

"Why not fix it?" I went to the window and looked at the breach, and said, "It must have been a few months? How did you get here in winter? In summer, such a big breach may be caused by the air conditioner in the anatomy room." Doesn’t it work? Is it because the bureau doesn’t allocate money?” "That's not true." Forensic Zhao pointed to a piece of glass in the corner and said, "There is no shortage of money. You see, we all cut the glass according to the size. But we can't change it, and we can't find anyone to repair it." what." "Why?" Dabao was surprised.

"People don't want to work in funeral parlors," Forensic Zhao said, "let alone an anatomy room." "Oh my god, what about it?" Dabao felt incredible. "Look." I smiled wryly, and said, "I used to say on Weibo that we work in the wind, in the rain, in the hot sun, and in the cold wind. Is the work harder? Yes, we are not physically as hard as manual laborers, but we still have to bear more psychological pressure. There is panic, nausea, and blood. Look, no one wants to come to the funeral home. And we go in and out of here every day, directly touching the dead bodies."

"Don't complain." Dabao smiled and took out a tool box from our survey car, and said, "I'll help you change the glass." "You know how to change it?" Forensic Zhao watched suspiciously as Dabao climbed onto the instrument table and began to work with a screwdriver. "Let me tell you, Master told me that to be a forensic doctor, you have to be a 'six artisans in one' and you have to know everything." Dabao gritted his teeth and turned the screwdriver, said. "What is the unity of six craftsmen?" Fayi Zhao was very interested. "Because you want to use a saw, master the art of a carpenter; because you need a bone chisel, master the art of a bricklayer; because you need a pith extractor, master the art of a locksmith; because you need to shave your head, master the art of a barber; preserve The bones need to be painted, so master the skills of a painter; because they need to be stitched, so master the skills of a tailor." Dabao is like a treasure. "If you are serious, you can't remember." I scolded with a smile, "We still have to pick up ashes at the scene of the fire, do we still have the skills of cleaners?" Doctor Han, who had gone out to wash his hands, returned to the dissection room and said, "There was a fire in the city, and one person died." Everyone looked at me with black lines on their faces. I spread my hands and said: "If there is any similarity, it is purely coincidental." Han Fayi came in without knowing it, and said, "We have to go back. Section Chief Qin, Mr. Chen asked me to inform you and rush to the scene with us." "Do all the dead have to go to the fire?" I rubbed my sore waist. "You have a crow's mouth, the matter you caused, just don't go?" Dabao said. Forensic doctor Han said with a serious face, "It may be because the police from the political department of our city bureau were involved." We dragged our tired bodies and boarded the police car driven by Han Liang.Even Dabao, who was tireless and restless when he left the scene, muttered: "The matter of Duzhou has not been settled yet, but the case here is non-stop. There are frequent accidents of cars spontaneously igniting, and we can't all run away." Let's do it again." "By the way, speaking of the incident in Duzhou, is there still no news in the past two days?" I asked, "The source of the highly corrupted unknown female corpse has not been found yet?" After thinking about it for two days, my intuition still exists. I always feel that the two incidents of the unknown female corpse and the disappearance of Duzhou are somewhat related. Cheng Ziyan said that he asked Lin Tao for advice when he had a problem, and let Lin Tao sit in the survey vehicle of the Municipal Bureau. Han Fayi had no choice but to squeeze into our car.Asked this question, which happened to be under the jurisdiction of Han Forensic Medicine, he said: "I don't know about the disappearance of your friend, but the case of the unknown female corpse, our work has been completed. Histopathological examination supports that the deceased may be caused by asthma. She suffered from bronchospasm and laryngeal edema, and finally died of suffocation. The remote environment at the scene and the failure to receive timely treatment were the auxiliary causes of her death. We have also separated the pubic symphysis, and the deceased was judged to be about 24 years old and had no childbirth history." "Where's the missing persons database?" I asked. Forensic doctor Han said: "The DNA has been stored, and rewards have been placed in many places. So far, no one has come to identify the body." "It's weird." I said, "For such a young child, her family should take good care of her. Why is no one looking for her after she lost it? Damn, it should be someone nearby." The search for the source of the corpse was fruitless, which did not disappoint me unexpectedly, but instead filled my heart with doubts. "After all, he doesn't look like a normal person, and judging by his clothes, the family conditions should be very poor." Forensic doctor Han said, "Now I'm afraid that this is a case of abandonment by relatives." "If you want to abandon it, you have already abandoned it." I said, "And wait until the age of 24?" Forensic Doctor Han spread his hands, expressing his helplessness.Everyone was silent, each thinking about the problem. Longxi County is not far from the urban area, and the Municipal Bureau and our investigation vehicle arrived at the site very quickly.Because it is located in the most prosperous area of ​​the city center, a large number of onlookers gathered around the scene, which even caused traffic congestion on several main roads near the scene.A squadron of traffic policemen walked back and forth busily around the scene, trying their best to direct the traffic and drive away unrelated people who parked and looked around. Precisely because of the large number of onlookers, the on-site protection has become more stringent.The Municipal Bureau mobilized the standby police force from three nearby police stations, and cordoned off the entire west square of Zero Lee Supermarket.All the vehicles that had been parked in the west square had been driven away by their owners. Dong Jianwu was helped into a police car by the police because of his excessive sadness.Cao Qiang was gesturing and talking to the police. "Have you heard? It was a policeman's wife who died." "Does the policeman drive a Mercedes?" "Yeah! It must be from corruption." "Death deserves it." A few onlookers were chirping, not noticing us who just got off the bus. "Who said the police's family can't be rich?" Han Liang may have felt the same way, rushing over and said, "Can't the police's father be rich? Can't the police's wife be rich? Which law stipulates that the police must ride a moped to and from get off work? Yes? The members of the police’s family conduct legal business in accordance with the law and regulations, and don’t want to be honored by the public, but rely on their own ability to make money, isn’t that okay? How can you speak against them? Are you worthy of the deceased?” I pulled the angry Han Liang over and said in a low voice, "Do you have to be so excited? Just say what others say." Those people who chewed their tongues were choked up by Han Liang's sudden few words, and only dropped one sentence: "Crazy." I calmed down Han Liang's emotions, walked up to Cao Qiang whom I knew before, and asked, "What's wrong?" "Maybe the car spontaneously ignited." Cao Qiang calmed down and said, "Dong Jianwu's wife, Bo Ling, burned to death in the car." Next, Cao Qiang told the whole story of what he discovered. I frowned after listening, and then said: "Cars spontaneously ignite. Usually, there is a problem with the engine, and the engine will burn first. Then what we see should be the front of the car. But from Director Cao's words , The point of fire should be inside the compartment. Unless there is a fire source in the compartment, otherwise it will not be the first fire in the compartment, and the smoke will only come out after the glass is shattered." "Did Bo Ling and Dong Jianwu smoke before their death?" the host investigator asked the investigating police next to him. The policeman shook his head and said, "No smoking." "What would ignite the car?" said the host investigator, "and the fire is still so big! Can you do a combustion aid test?" "It's meaningless to test the combustion aid of the car." I said, "There is gasoline in the fuel tank of the car. After burning, the gasoline in the fuel tank will naturally be used as a combustion aid to support the combustion, so the combustion aid must be able to make gasoline components, but this shows that what?" "Then based on your experience, why did the car catch fire?" Cao Qiang interrupted and asked. "There are many development processes of vehicle combustion." I said, "But according to the situation you described, there should be a fire source in the car, which ignited flammable items such as seat cushions. As the fire became bigger and bigger, the following The row of seats was destroyed. We know that the fuel tank of the car is actually under the rear seats. The temperature rises, the gasoline boils, and it may overflow from the opening where the fuel tank connects to the car, causing the fire to increase. Finally, because of the high temperature , air pressure changes, window glass shattered." "That is to say, was it because of carelessness that we left a kindling in the car, which caused this tragedy?" Cao Qiang looked at Dong Jianwu who was sitting in the police car in the distance. "Do you want to ask Dong Jianwu?" said the lead investigator. I shook my head and said, "I have a question now, that is, since the fire started slowly, why didn't Bai Ling escape from the car?" "That's right!" said the lead investigator, "It's not driving, or the car is malfunctioning and the door cannot be opened. Park here well. If there is a fire in the car, it is easy to escape. Unless, when the fire broke out, he was already dead. gone?" I was silent and didn't speak. The investigator in charge looked at Dong Jianwu in the distance, and said to me in a low voice: "Should we control Dong Jianwu first?" Cao Qiang immediately objected: "He is my brother in our police team! How could you doubt him?" "Otherwise, in broad daylight, who would come to this busy place to kill people?" The lead investigator had his own basis. "Is there any investigation into the backgrounds of Dong Jianwu and Bo Ling?" I asked. The investigator in charge of the peripheral investigation nodded and said: "They are all from our own team, and it is very convenient to investigate. Dong Jianwu joined the police ten years ago. He first worked in the Longcheng Police Station for six years, and then he was selected for the City Bureau. The department serves as the deputy chief staff member. Bai Ling is a local, and her father is a real estate developer. After graduating from university, she has been working as a department manager in her father's company, earning a lot of money. The two got married four years ago after being introduced Yes, there is a two-year-old child who has always been taken by Bo Ling's parents. The two live in a nearby community and often come here to shop. The relationship between the husband and wife is very good, as my colleagues in the Political Department can confirm. " "Could it be for property?" said the lead investigator. I smiled.An excellent investigator must have the spirit of doubting everything. In this regard, this investigator has done a good job.I said, "What about the trajectory of today's activities? Does Dong Jianwu show any signs of abnormality?" "There is no sign of abnormality." Cao Qiang interjected, "We are in the same office, and he is very normal." The investigator nodded and said, "I really didn't find any abnormal signs. When I got off work at 5:30 this afternoon, Bai Ling drove her Mercedes-Benz to the city bureau to pick up Dong Jianwu. According to the monitoring on the road, the car should be running normally as usual. I drove into the supermarket parking lot, and it was 5:42. According to the monitoring in the supermarket, Dong Jianwu walked into the supermarket alone at 5:45, and his condition was normal. According to Dong Jianwu’s own account, Bai Ling left him at the gate of the supermarket, and then found a place to park. After he went shopping, he called Bai Ling again. The onlookers in the parking lot on the west side had an ominous premonition, so they hurried over." "There is no monitoring in such a large parking lot?" I asked. The investigator shrugged and said: "We have notified the police station in the jurisdiction, and hope that the supermarket will take rectification actions in the next step. Except for the parking entrance and exit and the supermarket, other places are not monitored. The parking lot is open to pedestrians. If you are alone After committing crimes on foot, you can leave the scene through countless unmonitored paths." "It's a pity that there is one missing clue to solve the case." I said, "However, there is almost no possibility of Dong Jianwu committing the crime." "Are you talking about time?" Dabao asked. I nodded and said, "I remember that the fire investigation department once conducted a detection experiment. It took only ten minutes for a small flame to spread to the entire compartment without combustion aids. If there were combustion aids, It will be faster. Director Cao said that at 6:30, the fire in the car had not yet broken the glass, and we worked hard, and the ignition time would not be earlier than 6 o'clock. But Dong Jianwu entered at 5:45 The supermarket, the time does not match." "Wouldn't it be a timed ignition device?" Dabao said. "That's an extremely low probability event." I said with a smile, "Can you make this kind of device? Besides, if the fire really started on a regular basis, we will find out by cleaning up the ashes in the vehicle." "No matter how small the probability is, we must be vigilant." The host investigator supported Dabao's point of view, "We want to temporarily control Dong Jianwu." "As I said before, it is highly suspected that Bo Ling was dead when the fire broke out, or at least lost the ability to save herself." I said, "Get off work at 5:30, enter the entrance of the supermarket parking lot at 5:42, Dong Jianwu He entered the supermarket at 5:45, so he only had three minutes to park the car, kill his wife, and set the timer. Isn't that ridiculously short time?" "If Dong Jianwu's crimes are ruled out, most of the murderers who come to kill people at this time and place are desperadoes seeking revenge." The lead investigator said, "Because no one knows how long Dong Jianwu will be away. No one knows whether the crime committed here will be seen by passers-by." "Before jumping to conclusions," I said, "we have to look at the scene and the body first." Because the entire west parking lot is surrounded by security tape, the place where we speak is actually far away from the central scene.We put on our survey equipment and walked towards the burned Mercedes-Benz at the center site on foot. On the way, I saw that Cheng Ziyan had brought more than a dozen technicians from the city bureau and sub-bureau, and began to assign tasks to the west parking lot.Judging from this posture, it is necessary to conduct a carpet search of the entire parking lot and extract evidence. For outdoor scenes with such a large scope, there is no safer way to extract physical evidence than doing so. Several of our forensic doctors walked to the burnt car along the safe passage drawn by the trace inspection department.If it weren't for the burned Mercedes-Benz logo on the front of the car, it really wouldn't be a luxury car. The car has only the frame left, and even the interior of the car no longer exists, only the metal frame remains.There was a vast ocean under the car. The water sprayed by the fire brigade just now accumulated in the car and then flowed down from the burnt car bottom.The windows of the car were blown by the heat and scattered inside and outside the car.The interior of the car was so black that it was almost impossible to tell where the body was.The paint on the car had been melted by the heat, and it was hard to tell that it was a blue car. I put on my gloves and opened the door.Because the hinges had been deformed by heat, as I exerted more force, the door made an unpleasant "squeak" sound and was pulled open. "The door is unlocked," I said. "This Mercedes-Benz is automatically locked when it is turned on, and automatically unlocked when it is turned off." Han Liang said while covering his nose. It's not that I haven't noticed Han Liang's movements, the air is really full of charcoal and dust. "It's all burned like this, can you still tell which Mercedes-Benz it is?!" Dabao was very surprised. "It means that the vehicle is turned off?" I looked at the gear of the car with my head.But it was almost burnt, and I couldn't see the gear it was in. "Of course it's off." Han Liang pointed to a small pedal next to the brake pad.This Mercedes-Benz is a foot-operated handbrake, and the pedal is stepped on, indicating that the vehicle is in the state of pulling the handbrake. "It's normal to turn off the engine." Dabao said, "The car is parked here waiting for my husband, so it can't be turned on? What a waste of fuel. Besides, the weather is neither cold nor hot, so there is no need to turn on the air conditioner." "So, anyone can get in the car by opening the door." My consideration is different from that of Dabao. "This car is too complicated." Dabao said, "I probably saw a dead body." In the center of the charred bottom of the car, the outline of a corpse can be seen.Because the skin on the upper surface has been scorched black, it is almost integrated with the charcoal, making it difficult to detect. The position of the corpse was very strange. It was not sitting in the cab or lying on the rear seat, but the upper body was between the driver's seat and the co-pilot, with the head protruding into the rear space. "Why is this posture?" I was the first to ask, "The whole person is stuck in the space between the driver's seat and the co-pilot, with his head poking toward the back row." "Ah! I see!" Dabao said with a look of sudden realization, "Could it be that he saw the fire in the back row, so he leaned in to put out the fire?" "Damn." I directly denied, and said, "Anyone who finds that there is an accident or even danger in the back seat of his car, the first reaction is of course to get out of the car and open the back door. It is so convenient and safe. How can you put your body in such an uncomfortable position?" Looking behind to avoid danger? Moreover, we can find out after a closer look that both arms of the deceased were actually stuck in the space between the driver's seat and did not extend to the rear." "It seems to be." Han Liang said, "It seems to be a relatively passive position." "How...how did this corpse get out?" Dabao said. "It's not too easy to do." I said, "If we clean up all the ashes in the car, it will take four or five hours. It will affect the traffic here too much. The best way now is to use Wrap the whole car in plastic, then call a tow truck to take the car to the garage. It's well lit and easy for us to clean up the ashes. However, no garage will allow us to pull a car with a dead body in, so, have to First find a way to get the corpse out and send it to the funeral home." All fire scenes, especially vehicle fire scenes, have a necessary work, which is "ash picking".We refer to it as ash picking for short, but it is actually a very heavy on-site investigation work.The technicians will clean up all the ashes at the scene bit by bit, look for some unburned substances from the ashes, and then use these substances to analyze the case. For example, at the scene of a car burnt down, if no metal objects such as the windshield of the lighter are found after the investigation of the ashes is completed, there are only two possibilities: use a match to ignite the self-immolation; The case in front of us is highly suspected to be a murder case, so "picking up ashes" is very important.It is even more important than the autopsy. After all, most of the corpses have been burned, which has caused certain difficulties and uncertainties to the inference work of the autopsy.However, picking ashes can reveal many clues, such as whether there are fire tools, whether there is a so-called timing ignition device, whether there are other murder weapons, and whether the deceased’s belongings are missing. Now that the next step of work has been formulated, we immediately get busy. Several forensic doctors opened the four doors of the car and prepared to move the corpse from four directions.Considering that it is a fire scene, the corpse is likely to become brittle due to burning, and vigorous movements may destroy the original appearance of the corpse, so everyone carefully moved various parts of the corpse under real-time video recording, trying to form a joint force , Lift the body parallel. After everyone worked hard for ten minutes, the body was finally completely separated from the charred car, and then moved out from the co-pilot's door. No matter how the police in charge of protecting the scene drove them away, the onlookers just refused to leave.According to some current regulations, if the onlookers don't leave, the police have nothing to do.The masses randomly used their mobile phones to take pictures of the dead, and the police were helpless. The moment the body was carried out, I heard a buzzing sound outside the warning zone in the distance, as if a pot had exploded.I really don't understand, what's so good about this corpse?It's so fun and interesting.I also admire the eyesight of the onlookers. After all, there is a distance of tens of meters, and they can all know that the charred thing we carried out is a corpse! We carefully put the body into the body bag, zipped it up, and let the comrades of the funeral home take the body away as soon as possible.Then, we wrapped the car body with an oversized rain cloth to prevent the loss of items in the car during the towing process. "It's good that the scene is next to the supermarket, and such a large rain cloth can be found." I said while wrapping the car body. Seeing the burnt-out car slowly being towed up by the trailer, I called on everyone to rush to the repair shop as soon as possible.If you arrive early, you can start examining the body before midnight.Lin Tao was left behind to clean up the ground with Cheng Ziyan. It's much easier to clean up the ash from a burnt-out car than it is from a burnt-out room.I, Han Fayi, Xiaoyu and Dabao were in charge of a car door area and started to clean up the ashes.Han Liang took a large sieve and gradually cleaned up the ashes we cleared up for further washing and sieving. Time passed by like this, because the action of picking up ashes was relatively large, and soon the four of us became "little blacks".The car was full of ashes, and all parts of the car bottomed out almost at the same time. Among all the objects found during the rough sieving process, a police badge we found on the console of the co-pilot position is the most eye-catching.According to a burnt and deformed steel ring around the police badge, we are almost certain that this should be a large police cap. "What did Dong Jianwu put his big cap here for?" said the investigator in charge of the contact, "Isn't this looking for trouble?" People who have just become police officers usually like to show off in police uniforms everywhere.After a long time, you will find that wearing a police uniform when doing private affairs is the most inconvenient option. "Could it be someone who hated the police and saw this hat and just picked the target temporarily?" Dabao said, "This person is too unprofessional. This is obviously a man's big hat, and the owner is a woman. .” "It's not uncommon to take revenge on the family members of the police." The investigator said with a chill. "There's nothing wrong with a rough sieve." I said, "It's all parts from the car. No parts that could catch fire were found, and there was no so-called timing device. However, a mobile phone motherboard was found, and nothing else was found. Yes. Han Liang, how is your fine sifting going?" Han Liang frowned, staring at his gauze gloves that had been stained black, and said, "I didn't see the windproof cap of the lighter. The things that ignited should be taken away." "Hmm." I nodded, "Isn't there anything else?" Han Liang shook his head, then nodded again, and said, "However, I always feel that something is missing." "What's missing?" Dabao squatted wearily beside Han Liang, picking up the small objects that Han Liang sifted out, and looked at them carefully. "I took a look, and there are many small metal objects in the ashes, such as zippers, buttons and so on." Han Liang said, "Most of them can be seen from the brand. If nothing unexpected, the deceased should be wearing Gucci (Gucci) Tops, Prada pants, last year's style." The investigator in charge of the liaison flipped through the notebook, stared at Han Liang with wide eyes, and said in disbelief, "This...you can see this?" "Of course, the metal parts of each style of clothing are very particular." Han Liang said lightly, "But I searched all the metal parts, and none of them belonged to the handbag." I lowered my head and thought for a while, my eyes lit up, and I said, "It stands to reason that this young lady covered in famous brands must have an expensive handbag no matter what?" "Yes, yes." The investigator flipped through the notebook and said, "According to Dong Jianwu's account, Bo Ling was carrying the Dior handbag she bought the latest that day. It was small in shape, pink, with square and diamond-shaped protruding checks. The face kind." "Lady Dior, right?" Han Liang said. "Uh..." The investigator scratched the back of his head. "That bag has a characteristic." Han Liang said, "There is a metal pendant, which is a pendant with a few letters of Dior. And there are some metal parts with a logo (logo). These things will not It was burned, but I didn't sift it out. Especially the 'O' letter pendant, which is very big and easy to find." "Very good!" I smiled slightly and said, "Han Liang's thinking has really improved very quickly. In many cases, we not only need to discover what is there, but also what should be there and what is not." Han Liang scratched his head, smiled and said nothing. I took off my gloves, clapped my hands, and said, "It's eleven o'clock. There are still nine hours until the project meeting at eight o'clock tomorrow morning. If we still want to sleep well, there are only three hours of work now." Now, hurry up and go to the funeral parlor." The surface of the body was almost completely charred, but there were still some fragments of clothing stuck to the skin. Little by little, we peeled off the pieces of clothing and found that there were also pieces of fabric stuck to the neck of the deceased. "You won't be wearing a scarf this season, right?" I picked up the fabric fragments with tweezers and looked left and right. "No, um, no," said the investigator. "It looks like this should be a seat belt!" I said. "Seat belt?" Dabao said, "Why does the seat belt stick to the neck? It shouldn't reach there!" "It seems that the seat belt has become the murder weapon of the criminals." After I finished speaking, I used the hemostatic forceps to clamp the burnt eyelids of the deceased, but no obvious spotting bleeding was seen. "Seat belt strangulation?" Dabao was dissecting the torso of the corpse at this time, and said, "But the internal organs of the corpse are not congested, they are all pale, and there seems to be no obvious signs of suffocation." "Pale?" I was a little puzzled, and dissected the dead man's neck. The neck skin of the deceased had been scorched, and the damage pattern of the skin could not be seen clearly, but there was no bleeding in the superficial and deep muscles of the neck, and there was no fracture of the hyoid bone or thyroid cartilage. I said: "Although the neck of the deceased was covered with a seat belt, it seemed to be a simple restraint action, and no lethal force was exerted. It should not be the cause of death. However, there were no obvious cracks on the surface of the torso and neck. There is no breach in the internal organs, so how can the internal organs appear ischemic?" "There was no blood at the scene." Dabao said. "It's normal for there to be no blood at the scene." I said, "The blood has deteriorated after being burned at high temperature, and we won't be able to find any traces." "Could it be here?" Forensic doctor Han was examining the leg of the deceased. At this time, he pointed to the opening on the inner thigh of the deceased with a hemostat and said. The skin of the dead was charred, dried out, and cracked, so it was difficult to tell where the damage was and where it was burnt.However, the gap pointed out by Forensic Doctor Han seems to be a little different. I quickly picked up the scalpel and performed a local dissection on the deceased's right thigh.Forensic Doctor Han was right. It was not caused by burns, but three wounds.Two of the three wounds penetrated deep into the muscle, but one wound penetrated directly into the muscle and punctured the femoral artery. We separated both ends of the ruptured femoral artery and took pictures. "There is a small amount of soot and charcoal in the deceased's trachea." Dabao continued to dissect along the neck incision I just opened, and said, "It shows that the deceased caught fire when he was dying. But when the fire was not strong, she was already dead." "Stabbed with a knife, strangled by a seat belt, and caught fire when he was on the verge of death." I said, "There is no doubt that this is now a homicide." As soon as the words fell, Lin Tao, Cheng Ziyan and others walked into the dissection room. "Your work is also over?" Lin Tao said. I nodded and said, "It must be a murder case. As for the clues, I haven't found anything yet. I have some scattered ideas, but I still need to sort them out. How about you?" Lin Tao raised the evidence bag in his hand, and said, "I'm exhausted. There are no footprints or anything. I brought back seventy-two cigarette butts." "Hey, there are so many." Dabao said, "Is it because the cleaners are slow to work, or the quality of our citizens needs to be improved?" I pondered for a while and said, "Yes! Maybe the key to solving the case is these cigarette butts!" Late at night, in the forensic pathology laboratory. 我们面前的一张大台子上，平行排列着那七十二枚烟头。 我手持着一个放大镜，戴着口罩、头套和手套，一枚枚地观察。 大宝在我的身边打着哈欠，说：“你这是不准备睡觉啦？” “我说了我一个人就可以。”我笑了笑，说，“他们不都回去睡觉了吗？你也回去吧！陪我耗着也没用。” 大宝摇摇头，说：“回去睡沙发，不如在这里靠着躺椅。” “杜洲失踪有半个月了吧？”我说，“我看啊，恐怕真的是凶多吉少了。” 大宝没有回答我，我以为我说错了话，正准备解释，却听见大宝均匀的鼾声响起。原来他靠在我身后的躺椅上，睡着了。 我无奈地笑了笑，继续观察眼前这些烟头。 烟头有新有旧，品牌不同。我首先按照香烟的品牌把烟头分成几个部分。然后每个部分按照新旧不同再次分门别类。 就这样分着分着，线索突然就跃入了眼帘。 我掩饰不住内心的喜悦，拿出相机啪啪地拍照。 闪光灯把熟睡的大宝给惊醒了，他擦着口角的口水说：“怎么样了？” “好消息。”我说，“不过对DNA室值班的兄弟来说，可不是什么好消息。因为，他们今天晚上要熬夜加班了。” 虽然睡眠不足四个小时，但是第二天一早，我还是精神抖擞地来到了龙番市公安局刑警支队的专案组。在专案通报会开始后不久，到达了专案组现场。 “看大家的表情，应该是查找死者矛盾关系未果吧？”我坐下来后，直接开门见山。 “是啊，没法查。”主办侦查员说，“董建武当过几年的派出所民警，还管的是案件办理。那小偷小摸就不知道送进去多少。你说，和他有仇的人，实在是多了去了，怎么查啊？现在想想，这个会议室里都人人自危了吧？就不说董建武，柏玲的爸爸，柏丰利，在生意场上摸爬滚打几十年，逼倒了无数公司，这得罪的人也是多了去了。” “矛盾关系没法查，那就查查侵财的前科人员吧。”我淡淡地说。 “什么？”赵其国局长有些诧异，打断我的话，说，“你是让我们更改侦查方向？” I nodded. “侵财？”主办侦查员显然并没有激烈反对我的意见，说，“可是我们办了这么多年的案件，在人多车多的地方，下班高峰，用抢劫的方式来侵财的，还真是很少啊。” “既然是很少，就是说不是没有，对吧？”我说。 “时间、地点不对，咱不说。”另一名侦查员说，“据我们所知，董建武把自己的警帽放在操作台上，别人一看就知道是警察的车。抢劫还专门挑警察的？这不是增加风险系数吗？没有必要吧。除非就是想好了专门朝警察去的。那么，因仇的可能性就更大了。” “既然帽子是放在操作台上的，夜幕降临，车灯再开着，在车前的人，可以看清操作台上有什么东西吗？”我说。 大家可能是觉得我说得有道理，都没有说话。 “那……侵财有什么依据吗？”赵局长问。 我点了点头，说：“事情还得从死因开始介绍。死者是右侧股动脉断裂，导致急性大出血而死亡的。在濒死期，现场起火。在火势变大之前，死者已经死亡了。因为死者皮肤烧焦了，所以我们不好判断凶器的具体形态，但是可以断定是一把不短的刺器。除了被刺器刺伤以外，死者在死前还被车子的安全带勒颈，不过这个勒颈的动作，并不是她死亡的原因。” “用这种方式杀人？”主办侦查员说。 我点点头，说：“股动脉很隐蔽、很深，通常是用刺器刺击别人的时候不小心导致破裂，真的想去割断股动脉，除非是学医的，其他人还真不一定能找对地方。所以，我觉得这起杀人案件，起初的想法并不是杀人。既然起初的想法不是杀人，那么侵财的可能性就是最大的。” “就这些？”主办侦查员说。 我摇摇头，说：“当然还有。这是第一点。第二点，我们来重建一下现场。” 说完，我打开幻灯片，播放车辆里的尸体最原始的体位，说：“死者处于这个体位，显然是有人从后座，用驾驶员安全带从后面勒住死者的颈部，然后往后拖拽形成。但是处于这个体位，又怎么用刀来刺到位于驾驶室下侧的右腿呢？显然是够不着的。唯有一个解释，那就是副驾驶也有一个人，用刀刺击了死者的大腿。这起案件的作案人，应该有两个。既然有两个人，一个人已经从后面控制住了死者，为什么死者还不用手来抵抗？而且，此时死者的胸腹部都已经完全暴露给副驾驶的凶手，如果是为了杀人，朝胸口捅，是不是比捅腿来得更快更保险？” “还是证明了凶手开始的目的，并不是谋人。”赵其国局长点点头说。 我说：“不仅如此，我认为死者不去用手拉扯勒住她颈部的安全带的唯一原因，就是手上有东西。我们来大胆推测一下吧：柏玲停车熄火后，车锁自动打开，她坐在车里玩手机。这时候，两名凶手一名拉开副驾驶的门，另一名同时拉开后座的门，都钻进了车里，关上车门，持刀抢劫。性格刚烈的柏玲仗着自己的丈夫是警察，丝毫不畏惧，坚决不把自己的迪奥手提包和里面的财物交给凶手。后座的凶手于是用安全带把她的颈部勒住，往后拉，让她难以护住自己的包，却不下狠手勒死她。然而，副驾驶的凶手依旧不能从她的手中抢下手提包，只有用捅腿的方式来让她放弃。未承想，这一刀直接要了她的命。” “车辆灰烬里，我们没有找到原本包上应该有的金属件，但是找到了手机的主板。说明柏玲当时在玩手机，所以手机掉落在车里，而包被抢走。”韩亮补充道。 “在柏玲放弃抵抗，让凶手终于抢过手提包的时候，其实她已经因为失血过多丧失了意识。”我接着说，“因为有外裤和腿部肌肉的遮挡，血液没有大量喷溅出来，加之光线较暗，凶手并没有意识到柏玲已经即将死亡。在他们得手后，准备撤离的时候，才发现了柏玲的异常。此时，害怕事情败露的他们，只能将车辆的内饰和一些易燃的抱枕、洋娃娃什么的作为助燃物，点燃了汽车。这一点，也说明了凶手应该有前科劣迹。除了我上述的分析，没有其他作案过程可以完全解释所有的现场和尸体状况。” “确实，如果确定手提包不在车内，倒是侵财的有力证明。”赵局长认可我们的看法，“光天化日、胆大包天。不过，即便是知道有两个人，即便是查找前科人员，也未必能找到这两个凶手。而且，即便是找到了，也没有办法甄别啊。” “因为甄别这个事情，我昨晚熬了夜。”我从包里拿出几张纸，说，“我这里有DNA实验室连夜做出的DNA图谱，这两个人应该就是犯罪分子。” “你们找到了凶手的DNA？”赵局长喜出望外，“你怎么确定这就是犯罪分子的？” 我看了看专案组门口，见林涛还没有出现，于是说：“林科长从现场提取回来了七十二枚烟头。我昨天晚上用了不少时间，把这些烟头分门别类，最终找出了两枚比较特殊的烟头。这两个人的DNA就是从这两枚烟头上做出来的。” “可是你凭什么说这两枚烟头就是凶手抽的？” “首先要说一个前提，如果是侵财案件，而且有刀，就不是临时起意。而是早有预谋。然后经过预谋的抢劫，不应该在人多车多的地方作案啊。那么只有一种解释方法，就是犯罪分子年轻气盛，因为缺钱而急不可耐，只能在一个车相对少的停车场守株待兔。等到有豪车开入的时候，趁着停车的时候冲上去，抢劫。毕竟在车内，不容易引起车外人的注意。而且在人多车多的地方，也容易逃窜。他们认为，最危险的地方反而是最安全的。”我说，“既然是定点守候，那么烟头就有了它的价值。既然被逼得要去抢劫，那么抽烟的档次不会太高，这是其一；既然之前判断了有两个人，那么就应该在某个地方同时发现两枚一样品牌的香烟，并且不是一个人抽的，这是其二；选择目标是随机的，所以不可能等到一根烟抽完才动手，什么时候来车，什么时候就会立即丢掉烟头动手，这时候香烟可能刚刚点燃，也可能只抽了一半，这是其三。” “所以你就找到了符合这三条的烟头？” 我点点头，说：“我对照着当时提取烟头时拍摄的现场照片，逐一寻找，发现了两枚五块钱一包的香烟烟头，这两枚烟头都只抽了一小半，就被丢弃。被丢弃的地点也就相隔一米。于是，我把这两枚烟头作为重点，进行了DNA检验，果真，这两枚烟头不是一个人的。” “听你这么一说，还真是挺可疑的。”赵局长说，“用这种办法提取物证，我还真是闻所未闻。找到这两个人，即便不是凶手，也应该有可能是目击证人。不过，就算他们俩是凶手，抓回来拒不交代，我们还是没有物证起诉他们啊。” “毕竟案件现场条件差。”我说，“一方面是在开放式的广场，一方面中心现场遭到了焚毁。想像其他案件那样获取直接指向犯罪的物证，几乎是不可能的。” “不过，只要能形成证据链，即便是没有直接指向犯罪的证据，依旧可以证明犯罪。”赵局长说，“可是即便我们把人抓回来了，获取了口供，也确定了烟头的DNA，一样不能形成一套完整的证据锁链啊。” “那就要看林涛林科长的本事了。”我微笑着说。 在众人一脸迷惑的表情当中，我的思绪回到了昨天晚上我和林涛见面的时候。 “什么？又要我去求那个卖奢侈品的胖女人？”林涛叫道。 “为了破案嘛！又不是让你去卖身！那么激动干什么？”我说。 “这和卖身差不多了！”林涛抗议说，“你怎么就能肯定凶手把包卖了？” “就是啊，说不定顺手扔河里了呢。”大宝说。 我摇摇头，说：“那个包，至少也值个三万块钱，只要不是不识货的家伙，都会卖掉。我们之前分析凶手应该很年轻，现在的年轻人，谁不认识奢侈品品牌？” 大宝见我说他不识货，又或是被包的价值吓着了，吐了吐舌头。 林涛说：“那你怎么知道他们肯定会卖给那个胖女人？” “她们倒卖奢侈品这一行，都有她们的潜规则吧。”我说，“上次我们在她的店里看到了，有很多二手奢侈品出售，说明她也回收二手奢侈品。即便凶手没有选择离现场较近的胖女人家，我也敢打赌这个胖女人有本事探听到哪家收了赃物。” “那直接叫派出所把她传唤来问问就好了。”林涛仍然一脸不情愿。 我笑了笑，说：“传唤过来，就真的打草惊蛇了。我要你请胖女人喝杯早茶，然后拐弯抹角地探出来，我相信你有这个本事。” “我又不是地下党！”林涛说。 我盯着林涛说：“我们之前的工作，没有发现有力物证，这你也是知道的。条件这么差的案件现场，能不能拿出有力物证，在此一举了。” “就真的没有别的路子了？”林涛眼看就要屈服了。 “那个胖女人与我们这么敌对，肯定不是做什么正经生意的。如果真的是她收受赃物，我们也有义务切断这条销赃线。”我继续攻心，“没有买卖，就没有伤害。那也就不枉你的一番心血了。” 林涛烦躁地踢着脚下的一枚小石子，想了片刻，说：“好了好了，我真是服了你了。” 专案组按照我们之前的思路，对案发现场附近的、年龄较小的、有过侵财类前科劣迹的人进行了梳理，同时，尤其是注意这些人中，哪两个人近期有过紧密联系，就会提升他们的嫌疑。 其实不梳理不知道，一梳理还真是不少。经过一整天的筛查、摸底，最终锁定了12个人符合上述的条件。当然，这12个人被刑警队请回来的时候，都是清一色的冤枉脸。从面部表情来看，是无法分辨谁才是凶手的。 刑警支队的侦查员在第一时间取了这12个嫌疑人的血液，火速送往DNA实验室里进行检验，并和嫌疑烟头的DNA进行比对。 林涛还真不是盖的。一顿早茶的工夫，就直接发现了破案的线索。据说，在喝早茶的过程当中，林涛直接向胖女人表露自己想给姐姐买一款包包作为生日礼物，但是苦于工资太低、包包太贵。胖女人则微微一笑，告诉林涛自己收了一款九成新的迪奥包，可以去她店里看一看，如果喜欢的话，以市场价一折卖给林涛。 柏玲丢失的手提包，侦查员早已找到同款并拍照给林涛看过了。所以当林涛看到胖女人从一个隐蔽的保险柜里神神秘秘地拿出那款粉红色Lady Dior的时候，就已经把她定为“收购赃物罪”犯罪嫌疑人了。 获知这个消息的时候，我非常不能理解。其实这个胖女人知道这个包包是赃物，而且刚刚收回来，绝对不能顶着风头卖出去。更知道林涛就是一个警察。可是，她千算万算躲过所有人的眼睛，却老老实实地把犯罪证据交给了林涛。 这就是帅哥的力量吧。 因为奢侈品每件都有编号，所以锁定胖女人收购的这个包就是受害人柏玲的手提包是一件很容易的事情。换句话说，胖女人是否构成犯罪可以先不去细究，她却是唯一可以一眼认出卖包者的人。而这个卖包者，很有可能就是犯罪分子。 “看着吧，如果她认出的两个人的DNA，恰好和烟头上的DNA对上了，这就构成了一个完整的证据链。”我说，“在现场有逗留，反常灭烟，在起火前获得死者的随身贵重物品，而且还符合我们对犯罪分子的刻画。” 赵局长看着屋内戴着手铐的胖女人，点点头，说：“就怕她记不住啊。眼前这12个小青年，我觉得长得都差不多，可不太好分辨面容。对了，你们要做好辨认笔录，全程录像啊。” 一个爱看帅哥的女人，会对男人脸盲？I do not believe.从一开始，我对胖女人直接指认出犯罪分子就充满了信心。 当然，她也没有辜负我的期望。 因为证据确凿，胖女人为了减轻自己的罪责，只能将功赎罪。 她挪动着肥腻的身躯，站在辨认窗的后面，努力地看着辨认间里的12个小青年。 “1号和7号。”她说。 我看见两名侦查员对视了一下，露出了胜利在望的表情。从他们的表情当中，我读懂了一条信息：很显然，这两个嫌疑人之间恰好有着紧密的联系。 “不用再看一遍了？确定吗？”侦查员例行公事地问。 “不用了，我确定。”胖女人已经收起了她之前面对我们时的锋芒。 “那就在这里签字吧。”侦查员说。 第二天一早，DNA比对吻合、案件获得侦破的时候，我们又踏上了出勘现场的路途。 虽然市局给省厅上报的是“环城公园某灌木丛中发现一具无名女尸”，并没有明确案件性质和特点，只是在内容里提到了该女子衣衫褴褛，怀疑是流浪女。 这看似是起流浪女非正常死亡的事件，却引起了我的警觉。毕竟，之前那具无名高腐女尸是否和杜洲失踪案有关，一直还充斥着我的脑袋。 环城公园是个奇妙的地方。因为绿化植被较好，又有很多石桌石椅，所以成了很多老年人消遣的好地方。每天早上六点开始，这里就有很多老年人，喝茶的喝茶、遛狗的遛狗、打牌的打牌。但是到了晚上八点以后，这里可以说是一个人迹罕至的地方。昼夜对比异常分明。 “看市局报的情况，应该和我们分析的几乎丝毫不差啊。”林涛坐在摇晃的警车里，拿着几张《公安机关内部信息传真》说，“蹲守，随机寻找目标，直接拉车门上车实施抢劫。因为柏玲激烈反抗，抓着包包坚决不撒手，所以两个人才用了勒颈、刺腿的办法。抢到包的时候，发现柏玲已经没有了意识，所以凶手就点燃了车内的一些易燃的装饰物和坐垫。自始至终凶手都没注意到放在操作台上的警帽，所以也不是寻仇之类的。其实挺简单的作案过程，差一点就把侦办工作变复杂了。” “尊重客观现象，才能永远不绕弯路。”我说，“看来到了，有人围观嘛。” 我们刚刚走下车，当天值班的但法医就朝我们迎面走了过来，说：“比想象中复杂多了，死者身上有伤啊！” “能确定是命案吗？”我慌忙问道。 但法医左右看看，见在警戒带外面聊的话，有可能会透露侦查秘密，所以把我们拉近了警戒带，走到尸体旁边说：“周围程子砚都看了，因为都是普通的土地，也没有留下什么明显的足迹，所以暂时也不知道她是自己走到这里来的，还是别人抛尸来这里的。但是你看看，这个女人的后脑勺感觉都碎了。” 但法医蹲下身去，双手抱起死者的头颅，按了按。别说但法医自己，连一米开外的我，都可以听见明确的骨擦音。 “颅骨骨折？”我问。 但法医点点头，说：“但是头皮上只有皮下出血，而表面没有擦伤。说明她的后脑是和一个表面很光滑的物体作用形成的损伤。” “对。不论是摔的，还是打的，致伤物体都应该是光滑、坚硬的物体。”我说，“可是这里最光滑的就是这些石头凳子了，也是水泥的，表面也很粗糙，有点不太符合。” 但法医又把死者的衣服掀开，说：“你们看，死者的后背部，有几处擦伤。我看了，擦伤表面还有一些小的竹刺。像是被破旧的竹子刮的。这里又没有竹子！” “不仅如此。”我补充道，“死者穿着衣服，衣服上没有伤，而竹刺越过衣服直接扎到了皮肤里，这也没法解释。” “看来死者是光着身子遭受侵害的，死亡后，被人穿了衣服然后抛到了这里。”大宝总结了一下。 “死者身上还有很多其他损伤啊。”我戴上手套，蹲下身，拿起死者的手腕。 尸体的尸斑已经完全形成了，尸僵也很坚硬，可以肯定是在昨天下午到晚上时分死亡的。如果按照死亡后17小时尸僵最硬的理论，她应该是昨天下午四点钟左右死亡的。而那个时候，这个公园到处都是老年人的身影。不仅如此，死者身上尤其是手腕部，都存在明显的约束性损伤。看起来，这是一起命案无疑了。 可是但法医的发现仍然没有介绍完。 他说：“还有一个点，就是死者死亡前存在呕吐行为。” 说完，但法医用止血钳拉开死者的口腔。从死者牙缝之间和颊黏膜上都可以看到有很多食物残渣黏附。 “颅脑损伤，通常有呕吐。”大宝说。 “可是现场附近并没有找到死者的呕吐物。”但法医说，“这也是死后抛尸的一个有力证据。” 我点了点头，说：“既然现场没什么，那就抓紧检验尸体吧。我们先走一步，解剖室会合。” “刚才看尸体，你们有什么看法没有？”我说。 “女孩很年轻。”林涛说。 “皮肤保养得很好。”陈诗羽更了解女人。 “那么就不可能是流浪女了。”大宝又做了个总结
