Chapter 4 The third case Hulk

"River Drift", "Sea Drift" and "Road Down" respectively represent unidentified corpses found in the river, sea and roadside.Forensic doctors in every city can see dozens of such corpses every year. For more than half a month, nothing happened, and the sky began to heat up. During this time, all five of us subconsciously kept our mouths shut about the last shooting.Zhang Yue's tearful eyes made us feel sympathetic and even a little guilty.It is our duty to find out the truth, and the truth brought prison to that poor man.Guilt to guilt, deep down we all know there is nothing wrong with doing it for the truth.Just like the law of "no doubt", it seems to protect criminals, but it is actually protecting the legitimate rights and interests of every citizen.But having said that, the heart of a forensic doctor is also fleshy, and it still takes a process to get out of the trough.

Perhaps it is the shared sorrow that gives our small group more reasons to work hard to create joy.After work, we would call Ling Dang, Bao Sao, and Han Liang's constantly changing girlfriends out for a party.The difference from before is that now we have an extra recorder in our party, and every happy moment will be captured by the camera lens of "professional photographer" Chen Shiyu.As time goes by, we become more and more accustomed to Chen Shiyu's existence.Although in the days when we are not on a business trip, the heavy administrative work is as overwhelming as the review of letters and visits, but in the interval between dealing with trivial matters, we all searched our stomachs and found some jokes to amuse each other, which made us survey a group during this time. It was full of laughter and laughter.Even Chen Shiyu, who doesn't talk much, will take the initiative to join the ranks of telling jokes.

To be honest, if it is not reluctant to let Bell with a big belly endure loneliness, I really prefer the days of business trips.Because when handling a case outside, you only need to concentrate on the case, but when you work in the office, there are so many trivial matters, but you often feel that your brain is not enough. On this day, Lin Tao was flipping through a copy of "Forensic Psychiatry" in our office. "You forensic doctors also want to study neuropathy?" Chen Shiyu asked curiously. "Feather, I have to educate you about this, so as not to embarrass us in the future." Dabao said, "Psychiatric identification is also a branch of forensic identification."

"The one talking about full responsibility, limited responsibility and no responsibility?" Chen Shiyu continued to ask.This time she didn't correct the mistake in Dabao's address, she might have gotten used to it. Dabao nodded. Lin Tao said: "I have seen a movie called "Yasha" before. It said that many appraisers cheated and judged those rich people who committed crimes as irresponsible, and finally they were not held criminally responsible. A policeman can't understand it. , just use the night time to flog and kill these bad guys, it’s very enjoyable to watch. Don’t cheat when you do the appraisal, so as not to be flogged and killed.”

Dabao snorted and said, "Lin Tao is right. I think those who should be killed most are these fake appraisers, who are worse than criminals. However, the forensic doctors of our public security organs don't do psychiatric appraisals. It is of great importance, and it needs to be appraised by an appraisal committee composed of experts from psychiatric hospitals with qualifications for psychiatric appraisal. This can be regarded as a guarantee of the authenticity and objectivity of the appraisal." Chen Shiyu asked: "Among the cases you have participated in, are there many murder cases involving mental illness?"

Dabao thought for a while and said, "Well, there are quite a few, and such cases are not easy to solve, hard to find evidence, and don't expect to have a confession. But Lao Qin, do you remember? We once killed a mentally handicapped person. In the case of a husband and wife, it was judged through behavioral analysis based on the excess damage on the body that the murderer was mentally insane." "Wait," I interrupted while writing a report, "Let me correct a mistake made by Chen Shiyu." "You keep talking about mental illness, but what you mean is mental illness." I said as I wrote.In my opinion, writing a report is the least brain-intensive thing. It has a fixed format, fixed title, and fixed content. "In medicine, neurosis and mental illness are two different concepts. Mental illness refers to a serious psychological disorder. The patient's cognition, emotion, will, action and behavior may have persistent and obvious abnormalities, and he cannot study and work normally. , life, and action behavior are difficult for ordinary people to understand. Under the domination of morbid psychology, mental patients will commit suicide or attack or hurt others. Neuropathy refers to organic diseases of the nervous system. Although both Time can coexist, but they are indeed two different concepts.”

"Oh." Chen Shiyu was thoughtful, "Psychiatric diseases are managed by psychiatric hospitals, and they can be evaluated for mental illness. What about neuropathy? Who is in charge of neuropathy? Can they be evaluated?" "If it is a neuropathy caused by trauma, we will conduct forensic identification of the degree of human injury." I said, "The treatment will be under the supervision of the neurologist in the hospital." "Go, go, what is it?" Dabao suddenly turned his face, "I won't break up with you." A few of us were at a loss.

"What's the matter?" I changed my mind, Dabao's wife seemed to be a doctor of neurology, and then said, "Did you hear wrong? I didn't say that doctors of neurology are bad. I'm just giving Chen Shiyu a popular science , Neuropathy is under the care of neurologists, that’s right.” Dabao looked up at us for a moment, then lowered his head, rubbed the hem of his clothes and said, "Hmph, my wife will take care of me." While we were laughing, the phone rang suddenly. "Why, have you been too busy recently?" Master's voice said, "Smile so happily?"

It must be when I answered the phone, Lin Tao still couldn't hold back his laughter.I gave Lin Tao a blank look, and Lin Tao stuck out his tongue. "Is there a job?" I quickly changed the subject. "Fengling City. There is a factory, and there is a river drifter in the small river at the entrance. Now the local forensic doctor is not sure about the nature of the case. I want you to go and have a look." Master said. "River Drift", "Sea Drift" and "Road Down" respectively represent unidentified corpses found in the river, sea and roadside.Forensic doctors in every city can see dozens of such corpses every year.In order to express concisely, we adopted such a way that can be understood and conveyed easily.

"The river... the river drifting?" I looked out the window, the sun was shining brightly, and I pinched my nose at Dabao and Lin Tao. Dabao quickly got up and opened the cabinet, and found the gas masks for the three of us. "This case is not in a hurry." Master said, "It was discovered yesterday morning. The local forensic doctor conducted an autopsy yesterday afternoon. Today they discussed and disagreed, so they asked us for help. You just need to arrive before lunch." I raised my wrist to look at my watch, thinking this is not in a hurry?It's past nine o'clock now, and Fengling City is still more than 200 kilometers away from the provincial capital. Isn't it urgent?

Not daring to talk nonsense, the five of us drove off with the survey box in hand. Fengling City is a small city on the banks of the Yangtze River. Although it is located at the junction of three provinces, its population is small and its life is rich. Therefore, vicious murders are extremely rare.I have been working all these years, and I have never been to Fengling City on business. After the car drove off the highway, it crossed the entire urban area. We admired the scenery of this small town with beautiful mountains and rivers all the way, and we wondered what kind of case this time would be and how corrupt the corpse would be.Only Chen Shiyu was still in the mood to keep taking pictures through the car window. The corruption of the corpse will lead to the loss of some reasoning conditions and a lot of evidence, which will not only bring great difficulties to forensic work, but also add a lot of risks to forensic inference.Of course, this is also the first time Chen Shiyu has come into contact with a corrupt corpse, so I really want to see if she can pass this test. Under the guidance of the local police car, the bustling noise outside the window gradually disappeared, and the vehicle drove into the economic development zone on the outskirts of the city.The population of the small town is very sparse, and this area is even more inaccessible.The police car flashed its lights and drove to the gate of a factory in a short while. "This is a pillar enterprise in our city, with thousands of employees." Captain Zhao of the Criminal Police Detachment of the Municipal Bureau jumped out of the car and said to us, "There is a living area in this large factory area. On weekdays, the workers Almost all of them live in the factory area, and only go home on weekends.” I looked around my surroundings and asked, "Is the transportation here convenient?" Captain Zhao shook his head and said, "If you don't have transportation, you can only walk 500 meters to a bus stop over there and take a bus to the city. Most of the employees in the factory here have their own private cars. For those who don’t have a car, the factory will arrange a shuttle bus to pick them up on weekends and Mondays.” "Is the scene here?" I saw a small river in front of the gate of the factory, with gurgling water and crystal clear water.This small river is like a moat, surrounding the entire factory area, and only a few entrance gates have wide bridges for people to enter and exit.Our vehicle was parked on a wide bridge, looking over the river bed, one or two blue disposable surgical gowns and a few pairs of latex gloves were particularly eye-catching. I frowned and shook my head, thinking that now the province pays so much attention to the management of survey waste, but you haven't implemented it at all here.Surgical gowns and latex gloves are hard-to-degrade substances, which will pollute the environment and affect the image of the city.Therefore, the provincial department requires police officers from all over the country to collect the survey garbage in a unified manner after the on-site survey is completed, and deal with it in a centralized manner. Captain Zhao nodded and said, "There is usually no one here at the gate. On Monday, when the employees went to work, someone found a foreign object under the bridge. The factory security went down to the bottom of the bridge and found a dead body, so they reported it. " "Then the time for committing the crime is the weekend?" Dabao asked. I shook my head and said, "No, I heard that the corpse was highly decomposed, so it certainly wouldn't be within two or three days. The corpse floated up after decomposing, and the river was flowing, but the corpse floated to the bottom of the bridge. , was blocked by the bridge piers, it was discovered here, I think the place where the body was dumped must not be here." Captain Zhao nodded and said, "Indeed, we have checked all the monitors of several gates of the factory, and found nothing." We walked across the Broad Bridge and walked a part along the factory wall.Chen Shiyu said: "I see that there is a surveillance camera on the wall of the factory every few hundred meters?" Captain Zhao said: "Yes, in fact, from outsiders, there are many surveillance cameras around the factory area, which should not be a good place to dump corpses, but everyone in the factory security department knows that these surveillance cameras can only monitor the area above the wall, the river bank, etc. The situation on the opposite side cannot be seen, that is to say, throwing the body across the river bank cannot be recorded by surveillance cameras." "Are you suspicious of someone from the security department?" Chen Shiyu asked. Captain Zhao did not speak. I went on to say: "I won't talk about the surveillance cameras in the factory area, but the surrounding area is wilderness, and it is easy to find a place to bury it. Why do you have to throw it in the river? Although the surveillance cameras can only see the top of the wall , but throwing the body against the edge of the blind spot of the surveillance camera is also a very risky thing. Even the security guards who understand the surveillance cameras in the factory area would not take this risk according to common sense." Captain Zhao interrupted my thinking and said, "Why don't we eat first, and don't be preconceived, because some of our forensic doctors think this is just a suicide or an accident." Dabao patted his head and said, "That's right, we are here to help guide the case's characterization, why are we preconceived so quickly?" Forensic doctors are also human beings. It would be a lie to say that there is no discomfort at all under the dual stimulation of vision and smell when seeing a decaying corpse.I remember that many forensic doctors said that if I had rhinitis, it would be fine, and I would not smell bad.In fact, rhinitis and pharyngitis often exist together, and the symptoms of pharyngitis often include nausea and retching.For a forensic doctor with pharyngitis, it is not easy to suppress the feeling of retching during the on-site investigation of a corrupt corpse.I am.As a forensic doctor, retching at the scene is a shameful thing after all, and it will inevitably make the leaders question your ability to work.Therefore, for an investigation student like Chen Shiyu who was exposed to corrupt corpses for the first time, I can understand even if she vomits out of shape. As soon as I jumped out of the car at the door of the forensic autopsy room of the funeral home in Fengling City, I smelled that familiar and disgusting smell.In the dissecting room equipped with complete exhaust facilities, one can imagine what it would be like to be able to withstand the limelight and stinky corpses. In the dressing room, through the row of glass, only a bulging body bag can be seen on the dissecting table.We know that this is not because the deceased is too fat, but because the concept of giant has been formed.The so-called giant concept means that after the corpse is highly decomposed, it will be affected by the decaying bacteria, and a large amount of gas will be produced in the body, which will gradually spread to the whole body, making it look like a giant.At this time, the epidermis of the body is moist and easy to fall off. The eyeballs and tongue will swell due to swelling, and the appearance will be lost. After seeing the photos of the giant view on the Internet, many friends will receive a strong visual impact and lament the difficulty of forensic medicine.In fact, it's nothing if it's just visual impact, what's more terrible is the sense of smell and touch.Needless to say the stench, the tactile sensation when examining a dead body is also very uncomfortable.Because the whole body of the giant-looking corpse is wet, the epidermis will fall off with a little force, so it is very difficult for the forensic doctor wearing latex gloves to even grasp the limbs of the corpse, let alone turn the corpse over. However, in order to find the truth and give justice to the deceased, all these sufferings are worth it. We dressed quickly and went into the dissecting room.Zhou Zhi, chief of the forensic department of the Fengling City Public Security Bureau, slowly opened the body bag, exposing a dark green corpse of a giant.Followed by it, there was a pungent stench. I turned my head to look at Chen Shiyu, she was obviously also smoked, and couldn't help wrinkling her nose.But the first time I faced such a scene, she didn't show any signs of vomiting, which surprised me a lot. With the assistance of advanced instruments, forensic doctors bid farewell to the era of dog noses.In the past, we relied on wearing masks to block some bad odors. Now that the conditions are better, forensic doctors will be equipped with gas masks to prevent the poisonous gas produced by rotting corpses from invading the body of forensic doctors.The activated carbon cartridge in the gas mask can indeed absorb some toxic gases, but its ability to block odors is not much higher than that of masks.At this time, the stench passed through the gas mask and got into our nostrils.I frowned, wearing this thing, I can't even do the habitual movement of rubbing my nose. The corpse stuck out its tongue and stared at us. "Oh my God!" Seeing the face of the corpse, Chen Shiyu finally couldn't help exclaiming. It is true that this corpse of the Colossus view is extremely inflated, which is relatively rare. "Hulk, this is it." Dabao said. Due to the progress of corruption, the tongue of the corpse had turned dark green, protruding eeriely from the mouth.The skin on the face became very tight due to gas expansion, the eyelids were stretched into a line, and the half-collapsed eyeballs were exposed outside the eye sockets, as if they were about to fall off at any time.The corpse's clothes had already been cut and removed during the initial inspection, and forensic doctor Liu of the Fengling City Public Security Bureau was putting the clothes together and restoring them one by one on the operating table in a corner of the dissection room. The deceased was a male of unknown age.The chest and abdomen of the corpse were raised high, and the whole body was dark green, with intricate black and red veins in between.All the hair fell off, and the skin on the soles of the hands and feet was wrinkled and deformed, and the skin could be completely peeled off with just a gentle tug. "The corpse hasn't been dissected yet?" I saw that the surface of the corpse was complete and there were no sutures, so I asked. Section Chief Zhou nodded and said: "We have a lot of controversy over the head and face injuries of the deceased. We have decided not to conduct an autopsy for the time being. We will discuss it together when you come." "Where's the corpse source?" I asked. "The DNA has been taken and sent to the laboratory, and the results are probably out now." Section Chief Zhou said, "But because there is no autopsy yet, there is no way to describe the characteristics of the corpse. Is it a local, is it? None of the residents around the scene can be confirmed. The investigation of the missing persons is ongoing." "Didn't your fingerprints be taken?" Lin Tao said in a low voice while wearing a mask. Generally, the fingers of corpses that have undergone the initial autopsy are black, because routine fingerprinting of corpses is required.It is to smear ink on the fingertips of the corpse, and then print on the fingerprint card.The obtained fingerprints can be used as a basis for finding the source of corpses and excluding on-site fingerprints.For corpses that are highly corrupt and not necessarily homicides, the requirements in this regard are not very strict. Section Chief Zhou shook his head and said, "The skin of the deceased's fingers could not be stamped due to corruption and long-term soaking in water." "Who says it's impossible to make a seal?" Dabao carefully took the hand of the deceased, looked at it, and said, "It's so good to make a seal." After Dabao finished speaking, he scratched the base of the deceased's right thumb with a scalpel, and then took off the skin of the thumb as if taking off a glove, and then carefully inserted his fingers into the skin cover , said: "Get the stamping card quickly!" In this way, Dabao took off the skins of the ten fingers of the deceased one by one, put them on his own fingers, and completed the imprint of the deceased's fingerprints.Chen Shiyu was dumbfounded. This method of fingerprinting is not routine, but we use it quite often.Fengling City is a stable and harmonious small city. There are not many murder cases, and murder cases of corrupt corpses are even rarer.So the local forensic doctor did not learn this kind of creepy method. Of course, this approach does not work every time.If the degree of corruption of the corpse has not reached the peeling of the hand skin like a glove, or the degree of corruption is so severe that the skin of the fingers has been broken, this method cannot be used for fingerprint printing.Therefore, in this case, Dabao successfully obtained the ten fingerprints of the deceased, and there was also an element of luck in it. "What are you arguing about?" I didn't watch Dabao's process of taking fingerprints, but concentrated on looking at the several interlaced wounds on the face of the deceased.After all, whether or not fingerprints can be obtained is not the key to the accuracy of a case. The facial skull of the deceased did not collapse, and there was no obvious bone fricative sound when pressed with finger pressure. It can be seen that there was no obvious serious fracture.However, on the dark green face, several skin clefts with irregular edges and intersecting each other can be seen.Because of the high degree of corruption, the area around the wound has become unclear and blunt, and it is impossible to judge the instrument of injury, let alone judge whether there is a living reaction. "It is impossible to judge whether there is a living reaction or not." Section Chief Zhou said, "Other than that, no fatal damage was found on the body of the corpse. The poison test was also done, and there was no sign of poisoning. So it is not easy to confirm that the deceased died of drowning. , or thrown into the water after being beaten to death. The corpse is so corrupted that we are worried that we will not be able to confirm it after an autopsy, so we will wait for you to come." "It's really hard to see if there is any life reaction." I held my breath, looked at the wound with a magnifying glass, and said, looking closer at the wound. Section Chief Zhou said: "The Huanchang River at the scene is connected to the Fenghe River, the mother river of our Fengling City, and there are many fish in it. Therefore, some people think that this is the wound caused by being eaten by fish after death. , otherwise how could there be so many wounds, but the lower skull is not fractured? However, some people think that fish are not beasts after all, so they cannot eat so many and such big wounds." All forensic doctors know that corpses in the wild may be eaten by wild animals, but not all forensic doctors know that the eating of fish can also form wounds on decayed corpses. I once visited a scene. After the forensic doctor fished out a corpse from the river, he found a skin defect in the middle of his forehead, and a crack was seen on the skull below the skin defect. Anyone who has studied the basics of medicine knows that there is a horizontal and a longitudinal bone suture on the top of the human skull, which are called the coronal suture and the sagittal suture respectively.In addition, there is a "human" bone suture in the occiput, which is called herringbone suture.Other than that, the skull should be complete and smooth, and there should be no cracks.Since there should be no bone seams in the forehead normally, the crack found should be the fracture line.The forensic doctor infers that this may be a murder case. The murderer hit the deceased's forehead with a blunt instrument, resulting in a skull fracture and brain contusion and death.When the family members were notified that an autopsy would be performed, the family members unanimously opposed it.Because the family members knew that the deceased suffered from depression and failed to commit suicide many times, before leaving home this time, he also wrote a suicide note saying that he would commit suicide by throwing himself into the river. The forensic doctor felt that the family members' opposition to the autopsy was a bit strange, so he asked the investigation department to investigate the family members of the deceased, and obtained the consent of the director to forcibly dissect the body.After the autopsy, I didn't know how to draw a conclusion, so I applied for support from the Ministry of Finance. After we arrived at the scene, we conducted a re-examination of the body and found that the cracks under the skin defect on the forehead of the deceased were tortuous, obviously not fracture lines, but bone seams.This involves unpopular knowledge.In fact, in every six hundred people, there will be one person with this kind of congenital variation. There is a bony suture in the middle of the frontal bone that has not healed well, which is called "congenital non-healing frontal suture".In forensic autopsies, people with congenital non-healing frontal sutures can often be found, but as long as the skull is not damaged, forensic doctors sometimes do not notice abnormal bony sutures in the forehead. Later, the case was classified as a suicide case.Because after the corpse was decomposed, the forehead was eaten by fish, resulting in skin defects, which happened to reveal its congenitally mutated bone seams, which caused misunderstandings by forensic doctors. "It really doesn't look like it was eaten by a fish." I frowned and said. "It's definitely not a sharp wound, because the edges are not neat." Chief Zhou said, "But if it was a blunt wound, so many wounds must have been hit, so wouldn't the lower skull be fractured?" "Let's do an autopsy." I said, "Section Chief Zhou and I examine the head and face, and Dabao and Forensic Doctor Liu examine the chest and abdomen." Before I finished my words, Dabao's scalpel was cut down.When the abdominal cavity of the corpse was cut open, there was only a "pop" sound, and the distension of the corpse's abdomen quickly disappeared.I quickly held my breath, waved, and signaled us to leave the dissection room temporarily.Unexpectedly, Lin Tao was faster than me, and he had already dragged Chen Shiyu to hide behind the partition glass in the dressing room. Walking into the locker room, I said, "Dabao, can you say something before you go under the knife?" Dabao laughed and said: "Then I can't shout, get ready, row!" "A large amount of gas has accumulated in this corpse. Once there is a breach in the corpse, the gas will rush out from the breach. First, the smell is unbearable; second, it will release a lot of toxic gas, which is harmful to health. Unfavorable; third, this is the same principle as an explosion, the gas will carry the corrupt liquid in the body and splash out.” I said, “Dabao, don’t you need to wash your clothes yourself?” A few of us hid behind the isolation glass in the dressing room and watched the corpse gradually "thin".Section Chief Zhou turned up the exhaust system to the maximum air volume.After five minutes, we returned to the dissecting table and started working. The soft tissue of the corpse was already very loose due to corruption, and the place where the scalpel was cut was immediately divided into two, exposing the same dark green subcutaneous tissue.Holding a scalpel, I cut open the facial skin of the deceased along the direction of the mandible, and then gradually separated it toward the nasal bone.Chief Zhou also dissected the other side of the deceased in the same way as I did. "The green color of the subcutaneous tissue of the deceased's face is darker, indicating that there was once blood gathering here." I said, "The blood seeped from the blood vessels to the soft tissue, indicating that the blood vessels here were ruptured." "You mean it was an injury during his lifetime?" Section Chief Zhou asked. I nodded and said: "There is no sufficient basis, but based on experience, I think there is something abnormal here." While talking, we have lifted off the facial skin of the corpse, exposing the facial skull.This "skeleton", which is still connected to the body, has a scalp and ears, looks particularly terrifying. I touched the nasal bone of the corpse and said, "Ah, the nasal bone is broken." The soft tissue near the nasal bone of the corpse was carefully separated, and fragments of the nasal bone were exposed.The nasal bone is the most vulnerable bone in the facial skull.Because the nasal bone is more protruding than the facial skull and is very thin, when the face is injured, the nasal bone is most likely to be fractured. I used a hemostat to clamp out the fractured fragments, observed it under a microscope, and said: "There is blood seeping into the bone at the broken end of the fracture!" Due to the effect of corruption, the blood will gradually turn into a putrid liquid, making it impossible to judge whether the corpse is bleeding or not.But the blood seeps into the broken ends of the bones before the corpse decays, and will be preserved between the trabecular bones.Through this, it is certain that the deceased suffered a nasal bone fracture before his death. "The facial skin was contused and the nasal bone was comminuted, but the skull was not fractured. Is this because the murderer was weak or because the tool was light?" said Chief Zhou. "Obviously because the tools are light." I said, "If the tools were heavy and the murderer's strength was so weak that he could only fracture the nasal bone, then it would be impossible to form so many contusions on the facial skin. Only when the tools are light, Although the murderer beat hard, he could only break the skin and shatter the nasal bone, but could not damage the solid skull." "Tools are lighter..." Section Chief Zhou pondered. I said: "The skin of the deceased's face is blunt and irregular around the cut, which means that the tool has no sharp edges and should be a smooth tool. Because it is lighter, it must not be metal. In addition, the reason why it can form irregular The wound, the contact surface of the tool must not be a flat or curved surface, but should have smooth strip-like protrusions." Lin Tao rolled his eyes aside: "What could that be?" "I don't know." I shook my head and said, "But at least it's not a sharp weapon for killing. Why did the murderer choose such a tool to kill people? Isn't this asking for trouble for himself?" "It's hard to say whether the facial injury is fatal." Chief Zhou said, "Let's have a craniotomy." Amidst the roar of the craniotomy saw, Dabao suddenly screamed sharply: "The upper corner of the deceased's thyroid cartilage was fractured!" The thyroid cartilage is a square-shaped piece of cartilage in the front of the neck, one on the left and one on the left, joined together at the very front of the neck.The upper corner of the thyroid cartilage is located on both sides of the middle of the neck.Although the skin on the neck of the corpse has been corrupted, and the skin damage cannot be seen, but from the fracture of the cartilage, it can be judged that the neck of the deceased suffered violence during his lifetime.Because there were fractures on both sides, such violence must have been caused by strangulation.Of course, strangulation can also form such a fracture, but it will definitely leave a cord groove in the neck, which is not here. "Strangle?" I stopped the saw and said, "Does the body show signs of asphyxiation?" Dabao shook his head and said, "The eyeballs are protruding, and we can see that there is no bleeding point. When we performed the chest and abdomen examination just now, we did not find any bleeding points or signs of congestion in the major organs of the deceased." "There was a choking motion, but it was not mechanical suffocation." Section Chief Zhou said, "What does that mean?" "Hehe." I smiled, continued to turn on the craniotomy saw, and said, "It means that the choking action is just a restrictive action. It's very simple. The murderer used one hand to strangle the neck of the deceased to prevent him from moving." With the staggered saw wires, the skull of the corpse fell off, exposing the pink dura mater. After the body dies, the tissue cells lose their vital functions. Due to the action of enzymes, tissue dissolution occurs, that is, autolysis.Brain tissue is the first and most prone to autolysis, so after we cut the dura mater, a lump of brain tissue flowed out like batter. "Hurry up, take pictures and record videos!" I said to Lin Tao while catching the outflowing brain tissue with my cranium. "We can see that the color of the frontal brain tissue is much darker than that of other parts of the brain tissue." I said, "After the normal brain tissue is autolyzed, it appears light pink, but the frontal brain tissue is dark brown. It means that there was a lot of bleeding in this area before." "It's really a murder!" Dabao clamped the stomach tissue of the corpse with a hemostat with one hand, and scooped out a spoonful of stomach contents with a spoon with the other hand, saying, "There is no drowning in the stomach of the deceased!" No obvious signs of suffocation were found in the deceased, and there was no drowning in the stomach, so even if the internal organs were corrupt, it can be judged that the cause of death was not drowning.In other words, he must have been thrown into the water after his death.Combined with the contusion wound on the face of the deceased and the hemorrhage in the brain tissue, it can be judged that the deceased was repeatedly hit on the face with a blunt instrument, resulting in contusion and bleeding of the brain tissue and death. "Unbelievable." I said in a low voice, "Usually severe traumatic brain injuries lead to death due to severe head and face injuries and fractures. However, the deceased's skull was not fractured, and the tool we deduced just now is also a relatively light tool." , There is only one explanation for this, that is, the murderer took an uncomfortable and light tool and repeatedly hit the face of the deceased with great force. Because it was the face rather than the head, the transmission of the force would be weakened, and this would cause this A craniocerebral injury of a certain degree must result in frequent multiple blows, possibly dozens or even hundreds of blows." "What does this mean?" Lin Tao asked. I shake my head. Dabao said, "A deep hatred? A premeditated crime?" "No." Section Chief Zhou said, "How can you plan to commit a crime, but bring a tool that is not convenient?" "Yes." I thought for a while, and said, "What kind of thing is this rounded, lightweight tool? Is it prepared in advance? Or is it carried around?" "Even if it's a crime of passion, you shouldn't hit the face with the tools you carry with you." Section Chief Zhou said, "It takes so many hits to kill people in the face. What a waste of time. Even if you pick up a brick from the side of the road , patting the head is much easier than this." "Indeed, it's unreasonable." I said, "We don't have any clues. Let's look for some characteristics on the corpse first, and find the source of the corpse." "Well, after all, it's a corpse throwing case, and it tends to be committed by acquaintances." Section Chief Zhou said, "Look for the source of the corpse first, and the case can be solved if there is no certainty." "Dabao, go and sift the contents of the stomach to see what the deceased ate before he was alive." I said, "Let's check the age and height of the deceased." Screening of gastric contents is important.Because after the food enters the stomach for digestion, it will become chyme.The chyme is fused together, and the food form cannot be judged.The coroner will place the contents of the stomach on a sieve and rinse with water.The chyme-like object will be washed away by water, leaving some crude fiber in a form that is not easily digested, so as to judge the last meal of the deceased.But the job is tough, with the disgusting stomach contents and pungent smells a strong sensory stimulus for forensics.Especially when you eat, think of the contents of your stomach, you can imagine whether you still have appetite. Because the perineum of the deceased had been completely decomposed, we easily sawed off the pubic symphysis of the deceased and boiled it in a cooking pot. In this way, the soft tissue can be easily removed to expose the characteristic surface of the bone. After we observed the characteristics of the pubic symphysis and determined that the deceased was about fifty years old, we found Dabao holding a sieve in one hand and a spoon in the other, dazed in front of the pool. "Well, do you see what he ate?" I asked. Dabao turned around with a blank face: "No, this... this... nothing can be screened out." It turned out that the contents of the stomach of the deceased disappeared as soon as it was washed by water. Dabao sifted for an hour or two, but hardly found anything that could be used as a basis for judgment. "It's nothing strange." I looked at Dabao's cute expression and smiled, "It means that the deceased only ate pasta, such as steamed buns, gnocchi, etc., and did not eat any meat, vegetables, or fruits." "It's so hard." Dabao said. I nodded and said, "This tells us that the standard of living of the dead was low." After finishing speaking, I seemed to think of something, and said, "Have the deceased's clothes been tidied up?" The clothes were neatly placed on the operating table in a corner of the dissecting room by Forensic Doctor Liu, and the original cut ends were all closed together.I went to the console, looked at it, and said: "The deceased was wearing an old advertising shirt on his upper body, a pair of very old cloth pants on his lower body, and blue canvas underwear. These can also be judged: The dead are poor." After I finished speaking, I turned out the pocket of the deceased's trousers and said, "There are more than 40 yuan in it, and the pocket must not have been rummaged through." "Yes, the murderer repeatedly hit the deceased's face, causing the facial skin to rupture and bleed. There must be blood stains on his hands. If he rummages through the deceased's pockets at this time, he will definitely leave wipe-like blood stains on the inside of the pockets," Dabao said. . I said: "The victim is a poor middle-aged and elderly man, and there is no sign of property infringement, which shows that this case is a murder case. It may be a vendetta, but I am more inclined to kill with passion." "Is it because the tools are not handy?" Chief Zhou asked. 我点点头，说：“为什么用轻质工具，为什么打击面部，为什么不去旷野抛尸反而抛在可能被监控摄像头拍到的小河里，这都是问题，我一时还想不明白。现在只有寄希望于侦查部门，但愿他们通过我们提供的死者生活环境、体态特征可以迅速找到尸源。” “我觉得希望很大。”周科长说，“厂区附近只有一些散户居住，但他们都因为拆迁变得有钱了。要说生活条件艰苦的住户，就只有一些拾荒者了，他们都住在附近的一些破房子里。如果死者是拾荒者，肯定很快可以找到的。” 我期盼地点了点头。 说话间，林涛走出解剖室外，摘下防毒面具接了个电话，一会儿又返了回来：“云泰市发生了一起命案，现在初步勘查，还没有结果，请求省厅支援。” 我看看面前的解剖台：“我们这不是正忙着吗？肖兵他们组有空吗？” 林涛摇摇头：“肖法医他们组去洋宫了，一个信访事项的核查。” 我说：“那我们也是分身乏术啊，总不能把峰岭这个案子丢了吧。” 林涛说：“云泰市发生的，是一起流浪汉被杀案。” 我叹气：“最近还真是邪门儿了，被害的怎么都是弱势群体？你看那个'清道夫'的案子，凶手杀的就是智障人员，这一起，死者又很有可能是拾荒者，怎么云泰市也发生了类似的案子？” “咳咳。”林涛眯着眼睛，说，“峰岭市的这一起案件和'清道夫'案件显然关系不大，但是云泰市的那起案子，可和'清道夫'案件很有关系了。” “哦？”我立马来了精神，说，“什么关系？” “因为云泰市的那起，凶手也在墙上用死者的血迹写了'清道夫'三个字。”林涛轻描淡写地说道。 我一蹦三尺高。 一起半个多月未破、丝毫线索都没有发现的案件，简直太让人牵肠挂肚了。这时候凶手又犯了一起案件，势必留下一些新的线索，也就意味着这可能为案件的侦破带来了一丝曙光。 “收拾东西，赶紧去云泰。”我说。 云泰距离峰岭不远，只有六十多公里的路程。 “你刚才不还说自己分身乏术，不能丢下手上的案子不管吗？”林涛嘲笑道。 我脱下解剖服和手套，看了一眼周科长，挠了挠脑袋，尴尬地说：“这起案件不还需要时间找尸源吗？我们先去云泰穿插着多干点儿活，也贯彻了全心全意为人民服务的宗旨嘛。” 周科长被我逗乐了，笑着说：“你们赶紧过去吧，尸检的收尾工作，交给我们好了。” 尸臭的黏附能力非常强，加之夏天汗液的分泌蒸发，虽然我们闻不到自己身上的味道，但是对外面的人来说，我们已然成了臭味发散体。为了不把没进解剖室的韩亮给熏倒，我们四人匆匆回到宾馆，洗了个澡，又把衣服换洗了，装进塑料袋里，下楼乘车出发。 整个解剖过程，陈诗羽只干呕过两次。她的表现，让我对自己曾有过的性别歧视，感到愧疚和自责。 警车拉着警报，没多久就赶到了云泰市。 我对云泰还是很熟悉的，问到了现场的具体地址后，就引导韩亮直接把车开到了位于云泰市某偏僻批发市场的一个角落里。 这个批发市场我知道，白天人来人往、熙熙攘攘的，晚上却门可罗雀。除了晚上七八点钟会有清洁车来这里把垃圾清运走之外，几乎过了下午五点，这个区域就鲜有人迹了。当然，那些无家可归的流浪汉不在此列。 我沿路看了看那些门店，想象着夜幕降临之后，这些紧闭的店门口的棚子下面，确实是挡风遮雨的好地方。 黄支队长一见我们下车，就匆匆走到我身边，拉住我的手问：“师弟，据说，这又是一起跨市的系列杀人案？” 我无奈地点了点头。我知道那一年，黄支队长被“云泰案”折腾了大半年，没睡过一个踏实觉，接着“云泰案”又引出了“六三专案”，让其内疚不已。现在他一听说可能是系列大案，不禁杯弓蛇影了。 “之前的那起是龙番市的那起，对吗？”黄支队长急切地问。 我点点头，说：“师兄少安毋躁。第一起确实发生在省城，而且这案子能不能归为串并案，依据很容易辨认，这三个字就说明了一切。” 我用手机把墙上的字拍摄了下来，通过微信发送给吴老大。 “老大，帮忙看看这三个字和上次那个，能不能确定系一人所写？” “怎么？又发案了？” "Ok." "Hold on." 我转头和黄支队长说：“开始我也没有想到，这起案件会跨市，而且距离这么远。” “唉，你看龙番，去年刚发生了系列案，今年又来了一个。”黄支队长摇摇头，说，“我得让他们的胡科长去九华山烧烧香了。” “你们前年发生了一个系列案，今年也被龙番的这个给拖进去了，我看你也得烧烧香了吧？”大宝在一旁嬉笑着。 “请注意你的表情。”我环顾了四周围观的群众，对大宝正色道。 “尸体是被一个店主发现的。”黄支队长重新戴上手套，把我们引到一家店铺门口的大棚下面，说，“早晨六点，这家店的店主来开门，发现门口的棚子下面躺着一个人。今天天气不好，当时光线比较暗，因为经常有流浪汉在附近寄居，所以他也没在意，就绕过躺着的人去开门。但是总觉得有一股血腥味，凑近那人一看，周围全是血，就大喊了起来。” “然后周围的店主就全跑过来围观，把现场踩得一塌糊涂，是吧？”林涛皱着眉头看了看地面上凌乱的血足迹。 “是啊。”黄支队长说，“现场大量不同的血足迹，估计都是周围的人踩踏的，没什么价值了。唉，刑侦剧播了这么多，还是没有培养起市民们的现场保护意识。” 大棚下的墙角处，有一床铺开的棉被，显然是死者睡的。棉被上方的墙壁上，有几束喷溅状血迹，地面有一大摊血泊，那床棉被也已经被血泊浸湿了。 “尸体已经运走了。”黄支队长说，“我们看到墙上那'清道夫'三个字，就觉得这案子不同寻常，立即通报省厅了。这才知道，你们半个月前，刚出过一个现场，也是写了这三个字。更要命的是，你们还没把那起案子给破了。” “唉！”我叹了口气，说，“要是破了，就没这起了。那起案子，凶手动作简单，下手狠毒，一刀致命。因为戴了手套和鞋套，所以没有在现场留下任何痕迹物证。” “这一起案件，凶手也是戴了乳胶手套！”大宝蹲在“清道夫”三个血字下面叫道。 根据傻四被杀案，我们归纳出了乳胶手套蘸血在墙上写字的特点，所以大宝在细细观察后，断定这一起命案的凶手也是戴了乳胶手套。 “哦？怎么看出来是乳胶手套？”黄支队长也凑过来看。 大宝指着墙上的三个字，逐点给黄支队长讲解，黄支队长在一边频繁地点着头。 我摘下手套，掏出手机，见吴老大的微信已经发了过来。 “经比对，确定是一种书写习惯，应该是一人所写。” “能不能联合两案现场留下的字迹，找出凶手的特异性书写习惯？” 特异性书写习惯是一个人不同于其他人的书写习惯，有的是习惯性连笔，有的是习惯性倒笔画，有的是习惯性的错字。总之，只要能找出特异性书写习惯，就能通过笔迹来比对嫌疑人的笔迹，从而认定凶手。 “有一点儿感觉，但是不能确定。我再看看，你们回来详说。” 听吴老大的意思，笔迹鉴定上仿佛有了突破的可能。但是，这并不能让我们兴奋。因为笔迹鉴定虽然可以作为甄别犯罪嫌疑人的依据，但是却不能作为排查范围的依据。如果我们无法缩小侦查范围，全省七千万人口，如何去逐一比对笔迹？ 现场虽然血迹凌乱，但林涛并没有放弃对现场的勘查工作。他蹲在地上，仔细地观察着每一处的足迹，仿佛想找出那枚与众不同的足迹来。云泰市的女痕检员张嫣蹲在林涛旁边，按照林涛的指点对每一枚足迹拍照。很显然，这个小女孩有些心猿意马。可能是因为林涛的外表，也可能是因为我们身上还没有散去的尸臭吧。I thought so. 因为尸体已经运走，中心现场也经过了勘查，我一时不知道我在现场还应该干些什么。于是，就在大棚下东看看、西看看。 突然，我看见墙角中心现场棉被的一端，有一顶安全帽。我赶紧快步走了过去，拿起来翻来覆去地看。 黄支队长看我对这顶安全帽产生了兴趣，就走到我身边，介绍说：“死者是个流浪汉，五十岁，本地人，精神时好时坏，周围的人都喊他老李头。因为死者是秃顶，所以他生前被别人看到的时候，总是戴着这顶安全帽的。估计睡觉的时候就扔在一边了。这顶安全帽我们家痕检员张嫣已经看过了，帽顶有喷溅状血迹，说明凶手杀人的时候，帽子是放在尸体附近的。帽子上没有新鲜指纹，也没有其他有价值的痕迹物证。” “哦。”我点点头，一脸兴奋，说，“即便它对侦破本案没有什么意义，我也很开心哪。” “为什么？”陈诗羽一脸茫然。 “保密，哈哈。”我卖了个关子，说，“至少这个老李头没白死，死了，也算做了件好事。” “快看！”林涛突然叫了起来，把正蹲在他身边出神的张嫣吓了一跳。 我没理睬陈诗羽的疑问，跑到林涛旁边，问：“怎么了？” “狗日的凶手，也戴了鞋套！”林涛说。 林涛指着一个血迹的轮廓，可以看出这个轮廓已经发黑，显然比其他的血足迹要干得早，而这个轮廓中央没有任何花纹，这是现场勘查使用的鞋套留下来的痕迹。 “这……不会是我们勘查的时候留下来的吧？”张嫣说，“在命案现场，我们经常可以看到这样的痕迹啊，都是我们的痕检员和法医勘查现场的时候留下来的。” “不会。”林涛说，“这个痕迹的周围有很多血足迹，都是围观的人留下的。我们可以对比一下看，这个痕迹的颜色明显较周围血足迹的颜色深，是因为它干得早，说明它只可能是凶手留下的！” “你好厉害啊。”张嫣挑了挑眉毛，“这都能看出来。” “正常。”我淡淡地说，“这两起案件是一个人做的，吴老大已经确认了。既然是一个人做的，手段方法自然也是一样的，一样的乳胶手套、一样的鞋套、一样的字迹。” 黄支队长张了张嘴，没说话，我知道他心里一定是各种担忧。而大宝则不断地吸着鼻子，甚至拿起死者那血染的棉被放到鼻下闻了闻。 “没啥好看的了，去殡仪馆吧。”现场仍然没有发现有价值的线索，我垂头丧气地说，心里暗暗鼓劲，希望可以在尸体上发现一点儿什么。 尸表检验工作有条不紊地在进行着，黄支队长一脸担忧。 老李头确实是个秃顶，但是由于长期戴安全帽的缘故，顶部头皮的颜色很白，和长期暴露在烈日下的面部皮肤形成了鲜明的对比。尸体全身黝黑黝黑的，由于大量急性出血，造成尸斑浅淡，以至于在他黝黑的皮肤上完全看不到尸斑的存在。 尸体上身穿着一件破旧的衬衫，前袖卷起，胸前的纽扣全部敞开，露出稀疏的胸毛。下身穿着一条解放裤，裤脚还沾着些许泥巴。 “他平时就这么敞怀穿着衣服吗？”陈诗羽问。 黄支队长摇摇头，说：“这个调查中没有反馈，大家对他衣着情况的印象不是很深。毕竟他天天戴着个安全帽，跟刚从工地下来似的，人们的注意力都被吸引到安全帽上去了。” 尸体的前襟敞开，所以整个胸壁、腹壁皮肤都沾满了血迹，已经凝结成血痂。在对尸体进行整体照相的时候，我们粗略地看了看尸体表面的皮肤。 “不会吧！出这么多血，怎么会没有伤？”大宝叫道。 我们确实没有发现尸体表面有明显的外伤。 “别急。”我见照相完毕，找了块毛巾蘸湿，慢慢地清理尸体身上黏附的血痂。 随着血痂一点儿一点儿地被清理干净，尸体胸口的皮肤纹理逐渐清晰起来。可以看出，死者一般是不敞怀穿衣服的，因为他胸口的皮肤颜色和手臂的颜色同样也有天壤之别。 “难道他只有在睡觉的时候敞怀吗？”我低语道。 “哟，这里果真有一处创口。”大宝又叫了一声，“很小。” 果真，尸体的胸骨左侧第三、四肋间，有一处小小的刺切创。所谓的刺切创就是刺器刺入人体后，拔刀的时候有个切的动作。这样的创口难以准确地判断出凶器的刃宽。 这处创口很窄，而且即使有切的动作，也能看出凶器的刃宽很窄。 大家都在低头思考，我拿起手术刀麻利地切开了死者胸部的皮肤，分离开肌肉，切断肋软骨，然后把胸骨和切断的肋软骨取了下来，暴露出了黄色的心包、纵隔和黑黑的肺。 “他生前抽烟吗？”陈诗羽问。 黄支队长摇摇头。 我说：“抽不抽烟很难通过肺脏的颜色看出来，这方面，空气污染的程度比吸烟厉害多了。” 说话间，我们已经取出了尸体的心脏。左心室上有一个破裂的小口，心包对应位置因为刺切，破裂口比心脏上的大得多，所以血液可以直接从这么小的创口里喷溅出来，没有受到心包的阻隔。而滞留在心包里的血液，则造成了心包填塞。 “创口贯穿心室壁，贯穿室间隔，但是并没有贯穿整个心脏。”我说，“这把刀可不短啊。” “而且你看，”大宝翻过死者胸部的皮肤说，“从皮肤的创口看，凶器很薄，和上一起案件一样。” 傻四被杀案中，凶手是用切颈的方法来杀人的，和刺心有所不同，但是从两起案件中不同的损伤看，似乎可以指向同一种凶器。 “凶器不是很长，但是也可以刺到心脏了，至少有个七八厘米吧。”我说。 大宝说：“而且胸部皮肤创口复原后，可以看到创角有撕裂的征象。” 我微微一抖，赶紧用纱布擦干净创口周围，说：“确实，有撕裂。” “有撕裂怎么了？”林涛在一旁好奇地问。 黄支队长说：“如果是锐器创，至少有一个创角是锐利的，就是被切开的，而不是被撕开的。如果像这个创口，边缘整齐，创角又有撕裂征象，只能说明凶器的前面有刃，后面没刃。” 黄支队长的话音落定，我们不约而同地看向我手中的那把手术刀。 手术刀的前段是刀片，有刃，而后段是刀柄，无刃。手术刀很薄，但是很锋利。手术刀比一般小水果刀要长。手术刀的刃宽很窄。 一切征象，都指向凶手使用的凶器是手术刀！ “手术刀是工作的利器，却不是杀人的利器。”黄支队长说，“若不是凶手找的位置很准，不可能一击致命。” “但是，手术刀像是一种象征。”我幽幽地说。 “戴我们的乳胶手套、穿我们的勘查鞋套、用我们用的手术刀。”林涛说，“凶手是想告诉我们什么呢？” “还有'清道夫'那三个字。”大宝说。 大宝一语让我从沉思中惊醒，我说：“赶紧把这边的事情料理清楚，赶回去看看峰岭市的案子怎么样，我们要回去找吴老大谈谈笔迹的问题。” 专案会议室里，黄支队长首先宣读了一条省厅的命令，说是鉴于两起案件的作案手段、侵害对象等问题高度统一，所以决定并案侦查。专案组指挥长由省公安厅刑警总队总队长亲自担任，两地的支队长担任副指挥长，两地分别抽调若干警力专门进行该案的侦查。这起案件被命名为“清道夫专案”。 我语速飞快地分析道：“本案和龙番市的案件可以串并，凶手使用了乳胶手套、勘查鞋套作为掩护，用手术刀杀人。两个受害者身上都没有抵抗伤，是在没有防备的情况下遭毒手的。这说明凶手可以很轻易地让人失去警惕心，但是这种本事是靠欺骗，而不是药物或者暴力，因为两个死者都没有中毒，头部也没有遭受打击。还有个问题我没有想清楚，若想找到准确的位置，在那种黑灯瞎火的情况下，必须去摸，摸到三四肋骨间隙才可以下刀，所以如果被害人是在睡梦中遇害，这一点就没法解释。尤其是，老李头的衣服是敞开的，有可能是凶手为了方便下刀才把他的衣服解开的，如果受害人当时很清醒，为什么会一点儿提防都没有呢？” “戴手套、鞋套，被害人还会没有提防？”黄支队长问。 我说：“究竟是用了什么办法，我们也不得而知，只能猜测，在当时的光线条件下，被害人看不清楚。凶手挑衅警方的目的很明显，可能是在炫耀，也可能是变态。但是之所以用有象征意义的手术刀作为凶器，说明凶手很有可能是医生或是公安人员。” “结合起来就是法医了吧。”陈诗羽说。 我没接话茬儿：“介于两起案件分别在两地，下一步要排查这几天云泰市的住宿记录，看有没有医生或公安人员。” “这工作量可就大了。”黄支队长说，“这几天的住宿记录怕是得有几万条，如果逐一把身份信息输入户籍系统再查职业，更是没边没际了。而且现在的户籍信息里也未必有准确的职业信息。” “死马当活马医吧。”我叹了口气，“凶手没有给我们留下任何可以突破的线索，受害人又是毫不相干的流浪汉，一般不会有什么矛盾纠纷，更不是为了劫财。所以，我也不知道下一步该从何查起。” “我插一句，”大宝慢慢地说，“刚才你说医生，最好改成医护人员。因为，我觉得凶手可能是个女性。” “女性？”我有点儿诧异，“下刀狠、准，而且力度可不小。刚才尸检的时候，我分离了创口周围肋骨的肋间肌和骨膜，可以看到三肋上有手术刀柄的压痕，这说明凶手的力度很大，不然很难形成。” “可是，我在现场闻见了一股香水味。”大宝说。 “香水味？你们闻见了吗？”我转头问张嫣等几个最先到达现场的勘查员。 Everyone shook their heads. 我指了指张嫣和陈诗羽说：“会不会是她们身上的？” 两名女警异口同声：“我们不用香水的好吧？” 我笑了笑，说：“这个问题不影响案件的下一步侦查。下一步除了排查周围监控、继续寻找可疑人员之外，再努力去找一找在云泰市开房住宿的人员。我知道这就像是大海捞针，但是我们在什么抓手都没有的情况下，再大的海，也得捞一捞。” 回峰岭市的车上，窗外夜幕降临，我们四人都昏昏欲睡。 突然，陈诗羽仿佛在梦中惊醒一样，捅了捅我，说：“对了，你今天不是对那个安全帽什么的超感兴趣吗？怎么刚才在专案组，压根儿就没提安全帽什么事儿啊？” 我说：“这安全帽跟'
