Chapter 2 Chapter 1 The Mistake of Mistakes
Master's finger landed on the back of the corpse.His fingers slid along the spine of the corpse, from the back of the head to the sacrum (the sacrum is located on the back wall of the pelvis), and the water stains on the back of the corpse slid away from his fingertips, as if a watershed had been opened. clear and distinct.
"Why don't you open the back?" As the fingers slid, the master's brows gradually knit into a ball.
As the deputy chief in charge of criminal technology, my master, Chen Yiran, is the most easy-going among the bosses of the Public Security Bureau.In his forties, one of his biggest hobbies is to tell us bad jokes. The boys in the team like to mingle with him.Now his expression doesn't look like he's joking at all, and my heart beat silently.
"Here, ahem." Gui Bin, the Chief Prosecutor of Shipei County Public Security Bureau, cleared his throat, ready to take over the conversation.
"I didn't ask you." The master abruptly blocked Gui's words, "I'm asking Qin Ming, why didn't you open the back?"
Under the watchful eyes of everyone, my face flushed instantly, I opened my mouth, but couldn't say a word.
The master slid his finger along the spine of the corpse again, pressed hard on several places, and said, "I think you may have made a mistake that you shouldn't have made."
Hearing that the master's tone was softening, Dabao, a brother of the same school, quickly rescued me: "Because this time we are in the initial survey site and the time is relatively tight, so we performed the dissection according to the general operation method, and did not dissect the back. "
I nodded vigorously from the side.
Generally speaking, forensic doctors conduct a "three-chamber" examination on the corpse, that is, dissect the cranial cavity, chest cavity, and abdominal cavity. Only in special cases will the back of the corpse be opened to dissect the back and spinal cord cavity.
"If you don't dissect, you have to press and check, right?" Master said bluntly, "I think as long as you check carefully, you will decide to open the back for inspection." The place.
"Well... this... mainly..." Dabao always stammered when he was nervous.
I stretched out my hand and pressed the place Master pointed at, but I didn't feel anything unusual.
Master saw my confusion, shook his head, and said, "Learn more and practice more, you still have limited experience. Open it."
In order to make up for the mistake, I quickly picked up the scalpel and cut along the trace where Master's finger slid. The knife peeled off the skin, revealing the yellow-white subcutaneous tissue and red muscle.Because of the tension, the edge of the knife looked crooked.
Standing on both sides of the corpse, Dabao and I separated the skin on the back of the corpse, and the whole muscle of the back was immediately visible.The color of the muscles was normal, and no obvious bleeding or damage was found.
I stopped the knife in my hand, supported the edge of the dissecting table with both hands, and secretly rejoiced, Master seemed to have made a mistake in his judgment this time. The atmosphere was so tense just now, and I don’t know how he will justify himself later.
Master glanced at me and sneered: "Don't get too excited, keep going."
Master saw through my thoughts, and my face turned red and white. I quickly picked up the scalpel again, and hurriedly began to separate the back muscles of the corpse layer by layer.
"Ah!" Dabao's hand suddenly stopped moving.
I poked my head over, feeling a sudden chill in my heart.
morning a month ago.
"When are you going to marry Ling Dang?" Master called me to his office, but he was not in a hurry to get into the subject, and asked while twisting a cigarette.Ever since I brought my girlfriend, Ling Dang, to the provincial capital, the cheerful Ling Dang quickly became acquainted with these guys from the head team.
"Master has started to gossip too?" I stretched out on the sofa in Master's office, "I'm only twenty-eight, don't be in a hurry."
"Don't let me say that I am not big or small," said the master. "You are now the chief of the forensic department. The first thing you need to do is to improve your professional level and be able to convince the public. Your previous performance was good, but Be vigilant at all times, be careful not to capsize in the gutter.”
Having been a leader for so many years, it is of course common for Master to do political and ideological work for subordinates. I have long been used to going in one ear and out the other.
"When you get married, you will be on wedding leave, you will be closing the mountain for forestry, and you will have children." The master continued, "The time will be tight at that time. Take advantage of the good time now, you should go to the scene more often, don't just It’s the big case, and the small case is also going to be run.”
Hearing this, I was shocked in my heart, and then I came back to my senses.Although it is a peaceful era, there are many murder cases in various parts of the province. As long as there is a murder case, the local public security organ's forensic doctor will report the situation to the provincial department. Do you want to be home everywhere?When the bell runs away, who will I marry?Who do you spend your wedding vacation with?Who are you going to have a baby with?
"It's not like asking you to go to every case." Seeing my bewildered look, Master couldn't help being happy, "Choose some cases that may have difficulties, such as this case, I think it's good."
Master threw me a piece of paper, I picked it up and saw it was a fax and telegram from the public security organ:
"Are we going to go to this kind of case?"
"No matter how small the case is, it is a human life." Master said, "Go ahead and make it more detailed."
Li Dabao, who had just passed by the door of Master's office, walked back backwards, poked his head out from the door, and asked, "Well, Master, where are you going? Can I go too?"
"Have you finished filing all your papers?" I said.
Dabao looked helpless: "That's too complicated. I've been working on it for a week. I can't sit still. If I sit for a long time, I will get hemorrhoids. Let me run, run!"
"Dabao came to the provincial department for training, not to train how to file documents." The master was obviously speaking for Dabao, "You two go together, and let the trace inspection department send someone to go with you, let Lin Tao go. "
Forensic medicine and trace inspection are not separated, and the investigation of the murder scene mainly relies on these two majors.Lin Tao can be regarded as my old partner. We are not only in the same survey team, but also graduated from the same school and entered the provincial department at the same time. As long as the other party has no other emergencies, we always go out in pairs every time we go out to the survey site. , Dabao often laughs that we are a good pair of "friends", even the bell sometimes booed.With Lin Tao on a business trip with me, I seemed to be in a better mood; but it should be Dabao who was in a better mood. He was about to hum a song while preparing the investigation box.I picked up the file and knocked him on the head, and said: "Still laughing, still laughing, the archives department will come back to trouble me, and I will trouble you."
Dabao scratched his head, gesticulated with his scissors hands, and said with a smile, "I don't have hemorrhoids at the survey site, yeah!"
After an hour's drive, we arrived at Shipei County.When the car drove past the stone river, I couldn't help looking out the window silently.One year passed, and it was the season of rape blossoms blooming again, but the girl who used to wear a floral dress could no longer see this beauty (see the case of "Qingming Flower Festival" in the first part of the "Forensic Qin Ming" series).It was almost noon, and the car stopped in a small village on the northwest edge of the county seat. As far as the eye could see, two-story small buildings were lined up one after another. Cooking smoke rose between the small buildings, and the smell of food stimulated everyone present. sense of smell.
A cordon was drawn around the small building at the scene.This small building looks no different from other small buildings, surrounded by a circle of walls, enclosing an independent small yard.In a corner of the wall, several trace inspectors were squatting on the ground to observe something. I didn't step forward to interrupt, but went straight to the forensic doctor Gui of the Shipei County Public Security Bureau: "Hello, brother!"
Forensic doctor Gui was looking for something in the investigation box, and I was taken aback: "Chief Qin, when did you arrive? Very fast!"
I smiled and went straight to the point: "Who is the deceased?"
"The deceased was an ordinary villager named Sun Xianfa. His wife died and his son was working in other places. Now he lives alone. Last night he went to someone else's house to help with the funeral, and he didn't leave until ten o'clock in the evening. It was originally agreed to be at three thirty in the morning today. I went there again to help with the funeral, but the funeral home didn't wait for him until four o'clock. The two families were very close to each other, only a five-minute walk away. When the family came out to look for him, they found Sun Xianfa lying in the corner of the wall, He was still breathing but was unconscious."
"Why is the funeral in the early morning?" I interjected.
"Yes, the custom here is to send the deceased to the funeral parlor before dawn." Forensic doctor Gui said, "I didn't expect that Sun Xianfa, who was kind enough to help, would also encounter misfortune."
"Is there a rescue process?"
"Basically nothing." Gui Forensic Doctor said, "We didn't find out that the person was injured until four o'clock in the morning, and the reporter called for help everywhere, and it was almost five o'clock when several people hurriedly sent Mr. Sun to the hospital. According to the medical records of the hospital, when Sun Xianfa was sent, he was already insensitive to light reflection, and he lost breathing and heartbeat after about half an hour of rescue."
"Where is the injury?" I asked.
"Head." Gui Forensic Doctor said, "It is said that there is one on the occipital, and his pupils were not too big during the rescue. The body was taken directly from the health center to the funeral parlor. I am going to go there after watching the scene."
"Then do you have a clue about the case now?" I asked the question I was most concerned about.
Forensic doctor Gui glanced at the yard next door. There were several people coming and going from the neighbor's house, and they were preparing to set up a table for dinner in the yard.He lowered his voice and said to me: "It's not hard to find the motive. The deceased in the family where Sun Xianfa helped with the funeral had an affair with him before he was alive. This woman's emotional life is rather chaotic, and she has ambiguous affairs with many people. She After the traffic accident, maybe one of her lovers was provoked, so she threw the fire on Sun Xianfa."
"I heard that there was only one wound on the head of the deceased, but there are no large arteries on the human scalp, so it is difficult to form a splatter-like bloodstain shape," I began to use the forensic expertise to reason, "So, the bloodstain here It should be spattering of blood, that is to say, the murderer hit the head of the deceased with the murder weapon, the blood adhered to the murder weapon, and as the murder weapon swung, it was splashed at the base of the wall."
From the bloodstains, it seemed difficult to draw any conclusions. I turned my head and asked the investigator beside me: "The first person who found Sun Xianfa, did he say what position he was in at that time?"
The investigator walked to the pool of blood at the base of the wall and made a gesture: "At that time, Sun Xianfa was lying on his back with his head facing the wall and his feet facing the gate of the yard."
supine?I didn't think too much, and went into the room with Lin Tao to continue observing.
The room was tidy and tidy. Before Mr. Sun happened, he might have been a very diligent man.The furniture and sundries in the main room were neatly arranged, and in the middle of the square table was a bunch of keys and two packs of unopened cigarettes.Next to him was his bedroom, and the quilt was neatly stacked on the head of the bed.
"It seems that there is no sign of disturbance at the scene, and it can be ruled out that the murder was caused by money. I guess, nine out of ten it was really a murder of love." I saw Lin Tao go up to the second floor, and turned to Dabao who was beside him.
"Well, the key is on the table. It seems that the deceased has already entered the house." Dabao muttered, "These two packs of cigarettes should be cigarettes from the funeral home, right?"
"It's strange that the deceased has entered the house, but has not gone to bed." Dabao and I walked into the bathroom and touched a few towels hanging on the wall. "The towels are all dry and there is no sign of washing. You Do you think the deceased was killed when he just entered the house and then went out, or when he was about to go out in the early morning?"
Dabao shook his head blankly.
I smiled and said, "Stupid. The deceased was found lying on the ground at four o'clock in the morning. If he was killed when he went out in the early morning, according to the previously agreed funeral time, he should have left the door around 3:30 in the morning." , Can such a big pool of blood be formed outside the house in half an hour?"
Dabao suddenly realized: "That's right! After all, no major arteries were injured. It should take at least several hours for a contusion on the head to form such a large pool of blood."
"Combined with the situation at the scene, the quilt is folded and the key is in the main room." I said that the deceased should have just entered the house, then went out again, and was attacked by someone on the back of the head after going out.But there is a problem. If the deceased wants to go out, he should go in the direction of the gate of the yard, but he walks in the opposite direction to the base of the wall. "How old is Sun Xianfa?" I asked.
"Forty-five." Gui Forensic Doctor paused, and continued, "His underground lover is only in his twenties."
"Hey, tender grass is so delicious." As I said, I put on my field investigation suit and walked towards the corner where the trace inspectors gathered.
"There are too few traces and physical evidence at the scene," Lin Tao said to me while squatting there, probing back and forth with an electrostatic adsorption instrument, "We haven't found any valuable clues yet."
The most conspicuous thing on the ground is a pool of blood, and there is a pool of vomit next to it.
"The vomit at this location should be the vomiting caused by the increased intracranial pressure after the deceased's head was injured. Combined with the shape of the pool of blood, it can be determined that this is the first scene where the deceased fell to the ground. In other words, the deceased was in the It was attacked here." While analyzing, I searched for traces along the base of the wall.
The wall surface of this wall was not painted, and the exposed red bricks were dark in color, so it was indeed difficult to find any traces of physical evidence.I took out the magnifying glass from the survey box and moved it up inch by inch along the wall. In the deep red, several strange spots suddenly came into view.I quickly extracted some suspicious spots and dropped a few drops of benzidine reagent, and the filter paper was quickly dyed emerald blue.
"It seems that these few drops are indeed bloodstains," I said, "judging from the shape of the bloodstains, it should be sprayed or splashed."
Lin Tao measured it with a steel tape, and was a little puzzled: "These few drops of blood spatter are only 20 centimeters from the ground, which is too low. Could it be that the deceased was lying on the ground and was beaten by others?"
why?What is he doing at the base of the wall?
"Well, also, he didn't bring a key when he went out, so he probably didn't close the door," Dabao said, "but the informant insisted that when he arrived, the door of the house was locked. He closed the door?"
"Let's go to the bottom of the wall and have a look." As I said, I picked up the inspection box, walked out of the small building, and walked into the yard.
The yard was not small. Five meters away from the wall, there was a hut built by the deceased himself with bricks. In the hut, there were brooms, dustpans and other cleaning tools.Dabao and I looked at each other and smiled. It turned out that this industrious little old man came to get tools for cleaning.
"The murderer should be lurking at the door of the house. He saw Sun Xianfa walk out of the house and moved his hand when he walked near the base of the wall." Dabao pushed his glasses on the bridge of his nose and said, "As for why the murderer closed the door for him, only the murderer understood."
I stood in the yard and looked up at the second floor of the small building.There is a row of aluminum alloy sliding windows on the second floor, and the window near the courtyard wall is open. Lin Tao is inspecting it attentively along the window frame.I winked at Dabao and said with a smile, "Lin Tao is really handsome, no wonder so many girls are chasing him."
"What's the use of chasing more people?" Dabao said, "Is he still single? How can you be happy?"
Far away on the second floor, Lin Tao also heard Dabao's voice. He looked down at me and greeted me, "Winter Gua, you see, the deceased really didn't have any sense of defense. This window is open. If anyone wants to break into the house, As long as you climb up the fence, you can reach the ledge of the open window with your hands, and then you can climb the window and enter the house."
"Your sister," I scolded, "what winter melon? Why do you call me a nickname in public?"
Dabao was laughing from the side, I patted his head and said: "What are you laughing at, I guess, if the deceased hadn't thrown himself into the trap and came out of the house, the murderer really might not have used this method." Entering the room."
"There are no suspicious traces on the second floor." Lin Tao said to us in the yard downstairs through the window, "It seems that there is no physical evidence at this scene, so I count on your autopsy work."
After lunch, Dabao and I rushed to the forensic autopsy room of the funeral home in Shipei County. The small dim room was the same as a year ago, unchanged.Forensic doctor Gui was already waiting for us at the funeral home, and with him was Guan Qijin, head of forensic medicine at the Shidan Public Security Bureau.Although the forensic doctor is in his fifties, he can be regarded as our senior. This time he will do the record work.
We first checked Sun Xianfa's torso and limbs systematically, but found no damage.
"Not to mention, the maintenance is really good," Gui Forensic Doctor said, "The body is white and clean."
"It can be seen that he is still a very diligent person. He lives in the house by himself and cleans it so clean." I said.
"Well, maybe his 'tender grass' cleaned it for him." Dabao picked up the scalpel and said while shaving the dead man's hair.
After Sun Xianfa's hair was completely shaved, the wound on the occipital region could be clearly seen.
"The two corners of the wound are blunt, and the edge of the wound is split along the texture of the skin, which can be seen inside the wound."
I picked up the hemostat, and while exploring the wound, I introduced the inspection situation, so that the forensic doctor at the side could record, "Bone fragments can be touched at the bottom of the wound, and it can be confirmed that it is a comminuted skull fracture."
I wiped the area around the wound carefully with alcohol and said, "This is a typical contusion wound caused by a blunt instrument hitting the head and tearing the scalp. You see, the skin around the wound is scratched. What does this mean?" "
"The surface of the wounding tool is rough, and the contact surface is larger than the wound." Dabao's theoretical knowledge is very solid.
"What kind of tool could that be?" I propped my hands on the edge of the dissecting table and moved my cervical spine, which had begun to stiffen. "Could it be a thick wooden stick?"
Seeing that we did not move the knife to dissect the head of the deceased, the forensic doctor who had been recording by the side was a little anxious: "It's not important, we just need to know the general type of the injury tool, hurry up, I'm not like you young people , My old lumbar spine can't hold it up."
The three of us have already been on the dissection table, and no one has recorded it except for the forensic doctor, so I can't say much, I lowered my head and began to cut the dead man's scalp.
The lower part of the contusion wound really corresponded to a comminuted fracture of the skull. After opening the calvaria, it was found that the fracture line of this comminuted fracture extended from the occipital along the base of the skull to the forehead.
"Hey, the force is really strong, the skull is broken like this." Forensic doctor Gui said.
I frowned and said, "Wooden tools can't form such a serious fracture. It seems that it should be a metal tool, and the surface of this tool is still rough. What could it be?"
Seeing that I was starting to struggle with the specific type of the wounded object, the forensic doctor pouted impatiently beside me.Although the forensic doctor has worked in the forensic system for most of his life, he has not made any major mistakes, and has not made any achievements. As long as he lives in peace and stability for another two years, he can retire with honor.It can be seen that he didn't take our speculations seriously at all. Although I was disgusted with this attitude of fooling around with work, I was too embarrassed to refute his face in public, so I had to continue to carefully remove the brain tissue of the deceased.
"Huh? Well, why is there cerebral hemorrhage on the forehead? The forehead scalp is not damaged." Dabao raised his elbow and pushed his glasses, then turned over the deceased's forehead scalp to confirm, "?"
"No," I said, "concussions only form when you fall."
I peeled off the dura mater at the base of the skull with hemostatic forceps, exposing the fracture line, and said: "Look, the fracture line extends from the occiput to the forehead, and because of the fracture, a hematoma forms on the forehead, which is consistent with the principle of concussion injury." It’s different. I think it’s more likely that the fracture will cause bleeding, and it shouldn’t be a concussion injury.”
"That's right." Forensic doctor Gui said, holding a study of the deceased's skull, "Look at the fracture line on the occipital bone that has been cut off."
We all know that only when there are multiple stresses and multiple fractures, the fracture lines will cross each other and be cut off.
"So, the deceased was hit on the head more than twice, but only one wound was formed." I said.
After the stitching was finished, I said, "Do you want to take a look at the back?"
Before the words fell, Guan forensic doctor protested: "I don't think so? It's getting dark, and the light here is not good. The key is that our forensic doctor can't play a big role in this case. The cause of death is very simple. You don't need to infer the time of death, and you have figured out the cause of the injury. The contradictions in the case are so obvious, are you afraid that you won't be able to solve the case? Besides, there is no way in this case that criminals ride on the dead. Look at the back what sense?"
I nodded. It seemed that the cervical spondylosis had occurred again, and I felt dizzy for a while, so I said: "What Mr. Guan said is true, the task is basically completed, let's call it a day."
Back at the hotel, we summarized the results of the day's on-site investigation and autopsy, and arrived at the task force's office before the special case meeting at 9:00 p.m.
"The deceased, Sun Xianfa, was violently attacked by a blunt tool on the head, resulting in severe brain injury and died." Although I am not experienced in many battles, I, who is standing here, have come all the way, and there is already a hint in my tone. As confident as Master, "During the on-site investigation, it was found that the deceased's house showed no signs of being turned over. We should rule out the murder of property. According to our analysis, the possibility of murder due to hatred is very high. The deceased was not in a state of falling asleep. It should be He just got home and was attacked after going out. The tool used by the murderer should be a blunt tool with metal texture and rough surface. Our technology can only provide so much support at present. The cause and effect relationship in this case is obvious, and it should not be difficult to investigate the clues. "
The task force leader nodded and gave the lead investigator a wink, motioning him to introduce the investigation.
"Sun Xianfa attended the funeral of his lover Liu Juye, and had a quarrel with villager Chen Changlin at the funeral. This is the most prominent point of conflict found so far." The investigator said, "Liu Juye is 24 years old this year. She was hit and killed by a vehicle while crossing the road at night. Her private life was chaotic. According to investigations, there were at least 17 people who had adulterous relationships with her, ranging from eighteen-year-old boys to sixty-year-old men. "
The entire task force shook their heads.
The investigator went on to say: "Currently we are sorting out Liu Guye's related people one by one for further investigation. On the other hand, we have also sent a working group to investigate Sun Xianfa's other contradictory causal relationships."
"That's fine." The task force leader said, "Except for those who have tasks at night, everyone else should rest. I believe this case will not be difficult to solve."
"Wait." I interrupted, "According to my analysis, the murderer should have followed the victim home, and the victim did not return home too late. Therefore, I think we should send more people to visit the nearby villagers and ask if there is anyone I saw the victim being followed that night. If we know the physical characteristics of the murderer, we can narrow the scope of investigation and make it easier to investigate."
"Qin Fayi's words are reasonable." The team leader said, "The people in the police station in the jurisdiction don't rest tonight, go to the place where the incident happened, and see who passed by the scene at night. Did you pass by here, did you see the victim and the person who followed him?"
After the project meeting ended, I returned to the hotel triumphantly, and said to Dabao who was lying on the bed next to me, "It seems that forensic medicine will not play a big role in this case. I guess it is very likely that the case will be solved through road visits. Do you believe me?" Do not believe?"
Dabao nodded, and said, "Your analysis is very reasonable. You follow and follow and wait for opportunities to kill people. I hope you can solve the case sooner."
The next morning, we returned to the provincial capital.
"How is it? Are you sure about this case?" Master asked after seeing that I had returned from a business trip for a day.
"No problem. There are obvious contradictions in this case. It is estimated that the case will be solved soon." I said, patting my chest.
Master nodded, without further questioning, and said: "Last year, the new forensic doctors recruited from all over the province have completed the training of new police officers, but most of the forensic doctors recruited in this batch are not graduates of forensic medicine majors, but clinical medicine graduates. , it is necessary to undergo professional training in forensic medicine. Given the large number of people, there are forty or fifty people, it is too difficult to train separately, and our province has an old-fashioned forensic professional college like Wannan Medical College. Resources cannot be wasted, so the provincial department decided to unify Organize the training. You graduated there, so you will handle the specific matters, complete the preparation work within half a month, give the trainees half a month to hand over the work, and start implementing the training work in early June."
The work of the provincial department is like this. In addition to the daily appraisal, prosecution and investigation site, it also includes heavy administrative work.Although the administrative work seems boring, but thinking that these tasks can effectively improve the overall case-handling level of the province's forensic doctors, I feel at ease and motivated to work.
Half a month is not long, and it is not short, but this busy time feels like time flies.In the past half a month, I have been very busy making reports, issuing notices, checking lists, contacting schools, making budgets, designing courses, and making appointments for professors. I have already forgotten the case of Sun Xianfa in Shipei County.
The preparations for the training were overtime, and it took me 21 days to get everything ready.
After clicking the "Release" button of the official notification, I leaned heavily on the back of the chair, looked up to the sky and let out a long sigh of relief: "It's finally done."
"Winter Gua, you see that you are so busy that you are pale every day, and you are not afraid that the bell will abandon you?" Lin Tao happened to pass by the door of my office and taunted.
"No." I said, "Who is like you, who has been abandoned countless times."
"How is it possible?" Lin Tao said with his neck tilted, "I abandoned others countless times, okay?"
I rubbed my face with my hands and said: "Okay, okay, you are handsome, you are popular, and you have countless ladies, okay? I have to rest for a while, I am too tired." After finishing speaking, I took out my cigarette and threw it away. Give Lin Tao one.
"What are you resting for?" Lin Tao said, "Shi Pei's case has come to an impasse."
I sat up straight and said, "Impasse? Why? Isn't the relationship between contradictions very clear?"
"The contradictory relationship is clear." Lin Tao said, "but all the more than a dozen related parties have been excluded, and there is no time to commit the crime. Other related points have not been touched, so now the special case team is at a loss, and the polygraph is used. , still to no avail."
"Is it incompetent?" I said, "Is it complicated for a simple case?"
"I don't know. Mr. Chen said that when he has some free time, he will take us down for a review. I won't chat with you anymore. I have a lot of things to do, so I'm busy first." Lin Tao turned and walked out of the office.
"It seems that Master is not worried about us." I said to Dabao who was in a daze at the side, "But this is a good thing. If the case is not solved, it will always be shameless. I believe Master can find more clues and evidence."
"Why have you been listless these two days?" Bell held the bowl and interrupted my contemplation.
Maybe it was stimulated by Sun Xianfa's case, or I was worried that I had missed something in the survey work. After a few days after I learned that the case had not been solved, I was really depressed and couldn't cheer up.
"Oh, it's okay." I tried my best to hide my emotions and changed the topic, "Can I eat at home, come to this chicken shop every day to drink chicken soup and eat chicken, is it uncomfortable?"
"What's a chicken shop?" Ling Dang covered her mouth and smiled, "It's really ugly. You drink chicken soup to nourish your brain, and don't you yell every day that you have a bad memory now? Look, this is chicken offal, and there are chicken hearts in it, chicken hearts and chicken hearts, Eat to remember."
"It's a shame that you still study medicine." I shook my head, continued to eat food in my mouth, and muttered, "Being a doctor, but still practicing feudal superstition, is there any scientific reason for that?"
Ling Dang put away her smile and said, "You must have something on your mind. You won't be happy to make you happy. Say, are you having an affair with someone? Did you do something that I'm sorry for?"
"Oh, auntie." I became impatient, "Who has nothing to do to engage in adultery? It's about work, about work."
"Tell me about work, too. Is it fun to be bored?"
Seeing that Ling Dang was a little upset, I said, "It's okay, it's just that the case I went to Shi Pei last time has not been solved yet. Master is going to review it tomorrow. I'm a little worried, afraid that I might be negligent."
Instead of being as relieved as imagined, Ling Dang's eyes became blurred instead.After being silent for a while, she raised her head and looked at me, her big eyes twinkling, and said, "Shall I tell you a secret?"
Bell always tells me "secrets", but I am not interested in her secrets at all.I gave a perfunctory "Oh" and continued to dig into my mouth, thinking, it should be that so-and-so who had an affair with so-and-so, and that so-and-so who bought an LV without telling my husband.
"Actually, I used to have a cousin. If she was still alive, she would be twenty-five years old." Bell put down the bowl and chopsticks, and said slowly.
I also stopped gobbling it up, the revelation was a bit of a gimmick.
"It's my uncle's eldest daughter, named Lin Xiaoxiao." Ling Dang continued, "Unfortunately, she was killed seven years ago."
"Seven years ago?" I said, "We didn't know each other then, did we? But why have you never heard of it?"
"The family has always been very taboo about this matter." Ling Dang showed embarrassment, "Uncle was greatly stimulated, and no one dared to bring up this case in front of him."
"Did your uncle's enemy do it?" When I heard the case, my nerves would become sensitive unconsciously, "Otherwise, who would attack an eighteen-year-old girl?"
Ling Dang shook his head slowly, with a trace of sadness on his brows: "The case has not been solved until now."
"Not broken?" I almost jumped up.Even seven years ago, the public security organs in various places attached great importance to the detection of homicide cases, and almost all the police were mobilized in the case of a homicide case.At that time, the prefectures and cities with a homicide detection rate of 90% accounted for most of the province.I have always believed that murder cases must be solved, but I never thought that there would be such an unsolved case around me, and the victim was Ling Dang's relatives.
"That happened in your hometown Yuntai?"
Ling Dang nodded and said, "Yes, it happened at Yuntai No. 12 Middle School. You were still in college at that time, so you must not have known about this backlog of murder cases."
Ling Dang has been with me for a long time, and I know a lot about the common sayings of the police.Homicide backlog refers to unsolved homicide cases, which refers to the debt owed by the police to the people.If the murder case is not solved, it is bound to leave a knot in the hearts of the criminal police.
"So... have you guessed who did it?" I asked.
"Oh, that's why the family doesn't want to mention this matter again." Ling Dang paused, sighed, and said sadly, "Laugh at her, she was raped."
I gritted my teeth secretly.
"Xiaoxiao's body was found in the school's public toilet." Ling Dang continued to recall, "There were a lot of onlookers at that time, and Xiaoxiao was just like that... Well, she has always been a very obedient and cheerful little girl. I went to play at my uncle’s house, and I saw smiling awards all over the wall, really, even the kindergarten ones. My uncle is the most proud of this daughter. Seeing that scene with his own eyes, his whole body collapsed. I don’t think so. I know how he survived in the end, but since then, no one of us dared to mention Xiaoxiao’s name. Let the past pass.”
I lowered my head, picked up the bowl and chopsticks again, and slowly swallowed the rice.
"At that time, there were no clues in the case. The police investigated for more than a year and questioned many people. We all saw it. But the murderer couldn't be found, no matter what. After the initial pain and anger passed, we I also began to slowly accept this reality. Maybe not everything can be achieved as long as you work hard. If things don’t end up as you think, then you have to learn to let go and move on.” Ling Ding said Here, he gently poked me with his chopsticks, "Hey, I've said so much, do you understand what I mean?"
I put down my chopsticks, squeezed her slender fingers, and smiled.I understood Ling Dang's kindness, but the flash of tears in her eyes also made my heart sink slightly.Can everything really pass?Whether it's Xiaoxiao or Sun Xianfa, what they need may be the truth.
Early the next morning, Master took me, Dabao and Lin Tao to Shipei County.When we came to the small building where Sun Xianfa lived, the master got out of the car first, and after a brief exchange of greetings with the director of the Shipei County Public Security Bureau, he picked up the on-site investigation box and walked into the scene. I gave Dabao a wink, and Dabao hurried up Before grabbing the heavy box from Master.
Dabao and I watched Master come in and out to observe the scene in the yard, while the investigators introduced the situation at the scene and the location of the corpse.Master suddenly beckoned to us, and Dabao and I hurried over.
"Didn't you find any contradictions at the scene?" Master asked, "Can the position of the corpse and the shape of the blood be explained?"
I thought about it, then nodded silently.
"You said that the deceased fell to the ground near the base of the wall by the murderer hitting the occiput from behind." Master stood at the position we imagined, and reconstructed the process, "Then, the deceased fell to the ground, either with his head facing the courtyard door and on his back. , or fall prone on the ground with the head against the base of the wall."
I pondered for a moment, and it sure sounded like it should be.
"But the dead man was facing the wall with his head on his back." Master said, "How do you explain it?"
I faltered and hesitated for a moment.
“行了，现场就这样。”师父并没有对这个矛盾点进行解释，指着现场堂屋桌子上的两包烟，对身边的侦查员说，“去查一查，办丧事的那家发的是什么烟。”
“尸体昨天早上就拖出来解冻了。”桂法医说，“现在可以进行检验了。”
“那我们现在出发吧。”师父脱下手套，说。
没有按照常规的解剖术式，师父选择先检验孙先发的后背。在我和大宝手忙脚乱地把尸体的后背肌肉逐层分离开以后，居然发现尸体的后背真的有损伤。
“师父真神！”大宝惊讶地叹道，“那个，您怎么摁了两下就知道有损伤？”
师父显然还在因为我们第一次工作的疏忽而生气，没有回答大宝的问题，说：“七根椎体棘突骨折，深层肌肉大片状出血。我现在想问，这样的损伤通常在什么情况下形成？”
此时的我大脑一片空白，我隐约意识到自己犯了大错。
“作用力巨大，作用面积大。”桂法医替我们回答道，“通常在高坠伤中比较多见。”
师父瞪着我，一动不动，就这样足足瞪了两分钟，才厉声说道：“打开颅腔。”
我颤抖着手，沿着原切口，剪开了缝合头皮的缝线。拿开颅盖骨，死者的脑组织咕噜一下从颅腔里翻滚了出来。
师父用脏器刀一层层切开脑组织，说：“说后背没打开，是工作疏忽，但是这个头颅损伤，你们看不出来是怎么回事？”
“您是说对冲伤？”我辩解道，“我觉得这个损伤不是对冲伤。虽然他是枕部着力，却在额部形成血肿，我觉得额部的血肿是横跨颅底的骨折形成的。”
“你有依据吗？”师父皱起了眉头，“我猜，你的潜意识里认定了这是一起凶杀案件，所以用猜测的态度排除了它是对冲伤的可能。”
“不，我们发现死者的头部有骨折截断现象，应该不止一次打击，高坠怎么会有多次受力？”我极力辩护着。
“你说的是这处？”师父指着颅骨上的骨折线说，“凹陷性骨折，会在颅骨受力中心点周围形成同心圆似的骨折线，同时也会以此为中心点，形成放射状的骨折线，放射状的骨折线遇见同心圆似的骨折线，自然会截断。所以，这不是截断现象，而是凹陷性骨折的典型现象。”
我盯着颅骨仔细地观察着，心里还有些不服气。
“别不服气。”师父说，“如果是骨折线形成的血肿，应该在整个脑底沿着骨折线的地方都有血。而死者枕部和额部的两处血肿彼此孤立，并无连接，这是对冲伤的典型特征。而且，骨折形成的血肿，血是黏附在脑组织外的，对冲伤形成的血肿是在脑组织内的。这是因为骨折形成血肿的原因是骨折断段刺伤脑组织，而对冲伤形成血肿的原因是脑组织撞击颅骨形成的内部脑组织挫裂。这个死者额部的血肿，用抹布是擦不掉的，所以血肿是在脑组织内部的，符合对冲伤形成的脑内血肿。”师父一边说一边用抹布擦拭他手里脑组织上的血块。
我像是泄了气的皮球，站在一旁发呆。
师父接着说：“另外，如果死者遭受多次打击，下意识的反应应该是用手护头，这样，他的手上就可能因为凶手的第二次打击而形成抵抗伤，或者手上沾有血迹。可是，死者的手上既没有伤，也没有血。”
这些论点都很有说服力，我暂时没了反驳的依据。
“不可能吧，”桂法医说，“您真的觉得他是从高处坠落摔死的？”
师父点了点头：“依据尸体上的损伤，我有充分的证据确认死者系从高处坠落，背部和枕部着地，导致死亡的。”
“我还有个疑问。”我仍在负隅顽抗，“现场死者躺着的位置，离地面二十厘米高的地方发现了死者的血迹，高坠怎么会有喷溅状血迹？”
师父想了想，突然眼睛一亮。他用止血钳指了指死者颅底的骨折线，说：“颅底骨折，颅内的脑脊液和血会通过颅底的骨折裂缝漏到口鼻腔内，由于死者的意识模糊，所以血液和脑脊液会被死者吸进气管，这样死者会呕吐、呛咳，血迹自然会被死者呛咳到墙壁上。”
我想起了现场血泊旁的呕吐物，看来师父分析得丝毫不差。
师父用刀划开死者的气管，说：“看，不出所料，他的气管里都是些血性泡沫。”
最后一个疑点都被师父解释合理了，我彻底放弃了抵抗，看来死者还真的是摔死的。
“可是，”我说，“半夜三更的，孙先发为什么会从高处摔下来呢？如果是高坠的话，他原始躺倒的位置正上方就应该是他坠落的起点。”
我说完，脱下手套，走到解剖室外的办公室里，打开了电脑里的图片：“那么，坠落的起点应该是靠近小楼外墙墙壁的围墙墙头上。他半夜三更爬自己家的墙头做什么？”
“那，那个……既然是摔死的……”大宝因为我们的失误而乱了分寸，“是不是赶紧要撤案啊？”
“别急，”师父说，“死亡方式是高坠，但不表示这一定是一起意外，下面我们就要搞清楚死者半夜高坠的原因。”
“死者从自己情妇的丧礼上喝完酒回家，把香烟和钥匙放在屋内，自己又走出屋外，锁了屋门，爬上墙头，然后跳下来摔死？”我一边回溯时间顺序一边说，“殉情，还是偷窥？”
看到我们都开始深入思考，师父的气才消了一些，他被我的这个假设逗乐了：“你还真有想象力，偷窥都能想得出来，他的邻居都是些老弱病残，有什么好窥的。”
师父的话音刚落，侦查员就走进了解剖室：“报告陈总，按照您的指示，我们去调查了刘家办丧事当天参加丧礼的部分人员。这些人都反映，刘家没有给每个人发香烟，饭桌上放着的香烟是玉溪。”
我一时丈二和尚摸不到头脑，这发什么香烟，和破案，不，现在应该说是对还原事件过程有什么用呢？
师父一边脱下解剖服，一边拿出一根烟，点上后，深深吸了一口。
我们都整齐地站在师父身边，等他开口指示下一步工作。
突然师父说：“应该是这么回事。”
我们都是一头雾水，我忍不住问：“应该是怎么回事？”
“你们之前说死者是进了屋以后，又出门爬墙头，是吗？”师父问。
“是啊，”我说，“他把香烟和钥匙都已经放在堂屋的桌子上了嘛。”
师父笑了笑，说：“桌子上的物品，有可能是死者回到家里放在桌子上的，也有可能是死者下午离开家去参加丧礼的时候，根本就忘记带在身上的。”
被师父一点，我恍然大悟：“哦，对，是啊！”
“是？那个，是什么？”大宝还没能反应过来。
我接着说：“如果是死者根本就忘记带钥匙和香烟出门，香烟不要紧，没钥匙，他晚上怎么进家门呢？”
“嗯，”桂法医抱着双手，慢慢地补充道，“所以陈总才会让侦查员去调查香烟的问题。目前看来，刘家给参加丧礼的人们提供的是玉溪，而死者家里放着的，是云烟。”
我补充道：“既然死者家里的烟不是下午丧礼上的烟，那么就不能根据香烟、钥匙在屋内而推断死者已经进了家门。这样看来，死者下午出门的时候，很有可能就是忘记带钥匙和香烟了，所以他晚上就进不了自己的家门。”
“进不了家门，”师父继续发问，“如果是你们，你们该怎么办？”
我重新坐在解剖室外的办公室里，在电脑上一张一张翻看着现场照片。
“知道了，”我眼前一亮，“你们看，死者坠落的地方上方是墙头，墙头旁边就是小楼的二楼窗户，别忘了我们第一次现场勘查的时候，二楼的窗户是开着的，当时林涛还说这样开着窗户很危险。”
“是了。”林涛一直在旁边听我们的分析，这时候也开了口，“死者应该是爬墙头想移到窗户旁边，翻窗入室，可是他喝了酒，手脚不稳，就从墙头上摔了下来。”
“现在我们该怎么办？”我摩拳擦掌，蠢蠢欲动，想赶紧弥补自己之前犯下的错误。
“不好办。”师父说，“现在的一切都只是推断，更糟糕的是，之前县局已经立案而且通知了死者家属。如果没有充分的事实依据支持，我们就这样去通知家属，那人家一定会说是你们公安破不了案就说死者是自己摔死的，要我，我也不信服。”
我低下了头，知道这是师父在变着法儿数落我。
“行了。”师父看见我自责的表情，又于心不忍，接着说，“现在我们去现场吧，希望能在现场找到有用的证据。”
“这事儿不能全怪冬瓜。”林涛也听出了师父责怪我的意思，上前帮我挡了一枪，“我们痕检也有责任。我觉得我们这次是可以找到线索的，因为第一次勘查，我们只勘查了坠落点地面和二楼的窗框，对于死者可能触碰到的墙头、二楼窗台我们并没有仔细看。”
“这不能怪你。”师父铁了心让我挑全责，“法医没有搞清楚致伤方式，错误重建现场，你们自然不可能在对的地方寻找痕迹，秦明这次难辞其咎。”
我又低下了头，这次的教训的确够深刻的了。
到了现场，林涛只身爬上了近两米高的墙头，用放大镜在墙头上寻找着痕迹，另几名痕迹检验员在二楼研究窗台。此时此刻，帮不上忙的我只能焦虑地在院子里打转，期待着他们的好消息。
师父的推断又一次接近了事实，很快，林涛和他的弟兄就在墙头和窗台找到了直接证据。
“墙面、墙头的痕迹已经可以证明一切了。”回去之后，经过比对，林涛高兴地向师父汇报道，“虽然过去一个月了，但是现场一直封存得很好，痕迹物证都没有遭到破坏。墙面有明显的蹬擦痕迹，是死者上墙的时候留下的，墙头也有几枚死者的完整足迹，其中一枚右足足迹有变形，有擦挫，应该是滑落的时候留下的。”
“窗台上也有死者左手的指纹和掌纹，从方向上来看，是从外到内的，也就是说死者的左手已经搭上了窗台，但是右手没有来得及搭上来。”另一位痕迹检验员说。
“我也有发现。”师父拎着死者的一双鞋子，说，“我仔细看了死者鞋子的边缘，右脚的鞋子边缘有和硬物摩擦形成的损伤。方向是从下到上，这个证据也可以印证死者的脚和墙头有摩擦滑落。”
“那么，现在看来，”大宝插话道，“死者应该是左手上了窗台，左脚和右手悬空，右脚突然滑了，导致他仰面下落着地。这样也就解释了死者为什么会是头朝墙根仰面着地的姿势。”
我在一旁默默无语，看着他们一点点重建出现场，还原出事实真相。
有了充分的现场证据，案件很快就撤销了。又睡了一晚上郁闷觉，我起了个大早，到师父办公室主动检讨。
师父的态度和我想象中大相径庭，他温和地问：“知道自己犯了什么错误吗？”
我点了点头，说：“知道，先入为主、工作不细致。”
“嗯，总结得很好。”师父说，“你刚去，所有人都说是命案，所以你也认为是命案，但是你忘记了一个法医最先应该搞清楚的，就是死者的死亡方式。因为先入为主的思想，所以你主观臆断地排除了一切意外事件的可能，最要命的是没有细致解剖，遗漏了背部损伤这么重要的一个线索。其实，你当时要是打开死者后背，你的判断一定会发生天翻地覆的变化。”
“其实，是老管一直在催我快点儿结束，所以我没打开后背。”来之前我已经想好了无论如何不辩解，结果这时候却又忍不住为自己辩解。
师父语重心长地说：“你是省厅法医，错和对都要你来承担责任，你不应该受到任何人的影响。幸好这个案子一直没有抓人，如果让别人蒙冤入狱，你的良心又如何得以安宁呢？”
师父说的在理，我默默地点头。
“法医不好干啊。”师父说，“好在你运气好，这次失误并没有造成什么严重的后果。错误判断一起案件，浪费大量警力不说，可能会让清白的人蒙冤，也可能会让犯罪分子逃脱法网，所以说法医的责任真的很大。你要想当好一个法医，就要时时刻刻都不忘记认真、细致。不要害怕失误，要有信心继续迎接挑战，因为我们有我们的武器，那就是法医科学。科学是可以战胜一切的。”
我深吸一口气，抬起头来：“相信我，师父，给我一次将功赎罪的机会。”
