Chapter 22 Case 20: The Ring at Midnight

"Is it 110?" A childish voice asked quietly. "Yes, how can I help you?" The voice of the 110 operator. "A masked gangster broke into our house, come and help." The immature voice was mixed with heavy panting. "What is your exact address?" "Extraordinary wedding photography main store." "Is it the extraordinary wedding photography at the east end of Binjiang Avenue on the outskirts of the city?" "Yes, come and help!" The childish voice suddenly raised its pitch. "Hello... hello... are you still listening? Do you know that person?" The voice of the 110 operator was urgent, but there was silence on the other end of the line.

"Who is calling for help?" Suddenly there was a rough voice, followed by fierce fighting and cries for help, and soon, the cries for help turned into moans of "Ouch, Ouch".After a moment of silence, there was the sound of "bang bang" kicking the door, followed by a scream from an immature voice, and then the phone turned into a busy tone. I silently took off the earplugs, turned off the computer, and took a deep breath.According to the requirements of the task force, all members of the task force must listen carefully to this alarm recording tonight, hoping to find a clue from the recording.

It was a dark and stormy night, and I listened to this recording a dozen times alone in my hotel room.After turning off the computer, I stretched out on the bed and turned off the lights.It was such a tiring day, I felt sore all over, as if I couldn't stand up again.As soon as the light was turned off, there was a voice lingering in my ears, sometimes it was the voice of a child, and the miserable cry for help lasted for a long time, and sometimes it turned into a helpless moan.I suddenly felt creepy, sat up on the bed again, and turned on the overhead light of the hotel. It's a sad day, and I can't help but feel dizzy when I see so many bodies lying horribly in the funeral home.The sympathy for the deceased and the hatred for the criminals kept surging in my chest. I didn't care about the fatigue of the journey. I re-examined the murder scene with Dabao, and then worked with the forensic doctor of the Leiying City Public Security Bureau to conduct an investigation on the 6 corpses. The system dissected and worked continuously for 15 hours.After the work was over, we ran to the roadside stall hungry for a bowl of beef noodles, and then returned to the hotel. According to the requirements of the task force, we silently listened to the creepy alarm recording.

I don't know if Dabao next door is asleep at this time, but I don't feel sleepy at all right now. The tragic scenes of the scene and the dead body are scrolling in my mind one after another, stimulating my most sensitive nerves.The special case team knew that the workload of criminal technology was very heavy, so they did not ask us to participate in the special case meeting in the evening, but asked us to participate in the special case meeting tomorrow night after careful work. The process of the case will start early this morning. At around 1:00 this morning, the 110 command center of the Leiying City Public Security Bureau suddenly received a call to the police, and the content of the call was this alarm recording.After receiving the alarm, the 110 operator immediately notified the nearest police station from the scene.The police drove to the scene like lightning. Because it was late at night, there were not many vehicles on the road. The police arrived at the crime scene on the edge of the Xincheng Development Zone 5 minutes later, and found that the shutters on the facades of the three rooms were locked. The light was on in the room.After the police shouted and got no response, they urgently used a crowbar to pry open the rolling gate and entered the scene.After inspecting the first floor and found it was empty, they went upstairs and found a man lying on the ground at the stairway, and the corridor on the second floor was covered with blood.While quickly dialing 120, the police inspected the two bedrooms with open doors on the second floor, and found that there was one person lying in each of the two bedrooms.Although the body temperature of the three people was still there, before 120 arrived, the police confirmed that the three people were all out of breath.

In view of the fighting sound in the alarm call before the deceased died, the task force believed that the criminals could not run away, so they immediately set up a net and organized more than a hundred policemen and armed police on duty to rush to the scene immediately, search the surrounding area, and set up checkpoints to monitor the passing vehicles. Check, hoping to find the suspect with a lot of blood on his body.Unfortunately, after a night of interrogation, no suspects were found. On the other hand, all members of the criminal technology department were mobilized to inspect the scene.Because the scene was full of blood and fighting traces, the site investigation was very difficult.However, when the on-site investigators pried open the other rooms on the second floor that were locked from the outside one by one, they found that there were actually three dead bodies in the easternmost room.

I got the order at 4 o'clock this morning.Master called and briefly introduced the case, emphasizing the seriousness and severity of the case, and asked me to gather in the hall immediately.So I called Dabao, and went to Leiying City with a provincial and departmental support team composed of more than 10 policemen from the Criminal Technology Division and Criminal Police Corps led by Director Liang. Leiying City is the farthest prefecture-level city from the provincial capital. The whole journey takes the expressway, even if it is speeding, it will take at least 4 hours.During these more than 4 hours, Dabao and I slept soundly in the car, accumulating energy for the next hard work. It was not until 9 o'clock in the morning that we were woken up by the driver and found that we had arrived at the scene of the crime. on site.

The crime scene was located in the very remote suburb of Leiying City, with not many residents and not many onlookers.The scene was cordoned off, and more than 30 police cars were parked around the cordon, and there were more than a hundred police officers in charge of peripheral surveillance and search.This is the first time I have encountered such a formation, and suddenly I started to feel drums in my heart, and I lost confidence in myself.I have just been working for 6 years, and I am assigned to preside over the forensic work of such a major case, which really makes me nervous.It was only later that I found out that it was actually Master who forced me to become a forensic medical technician who could be my own.

The special case team built a simple shed next to the scene to shield the project headquarters from the still hot sun in early autumn. After more than 10 of us arrived at the project headquarters, we immediately took our positions, and began to understand the case along with the contacts of the corresponding departments. Wang Haiyang, the head of forensic medicine in Leiying City, is my elder brother. He is a calm and steady 40-year-old man. He has worked hard for more than 10 years and cooperated closely with the criminal police department of Leiying City. 100% homicide detection rate. After a brief exchange of pleasantries, Forensic Doctor Wang and I began to introduce the situation at the scene.

"This is an old house, built many years ago." Forensic doctor Wang said, "The house is the ancestral home of the family of the deceased Zhang Niannian. Zhang Niannian led his family to do wedding photography business eight years ago. Professional wedding photography, but their low price still attracts the favor of many working-class and suburban farmers.” "This place is really out of the way." I interjected. "It looks remote, but it's not remote." Wang Forensic Doctor said, "This place is gradually being developed because of the integration of urban and rural areas. However, the surrounding buildings of this house are still under planning, and the nearest village to this house is actually 500 meters to the west. outside."

I followed Dr. Wang's fingers, and I did see smoke curling up from the kitchen about 1 mile away. "But this land is under development, so this lonely building has become a dangerous place. It's really dark here at night, and it's easy to be spotted by criminals." Forensic doctor Wang said, "Over the years, the Zhang family has They want to make it bigger, and opened two branches in the city. But this is still their main store, where they spend the most energy, and they will live here at night.” "There are many employees in this store?" I asked. "In addition to the hired photographers and technical staff," said Forensic Doctor Wang, "there are also many temporary workers who arrange and transport wedding dresses, photographic equipment and other items, which can be regarded as supporting a lot of people."

"Six dead?" I asked in surprise. "Well, six of them died." Forensic doctor Wang said, "After identification by relatives, the deceased were Zhang Niannian, his wife, their two children, and Zhang Niannian's parents." "What? A family? The Zhang family was exterminated?" I jumped up in shock. Forensic Wang nodded silently.My blood rushed to my heart, and I swore that I would find the murderer and shoot him. This bastard would not spare even a child. "Let's take a look at the entrance and exit of criminals first." Forensic doctor Wang saw my thoughts and pulled me back from my anger. "The house is located on the north side of the newly opened Binjiang Avenue. The facade on the first floor leads to the roadside." Wang Forensic Doctor said, "The house is a two-story structure. There are three large rolling gates on the south side of the first floor, and the studio and office on the inside. There are no doors on the side, only windows. Next to the office on the first floor, there is a staircase leading to the second floor, and there is an east-west corridor on the second floor, which connects the doors of the six rooms." While listening to Wang's introduction, I followed Wang to the back of the room.There are really only 6 windows on the back side of the house, all of which are equipped with anti-theft windows.It was obvious that two bars of a security window had been sawed off, the sliding window inside was also open, and the curtains were blown up by the wind. "Is this a fresh saw mark?" I pointed to the two sawn fences. Forensic doctor Wang nodded and said: "Now the trace inspection department has confirmed that the murderer came in and out from here, but there is no trace evidence that can identify the criminal. The murderer should wear gloves and came prepared." I followed Forensic Doctor Wang around the house twice, but found no new clues, so I said, "Why don't we hurry up and go into the center to have a look." Forensic doctor Wang and I put on our on-site investigation equipment and walked carefully into the central site.A rolling gate at the scene has been pried open by the police. We walked into the first floor of the scene through the lifted rolling gate, and found that the first floor of the scene is a hall, where various wedding dresses and various equipment for wedding photography are placed. with background.At the east end of the hall, a small room is separated by tempered glass, and a sign of "Finance Room" is hung on the glass door. I walked to the door of the financial room and pulled the glass door.The glass door was not locked, and I walked in with Forensic Doctor Wang. "Is there anything going on in the financial office?" I asked. "After investigation, the criminals did not enter the financial room." Forensic doctor Wang said. "There is no sign of this safe being intruded?" I noticed a safe in the corner of the financial room, so I pointed and said, "If it was robbery and murder, and the criminal entered from the first floor, then he should first enter the safe." Find your belongings in this unoccupied treasury office, right?" Forensic doctor Wang nodded and said: "Not only that, but after investigation on the second floor, it was found that there were a total of 70,000 yuan in cash in the cabinet of the master bedroom and the deceased's clothes, and they were all placed in places that were relatively easy to find. As long as the murderer simply rummaged through , it will be found.” "So, now it's considered vengeance, right?" I asked. "Yes." Wang forensic doctor said, "If it was a robbery, there is no need to kill so many people, even infants. Now all the forces of the task force are looking for the contradictory relationship of the deceased before his death." I nodded, took a brief look at the tidy financial room, clapped my hands, and said, "Come on, brother, go upstairs and have a look." In fact, walking in the corridor, I smelled a strong smell of blood.Turning a corner from the stairs and going up to the second floor, I found that the scene in front of me was horrible. At the end of the stairs, I saw the corpse of a man in his 30s lying on his side in the corridor wearing only briefs, with a pool of blood under his body.The male body was identified as that of Zhang Nian, the owner of the wedding photography shop.The door behind the corpse was wide open, and the bloodstains on the corridor were very messy, extending all the way into the house. "Look, the traces of fighting are very obvious." Forensic doctor Wang said, pointing to the messy mopping-type blood stains on the ground. I squatted down and briefly looked at the dead man's body.The skin of the corpse was basically stained with blood, and the deceased was completely a blood man, and it was not clear how many wounds there were on his body.However, the shape of the blood on the corpse caught my attention.On the outside of the deceased's thighs, there were more than a dozen bloodstains in the form of pours. The direction of the bloodstains flowed from the front side of the thighs to the back side. The bloodstains had dried up and formed blood scabs on the skin.Although there are other rubbing and contact-like bloodstains covering the dozen or so pouring bloodstains, the direction of the pouring bloodstains is still clearly visible.The skin on the back of the deceased's thigh and calf was completely covered in blood, and the faint blood covered most of the skin, presenting a light-blooded state. I always feel that such a bloodstain shape is a bit abnormal, but I can't figure it out.I didn't continue to think about it, and "jumped" into the master bedroom step by step on the blood-free ground.The master bedroom is very large, with wardrobe, big bed, coffee table, sofa, TV and combination cabinets, and it looks very spacious.The floor of the master bedroom also had a lot of messy bloodstains from the struggle, which were randomly smeared on the floor.Next to the bed in the master bedroom was the corpse of a young half-naked woman, who was confirmed to be Zheng Qian, the wife of the host, Zhang Nian.Zheng Qian also only wore a pair of briefs, holding a towel quilt tightly with her hands and covering her chest.The towel was completely soaked in blood, and it was also impossible to see where the wound was.Zheng Qian's head was on the bed, her mouth was slightly opened, and her round eyes were staring. "There will be no sexual assault, right?" I frowned. After working for so long, what I fear most is a rape case, and there will always be a wave of anger in my heart. "Probably not." Wang forensic doctor said, "A condom was found at the scene, and the deceased's clothes were neatly placed under the pillow. We analyzed that the young couple had just finished their married life, so they didn't wear tops. Condoms It has been tested for further confirmation." I looked around the master bedroom, and suddenly, a bloodstain caught my attention.It was a large dripping bloodstain, right beside Zheng Qian's death bed.The diameter of the dripping bloodstain is about 1 meter, and it is in the form of vertical dripping bloodstains. Each drop is very thick. I roughly counted it, and there are about 50 drops. "Brother, look at the blood, what's the situation?" I was full of doubts, so I couldn't help asking.I always feel that this kind of revenge scene is a bit strange, but I can't explain why, so I want to ask Wang Forensic Doctor if he feels the same. Forensic doctor Wang nodded and said, "I saw it at first, but I can't tell how so many dripping blood stains were formed. Let's talk about it after the DNA results come out." "Has all the blood at the scene been extracted?" "Yes, during the four or five hours you were on the road, we took more than 200 on-site blood samples. The provincial department coordinated and coordinated, and the DNA laboratories of the public security bureaus in several surrounding cities fully cooperated to help with the test. It is estimated that tomorrow morning All have results." I nodded and said, "Look at other scenes." I followed Wang Forensic Doctor and returned to the corridor full of blood, standing next to Zhang Nian's body.Forensic doctor Wang pointed to the surrounding rooms and said: "There are two bedrooms on the west side of the master bedroom we saw just now. The doors were locked from the outside. When I went in, I found that they were all piled up with sundries. There was no abnormality. There are 3 bedrooms on the east side of the bedroom. The one next to the master bedroom is a small room. It is usually the place where Zhang Peng, the son of Zhang Niannian, lives. Zhang Peng died in this room. Zhang Peng’s room is further east. A small room with only a toilet and a shower. It seems to be a simple bathroom. No abnormality was found after inspection. The easternmost room is also a bedroom. It is usually lived by Zhang Jiefang and Dai Lin, Zhang Niannian's parents. There are 3 The corpses are two old couples and a girl over 1 year old. The little girl is Zhang Niannian's daughter and has not yet been named. It seems that the old couple was killed while sleeping with the little girl. Zhang Peng's room The door to the bedroom is open, but the door to the east bedroom is locked from the outside." "After the criminals killed the old couple and the little girl, they locked the door when they went out, right?" I asked. Forensic Wang nodded. "This behavior is abnormal." I bowed my head and thought for a while, but couldn't find a clue, so I stepped into Zhang Peng's room. There were no extra traces in the room. An eleven or twelve-year-old boy was lying on his back on the ground with a pool of blood under his body.There was a broken mobile phone on the ground.I walked over and squatted on the ground, picked up the cell phone whose battery had been dropped, and said, "Is this cell phone for calling the police?" Forensic doctor Wang nodded. Walking into the bedroom on the east side, the scene was sealed for a long time, and the smell of blood was stronger, and it made people retch. The beds at the scene were basically stained with blood. The old woman and the little girl sleeping on the side of the bed near the door were lying quietly on the bed, their clothes stained with blood.The inside of the bed was empty, and Zhang Jiefang lay prone on the ground inside the bed, and the clothes on his back were completely soaked in blood. I walked to the side of the corpse and briefly looked at the surface of the corpse.There was a tear in the clothes on the chest of the old lady Dai Lin. I pressed her chest lightly, and the blood gushed out from the tear. "The old lady was stabbed in the chest." As I said, I checked the little girl's body. There were splattered bloodstains on the wall around the little girl's neck and on the back of the bed. I turned over the little girl's neck and found a large tear formed by stabbing and cutting. When I turned her neck over, the blood was still there. Slowly flow out from the breach. "It's a fucking beast!" Dabao, who had been following me silently, gritted his teeth and said, "A child who is only over one year old has the heart to do it!" I was also angry, so I didn't speak any more, and walked to Zhang Jiefang's side silently, and looked at Zhang Jiefang's injuries. "He has a lot of wounds on his back, it's hard to see clearly here, prepare to take him to the funeral parlor for further examination, brother." I straightened up and asked forensic doctor Wang for advice. Forensic doctor Wang nodded, took off his gloves, and took out the walkie-talkie in his pocket: "Get ready, let the comrades from the funeral home come up and drag the corpse." After watching this appalling scene, I walked out of the house and took a deep breath to calm down my grief and indignation.I raised my wrist to look at my watch. It was almost 11 o'clock. I turned my head and said to Forensic Doctor Wang, "Let's go to the funeral parlor." "Aren't you going to have lunch before you go to work?" "No, I can't eat. I'm impatient. Let's go." I shook my head. At this time, I saw Lin Tao also had a sad and angry expression on his face. He walked out of the scene, walked outside the cordon, took out a cigarette, squatted on the ground and smoked silently by himself.I saw that the comrades in the funeral parlor were still busy, so I walked up to Lin Tao, took out a cigarette, lit it, and said, "How are you doing, do you find any traces?" "After eliminating the shoe prints of the deceased, 110 policemen, and 120 emergency personnel, a blood footprint was found at the scene, which was initially judged to be left by criminals." Lin Tao said, "This blood was found in the three scenes with corpses." Footprints. There are also a large number of such blood footprints in the corridor. However, the general direction is from the east bedroom to the master bedroom, and then from the master bedroom to the child's bedroom, basically showing the trajectory of criminals." "Are there any special marks? Like fingerprints?" I asked. "No, a lot of glove prints were found, and it is certain that the crime was committed with gloves on." Lin Tao said, "Also, such footprints were found on the back of the elderly male deceased." "Hmm." I nodded, "The wounds on the back of the elderly deceased were dense, which should have been formed in a fixed position. If you say that, you can be sure that the murderer stepped on Zhang Jiefang with one foot. Messed up." "It's so cruel and inhuman." Lin Tao said, "It's simply inhuman." I nodded and said, "Keep working hard here, I'm going to the funeral home." Leiying City Funeral Home is a brand new funeral home. When the funeral home was rebuilt, the Public Security Bureau acquired a piece of land in the funeral home and built one of the best forensic autopsy rooms in the province.There are two regular autopsy rooms, a high-corruption autopsy room, and a severe infectious disease autopsy room.Four dissecting rooms form a matrix, and the gates of each dissecting room are located at the four corners of the matrix, and the four dissecting rooms are connected by dedicated passages. Entering the gate of the funeral home, looking east, you can see the forensic autopsy center of the Leiying City Public Security Bureau, which looks like a Pentagon. Walking to the door of the regular dissecting room, I found six mortuary beds parked in the central square of the matrix composed of four dissecting rooms, and there were white corpse bags on the beds.The yellow body skin and the dark red blood stains on the inside of the white body bag made people feel eerie.I simply divided into groups. Dabao led a group of two young forensic doctors from the Leiying City Public Security Bureau, and forensic doctor Wang led a group of the other two young forensic doctors from the Leiying City Public Security Bureau. Carry out autopsy examination, which improves work efficiency and can obtain key clues and evidence at the first time.And I wore an anatomy suit and shuttled between the two dissection rooms, becoming a bridge between the two groups of forensic doctors and sharing the information obtained during the autopsy. The autopsy work is carried out in order of "from easy to difficult".In the first batch of autopsies, two autopsy rooms conducted autopsies on the bodies of two children at the same time. The injuries of the two children were very simple. There was one stab wound on Zhang Peng's chest and upper arm respectively. A small crack formed on it.The wound on Zhang Peng's upper arm is also a penetrating wound, which should be a resistance injury, that is, when Zhang Peng resisted the murderer's knife, he was pierced through his upper arm. Because of the severe pain, he gave up resisting and was stabbed through the heart by the murderer. The little girl's eyes were closed tightly, and there was a huge stab wound on her immature neck, and her shirt and chin were covered with splattered blood.The so-called stabbing wound refers to that after the knife penetrates into the human body, the knife is not pulled out vertically, but obliquely, so the skin around the wound is cut open, and the wound appears to be very huge.The little girl's common carotid artery and veins were completely severed, and the body spots were faint because her blood was basically drained. It is extremely sad and indignant that a child was brutally murdered.After examining the corpse, the forensic doctors carefully sewed up the dissection wound and put the corpse into the freezer without saying a word. The second batch of tests involved two female victims.The injuries of the two female victims were similar to those of the two children, very simple.There were three wounds on the old lady Dai Lin's chest, two of which were pierced by the sternum, but because of the protection of the sternum, the knife did not penetrate the chest cavity, so although two stab wounds were formed on her chest, the Not fatal.The other injury was exactly the same as the one on Zhang Peng's chest. The knife pierced into the chest cavity from the space between the ribs, punctured the heart, lungs and posterior pleura, and penetrated the entire left chest.This knife caused the heart to rupture, which can lead to immediate death of the deceased. Zheng Qian had only one stab wound on her body, which was also stabbed in the chest. The tip of the knife pierced into the chest cavity from the intercostal space, but the stabbing position was from obliquely above to obliquely below, causing rupture of the lungs and aortic arch.A knife wound was also found on the towel quilt that Zheng Qian held tightly to cover her chest. It seems that when Zheng Qian was holding the towel to cover her chest, the murderer pierced the towel quilt and the chest wall to death.Combined with the direction of the injury and the analysis of Zheng Qian's position sitting on the ground leaning against the bed, the murderer should be Zheng Qian who stabbed downwards while standing.The breach in Zheng Qian's aortic arch was not large, so she would not die immediately, but during the process of her gradual death, she still firmly grasped the towel to protect her chest. The old Zhang Jiefang's injuries were located in the forearm and back.There were three penetrating wounds on his forearm, it seemed that he had a brief resistance before being subdued.Zhang Jiefang was in a prone position at the scene, and blood footprints were found on his back, so we carefully examined Zhang Jiefang's back.After inspection, it was found that Zhang Jiefang had been stabbed four times in the back, three of which were pierced into the spine, which was not fatal, but the other stabbed into the chest cavity from the back side of the chest wall, also pierced the heart, which could lead to his immediate death. The body of the male protagonist, Zhang Nian, is full of scars. There are resistance wounds that run through the forearm, scratches and bumps from the fight, and multiple stab wounds into the chest and abdomen. However, these wounds did not hurt the internal organs. fatal.However, one knife stabbed deeply in his upper abdomen and chest. The knife in the abdomen pierced the liver, causing the liver to rupture and hemorrhage. The knife in the chest pierced the pulmonary vein, which also caused a large amount of blood in the chest cavity.The most eye-catching thing was on Zhang Nian's chest, where there were eight parallel, tiny exfoliations, neatly arranged.I took a closer look at these skin exfoliations, and I didn't know what was formed in what state. I was thinking about it, but forensic doctor Wang interrupted my train of thought. "It seems that Zhang Nian was the only one who fell to the ground and died because of excessive blood loss and exhaustion after the fight. The other victims were stabbed to death by the murderer for the sake of fish and meat." Forensic doctor Wang said. "Well, all the injuries on the six people were caused by thorns. Based on the comprehensive analysis of the width and depth of the wounds, it should be a knife." I said. "One person, one knife, this is basically certain. Because Zhang Peng made the call to 110 and claimed that a masked gangster broke into his home." Forensic doctor Wang introduced the situation of receiving the police. "This person is really vicious." Dabao gritted his teeth and said.Dabao is a person who hates evil and hates evil. From the moment he arrived at the scene, I heard him gnashing his teeth. "That's not what I care about." At this time, the autopsy work has been going on for more than ten hours, and we have worked from noon to night. I took off my dissection suit, rubbed my hungry stomach, and said, "I I always feel that there is something wrong with the degree of digestion of the gastrointestinal contents of the deceased." "What's the problem?" Wang Forensic has always been very interested in the subject of inferring the time of death that Master led me to study. "The stomachs of the two elderly people are empty, and the degree of digestion in the intestines is six hours after the last meal." I said, "But the degree of digestion in the intestines of the two young couples is six and a half hours after the last meal. The contents of the stomach and intestines of the four people have the same ingredients, so they should eat together." "There is no contradiction." Forensic doctor Wang said, "From the perspective of traces, there are only blood footprints from the old man's room to the master bedroom on the corridor. It can basically be concluded that the old man was killed first, and the young man was killed second." I suddenly remembered Lin Tao's introduction, nodded and said, "However, there was actually half an hour before and after, and I always feel a little too long." "Go eat, I'm going to have hypoglycemia." The young forensic doctor on the side interrupted our conversation. I couldn't draw any conclusions for a while, so I nodded and said, "Let's go, I'm hungry too, and I want to eat beef noodles." I lay on the bed in the hotel and looked at my watch. It was almost one o'clock in the morning.After dissecting the corpse, I hid in the room and looked at all the photos of the scene and autopsy, and listened to the alarm recording more than a dozen times according to the requirements of the task force.Unexpectedly, this creepy alarm recording drove away all my drowsiness. Instead, I forgot my tiredness and became refreshed. I lay on the bed again, staring at the ceiling, thinking that I must force myself to fall asleep. There will be heavy on-site review work tomorrow, and I need to rest.In the twilight that was about to fall asleep, the fragments in my mind were combined one by one, as if the whole process of committing the crime gradually became clear, and slowly, I fell asleep. Early the next morning, I was awakened by the nightmare. After getting up and washing, I knocked on the door of Dabao and Lin Tao's room.Dabao and Lin Tao had just finished washing, so we went downstairs together by coincidence, and drove to the Institute of Criminal Science and Technology of the Leiying City Public Security Bureau.In the research institute, Dabao, Lin Tao and I sat at the consultation table and carefully studied yesterday's scene and autopsy photos. At this time, Forensic Doctor Wang came in and said: "All the DNA results are out. Let me speak slowly, please remember. The sperm spot detected in the condom in the master bedroom and Zheng Qian's vaginal swab is Zhang Nian. Yes. The wiped blood stains on the ground in the master bedroom were found to be Zhang Nian’s blood. The multiple blood traces in the master bedroom were found to be the mixed blood of Zhang Jiefang and Zhang Nian. The dripping blood stains in the master bedroom were Zhang Nian’s blood. One year's blood. The blood footprints in the corridor from the east bedroom to the master bedroom were found to be Zhang Jiefang's blood. The blood footprints from the master bedroom to Zhang Peng's bedroom were the mixed blood of Zhang Jiefang, Zhang Niannian and Zheng Qian .The trail of blood coming down the stairs is a mixture of blood from multiple dead." "Then the whole criminal process of the murderer can be reconstructed." Dabao said, "The murderer should first go to the bedroom on the east side to kill the old couple and the little girl. The little girl's blood, but he stepped on Zhang Jiefang, so Zhang Jiefang's blood stuck to the shoes. After killing people, the murderer locked the door from the outside, then walked to the master bedroom, and killed Zhang Niannian and Zheng Qian, because she heard the child call the police, she went to the child's bedroom, killed the child and left." "I always feel that this is not a revenge-seeking murder." I opened my mouth, "According to the dripping blood at the scene, the blood belongs to Zhang Niannian, so Zhang Niannian should have stayed in this place for a while after being injured. .If it is seeking revenge and murder, why should he stay here after being injured? Why don't you just kill him and leave?" I think my idea is very novel, and I can speak amazing words. I didn't expect that everyone present did not show surprised expressions, but nodded one after another. Dabao said: "I agree with your opinion, we can see that Zhang Niannian has dried blood on his thigh, and the bleeding direction is from the front side of the leg to the back side, which should be formed by squatting. Bleeding. If it was standing, the blood should flow from top to bottom!" Lin Tao said: "I agree! Have you seen the light blood marks on the back of Zhang Nian's thighs and calves? That should be blood stains sticking to the back of his legs. The bloodstains squeezed between them formed shallow blood marks, which should prove that Zhang Nian squatted for a long time after he was injured." "This time may be close to half an hour!" I looked at the problems I had noticed, and everyone noticed it, and I was very happy, and said, "According to the time of death, the death time of the elderly is half an hour earlier than that of the young." "Your analysis is very reasonable." Wang forensic doctor said, "If there is a process of controlling the victim, and the control lasted for half an hour, then the biggest possibility is to force the deceased to ask for money, then this is a case of robbery and homicide! " "This will change the entire investigation thinking, and will completely adjust the judgment of the investigation deployment!" Forensic Wang emphasized, "We must have sufficient evidence to report to the task force." I lowered my head and thought for a while, and said, "That's right. I'm sending the photos to my master now." Through the online consultation system, I sent Master the autopsy and on-site photos of the case, and reported to him that our criminal technical department began to suspect the nature of the "homicide due to hatred" case, and asked for his help.An hour later, Master called back as scheduled. "So many of you are brainstorming, why are you still not confident?" Master said with a smile. "Because it will change the entire investigative thinking, we want to have more evidence." I said. "Isn't your evidence sufficient?" Master said, "Who kills for revenge will control the victim for so long? What purpose can it have? Especially in this kind of case where one person wants to kill six people, the criminal's psychology will only be The sooner you kill the better, how could it cause trouble? Moreover, after the murderer killed the old man and the little girl, he locked the door from the outside, what does that mean?" In fact, I have been thinking about the question asked by Master for a long time, but I have no idea. When Master asked me, my mind suddenly became clear. Did he cause the death of two elderly people? That is to say, the murderer’s purpose was to make the elderly lose their resistance and prevent the children from crying, rather than killing them with determination. The criminal’s purpose was in the master bedroom, and he could It means that he just wants to steal money, not kill people!" Master said: "Very good! Doesn't this explain the problem?" "Can you be sure that the deceased was controlled?" I was still not at ease. "Why not? The shape of the bloodstains you mentioned is already very telling." The master said, "And the male master has threatening wounds on his body, haven't you seen it?" The so-called coercion injury refers to the injury left on the body of the deceased when the murderer threatened the deceased.After being told by the master, I suddenly remembered that there were eight parallel and thin epidermal peelings on Zhang Niannian's body. I said, "That's right! Those eight epidermal peelings should be formed by the tip of the knife! Therefore, the murderer used the tip of the knife to touch, The process of resisting Zhang Niannian's chest is a process of intimidation! It is the process of asking for the location of the money or asking for the password of the safe!" After hanging up the phone, with Master's support, I became bolder: "Forensic Doctor Wang, please ask the special case team to advance the time of the special case meeting." At lunch time, everyone has not eaten yet.The special case team held a special case meeting in advance to listen to the investigation opinions of the criminal technology department. "After such a long scene investigation and autopsy, we have determined that this is a case of robbery and homicide." I ventured to say the opening remarks. "What?" Qiang Feng, the leader of the task force, member of the Standing Committee of the Leiying Municipal Committee, secretary of the Political and Legal Committee, and director of the Public Security Bureau, was surprised, and said, "Is there any evidence?" “有，我们发现死者在死之前有被控制的过程，控制过程长达半个小时之久，且男主人身上发现多处威逼伤。所以我们认为凶手的目的是找钱。”我说。 专案组立即议论纷纷，大家交头接耳，有同意我们意见的，有反对我们意见的。 “而且，”我补充道，“凶手杀完老人以后有锁门的动作，说明他不确定老人是否真的死亡了，他的目的不是杀人。” “如果是抢劫，现场一楼的保险柜为什么不去撬？”有侦查员问道。 “因为这个人根本就不掌握开锁、撬柜的技术，小偷也是技术活儿。所以凶手去杀人、控制人，去威逼、拷问，要的可能就是保险柜的密码。”我答道。 “现场有数万元现金，凶手并没有拿走，为什么呢？”又有侦查员问。 “因为促使凶手杀害张一年夫妇的，是凶手听见了张朋在隔壁打报警电话，这一点，我们大家可以从录音中听出来。”我说，“既然他知道张朋报了警，他还有时间翻找钱财吗？他肯定是立即杀完人就落荒而逃了，没有时间翻找钱财。不然，我们的民警到得那么快，肯定把他现场抓了。” “我同意这种说法。”有一名侦查员站出来支持我们的看法，“经过调查，我们发现张一年为人吝啬，是要钱不要命的主儿。” “是的。”汪法医插话道，“凶手杀完老人和小女孩，锁了门才去主卧室，这时候主卧室的人可能并没有发觉东侧卧室的人已经被杀，所以张一年存了侥幸的心理，虽然他已经被凶手刺伤，但伤情不重，他想拖延时间。” “我同意他们的看法。”省厅刑事技术处的梁处长说，“大家可能注意到了报警录音的一个细节。小孩称：来他家的是一个蒙面歹徒。小孩一定是从房间出来，偷偷看见了主卧室里歹徒在控制他的父母，于是报警的。关键是，既然是蒙面歹徒，多半就是为了侵财了。” “是啊！”又有侦查员站出来支持我们的看法，“如果寻仇，铁了心要灭门灭口，那么就没有必要蒙面吧。” 几个依据阐述完毕，专案组出现了意见一边倒，大家开始纷纷支持这是一起抢劫杀人案件。 “那就立即调整侦查部署。”强书记说，“一二三四侦查组立即转向侵财杀人调查，第五组继续死者家因果关系调查，要完全排除因仇杀人的可能，不能麻痹大意。” “侵财案件，难度就大了。”雷影市公安局刑警支队长说。 “难度不大。”我说，“虽然是侵财，但肯定是熟人作案。” 大家纷纷安静下来，听我阐述是熟人作案的依据。 “第一，如果不是熟人，他不需要蒙面。”我说，“第二，凶手并没有在财务室内翻找，说明他知道钱不会放在外面，只会放在那个他打不开的保险柜里。第三，他知道走廊东头还住着成年人，会对他造成威胁，所以他先去东头房间让可能是后患的两名老年人丧失支援张一年的能力，为了出其不意，他杀了小女孩，防止小女孩哭喊。第四，他知道小男孩报警后，杀完大人又去灭小男孩的口，而不是杀完大人就逃跑，是因为他怕小男孩认出他的身形。第五，案发后，很快咱们就组织了大规模排查路人和设置关卡的行动，但是没有发现身上有血的人，凶手身上肯定有大量的血迹，他之所以没有被发现，是因为他在附近应该有藏身之处。” 五点依据一说，大家都纷纷点头，表示认可。 “不仅如此。”汪法医接着说，“我觉得凶手很有可能就住在附近，而且很有可能是在张家打过工的人，才这么了解张家的内部构造。” “那就抓紧时间开展排查吧！”梁处长说，“以现场为中心，周边10公里，挨家挨户的人口都必须排查。” 侦查员们纷纷工作去了，我心里也踏实了许多。短暂的午休后，我又有了新的想法，我叫来了汪法医和大宝，把尸体的创口照片一张一张地翻动。 “你们看，”我翻到张解放后背创口的照片，说，“尸体身上的创口创道都是狭长的。这样的刀子不是制式匕首，通常是没有护手的。” “护手？”大宝问道。 “是的，制式的匕首都有护手。所谓的护手，就是隔离刀柄和刀刃之间的金属片。但是这种狭长的刀子通常都是有特别的用处，通常没有护手。”其实我自己是个刀具迷，大学的时候还私藏过管制刀具，后来被父亲发现怒斥了以后，才主动缴了公。 “没有护手能说明什么呢？”大宝问道。 我翻到几张照片，说：“戴林的胸骨被刺到几刀，张解放的脊柱被刺到几刀。这几刀，尤其是张解放后背的刀伤，方向都是垂直的，而且结合痕迹发现的脚印，凶手应该是踩住张解放的后背，从上往下捅的刀子。”我一边说，一边做着示范。 “既然是狭长的、没有护手、锋利的刀具，又从上往下直捅，且捅在了骨质上，那么，因为刀尖受阻，拿着刀的手会沿着刀的长轴方向往下滑，最终……” 大宝跳了起来，插话道：“明白了！你是说凶手握刀的手很有可能滑到刀刃上。那么这么锋利的刀刃碰到握紧刀的手，凶手的手可能会受伤！” I nodded. “可是，这又能说明什么问题呢？”大宝接着问道。 我拎起勘查箱，说：“叫上林涛，去现场看看就知道了。” 其实我是在找凶手有可能接触到的地方，如果凶手的手真的受了伤，那么他的手接触的地方就有可能留下他的血迹。虽然现场已经提取了200多份血迹点，但是对于满是血迹的现场，只是冰山一角，而且事实证明，这200多份血迹中，并没有发现凶手的DNA。 我们在现场仔细搜索了3个多小时，突然，主卧室墙壁上的一处血迹引起了我的注意，是一个类似五指印的血迹。 “林涛快来看看。”我说，“这是什么痕迹？” 林涛走了过来，用放大镜仔细观察了5分钟，得出结论：“这确实是一个五指印，是戴着手套的五指印。” “你看。”我指着五指印中食指的末端位置说，“这有往外喷溅的血迹。如果是黏附在手套上的血迹，因为迅速流动均匀，不可能因为挤压而形成喷溅血迹。” “你是说，有可能这喷溅状血迹是从手套里面被挤压出来而形成的对吗？”林涛说。 “是的。”我赞赏林涛的聪明，“这种血迹形态一看就是血液在手套内受挤压，才从手套破口处挤喷出来的。” “手套内的血，肯定是犯罪分子的血！”林涛高兴得跳了起来。 “我马上把这块血迹送去DNA检验，是不是，要让检验结果来说话。”我说。 送完DNA样本，我重新回到宾馆，此时林涛已经回来了，说：“又仔细看了很多处血迹，没有再发现类似的了。” 我点了点头，说：“等结果吧，别小看这一处血迹，说不准案子可能就会有重大突破了。” 怀揣着希望，我睡了一个无比踏实的好觉。第二天一早，果然梦想成真了。 汪法医敲开我的房门，摆了个很酷很幽默的姿势站在门口，说：“恭喜你，凶手的DNA真的给你找到了。” 汪法医敲门的时候，我还睡得正香，迷迷糊糊地听到汪法医这么一说，我立即清醒了。 “真的？”我高兴地大声喊道。 “新鲜出炉的消息，比专案组组长还快一步。”汪法医笑道。 “有了这样的证据，就可以认定凶手，为诉讼服务，最关键的是，我们有了物证，比较容易甄别犯罪嫌疑人了。”大宝从汪法医的背后冒了出来，看来他也得知了这振奋人心的好消息。 我们纷纷洗漱完毕，乘车赶往专案组，期望能听到更好的消息。 专案组坐满了人，侦查员们已经两天三夜没有睡过像样的觉了，一个个眼圈发黑坐在自己的位置上拼命地吸烟。有的侦查员则趴在桌子上打盹儿。 “很好，”梁处长说，“我们刑事技术部门发现了凶手的DNA，这是给专案组的强心剂，这个案子不怕破不了了。” “下一步是请各组侦查员汇报这几天的摸排情况，有无可疑的人员。”支队长在主持会议。 几个组的主办侦查员交头接耳交换意见以后，雷影市公安局重案大队大队长说：“经过几组侦查员夜以继日的摸排，目前满足熟人、在死者家打过工、住在现场附近的人员这3个条件的，有3个人。目前正在逐一排查，但是最可疑的是一名叫乔虎的21岁男子。” 主办侦查员一边把3个犯罪嫌疑人的照片递给我们传阅，一边说：“这个乔虎是住在现场500米外的乔江林的儿子，从小游手好闲，偷鸡摸狗，一年前在张家打工，负责在张一年各个店面之间调配运输婚纱和其他设备。后来因为盗窃店里的摄影器材未遂，被张一年开除，现在在省外的一家屠宰场打工。经乔江林反映，乔虎最近并没有回乡，但是经我们与乔虎打工的屠宰场联系，乔虎因为受不了粗活儿重活儿，已经辞职一周了。” “乔江林的话不可信。”梁处长说，“如果真的是乔虎所为，案后乔虎必然会发现市局组织了大规模的巡逻搜查，他最好的躲避场所就是自己家。所以，不能排除乔江林有包庇的嫌疑。” “其余两名犯罪嫌疑人赵亮亮、林家翼的工作仍在继续，这两个人目前都还在雷影市，表现也比较正常。”主办侦查员说，“两名犯罪嫌疑人的血和乔江林夫妇的血都已经采集，开始进行检验，希望能比对成功。” 我看已经摸排出了非常可疑的犯罪嫌疑人，DNA比对正在进行中，顿时放心了许多。专案会结束后，我和林涛、大宝回到房间，继续研究现场和尸体情况，期望能有新的发现。 我拿出了纸笔，逐个儿记录了每具尸体上的每处创口的长度、深度，慢慢地，整理出了一套完整的数据：长0.1厘米，深0.2厘米；长1厘米，深1.3厘米；长2厘米，深3.2厘米…… “你这是做什么？”大宝问道。 “你看看。”我说，“创口的长度就提示了刀刃的宽度，创口的深度就提示了刀刃的长度。在特定的刃宽下有特定的刃长，我们就可以推算出一把刀的模样。” 经过仔细的核对、绘图，我们用了一个下午的时间，描绘出了一把刀的模样。 这是一把尖刀，刀刃的总长有15～16厘米，刀尖非常尖锐和锋利，刀身狭长。整个刀刃纵截面呈一个三角形。 “这种形式的刀，还真不多见。”我说，“估计是有特种用途的。” 就在这时，一阵急匆匆的敲门声把我们从对刀子的思考中拽回了现实。 汪法医站在门口：“不好的消息，经过检验，排除赵亮亮、林家翼的作案可能，经过对乔江林夫妇的血比对，也排除了他们的儿子乔虎的作案可能。” 这仿佛是晴天霹雳，好不容易摸排出来的3名犯罪嫌疑人却一股脑儿全部被排除了，大家显得比较沮丧。此时已经很晚了，大家顿时感觉无计可施，垂着头各自回房间睡觉，希望睡着了可以排解这郁闷的情绪。 “别急，我相信侦查员还能继续排查出新的犯罪嫌疑人，我们一定可以破案的。”汪法医看大家的情绪都很低落，安慰道。 我看大家都回自己的房间，百无聊赖，于是拨通了师父的电话，把前期的情况和师父做了汇报。师父说：“你总结出刀的模型这个很好，但是你并没有把这么好的想法用到实际用处。下一步，我觉得你应该去寻找这样的刀。” “寻找？”我说，“天哪，那去哪里找啊？” “很多事情可能没有你想象得那么复杂。”师父笑道，“首先卖刀的地方比较集中，你跑几个点就可以以点概面发现个大致情况了。如果仍无法找到，你可以去一些可能用到刀具的厂子里找，厂子的刀具可能都是特制的，与众不同。” 我拿出纸笔，按照师父说的几种厂子，逐一做了记录，做好明天去一个一个厂子里找的准备。 迷迷糊糊睡了一夜，第二天早晨，我和大宝就开始走遍全城有可能售卖刀具或者可能有特种刀具的地方进行查探，希望能在路边摊儿、工厂矿发现相似的刀具，说不准就能确定凶手的职业，或者能发现他买刀的地方。跑了整整一天，皇天不负有心人，终于让我们找到了这样一把狭长、锋利、尖刃而且纵截面是三角形的尖刀。找到和我们推断一致的刀具后，我们出具了证明，借了这把刀，立即风驰电掣赶往专案组，参加专案会议，希望能听见新的好消息。 “你们可以确定是熟人吗？可以确定是侵财杀人吗？”在专案组门外就听见了强书记洪亮的声音，看来强书记在质疑我们刑事技术部门前期的推测了。 “目前侦查部门已经全力以赴，再也没有发现符合初始设定条件的犯罪嫌疑人。”强书记接着说，“目前看来，问题就出在初始设定条件的问题上，是否真的是侵财杀人，是否真的是熟人作案，这是本案能否出现新的突破口的关键！” 我悄悄走进专案组，找了一张列席位置坐下，默默地思考我们的前期判断到底有哪些是站不住脚的。 “还有一种可能。”梁处长突然幽幽地开口了，“目前排除了赵亮亮和林家翼的作案可能，排除了凶手是乔江林夫妇所生的儿子，但是并没有排除乔虎。” 这一句话让侦查员们听得莫名其妙，但是我一下子就明白了梁处长的意思。 “对！”一语惊醒梦中人，这一句点拨，让我排解了心中所有的矛盾，我忍不住叫了出来，“梁处长说得对，说不准乔虎不是乔江林的儿子呢？说不准是抱养或者过继的呢？” 侦查员们都“哦”的一声明白过来。梁处长接着说：“之前我们说了，乔江林很有可能会包庇藏匿他的儿子，那么如果乔虎真的不是他亲生的，他也肯定不会告诉专案组这个事情。毕竟一把屎一把尿拉扯这么大，作为一个没有多少文化的父亲来说，很有可能会犯这个错误。” 强书记说：“但这都是推测，毕竟这样的事情也太少见了吧。如果没有依据，我们不可能让整个专案组的精力都从摸排转化成抓捕。” “不知道我这点依据行不行。”我站了起来，拿出了我画的刀的模型和刚才借到的尖刀，说，“我觉得这个乔虎是非常可疑的。大家看这是我根据6具尸体上的创口形态推测描绘出的凶器的模型，而这个是我刚刚走遍雷影市，借到的一把尖刀。大家看看，是不是如出一辙？” 我看见大家都在默默点头。 我接着说：“这把尖刀，我走遍全市，也没有找到一把。但是当我走进市肉联厂的时候，发现到处都是这样的尖刀。这种尖刀是杀猪用的。大家别忘了，乔虎辞职前，就在屠宰场工作。” 我一说完，全场都发出“哦”的赞同声，随后是议论纷纷。 梁处长清了清喉咙，等会场安静了一点儿后，说：“凶手杀人，刀刀致命，开始我就觉得可能是和屠宰场之类有关的工作人员干的。” 强书记低头想了想，说：“调查乔江林的情况了吗？是不是本地人？” “乔江林的父亲是本地人，但是乔江林不是在本地出生的，在他30岁左右的时候，乔江林的父亲去世，他是举家带口集体迁徙到本地继承祖宅定居的。”主办侦查员说。 “就是说，乔虎不是在本地出生的？”强书记拍了桌子，说，“这个情况怎么不早说？下一步迅速去乔虎出生地，查清乔虎到底是乔江林亲生的，还是领养的。” 看见强书记转变了侦查部署，我稍微放了点儿心。 刑事技术的工作基本完成了，我只能枯燥地躺在床上，反复思考这个案子的全部推断，有没有漏洞，有没有矛盾点。 好在刑侦部门行动迅速，如同天兵天将一般。在我枯燥等待的3天里，他们不仅查清了乔虎确实不是乔江林亲生的，而且迅速在1000公里外的甘肃省抓获了潜逃中的乔虎。DNA检验正在做，侦查员们也不急于审讯，因为当侦查员们抓获乔虎的时候，发现他的右手包扎着一团纱布，纱布上还透出殷红的血迹。 案件侦破后的一个月，我都无法从这起命案中走出来。血腥的现场、一家六口的惨死让我无比心痛，梦中都会不断浮现出死者惨死的面孔，让我夜不能寐。 这一天，师父把我叫到办公室，说：“怎么，看你最近情绪不对头啊？” “哦。”我低着头抠着指甲，说，“灭门案太惨了，看到一家人惨死，我好像有心理阴影了。” “你现在已经是一名可以独当一面的法医工作者了，但你现在还缺一样本事，就是学会自我心理调节，这是每一个法医必须掌握的本领。”师父说，“社会上的人形形色色，犯罪不可避免，我们的职责就是预防、打击犯罪。相信法制越来越健全，技术手段越来越高超，犯罪分子逐渐就都会无处遁形的。我们的铁拳硬了，犯罪自然就少了，握紧拳头，努力工作吧。” 我点了点头，说：“没事，大的交通事故都经历过，也有过心理阴影，不过我都调节好了。第一次碰见这么大的命案，我确实有点儿不适应，也确实有些郁闷。不过请师父相信，我没问题的。我们的目标是人间太平，对吧？” 师父微笑着点了点头，说：“憎恶犯罪分子，同情受害者，这是法医们都有的情结。我们干的是一般人干不了的职业，老祖宗也自嘲我们这个职业是鬼手佛心。你的鬼手技术3年前已经通过了考验，今天我又看见了你的佛心，我很欣慰。” 师父拉开抽屉，拿出一个精致的小方盒扔给我，说：“这是厅政治部让我转交给你的礼物。” 我满怀疑惑，慢慢打开小方盒，呈现在眼前的，是一枚亮闪闪的功勋章。
