Chapter 12 Tenth Case Dead Christmas
In a blink of an eye, it was my first Christmas since I started working.There are Christmas trees and colorful lights everywhere on the street. The happiest thing is that I brought my girlfriend Bell to the provincial capital.
This girl, Ling Dang, is a bit stubborn. Like me, she also graduated from a forensic medicine major.I managed to persuade her to give up her forensic work and become a doctor—of course, this was a bit selfish, and it was enough for me to be busy at the scene all day.
In the evening, I happily took the bell to a Korean barbecue restaurant for dinner. Unexpectedly, the first pot of meat was just cooked when the phone rang suddenly.I frowned, thinking to myself that it must not be some kind of case, and took out my phone nervously from my pocket.I was really afraid that something would happen, and the word "Master" was displayed on the screen of the mobile phone.
"Where is it?" Upon hearing Master's habitual opening remarks, I vaguely felt that this romantic dinner was a waste of time.
"I'm... eating, Master."
"I'll give you 20 minutes to gather at the entrance of the lobby."
"Another case?"
"Three people were burned to death in Qingxia County."
"Burn to death? Abnormal death, we also want to go?" The murder case that has been running for half a year, the abnormal death incident is already a piece of cake for me, I hope it is not a big event that must be done.
"Three people died, we must be there, no matter what the nature is. Besides, can you guarantee that the corpses are not burned after death?" Master said, "Stop talking nonsense, and arrive on time."
When I heard about a case before, I would be full of joy, but after hanging up the phone this time, I was full of guilt.
"Go ahead, I'll take a taxi home by myself later." Sister Ling Dang, who was still smiling just now, her eyes were a little red now.During the days we were together, we have always been more apart and less together.But after all, she also graduated from the Department of Forensic Medicine, and her political quality must be very high, so she wiped her face and comforted me with a smirk, "Go, go, next time I will kill you again!"
Twenty minutes later, Master and I were already in the car heading to Qingxia County, more than 200 kilometers away. The night was dark on the country road, and there was almost nothing to see except for the light from the car lights.It was quiet all around, and the lively Christmas atmosphere in the city had already been left hundreds of miles away.
Suddenly there was a brake, the car bumped a bit, and the driver, Master Ruan, yelled: "Ouch, I'm sorry!" I was startled, looked out the dark window, and asked, "What's wrong?"
"A kitten crossed the road, and it didn't have time to brake. It seemed to be run over." Master Ruan said.My heart twitched, and I silently mourned for this unlucky kitten. A little life was lost in such a way. I don't know what kind of tragedy it will be at the scene we are going tonight.
"Christmas Eve is not safe." The master who had been silent all this time sighed.
At 10 o'clock in the evening, we finally arrived at the scene of the embarrassment.
This is a small courtyard with a single gate, and there are no residents for several miles.There are two brick houses in the courtyard, both of which have lost their roofs, and more than half of one of them has collapsed.There was water everywhere in the yard, and it seemed that the two fire trucks outside the door took a lot of effort to put out the fire, and the house was still billowing with black smoke.
The door has been cordoned off, and the headlights on the roof of the criminal scene investigation vehicle illuminate the scene brightly.Several criminal policemen in plain clothes are separately questioning the firefighters and villagers who participated in the fire fighting.
"Let's briefly understand the situation first." Master frowned and looked at the bad scene, and said, "This kind of scene is more difficult to investigate, it is a mess, and the firefighting process also destroyed some traces."
The master simply walked around the perimeter of the cordon, with his hands behind his back, and while wiping the mud off his shoes, he walked to the informant to ask about the situation.
"I live on the other side 3 miles away from here." The reporter pointed to the distance enthusiastically and said, "At 5 o'clock in the evening, when it was getting dark, I saw smoke here, and then I saw There was a fire. At first I thought it was something burning, but then I found something was wrong, the fire was very big, so I quickly called 119. After calling the police, I ran here to see that the house was burning, and I couldn’t get in. , called 'Lao Xia, Lao Xia', and there was no movement at all. Later, I heard from the firefighters that Lao Xia was burned to death." The reporter was an old man in his 50s. His eyes were red and swollen, as if he had been crying for a long time.
It seems that Lao Xia is the owner of this small courtyard, and the reporter obviously has an extraordinary relationship with Lao Xia.
"How many people are there in Lao Xia's family?" Master asked casually.
"Lao Xia's son and daughter-in-law have all gone out to work, and his wife has passed away. He is alone with two young grandchildren, one is 6 years old and the other is 4 years old. It is said that they were all burned to death."
"It seems that his family's conditions are not bad, right?"
"So-so, but he's very frugal."
"Good leader," at this time, the local criminal police chief walked out of the scene, "you came here so fast. Preliminary inspection, one old and two young, 3 lives. The fire department is looking at the cause of the fire. It is not clear whether it was burned before death. Dead or cremated. The body was burned badly. Technicians are looking at the scene, but no valuable clues have been found yet.”
"Who found the body?" Master asked after shaking hands with the captain of the criminal police.
"After the fire was extinguished, a firefighter came in to clean up the scene and found three people lying on their respective beds, all of which were badly burned. He contacted us, and we reported it to the provincial department as soon as possible. I just didn't expect you Arrived so fast, hehe."
"Lying on their respective beds?" Master rubbed his chin. "Go to bed at 5 o'clock? And sleep so soundly that you don't even know it's on fire?"
"Well, we also think it's suspicious, but we still need an autopsy to clarify the nature."
The master didn't answer, he set off the security tape and walked into the scene.
I went in with Master, and the place had been burnt beyond recognition. There was a strong burnt smell, and I couldn't tell whether it was wood or human flesh.
"Master, be careful." Most of the collapsed roof looked empty, with sand falling down from time to time, and I walked in fear, "This house may collapse at any time."
"When we look at the scene, we will encounter all kinds of dangers. There are sites full of poisonous gas, sites that may explode at any time, and of course houses that may collapse." Master nodded and said, "You have a very strong sense of protecting yourself. Okay, but you can’t ignore the scene just because it’s dangerous, it’s your responsibility.” Master took the safety helmet handed over by the technician, put it on, and walked into the scene.
We walked into the first house that hadn't collapsed but had no roof, and found that it was the family's kitchen and warehouse.There are four empty bowls on the stove, and there is a pot of noodles in the pot.The blackened walls in the kitchen were all soaked, and the ground was also full of water.With nothing to investigate, Master and I walked into another half-collapsed room.
This should be a bedroom, with two beds, and furniture like tables and wardrobes under the collapsed bricks and tiles.As soon as I walked into the house, two bricks suddenly fell head-on, which really shocked me.Fortunately, the three corpses were all lying on their own beds, and they were not crushed by the fallen bricks.As he approached the corpse, a strong smell of burnt meat came to his face.
I subconsciously rubbed my nose.I have been working as a forensic doctor for so long, and I have developed a habit of rubbing my nose vigorously when I encounter scenes and corpses with obvious odors.I don't know if it's a psychological effect or a real effect, but after rubbing my nose, I usually don't find the smell unbearable.
Of course Master knew this habit of mine, and asked me with a smile, "No way, it's okay to say that a rotting corpse smells bad, but a burned corpse doesn't smell bad, and the meat smells good even when it's cooked."
For some reason, Master's words made me want to throw up, and I suddenly remembered the roast meat that I wolfed down tonight.
The clothes on the corpses have basically been burned clean, the skin has been charred, and the postures of the three corpses are all boxing postures.
"The corpse is in the shape of fist fighting," I said. "The book says that the shape of fist fighting is a sign of a corpse that was burned to death in life."
"It is better to have no books than to believe in books." The master said, "The corpses burned after death are often in the shape of fists. As long as the fire is fierce, the soft tissues will be heated and contracted quickly to form fists."
I nodded, put on my gloves and squeezed the old corpse's arm.There was a "click" on the arm, and a piece of burnt skin fell off.
"It's burning badly," I said.
"The roof has collapsed, of course it's serious." While observing the ground, the master rubbed his toes against the hard soil, and said, "The carbonization is the most serious here. Send it to the Municipal Bureau for physical and chemical inspection to see what kind of accelerant it is.”
Master is not only a criminal investigation expert, but also an appraisal expert at the scene of a fire accident. He is also very experienced in the investigation of the fire scene.
The technician scraped the ashes on the ground according to Master's instruction.Master looked left and right, then at the drenched wall, and said, "Take the body to the funeral parlor for autopsy."
"It's almost 12 o'clock, your blood pressure is a bit high, why don't you go back to the hotel to rest, and see the corpse tomorrow?" The captain of the criminal police said to Master with concern.
"Solve the case, can you wait?" Master took off his helmet and got into the car first, "Go to the funeral parlor."
When we arrived at the funeral home, we were all dumbfounded.In Qingxia County that year, the autopsy room had not yet been built, and the funeral parlor was dark and quiet everywhere. Only when we entered the morgue, did we finally hear the sound of the mortal world, which was the freezer compressor. The roaring sound.The morgue was not lit, and the moonlight came in from the window. There was no romance under the moon, but it felt a little more eerie.
"Can you find a way to illuminate it?" Master asked.After all, one of the necessary conditions for autopsy is to have enough light.
"There are two ways. One way is to use the headlights on the roof of the survey vehicle. They are very bright, but a tank of gas can only illuminate for 7 hours. Now we only have half a tank of gas left." Forensic doctor Shao from Qingxia County said, "There is also a power strip to connect a light bulb to the outside, but the brightness is limited."
"We'll definitely be busy in three hours. Let's connect the light bulb. It's best to find one with a large wattage, and then use a portable survey lamp to assist in lighting." Master said while looking for a place in the open space behind the morgue. The 3 mortuary beds are also convenient for dissection.
"Three hours must be too busy." Forensic doctor Shao swallowed.Master's implication is, don't sleep tonight.
Soon, simple lamps were set up by local forensic doctors and trace inspectors. They used the lights on the construction site, which were very bright but also very hot.At the same time, the corpse was also driven back by the master of the funeral home.
"Are you all right? I'm leaving." The master of the funeral home yawned and said.
"Find us three corpse beds, so we don't have to squat on the ground to dissect." Master said.
"Oh, just wait." The master of the funeral home seemed very impatient, "Can't we do the autopsy tomorrow? It's so urgent, it's already past 12 o'clock."
"The family members of the deceased must think it's not acceptable." Master said quietly.
The corpses were quickly placed on three corpse beds lined up.As soon as the body bag was pulled open, a burning smell quickly permeated the sky above the open space.Although my stomach has already been emptied, I still feel sour when I think of the barbecue that I ate at night.
"The first step is to determine whether to burn the body before death or to burn the body after death, which plays a key role in determining the nature of the case." Master obviously wanted to check my theoretical foundation, "What is the difference between burning the body before death and burning the body after death? "
"Look at the burns on the skin, whether there are any life reactions, whether there are erythema and blisters." I thought to myself that such a small problem would also confuse me?Although I reacted quickly, I was also scolded very quickly.
"Stupid! What's the life reaction after being charred?" Master said.
"I haven't finished yet." I was very unconvinced, "The key is to see if there is any soot and charcoal in the respiratory tract of the deceased."
"Well, it depends on whether there are thermal burns in the respiratory tract and lungs. At the same time, it depends on whether there are signs of carbon monoxide poisoning." Master emphasized, "Many people died of carbon monoxide poisoning before inhaling soot and charcoal in the fire scene. Such a body would be mistaken for post-mortem cremation because no soot was inhaled."
I nodded, reached out to touch the corpse, and with a "click", another piece of burnt skin fell off, exposing the scarlet subcutaneous tissue, which was extremely eerie under the strong light.
"Let's look at the children first, the easy ones first and then the difficult ones." The master said, walked to the corpses of the two children, and began to examine the corpse watches.Although the corpse form has been completely carbonized, the examination of the corpse form is also indispensable.Neither an autopsy nor an autopsy revealed obvious trauma.I clamped one side of the trachea of the corpse with a hemostat, and gently cut open the very immature trachea of the child with a cleaned scalpel. The wall of the trachea is very thin. Surprisingly, the entire trachea was full of soot, and the thermal burn was also very obvious.
"It turned out to be burned to death!" I said in surprise.
The master frowned and said nothing.Soon, as if he had thought of something, he quickly cut open the child's scalp with a scalpel.The child's scalp has been burned incompletely, and it is very brittle.It is impossible to tell whether there is a hematoma under the scalp, but after cutting the scalp, we found that the child's skull had been broken, and several pieces of the skull adhered to the scalp and fell off when Master peeled off the scalp, revealing the red and white brain. organize.
"There is a trauma to the head!" Forensic Shao said.
"No way." Although I have never seen such a burnt corpse, I still have a good theoretical foundation. "The book said that the skull cracking phenomenon often occurs in burned corpses, which is caused by the embrittlement of the skull and swelling of the brain tissue after burning." caused by other reasons.”
"Yes, corpses burned to this extent, especially infant corpses, usually have the phenomenon of separation of the skull bone sutures, or even cracking of the skull." Master approved my point of view, "However, judging from the color of the brain tissue , must have been traumatized."
Master compared the reddish parts of the brain tissue and carefully observed the marks of skull cracks.Suddenly, the master's eyes lit up: "Let me just say, this cannot be an accidental fire at all."
Hearing what Master said, we all turned our heads to look at it.
Master pointed at one of the many fracture lines where the skull cracked with the hemostat, and said, "Look, the skull at the edge of this fracture line is sunken inward. We know that the fracture line of the skull crack in the burnt corpses is caused by Formed by embrittlement and expansion, the fracture lines are all linear, and it is absolutely impossible to sag inward, right?"
We all nodded.Master went on to say: "The fracture line should be a depressed fracture line. If the fracture is depressed, there is bleeding in the brain tissue, and there is no concussion injury, so it can only be caused by the direct action of external force."
"You mean to say that the child was burned to death after being knocked out?" Forensic Doctor Shao asked.
"Yes, if I guess correctly, the situation of the other child is the same as this one." Master said.
Soon, we finished dissecting the corpse of another child. As Master had guessed, the trachea was full of soot. There was no other trauma on the whole body, but among the traces of skull cracking, several fracture lines were sunken inward.
"It seems that the murderer is very confident." The master said, "He made the children lose their resistance first, and then burned them to death. He didn't worry that the children would come back to life. So I think the combustion aid he used should be gasoline or the like. Burning things, he poured gasoline directly on the dead."
"Didn't you say that the fire started in the middle of the room?" Forensic Doctor Shao asked.
"Yes, there should be a container for accelerant, which is also the point of fire, and the fire quickly spread to the corpse." Master said, "Let's go to the scene to see the ashes later."
Master looked up at me, and I was just standing aside and thinking.Master immediately understood what I was thinking: "Why, you still don't believe it's a murder case? Then let's look at the body of your lord, maybe there will be unexpected gains."
We examined Lao Xia's body more carefully.After opening the chest cavity, I vaguely found that his lungs were not like the lungs of the two children, and there was no burn at all.I picked up the scalpel and prepared to cut the trachea.Master stopped me and said, "Be careful with this, stick out your tongue."
Tongue out is our commonly used abbreviation, which means to take out the tongue in the mouth from the neck, and then the whole set of internal organs can be separated from the body.This method is usually used when testing is required, and all visceral sections are taken for diagnosis under a microscope.
I understood what Master meant. He wanted to observe the condition of the deceased's throat more carefully.I used a scalpel to cut off all the muscles along the jawline of the corpse, then inserted a few fingers from the neck into the mouth of the corpse, pulled out the tongue, and then cut off the soft tissue of the posterior pharyngeal wall, and pulled out the tongue smoothly .
Master smiled and nodded, approving my skillful technique.
After I separated the upper airway and lungs of the corpse from the chest cavity, I was surprised to find that there was no trace of soot or burning in the throat of the deceased.
"Look, this is cremation after death. The trachea should also be clean." Master said.
After all, the master has rich experience.Open the trachea, sure enough, the entire trachea wall is clean, no abnormalities.
I raised my arm and wiped the sweat from my forehead with my upper arm, breathed a sigh of relief, and said, "I was hit by what Master said, it's really a murder case."
Although Lao Xia's scalp was also scorched, his skull was not severely burned, let alone cracked.After incision of the scalp, we found that there were several depressions in the left occipital and left top of Lao Xia's skull, and the intracranial injury was even more severe.
"It is consistent with the injury pattern of a child." Master said, "Use a blunt instrument to hit the head."
In order to find more traces, I carefully wiped the skull of the corpse with gauze, trying to wipe off the periosteum, so as to better observe the shape of the depressed fracture, thinking that I might be able to deduce the shape of the injury tool in more detail.
But the master had already made up his mind. He pondered for a while, and said to the forensic doctor beside him: "It takes a certain amount of time for a craniocerebral injury to cause a person's death. From this point of view, the murderer should have hit Lao Xia on the head first, causing him to fall unconscious. Then dragged him into the burning scene and put him on the bed. After discovering the two children, he was beaten with a blunt instrument to make the children unconscious. During this process, Lao Xia died of severe brain injury, but the child was only in a coma. When the fire started, Both the dead Lao Xia and the living but comatose child were burned to death."
Everyone nodded.This can explain why the elderly and children were burned at the same burning site, but they were burned after death and burned to death during their lifetime.
While Master was analyzing the case, I vaguely discovered something new.I called the trace inspector who was in charge of lighting to come over, and used a strong flashlight to illuminate the center of Lao Xia's depressed skull fracture.At this time, I had wiped off the periosteum of the deceased's skull, revealing the white bones and clear concave fracture lines.
Suddenly, my eyes lit up and I said, "Master, look, what is this!"
Master leaned over.The strong flashlight illuminated the skull from which the periosteum had been stripped, and at the same time clearly illuminated a faint blue trace in the center of the skull fracture depression.
"What is this?" I pointed at the blue mark with the hemostat, "How could there be something blue? The clothes are all burnt, it can't be the residue of clothes."
"Could it be contamination when you peeled off the periosteum?" The master took the cranium, looked at it carefully, and checked the deceased's clothes for blue things.
"No." I took the hemostat and pointed to several other depressed fractures, "There are 7 depressed fractures in total, and there are blue marks in 5 of them."
The master looked carefully at the other depressed fractures and frowned.
"Besides, I tried it just now." I gently rubbed the tip of the hemostat against the blue mark at the center of the fracture, "It won't be wiped off with light rubbing. It should be pressed into the bone."
"Hmm." Master nodded and said, "It's really strange that there are traces of blue here. What do you think?"
"The blue substance is flaky and has strong adhesion. I think it should be a paint-like substance." I looked again and continued, "It can be pressed into the bone, and it should be pressed into the bone with a blunt instrument." The paint was embedded in it. Combined with the fact that several of the deceased were hit on the head by a blunt object, so according to this blue substance, I think the biggest possibility is that the murder weapon was painted with blue paint, and the murder weapon hit the skull. The blue paint on it was pressed into the bone of the skull."
Master pondered for a while, then nodded: "This discovery of yours should be our biggest gain tonight." Seeing the joy on Master's brows, I know that his words are the biggest achievement for my work tonight. affim.
It took another nearly an hour to sew up all the incisions and tears on the corpse before we took off our dissecting suits, washed our hands, and ended the night's work.I raised my wrist and looked at my watch. It was already 5 o'clock, and our feet were already numb in the cold wind.I rubbed my hands and stomped my feet desperately, hoping to promote blood circulation in the extremities of my hands and feet.
The trace inspector standing aside swiftly put away the video recorder, obviously dissatisfied with our lingering, he shrugged, stomped his feet, yawned, and said: "The leaders of the provincial department are dedicated, and the corpses are burned to the ground. After seeing this state, is it meaningful for you to still stitch it up so seriously? You can’t hold a memorial service.”
This sentence aroused my strong disgust. I frowned and said, "The dead also have dignity." This time, I said this sentence before Master.
Master smiled and nodded, as a sign of approval for my words and the outstanding performance and great discovery that night.
"What should we do now?" The trace inspector scratched his head and asked.He was obviously embarrassed by one of my words.
"What else can I do? Go to sleep." Master yawned and said with a smile, "Forensic doctors are human beings, not gods, so they need to sleep. Go back and rest, and attend the special meeting at 9 o'clock."
Forensic medicine is not a god, but it does what a god can do, I thought unhappily in my heart.Sleeping for three or four hours is better than not sleeping at all.I want to think about it, but I know Master's temper, and he is absolutely meticulous about the case.The special case meeting is also very important for the forensic doctor. Only through the communication at the special case meeting can the forensic doctor understand the situation detected by the criminal police and the investigators understand the forensic inference. Only through sufficient communication can we ensure that the case can be solved quickly and accurately.So I didn't say a word, and got into the car silently.As soon as I got in the car, I felt drowsy all over the car, and Master snored before me.I went back to the hotel and took a quick shower, then fell into a deep sleep.
The short sleep of less than 4 hours after tiring work is the most uncomfortable, especially the moment I was woken up by the doorbell, I felt thousands of big hands pressing me on the bed.I didn't sleep well, because the dream was full of blunt blue objects floating by like a movie.It's a pity that a dream is just a dream. When I wake up and think about it, I still don't know what kind of tool it should be. It can wield strength and kill with one move. The key is that such handy tools are rarely blue.
"Let's go, go to the project meeting." The master urged me after seeing that I finished washing.
The special meeting was filled with smog, and the criminal police officers obviously didn't even have 4 hours of sleep, and all of them had dark circles and swollen eyes.Criminal policemen are like this. They know that smoking is not good, but they often stay up late and can only use cigarettes to refresh and support them.They are all like this, wasting their youth and health to fight crime, protect people, and sometimes suffer all kinds of criticism.
Although it has not been determined whether it was a murder case, it was three lives after all. The investigators conducted investigations according to the murder case throughout the night.Because Lao Xia's family is a single family, everyone in the family was silenced, so after a night of investigation, no valuable clues were found.Witnesses only know that the fire started at 5 o'clock in the afternoon.The investigation of the contradictions and love and hatred of Lao Xia's family also encountered great resistance.The villagers all reported that Lao Xia was a loyal person, and his children were working outside, and no obvious contradictions were found.Therefore, the investigation is currently at an impasse.
When the master said that the autopsy had confirmed that it was a murder case, the investigators were not too surprised, obviously they were all mentally prepared.
"The three deceased were all hit on the head with blunt objects. Lao Xia was hit to the head to death, and the child was burned to death after being stunned by the blow to the head. The combustion aid was gasoline." I got a call from the physical and chemical laboratory, and through inspection, it was determined that the murderer carried gasoline for combustion. "So, the murderer should be someone who can easily obtain gasoline."
This analysis obviously did not arouse the interest of the task force, and the director of the county bureau said, "Is there any other guiding ideology?"
Master shook his head.I am very surprised why Master did not announce our important discovery to the public.
The director's eyes were full of disappointment. It seemed that he originally had great expectations for the criminal investigation experts from the provincial department: "Then...then what should we do next?" He still hoped that Master could give the task force some guidance.
"Next step, let your soldiers rest more." Master said with a smile, "Let everyone rest, look at each one tired, the body is your own, you must put people first."
Even I was very surprised that Master, a workaholic, could say such things.The master went on to say: "Take a break, we will meet again in the afternoon, I haven't made up my mind yet, I'm going to see the scene."
Still watching the scene?I picked up my teacup and took a sip of tea. At the moment, I'm sleepy and I just miss my pillow.
The special case meeting was over, and the investigators all went back to sleep.I reluctantly came to the scene with Master.The scene was still surrounded by a cordon. In case of emergency, the county bureau also sent police to watch outside the cordon.Looking at the policemen on duty who were shivering from the cold, we felt very uncomfortable. We thought that we must solve the case as soon as possible, give the common people an explanation, and save the policemen from suffering a little.
"Look outside. I'll go in and see where the fire started." The master rubbed his red eyes, turned around and said to the trace inspector beside him, "Prepare a sieve for me."
I understood what Master meant for me to look for the blue blunt weapon, and he was going to clean up the ashes at the fire site to see if there were any further discoveries.
According to Master's arrangement, I searched around the scene by myself, only thinking about the blue blunt weapon.After walking for an hour, suddenly, my eyes were stung by a piece of reflection in the grass in the distance. Under the sunlight, the reflection surface shone with blue light.My heart immediately reached my throat, and I ran frantically towards the blue light, putting on gauze gloves while running.
When I ran to the reflective place panting, I suddenly had a feeling of enlightenment: it turned out to be a blue pump.
This piece of grass is about two kilometers away from the scene, and next to it is a small road that villagers usually use to pull scooters. The road is relatively narrow, and cars must not be able to drive in, but bicycles and motorcycles must be no problem.The inflator looks like 80% new, not to the point of being scrapped.In such a special place, I was secretly happy to find such a pump. The possibility of it being the murder weapon is already very high.
I carefully picked up the pump and looked. This pump is thicker than our common models. It is usually used to pump up motorcycles. Its appearance has been wet with dew, and the base is painted with blue paint. The paint has cracked and peeled off, revealing a dark gray undertone.Several reddish-yellow deposits can be clearly seen around the base, and I know it must be bloodstains.
Although I came here with the mental preparation of finding a murder weapon from the beginning, I didn't expect it to be such a big pump.The size of the physical evidence bag I carried with me was obviously not enough, so I had to use two smaller physical evidence bags to cover the two ends of the pump respectively to protect the original traces on it.Because one end is the focus point, it can be determined whether this is really the murder weapon; the other end is the grip point, and evidence to identify the murderer may be found.I just took the pump and ran all the way to the scene, full of joy in my heart: I really found the murder weapon!
As soon as I ran outside the scene, I called out to Master loudly.After a while, Master came out wearing a hood and a mask, smiling all over his face: "Let me guess, you found the murder weapon!"
I nodded vigorously, my face full of excitement.
The master mysteriously raised his gloved right hand and said, "Master and student are united, and their strength cuts through gold. Look, I also discovered it."
Master held a few plastic pieces in his palm, which seemed to have been burned incompletely.
"What's this?" I approached and carefully looked at these unremarkable pieces of plastic, "Master's discovery is not as good as mine, haha."
Master looked at my triumphant look and said, "Don't be too conceited. Take a closer look at these pieces of plastic. I sifted them out from the ashes of the fire." It turned out that Master really spent almost a whole morning , I slowly sifted through the ashes in the center of the scene, and found these pieces of plastic that pleased Master.
These are a few pieces of hard red plastic. I looked over and over for a long time, but didn't find any particularly useful clues. I raised my head and looked at Master.Master was smiling and looking at me: "What? Didn't you discover the mystery?" I looked down again and shook my head blankly.
"Haha, didn't you play jigsaw puzzles when you were young?" Master said.
I am still very confused, even if I can put these pieces together, what can it explain?Although I thought so in my heart, I refused to admit defeat: "I am a master of jigsaw puzzles."
After a while, I put together the burnt pieces of plastic and placed them loosely on the ground.At this time, Master handed me a magnifying glass, and I took it to carefully observe the plastic fragments on the ground, and found a few raised Chinese characters on it, but most of them had been burnt and it was difficult to identify them.I looked up at Master and said, "I don't think there are any good clues?"
The master squatted down, and with a magnifying glass, looked at the joints of some of the fragments, and said, "I may not be able to recognize other characters, but these two characters should be recognizable."
I lowered my head and carefully observed the position in the center of Master's magnifying glass, and sure enough, there were two small characters that were faintly discernible: Pen industry.
"Well, it's a so-and-so pot industry." I scratched my head and said, "I've thought about it a long time ago, since it was the source of the fire, the biggest possibility is the gasoline container, isn't this a good discovery? "
"I also know that it is the ashes of the gasoline container." Master smiled mysteriously, "But have you ever seen someone burn a corpse with a basin of gasoline?"
It turns out that what Master discovered was this, which is an abnormal tool for holding combustion accelerant.I was lost in thought: what can this explain?
Master knew that I still had no idea, pointed to the pump I was holding, and reminded me: "Do you have any thoughts about the murder weapon you found?"
Master's words pulled me back from my contemplation, and I said, "Oh, that's what I thought. This is different from ordinary pumps, it should be the one for motorcycles. And I found that the place where the pump is located is a There is a small road next to the mountain road, and it is unlikely to pass by by bicycle, only on foot or by motorcycle."
"Yes, very good. Could it be that the murderer carried a basin of gasoline on foot to burn the body?" Master said in a teasing tone.
"Could it be gasoline from the dead man's house?" I asked.
"I've also thought about this possibility. I checked and found that the deceased's house did not have any tools that could use gasoline, so there is no need to keep gasoline on hand."
"I see. You mean that the murderer came to the scene on a motorcycle."
"Yes, that's one, and the second is that this case should be a murder of passion." Master said, "Think about it, if it's a premeditated murder, you can use a barrel to bring gasoline, which is easy to carry and pour. The case is that the gasoline was put in a basin, so the most likely possibility is that after the murder, the murderer took local materials and took a basin, used the basin to catch the gasoline in the motorcycle, and then cremated the body."
I nodded, thinking that Master's analysis made sense.Master went on to say: "Although the child's head injury could cause a coma, it did not kill him. This further proves that the murderer committed the murder hastily and burned the body."
I turned around and thought about it, and suddenly I didn't quite understand what Master meant: "Let's go around in a big circle, and if we dare to analyze a passionate murder?"
Master smiled and said, "Yes. But I think it's very important. What does it mean to kill someone passionately in the deceased's home?"
I suddenly realized: "Acquaintances committed crimes!"
Master nodded and said, "That's right. That's what I want to say. Passionate murder is not necessarily committed by acquaintances, but passionate murder in the deceased's home is usually committed by acquaintances."
"However, judging that it is an acquaintance who committed the crime based on just one pot, I always feel that the basis is not very sufficient." Although forensic work often requires reasoning, sometimes we joke that our job is "I guess, I guess, I guess, guess", but we Every reasoning has a sufficient basis. If there is no basis for guessing, the failure rate will of course be high.I still have concerns about Master's inference.
"Of course it's impossible to base it on this alone." Master said as he beckoned me to go to the scene. "I have two other bases."
Walking to the kitchen at the scene, the master pointed to the stove and said, "There is a pot of noodles in the pot, and there are 4 bowls on the table. This is an abnormal phenomenon. There are only 3 people in the family, and it is reasonable to say that 3 bowls are enough.因此多出的这个碗肯定是用来招待熟人的。”
“如果仅仅是认识呢？关系不熟的人，或者路过的人，不可以吗？”我问。
“调查情况很清楚，老夏是一个非常好客的人，如果不熟悉，晚餐不会这么简单。所以我认为，凶手是经常来老夏家吃饭的人。”师父说。
我点点头表示认可，问道：“那第二个依据呢？”
师父接着说：“另外，你还记不记得，3具尸体的身上都没有抵抗伤。尤其是小孩的损伤，是被人从面前一击致晕的，如果不是熟人，这么大的小孩应该会知道遮挡、抵抗。正因为是熟人，所以小孩对他拎着打气筒走进卧室并没有多少防范。”
下午的专案会，小小的会议室内挤满了人，刑警们都已经养足了精神，眼神中都充满了期待。在侦查工作陷入僵局的时候，专案组对刑事技术工作，尤其是法医工作更加充满期待。
“通过一个上午的现场勘查，结合昨天的尸体检验，我们有了新的发现。”师父开门见山。话音刚落，整个专案组都精神振奋。
“我们目前有充分的依据推断此案是一起激情杀人案件，而且是熟人作案。”师父接着说，“凶手应该经常在死者家中逗留，并且有驾驶摩托车的习惯。”在侦查员们神采奕奕的目光中，师父简短地介绍了我们做出如此推断的依据，说得全场纷纷点头。
“侦查范围很小了，我们很有信心。”局长说道，“不过，我们怎么甄别犯罪嫌疑人呢？”
“这次小秦的表现很出色。”师父从桌下拿出我找到的凶器，“我们现在有充分的证据证明这个打气筒就是作案凶器，而且我们在打气筒上找到了可疑的指纹。”
专案会场开始有些嘈杂，大家兴奋地交头接耳。
“那您看，作案动机是什么呢？”局长依旧不依不饶，希望能够尽可能缩小侦查范围。
“既然是激情杀人，动机就不好说了。”师父皱了皱眉头，“但是，凭感觉，里面可能有财物纠纷。”
“哦？有依据吗？”局长顿时来了兴趣。
“有。”师父说，“我在筛现场灰烬的时候，除了发现盆的碎片，也发现了很多不同季节衣物的碎片。”
师父打开现场概貌的幻灯片，说：“大家可以看到，卧室现场虽然房屋基本塌了，但是屋内的衣柜并没有塌。虽然衣柜也被烧毁大部分，里面的衣物也基本烧尽，但是衣物碎片不应该散落得整个现场都是。那么，只有两种可能，一是凶手用衣物当助燃物，二是凶手翻动了现场寻找财物。”
师父喝了口茶，接着说，“既然凶手费了那么大劲儿去摩托车内取油，我觉得就没有必要再搬动衣物做助燃物了，因为现场有很多木头家具和被褥，何必再花时间搬衣服呢？如果是为了在现场寻找财物，那就有可能把衣柜中的衣服弄得满现场都是了。”
局长点点头，问：“既然您说是激情杀人，怎么又会是抢劫杀人呢？”
师父说：“我这里说的激情杀人，是指临时起意的杀人。如果在交谈中，凶手得知老夏有钱，临时动了杀机，也是可能的嘛。”
“我知道该怎么做了，交给我吧。”局长信心满满，转头对摩拳擦掌的侦查员们说，“不用多说了吧，行动吧！”
县局局长、师父和我留在了专案指挥部。师父和局长轻松聊着家常，等待侦查员们的消息。我实在太困了，斜靠在椅子上，不知不觉就睡着了。
不知道睡了多久，一阵急促的电话铃声响了起来。我揉了揉僵硬的脖子，坐直了身体，看见师父也趴在桌上睡着了。局长拿起电话，问：“怎么样？”
听不清电话的那头说些什么，只看到局长的表情充满喜悦。不一会儿，局长挂断了电话，说：“有了你们的推断，我们省大事儿了。”
师父问：“有线索吗？”
局长说：“不是线索的问题，案子破了。”我们顿时兴奋起来，局长接着说，“经过调查，老夏确实是在案发前两天去银行取出了他的全部积蓄3万多块钱。这些钱是准备给他儿子的。他儿子在外做些小生意，有几万块钱的资金缺口，就找老夏借，准备元旦回来拿的。老夏前两天去镇里买东西，顺便取出了钱，藏在家里的衣柜里。”
师父问：“人抓到了吗？”
局长说：“是的。你分析完了以后，目标就基本锁定了，是老夏的亲侄子。这个人天天游手好闲，不务正业，经常去老夏家蹭吃蹭喝。你们说是经常去老夏家吃饭平时还骑摩托车的人作案，我们第一个就想到了他。幸好有这个打气筒以及打气筒上的指纹，让这起案件证据确凿。真的谢谢你们！”
师父继续问道：“过程交代了吗？”每破一个案件，师父都会详细地询问作案过程，然后和我们推断的过程相比对，这样不断地总结，就会不断地提高。
“基本交代了。是老夏无意中说漏了嘴，说自己取了3万块钱，然后那小子就动了杀机。用打气筒打头，再从摩托车内取油焚尸。”又破一起命案，局长很是兴奋。
“都是钱惹的祸。”师父感慨道，“防人之心不可无。亲侄子也会下手灭门啊！”
