Chapter 2 This is not an accident
Thinking about the task given by the system, Zhou Ning felt powerless, and people were a little distracted.
The arm was poked twice, instantly pulling his thoughts back.
"Forensic doctor Xiao Zhou, what are you stunned about? Hurry up and take a look, it doesn't matter if you don't understand, just say a few words, hurry up and take pictures, and we'll transport the body away. ”
Zhou Ning knew that Xu Da was in a hurry, and he tried to calm himself down.
"Xu Da, I just look at the height, and the state of the corpse, you can't rush up and flip it, right, by the way, there is a ladder here? I didn't expect the body to be in a high place, I didn't prepare it, and I needed a chainsaw, the kind that could cut the branches. ”
Hearing Zhou Ning's request, Xu Da was not angry.
A new forensic doctor can analyze it calmly, which is already unexpected, after all, he is ready to directly take away the body.
"What are you doing in a daze, find a ladder and a chainsaw for Xiao Zhou's forensic doctor, hurry up and move, you continue to search for brake marks, bloodstains, and crash debris at the intersection, urging the traffic police team, why hasn't the monitoring been called out yet?"
A series of commands, the sense of oppression is extremely strong, some people go to call to borrow chainsaws, and some people scatter.
A five-year-old and three-thick criminal policeman ran back with a long ladder, Zhou Ning knew him, this person's name was Zhao Xinli.
The ladder was placed under the tree, and Zhou Ning nodded at Zhao Xinli.
"Brother Zhao, help me hold the ladder, I want to go up and take pictures."
There are only two people in the county's forensic office, you don't have to think about the kind of trace examiners you see in the TV series to go up to their own division of labor, and it is the traces that plant flags, and the photos and labels to collect evidence, and finally the forensic doctors observe the corpses.
In this small place, you have to come by yourself, and Forensic Doctor Liu has explained this to him.
Zhao Xinli made an OK gesture, after all, he was wearing a mask, and this action was the most intuitive than smiling.
"Don't worry, just your hundred and ten pounds, I'll give you a lift, I guarantee that I won't fall you, let's go!"
Zhou Ning gritted his teeth, put the survey box on the ground, straddled the camera diagonally under his armpit, and grabbed the ladder and climbed up.
The ladder is made of aluminum alloy, and when he stepped on it, it made a creaking sound, and when he went up the four steps, Zhou Ning's body shook, and his back buttocks were held by Zhao Xinli's big hand.
"Man, slow down, cross your legs over the ladder, cross your left and right feet, clamp hard, and lift your buttocks."
Zhou Ning dodged Zhao Xinli's claws.
Take another step up, hurry up and do it, don't say that holding the ladder between your legs like this can be regarded as stabilizing your body.
He stood slightly higher than the corpse, and at this angle, he could see the whole picture of the corpse.
The general teachers in the school, as well as the stumps that have been seen in the internship, to put it bluntly, are all from a distance, let you touch the sky, and a lot of people accompany you, smell the smell of formalin, full of security, listen to the teacher, you are responsible for nodding your head, there is no visual impact at all.
The head of the female corpse hung down to the other side of the trunk, her right leg hung from the trunk, the left leg had been broken off in the calf part, pressed under the right leg, and the broken part was inserted in the gap between the branches diagonally below.
The whole corpse, almost seventy degrees angled, hung upside down on the branch.
The red plaid skirt flipped over to the side, the shorts were made of very little fabric to cover the private parts of the palm, and the upper body wore a tight white shirt with a pink Kitty cat printed on the chest.
The deceased's long hair hung down to the ground, his head was tilted to the right, his eyelids were covered with shiny gold powder eyeshadow, his ears were wearing exaggerated gold rings, and the left side of his cheek was swollen, with glass ballast tied to his cheeks, and bruises on his eye sockets.
His hands hung down, but his fingers were not painted and his nails were neatly cut.
At this time, the rain had long stopped, the clothes on the corpse were not completely soaked, and the marks of water stains could be seen.
Zhou Ning raised the camera and took pictures of all positions of the deceased, fixing the state of the deceased, and the shutter sound was constantly clicking.
It seems that such actions have given Xu Dayuan confidence.
He staggered his gaze and once again urged the people in charge of guarding around him, and all the onlookers who took pictures were deleted and let people leave.
After taking the photo, Zhou Ning held on to the trunk of the tree and wanted to lean forward.
This action made his center of gravity unstable, his hand slid forward, and subconsciously pressed on the deceased's leg, and the corpse swung to the left, with this action, the two corners of the shirt flipped in the direction of the ground, and the lower edge of the rib on the right side, a dot of stabbing marks, fell into Zhou Ning's eyes.
It was just such a small dot, but there were two columnar traces of blood, and the edges of the skirt were also stained red with blood.
Zhou Ning was shocked, the deceased's left leg was fractured, and there was a bruise on the left side of his face, why was there a stab wound on the right side?
Don't......
The deceased was not killed in a car accident?
As soon as this idea came to mind, the transparent screen in front of Zhou Ning's eyes also appeared at the same time, and the body of the deceased seemed to be scanned and displayed on the screen.
System Prompt:
The bound person touched the corpse, and the autopsy on the body surface found a suspicious cause of death.
The system task has been completed and the reward is being drawn.
"Di, congratulations to the binder, I have obtained the second-level permission of the knowledge of the forensic field learning system, and it will be loaded in two minutes."
Zhou Ning's whole person was stunned, this ...... What kind of reward?
Forensic field study is a course he took in his junior and senior years, although his grades are not good, but is there any difference?
The key is still a second-level permission, what does this mean?
Just when he was distracted, his feet, neck and belt had been grabbed by Zhao Xinli, and it was estimated that he was shaking for fear that Zhou Ning would fall down.
"Dude, be careful, what's wrong? Faint blood? ”
Zhou Ning wanted to strangle him, what do others think of this?
Without waiting for him to answer, Zhou Ning had already been carried down by Zhao Xinli and squatted directly next to the survey box.
Xu Dayuan had already ripped off his mask and walked closer, his face was a little serious, and he seemed to be a little disappointed in Zhou Ning's performance.
"What's going on?"
"Xu Da, after I finish taking pictures, I can find someone to sawn off the branches, use a forklift to hold the flat plate, and bag the body."
Xu Dayuan looked around, tilted his head slightly, lowered his voice and asked:
"Do you see something? Tell me the truth. ”
Zhou Ning pushed his glasses, and the mask blocked the nervous expression on his face, making people look quite indifferent, only he knew how nervous he was at the moment.
However, with this subconscious action, the transparent display screen reappeared, and various contents of forensic on-site learning kept flashing in my mind.
Forensic scene science is to use the knowledge of forensic science, forensic clinical science, criminal psychology, biology and physics and other natural sciences to study cases involving life and injury, and to reconstruct and portray the criminal process at the scene of the crime, so as to provide a basis for determining the direction of investigation and formulating investigation measures.
The foundation of forensic scene reconstruction is the on-site investigation work, and the scene of fatality and injury is the information base for obtaining criminal intelligence, an important place for screening the nature of the case, and the starting point for carrying out the investigation work......
In an instant, a huge amount of knowledge filled Zhou Ning's eyes, as if he was about to squeeze into his memory, and a feeling of suffocation came from him, and he pinched the camera tightly.
After a delay of more than ten seconds, although this knowledge was not digested, all the information just discovered became clear.
On the display screen, the photos just taken are also displayed one by one.
The body surface information he found was also sorted out on one side.
Zhou Ning's mood at this time, I don't know how to express it, although I don't know the process of the case, but according to the prompt in the system, Zhou Ning knows that this case seems to be a car accident, but there must be hidden secrets.
The strength in his hand loosened, and he found a photo of the deceased's leg, pointed and said:
"I'm sorry, I'm a little afraid of heights, Xu Da, look, the deceased's right calf, tibia and fibula open fracture, and the abrasions here, it can be determined that she fell on the tree after being knocked into the air, this is the first scene."
"You mean, it's a car accident and run case?"
Zhou Ning shook his head and continued to dig out a photo of the lower edge of the deceased's right rib.
"There are impact marks on the left side of the deceased's calf, cheek and head, but there is a stab wound here on the right side of the lower edge of the ribs, posteriorly.
Because of the special position of the body at the moment, I could not check the depth of the stab wound, but the wound was not scabbed, there were columnar blood stains on the vertical ground, and there was a life reaction [1], which was a pre-mortem injury [2], and it was caused in a short period of time before the car accident. ”
Zhou Ning tried his best to drag a few professional terms to make himself look professional.
Xu Dayuan took a breath and stared at Zhou Ning's eyes, these words just now made Xu Dayuan have a different understanding of the new forensic doctor in front of him.
At the same time, his hand was on Zhou Ning's shoulder, and his voice was further depressed.
"You're saying it's not an accident, it's a homicide?"

PS:
[1] Life reactions: After the body is subjected to violent effects, a series of life reactions can occur in the injured area and the whole body, and these life reactions can be glimpsed through the naked eye, light microscope or other laboratory examination methods, among which the macroscopic changes include bleeding, tissue contraction, swelling, crust formation, wound infection, foreign body movement, etc.; Histologic changes include: subcapsular lymph node subcapsal lymph sinus red blood cell aggregation, thrombosis, embolism, inflammatory response, wound healing, etc.
One of the tasks of forensic pathology is to look for these life responses in order to extrapolate the time elapsed from the effects of violence to death. Life reaction and supernatural reaction are two different concepts.
The latter refers to the fact that in the early stage of biological death, some tissues and organs, such as skin and muscles, that are strongly tolerant to ischemia and hypoxia, still have vital functions, and can react to external stimuli similar to those before death.
[2] Antemural injury: The distinction between anterior and postmortem injuries refers to the distinction between antemortem and postmortem injuries at the time of autopsy.
It depends mainly on whether the injury itself has a life reaction. At the original site of the pre-mortem injury, splattery of blood was visible, and there was a large area of blood around the corpse, and clots were visible in the blood pool. There are no such characteristics when posthumously injured or when the body is removed from the scene.
