Chapter 2, This is not an accident
The deceased did not die in a car accident
The key point is still a secondary permission, what does this actually mean
Xu Dayuan took a deep breath, fixating his gaze on Zhou Ning's eyes. The words just spoken had given Xu Dayuan a slightly different understanding of this newcomer, the novice forensic doctor before him
Xu Dayuan had already removed his mask and walked closer, his expression somewhat serious, seemingly a bit disappointed with Zhou Ning's performance
Forensic scene investigation was a course he studied in his junior and senior years. Although his grades were not particularly good, does it make any difference?
1. Physiological Reactions: Following the application of violent forces to the body, a series of physiological reactions may occur both at the site of injury and systemically. These reactions can be observed through the naked eye, light microscopy, or other laboratory examination methods. Observable changes include hemorrhage, tissue contraction, swelling, scab formation, wound infection, and foreign body movement; histological changes include: accumulation of red blood cells in the subcapsular lymphatic sinuses of local lymph nodes, thrombosis, embolism, inflammatory responses, and wound healing.
What are you all standing there for? Get a ladder and a chainsaw for Dr. Zhou, hurry up and get moving. The rest of you continue searching for brake marks, bloodstains, and debris from the crash at the intersection. Hurry up the traffic police, why hasn't the surveillance footage been retrieved yet?
This action caused him to lose his balance, his hand slipped forward and instinctively pressed against the deceased's leg, causing the body to sway to the left. With this movement, the two corners of the shirt flipped towards the ground, revealing a puncture mark in the shape of a dot beneath the right side of the rib cage, which caught Zhou Ning's attention
The distinction between ante-mortem injuries and post-mortem injuries refers to the differentiation between injuries sustained before death and those occurring after death during the examination of the corpse
At this moment, Zhou Ning's feelings are difficult to express. Although he is unaware of the details of the incident, he understands from a prompt in the system that this case appears to be an accident, yet there must be underlying circumstances.
... ...
His thoughts were instantly pulled back as he was poked twice on the arm
Zhou Ning raised the camera, capturing photographs of the deceased from various angles to document the state of the body, the sound of the shutter clicking continuously.
In an instant, a vast amount of knowledge flooded before Zhou Ning, as if it were trying to force its way into his memory, bringing with it a suffocating sensation as if it were about to burst; he gripped the camera tightly.
Buddy, be careful, what happened? Are you feeling faint from blood?
Both hands hang down, but the fingers are not painted with nail polish, and the nails are trimmed very neatly
Before he could respond, Zhou Ning had already been pulled down by Zhao Xinli, directly squatting beside the inspection box
Such a small dot, yet there are two streaks of blood flowing like columns, and the hem of the skirt is also stained red with blood
The forensic office in the county consists of only two people. You need not imagine the kind of scene depicted in television dramas where various forensic personnel have distinct roles, such as marking traces, taking photographs, labeling evidence, and finally, the forensic doctor examining the body.
The system task has been completed, and rewards are being extracted
Zhou Ning evaded Zhao Xinli's claws
The entire corpse was almost hanging upside down at a seventy-degree angle from the tree branch
One of the tasks of forensic pathology is to identify these vital reactions in order to infer the time elapsed from the application of violence to death. Vital reactions and post-mortem reactions are two distinct concepts
The deceased's long hair hung down towards the ground, with the head tilted to the right side. The eyelids were adorned with shimmering gold eyeshadow, and exaggerated large golden hoops were worn on the ears. The exposed left cheek showed signs of swelling, with glass shards embedded in the cheek, as well as bruising around the eye area.
The ladder is made of aluminum alloy, and it creaks as one steps on it. After ascending four steps, Zhou Ning's body swayed, and his lower back was pressed against Zhao Xinli's large hand
The primary basis is whether the injury itself exhibits signs of life response. In the original scene of pre-mortem injuries, splattered bloodstains are visible, and there are large pools of blood around the corpse, with clots present in the blood pools. Such characteristics are absent in post-mortem injuries or when the scene is fabricated after the body has been moved
System prompt
Step up again, hurry and do as instructed, do not say that keeping your legs pressed against the ladder is a way to stabilize your body
Buddy, take it slow, straddle the ladder, cross your left and right legs, squeeze tightly, and lift your hips.
Forensic scene study is the application of knowledge from forensic medicine, forensic clinical science, criminal psychology, biology, and physics to investigate cases involving death and injury. It involves reconstructing and depicting the criminal process at the crime scene, providing a basis for determining investigation directions and formulating investigative measures
Xu Da, I have finished taking the photos. You can find someone to saw off the branches, use a forklift to support the flatbed, and put the body in a bag
After taking the photo, Zhou Ning leaned against the tree trunk, wanting to stretch forward.
Zhou Ning shook his head and continued to flip through the photos taken of the lower edge of the deceased's right rib.
The ladder is placed under the tree, and Zhou Ning nods to Zhao Xinli.
Congratulations to the binder for obtaining Level 2 access to the Forensic Scene Study System. It will be fully loaded in two minutes
Just as he was lost in thought, his ankle and belt were already grabbed by Zhao Xinli, who seemed to be worried that Zhou Ning would fall as he swayed
Are you saying that this is a hit-and-run case
Zhao Xinli made an OK gesture; after all, wearing a mask, this action is more direct than a toothy smile.
A series of commands, imbued with a strong sense of urgency, prompted some to make phone calls to borrow a chainsaw, while others dispersed in different directions
Rest assured, with your weight of around 100 to 110 pounds, I can easily lift you without any issue, ensuring you won't fall. Go ahead!
The red checkered skirt flipped to the side of the body, with very little fabric in the shorts, barely covering the palm-sized private areas. The upper body was dressed in a tight-fitting white shirt, featuring a pink Kitty cat printed on the front.
At this moment, the rain had long ceased, and the clothing on the corpse was not completely soaked, with visible water stains. Looking up at the dense leaves, it seemed that this location still provided good shelter from the rain. However, from where did the person come to be thrown here
A burly criminal police officer ran back carrying a long ladder. Zhou Ning recognized him; his name was Zhao Xinli
Zhou Ning knew that Xu Da was anxious, and he made an effort to calm himself down
Zhou Ning wants to strangle him, what will others think of this
Zhou Ning gritted his teeth, placed the inspection box on the ground, slung the camera under his arm, and climbed up the ladder.
After a pause of more than ten seconds, although I had not fully absorbed this knowledge, all the information I had just discovered became clear and organized.
Are you saying that this is not an accident, but a homicide
PS:
Zhou Ning was completely bewildered, what... what kind of reward is this
Reflecting on the task assigned by the system, Zhou Ning felt an overwhelming sense of powerlessness, and his mind began to wander.
However, this subconscious action caused the transparent display screen to reappear, and various contents learned from forensic science continuously flashed in my mind
Can you see anything? Tell me the truth.
"Dr. Zhou, why are you in a daze? Hurry up and take a look. Even if you don't understand, just say a few words. Quickly take some photos; we will transport the body away."
Xu Da, I just want to take a look at the height and the condition of the body. We cannot recklessly go up and move it, right? By the way, is there a ladder here? I didn't expect the body to be at such a height, and I wasn't prepared. Additionally, we need a chainsaw, the kind that can cut through branches.
Xu Dayuan glanced around, slightly tilted his head, and asked in a lowered voice:
In this small place, everything must be handled personally; this matter has been conveyed to him by Forensic Doctor Liu
Zhou Ning tried to incorporate several technical terms to appear more professional
Zhou Ning was taken aback; the deceased had a fracture in the left leg and bruising on the left side of the face, yet there were stab wounds on the right side
The female corpse is hanging down with her head on the opposite side of the tree trunk, her right leg draped over the trunk, while her left leg is broken at the calf and pressed beneath the right leg, with the broken part wedged in the gap of a slanted branch.
A newly arrived forensic expert is able to analyze the situation with such composure, which is already unexpected, especially since he has prepared to directly remove the body.
The left calf, cheek, and head of the deceased show signs of impact; however, there is a stab wound located at the posterior edge of the right rib cage.
The photos just taken are also being displayed one by one on the screen
Upon hearing Zhou Ning's request, Xu Da did not get angry
The general teachers in the school, along with the amputated limbs observed during the internship, are essentially just for distant observation. At most, you might get to touch them, and there are a lot of people accompanying you, surrounded by the smell of formaldehyde, which provides a strong sense of security. You just need to listen to the teacher and nod in agreement; it is not nearly as visually shocking.
The foundation of forensic scene reconstruction is the on-site investigation work. Crime scenes and injury scenes serve as a repository of information for obtaining criminal intelligence, are important locations for identifying the nature of cases, and are the starting point for conducting investigative work
I apologize, I have a bit of acrophobia. Xu Da, look here, the deceased has an open fracture of the tibia and fibula on the right calf, and there are abrasions here. It can be determined that she was struck and then fell onto the tree. This is the first scene.
As soon as this thought emerged, a transparent screen appeared before Zhou Ning, displaying the corpse of the deceased as if it had been scanned.
How is it?
Is it possible that ... ...
Brother Zhao, please hold the ladder for me, I want to go up and take a photo
The individual who bound the victim came into contact with the corpse, and the external autopsy revealed suspicious points regarding the cause of death
At the same time, his hand rested on Zhou Ning's shoulder, and his voice lowered further.
The surface information he discovered has also been organized on one side
Due to the special position of the body at this moment, I am unable to assess the depth of the stab wounds. However, the wounds have not scabbed over, there are vertical bloodstains on the ground, and there are signs of life response [1]. This indicates that the injuries were sustained while the individual was alive [2], and they were inflicted shortly before the car accident.
He averted his gaze and once again urged those responsible for vigilance around him to delete any photos taken by onlookers before allowing them to leave
Zhou Ning pushed up his glasses, the mask obscuring the tension on his face, giving him an appearance of calmness. Only he knew how anxious he truly was at that moment
The latter refers to the early stage of biological death, during which certain tissues and organs that are highly tolerant to ischemia and hypoxia, such as the skin and muscles, still exhibit life functions and can respond to external stimuli in a manner similar to that before death
He stood at a position slightly higher than the corpse, and at this angle, he was able to see the full view of the body.
It seems that such actions have instilled confidence in Xu Dayuan
The grip of my hand relaxed as I found the photograph of the deceased's leg, pointing and saying
