novice forensic medicine

Chapter 2 This is not an accident

Thinking of the task given by the system, Zhou Ning felt powerless and a little distracted.

His arm was poked twice, pulling him back from his thoughts in an instant.

"Forensic doctor Xiao Zhou, why are you in a daze? Hurry up and have a look. It doesn't matter if you don't understand, just say a few words, hurry up and take pictures, and we will transport the body away."

Zhou Ning knew that Xu was in a hurry, and he tried to calm himself down.

"Xu Da, I just want to check the height and the state of the corpse. You can't rush up and flip it over, right? Is there a ladder here? I didn't expect the corpse to be at a high place. I didn't prepare for it. I also need a chainsaw to cut off the branches. Kind of."

Hearing Zhou Ning's request, Xu Da was not angry.

It was unexpected for a new forensic doctor to be able to analyze so calmly. After all, he was ready to take away the corpse directly.

"What are you doing in a daze, find a ladder and a chainsaw for Xiao Zhou's forensic doctor, move quickly, you guys continue to search the intersection for brake marks, blood, and debris from the crash, and urge the traffic police team, why is there no monitoring? call out?"

The series of instructions felt extremely oppressive. Some people called to borrow chainsaws, and some scattered.

A criminal policeman who was five-year-old and three-year-old ran back with a long ladder. Zhou Ning knew him, and his name was Zhao Xinli.

The ladder was placed under the tree, and Zhou Ning nodded towards Zhao Xinli.

"Brother Zhao, help me hold the ladder, I'm going up to take pictures."

There are only two people in the forensic room in the county. You don't have to think about the trace inspection personnel you see in the TV series. They go up and divide their work. They put up traces and flags, take pictures and mark evidence, and finally the forensic doctor observes the corpse.

Here is a small place, you have to come by yourself, this matter has been explained to him by Liu Fayi.

Zhao Xinli made an OK gesture. After all, he was wearing a mask. This gesture is the most intuitive compared to grinning.

"Don't worry, it's only about a hundred catties, I'll give you a lift, it's no problem, I guarantee I won't fall you, go on it!"

Zhou Ning gritted his teeth, put the survey box on the ground, put the camera under his arm, and climbed up the ladder.

The ladder was made of aluminum alloy, and it made a creaking sound when it was stepped on. After climbing up to four steps, Zhou Ning swayed, and Zhao Xinli's big hand held his buttocks.

"Slow down, man, step over the ladder with your legs, cross your left and right feet, clamp them hard, and lift your hips."

Zhou Ning avoided Zhao Xinli's claws.

Take another step up, and do it quickly, not to mention holding the ladder between your legs like this, which is considered to stabilize your body.

He was standing slightly higher than the corpse, and from this angle, he could see the whole body of the corpse.

The general teachers in the school, and the stumps that have been seen in the internship, to put it bluntly, are from a distance, let you touch the top of the sky, and a lot of people accompany you, smelling the smell of formalin, safe It is full of emotion. Listening to the teacher, you just need to nod your head. It’s not as big as the visual impact.

The head of the female corpse hangs down to the other side of the tree trunk. The right leg hangs on the tree trunk. The left leg has been broken at the lower leg and is pressed under the right leg. The broken part is inserted into the gap between the branches diagonally below.

The entire body was hanging upside down from a tree branch at an almost seventy-degree angle.

The red plaid short skirt was turned over to the side of the body. The shorts had very little fabric and could only cover the palm-sized private parts. The upper body was wearing 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 turned to the right, his eyelids were covered with shiny gold powder eyeshadow, and his ears were worn with exaggerated gold rings. The exposed left cheek was swollen and covered with glass shards. On the cheeks, there are bruises around the eye sockets.

The hands hang down, but the fingernails are not painted, and the nails are neatly trimmed.

The rain had stopped long ago, and the clothes on the corpse were not completely soaked, and water stains could be seen. Looking up at the thick leaves, it seemed that this position was still sheltered from the rain, but where did the person come from?

Zhou Ning raised the camera and took pictures of the deceased in every position, fixed the state of the deceased, and the shutter clicked continuously.

It seemed that such an action gave Xu Dayuan confidence.

He staggered his gaze, and once again urged the people in charge of security around him to delete all those who took pictures of the onlookers before letting them leave.

After taking the photo, Zhou Ning supported the tree trunk and wanted to lean forward.

This action made his center of gravity unstable. He slid his hand forward and subconsciously pressed it on the leg of the deceased. On the lower edge of the ribs, a dot of stab wounds fell into Zhou Ning's eyes.

It was just such a small dot, but there were two columnar traces of blood flowing, and the edge of the skirt was also stained red with blood.

Zhou Ning was shocked. The deceased had a broken left leg and bruises on the left face. Why was there a stab wound on the right side?
Is it
The deceased did not die in a car accident?

As soon as this idea came up, the transparent screen in front of Zhou Ning also appeared at the same time, and the dead body seemed to be scanned and displayed on the screen.

system hint:

The bound person touched the corpse, and the cause of death was found to be suspicious from the autopsy on the body surface.

The system task is completed and rewards are being drawn.

"Hey, congratulations to the binding person, who has obtained the second-level authority of the forensic field study system knowledge, and the loading will be completed in two minutes."

Zhou Ning was dumbfounded, what kind of reward is this?
Forensic field study was a course he took in his junior and senior years. Although his grades were not very good, is there any difference?

The key is still a secondary authority, what does this mean?
Just when he was distracted, Zhao Xinli had already grabbed his ankle and belt. It is estimated that Zhou Ning was afraid of falling down when he was shaking.

"Be careful, buddy, what's the matter? Are you dizzy?"

Zhou Ning wanted to strangle him, so what do others think?
Before he could answer, Zhou Ning had already been picked up by Zhao Xinli and squatted next to the investigation box.

Xu Dayuan had already pulled off his mask, and walked up to him with a serious face, as if he was a little disappointed with Zhou Ning's performance.

"How is it?"

"Xu Da, I finished taking pictures, I can find someone to saw off the branches, use a forklift to hold the tablet, and bag the body."

Xu Dayuan looked around, tilted his head slightly, and asked in a low voice:

"See something? Tell me the truth."

Zhou Ning pushed his glasses, and the mask blocked the nervous expression on his face, making people look calm, only he knew how nervous he was at the moment.

However, with this subconscious action, the transparent display screen reappeared, and various contents learned on the spot of forensic medicine kept flashing in his mind.

Forensic on-the-spot study is the use of natural science knowledge such as forensic medicine, forensic clinical science, criminal psychology, biology and physics to study cases involving life and injury, reconstruct and describe the criminal process at the crime scene, and determine the direction of investigation. , Formulate investigative measures to provide a basis.

The basis of forensic scene reconstruction is the on-site inspection work. The murder scene and the injury scene are the information base for obtaining criminal information, an important place to identify the nature of the case, and the starting point for the detection work.
In an instant, a huge amount of knowledge flooded in front of Zhou Ning's eyes, as if it was about to be squeezed into his memory, and a burst of suffocation came, and he squeezed the camera tightly.

After a delay of more than ten seconds, although the knowledge had not been digested, all the information just discovered became clearer.

On the display screen, the photos just taken were also displayed one by one.

The body surface information he discovered was also sorted out on one side.

Zhou Ning didn't know how to express his feelings at this moment. Although he didn't know the process of the crime, but according to the prompt in the system, Zhou Ning knew that this case looked like a car accident, but there must be something hidden.

The strength in his hand loosened, and he found the photo of the deceased's leg, pointed at it and said:

"Sorry, I'm a little afraid of heights. Look, Da Xu, the deceased's right calf, open fracture of the tibia and fibula, and the scratches here, can be judged that she fell on the tree after being knocked into the air. This is the first place." on site."

"You mean, this is a getaway case?"

Zhou Ning shook his head, and continued to dig out the photo of the lower edge of the deceased's right rib.

"There were impact marks on the left side of the deceased's calf, cheek and head, but on the right side just behind the lower edge of the ribs, there was a stab wound.

Because the corpse is in a special position at the moment, I can't check the depth of the stab wound, but the wound has no scabs, there are columnar blood stains vertical to the ground, and there is a life reaction [1], this is an injury before death [2], and it was just before the car accident, a short time caused within. "

Zhou Ning tried his best to drag out a few professional terms to make himself look more professional.

Xu Dayuan took a breath, and stared firmly into Zhou Ning's eyes. The words just now made Xu Dayuan have a different understanding of the new manipulator in front of him.

At the same time, with his hands on Zhou Ning's shoulders, his voice was further lowered.

"You mean it wasn't an accident, but a murder?"

PS:
【1】Life reaction: After the body is subjected to violence, a series of life reactions can appear in the injured part and the whole body. These life reactions can be seen through the naked eye, light microscope or other laboratory inspection methods. The changes of the naked eye include bleeding, tissue Shrinkage, swelling, crust formation, wound infection, foreign body movement, etc.; histological changes include: local lymph node subcapsular lymphatic sinus red blood cell aggregation, thrombosis, embolism, inflammatory response, wound healing, etc.

One of the tasks of forensic pathology is to look for these living responses to infer the time elapsed from the violent effect to death.Life response and hyperbiotic response are two different concepts.

The latter refers to that in the early stage of biological death, some tissues and organs that are highly resistant to ischemia and hypoxia, such as skin and muscle, still have vital functions, and can respond similarly to external stimuli as they did before death.

【2】Ante-mortem injury: The identification of ante-mortem injury and post-mortem injury refers to the distinction between ante-mortem injury and post-mortem injury during autopsy.

It is mainly based on whether the injury itself has a life response.In the original scene of the injury before death, spatter-like blood stains can be seen, and there is a large pool of blood around the corpse, and blood clots can be seen in the pool of blood.There are no above-mentioned characteristics when injured after death or when the corpse is faked.
