Chapter 185 Practice is the only criterion for testing truth 1
Wen Jing stepped forward, pushed his glasses up with his index finger, and said, "Professor Lu, the bones are still being salvaged, let me inspect the body first."

Lu Beichen stood still, and said calmly, "Wait a minute."

I don't understand the context.

Lu Beichen kept looking towards Gu Chu with a calm expression.Realizing that Lu Beichen was waiting for Gu Chu, the context felt anxious. He had been in the laboratory for three years, and he knew that Lu Beichen was not a very patient person, so he was afraid that he would turn his anger on Gu Chu.But after waiting for five or six minutes, it became more and more strange that he still didn't see him getting angry.

When Gu Chu came back, his face was almost pale, similar to that of the witness. Seeing that Lu Beichen had been waiting in place, he felt very guilty, and put on a mask after suppressing the overwhelming feeling.

"How is it?" Lu Beichen asked.

Gu Chu nodded vigorously, "No problem."

After Lu Beichen looked at her for a long time, he turned to look at the context, "Gloves."

"Ah?" The context was taken aback for a moment, and he quickly realized, "You want to do an autopsy yourself?"

In the past, if people from the laboratory came to the scene, Lu Beichen would not do it himself under normal circumstances, unless there was a major problem with the corpse, or he would operate the knife after the corpse was transported back to the laboratory.

Lu Beichen didn't say much.

Yu Jing hurriedly handed the gloves to Lu Beichen, and looked at Gu Chu again.Lu Beichen ordered, "Give her a pair of gloves."

The context does the same.

Gu Chu's heart was pounding when he took the glove, no matter whether it is a human or an animal, they all have a natural fear of corpses of their own kind.When they were studying medicine, their instructors trained them to overcome this fear, so they would often come into contact with the corpses used for dissection experiments, but after all, they were not facing death directly, not as bloody as they are now.

After she put on the gloves, Lu Beichen said, "You will be in charge of the scene map later, and I will teach you how to do it. In addition, you have to watch carefully when I am doing the preliminary autopsy, and you must remember the process and judgment. Next time I will let you inspect it yourself."

As soon as Gu Chu heard this, the stone in his heart dropped. Fortunately, it was not for her to touch those corpses.

Jingjing looked at Gu Chu with weird eyes.

"Let's go." Lu Beichen walked ahead.

Gu Chu clenched his fists and followed behind him with all his energy.Wenjing walked quickly, walking side by side with Gu Chu, whispering, "Professor Lu is teaching you? You are lucky."

Gu Chu really wanted to reply him a few words politely, but Naihe felt like throwing up as soon as he opened his mouth, so he restrained himself from speaking.

Lu Beichen tilted his head slightly, and let out a low voice towards the context, "What are you dawdling about?"

The context stepped forward in a hurry.

On-site survey, each functional personnel has their own busy work.

"Protecting the scene, observing the surroundings of the scene, determining the scope and order of the investigation according to the specific conditions of the scene, etc. can all be carried out at the same time as the arrival of the forensic doctor. evidence." Lu Beichen patiently taught Gu Chu some common sense on the scene one by one, "The road we are taking now is the route specially set aside by the on-site investigators, and it is the designated route for special personnel to enter the scene, especially the homicide scene. Routes are extremely important."

Gu Chu nodded.

The closer you get to the body, the stronger the foul smell.

After Luo Chi and the others finished extracting the traces, Lu Beichen took out the tools, squatted down in front of the corpse, and first observed briefly. Gu Chu knew that he was doing a static survey.Jingjing handed her a notebook and a pen, she was taken aback, and asked, "Isn't it possible to input the scene map with a computer?"

The context whispered, "It's what Professor Lu meant."

Gu Chu looked at Lu Beichen.

Lu Beichen was not far away from her, so she could hear clearly when he spoke. He glanced back at her and said, "I need you to draw a picture of the scene yourself, not only the picture of the scene, but also the state, shape, and degree of damage of the corpse. , I need you to mark the important points during the dynamic survey, you have to memorize and draw them one by one."

Gu Chu finally understood her value somewhat.

I dare say that he sees that she has some art skills, well, it's all used in this.

But at the scene of the death, he was the biggest, even Luo Chi had to look at his face, how dare she say no?Although Lu Beichen's request is abnormal, you must know that handwriting and on-site computer records are two different things. Painting needs to be seen clearly at a glance.

God, she felt sick again, thinking that she would draw and draw for a while and don't spit on him, that would be a big embarrassment.

"When we arrived at the scene, the first task was to give the initial death time of the deceased." Lu Beichen moved his hand, and pressed one of the corpses that resembled a leg bone, "Gu Chu, let's talk about it and determine the deceased's time." What are the ways of dying time."

Gu Chu desperately devoted all his energy to the case, and replied, "Generally speaking, the first thing to do is to observe the corpse spots. Pressing down on the corpse spots will fade the color, so it can be preliminarily determined that the death time of the deceased was within twelve hours. , In addition, the body temperature and liver temperature can be measured. Within ten hours of death, the temperature of the body will drop by one degree per hour, and after more than ten hours of death, the temperature of the body will drop by 0.5 degrees per hour. Um... also Judgment can be made based on the gastrointestinal contents of the deceased."

When she was answering Lu Beichen's question like a primary school student, Lu Beichen seemed to turn a deaf ear to it, and was busy with his own affairs, and ordered the context to measure the temperature of the hot spring pool water, and after carefully identifying the contents of the corpse, his eyebrows frowned. locked.

Gu Chu didn't know if he was listening, but he wanted to finish this task first, so he continued, "From the perspective of internal medicine, if a person eats on time, digestion will also have a certain pattern." She was lucky that she was a medical student. Otherwise, she would have to study hard on the knowledge of the living before supplementing the knowledge of the dead. "If you die within 2 hours of eating, the content you eat will be digested to a certain extent. The most obvious feature is that the food will move from the stomach to the duodenum. If you die within 4 hours, chyme can be seen in the stomach. After more than 6 hours, the stomach and duodenum are empty, so the time of death of the deceased can be roughly calculated based on the time of the deceased's last meal."

Lu Beichen didn't speak.

Gu Chu felt that he was busy in vain, and looked up at the context, and the context gave her a thumbs up, expressing his encouragement to her as a beginner.

"The temperature of the hot spring water is as high as more than 90 degrees. This will not be the first scene of the crime. Hot water will not kill people instantly. If the murderer wants to do something here, he must wait until the victim drowns before dismembering the body." As for whether the deceased died of drowning, you can check the water accumulation in the lungs, bronchi and dorsal throat trauma during the autopsy." Lu Beichen spoke in a slow voice, "However, in this high temperature, if you want to Determining the time of death will not be too accurate, because high fever will greatly promote rigor and corruption, so Gu Chu, you have to learn how to choose judging criteria based on the current situation of the scene."

It turned out that he listened to every word.

Gu Chu felt like a primary school student who could only memorize things by rote. He was right. If the high temperature accelerates the decay of the corpse, then the above three methods she proposed would all have errors.

"The corpse is severely swollen. Even if the severed limbs are found, the fingers will wrinkle due to soaking in water, but so far, the tissue of the corpse has not been seriously damaged." Lu Beichen stretched out his hand in the air, "Take a sample and put it on the glass."

Yu Jing hurried forward, but heard Lu Beichen say, "You look for Gu Chu."

Gu Chu immediately stepped forward, took out the carrier glass from the toolbox and handed it to Lu Beichen. He took a look and said patiently, "Two pieces are needed for sampling."

"Oh, I'm sorry." Gu Chu apologized again and again, feeling extremely ashamed, and immediately took another slice and handed it over.

"Remove the finger pad skin of the deceased from the fingerprint ridge, and clamp it with glass carrier. We need to protect the relevant tissues of the deceased in the shortest possible time, because these tissues will be further destroyed. The fastest time to protect is also the fastest. We found information that is beneficial to us within a short period of time." Lu Beichen signaled her to step forward, holding tools, and took the relevant tissues of the deceased very carefully and skilfully.

Gu Chu nodded, and hurriedly marked these key points on the composition album.

It's just that her stomach was still tossing and tossing, she pressed and pressed.

"Corpse spots, body temperature and gastrointestinal contents are the most basic, but they are not a universal standard for measuring the time of death of the deceased. The evaluation of rigor will be affected by many factors, such as the current surrounding temperature, so rigor is determined to be dead. The time spent on the deceased is of little value, not to mention that the body has been disassembled and some bones are still being salvaged. If the temperature of the body is at such a high temperature, it may have reached the same temperature as the surrounding body in less than 12 hours. The temperature is equivalent, so it won't be very useful. Just now, the context has measured the temperature of the pool water. We can only give an approximate time of death based on the current situation, so that Luo Chi and the others can quickly investigate. "Speaking of this, Lu Beichen got up and handed the mention in his hand to the context, and the context immediately put it away.
