Coroner Ke Xue

Lin Xinyi slowly walked to Uchida's body.

Uchida was still lying quietly on the ground. This bullying victim who did not receive enough attention during his lifetime finally received belated attention from the police and society after his death.

"Gloves."

Like a busy attending physician during an operation, Lin Xinyi directly stretched out his hand and asked for tools from the police officers present.

"Here he is." A young police officer hurried forward carrying a forensic investigation box.

Taking a closer look, it was the old acquaintance I met in the morning, Inspector Komatsu, who was part-time coroner.

He was the coroner when Lin Xinyi was away. Now seeing Lin Xinyi's presence, Inspector Komatsu automatically reduced himself to the status of suitcase assistant.

He opened the tool box and respectfully handed Lin Xinyi a pair of gloves.

“Want two pairs”

Lin Xinyi looked helplessly at this "comrade" who was not good at cooking.

"Uh" Inspector Xiao Song's face turned red and he quickly gave Lin Xin a pair of gloves.

Lin Xinyi quickly put on his gloves and looked at Xiaosong Inspector meaningfully and said:

"Let me help you with the autopsy examination this time."

"Write down what I said in order."

"Okay!" Inspector Xiaosong readily agreed. Anyway, he didn't know how to check.

At this time, Lin Xinyi finally started to act.

He was not in a hurry to tell the truth about the case. Instead, he took advantage of this opportunity and leisurely taught Inspector Komatsu the steps to examine the corpse.

Otherwise, if the police coroner continues to be like this

It's really unsettling.

There is a standard procedure for examining the corpse form. If you follow the procedure from beginning to end, even if you can't see the truth clearly, you can at least remember the clues.

"You fill in the deceased's name, testing location, testing time and other information yourself."

"Then, first measure the temperature of the autopsy environment and the relative humidity of the autopsy environment."

Lin Xinyi picked up the thermometer and hygrometer from the tool box and took some measurements:

"Ambient temperature, 35.5."

"Relative humidity, 46%"

Inspector Xiaosong nodded in agreement, holding a pen and paper to write down.

"Let's start with a few macroeconomics:"

Lin Xinyi took out the tape measure from the tool box and measured carefully:

"Length of corpse: 161cm."

"The skin color is pale, no jaundice, development is normal, nutrition is good, and there are no deformities in the limbs."

"There are no spots on the corpse. There is no rigor mortis. There are no signs of decay. The muscles are relaxed by acupressure."

"Skip this one for now."

The best places to measure the temperature of a corpse are the rectum and liver. Nowadays, it is inconvenient to check with so many people around.

"After recording these items, we will examine all parts of the body from the beginning."

"Here you start from the head and check from top to bottom."

"First, the head and face:"

"Hair, black, long and broken, 8cm long at the top."

"Auricle, no abnormality. External auditory canal, no abnormality."

"There are scratches on the external nose. No abnormal secretions in the nasal cavity."

Lin Xinyi was actually slightly off topic.

He said he would use evidence to send Ishikawa in, but now he is taking advantage of the opportunity of the autopsy to conduct on-site teaching for Komatsu's inspection.

But everyone present did not question his procrastination, but instead watched with great enthusiasm.

Because Lin Xinyi has a different style from all the famous detectives before.

When he handles cases, he mainly focuses on corpses, and his investigation methods are as clear and orderly as the factory assembly line, and are extremely standardized.

Other detectives are like so-called "craftsman" masters, relying on their hard-to-replicate craftsmanship.

Lin Xinyi, on the other hand, operates an industrialized production line with strict standards and clear organization.

"Attention is coming."

Just when everyone was watching carefully and Xiaosong was listening carefully, Lin Xinyi suddenly increased his tone.

While measuring the size of the wound with the ruler he took out of the tool box, he said calmly:

“A 2.0 cm×0.3 cm contusion wound was seen in the middle of the forehead.”

“A depressed skull fracture measuring 4.0 cm×3.0 cm was found from the left forehead to the lateral side of the left eyebrow arch, accompanied by two contusions measuring 1.0cm×0.6cm and 2.0cm×1.0cm respectively.”

"There were no symptoms of bleeding, swelling, or tissue shrinkage in the above wounds, and the wounds turned yellow-brown."

As he spoke, he deliberately stopped describing and turned his attention to Xiaosong for inspection.

Sure enough, Xiao Song looked back at him with a blank expression.

Even with the food in his mouth, this guy still didn’t hear anything.

"well"

Lin Xinyi sighed helplessly:

"The deceased had a skull fracture, and the facial injuries were concentrated. It can be seen that they were formed at one time."

"Coupled with the extensive abrasions located on the exposed parts of the limbs, it can be basically determined that these injuries were caused by falling from a height."

"That is to say, the deceased did fall from the building."

Finally understanding the meaning, Ishikawa on the side immediately roared urgently:

"Doesn't that mean that Uchida committed suicide by jumping off the building?"

"Any more questions?"

"Of course." Lin Xinyi temporarily gave up teaching Xiaosong on patrol. This guy was obviously a rookie who couldn't be brought up in a while.

He looked at Ishikawa coldly and began to focus on revealing the truth:

"The deceased fell down from the building."

"But I didn't say that he jumped down from the building alive."

"Because, I just mentioned it"

"Although the surface injuries on the corpse are consistent with the characteristics of high-fall injuries, most of the wounds on the head and face and the abrasions on the body surface are yellow or tan, and there are no life-related reactions such as bleeding, swelling, and tissue shrinkage."

Life reaction is a defensive reaction that occurs locally and throughout the body when a person is violently injured while still alive.

Once a person dies, all body functions stop functioning, and if the person is injured by external force at this time, the scars will be completely different from those suffered during life.

"Ishikawa, do you think your trick is very clever?"

"Just find a forensic doctor and check whether the wound has any reaction from life, and you can determine whether the deceased was injured before death or after death."

"As for the deceased this time, there is no doubt that he did not die from falling from a height."

"The real cause of his death depends on this."

Lin Xinyi produced ironclad evidence to prove that the deceased did not die by jumping off the building at all.

Then, he slightly raised the deceased's head with his hands so that everyone could see his neck clearly:

"There is vague subcutaneous bleeding on the neck, which is distributed on both sides of the throat. It is obviously a strangulation mark on the neck caused by violence."

"This shows that the deceased had been strangled by someone's neck forcefully before his death."

"What, what's going on?"

Regarding this point, Ishikawa had already thought of an excuse to deal with it:

"I beat Uchida with Aoki not long ago."

"Although I strangled his neck, I didn't strangle him to death. It was just a normal fight."

He directly admitted his bullying behavior.

But at the same time, Ishikawa clearly separated the death of himself and Uchida.

After all, the presence of strangulation marks can only prove that he strangled Uchida's neck, but there is no way to prove that Uchida was strangled to death by him.

But Lin Xinyi just said to him coldly:

"Stop fantasizing"

"Do you really think it's as simple as that I can only see choke marks?"

"If I can't even confirm the true cause of death of the deceased, my book will be in vain."

As he spoke, he leaned down again and carefully opened the deceased's eyelids with his hands:

"As you can see, the deceased's eyelids and bulbar conjunctiva were congested, accompanied by dense bleeding points."

"What is this? Why is there this bleeding?"

"The occurrence of this kind of petechial bleeding is related to the increased vascular permeability, capillary rupture, and increased blood pressure caused by asphyxia and hypoxia. It often occurs at the time of asphyxia or within 15 to 30 seconds."

"The deceased had symptoms of congestion on his face, and his complexion was cyanotic and purple."

"This is because the deceased suffered neck compression during his lifetime, which resulted in obstruction of the venous return of the head and face, severe blood stasis, and an increase in reduced hemoglobin in the blood, resulting in cyanosis and swelling of the face."

Lin Xinyi's gaze was like a sword, pointing directly at Ishikawa's already weak psychological defense:

"What I just said are the basic symptoms of death by suffocation."

"There are such symptoms, plus it has been confirmed that the injury was caused by a high fall after death."

"It is enough to prove that the deceased died of mechanical suffocation caused by external force, rather than committing suicide by jumping off the building."

"And this murderer who killed him"

"It's not hard to find at all."

Lin Xinyi raised the deceased's hand and let everyone see his fingertips:

"There were obvious resistance and restraint injuries on the deceased's wrists, indicating that he resisted when being beaten by the murderer."

"Although he is dead, his resistance was not completely ineffective."

"At least he left evidence in his fingernails."

"His fingernails contained dander from the murderer's skin. By identifying the DNA of the dander, we can identify the murderer."

"And the murderer probably still has scratches on his body caused by the deceased's resistance."

"I"

Ishikawa's expression changed, and he subconsciously covered his arm with bloodstains on it.

"So what if there are scratches?"

"I told you, I beat Uchida before. Isn't it normal for him to have my skin flakes in his nails?"

"idiot!"

Lin Xinyi laughed angrily at this die-hard murderer:

"Didn't I prove the true cause of Uchida's death?"

"Since he died of homicide and asphyxiation, not suicide by jumping off a building"

"Then these skin scraps are enough to serve as key evidence to identify the murderer!"

"Ishikawa"

There was a different kind of oppression in his voice:

"The irrefutable evidence is in front of me, what else do you have to say?"
