Lin Xinyi slowly walked to Uchida's body.

Uchida still lies quietly on the ground, the victim of bullying who did not receive enough attention during his lifetime, and finally receives the belated attention of the police and society after his death.

"Gloves."

Just like the attending physician who was busy during the operation, Lin Xinyi directly reached out and asked the police officers present for tools.

"Here." A young police officer hurriedly stepped forward with a forensic investigation box.

When I looked closely, it was the old acquaintance I met in the morning, Komatsu, who was a part-time coroner.

He was the coroner when Lin Xinyi was away, and now seeing Lin Xinyi's presence, Komatsu automatically demoted himself to the status of a suitcase assistant.

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

"Two pairs..."

Lin Xinyi looked helplessly at this "peer" who couldn't do it.

"Uh..."Xiao Song's face turned red, and he hurriedly made up for Lin Xin's hand.

And Lin Xin put on gloves neatly with one hand and foot, and looked at Komatsu's inspection meaningfully:

"Let me do the autopsy for you this time..."

"You write down what I say in order."

"Good!" Komatsu readily agreed, but he didn't know how to check it himself.

At this time, Lin Xinyi finally started to act.

He did not rush to tell the truth of the case, but took this opportunity to unhurriedly teach Komatsu the steps of the autopsy examination.

Otherwise, if the police coroner keeps going on like this...

It's really reassuring.

And there is a set of standard procedures for this corpse examination, and you can follow the procedure from beginning to end, even if you can't see the truth clearly, at least you can help remember the clues completely.

"You can fill in the name of the deceased, the place of testing, the time of the examination and other information."

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

Lin Xinyi picked up the thermometer and hygrometer from the toolbox and measured:

"Ambient temperature, 35.5."

"Relative humidity, 46%"

Komatsu nodded yes and took a pen and paper to the side.

"Let's start with a few more macro items:"

Lin Xinyi took out a tape measure from the toolbox again and measured carefully:

"Corpse length: 161 cm."

"Pale complexion, no yellowing, normal development, good nutrition, no deformities in the limbs."

"Corpse spots, none. Zombie, none. Signs of corruption, none. Acupressure feels the muscles relax. ”

"Corpse temperature... Forehead... Skip this one for now. ”

The best places to measure the temperature of the corpse are the rectum and liver, and now there are so many people around that it is inconvenient to check it.

"With that in mind, we'll start examining the various parts of the body."

"It's a top-down inspection that starts with the head."

"First of all, the head and face:"

"Hair, black, long shredded hair, long hair at the top... 8cm。 ”

"Pinna, no abnormality. External auditory canal, no abnormality. ”

"Outer nose, there are abrasions. Nasal cavity, no abnormal discharge was observed. ”

Lin Xinyi is actually a little off-topic.

He said that he would send Ishikawa in with evidence, but now he took the opportunity of the autopsy to start on-site teaching for Komatsu's inspection.

But everyone present did not question his procrastination, but watched it very devotedly.

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

He mainly focuses on the corpse in handling the case, and the method of investigating the case is like now, which is as clear and orderly as the factory assembly line, and is extremely standardized and standardized.

The other detectives are like so-called "ingenuity" masters, who excel with their hard-to-replicate craftsmanship.

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

"Attention... Here's the point. ”

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

He measured the size of the wound with the ruler he took out of the toolbox, and said in a calm tone:

"A 2.0 cm × 0.3 cm contusion wound was seen in the middle of the frontal region."

"A 4.0 cm×3.0 cm depressed skull fracture with two contusions of 1.0 cm× 0.6 cm, 2.0 cm, × 1.0 cm in size from left frontal to lateral left brow arch."

"There was no bleeding, swelling, or tissue contraction in the above wounds, and the wounds were yellow-brown in color."

As he spoke, he deliberately stopped describing and set his eyes on Komatsu for inspection.

Sure enough, Komatsu looked back at him blankly.

The food is fed to his mouth, and this guy still hasn't heard anything...

"Ugh..."

Lin Xinyi sighed helplessly:

"The deceased had a skull fracture, and the facial injuries were concentrated, and it can be seen that it was a single formation."

"Plus extensive abrasions located on the exposed parts of the limbs... It can be concluded that these injuries were caused by falls from heights. ”

"In other words, the deceased did fall from the upper floor."

finally understood the meaning, and Ishikawa on the side immediately roared in a hurried tone:

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

"Still, do you have any questions?"

"Absolutely." Lin Xinyi temporarily gave up teaching Komatsu to inspect it, this guy is obviously a pure rookie who can't be brought up for a while.

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

"The deceased fell from the stairs, yes."

"But I didn't say he jumped from the stairs alive."

"Because, I just mentioned..."

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

Life response is a defensive response that occurs in the injured area and the whole body when a person is violently injured in a state of survival.

Once a person dies, various bodily functions stop functioning, and then he is injured by an external force, the scarred state will be completely different from the injury before death.

"Ishikawa, do you think you're clever at trickery?"

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

"And this time the deceased, he undoubtedly did not die from a fall from a height."

"The real cause of his death... It depends on here. ”

Lin Xinyi came up with iron-clad evidence to prove that the deceased did not die by jumping off the building at all.

Then, with his hand, he lifted the deceased's head slightly, so that everyone could see his neck:

"There is a faint subcutaneous hemorrhage in the neck, distributed on both sides of the throat, apparently a neck strangulation caused by violence."

"This shows that the deceased was strangled by the neck before his death."

"W-What about this..."

Regarding this, Ishikawa has long thought of an excuse to deal with it:

"I beat Uchida with Aoki not long ago."

"I choked him by the neck, but I didn't strangle him... It's just a normal fight. ”

He directly admitted to his bullying.

But at the same time, Ishikawa divided himself and Uchida's death cleanly.

After all, having a strangulation can only mean that he choked Uchida's neck, and 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 that I can only see the strangulation?"

"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 dead man's eyelids with his hands:

"You can see that the deceased's eyelids and bulbar conjunctiva are congested with dense bleeding spots."

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

"The occurrence of this petechial hemorrhage is associated with increased vascular permeability, capillary rupture, and increased blood pressure due to asphyxia and hypoxia, and usually occurs at the time of asphyxia or within 15 to 30 seconds."

"The deceased's face was bruised, his face was cyanotic, and he was blue-purple."

"This is because the deceased suffered compression on the neck before his death, which led to obstruction of venous return to the head and face, severe blood stasis, and increased reduction of hemoglobin in the blood, resulting in cyanosis and swelling of the face."

Lin Xinyi's eyes were 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 it was a high fall injury caused after death..."

"It is enough to prove that the deceased died of mechanical suffocation caused by external forces, and not committed suicide by jumping off a 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:

"The deceased had obvious resistance and restraint injuries on his wrists, which indicate that he resisted when he was beaten by the killer."

"He may be dead, but his resistance is not entirely fruitless."

"At least, he left evidence in his fingernails."

"He has dander from the killer's skin in his fingernails, and by identifying the dandruff's DNA, the killer's identity can be identified."

"And on that murderer... I am afraid that there are still scratches caused by the deceased's resistance. ”

"I..."

Ishikawa's face changed, and he subconsciously covered his arm that was showing bloody marks.

"What if there are scratches?"

"I said, I've beaten Uchida before, isn't it normal for him to have my dander in his nails?"

"Idiot!"

Lin Xinyi was angry with this die-hard murderer:

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

"Since he died of suffocation by homicide, not by suicide by jumping off a building..."

"Then these dander are enough to serve as crucial evidence to identify the murderer!"

"Ishikawa..."

There was a different kind of oppression in his voice:

"What else do you have to say?"
