Hu Pengjun has always felt that Jiang Wei is a piece of material for being a criminal policeman, but he is helpless because the other party is not here, but he wants to take this opportunity to test the other party to see how many goods the other party has in his stomach.

"Hmm."

Jiang Wei glanced at Tian Hongfa, who pretended to come over to check the situation, and explained:

"I have come to this conclusion because I have made a cursory examination of this corpse and have made two points.

First, the corpse's pupils were visibly dilated, with a small amount of blood remaining in the mouth and nose, and the skin was blue-black, the pores were dilated, and the scalp secreted some oil-like fluid.

Judging from these circumstances, it is very likely that this cleaning aunt was strangled by something and caused mechanical suffocation, but at that time, in order not to destroy the scene, I did not turn over the body to check the situation of the other party's neck.

According to my understanding, if a person dies of asphyxiation, within a minute, the heart will speed up to between 120 and 200 beats per second, and then the heart will slow down more and more because of the lack of oxygen supply to the blood, until the heart stops after two or three minutes.

During this period, the pupils will be very dilated, and there will be a small amount of congestion, the skin and conjunctiva will also secrete some oil-like fluid, sometimes a small amount of blood will seep out, and its color will also change from normal to blue-purple, or purple spots, livedo and other symptoms will appear.

It's just that something seems to have happened to this corpse, and it is indeed blue and black all over. ”

Jiang Wei explained at a glance that everything was answered by relying on the information he found on the Internet, and he did not exaggerate the facts at all.

"The second possibility is that when a person is frightened, the adrenal glands will secrete a large amount of catecholamines in a short period of time, and this neural medium will prompt the heart to accelerate sharply in an instant, and the blood pressure will also rise, resulting in an exponential increase in the oxygen consumption of the heart machine.

As a result, the rapid circulation of blood can tear the heart muscle fibers, causing the heart to bleed profusely, and in just a few seconds, the person's heart will stop beating, accompanied by a small amount of blood rushing into the mouth or nasal cavity.

And these symptoms are shown on the corpses on the ground, so I guess that this cleaning aunt must have died of someone's injury, not a heart attack. ”

Speaking of this, he looked up at the policeman who had reported to Tian Hong that he had died of a heart attack, and continued:

"As we all know, heart disease patients have a characteristic, that is, they are very painful when they are sick, and if they take medicine in time, they can recover slowly, but if they are not in a hurry, then their hearts will stop beating within a minute.

This will only lead to shock to the patient, and if it is still treated in time and handled properly, it may also be pulled back from the clutches of death.

But if there is no one around, the patient will die completely within three minutes.

As a result, the symptoms manifested are that the mouth is wide open due to heavy breathing before death, the expression is distorted due to pain, the pupils are dilated, the whole body is flatulent and the abdomen is swollen, the limbs may convuls, and even the urine and urine may be incontinent.

Another is that the extremities of the limbs will become blue due to carotid artery arrest, and the skin will also have symptoms such as spots and bruises.

Of these manifestations, I didn't see any other similar symptoms, except for the relative coincidence of the pupils, so I guessed that he didn't die of a heart attack. ”

Jiang Wei's words calmed everyone present, even Ye Yanran, who had been following him and was about to shrink into his arms in fright when he saw the bloody handprints on the corpse and glass, also raised his head and looked at him with a look of adoration.

"Yes, the basic skills are very solid, it turns out that I was wrong before, you are not only suitable for the criminal police, but also have the potential to become a doctor."

Hu Pengjun nodded, undisguised the look of appreciation in his eyes.

And at this moment, the forensic doctor who was squatting on the ground to examine the corpse also stood up and nodded while dragging the gloves on his hands and said:

"Little brother Jiang Wei is right, judging from the appearance of the corpse, she did die of suffocation and fright, but I can't see this kind of blue and black performance for the time being, and I can't get a conclusion until I go back to dissect."

"Do you have any clues over there?"

Hu Pengjun turned his head to the criminal policeman who was holding a purple light to shine around:

"In addition to the bloody handprints on the mirror, there are other clues found for the time being."

"Well, then you will investigate one after another, be careful, and don't miss any suspicious points."

After Hu Pengjun finished explaining, he turned his head and asked Tian Hongfa:

"Who was the first person to find a body?"

"This, this...... I'll ask. ”

Tian Hongfa looked embarrassed, and hurriedly asked Manager Wang to go.

Seeing this situation, Hu Pengjun also shook his head, and sighed with hatred:

"This Tian Hongfa is really ......"

Turning around, because Jiang Wei was present, he didn't say anything too ugly.

"Xiao Li, go and take a look at the surveillance."

After explaining to the only remaining young criminal policeman who followed him, Hu Pengjun turned his gaze to Jiang Wei again.

"What do you think about this case?"

At this time, he was also thinking about how to direct the other party's attention in the direction of the septic tank.

It is naturally impossible to use normal means, not to mention how he knew the situation inside, even if he wants to connect this matter with the sewer, it is unlikely.

At this time, when he heard Hu Pengjun's inquiry, after thinking about the wording, he said slowly:

"Team Hu, maybe you don't know, when Yan Ran came to the bathroom before, she didn't find anything abnormal, and according to what she said, but Aunt Dejie also behaved very normally.

But less than three minutes after she came out of the bathroom, the cow in the bathroom screamed, is there some time in it?

I mean, those handprints, such big mirrors, are imprinted in two or three minutes, it's impossible for one person.

Looking at the direction of its expression, it is clear that it is printed on it with abrasives and other objects, otherwise it will not show the opposite direction. ”

The moment Jiang Wei drew everyone's eyes to the top of the mirror, he called out the double-faced Kui from the soul cultivation bead, but fortunately, it was still Su Yiyi who woke up this time.

Then he turned his head to the side, and quickly explained to the other party with his mouth, and then turned his head back and said:

"So I guess that this cleaning aunt saw something terrible in these three minutes that caused her to be frightened, and because she was suffering from some kind of disease, she fell to the ground, and her body showed such strange changes?"
