After being bound by the cute new system, I took the whole place flying

Si Qing looked at Xiao Mo and saw the man winking at him, and couldn't help but raise his eyebrows slightly.

"Okay, police officer, my son is now in your hands. Please be sure to find the real culprit who hurt my son!"

Xiao Mo nodded to the two of them, then picked up the family consent form that he had put aside and handed it to the two of them.

After sending the two people away, Si Qing asked them to go up the path and go to the sink to prepare.

"Mr. Shang, you also think this is not a simple accident, right?"

Xiao Mo sat on a chair to the side, watching Si Qing's movements, the smile in his eyes was unstoppable.

"The results haven't come out yet, so nothing is conclusive."

In fact, Si Qing is more inclined to believe that this is a deliberate murder. After all, the water in the hot spring pool is so deep. Even if you are not familiar with the water properties, the possibility of drowning in the hot spring pool is still very low.

"Wang Han is a pure northerner and has little opportunity to go on a cruise. In addition, his family is not that wealthy and cannot afford swimming lessons, so his water quality is very poor."

Xiao Mo stretched out his hands, folded them behind his head, and leaned back until the back of his hands touched the cold wall, then he stopped.

"So Captain Xiao is more willing to believe that he drowned in the hot spring pool?"

The final sound of the last five words rises, which is quite unbelievable.

Xiao Mo smiled good-naturedly.

"The results haven't come out yet, and I can't make a conclusion. Let's start with forensic medicine."

Si Qing raised his eyebrows, took the gloves from Xiao Lu and put them on.

Xiaolu turned on the recorder on one side, then stood aside and watched Si Qing's movements intently.

"There are many causes of drowning. The simplest external factors include mental disorders caused by alcoholism, disease or drug abuse, which may lead to the deceased's death by drowning."

After Si Qing finished speaking, Xiao Mo raised his eyebrows and said slowly:

"We have conducted a preliminary investigation on the deceased. The deceased was in good health. There was an incident where a heart patient suffered an accident in the hot spring pool half a year ago. Therefore, the hot spring hotel has special requirements for tourists and requires tourists to provide information for the past six months. From the recent physical examination report, we learned from the hotel that Wang Han is in good health, and from the observation at the scene, there were no bottles or the like around, which can roughly rule out the conditions you just mentioned."

Si Qing nodded slightly.

Then, he took out the scalpel from the plate on one side and made an arc-shaped transverse incision on the corpse.

From the left acromion through the suprasternal notch to the right acromion, a straight incision is made downward from the midpoint of the transverse line, going around the left side of the umbilicus to the upper edge of the pubic symphysis.

"Sister Qing's T-shaped cut is so beautiful."

Xiao Lu admired from the side.

Si Qing raised his eyebrows slightly.

"There are three ways to dissect a cadaver: linear Y-shaped and T-shaped. Remember, no matter what kind of incision is made, it should be done after checking the appearance. If there is damage, the cut line should go around the damage. When making an incision, The knife surface is vertical, and the index finger presses the back of the knife with appropriate force to make the wound edge flat. The incision should be as deep as the subcutaneous tissue."

Xiaolu nodded repeatedly, remembering everything Si Qing just said in his heart.

Although his sister Qing looks a little cold on the face, she is actually quite gentle.

At least the last forensic doctor had never taught him knowledge so patiently.

[Su, host, aren't you afraid? ]

'What's there to be afraid of? He can't open his eyes and kill me. '

Si Qing looked at the situation inside the corpse and became more focused little by little.

"A large amount of foreign matter such as foam and algae appeared in the airways and alveolar cavities."

Xiao Lu was recording what Si Qing just said, and Xiao Mo asked:

"Algae foreign body, what does this mean?"

Si Qing turned around and glanced at Xiao Mo.

"Whenever people die from drowning, it is often found that most of the patients who die from drowning will have a large amount of white or light pink foam, algae and other foreign bodies in the trachea, mouth, and nostrils."

"This is mainly because when people drown, they are unable to breathe on their own in the water, causing choking and coughing. This causes water to enter the human respiratory system and stimulate the respiratory mucosa to secrete a large amount of mucus, which leads to an increase in the pressure in the brain vesicles and blood vessels in the human body. Rupture, swelling, congestion and hemorrhage of the mucosal epithelium of the larynx, trachea and bronchi, leading to the appearance of a large amount of white or light pink foam and algae and other foreign matter in the human trachea, alveolar cavities, mouth and nostrils."

Xiao Mo pursed his lips.

"In other words, this man did drown to death?"

Si Qing said nothing.

Then, the scalpel was pointed at the position of the corpse's intestines and 12 denums.

"For now, the cause of death is indeed due to drowning, but..."

Xiao Mo quickly understood what Si Qing meant.

"You are doubting that he did not die in the hot spring. The hot spring is not the scene of the first crime."

Si Qing nodded slightly, and the interest in Xiao Mo's eyes became more and more intense. This person had the same idea as him!

When he went to inspect the site today, he noticed something was wrong. It was not because he found something, but because the site was too clean.

No trace at all.

He has been working as a criminal police officer for so many years, and he has never encountered such a clean crime scene. It was so clean that it was strangely clean.

He had an idea at that time that the hot spring was not the scene of the first crime, so he called in surveillance from the hotel and found that there was a young man and a young woman traveling with Wang Han.

However, these two people were not seen at the scene. He has already sent someone to summon them. I believe there will be news soon.

"Drowning victims generally have drowning liquid and foreign bodies in the stomach and duodenum. This is mainly because when the drowning liquid is inhaled into the lungs, it may be swallowed into the human stomach and enter the human body. into the duodenum.”

Si Qing said, preserving the drowning fluid extracted from the stomach of the deceased.

"Captain Xiao, there is a test tube bottle on the table not far from you. It is the evidence I took from the hot spring pool. Please send it to the forensic department and let them do a diatom experiment."

Xiao Mo took the two test tube bottles in his hands and looked at Si Qing who was still checking them.

"Can you please explain to me the principle of the diatom experiment?"

Si Qing glanced at Xiao Mo and pursed his lips when he saw that the man was serious about studying. After a moment, an ethereal female voice sounded.

"Diatom testing technology is one of the important testing methods currently used by forensic doctors at home and abroad to identify whether a body died from drowning."

"Diatom detection technology is mainly a method of detecting diatoms in the internal organs of corpses and conducting qualitative and quantitative analysis of diatoms. If the analysis and identification results of diatom detection technology in the internal organs of corpses of drowning victims If it is positive, and the type of diatoms is consistent with the water samples on the ground, it can be determined that the body died of drowning."
