Although Qiao Chuan is not deeply involved in the autopsy, he still knows the reason for the formation of this white patch, the blood is in a state of flow when people are alive, and the blood of the human body is in a state of non-flow when they are dead.

If the murderer presses and squeezes the victim vigorously when killing someone, the blood does not circulate in the part that is compressed, and after the victim dies, because the blood in the whole body is in a state of incirculation, there will be bloodless white spots in the squeezed area.

So it shouldn't be that Li Li didn't die when she fell to the ground, but that she was already dead when she fell to the ground.

Could it be that Li Li was lying down at first, and then struggled to straighten up before being strangled to death?

Qiao Chuan told Chen Ru about his doubts.

Chen Ru seemed to have taken this into account during the autopsy, so she said:

"I thought the same way at the time, but if Chen Ru was standing when she died, then according to the height of a normal person, the position where the white spots appeared would not be right."

"Ao ......" Qiao Chuan suddenly figured out that if he pressed against his knees, the white spots should appear in the lower part of the waist, not in the upper part of the waist.

Chen Ru helped Qiao Chuan look through the autopsy report, "Here, you see, Li Li's shirt was thrown aside, and the chest of the shirt appeared with the same texture as the scene of the crime. ”

"You mean, Li Li was lying on her stomach when she died?"

"Yes."

"But ......" Qiao Chuan wanted to say why Li Li's face was not very dirty, and then he suddenly figured out that it was rain.

In this way, there is a rough picture of what is happening on the ground:

The murderer attacked Li Li from behind, at this time Li Li was in a semi-lying position, resulting in a dent on the ground caused by the impact of the heel of the high heel on the ground, Li Li grabbed the murderer's leather clothes with his hands, and then the murderer pushed Li Li with his knees, Li Li climbed down, and wrote the death message on the ground with the word "Feng" missing.

Then after Li Li died, the murderer placed Li Li lying on her side, and then for some reason, the murderer waited for an incident, and then moved Li Li's body to another place, which led to the appearance of corpse spots on Li Li's body in two places, the side and the back (corpse spots are caused by the fact that after the death, the blood no longer circulates and pigmentation is caused).

It's weird, but if you look at all the clues at the scene, it can only be like this, even the weirdest way of death. Unless......

"Haven't the families of the deceased been contacted?" Li Li's words dragged Qiao Chuan's thoughts back.

Qiao Chuan shook his head.

"Is the procedure the same as before?" Chen Ru asked.

"Well, after all, it's a criminal case, and I'll sign the autopsy notice."

Qiao Chuan looked at the time, it was almost seven o'clock, it was April, and it was already dark outside. Chen Ru asked her colleagues to preserve the body and wait for her family to take her away.

Chen Ru went to the sink to wash her hands with soap over and over again, and was about to go back to the office to change out of her police uniform and go home, when Qiao Chuan stopped her.

"Chen Ru, why don't we have dinner together in the evening."

Qiao Chuan and Chen Ru live away from the police station is still some distance away, here is the economic development zone of Sancao City, just when Sancao City was established, it became the area of the city's zf focus on development, all aspects of the infrastructure are relatively perfect, due to the large-scale relocation of schools, hospitals, shopping malls, and the development of the country's well-known real estate development enterprises "Lvguiyuan" has made the housing prices here soar, and the housing price appreciation rate in Jiangbei Province is also "among the best", but it is worth affirming that the living environment here is still very good, Not as noisy as the old town.

The two of them live in two communities, but their communities are not far away, because of work, many people in their police station live here, get some preferential policies, and the unit price of buying a house is much cheaper.

This place is a relatively prosperous area in the whole economic development zone, next to the community is a landscape lake in Sancao City, this lake was originally a kiln factory, under the development of ZF, here is turned into treasure, the development here has a shape, especially the music fountain, known as the largest music fountain in the Jiangbei area of Jiangbei Province, but also attracts a lot of tourists from other places.

The restaurant they went to was right next to the lake, and they had a great view of the lake and its musical fountain through the window.

"Want something?" Qiao Chuan tilted his neck and drank all the water in the cup, today's investigation made him so busy that he basically didn't have time to drink water.

"Whatever." Chen Ru drank water, turned her head to the direction of the window, and looked at the fountain in the lake that ebbed and flowed with the music.

Qiao Chuan looked at Chen Ru's face and was in a daze, the eyes staring into the distance seemed to have a kind of magic, melancholy and gentle, under the white and slightly straight nose bridge were pale red lips, these lips were attached to the cup held in her master's hand, he wanted to be this cup, but this thought only flashed from his mind, and he quickly put away this evil thought.

Chen Ru also seemed to see Qiao Chuan looking at him, his cheeks couldn't help but blush slightly, and he twisted his head.

"What do you see me doing?"

Qiao Chuan also withdrew his gaze to the recipe in his hand.

"Isn't it to see what you want to eat?"

"Can you tell?" Chen Ru seemed to be very serious.

Qiao Chuan shook his head.

"Let's have sweet and sour pork ribs, this sweet and sour pork ribs is not bad."

"Eating meat is slow to digest, and excessive peristalsis of the stomach and intestines at night affects digestive function."

"Then come to a coiled dragon eel, it's been a hard day, and it's a big supplement."

"The fried oil is too hard, and the spicy affects the stomach."

"Let's have a dessert."

"It's not good to have dessert at night......"

Qiao Chuan pushed the menu in his hand in front of Chen Ru,

"You come, you come."

Chen Ru glared at Qiao Chuan, flipped through the recipe and handed the recipe to the waiter beside him.

"One stir-fried snow peas, one stir-fried broccoli, one shiitake mushroom greens, one tomato egg soup."

"You're scraping the oil off my stomach." Qiao Chuan pretended to be angry.

"Eat at night, take more vitamins, fiber helps bowel movements."

Narrator: Your waiter couldn't hold back her laughter when she heard this, she didn't think that such words came from such a big beauty, but she didn't understand that the beauty next to her always didn't care about these things when she dropped out of the first year of college and retook the college entrance examination that year.

Qiao Chuan only knew part of Chen Ru's affairs, he knew that Chen Ru's original university was an architecture university, and he also studied architecture, but he stopped going to it when he was a freshman, but returned to high school to retake the college entrance examination, and his first choice for the college entrance examination was forensic science at the Provincial Police College, but he didn't know the reason, and the only one who really knew the reason was Chen Ru. No, there should be another person.

Qiao Chuan has always been a talker during dinner, Qiao Chuan is not like this in ordinary life, Qiao Chuan likes to think quietly alone, then read books at home, and then flip through some criminal cases in various places, but when facing Chen Ru, I don't know what's wrong, I always can't help but want to say a few more words to her. As a result, tonight was the same as usual, except for some things about today's case Chen Ru gave some answers, and when he said other things, Chen Ru always said "um" perfunctorily.

"Who are the perpetrators of the rape?" Chen Ru lowered his head, put his arms on the table, and his eyes pressed against the tableware on the table, this sentence Qiao Chuan didn't know if Chen Ru was asking himself or talking to himself.

"The scum of society, the dregs, the psychologically twisted people." Qiao Chuan thought for a moment and replied.

"Then you say, how likely are criminals like this to commit crimes in a row?" Chen Ru put up his hands to support his chin, his eyes still looking at the tableware on the table.

"From a psychological point of view, this kind of continuous crime is very likely, but if there is no homicide, the possibility of this kind of criminal being arrested is extremely small, not because the police are not doing well, but because many victims take into account the opinions of the people around them and do not report the crime." Qiao Chuan wondered why Chen Ru would ask such a question, but he didn't ask her why, he believed that if Chen Ru wanted to let him know, she would definitely tell him.

Chen Ru sighed, stopped talking, turned his head, and looked out the window at the landscape park.
