In the foul-smelling sewers, the four of us conducted a carpet search, but found no human tissue. It can be concluded that the murderer only threw Zhou Yi's head into the sewer.

On the edge of the well, Ren Qiushi and Zeng Lan conducted a preliminary autopsy on the salvaged human head.

The human head has been soaked in the sewage of the sewer for a long time, the skin has become puffy, and the eyes are turned out, which is very hideous and terrifying.

Ren Qiushi groped carefully on the skull of the human head and felt a depression in the back of the head, which was an obvious skull fracture.

"Can you determine the cause of death?" I asked him,

"The deceased suffered a blunt object blow that fractured his skull and caused an intracranial injury. A skull fracture of this severity can be absolutely fatal, causing severe intracranial hemorrhage and head injury, and although it will not be fatal immediately, it will definitely die in a short period of time. As Ren Qiushi spoke, he suddenly retracted his hand like an electric shock.

"What's wrong?" Zeng Lan, who was beside him, asked with concern.

Ren Qiushi calmed down, gently brushed the deceased's hair with both hands, and saw that there were many dense small wounds and bleeding spots on the deceased's scalp.

He felt near the wound and came across a sharp raised object, Zeng Lan opened the forensic toolbox, took out a tweezer from it and handed it over.

Ren Qiushi took the tweezers, gently pulled out the sharp object inserted into the scalp, and looked carefully at the sunlight.

This is a dark red glass shard the size of a fingernail of a small thumb that looks like a shard of a glass.

"The killer used a glass object and hit the deceased's skull hard, causing the deceased's skull to be fractured." Ren Qiushi put the glass bottle into the evidence bag and said in a deep voice.

Ren Qiushi suddenly felt that something was wrong, and thought about it carefully, it could cause such a serious skull fracture injury, and the glass would never be able to hit the head hard, so this glass product was likely to be a wine bottle, and this dark red wine bottle was very likely to be a red wine bottle.

After hearing Ren Qiushi's conclusion, I couldn't help but associate this red wine bottle with the red wine produced by Baiyun Food Company. Because so far, every time there is a crime scene, there is a red wine produced by this company.

"The wound on the deceased's neck was uneven, the skin was torn, and the skin wound was jagged, which is consistent with the fact that the corpse dismemberment tool used by the murderer was a dagger." Ren Qiushi carefully checked the state of the deceased's skull again and said seriously.

"Can you determine the exact cause of death?" I asked.

Ren Qiushi thought for a while, shook his head and replied: "The head has been soaked in the sewer environment for a long time, and the sewer environment is dirty and bacterial, resulting in the skull already showing the situation of a giant, and the time of death is difficult to judge. I need to take my head back for an autopsy to check for damage in my brain so I can determine the exact time of death. It is now confirmed that the killer hit the deceased's skull with a wine bottle, and then cut off the deceased's head with a dagger to complete the dismemberment. ”

I took a closer look at the environment of this back street, which is located behind the main road in the downtown area, and although it is secluded, it is often walked around. The killer chose to throw his head into the well, and he would have avoided the eyes of passers-by in the dead of night.

This also shows that the murderer is very familiar with the neighborhood and chose this back street without monitoring facilities, and it also shows that the murderer must live nearby.

No traces of blood were found along the road, indicating that the murderer did not immediately throw the body after the murderer, but after cutting off the head, it was kept for a period of time, and the body was thrown here after the blood dried up. This is also in line with Ren Qiushi's previous judgment, but why did the murderer keep the body for a period of time after the killing? The palms and fingers were quick-frozen, but the head was not quick-frozen, but discarded.

It's all really weird.

I have marked all the places where the clues in this case have appeared on the map.

Fried chicken restaurants in Nanshi, fried chicken restaurants on Renmin Street, Western restaurants on Zhengjie, and water wells on Back Street......

I suddenly found that the sewer on the back street was the closest to the western restaurant on the main street, only one street away, and I could walk directly through the residential area, and all the surveillance facilities could be avoided along the way.

Don't......

"Lao Qin, if it's nothing, I'll go back to the forensic department for an autopsy." Ren Qiushi stood up and said to me.

I came back to my senses and replied, "Okay, you guys go get busy first." ”

Didi –

Suddenly there was the sound of a car honking on the side of the street, and I looked curiously to see a silver-gray van parked on the side of the road, and there was a fried chicken restaurant on the side of the road.

After what happened in Nanshi and Renmin Street, I already have a different kind of "emotion" for fried chicken restaurants.

After a whistle, a man came out of the fried chicken restaurant, who was supposed to be the owner of the fried chicken restaurant.

The car door opened, and a young man in his thirties came out of it, with a very strong physique, and the two met and talked, and the young man could also produce a notebook for the owner of the fried chicken restaurant to sign.

"What are you looking at?" Officer Wang walked up to me and asked me.

I smiled and said lightly, "Look at the delivery." ”

"What's so nice about the delivery." Officer Wang laughed, puzzled by my behavior.

I also laughed and replied casually: "Haha, it's really nothing to look at, let's go." ”

I turned around and was about to leave, when I suddenly saw the young man carrying a box of things into the store, and the owner walking into the store with a few bags of leftover ingredients.

I frowned and felt that something was wrong.

The boss is holding a transparent bag of ingredients in his hand, which looks very familiar, as if it is the quick-frozen chicken nuggets used in the fried chicken restaurants of Nanshi and Renmin Street.

"Isn't Baiyun Food Company not delivering goods to the city? I have to go to the cold storage to get the goods myself, and someone in this house actually delivers the goods? "I'm a little curious about that.

"What did you say?" Officer Wang stood beside me and heard me mutter, but didn't hear what I was saying.

I made up my mind and greeted Officer Wang: "Let's go, let's go to the fried chicken restaurant." ”

Officer Wang didn't know why, but he and I walked towards the fried chicken restaurant.

After the young man finished unloading, he saw me and Officer Wang walking towards him, and a hint of panic suddenly flashed in his eyes.

He didn't make any eye contact with us, hurriedly got into the car, started the car and left.

I also felt a little inexplicable, out of the professional habit of a criminal policeman, I subconsciously wrote down his license plate number, and then walked into the fried chicken restaurant.

"What are you two buying?" The boss asked enthusiastically when he saw the business.

"Police." I showed my police ID.

The boss froze and froze where he was.

"Where did you get all these frozen chicken nuggets?"
