Still in the analysis room of the police station, the boy's body has been transported here, because the specific cause of the boy's death is not known, so they can only ask Li Qiusheng to solve this problem for them, he is still like that, with a big beer belly, it seems that he has not drunk a few tons of beer recently, otherwise how could his stomach become like this, like he is seven or eight months pregnant.

"I can't accurately measure his red blood cell count or hematocrit before he died, but I estimate that the child had only a quarter of his blood left while drifting. Li Qiusheng handed over the laboratory data in his hand to Wang Lei. He himself came to the other side, looked at the corpse and said.

"How many milliliters did you lose?" asked Wang Lei.

"Nearly 3,400 milliliters or more. Li Qiusheng said without exaggeration.

"Is it possible that he has hemophilia?" asked Han Weixue on the side.

"No, I did. No drugs were detected in his body. Han Weixue looked at Wang Lei a little incredulously, how could a normal person lose so much blood at once.

"And what's the problem with the wound on his neck?" asked Wang Lei.

"Maybe it's a vampire, or someone who wants to be a vampire, or someone who gets blood quickly, it's about the same size as an IV needle, I hope it's an IV. Li Qiusheng turned the child's head to the side, pointed to the wound on his neck and said.

"How could this kid have an IV needle stuck in his neck, but he ended up falling into the river?" asked Han Yuxue puzzled.

"I often saw this kind of case in the late 80s, when all kinds of demon cults were rampant, but recently they have been rare, maybe they want to make a comeback. Li Qiusheng said recalled.

"What was the cause of his death?" asked Wang Lei on the side.

"He drowned. But I guess he drowned because he lost so much blood and was too weak. ”

"Then is this an accident or a homicide?" Wang Lei was a little confused, what was this, if it was an accident, then this case would not belong to them.

"The injection needle accidentally ran to the top of the neck. Han Weixue looked at Wang Lei speechlessly.

On the computer in Wang Lei's office, he quickly found all the information about this child, his photo appeared on the computer screen, with a smile on his childish face, he was wearing a dark old shirt, which looked a little tacky, but the trendy hairstyle and clothes formed a sharp contrast, it seems that this dress was worn for photography.

"The deceased was found based on the fingerprints of the deceased. Han Weixue said to Wang Lei behind her. Wang Lei seemed to be looking for the previous file, and after hearing Han Weixue's words, he walked over.

"His name is Cai Ming, 18 years old. ”

"At a young age, he even had a criminal record. Wang Lei looked at the screen and said.

"Stealing, robbing, and illegal entry, it seems that they are not from our port city, they are from Yangcheng. Han Weixue looked at the child's file and read that although the child has some inferiority, he is still a child after all, and it is not to the point of causing death.

"I found out that his last mailing address was in the city, so let's take a look at the map. Wang Lei brought a map from his desk.

"We found the body at the bottom of the river, and the upstream river covers a restricted area of several kilometers, which belongs to the green protection area, and it is impossible to tell where he came down the river. Wang Lei pointed to the map and said.

"You can start with his last mailing address to see if anyone knows him there. Han Weixue thought for a while and said, after all, there is only this information now, and the area of those few kilometers is too big, and it is undoubtedly looking for a needle in a haystack.

"Okay, print a few photos and bring them along. "The two men set off.

Han Weixue soon came to a hotel, which belongs to the kind of relatively low-grade rented for the homeless, so the general rent is also very low, Han Weixue and they found the owner of the hotel and opened Cai Ming's room for them. The room was very small, Han Weixue and they searched around, but they didn't find any useful clues, the boy didn't have anything valuable at all, maybe the valuable thing was his clothes, and it was not easy for these migrant workers to live.

"He took this room out about six months ago. The boss said.

"When will he come back?" asked Han Weixue.

"He usually comes back late every day, but I haven't seen him for at least a month. ”

"Did he bring any companions?" asked Wang Lei.

"I never noticed that a lot of street thugs rent rooms with us, but as long as they pay their rent on time, I never ask about anything else. ”

"Thank you. Han Weixue said, then turned around and walked towards the door.

"You're welcome. "The boss closed the door.

When Han Weixue walked to the door, the door was pushed open from the outside, and a child walked in, carrying a backpack on his back, it seemed that he was also a resident here, and he and Han Weixue walked by.

"Han Weixue, wait a minute. Wang Lei stopped Han Weixue, he looked at the child, as if he had found something.

"The necklace around your neck is a shell necklace, right?" Wang Lei said to the child.

"Yes, what's wrong?" The child turned around and looked at Han Weixue and Wang Lei with a blank expression, his eyes full of vigilance.

"Have you seen this kid around here?" Han Weixue took out a photo of Cai Ming from his pocket.

"Are you police officers?" the child didn't answer their question at all, but was attentive to who they were.

"Don't worry, he didn't do anything. ”

"Have you seen him? That's important. Han Weixue put the photo back.

"I've seen him, but I don't know him. ”

"Where did you buy your necklace?"

"It's a stall not far down this street. ”

"Where exactly?" asked Han Weixue eagerly, this might be their only clue.

But when the child saw Han Weixue like this, he stopped talking, Han Weixue knew that he was in too much of a hurry, and this child didn't seem to have a good impression of the police.

"Listen, he's dead, we just want to find out what happened to him. Han Weixue said sincerely.

The child looked at Han Weixue, and then at Wang Lei, not wanting to lie to him, so he said: "She set up a stall opposite the square, and she usually comes out at five o'clock in the afternoon, her name is Zheng Qian." ”

Every afternoon, there will be a lot of people gathered in this park, some come here to exercise, some come here to relax, and there are also many homeless people and homeless people who regard this place as their home, and the park chairs as beds, which is to use the earth as a bed and the sky as a quilt. There is a stall here, and there are a lot of people around it, and it seems that the business is not bad.

Han Weixue and Wang Lei walked in front of the carpet, which was made of various shells, and it seemed that the workmanship was still very good.

"The necklace is good, how can you sell it?" asked Han Weixue.

"I didn't sell them, just for charity. The girl looked up at the two of them, and it seemed that they were law enforcement officers, so she said in a panic, the girl is very delicate, with a high nose bridge and big eyes. But the clothes on the body obviously don't fit very well.,It seems that it's also the kind of homeless.,I don't know if it's because I don't have parents or run away from home.,There must be some reason.,
