Chapter 376

Chen Shi and Lin Dongxue explored the neighborhood, but they did not find the trace of turning over the wall. They also copied the monitoring video of the surrounding shops.

After the police had gone back, the two men drove back. At that time, the preliminary autopsy report had come out. The dead man had been killed by a double-edged weapon running through the main artery, forming a blood gas embolus. Alcohol was detected in his blood. The blood glucose index showed that he had just eaten.

In addition, γ - hydroxybutyric acid, commonly known as "g water", "amnesia water" and "obedient water", was found in the car. It is a kind of spiritual medicine, often used for adultery.

A cup of milk tea overturned in the car also has the same drug composition. There is saliva on the milk tea straw that has not been identified. It is suspected that it was the killer who drank it. Judging from the amount and concentration of liquid left in the cup, the killer took at least 5mg of this drug.

Lin Qiupu said: "it seems that the murderer asked the dead to meet, but the dead was in a bad mood and put medicine in the drink, so she would rashly commit the crime, and did not put Hawthorn in the mouth of the dead."

Another police officer said: "the dead have been raped. It should be a common practice to have this kind of Medicine on the car."

"It seems that the killer was careless and left us a lot of clues. From this guide stick, she should be blind Check manufacturers and sellers. " Seeing the truth, Lin Qiupu said nothing and asked, "what do you think?"

"Is amnesia water aphrodisiac?" He asked.

"No, it's just delirious, but in terms of the dose taken by the killer, she should still be able to move away from the scene of the crime," Peng said

"I have only one idea. If the murderer can get great benefits from killing, how does she know about it? She must have killed someone before, purely by accident or self-defense. Tomorrow, Dongxue and I will go to find the old case to see if there are qualified people."

"I don't quite agree with you about the great benefits of killing, but I think it's a certainty that the murderer is blind." "Today, I visited the friends of the top three dead people. One of song Jicheng's friends said that before his death, song Jicheng disclosed that he had a blind girl and said he intended to meet her. The meeting time was basically the same as the time when he was killed," Lin said

"I think she must be good-looking." Chen Shi said.

"Don't you have any more suggestive opinions?"

"There is another one. The ophthalmology department doesn't need to check any more. Judging from the murderer's actions, she is a" senior "blind person. Such a blind person usually doesn't go to see a doctor. Blind people can be found. The blind people in the city should know each other. "

"But there are a lot of them. I didn't know that there are so many blind people in Long'an."

Chen Shi shrugs. "I'm home."

The investigation of the case is in full swing. In recent days, each of the task force has met more than ten blind people on average. Chen Shihe and Lin Dongxue have also visited some blind people who have had the case, but none of them meet the requirements.

There is no such thing. When Chen Shi sees it, he has a voice saying "it is her".

On the afternoon of June 15, Chen Shi and Lin Dongxue went to see a blind man. She had been raped and self-defense, and hurt the rapist. However, when they saw her, she was a 17 meter fat girl, which was not consistent with the characteristics of the murderer.

Come to all come, Lin Dongxue or the certificate light out, said: "are you Kangli?"

"Yes, you are police? What can I do for you? Did the rapist catch me two years ago? "

"We're working on a case. Where were you on the night of June 13?"

"I was in the store that day, and the manager could testify."

"The blind massage in the alley below?"

"Yes, what case are you looking for? Was that rapist killed in that year?"

Chen Shi added, "why do you ask?"

"You probably don't know. That guy picked on the blind. It's terrible. When I was defending myself, I bit his ear. The police found his identity through DNA. It seems that his name is Luo Shiyu, that's the name. "

"Has he ever done anything else? How do you know he's only looking for blind people? "

"Because some of my friends have been hurt, this guy has been on the run, and it has stopped for a while, so I think that since you came to me, it's mostly for this matter Is he dead? "

"It's not easy to reveal now."

"Let me know when it's convenient for you to disclose. Because of that, I'm afraid to go out now."

"OK Who do you know about the people he raped? "

Chen Shi wrote down several names and said goodbye to Kang Li. He asked Lin Dongxue to call the local police station and ask about the guy's whereabouts. Lin Dongxue talked a few words and covered her mobile phone and said, "they said that this man has been missing for a year."

"Where does he live?"

"CaoShi street, Guyi lane."

"Go and have a look."

"Ah? Do you suspect that the rapist was killed by the murderer? "

"I'm also bumping around now, so I might as well go and have a look."

After getting on the bus, Lin Dongxue asked, "what did you say before that the murderer would get great benefits from killing people

"What's the good for a blind person to take risks?"

"It can't be eye blindness, can it?"

"That's what I think."

"Are you teasing me? Kill people and you'll see? How is this possible? "

"That day when I saw the surveillance, I came up with this idea. I also thought it was ridiculous, so I asked Miss Gu We're in touch on the cell phone. "

"What did she say?"

"She said that it is possible that psychogenic blindness, also known as somatic conversion disorder, is caused by the huge mental stimulation of the party concerned, which leads to the loss of some physical abilities. But unlike the real blindness, her eyes can still receive visual signals, but they do not realize it, just like a normal display and a normal computer Host, there's something wrong with the wiring between them. "

"I don't quite understand!"

"In a word, her eyes are good, but she doesn't know that she can see. She thinks that she is blind in her heart. Miss Gu thinks that under the strong stimulation of killing, she is likely to regain her vision for a short time. For a blind person, she can see the colorful world at once, and this "reward" is better than everything, so she will kill again and again. "

"Is there such a motive?" Lin Dongxue shivered for a moment. "Are you sure?"

"It's just a hypothesis. After all, the probability of this kind of thing is very low, and it belongs to the category of medical miracle We start from the high probability events, from the murderer's time of committing the crime and the fact that she can come out alone to meet men, she has quite free time and is more likely to live alone. In these two days, we have not less checked the blind school, blind massage shop, blind car repair shop and other places, looking for blind people who live together. If she is a blind woman who lives alone, has good looks and is young, it is also possible that she will be targeted by rapists who choose blind people to start with. Anyway, try her luck! "

Lin Dongxue smiled. "There are enough trial and error times, and the truth will pop out."
