"You just said that the deceased is the missing schoolgirl?" Lei Baoquan began to inquire about the whole thing.

"That's right, just after Xiao Luo's laboratory comparison, it was determined that it was the missing high school girl, who had just contacted their family and said that they would arrive soon." Sun Duo said.

Lei Baoquan was stunned for a while, remembering the mother of the girl he saw on the side of the road in the morning, she was so helpless, and when she heard the news of her daughter's murder at this moment, would she faint because of greater stimulation?

"Tell me about the specifics." Lei Baoquan continued to ask.

The girl's name is Chen Zimeng, 16 years old this year, now in her second year of high school, according to her mother's previous report, on Sunday she went out to look for a classmate, and then disappeared. Her mother approached her classmates and said they hadn't seen her. Sun Duo said.

"What about surveillance on the street?" Lei Baoquan asked.

"Checked, this girl went to a barber shop after coming out of the house, but she came out quickly, and then turned into a small alley, and then ......" Sun Duo shook his head, indicating that he didn't know later.

"Gone?" Lei Baoquan was also puzzled.

"We went to the barber shop and asked, and the people in the shop said that Chen Zimeng wanted to do her hair, but there were too many customers waiting in the shop at that time, so Chen Zimeng left. The rest of the people don't know. Sun Duo explained.

"Where?" Lei Baoquan asked again.

"It's not far from the place where the crime occurred, but it takes half an hour to walk, because it's an old area, so only the main road has surveillance, and it's ...... I can't shoot it. Sun Duo replied.

Lei Baoquan nodded thoughtfully: "It seems that the murderer understands the terrain there and deliberately avoids the surveillance. Have anyone who lives nearby investigated? ”

Sun Duo nodded: "Our people have been there, especially the alley that Chen Zimeng entered, most of the people living there are migrant workers, and most of them are outsiders. It's a mixed bag, and we're investigating them one by one. ”

"Well, that's good, since she disappeared in that alley at the time, it must have something to do with the people inside, and it is impossible for her to disappear out of thin air, right?" Lei Baoquan said.

"That's what I thought, too. So now they are also asking Xiaoliang to hurry up and investigate. Sun Duo said.

While the two were talking, Li Bai walked back from outside, his face was still sticky with water, and he had obviously just washed his face.

"Better, huh? This meal was eaten for nothing, right? Lei Baoquan saw that Li Bai was not in a high mood, and said deliberately.

Li Bai rubbed his face and said, "I didn't throw up, I just went out to wash my face and relieved myself." ”

"Oh, that's amazing." Lei Baoquan nodded matter-of-factly. Then he pointed to the corner of Li Bai's clothes and said, "Remember to wipe it clean after vomiting." ”

Li Bai looked down and hurriedly cleaned up.

Sun Duo smiled silently, and then said to Luo Yiyang, "How is it?" ”

"According to the results of the previous examination, I have just confirmed that the deceased should have been injected with drugs and caused a coma, and then ...... on his head" Luo Yiyang made a cutting gesture.

In other words, the murderer injected the victim with drugs first. After leaving him unconscious, he was transferred to the scene of the crime? Sun Duo said.

"That's right. She has a tube curareine, which is an alkaloid and a powerful anesthetic, which contains toxicity and relaxes muscles and slows down heart rate in a short period of time. If the dose is high, it can also cause diaphragm paralysis and respiratory arrest. Luo Yiyang said.

Li Bai listened to the clouds next to him and said, "It seems to be very professional." ”

"It's really professional, it's a clinical drug. It is mostly used in surgery, the effect is remarkable, but it is easy to have problems, so the dosage must be accurate, otherwise the patient's life will be in danger. Luo Yiyang said.

"The dead ......," Sun Duo looked at the corpse.

Luo Yiyang understood what he meant, shook his head and said, "Although she has this ingredient in her body, it is not a fatal cause, her fatal injury is still a wound on her head." It was supposed to be a craniotomy performed by the killer after anesthetizing it. ”

"Where can I get this anesthetic?" Lei Baoquan asked.

"You can't get it anywhere except in hospitals, unless there's someone on the black market who sells it, but it's almost none." Luo Yiyang said with certainty.

Li Bai thought for a while, as if he had determined the target, and said: "According to what you say, in addition to having this kind of thing, the murderer can also accurately control the dose, he should be a very professional person, is it a doctor?" ”

"It's very likely, you look at his murder method, this kind of surgery similar to craniotomy, it shouldn't be easy for ordinary people to do." Sun Duo also speculated that the murderer's profession might be a doctor.

"What do you think?" Lei Baoquan did not make a conclusion, and asked Luo Yiyang again, he felt that the judgment obtained by only looking at the surface might be 50% wrong, and at this time, it was even more necessary to get the advice of professionals.

Luo Yiyang saw Lei Baoquan asking himself, thought about it, and said: "If you look at the use of anesthetics alone, I agree that the murderer may be a professional person, at least in the use of drugs, he is an extremely skilled person." However, judging from the wound on the deceased's head, it is not quite like it. ”

"Why?" Sun Duo felt strange when he heard it.

"At first glance, the nature of this wound is very similar to the kind of craniotomy done in the hospital, but if we do research, we will know that the craniotomy is completely different from this, and it is impossible to cut the whole head, in that case, it is not surgery, it is simply slaughtering." Luo Yiyang said, "And judging from the wound, the tools used by the murderer are not the professional tools used in the operation." ”

"What's that?" Li Bai asked.

Luo Yiyang paused for a moment and said lightly: "It may be a sharp weapon similar to a machete." ”

"Huh?" Li Bai and Sun Duo were stunned for a moment, and the scene of a person holding a machete and slashing at the deceased's head immediately appeared in their minds.

"But......" Luo Yiyang immediately seemed to have something to say.

"But what?" Lei Baoquan asked.

"But this murderer seems to have a little bit of skill." Luo Yiyang said a little tangled.

"What do you mean? Is it professional or unprofessional? Sun Duo was a little stunned when he heard it.

Luo Yiyang pointed to the wound on the corpse's head and said: "The technique I am talking about is not the technique of surgery, the method used by the murderer is indeed not technical, just simply splitting the head with a knife, but the strength and technique used by the murderer can almost be called perfect." Because according to the normal reaction, if you take a knife and slash at the opponent's head, if the force is small, it will definitely not be this effect, and if the force is too large, the blood will definitely spray everywhere, and the brain inside will definitely be destroyed. But you see, the deceased is almost intact inside, except for the skull being split, which is a really rare chance. ”

"Rare? Why do you still seem to admire this meaning? Li Bai looked at him and said.

Luo Yiyang smiled embarrassedly and said, "If you put aside the identity of the murderer, I am indeed very surprised and admired by his method that almost no one has done, after all, I am also a professional in this area." (To be continued.) )
