Seeing that he couldn't ask for any useful information, Xiao Ning stood up and walked out of the sentry box.

Yin Zetai did not forget to tell the security guard, "If there is any suspicious situation, notify us immediately." ”

"Okay, I'll let you know."

Xiao Ning strode ahead, and soon came to the pool again.

At this time, the corpse was no longer visible in the muddy water, and there were many things that had been salvaged from it on the ground. There are watches, there are necklaces and so on.

Xiao Ning squatted down and put on his gloves to fiddle with the contents inside.

A police officer in charge of salvage straightened up and said, "Captain Xiao, no useful evidence has been found so far, it should all be the things on the deceased." ”

Xiao Ning didn't speak, but he didn't agree with him in his heart. There may be dead people, but there may also be murderers who have fallen.

He stood up, "Anyway, pack them all up and go to the lab one by one." ”

After speaking, he took Yin Zetai into the main teaching building again.

All the teachers gathered in a conference room, waiting to be questioned.

Xiao Ning came to an office opposite, and Yin Zetai walked out and called a teacher over.

"Hello." Xiao Ning spoke first, "Please take a seat, I just ask you some things routinely, don't be nervous." ”

"Okay." The young female teacher sat across from her, "Officer, just ask, I'll tell you everything you know." ”

"Have any students gone missing in the school lately?"

"Nope." The female teacher replied, "If this happens, the school will definitely report to the police and notify the family." ”

Xiao Ning nodded and continued to ask, "Then are there any students who suddenly don't come to class, and their parents call and say that they want to transfer or suspend school?" Or take an extended sick leave? ”

Fourteen corpses, and nine others that could not be identified, could not be assured that there were no students among them.

The female teacher pondered for a moment, "There have been a few students who suddenly stopped coming to class, but the parents all said that they would take a day of sick leave, and they would come the next day. There has been no transfer or suspension, and our school is already the best key high school in the city. There was one of the long sick days last month, but the student was in the hospital, I was in charge of the class, I visited a few days ago, and it was true that he was very sick and needed surgery. ”

Yin Zetai, who was next to him, was in charge of recording what the female teacher said and signaling her to leave.

The next few teachers answered the same as her, and as for the strange thing, it didn't happen either.

It can be said that no useful information was found in this inquiry.

Yin Zetai closed his notebook and voice recorder, "Boss, how can this be checked, there is no connection between the deceased, and nothing strange happened to the school that was the scene of the dumping of the body." ”

Xiao Ning rubbed his temples, "Have you checked the surveillance in the school?" ”

"I have checked, there are cameras in the main teaching building and student dormitory and canteen, as for the back of the experimental building, there is not a single probe, we have called up the surveillance video of the last three months, and we are still checking, and the results may not be released until tomorrow."

The office was silent, only the sound of breathing could be heard clearly.

After a long time, Xiao Ning spoke, "Let's go, the rest of the things will wait for the autopsy reports of the rest of the corpses." ”

On this day, all the people in the criminal police brigade worked overtime, the phone calls were constant, and the information was constantly called out.

Xiao Ning turned off the lights in his office and walked in the bright corridor, his mind full of those corpses.

Back at home, he lay on the bed and looked at the ceiling.

Tonight, let's hope to dream.

He closed his eyes.

The belly of the fish rose to the sky, the morning sun rose, and the city regained its vitality.

When Xiao Ning opened his eyes, the first thing he did was to pick up his phone.

It was half past six in the morning, and that night, he didn't dream.

After getting dressed and hurriedly settling breakfast, he came to the criminal police brigade.

At this time, it was not yet seven o'clock, and almost all the police officers had already come to work, and there may be some people who worked overtime until midnight and fell asleep here.

Xiao Ning walked into the office, and Li Ke and Xu Xingteng actually arrived so early.

The two of them were discussing the case while having breakfast, and when they saw him come in, Xu Xingteng said, "Boss, have you eaten?" ”

Xiao Ning nodded, "I've eaten it." ”

Li Ke swallowed the fritters in his mouth, "Boss, I thought about it for a long time last night, and I found a few suspicious points. ”

"Say."

He looked at Xiao Ning, who was already sitting in the chair, and wiped his mouth, "You said that these people have no intersection, why were they killed and thrown in one place?" ”

Xiao Ning raised his eyebrows and continued to listen.

"Also, why did the murderer choose them?"

Li Ke said a lot in a row, and even Xu Xingteng next to him couldn't listen to it anymore, "If we knew these questions, we would have solved the case a long time ago, then we have to ask the murderer." What kind of suspicion is this, I don't think you woke up yet, right? ”

Xiao Ning shook his head, "Li Ke did a good job, he pointed out the direction we need to investigate, as long as these questions are investigated clearly, the answers will be clear." ”

At ten o'clock in the morning, the medical examiner's autopsy report finally came out.

Zhang Yu handed the document to Xiao Ning, "Because there are too many corpses, now there is only one forensic doctor and two assistants, I can only dissect one first, and I am afraid it will take some time for the rest." ”

One is enough.

Xiao Ning opened the file.

The cause of death of the deceased was mechanical asphyxiation, and obvious wounds were found on his neck, with cotton wool left on the surface of the wounds, and the murder weapon could be judged to be a white hemp rope, the thickness of which was about one centimeter in diameter.

The deceased's blood was found to contain a surviving ingredient of the drug, a prescription drug that could be used in a coma when mixed with another drug, which could only be purchased with a certificate from a hospital and was rarely seen in ordinary pharmacies.

Later, an incision of about 20 centimeters was found in the deceased's stomach, which was very flat and could be judged to have used an object similar to a scalpel.

The incision was made in the chest cavity, and the position was very accurate, and the internal organs were missing, and the heart and kidneys were missing.

After reading the document, Xiao Ning raised his head and stared at Zhang Yu, "The murderer is likely to be a doctor?" ”

Zhang Yu nodded, "That's right, because the incision location is the place where surgical incisions are usually made, and the heart can be accurately taken out there." If you don't understand, you won't be there. Although there is no way to determine that the murderer is a doctor, at least, the murderer understands medical things and may even have clinical experience. ”

Xiao Ning continued to ask, "Can the knife that cuts the part be judged to be a scalpel?" ”

"Yes, if it weren't for a scalpel, it wouldn't have left such a smooth wound."
