"The perpetrator is quite familiar with the campus environment," Qi Yuan couldn't help but say: "Whether it's in the dormitory, break the camera before committing the crime, or ...... here."

Xun Mu thought thoughtfully, waved his hand to ask Qi Yuan not to speak first, and then asked the security guard: "The surveillance camera in the dormitory is broken, haven't you noticed it?" ”

"I don't know, I'm not in charge of monitoring this, but I only help occasionally take a look." The security guard quickly shook his head, instinctively brushing aside his responsibilities, and after a while, he hesitantly explained in an uncertain tone: "However, it shouldn't be strange."

The cameras in the school are some years old, and they will break a few from time to time, and there are many dead ends, and more often they are bluffing, and they don't use it at all if something really happens.

It's really going to be broken, I guess it's just a registration, and go back to report to the logistics maintenance or change one, but whether it will be replaced or not, and when it will be changed, I can't say for sure, and we don't count. ”

Xun Mu listened, a little helpless.

Without the help of surveillance, this case is covered with a layer of mystery, and it will not be easy to detect.

Of course, the criminal police are by no means just solving crimes through surveillance.

For example, Qi Yuan was vaguely a little excited at this moment, and he was a little eager to try. Finally figured out his thoughts, he was quite interested in this case.

While talking, the ambulance finally arrived at the school.

As soon as the medical staff got out of the car, the female counselor waved her hand: "Leave me alone, I'm not seriously injured, and I'll be fine for a while." I heard that a student didn't die and fainted, so you should go to the dormitory building and pick up the child in the car, and then take me with you when you come back. ”

"It's a waste of time to stop twice," the doctor said in a deep voice, "You better just get on the bus with us, let's go to the dormitory building to pick up the students, and then go straight away." ”

The counselor hesitated for a while, nodded, stood up, and let the nurse help him into the car, even the stretcher was useless, obviously the injury was really not serious.

After they left, the few people who had gathered around dispersed. Before leaving, Xun Mu instructed them to pay more attention to safety, try to be a partner, and not act alone, and asked the security guards to help seal off the campus.

Then he looked at Qi Yuan and said, "Xiao Qi, tell me, what do you think." ”

"I think we should start the investigation with the motives of the perpetrators." Qi Yuan immediately said: "Regardless of the modus operandi for the time being, strip off the cloak of the mysterious and supernatural, and treat this case as an ordinary murder case - of course, the number of victims is really a little more......

I think doing this will help you find the right direction quickly. As for the murderer's modus operandi, according to Brother Song's consistent meaning, as long as someone is caught, won't the truth be revealed? There's really no need for us to let the murderer lead the way and play some game of guessing and decryption with him. ”

"Oh?" Xun Mu glanced at him in some surprise, and then nodded again and again: "Yes, I finally realized this, and I have made progress." Go on. ”

Qi Yuan scratched his head a little embarrassed, and then immediately continued: "To confirm the murderer's motive, I think the first thing to do is to find the common ground of all the victims, including the counselor.

Of course, there is also a more general speculation that the murderer should have killed in retaliation, but whether it was a personal contradiction or emotional entanglement, or something else, it is difficult to say now.

Moreover, the suspect has several characteristics, which can now also be determined. First of all, his head is still relatively flexible and bright, otherwise he wouldn't be able to deploy this game, but at the same time, he may still be a little second......

On the other hand, he should be quite familiar with the school environment, and he may be a student of this school, so I thought that he might be able to use this as a direction to collect clues at the beginning of the investigation. ”

"Almost, the focus of the initial work is in place." Xun Mu nodded.

After hesitating for a while, Qi Yuan continued: "In addition, Team Xun, I personally think that public opinion should also pay more attention.

The campus case, coupled with the supernatural color of this case, both of them are quite topical, and it is easy to cause viral spread, and there are all kinds of chasing after the wind and shadows, specious analysis and speculation and false rumors of the people who eat melons, and the impact may be very bad, so we have to take precautions. ”

Xun Mu was even more surprised, obviously he didn't expect Qi Yuan to be able to take care of this aspect, and at the same time nodded and said, "Don't worry, we have taken these into account, and there will be people to keep an eye on it early in the morning." ”

Qi Yuan snorted, when he said this, of course, the fundamental purpose was not to remind or suggest anything, it was just a performance, to let Xun Mu know that he was still more comprehensive in considering the problem, and that's it.

However, he always felt that Xun Mu's attitude seemed to be a little perfunctory. He didn't care either, this case was indeed enough of a headache, and the previous case also restrained Xun Mu's energy, which he understood.

The reason why he was in a hurry to perform, a large part of which was also to share the worries of Xun Mu and Su Ping.

……

When the police from the nearby police station and the District Criminal Investigation Brigade arrived at the school, Xun Mu arranged tasks for them, and then took Qi Yuan back to the dormitory building.

Chai Ningning's preliminary on-site investigation came out, and she identified at least four suspects — two of whom entered the room and scared the victims away, or forced them away, spilled a large amount of blood in the dormitory building, and left a severed finger with an unknown motive.

At the same time, at least two other people, from the bottom up, further forced the five girls onto the rooftop, and eventually killed them on the rooftop, and then left the scene.

On the other hand, Yan Zhongxin also completed a preliminary autopsy and determined that the murder weapon was a single-edged sharp weapon with a certain arc with a length of more than 15 centimeters and a width of 2.5 to 3.5 centimeters.

The murderer did not seem to have any experience in killing, and he was more nervous when he committed the crime, only slashing and stabbing in an orderly manner, and finally killed four people and left.

Moreover, among the five girls, three of them left dandruff tissue between their fingernails, which was probably scratched from the suspect's body during the resistance, which is important evidence, and Yan Zhongxin extracted and preserved it.

"That's the basic situation, removing the supernatural cloak that pretends to be mysterious, this case should not be difficult to solve, as long as the target is locked, it is easy to further confirm or deny their criminal suspicions." Su Ping said, and asked Fang Chang again: "After you visited around, did you suspect that the target had entered the line of sight?" ”

"Not yet." Fang Chang shook his head, and then said: "But I found another suspicious point, the girl who was lucky enough to escape the catastrophe seems to have been in the boiling water room for a long time, and several girls who have been to the boiling water room on the same floor have said that they have seen her, and the time span is more than an hour." ”

"Oh?"
