Song Zhinuan squatted in place and then looked back at Team Yang, and after thinking about it, he said, "The murderer is a person who understands medicine, and the one who dares to blatantly kill people in the mountains behind the school should not be people outside the school, the murderer is in this school." ”

Because, if you want to enter the back mountain, you must pass through the school gate, and you can go to the back from the inside of the school.

If it's an outsider, the target will be relatively large and easy to catch.

The only people who don't arouse suspicion and are easy to hide are people inside the school.

There will be convenient conditions in all aspects.

Team Yang immediately understood what Song Zhinuan meant, and ordered the team members with a sinking face, "Immediately block the card holy land, and focus on investigating the students and teachers of the medical department." ”

"Yes!"

They acted very neatly and immediately got to work.

There's one more point, though.

After thinking about it, Team Yang looked at Song Zhinuan, and just as he wanted to say something, Song Zhinuan said, "You want to ask me, is there any causal relationship between the deaths of Su Jin and Su Jun, the brother and sister?" ”

This incident is indeed strange, the brother and sister were killed one after another.

Team Yang nodded, "Could this murderer be a person?" ”

"Remember the cause of Su Jin's death? The internal organs were dug up, professional stitching techniques, not leaking, that is to reflect the real psychology of the murderer, distorted, fearless, crazy, although the method of killing Su Jun seems to be rough, in fact, the direction is the same, the murderer has a relatively strong psychology, but, for the crime, his logic is still a little dull, he thinks he is clever to hide from the world, if it is right, it should be the same person, the search range is weak, the murderer is left-handed. ”

Song Zhinuan narrated the whole process unhurriedly.

Team Yang didn't have the slightest suspicion, and immediately ordered someone to do it.

In fact, the interpersonal relationship between Su Jin and Su Jun has been investigated, and the brother and sister do behave perversely, and they usually offend many people, but it is not enough to be involved in the level of killing people and venting their anger.

What is the reason for the murderer?

It's an unknown puzzle.

Su Jun's body was quickly cleaned up, and although the school knew about it, it had been forcibly suppressed by the school.

If it doesn't spread, it will have an even worse impact.

As for Su Jun, he is not a student of the school, what is he doing at the school?

There are still many unsolved mysteries.

The quiet school road, the stone road is very comfortable to step on, and the pine forests on both sides are also a landscape.

One tall and one short stroll here.

Bai Chumo looked up at the high and white sky, and seemed to glance at her, and the corners of his mouth outlined a warm and indifferent arc.

"You just hid something, didn't you?" He asked.

It's not so much an interrogative sentence as a declarative sentence.

Song Zhinuan's eyebrows raised slightly, and he looked up at the smooth and graceful side face of the man next to him, the lines were extremely good-looking, almost delicate to every centimeter.

She was also calm, as if she was talking about someone else's business.

"The brothers and sisters of the Su family have a common characteristic."

"For example?" He looked sideways.

Song Zhinuan squinted, as if sighing, "Both brothers and sisters have had a holiday with me, Su Jin had a quarrel with me half a month ago, because she felt that I stole her limelight and targeted me, and then disappeared, Su Jun's words, the professor also saw it, the last time he tried to kill me with a knife, he didn't succeed, he was arrested and detained at the police station for a few days, and he died on the day he came out, which ...... Is it really a coincidence? ”
