The new guest quickly sat down in front of my eyes, my eyes suddenly lit up, and I secretly had a suspicion in my heart, my eyes glanced at his waist, and sure enough, I saw the handcuffs tied around his waist, and I was shocked that it was another policeman who came.

Bless the policeman for his victory over his enemies in his story, I thought silently in my heart and slowly picked up the pen in my hand.

"Xiaofang, accompany me to the bathroom, I'm scared at night."

"You're such a coward, forget it, I just want to go."

"Xiaofang, are you still there? Xiaofang? ”

"Here, here, hurry up, I'm going to be sleepy."

"Holo ..... Wait a minute. ”

"What's wrong again?"

"Because I suddenly remembered that today is not the weekend, isn't it? You're not... Are you all home? So who are you? ”

My name is Kang Zheng, I am a police officer, and I am the deputy head of the criminal investigation team of the county public security bureau.

This morning, we received a report from a teacher who said that one of her students had committed suicide by poisoning in her dormitory this morning.

We quickly arrived at the school, the murder took place in the girls' dormitory, through the narrow aisle, we passed the onlookers into the dormitory, as soon as I entered the door, I saw the girl lying on the bottom bunk bed, she was pale, foaming at the mouth, and looked lifeless.

The deceased's name is Xiaowen, the process of the case is like this, today is Monday, the year has a routine morning meeting, so the students have to get up early, but the roommates suddenly found that Xiaowen did not get up for a long time, so they thought she was lying in bed, but soon everyone found that no matter how Xiaowen was called, there was no reaction at all, when a roommate put his hand in front of Xiaowen's nose, she screamed in surprise, because she found that Xiaowen was no longer breathing.

Soon they found the teacher, who immediately dialed 120, and the doctor rushed to the scene and confirmed that Xiaowen had died, the cause of death was rat poison, and the preliminary judgment was that the time of death was about 12 to 4 o'clock at night.

There are four people living in a bedroom, namely Xiaofang, Xiaoli, Xiao Liu and the deceased Xiaowen, we asked the other three, Xiaoli said that because the bedroom is close to the mountain, there are many mosquitoes, and there are often rats, so each bedroom is prepared with rat poison, Xiaowen is to take the prepared rat poison to die.

The deceased Xiaowen had a lot of claw marks on her face, according to her upper bunk Xiao Liu, Xiaowen was blood type O, very mosquito-provoking, and her face was often bitten to the point that her body was incomplete, and she often scratched it with her hands, so she had these claw marks.

When asked about the deceased Xiaowen's situation and psychological state before his death, the three roommates expressed regret, they said that Xiaowen's grades were not good, his appearance was not outstanding, and he belonged to a very inconspicuous kind of student at school, mainly because she also had an older brother, her parents died in a mining accident, and the mine owner ran away after the incident, and has not been found yet, and her brother has been fooling around in society and not doing his job, so she has to work and study, while her brother is addicted to gambling and lustful, and often comes to her for money, She couldn't refuse her brother's excessive demands every time. In addition, she has not studied well, and she is very distressed.

Xiaowen often confides in them, she feels very stressed, she says that she feels that she is about to live, they all think that Xiaowen is just talking, but they didn't expect this to happen now.

We also confirmed with the teacher, and the teacher confirmed that this was indeed the case, so she went to Xiaowen to communicate, and she also felt very sorry and heartache for Xiaowen's death.

It seems that it should indeed be a suicide, and I sent the criminal policeman Lao Wu to contact the family of the deceased, because her brother does not have a fixed residence, so it will take time.

Then bring the deceased back to the bureau first, I commanded to go down, but when I walked to the deceased's side, I stopped and stood where I was.

I narrowed my eyes and leaned over the deceased's body, looking at her godless face, and suddenly I froze as my gaze fell on the claw mark on her mouth.

"What's wrong Team Kang, what's the problem?" An interpol officer approached.

"Look at the corners of the deceased's mouth."

"Hmm... It's a claw mark yes, this should be scratched by the deceased himself, because there are a lot of mosquitoes in the dormitory. ”

"But there wasn't a single mosquito-bitten red spot near this claw mark."

"What?"

My pupils shrank, I stood up and looked back at the people in the room, "That's right, this is not a suicide case, the deceased Xiaowen actually died from homicide, and she was killed by one of the three of your roommates!" ”
