"So have you noticed that Xiao Liu and Xiao Fang went to the bathroom in the middle of the night."

She blinked, thought for a moment, and nodded, "Yes, I heard you." ”

"So did the bed shake happen before or after they went?"

"Hmm... It seems that after they went, I heard Xiao Liu call Xiao Fang's name in the middle of the night, and then soon after, I felt Xiao Wen shaking. ”

If that's the case, then the time when Xiaowen was killed is probably the time period when Xiao Liu and Xiao Fang went to the bathroom, well, at least we have a time frame.

"May I ask if you heard Xiaowen's movement on the way to the bathroom, that is, the sound of her turning over." I looked at Xiao Fang with an impatient look and asked.

"Roll over? Hmph, I'm angry when you talk about this, she often tosses and turns in her sleep, but it's annoying. ”

"Then you heard it, didn't you?"

"Didn't I say, she just kept tossing and turning like that when she slept, I didn't see her settle down, didn't she just a few mosquitoes? As for being noisy all the time? ”

I asked Xiao Liu the same question: "May I ask if you heard Xiao Xiaowen's movement on the way to the bathroom." ”

"Hmm.... It seems that there is. ”

"Like? Can it be accurate? ”

"Well, yes, I remember when I passed by Xiaowen's bed, I felt the bed shaking."

"Don't you see someone standing in front of her bedside?"

"No... No, how could it be... Uncle policeman, don't scare me. ”

"I'm sorry." I shook my head with a smile, and I thought it was a silly question, how could she not see a person standing in front of her.

"And did you hear a violent shaking sound on the little bed after that?"

"Nope." Xiao Fang replied.

"Nope." The same statement came out of Xiao Liu's mouth.

Although the case is still filled with white fog, at least the original purpose has been achieved, and it can be confirmed that the time of Xiaowen's death is during the time when Xiao Liu and Xiaofang got up to go to the bathroom, and Xiaowen was still alive before that, because Xiao Liu and Xiaofang both heard the sound of Xiaowen turning over, and whether either of them lied or not, they could confirm that they did not hear the sound of Xiaowen being killed after them, so the time frame of the crime was determined.

I was standing in a dormitory with a few detectives, thinking about talking to each other.

"At present, Xiaoli's suspicion should be ruled out." A detective said.

"Well, the most likely perpetrator at the moment is Xiao Liu and Xiao Fang who went to the bathroom, because Xiaowen was still alive before they went to the bathroom, and then they went back to bed and didn't sleep, and they never heard Xiaowen make a movement again, which means that one of the two of them killed Xiaowen between going to the bathroom."

"May I ask if you go to the bathroom first or Xiao Liu first." I looked firmly into Xiao Liu's eyes, hoping to see something in her flustered eyes.

"I.... I'm first, oh no, no, no, it's her first, she's on first. ”

"Was she still outside when you went to the bathroom after that?"

"Of course it is, but where else can I go? She said she would always be out with me. ”

"I mean, can you confirm she's out there? In other words, have you been talking to her all the time? ”

"There was no conversation.... I didn't have the heart to chat so much in such a dark environment, but I called her on the way, and she didn't answer at first, but after I called a few times, she answered, and then I mistook her for a ghost...."

I looked at the detective next to me for a moment, reached out and touched my chin and narrowed my eyes.

"May I ask if Xiao Liu has been standing outside when you go to the bathroom?" I looked at Xiao Fang

"Of course, she kept urging me to hurry up, urging me to be annoyed to death."

"Then why didn't you respond when she called you at first when you were waiting for her."

"Please, she's been shocked, I'm already quite tired, I really don't want to pay attention to her." Xiao Fang frowned and looked at us with a bored expression.

"May I ask how your relationship with Xiaowen is usually." At this time, the three of them had already gathered together, and I asked questions in unison.

"It's all good, everyone is roommates, shouldn't they all love each other?" Xiao Fang replied.

"But....." Xiao Liu looked a little distracted.

"But what, isn't that what it is? What is it. ”

"Didn't she just quarrel with you a few days ago? Because she kept looking for the boy you liked after class, you couldn't see that she had a big fight with her when she went back to the dormitory, and if we hadn't pulled it, you would have started fighting......"

"You're fucking lacking in heart, aren't you, we're going to unite at this time, why do you talk about everything?"

"Is that so?" I raised my brow.

"Well, yes, I did have a fight with her before, and I did hate her, so what? Does that mean I want to kill her? Does that mean that the person who killed her was me? ”

"I can't." I shook my head.

"And don't talk about me, didn't you borrow money from her yourself, but she never paid it back, didn't you swear that she would kill her if she didn't pay back?" Xiao Fang's face showed a hideous look.

"I... I was joking. Xiao Liu was stunned.

"Come less, I think it's because she hasn't paid you back and ignored your warnings, that's why you killed her."

"You talk nonsense!"

"Stop arguing, stop arguing." Xiaoli persuaded worriedly.

For a while, the room was in a mess, I turned my back and felt like a slurry, and I had a vague premonition that the murderer must have come prepared, and everything at the moment was still in her expectations, and we were still passive.

Since we couldn't determine who the murderer was, we had no reason to leave them behind, after the fright, they re-engaged in the class, we cleaned up the scene, and prepared to leave, but before leaving, I suddenly noticed that above Xiao Liu's bedside, there was a small recording box, I opened the recording, and found that there was no sound except for some English words, it seemed that there was originally, but it was deleted.

We soon returned to the bureau, and the autopsy results showed that the cause of death was indeed caused by the use of rat poison, and I discussed the case with the detectives overnight.

"The deceased Xiaowen, 17 years old this year, was found dead in bed by his roommate at 6 o'clock this morning, the cause of death was taking highly toxic rat poison, we found traces of rat poison in the corner of the bedroom, but to reach the level of poisoning the deceased, it must be prepared in advance."

"After questioning, we got testimony from a security guard, who said that during the night patrol, he saw the deceased on the balcony and saw Xiao Fang supporting the frightened Xiao Liu, so he could prove that this was correct,"

"Through questioning the students in the dormitory next door, we learned that because the bathroom door where the deceased was located on the night of the crime was broken and could not be opened, the deceased Xiaowen had gone to their dormitory to wash her hair, and washing her hair was very troublesome for girls, if the deceased had been ready to commit suicide, it was impossible to wash her hair, and it could be confirmed that the deceased was the victim."

"Will there be outsiders committing crimes?" A detective asked.

"I've thought about it, but this possibility is basically zero, let's not talk about the previous testimony, just say that the bedroom door, once opened, will make a very loud noise."

"Then the most suspicious person at the moment should be her roommate Xiaofang, because Xiao Liu said that when she was originally called Xiaofang, Xiaofang did not answer, indicating that she should have left the door at that time and walked into the bedroom to kill the deceased Xiaowen." A criminal police officer said.

"Well, besides, she still has a motive, although this contradiction is not a blood feud, but minors are too young after all, their thinking is too impulsive, and it is very likely that they will choose to kill on impulse."

"But Xiao Liu also has a motive."

"But when Xiaofang was in the bathroom, she was always talking to her outside the door."

"No, it's possible, she's not outside the door." I spoke suddenly.

"What?" The rest of the people looked at me in surprise, and a sharp light flashed in my eyes.
