Wen Jiajia and Tian Zhuhai went to Tian's house together, Dongfang Tuo secretly followed behind, and accidentally, Tian Zhuhai saw part of his figure, so he immediately hid behind the wall.

Tian Zhuhai's voice was still crying: "Who is the person in the back?" It's weird......"

"I'm afraid, someone is guilty!" Wen Jiajia said out loud coldly.

Tian Zhuhai looked at Wen Jiajia suspiciously.

Dongfang Tuo whispered to himself: "Cut, I think you are amazing." ”

When they arrived at Tian Zhuhai's home, two policemen were also at the scene.

Among the several neighbors who were watching the excitement, Dongfang Tuo looked at the two policemen from a distance, and felt a little familiar: "Huh? Aren't they the black police officers and police officers Zhang who have come to the school? Wen Jiajia is a stupid person, and she will never recognize them. ”

After Wen Jiajia entered the door, she shouted: "Hello uncle and aunt, good black police officer Officer Zhang." ”

Dongfang Tuo was angry helplessly for a few seconds: "Uh......"

Officer Zhang was holding a pen to record something: "So, your daughter, Tian Yan, committed suicide." ”

Tian's father and Tian's mother were in pain: "My poor daughter. If my son hadn't brought the pesticides for the fruit trees to the house, my daughter wouldn't have thought of killing herself by drinking pesticides. What a useless son......"

Tian Zhuhai knelt down with a puff: "I, today's pesticide ran out, and I didn't bring it into the house." ”

Tian's mother picked up Tian Zhuhai and slapped him twice.

Tian's father scolded: "You rabbit cub, you have to kneel, kneel your sister!" Your sister never knew where the pesticides were, and if you hadn't brought them in, how could the pesticides in the video be on the table? ”

Officer Black frowned and asked, "What about the bottle of pesticide?" ”

Tian Mu brought pesticides.

The black officer sniffed it, and the smell was very strong, it was a real pesticide.

Officer Zhang said: "Officer Black, this case is over? ”

Officer Black was still thinking quietly.

At this time, Wen Jiajia interjected: "Black officer, I think there is a problem with pesticides." ”

"What's the problem?"

Wen Jiajia showed the downloaded video of Tian Yan's suicide to the black police officer: "You see in this video, after the pesticide bottle fell to the ground, it did not produce foam. ”

The black police officer suddenly realized: "Xiao Zhang, take the pesticide back to test whether the residual concentration is consistent with the concentration of the original pesticide!" ”

Officer Zhang asked suspiciously, "Officer Hei, do you suspect that there is something wrong with this pesticide?" ”

Officer Hei said: "The clues provided by this female classmate are very good, if Tian Yan is not drinking pesticides, and the residual pesticides in this bottle are added later, then this case will be investigated." ”

"What? Is it possible that Tian Yan is not drinking pesticides? ”

"Yes, there is a big problem with her death."

Wen Jiajia said: "I always feel that there is something wrong with the video. ”

Officer Hei looked at Wen Jiajia and said, "You and I have thought together, this case is definitely not simple." ”

"Officer Black, I hope you can tell me if the case has a result." Wen Jiajia's tone was full of sincerity.

"Yes, yes, but why are you so interested in this case?"

"I ...... Well...... There is probably another person who has a trace of unbearability in his heart, wants to know the truth of the matter, and also wants to come to Tian Zhuhai's house to see and express his concern. ”

Officer Black smiled and nodded.

On the way home, Wen Jiajia couldn't help but ask Dongfang Tuo: "If, on the day you go back, will you still encourage everyone to make that decision?" ”

"Yes, because, if we don't, we don't know what will happen to you."

"However, this time it was at the cost of Tian Yan's life! The gacha became the catalyst for Tian Yan to be killed! ”

"How do I know! Yuwen Yan will pay the price of Tian Yan's life! I thought she would be careful! ”

"Yuwenyan wants to take advantage of the brother-sister relationship between Tian Yan and Tian Zhuhai, she doesn't want to cost Tian Yan's life, but she never thought that the wish she made was too big." Tian Jiajia said, "So, you think you're doing the right thing, it's just that you think." ”

"And can you think of anything else?" Dongfang Tuo roared.

Wen Jiajia was speechless for a while.

Dongfang Tuo continued: "However, you are really persistent enough, in that case, knowing that you will be disgusted, you even dare to vote no. ”

Wen Jiajia shook her head: "No, I didn't vote for that veto." ”

Dongfang Tuo frowned and looked at Wen Jiajia, she didn't look like she was telling a lie, who was it who voted for the veto and pushed Wen Jiajia into a situation that disgusted everyone?

Officer Hei returned to the police station and watched the video of Tian Yan's suicide over and over again, which was really disobedient, but he couldn't remember what went wrong.

"That's right!" Officer Black was suddenly surprised.

Tian Yan spoke as if reading a text, and there was a pause of a few tenths of a second between the two words hanging and reading in the sentence "Please don't worry about me", if she said it herself, shouldn't it be coherent? Even if you are a third-grader in elementary school, if you know a word, you can say it coherently.

Could it be ...... Did Tian Yan read what she said? Perhaps, the pesticide that Tian Yan drank was not a pesticide at all. Perhaps, Tian Yan didn't want to commit suicide at all, she just scared her parents because of her poor academic performance, so she was coaxed to record a suicide video and write a suicide note. Then, the murderer killed him again, using videos and suicide notes to create the illusion that Tian Yan committed suicide!

"Officer Black, the test results are in." Officer Zhang walked in, "The concentration is the same as the pesticide, it's original, that's right." ”

"Even if that's the case, it's possible that the killer washed the bottle with real pesticides." Officer Black was thoughtful.

"So, what we're going to do now is find out who really is the murderer."

The next day, the investigation team came to the vicinity of Tian's house to continue the investigation. At the same time, Tian Yan was autopsied.

The autopsy report showed that Tian Yan was poisoned by drinking inorganic substances mixed with colorless and tasteless, not because of drinking organic matter in pesticides.

"Officer Black, there's a big discovery." Officer Zhang ran over with something in his hand, "This was found in the garbage can." ”

"What is this?" The black officer looked at what Xiao Zhang was holding, a broken tin can, which smelled of pesticides.

"Could it be...... This is the murderer used to change the pesticide quickly, to check the fingerprints. ”

Officer Hei and Xiao Zhang knocked on the door of the Tian neighbor's house with the inspection report.

A scrawny old man opened the door, holding a puff fan in his hand, his speech was slightly slurred, but his thoughts were clear: "Please come in." ”

When I entered the house, the musty smell mixed with the smell of medicine rushed into my nose.

Officer Hei took out the report: "Old man, yesterday we took You Qu's fingerprints, and found that they were exactly the same as those on this tin can. ”

The old man tilted his head, closed his eyes, and a few cloudy tears welled up: "The tumor on Qu'er's face is getting bigger and bigger, and he doesn't want to go to school anyway, so it's okay...... Can I go and deliver medicine to him every day in the future? ”

Officer Black nodded, "We'll wait for him here." ”

At 6 p.m., You Qu came home from class, wearing the uniform of Fengwei Middle School, he glanced at the two police officers and sat down in his chair nonchalantly.

Xiao Zhang looked at You Qu's face and felt a little disgusted, and after being glared at by the black officer, he forcibly held back his disgusting expression and quickly returned to normal.

Officer Hei spoke: "Student You, I heard that you have always been an honor student in junior high school, how did you get into the worst middle school in the city?" ”

"I had a high fever on the day of the high school entrance examination, and I didn't do well in the exam."

"Oh, then, you don't have a good relationship with the Tian family brothers and sisters?"

"Huh?"

"Tian Yan didn't do well in the exam, and she was afraid of being scolded by her parents, so you coaxed Tian Yan to record a suicide video and write a suicide note. You colluded with Tian Yan to replace the pesticide with water, and let Tian Yan pretend to be a pesticide to drink it. However, if you add colorless and odorless poisonous inorganic substances to the water, Tian Yan can not only cooperate with you to complete the suicide video, but everyone will also think that she really wants to commit suicide. So no one doubts you. We found an old tin can in the trash near your house with pesticides in it. We suspect that you poured Tian Yan's pesticides into the tin can in advance, cleaned the pesticide bottle with water, and poured it into a highly toxic solution, and after Tian Yan drank it, you cleaned the pesticide bottle again, poured the pesticide in the tin can back into the pesticide bottle, and then poured out the pesticide, so as to create the illusion that Tian Yan drank the pesticide. We found this highly toxic substance in Tian Yan's body, and also found some iron oxide filings at the bottom of the pesticide bottle, which should have fallen from the iron can. The fingerprints on the tin can match you exactly. Therefore, all kinds of evidence show that it was you who killed Tian Yan. ”

You Qu, who originally wanted to struggle, turned pale when he saw this iron can, and after a while, he said, "I did it." But before you catch me, I want to stay with my grandfather for the last night. ”

The black officer said: "We will give you one night, and tomorrow you will turn yourself in, and you can be lenient." ”

"Okay."

On the way back to the police station, Officer Black was uneasy.

Officer Zhang asked, "What's wrong with you?" Isn't the case solved? ”

"You Qu clearly said that he didn't do it just now, why did he admit it when he saw the tin can?"

"It's normal for prisoners to go through this process of quibbling – seeing the evidence – admitting it themselves."

"No, after all, I've been handling cases for twenty years, and you've only been working for a few years? Based on my experience, his expression and tone of voice, it seems that he did not kill anyone, but after he saw the tin can, he knew some truths, which made him rather admit that he was the real murderer than shield someone. ”

Xiao Zhang's eyes widened in surprise: "What? ”

Officer Black lit a cigarette: "So, this case is not over yet." ”
