The sea and the book [criminal investigation]

Qu Man's words are not credible.

But she would admit that she deliberately led her classmates to bully Yu Xiaohua on campus, which already surprised Lu Nanchu.

If the campus bullying incident seven years ago was a premeditated and purposeful act, Chu Man would bear the most direct responsibility for Yu Xiaohua's death.

But according to Chu Man, the cause of Yu Xiaohua's death was still suicide.

This is contrary to another piece of evidence that Lu Nanchu has, which comes from Yu Xiaoyu's memory.

"There is one more question, I hope you can explain it to me together." Lu Nanchu found from the case files seven years ago the relics of Yu Xiaohua who had been sealed in the files as evidence, that is, the love letter to Zhao Yiqin.

In Yu Xiaoyu's memory, Yu Xiaohua didn't like Zhao Yitan at all.

Yu Xiaohua once asked Yu Xiaohua if she liked anyone, and Yu Xiaohua said frankly that she didn't like anyone, saying that everyone around her was not as fragrant as Two-dimensional paper people.

Except for the love letter in Yu Xiaohua's handwriting, there is no other trace that Yu Xiaohua has a crush on Zhao Yitan, and she has never even been to the fourth class downstairs.

These signs do not match the behavior of a crush.

That love letter now looks more like a deceptive evidence.

If Yu Xiaohua committed suicide, as Yu Xiaoxiao said, it is impossible for her not to leave a few words to her relatives, but to express her affection to a crush.Even on the day Yu Xiaohua committed suicide, she made a clear plan for the future, and all these signs were not like the behavioral psychology of a suicide.

In order to solve this doubt, Lu Nanchu re-studied the love letter, and finally found a clue.

This love letter is most likely written by Yu Xiaohua for someone else; because the statement in the letter does not resemble her own tone, the information is revealed from the description between the lines.

She said that she would go to Linning to study in the future, and an outstanding student like Zhao Yiqin must be a reserve member of Yunda University. Maybe she would have little chance to return to Yunying after graduating from high school.

But Yu Xiaohua's situation is different. Her cousin Yu Xiaohua has already sent her to Yunda University, and she and Yu Xiaohua meet to go to each other's universities to play. answer.

"Besides, what Yu Xiaohua wants to be admitted to is not Linda University, but Gome, so it is impossible for her to mention in her letter that she is going to Linning University to study." Lu Nanchu exposed the falsehood of the love letter bit by bit.

"Impossible! What Yu Xiaohua filled in on the voluntary wall is Linda." Qu Man turned pale with shock, and shook her head in denial.

"That's why you believe that Yu Xiaohua's dream love school is Linda University, and you are so confident that you dare to write this information in this love letter? If I'm not wrong, you actually asked Yu Xiaohua to write this love letter?" Lu Nanchu said After guessing, Chu Man's expression became a little stiff, she bit her lower lip slightly and did not speak.

The love letter was ghostwritten, and the only thing that can point to it is that Yu Xiaohua's death was indeed murder.

And the person who asked Yu Xiaohua to write this love letter is without a doubt the number one suspect.

According to Yu Xiaohua’s diary, she was isolated and bullied by her classmates in her class. For her, everyone else in the class was bullies or bystanders. It was impossible for her to write love letters for these people; They are her good friends, but Li Chen'er thinks that their friendship has already broken down.

Seeing that Li Ju'er remained silent, Lu Nanchu was ready to get up: "Actually, even if you choose to remain silent, we will find out the truth. You have to understand that if you are honest, you will be lenient, and if you resist, you will be strict."

"Then what answer did Police Officer Lu want to hear?" Chu Man sneered, looked up at him, and said with a half-true smile, "Yes, as you can see, Yu Xiaohua was indeed killed by me. She I had a cold, so I stole her sleeping pills, crushed them into powder, and told her it was a cold medicine my mother gave me; she took it without any doubt. Am I smart? She took the medicine voluntarily Yes, I didn't force her to eat it with a knife. No one doubted me, after all, I asked for leave and went home that night. "

Chu Man blew himself up again, but it still made Lu Nanchu feel that something was wrong.

Whether it is deliberately leading classmates to bully on campus, or her current statement of changing medicine to harm others, there is no motive to kill.

Friends breaking up because of conflicts, or jealousy, it is hard to imagine that they will constitute the motive of killing.

"Comrade policeman, don't worry, I will never overturn my confession. I have always been a brave person. If you find me, I will tell the truth, and I will not make up a set of lies. I’m here to lie to you.” Chu Man suddenly became serious about death, completely opposite to her silent attitude just now.

As for how credible her words are, it's hard to say.

There may be someone behind Chu Man, such as who deleted the comments in Peng Peng's account, and Chu Man's account is also clean, which must be to cover up some unknown things.

Juman’s confession is also progressive; at first she insisted that she had nothing to do with Yu Xiaohua’s case, then she admitted that she deliberately led her classmates to isolate and bully her because she was jealous of Yu Xiaohua, and now Lu Nanchu admitted that she was She changed her dressing and tricked Yu Xiaohua into taking a large dose of sleeping pills, which directly caused Yu Xiaohua's death.

Intentional homicide is the most serious crime.

In the conjecture with insufficient evidence, the police really suspected that Li Chen'er was the prime suspect in the murder of Yu Xiaohua; now that the suspect has voluntarily stated the crime, the case is too simple to solve.

Seven years ago, Li Chen'er tried her best to fake Yu Xiaohua's death as a suicide. She was very successful. For at least seven years, no one suspected that Yu Xiaohua's death was something strange.If it weren't for this serial murder case that happened to involve the sisters of the Yu family, the truth of Yu Xiaohua's death would have been buried underground forever.

But Li Jun'er didn't even struggle a bit, Lu Nanchu and Guo Chen took turns talking a few times, and she directly explained her crime history?If Li Chen'er really had this understanding, she would never have committed any crimes seven years ago, and all her reactions now seem very unreasonable.

Coming out of the interrogation room, Guo Chenxu broke into a sweat: "Old Lu, do you think this little girl is trying to deceive us? She deliberately dug a hole to lure us to jump down."

"What do you think?" Lu Nanchu asked him back.

"This is the first time I have met a suspect who is so 'cooperative'." Guo Chen also felt that it was against harmony.

In fact, the colleagues of the entire criminal investigation brigade felt the same after reading their interrogation and answers. It was precisely because the interrogation of this case went so smoothly that they felt an indescribable strange feeling.

The cooperation of the vines is like the calm before the storm, waiting for the storm that may come at any time.

Lu Nanchu heard the discussion among them, but he still made a firm decision: "This written confession, as well as audio and video recordings, can prove that the suspect himself admitted the fact that he drugged and killed. Even if she wants to retract the confession in the future, even if the king of heaven comes It’s hard to say without ironclad evidence.”

After seven years, it is even more difficult to find the evidence at that time, and there are no witnesses about her drugging.

Qu Man can obviously be washed away, as long as she insists that Yu Xiaohua committed suicide because of campus bullying, no one can charge her as a murderer until other evidence is found.

But she confessed her crime in such a hurry, but she seemed to be afraid of something.

"Captain Lu, Captain Guo. Li Ju'er is admitting to drugging the deceased. I think it may be because Captain Lu said at the time that even if you choose to remain silent, we will find out the truth." Nan Zhao watched the surveillance video repeatedly, pointing out that at that time Qu Man's suspiciousness, "When Lu Dui said this, her expression was guilty and flustered."

Chu Man was very afraid that the truth would be found out, so she automatically confessed the truth?It doesn't make sense either.

Unless what she said is all false and she uses fabricated content to cover up the truth, after the fabricated content is overturned, she may be presumed innocent.

But because after so many years, Chu Man was the only person involved, and there were no other witnesses; so it is very likely that what she made up, the moment it came out of her mouth, the fake became true .

Qu Man made up stories to prevaricate the police, and even made herself the murderer in the story. What could be her purpose?These things all seem very strange.

Intentional homicide, the most serious crime can be sentenced to death.

"Captain Lu, let Xiaoshu and I go test Li Ju'er tomorrow." Nan Zhao volunteered, "I'll go test Li Ju'er. Face-to-face contact should be more effective."

Now the first thing to do is to find out Li Ju'er's real motive for the crime. Her self-reported murder because she was jealous of her classmate sounds... also weird.

Investigating Li Ju'er's social contacts and contact records, no suspicious content has been found for the time being.

But after knowing that hackers were involved in the case, Lu Nanchu no longer believed in things that use the Internet as a medium.

What they can see is what the technicians behind the network want them to see. Sunny can hack the system silently, and embed other things in the program code of the system, so it is impossible to prevent other things from being tampered with.

The Yunying police have already applied for technical assistance from the Security Bureau. As for whether they can defeat the hackers, let's talk about it.

"I thought of a question. Why did Li Ju'er come to Yunying at this time? She hasn't been back since she was admitted to university." Yan Geng flipped through Li Ju'er's information, and was very puzzled by this point.

The well-informed Shu Manyue said: "The stage play tour at the end of the month, the first stop is Yunying, and Li Ju'er is the heroine of the stage play."

The crew of this stage play was also quite unlucky. Before the tour, the heroine was arrested on suspicion of murder.

According to the normal psychology of criminal behavior, criminals who escaped smoothly after killing people will pay close attention to this case, and any trouble can make them vigilant.The re-investigation of Yu Xiaohua's case is not a secret. The police asked the teachers of Yunxi No. [-] Middle School several times for information. If Li Chen'er pays attention to this case, she will definitely notice it; but she can still return to Yunying as if nothing had happened. Mental quality should not be underestimated.

Another problem is that Li Juer was involved in the previous case of Chen Xuanyue and Zheng Peizhi, and was accused of being a third party who meddled in other people's marriages; after Chen Xuanyue's death, the headquarters of Yunjia Group sent new leaders to manage Yunjiao Xingyi.Li Chen'er is the signed artist of Yunyan Xingyi, but she doesn't seem to be implicated in any way because of this incident. The resources Yunyan Xingyi gave her are still so good that other artists can't match.

There are too many unreasonable things, but where is the root cause of the problem?
