The sea and the book [criminal investigation]

When Lu Nanchu returned to the bureau, the technical department had already sent him a copy of the contents of Zhao Tian's phone.

赵恬溺亡的时间是7月21日早上9点左右，在他的手机中发现他和一个心理咨询师相约在7月19日下午3点见面，而这个心理咨询师的备注名是芃芃。

However, Pengpeng's mobile phone number was found to be empty, and behind it was a mobile phone card purchased anonymously.

Li Ye is the psychological counselor of Qingtian Psychological Institute. As for whether the psychological counselor Peng Peng contacted by Zhao Tian is actually Li Ye, no evidence has been found yet.

However, there is no Zhao Tian's name in the appointment list of psychological counselors in Qingtian Psychological Institution, and there is no trace of contact with Zhao Tian in Li Ye's mobile phone.

Obviously, this psychological counselor, Peng Peng, is very suspicious.

After Zhao Tian met with a counselor, he drowned in the river two days later; but the counselor disappeared without a trace, and then Li Ye, who was the most suspected, also died strangely. It is very doubtful whether it might be the real murderer Deliberately blame.

On the contrary, there is no evidence to prove that Li Ye met Zhao Tian.

It is possible that Zhao Tian was deceived, and the psychological counselor he saw might be an impostor, and this person is likely to be the key clue to Zhao Tian's death.

However, this person disappeared like a vapour, and finally he had to go back to Li Ye for a thorough investigation.

Although Li Ye has numerous enemies on the Internet, in her real life, no one knows that she is a painter Peng Peng. According to her colleagues and friends, Li Ye is a good girl who works hard and is strict with herself.

Lu Nanchu sorted out the information of the three deceased, and found that the three deceased had a common characteristic, that is, their relatives and friends around them all praised them for being serious in work, easy to get along with, and kind to others.Although there is a factor that the dead are the greatest, such a consistent dictation is at least [-]% credible.

But it is not easy to draw a conclusion on whether he is really a kind person or not.

Just like Li Ye's colleagues, relatives and friends don't know that she is a repeat offender of plagiarism on the Internet, and she also likes to lead wars to become a keyboard warrior.

This just provided Lu Nanchu with an idea, and also checked Zhao Tian and Feng Jingjia's online social relationship to the bottom.

Zhao Tian is actually a person who doesn't surf the Internet at all, he doesn't have any social network accounts, and the only use of his mobile phone is to contact Mu Yao.

And Feng Jingjia's situation is exactly the opposite of Zhao Tian's. He is still an Internet technology celebrity, and he is eager to help. Netizens privately asked him professional questions and answered them one by one.

What is complicated is that the situation is Li Ye. In addition to the big name Pengpeng, Li Ye also has at least a dozen small accounts. These small accounts are all scattered on the Internet, which further proves that she is genuine. He is a keyboard warrior.

Moreover, the content of Li Ye's wars is not limited to the comic circle, but also the wars of other large circles and small circles.And Li Ye also likes cross-circle law enforcement. She has at least five trumpets dedicated to the entertainment industry. Every day, she pushes and stomps on celebrities to write small essays.

From this point of view, the three deceased were indeed people with completely different personalities.

In addition, the test results of the turning lights of Yunjia Mall have also come out.

The traces left by the four screws of the turning lights falling off show that the screws are not old and naturally falling off, but were removed by external force; moreover, the lights of Yunjia Shopping Center are switched on and off at the control center, and the switching speed of the turning lights is also regulated by the control center. There are many places where you can do tricks.

The police checked the surveillance video of Yunjia Mall. The surveillance video was automatically covered for seven days. There was no abnormality in the video for the past seven days—that is to say, the screw for turning the light was pulled out by external force at least seven days ago. If the light does not turn on the speed, the risk of falling is almost negligible.

Seven days ago, it happened to be around the time of Zhao Tian's accident.

The mall employees who were on duty at the control center on the day of the incident were found, and the police summoned them for questioning.

The mall employee is Yu Shun, an old employee of Yunjia Mall.

The police summoned Yu Shun to say hello, and at the same time investigated Yu Shun's social relationship and journal information.

Yu Shun is over fifty years old, and his family is simple. He and his wife, He Fang, both work in Yunjia Shopping Mall; he is the administrator of the backstage control center, and He Fang is a warehouse worker.Yu Shun and He Fang have a 25-year-old daughter named Yu Xiaoyu, who is mentally handicapped.

Yu Shun also has a younger brother named Yu Gu, and the two families have close contacts.Yu Gu runs a breakfast shop. There is a son and a daughter in his family who died seven years ago.

Yu Shun timidly sat on the interrogation chair, with his head down, as if he was too timid to speak.

"Yu Shun, from Yunying Nancheng District, 53 years old, administrator of the control center of Yunjia Shopping Center?" Lu Nanchu looked at Yu Shun's information and asked, Yu Shun looked up dully, with a panicked look: "Comrade police, I really I didn't do anything bad! I didn't kill anyone!"

Lu Nanchu asked him: "At 8:2 p.m. on August [-], the turning light at the entrance of the DCT Comic Exhibition Center on the fourth floor of Yunjia Shopping Center fell, hitting a girl and causing her death. According to our investigation, it was because the screw of the turning light was loose, and it was just right. The turning speed was too fast, which caused the turn light to fall. You were on duty in the backstage control center at that time? Did any suspicious people enter the backstage control center while you were on duty? "

Yu Shun thought for a long time before he said with a trembling voice: "August 8nd, the DCT Comic Exhibition was held in our shopping mall that day, and the lighting on both sides was different. Although I was on duty that day, the manager was afraid of making mistakes, so he specially arranged for the Three colleagues were called in to help watch it at the backstage of the control. There is also a batch of fireworks from the exhibition in the utility room inside the control center, and the people who arranged the venue have also entered the control center.”

In other words, there were a lot of people entering the control center during that time period, and these people had full access to the turn light control.

Before the accident, none of them expected that someone would use the turning lights to kill people, and it was impossible for the staff to keep an eye on the control switch all the time, and it was common for them to walk away occasionally during the shift.

And the duty manager also mentioned that the shopping mall light switch in the control center can be used by appointment, and the scope of contact is even wider.

Yu Shun looked honest and honest; if you want to identify a suspect in a group of people at a glance, he is the most likely to be directly ignored.

Nan Zhao sat next to the recorder and listened to the trial, carefully observing Yu Shun's expression and state throughout the process, and he really couldn't see anything unusual.

"Okay, thank you for your cooperation. We may ask you to cooperate with our investigation at any time in the future, and hope to keep in touch with you by phone." Lu Nanchu checked his file and found nothing wrong, so he got up and sent Yu Shun out.

"Okay, okay, comrade policeman, I know what to say." Yu Shun responded repeatedly.

Yu Shun's wife, He Fang, was waiting outside with her daughter, and Lu Nanchu happened to see their family when he came out.

He Fang held her daughter's hand tightly. The girl wore two braids and looked curiously at the police station hall.

Seeing her husband coming out, He Fang finally let go of her tense heart, and quickly went up to meet her: "Are you all right? Are you all right? As long as you're all right."

"Uncle, here's Tangtang." The girl followed her mother with an innocent smile, took out a candy from her pocket and wanted to hand it to Lu Nanchu.

When investigating Yu Shun's social background, Yu Xiaoyu was his daughter, and Lu Nanchu also read her information, and felt very sorry for this girl.

Yu Xiaoxiao was an outstanding student in the physics competition class of Yunxi No. [-] Middle School seven years ago. He participated in IPhO twice to win gold and was recommended by the Physics Department of Yunying University.But because of being stimulated by the death of his cousin Yu Xiaohua, he stumbled and fell down, broke a leg, and became a fool.

What a good girl she used to be, but now she has become like this, it is really embarrassing.

But when he knew that Yu Xiaoyu was a student of Yunxi No. [-] Middle School, Lu Nanchu was still surprised for a moment.

He remembered well that Mu Yao was also a graduate of Yunxi No. [-] Middle School.

And according to the calculation of time, Yu Xiaoxiao and Mu Yao are still students in the same class, but Mu Yao is a student of the liberal arts class.

It's a pity that the world is unpredictable, Mu Yao was admitted to the Department of Literature of Yunying University with excellent grades, but Yu Xiaoyu, who was recommended to go to Yunying University, has become a mentally retarded disabled person whose intelligence is equivalent to that of a three-year-old child.

But there is a piece of information related to Mu Yao's sister, Mu Tao.Mu Tao turned out to be the head teacher of Yunxi No. [-] Chinese class, and Yu Xiaohua's cousin, Yu Xiaohua, was Mu Tao's student.Seven years ago, Yu Xiaohua committed suicide because of campus bullying. Her class teacher, Mu Tao, took the main responsibility for this incident, so she took the blame and resigned and left Yunxi No. [-] Middle School; Bullied and committed suicide by swallowing sleeping pills, but the case file of Yu Xiaohua's case is not filed in the Public Security Bureau.

For this matter, Lu Nanchu went to Wang Ju to inquire about it. Wang Ju had some impressions of this case, so he said: "The case happened exactly seven years ago. Campus bullying led to suicide and death of students, which caused widespread social concern. It had a very bad impact, and the case file was directly sent to the higher authorities for review. Later, because of this case, the law was spread in schools across the country, and school bullying was strictly controlled to prevent similar incidents from happening. If you want to see the file of Yu Xiaohua’s case, you must first file a callback application. "

Hearing what Wang Ju said, Lu Nanchu also remembered that there was such a thing.

Seven years ago, because of his mother, he was transferred back to Yunying to take over the work of the criminal police of the city bureau. He heard from Qin Zheng that there was a serious school bullying incident in Yunxi No. Due to the bad influence, the Yunying police recently cooperated with the Education Bureau to enter primary and secondary schools in Yunying District to conduct publicity lectures on preventing school violence.

It seems that Yu Xiaohua's case happened not long before that.

And Yu Xiaoyu was in a trance of grief because of Yu Xiaohua's death, and he stumbled and fell into his current appearance.

I don't know whether to make people feel the deep love of their sisters, or to feel sad about their experience.
