6-B, Head of Household: Xiu Mingrui)

It was an ordinary weekend, and Yin Xinshui took Liu Yan's arm and strolled happily through the seaside square. Actually, Yin Xinshui didn't know what kind of thoughts Liu Yan had, but Yin Xinshui knew that Liu Yan definitely knew that her happy smile was on the surface. Because of those bizarre and terrifying cases recently, the strong pressure made her a little anxious and depressed. Whenever this kind of strange thing happens, and it is difficult for the public security bureau to have a clue to peel off the cocoon, Yin Xinshui will feel a burst of redness on his face - everyone secretly talks about himself in unison, and the new police officers peep curiously, because they have heard all kinds of absurd anecdotes about Yin Xinshui's boyfriend before.

Every time she thought of this, she looked at Liu Yan casually, and there was inevitably some sadness in her eyes. Liu Yan also looked at her occasionally, smiled naturally, and couldn't see any flaws at all. Yang Zhaolin once prankfully suggested that Yin Xinshui pay attention to Liu Yan's dream talk at night, maybe he could set some earth-shattering secrets, Yin Xinshui's face turned crimson, and she argued that she had never spent the night at her boyfriend's house. Recalling all kinds of past, Yin Xinshui sighed and shifted his attention to the sea. Yanzhou guards the sea, but Yanzhou people's love for the sea has never been aesthetically fatigued, even in the cold and windy winter, on weekends, the number of people who come to the seaside plaza is still far more than the total number of customers in several large shopping malls. Moreover, in order to improve the appearance of the city and attract foreign tourism and investment, the municipal government did not hesitate to spend a huge amount of money to build a promenade park around the sea connecting the three districts, and the facilities have been renewed. The pleasant sea breeze beats the frolicking children and flutters their leisurely white wings.

Liu Yan said with satisfaction: "It's good that this place is open to everyone for free, and it's much better than spending money to go to a supermarket or shopping mall." ”

Yin Xinshui made him happy, and thought to himself: "You are real." Usually so frugal, last month suddenly pulled me to the shopping mall to buy a down jacket of more than 800 yuan, and said something like a princess, you are still weak after all. ”

The two built a castle on the beach. Yin Xinshui felt that his hands were very cold, and after piling up for a while, he sat on the stone bench and looked into the distance. Liu Yan aimlessly piled up with his hands, and actually piled up the bottom floor of a decent ancient building, although it was far from being piled up, Yin Xinshui could still see that this technique was as skillful as drawing circles with his hands. Although she was somewhat taken aback, she could also imagine this happening. The eyes of the surrounding tourists were attracted, and they thought that a professional sand sculpture art master had come, Liu Yan pushed it without regret, knocked down the sand sculpture building, and then took Yin Xinshui's hand and left quickly.

Yin Xinshui's phone rang suddenly, she glanced at Liu Yan, swept her hair to her ear, and heard Chi Mingtao's voice: "Xiao Yin! There was a homicide in the No. 9 middle school in the city, and you must arrive in twenty minutes! ”

Yin Xinshui clasped the phone and looked at Liu Yan apologetically. The nature of her work is like this, she rarely takes two days off a month, and when she encounters an urgent task, she will immediately cancel all scheduled vacations and return to the bureau to be on standby, so every day is very stressful, but this is her mission.

Liu Yan didn't have any obvious mood swings, just smiled and said, "It's okay, you can't run around the sea park, when you're done, do we have time." ”

Yin Xinshui smiled bitterly at him, and then waved to a taxi.

Twenty-seven minutes later, Yin Xinshui hurriedly flashed her police cards to the police officers who were about to stop her, and quickly crossed the cordon, it is said that she should have noticed the forensic doctors filming and collecting evidence indoors and the cold atmosphere emanating from the scene, but she was even more surprised that more than a dozen public security cadres were at the scene, including Gong Shuyi, the deputy director in charge of criminal investigation of the Municipal Bureau, and Qiu Shanlong, the public security director of Dong'an District, and their faces were solemn. Who is the deceased and will have such a big face?

After Yin Xinshui saluted the leaders, he quietly asked Yang Zhaolin: "Who is the deceased?" ”

"Mu Zhongkai, the principal of No. 9 Middle School, one of the top 100 educators in the country who was received by provincial leaders," Chi Mingtao explained, "was a female English teacher who was the first to find the body, and we rushed to the scene after receiving the report." Forensic ...... Zhou"

Forensic Doctor Zhou raised his head and lifted his glasses: "The time of death is about eight hours." He was killed by a pen ** in the forehead. The pen was not at the scene, but the size of the wound could clearly tell that the pen was the murder weapon. ”

Yin Xinshui trembled slightly.

Yang Zhaolin could see Yin Xinshui's doubts, and said in a low voice: "The murderer is good at martial arts, and he has a lot of strength, otherwise he wouldn't have killed him with a pen that wasn't sharp." But then again, a specially trained professional killer should be able to do this kind of thing. You don't have to worry about ......" Although the four words "your family Liu Yan" behind it were not spoken, they were self-evident. Yin Xinshui stayed with Liu Yan for eight hours in a row, knowing that it would definitely not be Liu Yan, but in case this murderer was as extraordinary as Liu Yan, it was difficult to say that he had no connection with Liu Yan.

Chi Mingtao shook his head: "No." It's hard to imagine a principal who has been on the front line of education for many years - even if he has won so many honors, he is always an educator, who would make enemies with him and send professional killers to kill him? Even if it is a professional killer, there should be many ways to kill a middle-aged and elderly literati in his fifties and with a good figure. Why use such a unique and difficult method to prove that your qualities are different from those of ordinary murderers? Isn't this self-defeating? ”

Forensic Doctor Zhou patiently waited for him to finish speaking, and then said, "Team Chi, I'm afraid this is not an ordinary professional killer. The strength is so great that it is difficult for ordinary people to insert a pen directly into the skull. And we observed that after the murderer inserted the skull, he stirred it again, which not only showed the murderer's deep hatred for the deceased, but also the key was ...... The wound that had been inserted into the skull for the first time was actually enlarged by the stirring pen, and such a force ...... I'm afraid no one can do it, right? ”

Although Forensic Doctor Zhou didn't know Yin Xinshui, let alone Liu Yan, this sentence made the arrogant and sensitive Yin Xinshui's face turn red again, and Yang Zhaolin and the others did not show their true thoughts as much as possible, but how could Yin Xinshui not know? As soon as there is an event that is impossible to explain, they will subconsciously see Liu Yan as the best candidate for the murderer.

Before waiting for the specific results of the forensic autopsy, everyone simply chose a quiet chemistry laboratory on the science and technology laboratory building for a meeting. Everyone thinks that the murderer should not be casually defined as a special person they know, who knows if there is anyone in the world who can easily break the skull with their bare hands?

"The deceased was the principal, which is special. There are so many people who know him, and I was still his high school classmate. "When Gong Shu spoke, everyone was very quiet, on the one hand, out of respect, on the other hand, it was rare to hear Director Gong personally analyze the case, maybe he also expressed his opinion at the time of the mysterious explosion in Qianlong Building, but that meeting belonged to the high-level, and even Qiu Shanlong was an ordinary audience, at most to the level of Chi Mingtao, Pan Tiezhi, Dong Yan, as for Yang Zhaolin, Yin Xinshui, Shen Qi and others did not have this qualification.

"Plus the school has a large number of people...... The good thing is that there is less liquidity. I suggest that we divide into two groups, one group of outsiders who enter and leave the school within a few hours before and after the time of death, including public servants, examination personnel, parents, students from other schools who come to the school to borrow a field to play ball, and even idle young people. The other group assumed that the former group did not find any suspicious people, and launched an investigation of the faculty, staff, and students on campus, and the murderers must be among these types of people. "He is a deputy director-level cadre, and it is impossible to be as clear as Chi Mingtao said, but everyone understands that Gong Shuyi said that as long as the murderer is a human being, or appears in human form, he always needs to rely on these identities to easily approach the principal and successfully assassinate him.

Qiu Shanlong continued: "The ninth middle school is the key of the city, and it is second only to the provincial key middle school of the sixteenth middle school in the ranking of the city's senior high schools. To be honest, the Municipal Education Commission originally planned to expand this place to further promote the reputation of the city's famous schools. But now that such a thing has happened, the superior leaders attach great importance to it and ask us to give a clear attitude and try to reduce the panic of the majority of students, otherwise it will not be conducive to their mental health and will have a negative impact on the gradually forming outlook on life. The homicide occurred in our Dong'an District, and the city leaders asked us to give a clear attitude, I had no choice but to make a military order to Secretary Wei and Mayor Tan, with a deadline of three months, and we must take down this case before the Spring Festival and present it to the New Year! Got a question? ”
