He Jun is He Yao's younger brother, 22 years old this year, and originally studied at a vocational and technical school in R City. At the beginning of his junior year, because he was not interested in his major, He Jun resolutely dropped out of school despite the opposition of his parents. Because of this incident, his relationship with his parents was very stiff, and it was not until He Yao was killed, they lost their common relatives and needed to comfort each other, and the relationship eased slightly.

Although the relationship with his parents is not good, He Jun's feelings for his sister are still very deep. It is understood that He Yao has always been very fond of He Jun, although she does not know programming and does not understand any kind of computer language, but she supports her younger brother's interests and hobbies, and also respects her brother's choice to drop out of school. In He Yao's eyes, He Jun is a smart and assertive boy, and she believes that her younger brother can live well with his own skills, instead of asking him to find a stable and decent job like his parents.

He Jun had a criminal motive for killing the "nail killer", but there is no evidence that the case was related to him. In a similar situation, there is the first clownfish case, An Ziyang has the criminal motive to kill Ma Zhichen, and even premeditated the crime. But the results of the investigation showed that when Ma Zhichen was killed, An Ziyang had a very clear alibi.

There is also a second clownfish case, the police once suspected that the murderer of Li Baofang was Zhang Anjian, the father of the girl Zhang Guoer, who was killed seven years ago, but the man committed suicide by jumping into the river as early as early 2014, and no one has been seen alive or dead.

Every clownfish case seems to have a suspect worthy of suspicion, but it is only a suspicion, and the case cannot move forward.

Gu Song had imagined a question before: Could the criminal gang that created the clownfish series of murders be an alliance of many victims? They achieve revenge by exchanging killings, so that even if the motive of the crime is suspected by the police, they can come up with a perfect alibi. Just like when Ma Zhichen was killed, An Ziyang was eating hot pot with a group of classmates, and that meal happened to be his treat.

When Li Baofang was killed, except for Zhang Anjian, whose fate was unknown, the families of the other victims had no possibility of committing the crime after investigation. And even if Zhang Anjian is still alive, he is already forty-three years old this year, which is inconsistent with the conclusion of the police investigation and interview: the murderer is a young man.

The police speculated that the "nail killer" Liu Fan was arrested by the murderer in Jinshui County. The three victims killed (injured) by Liu Fan were: He Yao, a 24-year-old cosmetics salesman, Xu Zilin, a 47-year-old self-employed person, and Wu Kaifei, a 16-year-old high school student.

Xu Zilin is a divorced bachelor whose relatives live in other places, and there is no one around him who wants to avenge him. Although Wu Kaifei's family lives in Jinshui County, he only suffered a few stab wounds, his physical condition is fine, and his family has no obvious motive for committing the crime. Only He Yao's younger brother He Jun is haunted by his sister's death, but he is an out-and-out otaku, he never left the house during the crime, and theoretically has nothing to do with the clownfish murder case.

In the latest villa murder case, the family members of the victim Ji Lan are all out of town and are not suspected of committing the crime. Jiang Peiyao, who escaped death, only has a fifteen-year-old sister who temporarily lives in R City, but she obviously cannot be the murderer of Dr. Li.

Therefore, if it is suspected that the Clownfish Killer is a relative of the victim's side, they can only achieve revenge by exchanging each other's killing targets. However, there was no evidence to support such speculation, and it was not until He Jun's name was mentioned again that Gu Song suddenly felt that this boy with special skills might play a very important role in these cases.

imitating the murderer's tone and indiscriminately posting on the Internet to provoke the police; On the night of Dr. Li's murder, he attacked the community's surveillance system to disguise the identity of the killer; Using online resources to collect private information about the target of the crime, etc., these tasks seem to be very suitable for He Jun. Although so far there is no evidence that he did these things, his suspicion of crimes is on the rise.

Gu Song told Qiao Sheng the truth about his speculation. Qiao Sheng agreed with his idea, and the two of them immediately decided to go to He Jun's house to find out.

Since dropping out, He Jun has been renting a high-rise apartment near the school. He doesn't like to go out, he doesn't like to socialize, he stays in his small room every day, orders takeout for all three meals a day, and buys almost all daily necessities online. As a last resort, he resolutely did not leave the house, and really brought the spirit of "home" to the extreme.

Gu Song and Qiao Sheng originally thought that He Jun was a person who didn't even bother to throw away garbage, and there must be nowhere to put his feet in the house. He himself should be the kind of unkempt and sloppy decadent image, but the reality breaks their stereotype of otaku.

The young man who appeared in front of them was wearing a spotless white pullover sweatshirt, light blue jeans, and his hair and beard were neatly tied, giving him a very refreshing feeling. And the small apartment he rented was also well organized, and all his belongings were put in order.

At eight o'clock in the morning, the hungry He Jun was anxiously waiting for the takeaway brother to deliver breakfast. He Jun felt a little unhappy about the inopportune visit of the two policemen, but he did not refuse to cooperate with the investigation. He invited Gu Song and Qiao Sheng into the living room, and he waited at the door for a while.

After getting breakfast, he asked Gu Song if he could give him a little time to eat while it was hot. Gu Song didn't eat breakfast himself, but he missed his mother's steamed beef dumplings very much at this time. But what could he say but agree, he couldn't let anyone else go hungry with him.

Taking advantage of He Jun's meal, Gu Song simply "visited" He Jun's bedroom with permission. As Gu Song imagined, this twenty-two-year-old boy likes games and anime, and a dazzling array of hand-made models is placed on a whole wall, and even Gu Song, an ignorant person, knows that these things are worth a lot of money.

However, for the items in this bedroom, Gu Song was most interested in He Jun's laptop. At this time, the special computer was placed on the computer desk next to the bed, within reach, but he knew very well in his heart that as a hacker, He Jun could not let an outsider casually snoop on the secrets hidden in his computer.

Is there any other evidence that there is some kind of connection between He Jun and the clownfish? Gu Song thought hard, but unfortunately couldn't find an answer.

"Officer Gu?" He Jun came out of the bathroom after washing his hands, and when he saw Gu Song staring at his laptop and contemplating, he couldn't help but joke, "Do you particularly want to open my computer now to see if there is any illegal information hidden in it?" ”

"You don't need to open it to know, there must be a lot of unsavory secrets in it." Gu Song turned around and said to He Jun in the same mocking tone.

He Jun shrugged his shoulders and did not admit it, nor did he deny it. He asked Gu Song, "You came to me early in the morning, wouldn't it be for the trivial things I usually do?" As far as I know, the leader outside is not small. He Jun said and pouted in the direction of the living room, "The leaders of the provincial department personally came out to investigate me, there must be some special reason, right?" ”

"Yo, you know a lot, and you know our leaders."

"I didn't know each other, but I found out when I looked it up, it's just a matter of a few minutes."

"yes, I almost forgot what you do. You're so powerful, you can easily find any information you want with just a finger move. In fact, it would be a pity that a talent like you did not come to our public security department to display your talent. ”

"There's nothing to worry about, anyway, I don't like dealing with the police, and I don't like to do unrestrained work."

Indeed, a man is accustomed to freedom, and it is difficult to restrain him by rules. But you can't live like this for the rest of your life, can you? Are you never going to reconcile with your parents? They're left with a son like you now. ”

"So what?" He Jun frowned unhappily, he didn't like others to judge his lifestyle, especially after his sister's death, he didn't want any change in his life. "Everyone has their own favorite way of life, and I haven't done anything harmful, why do you care about other people's family affairs as a policeman?"

"I don't want to care about you, I just think your parents are quite pitiful, they just lost their daughter, can't you compromise a little for them?"

"So why should I compromise, not theirs? You said they lost their daughter, but I also just lost my sister, the only person in the world who understands me, appreciates me, supports me, and respects me. ”

"Since you care so much about your sister, you should try to repair your relationship with your parents, isn't this what your sister tried to help you do when she was alive? Let you understand each other and tolerate each other. ”

"Cut, you know the." He Jun showed a disdainful expression, and said angrily, "My parents don't look down on me at all, they think I'm ashamed, I can't get a diploma in a vocational and technical school, they say that I stay at home all day and have nothing to do, and they don't want to mention me in front of relatives and friends, as if there is no son like me." If it weren't for the funeral for my sister, I wouldn't want to contact them, listen to them count me down and nag me. ”

"They're worried that you don't have a stable job and won't be able to support yourself."

"Forget it, they only care about their own face, when did they consider my feelings. Growing up, they didn't know what I really liked, only my sister...... Alas, forget it...... "The more He Jun spoke, the more impatient he became, he waved his hand and said to Gu Song, "Your criminal police in the serious crime team won't be idle and have nothing to do, right?" Did you come all the way to my house just to preach to me? ”

"Of course not." Gu Song smiled faintly and said, "You are an adult with opinions and ideas. As an outsider, I am not qualified to preach to you. I just hope you make the right choices and don't give yourself a chance to regret it, whether it's your life, your career, or ...... Your sister's business......"
