"Do you want to go back and rest?" Lao Chen asked.

"It's okay, just take a nap and investigate Wang Lin's online social situation?" Xu Tian said with his tired eyes half-open.

"It's basically the same as Bai Qi's explanation, except for that supernatural forum, Wang Lin has not been in contact with other problematic online social circles, nor has he found any other abnormalities."

"Maybe our investigation is in the wrong direction, and we should start from real life instead of giving up the Internet as an entry point."

"What do you mean...... Want to dig deep into Wang Lin's previous affairs? ”

"And Bai Qi, Xiao Shuang also has to investigate carefully, and Yanzi can't let it go."

"It's not easy to investigate this kind of thing, it requires a lot of visits, and Bai Qi may not cooperate with us, and the investigation of Xiaoshuang and Yanzi will also enter the circus to inquire, and it may not be rewarding."

"Then let's start with Wang Lin first! I want to go and see the scene of the crime. ”

Xu Tian and Lao Chen had some supper downstairs and then drove to Wang Lin's house, and at about two o'clock in the morning, the two came downstairs to Wang Lin's house.

"Wang Lin's family lives on the eleventh floor, which is the house with the lights on." Lao Chen pointed to the eleventh floor and said.

"The funeral hasn't been done yet, has it?" Xu Tian said.

"The body is still being examined, because Wang Lin's death is too strange, and her parents were at home when Wang Lin died. Wang Lin was alone in the room, and her parents could confirm that they had not heard any unusual sounds from Wang Lin's room that night, and no one had been in the house all day. Lao Chen said.

"If you're a murderer, I mean hypothetical! What would you do if you wanted to kill a stranger on the eleventh floor? ”

"What do you say? How can such a thing be assumed! ”

"Do you know how I reason? When it seemed impossible for a murderer to commit a crime, I would imagine myself as a murderer, and what I would do if I were a murderer and were to commit the same crime. ”

"So you're going to try to reason now?"

Xu Tian took a deep breath and tightened the coat on his body, the October night was very cold, and the fog could be seen when the two of them spoke.

Xu Tian closed his eyes and took Wang Lin on the eleventh floor as a hunting target, at this time Xu Tian imagined himself as a person who wanted to kill Wang Lin.

The lights are on at Wang Lin's house on the eleventh floor, and the time is around nine o'clock in the evening, although the night in October is relatively cold, but at nine o'clock in the evening, many people can still be seen walking around in the community, and the murderer can't hide himself at all in this community that is monitored everywhere.

So how do you kill Wang Lin? If the murderer was himself, then Xu Tian would have to find a way to make a phone call with Wang Lin, but in this way, after committing the crime, he would be exposed, and it was obviously impossible to make a phone call.

Another way is through the Internet, but in this information age, the Internet police can investigate the chat records of all chat software, and this method is obviously not good.

So how do you do it? The only way was to inform Wang Lin face-to-face, and Xu Tian would tell Wang Lin to tie one of his feet around nine o'clock in the evening, tie the other end of the rope to the radiator, and hang himself upside down from the window.

That's right, the only way the murderer can use is to let Wang Lin do it himself, unless Wang Lin's parents lied, or Wang Lin's parents were the real murderers. But this situation is impossible to happen, Wang Lin is the biological daughter of her parents, there is no conflict in the family, and their whole family has no history of mental illness, and the murderer cannot be Wang Lin's parents.

As Lao Chen said, on the day of Wang Lin's death, her parents did not hear that there was anything abnormal in Wang Lin's room, and no one from the family came that day, and there were still people moving around in the community, and there was surveillance everywhere.

In this kind of well-arranged crime scene, the only person who can commit the crime is Wang Lin himself.

But this assumption is very unscientific, why did Wang Lin commit suicide? What is the motivation? There is also a blade found on the vertical ground at the scene of Wang Lin's death, and the wound on Wang Lin's neck is completely consistent with the blade, but the fingerprints on the blade have been wiped by someone, and the bloodstain reaction detected is indeed Wang Lin's blood.

Thinking of this, Xu Tian pointed all the questions to the blade, that's right, it was the blade that looked like the murder weapon, which was extremely similar to the flying knife that Xiao Shuang found after his death, and the two crime scenes only thought that the deceased could be killed by him through the murder weapons.

Xu Tian suddenly came to his senses, and at this time, Xu Tian only had two objects in his mind, a blade and a flying knife.

"Officer Chen, we may be wrong again." Xu Tian said.

"What? Do you have something in mind? Lao Chen asked in surprise.

"Giving up the investigation of the crime scene, we still have to trace the interpersonal relationship of the deceased."

"What the hell is coming to mind?"

"This case may be more complicated than we expected, it is useless to find the method by which Wang Lin and Xiao Shuang were killed, we have to find out the reason why Wang Lin and Xiao Shuang were killed!"

"But the reason why they were killed is the most difficult to investigate, and now there is no entry point at all, I understand what you mean, Wang Lin and Xiao Shuang may have done something wrong before, but their parents and friends may not know much about this kind of thing, if they made a major mistake, it is even more impossible to tell others about the mistake."

"Bai Qi has already told us the entry point, the supernatural forum, the one called the suicide girl is our entry point."

Xu Tian and Lao Chen immediately returned to the police station, and the two inquired about the identity of the girl called suicide with the cooperation of the Internet police, but unfortunately, when Lao Chen took that person's ID number to check on the household registration network, he found that the owner of the ID card had passed away, and what was even more coincidental was that the person called the suicide girl was the same age as Wang Lin and Xiao Shuang, and she was also a flower girl.

"It's even more troublesome now!" Lao Chen said distressedly.

"Let's investigate the cause of the death of the girl who committed suicide!" Xu Tian said with a sigh.

Fortunately, the person named the suicide girl is registered in Dong'an City, so it is much easier to investigate.

Through Lao Chen's investigation, the person who called the suicide girl with the screen name is called Zhao Di, who committed suicide by jumping off the viaduct two years ago, and the case file at that time is still kept, and Lao Chen also remembered the suicide case when he saw the case file.

At that time, Zhao Di was sitting on the guardrail of the viaduct, and there were many onlookers at the scene, but unfortunately, before the police and fire brigade arrived, Zhao Di jumped down.

"That's not right! If Zhao Di had committed suicide two years ago, then Bai Qi said that the suicide girl cursed them to die before the three of them met each other, which happened a few days ago, but the suicide girl had died two years ago! Xu Tian said.

"Then it's obvious that someone used Zhao Di's to curse Bai Qi, Wang Lin and Xiao Shuang on the forum." Lao Chen said.
