Song Yi agreed very much with Qin Nan's reasoning just now. If he followed the direction of his reasoning, all the mysteries in this case would make sense. But the current situation is,
The evidence is a little lacking. He has never seen this method that can hypnotize people to commit crimes, and he doesn't know if such a thing really exists.
He thought for a while and said to Qin Nan: "Old Qin, I think your reasoning is very correct, and I agree very much, but judging from the current evidence and clues,
The murderer can hypnotize people and then kill them. This unlikely method of killing seems like..."
Qin Nan was also expecting Song Yi's reaction, so he said to Song Yi: "Old Song, why don't we go up and investigate the surveillance video?
As for the school, you can ask the criminal policeman who is watching the scene to find a way to copy the surveillance video of each gate of the school, as well as the boys' dormitory and the teacher's dormitory. It should be fine."
Song Yi nodded thoughtfully, and then called the criminal police over there to copy the surveillance video.
Song Yi and Qin Nan left the archives room. At this time, Ma Xiaotao was leaning against the wall beside him, with his hands on his hips and his brows furrowed. He didn't know what he was thinking.
After seeing the two people walking out, Ma Xiaotao followed them. When Song Yi saw Ma Xiaotao at this time, he could roughly guess what she was thinking.
About half an hour later, the criminal police from the school copied the information to the mailbox, and the three of them sat in the office and read the contents bit by bit.
I don’t know how long I watched, but I finally found a clue in the surveillance.
The black clinic selling human organs was destroyed in October, that is, at the beginning of last month, and Lu Fei was destroyed at the end of August.
He did not go to and from the black clinic regularly every week, but after the black clinic was sealed and destroyed, Lu Fei would go to the back door of the school every now and then at night and take a different taxi every day.
Song Yi discovered during the surveillance of the traffic control department that after Lu Fei got into the taxi photographed in front of the school at night, the next time the taxi appeared in the surveillance, there was someone else in it, or there was no one at all.
But when I go home every evening, I always show up at the back door of the school on time, and then I rush downstairs to my dormitory at almost the same time every day.
Xiao Lu was also in the taxi following Lu Fei, but again, Xiao Lu's drop-off location could not be found, and the surveillance near the black clinic did not detect her.
Sometimes Xiao Lu would go back to school, and sometimes she would go back to school the next morning. If she didn't associate Xiao Lu with these things, it would be impossible to see what was wrong with her.
The three of them watched the surveillance for three full hours in front of the computer. Unknowingly, it was already eight o'clock in the evening.
Song Yi looked at his watch and signaled Qin Nan and Ma Xiaotao to go home and rest first, and then continue the investigation tomorrow.
Later, Qin Nan took Song Yi's ride and returned home.
It was already ten o'clock in the evening when he got home. He was indeed exhausted from today, so he went straight into the house and lay down on the bed.
Just as he was about to put on his pajamas and go to bed, suddenly, a message popped up on his phone.
Her name on WeChat is Huang Rujuan, and her profile picture is that of a very beautiful beauty, leaning against the front of a Maybach. She looks about thirty years old, but her first impression is that she looks a bit mean.
The content on WeChat read: "Detective Qin, have you found the evidence that my husband cheated on me when I asked you to investigate? You haven't heard from you for two or three days."
Qin Nan scratched his head with some confusion. He looked through the previous chat history and couldn't help but feel familiar when he saw the pictures he had sent her before.
He looked at it for a while before he remembered. He quickly opened the black Puma satchel and took out the photos inside. After comparing them, he found that they were exactly the same as the photos sent to women on WeChat.
After reading the previous WeChat chat records, I realized that the man’s name is Guo Liang, he is the owner of a company, and Huang Rujuan is his wife.
His wife discovered that Guo Liang was suspected of cheating. After investigation, it was found that Guo Liang had indeed cheated. What surprised people was that there were more than one.
Later, this woman named Huang Rujuan asked Qin Nan to find relevant evidence. So far, Qin Nan has only sent her a few pictures without explaining the reasons, so he sent such an inquiry message.
Qin Nan thought for a while and replied: "Sorry, there are a lot of things these two days. I will sort out the information for you tomorrow."
Then the other party sent an OK gesture, and then nothing more happened.
Qin Nan actually didn't want to pay attention to these things. He didn't want to do the things of private detectives secretly filming and following people. But when he saw Huang Rujuan mentioned the reward of 20,000 yuan at the beginning of the chat record, he was a little moved.
Moreover, Guo Liang has almost sorted out these photos. He only needs to hand them over to her, and then he can collect the money.
Qin Nan smiled when he saw these photos, then fell on the bed and fell asleep.
The next morning, Qin Nan came to the police station again. Song Yi was also at the door holding a thermos cup and drinking health tea.
After seeing Qin Nan coming, she hurriedly welcomed him into her office with a smile. At this time, Ma Xiaotao was also sitting on the sofa in Song Yi's office. Li Bing was sitting next to Ma Xiaotao with a stack of reports in his hand.
Ma Xiaotao just looked at Qin Nan when he came in, and then sat upright and looked at Song Yi's desk, seemingly unable to see him. Li Bing also smiled and said hello when he saw Qin Nan come in.
"Sit anywhere you want," Song Yi said, and then sat in his seat.
"Old Song, aren't you having a meeting? Why are there only a few of us?" Qin Nan asked with some confusion.
"You are not from our police station. Why are we asking you to hold a meeting to obtain information?" Ma Xiaotao looked at Qin Nan with disgust and said.
After just one night, Ma Xiaotao's character seemed to have returned to a few days ago, and she seemed to have figured out some things. Now, no matter whether it is Xiao Lu or Ma Xiaolu, as long as she finds the person, everything will be revealed.
"Hey, what did Xiaotao say?" Song Yi greeted.
"Old Qin, we plan to close the case regarding Zhao Liang's death, but we still need to investigate the second murder case," Song Yi said.
"Is the case closed?" Qin Nan said to Song Yi with wide eyes, and then Qin Nan sighed with relief and continued:
"Yeah, I didn't expect that the first murder case also involved other cases, which also involved many people..."
At this time, Qin Nan suddenly thought of the letter he received at the door that day, asking him not to participate in this case. Could it be that he was referring to the human organ trafficking organization?
Qin Nan frowned. After Song Yi saw Qin Nan's appearance at this time, he asked with some confusion: "What's wrong? Do you have any other questions?"
…
[Author's digression]: On the evening of November 24, there was a letter from a strange woman on WeChat.
On November 25, it was decided to close Zhao Liang’s case.
