"But the strange thing is, looking at Cao Keya's parents' house, although it's a three-bedroom apartment in a good location, it's an old house. It's from the time when T City hadn't developed much and the location wasn't that expensive, it was a house allocated to them by their employer. According to our investigation, Cao Keya's parents don't have any other properties other than that one. "
"According to Cao Keya's mother, the neighbors are saying that their area is going to be demolished, so the Cao family is now waiting for the demolition fee. They can buy at least two new houses in another place. According to this situation, the Cao Family was not considered a wealthy family. Her father was an ordinary employee of the highway section, and her mother had already retired. Her pension was not much, only 2,500 dollars a month. Her family's financial situation was not very good. But Cao Keya can live in a house with three bedrooms and two living rooms, and the neighborhood she lives in is in a good location, belonging to the middle and high-end residential area. "
From the bathtub where the body was found, Qi Youxuan knew that Cao Keya's house was not small.
"You can look into her personal relationships, such as her love life. Just like the first victim, Xiong Shi Shi. Although her family conditions were ordinary, she found a lover outside to improve her life. "
Yang Shaoqun, Wei Muran, and Yang Shaozhan, who were in the same office, twitched their mouths at the same time.
To improve their lives …
What an accurate and subtle description.
"Comparing the methods of the two victims, we can conclude that the murderer is the same person, but the murderer's methods are more advanced," Qi Youxuan said.
Over the phone, Yang Shaoqun seemed relieved. "Actually, I also hope that the murderer is the same person. Although serial killers are abominable, at least they only have one target. There was no need to work at both ends. I'm relieved to hear you say that. "
"Yes." Qi Youxuan agreed with this point. "Usually, the probability of two murders occurring in such a short period of time is relatively low. Although the second case was upgraded, the modus operandi was the same, and it was done by the same killer. It's like an old building. It's still the same steel and cement, but the walls are old. You can repaint it and paint some nice paintings to make it look more advanced, but the inside won't change. "
"Then why did you think of Cao Keya's personal relationship first?" Yang Shaoqun asked.
He trusted Qi Youxuan's judgment a hundred percent. He was especially blind. The reason why he asked this question was because he wanted to absorb more and learn more. It would be beneficial for him to handle cases in the future.
"Does Xiong Shishi and Cao Keya know each other? Is there any connection between the two of them? "Qi Youxuan asked instead of answering.
"No," Yang Shaoqun said.
"Two unrelated people were killed by the same murderer. If both of them were not related to the murderer at the same time, then the murderer must have killed both of them for the same reason. The three of them did not actually know each other, but the two of them happened to be within the scope of the murderer's reasons for killing. As a serial killer, he would stick to one or a few reasons when he kills, and the victims all fit his criteria. Some simply kill people who wear a certain color or style of clothing, some kill people who are similar to a certain person, some kill people who have a certain habit, and so on. "Qi Youxuan said.
"Cao Keya's family background is ordinary, and she's a nurse. Her salary isn't high, and she can't afford to buy or rent the house she's living in now. That's why I said that we should start investigating her private life. Is she the same as Xiong Shishi, having an ambiguous relationship with a man? You can check whose name her house is under, or who rented it for her. "Qi Youxuan said.
Yang Shaoqun was like a surging river on the phone, constantly expressing his admiration for Qi Youxuan.
Of course, Qi Youxuan couldn't say that in addition to his analysis, he could be so sure because the third case in "Murder Heart" was also a serial murder case. Although the motive of the murder was different, the murderer was also looking for the target for a fixed reason.
With just this analysis, he could imagine that the reason why Xiong Shishi and Cao Keya were killed was probably because they were doing favors outside.
However, he was afraid that Yang Shaoqun wouldn't believe it if he rashly linked this book with the case.
"Have you read a novel called" Murder Heart "?" Qi Youxuan asked.
Yang Shaoqun was a little dumbfounded. He felt that he couldn't keep up with Qi Youxuan's jumping thinking.
Could this be the legendary difference in IQ?
"No, what's wrong?" Yang Shaoqun asked inexplicably.
"That book will help you with the case. Take a look," Qi Youxuan said. He felt that he wasn't fooling Yang Shaoqun.
If there were no accidents, these three cases were all related to this book. Yang Shaoqun was currently working on a case, so reading this book would indeed help him. At the same time, he could also understand the contents of this book in advance.
After he read the book, he would tell him about the connection between "Murder Heart" and these three cases. He should be able to accept it more easily.
Although they didn't spend much time together, Qi Youxuan felt that this Captain Yang's ability to accept things was still very strong.
Yang Shaoqun's first reaction was, "Is this a necessary reading for criminology?"
"…" Qi Youxuan began to be curious about whether Yang Shaoqun had become the captain based on his strong imagination. "Anyway, you'll know when you read it."
"That …" Yang Shaoqun said embarrassedly, "Then, Mr. Qi, can you come over and help?"
"I'll go over as soon as possible," Qi Youxuan said. He planned to see if Jiang Yuecheng could apply to cooperate with T City on the case. If not, he would go over himself.
Now that things had come to this, his own interest in this case had been piqued.
Initially, he studied criminal psychology for Wei Muran, but as he learned, he also fell in love with this field of study. Although he focused on acting cute when he was young, he had the excellent genes of the Qi family, so his high IQ was still very shocking.
He learned everything quickly, so he didn't have much interest in learning anything.
He enjoyed working at Qi Lin, where he would face difficult problems one after another. Based on his own ideas and knowledge, he would be able to develop more new technological products. He would also be able to upgrade the products every year, adding new functions and innovations into the products.
However, he also liked solving these kinds of headache-inducing cases. It was like solving riddles, and he never got tired of it. When he was working a case, he was highly focused. When the case was solved, he would feel relieved and satisfied at the same time.
Therefore, the more he interacted with them, the more Qi Youxuan was willing to participate and help solve cases. He completely treated these as challenges to enrich his mental energy.
Yang Shaoqun couldn't believe that Qi Youxuan actually agreed. He was so excited that he stuttered, "R-r-r-r-really? I-I-I-Mr. Qi … "
"Calm down," Qi Youxuan said hurriedly. He repeated it a few times before Yang Shaoqun regained his composure.
"Sigh, I'll stop talking. I … I'll go and collect all kinds of information and testimonies. When the Almighty comes, I'll give them to you. Let's solve the case immediately!" Yang Shaoqun said and hung up.
Qi Youxuan looked at his phone silently. Yang Shaoqun's thoughts were also very jumpy. In the blink of an eye, he had jumped from Mr. Qi to the Almighty.
…
Meanwhile, Jiang Yuecheng was in the bureau chief's office, applying to go to T City to solve a case together. The bureau chief pondered for a long time. From his expression, he seemed to be in a difficult position and didn't quite agree.
"Yuecheng, what do you want me to say? This isn't something I can decide alone. I have to discuss it with the people in T City and get their approval. But what reason do you want me to use? Take out the novel you were talking about. They won't believe such a ridiculous story. "The bureau chief shook his head and said.
"Moreover, judging the nature of this case with just a novel and going to someone else's territory to interfere with their case, isn't this a little inappropriate? It's too childish! "
"Bureau chief, I've explained it to you in detail just now. The facts are right there," Jiang Yuecheng said patiently. "Once is a coincidence, twice is a coincidence, but what about the third time? Apart from the different motives, the means of committing the crime and the results of each case are the same. Or do you think that the three murderers just happened to read this book and arranged to line up to reverse the case according to the order of the book? You learn the first one, I learn the second, and he learns the third? "
The bureau chief's expression didn't look too good. Jiang Yuecheng's words were too sarcastic.
"The third case hasn't been confirmed yet, right?" the bureau chief said.
"It'll be too late if it's confirmed. If the third case is exactly the same as described in the book, will you believe it? But even if you believe it, it'll be too late. How are we going to find the murderer behind all this? Then we'll be too passive. Do we need to wait for the fourth serial murder case to come out before we start investigating again? This is a rare opportunity. Before more people die, we need to find the person behind the scenes, so that more people won't be sacrificed. "
