There were some words written on it and some pictures drawn on it. Together with the case information that Guo Yue had told her before, Nangong Yiyi knew that what Ai Fan meant on the whiteboard was to focus on searching residential areas and factory dormitories on both sides of the river.
"Why focus on the two sides of the river? Is it just because the body... was found on the riverside?"
Ivan's hand holding the chopsticks paused slightly, and Nangong Yiyi realized that she shouldn't make the case now. After all, this case was really serious, and Ivan was still eating.
Ivan didn't seem to care at all. He took a sip of water and said: "Yes, the principle of proximity, but there is another point. There are two possibilities for killing people and dismembering their bodies. One is to vent anger, and the other is to prevent people from knowing who the deceased is. Now We cannot confirm the identity of the deceased, so the first point can only be put aside for the time being, and the second point... "
As Ivan spoke, he pointed at one of the photos of the riverside environment during the day and continued: "This place is located at the junction of the two cities. It is mostly surrounded by factories and is relatively desolate. If the murderer did not deliberately want people to not know who the deceased is, Who, then he only needs to discard the deceased in the river. With the current flow of the river, even if it flows slowly, the impact of the river will not leave any fingerprint evidence of the murderer, etc. So why does he use such a complicated method? "
Nangong Yiyi listened to Ivan's words quietly. She didn't know when it started. As soon as Ifan analyzed the case with her, Nangong Yiyi's mind automatically switched to the student's thinking mode.
"You mean, because we don't know the identity of the deceased now, we can't start from her social relations for the time being. And if it's because of the second point, it's probably the second point. He doesn't want people to know who the deceased is. , but... it’s not right either?”
Nangong Yiyi felt that her mind was a little confused and she couldn't figure out her thoughts for a while.
Ivan smiled slightly and continued: "Assuming that the murderer dismembered the body because he did not want people to know who the deceased was, then there is a problem. There are many ways to prevent people from knowing who the deceased was, such as cutting off the head, such as disfigurement , but if this person is familiar to people around her, just beheading and disfiguring can still make people recognize who she is, so the murderer chose such an extreme method."
Nangong Yiyi frowned when she heard this. She still didn't understand, but she seemed to vaguely understand something.
"No, what I mean is that the situations you mentioned have nothing to do with the victim living by the river."
Ivan reached out and knocked Nangong Yiyi on the head: "You're so stupid, listen!"
Nangong Yiyi rubbed the place where she was knocked. He disliked her again.
"When a body enters the river, there is no way of knowing where it will float, and the possibility of being washed ashore by the river is also very high. If a body appears on the riverside, the police will immediately investigate the identity of the deceased and the people living on both sides of the river. If the deceased is not among these people, then the question 'who is she' will be postponed, but if so, then the question 'who is she' can be answered quickly. Reverse reasoning, precisely because this person is in Among these people, if the murderer doesn’t want people to know who she is, or delay the time of knowing her identity, then he needs to dismember her body.”
There was a sarcastic smile in Ivan's eyes again, and Nangong Yiyi knew that this was his contempt for the murderer.
