"There is one of the psychological profiles that Xiao Nan made to the murderer before, that is, the murderer has obsessive-compulsive disorder, and the room where he lives is absolutely not allowed to have any untidy places, but Xiao Nan found two books of the same set on his bookshelf in Wei Yiche's room that were not put together. It occurred to me that I had overlooked something very important. Li Chengfeng said.

"What was overlooked?"

"Wei Yiche told us that he had been away on a business trip for a month and had not been home for a long time, and it was not ruled out that someone had come into his room to borrow this book during his business trip, but when he put it back, he didn't put them in the same place."

"After you say this, I remember that Xiao Nan and I went to Wei Yiche's house outside two days ago, and all the items in the house were neatly arranged, so clean that I didn't even see the dog's hair, and it must have been cleaned very carefully." Fang Xinling recalled.

"Looks like I'm not wrong in my speculation."

"And how do you explain the second and third points you just raised?"

"Before, my colleagues in the big crime squadron and I always thought that there was only one murderer who caused this case, but now it seems that we are stuck in a fixed state of mind, this case is likely to be completed by two people, Wei Yiche did not have an alibi during the crime, but he was able to enter the crime scene after their deaths, and there were more than ten hours from the time of the crime to the next day, and he had plenty of time to complete all this." Li Chengfeng analyzed.

"But there is one thing that I think is very strange, although during this interval, Wei Yiche can drive into the Wei family villa openly, but he will definitely not be able to escape the surveillance and your investigation, and it is such a sensitive time, if he really does this, it is impossible for you not to notice! How did he come in without you noticing? Fang Xinling said with a serious expression.

"You're right, we did check the list of all the foreign visitors in those two days from the Chaobaihe Villa District Security Office, and we also checked the surveillance video before and after the crime, and we did not find that Wei Yiche had entered the Wei Villa. And we asked the security department why they put the murderer's car in that day, and the answer given by the security department was that they had seen the car enter and leave the Chaobaihe villa area more than once, so I would let it go easily, so I concluded that the murderer must have known the Wei family, so I changed the direction of the investigation to investigate Wei Dong's interpersonal relationships. Li Chengfeng nodded.

"Since just now, I have been thinking about the last words that Yun Yun threw at you before leaving, and I always feel that her words have another meaning, she should know something. What could make her so sure you can't catch the murderer? ”

"Chaobaihe Villa Area is a high-end residential area that Yunqi Real Estate focuses on developing!"

Fang Xinling and Li Chengfeng's eyes touched, and they immediately understood the deep meaning of his words.

"It seems that we really have to thank Yun Yun for providing us with such a valuable clue." Fang Xinling smiled as sly as a fox.

"Fang Xinling, you should have been suspicious of Wei Yiche a long time ago." What Li Chengfeng said was not a question sentence, but an affirmative sentence, and even the tone was so affirmative.

"You can see that." Fang Xinling deliberately showed a frustrated expression.

"Why?"

"I lost four of my most important relatives in one day, and the only one is still uncertain, and there is such a big company floating in the wind and rain, can you still clean the house? Can you still have the heart to tidy up your appearance? Words can deceive people, but people are always honest in their actions. ”

"You've learned about this?" Li Chengfeng's face was surprised.

"Well, I've read some books on this, my ex-boyfriend is also a criminal police captain like you, in order to enter his world, in order to have a common language with him, I also went to find his professional books to read, but what I didn't expect was that it really came in handy after he left me." Fang Xinling smiled bitterly.

"I see."

"What about you? When did you start to suspect Wei Yiche? ”

"From the first time I saw him, I felt that something was wrong."

"Why?"

"When he introduced himself to us that day, in addition to saying his name, the first sentence said that he was not a family member of the deceased, but the CEO of Huaxia Technology, from a psychological point of view, the position of the CEO of Huaxia Technology is more important than his identity as a descendant of the Wei family, do you say I can not doubt it?"

"It seems that Captain Li, like me, is a person who is very good at drawing inferences." Fang Xinling smiled.

Normally, Li Chengfeng would feel very disgusted when he heard something like this, but when he heard Fang Xinling say this, he didn't feel disgusted, and he was actually a little happy.

What kind of man would be willing to break up with such a woman? For the first time in his heart, he became interested in what he considered to be insignificant.

"Fang Xinling, with your keen insight, you are completely the material to be a policeman, why didn't you choose to be a policeman in the first place?"

Fang Xinling didn't expect Li Chengfeng to suddenly ask her such a question, and immediately felt a little overwhelmed, and looked at Li Chengfeng in surprise, because in Fang Xinling's impression, Li Chengfeng was a person who was cold to the bone, and it was basically impossible for him to take the initiative to care about others.

"When I filled in the volunteer after the college entrance examination, I didn't think about applying to the same school as Xiaonan, becoming a great people's policeman, eliminating evil, and starting my unknown and great life. But to tell you the truth, I'm not a person who sacrifices myself for everyone, I'm just a layman, I think being a police officer is too hard and tiring, and I can't always accompany my parents, and I will encounter all kinds of dangers when performing tasks, I don't want my parents to be afraid of me all day long, I just want to do what I like, it's enough to spend my life safely and happily, and there will definitely be a place to realize my value. Fang Xinling said with a complicated expression.

"Well, everyone has their own ambitions." Li Chengfeng responded.

"Li Chengfeng, from the perspective of criminal investigation, you pay attention to the motive of the crime in your investigation and handling of cases, if Wei Yiche is really the murderer, what do you think it will be? Why did he kill his loved ones so brutally? Fang Xinling asked.

"I don't see it at the moment." Li Chengfeng shook his head.

At this time, Li Chengfeng's phone suddenly rang, it was a call from Su Xiaonan.

As soon as he answered the phone, Li Chengfeng's face immediately turned cold.

"Li Chengfeng, what happened?"

"Zhou Changhong was killed."
