After listening to Lin Yuhan's analysis, Wu Hao was quite puzzled.

"Then why did he do it?"

Lin Yuhan pondered for a long time and spit out five words: "Self-guilty paranoia." ”

"What do you mean?"

Lin Yuhan explained: "This is the second of the five special types of paranoia, self-guilty delusions, also known as evil delusions. The patient has no basis for believing that he has committed serious mistakes and crimes, or even that he is guilty of a heinous crime and a deserving death, and should be punished, so much so that he refuses to eat or asks for labor reform to atone for his sins. It is mainly seen in depressive episodes of affective psychotic disorders, but can also be seen in other psychiatric disorders such as schizophrenia. I think Chen Xi may have been stimulated because he grew up in a single-parent family and his mother died of illness, which led to a sense of revenge against this society, which induced delusions of self-guilt. ”

"Hmph~ interesting...... Wu Hao sneered, "Detective Lin means that the crimes confessed by Chen Xi came from his imagination?" ”

Lin Yuhan nodded: "You can also understand it like this." I suspect he has serious homicidal fantasies. That is, due to long-term mental depression or hyperactivity, the desire to kill someone arises. If he can't do these thoughts in real life, in order to seek psychological comfort, he will fantasize about how to kill or hurt someone, and over time it will become a psychological habit, so he shows an extremely rebellious antisocial personality. ”

Seeing Wu Hao's appearance of not understanding, Lin Yuhan explained: "For a simple example, in life, you will meet some people who you particularly hate or bully you, but you can't do anything with him, you will have an obsession in your heart, want to kill him, or expect him to be killed by a car while walking on the road, and constantly simulate various scenarios of him being killed in your mind, which is a murder fantasy." To be honest, I used to have strong thoughts about this, and the object of my fantasies was standing in front of me at this moment. ”

Wu Hao's pupils suddenly dilated, his whole body trembled unconsciously, and he shouted: "You are neurotic!" ”

Obviously, he was taken aback by Lin Yuhan's later statement, Lin Yuhan stopped teasing him, took out all the photos of Chen Xi's family, and analyzed them one by one: "You see, some of these photos have been painted with red crosses, and some have not. Usually, a red cross is drawn to mean killing someone. And in reality, in real life these people are not dead. Therefore, we can make such a view that Chen Xi regarded the cats and dogs as these women in the photos, mutilated them, and simulated and practiced the murderous fantasy in his heart, thus inducing the paranoia of self-guilt. ”

At this point, Lin Yuhan did not continue, and Wu Hao next to him was already dumbfounded.

After a long while, he swallowed his saliva and said quite unconvinced: "Then can you explain to me why Chen Xi happened to be at the crime scene on the night of the crime, and can clearly describe the whole process of killing Li Yue?" ”

"There is a possibility......" Lin Yuhan analyzed, "he witnessed the murderer's killing of Li Yue, and imagined that person as himself." Because the murderer did for him what he always wanted to do but didn't have the courage to do. In this way, he obtains great psychological satisfaction. ”

"Do you have proof?"

Lin Yuhan didn't answer him directly, but said, "I ask for a separate inquiry about Chen Xi. ”

"Why do you think I can promise you?"

"You will." The corners of Lin Yuhan's mouth outlined a confident smile.

Obviously, these two vicious murder cases have gone through so many days, and no matter whether Lin Yuhan's analysis is right or wrong, Wu Hao doesn't want any mistakes in the middle.

If Chen Xi is acquitted again, it means that the efforts of the past few days have been wasted.

At this moment, Chen Mengnan hurried over and said to Wu Hao: "Senior brother, it's not right. ”

"What's wrong?" A sense of foreboding arose.

Chen Mengnan opened the report: "Chen Xi's DNA and fingerprints do not match those found at the two crime scenes, and the shoe prints do not match." ”

"What, how is this possible!"

Wu Hao's heart sank, could it be that everything was really as Lin Yuhan said. This, this is impossible, he has obviously confessed his guilt, how can he not be a murderer!

"That's true, and ......" Chen Mengnan's face also showed a complicated look, "The blood samples taken at his home are all animal blood, and there are no traces of human blood. ”

Wu Hao leaned against the wall in a daze, stunned.

Although unwilling to accept it, the implementation is in sight.

In this way, to a large extent, Chen Xi is not a murderer.

Chen Mengnan asked, "Senior brother, what should I do now?" ”

Wu Hao was silent for a long time, sighed heavily, and said faintly: "Take him to the reception room!" ”

Then he turned around and silently patted Lin Yuhan on the shoulder.

Helplessness and despair may be his mood at this time.

And this kind of mood may only be understood by Lin Yuhan.

Lin Yuhan walked into the reception room and saw Chen Xi sitting in it with a spring face. His expression was relaxed, and it was a relief. He finally got his wish and became a "murderer" while waiting to receive justice.

And in the relaxed expression, there is a trace of nervousness and expectation.

Lin Yuhan closed the door of the reception room and said, "I'll ask you a few questions." ”

Chen Xi glanced at Lin Yuhan and didn't speak, but his expression changed significantly.

Lin Yuhan dragged a stool and sat in front of him. "Rest assured, there are no police here, and there is no surveillance." He asked in a calm tone, "I hope we can be honest with each other." ”

There was a bohemian sneer on the corner of Chen Xi's mouth: "I said that I have already confessed to the murder, sir, aren't you still honest?" ”

"First of all, let me repeat, I'm not a cop." Lin Yuhan shook his head, "And, I don't think you killed someone, you're just a cowardly speculator." ”

Lin Yuhan wanted to stimulate Chen Xi in this way to see if he had any weak reactions.

Sure enough, Chen Xi instantly became nervous, his whole body trembled violently, his face turned red, and he roared loudly: "I killed them, they were all killed by me, this is their retribution!" I'm going to kill more people, kill them all!" ”

"Then ......" Lin Yuhan suddenly asked in a low voice, "You also killed Wu Dandan?" ”

"What!" Chen Xi raised his head violently, as if he had been poked at the pain point, and his eyes showed a surprised expression, "No, no, I didn't kill her." She, she's ......"
