Wu Yu said: "Thanks to you today, otherwise we wouldn't have such a big harvest."
Feng Yan said: "It's nothing. Even if Xu Jiayan didn't reveal Zhou Yang's mental illness to us, we would check whether he has a history of mental illness, because this is the only place for breakthrough and the only way to explain Zhou Yang's mental illness. The possibility of his killing is not a perfect crime, it's just that some key information has not been found."
At around 8 o'clock in the evening, Wu Yu did not send the information to Feng Yan, but chose to bring the information to the hospital to find Feng Yan.
Wu Yu came to Liu Zheng and said that this case made him very frustrated and he couldn't sleep at night. He wanted to bring the information to Feng Yan, so he happened to talk to him about the case in person.
It happened that Liu Zheng was also on duty at night, so the three of them simply went to the reception room of the hospital, got some coffee and food, and began to discuss the case.
Liu Zheng is also a psychology expert. Although he does not specialize in criminal psychology like Wu Yu, he can still express his own opinions. The most important thing is that he has to be there to watch Feng Yan. It will definitely not work if he and Wu Yu are alone.
Wu Yu didn't show any concern. He brought several sets of information over in advance and asked Liu Zheng to take a look at it. He said that he was a psychology expert and a master in the field. He might have some unique insights. Let's discuss it together and maybe he could shed some light on the case. helpful.
I have to say that Wu Yu was really serious. Although this was a case that was almost judged to be an accident, Wu Yu still investigated most of Cheng Fei and Zhou Yang's family members, relatives and friends, and recorded their confessions in great detail. Knowing that letting his subordinates handle such a case would likely lead to negative work, he collected most of these confessions and information himself.
Feng Yan glanced at ten lines, and quickly read all the information, and began to meditate. After he finished thinking, Liu Zheng also finished reading.
Liu Zheng: "It seems that this case is indeed very difficult. The two suspects, Cheng Fei and Xu Jiayan, have perfect alibi. Zhou Yang was involved in a car accident at about 9:30 in the morning on December 10, and his family's The community parking lot surveillance showed that he left the community at 8:10 and entered the expressway toll station at 8:50. Both the community surveillance and the toll station surveillance captured his face and car. There is no dispute about the time of death.
And Cheng Fei left for school at 7 o'clock, arrived at the school at 7:30, the janitor testified, and then spent the whole morning preparing lessons in the office, went to the toilet twice, and came back in 5 minutes. The teacher who had no classes in the school office All of them can testify that they did not leave until around 10 noon when they were notified to go to the hospital to identify someone.
As for another suspect, Xu Jiayan, she started live broadcasting at 8 o'clock in the morning, ended the broadcast at 11 o'clock, and then went out to buy lunch. Many fans testified about this series of processes, and the live broadcast platform also has information about her login time. Yes, the doorman also confirmed that she left the door after 11 o'clock.
There was nothing wrong with the condition of Zhou Yang's car, no manipulation had been done, and no abnormalities were found during the autopsy on the body. "
Feng Yan snapped his fingers and said, "Glasses, I admire you. The mistress is indeed suspicious. Maybe she couldn't stand Zhou Yang's torture and chose to kill him."
Wu Yu said with a headache: "This is an impossible crime. If it weren't for the wrong insurance time purchased by Cheng Fei, this would have been an accident. It was just that Zhou Yang died in a car accident while driving due to fatigue. In fact, just because Zhou Yang left the community alone and From the evidence on the highway, we can basically conclude that these two people have no chance or suspicion of murder. The deceased at the scene of the crime did not have any special injuries from the attack. The autopsy showed no signs of chronic or acute poisoning. The car was in good condition. The deceased was in good health and had no heart. Diseases and other diseases. Our investigation of Cheng Fei and Xu Jiayan can only clear them of suspicion."
Feng Yan tapped the table with his index finger and said, "No, the deceased was sick."
Wu Yu frowned and said, "You mean mental illness? Could this be fatal in an instant?"
Feng Yan glanced at Liu Zheng and motioned for him to answer this question.
Liu Zheng said: "Patients with mental illness, if they are strongly suggested or receive some strong stimulation directed at their mental illness in an instant, are likely to lose control briefly and instantaneously. And on the highway, this kind of loss of control is very serious. deadly."
Feng Yan asked: "What was Wu Yu's speed at that time?"
Wu Yu replied: "According to the survey, it is about 120 kilometers per hour."
Feng Yan nodded: "In other words, he was driving almost against the speed limit. It's no wonder. If there is some psychological stimulation and suggestion at this time, once he loses control, the probability of death is extremely high."
Liu Zheng added: "During the period before Zhou Yang's car accident, were there any phone records, or did his or other chat software receive some pictures, voices or videos?"
Before asking this question, Liu Zheng already had a feeling that the clouds were clearing. This was the only point that could be broken through. It should be the key to the murderer's killing methods. As long as it was found out whether anyone passed this point in the period before Zhou Yang's car accident. If you use similar methods to stimulate Zhou Yang, you can basically lock in the scope of the murderer.
What surprised him was that Wu Yu shook his head regretfully and said: "From the time Zhou Yang left home until his death in the car accident, he did not receive a single call, text message, WeChat, or any other personal information transmission record."
"What?" Liu Zheng's eyes widened in surprise.
Feng Yan smiled and said, "It's a bit interesting."
Wu Yu asked unwillingly: "Could it be that Zhou Yang received this kind of information the day before, only remembered it the next day, and then lost control and caused a car accident?"
Liu Zheng: "This is impossible. First of all, Zhou Yang is not a mental patient. I have seen his medical records very clearly. He just has some violent tendencies, and he is not targeting the general public. He is not harmful to society for the time being, otherwise the psychiatrist would not let him go. He left. No, it should be said that if Zhou Yang really had a serious mental disorder and reached the point of endangering society, he would not come for treatment at all. Real patients generally do not think that they are sick, just like Feng Yan. Are you sick?"
"You are the one who is sick."
Liu Zheng: "Let's see."
…
Wu Yu's face twitched, and he thought to himself: Why do the two of them feel like they have some mental problems, are they just kidding?
Liu Zheng continued: "So, it is impossible for patients like Zhou Yang to carry the emotions from the first day to the next day. In fact, the example I just listed is already very extreme. He received the order in a short period of time. It is almost impossible for such a situation to happen, unless a very skilled psychologist has specially customized a murder plan based on the details of his illness, such as finding something that can trigger his psychological trauma. You must listen to or watch the language, text, pictures or videos for him, and you must ensure that he can listen or watch it on the highway, so that there is a chance that he will lose control and cause a car accident.
I have just emphasized that it is instantaneous. Patients like Zhou Yang cannot be troubled by a psychological suggestion for a long time, so the guidance or suggestion must be induced in a short period of time to be successful. "
Wu Yu said helplessly: "It seems that the only breakthrough point is gone again. Is it really an accident?"
Looking at Wu Yu who was about to give up on himself, Feng Yan stretched out his index finger and said, "Don't be discouraged. Although this case has an unexpected halo and even an unsolvable situation, Cheng Fei bought the one after Zhou Yang's derailment and before the accident. "Death insurance" is indeed an indisputable fact. If she was really responsible for killing Zhou Yang, I think she is too crazy."
