Liu Zheng continued, "That's unlikely. If it's really hypnosis, the hypnotist would have to be on site, and the triggering conditions are quite stringent."
Feng Yan thought for a while and said, "You must have seen the popular movie some time ago called "Escape"."
Liu Zheng hummed, "Look, you mean that the deceased may have heard a certain sound or music. This sound or music was set by the hypnotist early in the morning and was emitted through the car speakers after Zhou Yang got on the bridge. Or it could trigger hypnosis through ringtones or something like that, right?"
Xiao Guo interjected, "Your analysis is so in-depth and thorough. I feel that it is infinitely close to the murder method of the real murderer. However, I would like to remind you that the deceased's mobile phone did not receive any audio or video from the time he left home until the accident. Video. The situation of the audio in the car is also impossible. There was no CD or USB disk or other playback source in the deceased’s car.”
Feng Yan turned around and continued to look at the photos and said, "It is known that the murderer's method of killing has been linked to the time. The scope has been narrowed a lot. Let's check slowly next. By the way, after the car was salvaged, were there any people in the car? Some personal belongings of the deceased were found in the room? For example, a mobile phone. According to our analysis, we can locate the alarm clock ringtone of the mobile phone. Maybe the deceased was set to have an alarm clock ringing at a scheduled time. Let's see if there is anything weird. In case it is If the old witch-type high-end hypnotist in "Get Out" takes action, it is not ruled out that Zhou Yang will fall asleep due to the trick, but I guess the phone may have been damaged by water and cannot be turned on."
Xiao Guo: "All the belongings of the deceased are there, and the mobile phone can be turned on after we repair it. However, these belongings of the deceased are temporarily stored in another warehouse. The colleague who is looking after the warehouse has something to do at home and will not be able to come to work tomorrow."
Feng Yan nodded and said to Liu Zheng, "Go back and contact Wu Yu tonight to ask how the afternoon meeting went and what the next step will be."
On the way back, Liu Zheng asked Feng Yan, "Your reasoning just now felt very reliable, but why was your reaction so calm?"
Feng Yan looked at the sky and said, "I feel that the probability of Zhou Yang being hypnotized and knocking over the guardrail and falling into the river is too small. How could such a powerful hypnotist come to kill this kid, hired by Cheng Fei? It's unlikely, but it's not possible either. This possibility has been ruled out, so let’s check whether this kid has an alarm clock set and what the alarm clock’s ringtone is.”
At about 7 o'clock in the evening, Wu Yu contacted Liu Zheng. Just after the meeting, he briefly talked about the next deployment and the discussion of the meeting.
At the meeting, Wu Yu reported all the gains of the past two days. After the irrefutable evidence of inconsistencies in the fake video to buy insurance, and Wu Yu's statement that the real murderer intended to trick the police, the bureau was finally furious. The director ordered Wu Yu to have to wait for a week. The case was solved within 10 days, and the statute of limitations was still the same as previously required. There were still 4 days left (one day had passed when Wu Yu and Li Gang arrived), but a lot of extra manpower was assigned to him, and a task force was set up to order Li Gang. As the team leader, Wu Yu, the deputy team leader, must catch the real murderer and obtain complete and irrefutable evidence of the murder.
The specific plan is to focus on investigating Cheng Fei's interpersonal relationships, including her classmates, friends, colleagues and relatives. Cheng Fei's hometown is in the county of Yunhai City, and people will also be sent to visit her hometown. In addition, the police will also investigate Fan Qihao, who is also highly suspected, in the same way as Cheng Fei. Preliminary investigation shows that Fan Qihao is in Shanghai. The local police will cooperate with the Shanghai police to summon Fan Qihao for questioning.
"Doctor Liu, I will go to Cheng Fei's high school to investigate tomorrow. Then I will bring Feng Yan with me. Let's go together."
Liu Zheng told Wu Yu what happened when he went to the bureau to check the information in the afternoon and Feng Yan's analysis results. Wu Yu felt that Feng Yan's analysis was very good, and he recorded it while listening to Liu Zheng's words.
Early the next morning, Wu Yu came to the hospital to pick up the two of them. The three of them drove to the hospital first. Feng Yan wanted to make sure that Zhou Yang's cell phone alarm clock did not constitute hypnosis.
The three of them came to the warehouse dedicated to storing such evidence. Zhou Yang's mobile phone sim card had been removed, but this did not prevent them from finding the ringtone of the alarm clock. Zhou Yang had an Apple phone and he could find out after entering the settings.
After checking, it was found that the alarm clock ringtone set on Zhou Yang's mobile phone was the default ringtone on the mobile phone, and there was no alarm clock set between 8 o'clock and 10 o'clock. There was only one alarm clock that never repeated, which was the one that woke Zhou Yang up that day.
"Let's go. It seems that there really aren't any very powerful hypnotists."
Liu Zheng half-jokingly reminded Feng Yan that it was time to leave.
Feng Yan, on the other hand, still held Zhou Yang's phone in his hand, swiping the screen left and right with his thumb, constantly switching the main interface, as if he was thinking about something, Wu Yu motioned to Liu Zheng not to speak, and to wait.
Zhou Yang's mobile phone is an Apple Appeared, Feng Yan found that there were many apps in it. It seemed that Zhou Yang did not like to clean up the background apps.
Feng Yan raised the phone and said, "This phone, from salvage to repair, should have been opened by someone and the information software in the phone has been flipped."
Wu Yu: "Of course there is, otherwise how would we know that no one called or sent messages to Zhou Yang on the day of his accident? But for such important evidence, we have to check it in this warehouse. The process of checking it The whole process has to be done under the camera.”
Feng Yan raised his head and looked around, and found that there was a camera above his head where he was standing. He immediately pointed at the camera and said to Wu Yu, "This kind of thing?"
Wu Yu replied, "Yes, this and all the cameras in the warehouse are in normal operation 24/7 to monitor the status of the warehouse and all the actions of the staff during the collection of evidence."
Feng Yan snapped his fingers and said, "That's great. In other words, the process of checking your mobile phones should have been recorded by the camera, right?"
Wu Yu nodded, "Yes, that is also necessary."
Feng Yan: “How many times have you checked your phone in total?”
Wu Yu: “So far, I checked it only once.”
Feng Yan pointed to the camera above his head and said, "Then I want to see the video of you checking your phone."
Liu Zheng asked, "What on earth are you going to do?"
Feng Yan smiled easily and said, "I thought of a very interesting possibility. Let's watch the video first."
After the video was retrieved, it was shown that Wu Yu opened his mobile phone under the camera. He first opened WeChat and looked at it, then opened the call history and looked at it, and then looked at the text messages, basically switching between these three functions. , and finally turned off the phone and put it back where it was.
After reading it, Feng Yan opened Zhou Yang's phone again, looked through it, nodded and said, "So that's really the case."
