Liu Zheng continued, "That's unlikely, if it's hypnosis, you have to have a hypnotist on the scene, and the triggering conditions are quite harsh." ”

Feng Yan thought for a while and said, "The movie that was more popular some time ago is called "Escape from Desperate Town", you have also watched it. ”

Liu Zheng hummed, "Look, what do you mean is that the deceased may have heard a certain sound or music, which was set by the hypnotist early in the morning, and it was emitted through the stereo in the car after Zhou Yang got on the bridge, or it was triggered by the ringtone of the caller, right?" ”

Xiao Guo interjected, "Your analysis is so in-depth and thorough, I feel infinitely close to the real murderer's murder method, but I want to remind you that the deceased has not received audio or video on his mobile phone from the time he left the house until the accident." The situation of the audio in the car is also impossible, and there is no CD in the deceased's car, and there is no playback source such as a USB flash drive. ”

Feng Yan turned around and continued to look at the photo, and said, "At present, it is known that the murderer's method of killing is linked to time, and the scope has narrowed down a lot, so let's check it slowly." By the way, after the car was recovered, were any of the deceased's personal belongings found in the car? For example, mobile phones and the like, according to our analysis, locate the alarm ringtone of the mobile phone, maybe the deceased was set to set an alarm clock to ring regularly. Let's see if it's weird, if the high-end hypnotist of the old witch type in "Escape from Desperate Town" makes a move, it is not ruled out that Zhou Yang will fall asleep, but I guess the phone should be flooded and can't be turned on. ”

Xiao Guo: "The deceased's belongings are all there, and the mobile phone can be turned on after we repair it." However, the relics of the deceased are temporarily stored in another warehouse, and the colleague who takes care of the warehouse has something to do at home, and he will not be able to come to work until tomorrow. ”

Feng Yan nodded and said to Liu Zheng, "Let's go back, contact Wu Yu in the evening, and ask how they were doing at the afternoon meeting and how to deploy next." ”

On the way back, Liu Zheng asked Feng Yan, "Your reasoning just now feels very reliable, but why is your reaction so calm." ”

Feng Yan looked at the sky and said, "I feel that the probability of Zhou Yang being knocked down by hypnosis and falling into the river is too small, how could there be such a powerful hypnotist to kill this kid, hired by Cheng Fei?" It's unlikely, but it can't be ruled out, so check if this kid has been set an alarm clock and what the alarm clock ringtone is. ”

At about 7 o'clock in the evening, Wu Yu contacted Liu Zheng, and just after the meeting ended, he roughly talked about the next deployment and the discussion of the meeting.

At the meeting, Wu Yu reported the harvest of these two days, after the inconsistencies in the fake video to buy insurance, and Wu Yu's statement of the real murderer's intention to play the police's point of view, the bureau was finally furious, the director ordered Wu Yu to solve the case within a week, the statute of limitations is the same as before, and now there are 4 days left (Wu Yu and Li Gang have already passed 1 day when they came), but a lot of manpower was sent to him, and a task force was set up, and Li Gang was ordered to be the team leader, Wu Yu was the deputy team leader, and the real murderer must be caught, It is necessary to get complete ironclad evidence that the murderer killed.

The specific deployment is to focus on checking Cheng Fei's interpersonal relationships, detailing 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, for Fan Qihao, who is also very suspicious, the police will also investigate in the same way as Cheng Fei's investigation. According to the preliminary investigation, Fan Qihao is in Shanghai, and the local police will cooperate with the police in Shanghai to summon Fan Qihao for questioning.

"Doctor Liu, tomorrow I will go to Cheng Fei's high school to investigate, and when the time comes, I will bring Feng Yan, and we will be together."

Liu Zheng told Wu Yu about the situation when he went to the bureau to check the information in the afternoon and the results of Feng Yan's analysis, Wu Yu felt that Feng Yan's analysis was very good, and recorded these while listening to Liu Zheng.

Early the next morning, Wu Yu came to the hospital to pick up the two of them, and the three of them drove to the bureau first, Feng Yan meant to determine whether Zhou Yang's mobile phone alarm clock constituted a hypnotized situation.

The three of them came to the warehouse dedicated to this kind of evidence, Zhou Yang's mobile phone card had been removed, but this did not prevent him from finding the ringtone of the alarm clock, Zhou Yang was an Apple mobile phone, and he would know it by looking at it after entering the settings.

After checking, the alarm ringtone set by Zhou Yang's mobile phone is the default ringtone of the mobile phone, and there is no alarm clock set between 8 o'clock and 10 o'clock, there is only an alarm clock that will never be repeated, which is the one that woke Zhou Yang up that day.

"Let's go, it seems that there are really no very powerful hypnotists."

Liu Zheng half-jokingly reminded Feng Yan that it was time to leave.

And Feng Yan still held Zhou Yang's mobile phone in his hand, scanned the screen left and right with his thumb, and kept switching the main interface, as if thinking about something, Wu Yu signaled Liu Zheng not to speak, wait first.

Zhou Yang's mobile phone is Apple X, face recognition, this generation canceled the ho key, after Feng Yan stopped scanning the screen, he thought for 1 second, tried to scan it from the bottom of the screen with his thumb, and suddenly the apps running in the background appeared, Feng Yan found that there were a lot of apps in it, it seems that Zhou Yang usually does not like to clean up the background APP.

Feng Yan raised the phone and said, "This mobile phone, from salvage to repair, should have been opened by someone, and the information software in the mobile phone should have been flipped." ”

Wu Yu: "That's naturally there, otherwise how would we know that no one called or messaged Zhou Yang on the day of his accident." However, we all have to look at such important evidence in this warehouse, and the whole process of viewing must be carried out under the camera. ”

Feng Yan looked up and looked around, and found that there was a camera above his head in the position where he was standing, and he immediately pointed at this camera and said to Wu Yu, "This kind of thing? ”

Wu Yu replied, "Yes, all the cameras in this and the warehouse are in a 7x24 hour normal operation state, so as to monitor the status of the warehouse and all the actions of the staff during the period when they take the evidence." ”

Feng Yan snapped his fingers and said, "That's great, that is, the process of checking your phone should have been recorded by the camera, right?" ”

Wu Yu nodded, "Yes, that's also a must." ”

Feng Yan: "How many times have you checked your phone?" ”

Wu Yu: "So far, it's only 1 time, and I checked it. ”

Feng Yan pointed to the camera above his head and said, "Then I want to watch the video footage of the time you checked your phone." ”

Liu Zheng asked, "What are you going to do?" ”

Feng Yan smiled lightly and said, "I thought of a very interesting possibility, let's watch the video first." ”

After the video was called up, it showed that Wu Yu turned on the mobile phone under the lens, he first opened WeChat and looked at it, then opened the call record and looked at it, and then looked at the text message, basically switched between these three functions, and finally turned off the mobile phone and put it back in its original place.

After reading it, Feng Yan turned on Zhou Yang's mobile phone again, looked at it, nodded and said, "So that's really the case." ”
