Without waiting for a few people to ask, he spoke first, "The background app programs on Apple phones will not disappear after shutting down. Zhou Yang does not have the habit of closing background apps, even though these apps may not take up traffic. But as long as it is not artificially If you close it, it will remain there.
Yesterday I got some inspiration from Xiao Guo's words. Could Zhou Yang be hypnotized? We just confirmed his alarm clock ringtone, and I thought about it, this is unlikely. Since Zhou Yang had not received any phone calls or WeChat messages from the morning of the accident until the car overturned into the river, the only thing I could think of to set up ambush reminders at regular intervals was an alarm clock. It was just confirmed that there is nothing wrong with the alarm clock. But at that time, I actually thought of a possibility, what if the sound was played through a mobile phone? "
Liu Zheng said, "Are you referring to the music software built into the mobile phone connecting to the media in the car through Bluetooth to play music?"
Feng Yan nodded, "Yes, so I just checked Zhou Yang's phone. The background programs of Apple Just swipe up the page. The order of programs depends on the order in which the owner of the phone uses it. In other words, if Zhou Yang's background program shows that the music app is first, then it is almost certain that Zhou Yang was alive during his lifetime. The last app I used may be this music app, which connects to the car speakers via Bluetooth and plays music.
When I was checking Zhou Yang's mobile phone just now, I found that the order of the background programs was as follows: the first was phone records, and the second was Handsome Cat Music. Because I considered that some staff might look through Zhou Yang's mobile phone after his death, I confirmed it with Wu Yu. Through the video recording, it can be confirmed that the 123rd background program was checked by Wu Yu later. Now take a look at the order of the background programs on the mobile phone. The first one should be settings, the second one is the alarm clock, and then the third, fourth and fifth ones are the phone records, The bar is Handsome Cat Music, and the setting was the last one we checked just now, so it ranked first. "
After several people checked it, Feng Yan took the phone and said, "Now we can go to Handsome Cat Music and check the last song Zhou Yang listened to to see if there is anything weird."
Even after the music software is completely logged out, it can still record the last song listened to. When Feng Yan opened the software, she found that the last song Zhou Yang listened to before his death was a song called Evey Stay. This song is stored in a playlist, along with 12 songs, all in English. The name of this playlist is Music Therapy.
"Ha~ha~"
Feng Yan laughed stiffly, and Liu Zheng immediately dug out Zhou Yang's medical records from the bag he carried with him. He remembered very clearly that there was a song catalog for music therapy in the medical records at that time, and it was Zhou Yang. The mental hospital recommended songs to him to relieve his violent tendencies by listening to these music. The medical record at that time clearly stated that the time to listen to these songs should be between 8 and 10 in the morning for the best effect.
"The psychiatrist provided a total of 11 songs, but there was no song called Evey Stay."
Feng Yan crossed his arms and said, "That is to say, someone added a song to the playlist created by Zhou Yang for his own medical treatment. Let's listen to this song first."
evey stay starts to play. This is a piece of pure music with an unusually soothing melody. It is very comfortable to listen to and quite calming. The harmony of multiple instruments and the type of melody give off a strong hypnotic effect.
After listening for more than a minute, Feng Yan said with certainty, "I already know the complete process of how the murderer killed Zhou Yang."
"First of all, the murderer secretly added this song called evey stay to Zhou Yang's therapy playlist. Note that this song called evey stay is located at No. 8 on the playlist. The recommended time for listening to the song for therapy is 8 From 0 to 10 o'clock, Zhou Yang left the house at 8:10. The traffic conditions in the city were not very good. He might not have time to listen to music. So if he got on the highway and then turned on his mobile phone to connect to Bluetooth and started listening to music, this letter Each song in the playlist lasts more than 5 minutes. Zhou Yang got on the expressway at 8:50 and got on the bridge at 9:25. The time during this period was 35 minutes, and 7 songs have been played. , and the length of the entire bridge is 12 kilometers. If calculated at a speed of 120 kilometers per hour, it will take 6 minutes to go from the upper bridge to the lower bridge. When the deceased got on the bridge, the 8th song of the song list just started playing. song, which sounds a little listless to me, Evey Stay. The murderer accurately calculated Zhou Yang’s driving and listening habits, and started playing this song on the bridge that Zhou Yang must pass. It made Zhou Yang feel tired, drowsy, and finally fell into the river."
After a pause, Feng Yan fell into deep thought. After thinking for a few seconds, he said, "Everyone must know the conclusion. Only very close people can understand Zhou Yang's living habits so well and secretly add this song to it." In the playlist, this person is undoubtedly Cheng Fei. But we have already analyzed that Cheng Fei is not the real murderer, at best, he is an accomplice who covers up afterwards. She subjectively never wants Zhou Yang to die, so she secretly changed the song The steps should not be done by Cheng Fei, so...who could it be?"
After listening to Feng Yan's analysis, Wu Yu felt much brighter. He said, "Don't worry Feng Yan, the investigation has reached this point. Let's first check the origin of this song, and then take Cheng Fei to the bureau for interrogation. I'm sure There will be clues. Even if she didn't play this song, as a cover-up for the real culprit, she must also know who the real culprit is. Before, I didn't dare to rigorously interrogate because there was not too much evidence, but now the evidence is almost there. If these analysis results are put on the table, her psychological defenses will definitely be broken."
Time came to evening, and the police interrogated Cheng Fei all afternoon. Surprisingly, as soon as the police laid out the evidence, Cheng Fei immediately admitted that she had done it. There was no second person or so-called accomplice. But through Feng Yan and Wu Yu's handling of the case, the police already had evidence that she was not the real culprit, so they spent the whole afternoon with Cheng Fei trying to get her to reveal who the real culprit was, but Cheng Fei kept denying it. There was a second person involved, who only said that she was responsible for all this. The process was exactly the same as the investigation process. She secretly put the song into the playlist, calculated the time for Zhou Yang to go to the bridge, and made him tired. He drove and then rushed into the river and died.
The entire interrogation process was extremely depressing. The police could clearly feel that Cheng Fei knew who the real culprit was and was trying to take the blame alone. She just didn't say who the real culprit was.
Just when the interrogation of Cheng Fei in the bureau had reached its peak, news came from Shanghai that Fan Qihao actually admitted that he was the real murderer.
