Officer Wu interjected: "But the bullets on both of them are the same, and the time of death is about the same, which means that the murderer knows the two of them." ”

Gu Yunfei said: "The murderer knows the two of them at the same time, it's not strange!" It's normal for two unsociable people to know the same person. ”

"From the day she moved into the Cheongdam apartment until she was killed, she lived in the apartment for 2 years and 15 days, during which time almost no one visited her house, except for a man in his mid-fifties who visited her two or three times a week. Couriers and delivery people would often knock on her door, but they would only pass things through the crack in the door opened by Kuanna, and never entered. Judging from the surveillance video in the corridor of the apartment, every time a man in his fifties knocks on the door, he will open the door after a while. Occasionally, the man would open the door with the key himself. It seems that they have a close relationship. ”

Gu Yunfei said: "This man around fifty years old is the person who contacted Guo Na by text message before her death - Ming Shu, there must be nothing wrong!" ”

Luo Fei said: "It's entirely possible, the man who said on the text message that Kuanna was going to break up was called Ming Shu, and from his frequent visits to Kuanna's residence, it shows that they are lovers, and recently Kuanna proposed to break up with him." ”

Gu Yunfei said: "I am most concerned about who Guo Na and Yang Biao met on the day of their deaths. ”

Luo Fei said: "Judging from the surveillance video in the past two years, the day of Kuanna's death saw her the most people in two years: an older woman, a younger woman, a handsome young man, a courier and a flower delivery person who delivered potted plants. Yang Biao didn't go out that day, and no one came to knock on the door to look for him. The key point is that on the day of their death, from 3 p.m. to 8 a.m. this morning, the monitoring room failed, and during this time, the situation in the building was not monitored. ”

Officer Wu said: "Why did the monitoring fail when they suffered an accident? What went wrong? Could it be that someone did it on purpose? ”

Gu Yunfei said: "Let's not talk about this first, let's sort out the people that Guan Na saw that day." Judging from the chat text messages between her and Ming Shu, the slightly older woman should be Mrs. Ming Shu. Because Kuanna told Ming Shu in a text message that his wife had looked for her during the day. Kuanna also texted a man named Bai Chuan that his girlfriend Wang Huizhi had also come to her during the day, and that the young woman should be Wang Huizhi. The handsome young man, if I guessed correctly, is Shirakawa. I remember that there was an unopened package on the table in the living room of Kuanna, which was sent by the Flying Courier Company, and the courier had also seen her that day. The person who sent the flowers, when the time comes, we will ask the people in the nearby flower shop to know who the flower giver is. ”

Luo Fei said with some concern: "The older woman, just like Yun Fei said, may be Mingshu's wife, she walked for half an hour, turned back, and entered Guan Na's residence, just entered, the surveillance video was out of order, so I can't see when the older woman, the flower giver and the young woman Wang Huizhi left." Now back to why the surveillance video failed after more than 3 o'clock, is it a coincidence? ”

Luo Fei called Master Yu, who usually manages the computer room, who was in his fifties, gray-haired, and amiable.

Luo Fei asked directly: "Does the monitoring equipment usually fail?" ”

Master Yu said: "I have been working in this computer room for three years, and there have been almost no failures. ”
