Gu Yunfei asked nervously, "What do you see?" ”

The silver-haired grandmother bit her lip and said, "I saw a person!" ”

Gu Yunfei said excitedly: "What kind of person is he? ”

"A man in a white baseball cap and a red jacket who is climbing down the water pipe of the Cheongdam apartment." The silver-haired grandmother pointed to the white water pipe downstairs from the Cheongdam apartment and said with wide eyes, as if she had seen a ghost that night.

Gu Yunfei looked at the water pipe she was pointing to, which was the white water pipe in the window on the right of Guan Na and Yang Biao, and asked suspiciously, "That person climbed down from that floor?" ”

The silver-haired grandmother thought for a while and said: "It seems to have climbed down from the twenty floors, the building is so high, it is late at night, everyone is sleeping, the residents have no lights on in their homes, I can only see the person through the street lamps around the apartment, I am not sure exactly where he climbed down that floor." Either climb down from the 20th floor, or the 19th floor, or even a little higher. I'm not sure. ”

Gu Yunfei said: "Then do you remember when you saw that person?" ”

The silver-haired grandmother said: "I set off from home at half past one in the morning, and it should be about one forty in the morning when I get downstairs to the Qingtan apartment, and there may be a few more minutes." ”

When Gu Yunfei heard such a big clue, she couldn't help but be overjoyed and said, "Then have you seen the appearance of that person?" ”

The silver-haired grandmother said: "After the man came down, he did not come in the direction of the main road in front of the apartment, but walked to the cement ladder on the left side of the apartment, and left the back of the apartment by detour. Looking at his back, he is a tall and thin man, who should be about 1.8 meters. That day, I had dinner very early, watched TV until more than 10 o'clock, felt a little sleepy, and went to bed, after really going to bed, I couldn't sleep over and over, I always felt that there was an ominous atmosphere outside the window, but I didn't know that there was a murder in the Qingtan apartment near my community. If I had known about the murder that day, I would have pursued the man who had climbed down the pipe, and brought him back to you police, and interrogated him if he had anything to do with the murder. ”

Gu Yunfei said: "Fortunately, Grandma, you didn't catch up, if that person is really a murderer, you will definitely not be able to beat him if you catch up, he will not be caught - he may even hurt you." ”

The silver-haired grandmother said: "Okay, police girl, I told you all such an important matter, I hope it will help you solve the case, I'm leaving." I'm going to buy a potted plant and put it on my balcony, and if I have insomnia in the future, I'll get up and look at my potted plants, don't run around alone late at night, people with ghosts come out at night to do bad things, I don't want to meet ......"

Gu Yunfei was stunned, the silver-haired grandmother had already gone away, and she didn't even know.

Luo Fei came over and patted her on the shoulder, and she suddenly came back to her senses and looked at Luo Fei with a complicated expression.

Luo Fei asked expectantly, "What did Grandma tell you?" ”

Gu Yunfei said: "This is simply an earth-shattering evidence. ”

Luo Fei said: "Tell me quickly, what's wrong?" ”

Gu Yunfei pointed to the white water pipe that went downstairs next to the window of Guan Na and Yang Biao's room, and said, "You can see it clearly, that white water pipe." On the day of the murder, Grandma said that it was 1:40 a.m., which might have taken a few more minutes, and when she passed downstairs, she saw a tall thin man wearing a white baseball cap and a red jacket, probably climbing down the 20th floor down the water pipe, and then leaving like a ghost through the steps on the left side of the apartment. ”
