Ren Hongfeng's major discovery was a video recording.
There was a surveillance camera installed in the living room of a house on the first floor opposite Gao Meimei's building.
It was originally used by parents to supervise their children's homework.
In the end, the camera happened to be facing the window that night.
He recorded the situation that night.
Chen Yan, Liang Gang, Ren Hongfeng, and the others looked at the projection nervously.
The night was dim, and although the camera was high-definition, it could only see the figure clearly, not to mention the face.
April 20th, 23:08.
In the video, a woman and a man walked into Gao Meimei's rented apartment.
Then, the lights in Gao Meimei's rented room lit up, and a figure flickered.
23:36.
Five minutes after the male figure left.
At 23:41, another figure walked into the unit building.
His face couldn't be seen clearly, but he could tell that he had long hair and was wearing a hat.
