Chen Xiao sat in the room.
Holding the portrait in his hand, he hadn't moved for a long time.
In the case, the only person who fit the image of a young man was Sang Xiaoming.
And Sang Xiaoming held a very special position in the case.
Because after the deceased came to Xiaozhuang South Town, he had contact with him, even having had an exchange.
However, there was no valuable information in Sang Xiaoming's testimony.
This doesn't necessarily mean that Sang Xiaoming was lying.
He is a student, and his father inviting the tenant Yuan Keyu to teach him some academic knowledge is a very reasonable thing.
However, who tampered with the surveillance at Sang Yupeng's house?
Although tampering with the surveillance is not difficult, and from watching the video, it doesn't seem like fake footage.
So, the problem with the video, or to directly say the illusion of a locked-room murder, merely involved swapping the surveillance.
The cameras on the fourth and sixth floors were swapped.
