Lin Xi brought the surveillance footage to the police station.
Zhang Xian personally reviewed it.
That night, Chen Xiao was at home the entire time.
Towards midnight, Chen Xiao sat in the yard.
The angle of the surveillance clearly showed Chen Xiao lying on a lounge chair all night!
Nothing could prove more convincingly that Chen Xiao wasn't present at the crime scene at the time of the incident than this video.
However, after watching the video, Zhang Xian didn't immediately release Chen Xiao, but instead looked at Lin Xi:
"Since Songshanping has such evidence, then you probably have some at your home too? Who placed that knife in your home?"
Lin Xi then produced another piece of surveillance footage that Xie Wensheng had transferred to her, and said:
"Take a look yourself. Honestly, I'm unable to distinguish who it is from the figure; I probably don't know them. Also, the person was already disguised when entering, probably to avoid being seen when leaving or entering."
